It reads excerpts rather than whole files, so it locates code; it doesn't review or audit it. Specify search breadth: \"medium\" for moderate exploration, \"very thorough\" for multiple locations and naming conventions.

(Tools: *)","- let-fate-decide:draw: Draw the 12 Houses of the Zodiac Tarot spread and return a concise structured reading. Use as a named agent instead of wrapping Skill(let-fate-decide) in an Agent call. Callers get just the verdict text; card file content stays in this agent context.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern.

Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the

input** = `input_tokens` + `cache_creation_input_tokens` (tokens actually processed fresh, including cache writes).\n- **Input** = cached + uncached, and **total** = input + output. This mapping is documented in a comment at the top of the script.\n\nImplementation details: it streams each file line-by-line with `readline` rather than slurping (some session files are large), skips malformed or usage-less lines, and only needs Node's standard library.

directory for this skill: /tmp/claude-1000/bundled-skills/2.1.201/7d09c50b2089c1645d54ad8f4066a837/claude-api\n\n# Building LLM-Powered Applications with Claude\n\nThis skill helps you build LLM-powered applications with Claude. Choose the right surface based on your needs, detect the project language, then read the relevant language-specific documentation.\n\n## Before You Start\n\nScan the target file (or, if no target file, the prompt and project) for non-Anthropic provider markers — `import openai`, `from openai`, `langchain_openai`, `OpenAI(`, `gpt-4`, `gpt-5`, file names like `agent-openai.py` or `*-generic.py`, or any explicit instruction to keep the code provider-neutral. If you find any, stop and tell the user that this skill produces Claude/Anthropic SDK code; ask whether they want to switch the file to Claude or want a non-Claude implementation. Do not edit a non-Anthropic file with Anthropic SDK calls.\n\n## Output Requirement\n\nWhen the user asks you to add, modify, or implement a Claude feature, your code must call Claude through one of:\n\n1. **The official Anthropic SDK** for the project's language (`anthropic`, `@anthropic-ai/sdk`, `com.anthropic.*`, etc.). This is the default whenever a supported SDK exists for the project.\n2. **Raw HTTP** (`curl`, `requests`, `fetch`, `httpx`, etc.) — only when the user explicitly asks for cURL/REST/raw HTTP, the project is a shell/cURL project, or the language has no official SDK.\n\nNever mix the two — don't reach for `requests`/`fetch` in a Python or TypeScript project just because it feels lighter. Never fall back to OpenAI-compatible shims.\n\n**Never guess SDK usage.** Function names, class names, namespaces, method signatures, and import paths must come from explicit documentation — either the `{lang}/` files in this skill or the official SDK repositories or documentation links listed in `shared/live-sources.md`. If the binding you need is not explicitly documented in the skill files, WebFetch the relevant SDK repo from `shared/live-sources.md` before writing code. Do not infer Ruby/Java/Go/PHP/C# APIs from cURL shapes or from another language's SDK.\n\n**If WebFetch or repository access fails** (network restricted, timeouts, clone blocked): do not keep retrying — write code from the patterns and namespace/package tables in the `{lang}/` file, run the compiler or interpreter on it, and iterate on the error output. For statically-typed SDKs (C#, Java, Go) a compile-fix loop against local errors reaches working code faster than blocked network research.\n\n## Defaults\n\nUnless the user requests otherwise:\n\nFor the Claude model version, please use Claude Opus 4.8, which you can access via the exact model string `claude-opus-4-8`. Please default to using adaptive thinking (`thinking: {type: \"adaptive\"}`) for anything remotely complicated. And finally, please default to streaming for any request that may involve long input, long output, or high `max_tokens` — it prevents hitting request timeouts. Use the SDK's `.get_final_message()` / `.finalMessage()` helper to get the complete response if you don't need to handle individual stream events\n\n## ⚠️ API Drift — Your Training Prior May Be Stale\n\nSeveral common Claude API shapes changed in 2025–2026. If you recall a pattern from training, verify it against the `{lang}/` files in this skill before writing — the rows below are the most frequent drift points:\n\n| Area | Stale prior | Current API |\n|---|---|---|\n| Extended thinking | `thinking: {type: \"enabled\", budget_tokens: N}` | On Claude 4.6+ models: `thinking: {type: \"adaptive\"}`. `budget_tokens` is deprecated on Opus 4.6 / Sonnet 4.6 and **rejected with a 400** on Fable 5 / Sonnet 5 / Opus 4.8 / 4.7. Pre-4.6 models still use `budget_tokens`. |\n| Web search / web fetch tool type | `web_search_20250305`, `web_fetch_20250910` | `web_search_20260209`, `web_fetch_20260209` (dynamic filtering) on Opus 4.8/4.7/4.6, Sonnet 5, and Sonnet 4.6. Older models keep the basic variants; on Vertex AI only basic `web_search_20250305` is available (web fetch is not on Vertex) — see the Server Tools QR below. |\n| PHP parameter names | snake_case wire names as named args (`max_tokens`) | Top-level named args are camelCase (`maxTokens`). Nested array keys vary by feature (e.g. `'taskBudget'`, `'skillID'`, `'mcp_server_name'`) — copy the exact key from the documented example; do not bulk-convert. |\n\nThe `{lang}/` files in this skill are authoritative over recalled patterns.\n\n---\n\n## Subcommands\n\nIf the User Request at the bottom of this prompt is a bare subcommand string (no prose), search every **Subcommands** table in this document — including any in sections appended below — and follow the matching Action column directly. This lets users invoke specific flows via `/claude-api <subcommand>`. If no table in the document matches, treat the request as normal prose.\n\n| Subcommand | Action |\n|---|---|\n| `migrate` | Migrate existing Claude API code to a newer model. **Read `shared/model-migration.md` immediately** and follow it in order: Step 0 (confirm scope — ask which files/directories before any edit), Step 1 (classify each file), then the per-target breaking-changes section. Do not summarize the guide — execute it. If the user did not name a target model, ask which model to migrate to in the same turn as the scope question. |\n\n---\n\n## Language Detection\n\nBefore reading code examples, determine which language the user is working in:\n\n1. **Look at project files** to infer the language:\n\n - `*.py`, `requirements.txt`, `pyproject.toml`, `setup.py`, `Pipfile` → **Python** — read from `python/`\n - `*.ts`, `*.tsx`, `package.json`, `tsconfig.json` → **TypeScript** — read from `typescript/`\n - `*.js`, `*.jsx` (no `.ts` files present) → **TypeScript** — JS uses the same SDK, read from `typescript/`\n - `*.java`, `pom.xml`, `build.gradle` → **Java** — read from `java/`\n - `*.kt`, `*.kts`, `build.gradle.kts` → **Java** — Kotlin uses the Java SDK, read from `java/`\n - `*.scala`, `build.sbt` → **Java** — Scala uses the Java SDK, read from `java/`\n - `*.go`, `go.mod` → **Go** — read from `go/`\n - `*.rb`, `Gemfile` → **Ruby** — read from `ruby/`\n - `*.cs`, `*.csproj` → **C#** — read from `csharp/`\n - `*.php`, `composer.json` → **PHP** — read from `php/`\n\n2. **If multiple languages detected** (e.g., both Python and TypeScript files):\n\n - Check which language the user's current file or question relates to\n - If still ambiguous, ask: \"I detected both Python and TypeScript files. Which language are you using for the Claude API integration?\"\n\n3. **If language can't be inferred** (empty project, no source files, or unsupported language):\n\n - Use AskUserQuestion with options: Python, TypeScript, Java, Go, Ruby, cURL/raw HTTP, C#, PHP\n - If AskUserQuestion is unavailable, default to Python examples and note: \"Showing Python examples. Let me know if you need a different language.\"\n\n4. **If unsupported language detected** (Rust, Swift, C++, Elixir, etc.):\n\n - Suggest cURL/raw HTTP examples from `curl/` and note that community SDKs may exist\n - Offer to show Python or TypeScript examples as reference implementations\n\n5. **If user needs cURL/raw HTTP examples**, read from `curl/`.\n\n### Language-Specific Feature Support\n\n| Language | Tool Runner | Managed Agents | Notes |\n| ---------- | ----------- | -------------- | ------------------------------------- |\n| Python | Yes (beta) | Yes (beta) | Full support — `@beta_tool` decorator |\n| TypeScript | Yes (beta) | Yes (beta) | Full support — `betaZodTool` + Zod |\n| Java | Yes (beta) | Yes (beta) | Beta tool use with annotated classes |\n| Go | Yes (beta) | Yes (beta) | `BetaToolRunner` in `toolrunner` pkg |\n| Ruby | Yes (beta) | Yes (beta) | `BaseTool` + `tool_runner` in beta |\n| C# | Yes (beta) | Yes (beta) | `BetaToolRunner` + raw JSON schema |\n| PHP | Yes (beta) | Yes (beta) | `BetaRunnableTool` + `toolRunner()` |\n| cURL | N/A | Yes (beta) | Raw HTTP, no SDK features |\n\n> **Managed Agents code examples**: dedicated language-specific READMEs are provided for Python, TypeScript, Go, Ruby, PHP, Java, and cURL (`{lang}/managed-agents/README.md`, `curl/managed-agents.md`). Read your language's README plus the language-agnostic `shared/managed-agents-*.md` concept files. **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.create` and pass it to every subsequent `sessions.create`; do not call `agents.create` in the request path. The Anthropic CLI (`ant`) is one convenient way to create agents and environments from version-controlled YAML — see `shared/anthropic-cli.md`. If a binding you need isn't shown in the README, WebFetch the relevant entry from `shared/live-sources.md` rather than guess. C# has beta Managed Agents support via `client.Beta.Agents` and related namespaces.\n\n---\n\n## Which Surface Should I Use?\n\n> **Start simple.** Default to the simplest tier that meets your needs. Single API calls and workflows handle most use cases — only reach for agents when the task genuinely requires open-ended, model-driven exploration.\n\n| Use Case | Tier | Recommended Surface | Why |\n| ----------------------------------------------- | --------------- | ------------------------- | ------------------------------------------------------------ |\n| Classification, summarization, extraction, Q&A | Single LLM call | **Claude API** | One request, one response |\n| Batch processing or embeddings | Single LLM call | **Claude API** | Specialized endpoints |\n| Multi-step pipelines with code-controlled logic | Workflow | **Claude API + tool use** | You orchestrate the loop |\n| Custom agent with your own tools | Agent | **Claude API + tool use** | Maximum flexibility |\n| Server-managed stateful agent with workspace | Agent | **Managed Agents** | Anthropic runs the loop and hosts the tool-execution sandbox |\n| Persisted, versioned agent configs | Agent | **Managed Agents** | Agents are stored objects; sessions pin to a version |\n| Long-running multi-turn agent with file mounts | Agent | **Managed Agents** | Per-session containers, SSE event stream, Skills + MCP |\n\n> **Note:** Managed Agents is the right choice when you want Anthropic to run the agent loop *and* host the container where tools execute — file ops, bash, code execution all run in the per-session workspace. If you want to host the compute yourself or run your own custom tool runtime, Claude API + tool use is the right choice — use the tool runner for automatic loop handling, or the manual loop for fine-grained control (approval gates, custom logging, conditional execution).\n\n> **Cloud-provider access.** **Claude Platform on AWS** is Anthropic-operated with same-day API parity — see `shared/claude-platform-on-aws.md` for client setup. For per-feature availability on **Claude Platform on AWS**, **Amazon Bedrock**, **Google Vertex AI**, and **Microsoft Foundry**, see `shared/platform-availability.md` — that table is the single source of truth in this skill; do not infer availability from anywhere else.\n\n### Decision Tree\n\n```\nWhat does your application need?\n\n0. Which provider?\n ├── First-party API or Claude Platform on AWS → continue (full surface available; per-feature exceptions in shared/platform-availability.md).\n └── Amazon Bedrock, Google Vertex AI, or Microsoft Foundry → Claude API (+ tool use for agents); see shared/platform-availability.md for per-feature support.\n\n1. Single LLM call (classification, summarization, extraction, Q&A)\n └── Claude API — one request, one response\n\n2. Do you want Anthropic to run the agent loop and host a per-session\n container where Claude executes tools (bash, file ops, code)?\n └── Yes → Managed Agents — server-managed sessions, persisted agent configs,\n SSE event stream, Skills + MCP, file mounts.\n Examples: \"stateful coding agent with a workspace per task\",\n \"long-running research agent that streams events to a UI\",\n \"agent with persisted, versioned config used across many sessions\"\n\n3. Workflow (multi-step, code-orchestrated, with your own tools)\n └── Claude API with tool use — you control the loop\n\n4. Open-ended agent (model decides its own trajectory, your own tools, you host the compute)\n └── Claude API agentic loop (maximum flexibility)\n```\n\n### Should I Build an Agent?\n\nBefore choosing the agent tier, check all four criteria:\n\n- **Complexity** — Is the task multi-step and hard to fully specify in advance? (e.g., \"turn this design doc into a PR\" vs. \"extract the title from this PDF\")\n- **Value** — Does the outcome justify higher cost and latency?\n- **Viability** — Is Claude capable at this task type?\n- **Cost of error** — Can errors be caught and recovered from? (tests, review, rollback)\n\nIf the answer is \"no\" to any of these, stay at a simpler tier (single call or workflow).\n\n---\n\n## Architecture\n\nEverything goes through `POST /v1/messages`. Tools and output constraints are features of this single endpoint — not separate APIs.\n\n**User-defined tools** — You define tools (via decorators, Zod schemas, or raw JSON), and the SDK's tool runner handles calling the API, executing your functions, and looping until Claude is done. For full control, you can write the loop manually.\n\n**Server-side tools** — Anthropic-hosted tools that run on Anthropic's infrastructure. Code execution is fully server-side (declare it in `tools`, Claude runs code automatically). Computer use can be server-hosted or self-hosted.\n\n**Structured outputs** — Constrains the Messages API response format (`output_config.format`) and/or tool parameter validation (`strict: true`). The recommended approach is `client.messages.parse()` which validates responses against your schema automatically. Note: the old `output_format` parameter is deprecated; use `output_config: {format: {...}}` on `messages.create()`.\n\n**Supporting endpoints** — Batches (`POST /v1/messages/batches`), Files (`POST /v1/files`), Token Counting (`POST /v1/messages/count_tokens` — see `shared/token-counting.md`), and Models (`GET /v1/models`, `GET /v1/models/{id}` — live capability/context-window discovery) feed into or support Messages API requests.\n\n---\n\n## Current Models (cached: 2026-06-24)\n\n| Model | Model ID | Context | Input $/1M | Output $/1M |\n| ----------------- | ------------------- | -------------- | ---------- | ----------- |\n| Claude Fable 5 | `claude-fable-5` | 1M | $10.00 | $50.00 |\n| Claude Mythos 5 (Project Glasswing only) | `claude-mythos-5` | 1M | $10.00 | $50.00 |\n| Claude Opus 4.8 | `claude-opus-4-8` | 1M | $5.00 | $25.00 |\n| Claude Opus 4.7 | `claude-opus-4-7` | 1M | $5.00 | $25.00 |\n| Claude Opus 4.6 | `claude-opus-4-6` | 1M | $5.00 | $25.00 |\n| Claude Sonnet 5 | `claude-sonnet-5` | 1M | $3.00 ($2.00 intro through 2026-08-31) | $15.00 ($10.00 intro) |\n| Claude Sonnet 4.6 | `claude-sonnet-4-6` | 1M | $3.00 | $15.00 |\n| Claude Haiku 4.5 | `claude-haiku-4-5` | 200K | $1.00 | $5.00 |\n\n**ALWAYS use `claude-opus-4-8` unless the user explicitly names a different model.** This is non-negotiable. Do not use `claude-sonnet-5`, `claude-sonnet-4-6`, or any other model unless the user literally says \"use sonnet\" or \"use haiku\". Never downgrade for cost — that's the user's decision, not yours. Use `claude-fable-5` only when the user explicitly asks for Claude Fable 5, \"fable\", or Anthropic's most capable model — it has different API behavior than the Opus family (see below) and pricing that exceeds Opus-tier.\n\n### Claude Fable 5 (`claude-fable-5`) — most capable widely released model\n\nClaude Fable 5 is Anthropic's most capable widely released model, for the most demanding reasoning and long-horizon agentic work. **Claude Mythos 5** (`claude-mythos-5`) offers the same capabilities, pricing, and API surface through Project Glasswing (participation is the only way to access it), succeeding the invitation-only Claude Mythos Preview (`claude-mythos-preview`) — everything below applies to both models. 1M context window (the maximum is also the default), 128K max output. Key API differences from Opus-tier — see `shared/model-migration.md` → Migrating to Claude Fable 5 for details:\n\n- **Thinking is always on** — omit the `thinking` parameter entirely (or send `{type: \"adaptive\"}`). Any other explicit configuration is rejected: `{type: \"disabled\"}` and `{type: \"enabled\", budget_tokens: N}` both return a 400. Control depth with `output_config.effort` (supports `low` through `xhigh` and `max`).\n- **The raw chain of thought is never returned** — responses carry regular `thinking` blocks (not `redacted_thinking`): `display: \"summarized\"` returns a readable summary, `\"omitted\"` (the default) leaves the `thinking` field as an empty string. Replay rules: pass thinking blocks back exactly as received on the same model (including empty-text blocks — the API rejects *modified* blocks, not read ones); a **different** model **drops** them from the prompt (typically silently — not an error; the drop happens before pricing, so dropped blocks aren't billed and there's nothing to strip). Regular thinking blocks from other models replay across models freely.\n- **Tokenizer** — same tokenizer as Opus 4.8 (introduced with Opus 4.7). Token counts are roughly unchanged when migrating from Opus 4.7/4.8; per-token pricing differs. Coming from Opus 4.6, Sonnet, Haiku, or older, re-baseline with `count_tokens`.\n- **`refusal` stop reason — handle it, and opt into fallbacks by default** — safety classifiers may decline a request (HTTP 200, `stop_reason: \"refusal\"`, with a `stop_details` category). A pre-output refusal has an empty `content` array and is not billed at all; a mid-stream refusal bills the already-streamed output — discard the partial output. Always check `stop_reason` before reading `content`. Recovery is **opt-in on the API**: most Claude consumer surfaces ship with built-in Claude Opus 4.8 fallbacks, but an API request that doesn't opt in simply stops on a refusal — and false positives on benign adjacent work (security tooling, life-sciences tasks) do happen. **When you write `claude-fable-5` code, include the server-side `fallbacks` parameter by default** (`betas: [\"server-side-fallback-2026-06-01\"]` + `fallbacks: [{\"model\": \"claude-opus-4-8\"}]`; Claude API and Claude Platform on AWS): a declined request is transparently re-served by the fallback model inside the same call, with credit-style repricing applied automatically (a decline before any output isn't billed; the rescue bills at the fallback model's own rates). Tell the user you've enabled it; drop it only if they decline. The GA SDKs' client-side `BetaRefusalFallbackMiddleware` + `BetaFallbackState` handle retry everywhere server-side fallbacks aren't supported (incl. Amazon Bedrock, Vertex AI, Microsoft Foundry); fallback credit refunds the cache-switch cost of client-side retries. Code examples: the Refusal Fallbacks section of your language's claude-api doc; full semantics in the migration guide's refusal section.\n- **No assistant prefill** — same as the rest of the 4.6+ family.\n- **30-day data retention required** — Claude Fable 5 is not available under zero data retention; requests from an org whose retention configuration doesn't meet the requirement return `400 invalid_request_error`.\n- **Longer turns, different prompting** — single requests on hard tasks can run many minutes (plan timeouts/streaming/progress UX); effort sweeps should include low/medium for routine work; prompts written for prior models are often too prescriptive and reduce output quality. See `shared/model-migration.md` → Migrating to Claude Fable 5 → Behavioral shifts (prompt-tunable) for the recommended prompt snippets (anti-overplanning, no-tidying, grounded progress claims, boundaries, async sub-agents, memory, `send_to_user`).\n\n**CRITICAL: Use only the exact model ID strings from the table above — they are complete as-is. Do not append date suffixes.** For example, use `claude-sonnet-4-6`, never `claude-sonnet-4-6-20251114` or any other date-suffixed variant you might recall from training data. If the user requests an older model not in the table (e.g., \"opus 4.5\", \"sonnet 3.7\"), read `shared/models.md` for the exact ID — do not construct one yourself.\n\nA note: if any of the model strings above look unfamiliar to you, that's to be expected — that just means they were released after your training data cutoff. Rest assured they are real models; we wouldn't mess with you like that.\n\n**Live capability lookup:** The table above is cached. When the user asks \"what's the context window for X\", \"does X support vision/thinking/effort\", or \"which models support Y\", query the Models API (`client.models.retrieve(id)` / `client.models.list()`) — see `shared/models.md` for the field reference and capability-filter examples.\n\n---\n\n## Authentication (Quick Reference)\n\n**An unset `ANTHROPIC_API_KEY` does NOT mean there are no credentials.** The SDKs and the `ant` CLI resolve credentials in this order (first match wins): `ANTHROPIC_API_KEY` → `ANTHROPIC_AUTH_TOKEN` → the `ANTHROPIC_PROFILE`-selected or active OAuth profile from `ant auth login` → Workload Identity Federation env vars → the default profile on disk. A bare `Anthropic()` / `new Anthropic()` / `anthropic.NewClient()` works after `ant auth login` with no env var set.\n\n**When you need to call the API and `ANTHROPIC_API_KEY` is unset, don't ask the user for a key.** First run `ant auth status` — it shows which credential source and profile is active. If it reports an active profile:\n\n- **SDK code or `ant` CLI:** just run it. The zero-arg client constructor and every `ant …` subcommand pick up the profile automatically — no env var needed.\n- **Raw `curl` / HTTP:** get a short-lived token with `ant auth print-credentials --access-token` and send it as `Authorization: Bearer <token>` **plus** the header `anthropic-beta: oauth-2025-04-20` (OAuth tokens go on `Authorization: Bearer`, not `x-api-key:` — converting a curl from an API key is a header change, not a key swap). Always pass `--access-token`; the no-flag form prints JSON, not a bare token.\n\nOnly ask the user for a key if `ant auth status` reports no active credential source (or `ant` itself isn't installed). Suggest `ant auth login` as the first option — it stores a profile under `~/.config/anthropic/` that the SDKs read automatically — and an exported `ANTHROPIC_API_KEY` as the alternative.\n\nFull auth details (named profiles, scopes, the API-key-shadows-profile trap, refresh-token expiry): `shared/anthropic-cli.md`.\n\n---\n\n## Thinking & Effort (Quick Reference)\n\n**Fable 5 / Opus 4.8 / 4.7 / Sonnet 5 — Adaptive thinking only:** Use `thinking: {type: \"adaptive\"}`. `thinking: {type: \"enabled\", budget_tokens: N}` returns a 400 — adaptive is the only on-mode. On Opus 4.8, Opus 4.7, and Sonnet 5, `{type: \"disabled\"}` and omitting `thinking` both work (on Sonnet 5, omitting runs adaptive; on Opus 4.7/4.8, omitting runs without thinking — set `{type: \"adaptive\"}` explicitly); on Fable 5, an explicit `{type: \"disabled\"}` returns a 400 — omit the `thinking` param entirely instead. Sampling parameters (`temperature`, `top_p`, `top_k`) are also removed and will 400. Opus 4.8 keeps the same request surface as 4.7 (no new breaking changes) — see `shared/model-migration.md` → Migrating to Opus 4.8 for the behavioral re-tuning, and → Migrating to Opus 4.7 for the full breaking-change list when coming from 4.6 or earlier. Note: with `thinking` disabled, Opus 4.8 may write longer reasoning into the visible response — leave adaptive thinking on, or add a final-answer-only instruction (see the migration guide).\n**Opus 4.6 — Adaptive thinking (recommended):** Use `thinking: {type: \"adaptive\"}`. Claude dynamically decides when and how much to think. No `budget_tokens` needed — `budget_tokens` is deprecated on Opus 4.6 and Sonnet 4.6 and should not be used for new code. Adaptive thinking also automatically enables interleaved thinking (no beta header needed). **When the user asks for \"extended thinking\", a \"thinking budget\", or `budget_tokens`: always use Fable 5, Opus 4.8, 4.7, or 4.6 with `thinking: {type: \"adaptive\"}`. The concept of a fixed token budget for thinking is deprecated — adaptive thinking replaces it. Do NOT use `budget_tokens` for new 4.6/4.7/4.8 code and do NOT switch to an older model.** *Gradual-migration carve-out:* `budget_tokens` is still functional on Opus 4.6 and Sonnet 4.6 as a transitional escape hatch — if you're migrating existing code and need a hard token ceiling before you've tuned `effort`, see `shared/model-migration.md` → Transitional escape hatch. Note: this carve-out does **not** apply to Fable 5, Opus 4.7 or 4.8 — `budget_tokens` is fully removed there.\n**Effort parameter (GA, no beta header):** Controls thinking depth and overall token spend via `output_config: {effort: \"low\"|\"medium\"|\"high\"|\"max\"}` (inside `output_config`, not top-level). Default is `high` (equivalent to omitting it). `max` is supported on Fable 5, Opus 4.6 and later, Sonnet 5, and Sonnet 4.6 (not Haiku or earlier Sonnets). Opus 4.7 added `\"xhigh\"` (between `high` and `max`) — the best setting for most coding and agentic use cases on Fable 5 / Opus 4.7/4.8 / Sonnet 5, and the default in Claude Code; use a minimum of `high` for most intelligence-sensitive work. Works on Fable 5, Opus 4.5, Opus 4.6, Opus 4.7, Opus 4.8, Sonnet 5, and Sonnet 4.6. Will error on Sonnet 4.5 / Haiku 4.5. On Fable 5, Opus 4.7/4.8, and Sonnet 5, effort matters more than on any prior model in their tier — re-tune it when migrating, and run long-horizon/agentic tasks at `high`/`xhigh` with the full task spec given up front. Combine with adaptive thinking for the best cost-quality tradeoffs. Lower effort means fewer and more-consolidated tool calls, less preamble, and terser confirmations — `high` is often the sweet spot balancing quality and token efficiency; use `max` when correctness matters more than cost; use `low` for subagents or simple tasks.\n\n**Thinking display — `\"omitted\"` by default on Fable 5 / Mythos 5 / Opus 4.8 / 4.7 / Sonnet 5:** `display: \"summarized\"` returns a readable summary of the reasoning; `\"omitted\"` (the default on all five — a silent change from Opus 4.6 and Sonnet 4.6, where it was `\"summarized\"`) streams `thinking` blocks with empty text. `display` controls visibility only — thinking happens and is billed the same under every setting; the raw chain of thought is never exposed on any model. If you stream reasoning to users, the default looks like a long pause before output — set `thinking: {type: \"adaptive\", display: \"summarized\"}` explicitly. (Independent of display, echo thinking blocks back unchanged when continuing on the same model; other models silently ignore them — see the migration guide.)\n\n**Task Budgets (beta, Fable 5 / Opus 4.7 / 4.8 / Sonnet 5):** `output_config: {task_budget: {type: \"tokens\", total: N}}` tells the model how many tokens it has for a full agentic loop — it sees a running countdown and self-moderates (minimum 20,000; beta header `task-budgets-2026-03-13`). Distinct from `max_tokens`, which is an enforced per-response ceiling the model is not aware of. See `shared/model-migration.md` → Task Budgets.\n\n**Sonnet 4.6:** Supports adaptive thinking (`thinking: {type: \"adaptive\"}`). `budget_tokens` is deprecated on Sonnet 4.6 — use adaptive thinking instead.\n\n**Older models (only if explicitly requested):** If the user specifically asks for Sonnet 4.5 or another older model, use `thinking: {type: \"enabled\", budget_tokens: N}`. `budget_tokens` must be less than `max_tokens` (minimum 1024). Never choose an older model just because the user mentions `budget_tokens` — use Opus 4.8 with adaptive thinking instead.\n\n---\n\n## Compaction (Quick Reference)\n\n**Beta, Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, Sonnet 5, and Sonnet 4.6.** For long-running conversations that may exceed the 1M context window, enable server-side compaction. The API automatically summarizes earlier context when it approaches the trigger threshold (default: 150K tokens). Requires beta header `compact-2026-01-12`.\n\n**Critical:** Append `response.content` (not just the text) back to your messages on every turn. Compaction blocks in the response must be preserved — the API uses them to replace the compacted history on the next request. Extracting only the text string and appending that will silently lose the compaction state.\n\nSee `{lang}/claude-api/README.md` (Compaction section) for code examples. Full docs via WebFetch in `shared/live-sources.md`.\n\n---\n\n## Prompt Caching (Quick Reference)\n\n**Prefix match.** Any byte change anywhere in the prefix invalidates everything after it. Render order is `tools` → `system` → `messages`. Keep stable content first (frozen system prompt, deterministic tool list), put volatile content (timestamps, per-request IDs, varying questions) after the last `cache_control` breakpoint.\n\n**Mid-conversation operator instructions** (Claude Opus 4.8 only; no beta header): append `{\"role\": \"system\", ...}` to `messages[]` instead of editing top-level `system`. Preserves the cached history prefix and is the prompt-injection-safe operator channel. See `shared/prompt-caching.md` § Mid-conversation system messages.\n\n**Top-level auto-caching** (`cache_control: {type: \"ephemeral\"}` on `messages.create()`) is the simplest option when you don't need fine-grained placement. Max 4 breakpoints per request. Minimum cacheable prefix is ~1024 tokens — shorter prefixes silently won't cache.\n\n**Verify with `usage.cache_read_input_tokens`** — if it's zero across repeated requests, a silent invalidator is at work (`datetime.now()` in system prompt, unsorted JSON, varying tool set).\n\nFor placement patterns, architectural guidance, and the silent-invalidator audit checklist: read `shared/prompt-caching.md`. Language-specific syntax: `{lang}/claude-api/README.md` (Prompt Caching section).\n\n---\n\n## Fast Mode (Quick Reference)\n\n**Research preview, Opus 4.8 / 4.7 only.** Opus 4.7 fast mode is deprecated — after removal, `speed: \"fast\"` on 4.7 returns an error. Opus 4.8 is the durable fast-capable tier. Fast mode runs the same model at up to 2.5x higher output tokens per second, at premium pricing. Three things are required on every request: use the **beta** messages endpoint (`client.beta.messages.…`), pass the beta flag `fast-mode-2026-02-01`, and set `speed: \"fast\"` as a top-level request parameter (not a header, not in `extra_body`).\n\n```python\nclient.beta.messages.create(\n model=\"claude-opus-4-8\", max_tokens=4096,\n speed=\"fast\", betas=[\"fast-mode-2026-02-01\"],\n messages=[...],\n)\n```\n\n| Language | Beta flag | Speed parameter |\n|---|---|---|\n| Python | `betas=[\"fast-mode-2026-02-01\"]` | `speed=\"fast\"` |\n| TypeScript / Ruby | `betas: [\"fast-mode-2026-02-01\"]` | `speed: \"fast\"` |\n| Go | `[]anthropic.AnthropicBeta{anthropic.AnthropicBetaFastMode2026_02_01}` | `Speed: anthropic.BetaMessageNewParamsSpeedFast` |\n| Java | `.addBeta(AnthropicBeta.FAST_MODE_2026_02_01)` | `.speed(MessageCreateParams.Speed.FAST)` |\n| C# | `Betas = [\"fast-mode-2026-02-01\"]` | `Speed = Speed.Fast` (`Anthropic.Models.Beta.Messages`) |\n| PHP | `betas: ['fast-mode-2026-02-01']` | `speed: 'fast'` |\n| cURL | `anthropic-beta: fast-mode-2026-02-01` header | `\"speed\": \"fast\"` in body |\n\n`response.usage.speed` reports which speed was used. Fast mode has its own rate limit separate from standard Opus; on 429, either retry after the `retry-after` delay or drop `speed` and fall back to standard (note: switching speed invalidates prompt cache). Not available with Batch API, Priority Tier, Claude Platform on AWS, or third-party platforms.\n\n---\n\n## Task Budgets (Quick Reference)\n\n**Beta, Fable 5 / Sonnet 5 / Opus 4.8 / 4.7.** A task budget gives Claude a token ceiling for an agentic loop so it paces itself and finishes gracefully instead of being cut off. Set `task_budget` inside `output_config` on `client.beta.messages.stream(...)` with beta flag `task-budgets-2026-03-13` — use streaming so the large `max_tokens` doesn't hit HTTP timeouts:\n\n```python\nwith client.beta.messages.stream(\n model=\"claude-opus-4-8\", max_tokens=128000,\n output_config={\"effort\": \"high\", \"task_budget\": {\"type\": \"tokens\", \"total\": 64000}},\n betas=[\"task-budgets-2026-03-13\"],\n messages=[...], tools=[...],\n) as stream:\n response = stream.get_final_message()\n```\n\n`task_budget` fields: `type` (always `\"tokens\"`), `total`, and optional `remaining` (defaults to `total`). The server injects a countdown marker Claude sees during generation; the budget counts what Claude generates and the tool results it reads this turn — **not** the full history you resend each request.\n\n**Observing spend:** accumulate `response.usage.output_tokens` (plus the token count of the tool-result blocks you append) across loop iterations if you want to display progress. Leave `remaining` unset in the normal loop — the server tracks the countdown itself, and passing a client-computed `remaining` while also resending full history under-reports the budget. **Only pass `remaining`** when you compact or rewrite history between requests and the server can no longer derive prior spend.\n\n---\n\n## Provider Clients (Quick Reference)\n\nWhen targeting Claude on a third-party platform, use that platform's dedicated client class — not the first-party `Anthropic()` client with a `base_url` override. After construction the client exposes the same `messages.create` / `.stream` surface as the first-party SDK.\n\n### Amazon Bedrock\n\nUse the **Mantle** client (Messages-API Bedrock endpoint). Bedrock model IDs take an `anthropic.` prefix (e.g. `\"anthropic.claude-opus-4-8\"`). Region is required.\n\n| Language | Client |\n|---|---|\n| Python | `from anthropic import AnthropicBedrockMantle` → `AnthropicBedrockMantle(aws_region=\"…\")` |\n| TypeScript | `import { AnthropicBedrockMantle } from \"@anthropic-ai/bedrock-sdk\"` → `new AnthropicBedrockMantle({ awsRegion: \"…\" })` |\n| Go | `bedrock.NewMantleClient(ctx, bedrock.MantleClientConfig{ AWSRegion: \"…\" })` |\n| Java | `AnthropicOkHttpClient.builder().backend(BedrockMantleBackend.fromEnv()).build()` (from `com.anthropic.bedrock.backends`) |\n| C# | `new AnthropicBedrockMantleClient(new() { AwsRegion = \"…\" })` (package `Anthropic.Bedrock`) |\n| PHP | `use Anthropic\\Bedrock\\MantleClient;` → `new MantleClient(awsRegion: '…')` |\n| Ruby | `Anthropic::BedrockMantleClient.new(aws_region: \"…\")` |\n\n`AnthropicBedrock` / `BedrockClient` / `BedrockBackend` (without `Mantle`) are the legacy `bedrock-runtime` InvokeModel path — prefer the Mantle client for new code.\n\n### Microsoft Foundry\n\n| Language | Client |\n|---|---|\n| Python | `from anthropic import AnthropicFoundry` → `AnthropicFoundry(api_key=…, resource=\"…\")` |\n| TypeScript | `import AnthropicFoundry from \"@anthropic-ai/foundry-sdk\"` → `new AnthropicFoundry({ … })` |\n| Java | `AnthropicOkHttpClient.builder().backend(FoundryBackend.fromEnv()).build()` (from `com.anthropic.foundry.backends`) |\n| C# | `new AnthropicFoundryClient(new AnthropicFoundryApiKeyCredentials(…))` (package `Anthropic.Foundry`) |\n| PHP | `Foundry\\Client::withCredentials(…)` |\n\nThe Go and Ruby SDKs do not currently support Foundry. For Ruby, use the standard `Anthropic::Client.new(base_url: \"<foundry endpoint>\")` as a fallback (Entra ID auth is not built in). For Claude Platform on AWS, see `shared/claude-platform-on-aws.md`.\n\n### Google Cloud Vertex AI\n\nTwo required constructor args: GCP `project_id` and `region`. Vertex model IDs take **no prefix** — current-generation models (Opus 4.8/4.7/4.6, Sonnet 5, Sonnet 4.6) use the bare first-party ID (e.g. `\"claude-opus-4-8\"`); dated-snapshot models use an `@` version separator (e.g. `claude-opus-4-5@20251101`, **not** `claude-opus-4-5-20251101`). Auth is GCP ADC (`gcloud auth application-default login`); no Anthropic API key. `region` can be `\"global\"` (recommended), a multi-region (`\"us\"`/`\"eu\"`), or a specific region. After construction, use the same `messages.create` / `.stream` surface.\n\n| Language | Client |\n|---|---|\n| Python | `from anthropic import AnthropicVertex` → `AnthropicVertex(project_id=\"…\", region=\"…\")` (install `\"anthropic[vertex]\"`) |\n| TypeScript | `import { AnthropicVertex } from \"@anthropic-ai/vertex-sdk\"` → `new AnthropicVertex({ projectId, region })` |\n| Go | `import \"github.com/anthropics/anthropic-sdk-go/vertex\"` → `anthropic.NewClient(vertex.WithGoogleAuth(ctx, region, projectID))` |\n| Java | `AnthropicOkHttpClient.builder().backend(VertexBackend.builder().region(\"…\").project(\"…\").build()).build()` (from `com.anthropic.vertex.backends`) |\n| C# | `new AnthropicClient { Backend = new VertexBackend(projectId, region) }` (package `Anthropic.Vertex`) |\n| PHP | `use Anthropic\\Vertex;` → `Vertex\\Client::fromEnvironment(location: '…', projectId: '…')` — note `location`, not `region` |\n| Ruby | `Anthropic::VertexClient.new(region: \"…\", project_id: \"…\")` |\n\n---\n\n## Context Editing (Quick Reference)\n\n**Beta.** Context editing **clears** old tool results or thinking blocks from the conversation before the model sees it; it is **not compaction** (which summarizes). On `client.beta.messages.*` with beta `context-management-2025-06-27`, pass `context_management.edits` with a strategy type:\n\n```python\nclient.beta.messages.create(\n model=\"claude-opus-4-8\", max_tokens=4096,\n betas=[\"context-management-2025-06-27\"],\n context_management={\"edits\": [{\"type\": \"clear_tool_uses_20250919\"}]},\n tools=[...], messages=[...],\n)\n```\n\nStrategy types: `clear_tool_uses_20250919` (clears old tool results; optional `clear_tool_inputs: true` also clears the tool_use params) and `clear_thinking_20251015` (clears thinking blocks). Do **not** use `compact_20260112` or beta `compact-2026-01-12` — those are the separate compaction feature.\n\n---\n\n## Mid-Conversation System Messages (Quick Reference)\n\n**Claude Opus 4.8 only; no beta header.** Append `{\"role\": \"system\", \"content\": \"…\"}` to the `messages` array (not the top-level `system` field) to add an operator instruction mid-conversation without invalidating the cached prefix. Use the regular `client.messages.create` — there is no beta. A mid-conversation system message must follow a `user` message (or an `assistant` message ending in server-tool use), and must be either the last entry in `messages` or be followed by an `assistant` turn — it cannot be `messages[0]`. Availability: `shared/platform-availability.md`. See `shared/prompt-caching.md` § Mid-conversation system messages.\n\n---\n\n## Managed Agents (Beta)\n\n**Managed Agents** is a third surface: server-managed stateful agents with Anthropic-hosted tool execution. You create a persisted, versioned Agent config (`POST /v1/agents`), then start Sessions that reference it. Each session provisions a container as the agent's workspace — bash, file ops, and code execution run there; the agent loop itself runs on Anthropic's orchestration layer and acts on the container via tools. The session streams events; you send messages and tool results back.\n\nAvailability: `shared/platform-availability.md`. For agents on Bedrock / Vertex / Foundry (where Managed Agents is unsupported), use Claude API + tool use.\n\n**Mandatory flow:** Agent (once) → Session (every run). `model`/`system`/`tools` live on the agent, never the session. See `shared/managed-agents-overview.md` for the full reading guide, beta headers, and pitfalls.\n\n**Beta headers:** `managed-agents-2026-04-01` — the SDK sets this automatically for all `client.beta.{agents,environments,sessions,vaults,memory_stores,deployments,deployment_runs}.*` calls. Skills API uses `skills-2025-10-02` and Files API uses `files-api-2025-04-14`, but you don't need to explicitly pass those in for endpoints other than `/v1/skills` and `/v1/files`.\n\n**Subcommands** — invoke directly with `/claude-api <subcommand>`:\n\n| Subcommand | Action |\n|---|---|\n| `managed-agents-onboard` | Walk the user through setting up a Managed Agent from scratch. **Read `shared/managed-agents-onboarding.md` immediately** and follow its interview script: **describe → configure the agent (propose, don't interrogate) → environment → session** (same arc as the Console quickstart, auth deferred to the session step) — defaults and inline suggestions do the work, with a silent viability gate (job vs tools/credentials/data) before any code is emitted. Do not summarize — run the interview. |\n\n**Reading guide:** Start with `shared/managed-agents-overview.md`, then the topical `shared/managed-agents-*.md` files (core, environments, tools, events, outcomes, multiagent, webhooks, memory, scheduled-deployments, client-patterns, onboarding, api-reference). For Python, TypeScript, Go, Ruby, PHP, and Java, read `{lang}/managed-agents/README.md` for code examples. For cURL, read `curl/managed-agents.md`. **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.create` and pass it to every subsequent `sessions.create`; do not call `agents.create` in the request path. The Anthropic CLI (`ant`) is one convenient way to create agents and environments from version-controlled YAML — see `shared/anthropic-cli.md`. If a binding you need isn't shown in the language README, WebFetch the relevant entry from `shared/live-sources.md` rather than guess. C# has beta Managed Agents support via `client.Beta.Agents` and related namespaces.\n\n**When the user wants to set up a Managed Agent from scratch** (e.g. \"how do I get started\", \"walk me through creating one\", \"set up a new agent\"): read `shared/managed-agents-onboarding.md` and run its interview — same flow as the `managed-agents-onboard` subcommand.\n\n**When the user asks \"how do I write the client code for X\":** reach for `shared/managed-agents-client-patterns.md` — covers lossless stream reconnect, `processed_at` queued/processed gate, interrupt, `tool_confirmation` round-trip, the correct idle/terminated break gate, post-idle status race, stream-first ordering, file-mount gotchas, keeping credentials host-side via custom tools, etc.\n\n**When the user wants the agent to run on a schedule** (cron, \"every night\", \"weekly report\"): read `shared/managed-agents-scheduled-deployments.md` — deployments fire sessions autonomously on a cron cadence, with per-firing run records and lifecycle controls (pause/unpause/archive).\n\n---\n\n## Server Tools (Quick Reference)\n\nServer-side tools run on Anthropic's infrastructure — no client-side execution loop. Declare in `tools`; results arrive as content blocks in the same response. **No beta header** unless noted. **Prefer the latest type variant your model supports.** The `_20260209` web search / web fetch variants below (dynamic filtering) require Opus 4.8/4.7/4.6, Sonnet 5, or Sonnet 4.6; the basic variants for older models are listed after the table.\n\n| Tool | `type` | `name` | Key optional params | Result block type |\n|---|---|---|---|---|\n| Web search | `web_search_20260209` | `web_search` | `max_uses`, `allowed_domains`/`blocked_domains`, `user_location` | `web_search_tool_result` → `.content` is a list of `web_search_result` |\n| Web fetch | `web_fetch_20260209` | `web_fetch` | `max_uses`, `allowed_domains`/`blocked_domains`, `citations`, `max_content_tokens` | `web_fetch_tool_result` → `.content` is a `web_fetch_result` with a `document` block |\n| Code execution | `code_execution_20260521` | `code_execution` | none | `bash_code_execution_tool_result` → `.content.stdout` / `.stderr` / `.return_code` |\n| Tool search (regex) | `tool_search_tool_regex_20251119` | `tool_search_tool_regex` | mark other tools `defer_loading: true` | `tool_search_tool_result` |\n| Tool search (BM25) | `tool_search_tool_bm25_20251119` | `tool_search_tool_bm25` | mark other tools `defer_loading: true` | `tool_search_tool_result` |\n\n`web_search_20260209` / `web_fetch_20260209` have built-in dynamic filtering — code execution runs under the hood, so do **not** separately declare `code_execution` in `tools` (a second execution environment confuses the model). For models older than Opus 4.6 / Sonnet 4.6, use the basic variants `web_search_20250305` / `web_fetch_20250910` instead; on Vertex AI only basic `web_search_20250305` is available. `code_execution_20260120` (REPL persistence + programmatic tool calling) runs on Opus 4.5+ / Sonnet 4.5+. **Go SDK only**: `code_execution_20260521` lives under `client.Beta.Messages.New` with `Betas: []anthropic.AnthropicBeta{\"code-execution-2025-08-25\"}` (other languages use plain `client.messages.create`); `code_execution_20260120` uses the non-beta `client.Messages.New` in Go like everywhere else. Web fetch only fetches URLs already present in the conversation. Provider availability varies by tool — see `shared/platform-availability.md`. See `shared/tool-use-concepts.md` for `pause_turn` handling.\n\n## Document & File Input (Quick Reference)\n\n**PDF (base64, no beta):** `{\"type\": \"document\", \"source\": {\"type\": \"base64\", \"media_type\": \"application/pdf\", \"data\": <b64 string>}}` in user content, placed before the text block. Base64 string must have no newlines. Limits: 32 MB request, 600 pages (100 for 200k-context models). Java: `ContentBlockParam.ofDocument(DocumentBlockParam... Base64PdfSource.builder().data(...))`.\n\n**Files API (beta `files-api-2025-04-14`):** upload via `client.beta.files.upload(...)` → response `id` is the `file_id`. Reference it as `{\"type\": \"document\", \"source\": {\"type\": \"file\", \"file_id\": \"...\"}}` for PDF/text, or `{\"type\": \"image\", ...}` for images — the content-block type must match the file's MIME type. The beta header is required on **both** the upload and the `messages.create` that references the file. Availability: `shared/platform-availability.md`.\n\n**Citations (no beta):** set `citations: {enabled: true}` on each `document` content block (all or none). Response splits into multiple `text` blocks; cited blocks carry a `citations` array. Each citation has `cited_text`, `document_index`, `document_title`, and a location by `type`: `char_location` (`start_char_index`/`end_char_index`) for plain text, `page_location` (`start_page_number`/`end_page_number`, 1-indexed) for PDF, `content_block_location` for custom content. Incompatible with `output_config.format`.\n\n## Tool Use Patterns (Quick Reference)\n\n**Strict tool use (no beta):** set `strict: true` as a top-level field on the tool definition (alongside `name`/`description`/`input_schema`), **not** on `tool_choice`. Schema must have `additionalProperties: false` + `required`. Guarantees `tool_use.input` validates exactly. Go: `Strict: anthropic.Bool(true)` + `additionalProperties` via `InputSchema.ExtraFields`; Java: `.strict(true)` + `.putAdditionalProperty(\"additionalProperties\", JsonValue.from(false))`.\n\n**Parallel tool use (default on):** one assistant message may contain multiple `tool_use` blocks. Execute them concurrently, then return **all** `tool_result` blocks in a **single** user message (don't split across multiple messages). For a failed tool, return `tool_result` with `is_error: true` — don't drop it.\n\n**Tool Runner (SDK beta helper):** drives the tool-call loop for you via `client.beta.messages.*`. Python: `@beta_tool` decorator + `client.beta.messages.tool_runner(...)` → `runner.until_done()`. TypeScript: `betaZodTool({...})` from `@anthropic-ai/sdk/helpers/beta/zod` + `client.beta.messages.toolRunner(...)` → `await runner`. Go: `toolrunner.NewBetaToolFromJSONSchema(...)` + `client.Beta.Messages.NewToolRunner(...)` → `.RunToCompletion(ctx)`. Java requires `.addBeta(\"structured-outputs-2025-11-13\")`. Ruby: `Anthropic::BaseTool` subclass + `client.beta.messages.tool_runner(...)`. PHP: `BetaRunnableTool` + `->toolRunner(...)`. C#: raw JSON-schema tools + `BetaToolRunner` via `client.Beta.Messages.ToolRunner(...)`.\n\n**Programmatic tool calling (no beta header):** Claude calls your custom tool from inside code execution. Add `{\"type\": \"code_execution_20260120\", \"name\": \"code_execution\"}` **and** set `\"allowed_callers\": [\"code_execution_20260120\"]` on your custom tool. Opus 4.5+ / Sonnet 4.5+ (availability: `shared/platform-availability.md`). When responding to a pending programmatic call, the user message must contain **only** `tool_result` blocks (no text). Not compatible with `strict: true`, `disable_parallel_tool_use`, forced `tool_choice`, or MCP tools.\n\n## Other API Surfaces (Quick Reference)\n\n**Message Batches (no beta; availability: `shared/platform-availability.md`):** `client.messages.batches.create(requests=[{custom_id, params}, ...])` → poll `client.messages.batches.retrieve(id).processing_status` until `\"ended\"` → stream `client.messages.batches.results(id)`. Each result has `.custom_id` + `.result.type` (`succeeded`/`errored`/`canceled`/`expired`); on success read `.result.message.content`. Python wraps requests as `Request(custom_id=..., params=MessageCreateParamsNonStreaming(...))`. Results arrive in **any order** — key by `custom_id`, never by position.\n\n**Models API (no beta; availability: `shared/platform-availability.md`):** `client.models.list()` (auto-paginates) and `client.models.retrieve(\"claude-opus-4-8\")`. Each model object has `id`, `display_name`, `created_at`, and — since Mar 2026 — `max_input_tokens` (the context window), `max_tokens` (the output cap), and `capabilities`. There is no `context_window` field.\n\n**Stop details (GA, Opus 4.7+):** `response.stop_details` is populated **only when `stop_reason == \"refusal\"`** (fields: `type: \"refusal\"`, `category: \"cyber\"|\"bio\"|null`, `explanation`). It is `null` for every other `stop_reason` (`end_turn`, `max_tokens`, `tool_use`, `pause_turn`, …) — always guard before reading.\n\n**Client config (no beta):** `timeout` default 10 min; **units differ by SDK** — Python/Ruby: seconds; TypeScript: **milliseconds**; Go `option.WithRequestTimeout(time.Duration)`; Java `Duration`; C# `TimeSpan`. TS scales the default up to 60 min for large `max_tokens` on non-streaming requests; Java does so for streaming requests (Java non-streaming scales 30s–10 min). `max_retries`/`maxRetries` default 2 (retries 408/409/429/5xx + connection errors). `base_url` (or `ANTHROPIC_BASE_URL` env). Per-request override: Python `client.with_options(timeout=5.0).messages.create(...)`; TS `client.messages.create({...}, {timeout: 5_000})`; Ruby `request_options: {timeout: 5}`. Timeouts are retried — wall-clock can reach `timeout × (max_retries+1)`.\n\n## Workload Identity Federation (Quick Reference)\n\n**GA, no beta header.** Construct the normal zero-arg client (`Anthropic()` / `new Anthropic()` / `anthropic.NewClient()` / `AnthropicOkHttpClient.fromEnv()`); the SDK auto-detects WIF when **all** of `ANTHROPIC_FEDERATION_RULE_ID`, `ANTHROPIC_ORGANIZATION_ID`, `ANTHROPIC_SERVICE_ACCOUNT_ID`, and `ANTHROPIC_IDENTITY_TOKEN_FILE` (or `ANTHROPIC_IDENTITY_TOKEN`) are set, exchanges the JWT at `/v1/oauth/token`, and auto-refreshes. `ANTHROPIC_WORKSPACE_ID` does not gate activation — required only when the federation rule spans multiple workspaces (else 400 `workspace_id_required`), optional for single-workspace rules. `ANTHROPIC_API_KEY` or `ANTHROPIC_AUTH_TOKEN` (even empty) outrank WIF, and a set `ANTHROPIC_PROFILE` also wins over the federation env vars (a missing named profile is an error, not a fall-through) — unset all three.\n\n---\n\n## Reference Documentation\n\nThe relevant documentation for your detected language is included below in `<doc>` tags.

Tool use is supported via the Messages API with a beta `BetaToolRunner` for automatic tool execution loops. The SDK also supports Microsoft.Extensions.AI IChatClient integration with function invocation and Managed Agents (beta).\n\n## Namespace Reference\n\nTypes are organized by namespace. If a type you need isn't shown in an example below, locate it via this table first — don't block on fetching SDK source over the network.\n\n| `using` | Contains |\n|---|---|\n| `Anthropic` | `AnthropicClient`, top-level options |\n| `Anthropic.Models.Messages` | non-beta request/response types — `MessageCreateParams`, `Model`, `Role`, `ContentBlock`, `TextBlock`, `ToolUseBlock`, `ToolResultBlockParam`, `Tool*` (tool definition classes) |\n| `Anthropic.Models.Beta.Messages` | beta-endpoint equivalents — `MessageCreateParams`, `BetaMessage`, `BetaTool*`, `Speed`, `BetaRequestMcpServerUrlDefinition`, context-editing/compaction configs |\n| `Anthropic.Models.Beta` | shared beta constants |\n| `Anthropic.Models.Beta.Files` | Files API types |\n| `Anthropic.Models.Messages.Batches` | Batch API types |\n| `Anthropic.Helpers.Beta` | `BetaToolRunner`, beta helper utilities |\n| `Anthropic.Exceptions` | `AnthropicApiException`, `AnthropicRateLimitException`, `Anthropic5xxException`, etc. — see `shared/error-codes.md` |\n| `Anthropic.Bedrock` / `Anthropic.Vertex` / `Anthropic.Foundry` / `Anthropic.Aws` | platform clients (separate NuGet packages): `AnthropicBedrockMantleClient`, `AnthropicFoundryClient`, `AnthropicAwsClient` |\n\n`client.Messages.*` uses non-beta types; `client.Beta.Messages.*` uses the `Anthropic.Models.Beta.Messages` types. Both namespaces define a `MessageCreateParams` — pick the one matching the client path you call.\n\n### Key types per feature\n\nWrite from this table instead of reflecting the SDK assembly. Endpoint column tells you whether to use `client.Messages.*` or `client.Beta.Messages.*`.\n\n| Feature | Endpoint | Key C# types (namespace per table above) |\n|---|---|---|\n| User profiles | beta | `client.Beta.UserProfiles.Create(...)` / `.Retrieve(id)` / `.List()`. Pass the returned profile id on the beta messages call. Requires a beta header — check the SDK's beta-headers reference for the current flag. |\n| Agent Skills | beta | `BetaContainerParams` (with `Skills = [new BetaSkillParams { ... }]`), `BetaCodeExecutionTool20250825`. `Betas = [\"code-execution-2025-08-25\", \"skills-2025-10-02\"]`. Download the output via `client.Beta.Files.Download(fileId)`. |\n| Advisor tool | beta | `BetaAdvisorTool20260301` — may not be in all SDK releases yet |\n| Cache diagnostics | beta | `Diagnostics = new() { PreviousMessageID = … }`, `BetaCacheControlEphemeral`, `BetaContentBlockParam` |\n| Context editing | beta | `ContextManagement = new BetaContextManagementConfig { Edits = [new BetaClearToolUses20250919Edit()] }`. `Betas = [\"context-management-2025-06-27\"]` (not `compact-2026-01-12` — that's for `BetaCompact20260112Edit`). |\n| Memory tool | non-beta | `Tools = [new ToolUnion(new MemoryTool20250818())]` |\n| Programmatic tool calling | non-beta | `CodeExecutionTool20260120`, `ToolResultBlockParam`, `ContentBlockParam` |\n| Task budgets | beta | `BetaOutputConfig` with `TaskBudget = new BetaTokenTaskBudget { ... }` |\n| Tool search | non-beta | `new ToolUnion(new ToolSearchToolRegex20251119 { Type = ToolSearchToolRegex20251119Type.ToolSearchToolRegex20251119 })` — `Type` must be set explicitly. |\n| Web search | non-beta | `new ToolUnion(new WebSearchTool20260209())` — the latest variant with dynamic filtering (Opus 4.8/4.7/4.6 + Sonnet 4.6). For older models or Vertex, use `WebSearchTool20250305()` |\n\n### Discovering type and member names\n\nIf a type or member you need isn't in the tables above, `strings ~/.nuget/packages/anthropic/*/lib/*/Anthropic.dll | grep -i <term>` is fast and sufficient for locating class and property names. **Do not escalate to a `dotnet run` reflection probe** to dump members precisely — the first compile is slow enough to be backgrounded in many environments, trapping you in a polling loop. Instead, write `Program.cs` using the names `strings | grep` found; if a member name is wrong the compiler error (`error CS1061: 'X' does not contain a definition for 'Y'`) points at it in a few seconds, faster than any reflection probe.\n\nNote that `strings` will not surface wire-format snake_case field names (`output_tokens`, `stop_reason`) — those are stored in the DLL differently. **C# properties are the PascalCase equivalent of the wire field** (`response.Usage.OutputTokens`, `response.StopReason`). If you know the wire field name from the docs, write the PascalCase property and compile; do not probe for the snake_case string.\n\n### Minimal working skeleton\n\n**Write a plain `Program.cs` body** — `using` statements followed by top-level statements, as below. Do **not** add a `#!/usr/bin/env dotnet` shebang or `#:package Anthropic@*` directive: those are .NET file-based-app syntax and fail with `CS1024: Preprocessor directive expected` when the file is compiled via an existing `.csproj`. The standard project setup (per the [C# quickstart](https://docs.claude.com/en/docs/get-started): `dotnet new console` → `dotnet add package Anthropic` → edit `Program.cs` → `dotnet run`) provides the `.csproj` and package reference.\n\nStart from this — it compiles as-is. Fill in the feature-specific fields; do not spend turns running reflection or XML-doc inspection to discover type names first.\n\n```csharp\nusing System;\nusing Anthropic;\nusing Anthropic.Models.Messages; // or Anthropic.Models.Beta.Messages for beta endpoints\n\nAnthropicClient client = new();\n\nvar message = await client.Messages.Create(new MessageCreateParams\n{\n Model = Model.ClaudeOpus4_8,\n MaxTokens = 1024,\n Messages = [ new() { Role = Role.User, Content = \"Hello, Claude\" } ],\n});\n\nConsole.WriteLine(message);\n```\n\nFor beta features (anything behind an `anthropic-beta` header), use the beta client path and namespace — same overall shape:\n\n```csharp\nusing System;\nusing Anthropic;\nusing Anthropic.Models.Beta.Messages;\n\nAnthropicClient client = new();\n\nvar response = await client.Beta.Messages.Create(new MessageCreateParams\n{\n Model = \"claude-opus-4-8\",\n MaxTokens = 4096,\n Betas = [\"<beta-flag>\"],\n Messages = [ new() { Role = Role.User, Content = \"…\" } ],\n // Tools = new BetaToolUnion[] { new BetaSomeTool { … } }, // for tool features\n});\n\nConsole.WriteLine(response);\n```\n\nIf a type name the feature needs isn't in this file, write it following the naming pattern in the Namespace Reference above and fix from compiler output — producing a `Program.cs` and iterating beats researching.\n\n### Common C# compile errors\n\n- **CS8803 (top-level statements must precede type declarations):** put any `record`/`class`/`struct` definitions **after** the last top-level statement, at the end of the file. A record defined above `var client = new AnthropicClient()` will not compile.\n- **`await foreach` on a `Task<…Page>`:** `client.Models.List()` returns a `Task<ModelListPage>`, which is not directly async-enumerable. Await it first, then iterate: `var page = await client.Models.List(); foreach (var m in page.Items) {…}`. For auto-pagination, check whether the page type exposes `AutoPagingEachAsync()` or similar before reaching for `await foreach`.\n\n## Installation\n\n```bash\ndotnet add package Anthropic\n```\n\n## Client Initialization\n\n```csharp\nusing Anthropic;\n\n// Default (uses ANTHROPIC_API_KEY env var)\nAnthropicClient client = new();\n\n// Explicit API key (use environment variables — never hardcode keys)\nAnthropicClient client = new() {\n ApiKey = Environment.GetEnvironmentVariable(\"ANTHROPIC_API_KEY\")\n};\n```\n\n---\n\n## Basic Message Request\n\n```csharp\nusing Anthropic.Models.Messages;\n\nvar parameters = new MessageCreateParams\n{\n Model = Model.ClaudeOpus4_8,\n MaxTokens = 16000,\n Messages = [new() { Role = Role.User, Content = \"What is the capital of France?\" }]\n};\nvar response = await client.Messages.Create(parameters);\n\n// ContentBlock is a union wrapper. .Value unwraps to the variant object,\n// then OfType<T> filters to the type you want. Or use the TryPick* idiom\n// shown in the Thinking section below.\nforeach (var text in response.Content.Select(b => b.Value).OfType<TextBlock>())\n{\n Console.WriteLine(text.Text);\n}\n```\n\n---\n\n## Thinking\n\n**Adaptive thinking is the recommended mode for Claude 4.6+ models.** Claude decides dynamically when and how much to think.\n\n> **Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6:** Use adaptive thinking (below). `new ThinkingConfigEnabled { BudgetTokens = N }` is removed on Fable 5, Opus 4.8, and 4.7 (400 if sent); deprecated on Opus 4.6 and Sonnet 4.6.\n> **Older models:** Use `new ThinkingConfigEnabled { BudgetTokens = N }` (budget must be < `MaxTokens`, min 1024).\n\n```csharp\nusing Anthropic.Models.Messages;\n\nvar response = await client.Messages.Create(new MessageCreateParams\n{\n Model = Model.ClaudeOpus4_8,\n MaxTokens = 16000,\n // ThinkingConfigParam? implicitly converts from the concrete variant classes —\n // no wrapper needed.\n // display opt-in: default is omitted (empty thinking text) on Fable 5 / Mythos 5 / Opus 4.8 / 4.7\n Thinking = new ThinkingConfigAdaptive { Display = Display.Summarized },\n Messages =\n [\n new() { Role = Role.User, Content = \"Solve: 27 * 453\" },\n ],\n});\n\n// ThinkingBlock(s) precede TextBlock in Content. TryPick* narrows the union.\nforeach (var block in response.Content)\n{\n if (block.TryPickThinking(out ThinkingBlock? t))\n {\n Console.WriteLine($\"[thinking] {t.Thinking}\");\n }\n else if (block.TryPickText(out TextBlock? text))\n {\n Console.WriteLine(text.Text);\n }\n}\n```\n\nAlternative to `TryPick*`: `.Select(b => b.Value).OfType<ThinkingBlock>()` (same LINQ pattern as the Basic Message example).\n\n---\n\n## Context Editing / Compaction (Beta)\n\n**Beta-namespace prefix is inconsistent** (source-verified against `src/Anthropic/Models/Beta/Messages/*.cs` @ 12.9.0). No prefix: `MessageCreateParams`, `MessageCountTokensParams`, `Role`, `Speed`. **Everything else has the `Beta` prefix**: `BetaMessageParam`, `BetaMessage`, `BetaContentBlock`, `BetaToolUseBlock`, all block param types. The unprefixed `Role` WILL collide with `Anthropic.Models.Messages.Role` if you import both namespaces (CS0104). Safest: import only Beta; if mixing, alias the beta `Role`:\n\n```csharp\nusing Anthropic.Models.Beta.Messages;\nusing NonBeta = Anthropic.Models.Messages; // only if you also need non-beta types\n// Now: MessageCreateParams, BetaMessageParam, Role (beta's), NonBeta.Role (if needed)\n```\n\n\n`BetaMessage.Content` is `IReadOnlyList<BetaContentBlock>` — a 15-variant discriminated union. Narrow with `TryPick*`. **Response `BetaContentBlock` is NOT assignable to param `BetaContentBlockParam`** — there's no `.ToParam()` in C#. Round-trip by converting each block:\n\n```csharp\nusing Anthropic.Models.Beta.Messages;\n\nvar betaParams = new MessageCreateParams // no Beta prefix — see unprefixed list above\n{\n Model = Model.ClaudeOpus4_8,\n MaxTokens = 16000,\n Betas = [\"compact-2026-01-12\"],\n ContextManagement = new BetaContextManagementConfig\n {\n Edits = [new BetaCompact20260112Edit()],\n },\n Messages = messages,\n};\nBetaMessage resp = await client.Beta.Messages.Create(betaParams);\n\nforeach (BetaContentBlock block in resp.Content)\n{\n if (block.TryPickCompaction(out BetaCompactionBlock? compaction))\n {\n // Content is nullable — compaction can fail server-side\n Console.WriteLine($\"compaction summary: {compaction.Content}\");\n }\n}\n\n// Context-edit metadata lives on a separate nullable field\nif (resp.ContextManagement is { } ctx)\n{\n foreach (var edit in ctx.AppliedEdits)\n Console.WriteLine($\"cleared {edit.ClearedInputTokens} tokens\");\n}\n\n// ROUND-TRIP: BetaMessageParam.Content is BetaMessageParamContent (a string|list\n// union). It implicit-converts from List<BetaContentBlockParam>, NOT from the\n// response's IReadOnlyList<BetaContentBlock>. Convert each block:\nList<BetaContentBlockParam> paramBlocks = [];\nforeach (var b in resp.Content)\n{\n if (b.TryPickText(out var t)) paramBlocks.Add(new BetaTextBlockParam { Text = t.Text });\n else if (b.TryPickCompaction(out var c)) paramBlocks.Add(new BetaCompactionBlockParam { Content = c.Content });\n // ... other variants as needed\n}\nmessages.Add(new BetaMessageParam { Role = Role.Assistant, Content = paramBlocks });\n```\n\nAll 15 `BetaContentBlock.TryPick*` variants: `Text`, `Thinking`, `RedactedThinking`, `ToolUse`, `ServerToolUse`, `WebSearchToolResult`, `WebFetchToolResult`, `CodeExecutionToolResult`, `BashCodeExecutionToolResult`, `TextEditorCodeExecutionToolResult`, `ToolSearchToolResult`, `McpToolUse`, `McpToolResult`, `ContainerUpload`, `Compaction`.\n\n**`BetaToolUseBlock.Input` is `IReadOnlyDictionary<string, JsonElement>`** — index by key then call the `JsonElement` extractor:\n\n```csharp\nif (block.TryPickToolUse(out BetaToolUseBlock? tu))\n{\n int a = tu.Input[\"a\"].GetInt32();\n string s = tu.Input[\"name\"].GetString()!;\n}\n```\n\n---\n\n## Effort Parameter\n\nEffort is nested under `OutputConfig`, NOT a top-level property. `ApiEnum<string, Effort>` has an implicit conversion from the enum, so assign `Effort.High` directly.\n\n```csharp\nOutputConfig = new OutputConfig { Effort = Effort.High },\n```\n\nValues: `Effort.Low`, `Effort.Medium`, `Effort.High`, `Effort.Max`. Combine with `Thinking = new ThinkingConfigAdaptive()` for cost-quality control.\n\n---\n\n## Prompt Caching\n\n`System` takes `MessageCreateParamsSystem?` — a union of `string` or `List<TextBlockParam>`. There is no `SystemTextBlockParam`; use plain `TextBlockParam`. The implicit conversion needs the concrete `List<TextBlockParam>` type (array literals won't convert). For placement patterns and the silent-invalidator audit checklist, see `shared/prompt-caching.md`.\n\n```csharp\nSystem = new List<TextBlockParam> {\n new() {\n Text = longSystemPrompt,\n CacheControl = new CacheControlEphemeral(), // auto-sets Type = \"ephemeral\"\n },\n},\n```\n\nOptional `Ttl` on `CacheControlEphemeral`: `new() { Ttl = Ttl.Ttl1h }` or `Ttl.Ttl5m`. `CacheControl` also exists on `Tool.CacheControl` and top-level `MessageCreateParams.CacheControl`.\n\nVerify hits via `response.Usage.CacheCreationInputTokens` / `response.Usage.CacheReadInputTokens`.\n\n---\n\n## Token Counting\n\n```csharp\nMessageTokensCount result = await client.Messages.CountTokens(new MessageCountTokensParams {\n Model = Model.ClaudeOpus4_8,\n Messages = [new() { Role = Role.User, Content = \"Hello\" }],\n});\nlong tokens = result.InputTokens;\n```\n\n`MessageCountTokensParams.Tools` uses a different union type (`MessageCountTokensTool`) than `MessageCreateParams.Tools` (`ToolUnion`) — if you're passing tools, the compiler will tell you when it matters.\n\n---\n\n## PDF / Document Input\n\n`DocumentBlockParam` takes a `DocumentBlockParamSource` union: `Base64PdfSource` / `UrlPdfSource` / `PlainTextSource` / `ContentBlockSource`. `Base64PdfSource` auto-sets `MediaType = \"application/pdf\"` and `Type = \"base64\"`.\n\n```csharp\nnew MessageParam {\n Role = Role.User,\n Content = new List<ContentBlockParam> {\n new DocumentBlockParam { Source = new Base64PdfSource { Data = base64String } },\n new TextBlockParam { Text = \"Summarize this PDF\" },\n },\n}\n```\n\n---\n\n## Fast Mode (Beta)\n\n```csharp\nvar response = await client.Beta.Messages.Create(new MessageCreateParams {\n Model = \"claude-opus-4-8\", MaxTokens = 4096,\n Speed = Speed.Fast,\n Betas = [\"fast-mode-2026-02-01\"],\n Messages = [...],\n});\n```\n\n## Models API\n\n```csharp\nvar page = await client.Models.List();\nforeach (var m in page.Items) { Console.WriteLine(m.ID); }\nvar one = await client.Models.Retrieve(\"claude-opus-4-8\");\n```\n\n## Long Output (128k) + Prefill\n\nSet `MaxTokens = 128000` on `client.Messages` and use the streaming path (see `streaming.md`). On Claude 4+ models, 128k output is native — no `output-128k-*` beta header or beta namespace is needed.\n\n**Prefilling the assistant message** (putting a trailing `Role.Assistant` message in the input) is **not supported** on Claude Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6 — requests return a 400. Use `OutputConfig.Format` (structured outputs) instead.\n\n## Stop Details\n\nWhen `StopReason` is `\"refusal\"`, the response includes structured `StopDetails`:\n\n```csharp\nif (response.StopReason == \"refusal\" && response.StopDetails is { } details)\n{\n Console.WriteLine($\"Category: {details.Category}\");\n Console.WriteLine($\"Explanation: {details.Explanation}\");\n}\n```\n\n**Refusal fallbacks (Claude Fable 5) — opt in by default.** Fallbacks are opt-in: without them a refused request simply stops. In `claude-fable-5` code, include `Fallbacks = [new(Model.ClaudeOpus4_8)]` plus the `AnthropicBeta.ServerSideFallback2026_06_01` beta on the beta messages call by default — a policy decline is re-served by the fallback model inside the same call. Not available on Amazon Bedrock, Vertex AI, or Microsoft Foundry — use the client-side handler there: `new AnthropicClient { Handlers = [new BetaRefusalFallbackHandler { Fallbacks = [new(Model.ClaudeOpus4_8)] }] }` (namespace `Anthropic.Helpers`), with per-conversation state via `BetaFallbackState.Create()` scoped with `using (fallbackState.Use()) { ... }`. Full semantics (billing, sticky routing, streaming) and a runnable example: `shared/model-migration.md` → Migrating to Claude Fable 5 → `refusal` stop reason, and the C# SDK repo's `examples/` (WebFetch via `shared/live-sources.md`).\n\n---\n\n## Managed Agents (Beta)\n\nThe C# SDK supports Managed Agents via `client.Beta.Agents`, `client.Beta.Sessions`, `client.Beta.Environments`, and related namespaces. See `shared/managed-agents-overview.md` for the architecture and `curl/managed-agents.md` for the wire-level reference.\n</doc>\n\n<doc path=\"csharp/claude-api/batches.md\">\n# Message Batches — C#\n\n## Message Batches API\n\n```csharp\nvar batch = await client.Messages.Batches.Create(new() {\n Requests = [\n new() { CustomID = \"req-1\", Params = new() { Model = \"claude-opus-4-8\", MaxTokens = 1024, Messages = [...] } },\n ],\n});\n// Poll client.Messages.Batches.Retrieve(batch.ID) until ProcessingStatus == \"ended\",\n// then iterate client.Messages.Batches.Results(batch.ID).\n```\n</doc>\n\n<doc path=\"csharp/claude-api/files-api.md\">\n# Files API — C#\n\n## Files API (Beta)\n\nFiles live under `client.Beta.Files` (namespace `Anthropic.Models.Beta.Files`). `BinaryContent` implicit-converts from `Stream` and `byte[]`.\n\n```csharp\nusing Anthropic.Models.Beta.Files;\nusing Anthropic.Models.Beta.Messages;\n\nFileMetadata meta = await client.Beta.Files.Upload(\n new FileUploadParams { File = File.OpenRead(\"doc.pdf\") });\n\n// Referencing the uploaded file requires Beta message types:\nnew BetaRequestDocumentBlock {\n Source = new BetaFileDocumentSource { FileID = meta.ID },\n}\n```\n\nThe non-beta `DocumentBlockParamSource` union has no file-ID variant — file references need `client.Beta.Messages.Create()`.\n\n---\n</doc>\n\n<doc path=\"csharp/claude-api/streaming.md\">\n# Streaming — C#\n\n## Streaming\n\n```csharp\nusing Anthropic.Models.Messages;\n\nvar parameters = new MessageCreateParams\n{\n Model = Model.ClaudeOpus4_8,\n MaxTokens = 64000,\n Messages = [new() { Role = Role.User, Content = \"Write a haiku\" }]\n};\n\nawait foreach (RawMessageStreamEvent streamEvent in client.Messages.CreateStreaming(parameters))\n{\n if (streamEvent.TryPickContentBlockDelta(out var delta) &&\n delta.Delta.TryPickText(out var text))\n {\n Console.Write(text.Text);\n }\n}\n```\n\n**`RawMessageStreamEvent` TryPick methods** (naming drops the `Message`/`Raw` prefix): `TryPickStart`, `TryPickDelta`, `TryPickStop`, `TryPickContentBlockStart`, `TryPickContentBlockDelta`, `TryPickContentBlockStop`. There is no `TryPickMessageStop` — use `TryPickStop`.\n\n---\n</doc>\n\n<doc path=\"csharp/claude-api/tool-use.md\">\n# Tool Use — C#\n\nFor conceptual overview (tool definitions, tool choice, tips), see [shared/tool-use-concepts.md](../../shared/tool-use-concepts.md).\n\n## Tool Use\n\n### Defining a tool\n\n`Tool` (NOT `ToolParam`) with an `InputSchema` record. `InputSchema.Type` is auto-set to `\"object\"` by the constructor — don't set it. `ToolUnion` has an implicit conversion from `Tool`, triggered by the collection expression `[...]`.\n\n```csharp\nusing System.Text.Json;\nusing Anthropic.Models.Messages;\n\nvar parameters = new MessageCreateParams\n{\n Model = Model.ClaudeSonnet4_6,\n MaxTokens = 16000,\n Tools = [\n new Tool {\n Name = \"get_weather\",\n Description = \"Get the current weather in a given location\",\n InputSchema = new() {\n Properties = new Dictionary<string, JsonElement> {\n [\"location\"] = JsonSerializer.SerializeToElement(\n new { type = \"string\", description = \"City name\" }),\n },\n Required = [\"location\"],\n },\n },\n ],\n Messages = [new() { Role = Role.User, Content = \"Weather in Paris?\" }],\n};\n```\n\nDerived from `anthropic-sdk-csharp/src/Anthropic/Models/Messages/Tool.cs` and `ToolUnion.cs:799` (implicit conversion).\n\nSee [shared tool use concepts](../../shared/tool-use-concepts.md) for the loop pattern.\n### Converting response content to the follow-up assistant message\n\nWhen echoing Claude's response back in the assistant turn, **there is no `.ToParam()` helper** — manually reconstruct each `ContentBlock` variant as its `*Param` counterpart. Do NOT use `new ContentBlockParam(block.Json)`: it compiles and serializes, but `.Value` stays `null` so `TryPick*`/`Validate()` fail (degraded JSON pass-through, not the typed path).\n\n```csharp\nusing Anthropic.Models.Messages;\n\nMessage response = await client.Messages.Create(parameters);\n\n// No .ToParam() — reconstruct per variant.

Web search and code execution are server-executed; bash and text editor are client-executed (you handle the `tool_use` locally — see `shared/tool-use-concepts.md`). Type names are version-suffixed; constructors auto-set `name`/`type`. **Wrap each in `new ToolUnion(...)` explicitly.**\n\n```csharp\nTools = [\n new ToolUnion(new WebSearchTool20260209()),\n new ToolUnion(new ToolBash20250124()),\n new ToolUnion(new ToolTextEditor20250728()),\n new ToolUnion(new CodeExecutionTool20260120()),\n],\n```\n\nAlso available: `new ToolUnion(new WebFetchTool20260209())`, `new ToolUnion(new MemoryTool20250818())`. `WebSearchTool20260209` optionals: `AllowedDomains`, `BlockedDomains`, `MaxUses`, `UserLocation`.\n\n---\n\n## Tool Runner (Beta)\n\nThe C# SDK provides a `BetaToolRunner` for automatic tool execution loops. Define tools with raw JSON schemas, and the runner handles the API call → tool execution → result feedback loop.\n\n```csharp\nusing Anthropic.Models.Beta.Messages;\n\n// Define tools and create params as shown in the Tool Use section above,\n// but using the beta namespace types (BetaToolUnion, etc.)\nvar runner = client.Beta.Messages.ToolRunner(betaParams);\n\nawait foreach (BetaMessage message in runner)\n{\n foreach (var block in message.Content)\n {\n if (block.TryPickText(out var text))\n {\n Console.WriteLine(text.Text);\n }\n }\n}\n```\n\n---\n</doc>\n\n<doc path=\"curl/examples.md\">\n# Claude API — cURL / Raw HTTP\n\nUse these examples when the user needs raw HTTP requests or is working in a language without an official SDK.\n\n## Setup\n\n```bash\nexport ANTHROPIC_API_KEY=\"your-api-key\"\n```\n\n---\n\n## Basic Message Request\n\n```bash\ncurl https://api.anthropic.com/v1/messages \\\n -H \"Content-Type: application/json\" \\\n -H \"x-api-key: $ANTHROPIC_API_KEY\" \\\n -H \"anthropic-version: 2023-06-01\" \\\n -d '{\n \"model\": \"claude-opus-4-8\",\n \"max_tokens\": 16000,\n \"messages\": [\n {\"role\": \"user\", \"content\": \"What is the capital of France?\"}\n ]\n }'\n```\n\n### Parsing the response\n\nUse `jq` to extract fields from the JSON response.

Fallbacks are **opt-in**: without them the request simply stops. Include the `fallbacks` parameter and its beta header by default — on a policy decline the API re-runs the same request on the fallback model inside the same call. A decline before any output isn't billed (a mid-stream decline bills the streamed partial); the rescue bills at the fallback model's own rates.\n\n```bash\nresponse=$(curl -s https://api.anthropic.com/v1/messages \\\n -H \"Content-Type: application/json\" \\\n -H \"x-api-key: $ANTHROPIC_API_KEY\" \\\n -H \"anthropic-version: 2023-06-01\" \\\n -H \"anthropic-beta: server-side-fallback-2026-06-01\" \\\n -d '{\n \"model\": \"claude-fable-5\",\n \"max_tokens\": 16000,\n \"fallbacks\": [{\"model\": \"claude-opus-4-8\"}],\n \"messages\": [{\"role\": \"user\", \"content\": \"Hello\"}]\n }')\n\n# Which model produced the message\necho \"$response\" | jq -r '.model'\n\n# Refusal on the final response means the whole chain refused\necho \"$response\" | jq -r '.stop_reason'\n\n# Switch points: one fallback block per model that ran and declined this turn\necho \"$response\" | jq -r '.content[] | select(.type == \"fallback\") | \"\\(.from.model) declined; \\(.to.model) continued\"'\n\n# Served-by signal — covers sticky turns, which carry no fallback block.\n# Pair with stop_reason: the fallback model can itself refuse.\nif [ \"$(echo \"$response\" | jq -r '.stop_reason')\" != \"refusal\" ] && \\\n echo \"$response\" | jq -e '[.usage.iterations[]? | select(.type == \"fallback_message\")] | length > 0' > /dev/null; then\n echo \"fallback model served this turn\"\nfi\n```\n\nThe header must be exactly `server-side-fallback-2026-06-01`.

The response will contain `ThinkingBlock` content before the final `TextBlock`.\n\n**Adaptive thinking is the recommended mode for Claude 4.6+ models.** Claude decides dynamically when and how much to think. Combine with the `effort` parameter for cost-quality control.\n\nDerived from `anthropic-sdk-go/message.go` (`ThinkingConfigParamUnion`, `ThinkingConfigAdaptiveParam`).\n\n```go\n// There is no ThinkingConfigParamOfAdaptive helper — construct the union\n// struct-literal directly and take the address of the variant.\nadaptive := anthropic.ThinkingConfigAdaptiveParam{}\nparams := anthropic.MessageNewParams{\n Model: anthropic.ModelClaudeSonnet4_6,\n MaxTokens: 16000,\n Thinking: anthropic.ThinkingConfigParamUnion{OfAdaptive: &adaptive},\n Messages: []anthropic.MessageParam{\n anthropic.NewUserMessage(anthropic.NewTextBlock(\"How many r's in strawberry?\")),\n },\n}\n\nresp, err := client.Messages.New(context.Background(), params)\nif err != nil {\n log.Fatal(err)\n}\n\n// ThinkingBlock(s) precede TextBlock in content\nfor _, block := range resp.Content {\n switch b := block.AsAny().(type) {\n case anthropic.ThinkingBlock:\n fmt.Println(\"[thinking]\", b.Thinking)\n case anthropic.TextBlock:\n fmt.Println(b.Text)\n }\n}\n```\n\n> **Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6:** Use adaptive thinking (above). `ThinkingConfigParamOfEnabled(budgetTokens)` is removed on Fable 5, Opus 4.8, and 4.7 (400 if sent); deprecated on Opus 4.6 and Sonnet 4.6.\n> **Older models:** Use `anthropic.ThinkingConfigParamOfEnabled(N)` (budget must be < `MaxTokens`, min 1024).\n\nTo disable: `anthropic.ThinkingConfigParamUnion{OfDisabled: &anthropic.ThinkingConfigDisabledParam{}}`.\n\n---\n\n## Prompt Caching\n\n`System` is `[]TextBlockParam`; set `CacheControl` on the last block to cache tools + system together. For placement patterns and the silent-invalidator audit checklist, see `shared/prompt-caching.md`.\n\n```go\nSystem: []anthropic.TextBlockParam{{\n Text: longSystemPrompt,\n CacheControl: anthropic.NewCacheControlEphemeralParam(), // default 5m TTL\n}},\n```\n\nFor 1-hour TTL: `anthropic.CacheControlEphemeralParam{TTL: anthropic.CacheControlEphemeralTTLTTL1h}`. There's also a top-level `CacheControl` on `MessageNewParams` that auto-places on the last cacheable block.\n\nVerify hits via `resp.Usage.CacheCreationInputTokens` / `resp.Usage.CacheReadInputTokens`.\n\n---\n\n## Stop Details\n\nWhen `StopReason` is `anthropic.StopReasonRefusal`, the response includes structured `StopDetails`:\n\n```go\nif resp.StopReason == anthropic.StopReasonRefusal {\n fmt.Println(\"Category:\", resp.StopDetails.Category) // e.g. \"cyber\", \"bio\", \"reasoning_extraction\", \"frontier_llm\", or \"\" — see docs for the full set\n fmt.Println(\"Explanation:\", resp.StopDetails.Explanation)\n}\n```\n\n**Refusal fallbacks (Claude Fable 5) — opt in by default.** Fallbacks are opt-in: without them a refused request simply stops. In `claude-fable-5` code, include `Fallbacks: []anthropic.BetaFallbackParam{{Model: \"claude-opus-4-8\"}}` plus the `anthropic.AnthropicBetaServerSideFallback2026_06_01` beta on `client.Beta.Messages.New` by default — a policy decline is re-served by the fallback model inside the same call. Not available on Amazon Bedrock, Vertex AI, or Microsoft Foundry — register the client-side middleware there: `option.WithMiddleware(betafallback.BetaRefusalFallbackMiddleware(...))` from `lib/betafallback`, with per-conversation state via `betafallback.WithBetaFallbackState(&betafallback.BetaFallbackState{})`. Full semantics (billing, sticky routing, streaming) and a runnable example: `shared/model-migration.md` → Migrating to Claude Fable 5 → `refusal` stop reason, and the Go SDK repo's `examples/` (WebFetch via `shared/live-sources.md`).\n\n---\n\n## PDF / Document Input\n\n`NewDocumentBlock` generic helper accepts any source type. `MediaType`/`Type` are auto-set.\n\n```go\nb64 := base64.StdEncoding.EncodeToString(pdfBytes)\n\nmsg := anthropic.NewUserMessage(\n anthropic.NewDocumentBlock(anthropic.Base64PDFSourceParam{Data: b64}),\n anthropic.NewTextBlock(\"Summarize this document\"),\n)\n```\n\nOther sources: `URLPDFSourceParam{URL: \"https://...\"}`, `PlainTextSourceParam{Data: \"...\"}`.\n\n---\n\n## Context Editing / Compaction (Beta)\n\nUse `Beta.Messages.New` with `ContextManagement` on `BetaMessageNewParams`. There is no `NewBetaAssistantMessage` — use `.ToParam()` for the round-trip.\n\n```go\nparams := anthropic.BetaMessageNewParams{\n Model: anthropic.ModelClaudeOpus4_8, // also supported: ModelClaudeSonnet4_6\n MaxTokens: 16000,\n Betas: []anthropic.AnthropicBeta{\"compact-2026-01-12\"},\n ContextManagement: anthropic.BetaContextManagementConfigParam{\n Edits: []anthropic.BetaContextManagementConfigEditUnionParam{\n {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{}},\n },\n },\n Messages: []anthropic.BetaMessageParam{ /* ... */ },\n}\n\nresp, err := client.Beta.Messages.New(ctx, params)\nif err != nil {\n log.Fatal(err)\n}\n\n// Round-trip: append response to history via .ToParam()\nparams.Messages = append(params.Messages, resp.ToParam())\n\n// Read compaction blocks from the response\nfor _, block := range resp.Content {\n if c, ok := block.AsAny().(anthropic.BetaCompactionBlock); ok {\n fmt.Println(\"compaction summary:\", c.Content)\n }\n}\n```\n\nOther edit types: `BetaClearToolUses20250919EditParam`, `BetaClearThinking20251015EditParam` — these need `Betas: []anthropic.AnthropicBeta{\"context-management-2025-06-27\"}`, not `compact-2026-01-12`.\n</doc>\n\n<doc path=\"go/claude-api/files-api.md\">\n# Files API — Go\n\n## Files API (Beta)\n\nUnder `client.Beta.Files`.

If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the Go SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.\n\n> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.New` and pass it to every subsequent `sessions.New`; do not call `agents.New` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.\n\n## Installation\n\n```bash\ngo get github.com/anthropics/anthropic-sdk-go\n```\n\n## Client Initialization\n\n```go\nimport (\n \"context\"\n\n \"github.com/anthropics/anthropic-sdk-go\"\n \"github.com/anthropics/anthropic-sdk-go/option\"\n)\n\n// Default (uses ANTHROPIC_API_KEY env var)\nclient := anthropic.NewClient()\n\n// Explicit API key\nclient := anthropic.NewClient(\n option.WithAPIKey(\"your-api-key\"),\n)\n\nctx := context.Background()\n```\n\n---\n\n## Create an Environment\n\n```go\nenvironment, err := client.Beta.Environments.New(ctx, anthropic.BetaEnvironmentNewParams{\n Name: \"my-dev-env\",\n Config: anthropic.BetaEnvironmentNewParamsConfigUnion{\n OfCloud: &anthropic.BetaCloudConfigParams{\n Networking: anthropic.BetaCloudConfigParamsNetworkingUnion{\n OfUnrestricted: &anthropic.BetaUnrestrictedNetworkParam{},\n },\n },\n },\n})\nif err != nil {\n panic(err)\n}\nfmt.Println(environment.ID) // env_...\n```\n\n---\n\n## Create an Agent (required first step)\n\n> ⚠️ **There is no inline agent config.** `Model`/`System`/`Tools` live on the agent object, not the session.

path=\"java/claude-api/README.md\">\n# Claude API — Java\n\n> **Note:** The Java SDK supports the Claude API and beta tool use with annotated classes. Agent SDK is not yet available for Java.\n\n## Package Reference\n\nTypes are organized by package. If a class you need isn't shown in an example below, locate it via this table first — don't block on fetching SDK source over the network.\n\n| `import` prefix | Contains |\n|---|---|\n| `com.anthropic.client` / `com.anthropic.client.okhttp` | `AnthropicClient`, `AnthropicOkHttpClient` |\n| `com.anthropic.models.messages` | non-beta request/response types — `MessageCreateParams`, `Model`, `Message`, `TextBlockParam`, `ContentBlockParam`, `ToolUseBlockParam`, `ToolResultBlockParam`, `CacheControlEphemeral`, `Tool*` (e.g. `ToolBash20250124`, `ToolTextEditor20250728`), `StopReason`, `StructuredMessage*` |\n| `com.anthropic.models.messages.batches` | Batch API — `BatchResultsParams`, `MessageBatchIndividualResponse` |\n| `com.anthropic.models.beta` | `AnthropicBeta` (beta-flag constants) |\n| `com.anthropic.models.beta.messages` | beta-endpoint types — `MessageCreateParams`, `BetaMessage`, `BetaStopReason`, `BetaContextManagementConfig`, `BetaMcpToolset`, `BetaRequestMcpServerUrlDefinition`, `BetaTool*` |\n| `com.anthropic.core` | `JsonValue`, `JsonField`, `JsonSchemaLocalValidation`, `com.anthropic.core.http.StreamResponse` |\n| `com.anthropic.errors` | typed exceptions — `AnthropicServiceException`, `RateLimitException`, `NotFoundException`, etc. (see `shared/error-codes.md`) |\n\n`client.messages()` uses `com.anthropic.models.messages.*`; `client.beta().messages()` uses `com.anthropic.models.beta.messages.*`. Both packages define a `MessageCreateParams` — import the one matching the client path you call.\n\n### Key types per feature\n\nWrite from this table instead of `javap`/jar inspection. Endpoint column tells you whether to use `client.messages()` or `client.beta().messages()`.\n\n| Feature | Endpoint | Key Java types / builder calls |\n|---|---|---|\n| User profiles | beta | `client.beta().userProfiles().create(...)` / `.retrieve(id)` / `.list()`. Pass the returned profile id on the beta `MessageCreateParams`. Requires a beta header — check the SDK's beta-headers reference for the current flag. |\n| Agent Skills | beta | `BetaContainerParams`, `BetaSkillParams`, `BetaCodeExecutionTool20250825`. `.addBeta(\"code-execution-2025-08-25\").addBeta(\"skills-2025-10-02\")`. Download the output via `client.beta().files().download(fileId)`. |\n| Cache diagnostics | beta | `BetaDiagnosticsParam`, `BetaCacheControlEphemeral` |\n| Context editing | beta | `.contextManagement(BetaContextManagementConfig.builder()…)`. The edit strategy is a `BetaClearToolUses20250919Edit` (or `BetaClearThinking20251015Edit`); its trigger is a `BetaInputTokensTrigger` built separately and passed to the edit's builder — there is no direct `.inputTokensTrigger(N)` shortcut on the edit builder. `javap` the edit and trigger classes for the exact setter names. |\n| Memory tool | non-beta | `.addTool(MemoryTool20250818.builder().build())` from `com.anthropic.models.messages` |\n| Programmatic tool calling | non-beta | `CodeExecutionTool20260120`, `Tool`, `ContentBlockParam` |\n| Strict tool use | non-beta | `Tool`, `Tool.InputSchema` |\n| Task budgets | beta | `.outputConfig(BetaOutputConfig.builder().taskBudget(BetaTokenTaskBudget.builder()...))` |\n| Tool search | non-beta | `.addTool(ToolSearchToolRegex20251119.builder()...)` from `com.anthropic.models.messages` |\n| Web search | non-beta | `WebSearchTool20260209` from `com.anthropic.models.messages` — the latest variant with dynamic filtering (Opus 4.8/4.7/4.6 + Sonnet 4.6). For older models or Vertex, use `WebSearchTool20250305` |\n\n### Discovering type and member names\n\nIf a class or builder method you need isn't in the tables above, `jar tf <anthropic-java-core jar> | grep -i <term>` or `javap -classpath <jar> com.anthropic.models.…` is fast enough to locate names. **Do not compile and run a separate reflection program** to enumerate members — the first build is slow enough to be backgrounded in many environments, trapping you in a polling loop. Write the script with the names you found and let the compiler error (`cannot find symbol`) point at any wrong member.\n\n## Installation\n\nMaven:\n\n```xml\n<dependency>\n <groupId>com.anthropic</groupId>\n <artifactId>anthropic-java</artifactId>\n <version>2.34.0</version>\n</dependency>\n```\n\nGradle:\n\n```groovy\nimplementation(\"com.anthropic:anthropic-java:2.34.0\")\n```\n\n## Client Initialization\n\n```java\nimport com.anthropic.client.AnthropicClient;\nimport com.anthropic.client.okhttp.AnthropicOkHttpClient;\n\n// Default (reads ANTHROPIC_API_KEY from environment)\nAnthropicClient client = AnthropicOkHttpClient.fromEnv();\n\n// Explicit API key\nAnthropicClient client = AnthropicOkHttpClient.builder()\n .apiKey(\"your-api-key\")\n .build();\n```\n\n---\n\n## Basic Message Request\n\n```java\nimport com.anthropic.models.messages.MessageCreateParams;\nimport com.anthropic.models.messages.Message;\nimport com.anthropic.models.messages.Model;\n\nMessageCreateParams params = MessageCreateParams.builder()\n .model(Model.CLAUDE_OPUS_4_8)\n .maxTokens(16000L)\n .addUserMessage(\"What is the capital of France?\")\n .build();\n\nMessage response = client.messages().create(params);\nresponse.content().stream()\n .flatMap(block -> block.text().stream())\n .forEach(textBlock -> System.out.println(textBlock.text()));\n```\n\n---\n\n## Thinking\n\n**Adaptive thinking is the recommended mode for Claude 4.6+ models.** Claude decides dynamically when and how much to think. The builder has a direct `.thinking(ThinkingConfigAdaptive)` overload — no manual union wrapping.\n\n> **Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6:** Use adaptive thinking (below). `ThinkingConfigEnabled.builder().budgetTokens(N)` is removed on Fable 5, Opus 4.8, and 4.7 (400 if sent); deprecated on Opus 4.6 and Sonnet 4.6.\n> **Older models:** Use `.thinking(ThinkingConfigEnabled.builder().budgetTokens(N).build())` (budget must be < `maxTokens`, min 1024).\n\n```java\nimport com.anthropic.models.messages.ContentBlock;\nimport com.anthropic.models.messages.MessageCreateParams;\nimport com.anthropic.models.messages.Model;\nimport com.anthropic.models.messages.ThinkingConfigAdaptive;\n\nMessageCreateParams params = MessageCreateParams.builder()\n .model(Model.CLAUDE_SONNET_4_6)\n .maxTokens(16000L)\n .thinking(ThinkingConfigAdaptive.builder().build())\n .addUserMessage(\"Solve this step by step: 27 * 453\")\n .build();\n\nfor (ContentBlock block : client.messages().create(params).content()) {\n block.thinking().ifPresent(t -> System.out.println(\"[thinking] \" + t.thinking()));\n block.text().ifPresent(t -> System.out.println(t.text()));\n}\n```\n\n`ContentBlock` narrowing: `.thinking()` / `.text()` return `Optional<T>` — use `.ifPresent(...)` or `.stream().flatMap(...)`. Alternative: `isThinking()` / `asThinking()` boolean+unwrap pairs (throws on wrong variant).\n\n---\n\n## Effort Parameter\n\nEffort is nested inside `OutputConfig` — there is NO `.effort()` directly on `MessageCreateParams.Builder`.\n\n```java\nimport com.anthropic.models.messages.OutputConfig;\n\n.outputConfig(OutputConfig.builder()\n .effort(OutputConfig.Effort.HIGH) // or LOW, MEDIUM, MAX\n .build())\n```\n\nCombine with `Thinking = ThinkingConfigAdaptive` for cost-quality control.\n\n---\n\n## Prompt Caching\n\nSystem message as a list of `TextBlockParam` with `CacheControlEphemeral`. Use `.systemOfTextBlockParams(...)` — the plain `.system(String)` overload can't carry cache control. For placement patterns and the silent-invalidator audit checklist, see `shared/prompt-caching.md`.\n\n```java\nimport com.anthropic.models.messages.TextBlockParam;\nimport com.anthropic.models.messages.CacheControlEphemeral;\n\n.systemOfTextBlockParams(List.of(\n TextBlockParam.builder()\n .text(longSystemPrompt)\n .cacheControl(CacheControlEphemeral.builder()\n .ttl(CacheControlEphemeral.Ttl.TTL_1H) // optional; also TTL_5M\n .build())\n .build()))\n```\n\nThere's also a top-level `.cacheControl(CacheControlEphemeral)` on `MessageCreateParams.Builder` and on `Tool.builder()`.\n\nVerify hits via `response.usage().cacheCreationInputTokens()` / `response.usage().cacheReadInputTokens()`.\n\n---\n\n## Token Counting\n\n```java\nimport com.anthropic.models.messages.MessageCountTokensParams;\n\nlong tokens = client.messages().countTokens(\n MessageCountTokensParams.builder()\n .model(Model.CLAUDE_SONNET_4_6)\n .addUserMessage(\"Hello\")\n .build()\n).inputTokens();\n```\n\n---\n\n## PDF / Document Input\n\n`DocumentBlockParam` builder has source shortcuts. Wrap in `ContentBlockParam.ofDocument()` and pass via `.addUserMessageOfBlockParams()`.\n\n```java\nimport com.anthropic.models.messages.DocumentBlockParam;\nimport com.anthropic.models.messages.ContentBlockParam;\nimport com.anthropic.models.messages.TextBlockParam;\n\nDocumentBlockParam doc = DocumentBlockParam.builder()\n .source(Base64PdfSource.builder().data(base64String).build())\n // or .source(UrlPdfSource.builder().url(\"https://...\").build())\n .title(\"My Document\") // optional\n .build();\n```\n\nFor **Files API** document references, use the beta path and beta types — see `files-api.md`: `BetaRequestDocumentBlock.builder().source(BetaFileDocumentSource.builder().fileId(id).build())`.\n\n```java\n.addUserMessageOfBlockParams(List.of(\n ContentBlockParam.ofDocument(doc),\n ContentBlockParam.ofText(TextBlockParam.builder().text(\"Summarize this\").build())))\n```\n\n---\n\n## Stop Details\n\nWhen `stopReason()` is `\"refusal\"`, the response includes structured `stopDetails()`:\n\n```java\nresponse.stopDetails().ifPresent(details -> {\n System.out.println(\"Category: \" + details.category());\n System.out.println(\"Explanation: \" + details.explanation());\n});\n```\n\n**Refusal fallbacks (Claude Fable 5) — opt in by default.** Fallbacks are opt-in: without them a refused request simply stops. New `claude-fable-5` code should include the server-side `fallbacks` parameter (beta header `server-side-fallback-2026-06-01`, fallback model `claude-opus-4-8`, on the beta messages call) by default. The exact Java builder methods (and the client-side middleware for providers without server-side support) are not documented here — WebFetch the Java SDK repo's `examples/` from `shared/live-sources.md`; full semantics in `shared/model-migration.md` → Migrating to Claude Fable 5 → `refusal` stop reason.\n\n---\n\n## Error Type\n\n`AnthropicServiceException` exposes `.errorType()` returning `Optional<ErrorType>` for programmatic error classification:\n\n```java\ntry {\n client.messages().create(params);\n} catch (AnthropicServiceException e) {\n e.errorType().ifPresent(type ->\n System.out.println(\"Error type: \" + type) // RATE_LIMIT_ERROR, OVERLOADED_ERROR, etc.\n );\n}\n```\n\n---\n</doc>\n\n<doc path=\"java/claude-api/files-api.md\">\n# Files API — Java\n\n## Files API (Beta)\n\nUnder `client.beta().files()`. File references in messages need the beta message types (non-beta `DocumentBlockParam.Source` has no file-ID variant).\n\n```java\nimport com.anthropic.models.beta.files.FileUploadParams;\nimport com.anthropic.models.beta.files.FileMetadata;\nimport com.anthropic.models.beta.messages.BetaRequestDocumentBlock;\nimport com.anthropic.models.beta.messages.BetaFileDocumentSource;\nimport java.nio.file.Paths;\n\nFileMetadata meta = client.beta().files().upload(\n FileUploadParams.builder()\n .file(Paths.get(\"/path/to/doc.pdf\")) // or .file(InputStream) or .file(byte[])\n .build());\n\n// Reference in a beta message:\nBetaRequestDocumentBlock doc = BetaRequestDocumentBlock.builder()\n .source(BetaFileDocumentSource.builder().fileId(meta.id()).build())\n .build();\n```\n\nOther methods: `.list()`, `.delete(String fileId)`, `.download(String fileId)`, `.retrieveMetadata(String fileId)`.\n</doc>\n\n<doc path=\"java/claude-api/streaming.md\">\n# Streaming — Java\n\n## Streaming\n\n```java\nimport com.anthropic.core.http.StreamResponse;\nimport com.anthropic.models.messages.RawMessageStreamEvent;\n\nMessageCreateParams params = MessageCreateParams.builder()\n .model(Model.CLAUDE_OPUS_4_8)\n .maxTokens(64000L)\n .addUserMessage(\"Write a haiku\")\n .build();\n\ntry (StreamResponse<RawMessageStreamEvent> streamResponse = client.messages().createStreaming(params)) {\n streamResponse.stream()\n .flatMap(event -> event.contentBlockDelta().stream())\n .flatMap(deltaEvent -> deltaEvent.delta().text().stream())\n .forEach(textDelta -> System.out.print(textDelta.text()));\n}\n```\n\n---\n</doc>\n\n<doc path=\"java/claude-api/tool-use.md\">\n# Tool Use — Java\n\nFor conceptual overview (tool definitions, tool choice, tips), see [shared/tool-use-concepts.md](../../shared/tool-use-concepts.md).\n\n## Tool Use (Beta)\n\nThe Java SDK supports beta tool use with annotated classes. Tool classes implement `Supplier<String>` for automatic execution via `BetaToolRunner`.\n\n### Tool Runner (automatic loop)\n\n```java\nimport com.anthropic.models.beta.messages.MessageCreateParams;\nimport com.anthropic.models.beta.messages.BetaMessage;\nimport com.anthropic.helpers.BetaToolRunner;\nimport com.fasterxml.jackson.annotation.JsonClassDescription;\nimport com.fasterxml.jackson.annotation.JsonPropertyDescription;\nimport java.util.function.Supplier;\n\n@JsonClassDescription(\"Get the weather in a given location\")\nstatic class GetWeather implements Supplier<String> {\n @JsonPropertyDescription(\"The city and state, e.g. San Francisco, CA\")\n public String location;\n\n @Override\n public String get() {\n return \"The weather in \" + location + \" is sunny and 72°F\";\n }\n}\n\nBetaToolRunner toolRunner = client.beta().messages().toolRunner(\n MessageCreateParams.builder()\n .model(\"claude-opus-4-8\")\n .maxTokens(16000L)\n .putAdditionalHeader(\"anthropic-beta\", \"structured-outputs-2025-11-13\")\n .addTool(GetWeather.class)\n .addUserMessage(\"What's the weather in San Francisco?\")\n .build());\n\nfor (BetaMessage message : toolRunner) {\n System.out.println(message);\n}\n```\n\n### Memory Tool\n\nThe Java SDK provides `BetaMemoryToolHandler` for implementing the memory tool backend. You supply a handler that manages file storage, and the `BetaToolRunner` handles memory tool calls automatically.\n\n```java\nimport com.anthropic.helpers.BetaMemoryToolHandler;\nimport com.anthropic.helpers.BetaToolRunner;\nimport com.anthropic.models.beta.messages.BetaMemoryTool20250818;\nimport com.anthropic.models.beta.messages.BetaMessage;\nimport com.anthropic.models.beta.messages.MessageCreateParams;\nimport com.anthropic.models.beta.messages.ToolRunnerCreateParams;\n\n// Implement BetaMemoryToolHandler with your storage backend (e.g., filesystem)\nBetaMemoryToolHandler memoryHandler = new FileSystemMemoryToolHandler(sandboxRoot);\n\nMessageCreateParams createParams = MessageCreateParams.builder()\n .model(\"claude-opus-4-8\")\n .maxTokens(4096L)\n .addTool(BetaMemoryTool20250818.builder().build())\n .addUserMessage(\"Remember that my favorite color is blue\")\n .build();\n\nBetaToolRunner toolRunner = client.beta().messages().toolRunner(\n ToolRunnerCreateParams.builder()\n .betaMemoryToolHandler(memoryHandler)\n .initialMessageParams(createParams)\n .build());\n\nfor (BetaMessage message : toolRunner) {\n System.out.println(message);\n}\n```\n\nSee the [shared memory tool concepts](../../shared/tool-use-concepts.md) for more details on the memory tool.\n\n### Non-Beta Tool Declaration (manual JSON schema)\n\n`Tool.InputSchema.Properties` is a freeform `Map<String, JsonValue>` wrapper — build property schemas via `putAdditionalProperty`. `type: \"object\"` is the default. The builder has a direct `.addTool(Tool)` overload that wraps in `ToolUnion` automatically.\n\n```java\nimport com.anthropic.core.JsonValue;\nimport com.anthropic.models.messages.Tool;\n\nTool tool = Tool.builder()\n .name(\"get_weather\")\n .description(\"Get the current weather in a given location\")\n .inputSchema(Tool.InputSchema.builder()\n .properties(Tool.InputSchema.Properties.builder()\n .putAdditionalProperty(\"location\", JsonValue.from(Map.of(\"type\", \"string\")))\n .build())\n .required(List.of(\"location\"))\n .build())\n .build();\n\nMessageCreateParams params = MessageCreateParams.builder()\n .model(Model.CLAUDE_SONNET_4_6)\n .maxTokens(16000L)\n .addTool(tool)\n .addUserMessage(\"Weather in Paris?\")\n .build();\n```\n\nFor manual tool loops, handle `tool_use` blocks in the response, send `tool_result` back, loop until `stop_reason` is `\"end_turn\"`. See [shared tool use concepts](../../shared/tool-use-concepts.md).\n\n### Building `MessageParam` with Content Blocks (Tool Result Round-Trip)\n\n`MessageParam.Content` is an inner union class (string | list). Use the builder's `.contentOfBlockParams(List<ContentBlockParam>)` alias — there is NO separate `MessageParamContent` class with a static `ofBlockParams`:\n\n```java\nimport com.anthropic.models.messages.MessageParam;\nimport com.anthropic.models.messages.ContentBlockParam;\nimport com.anthropic.models.messages.ToolResultBlockParam;\n\nList<ContentBlockParam> results = List.of(\n ContentBlockParam.ofToolResult(ToolResultBlockParam.builder()\n .toolUseId(toolUseBlock.id())\n .content(yourResultString)\n .build())\n);\n\nMessageParam toolResultMsg = MessageParam.builder()\n .role(MessageParam.Role.USER)\n .contentOfBlockParams(results) // builder alias for Content.ofBlockParams(...)\n .build();\n```\n\n---\n\n## Structured Output\n\nThe class-based overload auto-derives the JSON schema from your POJO and gives you a typed `.text()` return — no manual schema, no manual parsing.\n\n```java\nimport com.anthropic.models.messages.StructuredMessageCreateParams;\n\nrecord Book(String title, String author) {}\nrecord BookList(List<Book> books) {}\n\nStructuredMessageCreateParams<BookList> params = MessageCreateParams.builder()\n .model(Model.CLAUDE_SONNET_4_6)\n .maxTokens(16000L)\n .outputConfig(BookList.class) // returns a typed builder\n .addUserMessage(\"List 3 classic novels\")\n .build();\n\nclient.messages().create(params).content().stream()\n .flatMap(cb -> cb.text().stream())\n .forEach(typed -> {\n // typed.text() returns BookList, not String\n for (Book b : typed.text().books()) System.out.println(b.title());\n });\n```\n\nSupports Jackson annotations: `@JsonPropertyDescription`, `@JsonIgnore`, `@ArraySchema(minItems=...)`. Manual schema path: `OutputConfig.builder().format(JsonOutputFormat.builder().schema(...).build())`.\n\n---\n\n## Anthropic-Defined Tools\n\nVersion-suffixed types; `name`/`type` auto-set by builder. Direct `.addTool()` overloads exist for most tool types; where one is missing (newer or less-common tools — see the advisor note below), wrap via the union type's static factory: `.addTool(BetaToolUnion.of<ToolName>(builder…build()))`. Web search and code execution are server-executed; bash and text editor are client-executed (you handle the `tool_use` locally — see `shared/tool-use-concepts.md`).\n\n```java\nimport com.anthropic.models.messages.WebSearchTool20260209;\nimport com.anthropic.models.messages.ToolBash20250124;\nimport com.anthropic.models.messages.ToolTextEditor20250728;\nimport com.anthropic.models.messages.CodeExecutionTool20260120;\n\n.addTool(WebSearchTool20260209.builder()\n .maxUses(5L) // optional\n .allowedDomains(List.of(\"example.com\")) // optional\n .build())\n.addTool(ToolBash20250124.builder().build())\n.addTool(ToolTextEditor20250728.builder().build())\n.addTool(CodeExecutionTool20260120.builder().build())\n```\n\nAlso available: `WebFetchTool20260209`, `MemoryTool20250818`, `ToolSearchToolBm25_20251119`. For the advisor tool, use `BetaAdvisorTool20260301` in the beta namespace with `.addBeta(\"advisor-tool-2026-03-01\")` (server-side; advisor model ≥ executor model). There is no direct `.addTool(BetaAdvisorTool20260301)` overload on the beta builder — wrap it via the `BetaToolUnion` static factory for the advisor type; if `javac` rejects the specific factory method name, `javap com.anthropic.models.beta.messages.BetaToolUnion | grep -i advisor` shows the exact one.\n\n### Beta namespace (MCP, compaction)\n\nFor beta-only features use `com.anthropic.models.beta.messages.*` — class names have a `Beta` prefix AND live in the beta package. The beta `MessageCreateParams.Builder` has direct `.addTool(BetaToolBash20250124)` overloads AND `.addMcpServer()`:\n\n```java\nimport com.anthropic.models.beta.messages.MessageCreateParams;\nimport com.anthropic.models.beta.messages.BetaToolBash20250124;\nimport com.anthropic.models.beta.messages.BetaCodeExecutionTool20260120;\nimport com.anthropic.models.beta.messages.BetaRequestMcpServerUrlDefinition;\n\nMessageCreateParams params = MessageCreateParams.builder()\n .model(Model.CLAUDE_OPUS_4_8)\n .maxTokens(16000L)\n .addBeta(\"mcp-client-2025-11-20\")\n .addTool(BetaToolBash20250124.builder().build())\n .addTool(BetaCodeExecutionTool20260120.builder().build())\n .addMcpServer(BetaRequestMcpServerUrlDefinition.builder()\n .name(\"my-server\")\n .url(\"https://example.com/mcp\")\n .build())\n .addUserMessage(\"...\")\n .build();\n\nclient.beta().messages().create(params);\n```\n\n`BetaTool*` types are NOT interchangeable with non-beta `Tool*` — pick one namespace per request.\n\n**Reading server-tool blocks in the response:** `ServerToolUseBlock` has `.id()`, `.name()` (enum), and `._input()` returning raw `JsonValue` — there is NO typed `.input()`. For code execution results, unwrap two levels:\n\n```java\nfor (ContentBlock block : response.content()) {\n block.serverToolUse().ifPresent(stu -> {\n System.out.println(\"tool: \" + stu.name() + \" input: \" + stu._input());\n });\n block.codeExecutionToolResult().ifPresent(r -> {\n r.content().resultBlock().ifPresent(result -> {\n System.out.println(\"stdout: \" + result.stdout());\n System.out.println(\"stderr: \" + result.stderr());\n System.out.println(\"exit: \" + result.returnCode());\n });\n });\n}\n```\n\n---\n</doc>\n\n<doc path=\"java/managed-agents/README.md\">\n# Managed Agents — Java\n\n> **Bindings not shown here:** This README covers the most common managed-agents flows for Java. If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the Java SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.\n\n> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `client.beta().agents().create` and pass it to every subsequent `client.beta().sessions().create`; do not call `agents().create` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.\n\n## Installation\n\n```xml\n<dependency>\n <groupId>com.anthropic</groupId>\n <artifactId>anthropic-java</artifactId>\n</dependency>\n```\n\n## Client Initialization\n\n```java\nimport com.anthropic.client.okhttp.AnthropicOkHttpClient;\n\n// Default (uses ANTHROPIC_API_KEY env var)\nvar client = AnthropicOkHttpClient.fromEnv();\n```\n\n---\n\n## Create an Environment\n\n```java\nimport com.anthropic.models.beta.environments.BetaCloudConfigParams;\nimport com.anthropic.models.beta.environments.BetaUnrestrictedNetwork;\nimport com.anthropic.models.beta.environments.EnvironmentCreateParams;\n\nvar environment = client.beta().environments().create(EnvironmentCreateParams.builder()\n .name(\"my-dev-env\")\n .config(BetaCloudConfigParams.builder()\n .networking(BetaUnrestrictedNetwork.builder().build())\n .build())\n .build());\nSystem.out.println(\"Environment ID: \" + environment.id()); // env_...\n```\n\n---\n\n## Create an Agent (required first step)\n\n> ⚠️ **There is no inline agent config.** Model, system, and tools live on the agent object, not the session. Always start with `client.beta().agents().create()` — the session takes either `.agent(agent.id())` or the typed `BetaManagedAgentsAgentParams.builder()...build()`.\n\n### Minimal\n\n```java\nimport com.anthropic.models.beta.agents.AgentCreateParams;\nimport com.anthropic.models.beta.agents.BetaManagedAgentsAgentToolset20260401Params;\nimport com.anthropic.models.beta.sessions.BetaManagedAgentsAgentParams;\nimport com.anthropic.models.beta.sessions.SessionCreateParams;\n\n// 1. Create the agent (reusable, versioned)\nvar agent = client.beta().agents().create(AgentCreateParams.builder()\n .name(\"Coding Assistant\")\n .model(\"claude-opus-4-8\")\n .system(\"You are a helpful coding assistant.\")\n .addTool(BetaManagedAgentsAgentToolset20260401Params.builder()\n .type(BetaManagedAgentsAgentToolset20260401Params.Type.AGENT_TOOLSET_20260401)\n .build())\n .build());\n\n// 2. Start a session\nvar session = client.beta().sessions().create(SessionCreateParams.builder()\n .agent(BetaManagedAgentsAgentParams.builder()\n .type(BetaManagedAgentsAgentParams.Type.AGENT)\n .id(agent.id())\n .version(agent.version())\n .build())\n .environmentId(environment.id())\n .title(\"Quickstart session\")\n .build());\nSystem.out.println(\"Session ID: \" + session.id());\nSystem.out.println(\"Trace: https://platform.claude.com/workspaces/default/sessions/\" + session.id());\n```\n\n### Updating an Agent\n\nUpdates create new versions; the agent object is immutable per version.\n\n```java\nimport com.anthropic.models.beta.agents.AgentUpdateParams;\n\nvar updatedAgent = client.beta().agents().update(agent.id(), AgentUpdateParams.builder()\n .version(agent.version())\n .system(\"You are a helpful coding agent. Always write tests.\")\n .build());\nSystem.out.println(\"New version: \" + updatedAgent.version());\n\n// List all versions\nfor (var version : client.beta().agents().versions().list(agent.id()).autoPager()) {\n System.out.println(\"Version \" + version.version() + \": \" + version.updatedAt());\n}\n\n// Archive the agent\nvar archived = client.beta().agents().archive(agent.id());\nSystem.out.println(\"Archived at: \" + archived.archivedAt().orElseThrow());\n```\n\n---\n\n## Send a User Message\n\n```java\nimport com.anthropic.models.beta.sessions.events.BetaManagedAgentsUserMessageEventParams;\nimport com.anthropic.models.beta.sessions.events.EventSendParams;\n\nclient.beta().sessions().events().send(session.id(), EventSendParams.builder()\n .addEvent(BetaManagedAgentsUserMessageEventParams.builder()\n .type(BetaManagedAgentsUserMessageEventParams.Type.USER_MESSAGE)\n .addTextContent(\"Review the auth module\")\n .build())\n .build());\n```\n\n> 💡 **Stream-first:** Open the stream *before* (or concurrently with) sending the message. The stream only delivers events that occur after it opens — stream-after-send means early events arrive buffered in one batch. See [Steering Patterns](../../shared/managed-agents-events.md#steering-patterns).\n\n---\n\n## Stream Events (SSE)\n\n```java\nimport com.anthropic.models.beta.sessions.events.StreamEvents;\n\n// Open the stream first, then send the user message\ntry (var stream = client.beta().sessions().events().streamStreaming(session.id())) {\n client.beta().sessions().events().send(session.id(), EventSendParams.builder()\n .addEvent(BetaManagedAgentsUserMessageEventParams.builder()\n .type(BetaManagedAgentsUserMessageEventParams.Type.USER_MESSAGE)\n .addTextContent(\"Summarize the repo README\")\n .build())\n .build());\n\n for (var event : (Iterable<StreamEvents>) stream.stream()::iterator) {\n if (event.isAgentMessage()) {\n event.asAgentMessage().content().forEach(block -> System.out.print(block.text()));\n } else if (event.isAgentToolUse()) {\n System.out.println(\"\\n[Using tool: \" + event.asAgentToolUse().name() + \"]\");\n } else if (event.isSessionStatusIdle()) {\n break;\n } else if (event.isSessionError()) {\n System.out.println(\"\\n[Error]\");\n break;\n }\n }\n}\n```\n\n### Reconnecting and Tailing\n\nWhen reconnecting mid-session, list past events first to dedupe, then tail live events. The cross-variant `id` field is read from the raw `_json()` value:\n\n```java\nimport com.anthropic.core.JsonValue;\nimport java.util.HashSet;\nimport java.util.Map;\nimport java.util.Optional;\n\ntry (var stream = client.beta().sessions().events().streamStreaming(session.id())) {\n // Stream is open and buffering. List history before tailing live.\n var seenEventIds = new HashSet<String>();\n for (var past : client.beta().sessions().events().list(session.id()).autoPager()) {\n Optional<Map<String, JsonValue>> obj = past._json().orElseThrow().asObject();\n seenEventIds.add(obj.orElseThrow().get(\"id\").asStringOrThrow());\n }\n\n // Tail live events, skipping anything already seen\n for (var event : (Iterable<StreamEvents>) stream.stream()::iterator) {\n Optional<Map<String, JsonValue>> obj = event._json().orElseThrow().asObject();\n if (!seenEventIds.add(obj.orElseThrow().get(\"id\").asStringOrThrow())) continue;\n if (event.isAgentMessage()) {\n event.asAgentMessage().content().forEach(block -> System.out.print(block.text()));\n } else if (event.isSessionStatusIdle()) {\n break;\n }\n }\n}\n```\n\n---\n\n## Provide Custom Tool Result\n\n> ℹ️ The Java managed-agents bindings for `user.custom_tool_result` are not yet documented in this skill or in the apps source examples.

Array-shape syntax (camelCase keys) is idiomatic. For placement patterns and the silent-invalidator audit checklist, see `shared/prompt-caching.md`.\n\n```php\n$message = $client->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n system: [\n ['type' => 'text', 'text' => $longSystemPrompt, 'cacheControl' => ['type' => 'ephemeral']],\n ],\n messages: [['role' => 'user', 'content' => 'Summarize the key points']],\n);\n```\n\nFor 1-hour TTL: `'cacheControl' => ['type' => 'ephemeral', 'ttl' => '1h']`. There's also a top-level `cacheControl:` on `messages->create(...)` that auto-places on the last cacheable block.\n\nVerify hits via `$message->usage->cacheCreationInputTokens` / `$message->usage->cacheReadInputTokens`.\n\n---\n\n## Stop Details\n\nWhen `stopReason` is `'refusal'`, the response includes structured `stopDetails`:\n\n```php\nif ($message->stopReason === 'refusal' && $message->stopDetails !== null) {\n echo \"Category: \" . $message->stopDetails->category . \"\\n\"; // e.g. \"cyber\", \"bio\", \"reasoning_extraction\", \"frontier_llm\", or null — see docs for the full set\n echo \"Explanation: \" . $message->stopDetails->explanation . \"\\n\";\n}\n```\n\n**Refusal fallbacks (Claude Fable 5) — opt in by default.** Fallbacks are opt-in: without them a refused request simply stops. New `claude-fable-5` code should include the server-side `fallbacks` parameter (beta header `server-side-fallback-2026-06-01`, fallback model `claude-opus-4-8`, on the beta messages call) by default.

Define tools with `BetaRunnableTool` — a definition array plus a `run` closure:\n\n```php\nuse Anthropic\\Lib\\Tools\\BetaRunnableTool;\n\n$weatherTool = new BetaRunnableTool(\n definition: [\n 'name' => 'get_weather',\n 'description' => 'Get the current weather for a location.',\n 'inputSchema' => [\n 'type' => 'object',\n 'properties' => [\n 'location' => ['type' => 'string', 'description' => 'City and state'],\n ],\n 'required' => ['location'],\n ],\n ],\n run: function (array $input): string {\n return \"The weather in {$input['location']} is sunny and 72°F.\";\n },\n);\n\n$runner = $client->beta->messages->toolRunner(\n maxTokens: 16000,\n messages: [['role' => 'user', 'content' => 'What is the weather in Paris?']],\n model: 'claude-opus-4-8',\n tools: [$weatherTool],\n);\n\nforeach ($runner as $message) {\n foreach ($message->content as $block) {\n if ($block->type === 'text') {\n echo $block->text;\n }\n }\n}\n```\n\n### Manual Loop\n\nTools are passed as arrays. **The SDK uses camelCase keys** (`inputSchema`, `toolUseID`, `stopReason`) and auto-maps to the API's snake_case on the wire — since v0.5.0. See [shared tool use concepts](../../shared/tool-use-concepts.md) for the loop pattern.\n\n```php\nuse Anthropic\\Messages\\ToolUseBlock;\n\n$tools = [\n [\n 'name' => 'get_weather',\n 'description' => 'Get the current weather in a given location',\n 'inputSchema' => [ // camelCase, not input_schema\n 'type' => 'object',\n 'properties' => [\n 'location' => ['type' => 'string', 'description' => 'City and state'],\n ],\n 'required' => ['location'],\n ],\n ],\n];\n\n$messages = [['role' => 'user', 'content' => 'What is the weather in SF?']];\n\n$response = $client->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n tools: $tools,\n messages: $messages,\n);\n\nwhile ($response->stopReason === 'tool_use') { // camelCase property\n $toolResults = [];\n foreach ($response->content as $block) {\n if ($block instanceof ToolUseBlock) {\n // $block->name : string — tool name to dispatch on\n // $block->input : array<string,mixed> — parsed JSON input\n // $block->id : string — pass back as toolUseID\n $result = executeYourTool($block->name, $block->input);\n $toolResults[] = [\n 'type' => 'tool_result',\n 'toolUseID' => $block->id, // camelCase, not tool_use_id\n 'content' => $result,\n ];\n }\n }\n\n // Append assistant turn + user turn with tool results\n $messages[] = ['role' => 'assistant', 'content' => $response->content];\n $messages[] = ['role' => 'user', 'content' => $toolResults];\n\n $response = $client->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n tools: $tools,\n messages: $messages,\n );\n}\n\n// Final text response\nforeach ($response->content as $block) {\n if ($block->type === 'text') {\n echo $block->text;\n }\n}\n```\n\n`$block->type === 'tool_use'` also works; `instanceof ToolUseBlock` narrows for PHPStan.\n\n\n---\n\n## Structured Outputs\n\n### Using StructuredOutputModel (Recommended)\n\nDefine a PHP class implementing `StructuredOutputModel` and pass it as `outputConfig`:\n\n```php\nuse Anthropic\\Lib\\Contracts\\StructuredOutputModel;\nuse Anthropic\\Lib\\Concerns\\StructuredOutputModelTrait;\nuse Anthropic\\Lib\\Attributes\\Constrained;\n\nclass Person implements StructuredOutputModel\n{\n use StructuredOutputModelTrait;\n\n #[Constrained(description: 'Full name')]\n public string $name;\n\n public int $age;\n\n public ?string $email = null; // nullable = optional field\n}\n\n$message = $client->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n messages: [['role' => 'user', 'content' => 'Generate a profile for Alice, age 30']],\n outputConfig: ['format' => Person::class],\n);\n\n$person = $message->parsedOutput(); // Person instance\necho $person->name;\n```\n\nTypes are inferred from PHP type hints. Use `#[Constrained(description: '...')]` to add descriptions. Nullable properties (`?string`) become optional fields.\n\n### Raw Schema\n\n```php\n$message = $client->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n messages: [['role' => 'user', 'content' => 'Extract: John (john@co.com), Enterprise plan']],\n outputConfig: [\n 'format' => [\n 'type' => 'json_schema',\n 'schema' => [\n 'type' => 'object',\n 'properties' => [\n 'name' => ['type' => 'string'],\n 'email' => ['type' => 'string'],\n 'plan' => ['type' => 'string'],\n ],\n 'required' => ['name', 'email', 'plan'],\n 'additionalProperties' => false,\n ],\n ],\n ],\n);\n\n// First text block contains valid JSON\nforeach ($message->content as $block) {\n if ($block->type === 'text') {\n $data = json_decode($block->text, true);\n break;\n }\n}\n```\n\n---\n\n## Beta Features & Anthropic-Defined Tools\n\n**`betas:` is NOT a param on `$client->messages->create()`** — it only exists on the beta namespace. Use it for features that need an explicit opt-in header:\n\n```php\nuse Anthropic\\Beta\\Messages\\BetaRequestMCPServerURLDefinition;\n\n$response = $client->beta->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n mcpServers: [\n BetaRequestMCPServerURLDefinition::with(\n name: 'my-server',\n url: 'https://example.com/mcp',\n ),\n ],\n betas: ['mcp-client-2025-11-20'], // only valid on ->beta->messages\n messages: [['role' => 'user', 'content' => 'Use the MCP tools']],\n);\n```\n\n### Task budgets\n\n```php\n$response = $client->beta->messages->create(\n model: 'claude-opus-4-8',\n maxTokens: 16000,\n outputConfig: ['taskBudget' => ['type' => 'tokens', 'total' => 64000]],\n tools: [...],\n messages: [...],\n betas: ['task-budgets-2026-03-13'],\n);\n```\n\n### Cache diagnostics\n\nPass the previous response's `id` on the next request; print the `diagnostics` object on the response:\n\n```php\n$r2 = $client->beta->messages->create(\n model: 'claude-opus-4-8', maxTokens: 1024,\n diagnostics: ['previousMessageId' => $r1->id],\n betas: ['cache-diagnosis-2026-04-07'],\n messages: [...],\n);\n```\n\n**Anthropic-defined tools** (bash, web_search, text_editor, code_execution) are GA and work on both paths. Of these, web_search and code_execution are server-executed; bash and text_editor are client-executed (you handle the `tool_use` locally) — `Anthropic\\Messages\\ToolBash20250124` / `WebSearchTool20260209` / `ToolTextEditor20250728` / `CodeExecutionTool20260120` for non-beta, `Anthropic\\Beta\\Messages\\BetaToolBash20250124` / `BetaWebSearchTool20260209` / `BetaToolTextEditor20250728` / `BetaCodeExecutionTool20260120` for beta. No `betas:` header needed for these.\n\n### Tool search (non-beta, server-side)\n\n```php\ntools: [\n ['type' => 'tool_search_tool_regex_20251119', 'name' => 'tool_search_tool_regex'],\n ['name' => 'get_weather', 'description' => '...', 'inputSchema' => [...], 'deferLoading' => true],\n // ... other user tools with 'deferLoading' => true\n],\n```\n\n### Memory tool (non-beta, client-executed)\n\nDeclare `['type' => 'memory_20250818', 'name' => 'memory']`. Handle the `tool_use` by reading/writing files under a fixed `/memories` directory. **Validate every model-supplied path**: resolve to its canonical form and verify it remains within the memory directory; reject traversal (`..`, symlinks) — see `shared/tool-use-concepts.md` § Client-Side Tools.\n\n---\n</doc>\n\n<doc path=\"php/managed-agents/README.md\">\n# Managed Agents — PHP\n\n> **Bindings not shown here:** This README covers the most common managed-agents flows for PHP. If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the PHP SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.\n\n> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `$client->beta->agents->create` and pass it to every subsequent `->sessions->create`; do not call `agents->create` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.\n\n## Installation\n\n```bash\ncomposer require \"anthropic-ai/sdk\" \"guzzlehttp/guzzle:^7\"\n```\n\n## Client Initialization\n\n```php\nuse Anthropic\\Client;\n\n// Default (uses ANTHROPIC_API_KEY env var)\n$client = new Client();\n\n// Explicit API key\n$client = new Client(apiKey: 'your-api-key');\n```\n\n---\n\n## Create an Environment\n\n```php\n$environment = $client->beta->environments->create(\n name: 'my-dev-env',\n config: ['type' => 'cloud', 'networking' => ['type' => 'unrestricted']],\n);\necho \"Environment ID: {$environment->id}\\n\"; // env_...\n```\n\n---\n\n## Create an Agent (required first step)\n\n> ⚠️ **There is no inline agent config.** `model`/`system`/`tools` live on the agent object, not the session. Always start with `$client->beta->agents->create()` — the session takes either `agent: $agent->id` or the typed `BetaManagedAgentsAgentParams::with(type: 'agent', id: $agent->id, version: $agent->version)`.\n\n### Minimal\n\n```php\nuse Anthropic\\Beta\\Agents\\BetaManagedAgentsAgentToolset20260401Params;\n\n// 1. Create the agent (reusable, versioned)\n$agent = $client->beta->agents->create(\n name: 'Coding Assistant',\n model: 'claude-opus-4-8',\n system: 'You are a helpful coding assistant.',\n tools: [\n BetaManagedAgentsAgentToolset20260401Params::with(\n type: 'agent_toolset_20260401',\n ),\n ],\n);\n\n// 2. Start a session\n$session = $client->beta->sessions->create(\n agent: ['type' => 'agent', 'id' => $agent->id, 'version' => $agent->version],\n environmentID: $environment->id,\n title: 'Quickstart session',\n);\necho \"Session ID: {$session->id}\\n\";\necho \"Trace: https://platform.claude.com/workspaces/default/sessions/{$session->id}\\n\";\n```\n\n### Updating an Agent\n\nUpdates create new versions; the agent object is immutable per version.\n\n```php\n$updatedAgent = $client->beta->agents->update(\n $agent->id,\n version: $agent->version,\n system: 'You are a helpful coding agent. Always write tests.',\n);\necho \"New version: {$updatedAgent->version}\\n\";\n\n// List all versions\nforeach ($client->beta->agents->versions->list($agent->id)->pagingEachItem() as $version) {\n echo \"Version {$version->version}: {$version->updatedAt->format(DateTimeInterface::ATOM)}\\n\";\n}\n\n// Archive the agent\n$archived = $client->beta->agents->archive($agent->id);\necho \"Archived at: {$archived->archivedAt->format(DateTimeInterface::ATOM)}\\n\";\n```\n\n---\n\n## Send a User Message\n\n```php\n$client->beta->sessions->events->send(\n $session->id,\n events: [\n [\n 'type' => 'user.message',\n 'content' => [['type' => 'text', 'text' => 'Review the auth module']],\n ],\n ],\n);\n```\n\n> 💡 **Stream-first:** Open the stream *before* (or concurrently with) sending the message. The stream only delivers events that occur after it opens — stream-after-send means early events arrive buffered in one batch. See [Steering Patterns](../../shared/managed-agents-events.md#steering-patterns).\n\n---\n\n## Stream Events (SSE)\n\n> ℹ️ **Streaming transporter:** PHP's default buffered PSR-18 client never returns for the open-ended session event stream. Use a streaming Guzzle transporter for `streamStream()` calls — other calls keep the default client.\n\n```php\n$streamingClient = new GuzzleHttp\\Client(['stream' => true]);\n\n// Open the stream first, then send the user message\n$stream = $client->beta->sessions->events->streamStream(\n $session->id,\n requestOptions: ['transporter' => $streamingClient],\n);\n$client->beta->sessions->events->send(\n $session->id,\n events: [\n [\n 'type' => 'user.message',\n 'content' => [['type' => 'text', 'text' => 'Summarize the repo README']],\n ],\n ],\n);\n\nforeach ($stream as $event) {\n match ($event->type) {\n 'agent.message' => array_walk(\n $event->content,\n static fn($block) => $block->type === 'text' ? print($block->text) : null,\n ),\n 'agent.tool_use' => print(\"\\n[Using tool: {$event->name}]\\n\"),\n 'session.error' => printf(\"\\n[Error: %s]\", $event->error?->message ?? 'unknown'),\n default => null,\n };\n if ($event->type === 'session.status_idle' || $event->type === 'session.error') {\n break;\n }\n}\n$stream->close();\n```\n\n### Reconnecting and Tailing\n\nWhen reconnecting mid-session, list past events first to dedupe, then tail live events:\n\n```php\n$stream = $client->beta->sessions->events->streamStream(\n $session->id,\n requestOptions: ['transporter' => $streamingClient],\n);\n\n// Stream is open and buffering. List history before tailing live.\n$seenEventIds = [];\nforeach ($client->beta->sessions->events->list($session->id)->pagingEachItem() as $event) {\n $seenEventIds[$event->id] = true;\n}\n\n// Tail live events, skipping anything already seen\nforeach ($stream as $event) {\n if (isset($seenEventIds[$event->id])) {\n continue;\n }\n $seenEventIds[$event->id] = true;\n match ($event->type) {\n 'agent.message' => array_walk(\n $event->content,\n static fn($block) => $block->type === 'text' ? print($block->text) : null,\n ),\n default => null,\n };\n if ($event->type === 'session.status_idle') {\n break;\n }\n}\n$stream->close();\n```\n\n---\n\n## Provide Custom Tool Result\n\n> ℹ️ The PHP managed-agents bindings for `user.custom_tool_result` are not yet documented in this skill or in the apps source examples. Refer to `shared/managed-agents-events.md` for the wire format and the `anthropic-ai/sdk` PHP repository for the corresponding params.\n\n---\n\n## Poll Events\n\n```php\nforeach ($client->beta->sessions->events->list($session->id)->pagingEachItem() as $event) {\n echo \"{$event->type}: {$event->id}\\n\";\n}\n```\n\n---\n\n## Upload a File\n\n> ℹ️ **PHP file upload:** The PHP SDK's beta managed-agents file upload binding is not shown in the apps source examples; the canonical PHP example uses raw cURL against `POST /v1/files`. If your codebase prefers the SDK, WebFetch the `anthropic-ai/sdk` PHP repository for the latest binding before writing code.\n\n```php\nuse Anthropic\\Beta\\Sessions\\BetaManagedAgentsFileResourceParams;\n\n// Raw cURL upload (canonical example from the apps source)\n$csvPath = 'data.csv';\n$ch = curl_init('https://api.anthropic.com/v1/files');\ncurl_setopt_array($ch, [\n CURLOPT_RETURNTRANSFER => true,\n CURLOPT_POST => true,\n CURLOPT_HTTPHEADER => [\n 'x-api-key: ' . getenv('ANTHROPIC_API_KEY'),\n 'anthropic-version: 2023-06-01',\n 'anthropic-beta: files-api-2025-04-14',\n ],\n CURLOPT_POSTFIELDS => ['file' => new CURLFile($csvPath, 'text/csv', 'data.csv')],\n]);\n$file = json_decode(curl_exec($ch));\necho \"File ID: {$file->id}\\n\";\n\n// Mount in a session\n$session = $client->beta->sessions->create(\n agent: $agent->id,\n environmentID: $environment->id,\n resources: [\n BetaManagedAgentsFileResourceParams::with(\n type: 'file',\n fileID: $file->id,\n mountPath: '/workspace/data.csv',\n ),\n ],\n);\n```\n\n### Add and Manage Resources on an Existing Session\n\n```php\n// Attach an additional file to an open session\n$resource = $client->beta->sessions->resources->add(\n $session->id,\n type: 'file',\n fileID: $file->id,\n);\necho \"{$resource->id}\\n\";

Set `max_retries` on the client or via `with_options()`; `max_retries=0` disables.\n\n### Async performance (aiohttp backend)\n\nFor high-concurrency async workloads, install `anthropic[aiohttp]` and pass `DefaultAioHttpClient` instead of the default httpx backend:\n\n```python\nfrom anthropic import AsyncAnthropic, DefaultAioHttpClient\n\nasync with AsyncAnthropic(http_client=DefaultAioHttpClient()) as client:\n ...\n```\n\n### Custom HTTP client (proxy, base URL)\n\nUse `DefaultHttpxClient` / `DefaultAsyncHttpxClient` — not raw `httpx.Client` — so the SDK's default timeouts and connection limits are preserved:\n\n```python\nfrom anthropic import Anthropic, DefaultHttpxClient\n\nclient = Anthropic(\n base_url=\"http://my.test.server.example.com:8083\", # or ANTHROPIC_BASE_URL env var\n http_client=DefaultHttpxClient(proxy=\"http://my.test.proxy.example.com\"),\n)\n```\n\n### Logging\n\nSet `ANTHROPIC_LOG=debug` (or `info`) to enable SDK logging via the standard `logging` module.\n\n---\n\n## Basic Message Request\n\n```python\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[\n {\"role\": \"user\", \"content\": \"What is the capital of France?\"}\n ]\n)\n# response.content is a list of content block objects (TextBlock, ThinkingBlock,\n# ToolUseBlock, ...). Check .type before accessing .text.\nfor block in response.content:\n if block.type == \"text\":\n print(block.text)\n```\n\n---\n\n## System Prompts\n\n```python\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n system=\"You are a helpful coding assistant. Always provide examples in Python.\",\n messages=[{\"role\": \"user\", \"content\": \"How do I read a JSON file?\"}]\n)\n```\n\n### Mid-conversation system messages (model-gated)\n\nFor operator instructions that arrive mid-conversation (mode switches, injected state), append `{\"role\": \"system\", ...}` to `messages` instead of editing top-level `system` — this preserves the cached prefix and carries operator authority. Must follow a user message (or an `assistant` message ending in server-tool use), and must be either the last entry in `messages` or be followed by an `assistant` turn; cannot be `messages[0]`. Unsupported models return a 400 (`role 'system' is not supported on this model`). See `shared/prompt-caching.md` for when to use this vs. top-level `system`.\n\n```python\nresponse = client.messages.create(\n model=MODEL_ID, # must support mid-conversation system messages\n max_tokens=16000,\n system=[{\"type\": \"text\", \"text\": STABLE_SYSTEM, \"cache_control\": {\"type\": \"ephemeral\"}}],\n messages=history + [\n {\"role\": \"user\", \"content\": user_message},\n {\"role\": \"system\", \"content\": \"Terse mode enabled — keep responses under 40 words.\"},\n ],\n) # No beta header needed — use regular client.messages.create\n```\n\n---\n\n## Vision (Images)\n\n### Base64\n\n```python\nimport base64\n\nwith open(\"image.png\", \"rb\") as f:\n image_data = base64.standard_b64encode(f.read()).decode(\"utf-8\")\n\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\n \"role\": \"user\",\n \"content\": [\n {\n \"type\": \"image\",\n \"source\": {\n \"type\": \"base64\",\n \"media_type\": \"image/png\",\n \"data\": image_data\n }\n },\n {\"type\": \"text\", \"text\": \"What's in this image?\"}\n ]\n }]\n)\n```\n\n### URL\n\n```python\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\n \"role\": \"user\",\n \"content\": [\n {\n \"type\": \"image\",\n \"source\": {\n \"type\": \"url\",\n \"url\": \"https://example.com/image.png\"\n }\n },\n {\"type\": \"text\", \"text\": \"Describe this image\"}\n ]\n }]\n)\n```\n\n---\n\n## Prompt Caching\n\nCache large context to reduce costs (up to 90% savings). **Caching is a prefix match** — any byte change anywhere in the prefix invalidates everything after it. For placement patterns, architectural guidance (frozen system prompt, deterministic tool order, where to put volatile content), and the silent-invalidator audit checklist, read `shared/prompt-caching.md`.\n\n### Automatic Caching (Recommended)\n\nUse top-level `cache_control` to automatically cache the last cacheable block in the request — no need to annotate individual content blocks:\n\n```python\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n cache_control={\"type\": \"ephemeral\"}, # auto-caches the last cacheable block\n system=\"You are an expert on this large document...\",\n messages=[{\"role\": \"user\", \"content\": \"Summarize the key points\"}]\n)\n```\n\n### Manual Cache Control\n\nFor fine-grained control, add `cache_control` to specific content blocks:\n\n```python\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n system=[{\n \"type\": \"text\",\n \"text\": \"You are an expert on this large document...\",\n \"cache_control\": {\"type\": \"ephemeral\"} # default TTL is 5 minutes\n }],\n messages=[{\"role\": \"user\", \"content\": \"Summarize the key points\"}]\n)\n\n# With explicit TTL (time-to-live)\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n system=[{\n \"type\": \"text\",\n \"text\": \"You are an expert on this large document...\",\n \"cache_control\": {\"type\": \"ephemeral\", \"ttl\": \"1h\"} # 1 hour TTL\n }],\n messages=[{\"role\": \"user\", \"content\": \"Summarize the key points\"}]\n)\n```\n\n### Verifying Cache Hits\n\n```python\nprint(response.usage.cache_creation_input_tokens) # tokens written to cache (~1.25x cost)\nprint(response.usage.cache_read_input_tokens) # tokens served from cache (~0.1x cost)\nprint(response.usage.input_tokens) # uncached tokens (full cost)\n```\n\nIf `cache_read_input_tokens` is zero across repeated identical-prefix requests, a silent invalidator is at work — `datetime.now()` or a UUID in the system prompt, unsorted `json.dumps()`, or a varying tool set. See `shared/prompt-caching.md` for the full audit table.\n\n---\n\n## Extended Thinking\n\n> **Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6:** Use adaptive thinking. `budget_tokens` is removed on Fable 5, Opus 4.8, and 4.7 (400 if sent); deprecated on Opus 4.6 and Sonnet 4.6.\n> **Older models:** Use `thinking: {type: \"enabled\", budget_tokens: N}` (must be < `max_tokens`, min 1024).\n\n```python\n# Fable 5 / Opus 4.8 / 4.7 / 4.6: adaptive thinking (recommended)\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n thinking={\"type\": \"adaptive\", \"display\": \"summarized\"}, # display opt-in: default is omitted (empty thinking text) on Fable 5 / Mythos 5 / Opus 4.8 / 4.7\n output_config={\"effort\": \"high\"}, # low | medium | high | max\n messages=[{\"role\": \"user\", \"content\": \"Solve this step by step...\"}]\n)\n\n# Access thinking and response\nfor block in response.content:\n if block.type == \"thinking\":\n print(f\"Thinking: {block.thinking}\")\n elif block.type == \"text\":\n print(f\"Response: {block.text}\")\n```\n\n---\n\n## Error Handling\n\n```python\nimport anthropic\n\ntry:\n response = client.messages.create(...)\nexcept anthropic.BadRequestError as e:\n print(f\"Bad request: {e.message}\")\nexcept anthropic.AuthenticationError:\n print(\"Invalid API key\")\nexcept anthropic.PermissionDeniedError:\n print(\"API key lacks required permissions\")\nexcept anthropic.NotFoundError:\n print(\"Invalid model or endpoint\")\nexcept anthropic.RateLimitError as e:\n retry_after = int(e.response.headers.get(\"retry-after\", \"60\"))\n print(f\"Rate limited.

Retry later.\")\n else:\n print(f\"API error: {e.message}\")\nexcept anthropic.APIConnectionError:\n print(\"Network error. Check internet connection.\")\n```\n\n---\n\n## Response Helpers\n\nEvery response object exposes `_request_id` (populated from the `request-id` header) — log it when reporting failures to Anthropic. Despite the underscore prefix, this property is public.\n\n```python\nmessage = client.messages.create(...)\nprint(message._request_id) # req_018EeWyXxfu5pfWkrYcMdjWG\nprint(message.to_json()) # serialize the Pydantic model\nprint(message.to_dict()) # plain dict\n```\n\nTo access raw headers or other response metadata, use `.with_raw_response`:\n\n```python\nraw = client.messages.with_raw_response.create(\n model=\"claude-opus-4-8\",\n max_tokens=1024,\n messages=[{\"role\": \"user\", \"content\": \"Hello\"}],\n)\nprint(raw.headers.get(\"request-id\"))\nmessage = raw.parse() # the Message object messages.create() would have returned\n```\n\n---\n\n## Multi-Turn Conversations\n\nThe API is stateless — send the full conversation history each time.\n\n```python\nclass ConversationManager:\n \"\"\"Manage multi-turn conversations with the Claude API.\"\"\"\n\n def __init__(self, client: anthropic.Anthropic, model: str, system: str = None):\n self.client = client\n self.model = model\n self.system = system\n self.messages = []\n\n def send(self, user_message: str, **kwargs) -> str:\n \"\"\"Send a message and get a response.\"\"\"\n self.messages.append({\"role\": \"user\", \"content\": user_message})\n\n response = self.client.messages.create(\n model=self.model,\n max_tokens=kwargs.get(\"max_tokens\", 16000),\n system=self.system,\n messages=self.messages,\n **kwargs\n )\n\n assistant_message = next(\n (b.text for b in response.content if b.type == \"text\"), \"\"\n )\n self.messages.append({\"role\": \"assistant\", \"content\": assistant_message})\n\n return assistant_message\n\n# Usage\nconversation = ConversationManager(\n client=anthropic.Anthropic(),\n model=\"claude-opus-4-8\",\n system=\"You are a helpful assistant.\"\n)\n\nresponse1 = conversation.send(\"My name is Alice.\")\nresponse2 = conversation.send(\"What's my name?\") # Claude remembers \"Alice\"\n```\n\n**Rules:**\n\n- Consecutive same-role messages are allowed — the API combines them into a single turn\n- First message must be `user`\n- `role: \"system\"` messages are allowed mid-conversation on supporting models (no beta header needed) — see § Mid-conversation system messages above\n\n---\n\n### Compaction (long conversations)\n\n> **Beta, Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6.** When conversations approach the 200K context window, compaction automatically summarizes earlier context server-side. The API returns a `compaction` block; you must pass it back on subsequent requests — append `response.content`, not just the text.\n\n```python\nimport anthropic\n\nclient = anthropic.Anthropic()\nmessages = []\n\ndef chat(user_message: str) -> str:\n messages.append({\"role\": \"user\", \"content\": user_message})\n\n response = client.beta.messages.create(\n betas=[\"compact-2026-01-12\"],\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=messages,\n context_management={\n \"edits\": [{\"type\": \"compact_20260112\"}]\n }\n )\n\n # Append full content — compaction blocks must be preserved\n messages.append({\"role\": \"assistant\", \"content\": response.content})\n\n return next(block.text for block in response.content if block.type == \"text\")\n\n# Compaction triggers automatically when context grows large\nprint(chat(\"Help me build a Python web scraper\"))\nprint(chat(\"Add support for JavaScript-rendered pages\"))\nprint(chat(\"Now add rate limiting and error handling\"))\n```\n\n---\n\n## Stop Reasons\n\nThe `stop_reason` field in the response indicates why the model stopped generating:\n\n| Value | Meaning |\n|-------|---------|\n| `end_turn` | Claude finished its response naturally |\n| `max_tokens` | Hit the `max_tokens` limit — increase it or use streaming |\n| `stop_sequence` | Hit a custom stop sequence |\n| `tool_use` | Claude wants to call a tool — execute it and continue |\n| `pause_turn` | Model paused and can be resumed (agentic flows) |\n| `refusal` | Claude refused for safety reasons — check `stop_details` |\n\n### Structured Stop Details\n\nWhen `stop_reason` is `\"refusal\"`, the response includes a `stop_details` object with structured information about the refusal:\n\n```python\nif response.stop_reason == \"refusal\" and response.stop_details:\n print(f\"Category: {response.stop_details.category}\") # e.g. \"cyber\", \"bio\", \"reasoning_extraction\", \"frontier_llm\", or None — see docs for the full set\n print(f\"Explanation: {response.stop_details.explanation}\")\n```\n\n### Refusal Fallbacks (Claude Fable 5) — opt in by default\n\nFallbacks are **opt-in**: without them a refused request simply stops. Include the server-side `fallbacks` parameter in `claude-fable-5` code by default — on a policy decline the API re-runs the same request on the fallback model inside the same call. A decline before any output isn't billed (a mid-stream decline bills the streamed partial); the rescue bills at the fallback model's own rates, with cache repricing applied automatically.\n\n```python\nresponse = client.beta.messages.create(\n model=\"claude-fable-5\",\n max_tokens=16000,\n betas=[\"server-side-fallback-2026-06-01\"],\n fallbacks=[{\"model\": \"claude-opus-4-8\"}],\n messages=[{\"role\": \"user\", \"content\": \"...\"}],\n)\n\n# Switch points: one fallback block per model that ran and declined this turn\nfor block in response.content:\n if block.type == \"fallback\":\n print(f\"{block.from_.model} declined; {block.to.model} continued\")\n\n# Served-by signal — covers sticky turns, which carry no fallback block.\n# Pair with stop_reason: the fallback model can itself refuse.\nfallback_ran = any(\n entry.type == \"fallback_message\" for entry in response.usage.iterations or []\n)\nif fallback_ran and response.stop_reason != \"refusal\":\n print(f\"Served by {response.model}\")\n```\n\nA `stop_reason: \"refusal\"` on the final response means the whole chain refused. The header must be exactly `server-side-fallback-2026-06-01`; the parameter is rejected on the Batches API and unavailable on Amazon Bedrock, Vertex AI, and Microsoft Foundry — register the client-side `BetaRefusalFallbackMiddleware` on the client there instead. Full semantics (sticky routing, billing, streaming, echoing fallback turns back): `shared/model-migration.md` → Migrating to Claude Fable 5 → `refusal` stop reason.\n\n---\n\n## Cost Optimization Strategies\n\n### 1. Use Prompt Caching for Repeated Context\n\n```python\n# Automatic caching (simplest — caches the last cacheable block)\nresponse = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n cache_control={\"type\": \"ephemeral\"},\n system=large_document_text, # e.g., 50KB of context\n messages=[{\"role\": \"user\", \"content\": \"Summarize the key points\"}]\n)\n\n# First request: full cost\n# Subsequent requests: ~90% cheaper for cached portion\n```\n\n### 2. Choose the Right Model\n\n```python\n# Default to Opus for most tasks\nresponse = client.messages.create(\n model=\"claude-opus-4-8\", # $5.00/$25.00 per 1M tokens\n max_tokens=16000,\n messages=[{\"role\": \"user\", \"content\": \"Explain quantum computing\"}]\n)\n\n# Use Sonnet for high-volume production workloads\nstandard_response = client.messages.create(\n model=\"claude-sonnet-5\", # $3.00/$15.00 per 1M tokens\n max_tokens=16000,\n messages=[{\"role\": \"user\", \"content\": \"Summarize this document\"}]\n)\n\n# Use Haiku only for simple, speed-critical tasks\nsimple_response = client.messages.create(\n model=\"claude-haiku-4-5\", # $1.00/$5.00 per 1M tokens\n max_tokens=256,\n messages=[{\"role\": \"user\", \"content\": \"Classify this as positive or negative\"}]\n)\n```\n\n### 3. Use Token Counting Before Requests\n\n```python\ncount_response = client.messages.count_tokens(\n model=\"claude-opus-4-8\",\n messages=messages,\n system=system\n)\n\nestimated_input_cost = count_response.input_tokens * 0.000005 # $5/1M tokens\nprint(f\"Estimated input cost: ${estimated_input_cost:.4f}\")\n```\n\n---\n\n## Retry with Exponential Backoff\n\n> **Note:** The Anthropic SDK automatically retries rate limit (429) and server errors (5xx) with exponential backoff. You can configure this with `max_retries` (default: 2). Only implement custom retry logic if you need behavior beyond what the SDK provides.\n\n```python\nimport time\nimport random\nimport anthropic\n\ndef call_with_retry(\n client: anthropic.Anthropic,\n max_retries: int = 5,\n base_delay: float = 1.0,\n max_delay: float = 60.0,\n **kwargs\n):\n \"\"\"Call the API with exponential backoff retry.\"\"\"\n last_exception = None\n\n for attempt in range(max_retries):\n try:\n return client.messages.create(**kwargs)\n except anthropic.RateLimitError as e:\n last_exception = e\n except anthropic.APIStatusError as e:\n if e.status_code >= 500:\n last_exception = e\n else:\n raise # Client errors (4xx except 429) should not be retried\n\n delay = min(base_delay * (2 ** attempt) + random.uniform(0, 1), max_delay)\n print(f\"Retry {attempt + 1}/{max_retries} after {delay:.1f}s\")\n time.sleep(delay)\n\n raise last_exception\n```\n</doc>\n\n<doc path=\"python/claude-api/batches.md\">\n# Message Batches API — Python\n\nThe Batches API (`POST /v1/messages/batches`) processes Messages API requests asynchronously at 50% of standard prices.\n\n## Key Facts\n\n- Up to 100,000 requests or 256 MB per batch\n- Most batches complete within 1 hour; maximum 24 hours\n- Results available for 29 days after creation\n- 50% cost reduction on all token usage\n- All Messages API features supported (vision, tools, caching, etc.)\n\n---\n\n## Create a Batch\n\n```python\nimport anthropic\nfrom anthropic.types.message_create_params import MessageCreateParamsNonStreaming\nfrom anthropic.types.messages.batch_create_params import Request\n\nclient = anthropic.Anthropic()\n\nmessage_batch = client.messages.batches.create(\n requests=[\n Request(\n custom_id=\"request-1\",\n params=MessageCreateParamsNonStreaming(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\"role\": \"user\", \"content\": \"Summarize climate change impacts\"}]\n )\n ),\n Request(\n custom_id=\"request-2\",\n params=MessageCreateParamsNonStreaming(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\"role\": \"user\", \"content\": \"Explain quantum computing basics\"}]\n )\n ),\n ]\n)\n\nprint(f\"Batch ID: {message_batch.id}\")\nprint(f\"Status: {message_batch.processing_status}\")\n```\n\n---\n\n## Poll for Completion\n\n```python\nimport time\n\nwhile True:\n batch = client.messages.batches.retrieve(message_batch.id)\n if batch.processing_status == \"ended\":\n break\n print(f\"Status: {batch.processing_status}, processing: {batch.request_counts.processing}\")\n time.sleep(60)\n\nprint(\"Batch complete!\")\nprint(f\"Succeeded: {batch.request_counts.succeeded}\")\nprint(f\"Errored: {batch.request_counts.errored}\")\n```\n\n---\n\n## Retrieve Results\n\n> **Note:** Examples below use `match/case` syntax, requiring Python 3.10+.

Only use `.data` if you want the first page only.\n\n```python\nfor f in client.beta.files.list():\n print(f\"{f.id}: {f.filename} ({f.size_bytes} bytes)\")\n```\n\n### Get File Metadata\n\n```python\nfile_info = client.beta.files.retrieve_metadata(\"file_011CNha8iCJcU1wXNR6q4V8w\")\nprint(f\"Filename: {file_info.filename}\")\nprint(f\"MIME type: {file_info.mime_type}\")\n```\n\n### Delete a File\n\n```python\nclient.beta.files.delete(\"file_011CNha8iCJcU1wXNR6q4V8w\")\n```\n\n### Download a File\n\nOnly files created by the code execution tool or skills can be downloaded (not user-uploaded files).\n\n```python\nfile_content = client.beta.files.download(\"file_011CNha8iCJcU1wXNR6q4V8w\")\nfile_content.write_to_file(\"output.txt\")\n```\n\n---\n\n## Full End-to-End Example\n\nUpload a document once, ask multiple questions about it:\n\n```python\nimport anthropic\n\nclient = anthropic.Anthropic()\n\n# 1. Upload once\nuploaded = client.beta.files.upload(\n file=(\"contract.pdf\", open(\"contract.pdf\", \"rb\"), \"application/pdf\"),\n)\nprint(f\"Uploaded: {uploaded.id}\")\n\n# 2. Ask multiple questions using the same file_id\nquestions = [\n \"What are the key terms and conditions?\",\n \"What is the termination clause?\",\n \"Summarize the payment schedule.\",\n]\n\nfor question in questions:\n response = client.beta.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\n \"role\": \"user\",\n \"content\": [\n {\"type\": \"text\", \"text\": question},\n {\n \"type\": \"document\",\n \"source\": {\"type\": \"file\", \"file_id\": uploaded.id}\n }\n ]\n }],\n betas=[\"files-api-2025-04-14\"],\n )\n print(f\"\\nQ: {question}\")\n text = next((b.text for b in response.content if b.type == \"text\"), \"\")\n print(f\"A: {text[:200]}\")\n\n# 3. Clean up when done\nclient.beta.files.delete(uploaded.id)\n```\n</doc>\n\n<doc path=\"python/claude-api/streaming.md\">\n# Streaming — Python\n\n## Quick Start\n\n```python\nwith client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n messages=[{\"role\": \"user\", \"content\": \"Write a story\"}]\n) as stream:\n for text in stream.text_stream:\n print(text, end=\"\", flush=True)\n```\n\n### Async\n\n```python\nasync with async_client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n messages=[{\"role\": \"user\", \"content\": \"Write a story\"}]\n) as stream:\n async for text in stream.text_stream:\n print(text, end=\"\", flush=True)\n```\n\n### Low-level: `stream=True`\n\n`messages.stream()` (above) is the recommended helper — it accumulates state and exposes `text_stream` / `get_final_message()`. If you only need the raw event iterator and want lower memory use, pass `stream=True` to `messages.create()` instead:\n\n```python\nfor event in client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n messages=[{\"role\": \"user\", \"content\": \"Write a story\"}],\n stream=True,\n):\n print(event.type)\n```\n\nNo final-message accumulation is done for you in this form.\n\n---\n\n## Handling Different Content Types\n\nClaude may return text, thinking blocks, or tool use. Handle each appropriately:\n\n> **Fable 5 / Opus 4.8 / Opus 4.7 / Opus 4.6:** Use `thinking: {type: \"adaptive\"}`. On older models, use `thinking: {type: \"enabled\", budget_tokens: N}` instead.\n\n```python\nwith client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n thinking={\"type\": \"adaptive\", \"display\": \"summarized\"}, # display opt-in: default is omitted (empty thinking text) on Fable 5 / Mythos 5 / Opus 4.8 / 4.7\n messages=[{\"role\": \"user\", \"content\": \"Analyze this problem\"}]\n) as stream:\n for event in stream:\n if event.type == \"content_block_start\":\n if event.content_block.type == \"thinking\":\n print(\"\\n[Thinking...]\")\n elif event.content_block.type == \"text\":\n print(\"\\n[Response:]\")\n\n elif event.type == \"content_block_delta\":\n if event.delta.type == \"thinking_delta\":\n print(event.delta.thinking, end=\"\", flush=True)\n elif event.delta.type == \"text_delta\":\n print(event.delta.text, end=\"\", flush=True)\n```\n\n---\n\n## Streaming with Tool Use\n\nThe Python tool runner currently returns complete messages. Use streaming for individual API calls within a manual loop if you need per-token streaming with tools:\n\n```python\nwith client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n tools=tools,\n messages=messages\n) as stream:\n for text in stream.text_stream:\n print(text, end=\"\", flush=True)\n\n response = stream.get_final_message()\n # Continue with tool execution if response.stop_reason == \"tool_use\"\n```\n\n---\n\n## Getting the Final Message\n\n```python\nwith client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n messages=[{\"role\": \"user\", \"content\": \"Hello\"}]\n) as stream:\n for text in stream.text_stream:\n print(text, end=\"\", flush=True)\n\n # Get full message after streaming\n final_message = stream.get_final_message()\n print(f\"\\n\\nTokens used: {final_message.usage.output_tokens}\")\n```\n\n---\n\n## Streaming with Progress Updates\n\n```python\ndef stream_with_progress(client, **kwargs):\n \"\"\"Stream a response with progress updates.\"\"\"\n total_tokens = 0\n content_parts = []\n\n with client.messages.stream(**kwargs) as stream:\n for event in stream:\n if event.type == \"content_block_delta\":\n if event.delta.type == \"text_delta\":\n text = event.delta.text\n content_parts.append(text)\n print(text, end=\"\", flush=True)\n\n elif event.type == \"message_delta\":\n if event.usage and event.usage.output_tokens is not None:\n total_tokens = event.usage.output_tokens\n\n final_message = stream.get_final_message()\n\n print(f\"\\n\\n[Tokens used: {total_tokens}]\")\n return \"\".join(content_parts)\n```\n\n---\n\n## Error Handling in Streams\n\n```python\ntry:\n with client.messages.stream(\n model=\"claude-opus-4-8\",\n max_tokens=64000,\n messages=[{\"role\": \"user\", \"content\": \"Write a story\"}]\n ) as stream:\n for text in stream.text_stream:\n print(text, end=\"\", flush=True)\nexcept anthropic.APIConnectionError:\n print(\"\\nConnection lost. Please retry.\")\nexcept anthropic.RateLimitError:\n print(\"\\nRate limited. Please wait and retry.\")\nexcept anthropic.APIStatusError as e:\n print(f\"\\nAPI error: {e.status_code}\")\n```\n\n---\n\n## Stream Event Types\n\n| Event Type | Description | When it fires |\n| --------------------- | --------------------------- | --------------------------------- |\n| `message_start` | Contains message metadata | Once at the beginning |\n| `content_block_start` | New content block beginning | When a text/tool_use block starts |\n| `content_block_delta` | Incremental content update | For each token/chunk |\n| `content_block_stop` | Content block complete | When a block finishes |\n| `message_delta` | Message-level updates | Contains `stop_reason`, usage |\n| `message_stop` | Message complete | Once at the end |\n\n## Best Practices\n\n1. **Always flush output** — Use `flush=True` to show tokens immediately\n2. **Handle partial responses** — If the stream is interrupted, you may have incomplete content\n3. **Track token usage** — The `message_delta` event contains usage information\n4. **Use timeouts** — Set appropriate timeouts for your application\n5. **Default to streaming** — Use `.get_final_message()` to get the complete response even when streaming, giving you timeout protection without needing to handle individual events\n6. **Large `max_tokens` without streaming raises `ValueError`** — The SDK refuses non-streaming requests it estimates will exceed ~10 minutes (idle connections drop). Pass `stream=True` / use `messages.stream()`, or explicitly override `timeout`, to suppress the guard.\n</doc>\n\n<doc path=\"python/claude-api/tool-use.md\">\n# Tool Use — Python\n\nFor conceptual overview (tool definitions, tool choice, tips), see [shared/tool-use-concepts.md](../../shared/tool-use-concepts.md).\n\n## Tool Runner (Recommended)\n\n**Beta:** The tool runner is in beta in the Python SDK.\n\nUse the `@beta_tool` decorator to define tools as typed functions, then pass them to `client.beta.messages.tool_runner()`:\n\n```python\nimport anthropic\nfrom anthropic import beta_tool\n\nclient = anthropic.Anthropic()\n\n@beta_tool\ndef get_weather(location: str, unit: str = \"celsius\") -> str:\n \"\"\"Get current weather for a location.\n\n Args:\n location: City and state, e.g., San Francisco, CA.\n unit: Temperature unit, either \"celsius\" or \"fahrenheit\".\n \"\"\"\n # Your implementation here\n return f\"72°F and sunny in {location}\"\n\n# The tool runner handles the agentic loop automatically\nrunner = client.beta.messages.tool_runner(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n tools=[get_weather],\n messages=[{\"role\": \"user\", \"content\": \"What's the weather in Paris?\"}],\n)\n\n# Each iteration yields a BetaMessage; iteration stops when Claude is done\nfor message in runner:\n print(message)\n```\n\nFor async usage, use `@beta_async_tool` with `async def` functions.\n\n**Key benefits of the tool runner:**\n\n- No manual loop — the SDK handles calling tools and feeding results back\n- Type-safe tool inputs via decorators\n- Tool schemas are generated automatically from function signatures\n- Iteration stops automatically when Claude has no more tool calls\n\n---\n\n## MCP Tool Conversion Helpers\n\n**Beta.** Convert [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) tools, prompts, and resources to Anthropic API types for use with the tool runner. Requires `pip install anthropic[mcp]` (Python 3.10+).\n\n> **Note:** The Claude API also supports an `mcp_servers` parameter that lets Claude connect directly to remote MCP servers. Use these helpers instead when you need local MCP servers, prompts, resources, or more control over the MCP connection.\n\n### MCP Tools with Tool Runner\n\n```python\nfrom anthropic import AsyncAnthropic\nfrom anthropic.lib.tools.mcp import async_mcp_tool\nfrom mcp import ClientSession\nfrom mcp.client.stdio import stdio_client, StdioServerParameters\n\nclient = AsyncAnthropic()\n\nasync with stdio_client(StdioServerParameters(command=\"mcp-server\")) as (read, write):\n async with ClientSession(read, write) as mcp_client:\n await mcp_client.initialize()\n\n tools_result = await mcp_client.list_tools()\n # tool_runner is sync — returns the runner, not a coroutine\n runner = client.beta.messages.tool_runner(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\"role\": \"user\", \"content\": \"Use the available tools\"}],\n tools=[async_mcp_tool(t, mcp_client) for t in tools_result.tools],\n )\n async for message in runner:\n print(message)\n```\n\nFor sync usage, use `mcp_tool` instead of `async_mcp_tool`.\n\n### MCP Prompts\n\n```python\nfrom anthropic.lib.tools.mcp import mcp_message\n\nprompt = await mcp_client.get_prompt(name=\"my-prompt\")\nresponse = await client.beta.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[mcp_message(m) for m in prompt.messages],\n)\n```\n\n### MCP Resources as Content\n\n```python\nfrom anthropic.lib.tools.mcp import mcp_resource_to_content\n\nresource = await mcp_client.read_resource(uri=\"file:///path/to/doc.txt\")\nresponse = await client.beta.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n messages=[{\n \"role\": \"user\",\n \"content\": [\n mcp_resource_to_content(resource),\n {\"type\": \"text\", \"text\": \"Summarize this document\"},\n ],\n }],\n)\n```\n\n### Upload MCP Resources as Files\n\n```python\nfrom anthropic.lib.tools.mcp import mcp_resource_to_file\n\nresource = await mcp_client.read_resource(uri=\"file:///path/to/data.json\")\nuploaded = await client.beta.files.upload(file=mcp_resource_to_file(resource))\n```\n\nConversion functions raise `UnsupportedMCPValueError` if an MCP value cannot be converted (e.g., unsupported content types like audio, unsupported MIME types).\n\n---\n\n## Manual Agentic Loop\n\nUse this when you need fine-grained control over the loop (e.g., custom logging, conditional tool execution, human-in-the-loop approval):\n\n```python\nimport anthropic\n\nclient = anthropic.Anthropic()\ntools = [...] # Your tool definitions\nmessages = [{\"role\": \"user\", \"content\": user_input}]\n\n# Agentic loop: keep going until Claude stops calling tools\nwhile True:\n response = client.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=16000,\n tools=tools,\n messages=messages\n )\n\n # If Claude is done (no more tool calls), break\n if response.stop_reason == \"end_turn\":\n break\n\n # Server-side tool hit iteration limit;

If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the Python SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.\n\n> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.create` and pass it to every subsequent `sessions.create`; do not call `agents.create` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.\n\n## Installation\n\n```bash\npip install anthropic\n```\n\n## Client Initialization\n\n```python\nimport anthropic\n\n# Default — resolves credentials from the environment:\n# ANTHROPIC_API_KEY, or ANTHROPIC_AUTH_TOKEN, or an `ant auth login` profile.\n# Prefer this for local dev; don't hardcode a key.\nclient = anthropic.Anthropic()\n\n# Explicit API key (only when you must inject a specific key)\nclient = anthropic.Anthropic(api_key=\"your-api-key\")\n```\n\n---\n\n## Create an Environment\n\n```python\nenvironment = client.beta.environments.create(\n name=\"my-dev-env\",\n config={\n \"type\": \"cloud\",\n \"networking\": {\"type\": \"unrestricted\"},\n },\n)\nprint(environment.id) # env_...\n```\n\n---\n\n## Create an Agent (required first step)\n\n> ⚠️ **There is no inline agent config.** `model`/`system`/`tools` live on the agent object, not the session. Always start with `agents.create()` — the session only takes `agent={\"type\": \"agent\", \"id\": agent.id}`.\n\n### Minimal\n\n```python\n# 1. Create the agent (reusable, versioned)\nagent = client.beta.agents.create(\n name=\"Coding Assistant\",\n model=\"claude-opus-4-8\",\n tools=[{\"type\": \"agent_toolset_20260401\", \"default_config\": {\"enabled\": True}}],\n)\n\n# 2.

The stream only delivers events that occur after it opens — stream-after-send means early events arrive buffered in one batch.

For a hard wall-clock deadline, track `time.monotonic()` at the loop level and bail explicitly, or wrap with `asyncio.wait_for()`.

For per-tool mechanics and code examples, see `tool-use-concepts.md` and the language-specific folders.\n\n---\n\n## Model Parameters\n\n| Parameter | When to use it | What to expect |\n| --- | --- | --- |\n| **Adaptive thinking** (`thinking: {type: \"adaptive\"}`) | When you want Claude to control when and how much to think. | Claude determines thinking depth per request and automatically interleaves thinking between tool calls. No token budget to tune. |\n| **Effort** (`output_config: {effort: ...}`) | When adjusting the tradeoff between thoroughness and token efficiency. | Lower effort → fewer and more-consolidated tool calls, less preamble, terser confirmations. `medium` is often a favorable balance. Use `max` when correctness matters more than cost. |\n\nSee `SKILL.md` §Thinking & Effort for model support and parameter details.\n\n---\n\n## Designing Your Tool Surface\n\n### Bash vs. dedicated tools\n\nClaude doesn't know your application's security boundary, approval policy, or UX surface. Claude emits tool calls; your harness handles them. The shape of those tool calls determines what the harness can do.\n\nA **bash tool** gives Claude broad programmatic leverage — it can perform almost any action. But it gives the harness only an opaque command string, the same shape for every action. Promoting an action to a **dedicated tool** gives the harness an action-specific hook with typed arguments it can intercept, gate, render, or audit.\n\n**When to promote an action to a dedicated tool:**\n\n- **Security boundary.** Actions that require gating are natural candidates. Reversibility is a useful criterion: hard-to-reverse actions (external API calls, sending messages, deleting data) can be gated behind user confirmation. A `send_email` tool is easy to gate; `bash -c \"curl -X POST ...\"` is not.\n- **Staleness checks.** A dedicated `edit` tool can reject writes if the file changed since Claude last read it. Bash can't enforce that invariant.\n- **Rendering.** Some actions benefit from custom UI. Claude Code promotes question-asking to a tool so it can render as a modal, present options, and block the agent loop until answered.\n- **Scheduling.** Read-only tools like `glob` and `grep` can be marked parallel-safe. When the same actions run through bash, the harness can't tell a parallel-safe `grep` from a parallel-unsafe `git push`, so it must serialize.\n\n**Rule of thumb:** Start with bash for breadth. Promote to dedicated tools when you need to gate, render, audit, or parallelize the action.\n\n---\n\n## Anthropic-Provided Tools\n\n| Tool | Side | When to use it | What to expect |\n| --- | --- | --- | --- |\n| **Bash** | Client | Claude needs to execute shell commands. | Claude emits commands; your harness executes them. Reference implementation provided. |\n| **Text editor** | Client | Claude needs to read or edit files. | Claude views, creates, and edits files via your implementation. Reference implementation provided. |\n| **Computer use** | Client or Server | Claude needs to interact with GUIs, web apps, or visual interfaces. | Claude takes screenshots and issues mouse/keyboard commands. Can be self-hosted (you run the environment) or Anthropic-hosted. |\n| **Code execution** | Server | Claude needs to run code in a sandbox you don't want to manage. | Anthropic-hosted container with built-in file and bash sub-tools. No client-side execution. |\n| **Web search / fetch** | Server | Claude needs information past its training cutoff (news, current events, recent docs) or the content of a specific URL. | Claude issues a query or URL; Anthropic executes it and returns results with citations. |\n| **Memory** | Client | Claude needs to save context across sessions. | Claude reads/writes a `/memories` directory. You implement the storage backend. |\n\n**Client-side** tools are defined by Anthropic (name, schema, Claude's usage pattern) but executed by your harness. Anthropic provides reference implementations. **Server-side** tools run entirely on Anthropic infrastructure — declare them in `tools` and Claude handles the rest.\n\n---\n\n## Composing Tool Calls: Programmatic Tool Calling\n\nWith standard tool use, each tool call is a round trip: Claude calls the tool, the result lands in Claude's context, Claude reasons about it, then calls the next tool. Three sequential actions (read profile → look up orders → check inventory) means three round trips. Each adds latency and tokens, and most of the intermediate data is never needed again.\n\n**Programmatic tool calling (PTC)** lets Claude compose those calls into a script instead. The script runs in the code execution container. When the script calls a tool, the container pauses, the call is executed (client-side or server-side), and the result returns to the running code — not to Claude's context. The script processes it with normal control flow (loops, filters, branches). Only the script's final output returns to Claude.\n\n| When to use it | What to expect |\n| --- | --- |\n| Many sequential tool calls, or large intermediate results you want filtered before they hit the context window. | Claude writes code that invokes tools as functions. Runs in the code execution container. Token cost scales with final output, not intermediate results. |\n\n---\n\n## Scaling the Tool and Instruction Set\n\n| Feature | When to use it | What to expect |\n| --- | --- | --- |\n| **Tool search** | Many tools available, but only a few relevant per request. Don't want all schemas in context upfront. | Claude searches the tool set and loads only relevant schemas. Tool definitions are appended, not swapped — preserves cache (see Caching below). |\n| **Skills** | Task-specific instructions Claude should load only when relevant. | Each skill is a folder with a `SKILL.md`. The skill's description sits in context by default; Claude reads the full file when the task calls for it. |\n\nBoth patterns keep the fixed context small and load detail on demand.\n\n---\n\n## Long-Running Agents: Managing Context\n\n| Pattern | When to use it | What to expect |\n| --- | --- | --- |\n| **Context editing** | Context grows stale over many turns (old tool results, completed thinking). | Tool results and thinking blocks are cleared based on configurable thresholds. Keeps the transcript lean without summarizing. |\n| **Compaction** | Conversation likely to reach or exceed the context window limit. | Earlier context is summarized into a compaction block server-side. See `SKILL.md` §Compaction for the critical `response.content` handling. |\n| **Memory** | State must persist across sessions (not just within one conversation). | Claude reads/writes files in a memory directory. Survives process restarts. |\n\n**Choosing between them:** Context editing and compaction operate within a session — editing prunes stale turns, compaction summarizes when you're near the limit. Memory is for cross-session persistence. Many long-running agents use all three.\n\n---\n\n## Caching for Agents\n\n**Read `prompt-caching.md` first.** It covers the prefix-match invariant, breakpoint placement, the silent-invalidator audit, and why changing tools or models mid-session breaks the cache. This section covers only the agent-specific workarounds for those constraints.\n\n| Constraint (from `prompt-caching.md`) | Agent-specific workaround |\n| --- | --- |\n| Editing the system prompt mid-session invalidates the cache. | Append a `{\"role\": \"system\", ...}` message to `messages[]` instead (no beta header; on supporting models — see `prompt-caching.md` § Mid-conversation system messages). The cached prefix stays intact, and the model treats it as an operator-authority instruction rather than user text. On models that don't support it, fall back to a `<system-reminder>` text block in the user turn. |\n| Switching models mid-session invalidates the cache. | Spawn a **subagent** with the cheaper model for the sub-task; keep the main loop on one model. |\n| Adding/removing tools mid-session invalidates the cache. | Use **tool search** for dynamic discovery — it appends tool schemas rather than swapping them, so the existing prefix is preserved. |\n\nFor multi-turn breakpoint placement, use top-level auto-caching — see `prompt-caching.md` §Placement patterns.\n\n---\n\nFor live documentation on any of these features, see `live-sources.md`.\n</doc>\n\n<doc path=\"shared/anthropic-cli.md\">\n# Anthropic CLI (`ant`)\n\nThe `ant` CLI exposes every Claude API resource as a shell subcommand. Compared to `curl`: request bodies are built from typed flags or piped YAML instead of hand-written JSON, `@path` inlines file contents into any string field, `--transform` extracts fields with a GJSON path (no `jq`), list endpoints auto-paginate (cap total results with `--max-items N`; `--limit` only sets the server page size), and the `beta:` prefix auto-sets the right `anthropic-beta` header.\n\n## When to use the CLI vs the SDK\n\n**CLI for the control plane, SDK for the data plane.** Agents and environments are relatively static resources you define, configure, and debug with `ant` — check the YAML into your repo, apply from CI, inspect from a terminal. Sessions are dynamic and driven by your application through the SDK — create per task, stream events, react to tool calls, integrate into your product. Both hit the same API; the split is about where the call lives, not what's possible.\n\n| | Control plane → `ant` | Data plane → SDK |\n|---|---|---|\n| Resources | agents, environments, skills, vaults, files | sessions, events |\n| Cadence | Once per deploy / ad-hoc | Every task / every turn |\n| Lives in | `*.yaml` in your repo + CI + terminal | Application code |\n| Typical calls | `create < agent.yaml`, `update --version N`, `list`, `retrieve`, `archive`, `--debug` | `sessions.create()`, `events.stream()`, `events.send()` |\n\n## Install and auth\n\n```sh\n# macOS\nbrew install anthropics/tap/ant\nxattr -d com.apple.quarantine \"$(brew --prefix)/bin/ant\"\n\n# Linux / WSL — pick the release from github.com/anthropics/anthropic-cli/releases\ncurl -fsSL \"https://github.com/anthropics/anthropic-cli/releases/download/v${VERSION}/ant_${VERSION}_$(uname -s | tr A-Z a-z)_$(uname -m | sed -e s/x86_64/amd64/ -e s/aarch64/arm64/).tar.gz\" \\\n | sudo tar -xz -C /usr/local/bin ant\n\n# Or from source (Go 1.22+)\ngo install github.com/anthropics/anthropic-cli/cmd/ant@latest\n```\n\n**Auth** — the CLI resolves credentials the same way the SDKs do (first match wins): explicit flags, then `ANTHROPIC_API_KEY`, then `ANTHROPIC_AUTH_TOKEN`, then the `ANTHROPIC_PROFILE`-selected or active profile, then Workload Identity Federation env vars, then the default profile on disk. Override the host with `ANTHROPIC_BASE_URL` or `--base-url`.\n\n- **API key**: set `ANTHROPIC_API_KEY` in the environment.\n- **OAuth profile** (no static key to manage): `ant auth login` opens a browser, exchanges for a short-lived token, and stores a profile under `$ANTHROPIC_CONFIG_DIR` (default `~/.config/anthropic/` on Linux/macOS, `%APPDATA%\\Anthropic` on Windows — `configs/<profile>.json` for settings, `credentials/<profile>.json` for tokens). Subsequent `ant` (and SDK) calls pick it up automatically — a bare `Anthropic()` client works after login, but scripts that read `ANTHROPIC_API_KEY` directly do not. Claude Code and the Claude Agent SDK honor the same profile resolution. `ant auth status` shows which credential source and profile won (it reports status only — don't script against its exit code as a health check); `ant auth logout` clears the active profile (`--all` for every profile). On a remote host without a browser, `ant auth login --no-browser` prints the authorize URL and accepts the code back in the terminal.\n- **Non-interactive workloads** (CI, servers, containers): interactive login is for development on your own machine — use Workload Identity Federation instead (see the authentication docs via `shared/live-sources.md`).\n\n> **The #1 auth trap:** profiles are only consulted when no API key is set. A stale exported `ANTHROPIC_API_KEY` silently overrides every profile — requests hit whatever org/workspace that key is scoped to. `ant auth status` shows which source won; unset the key (or per-command: `env -u ANTHROPIC_API_KEY ant …`) before relying on a profile. Truly **unset** it — an empty `ANTHROPIC_API_KEY=\"\"` still wins its precedence slot and authenticates with an empty key. The same shadowing applies in reverse to Claude Code: after `ant auth login`, Claude Code may warn about an auth conflict between the profile and its own `/login` credential — keep one (use the profile and `/logout` in Claude Code, or `ant auth logout` to keep Claude Code's own login).\n\n**Named profiles** — an interactive-login token is bound to a single org+workspace, and the API only shows resources belonging to that workspace. If an agent, session, or file you created \"disappears\", the usual cause is a token scoped to a different workspace than the one that created it (`ant auth status` shows the active workspace). Multi-workspace work means one profile per workspace:\n\n```sh\nant auth login --profile <name> # creates the profile if it doesn't exist; org/workspace picker in browser\nant auth login --profile <name> --workspace-id wrkspc_01... # bind directly, skip the picker\nant profile activate <name> # switch the default profile\nant --profile <name> models list # one-off; equivalent: ANTHROPIC_PROFILE=<name> ant models list\nant profile list # inspect\nant profile set workspace_id wrkspc_01... --profile <name> # edit config keys (workspace_id, base_url, organization_id, …)\n```\n\n`ant profile set` edits an existing profile's config — it never creates one, and it does **not** rebind already-issued credentials; run `ant auth login` again under that profile to mint a token for the new target. Pointing `ANTHROPIC_PROFILE` at a profile that doesn't exist is an error, not a fall-through. Refresh tokens eventually hard-expire (they don't slide with use) — when a previously working profile starts failing auth, re-run `ant auth login` before debugging anything else.\n\n**Scopes** — a profile's OAuth scope set is requested at login (`--scope`) and persists on the profile (`scope` is also a `profile set` config key; like other config edits, changing it requires a fresh `ant auth login` to take effect). Privileged scopes — e.g. `org:admin` for organization-administration endpoints — are **not** in the default scope set: pass the full set you want explicitly (`ant auth login --profile admin --scope \"... org:admin\"`), and the server grants a privileged scope only if your role actually has it. Because the scope set rides on every token the profile mints, keep privileged work on a dedicated profile (`admin` vs `default`) and do day-to-day inference on the unprivileged one, switching with `--profile`/`ANTHROPIC_PROFILE`. Check `ant auth login --help` for the current scope list, and `ant auth status` to see what the active token carries.\n\nTo hand the active credential to a subprocess or raw-HTTP script:\n\n```sh\n# Bare access token — for curl's Authorization header\ncurl https://api.anthropic.com/v1/messages \\\n -H \"Authorization: Bearer $(ant auth print-credentials --access-token)\" \\\n -H \"anthropic-version: 2023-06-01\" \\\n -H \"anthropic-beta: oauth-2025-04-20\" \\\n -H \"content-type: application/json\" \\\n -d '{\"model\": \"claude-opus-4-8\", \"max_tokens\": 1024, \"messages\": [{\"role\": \"user\", \"content\": \"Hello\"}]}'\n\n# .env format — sets ANTHROPIC_AUTH_TOKEN (and ANTHROPIC_BASE_URL if the profile has one).\n# Output is bare KEY=value (no `export`), so use `set -a` to auto-export for child processes:\nset -a; eval \"$(ant auth print-credentials --env)\"; set +a\npython my_script.py # SDK picks up ANTHROPIC_AUTH_TOKEN\n```\n\nOAuth tokens go on `Authorization: Bearer` (not `x-api-key:`) **plus the `anthropic-beta: oauth-2025-04-20` header** — converting a raw curl/httpx script from an API key is a header change, not a key swap. The beta header requirement is endpoint-dependent (some endpoints happen to work without it; `/v1/messages` does not) — always send it so requests don't break when you switch endpoints. The token is short-lived and not auto-refreshed when passed via env var, so re-run `print-credentials` before it expires for long-running scripts (`print-credentials` itself refreshes the token if needed). If both `ANTHROPIC_API_KEY` and `ANTHROPIC_AUTH_TOKEN` are set, the SDKs send both and the API rejects the request — unset `ANTHROPIC_API_KEY` before `eval`ing the `--env` output.\n\n**Foot-gun:** `ant auth print-credentials` with **no flags** prints the entire credentials JSON, not the bare token — putting that in an `Authorization` header yields an empty response or HTTP/2 protocol error. Always use `--access-token` for headers (it always reads the named/active profile; a set `ANTHROPIC_API_KEY` doesn't override credential printing).\n\n## Command structure\n\n```\nant <resource>[:<subresource>] <action> [flags]\n```\n\nBeta resources (agents, sessions, environments, deployments, skills, vaults, memory stores) live under `beta:` — the CLI auto-sends the right `anthropic-beta` header, so don't pass it yourself unless overriding with `--beta <header>`. For self-hosted environments, `ant beta:worker poll/run` and `ant beta:environments:work stats/stop` drive and monitor the work queue — see `shared/managed-agents-self-hosted-sandboxes.md`.\n\n```sh\nant models list\nant messages create --model claude-opus-4-8 --max-tokens 1024 --message '{role: user, content: \"Hello\"}'\nant beta:agents retrieve --agent-id agent_01...\nant beta:sessions:events list --session-id session_01...\n```\n\n`ant --help` lists resources; append `--help` to any subcommand for its flags.\n\n## Global flags\n\n| Flag | Purpose |\n| --- | --- |\n| `--format` | `auto` (default: pretty if TTY, compact if piped), `json`, `jsonl`, `yaml`, `pretty`, `raw`, `explore` (interactive TUI) |\n| `--transform` | GJSON path applied to the response (per-item on list endpoints). Not applied when `--format raw`. |\n| `-r`, `--raw-output` | If the transformed result is a string, print it without quotes (jq semantics). Pair with `--transform` for scalar capture. |\n| `--max-items` | Cap total results returned from auto-paginating list endpoints (distinct from `--limit`, which is the server page size). |\n| `--format-error` / `--transform-error` | Same as `--format`/`--transform`, applied to error responses. `-r` does not apply to the error path — use `--format-error yaml` for unquoted error scalars. |\n| `--base-url` | Override API host |\n| `--debug` | Print full HTTP request + response to stderr (API key redacted) |\n\n## Output — `--transform` + `--format`\n\n`--transform` takes a [GJSON path](https://github.com/tidwall/gjson/blob/master/SYNTAX.md). On list endpoints it runs **per item**, not on the envelope.\n\n```sh\nant beta:agents list --transform '{id,name,model}' --format jsonl\n```\n\n**Extract a scalar for shell use:** pair `--transform` with `-r` (`--raw-output` — prints strings unquoted, jq-style):\n\n```sh\nAGENT_ID=$(ant beta:agents create --name \"My Agent\" --model '{id: claude-sonnet-5}' \\\n --transform id -r)\n```\n\n## Input — flags, stdin, `@file`\n\n**Flags** — scalar fields map directly. Structured fields accept relaxed-YAML syntax (unquoted keys) or strict JSON. Repeatable flags build arrays (each `--tool`, `--event`, `--message` appends one element):\n\n```sh\nant beta:agents create \\\n --name \"Research Agent\" \\\n --model '{id: claude-opus-4-8}' \\\n --tool '{type: agent_toolset_20260401}' \\\n --tool '{type: custom, name: search_docs, input_schema: {type: object, properties: {query: {type: string}}}}'\n```\n\n**Stdin** — pipe a full JSON or YAML body. Merged with flags; flags win on conflict (for array fields, any flag **replaces** the stdin array entirely — it does not append). Quote the heredoc delimiter (`<<'YAML'`) to disable shell expansion inside the body:\n\n```sh\nant beta:agents create <<'YAML'\nname: Research Agent\nmodel: claude-opus-4-8\nsystem: |\n You are a research assistant.

Inside structured flag values, quote the path. Binary files are auto-base64'd; force with `@file://` (text) or `@data://` (base64). Escape a literal leading `@` as `\\@`.\n\n```sh\nant beta:agents create --name \"Researcher\" --model '{id: claude-sonnet-5}' --system @./prompts/researcher.txt\n\nant messages create --model claude-opus-4-8 --max-tokens 1024 \\\n --message '{role: user, content: [\n {type: document, source: {type: base64, media_type: application/pdf, data: \"@./scan.pdf\"}},\n {type: text, text: \"Extract the text from this scanned document.\"}\n ]}' \\\n --transform 'content.0.text' -r\n```\n\nFlags that natively take a file path (e.g. `--file` on `beta:files upload`) accept a bare path without `@`.\n\n## Version-controlled Managed Agents resources\n\nThis is the recommended flow for defining agents and environments — check the YAML into your repo and sync via `create` (first time) / `update` (thereafter). See `shared/managed-agents-core.md` for the field reference.\n\n```yaml\n# summarizer.agent.yaml\nname: Summarizer\nmodel: claude-sonnet-5\nsystem: |\n You are a helpful assistant that writes concise summaries.\ntools:\n - type: agent_toolset_20260401\n```\n\n```sh\n# Create (once) — capture the ID\nAGENT_ID=$(ant beta:agents create < summarizer.agent.yaml --transform id -r)\n\n# Update (CI) — needs ID + current version (optimistic lock)\nant beta:agents update --agent-id \"$AGENT_ID\" --version 1 < summarizer.agent.yaml\n```\n\nSame pattern for environments (`ant beta:environments create|update < env.yaml`), then start a session with both IDs:\n\n```sh\nant beta:sessions create --agent \"$AGENT_ID\" --environment-id \"$ENV_ID\" --title \"Task\"\nant beta:sessions:events send --session-id \"$SID\" \\\n --event '{type: user.message, content: [{type: text, text: \"Summarize X\"}]}'\nant beta:sessions:events list --session-id \"$SID\" --transform 'content.0.text' -r\nant beta:sessions:events stream --session-id \"$SID\" # live event stream\n```\n\n### Interactive session loop (stream-before-send)\n\n`ant beta:sessions:events stream` only delivers events emitted *after* the stream opens — so open it **before** sending the kickoff to avoid missing early events. Use process substitution to hold the stream on a file descriptor, send, then read:\n\n```sh\nexec {stream}< <(ant beta:sessions:events stream --session-id \"$SID\" \\\n --transform '{type,text:content.#(type==\"text\").text,err:error.message}' --format yaml)\n\nant beta:sessions:events send --session-id \"$SID\" > /dev/null <<'YAML'\nevents:\n - type: user.message\n content:\n - type: text\n text: Summarize the repo README\nYAML\n\ntype=\nwhile IFS= read -r -u \"$stream\" line; do\n case \"$line\" in\n type:\\ session.status_idle) break ;;\n type:\\ session.error)\n IFS= read -r -u \"$stream\" next || next=\n case \"$next\" in err:\\ *) msg=${next#err: } ;; *) msg=unknown ;; esac\n printf '\\n[Error: %s]\\n' \"$msg\"; break ;;\n type:\\ *) type=${line#type: } ;;\n text:*)\n [[ $type == agent.message ]] || continue\n val=${line#text: }\n case \"$val\" in '|-'|'|') ;; *) printf '%s' \"$val\" ;; esac ;;\n \\ \\ *)\n if [[ $type == agent.message ]]; then printf '%s\\n' \"${line# }\"; fi ;;\n esac\ndone\nexec {stream}<&-\n```\n\nThis works for interactive exploration and demos. For application code that needs to react to `agent.tool_use` / `agent.custom_tool_use` events, reconnect after drops, or dedup against `events.list`, use the SDK — see `shared/managed-agents-client-patterns.md`.\n\n## Scripting patterns\n\n`--transform id -r` on a list endpoint emits one bare ID per line — compose with `xargs`, or use `--max-items N` to bound the result set without piping through `head`:\n\n```sh\nFIRST=$(ant beta:agents list --transform id -r --max-items 1)\nant beta:agents:versions list --agent-id \"$FIRST\" --transform '{version,created_at}' --format jsonl\n```\n\nError shaping mirrors the success path (note: `-r` does not apply to error output — use `--format-error yaml` for an unquoted scalar here):\n\n```sh\nant beta:agents retrieve --agent-id bogus --transform-error error.message --format-error yaml 2>&1\n```\n\nShell completion: `ant @completion {zsh|bash|fish|powershell}`.\n\nFor the full, always-current reference (including per-endpoint flags), WebFetch the **Anthropic CLI** URL in `shared/live-sources.md`.\n</doc>\n\n<doc path=\"shared/claude-platform-on-aws.md\">\n# Claude Platform on AWS\n\n**Anthropic-operated** access to the Claude Developer Platform through AWS infrastructure — SigV4 authentication, AWS IAM access control, and AWS Marketplace billing. Because Anthropic operates it, **the API surface matches first-party with same-day parity** — for per-feature exceptions, see `shared/platform-availability.md` (the single source of truth; do not rely on an inline exception list here). Model IDs are the bare first-party strings (`claude-opus-4-8`, `claude-sonnet-5`) — **no provider prefix**.\n\n> **Not the same as Amazon Bedrock.** Bedrock is partner-operated (AWS runs the service; release schedules vary, feature subset, `anthropic.`-prefixed model IDs). Claude Platform on AWS and Bedrock coexist; pick by whether you need AWS-native IAM/billing with full Anthropic API parity (this page) vs. Bedrock's own ecosystem.\n\n---\n\n## Client & install\n\n| Language | Install | Client |\n|---|---|---|\n| Python | `pip install -U \"anthropic[aws]\"` | `from anthropic import AnthropicAWS` → `AnthropicAWS()` |\n| TypeScript | `npm install @anthropic-ai/aws-sdk` | `import AnthropicAws from \"@anthropic-ai/aws-sdk\"` → `new AnthropicAws()` |\n| Go | `go get github.com/anthropics/anthropic-sdk-go` | `import anthropicaws \"github.com/anthropics/anthropic-sdk-go/aws\"` → `anthropicaws.NewClient(ctx, anthropicaws.ClientConfig{})` |\n| C# | `dotnet add package Anthropic.Aws` | `new AnthropicAwsClient()` |\n| Java | See SDK repo in `shared/live-sources.md` | See SDK repo in `shared/live-sources.md` |\n| Ruby | `gem install anthropic aws-sdk-core` | See SDK repo in `shared/live-sources.md` |\n| PHP | `composer require anthropic-ai/sdk aws/aws-sdk-php` | See SDK repo in `shared/live-sources.md` |\n\nAfter construction, **use the client exactly as you would `Anthropic()`** — `client.messages.create(...)`, `client.beta.sessions.*`, etc., with bare model IDs.\n\n```python\nfrom anthropic import AnthropicAWS\n\nclient = AnthropicAWS() # region + workspace_id from env; see below\nclient.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=1024,\n messages=[{\"role\": \"user\", \"content\": \"Hello\"}],\n)\n```\n\n---\n\n## Required configuration\n\nTwo values must be available (constructor args or environment) — **there is no default fallback** for either:\n\n| Value | Env var | Notes |\n|---|---|---|\n| AWS region | `AWS_REGION` | Required. Unlike `AnthropicBedrock`, there is no `us-east-1` fallback. |\n| Workspace ID | `ANTHROPIC_AWS_WORKSPACE_ID` | Required. Routes requests to your Claude workspace. |\n\nEndpoint pattern: `https://aws-external-anthropic.{region}.api.aws/v1/...`. Requests are SigV4-signed with service name `aws-external-anthropic`.\n\n## Authentication\n\nThe client resolves AWS credentials via the standard precedence chain: explicit constructor args → environment (`AWS_ACCESS_KEY_ID`/`AWS_SECRET_ACCESS_KEY`/`AWS_SESSION_TOKEN`) → shared profile → assumed role / instance metadata.\n\n**Short-term API keys** are also supported for cases where SigV4 isn't practical (e.g., browser, simple scripts). Mint one with the per-language token-generator package; pass it as `api_key` on the client. Lifetime is the **lesser of** the requested duration, the underlying credential's expiry, and **12 hours**. For package names and IAM details, WebFetch the Claude Platform on AWS page in `shared/live-sources.md`.\n\n---\n\n## What to tell users\n\n- Treat it as first-party: every section of this skill applies unchanged. Do **not** apply Bedrock's feature-availability mask.\n- Model IDs are bare (`claude-opus-4-8`). Do **not** add an `anthropic.` prefix.\n- A missing region or `workspace_id` throws at client-construction time (no request is sent). A **403** means the request reached the server — check for a **wrong** `workspace_id` or a missing IAM action on the principal. See the IAM actions reference in `shared/live-sources.md`.\n</doc>\n\n<doc path=\"shared/error-codes.md\">\n# HTTP Error Codes Reference\n\nThis file documents HTTP error codes returned by the Claude API, their common causes, and how to handle them. For language-specific error handling examples, see the `python/` or `typescript/` folders.\n\n## Error Code Summary\n\n| Code | Error Type | Retryable | Common Cause |\n| ---- | ----------------------- | --------- | ------------------------------------ |\n| 400 | `invalid_request_error` | No | Invalid request format or parameters |\n| 401 | `authentication_error` | No | Invalid or missing API key |\n| 403 | `permission_error` | No | API key lacks permission |\n| 404 | `not_found_error` | No | Invalid endpoint or model ID |\n| 413 | `request_too_large` | No | Request exceeds size limits |\n| 429 | `rate_limit_error` | Yes | Too many requests |\n| 500 | `api_error` | Yes | Anthropic service issue |\n| 529 | `overloaded_error` | Yes | API is temporarily overloaded |\n\n## Detailed Error Information\n\n### 400 Bad Request\n\n**Causes:**\n\n- Malformed JSON in request body\n- Missing required parameters (`model`, `max_tokens`, `messages`)\n- Invalid parameter types (e.g., string where integer expected)\n- Empty messages array\n- Messages not alternating user/assistant\n\n**Example error:**\n\n```json\n{\n \"type\": \"error\",\n \"error\": {\n \"type\": \"invalid_request_error\",\n \"message\": \"messages: roles must alternate between \\\"user\\\" and \\\"assistant\\\"\"\n },\n \"request_id\": \"req_011CSHoEeqs5C35K2UUqR7Fy\"\n}\n```\n\n**Fix:** Validate request structure before sending. Check that:\n\n- `model` is a valid model ID\n- `max_tokens` is a positive integer\n- `messages` array is non-empty and alternates correctly\n\n---\n\n### 401 Unauthorized\n\n**Causes:**\n\n- Missing `x-api-key` header or `Authorization` header\n- Invalid API key format\n- Revoked or deleted API key\n- OAuth bearer token sent via `x-api-key` instead of `Authorization: Bearer`\n- Both `ANTHROPIC_API_KEY` and `ANTHROPIC_AUTH_TOKEN` set — the SDK sends both headers and the API rejects the request\n\n**Fix:** Set `ANTHROPIC_API_KEY`, or run `ant auth login` and leave the client constructor empty. For raw HTTP with an OAuth token, use `Authorization: Bearer <token>` (not `x-api-key:`).\n\n---\n\n### 403 Forbidden\n\n**Causes:**\n\n- API key doesn't have access to the requested model\n- Organization-level restrictions\n- Attempting to access beta features without beta access\n\n**Fix:** Check your API key permissions in the Console. You may need a different API key or to request access to specific features.\n\n---\n\n### 404 Not Found\n\n**Causes:**\n\n- Typo in model ID (e.g., `claude-sonnet-4.6` instead of `claude-sonnet-4-6`)\n- Using deprecated model ID\n- Invalid API endpoint\n\n**Fix:** Use exact model IDs from the models documentation. You can use aliases (e.g., `claude-opus-4-8`).\n\n---\n\n### 413 Request Too Large\n\n**Causes:**\n\n- Request body exceeds maximum size\n- Too many tokens in input\n- Image data too large\n\n**Fix:** Reduce input size — truncate conversation history, compress/resize images, or split large documents into chunks.\n\n---\n\n### 400 Validation Errors\n\nSome 400 errors are specifically related to parameter validation:\n\n- `max_tokens` exceeds model's limit\n- Invalid `temperature` value (must be 0.0-1.0)\n- `budget_tokens` >= `max_tokens` in extended thinking\n- Invalid tool definition schema\n\n**Model-specific 400s on Fable 5 / Opus 4.8 / 4.7:**\n\n- `temperature`, `top_p`, `top_k` are removed — sending any of them returns 400. Delete the parameter; see `shared/model-migration.md` → Per-SDK Syntax Reference.\n- `thinking: {type: \"enabled\", budget_tokens: N}` is removed — sending it returns 400. Use `thinking: {type: \"adaptive\"}` instead.\n- **Fable 5 only:** an explicit `thinking: {type: \"disabled\"}` returns 400 (it is accepted on Opus 4.8/4.7). Omit the `thinking` param entirely instead.\n- **Fable 5 only:** if the organization is set to zero data retention (ZDR) — or any retention below the required 30 days — then **all** Fable 5 requests return `400 invalid_request_error`, even with a perfectly valid payload. Check the org's retention configuration before debugging the request body.\n\n**Common mistake with extended thinking on older models (Opus 4.6 and earlier):**\n\n```\n# Wrong: budget_tokens must be < max_tokens\nthinking: budget_tokens=10000, max_tokens=1000 → Error!\n\n# Correct\nthinking: budget_tokens=10000, max_tokens=16000\n```\n\n---\n\n### 429 Rate Limited\n\n**Causes:**\n\n- Exceeded requests per minute (RPM)\n- Exceeded tokens per minute (TPM)\n- Exceeded tokens per day (TPD)\n\n**Headers to check:**\n\n- `retry-after`: Seconds to wait before retrying\n- `x-ratelimit-limit-*`: Your limits\n- `x-ratelimit-remaining-*`: Remaining quota\n\n**Fix:** The Anthropic SDKs automatically retry 429 and 5xx errors with exponential backoff (default: `max_retries=2`). For custom retry behavior, see the language-specific error handling examples.\n\n---\n\n### 500 Internal Server Error\n\n**Causes:**\n\n- Temporary Anthropic service issue\n- Bug in API processing\n\n**Fix:** Retry with exponential backoff. If persistent, check [status.anthropic.com](https://status.anthropic.com).\n\n---\n\n### 529 Overloaded\n\n**Causes:**\n\n- High API demand\n- Service capacity reached\n\n**Fix:** Retry with exponential backoff. Consider using a different model (Haiku is often less loaded), spreading requests over time, or implementing request queuing.\n\n---\n\n## Common Mistakes and Fixes\n\n| Mistake | Error | Fix |\n| ------------------------------- | ---------------- | ------------------------------------------------------- |\n| `temperature`/`top_p`/`top_k` on Fable 5 / Opus 4.8 / 4.7 | 400 | Remove the parameter (see `shared/model-migration.md`) |\n| `budget_tokens` on Fable 5 / Opus 4.8 / 4.7 | 400 | Use `thinking: {type: \"adaptive\"}` |\n| `thinking: {type: \"disabled\"}` on Fable 5 | 400 | Omit the `thinking` param entirely (accepted on Opus 4.8/4.7) |\n| Org set to ZDR / retention below 30 days (Fable 5) | 400 on every request | Fix the org's data-retention configuration — the payload isn't the problem |\n| `budget_tokens` >= `max_tokens` (older models) | 400 | Ensure `budget_tokens` < `max_tokens` |\n| Typo in model ID | 404 | Use valid model ID like `claude-opus-4-8` |\n| First message is `assistant` | 400 | First message must be `user` |\n| Consecutive same-role messages | 400 | Alternate `user` and `assistant` |\n| API key in code | 401 (leaked key) | Use environment variable |\n| Custom retry needs | 429/5xx | SDK retries automatically; customize with `max_retries` |\n\n## Typed Exceptions in SDKs\n\n**Always use the SDK's typed exception classes** instead of checking error messages with string matching. Each HTTP status code maps to a specific exception class per SDK.\n\n### Exception class names by language\n\n| HTTP | Python (`anthropic.*`) / TypeScript (`Anthropic.*`) | Ruby (`Anthropic::Errors::*`) | Java (`com.anthropic.errors.*`) | C# | PHP (`Anthropic\\Core\\Exceptions\\*`) |\n|---|---|---|---|---|---|\n| 400 | `BadRequestError` | `BadRequestError` | `BadRequestException` | `AnthropicBadRequestException` | `BadRequestException` |\n| 401 | `AuthenticationError` | `AuthenticationError` | `UnauthorizedException` | `AnthropicUnauthorizedException` | `AuthenticationException` |\n| 403 | `PermissionDeniedError` | `PermissionDeniedError` | `PermissionDeniedException` | `AnthropicForbiddenException` | `PermissionDeniedException` |\n| 404 | `NotFoundError` | `NotFoundError` | `NotFoundException` | `AnthropicNotFoundException` | `NotFoundException` |\n| 422 | `UnprocessableEntityError` | `UnprocessableEntityError` | `UnprocessableEntityException` | `AnthropicUnprocessableEntityException` | `UnprocessableEntityException` |\n| 429 | `RateLimitError` | `RateLimitError` | `RateLimitException` | `AnthropicRateLimitException` | `RateLimitException` |\n| ≥500 | `InternalServerError` | `InternalServerError` | `InternalServerException` | `Anthropic5xxException` | `InternalServerException` |\n| net | `APIConnectionError` | `APIConnectionError` | `AnthropicIoException` | `AnthropicIOException` | `APIConnectionException` |\n| base | `APIError` (both); `APIStatusError` (Python only) | `APIStatusError` / `APIError` | `AnthropicServiceException` | `AnthropicApiException` | `APIStatusException` / `APIException` |\n\nThe Ruby and PHP classes live in a dedicated errors namespace — write `Anthropic::Errors::RateLimitError` and `Anthropic\\Core\\Exceptions\\RateLimitException` (not bare `Anthropic::RateLimitError`). All 4xx C# exceptions also inherit from `Anthropic4xxException`.\n\n### Catch most-specific first, in a chain\n\nOrder `catch`/`except`/`rescue` clauses from the most specific subclass to the base class, with a separate clause for each category you handle differently — retryable (429, ≥500, network) vs. non-retryable (4xx). The SDK defines a distinct class per status for exactly this reason; a single broad catch-all discards that information.\n\n```python\ntry:\n msg = client.messages.create(...)\nexcept anthropic.NotFoundError as e: # 404 — e.g. bad model ID\n ...\nexcept anthropic.RateLimitError as e: # 429 — back off and retry\n ...\nexcept anthropic.APIStatusError as e: # any other non-2xx HTTP response\n print(e.status_code, e.message)\nexcept anthropic.APIConnectionError as e: # network failure before a response\n ...\n```\n\nThe same chain shape applies in every SDK: TypeScript `instanceof Anthropic.NotFoundError` → `RateLimitError` → `APIConnectionError` → `APIError` (check `APIConnectionError` before `APIError` — in the TypeScript SDK it's a subclass of `APIError`, unlike Python where it's a sibling); Ruby `rescue Anthropic::Errors::NotFoundError` → `…::RateLimitError` → `…::APIStatusError`; Java `catch (NotFoundException) … catch (RateLimitException) … catch (AnthropicServiceException)`; C# `catch (AnthropicNotFoundException) … catch (AnthropicRateLimitException) … catch (AnthropicApiException)`; PHP `catch (NotFoundException) … catch (RateLimitException) … catch (APIStatusException)`.\n\n### Go — `errors.As` then branch on status\n\nThe Go SDK returns a single `*anthropic.Error` for all non-2xx responses. Unwrap it with `errors.As`, then branch on `StatusCode`:\n\n```go\n_, err := client.Messages.New(ctx, params)\nif err != nil {\n var apierr *anthropic.Error\n if errors.As(err, &apierr) {\n switch apierr.StatusCode {\n case 404:\n // bad model ID / resource\n case 429:\n // back off and retry\n default:\n // other API error — apierr.StatusCode, apierr.RequestID\n }\n } else {\n // transport-level error (*url.Error wrapping *net.OpError, etc.)\n }\n}\n```\n\n### Error `.type` Field\n\nAll `APIStatusError` subclasses now expose a `.type` property (Python: `.type`, TypeScript: `.type`, Java: `.errorType()`, Go: `.Type()`, Ruby: `.type`, PHP: `.type`) that returns the API error type string (e.g., `\"invalid_request_error\"`, `\"authentication_error\"`, `\"rate_limit_error\"`, `\"overloaded_error\"`). Use this for programmatic error classification when you need finer granularity than the HTTP status code — for example, distinguishing `\"billing_error\"` from `\"permission_error\"` (both map to 403).\n\n```python\nexcept anthropic.APIStatusError as e:\n if e.type == \"rate_limit_error\":\n # handle rate limiting\n elif e.type == \"overloaded_error\":\n # handle overload\n```\n</doc>\n\n<doc path=\"shared/live-sources.md\">\n# Live Documentation Sources\n\nThis file contains WebFetch URLs for fetching current information from platform.claude.com and Agent SDK repositories.

terminal access to the Claude API. Every API resource is exposed as a subcommand. It is one convenient way to create agents, environments, sessions, and other resources from version-controlled YAML, and to inspect responses interactively.\n\n| Topic | URL | Extraction Prompt |\n| ------------- | ------------------------------------------------------- | -------------------------------------------------------------------------------------------------- |\n| Anthropic CLI | `https://platform.claude.com/docs/en/api/sdks/cli.md` | \"Extract CLI install, authentication, command structure, and the beta:agents/environments/sessions commands\" |\n| Authentication overview | `https://platform.claude.com/docs/en/manage-claude/authentication.md` | \"Extract the credential options (API keys, interactive OAuth login, Workload Identity Federation) and when to use each\" |\n| WIF reference | `https://platform.claude.com/docs/en/manage-claude/wif-reference.md` | \"Extract credential precedence order, the profile configuration file schema, and the configuration directory layout\" |\n\n---\n\n## Claude API SDK Repositories\n\nWebFetch these when a binding (class, method, namespace, field) isn't covered in the cached `{lang}/` skill files or in the managed-agents docs above. The SDKs include beta managed-agents support for `/v1/agents`, `/v1/sessions`, `/v1/environments`, and related resources — search the repo for `BetaManagedAgents`, `beta.agents`, `beta.sessions`, or the equivalent namespace for that language.\n\n| SDK | URL | Extraction Prompt |\n| ---------- | -------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- |\n| Python | `https://github.com/anthropics/anthropic-sdk-python` | \"Extract beta managed-agents namespaces, classes, and method signatures (`client.beta.agents`, `client.beta.sessions`)\" |\n| TypeScript | `https://github.com/anthropics/anthropic-sdk-typescript` | \"Extract beta managed-agents namespaces, classes, and method signatures (`client.beta.agents`, `client.beta.sessions`)\" |\n| Java | `https://github.com/anthropics/anthropic-sdk-java` | \"Extract beta managed-agents classes, builders, and method signatures (`client.beta().agents()`, `BetaManagedAgents*`)\" |\n| Go | `https://github.com/anthropics/anthropic-sdk-go` | \"Extract beta managed-agents types and method signatures (`client.Beta.Agents`, `BetaManagedAgents*` event types)\" |\n| Ruby | `https://github.com/anthropics/anthropic-sdk-ruby` | \"Extract beta managed-agents methods and parameter shapes (`client.beta.agents`, `client.beta.sessions`)\" |\n| C# | `https://github.com/anthropics/anthropic-sdk-csharp` | \"Extract beta managed-agents classes and method signatures (NuGet package, `BetaManagedAgents*` types)\" |\n| PHP | `https://github.com/anthropics/anthropic-sdk-php` | \"Extract beta managed-agents classes and method signatures (`$client->beta->agents`, `BetaManagedAgents*` params)\" |\n\nEach SDK repo also ships runnable programs under `examples/` — including the refusal-fallback / `fallbacks` examples (client-side middleware registration, fallback state, server-side `fallbacks` param). Fetch those for exact per-language syntax instead of translating another language's example.\n\n---\n\n## Fallback Strategy\n\nIf WebFetch fails (network issues, URL changed):\n\n1. Use cached content from the language-specific files (note the cache date)\n2. Inform user the data may be outdated\n3. Suggest they check platform.claude.com or the GitHub repos directly\n</doc>\n\n<doc path=\"shared/managed-agents-api-reference.md\">\n# Managed Agents — Endpoint Reference\n\nAll endpoints require `x-api-key` and `anthropic-version: 2023-06-01` headers. Managed Agents endpoints additionally require the `anthropic-beta` header.\n\n## Beta Headers\n\n```\nanthropic-beta: managed-agents-2026-04-01\n```\n\nThe SDK adds this header automatically for all `client.beta.{agents,environments,sessions,vaults,memory_stores,deployments,deployment_runs}.*` calls. Skills endpoints use `skills-2025-10-02`; Files endpoints use `files-api-2025-04-14`.\n\n---\n\n## SDK Method Reference\n\nAll resources are under the `beta` namespace. Python and TypeScript share identical method names.\n\n| Resource | Python / TypeScript (`client.beta.*`) | Go (`client.Beta.*`) |\n| --- | --- | --- |\n| Agents | `agents.create` / `retrieve` / `update` / `list` / `archive` | `Agents.New` / `Get` / `Update` / `List` / `Archive` |\n| Agent Versions | `agents.versions.list` | `Agents.Versions.List` |\n| Environments | `environments.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `Environments.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |\n| Environment Work (self-hosted) | `environments.work.poller` / `stats` / `stop` | See `shared/managed-agents-self-hosted-sandboxes.md` |\n| Sessions | `sessions.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `Sessions.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |\n| Session Events | `sessions.events.list` / `send` / `stream` | `Sessions.Events.List` / `Send` / `StreamEvents` |\n| Session Threads | `sessions.threads.list` / `retrieve` / `archive`; `sessions.threads.events.list` / `stream` | `Sessions.Threads.List` / `Get` / `Archive`; `Sessions.Threads.Events.List` / `StreamEvents` |\n| Session Resources | `sessions.resources.add` / `retrieve` / `update` / `list` / `delete` | `Sessions.Resources.Add` / `Get` / `Update` / `List` / `Delete` |\n| Deployments | `deployments.create` / `pause` / `unpause` / `archive` / `run` | Not yet documented — WebFetch the SDK repo (`shared/live-sources.md`) |\n| Deployment Runs | `deployment_runs.list` / `retrieve` (TS: `deploymentRuns.*`) | Not yet documented — WebFetch the SDK repo (`shared/live-sources.md`) |\n| Vaults | `vaults.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `Vaults.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |\n| Credentials | `vaults.credentials.create` / `retrieve` / `update` / `list` / `delete` / `archive` / `mcp_oauth_validate` | `Vaults.Credentials.New` / `Get` / `Update` / `List` / `Delete` / `Archive` / `McpOauthValidate` |\n| Memory Stores | `memory_stores.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `MemoryStores.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |\n| Memories | `memory_stores.memories.create` / `retrieve` / `update` / `list` / `delete` | `MemoryStores.Memories.New` / `Get` / `Update` / `List` / `Delete` |\n| Memory Versions | `memory_stores.memory_versions.list` / `retrieve` / `redact` | `MemoryStores.MemoryVersions.List` / `Get` / `Redact` |\n\n**Naming quirks to watch for:**\n- Agents and Session Threads have **no delete** — only `archive`. Archive is **permanent**: the agent becomes read-only, new sessions cannot reference it, and there is no unarchive. Confirm with the user before archiving a production agent. Environments, Sessions, Vaults, Credentials, and Memory Stores have both `delete` and `archive`; Session Resources, Files, Skills, and Memories are `delete`-only; Memory Versions have neither — only `redact`.\n- Session resources use `add` (not `create`).\n- Go's event stream is `StreamEvents` (not `Stream`).\n- The self-hosted worker is **not** under `client.beta.*` — it's `EnvironmentWorker` from `anthropic.lib.environments` / `@anthropic-ai/sdk/helpers/beta/environments`; only `environments.work.poller/stats/stop` are client methods.\n\n**Agent shorthand:** `agent` on session create accepts three forms — a bare string (`agent=\"agent_abc123\"`, latest version), a pinned reference `{type: \"agent\", id, version}`, or `{type: \"agent_with_overrides\", id, version?, model?, system?, tools?, mcp_servers?, skills?}` to override those fields for this session only (see `shared/managed-agents-core.md` → Override agent configuration for a session).\n\n**Model shorthand:** `model` on agent create accepts either a bare string (`model=\"claude-opus-4-8\"` — uses `standard` speed) or the full config object (`{id: \"claude-opus-4-8\", speed: \"fast\"}`). Note: `speed: \"fast\"` is supported only on Opus 4.8 and Opus 4.7. Opus 4.7 fast mode is deprecated; after removal, `speed: \"fast\"` on Opus 4.7 returns an error. Opus 4.8 is the durable fast-capable tier.\n\n---\n\n## Agents\n\n**Step one of every flow.** Sessions require a pre-created agent — there is no inline agent config under `managed-agents-2026-04-01`.\n\n| Method | Path | Operation | Description |\n| -------- | ------------------------------------------------ | ---------------- | ---------------------------------------- |\n| `GET` | `/v1/agents` | ListAgents | List agents |\n| `POST` | `/v1/agents` | CreateAgent | Create a saved agent configuration |\n| `GET` | `/v1/agents/{agent_id}` | GetAgent | Get agent details |\n| `POST` | `/v1/agents/{agent_id}` | UpdateAgent | Update agent configuration |\n| `POST` | `/v1/agents/{agent_id}/archive` | ArchiveAgent | Archive an agent.

See `shared/managed-agents-scheduled-deployments.md` for the conceptual guide (cron/DST semantics, failure behavior, lifecycle).\n\n| Method | Path | Operation | Description |\n| -------- | ------------------------------------------------ | ---------------- | ---------------------------------------- |\n| `POST` | `/v1/deployments` | CreateDeployment | Create a scheduled deployment |\n| `POST` | `/v1/deployments/{deployment_id}/pause` | PauseDeployment | Suppress scheduled triggers (reversible; manual runs still allowed) |\n| `POST` | `/v1/deployments/{deployment_id}/unpause` | UnpauseDeployment | Resume from the next occurrence (no backfill) |\n| `POST` | `/v1/deployments/{deployment_id}/archive` | ArchiveDeployment | **Terminal** — schedule stops, deployment becomes immutable |\n| `POST` | `/v1/deployments/{deployment_id}/run` | RunDeployment | Trigger a manual run immediately (`trigger_context.type: \"manual\"`); works while paused |\n\n## Deployment Runs\n\nEach trigger attempt (scheduled or manual) writes a `deployment_run` record (`drun_` IDs) carrying either the created `session_id` or an `error.type` (`environment_archived`, `agent_archived`, `vault_not_found`, `session_rate_limited`, `service_unavailable`).\n\n| Method | Path | Operation | Description |\n| -------- | ------------------------------------------------ | ---------------- | ---------------------------------------- |\n| `GET` | `/v1/deployment_runs?deployment_id=...` | ListDeploymentRuns | List runs for a deployment (paginated; filter failures with `has_error=true`) |\n| `GET` | `/v1/deployment_runs/{deployment_run_id}` | GetDeploymentRun | Retrieve a single run by ID (a `deployment_run.*` webhook event carries this as `data.id`) |\n\n## Vaults\n\nVaults store credentials that Anthropic manages on your behalf — MCP credentials (OAuth with auto-refresh, or static bearer tokens) and `environment_variable` credentials substituted into outbound requests at egress. Attach to sessions via `vault_ids`. See `managed-agents-tools.md` §Vaults for the conceptual guide and credential shapes.\n\n| Method | Path | Operation | Description |\n| -------- | ------------------------------------------------ | ---------------- | ---------------------------------------- |\n| `POST` | `/v1/vaults` | CreateVault | Create a vault |\n| `GET` | `/v1/vaults` | ListVaults | List vaults |\n| `GET` | `/v1/vaults/{vault_id}` | GetVault | Get vault details |\n| `POST` | `/v1/vaults/{vault_id}` | UpdateVault | Update vault |\n| `DELETE` | `/v1/vaults/{vault_id}` | DeleteVault | Delete vault |\n| `POST` | `/v1/vaults/{vault_id}/archive` | ArchiveVault | Archive vault |\n\n## Credentials\n\nCredentials are individual secrets stored inside a vault.\n\n| Method | Path | Operation | Description |\n| -------- | ----------------------------------------------------------------- | ------------------ | ---------------------------- |\n| `POST` | `/v1/vaults/{vault_id}/credentials` | CreateCredential | Create a credential |\n| `GET` | `/v1/vaults/{vault_id}/credentials` | ListCredentials | List credentials in vault |\n| `GET` | `/v1/vaults/{vault_id}/credentials/{credential_id}` | GetCredential | Get credential metadata |\n| `POST` | `/v1/vaults/{vault_id}/credentials/{credential_id}` | UpdateCredential | Update credential |\n| `DELETE` | `/v1/vaults/{vault_id}/credentials/{credential_id}` | DeleteCredential | Delete credential |\n| `POST` | `/v1/vaults/{vault_id}/credentials/{credential_id}/archive` | ArchiveCredential | Archive credential |\n| `POST` | `/v1/vaults/{vault_id}/credentials/{credential_id}/mcp_oauth_validate` | McpOauthValidate | Validate an MCP OAuth credential |\n\n## Memory Stores\n\nWorkspace-scoped persistent memory that survives across sessions. Attach to a session via a `{\"type\": \"memory_store\", \"memory_store_id\": ...}` entry in `resources[]` (session-create time only). See `shared/managed-agents-memory.md` for the conceptual guide, the FUSE-mount agent interface, preconditions, and versioning.\n\n| Method | Path | Operation | Description |\n| -------- | ------------------------------------------------ | ------------------ | ---------------------------------------- |\n| `POST` | `/v1/memory_stores` | CreateMemoryStore | Create a store (`name`, `description`, `metadata`) |\n| `GET` | `/v1/memory_stores` | ListMemoryStores | List stores (`include_archived`, `created_at_{gte,lte}`) |\n| `GET` | `/v1/memory_stores/{memory_store_id}` | GetMemoryStore | Get store details |\n| `POST` | `/v1/memory_stores/{memory_store_id}` | UpdateMemoryStore | Update store |\n| `DELETE` | `/v1/memory_stores/{memory_store_id}` | DeleteMemoryStore | Delete store |\n| `POST` | `/v1/memory_stores/{memory_store_id}/archive` | ArchiveMemoryStore | Archive store. Makes it **read-only**; existing sessions continue, new sessions cannot reference it. No unarchive. |\n\n## Memories\n\nIndividual text documents inside a store (≤ 100KB each). `create` creates at a `path` and returns `409` (`memory_path_conflict_error`, with `conflicting_memory_id`) if the path is occupied; `update` mutates by `mem_...` ID (rename and/or content). Only `update` accepts a `precondition` (`{\"type\": \"content_sha256\", \"content_sha256\": ...}`) — on mismatch returns `409` (`memory_precondition_failed_error`). List endpoints accept `view: \"basic\"|\"full\"` (controls whether `content` is populated; `retrieve` defaults to `full`).\n\n| Method | Path | Operation | Description |\n| -------- | ----------------------------------------------------------------- | -------------- | ---------------------------------------- |\n| `GET` | `/v1/memory_stores/{memory_store_id}/memories` | ListMemories | Returns `Memory \\| MemoryPrefix`;

Outside the overrides form, those fields live on the agent, not here.\n>\n> **`checkout`** accepts `{type: \"branch\", name: \"...\"}` or `{type: \"commit\", sha: \"...\"}`. Omit for the repo's default branch.\n\n### CreateEnvironment Request Body\n\n```json\n{\n \"name\": \"string (required)\",\n \"description\": \"string (optional)\",\n \"config\": {\n \"type\": \"cloud | self_hosted\",\n \"networking\": {\n \"type\": \"unrestricted | limited (union — see SDK types)\"\n },\n \"packages\": { }\n },\n \"metadata\": { \"key\": \"value\" }\n}\n```\n\n### CreateDeployment Request Body\n\n```json\n{\n \"name\": \"Weekly compliance scan\",\n \"agent\": \"agent_abc123 (required — same shapes as CreateSession)\",\n \"environment_id\": \"env_abc123 (required)\",\n \"initial_events\": [\n { \"type\": \"user.message\", \"content\": [{ \"type\": \"text\", \"text\": \"Run the weekly compliance scan.\" }] }\n ],\n \"schedule\": {\n \"type\": \"cron\",\n \"expression\": \"0 20 * * 5\",\n \"timezone\": \"America/New_York\"\n }\n}\n```\n\n> Optional session config (`resources`, `vault_ids`, etc.) is supported the same way as on CreateSession. Response includes `status`, `paused_reason`, and `schedule.upcoming_runs_at` (next fire times). See `shared/managed-agents-scheduled-deployments.md`.\n\n### SendEvents Request Body\n\n```json\n{\n \"events\": [\n {\n \"type\": \"user.message\",\n \"content\": [\n {\n \"type\": \"text\",\n \"text\": \"Hello\"\n }\n ]\n }\n ]\n}\n```\n\n> `system.message` events (update the system prompt between turns) use the same envelope with `type: \"system.message\"` — Claude Opus 4.8 only; see `shared/managed-agents-events.md` § Updating the system prompt mid-session.\n\n### Define Outcome Event\n\n```json\n{\n \"type\": \"user.define_outcome\",\n \"description\": \"Build a DCF model for Costco in .xlsx\",\n \"rubric\": { \"type\": \"file\", \"file_id\": \"file_01...\" },\n \"max_iterations\": 5\n}\n```\n\n> `rubric` is required: `{type: \"text\", content}` or `{type: \"file\", file_id}`. `max_iterations` default 3, max 20. Echoed back with `outcome_id` + `processed_at`. See `shared/managed-agents-outcomes.md`.\n\n### Tool Result Event\n\n```json\n{\n \"type\": \"user.custom_tool_result\",\n \"custom_tool_use_id\": \"sevt_abc123\",\n \"content\": [{ \"type\": \"text\", \"text\": \"Result data\" }],\n \"is_error\": false\n}\n```\n\n---\n\n## Error Handling\n\nManaged Agents endpoints use the standard Anthropic API error format. Errors are returned with an HTTP status code and a JSON body containing `type`, `error`, and `request_id`:\n\n```json\n{\n \"type\": \"error\",\n \"error\": {\n \"type\": \"invalid_request_error\",\n \"message\": \"Description of what went wrong\"\n },\n \"request_id\": \"req_011CRv1W3XQ8XpFikNYG7RnE\"\n}\n```\n\nInclude the `request_id` when reporting issues to Anthropic — it lets us trace the request end-to-end. The inner `error.type` is one of the following:\n\n| Status | Error type | Description |\n|---|---|---|\n| 400 | `invalid_request_error` | The request was malformed or missing required parameters |\n| 401 | `authentication_error` | Invalid or missing API key |\n| 403 | `permission_error` | The API key doesn't have permission for this operation |\n| 404 | `not_found_error` | The requested resource doesn't exist |\n| 409 | `invalid_request_error` | The request conflicts with the resource's current state (e.g., sending to an archived session) |\n| 413 | `request_too_large` | The request body exceeds the maximum allowed size |\n| 429 | `rate_limit_error` | Too many requests — check rate limit headers for retry timing |\n| 500 | `api_error` | An internal server error occurred |\n| 529 | `overloaded_error` | The service is temporarily overloaded — retry with backoff |\n\nNote that `409 Conflict` carries `error.type: \"invalid_request_error\"` (there is no separate `conflict_error` type); inspect both the HTTP status and the `message` to distinguish conflicts from other invalid requests.\n\n---\n\n## Pagination\n\nMost Managed Agents list endpoints use the `page` / `next_page` cursor scheme:\n\n| Field | Where | Notes |\n|---|---|---|\n| `limit` | query | Max items per page |\n| `page` | query | Opaque cursor from a previous response — pass a `next_page` or `prev_page` value here |\n| `order` | query | `asc` / `desc` on endpoints that support sorting. A cursor encodes the `order` of the request that produced it — reusing it with a different `order` returns 400. Other params (filters, `limit`) can change between paginated requests. |\n| `next_page` | response | Cursor for the next page; `null` when there are no more results |\n| `prev_page` | response | Cursor for the previous page on endpoints that support backward pagination — currently **only `GET /v1/sessions`**. `null` on the first page. On endpoints that don't support it, the field is **absent** (not `null`). |\n\nEvery SDK exposes an auto-paginating iterator that follows `next_page`. In Python and TypeScript, iterate the list result directly; the other SDKs expose the iterator via a separate method (iterating the plain list result returns one page). SDK auto-pagination is **forward-only** — to go back a page, read `prev_page` from the response and pass it back as the `page` parameter yourself.\n\n> ⚠️ Some endpoints use a **different** cursor scheme: Message Batches, Files, Models, and several Admin API endpoints take `after_id`/`before_id` and return `has_more`/`first_id`/`last_id` instead of `page`/`next_page`. Some `page`-scheme endpoints (e.g. `GET /v1/skills`) also return a `has_more` boolean alongside `next_page`. Check the endpoint's reference page for its exact pagination fields.\n\n---\n\n## Rate Limits\n\nManaged Agents endpoints have per-organization request-per-minute (RPM) limits, separate from your [Messages API token limits](https://platform.claude.com/docs/en/api/rate-limits). Model inference inside a session still draws from your organization's standard ITPM/OTPM limits.\n\n| Endpoint group | Scope | RPM | Max concurrent |\n|---|---|---|---|\n| Create operations (Agents, Sessions, Vaults) | organization | 300 | — |\n| All other operations (Agents, Sessions, Vaults) | organization | 600 | — |\n| All operations (Environments) | organization | 60 | 5 |\n\nFiles and Skills endpoints use the standard tier-based [rate limits](https://platform.claude.com/docs/en/api/rate-limits).\n\nWhen a limit is exceeded the API returns `429` with a `rate_limit_error` (see [Error Handling](#error-handling) for the response envelope) and a `retry-after` header indicating how many seconds to wait before retrying. The Anthropic SDK reads this header and retries automatically.\n</doc>\n\n<doc path=\"shared/managed-agents-client-patterns.md\">\n# Managed Agents — Common Client Patterns\n\nPatterns you'll write on the client side when driving a Managed Agent session, grounded in working SDK examples.\n\nCode samples are TypeScript — other languages follow the same shape; see `{lang}/managed-agents/README.md` (cURL and C#: `curl/managed-agents.md`) for equivalents.\n\n---\n\n## 1. Lossless stream reconnect\n\n**Problem:** SSE has no replay. If the connection drops mid-session, a naive reconnect re-opens the stream from \"now\" and you silently miss every event emitted in between.\n\n**Solution:** on reconnect, fetch the full event history via `events.list()` *before* consuming the live stream, and dedupe on event ID as the live stream catches up.\n\n```ts\nconst seenEventIds = new Set<string>()\nconst stream = await client.beta.sessions.events.stream(session.id)\n\n// Stream is now open and buffering server-side. Read history first.\nfor await (const event of client.beta.sessions.events.list(session.id)) {\n seenEventIds.add(event.id)\n handle(event)\n}\n\n// Tail the live stream. Dedupe only gates handle() — terminal checks must run\n// even for already-seen events, or a terminal event that was in the history\n// response gets skipped by `continue` and the loop never exits.\nfor await (const event of stream) {\n if (!seenEventIds.has(event.id)) {\n seenEventIds.add(event.id)\n handle(event)\n }\n if (event.type === 'session.status_terminated') break\n if (event.type === 'session.status_idle' && event.stop_reason.type !== 'requires_action') break\n}\n```\n\n---\n\n## 2. `processed_at` — queued vs processed\n\nEvery event on the stream carries `processed_at` (ISO 8601). For client-sent events (`user.message`, `user.interrupt`, `user.tool_confirmation`, `user.custom_tool_result`) it's `null` when the event has been queued but not yet picked up by the agent, and populated once the agent processes it. The same event appears on the stream twice — once with `processed_at: null`, once with a timestamp.\n\n```ts\nfor await (const event of stream) {\n if (event.type === 'user.message') {\n if (event.processed_at == null) onQueued(event.id)\n else onProcessed(event.id, event.processed_at)\n }\n}\n```\n\nUse this to drive pending → acknowledged UI state for anything you send. How you map a locally-rendered optimistic message to the server-assigned `event.id` is application-specific (typically via the return value of `events.send()` or FIFO ordering).\n\n---\n\n## 3. Interrupt a running session\n\nSend `user.interrupt` as a normal event. The session keeps running until it reaches a safe boundary, then goes idle.\n\n```ts\nawait client.beta.sessions.events.send(session.id, {\n events: [{ type: 'user.interrupt' }],\n})\n\n// Drain until the session is truly done — see Pattern 5 for the full gate.\nfor await (const event of stream) {\n if (event.type === 'session.status_terminated') break\n if (\n event.type === 'session.status_idle' &&\n event.stop_reason.type !== 'requires_action'\n ) break\n}\n```\n\nReference: `interrupt.ts` — sends the interrupt the moment it sees `span.model_request_start`, drains to idle, then verifies via `sessions.retrieve()`.\n\n---\n\n## 4. `tool_confirmation` round-trip\n\nWhen the agent has `permission_policy: { type: 'always_ask' }`, any call to that tool fires an `agent.tool_use` event with `evaluated_permission === 'ask'` and the session goes idle waiting for a decision. Respond with `user.tool_confirmation`.\n\n```ts\nfor await (const event of stream) {\n if (event.type === 'agent.tool_use' && event.evaluated_permission === 'ask') {\n await client.beta.sessions.events.send(session.id, {\n events: [{\n type: 'user.tool_confirmation',\n tool_use_id: event.id, // not a toolu_ id — use event.id\n result: 'allow', // or 'deny'\n // deny_message: '...', // optional, only with result: 'deny'\n }],\n })\n }\n}\n```\n\nKey points:\n- `tool_use_id` is `event.id` (typically `sevt_...`), **not** a `toolu_...` ID.\n- `result` is `'allow' | 'deny'`. Use `deny_message` to tell the model *why* you denied — it gets surfaced back to the agent.\n- Multiple pending tools: respond once per `agent.tool_use` event with `evaluated_permission === 'ask'`.\n\nReference: `tool-permissions.ts`.\n\n---\n\n## 5. Correct idle-break gate\n\nDo not break on `session.status_idle` alone. The session goes idle transiently — e.g. between parallel tool executions, while waiting for a `user.tool_confirmation`, or while awaiting a `user.custom_tool_result`. Break when idle with a terminal `stop_reason`, or on `session.status_terminated`.\n\n```ts\nfor await (const event of stream) {\n handle(event)\n if (event.type === 'session.status_terminated') break\n if (event.type === 'session.status_idle') {\n if (event.stop_reason.type === 'requires_action') continue // waiting on you — handle it\n break // end_turn or retries_exhausted — both terminal\n }\n}\n```\n\n`stop_reason.type` values on `session.status_idle`:\n- `requires_action` — agent is waiting on a client-side event (tool confirmation, custom tool result). Handle it, don't break.\n- `retries_exhausted` — terminal failure. Break, then check `sessions.retrieve()` for the error state.\n- `end_turn` — normal completion.\n\n---\n\n## 6. Post-idle status-write race\n\nThe SSE stream emits `session.status_idle` slightly before the session's queryable status reflects it. Clients that break on idle and immediately call `sessions.delete()` or `sessions.archive()` will intermittently 400 with \"cannot delete/archive while running.\"\n\nPoll before cleanup:\n\n```ts\nlet s\nfor (let i = 0; i < 10; i++) {\n s = await client.beta.sessions.retrieve(session.id)\n if (s.status !== 'running') break\n await new Promise(r => setTimeout(r, 200))\n}\nif (s?.status !== 'running') {\n await client.beta.sessions.archive(session.id)\n} // else: still running after 2s — don't archive, let it settle or escalate\n```\n\n---\n\n## 7. Stream-first, then send\n\nAlways open the stream **before** sending the kickoff event. Otherwise the agent may process the event and emit the first events before your consumer is attached, and you'll miss them.\n\n```ts\nconst stream = await client.beta.sessions.events.stream(session.id)\nawait client.beta.sessions.events.send(session.id, {\n events: [{ type: 'user.message', content: [{ type: 'text', text: 'Hello' }] }],\n})\nfor await (const event of stream) { /* ... */ }\n```\n\nThe `Promise.all([stream, send])` shape works too, but stream-first is simpler and has the same effect — the stream starts buffering the moment it's opened.\n\n---\n\n## 8. File-mount gotchas\n\n**The mounted resource has a different `file_id` than the file you uploaded.** Session creation makes a session-scoped copy.\n\n```ts\nconst uploaded = await client.beta.files.upload({ file, purpose: 'agent_resource' })\n// uploaded.id → the original file\nconst session = await client.beta.sessions.create({\n /* ... */\n resources: [{ type: 'file', file_id: uploaded.id, mount_path: '/workspace/data.csv' }],\n})\n// session.resources[0].file_id !== uploaded.id ← different IDs\n```\n\nDelete the original via `files.delete(uploaded.id)`; the session-scoped copy is garbage-collected with the session. `mount_path` must be absolute — see `shared/managed-agents-environments.md`.\n\n---\n\n## 9. Secrets for non-MCP APIs and CLIs — keep them host-side via custom tools\n\n**Problem:** you want the agent to call a third-party API or run a CLI that needs a secret (API key, token, service-account credential), but you can't or don't want to hand the secret to a vault.\n\n**First check:** for cloud environments, the first-class answer is now a vault `environment_variable` credential — the agent's shell sees an opaque placeholder and the real secret is substituted at egress. See `shared/managed-agents-tools.md` → Vaults. Use this pattern instead when that doesn't fit: **self-hosted sandboxes** (env-var credentials not yet supported there), clients that reject the placeholder via local format validation, secrets that must never leave your infrastructure, or calls that need host-side binaries.\n\n**Solution:** move the authenticated call to your side. Declare a custom tool on the agent; when the agent emits `agent.custom_tool_use`, your orchestrator (the process reading the SSE stream) executes the call with its own credentials and responds with `user.custom_tool_result`. The container never sees the key.\n\n```ts\n// Agent template: declare the tool, no credentials\ntools: [{ type: 'custom', name: 'linear_graphql', input_schema: { /* query, vars */ } }]\n\n// Orchestrator: handle the call with host-side creds\nfor await (const event of stream) {\n if (event.type === 'agent.custom_tool_use' && event.name === 'linear_graphql') {\n const result = await linear.request(event.input.query, event.input.vars) // host's key\n await client.beta.sessions.events.send(session.id, {\n events: [{ type: 'user.custom_tool_result', tool_use_id: event.id, result }],\n })\n }\n}\n```\n\nSame shape works for `gh` CLI, local eval scripts, or anything else that needs host-side auth or binaries.\n\n**Security note:** this does not expose a public endpoint. `agent.custom_tool_use` arrives on the SSE stream your orchestrator already holds open with your Anthropic API key, and `user.custom_tool_result` goes back via `events.send()` under the same key. Your orchestrator is a client, not a server — nothing unauthenticated is listening.\n\n**Do not embed API keys in the system prompt or user messages as a workaround.** Prompts and messages are stored in the session's event history, returned by `events.list()`, and included in compaction summaries — a secret placed there is durably persisted and readable via the API for the life of the session.\n</doc>\n\n<doc path=\"shared/managed-agents-core.md\">\n# Managed Agents — Core Concepts\n\n## Architecture\n\nManaged Agents is built around four core concepts:\n\n| Concept | Endpoint | What it is |\n|---|---|---|\n| **Agent** | `/v1/agents` | A persisted, versioned object defining the agent's capabilities and persona: model, system prompt, tools, MCP servers, skills. **Must be created before starting a session.** See the Agents section below. |\n| **Session** | `/v1/sessions` | A stateful interaction with an agent. References a pre-created agent by ID + an environment + initial instructions. Produces an event stream. |\n| **Environment** | `/v1/environments` | A template defining the configuration for container provisioning. |\n| **Container** | N/A | An isolated compute instance where the agent's **tools** execute (bash, file ops, code). The agent loop does not run here — it runs on Anthropic's orchestration layer and acts on the container via tool calls. |\n\n```\n ┌─────────────────────────────────────┐\n │ Anthropic orchestration layer │\nAgent (config) ───────▶│ (agent loop: Claude + tool calls) │\n └──────────────┬──────────────────────┘\n │ tool calls\n ▼\nEnvironment (template) ──▶ Container (tool execution workspace)\n │\n Session ─┤\n ├── Resources (files, repos, memory stores — attached at startup)\n ├── Vault IDs (MCP credential references)\n └── Conversation (event stream in/out)\n```\n\n> **Agent creation is a prerequisite.** Sessions reference a pre-created agent by ID — `model`/`system`/`tools` live on the agent object, never on the session. Every flow starts with `POST /v1/agents`.\n\n---\n\n## Session Lifecycle\n\n```\nrescheduling → running ↔ idle → terminated\n```\n\n| Status | Description |\n| -------------- | ------------------------------------------------------------------ |\n| `idle` | Agent has finished the current task, and is awaiting input. It's either waiting for input to continue working via a `user.message` or blocked awaiting a `user.custom_tool_result` or `user.tool_confirmation`. The `stop_reason` attached contains more information about why the Agent has stopped working. |\n| `running` | Session has starting running, and the Agent is actively doing work. |\n| `rescheduling` | Session is (re)scheduling after a retryable error has occurred, ready to be picked up by the orchestration system. |\n| `terminated` | Session has terminated, entering an irreversible and unusable state. |\n\n- Events can be sent when the session is `running` or `idle`. Messages are queued and processed in order.\n- The agent transitions `idle → running` when it receives a new event, then back to `idle` when done.\n- Errors surface as `session.error` events in the stream, not as a status value.\n\nEvery session has a live trace view in the Anthropic Console at `https://platform.claude.com/workspaces/default/sessions/{session_id}`. Print this URL immediately after creating a session so the user can watch tool calls and messages stream in real time. The `default` workspace segment auto-resolves to the session's actual workspace on load, so you don't need the workspace id.\n\n### Built-in session features\n\n- **Context compaction** — if you approach max context, the API automatically condenses session history to keep the interaction going\n- **Prompt caching** — historical repeated tokens are cached, reducing processing time and cost\n- **Extended thinking** — on by default, returned as `agent.thinking` events\n\n### Session operations\n\n| Operation | Notes |\n|---|---|\n| List / fetch | Paginated list or single resource by ID |\n| Update | Only `title` is updatable |\n| Archive | Session becomes **read-only**. Not reversible. |\n| Delete | Permanently deletes session, event history, container, and checkpoints. |\n\nThese are ops/inspection calls — typically made from a terminal, not application code. From the shell (see `shared/anthropic-cli.md`):\n\n```sh\nant beta:sessions list --transform '{id,title,status,created_at}' --format jsonl\nant beta:sessions retrieve --session-id \"$SID\"\nant beta:sessions:events stream --session-id \"$SID\" # watch events live\nant beta:sessions archive --session-id \"$SID\"\nant beta:sessions delete --session-id \"$SID\"\n```\n\n---\n\n## Sessions\n\nA session is a running agent instance inside an environment.\n\n### Session Object\n\nKey fields returned by the API:\n\n| Field | Type | Description |\n| --------------- | -------- | --------------------------------------------------- |\n| `type` | string | Always `\"session\"` |\n| `id` | string | Unique session ID |\n| `title` | string | Human-readable title |\n| `status` | string | `idle`, `running`, `rescheduling`, `terminated` |\n| `created_at` | string | ISO 8601 timestamp |\n| `updated_at` | string | ISO 8601 timestamp |\n| `archived_at` | string | ISO 8601 timestamp (nullable) |\n| `environment_id` | string | Environment ID |\n| `agent` | object | Agent configuration |\n| `resources` | array | Attached files, repos, and memory stores |\n| `metadata` | object | User-provided key-value pairs (max 8 keys) |\n| `usage` | object | Token usage statistics |\n\n### Creating a session\n\n**A session is meaningless without an agent.** Sessions reference a pre-created agent by ID. Create the agent first via `agents.create()`, then reference it:\n\n```ts\n// 1. Create the agent (reusable, versioned)\nconst agent = await client.beta.agents.create(\n {\n name: \"Coding Assistant\",\n model: \"claude-opus-4-8\",\n system: \"You are a helpful coding agent.\",\n tools: [{ type: \"agent_toolset_20260401\"}],\n },\n);\n\n// 2. Start a session that references it\nconst session = await client.beta.sessions.create(\n {\n agent: agent.id, // string shorthand → latest version. Or: { type: \"agent\", id: agent.id, version: agent.version }\n environment_id: environmentId,\n title: \"Hello World Session\",\n },\n);\n```\n\n> 💡 **Watch it live in Console.** While developing, print a link so you can click through to the session UI instead of parsing the event stream: `https://platform.claude.com/workspaces/default/sessions/{session.id}`. The `default` workspace segment auto-resolves to the session's actual workspace on load, so you don't need to know the workspace id. Include this `print`/`console.log` in code you generate for users who are iterating locally.\n\n**Session creation parameters:**\n\n| Field | Type | Required | Description |\n| --------------- | -------- | -------- | ---------------------------------------------- |\n| `agent` | string or object | **Yes** | Three forms: string shorthand `\"agent_abc123\"` (latest version); pinned `{type: \"agent\", id, version}`; or `{type: \"agent_with_overrides\", id, version?, ...}` to override `model`/`system`/`tools`/`mcp_servers`/`skills` for this session only — see § Override agent configuration for a session |\n| `environment_id`| string | **Yes** | Environment ID |\n| `title` | string | No | Human-readable name (appears in logs/dashboards) |\n| `resources` | array | No | Files, GitHub repos, or memory stores, attached to the container at startup. Memory stores are session-create-only (not addable via `resources.add()`). |\n| `vault_ids` | array | No | Vault IDs (`vlt_*`) — MCP credentials with auto-refresh + `environment_variable` secrets substituted at egress. See `shared/managed-agents-tools.md` → Vaults. |\n| `metadata` | object | No | User-provided key-value pairs |\n\n**Agent configuration fields** (passed to `agents.create()`, not `sessions.create()`):\n\n| Field | Type | Required | Description |\n| ------------- | -------- | -------- | ---------------------------------------------- |\n| `name` | string | **Yes** | Human-readable name (1-256 chars) |\n| `model` | string or object | **Yes** | Claude model ID (bare string, or `{id, speed}` object). All Claude 4.5+ models supported. |\n| `system` | string | No | System prompt — defines the agent's behavior (up to 100K chars) |\n| `tools` | array | No | Encompasses three kinds: (1) pre-built Claude Agent tools (`agent_toolset_20260401`), (2) MCP tools (`mcp_toolset`), and (3) custom client-side tools. Max 128. |\n| `mcp_servers` | array | No | MCP server connections — standardized third-party capabilities (e.g. GitHub, Asana). Max 20, unique names. See `shared/managed-agents-tools.md` → MCP Servers. |\n| `skills` | array | No | Customized \"best-practices\" context with progressive disclosure. Max 20. See `shared/managed-agents-tools.md` → Skills. |\n| `description` | string | No | Description of the agent (up to 2048 chars) |\n| `multiagent` | object | No | `{type: \"coordinator\", agents: [...]}` — roster this agent may delegate to. See `shared/managed-agents-multiagent.md`. |\n| `metadata` | object | No | Arbitrary key-value pairs (max 16, keys ≤64 chars, values ≤512 chars) |\n\n---\n\n## Agents\n\n**This is where every Managed Agents flow begins.** The agent object is a persisted, versioned configuration — you create it once, then reference it by ID every time you start a session. No agent → no session.\n\n### Agent Object\n\nThe API is **flat** — `model`, `system`, `tools` etc. are top-level fields, not wrapped in an `agent:{}` sub-object.\n\n| Field | Type | Required | Description |\n| ------------------ | -------- | -------- | -------------------------------------------------- |\n| `name` | string | Yes | Human-readable name |\n| `model` | string | Yes | Claude model ID |\n| `system` | string | No | System prompt |\n| `tools` | array | No | Agent toolset / MCP toolset / custom tools |\n| `mcp_servers` | array | No | MCP server connections |\n| `skills` | array | No | Skill references (max 20) |\n| `description` | string | No | Description of the agent |\n| `multiagent` | object | No | Coordinator roster — see `shared/managed-agents-multiagent.md` |\n| `metadata` | object | No | Arbitrary key-value pairs |\n\n### Lifecycle: create once, run many, update in place\n\nThe agent is a **persistent resource**, not a per-run parameter. The intended pattern:\n\n```\n┌─ setup (once) ─────────┐ ┌─ runtime (every invocation) ─┐\n│ agents.create() │ │ sessions.create( │\n│ → store agent_id │ ──→ │ agent={type:..., id: ID} │\n│ in config/env/db │ │ ) │\n└────────────────────────┘ └──────────────────────────────┘\n```\n\n**Anti-pattern:** calling `agents.create()` at the top of every script run. This accumulates orphaned agent objects, pays create latency on every invocation, and defeats the versioning model. If you see `agents.create()` in a function that's called per-request or per-cron-tick, that's wrong — hoist it to one-time setup and persist the ID.\n\n> **Recommended — define agents and environments as YAML + apply via the `ant` CLI.** The split is **CLI for the control plane, SDK for the data plane**: agents and environments are relatively static resources you manage with `ant` (version-controlled YAML, applied from CI); sessions are dynamic and driven by your application through the SDK. See `shared/anthropic-cli.md` → *Version-controlled Managed Agents resources* for the `ant beta:agents create < agent.yaml` / `update --version N` flow. The SDK `agents.create()` call shown elsewhere in this doc is the in-code equivalent — use it when you need to provision programmatically, but prefer the YAML flow for anything a human maintains.\n\n### Versioning\n\nEach `POST /v1/agents/{id}` (update) creates a new immutable version (numeric timestamp, e.g. `1772585501101368014`). The agent's history is append-only — you can't edit a past version.\n\n**Why version:**\n- **Reproducibility** — pin a session to a known-good config: `{type: \"agent\", id, version: 3}`\n- **Safe iteration** — update the agent without breaking sessions already running on the old version\n- **Rollback** — if a new system prompt regresses, pin new sessions back to the prior version while you debug\n\n**`version` is optional.** Omit it (or use the string shorthand `agent=\"agent_abc123\"`) to get the latest version at session-creation time. Pass it explicitly (`{type: \"agent\", id, version: N}`) to pin for reproducibility.\n\n**Getting the version to pin:** `agents.create()` and `agents.update()` both return `version` in the response. Store it alongside `agent_id`. To fetch the current latest for an existing agent: `GET /v1/agents/{id}` → `.version`.\n\n**When to update vs create new:** Update (`POST /v1/agents/{id}`) when it's conceptually the same agent with tweaked behavior (better prompt, extra tool). Create a new agent when it's a different persona/purpose. Rule of thumb: if you'd give it the same `name`, update.\n\n### Agent Endpoints\n\n| Operation | Method | Path |\n| ---------------- | -------- | ------------------------------------- |\n| Create | `POST` | `/v1/agents` |\n| List | `GET` | `/v1/agents` |\n| Get | `GET` | `/v1/agents/{id}` |\n| Update | `POST` | `/v1/agents/{id}` |\n| Archive | `POST` | `/v1/agents/{id}/archive` |\n\n> ⚠️ **Archive is permanent.** Archiving makes the agent read-only: existing sessions continue to run, but **new sessions cannot reference it**, and there is no unarchive. Since agents have no `delete`, this is the terminal lifecycle state. Never archive a production agent as routine cleanup — confirm with the user first.\n\n### Using an Agent in a Session\n\nReference the agent by string ID (latest version) or by object with an explicit version:\n\n```python\n# String shorthand — uses the agent's latest version\nsession = client.beta.sessions.create(\n agent=agent.id,\n environment_id=environment_id,\n)\n\n# Or pin to a specific version (int)\nsession = client.beta.sessions.create(\n agent={\"type\": \"agent\", \"id\": agent.id, \"version\": agent.version},\n environment_id=environment_id,\n)\n```\n\n### Override agent configuration for a session\n\nThe third `agent` form, `agent_with_overrides`, replaces parts of the agent's configuration for **a single session** — try a different model or grant an extra tool without versioning the agent. Pass `id` (and optionally `version`; omitted = latest, same default as the other two forms) plus any of `model`, `system`, `tools`, `mcp_servers`, `skills`:\n\n```python\nsession = client.beta.sessions.create(\n agent={\n \"type\": \"agent_with_overrides\",\n \"id\": agent.id,\n \"model\": \"claude-opus-4-8\", # replace the agent's model for this session\n \"system\": None, # clear the system prompt for this session\n },\n environment_id=environment_id,\n)\n```\n\nEach overridable field follows tri-state rules:\n- **Omit** → the session inherits the value from the referenced agent version.\n- **`null` (or `[]` for list fields)** → the session runs with that field cleared. Applies in full to `system`, `mcp_servers`, `skills`. Two exceptions: `model` is never clearable (`model: null` → 400 `agent_model_required`); clearing `tools` returns 400 when the session's effective `skills` is non-empty (skills require the `read` tool), otherwise `tools: null` / `tools: []` clears.\n- **A value** → replaces the agent's value **in full**. Overrides never merge — a `tools` override must list every tool the session should have.\n\nOverrides are session-local: they do **not** modify the agent resource or create a new agent version. The response's `agent` object reflects the post-override configuration, while its `id` and `version` still identify the base agent — so you can trace a session back to its base. In multiagent sessions, overrides apply to the coordinator and its `{type: \"self\"}` copies; roster agents referenced by ID always use their own as-created configuration (see `shared/managed-agents-multiagent.md`).\n\n### Updating the agent configuration mid-session\n\n`sessions.update()` can change `agent.tools`, `agent.mcp_servers` (including permission policies), and `vault_ids` on an **existing** session. This is a **session-local override** — it does not create a new agent version and does not propagate back to the agent object. The provided arrays are **full replacements**; to append one tool, `GET` the session, modify, and `POST` back. The session must be `idle` — interrupt first if running.\n\nOnly `tools` and `mcp_servers` can change after a session is created — to run with a `model`, `system`, or `skills` other than the agent's values, use `agent_with_overrides` at create time (above). The agent's configured `system` field is fixed for the session's lifetime; you can still **replace the effective system prompt between turns** by sending a `system.message` event (see `shared/managed-agents-events.md` § Updating the system prompt mid-session).\n\n```python\nclient.beta.sessions.update(\n session.id,\n agent={\n \"tools\": [\n {\"type\": \"agent_toolset_20260401\"},\n {\"type\": \"mcp_toolset\", \"mcp_server_name\": \"linear\"},\n ],\n \"mcp_servers\": [{\"type\": \"url\", \"name\": \"linear\", \"url\": \"https://mcp.linear.app/sse\"}],\n },\n vault_ids=[\"vlt_...\"],\n)\n```\n</doc>\n\n<doc path=\"shared/managed-agents-environments.md\">\n# Managed Agents — Environments & Resources\n\n## Environments\n\nCreating a session requires an `environment_id`. Environments are **reusable configuration templates** for spinning up containers in Anthropic's infrastructure — you might create different environments for different use cases (e.g. data visualization vs web development, with different package sets). Anthropic handles scaling, container lifecycle, and work orchestration.\n\n**Environment names must be unique.** Creating an environment with an existing name returns 409.\n\n### Networking\n\n| Network Policy | Description |\n| ---------------- | ------------------------------------------------------------- |\n| `unrestricted` | Full egress (except legal blocklist) |\n| `limited` | Deny-by-default; opt in via `allowed_hosts` / `allow_package_managers` / `allow_mcp_servers` |\n\n```json\n{\n \"networking\": {\n \"type\": \"limited\",\n \"allow_package_managers\": true,\n \"allow_mcp_servers\": true,\n \"allowed_hosts\": [\"api.example.com\"]\n }\n}\n```\n\nAll three `limited` fields are optional. `allow_package_managers` (default `false`) permits PyPI/npm/etc.; `allow_mcp_servers` (default `false`) permits the agent's configured MCP server endpoints without listing them in `allowed_hosts`.\n\n**MCP caveat:** Under `limited` networking, either set `allow_mcp_servers: true` or add each MCP server domain to `allowed_hosts`. Otherwise the container can't reach them and tools silently fail.\n\n### Creating an environment\n\nThe SDK adds `managed-agents-2026-04-01` automatically. TypeScript:\n\n```ts\nconst env = await client.beta.environments.create({\n name: \"my_env\",\n config: {\n type: \"cloud\",\n networking: { type: \"unrestricted\" },\n },\n});\n```\n\n### Self-hosted sandboxes\n\nTo run tool execution in **your own infrastructure** instead of Anthropic's, set `config: {type: \"self_hosted\"}` — the agent loop stays on Anthropic's side, but `bash` / file ops / code execute in a container you control via an outbound-polling worker. The `networking` block does not apply (you control egress). Resource mounting (`file`, `github_repository`) and memory stores behave differently — see `shared/managed-agents-self-hosted-sandboxes.md` for the worker, credentials, and cloud-vs-self-hosted comparison.\n\n### Environment CRUD\n\n| Operation | Method | Path | Notes |\n| ---------------- | -------- | ------------------------------------------ | ----- |\n| Create | `POST` | `/v1/environments` | |\n| List | `GET` | `/v1/environments` | Paginated (`limit`, `after_id`, `before_id`) |\n| Get | `GET` | `/v1/environments/{id}` | |\n| Update | `POST` | `/v1/environments/{id}` | Changes apply only to **new** containers; existing sessions keep their original config |\n| Delete | `DELETE` | `/v1/environments/{id}` | Returns 204. |\n| Archive | `POST` | `/v1/environments/{id}/archive` | Makes it **read-only**; existing sessions continue, new sessions cannot reference it. No unarchive — terminal state. |\n\n---\n\n## Resources\n\nAttach files, GitHub repositories, and memory stores to a session. **Session creation blocks until all resources are mounted** — the container won't go `running` until every file and repo is in place. Max **999 file resources** per session. Multiple GitHub repositories per session are supported. For `type: \"memory_store\"` resources (persistent cross-session memory — max 8 per session), see `shared/managed-agents-memory.md`.\n\n### File Uploads (input — host → agent)\n\nUpload a file first via the Files API, then reference by `file_id` + `mount_path`:\n\n```ts\n// 1. Upload\nconst file = await client.beta.files.upload({\n file: fs.createReadStream(\"data.csv\"),\n purpose: \"agent\",\n});\n\n// 2. Attach as a session resource\nconst session = await client.beta.sessions.create({\n agent: agent.id,\n environment_id: envId,\n resources: [\n { type: \"file\", file_id: file.id, mount_path: \"/workspace/data.csv\" }\n ],\n});\n```\n\n**`mount_path` is required** and must be absolute. Parent directories are created automatically. Agent working directory defaults to `/workspace`. Files are mounted read-only — the agent writes modified versions to new paths.\n\n### Session outputs (output — agent → host)\n\nThe agent can write files to `/mnt/session/outputs/` during a session. These are automatically captured by the Files API and can be listed and downloaded afterwards:\n\n```ts\n// After the turn completes, list output files scoped to this session:\nfor await (const f of client.beta.files.list({\n scope_id: session.id,\n betas: [\"managed-agents-2026-04-01\"],\n})) {\n console.log(f.filename, f.size_bytes);\n const resp = await client.beta.files.download(f.id);\n const text = await resp.text();\n}\n```\n\n**Requirements:**\n- The `write` tool (or `bash`) must be enabled for the agent to create output files.\n- Session-scoped `files.list` / `files.download` captures outputs written to `/mnt/session/outputs/`.\n- The filter parameter is **`scope_id`** (REST query param `?scope_id=<session_id>`). The SDK's files resource auto-adds only the `files-api-2025-04-14` header, so pass `betas: [\"managed-agents-2026-04-01\"]` explicitly (or both headers on raw HTTP) — without it the API may reject `scope_id` as an unknown field. Requires `@anthropic-ai/sdk` ≥ 0.88.0 / `anthropic` (Python) ≥ 0.92.0 — older versions don't type `scope_id`. The `ant` CLI does **not** expose this flag yet; use the SDK or curl.\n- Pass the session ID returned by `sessions.create()` verbatim (e.g. `sesn_011CZx...`) — the API validates the prefix.\n- There's a brief indexing lag (~1–3s) between `session.status_idle` and output files appearing in `files.list`. Retry once or twice if empty.\n\n> **Fallback when `scope_id` filtering is unavailable** (older SDK, or endpoint returns an error): send a follow-up `user.message` asking the agent to `read` each file under `/mnt/session/outputs/` and return the contents. The agent streams the file bodies back as `agent.message` text. This works for text files only and costs output tokens — use it to unblock, not as the primary path.\n\nThis gives you a bidirectional file bridge: upload reference data in, download agent artifacts out.\n\n### GitHub Repositories\n\nClones a GitHub repository into the session container during initialization, before the agent begins execution. The agent can read, edit, commit, and push via `bash` (`git`). Multiple repositories per session are supported — add one `resources` entry per repo. Repositories are cached, so future sessions that use the same repository start faster.\n\nRepositories are attached for the lifetime of the session — to change which repositories are mounted, create a new session. You **can** rotate a repository's `authorization_token` on a running session via `client.beta.sessions.resources.update(resource_id, {session_id, authorization_token})`; the resource `id` is returned at session creation and by `resources.list()`.\n\n**Fields:**\n\n| Field | Required | Notes |\n|---|---|---|\n| `type` | ✅ | `\"github_repository\"` |\n| `url` | ✅ | The GitHub repository URL |\n| `authorization_token` | ✅ | GitHub Personal Access Token with repository access. **Never echoed in API responses.** |\n| `mount_path` | ❌ | Path where the repository will be cloned. Defaults to `/workspace/<repo-name>`. |\n| `checkout` | ❌ | `{type: \"branch\", name: \"...\"}` or `{type: \"commit\", sha: \"...\"}`. Defaults to the repo's default branch. |\n\n**Token permission levels** (fine-grained PATs):\n- `Contents: Read` — clone only\n- `Contents: Read and write` — push changes and create pull requests\n\n**How auth works:** `authorization_token` is never placed inside the container. `git pull` / `git push` and GitHub REST calls against the attached repository are routed through an Anthropic-side git proxy that injects the token after the request leaves the sandbox. Code running in the container — including anything the agent writes — cannot read or exfiltrate it.\n\n> ‼️ **To generate pull requests** you also need GitHub **MCP server** access — the `github_repository` resource gives filesystem + git access only. See `shared/managed-agents-tools.md` → MCP Servers. The PR workflow is: edit files in the mounted repo → push branch via `bash` (authenticated via the git proxy using `authorization_token`) → create PR via the MCP `create_pull_request` tool (authenticated via the vault).\n\n**TypeScript:**\n\n```ts\n// 1. Create the agent — declare GitHub MCP (no auth here)\nconst agent = await client.beta.agents.create(\n {\n name: 'GitHub Agent',\n model: 'claude-opus-4-8',\n mcp_servers: [\n { type: 'url', name: 'github', url: 'https://api.githubcopilot.com/mcp/' },\n ],\n tools: [\n { type: 'agent_toolset_20260401', default_config: { enabled: true } },\n { type: 'mcp_toolset', mcp_server_name: 'github' },\n ],\n },\n);\n\n// 2.

Without the filter, you get all files uploaded to your account.\n</doc>\n\n<doc path=\"shared/managed-agents-events.md\">\n# Managed Agents — Events & Steering\n\n## Events\n\n### Sending Events\n\nSend events to a session via `POST /v1/sessions/{id}/events`.\n\n| Event Type | When to Send |\n| ------------------------- | --------------------------------------------------- |\n| `user.message` | Send a user message |\n| `user.interrupt` | Interrupt the agent while it's running |\n| `user.tool_confirmation` | Approve/deny a tool call (when `always_ask` policy) |\n| `user.custom_tool_result` | Provide result for a custom tool call |\n| `user.define_outcome` | Start a rubric-graded iterate loop — see `shared/managed-agents-outcomes.md` |\n| `system.message` | Update the agent's system prompt between turns — **Claude Opus 4.8 only**; see § Updating the system prompt mid-session |\n\n#### Updating the system prompt mid-session (`system.message`)\n\nUnlike the `system` field on the agent definition (fixed at session creation), a `system.message` event changes the system prompt **as the session progresses** — a different persona, revised constraints, or runtime-fetched context that should shape behavior going forward:\n\n```python\nclient.beta.sessions.events.send(\n session.id,\n events=[\n {\n \"type\": \"system.message\",\n \"content\": [\n {\"type\": \"text\", \"text\": \"The user's current timezone is America/New_York.\"},\n ],\n },\n ],\n)\n```\n\nConstraints:\n\n- **Claude Opus 4.8 only.** If any model configured on the agent does not support mid-conversation system injection, the event is rejected with a `model_does_not_support_mid_conversation_system` validation error.\n- **Cannot be sent while the session is idle with `stop_reason: requires_action`** (blocked on `user.custom_tool_result` / `user.tool_confirmation`).\n- `content` accepts 1–1000 text items.\n\n### Receiving Events\n\nThree methods:\n\n1. **Streaming (SSE)**: `GET /v1/sessions/{id}/events/stream` — real-time Server-Sent Events. **Long-lived** — the server sends periodic heartbeats to keep the connection alive.\n2. **Polling**: `GET /v1/sessions/{id}/events` — paginated event list (query params: `limit` default 1000, `page`). **Returns immediately** — this is a plain paginated GET, not a long-poll.\n3. **Webhooks**: Anthropic POSTs session state transitions to your HTTPS endpoint — thin payloads (IDs only), HMAC-signed, Console-registered. See `shared/managed-agents-webhooks.md`.\n\nAll **persisted** events carry `id`, `type`, and `processed_at` (ISO 8601; `null` if not yet processed by the agent). The stream-only `event_start` / `event_delta` preview events (see § Live previews) carry only the `id` of the event they preview.\n\n> ⚠️ **Robust polling (raw HTTP).** If you bypass the SDK and roll your own poll loop, don't rely on `requests` or `httpx` timeouts as wall-clock caps — they're **per-chunk** read timeouts, reset every time a byte arrives. A trickling response (heartbeats, a wedged chunked-encoding body, a misbehaving proxy) can keep the call blocked indefinitely even with `timeout=(5, 60)` or `httpx.Timeout(120)`. Neither library has a \"total wall-clock\" timeout built in. For a hard deadline: track `time.monotonic()` at the loop level and break/cancel if a single request exceeds your budget (e.g. via a watchdog thread, or `asyncio.wait_for()` around async httpx). **Prefer the SDK** — `client.beta.sessions.events.stream()` and `client.beta.sessions.events.list()` handle timeout + retry sanely.\n>\n> If `GET /v1/sessions/{id}/events` (paginated) ever hangs after headers, you've likely hit `GET /v1/sessions/{id}/events` by mistake or a server-side stall — report it; don't treat it as a client-config problem.\n\n### Event Types (Received)\n\nEvent types use dot notation, grouped by namespace:\n\n| Event Type | Description |\n| --- | --- |\n| `agent.message` | Agent text output |\n| `agent.thinking` | Extended thinking blocks |\n| `agent.tool_use` | Agent used a built-in tool (`agent_toolset_20260401`) |\n| `agent.tool_result` | Result from a built-in tool |\n| `agent.mcp_tool_use` | Agent used an MCP tool |\n| `agent.mcp_tool_result` | Result from an MCP tool |\n| `agent.custom_tool_use` | Agent invoked a custom tool — session goes idle, you respond with `user.custom_tool_result` |\n| `agent.thread_context_compacted` | Conversation context was compacted |\n| `session.status_idle` | Agent has finished the current task, and is awaiting input. It's either waiting for input to continue working via a `user.message` or blocked awaiting a `user.custom_tool_result` or `user.tool_confirmation`. The `stop_reason` attached contains more information about why the Agent has stopped working. |\n| `session.status_running` | Session has starting running, and the Agent is actively doing work. |\n| `session.status_rescheduled` | Session is (re)scheduling after a retryable error has occurred, ready to be picked up by the orchestration system. |\n| `session.status_terminated` | Session has terminated, entering an irreversible and unusable state. |\n| `session.error` | Error occurred during processing |\n| `span.model_request_start` | Model inference started |\n| `span.model_request_end` | Model inference completed |\n| `span.outcome_evaluation_start` / `_ongoing` / `_end` | Grader progress for outcome-oriented sessions — see `shared/managed-agents-outcomes.md` |\n| `session.thread_created` | Subagent thread spawned (multiagent) — see `shared/managed-agents-multiagent.md` |\n| `session.thread_status_running` / `_idle` / `_rescheduled` / `_terminated` | Subagent thread status transitions (multiagent). `_idle` carries `stop_reason`. |\n| `agent.thread_message_sent` / `_received` | Cross-thread message, carries `to_session_thread_id` / `from_session_thread_id` (multiagent) |\n\nThe stream also echoes back user-sent events (`user.message`, `user.interrupt`, `user.tool_confirmation`, `user.custom_tool_result`, `user.define_outcome`).\n\nStream-only delta preview events (`event_start`, `event_delta`) are the one exception to the `{domain}.{action}` naming convention — see § Live previews below; they never appear in `GET /v1/sessions/{id}/events`.\n\n---\n\n## Live previews\n\nBy default, assistant text reaches the stream as buffered `agent.message` events — emitted only after the model request that produced them finishes. **Live previews** let you render that text incrementally while the model is still generating. The buffered `agent.message` is always the authoritative record; a client that ignores previews still receives a complete, correct stream. The wire format is **not** Messages-API streaming: the delta type is `content_delta`, not `content_block_delta`, so Messages-API accumulator code does not carry over unchanged.\n\n**Opt in per stream connection** by adding the `event_deltas[]` query parameter to `GET /v1/sessions/{id}/events/stream`, repeated once per event type to preview. Accepted values: `agent.message`, `agent.thinking` (any other value → 400). Only the session-level stream supports it — per-thread streams (`/threads/{tid}/stream`) reject the parameter.\n\n```python\nstream = client.beta.sessions.events.stream(\n session_id=session.id,\n event_deltas=[\"agent.message\"],\n)\n```\n\nWhen a previewed event begins, the stream emits an `event_start` carrying the upcoming event's `type` and `id`; for `agent.message` it's followed by `event_delta` events carrying incremental text:\n\n```json\n{\"type\": \"event_start\", \"event\": {\"type\": \"agent.message\", \"id\": \"sevt_01abc...\"}}\n{\"type\": \"event_delta\", \"event_id\": \"sevt_01abc...\", \"delta\": {\"type\": \"content_delta\", \"index\": 0, \"content\": {\"type\": \"text\", \"text\": \"Here is the summary\"}}}\n```\n\n`event_start` and `event_delta` have no `id` or `processed_at` of their own — the only identifier they carry is the `id` of the event they preview. For `agent.thinking`, **only** the `event_start` is emitted (a \"thinking has started\" signal) — no deltas follow; read content from the buffered `agent.thinking` event.\n\n**Accumulate-and-reconcile pattern.** Treat the preview as a scratch buffer keyed by `(event_id, index)`. On `event_start`, create an empty entry for the announced `id`. On each `event_delta`, append `delta.content.text` to `(event_id, delta.index)` and render the running text. When the buffered `agent.message` arrives, match it by `id`, **discard the accumulated preview**, and render the message's content instead. The identifiers always line up: `event_start.event.id`, every `event_delta.event_id`, and the buffered event's `id` are the same value. On a normal turn the order is fixed: `session.status_running` → `span.model_request_start` → `event_start` → `event_delta`* → buffered `agent.message` → `span.model_request_end`. If the turn errors or is interrupted the buffered event may never arrive, but `span.model_request_end` still does — close any unreconciled preview when you see it. Python/TypeScript/Go SDKs ship an accumulator helper that implements this; in other SDKs apply the manual pattern to the generated event types.\n\n**Limitations:**\n- **Best effort** — under load the server may shed deltas for an event; you receive a contiguous prefix and then no further deltas for that event. The buffered `agent.message` still arrives complete. Never treat an accumulated preview as final.\n- **No replay on reconnect** — deltas are delivered only to the connection that opted in, while it's open. After a drop, follow the consolidation pattern in § Reconnecting after a dropped stream — the history fetch returns any buffered events emitted during the gap; missed deltas cannot be re-requested.\n- **Primary thread, text only** — tool use, tool results, MCP results, and subagent-thread activity are never previewed.\n- **Never persisted** — `event_start` / `event_delta` exist only on the live SSE stream, never in `GET /v1/sessions/{id}/events`.\n\n---\n\n## Steering Patterns\n\nPractical patterns for driving a session via the events surface.\n\n### Stream-first ordering\n\n**Open the stream before sending events.** The stream only delivers events that occur *after* it's opened — it does not replay current state or historical events. If you send a message first and open the stream second, early events (including fast status transitions) arrive buffered in a single batch and you lose the ability to react to them in real time.\n\n```ts\n// ✅ Correct — stream and send concurrently\nconst [response] = await Promise.all([\n streamEvents(sessionId), // opens SSE connection\n sendMessage(sessionId, text),\n]);\n\n// ❌ Wrong — events before stream opens arrive as a single buffered batch\nawait sendMessage(sessionId, text);\nconst response = await streamEvents(sessionId);\n```\n\n**For full history,** use `GET /v1/sessions/{id}/events` (paginated list) — the stream only gives you live events from connection onward.\n\n### Reconnecting after a dropped stream\n\n**The SSE stream has no replay.** If your connection drops (httpx read timeout, network blip) and you reconnect, you only get events emitted *after* reconnection. Any events emitted during the gap are lost from the stream.\n\n**The consolidation pattern:** on every (re)connect, overlap the stream with a history fetch and dedupe by event ID:\n\n```python\ndef connect_with_consolidation(client, session_id):\n # 1. Open the SSE stream first\n stream = client.beta.sessions.events.stream(session_id=session_id)\n\n # 2. Fetch history to cover any gap\n history = client.beta.sessions.events.list(\n session_id=session_id,\n )\n\n # 3. Yield history first, then stream — dedupe by event.id\n seen = set()\n for ev in history.data:\n seen.add(ev.id)\n yield ev\n for ev in stream:\n if ev.id not in seen:\n seen.add(ev.id)\n yield ev\n```\n\n### Message queuing\n\n**You don't have to wait for a response before sending the next message.** User events are queued server-side and processed in order. This is useful for chat bridges where the user sends rapid follow-ups:\n\n```ts\n// All three go into one session; agent processes them in order\nawait sendMessage(sessionId, \"Summarize the README\");\nawait sendMessage(sessionId, \"Actually also check the CONTRIBUTING guide\");\nawait sendMessage(sessionId, \"And compare the two\");\n// Stream once — agent responds to all three as a coherent turn\n```\n\nEvents can be sent up to the Session at any time. There is no need to wait on a specific session status to enqueue new events via `client.beta.sessions.events.send()`\n\n### Interrupt\n\nAn `interrupt` event **jumps the queue** (ahead of any pending user messages) and forces the session into `idle`. Use this for \"stop\" / \"nevermind\" / \"cancel\" commands:\n\n```ts\nawait client.beta.sessions.events.send(sessionId, {\n events: [{ type: 'interrupt' }],\n});\n```\n\nThe agent stops mid-task. It does not see the interrupt as a message — it just halts. Send a follow-up `user` event to explain what to do instead. If an outcome is active, the interrupt also marks `span.outcome_evaluation_end.result: \"interrupted\"` (see `shared/managed-agents-outcomes.md`).\n\n> **Note**: Interrupt events may have empty IDs in the current implementation. When troubleshooting, use the `processed_at` timestamp along with surrounding event IDs.\n\n### Event payloads\n\nsome events carry useful metadata beyond the status change itself:\n\n`session.status_idle` — includes a `stop_reason` field which elaborates on why the session stopped and what type of further action is required by the user.\n```json\n{\n \"id\": \"sevt_456\",\n \"processed_at\": \"2026-04-07T04:27:43.197Z\",\n \"stop_reason\": {\n \"event_ids\": [\n \"sevt_123\"\n ],\n \"type\": \"requires_action\"\n },\n \"type\": \"status_idle\"\n}\n```\n\n`span.model_request_end` contains a `model_usage` field for cost tracking and efficiency analysis:\n\n```json\n{\n \"type\": \"span.model_request_end\",\n \"id\": \"sevt_456\",\n \"is_error\": false,\n \"model_request_start_id\": \"sevt_123\",\n \"model_usage\": {\n \"cache_creation_input_tokens\": 0,\n \"cache_read_input_tokens\": 6656,\n \"input_tokens\": 3571,\n \"output_tokens\": 727\n },\n \"processed_at\": \"2026-04-07T04:11:32.189Z\"\n}\n```\n\n**`agent.thread_context_compacted`** — emitted when the conversation history was summarized to fit context. Includes `pre_compaction_tokens` so you know how much was squeezed:\n\n```json\n{\n \"id\": \"sevt_abc123\",\n \"processed_at\": \"2026-03-24T14:05:15.787Z\",\n \"type\": \"agent.thread_context_compacted\"\n}\n```\n\n### Archive\n\nWhen done with a session, archive it to free resources:\n\n```ts\nawait client.beta.sessions.archive(sessionId);\n```\n\n> Archiving a **session** is routine cleanup — sessions are per-run and disposable. **Do not generalize this to agents or environments**: those are persistent, reusable resources, and archiving them is permanent (no unarchive; new sessions cannot reference them). See `shared/managed-agents-overview.md` → Common Pitfalls.\n</doc>\n\n<doc path=\"shared/managed-agents-memory.md\">\n# Managed Agents — Memory Stores\n\n> **Public beta.** Memory stores ship under the `managed-agents-2026-04-01` beta header; the SDK sets it automatically on all `client.beta.memory_stores.*` calls. If `client.beta.memory_stores` is missing, upgrade to the latest SDK release.\n\nSessions are ephemeral by default — when one ends, anything the agent learned is gone. A **memory store** is a workspace-scoped collection of small text documents that persists across sessions. When a store is attached to a session (via `resources[]`), it is mounted into the container as a filesystem directory; the agent reads and writes it with the ordinary file tools, and a system-prompt note tells it the mount is there.\n\nEvery mutation to a memory produces an immutable **memory version** (`memver_...`), giving you an audit trail and point-in-time rollback/redact.\n\n## Object model\n\n| Object | ID prefix | Scope | Notes |\n| --- | --- | --- | --- |\n| Memory store | `memstore_...` | Workspace | Attach to sessions via `resources[]` |\n| Memory | `mem_...` | Store | One text file, addressed by `path` (≤ 100KB each — prefer many small files) |\n| Memory version | `memver_...` | Memory | Immutable snapshot per mutation; `operation` ∈ `created` / `modified` / `deleted` |\n\n## Create a store\n\n`description` is passed to the agent so it knows what the store contains — write it for the model, not for humans.\n\n```python\nstore = client.beta.memory_stores.create(\n name=\"User Preferences\",\n description=\"Per-user preferences and project context.\",\n)\nprint(store.id) # memstore_01Hx...\n```\n\nOther SDKs: TypeScript `client.beta.memoryStores.create({...})`; Go `client.Beta.MemoryStores.New(ctx, ...)`. See `shared/managed-agents-api-reference.md` → SDK Method Reference for the full per-language table.\n\nStores support `retrieve` / `update` / `list` (with `include_archived`, `created_at_{gte,lte}` filters) / `delete` / **`archive`**. Archive makes the store read-only — existing session attachments continue, new sessions cannot reference it; no unarchive.\n\n### Seed with content (optional)\n\nPre-load reference material before any session runs. `memories.create` creates a memory at the given `path`; if a memory already exists there the call returns `409` (`memory_path_conflict_error`, with the `conflicting_memory_id`). The store ID is the first positional argument.\n\n```python\nclient.beta.memory_stores.memories.create(\n store.id,\n path=\"/formatting_standards.md\",\n content=\"All reports use GAAP formatting. Dates are ISO-8601...\",\n)\n```\n\n## Attach to a session\n\nMemory stores go in the session's `resources[]` array alongside `file` and `github_repository` resources (see `shared/managed-agents-environments.md` → Resources). Memory stores attach at **session create time only** — `sessions.resources.add()` does not accept `memory_store`.\n\n```python\nsession = client.beta.sessions.create(\n agent=agent.id,\n environment_id=environment.id,\n resources=[\n {\n \"type\": \"memory_store\",\n \"memory_store_id\": store.id,\n \"access\": \"read_write\", # or \"read_only\"; default is \"read_write\"\n \"instructions\": \"User preferences and project context. Check before starting any task.\",\n }\n ],\n)\n```\n\n| Field | Required | Notes |\n| --- | --- | --- |\n| `type` | ✅ | `\"memory_store\"` |\n| `memory_store_id` | ✅ | `memstore_...` |\n| `access` | — | `\"read_write\"` (default) or `\"read_only\"` — enforced at the filesystem level on the mount |\n| `instructions` | — | Session-specific guidance for this store, in addition to the store's `name`/`description`. ≤ 4,096 chars. |\n\n**Max 8 memory stores per session.** Attach multiple when different slices of memory have different owners or lifecycles — e.g. one read-only shared-reference store plus one read-write per-user store, or one store per end-user/team/project sharing a single agent config.\n\n### How the agent sees it (FUSE mount)\n\nEach attached store is mounted in the session container at `/mnt/memory/<store-name>/`. The agent interacts with it using the standard file tools (`bash`, `read`, `write`, `edit`, `glob`, `grep`) — there are no dedicated memory tools. `access: \"read_only\"` makes the mount read-only at the filesystem level; `\"read_write\"` allows the agent to create, edit, and delete files under it. A short description of each mount (name, path, `instructions`, access) is automatically injected into the system prompt so the agent knows the store exists without you having to mention it.\n\nWrites the agent makes under the mount are persisted back to the store and produce memory versions just like host-side `memories.update` calls.\n\n## Manage memories directly (host-side)\n\nUse these for review workflows, correcting bad memories, or seeding stores out-of-band.\n\n### List\n\nReturns `Memory | MemoryPrefix` entries — a `MemoryPrefix` (`type: \"memory_prefix\"`, just a `path`) is a directory-like node when listing hierarchically. Use `path_prefix` to scope (include a trailing slash: `\"/notes/\"` matches `/notes/a.md` but not `/notes_backup/old.md`) and `depth` to bound the tree walk. `order_by` / `order` sort the result. Pass `view=\"full\"` to include `content` in each item; the default `\"basic\"` returns metadata only.\n\n```python\nfor m in client.beta.memory_stores.memories.list(store.id, path_prefix=\"/\"):\n if m.type == \"memory\":\n print(f\"{m.path} ({m.content_size_bytes} bytes, sha={m.content_sha256[:8]})\")\n else: # \"memory_prefix\"\n print(f\"{m.path}/\")\n```\n\n### Read\n\n```python\nmem = client.beta.memory_stores.memories.retrieve(memory_id, memory_store_id=store.id)\nprint(mem.content)\n```\n\n`retrieve` defaults to `view=\"full\"` (content included); `view` matters mainly on list endpoints.\n\n### Create vs. update\n\n| Operation | Addressed by | Semantics |\n| --- | --- | --- |\n| `memories.create(store_id, path=..., content=...)` | **Path** | Create at `path`. `409` (`memory_path_conflict_error`, includes `conflicting_memory_id`) if the path is already occupied. |\n| `memories.update(mem_id, memory_store_id=..., path=..., content=...)` | **`mem_...` ID** | Mutate existing memory. Change `content`, `path` (rename), or both. Renaming onto an occupied path returns the same `409 memory_path_conflict_error`. |\n\n```python\nmem = client.beta.memory_stores.memories.create(\n store.id,\n path=\"/preferences/formatting.md\",\n content=\"Always use tabs, not spaces.\",\n)\n\nclient.beta.memory_stores.memories.update(\n mem.id,\n memory_store_id=store.id,\n path=\"/archive/2026_q1_formatting.md\", # rename\n)\n```\n\n### Optimistic concurrency (precondition on `update`)\n\n`memories.update` accepts a `precondition` so you can read → modify → write back without clobbering a concurrent writer. The only supported type is `content_sha256`. On mismatch the API returns `409` (`memory_precondition_failed_error`) — re-read and retry against fresh state.\n\n```python\nclient.beta.memory_stores.memories.update(\n mem.id,\n memory_store_id=store.id,\n content=\"CORRECTED: Always use 2-space indentation.\",\n precondition={\"type\": \"content_sha256\", \"content_sha256\": mem.content_sha256},\n)\n```\n\n### Delete\n\n```python\nclient.beta.memory_stores.memories.delete(mem.id, memory_store_id=store.id)\n```\n\nPass `expected_content_sha256` for a conditional delete.\n\n## Audit and rollback — memory versions\n\nEvery mutation creates an immutable `memver_...` snapshot. Versions accumulate for the lifetime of the parent memory; `memories.retrieve` always returns the current head, the version endpoints give you history.\n\n| Operation that triggers it | `operation` field on the version |\n| --- | --- |\n| `memories.create` at a new path | `\"created\"` |\n| `memories.update` changing `content`, `path`, or both (or an agent-side write to the mount) | `\"modified\"` |\n| `memories.delete` | `\"deleted\"` |\n\nEach version also records `created_by` — an actor object with `type` ∈ `session_actor` / `api_actor` / `user_actor` — and, after redaction, `redacted_at` + `redacted_by`.\n\n### List versions\n\nNewest-first, paginated. Filter by `memory_id`, `operation`, `session_id`, `api_key_id`, or `created_at_gte` / `created_at_lte`. Pass `view=\"full\"` to include `content`; default is metadata-only.\n\n```python\nfor v in client.beta.memory_stores.memory_versions.list(store.id, memory_id=mem.id):\n print(f\"{v.id}: {v.operation}\")\n```\n\n### Retrieve a version\n\n```python\nversion = client.beta.memory_stores.memory_versions.retrieve(\n version_id, memory_store_id=store.id\n)\nprint(version.content)\n```\n\n### Redact a version\n\nScrubs content from a historical version while preserving the audit trail (actor + timestamps). Clears `content`, `content_sha256`, `content_size_bytes`, and `path`; everything else stays. Use for leaked secrets, PII, or user-deletion requests.\n\n```python\nclient.beta.memory_stores.memory_versions.redact(version_id, memory_store_id=store.id)\n```\n\n## Endpoint reference\n\nSee `shared/managed-agents-api-reference.md` → Memory Stores / Memories / Memory Versions for the full HTTP method/path tables.

All agents **share the container and filesystem**; each runs in its own **thread** — a context-isolated event stream with its own conversation history, model, system prompt, tools, MCP servers, and skills (from that agent's own config). Threads are persistent: the coordinator can send a follow-up to a subagent it called earlier and that subagent retains its prior turns.\n\nThe SDK sets the `managed-agents-2026-04-01` beta header automatically on all `client.beta.{agents,sessions}.*` calls; no additional header is required for multiagent.\n\n---\n\n## Declare the roster on the coordinator\n\n`multiagent` is a **top-level field** on `agents.create()` / `agents.update()` — **not** a `tools[]` entry. `agents` lists 1–20 roster entries. Nothing changes on `sessions.create()` — the roster is resolved from the coordinator's config.\n\n```python\norchestrator = client.beta.agents.create(\n name=\"Engineering Lead\",\n model=\"claude-opus-4-8\",\n system=\"You coordinate engineering work. Delegate code review to the reviewer and test writing to the test agent.\",\n tools=[{\"type\": \"agent_toolset_20260401\"}],\n multiagent={\n \"type\": \"coordinator\",\n \"agents\": [\n reviewer.id, # bare string — latest version\n {\"type\": \"agent\", \"id\": test_writer.id, \"version\": 4}, # pinned version\n {\"type\": \"self\"}, # the coordinator itself\n ],\n },\n)\n\nsession = client.beta.sessions.create(agent=orchestrator.id, environment_id=env.id)\n```\n\n| Roster entry | Shape | Notes |\n|---|---|---|\n| String shorthand | `\"agent_abc123\"` | References the latest version of a stored agent. |\n| Agent reference | `{type: \"agent\", id, version?}` | Omit `version` to pin the latest at coordinator save time. |\n| Self | `{type: \"self\"}` | The coordinator can spawn copies of itself. |\n\nIf the session was created with `agent_with_overrides` (see `shared/managed-agents-core.md` → Override agent configuration for a session), those overrides apply to the **coordinator and its `self` copies**. Roster agents referenced by ID always use their own as-created configuration — overrides do not propagate to them.\n\nUp to **20 unique agents** in the roster; the coordinator may spawn **multiple copies** of each. **One level of delegation only** — depth > 1 is ignored.\n\n---\n\n## Threads\n\nThe session-level event stream is the **primary thread** — it shows the coordinator's trace plus a condensed view of subagent activity (thread status transitions and cross-thread messages, not every subagent tool call). Drill into a specific subagent via the per-thread endpoints:\n\n| Operation | HTTP | SDK (`client.beta.sessions.threads.*`) |\n|---|---|---|\n| List threads | `GET /v1/sessions/{sid}/threads` | `.list(session_id)` |\n| Retrieve one | `GET /v1/sessions/{sid}/threads/{tid}` | `.retrieve(thread_id, session_id=...)` |\n| Archive | `POST /v1/sessions/{sid}/threads/{tid}/archive` | `.archive(thread_id, session_id=...)` |\n| List thread events | `GET /v1/sessions/{sid}/threads/{tid}/events` | `.events.list(thread_id, session_id=...)` |\n| Stream thread events | `GET /v1/sessions/{sid}/threads/{tid}/stream` | `.events.stream(thread_id, session_id=...)` |\n\nEach `SessionThread` carries `id`, `status` (`running` | `idle` | `rescheduling` | `terminated`), `agent` (a resolved snapshot of the agent config — `id`, `name`, `model`, `system`, `tools`, `skills`, `mcp_servers`, `version`), `parent_thread_id` (null for the primary thread, which is included in the list), `archived_at`, and optional `stats`/`usage`. **Session status aggregates thread statuses** — if any thread is `running`, `session.status` is `running`. Max **25 concurrent threads**. When draining a per-thread stream, break on `session.thread_status_idle` (and check its `stop_reason` as you would for the session-level idle).\n\n---\n\n## Multiagent events (on the session stream)\n\n| Event | Payload highlights | Meaning |\n|---|---|---|\n| `session.thread_created` | `session_thread_id`, `agent_name` | A new thread was created. |\n| `session.thread_status_running` | `session_thread_id`, `agent_name` | Thread started activity. |\n| `session.thread_status_idle` | `session_thread_id`, `agent_name`, **`stop_reason`** | Thread is awaiting input. Inspect `stop_reason` (same shape as `session.status_idle.stop_reason`). |\n| `session.thread_status_rescheduled` | `session_thread_id`, `agent_name` | Thread is rescheduling after a retryable error. |\n| `session.thread_status_terminated` | `session_thread_id`, `agent_name` | Thread was archived or hit a terminal error. |\n| `agent.thread_message_sent` | `to_session_thread_id`, `to_agent_name`, `content` | Coordinator sent a follow-up to another thread. |\n| `agent.thread_message_received` | `from_session_thread_id`, `from_agent_name`, `content` | An agent delivered its result to the coordinator. |\n\n---\n\n## Tool permissions and custom tools from subagent threads\n\nWhen a subagent needs your client (an `always_ask` confirmation, or a custom tool result), the request is **cross-posted to the primary thread** with `session_thread_id` identifying the originating thread — so you only need to watch the session stream. Reply with `user.tool_confirmation` (carrying `tool_use_id`) or `user.custom_tool_result` (carrying `custom_tool_use_id`), and **echo the `session_thread_id` from the originating event** (the SDK param type and docstring expect it). The server also routes by the tool-use ID, so the echo is belt-and-suspenders rather than load-bearing — but include it.\n\n```python\nfor event_id in stop.event_ids:\n pending = events_by_id[event_id]\n confirmation = {\n \"type\": \"user.tool_confirmation\",\n \"tool_use_id\": event_id,\n \"result\": \"allow\",\n }\n if pending.session_thread_id is not None:\n confirmation[\"session_thread_id\"] = pending.session_thread_id\n client.beta.sessions.events.send(session.id, events=[confirmation])\n```\n\nThe same pattern applies to `user.custom_tool_result`.\n\n---\n\n## Pitfalls\n\n- **Don't put the roster on `sessions.create()` or in `tools[]`.** `multiagent` is a top-level agent field; update the coordinator, then start a session that references it.\n- **Don't assume shared context.** Threads share the filesystem but not conversation history or tools. If the coordinator needs a subagent to act on something, it must say so in the delegated message (or write it to disk).\n- **Depth > 1 is ignored.** A subagent's own `multiagent` roster (if any) doesn't cascade — only the session's coordinator delegates.\n\nFor per-language bindings beyond Python, WebFetch `https://platform.claude.com/docs/en/managed-agents/multi-agent.md` (see `shared/live-sources.md`).\n</doc>\n\n<doc path=\"shared/managed-agents-onboarding.md\">\n# Managed Agents — Onboarding Flow\n\n> **Invoked via `/claude-api managed-agents-onboard`?** You're in the right place. Run the interview below — don't summarize it back to the user, ask the questions.\n\nClaude Managed Agents is a hosted agent: Anthropic runs the agent loop and provisions a sandboxed container per session where the agent's tools execute (or your own worker, with a `self_hosted` environment — see `shared/managed-agents-self-hosted-sandboxes.md`). You supply an **agent config** (tools, skills, model, system prompt — reusable, versioned) and an **environment config** (the sandbox — reusable across agents). Each run is a **session**.\n\nThe flow is four beats — **describe → agent → environment → session** — the same arc as the Console quickstart, and the same philosophy: **value before credentials**. The user goes from idea to a runnable session before any auth ask; each credential is *flagged* at the moment the design makes it relevant (§2) and *collected* once, at session setup (§4), where it binds (`sessions.create()`) and gets exercised (smoke-test). Read `shared/managed-agents-core.md` alongside this — it has full detail for each knob; this doc is the interview script.\n\n---\n\n## 1. Describe the task\n\n**Open with a one-breath signpost and a single open prompt — don't guess, don't questionnaire.** In your own words:\n\n> Managed Agents is hosted — Anthropic runs the agent loop, the sandbox, and the infrastructure; you just define the agent. We'll do this in three moves: the agent, the environment it runs in, then a live test session. So: describe the agent you want — what should it do, and what kicks it off (a person, an event, a schedule)?\n\nLet them answer in full before configuring anything.\n\n## 2. Configure the agent — propose, don't interrogate\n\nTheir description does the interview's work. Draft the agent config from it and **present it as a proposal with your suggestions inline** — the user reacts to a concrete config instead of answering a question list. At most one batched follow-up for true gaps. Suggest where the description gives you an opening:\n\n- **Tools** — enable the full prebuilt toolset by default (`agent_toolset_20260401`: `bash`, `read`, `write`, `edit`, `glob`, `grep`, `web_fetch`, `web_search`). **Suggest MCP servers** for any third-party service the job names (GitHub, Linear, Slack, …) — and flag the credential each one implies as you suggest it (\"Linear MCP → you'll need a Linear API token at kickoff\"), so §4's auth step is a formality, not a surprise. Collection itself waits for §4. Custom tools only if the user's own app must answer calls (name, description, input schema — their handler code is theirs; don't generate it).\n- **Skills** — **suggest** prebuilt `xlsx`/`docx`/`pptx`/`pdf` when the job produces those artifacts; custom by `skill_id` (max 20 total per agent, prebuilt + custom combined).\n- **Outcome** — if the description implies checkable \"done\" criteria (or you can elicit them in the follow-up: not \"a good report\" but \"a CSV with a numeric `price` column per SKU\"), **suggest an Outcome kickoff** — the harness grades and iterates against a rubric (`shared/managed-agents-outcomes.md`).\n- **On-hand resources** — repos on disk (`github_repository`: URL, optional `mount_path`/`checkout`; token comes in §4), files to seed (Files API upload → `{type: \"file\", file_id, mount_path}`; read-only), if the job references them.\n- **Model** — default `claude-opus-4-8`; `claude-fable-5` for the hardest long-horizon work (`shared/model-migration.md` → Migrating to Claude Fable 5).\n\n> ‼️ **PR creation needs the GitHub MCP server too** — a `github_repository` mount is filesystem-only. Edit in the mount → push branch via `bash` → open the PR via the MCP `create_pull_request` tool.\n\nFull detail per knob: `shared/managed-agents-tools.md` (toolset, MCP, custom tools, skills), `shared/managed-agents-environments.md` (repos, files).\n\n## 3. Environment\n\nUsually zero or one question:\n\n- **Reuse or create?** Environments are shared across agents — check for an existing one first.\n- **Networking** — default unrestricted egress. Switch to `limited` only if the user wants egress control — then set `allow_mcp_servers: true` or list every MCP server domain in `allowed_hosts`, or those tools fail silently.\n- **Suggest `self_hosted`** when the signals are there: tools must run on their own infra, secrets can't leave it, or they need binaries/data the cloud container won't have (`shared/managed-agents-self-hosted-sandboxes.md`; not available on Claude Platform on AWS). Otherwise `cloud` — don't raise it unprompted for simple jobs.\n\n## 4. Session — auth, then test run\n\n**Auth happens here — collect the credentials flagged in §2, now that the config is settled:** a vault (existing or `vaults.create()`) + `vaults.credentials.create()` for each MCP server declared in §2, `environment_variable` credentials for API keys the job uses (substituted at egress; the sandbox sees a placeholder), and the `authorization_token` for each repo mount. Credentials are write-only; MCP credentials match servers by URL and auto-refresh. See `shared/managed-agents-tools.md` → Vaults.\n\n**Silent viability gate — run this yourself before emitting anything; surface only the gaps.** Walk the job clause by clause: every verb maps to an enabled tool or MCP server (\"open a PR\" → GitHub MCP, not just the mount); every MCP server and repo mount has its credential from the auth step; every external host is reachable under the networking choice; every file/repo/dataset the job references is mounted; \"done\" is checkable. If something's missing, say so and resolve it — don't emit a config you already know is under-resourced.\n\n**Kickoff — pick one, never both:**\n- `user.message` — conversational.\n- `user.define_outcome` + rubric — when §2 settled on an Outcome; the harness iterates and grades until the rubric passes.\n- **Scheduled shape?** Skip per-session kickoff entirely — create a **deployment** (`deployments.create()` with `schedule` + `initial_events`); each firing creates the session autonomously. See `shared/managed-agents-scheduled-deployments.md`.\n\nMechanics to bake into the runtime code: session creation blocks until resources mount (bad mounts surface there, before tokens); open the event stream *before* sending the kickoff; break on `session.status_terminated`, or `session.status_idle` with a terminal `stop_reason` — anything except `requires_action` (`shared/managed-agents-client-patterns.md` Pattern 5); usage lands on `span.model_request_end`; artifacts land in `/mnt/session/outputs/` (`files.list({scope_id: session.id, ...})`).\n\n## 5. Integrate — emit the code\n\nGo straight from the last answer to the code — no preamble, no lecture about setup-vs-runtime; the two-block structure shows it. Generate **two clearly-separated blocks**:\n\n**Block 1 — Setup (run once, store the IDs).** Prefer **YAML files + `ant` CLI** — agents and environments are version-controlled definitions users should check in and apply from CI:\n\n1. `<name>.agent.yaml` (flat: `name`, `model`, `system`, `tools`, `mcp_servers`, `skills`) and `<name>.environment.yaml`\n2. ```sh\n AGENT_ID=$(ant beta:agents create < <name>.agent.yaml --transform id -r)\n ENV_ID=$(ant beta:environments create < <name>.environment.yaml --transform id -r)\n # CI sync: ant beta:agents update --agent-id \"$AGENT_ID\" --version N < <name>.agent.yaml\n ```\n\nSDK fallback if the user asks — and **required on Claude Platform on AWS**, where auth is SigV4 and the `ant` CLI has no SigV4 mode (use the platform client from `shared/claude-platform-on-aws.md`): label it `# ONE-TIME SETUP — run once, save the IDs` and call `environments.create()` → `agents.create()`.\n\n> ⚠️ **Deployments are newer than the rest of the MA surface.** Before emitting `ant beta:deployments …` or `client.beta.deployments` / `client.beta.deployment_runs` calls, verify the user's installed CLI/SDK exposes them (`ant beta:deployments --help`; `hasattr(client.beta, \"deployments\")`). If not, emit raw HTTP against `POST /v1/deployments` with the `managed-agents-2026-04-01` beta header (plus `oauth-2025-04-20` when authenticating with a Bearer token from `ant auth print-credentials`), and leave an upgrade note marking what simplifies to SDK calls.\n\n**Scheduled shape? The deployment is setup, not runtime.** Create it in Block 1, after the agent/environment IDs exist (`deployments.create()` with `schedule` + `initial_events`). Block 2 is then **not** a session loop — there is no per-run kickoff to send. Emit instead: a manual-run trigger (`POST /v1/deployments/{id}/run`) so the user can test now rather than wait for the first firing — the manual run doubles as the smoke test — plus a fetch helper (latest `deployment_runs` entry → `session_id` → Console URL + `files.list(scope_id=session_id)` for the artifacts).\n\n**Block 2 — Runtime (every invocation; conversational and Outcome shapes).** SDK code in the detected language (Python/TS/cURL — SKILL.md → Language Detection); don't emit shell loops here:\n\n1. Load `agent_id` + `env_id` from config/env\n2. `sessions.create(agent=AGENT_ID, environment_id=ENV_ID, resources=[...], vault_ids=[...])`, then print the Console URL so the user can watch live: `https://platform.claude.com/workspaces/default/sessions/{session.id}` (swap `default` for their workspace slug)\n3. **Smoke-test when the job depends on MCP servers, credentials, or locked-down hosts** — those failures don't surface at `sessions.create()`, only on first use. One cheap probe turn (\"Confirm you can reach <service> and list 1–2 items; don't start the task\"), verify, then send the real kickoff. Skip when there are no external dependencies.\n4. Open stream → send the §4 kickoff → loop with the terminal gate from §4.\n\n> ⚠️ **Never emit `agents.create()` and `sessions.create()` in the same unguarded block** — that teaches creating a new agent per run, the #1 anti-pattern. Single-script requests: wrap creation in `if not os.getenv(\"AGENT_ID\"):`.\n\nPull exact syntax from `{lang}/managed-agents/README.md` for your detected language (cURL and C#: use `curl/managed-agents.md` as the wire-level reference). Don't invent field names.\n</doc>\n\n<doc path=\"shared/managed-agents-outcomes.md\">\n# Managed Agents — Outcomes\n\nAn **outcome** elevates a session from *conversation* to *work*: you state what \"done\" looks like, and the harness runs an iterate → grade → revise loop until the artifact meets the rubric, hits `max_iterations`, or is interrupted. A separate **grader** (independent context window) scores each iteration against your rubric and feeds per-criterion gaps back to the agent.\n\nThe SDK sets the `managed-agents-2026-04-01` beta header automatically on all `client.beta.sessions.*` calls; no additional header is required for outcomes.\n\n---\n\n## The `user.define_outcome` event\n\nOutcomes are not a field on `sessions.create()`. You create a normal session, then send a `user.define_outcome` event. The agent starts working on receipt — **do not also send a `user.message`** to kick it off.\n\n```python\nsession = client.beta.sessions.create(\n agent=AGENT_ID,\n environment_id=ENVIRONMENT_ID,\n title=\"Financial analysis on Costco\",\n)\n\nclient.beta.sessions.events.send(\n session_id=session.id,\n events=[\n {\n \"type\": \"user.define_outcome\",\n \"description\": \"Build a DCF model for Costco in .xlsx\",\n \"rubric\": {\"type\": \"text\", \"content\": RUBRIC_MD},\n # or: \"rubric\": {\"type\": \"file\", \"file_id\": rubric.id}\n \"max_iterations\": 5, # optional; default 3, max 20\n }\n ],\n)\n```\n\n| Field | Type | Notes |\n|---|---|---|\n| `type` | `\"user.define_outcome\"` | |\n| `description` | string | The task. This is what the agent works toward — no separate `user.message` needed. |\n| `rubric` | `{type: \"text\", content}` \\| `{type: \"file\", file_id}` | **Required.** Markdown with explicit, independently gradeable criteria. Upload once via `client.beta.files.upload(...)` (beta `files-api-2025-04-14`) to reuse across sessions. |\n| `max_iterations` | int | Optional. Default **3**, max **20**. |\n\nThe event is echoed back on the stream with a server-assigned `outcome_id` and `processed_at`.\n\n> **Writing rubrics.** Use explicit, gradeable criteria (\"CSV has a numeric `price` column\"), not vibes (\"data looks good\") — the grader scores each criterion independently, so vague criteria produce noisy loops. If you don't have a rubric, have Claude analyze a known-good artifact and turn that analysis into one.\n\n---\n\n## Outcome-specific events\n\nThese appear on the standard event stream (`sessions.events.stream` / `.list`) alongside the usual `agent.*` / `session.*` events.\n\n| Event | Payload highlights | Meaning |\n|---|---|---|\n| `span.outcome_evaluation_start` | `outcome_id`, `iteration` (0-indexed) | Grader began scoring iteration *N*. |\n| `span.outcome_evaluation_ongoing` | `outcome_id` | Heartbeat while the grader runs. Grader reasoning is opaque — you see *that* it's working, not *what* it's thinking. |\n| `span.outcome_evaluation_end` | `outcome_evaluation_start_id`, `outcome_id`, `iteration`, `result`, `explanation`, `usage` | Grader finished one iteration. `result` drives what happens next (table below). |\n\n### `span.outcome_evaluation_end.result`\n\n| `result` | Next |\n|---|---|\n| `satisfied` | Session → `idle`. Terminal for this outcome. |\n| `needs_revision` | Agent starts another iteration. |\n| `max_iterations_reached` | No further grader cycles. Agent may run one final revision, then session → `idle`. |\n| `failed` | Session → `idle`. Rubric fundamentally doesn't match the task (e.g. description and rubric contradict). |\n| `interrupted` | Only emitted if `_start` had already fired before a `user.interrupt` arrived. |\n\n```json\n{\n \"type\": \"span.outcome_evaluation_end\",\n \"id\": \"sevt_01jkl...\",\n \"outcome_evaluation_start_id\": \"sevt_01def...\",\n \"outcome_id\": \"outc_01a...\",\n \"result\": \"satisfied\",\n \"explanation\": \"All 12 criteria met: revenue projections use 5 years of historical data, ...\",\n \"iteration\": 0,\n \"usage\": { \"input_tokens\": 2400, \"output_tokens\": 350, \"cache_creation_input_tokens\": 0, \"cache_read_input_tokens\": 1800 },\n \"processed_at\": \"2026-03-25T14:03:00Z\"\n}\n```\n\n---\n\n## Checking status & retrieving deliverables\n\n**Status** — either watch the stream for `span.outcome_evaluation_end`, or poll the session and read `outcome_evaluations`:\n\n```python\nsession = client.beta.sessions.retrieve(session.id)\nfor ev in session.outcome_evaluations:\n print(f\"{ev.outcome_id}: {ev.result}\") # outc_01a...: satisfied\n```\n\n**Deliverables** — the agent writes to `/mnt/session/outputs/`. Once idle, fetch via the Files API with `scope_id=session.id`. This is the same session-outputs mechanism documented in `shared/managed-agents-environments.md` → Session outputs (including the dual-beta-header requirement on `files.list`).\n\n---\n\n## Interaction rules & pitfalls\n\n- **One outcome at a time.** Chain by sending the next `user.define_outcome` only after the previous one's terminal `span.outcome_evaluation_end` (`satisfied` / `max_iterations_reached` / `failed` / `interrupted`). The session retains history across chained outcomes.\n- **Steering is allowed but optional.** You *may* send `user.message` events mid-outcome to nudge direction, but the agent already knows to keep working until terminal — don't send \"keep going\" prompts.\n- **`user.interrupt` pauses the current outcome** — it marks `result: \"interrupted\"` and leaves the session `idle`, ready for a new outcome or conversational turn.\n- **After terminal, the session is reusable** — continue conversationally or define a new outcome.\n- **Outcome ≠ session-create field.** Don't put `outcome`, `rubric`, or `description` on `sessions.create()` — outcomes are always sent as a `user.define_outcome` event.\n- **Idle-break gate is unchanged.** In your drain loop, keep using `event.type === 'session.status_idle' && event.stop_reason?.type !== 'requires_action'` — do **not** gate on `span.outcome_evaluation_end` alone (on `needs_revision` the session keeps running). See `shared/managed-agents-client-patterns.md` Pattern 5.\n\nFor the raw HTTP shapes and per-language SDK bindings beyond Python, WebFetch `https://platform.claude.com/docs/en/managed-agents/define-outcomes.md` (see `shared/live-sources.md`).\n</doc>\n\n<doc path=\"shared/managed-agents-overview.md\">\n# Managed Agents — Overview\n\nManaged Agents provisions a container per session as the agent's workspace. The agent loop runs on Anthropic's orchestration layer; the container is where the agent's *tools* execute — bash commands, file operations, code. You create a persisted **Agent** config (model, system prompt, tools, MCP servers, skills), then start **Sessions** that reference it. The session streams events back to you; you send user messages and tool results in.\n\n## ⚠️ THE MANDATORY FLOW: Agent (once) → Session (every run)\n\n**Why agents are separate objects: versioning.** An agent is a persisted, versioned config — every update creates a new immutable version, and sessions pin to a version at creation time. This lets you iterate on the agent (tweak the prompt, add a tool) without breaking sessions already running, roll back if a change regresses, and A/B test versions side-by-side. None of that works if you `agents.create()` fresh on every run.\n\nEvery session references a pre-created `/v1/agents` object. Create the agent once, store the ID, and reuse it across runs.\n\n| Step | Call | Frequency |\n|---|---|---|\n| 1 | `POST /v1/agents` — `model`, `system`, `tools`, `mcp_servers`, `skills` live here | **ONCE.** Store `agent.id` **and** `agent.version`. |\n| 2 | `POST /v1/sessions` — `agent: \"agent_abc123\"` or `{type: \"agent\", id, version}` | **Every run.** String shorthand uses latest version. |\n\nIf you're about to write `sessions.create()` with `model`, `system`, or `tools` on the session body — **stop**. Those fields live on `agents.create()`. The session takes a *pointer* only.\n\n**When generating code, separate setup from runtime.** `agents.create()` belongs in a setup script (or a guarded `if agent_id is None:` block), not at the top of the hot path. If the user's code calls `agents.create()` on every invocation, they're accumulating orphaned agents and paying the create latency for nothing. The correct shape is: create once → persist the ID (config file, env var, secrets manager) → every run loads the ID and calls `sessions.create()`.\n\n**To change the agent's behavior, use `POST /v1/agents/{id}` — don't create a new one.** Each update bumps the version; running sessions keep their pinned version, new sessions get the latest (or pin explicitly via `{type: \"agent\", id, version}`). See `shared/managed-agents-core.md` → Agents → Versioning. To change `tools`/`mcp_servers`/`vault_ids` on **one running session** without touching the agent object, use `sessions.update()` — see `shared/managed-agents-core.md` → Updating the agent configuration mid-session.\n\n## Beta Headers\n\nManaged Agents is in beta. The SDK sets required beta headers automatically:\n\n| Beta Header | What it enables |\n| ------------------------------ | ---------------------------------------------------- |\n| `managed-agents-2026-04-01` | Agents, Environments, Sessions, Events, Session Resources, Session Threads, Outcomes, Multiagent, Vaults, Credentials, Memory Stores, Deployments |\n| `skills-2025-10-02` | Skills API (for managing custom skill definitions) |\n| `files-api-2025-04-14` | Files API for file uploads |\n\n**Which beta header goes where:** The SDK sets `managed-agents-2026-04-01` automatically on `client.beta.{agents,environments,sessions,vaults,memory_stores,deployments,deployment_runs}.*` calls, and `files-api-2025-04-14` / `skills-2025-10-02` automatically on `client.beta.files.*` / `client.beta.skills.*` calls. You do NOT need to add the Skills or Files beta header when calling Managed Agents endpoints. **Exception — session-scoped file listing:** `client.beta.files.list({scope_id: session.id})` is a Files endpoint that takes a Managed Agents parameter, so it needs **both** headers. Pass `betas: [\"managed-agents-2026-04-01\"]` explicitly on that call (the SDK adds the Files header; you add the Managed Agents one). See `shared/managed-agents-environments.md` → Session outputs.\n\n\n## Reading Guide\n\n| User wants to... | Read these files |\n| -------------------------------------- | ------------------------------------------------------- |\n| **Get started from scratch / \"help me set up an agent\"** | `shared/managed-agents-onboarding.md` — guided interview (WHERE→WHO→WHAT→WATCH), then emit code |\n| Understand how the API works | `shared/managed-agents-core.md` |\n| See the full endpoint reference | `shared/managed-agents-api-reference.md` |\n| **Create an agent** (required first step) | `shared/managed-agents-core.md` (Agents section) + language file |\n| Update/version an agent | `shared/managed-agents-core.md` (Agents → Versioning) — update, don't re-create |\n| Create a session | `shared/managed-agents-core.md` + `{lang}/managed-agents/README.md` (cURL/C#: `curl/managed-agents.md`) |\n| Configure tools and permissions | `shared/managed-agents-tools.md` |\n| Set up MCP servers | `shared/managed-agents-tools.md` (MCP Servers section) |\n| Stream events / handle tool_use | `shared/managed-agents-events.md` + language file |\n| Get notified of session state changes via webhook (no polling) | `shared/managed-agents-webhooks.md` — Console-registered endpoint, HMAC verify, thin payload + fetch |\n| Define an outcome / rubric-graded iterate loop | `shared/managed-agents-outcomes.md` — `user.define_outcome` event, grader, `span.outcome_evaluation_*` events |\n| Coordinate multiple agents / subagents / threads | `shared/managed-agents-multiagent.md` — `multiagent: {type: \"coordinator\", agents: [...]}` on the agent, session threads, cross-posted tool confirmations |\n| Set up environments | `shared/managed-agents-environments.md` + language file |\n| Run tool execution in your own infra / VPC (self-hosted sandbox) | `shared/managed-agents-self-hosted-sandboxes.md` — `config:{type:\"self_hosted\"}`, `ANTHROPIC_ENVIRONMENT_KEY`, `EnvironmentWorker.run()` / `ant beta:worker poll` |\n| Upload files / attach repos | `shared/managed-agents-environments.md` (Resources) |\n| Give agents persistent memory across sessions | `shared/managed-agents-memory.md` — memory stores, `memory_store` session resource, preconditions, versions/redact |\n| Define agents/environments as version-controlled YAML; drive the API from the shell | `shared/anthropic-cli.md` — `ant beta:agents create < agent.yaml`, `--transform`, `@file` inlining |\n| Store credentials (MCP auth, API keys for CLIs/SDKs) | `shared/managed-agents-tools.md` (Vaults section) — `mcp_oauth` / `static_bearer` / `environment_variable` |\n| Call a non-MCP API / CLI that needs a secret | `shared/managed-agents-tools.md` (Vaults section) — `environment_variable` credential, substituted at egress. If that doesn't fit (e.g. self-hosted sandboxes), `shared/managed-agents-client-patterns.md` Pattern 9 keeps the secret host-side via a custom tool |\n| Run an agent on a recurring cron schedule | `shared/managed-agents-scheduled-deployments.md` — deployments, deployment runs, pause/auto-pause |\n\n## Common Pitfalls\n\n- **Agent FIRST, then session — NO EXCEPTIONS** — the session's `agent` field accepts **only** a string ID or `{type: \"agent\", id, version}`. `model`, `system`, `tools`, `mcp_servers`, `skills` are **top-level fields on `POST /v1/agents`**, never on `sessions.create()`. If the user hasn't created an agent, that is step zero of every example.\n- **Agent ONCE, not every run** — `agents.create()` is a setup step. Store the returned `agent_id` and reuse it; don't call `agents.create()` at the top of your hot path. If the agent's config needs to change, `POST /v1/agents/{id}` — each update creates a new version, and sessions can pin to a specific version for reproducibility.\n- **MCP auth goes through vaults** — the agent's `mcp_servers` array declares `{type, name, url}` only (no auth). Credentials live in vaults (`client.beta.vaults.credentials.create`) and attach to sessions via `vault_ids`. Anthropic auto-refreshes OAuth tokens using the stored refresh token. Vaults also hold `environment_variable` credentials for non-MCP services (CLIs, SDKs, direct API calls) — substituted at egress, never visible in the sandbox.\n- **Reconcile resources before the first run** — a session with a clear ask but a missing tool, credential, data mount, or context will discover the gap mid-run, then flail and give up. Before creating the session, check that every action in the task maps to a configured tool/MCP server, every MCP server has a vault credential, and every referenced file/host is mounted/reachable. When helping a user set one up, run the reconciliation in `shared/managed-agents-onboarding.md` → §3 Pre-flight viability check.\n- **Stream to get events** — `GET /v1/sessions/{id}/events/stream` is the primary way to receive agent output in real-time.\n- **SSE stream has no replay — reconnect with consolidation** — if the stream drops while a `agent.tool_use`, `agent.mcp_tool_use`, or `agent.custom_tool_use` is pending resolution (`user.tool_confirmation` for the first two, `user.custom_tool_result` for the last one), the session deadlocks (client disconnects → session idles → reconnect happens → no client resolution happens). On every (re)connect: open stream with `GET /v1/sessions/{id}/events/stream` , fetch `GET /v1/sessions/{id}/events`, dedupe by event ID, then proceed. See `shared/managed-agents-events.md` → Reconnecting after a dropped stream.\n- **Don't trust HTTP-library timeouts as wall-clock caps** — `requests` `timeout=(c, r)` and `httpx.Timeout(n)` are *per-chunk* read timeouts; they reset every byte, so a trickling connection can block indefinitely. For a hard deadline on raw-HTTP polling, track `time.monotonic()` at the loop level and bail explicitly. Prefer the SDK's `sessions.events.stream()` / `session.events.list()` over hand-rolled HTTP. See `shared/managed-agents-events.md` → Receiving Events.\n- **Messages queue** — you can send events while the session is `running` or `idle`; they're processed in order. No need to wait for a response before sending the next message.\n- **Environment `config.type` is `\"cloud\"` or `\"self_hosted\"`** — `cloud` runs the container on Anthropic's infrastructure; `self_hosted` moves tool execution to your own (see `shared/managed-agents-self-hosted-sandboxes.md`).\n- **Archive is permanent on every resource** — archiving an agent, environment, session, vault, credential, or memory store makes it read-only with no unarchive. For agents, environments, and memory stores specifically, archived resources cannot be referenced by new sessions (existing sessions continue). Do not call `.archive()` on a production agent, environment, or memory store as cleanup — **always confirm with the user before archiving**.\n</doc>\n\n<doc path=\"shared/managed-agents-scheduled-deployments.md\">\n# Managed Agents — Scheduled Deployments\n\nA **scheduled deployment** runs an agent on a recurring cron schedule — each firing creates a session autonomously. Use it for predictable-cadence work: nightly triage, weekly compliance scans, hourly monitors.\n\nRequires the `managed-agents-2026-04-01` beta header (the SDK sets it automatically for `client.beta.deployments.*` / `client.beta.deployment_runs.*` calls).\n\n## Create a deployment\n\nA deployment bundles everything a session needs (agent, environment, optional files / GitHub / memory stores / vaults) plus a `schedule` and the `initial_events` that kick off each run:\n\n- `agent` and `environment_id` are required — same shapes as `sessions.create` (see `shared/managed-agents-core.md`).\n- `initial_events` must contain the starting `user.message`.\n- `schedule` takes a cron `expression` and an IANA `timezone`. Minute-level granularity is the maximum.\n\n```bash\ncurl -fsSL https://api.anthropic.com/v1/deployments \\\n -H \"x-api-key: $ANTHROPIC_API_KEY\" \\\n -H \"anthropic-version: 2023-06-01\" \\\n -H \"anthropic-beta: managed-agents-2026-04-01\" \\\n -H \"content-type: application/json\" \\\n -d @- <<EOF\n{\n \"name\": \"Weekly compliance scan\",\n \"agent\": \"$AGENT_ID\",\n \"environment_id\": \"$ENVIRONMENT_ID\",\n \"initial_events\": [\n {\"type\": \"user.message\", \"content\": [{\"type\": \"text\", \"text\": \"Run the weekly compliance scan.\"}]}\n ],\n \"schedule\": {\n \"type\": \"cron\",\n \"expression\": \"0 20 * * 5\",\n \"timezone\": \"America/New_York\"\n }\n}\nEOF\n```\n\n```python\ndeployment = client.beta.deployments.create(\n name=\"Weekly compliance scan\",\n agent=agent.id,\n environment_id=environment.id,\n initial_events=[\n {\n \"type\": \"user.message\",\n \"content\": [{\"type\": \"text\", \"text\": \"Run the weekly compliance scan.\"}],\n },\n ],\n schedule={\n \"type\": \"cron\",\n \"expression\": \"0 20 * * 5\",\n \"timezone\": \"America/New_York\",\n },\n)\n```\n\nThe response is a deployment object (`depl_` ID prefix). Check `schedule.upcoming_runs_at` — the next fire times — to confirm the schedule parses the way you intended:\n\n```json\n{\n \"id\": \"depl_01xyz\",\n \"status\": \"active\",\n \"paused_reason\": null,\n \"schedule\": {\n \"type\": \"cron\",\n \"expression\": \"0 20 * * 5\",\n \"timezone\": \"America/New_York\",\n \"last_run_at\": null,\n \"upcoming_runs_at\": [\"2026-05-09T00:00:00Z\", \"2026-05-16T00:00:00Z\", \"2026-05-23T00:00:00Z\"]\n }\n}\n```\n\nDeployments may apply up to **10 seconds of jitter** to distribute load. Maximum **1000 scheduled deployments per organization** (contact Anthropic support for more).\n\n### Cron and timezone semantics\n\n- **Expression:** standard POSIX cron (`minute hour day-of-month month day-of-week`).\n- **Timezone:** IANA identifier (e.g. `\"America/Los_Angeles\"`).\n- **DST:** literal wall-clock matching — `\"0 20 * * *\"` in `America/New_York` fires at 8:00 PM local regardless of EST/EDT.\n\n> ⚠️ **DST edge:** wall-clock times that don't exist on a spring-forward day (e.g. 2AM) are **skipped**; times that occur twice on a fall-back day **fire twice**. Schedule outside the 1–3AM local window, or use UTC, when missed or duplicate executions are unacceptable.\n\n## Deployment runs\n\nEvery trigger attempt — successful or not — writes a **deployment run** record (`drun_` prefix), so you can audit failures independent of the session lifecycle. A successful run carries the created `session_id`; follow that session via the event stream (`shared/managed-agents-events.md`) or webhooks (`shared/managed-agents-webhooks.md`) as usual. A failed run carries an `error` whose `type` explains why session creation was rejected.\n\n```python\n# All runs for a deployment\nfor run in client.beta.deployment_runs.list(deployment_id=deployment.id):\n print(run.created_at, run.session_id or run.error.type)\n\n# Failures only\nfor run in client.beta.deployment_runs.list(deployment_id=deployment.id, has_error=True):\n print(run.created_at, run.error.type, run.error.message)\n```\n\n```typescript\nfor await (const run of client.beta.deploymentRuns.list({\n deployment_id: deployment.id,\n has_error: true,\n})) {\n console.log(run.created_at, run.error?.type, run.error?.message);\n}\n```\n\nRaw HTTP: `GET /v1/deployment_runs?deployment_id=...&has_error=true`. To retrieve a single run by ID, `GET /v1/deployment_runs/{deployment_run_id}` (SDK: `client.beta.deployment_runs.retrieve(run_id)`) — a `deployment_run.*` webhook event carries the run ID as its `data.id`.\n\nA failed run looks like:\n\n```json\n{\n \"type\": \"deployment_run\",\n \"id\": \"drun_01abc124\",\n \"deployment_id\": \"depl_01xyz\",\n \"trigger_context\": { \"type\": \"schedule\", \"scheduled_at\": \"2026-05-09T00:00:00Z\" },\n \"session_id\": null,\n \"error\": { \"type\": \"environment_archived\", \"message\": \"environment `env_01abc` is archived\" },\n \"agent\": { \"type\": \"agent\", \"id\": \"agent_01ghi789\", \"version\": 3 },\n \"created_at\": \"2026-05-09T00:00:01Z\"\n}\n```\n\nError types include `environment_archived`, `agent_archived`, `vault_not_found`, `session_rate_limited`, and `service_unavailable`.\n\nThe outcome of each **scheduled** run (started/succeeded/failed) and each deployment lifecycle change (created/updated/paused/unpaused/archived/deleted) is also delivered as a webhook event — see `shared/managed-agents-webhooks.md` for the `deployment.*` and `deployment_run.*` event types — so you can react without polling. Manual runs do **not** emit `deployment_run.*` webhook events.\n\n## Lifecycle: pause / unpause / archive\n\n| Operation | SDK | Effect |\n|---|---|---|\n| Pause | `client.beta.deployments.pause(id)` | Suppresses scheduled triggers go-forward. Sessions already running continue. **Manual runs are still permitted while paused.** Sets `paused_reason: {\"type\": \"manual\"}`. |\n| Unpause | `client.beta.deployments.unpause(id)` | Resumes from the next scheduled occurrence. **Missed triggers are not backfilled.** Clears `paused_reason`. |\n| Archive | `client.beta.deployments.archive(id)` | **Terminal** — the schedule stops and the deployment can no longer be modified. Use pause for anything reversible. |\n\nRaw HTTP: `POST /v1/deployments/{deployment_id}/pause` (likewise `/unpause`, `/archive`).\n\n### Failure behavior\n\n- **Rate-limited:** recorded immediately as a `session_rate_limited` run, **no retry** — the schedule simply tries again at the next occurrence. (Rate limits on API calls *inside* a session are handled by the session itself.)\n- **Other failed runs** (e.g. `environment_archived`, `vault_not_found`, `service_unavailable`): the run records the `error.type` — monitor runs and fix the referenced resource, or pause the deployment.\n- **Agent archived or deleted:** the deployment is automatically **archived** (terminal) and no further sessions are created.\n\n## Manual runs\n\n`POST /v1/deployments/{deployment_id}/run` (SDK: `client.beta.deployments.run(id)`) creates a session immediately and writes a run with `trigger_context.type: \"manual\"`. Use it to **test a deployment before committing to the schedule** — and remember it works even while the deployment is paused.\n</doc>\n\n<doc path=\"shared/managed-agents-self-hosted-sandboxes.md\">\n# Managed Agents — Self-Hosted Sandboxes\n\nWith `config.type: \"self_hosted\"`, the **agent loop stays on Anthropic's orchestration layer** but **tool execution moves to infrastructure you control** — bash, file ops, and code run inside your container, so filesystem contents and network egress never leave your environment. Contrast with `config.type: \"cloud\"`, where Anthropic runs the container. Connectivity is **outbound-only**: your worker long-polls Anthropic's work queue; Anthropic never dials into your network.\n\n## Flow\n\n```\n1. Create environment: config: {type: \"self_hosted\"} → env_...\n2. Generate environment key (Console, on the environment page) → sk-ant-oat01-... as ANTHROPIC_ENVIRONMENT_KEY\n3. Run a worker: EnvironmentWorker.run() or ant beta:worker poll\n4. Sessions reference environment_id=env_... exactly as for cloud\n```\n\n## Create the environment\n\n```python\nclient = anthropic.Anthropic()\n\nenvironment = client.beta.environments.create(\n name=\"self-hosted\", config={\"type\": \"self_hosted\"}\n)\n```\n\n`{\"type\": \"self_hosted\"}` is the entire config — there are no pool, capacity, or networking sub-fields; you control those on your side.\n\n## Run a worker — SDK (primary path)\n\n`EnvironmentWorker` wraps the poll → dispatch → tool-execute loop. `.run()` is the always-on loop; `.run_one()` / `.runOne()` handles one work item (for webhook-driven wake).\n\n**Python — always-on:**\n\n```python\nimport asyncio\nimport os\nfrom anthropic import AsyncAnthropic\nfrom anthropic.lib.environments import EnvironmentWorker\n\n\nasync def main() -> None:\n environment_key = os.environ[\"ANTHROPIC_ENVIRONMENT_KEY\"]\n environment_id = os.environ[\"ANTHROPIC_ENVIRONMENT_ID\"]\n async with AsyncAnthropic(auth_token=environment_key) as client:\n await EnvironmentWorker(\n client,\n environment_id=environment_id,\n environment_key=environment_key,\n workdir=\"/workspace\",\n ).run()\n\n\nasyncio.run(main())\n```\n\n**TypeScript — always-on:**\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\nimport { EnvironmentWorker } from \"@anthropic-ai/sdk/helpers/beta/environments\";\n\nconst environmentKey = process.env.ANTHROPIC_ENVIRONMENT_KEY!;\nconst environmentId = process.env.ANTHROPIC_ENVIRONMENT_ID!;\nconst client = new Anthropic({ authToken: environmentKey });\nconst ctrl = new AbortController();\nprocess.once(\"SIGTERM\", () => ctrl.abort());\n\nawait new EnvironmentWorker({\n client,\n environmentId,\n environmentKey,\n workdir: \"/workspace\",\n signal: ctrl.signal\n}).run();\n```\n\n**Customizing tools.** `EnvironmentWorker` runs the built-in toolset by default. To add or replace tools, use `AgentToolContext(workdir=, client=, session_id=)` with `beta_agent_toolset(env)` / `betaAgentToolset(env)` and pass the resulting tools to the lower-level `tool_runner()`. Skills attached to the agent are downloaded into `{workdir}/skills/<name>/` before tool calls begin (`AgentToolContext` handles this when given `client` and `session_id`). Downloaded skill files are marked executable automatically by the CLI and SDK; if you implement skills download yourself, you set permissions.\n\n> **Runtime deps:** the SDK helpers require `/bin/bash` at that exact path. The TypeScript SDK additionally requires `unzip`, `tar`, and Node.js 22+. These are resolved at fixed paths and do **not** respect `PATH` overrides.\n\n## Run a worker — `ant` CLI (fixed tools)\n\nThe `ant` CLI ships a worker with the fixed built-in toolset (`bash`, `read`, `write`, `edit`, `glob`, `grep`). Install per `shared/anthropic-cli.md`, then:\n\n```sh\nexport ANTHROPIC_ENVIRONMENT_KEY=sk-ant-oat01-...\nant beta:worker poll --environment-id env_... --workdir /workspace\n```\n\n- `--workdir` is the directory tools operate in (default `.`); tool calls are sandboxed to it.\n- `--environment-key` overrides the env var.\n- `--on-work <script>` runs your script per work item (e.g. to spin a fresh container per session — see Container orchestration below).\n- `--unrestricted-paths`, `--max-idle` (default `60s`), `--log-format` — see `ant beta:worker poll --help`.\n- Flags fall back to env vars (`ANTHROPIC_ENVIRONMENT_ID`, `ANTHROPIC_ENVIRONMENT_KEY`).\n- Exits cleanly on SIGTERM/SIGINT after draining in-flight work.\n- **Fixed toolset** — for custom tools, use the SDK worker above.\n\nInside an `--on-work` container, run `ant beta:worker run --workdir <dir>` as the entrypoint.\n\n## Webhook-driven wake (instead of always-on)\n\nRegister a webhook for `session.status_run_started` (see `shared/managed-agents-webhooks.md`), verify the delivery, then drain one work item with `.run_one()`:\n\n```python\nimport os\nimport anthropic\nfrom anthropic.lib.environments import EnvironmentWorker\n\nenvironment_key = os.environ[\"ANTHROPIC_ENVIRONMENT_KEY\"]\nenvironment_id = os.environ[\"ANTHROPIC_ENVIRONMENT_ID\"]\nclient = anthropic.AsyncAnthropic(\n auth_token=environment_key,\n) # reads ANTHROPIC_WEBHOOK_SIGNING_KEY from env for webhooks.unwrap()\n\n\nasync def handle(raw: bytes, headers: dict[str, str]) -> dict:\n event = client.beta.webhooks.unwrap(raw.decode(), headers=headers)\n if event.data.type != \"session.status_run_started\":\n return {\"status\": \"ignored\"}\n await EnvironmentWorker(\n client,\n environment_id=environment_id,\n environment_key=environment_key,\n workdir=\"/workspace\",\n ).run_one()\n return {\"status\": \"ok\"}\n```\n\nTypeScript: same shape with `client.beta.webhooks.unwrap(body, {headers})` and `new EnvironmentWorker({...}).runOne()`.\n\n## Container orchestration (mid-level)\n\n`EnvironmentWorker.run()` polls and executes tools in the same process. To run each session in its **own** container, use the mid-level poller in a thin orchestrator — Python `client.beta.environments.work.poller(environment_id=, environment_key=, drain=, block_ms=, reclaim_older_than_ms=, auto_stop=)`; TypeScript `new WorkPoller({client, environmentId, environmentKey, autoStop})` from `@anthropic-ai/sdk/helpers/beta/environments` — and, for each yielded `work` item, start a fresh container with these env vars injected, whose entrypoint runs `ant beta:worker run` or an `EnvironmentWorker(...).run_one()`. `block_ms` is 1–999 (or `None` for non-blocking); `reclaim_older_than_ms` re-claims items leased to a dead worker; `drain` stops once the queue is empty; `auto_stop` posts a stop signal after the iterator exits (set `False` when the launched container owns the stop call). **Go's poller has no `auto_stop` opt-out** — it calls `work.Stop` when the handler returns, so block in the handler until the session completes rather than detaching.\n\n| Env var | Value |\n|---|---|\n| `ANTHROPIC_SESSION_ID` | `work.data.id` |\n| `ANTHROPIC_WORK_ID` | `work.id` |\n| `ANTHROPIC_ENVIRONMENT_ID` | `work.environment_id` |\n| `ANTHROPIC_ENVIRONMENT_KEY` | pass through |\n| `ANTHROPIC_BASE_URL` | pass through |\n\nSkip items where `work.data.type != \"session\"`.\n\n## Monitoring & control\n\nThese are **control-plane** calls — authenticate with `x-api-key` (not the environment key); `managed-agents-2026-04-01` beta header. **Call them from outside the worker host** — setting `ANTHROPIC_API_KEY` on the worker host exposes an organization-scoped credential to agent tool calls.\n\n| SDK (`client.beta.environments.work.*`) | REST | CLI | Returns |\n|---|---|---|---|\n| `stats(environment_id)` | `GET /v1/environments/{id}/work/stats` | `ant beta:environments:work stats` | `{type:\"work_queue_stats\", depth, pending, oldest_queued_at, workers_polling}` |\n| `stop(work_id, environment_id=)` | `POST /v1/environments/{id}/work/{work_id}/stop` | `ant beta:environments:work stop` | `work.state` |\n\n## What changes vs `cloud`\n\n| Concern | `cloud` | `self_hosted` |\n|---|---|---|\n| Container lifecycle, hardening, networking | Anthropic | **You** — run non-root, read-only rootfs, drop caps; egress is whatever your VPC/firewall allows |\n| `file` / `github_repository` resource mounting | Anthropic mounts into the container | **You** — pass pointers via `sessions.create(metadata={...})` and have your orchestrator fetch/clone before dispatch |\n| `memory_store` resources | Supported | **Not yet supported** |\n| Vault `environment_variable` credentials | Supported (substituted at Anthropic-managed egress) | **Not yet supported** — egress is yours, so there's nowhere to substitute the secret. Use MCP credentials or a host-side custom tool (`shared/managed-agents-client-patterns.md` Pattern 9) |\n| Built-in tools | Via `agent_toolset_20260401` | Supplied by your worker (`EnvironmentWorker` default / `beta_agent_toolset(env)` / `ant` CLI fixed set) |\n| Skills download | Automatic | `EnvironmentWorker` / `AgentToolContext` fetch into `{workdir}/skills/` (needs `client` + `session_id`) |\n| Claude Platform on AWS | Supported | **Not available** |\n| SDK worker helpers | All SDKs | **Python, TypeScript, Go only** (`EnvironmentWorker` / poller not in Java, Ruby, PHP, or C#) — use one of those three or the `ant` CLI |\n\n## Credentials\n\n| Credential | Format | Scope |\n|---|---|---|\n| `ANTHROPIC_ENVIRONMENT_KEY` | `sk-ant-oat01-...` | One environment's work queue. Generate in Console (\"Generate environment key\"). Pass as `auth_token=` / `authToken` on the client **and** as `environment_key=` / `environmentKey` on `EnvironmentWorker`. Store in a secrets manager; rotate on exposure. |\n| `ANTHROPIC_WEBHOOK_SIGNING_KEY` | `whsec_...` | Webhook signature verification (if using webhook-driven wake). The SDK reads this env var automatically for `client.beta.webhooks.unwrap()`. |\n\n## Security — what you own\n\nContainer hardening; egress restriction (there is no default); `ANTHROPIC_ENVIRONMENT_KEY` custody and rotation; one workspace + environment per trust boundary when running untrusted code; least-privilege for the tool process; log retention and redaction. **Anthropic cannot**: fast-revoke a leaked environment key, verify your image or supply chain, sandbox tool execution inside your container, or enforce retention after tool output reaches your infrastructure. See the Self-Hosted Sandboxes Security page in `shared/live-sources.md` for the full checklist.\n</doc>\n\n<doc path=\"shared/managed-agents-tools.md\">\n# Managed Agents — Tools & Skills\n\n## Tools\n\n### Server tools vs client tools\n\n| Type | Who runs it | How it works |\n|---|---|---|\n| **Prebuilt Claude Agent tools** (`agent_toolset_20260401`) | Anthropic, on the session's container (for `cloud` envs; for `self_hosted`, **your** worker supplies and runs them — see `shared/managed-agents-self-hosted-sandboxes.md`) | File ops, bash, web search, etc. Enable all at once or configure individually with `enabled: true/false`. |\n| **MCP tools** (`mcp_toolset`) | Anthropic's orchestration layer | Capabilities exposed by connected MCP servers. Grant access per-server via the toolset. |\n| **Custom tools** | **You** — your application handles the call and returns results | Agent emits a `agent.custom_tool_use` event, session goes `idle`, you send back a `user.custom_tool_result` event. |\n\n**Recommendation:** Enable all prebuilt tools via `agent_toolset_20260401`, then disable individually as needed.\n\n**Versioning:** The toolset is a versioned, static resource. When underlying tools change, a new toolset version is created (hence `_20260401`) so you always know exactly what you're getting.\n\n### Agent Toolset\n\nThe `agent_toolset_20260401` provides these built-in tools:\n\n| Tool | Description |\n| ---------------------- | ---------------------------------------- |\n| `bash` | Execute bash commands in a shell session |\n| `read` | Read a file from the local filesystem, including text, images, PDFs, and Jupyter notebooks |\n| `write` | Write a file to the local filesystem |\n| `edit` | Perform string replacement in a file |\n| `glob` | Fast file pattern matching using glob patterns |\n| `grep` | Text search using regex patterns |\n| `web_fetch` | Fetch content from a URL |\n| `web_search` | Search the web for information |\n\nEnable the full toolset:\n\n```json\n{\n \"tools\": [\n { \"type\": \"agent_toolset_20260401\" }\n ]\n}\n```\n\n### Per-Tool Configuration\n\nOverride defaults for individual tools. This example enables everything except bash:\n\n```json\n{\n \"tools\": [\n {\n \"type\": \"agent_toolset_20260401\",\n \"default_config\": { \"enabled\": true },\n \"configs\": [\n { \"name\": \"bash\", \"enabled\": false }\n ]\n }\n ]\n}\n```\n\n| Field | Required | Description |\n|---|---|---|\n| `type` | ✅ | `\"agent_toolset_20260401\"` |\n| `default_config` | ❌ | Applied to all tools. `{ \"enabled\": bool, \"permission_policy\": {...} }` |\n| `configs` | ❌ | Per-tool overrides: `[{ \"name\": \"...\", \"enabled\": bool, \"permission_policy\": {...} }]` |\n\n### Permission Policies\n\nControl when server-executed tools (agent toolset + MCP) run automatically vs wait for approval. Does not apply to custom tools.\n\n| Policy | Behavior |\n|---|---|\n| `always_allow` | Tool executes automatically (default) |\n| `always_ask` | Session emits `session.status_idle` and pauses until you send a `tool_confirmation` event |\n\n```json\n{\n \"type\": \"agent_toolset_20260401\",\n \"default_config\": {\n \"enabled\": true,\n \"permission_policy\": { \"type\": \"always_allow\" }\n },\n \"configs\": [\n { \"name\": \"bash\", \"permission_policy\": { \"type\": \"always_ask\" } }\n ]\n}\n```\n\n**Responding to `always_ask`:** Send a `user.tool_confirmation` event with `tool_use_id` from the triggering `agent_tool_use`/`mcp_tool_use` event:\n\n```json\n{ \"type\": \"tool_confirmation\", \"tool_use_id\": \"sevt_abc123\", \"result\": \"allow\" }\n{ \"type\": \"tool_confirmation\", \"tool_use_id\": \"sevt_def456\", \"result\": \"deny\", \"message\": \"Read .env.example instead\" }\n```\n\nThe optional `message` on a deny is delivered to the agent so it can adjust its approach.\n\nTo enable only specific tools, flip the default off and opt-in per tool:\n\n```json\n{\n \"tools\": [\n {\n \"type\": \"agent_toolset_20260401\",\n \"default_config\": { \"enabled\": false },\n \"configs\": [\n { \"name\": \"bash\", \"enabled\": true },\n { \"name\": \"read\", \"enabled\": true }\n ]\n }\n ]\n}\n```\n\n### Custom Tools (Client-Side)\n\nCustom tools are executed by **your application**, not Anthropic. The flow:\n\n1. Agent decides to use the tool → session emits a `agent.custom_tool_use` event with inputs\n2. Session goes `idle` waiting for you\n3. Your application executes the tool\n4. You send back a `user.custom_tool_result` event with the output\n5. Session resumes `running`\n\nNo permission policy needed — you're the one executing.\n\n```json\n{\n \"tools\": [\n {\n \"type\": \"custom\",\n \"name\": \"get_weather\",\n \"description\": \"Fetch current weather for a city.\",\n \"input_schema\": {\n \"type\": \"object\",\n \"properties\": {\n \"city\": { \"type\": \"string\", \"description\": \"City name\" }\n },\n \"required\": [\"city\"]\n }\n }\n ]\n}\n```\n\n### MCP Servers\n\nMCP (Model Context Protocol) servers expose standardized third-party capabilities (e.g. Asana, GitHub, Linear). **Configuration is split across agent and vault:**\n\n1. **Agent creation** declares which servers to connect to (`type`, `name`, `url` — no auth). The agent's `mcp_servers` array has no auth field.\n2. **Vault** stores the OAuth credentials. Attach via `vault_ids` on session create.\n\nThis keeps secrets out of reusable agent definitions. Each vault credential is tied to one MCP server URL; Anthropic matches credentials to servers by URL.\n\n**Agent side — declare servers (no auth):**\n\n| Field | Required | Description |\n|---|---|---|\n| `type` | ✅ | `\"url\"` |\n| `name` | ✅ | Unique name — referenced by `mcp_toolset.mcp_server_name` |\n| `url` | ✅ | The MCP server's endpoint URL (Streamable HTTP transport) |\n\n```json\n{\n \"mcp_servers\": [\n { \"type\": \"url\", \"name\": \"linear\", \"url\": \"https://mcp.linear.app/mcp\" }\n ],\n \"tools\": [\n { \"type\": \"mcp_toolset\", \"mcp_server_name\": \"linear\" }\n ]\n}\n```\n\n**Session side — attach vault:**\n\n```json\n{\n \"agent\": \"agent_abc123\",\n \"environment_id\": \"env_abc123\",\n \"vault_ids\": [\"vlt_abc123\"]\n}\n```\n\n> 💡 **Per-tool enablement (empirical):** `mcp_toolset` has been observed accepting `default_config: {enabled: false}` + `configs: [{name, enabled: true}]` for an allowlist pattern. The API ref shows only the minimal `{type, mcp_server_name}` form.\n\n> 💡 **Changing tools/MCP servers on a running session:** `sessions.update()` can replace `agent.tools`, `agent.mcp_servers`, and `vault_ids` while the session is `idle` — a session-local override that doesn't touch the agent object. See `shared/managed-agents-core.md` → Updating the agent configuration mid-session.\n\n**Large MCP tool outputs.** If an MCP tool returns more than **100K tokens**, the output is automatically offloaded to a file in the sandbox — the agent receives a truncated preview plus the file path and can `read` the full content. No configuration required.\n\n**Invalid vault credentials don't block session creation.** If a vault credential is invalid for a declared MCP server, the session still creates successfully; a `session.error` event describes the MCP auth failure, and auth retries on the next `session.status_idle` → `session.status_running` transition.\n\n> ⚠️ **MCP auth tokens ≠ REST API tokens.** Hosted MCP servers (`mcp.notion.com`, `mcp.linear.app`, etc.) typically require **OAuth bearer tokens**, not the service's native API keys. A Notion `ntn_` integration token authenticates against Notion's REST API but will **not** work as a vault credential for the Notion MCP server. These are different auth systems.\n\n### Vaults — the credential store\n\n**Vaults** store credentials that Anthropic manages on your behalf. Two credential categories:\n\n- **MCP credentials** (`mcp_oauth`, `static_bearer`) — keyed by `mcp_server_url`. When the agent connects to a server at that URL, the token is injected automatically. `mcp_oauth` tokens are auto-refreshed via the standard OAuth 2.0 `refresh_token` grant. This is the only way to authenticate MCP servers.\n- **Environment variables** (`environment_variable`) — keyed by `secret_name` (the env var name). The sandbox sees only an **opaque placeholder**; the real secret is substituted into the outbound request **at egress**. Use this for any service that authenticates through an environment variable: CLIs (`aws`, `gcloud`, `stripe`), SDKs, or direct `curl` calls from the `bash` tool.\n\nSecret fields you supply (`token`, `access_token`, `refresh_token`, `client_secret`, `secret_value`) are write-only — never returned in API responses.\n\n#### Credentials and the sandbox\n\nVaults store credentials; those credentials **never enter the sandbox**. This is a deliberate security boundary — code running in the sandbox (including anything the agent writes) cannot read or exfiltrate a vaulted credential, even under prompt injection. Instead, credentials are injected by Anthropic-side proxies **after** a request leaves the sandbox:\n\n- **MCP tool calls** are routed through an Anthropic-side proxy that fetches the credential from the vault and adds it to the outbound request.\n- **Git operations on attached GitHub repositories** (`git pull`, `git push`, GitHub REST calls) are routed through a git proxy that injects the `github_repository` resource's `authorization_token` the same way.\n- **Environment-variable credentials** appear in the sandbox as an opaque placeholder; the real value replaces the placeholder at egress, on requests to the credential's allowed hosts only.\n\n**When vault credentials don't fit** (e.g. self-hosted sandboxes — `environment_variable` is not yet supported there), **register a custom tool:** the agent emits `agent.custom_tool_use`, your orchestrator (which already holds the credential) executes the call and returns `user.custom_tool_result` over the same authenticated event stream. No public endpoint is exposed; the sandbox never sees the secret. See `shared/managed-agents-client-patterns.md` → Pattern 9.\n\n**Do not put API keys in the system prompt or user messages as a workaround** — they persist in the session's event history.\n\n> Formerly known internally as TATs (Tool/Tenant Access Tokens).\n\n**Flow:**\n\n1. Create a vault (`client.beta.vaults.create(...)`) — one per tenant/user, or one shared, depending on your model\n2. Add credentials to it (`client.beta.vaults.credentials.create(...)`) — MCP credentials are keyed by MCP server URL; environment-variable credentials by `secret_name`\n3. Reference the vault on session create via `vault_ids: [\"vlt_...\"]`\n4. Anthropic auto-refreshes OAuth tokens before they expire and substitutes secrets at runtime\n\n**MCP OAuth credential shape**:\n\n```json\n{\n \"display_name\": \"Notion (workspace-foo)\",\n \"auth\": {\n \"type\": \"mcp_oauth\",\n \"mcp_server_url\": \"https://mcp.notion.com/mcp\",\n \"access_token\": \"<current access token>\",\n \"expires_at\": \"2026-04-02T14:00:00Z\",\n \"refresh\": {\n \"refresh_token\": \"<refresh token>\",\n \"client_id\": \"<your OAuth client_id>\",\n \"token_endpoint\": \"https://api.notion.com/v1/oauth/token\",\n \"token_endpoint_auth\": { \"type\": \"none\" }\n }\n }\n}\n```\n\nThe `refresh` block is what enables auto-refresh — `token_endpoint` is where Anthropic posts the `refresh_token` grant. `token_endpoint_auth` is a discriminated union:\n\n| `type` | Shape | Use when |\n|---|---|---|\n| `\"none\"` | `{type: \"none\"}` | Public OAuth client (no secret) |\n| `\"client_secret_basic\"` | `{type: \"client_secret_basic\", client_secret: \"...\"}` | Confidential client, secret via HTTP Basic auth |\n| `\"client_secret_post\"` | `{type: \"client_secret_post\", client_secret: \"...\"}` | Confidential client, secret in request body |\n\nOmit `refresh` entirely if you only have an access token with no refresh capability — it'll work until it expires, then the agent loses access.\n\n> 💡 **Getting an OAuth token.** How you obtain the initial access and refresh tokens depends on the MCP server — consult its documentation. Once you have them, store them in a vault credential using the shape above; Anthropic auto-refreshes via the `refresh.token_endpoint` from there.\n\n**Environment-variable credential shape**:\n\n```json\n{\n \"display_name\": \"Twilio API key for sandbox\",\n \"auth\": {\n \"type\": \"environment_variable\",\n \"secret_name\": \"TWILIO_API_KEY\",\n \"secret_value\": \"sk-your-secret-here\",\n \"networking\": {\n \"type\": \"limited\",\n \"allowed_hosts\": [\"api.twilio.com\", \"*.twilio.com\"]\n }\n }\n}\n```\n\n`networking.allowed_hosts` controls which outbound hosts the secret can be substituted for — `{\"type\": \"limited\", \"allowed_hosts\": [...]}` or `{\"type\": \"unrestricted\"}` if you can't enumerate the domains in advance. Limiting is strongly recommended: it prevents the key from ever being sent to unauthorized hosts.\n\n**`injection_location`** (optional, sibling of `networking`) controls **where** in the outbound request the secret is substituted — `{header: bool, body: bool}`. The two are independent: `allowed_hosts` scopes *which hosts* a substituted request can target; `injection_location` scopes *which parts of the request* the secret is substituted into across all of those hosts. Most services read an API key from a request header, so `{\"header\": true}` is the narrower configuration — request bodies are often assembled from content the agent is working with, making the body the broader exposure surface. A placeholder in a disabled location is **neither substituted nor stripped** — the literal opaque placeholder string is sent to the third party in that location.\n\n| Operation | `injection_location` semantics |\n|---|---|\n| Create credential | Omit the field entirely → both locations enabled. Provide the object → any field you omit defaults to `false` (`{\"header\": true}` creates a header-only credential). |\n| Update credential | Fields **merge individually** — `{\"body\": false}` disables body substitution and leaves `header` unchanged. For a running session, the update takes effect on the session's next operation. |\n\nA credential must have at least one location enabled; a create or update that would disable both returns 400, as does explicit `null` for the object or either field (omit instead). The response always returns both fields with their resolved values.\n\n> ⚠️ **Two networking layers, both required.** `networking.allowed_hosts` on the credential controls which requests *use the secret*, not which requests are *allowed*. The agent must also be able to reach the domain at the **environment level** (`unrestricted`, or the host listed in the environment's `allowed_hosts` — see `shared/managed-agents-environments.md`). A domain missing from either layer means the secret-substituted request fails.\n\n> ⚠️ **Client-side validation caveat.** Substitution happens at egress, not inside the sandbox — clients that validate the credential *format* locally before making a network request (e.g. a CLI that checks the key starts with `sk-`) will see the opaque placeholder and may fail at startup. If a client rejects the credential before any network call, that's why.\n\n> 💡 **Scope the key minimally.** The agent can do anything the key allows; a key with broader permissions than the task needs increases the blast radius if the agent behaves unexpectedly.\n\n**Not supported with self-hosted sandboxes** — `environment_variable` credentials require Anthropic-managed egress. See `shared/managed-agents-self-hosted-sandboxes.md`.\n\n**Constraints (all credential types):**\n\n- **Unique key per vault.** `mcp_server_url` (MCP credentials) and `secret_name` (environment-variable credentials) must be unique among active credentials in a vault; duplicates return a 409.\n- **Keys are immutable.** Secret values, `display_name`, and (on environment-variable credentials) `injection_location` can be updated; to change `mcp_server_url`, `secret_name`, `token_endpoint`, or `client_id`, archive the credential and create a new one. Archiving purges the secret and frees the key for a replacement.\n- **Maximum 20 credentials per vault.**\n- Credentials are stored as provided and **not validated until session runtime** — an invalid credential surfaces as an authentication or downstream error during the session, which is emitted but does not block the session from continuing.\n\n**Scoping:** Vaults are workspace-scoped. Anyone with developer+ role in the API workspace can create, read (metadata only — secrets are write-only), and attach vaults. `vault_ids` can be set at session **create** time but not via session update (the SDK docstring says \"Not yet supported; requests setting this field are rejected\").\n\n---\n\n## Skills\n\nSkills are reusable, filesystem-based resources that provide your agent with domain-specific expertise: workflows, context, and best practices that transform general-purpose agents into specialists. Unlike prompts (conversation-level instructions for one-off tasks), skills load on-demand and eliminate the need to repeatedly provide the same guidance across multiple conversations.\n\nTwo types — both work the same way; the agent automatically uses them when relevant to the task at hand:\n\n| Type | What it is |\n|---|---|\n| **Pre-built Anthropic skills** | Common document tasks (PowerPoint, Excel, Word, PDF). Reference by name (e.g. `xlsx`). |\n| **Custom skills** | Skills you've created in your organization via the Skills API. Reference by `skill_id` + optional `version`. |\n\n**Max 20 skills per agent.** Agent creation uses `managed-agents-2026-04-01`; the separate Skills API (for managing custom skill definitions) uses `skills-2025-10-02`.\n\n### Enabling skills on a session\n\nSkills are attached to the **agent** definition via `agents.create()`:\n\n```ts\nconst agent = await client.beta.agents.create(\n {\n name: \"Financial Agent\",\n model: \"claude-opus-4-8\",\n system: \"You are a financial analysis agent.\",\n skills: [\n { type: \"anthropic\", skill_id: \"xlsx\" },\n { type: \"custom\", skill_id: \"skill_abc123\", version: \"latest\" },\n ],\n }\n);\n```\n\nPython:\n\n```python\nagent = client.beta.agents.create(\n name=\"Financial Agent\",\n model=\"claude-opus-4-8\",\n system=\"You are a financial analysis agent.\",\n skills=[\n {\"type\": \"anthropic\", \"skill_id\": \"xlsx\"},\n {\"type\": \"custom\", \"skill_id\": \"skill_abc123\", \"version\": \"latest\"},\n ]\n)\n```\n\n**Skill reference fields:**\n\n| Field | Anthropic skill | Custom skill |\n|---|---|---|\n| `type` | `\"anthropic\"` | `\"custom\"` |\n| `skill_id` | Skill name (e.g. `\"xlsx\"`, `\"docx\"`, `\"pptx\"`, `\"pdf\"`) | Skill ID from Skills API (e.g. `\"skill_abc123\"`) |\n| `version` | — | `\"latest\"` or a specific version number |\n\n### Skills API\n\n| Operation | Method | Path |\n| --------------------- | -------- | ----------------------------------------------- |\n| Create Skill | `POST` | `/v1/skills` |\n| List Skills | `GET` | `/v1/skills` |\n| Get Skill | `GET` | `/v1/skills/{id}` |\n| Delete Skill | `DELETE` | `/v1/skills/{id}` |\n| Create Version | `POST` | `/v1/skills/{id}/versions` |\n| List Versions | `GET` | `/v1/skills/{id}/versions` |\n| Get Version | `GET` | `/v1/skills/{id}/versions/{version}` |\n| Delete Version | `DELETE` | `/v1/skills/{id}/versions/{version}` |\n</doc>\n\n<doc path=\"shared/managed-agents-webhooks.md\">\n# Managed Agents — Webhooks\n\nAnthropic can POST to your HTTPS endpoint when a Managed Agents resource changes state — an alternative to holding an SSE stream or polling. Payloads are **thin** (event type + resource IDs only); on receipt, fetch the resource for current state. Every delivery is HMAC-signed.\n\n> **Direction matters.** This page covers *Anthropic → you* notifications about session/vault state. It does **not** cover *third-party → you* webhooks that *trigger* a session (e.g. a GitHub push handler that calls `sessions.create()`) — that's ordinary application code on your side with no Anthropic-specific wire format.\n\n---\n\n## Register an endpoint (Console only)\n\nConsole → **Manage → Webhooks**. There is no programmatic endpoint-management API yet. Secret rotation is supported from the same page.\n\n| Field | Constraint |\n|---|---|\n| URL | HTTPS on port 443, publicly resolvable hostname |\n| Event types | Subscribe per `data.type` — you only receive subscribed types (plus test events) |\n| Signing secret | `whsec_`-prefixed, 32 bytes, **shown once at creation** — store it |\n\n---\n\n## Verify the signature\n\nEvery delivery is HMAC-signed. **Use the SDK's `client.beta.webhooks.unwrap()`** — it verifies the signature, rejects payloads more than ~5 minutes old, and returns the parsed event. It reads the `whsec_` secret from `ANTHROPIC_WEBHOOK_SIGNING_KEY`.\n\n```python\nimport anthropic\nfrom flask import Flask, request\n\nclient = anthropic.Anthropic() # reads ANTHROPIC_WEBHOOK_SIGNING_KEY from env\napp = Flask(__name__)\n\n\n@app.route(\"/webhook\", methods=[\"POST\"])\ndef webhook():\n try:\n event = client.beta.webhooks.unwrap(\n request.get_data(as_text=True),\n headers=dict(request.headers),\n )\n except Exception:\n return \"invalid signature\", 400\n\n if event.id in seen_event_ids: # dedupe retries — id is per-event, not per-delivery\n return \"\", 204\n seen_event_ids.add(event.id)\n\n match event.data.type:\n case \"session.status_idled\":\n session = client.beta.sessions.retrieve(event.data.id)\n notify_user(session)\n case \"vault_credential.refresh_failed\":\n alert_oncall(event.data.id)\n\n return \"\", 204\n```\n\nPass the **raw request body** to `unwrap()` — frameworks that re-serialize JSON (Express `.json()`, Flask `.get_json()`) change the bytes and break the MAC. For other languages, look up the `beta.webhooks.unwrap` binding in the SDK repo (`shared/live-sources.md`); don't hand-roll verification.\n\n---\n\n## Payload envelope\n\n```json\n{\n \"type\": \"event\",\n \"id\": \"event_01ABC...\",\n \"created_at\": \"2026-03-18T14:05:22Z\",\n \"data\": {\n \"type\": \"session.status_idled\",\n \"id\": \"session_01XYZ...\",\n \"organization_id\": \"8a3d2f1e-...\",\n \"workspace_id\": \"c7b0e4d9-...\"\n }\n}\n```\n\nSwitch on `data.type`, fetch the resource by `data.id`, return any **2xx** to acknowledge. `created_at` is when the *state transition* happened, not when the webhook fired.\n\n---\n\n## Supported `data.type` values\n\n| `data.type` | Fires when |\n|---|---|\n| `session.status_scheduled` | Session created and ready to accept events |\n| `session.status_run_started` | Agent execution kicked off (every transition to `running`) |\n| `session.status_idled` | Agent awaiting input (tool approval, custom tool result, or next message) |\n| `session.status_terminated` | Session hit a terminal error |\n| `session.thread_created` | Multiagent: coordinator opened a new subagent thread |\n| `session.thread_idled` | Multiagent: a subagent thread is waiting for input |\n| `session.outcome_evaluation_ended` | Outcome grader finished one iteration |\n| `vault.archived` | Vault was archived |\n| `vault.created` | Vault was created |\n| `vault.deleted` | Vault was deleted |\n| `vault_credential.archived` | Vault credential was archived |\n| `vault_credential.created` | Vault credential was created |\n| `vault_credential.deleted` | Vault credential was deleted |\n| `vault_credential.refresh_failed` | MCP OAuth vault credential failed to refresh |\n| `agent.created` | Agent created |\n| `agent.updated` | A new agent version was published. Updates that do not create a new version do **not** fire this. |\n| `agent.archived` | Agent archived |\n| `agent.deleted` | Agent permanently deleted — no object left to fetch; treat the event itself as final |\n| `deployment.created` | Scheduled deployment created |\n| `deployment.updated` | Deployment properties changed (e.g. schedule edited) |\n| `deployment.paused` | Deployment paused — by request, or automatically when a scheduled run fails with a **non-recoverable** error (archived agent, missing environment). Recoverable failures, including rate limits, do **not** auto-pause. |\n| `deployment.unpaused` | Deployment unpaused; schedule resumes |\n| `deployment.archived` | Deployment archived — directly, or as a result of agent archival/deletion |\n| `deployment.deleted` | Deployment permanently deleted — no object left to fetch; treat the event itself as final |\n| `deployment_run.started` | A **scheduled** run started. Manual runs do **not** emit `deployment_run.*` events. |\n| `deployment_run.succeeded` | Scheduled run created its session. Same `data.id` (the run ID) as the run's `.started` event — fetch the deployment run for its `session_id`, then subscribe to the session events to follow the work. |\n| `deployment_run.failed` | Scheduled run did not create a session. Same `data.id` as the run's `.started` event — fetch the deployment run for `error.type` / `error.message`. |\n\n> These are **webhook** `data.type` values — a separate namespace from SSE event types (`session.status_idle`, `span.outcome_evaluation_end`, etc. in `shared/managed-agents-events.md`). Don't reuse SSE constants in webhook handlers.\n\n---\n\n## Delivery behavior & pitfalls\n\n- **No ordering guarantee.** `session.status_idled` may arrive before `session.outcome_evaluation_ended` even if the evaluation finished first. Sort by envelope `created_at` if order matters.\n- **Retries carry the same `event.id`.** At least one retry on non-2xx. Dedupe on `event.id`.\n- **3xx is failure.** Redirects are not followed — update the URL in Console if your endpoint moves.\n- **Auto-disable** after ~20 consecutive failed deliveries, or immediately if the hostname resolves to a private IP or returns a redirect. Re-enable manually in Console.\n- **Thin payload is intentional.** Don't expect `stop_reason`, `outcome_evaluations`, credential secrets, etc. on the webhook body — fetch the resource.\n</doc>\n\n<doc path=\"shared/model-migration.md\">\n# Model Migration Guide\n\n> **If you arrived via `/claude-api migrate`:** this is the right file. Execute the steps below in order — do not summarize them back to the user. Start with Step 0 (confirm scope) before touching any file.\n\nHow to move existing code to newer Claude models. Covers breaking changes, deprecated parameters, and drop-in replacements for retired models.\n\nFor the latest, authoritative version (with code samples in every supported language), WebFetch the **Migration Guide** URL from `shared/live-sources.md`. Use this file for the consolidated, skill-resident reference; fall back to the live docs whenever a model launch or breaking change may have shifted the picture.\n\n**This file is large.** Use the section names below to jump (or `Grep` this file for the heading text). Read Step 0 and Step 1 first — they apply to every migration. Then read only the per-target section for the model you are migrating to.\n\n| Section | When you need it |\n|---|---|\n| Step 0: Confirm the migration scope | Always — before any edits |\n| Step 1: Classify each file | Always — decides whether to swap, add-alongside, or skip |\n| Per-SDK Syntax Reference | Translate the Python examples in this guide to TypeScript / Go / Ruby / Java / C# / PHP |\n| Destination Models / Retired Model Replacements | Picking a target model |\n| Breaking Changes by Source Model | Migrating to Opus 4.6 / Sonnet 4.6 |\n| Migrating to Opus 4.7 | Migrating to Opus 4.7 (breaking changes, silent defaults, behavioral shifts) |\n| Opus 4.7 Migration Checklist | The required vs optional items for 4.7, tagged `[BLOCKS]` / `[TUNE]` |\n| Migrating to Opus 4.8 | Migrating to Opus 4.8 (no new breaking changes; mid-session system prompts; behavioral re-tuning) |\n| Opus 4.8 Migration Checklist | The required vs optional items for 4.8, tagged `[BLOCKS]` / `[TUNE]` |\n| Migrating to Claude Sonnet 5 | Migrating Sonnet 4.6 → Claude Sonnet 5 (adaptive thinking on by default; non-default sampling params 400; new tokenizer; `xhigh` effort for coding/agentic; high-res vision; behavioral re-tuning) |\n| Claude Sonnet 5 Migration Checklist | The required vs optional items, tagged `[BLOCKS]` / `[TUNE]` |\n| Migrating to Claude Fable 5 | Migrating to Claude Fable 5 or Claude Mythos 5 (always-on thinking, raw chain of thought never returned, refusal handling, data retention, behavioral shifts + prompting guidance) |\n| Claude Fable 5 Migration Checklist | The required vs optional items for Claude Fable 5, tagged `[BLOCKS]` / `[TUNE]` |\n| Verify the Migration | After edits — runtime spot-check |\n\n**TL;DR:** Change the model ID string. If you were using `budget_tokens`, switch to `thinking: {type: \"adaptive\"}`. If you were using assistant prefills, they 400 on both Opus 4.6 and Sonnet 4.6 — switch to one of the prefill replacements (most often `output_config.format`; see the table in Breaking Changes by Source Model). If you're moving from Sonnet 4.5 to Sonnet 4.6, set `effort` explicitly — 4.6 defaults to `high`. Remove the `effort-2025-11-24` and `fine-grained-tool-streaming-2025-05-14` beta headers (GA on 4.6); remove `interleaved-thinking-2025-05-14` once you're on adaptive thinking (keep it only while using the transitional `budget_tokens` escape hatch). Then drop back from `client.beta.messages.create` to `client.messages.create`. Dial back any aggressive \"CRITICAL: YOU MUST\" tool instructions; 4.6 follows the system prompt much more closely.\n\n---\n\n## Step 0: Confirm the migration scope\n\n**Before any Write, Edit, or MultiEdit call, confirm the scope.** If the user's request does not explicitly name a single file, a specific directory, or an explicit file list, **ask first — do not start editing**. This is non-negotiable: even imperative-sounding requests like \"migrate my codebase\", \"move my project to X\", \"upgrade to Sonnet 4.6\", or bare \"migrate to Opus 4.7\" leave the scope ambiguous and require a clarifying question. Phrases like \"my project\", \"my code\", \"my codebase\", \"the whole thing\", \"everywhere\", or \"across the repo\" are **ambiguous, not directive** — they tell you *what* to do but not *where*. Ask before doing.\n\nOffer the common scopes explicitly and wait for the answer before touching any file:\n\n1. The entire working directory\n2. A specific subdirectory (e.g. `src/`, `app/`, `services/billing/`)\n3. A specific file or a list of files\n\nSurface this as a single clarifying question so the user can answer in one turn. **Proceed without asking only when the scope is already unambiguous** — the user named an exact file (\"migrate `extract.py` to Sonnet 4.6\"), pointed at a specific directory (\"migrate everything under `services/billing/` to Opus 4.6\"), listed specific files (\"update `a.py` and `b.py`\"), or already answered the scope question in an earlier turn. If you can answer the question \"which files is this change going to touch?\" with a precise list from the prompt alone, proceed. If not, ask.\n\n**Worked example.** If the user says *\"Move my project to Opus 4.6. I want adaptive thinking everywhere it makes sense.\"* you do not know whether \"my project\" means the whole working directory, just `src/`, just the production code, or something else — the `everywhere` makes the intent clear (update every call site *within scope*) but the scope itself is still not defined. Do not start editing. Respond with:\n\n> Before I start editing, can you confirm the scope? I can migrate:\n> 1. Every `.py` file in the working directory\n> 2. Just the files under `src/` (production code)\n> 3. A specific subdirectory or list of files you name\n>\n> Which one?\n\nThen wait for the answer. The same applies to *\"Migrate to Opus 4.7\"* and bare *\"Help me upgrade to Sonnet 4.6\"* — ask before editing.\n\n**Sizing the scope question (large repos).** Before asking, get a per-directory count so the user can pick concretely:\n\n```sh\nrg -l \"<old-model-id>\" --type-not md | cut -d/ -f1 | sort | uniq -c | sort -rn\n```\n\nPresent the breakdown in your scope question (e.g. *\"Found 217 references across 3 directories: api/ (130), api-go/ (62), routing/ (25). Which to migrate?\"*). Also confirm `git status` is clean before surveying — unexpected modifications mean a concurrent process; stop and investigate before proceeding.\n\n---\n\n## Step 1: Classify each file\n\nNot every file that contains the old model ID is a **caller** of the API. Before editing, classify each file into one of these buckets — the right action differs:\n\n| # | Bucket | What it looks like | Action |\n|---|---|---|---|\n| 1 | **Calls the API/SDK** | `client.messages.create(model=…)`, `anthropic.Anthropic()`, request payloads | Swap the model ID **and** apply the breaking-change checklist for the target version (below). |\n| 2 | **Defines or serves the model** | Model registries, OpenAPI specs, routing/queue configs, model-policy enums, generated catalogs | The old entry **stays** (the model is still served). Ask whether to (a) add the new model alongside, (b) leave alone, or (c) retire the old model — never blind-replace. **If you can't ask, default to (a): add the new model alongside and flag it** — replacing would de-register a model that's still in production. |\n| 3 | **References the ID as an opaque string** | UI fallback constants, capability-gate substring checks, generic test fixtures, label parsers, env defaults | Usually swap the string and verify any parser/regex/substring match handles the new ID — but check the sub-cases below first. |\n| 4 | **Suffixed variant ID** | `claude-<model>-<suffix>` like `-fast`, `-1024k`, `-200k`, `[1m]`, dated snapshots | These are deployment/routing identifiers, not the public model ID. **Do not assume a new-model equivalent exists.** Verify in the registry first; if absent, leave the string alone and flag it. **Exception: `-fast` strings (e.g. `claude-opus-4-6-fast`) are handled by the Fast Mode section below**, which rewrites them to Opus 4.8 plus `speed=\"fast\"` and the `fast-mode-2026-02-01` beta rather than leaving them in place. |\n\n**Bucket 3 sub-cases — before swapping a string reference, check:**\n\n- **Capability gate** (e.g. `if 'opus-4-6' in model_id:` enables a feature) → **add the new ID alongside**, don't replace. The old model is still served and still has the capability, so replacing would silently disable the feature for any old-model traffic that still flows through. If you know no old-model traffic will hit this gate (single-caller codebase fully migrating), replacing is fine; if unsure, add alongside.\n- **Registry-assert test** (e.g. `assert \"claude-X\" in supported_models`, `test_X_has_N_clusters`) → **add an assertion for the new model alongside; keep the old one.** The old model is still served, so its assertion stays valid — but the registry should also include the new model, so assert that too. Heuristic: if the test references multiple model versions in a list, it's a registry test; if one model in a struct compared only to itself, it's a generic fixture.\n- **Frozen / generated snapshot** → **regenerate**, don't hand-edit.\n- **Coupled to a definer** (e.g. an integration test that passes model authorization via a shared `conftest` seed list, or asserts on a billing-tier / rate-limit-group enum or a generated SKU/pricing catalog) → **verify the definer has a new-model entry first.** If not, add a seed entry (reusing the nearest existing tier as a placeholder); if you can't confidently do that, ask the user how to populate the definer. **Do not skip the test.** Swapping without populating the definer will make the test fail at runtime.\n\nWhen migrating tests specifically: breaking parameters (`temperature`, `top_p`, `budget_tokens`) are usually absent — test fixtures rarely set sampling params on placeholder models. The breaking-change scan is still required, but expect mostly clean results.\n\n**Find intentionally-flagged sync points first.** Many codebases tag spots that must change at every model launch with comment markers like `MODEL LAUNCH`, `KEEP IN SYNC`, `@model-update`, or similar. Grep for whatever convention the repo uses *before* the broad model-ID grep — those markers point at the load-bearing changes.\n\n---\n\n## Per-SDK Syntax Reference\n\nCode examples in this guide are Python. **The same fields exist in every official Anthropic SDK** — Stainless generates all 7 from the same OpenAPI spec, so JSON field names map 1:1 with only case-convention differences. Use the rows below to translate the Python examples to the SDK you are migrating.\n\n> **Verify type and method names against the SDK source before writing them into customer code.** WebFetch the relevant repository from the SDK source-code table in `shared/live-sources.md` (one row per SDK) and confirm the exact symbol — particularly for typed SDKs (Go, Java, C#) where union/builder names can differ from the JSON shape. Do not guess type names that aren't in the table below or in `<lang>/claude-api/README.md`.\n\n\n### `thinking` — `budget_tokens` → adaptive\n\n| SDK | Before | After |\n|---|---|---|\n| Python | `thinking={\"type\": \"enabled\", \"budget_tokens\": N}` | `thinking={\"type\": \"adaptive\"}` |\n| TypeScript | `thinking: { type: 'enabled', budget_tokens: N }` | `thinking: { type: 'adaptive' }` |\n| Go | `Thinking: anthropic.ThinkingConfigParamOfEnabled(N)` | `Thinking: anthropic.ThinkingConfigParamUnion{OfAdaptive: &anthropic.ThinkingConfigAdaptiveParam{}}` |\n| Ruby | `thinking: { type: \"enabled\", budget_tokens: N }` | `thinking: { type: \"adaptive\" }` |\n| Java | `.thinking(ThinkingConfigEnabled.builder().budgetTokens(N).build())` | `.thinking(ThinkingConfigAdaptive.builder().build())` |\n| C# | `Thinking = new ThinkingConfigEnabled { BudgetTokens = N }` | `Thinking = new ThinkingConfigAdaptive()` |\n| PHP | `thinking: ['type' => 'enabled', 'budget_tokens' => N]` | `thinking: ['type' => 'adaptive']` |\n\n### Sampling parameters — `temperature` / `top_p` / `top_k`\n\n(Remove the field entirely on Opus 4.7; on Claude 4.x keep at most one of `temperature` or `top_p`.)\n\n| SDK | Field(s) to remove |\n|---|---|\n| Python | `temperature=…`, `top_p=…`, `top_k=…` |\n| TypeScript | `temperature: …`, `top_p: …`, `top_k: …` |\n| Go | `Temperature: anthropic.Float(…)`, `TopP: anthropic.Float(…)`, `TopK: anthropic.Int(…)` |\n| Ruby | `temperature: …`, `top_p: …`, `top_k: …` |\n| Java | `.temperature(…)`, `.topP(…)`, `.topK(…)` |\n| C# | `Temperature = …`, `TopP = …`, `TopK = …` |\n| PHP | `temperature: …`, `topP: …`, `topK: …` |\n\n### Prefill replacement — structured outputs via `output_config.format`\n\n| SDK | Remove (last assistant turn) | Add |\n|---|---|---|\n| Python | `{\"role\": \"assistant\", \"content\": \"…\"}` | `output_config={\"format\": {\"type\": \"json_schema\", \"schema\": SCHEMA}}` |\n| TypeScript | `{ role: 'assistant', content: '…' }` | `output_config: { format: { type: 'json_schema', schema: SCHEMA } }` |\n| Go | trailing `anthropic.MessageParam{Role: \"assistant\", …}` | `OutputConfig: anthropic.OutputConfigParam{Format: anthropic.JSONOutputFormatParam{…}}` |\n| Ruby | `{ role: \"assistant\", content: \"…\" }` | `output_config: { format: { type: \"json_schema\", schema: SCHEMA } }` |\n| Java | trailing `Message.builder().role(ASSISTANT)…` | `.outputConfig(OutputConfig.builder().format(JsonOutputFormat.builder()…build()).build())` |\n| C# | trailing `new Message { Role = \"assistant\", … }` | `OutputConfig = new OutputConfig { Format = new JsonOutputFormat { … } }` |\n| PHP | trailing `['role' => 'assistant', 'content' => '…']` | `outputConfig: ['format' => ['type' => 'json_schema', 'schema' => $SCHEMA]]` |\n\n### `thinking.display` — opt back into summarized reasoning (Opus 4.7)\n\n| SDK | Add |\n|---|---|\n| Python | `thinking={\"type\": \"adaptive\", \"display\": \"summarized\"}` |\n| TypeScript | `thinking: { type: 'adaptive', display: 'summarized' }` |\n| Go | `Thinking: anthropic.ThinkingConfigParamUnion{OfAdaptive: &anthropic.ThinkingConfigAdaptiveParam{Display: anthropic.ThinkingConfigAdaptiveDisplaySummarized}}` |\n| Ruby | `thinking: { type: \"adaptive\", display: \"summarized\" }` (or `display_:` when constructing the model class directly) |\n| Java | `.thinking(ThinkingConfigAdaptive.builder().display(ThinkingConfigAdaptive.Display.SUMMARIZED).build())` |\n| C# | `Thinking = new ThinkingConfigAdaptive { Display = Display.Summarized }` |\n| PHP | `thinking: ['type' => 'adaptive', 'display' => 'summarized']` |\n\nFor any field not in these tables, the JSON key in the Python example translates directly: `snake_case` for Python/TypeScript/Ruby, `camelCase` named args for PHP, `PascalCase` struct fields for Go/C#, `camelCase` builder methods for Java.\n\n---\n\n## Explain every change you make\n\nMigration edits often look arbitrary to a user who hasn't read the release notes — a removed `temperature`, a deleted prefill, a rewritten system-prompt sentence. **For each edit, tell the user what you changed and why**, tied to the specific API or behavioral change that motivates it. Do this in your summary as you work, not just at the end.\n\nBe especially explicit about **system-prompt edits**. Users are rightly protective of their prompts, and prompt-tuning changes are judgment calls (not hard API requirements). For any prompt edit:\n\n- Quote the before and after text.\n- State the behavioral shift that motivates it (e.g. *\"Opus 4.7 calibrates response length to task complexity, so I added an explicit length instruction\"*, or *\"4.6 follows instructions more literally, so 'CRITICAL: YOU MUST use the search tool' will now overtrigger — softened to 'Use the search tool when…'\"*).\n- Make clear which prompt edits are **optional tuning** (tone, length, subagent guidance) versus which code edits are **required to avoid a 400** (sampling params, `budget_tokens`, prefills). Never present an optional prompt change as mandatory.\n\nIf you're applying several prompt-tuning edits at once, offer them as a short list the user can accept or decline item-by-item rather than silently rewriting their system prompt.\n\n---\n\n## Before You Migrate\n\n1. **Confirm the target model ID.** Use only the exact strings from `shared/models.md` — do not append date suffixes to aliases (`claude-opus-4-6`, not `claude-opus-4-6-20251101`). Guessing an ID will 404.\n2. **Check which features your code uses** with this checklist:\n - `thinking: {type: \"enabled\", budget_tokens: N}` → migrate to adaptive thinking on Opus 4.6 / Sonnet 4.6 (still functional but deprecated)\n - Assistant-turn prefills (`messages` ending with `role: \"assistant\"`) → must change on Opus 4.6 / Sonnet 4.6 (returns 400)\n - `output_format` parameter on `messages.create()` → must change on all models (deprecated API-wide)\n - `max_tokens > ~16000` → must stream on any model (above ~16K risks SDK HTTP timeouts). When streaming, every current model reaches 128K except Haiku 4.5, which caps at 64K\n - Beta headers `effort-2025-11-24`, `fine-grained-tool-streaming-2025-05-14`, `interleaved-thinking-2025-05-14` → GA on 4.6, remove them and switch from `client.beta.messages.create` to `client.messages.create`\n - Moving Sonnet 4.5 → Sonnet 4.6 with no `effort` set → 4.6 defaults to `high`, which may change your latency/cost profile\n - System prompts with `CRITICAL`, `MUST`, `If in doubt, use X` language → likely to overtrigger on 4.6 (see Prompt-Behavior Changes)\n - Coming from 3.x / 4.0 / 4.1: also check sampling params (`temperature` + `top_p`), tool versions (`text_editor_20250728`), `refusal` + `model_context_window_exceeded` stop reasons, trailing-newline tool-param handling\n3. **Test on a single request first.** Run one call against the new model, inspect the response, then roll out.\n\n---\n\n## Destination Models (recommended targets)\n\n| If you're on… | Migrate to | Why |\n| ------------------------------------- | ------------------ | ------------------------------------------------- |\n| Claude Mythos Preview (`claude-mythos-preview`) | `claude-mythos-5` (Project Glasswing successor) or `claude-fable-5` (GA) | Same tokenizer family — mostly a model-ID swap; remove `thinking` config and prefill; see Migrating to Claude Fable 5 |\n| Opus 4.7 | `claude-opus-4-8` | Most capable Opus-tier model; same API surface as 4.7 (no new breaking changes) — mostly prompt re-tuning; see Migrating to Opus 4.8 |\n| Opus 4.6 | `claude-opus-4-8` | Apply the Opus 4.7 breaking changes, then the 4.8 re-tuning |\n| Opus 4.0 / 4.1 / 4.5 / Opus 3 | `claude-opus-4-8` | Apply 4.6 → 4.7 → 4.8 in order (adaptive thinking, drop sampling params, then re-tune) |\n| Sonnet 4.6 | `claude-sonnet-5` | Near-Opus quality on agentic and coding work at Sonnet cost; adaptive thinking on by default; see Migrating to Claude Sonnet 5 |\n| Sonnet 4.0 / 4.5 / 3.7 / 3.5 | `claude-sonnet-5` | Apply the Sonnet 4.6 changes first, then the Claude Sonnet 5 section |\n| Haiku 3 / 3.5 | `claude-haiku-4-5` | Fastest and most cost-effective |\n\nDefault to the latest Opus for the caller's tier unless they explicitly chose otherwise. The Opus migrations layer: if you're on Opus 4.6 or older, apply each version's section in order up to your target (e.g. 4.5 → 4.8 means the 4.6, 4.7, and 4.8 sections in sequence). A 4.7 → 4.8 move has no new breaking changes — see Migrating to Opus 4.8 below.\n\n---\n\n## Retired Model Replacements\n\nThese models return 404 — update immediately:\n\n| Retired model | Retired | Drop-in replacement |\n| ----------------------------- | ------------- | -------------------- |\n| `claude-3-7-sonnet-20250219` | Feb 19, 2026 | `claude-sonnet-5` |\n| `claude-3-5-haiku-20241022` | Feb 19, 2026 | `claude-haiku-4-5` |\n| `claude-3-opus-20240229` | Jan 5, 2026 | `claude-opus-4-8` |\n| `claude-3-5-sonnet-20241022` | Oct 28, 2025 | `claude-sonnet-5` |\n| `claude-3-5-sonnet-20240620` | Oct 28, 2025 | `claude-sonnet-5` |\n| `claude-3-sonnet-20240229` | Jul 21, 2025 | `claude-sonnet-5` |\n| `claude-2.1`, `claude-2.0` | Jul 21, 2025 | `claude-sonnet-5` |\n\n## Deprecated Models (retiring soon)\n\n| Model | Retires | Replacement |\n| ----------------------------- | ------------- | -------------------- |\n| `claude-3-haiku-20240307` | Apr 19, 2026 | `claude-haiku-4-5` |\n| `claude-opus-4-20250514` | June 15, 2026 | `claude-opus-4-8` |\n| `claude-sonnet-4-20250514` | June 15, 2026 | `claude-sonnet-5` |\n\n---\n\n## Breaking Changes by Source Model\n\n### Migrating from Sonnet 4.5 to Sonnet 4.6 (effort default change)\n\nSonnet 4.5 had no `effort` parameter; Sonnet 4.6 defaults to `high`. If you just switch the model string and do nothing else, you may see noticeably higher latency and token usage. Set `effort` explicitly.\n\n**Recommended starting points:**\n\n| Workload | Start at | Notes |\n| ------------------------------------------------- | -------------- | -------------------------------------------------------------------------------------------------------- |\n| Chat, classification, content generation | `low` | With `thinking: {\"type\": \"disabled\"}` you'll see similar or better performance vs. Sonnet 4.5 no-thinking |\n| Most applications (balanced) | `medium` | The default sweet spot for quality vs. cost |\n| Agentic coding, tool-heavy workflows | `medium` | Pair with adaptive thinking and a generous `max_tokens` (up to 128K with streaming — Sonnet 4.6's ceiling) |\n| Autonomous multi-step agents, long-horizon loops | `high` | Scale down to `medium` if latency/tokens become a concern |\n| Computer-use agents | `high` + adaptive | Sonnet 4.6's best computer-use accuracy is on adaptive + high |\n\nFor non-thinking chat workloads specifically:\n\n```python\nclient.messages.create(\n model=\"claude-sonnet-4-6\",\n max_tokens=8192,\n thinking={\"type\": \"disabled\"},\n output_config={\"effort\": \"low\"},\n messages=[{\"role\": \"user\", \"content\": \"...\"}],\n)\n```\n\n**When to use Opus 4.6 instead:** hardest and longest-horizon problems — large code migrations, deep research, extended autonomous work. Sonnet 4.6 wins on fast turnaround and cost efficiency.\n\n### Migrating to Opus 4.6 / Sonnet 4.6 (from any older model)\n\n**1. Manual extended thinking is deprecated — use adaptive thinking.**\n\n`thinking: {type: \"enabled\", budget_tokens: N}` (manual extended thinking with a fixed token budget) is deprecated on Opus 4.6 and Sonnet 4.6. Replace it with `thinking: {type: \"adaptive\"}`, which lets Claude decide when and how much to think. Adaptive thinking also enables interleaved thinking automatically (no beta header needed).\n\n```python\n# Old (still works on older models, deprecated on 4.6)\nresponse = client.messages.create(\n model=\"claude-sonnet-4-5\",\n max_tokens=16000,\n thinking={\"type\": \"enabled\", \"budget_tokens\": 8000},\n messages=[...]\n)\n\n# New (Opus 4.6 / Sonnet 4.6)\nresponse = client.messages.create(\n model=\"claude-opus-4-6\", # or \"claude-sonnet-4-6\"\n max_tokens=16000,\n thinking={\"type\": \"adaptive\"},\n output_config={\"effort\": \"high\"}, # optional: low | medium | high | max\n messages=[...]\n)\n```\n\nAdaptive thinking is the long-term target, and on internal evaluations it outperforms manual extended thinking. Move when you can.\n\n**Transitional escape hatch:** manual extended thinking is still *functional* on Opus 4.6 and Sonnet 4.6 (deprecated, will be removed in a future release). If you need a hard ceiling while migrating — for example, to bound token spend on a runaway workload before you've tuned `effort` — you can keep `budget_tokens` around alongside an explicit `effort` value, then remove it in a follow-up. `budget_tokens` must be strictly less than `max_tokens`:\n\n```python\n# Transitional only — deprecated, plan to remove\nclient.messages.create(\n model=\"claude-sonnet-4-6\",\n max_tokens=16384,\n thinking={\"type\": \"enabled\", \"budget_tokens\": 8192}, # must be < max_tokens\n output_config={\"effort\": \"medium\"},\n messages=[...],\n)\n```\n\nIf the user asks for a \"thinking budget\" on 4.6, the preferred answer is `effort` — use `low`, `medium`, `high`, or `max` rather than a token count.\n\n**2. Effort parameter (Opus 4.5, Opus 4.6, Sonnet 4.6 only).**\n\nControls thinking depth and overall token spend. Goes inside `output_config`, not top-level. Default is `high`. `max` is supported on Fable 5, Opus 4.6 and later, Sonnet 5, and Sonnet 4.6 — it errors on Sonnet 4.5 and Haiku 4.5.\n\n```python\noutput_config={\"effort\": \"medium\"} # often the best cost / quality balance\n```\n\n### Migrating to the 4.6 family (Opus 4.6 and Sonnet 4.6)\n\n**3. Assistant-turn prefills return 400 (Opus 4.6 and Sonnet 4.6).**\n\nPrefilled responses on the final assistant turn are no longer supported on either Opus 4.6 or Sonnet 4.6 — both return a 400. Adding assistant messages *elsewhere* in the conversation (e.g., for few-shot examples) still works. Pick the replacement that matches what the prefill was doing:\n\n| Prefill was used for | Replacement |\n| -------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |\n| Forcing JSON / YAML / schema output | `output_config.format` with a `json_schema` — see example below |\n| Forcing a classification label | Tool with an enum field containing valid labels, or structured outputs |\n| Skipping preambles (`Here is the summary:\\n`) | System prompt instruction: *\"Respond directly without preamble. Do not start with phrases like 'Here is...' or 'Based on...'.\"* |\n| Steering around bad refusals | Usually no longer needed — 4.6 refuses far more appropriately. Plain user-turn prompting is sufficient. |\n| Continuing an interrupted response | Move continuation into the user turn: *\"Your previous response was interrupted and ended with `[last text]`. Continue from there.\"* |\n| Injecting reminders / context hydration | Inject into the user turn instead. For complex agent harnesses, expose context via a tool call or during compaction. |\n\n```python\n# Old (fails on Opus 4.6 / Sonnet 4.6) — prefill forcing JSON shape\nmessages=[\n {\"role\": \"user\", \"content\": \"Extract the name.\"},\n {\"role\": \"assistant\", \"content\": \"{\\\"name\\\": \\\"\"},\n]\n\n# New — structured outputs replace the prefill\nresponse = client.messages.create(\n model=\"claude-opus-4-6\",\n max_tokens=1024,\n output_config={\"format\": {\"type\": \"json_schema\", \"schema\": {...}}},\n messages=[{\"role\": \"user\", \"content\": \"Extract the name.\"}],\n)\n```\n\n**4. Stream for `max_tokens > ~16K` (all models); only Haiku 4.5 caps lower, at 64K.**\n\nNon-streaming requests hit SDK HTTP timeouts at high `max_tokens`, regardless of model — stream for anything above ~16K output. The streamable ceiling is 128K for every current model except Haiku 4.5, which caps at 64K.\n\n```python\nwith client.messages.stream(model=\"claude-opus-4-6\", max_tokens=64000, ...) as stream:\n message = stream.get_final_message()\n```\n\n**5. Tool-call JSON escaping may differ (Opus 4.6 and Sonnet 4.6).**\n\nBoth 4.6 models can produce tool call `input` fields with Unicode or forward-slash escaping. Always parse with `json.loads()` / `JSON.parse()` — never raw-string-match the serialized input.\n\n### All models\n\n**6. `output_format` → `output_config.format` (API-wide).**\n\nThe old top-level `output_format` parameter on `messages.create()` is deprecated. Use `output_config.format` instead. This is not 4.6-specific — applies to every model.\n\n---\n\n## Beta Headers to Remove on 4.6\n\nSeveral beta headers that were required on 4.5 are now GA on 4.6 and should be removed. Leaving them in is harmless but misleading; removing them also lets you move from `client.beta.messages.create(...)` back to `client.messages.create(...)`.\n\n| Header | Status on 4.6 | Action |\n| ----------------------------------------- | ---------------------------------------------------------- | ------------------------------------------------------- |\n| `effort-2025-11-24` | Effort parameter is GA | Remove |\n| `fine-grained-tool-streaming-2025-05-14` | GA | Remove |\n| `interleaved-thinking-2025-05-14` | Adaptive thinking enables interleaved thinking automatically | Remove when using adaptive thinking; still functional on Sonnet 4.6 *with* manual extended thinking, but that path is deprecated |\n| `token-efficient-tools-2025-02-19` | Built in to all Claude 4+ models | Remove (no effect) |\n| `output-128k-2025-02-19` | Built in to Claude 4+ models | Remove (no effect) |\n\nOnce you remove all of these and finish moving to adaptive thinking, you can switch the SDK call site from the beta namespace back to the regular one:\n\n```python\n# Before\nresponse = client.beta.messages.create(\n model=\"claude-opus-4-5\",\n betas=[\"interleaved-thinking-2025-05-14\", \"effort-2025-11-24\"],\n ...\n)\n\n# After\nresponse = client.messages.create(\n model=\"claude-opus-4-6\",\n thinking={\"type\": \"adaptive\"},\n output_config={\"effort\": \"high\"},\n ...\n)\n```\n\n---\n\n## Additional Changes When Coming from 3.x / 4.0 / 4.1 → 4.6\n\nIf you're jumping from Opus 4.1, Sonnet 4, Sonnet 3.7, or an older Claude 3.x model directly to 4.6, apply everything above *plus* the items in this section. Users already on Opus 4.5 / Sonnet 4.5 can skip this.\n\n**1. Sampling parameters: `temperature` OR `top_p`, not both.**\n\nPassing both will error on every Claude 4+ model:\n\n```python\n# Old (3.x only — errors on 4+)\nclient.messages.create(temperature=0.7, top_p=0.9, ...)\n\n# New\nclient.messages.create(temperature=0.7, ...) # or top_p, not both\n```\n\n**2. Update tool versions.**\n\nLegacy tool versions are not supported on 4+. **Both the `type` and the `name` field change** — `text_editor_20250728` and `str_replace_based_edit_tool` are a pair; updating one without the other 400s. Also remove the `undo_edit` command from your text-editor integration:\n\n| Old | New |\n| ------------------------------------------------- | ------------------------------------------------------- |\n| `text_editor_20250124` + `str_replace_editor` | `text_editor_20250728` + `str_replace_based_edit_tool` |\n| `code_execution_*` (earlier versions) | `code_execution_20260521` |\n| `undo_edit` command | *(no longer supported — delete call sites)* |\n\n```python\n# Before\ntools = [{\"type\": \"text_editor_20250124\", \"name\": \"str_replace_editor\"}]\n\n# After — BOTH fields change\ntools = [{\"type\": \"text_editor_20250728\", \"name\": \"str_replace_based_edit_tool\"}]\n```\n\n**3. Handle the `refusal` stop reason.**\n\nClaude 4+ can return `stop_reason: \"refusal\"` on the response. If your code only handles `end_turn` / `tool_use` / `max_tokens`, add a branch:\n\n```python\nif response.stop_reason == \"refusal\":\n # Surface the refusal to the user; do not retry with the same prompt\n ...\n```\n\n**4. Handle the `model_context_window_exceeded` stop reason (4.5+).**\n\nDistinct from `max_tokens`: it means the model hit the *context window* limit, not the requested output cap. Handle both:\n\n```python\nif response.stop_reason == \"model_context_window_exceeded\":\n # Context window exhausted — compact or split the conversation\n ...\nelif response.stop_reason == \"max_tokens\":\n # Requested output cap hit — retry with higher max_tokens or stream\n ...\n```\n\n**5. Trailing newlines preserved in tool call string parameters (4.5+).**\n\n4.5 and 4.6 preserve trailing newlines that older models stripped. If your tool implementations do exact string matching against tool-call `input` values (e.g., `if name == \"foo\"`), verify they still match when the model sends `\"foo\\n\"`. Normalizing with `.rstrip()` on the receiving side is usually the simplest fix.\n\n**6. Haiku: rate limits reset between generations.**\n\nHaiku 4.5 has its own rate-limit pool separate from Haiku 3 / 3.5. If you're ramping traffic as you migrate, check your tier's Haiku 4.5 limits at [API rate limits](https://platform.claude.com/docs/en/api/rate-limits) — a quota that comfortably served Haiku 3.5 traffic may need a tier bump for the same volume on 4.5.\n\n---\n\n## Prompt-Behavior Changes (Opus 4.5 / 4.6, Sonnet 4.6)\n\nThese don't break your code, but prompts that worked on 4.5-and-earlier may over- or under-trigger on 4.6. Tune as needed.\n\n**1. Aggressive instructions cause overtriggering.** Opus 4.5 and 4.6 follow the system prompt much more closely than earlier models. Prompts written to *overcome* the old reluctance are now too aggressive:\n\n| Before (worked on 4.0 / 4.5) | After (use on 4.6) |\n| ------------------------------------------- | ----------------------------------------- |\n| `CRITICAL: You MUST use this tool when...` | `Use this tool when...` |\n| `Default to using [tool]` | `Use [tool] when it would improve X` |\n| `If in doubt, use [tool]` | *(delete — no longer needed)* |\n\nIf the model is now overtriggering a tool or skill, the fix is almost always to dial back the language, not to add more guardrails.\n\n**2. Overthinking and excessive exploration (Opus 4.6).** At higher `effort` settings, Opus 4.6 explores more before answering. If that burns too many thinking tokens, lower `effort` first (`medium` is often the sweet spot) before adding prose instructions to constrain reasoning.\n\n**3. Overeager subagent spawning (Opus 4.6).** Opus 4.6 has a strong preference for delegating to subagents. If you see it spawning a subagent for something a direct `grep` or `read` would solve, add guidance: *\"Use subagents only for parallel or independent workstreams. For single-file reads or sequential operations, work directly.\"*\n\n**4. Overengineering (Opus 4.5 / 4.6).** Both models may add extra files, abstractions, or defensive error handling beyond what was asked. If you want minimal changes, prompt for it explicitly: *\"Only make changes directly requested. Don't add helpers, abstractions, or error handling for scenarios that can't happen.\"*\n\n**5. LaTeX math output (Opus 4.6).** Opus 4.6 defaults to LaTeX (`\\frac{}{}`, `$...$`) for math and technical content. If you need plain text, instruct it explicitly: *\"Format all math as plain text — no LaTeX, no `$`, no `\\frac{}{}`. Use `/` for division and `^` for exponents.\"*\n\n**6. Skipped verbal summaries (4.6 family).** The 4.6 models are more concise and may skip the summary paragraph after a tool call, jumping straight to the next action. If you rely on those summaries for visibility, add: *\"After completing a task that involves tool use, provide a brief summary of what you did.\"*\n\n**7. \"Think\" as a trigger word (Opus 4.5 with thinking disabled).** When `thinking` is off, Opus 4.5 is particularly sensitive to the word *think* and may reason more than you want. Use `consider`, `evaluate`, or `reason through` instead.\n\n---\n\n## Model-ID Rename Quick Reference\n\n| Old string (migration source) | New string |\n| ------------------------------ | ------------------ |\n| `claude-opus-4-7` | `claude-opus-4-8` |\n| `claude-opus-4-6` | `claude-opus-4-8` |\n| `claude-opus-4-5` | `claude-opus-4-8` |\n| `claude-opus-4-1` | `claude-opus-4-8` |\n| `claude-opus-4-0` | `claude-opus-4-8` |\n| `claude-mythos-preview` | `claude-mythos-5` (Project Glasswing) or `claude-fable-5` |\n| `claude-sonnet-4-6` | `claude-sonnet-5`|\n| `claude-sonnet-4-5` | `claude-sonnet-5`|\n| `claude-sonnet-4-0` | `claude-sonnet-5`|\n\nOlder aliases (`claude-opus-4-7`, `claude-opus-4-6`, `claude-opus-4-5`, `claude-sonnet-4-6`, `claude-sonnet-4-5`, etc.) are still active and can be pinned if you need time before upgrading — see `shared/models.md` for the full legacy list.\n\n### Amazon Bedrock model IDs\n\nIf the code uses the `AnthropicBedrockMantle` client (Python `anthropic[bedrock]`, TypeScript `@anthropic-ai/bedrock-sdk`, Java `BedrockMantleBackend`, Go `bedrock.NewMantleClient`, etc.) or targets `https://bedrock-mantle.{region}.api.aws/anthropic`, it is running on **Claude in Amazon Bedrock**. All breaking changes in this guide apply unchanged there — it serves the same Messages API shape — but model IDs carry an `anthropic.` provider prefix:\n\n| First-party ID | Bedrock ID |\n|---|---|\n| `claude-opus-4-8` | `anthropic.claude-opus-4-8` |\n| `claude-opus-4-7` | `anthropic.claude-opus-4-7` |\n| `claude-sonnet-5` | `anthropic.claude-sonnet-5` |\n| `claude-haiku-4-5` | `anthropic.claude-haiku-4-5` |\n\nWhen migrating a Bedrock file, apply the same rename-table row as first-party, then keep/add the `anthropic.` prefix. Do **not** generate a first-party `claude-*` ID for a Bedrock client — it will 400.\n\n**Skip for Bedrock:** the `code_execution_*` tool-version checklist item and the **Task Budgets** section — neither is available on Bedrock (see `shared/platform-availability.md` for the per-feature table). Everything else in this guide — `effort`, adaptive/extended thinking, `output_config.format`, `thinking.display`, fine-grained tool streaming, token counting — is available on Bedrock.\n\n> **Out of scope:** the legacy Amazon Bedrock integration (`InvokeModel` / `Converse` APIs with ARN-versioned IDs like `anthropic.claude-3-5-sonnet-20241022-v2:0`) uses a different request shape and model-ID format. This guide does not cover it; WebFetch the Bedrock page in `shared/live-sources.md` if the user is migrating between the two Bedrock integrations.\n\n### Claude Platform on AWS\n\nIf the code uses `AnthropicAWS` / `AnthropicAws` / `anthropicaws.NewClient` / `AnthropicAwsClient` (or targets `https://aws-external-anthropic.{region}.api.aws`), it is running on **Claude Platform on AWS** — Anthropic-operated, same-day API parity. Model IDs are **bare first-party** strings; apply the rename table above **verbatim** and every breaking-change section in this guide unchanged. There is nothing to skip. Do **not** add an `anthropic.` prefix (that's Amazon Bedrock, a separate offering). See `shared/claude-platform-on-aws.md` for client/auth details.\n\n---\n\n## Migration Checklist\n\nEvery item is tagged: **`[BLOCKS]`** items cause a 400 error, infinite loop, silent timeout, or wrong tool selection if missed — apply these as code edits, not as suggestions. **`[TUNE]`** items are quality/cost adjustments.\n\nFor each file that calls `messages.create()` / equivalent SDK method:\n\n- [ ] **[BLOCKS]** Update the `model=` string to the new alias\n- [ ] **[BLOCKS]** Replace `budget_tokens` with `thinking={\"type\": \"adaptive\"}` (deprecated on Opus 4.6 / Sonnet 4.6)\n- [ ] **[BLOCKS]** Move `format` from top-level `output_format` into `output_config.format`\n- [ ] **[BLOCKS]** Remove any assistant-turn prefills if targeting Opus 4.6 or Sonnet 4.6 (see the prefill replacement table)\n- [ ] **[BLOCKS]** Switch to streaming if `max_tokens > ~16000` (otherwise SDK HTTP timeout)\n- [ ] **[TUNE]** Verify tool-input handling parses JSON rather than raw-string-matching the serialized input (4.6 may escape Unicode / forward slashes differently; most SDKs already expose `block.input` as a parsed object)\n- [ ] **[TUNE]** Set `output_config={\"effort\": \"...\"}` explicitly — especially when moving Sonnet 4.5 → Sonnet 4.6 (4.6 defaults to `high`)\n- [ ] **[TUNE]** Remove GA beta headers: `effort-2025-11-24`, `fine-grained-tool-streaming-2025-05-14`, `token-efficient-tools-2025-02-19`, `output-128k-2025-02-19`; remove `interleaved-thinking-2025-05-14` once on adaptive thinking\n- [ ] **[TUNE]** Switch `client.beta.messages.create(...)` → `client.messages.create(...)` once all betas are removed\n- [ ] **[TUNE]** Review system prompt for aggressive tool language (`CRITICAL:`, `MUST`, `If in doubt`) and dial it back\n\n**Extra items when coming from 3.x / 4.0 / 4.1:**\n- [ ] **[BLOCKS]** Remove either `temperature` or `top_p` (passing both 400s on Claude 4+)\n- [ ] **[BLOCKS]** Update text-editor tool `type` to `text_editor_20250728`\n- [ ] **[BLOCKS]** Update text-editor tool `name` to `str_replace_based_edit_tool` — **changing only the `type` and keeping `name: \"str_replace_editor\"` returns a 400**\n- [ ] **[BLOCKS]** Update code-execution tool to `code_execution_20260521`\n- [ ] **[BLOCKS]** Delete any `undo_edit` command call sites\n- [ ] **[TUNE]** Add handling for `stop_reason == \"refusal\"`\n- [ ] **[TUNE]** Add handling for `stop_reason == \"model_context_window_exceeded\"` (4.5+)\n- [ ] **[TUNE]** Verify tool-param string matching tolerates trailing newlines (preserved on 4.5+)\n- [ ] **[TUNE]** If moving to Haiku 4.5: review rate-limit tier (separate pool from Haiku 3.x)\n\n**Verification:**\n- [ ] Run one test request and inspect `response.stop_reason`, `response.usage`, and whether tool-use / thinking behavior matches expectations\n\nFor cached prompts: the render order and hash inputs did not change, so existing `cache_control` breakpoints keep working. However, **changing the model string invalidates the existing cache** — the first request on the new model will write the cache fresh.\n\n---\n\n## Migrating to Opus 4.7\n\n> **Model ID `claude-opus-4-7` is authoritative as written here.** When the user asks to migrate to Opus 4.7, write `model=\"claude-opus-4-7\"` exactly. Do **not** WebFetch to verify — this guide is the source of truth for migration target IDs. The corresponding entry exists in `shared/models.md`.\n\nClaude Opus 4.7 was Anthropic's most capable model at its launch and is now the previous-generation Opus (Opus 4.8 is current — see Migrating to Opus 4.8 below). It is highly autonomous and performs exceptionally well on long-horizon agentic work, knowledge work, vision tasks, and memory tasks. This section summarizes everything that was new at the 4.7 launch and remains the layered breaking-change path for callers coming from Opus 4.6 or older. It is layered on top of the 4.6 migration above — if the caller is jumping from Opus 4.5 or older, apply the 4.6 changes first, then this section, then the 4.8 section.\n\n**TL;DR for someone already on Opus 4.6:** update the model ID to `claude-opus-4-7`, strip any remaining `budget_tokens` and sampling parameters (both 400 on Opus 4.7), give `max_tokens` extra headroom and re-baseline with `count_tokens()` against the new model, opt back into `thinking.display: \"summarized\"` if reasoning is surfaced to users, and re-tune `effort` — it matters more on 4.7 than on any prior Opus.\n\n### Breaking changes (will 400 on Opus 4.7)\n\n**Extended thinking removed.**\n\n`thinking: {type: \"enabled\", budget_tokens: N}` is no longer supported on Claude Opus 4.7 or later models and returns a 400 error. Switch to adaptive thinking (`thinking: {type: \"adaptive\"}`) and use the effort parameter to control thinking depth. Adaptive thinking is **off by default** on Claude Opus 4.7: requests with no `thinking` field run without thinking, matching Opus 4.6 behavior. Set `thinking: {type: \"adaptive\"}` explicitly to enable it.\n\n```python\n# Before (Opus 4.6)\nclient.messages.create(\n model=\"claude-opus-4-6\",\n max_tokens=64000,\n thinking={\"type\": \"enabled\", \"budget_tokens\": 32000},\n messages=[{\"role\": \"user\", \"content\": \"...\"}],\n)\n\n# After (Opus 4.7)\nclient.messages.create(\n model=\"claude-opus-4-7\",\n max_tokens=64000,\n thinking={\"type\": \"adaptive\"},\n output_config={\"effort\": \"high\"}, # or \"max\", \"xhigh\", \"medium\", \"low\"\n messages=[{\"role\": \"user\", \"content\": \"...\"}],\n)\n```\n\nIf the caller wasn't using extended thinking, no change is required — thinking is off by default, or can be set explicitly with `thinking={\"type\": \"disabled\"}`.\n\nDelete `budget_tokens` plumbing entirely. For the replacement `effort` value, see **Choosing an effort level on Opus 4.7** below — there is no exact 1:1 mapping from `budget_tokens`.\n\n**Sampling parameters removed.**\n\nThe `temperature`, `top_p`, and `top_k` parameters are no longer accepted on Claude Opus 4.7. Requests that include them return a 400 error. Remove these fields from your request payloads. Prompting is the recommended way to guide model behavior on Claude Opus 4.7. If you were using `temperature = 0` for determinism, note that it never guaranteed identical outputs on prior models.\n\n```python\n# Before — errors on Opus 4.7\nclient.messages.create(temperature=0.7, top_p=0.9, ...)\n\n# After\nclient.messages.create(...) # no sampling params\n```\n\n- **If the intent was determinism** — use `effort: \"low\"` with a tighter prompt.\n- **If the intent was creative variance** — the prompt replacement depends on the use case; **ask the user** how they want variance elicited. If you can't ask, add a use-case-appropriate instruction along the lines of *\"choose something off-distribution and interesting\"* — e.g. for text generation, *\"Vary your phrasing and structure across responses\"*; for frontend/design, use the propose-4-directions approach under **Design and frontend coding** below.\n\n### Choosing an effort level on Opus 4.7\n\n`budget_tokens` controlled how much to *think*; `effort` controls how much to think *and* act, so there is no exact 1:1 mapping. **Use `xhigh` for best results in coding and agentic use cases, and a minimum of `high` for most intelligence-sensitive use cases.** Experiment with other levels to further tune token usage and intelligence:\n\n| Level | Use when | Notes |\n| --- | --- | --- |\n| `max` | Intelligence-demanding tasks worth testing at the ceiling | Can deliver gains in some use cases but may show diminishing returns from increased token usage; can be prone to overthinking |\n| `xhigh` | **Most coding and agentic use cases** | The best setting for these; used as the default in Claude Code |\n| `high` | Intelligence-sensitive use cases generally | Balances token usage and intelligence; recommended minimum for most intelligence-sensitive work |\n| `medium` | Cost-sensitive use cases that need to reduce token usage while trading off intelligence | |\n| `low` | Short, scoped tasks and latency-sensitive workloads that are not intelligence-sensitive | |\n\n### Silent default changes (no error, but behavior differs)\n\n**Thinking content omitted by default.**\n\nThinking blocks still appear in the response stream on Claude Opus 4.7, but their `thinking` field is empty unless you explicitly opt in. This is a silent change from Claude Opus 4.6, where the default was to return summarized thinking text. To restore summarized thinking content on Claude Opus 4.7, set `thinking.display` to `\"summarized\"`. **The block-field name is unchanged** — it is still `block.thinking` on a `thinking`-type block; do not rename it.\n\n**Detect this:** any code that reads `block.thinking` (or equivalent) from a `thinking`-type block and renders it in a UI, log, or trace. **The fix is the request parameter, not the response handling** — add `display: \"summarized\"` to the `thinking` parameter:\n\n```python\nthinking={\"type\": \"adaptive\", \"display\": \"summarized\"} # \"display\" is new on Opus 4.7; values: \"omitted\" (default) | \"summarized\"\n```\n\nThe default is `\"omitted\"` on Claude Opus 4.7. If thinking content was never surfaced anywhere, no change needed. If your product streams reasoning to users, the new default appears as a long pause before output begins; set `display: \"summarized\"` to restore visible progress during thinking.\n\n**Updated token counting.**\n\nClaude Opus 4.7 and Claude Opus 4.6 count tokens differently. The same input text produces a higher token count on Claude Opus 4.7 than on Claude Opus 4.6, and `/v1/messages/count_tokens` will return a different number of tokens for Claude Opus 4.7 than it did for Claude Opus 4.6. The token efficiency of Claude Opus 4.7 can vary by workload shape. Prompting interventions, `task_budget`, and `effort` can help control costs and ensure appropriate token usage. Keep in mind that these controls may trade off model intelligence. **Update your `max_tokens` parameters to give additional headroom, including compaction triggers.** Claude Opus 4.7 provides a 1M context window at standard API pricing with no long-context premium.\n\nWhat else to check:\n\n- Client-side token estimators (tiktoken-style approximations) calibrated against 4.6\n- Cost calculators that multiply tokens by a fixed per-token rate\n- Rate-limit retry thresholds keyed to measured token counts\n\nRe-baseline by re-running `client.messages.count_tokens()` against `claude-opus-4-7` on a representative sample of the caller's prompts. Do not apply a blanket multiplier. For cost-sensitive workloads, consider reducing `effort` by one level (e.g. `high` → `medium`). For agentic loops, consider adopting Task Budgets (below).\n\n### New feature: Task Budgets (beta)\n\nOpus 4.7 introduces **task budgets** — tell Claude how many tokens it has for a full agentic loop (thinking + tool calls + final output). The model sees a running countdown and uses it to prioritize work and wrap up gracefully as the budget is consumed.\n\nThis is a **suggestion the model is aware of**, not a hard cap. It is distinct from `max_tokens`, which remains the enforced per-response limit and is *not* surfaced to the model. Use `task_budget` when you want the model to self-moderate; use `max_tokens` as a hard ceiling to cap usage.\n\nRequires beta header `task-budgets-2026-03-13`:\n\n```python\nclient.beta.messages.create(\n betas=[\"task-budgets-2026-03-13\"],\n model=\"claude-opus-4-7\",\n max_tokens=64000,\n thinking={\"type\": \"adaptive\"},\n output_config={\n \"effort\": \"high\",\n \"task_budget\": {\"type\": \"tokens\", \"total\": 128000},\n },\n messages=[...],\n)\n```\n\nSet a generous budget for open-ended agentic tasks and tighten it for latency-sensitive ones. **Minimum `task_budget.total` is 20,000 tokens.** If the budget is too restrictive for the task, the model may complete it less thoroughly, referencing its budget as the constraint. **Do not add `task_budget` during a migration unless you are sure the budget value is right** — if you can run the workload and measure, do so; otherwise ask the user for the value rather than guessing. This is the primary lever for offsetting the token-counting shift on agentic workloads.\n\n### Capability improvements\n\n**High-resolution vision.** Opus 4.7 is the first Claude model with high-resolution image support. Maximum image resolution is **2576 pixels on the long edge** (up from 1568px on Opus 4.6 and prior). This unlocks gains on vision-heavy workloads, especially computer use and screenshot/artifact/document understanding. Coordinates returned by the model now map 1:1 to actual image pixels, so no scale-factor math is needed.\n\nHigh-res support is **automatic on Opus 4.7** — no beta header, no client-side opt-in required. The model accepts larger inputs and returns pixel-accurate coordinates out of the box.\n\n**Token cost.** Full-resolution images on Opus 4.7 can use up to ~3× more image tokens than on prior models (up to ~4784 tokens per image, vs. the previous ~1,600-token cap). If the extra fidelity isn't needed, downsample client-side before sending to control cost — but **do not add downsampling by default during a migration**. If you're not sure whether the pipeline needs the fidelity, ask the user rather than guessing. Use `count_tokens()` on representative images on Opus 4.7 to re-baseline before reacting to any measured cost shift.\n\nBeyond resolution, Opus 4.7 also improves on low-level perception (pointing, measuring, counting) and natural-image bounding-box localization and detection.\n\n**Knowledge work.** Meaningful gains on tasks where the model visually verifies its own output — `.docx` redlining, `.pptx` editing, and programmatic chart/figure analysis (e.g. pixel-level data transcription via image-processing libraries). If prompts have scaffolding like *\"double-check the slide layout before returning\"*, try removing it and re-baselining.\n\n**Memory.** Opus 4.7 is better at writing and using file-system-based memory. If an agent maintains a scratchpad, notes file, or structured memory store across turns, that agent should improve at jotting down notes to itself and leveraging its notes in future tasks.\n\n**User-facing progress updates.** Opus 4.7 provides more regular, higher-quality interim updates during long agentic traces. If the system prompt has scaffolding like *\"After every 3 tool calls, summarize progress\"*, try removing it to avoid excessive user-facing text. If the length or contents of Opus 4.7's updates are not well-calibrated to your use case, explicitly describe what these updates should look like in the prompt and provide examples.\n\n### Real-time cybersecurity safeguards\n\nRequests that involve prohibited or high-risk topics may lead to refusals.\n\n### Fast Mode: Opus 4.8 / 4.7 only\n\nFast mode is available on Opus 4.8 and Opus 4.7. Only surface this if the caller's code actually uses fast mode (e.g. `model=\"claude-opus-4-6-fast\"`, or `speed=\"fast\"` on an unsupported model); if the word \"fast\" does not appear in the code, say nothing about Fast Mode.\n\nWhen you see `model=\"claude-opus-4-6-fast\"` (or any retired `-fast` model string), **the migration edit is** to move the fast-mode traffic onto Opus 4.8, the durable fast-capable tier:\n\n```python\n# Request fast mode on Opus 4.8.\nclient.beta.messages.create(\n model=\"claude-opus-4-8\", max_tokens=4096,\n speed=\"fast\", betas=[\"fast-mode-2026-02-01\"],\n messages=[...],\n)\n```\n\nThat is: switch the model to Opus 4.8 and request fast mode the supported way, using the beta `client.beta.messages.…` endpoint, the `fast-mode-2026-02-01` beta flag, and `speed=\"fast\"` as a top-level request parameter (per-language form in SKILL.md § Fast Mode). Opus 4.7 also supports fast mode today, but it is itself being sunset (fast mode removed by default around Jul 25, 2026), so target Opus 4.8 as the durable choice rather than landing on a tier that is about to lose fast mode. Do **not** leave the code on a retired `-fast` model string — the failure mode differs by version: `claude-opus-4-6-fast` is already retired and the API **silently falls back** to standard Opus 4.6 (no error — the caller loses fast-mode speed without noticing); `claude-opus-4-7-fast`, once removed, will instead return an **API error** (hard failure — requests break outright rather than degrading). Either way, migrate to Opus 4.8 fast mode now.\n\n### Behavioral shifts (prompt-tunable)\n\nThese don't break anything, but prompts tuned for Opus 4.6 may land differently. Opus 4.7 is more steerable than 4.6, so small prompt nudges usually close the gap.\n\n**More literal instruction following.** Claude Opus 4.7 interprets prompts more literally and explicitly than Claude Opus 4.6, particularly at lower effort levels. It will not silently generalize an instruction from one item to another, and it will not infer requests you didn't make. The upside of this literalism is precision and less thrash. It generally performs better for API use cases with carefully tuned prompts, structured extraction, and pipelines where you want predictable behavior. A prompt and harness review may be especially helpful for migration to Claude Opus 4.7.\n\n**Verbosity calibrates to task complexity.** Opus 4.7 scales response length to how complex it judges the task to be, rather than defaulting to a fixed verbosity — shorter answers on simple lookups, much longer on open-ended analysis. If the product depends on a particular length or style, tune the prompt explicitly. To reduce verbosity:\n\n> *\"Provide concise, focused responses. Skip non-essential context, and keep examples minimal.\"*\n\nIf you see specific kinds of over-verbosity (e.g. over-explaining), add instructions targeting those. Positive examples showing the desired level of concision tend to be more effective than negative examples or instructions telling the model what not to do. Do **not** assume existing \"be concise\" instructions should be removed — test first.\n\n**Tone and writing style.** Opus 4.7 is more direct and opinionated, with less validation-forward phrasing and fewer emoji than Opus 4.6's warmer style. As with any new model, prose style on long-form writing may shift. If the product relies on a specific voice, re-evaluate style prompts against the new baseline. If a warmer or more conversational voice is wanted, specify it:\n\n> *\"Use a warm, collaborative tone. Acknowledge the user's framing before answering.\"*\n\n**`effort` matters more than on any prior Opus.** Opus 4.7 respects `effort` levels more strictly, especially at the low end. At `low` and `medium` it scopes work to what was asked rather than going above and beyond — good for latency and cost, but on moderate tasks at `low` there is some risk of under-thinking.\n\n- If shallow reasoning shows up on complex problems, raise `effort` to `high` or `xhigh` rather than prompting around it.\n- If `effort` must stay `low` for latency, add targeted guidance: *\"This task involves multi-step reasoning. Think carefully through the problem before responding.\"*\n- **At `xhigh` or `max`, set a large `max_tokens`** so the model has room to think and act across tool calls and subagents. Start at 64K and tune from there. (`xhigh` is a new effort level on Opus 4.7, between `high` and `max`.)\n\nAdaptive-thinking triggering is also steerable. If the model thinks more often than wanted — which can happen with large or complex system prompts — add: *\"Thinking adds latency and should only be used when it will meaningfully improve answer quality — typically for problems that require multi-step reasoning. When in doubt, respond directly.\"*\n\n**Uses tools less often by default.** Opus 4.7 tends to use tools less often than 4.6 and to use reasoning more. This produces better results in most cases, but for products that rely on tools (search/retrieval, function-calling, computer-use steps), it can drop tool-use rate. Two levers:\n\n- **Raise `effort`** — `high` or `xhigh` show substantially more tool usage in agentic search and coding, and are especially useful for knowledge work.\n- **Prompt for it** — be explicit in tool descriptions or the system prompt about when and how to use the tool, and encourage the model to err on the side of using it more often:\n\n> *\"When the answer depends on information not present in the conversation, you MUST call the `search` tool before answering — do not answer from prior knowledge.\"*\n\n**Fewer subagents by default.** Opus 4.7 tends to spawn fewer subagents than 4.6. This is steerable — give explicit guidance on when delegation is desirable. For a coding agent, for example:\n\n> *\"Do NOT spawn a subagent for work you can complete directly in a single response (e.g. refactoring a function you can already see). Spawn multiple subagents in the same turn when fanning out across items or reading multiple files.\"*\n\n**Design and frontend coding.** Opus 4.7 has stronger design instincts than 4.6, with a consistent default house style: warm cream/off-white backgrounds (around `#F4F1EA`), serif display type (Georgia, Fraunces, Playfair), italic word-accents, and a terracotta/amber accent. This reads well for editorial, hospitality, and portfolio briefs, but will feel off for dashboards, dev tools, fintech, healthcare, or enterprise apps — and it appears in slide decks as well as web UIs.\n\nThe default is persistent. Generic instructions (\"don't use cream,\" \"make it clean and minimal\") tend to shift the model to a different fixed palette rather than producing variety. Two approaches work reliably:\n\n1. **Specify a concrete alternative.** The model follows explicit specs precisely — give exact hex values, typefaces, and layout constraints.\n2. **Have the model propose options before building.** This breaks the default and gives the user control:\n\n > *\"Before building, propose 4 distinct visual directions tailored to this brief (each as: bg hex / accent hex / typeface — one-line rationale). Ask the user to pick one, then implement only that direction.\"*\n\nIf the caller previously relied on `temperature` for design variety, use approach (2) — it produces meaningfully different directions across runs.\n\nOpus 4.7 also requires less frontend-design prompting than previous models to avoid generic \"AI slop\" aesthetics. Where earlier models needed a lengthy anti-slop snippet, Opus 4.7 generates distinctive, creative frontends with a much shorter nudge. This snippet works well alongside the variety approaches above:\n\n> *\"NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white or dark backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character. Use unique fonts, cohesive colors and themes, and animations for effects and micro-interactions.\"*\n\n**Interactive coding products.** Opus 4.7's token usage and behavior can differ between autonomous, asynchronous coding agents with a single user turn and interactive, synchronous coding agents with multiple user turns. Specifically, it tends to use more tokens in interactive settings, primarily because it reasons more after user turns. This can improve long-horizon coherence, instruction following, and coding capabilities in long interactive coding sessions, but also comes with more token usage. To maximize both performance and token efficiency in coding products, use `effort: \"xhigh\"` or `\"high\"`, add autonomous features (like an auto mode), and reduce the number of human interactions required from users.\n\nWhen limiting required user interactions, specify the task, intent, and relevant constraints upfront in the first human turn. Well-specified, clear, and accurate task descriptions upfront help maximize autonomy and intelligence while minimizing extra token usage after user turns — because Opus 4.7 is more autonomous than prior models, this usage pattern helps to maximize performance. In contrast, ambiguous or underspecified prompts conveyed progressively over multiple user turns tend to reduce token efficiency and sometimes performance.\n\n**Code review.** Opus 4.7 is meaningfully better at finding bugs than prior models, with both higher recall and precision. However, if a code-review harness was tuned for an earlier model, it may initially show *lower* recall — this is likely a harness effect, not a capability regression. When a review prompt says \"only report high-severity issues,\" \"be conservative,\" or \"don't nitpick,\" Opus 4.7 follows that instruction more faithfully than earlier models did: it investigates just as thoroughly, identifies the bugs, and then declines to report findings it judges to be below the stated bar. Precision rises, but measured recall can fall even though underlying bug-finding has improved.\n\nRecommended prompt language:\n\n> *\"Report every issue you find, including ones you are uncertain about or consider low-severity. Do not filter for importance or confidence at this stage — a separate verification step will do that. Your goal here is coverage: it is better to surface a finding that later gets filtered out than to silently drop a bug. For each finding, include your confidence level and an estimated severity so a downstream filter can rank them.\"*\n\nThis can be used without an actual second step, but moving confidence filtering out of the finding step often helps. If the harness has a separate verification/dedup/ranking stage, tell the model explicitly that its job at the finding stage is coverage, not filtering. If single-pass self-filtering is wanted, be concrete about the bar rather than using qualitative terms like \"important\" — e.g. *\"report any bugs that could cause incorrect behavior, a test failure, or a misleading result; only omit nits like pure style or naming preferences.\"* Iterate on prompts against a subset of evals to validate recall or F1 gains.\n\n**Computer use.** Computer use works across resolutions up to the new 2576px / 3.75MP maximum. Sending images at **1080p** provides a good balance of performance and cost. For particularly cost-sensitive workloads, **720p** or **1366×768** are lower-cost options with strong performance. Test to find the ideal settings for the use case; experimenting with `effort` can also help tune behavior.\n\n---\n\n## Opus 4.7 Migration Checklist\n\nEvery item is tagged: **`[BLOCKS]`** items cause a 400 error, infinite loop, silent truncation, or empty output if missed — apply these as code edits, not as suggestions. **`[TUNE]`** items are quality/cost adjustments — surface them to the user as recommendations.\n\n`[BLOCKS]` items prefixed with **\"If…\"** or **\"At…\"** are conditional. Before working through the list, **scan the file** for the conditions: does it surface thinking text to a UI/log? Does it set `output_config.effort` to `\"x-high\"` or `\"max\"`? Is it a security workload? Is it a multi-turn agentic loop? Apply only the items whose condition matches.\n\n- [ ] **[BLOCKS]** Replace `thinking: {type: \"enabled\", budget_tokens: N}` with `thinking: {type: \"adaptive\"}` + `output_config.effort`; delete `budget_tokens` plumbing entirely\n- [ ] **[BLOCKS]** Strip `temperature`, `top_p`, `top_k` from request construction\n- [ ] **[BLOCKS]** If thinking content is surfaced to users or stored in logs: add `thinking.display: \"summarized\"` (otherwise the rendered text is empty)\n- [ ] **[BLOCKS]** At `output_config.effort` of `xhigh` or `max`: set `max_tokens` ≥ 64000 (otherwise output truncates mid-thought)\n- [ ] **[TUNE]** Give `max_tokens` and compaction triggers extra headroom; re-run `count_tokens()` against `claude-opus-4-7` on representative prompts to re-baseline (no blanket multiplier)\n- [ ] **[TUNE]** Re-baseline cost and rate-limit dashboards *before* reacting to measured shifts\n- [ ] **[TUNE]** Re-evaluate `effort` per route — use `xhigh` for coding/agentic and a minimum of `high` for most intelligence-sensitive work; it matters more on 4.7 than any prior Opus\n- [ ] **[TUNE]** Multi-turn agentic loops: adopt the API-native Task Budgets (`output_config.task_budget`, beta `task-budgets-2026-03-13`, minimum 20k tokens) — this is for capping *cumulative* spend across a loop; per-turn depth is `effort`\n- [ ] **[TUNE]** Check for ambiguous or underspecified instructions that relied on 4.6 generalizing intent, and update them to be clearer or more precise — 4.7 follows them literally\n- [ ] **[TUNE]** Tool-use workloads: add explicit when/how-to-use guidance to tool descriptions (4.7 reaches for tools less often)\n- [ ] **[TUNE]** Verbosity: test existing length instructions before changing them — 4.7 calibrates length to task complexity, so tune for the desired output rather than assuming a direction\n- [ ] **[TUNE]** Remove forced-progress-update scaffolding (*\"after every N tool calls…\"*)\n- [ ] **[TUNE]** Remove knowledge-work verification scaffolding (*\"double-check the slide layout…\"*) and re-baseline\n- [ ] **[TUNE]** Add tone instruction if a warmer / more conversational voice is needed; re-evaluate style prompts on writing-heavy routes\n- [ ] **[TUNE]** Subagent tool present: add explicit spawn / don't-spawn guidance\n- [ ] **[TUNE]** Frontend/design output: specify a concrete palette/typeface, or have the model propose 4 visual directions before building (the default cream/serif house style is persistent)\n- [ ] **[TUNE]** Interactive coding products: use `effort: \"xhigh\"` or `\"high\"`, add autonomous features (e.g. an auto mode) to reduce human interactions, and specify task/intent/constraints upfront in the first turn\n- [ ] **[TUNE]** Code-review harnesses: remove or loosen \"only report high-severity\" / \"be conservative\" filters and have the model report every finding with confidence + severity; move filtering to a downstream step (4.7 follows severity filters more literally, which can depress measured recall)\n- [ ] **[TUNE]** Vision-heavy pipelines (screenshots, charts, document understanding): leave images at native resolution up to 2576px long edge for the accuracy gain; remove any scale-factor math from coordinate handling (coords are now 1:1 with pixels). No beta header / opt-in needed — high-res is automatic on Opus 4.7.\n- [ ] **[TUNE]** Computer-use pipelines: send screenshots at 1080p for a good performance/cost balance (720p or 1366×768 for cost-sensitive workloads); experiment with `effort` to tune behavior\n- [ ] **[TUNE]** Cost-sensitive image pipelines: full-res images on 4.7 use up to ~4784 tokens vs ~1,600 on prior models (~3×). Downsampling client-side before upload avoids the increase, but **do not downsample by default** — if you're unsure whether fidelity is needed, ask the user. Re-baseline with `count_tokens()` on representative images before reacting to cost shifts.\n\n---\n\n## Migrating to Opus 4.8\n\n> **Model ID `claude-opus-4-8` is authoritative as written here.** When the user asks to migrate to Opus 4.8, write `model=\"claude-opus-4-8\"` exactly. Do **not** WebFetch to verify — this guide is the source of truth for migration target IDs. The corresponding entry exists in `shared/models.md`.\n\nClaude Opus 4.8 is our most capable Opus-tier model — highly autonomous, with state-of-the-art long-horizon agentic execution, knowledge work, and memory. It is layered on top of the Opus 4.7 migration above. If the caller is jumping from Opus 4.6 or older, apply the 4.6 and 4.7 sections first, then this one.\n\n**No new breaking changes.** Opus 4.8 keeps the same request surface as Opus 4.7. The same calls that already work on 4.7 work unchanged on 4.8 — adaptive thinking only (`thinking: {type: \"enabled\", budget_tokens: N}` still 400s; use `{type: \"adaptive\"}`), sampling parameters (`temperature`, `top_p`, `top_k`) still rejected, last-assistant-turn prefills still 400, `thinking.display` still defaults to `\"omitted\"`, and the `low`/`medium`/`high`/`xhigh`/`max` effort levels, Task Budgets (beta), and high-resolution vision all behave as on 4.7. A 4.7 → 4.8 migration is therefore **the model-ID swap plus prompt re-tuning** — there is no required code edit beyond the model string.\n\n**TL;DR for someone already on Opus 4.7:** swap the model ID to `claude-opus-4-8`. Nothing else is required to avoid an error. Then re-tune prompts for the behavioral shifts: 4.8 narrates *more* than 4.7 (add a silence-default if you want 4.7-like terseness), writes in a warmer, less hedged voice, is more deliberate and asks more often (add autonomy guidance to claw back ask-rate), and is more conservative about reaching for search, subagents, file-based memory, and custom tools (add explicit \"when to use this\" triggering). For long-horizon agentic work, give the full task specification up front in one well-specified turn and run at high effort.\n\n### No new API breaking changes (inherited from 4.7)\n\nThese all carry over from Opus 4.7 unchanged — apply them only if the caller is coming from Opus 4.6 or earlier (see the **Migrating to Opus 4.7** section above for the before/after and the SDK-specific syntax):\n\n- `thinking: {type: \"enabled\", budget_tokens: N}` → 400. Use `thinking: {type: \"adaptive\"}` + `output_config.effort`.\n- `temperature`, `top_p`, `top_k` → 400. Remove them; steer with prompting.\n- Last-assistant-turn prefills → 400. Use `output_config.format` (structured outputs) or a system-prompt instruction.\n- `thinking.display` defaults to `\"omitted\"`; set `\"summarized\"` if you surface reasoning to users.\n\nIf the caller is already on Opus 4.7 and these are clean, there is nothing to change here.\n\n### New API feature: mid-session system prompts\n\nYou can deliver trusted instructions partway through a session by placing `{\"role\": \"system\", ...}` entries directly in the `messages` array — without editing the top-level system prompt and invalidating your prompt cache. Use it for things the application learns mid-session: the user delivered async context, a mode toggled (auto-approve enabled), files changed on disk, the remaining token budget dropped.\n\n```python\nmessages=[\n {\"role\": \"user\", \"content\": [{\"type\": \"tool_result\", \"tool_use_id\": \"...\", \"content\": \"...\"}]},\n {\"role\": \"system\", \"content\": \"This project's codebase is Go. Write code in Go.\"},\n]\n```\n\nPhrase these as **context, not commands**. State the fact and let Claude act on it; avoid override-style language (\"ignore what the user said\", \"regardless of the user's request\", \"disregard the previous instruction\"). Claude is trained to protect users from instructions that appear to work against them, and that protection applies to the system role too. No beta header is required; available on Claude Opus 4.8. For cache-placement details and the older-model `<system-reminder>` fallback, see `shared/prompt-caching.md` and `shared/agent-design.md`.\n\n### Capability improvements\n\n**Long-horizon agentic execution.** Opus 4.8 is state-of-the-art at long, autonomous agentic work — complex refactors and overnight coding runs that complete without human correction. To get the most out of it, **give the full task specification up front in a single well-specified initial turn and run at high effort** (`effort: \"high\"` or `\"xhigh\"`). Its long-horizon coherence comes partly from reasoning more at each step; combined with a clear up-front goal, that more-intelligent planning often produces more efficient *and* more accurate output than prior frontier models. The \"clear goal up front\" principle maps to two product surfaces: in Claude Code, `/goal` sets direction for the run; with **Managed Agents (CMA)**, state what \"done\" looks like via an **Outcome** (`user.define_outcome` with a gradeable rubric — the harness runs an iterate → grade → revise loop), see `shared/managed-agents-outcomes.md`.\n\n**Effort is a dimension to test, not a fixed setting.** On prior models many reached for `xhigh` reflexively to maximize intelligence. Opus 4.8 has a higher intelligence ceiling, so **start at `high` as the default and iterate** rather than defaulting to `xhigh`. Sweep `medium`, `high`, and `xhigh` on your own eval set and weigh the intelligence ↔ latency ↔ cost tradeoff per route — the relationship isn't monotonic: higher effort up front often *reduces* turn count and total cost on agentic work, while for some tasks `medium` delivers equally good results in less time. Reserve `max` for extremely hard, latency-insensitive cases. The per-level effort table in the **Migrating to Opus 4.7** section above applies unchanged on 4.8.\n\n**Writing voice and clarity.** Testers consistently describe 4.8's prose as clearer, warmer, and less hedged than prior models, with fewer measurable AI vocal tics — especially at higher effort, where it approaches expert-level prose and structure. This is roughly the **opposite** direction from the 4.7 shift (4.7 was more clipped, direct, and less validation-forward). If you added style prompts to counter 4.7's terseness or to inject warmth, re-evaluate them against the new baseline before keeping them — they may now overcorrect. 4.8 is also a stronger thought partner: more thoughtful, more willing to push back, and more likely to infer the right answer from context.\n\n**Code review and debugging.** Stronger real-bug finding and clearer explanations than 4.7 — one-shot fixes where 4.7 needed more, and correctly identifying intermittent flakes rather than declaring \"fixed\" after one clean run. The 4.7 caveat still applies: if a review harness says \"only report high-severity issues\" or \"be conservative\", 4.8 follows it literally and measured recall can drop even though underlying bug-finding improved. Tell the model to report everything and filter downstream (or review a second time) — see the **Code review** guidance in the 4.7 section for the recommended prompt.\n\n### Behavioral shifts (prompt-tunable)\n\nNone of these break code, but prompts tuned for Opus 4.7 may land differently. 4.8 follows instructions well, so small, explicit nudges close the gap.\n\n**Tool triggering is surface-dependent (search & knowledge).** 4.8's tool-triggering is more surface-dependent than in prior models: with a system prompt present it is high-precision / low-recall — web search triggers slightly more often but runs fewer rounds per trigger, while knowledge-retrieval tools (Drive, project knowledge, connected files) trigger *less* often. It searches when it's confident search is needed and otherwise answers from context, which can lower research depth on tasks that need it. Recover should-search rate with an explicit search-first instruction:\n\n> ```\n> <search_first>\n> For questions where current information would change the answer (recent events, current roles or prices, version-specific behavior, or anything the user flags as time-sensitive) search before answering rather than answering from memory. For open-ended research requests, begin searching immediately; do not ask a scoping question first unless the request is genuinely ambiguous about what to research.\n> </search_first>\n> ```\n\n**Under-utilization of subagents, memory, and custom tools.** Separately from search, 4.8 is conservative about reaching for capabilities that need an explicit \"decide to use this\" step — file-based memory, subagent delegation, custom tools. It won't reach for complex or expensive capabilities unless reasonably sure they're needed. This is steerable since 4.8 follows instructions well — say *when* each capability applies, not just that it exists:\n\n> *\"Before any task longer than a few turns, check your memory file for relevant prior context and write new findings to it as you go. When a task fans out across independent items (many files to read, many tests to run, many candidates to check), delegate to subagents rather than iterating serially.\"*\n\nThe same lever works at the **tool-description** level, not just the system prompt: prescriptive descriptions that state *when* to call a tool (e.g. \"Call this when the user asks about current prices or recent events\") give meaningful lift on 4.8 over descriptions that only state what the tool does. Make the trigger condition part of each capability's own `description`.\n\n**More user-facing narration.** 4.8 narrates more than 4.7 — more text between tool calls in long tool-calling sessions, and longer, more detailed end-of-task wrap-ups by default. If you previously added scaffolding to force interim status (\"after every 3 tool calls, summarize progress\"), **remove it** — 4.8 does this on its own. If the narration is too verbose for a coding agent, an explicit silence-default makes it behave like 4.7 with no loss of quality:\n\n> *\"Default to silence between tool calls. Only write text when you find something, change direction, or hit a blocker — one sentence each. Do not narrate routine actions ('Now I'll...', 'Let me check...', 'Looking at...'). When done: one or two sentences on the outcome. Do not recap every file or test — the user has been following along.\"*\n\nFor knowledge-work deliverables (reports, analysis readouts), verbosity responds very well to instructions in user preferences or the user turn — expose a verbosity preference rather than hard-coding a length.\n\n**More deliberate — asks more often.** 4.8 is more deliberate than prior Opus models. On minor decisions it would previously just make (a variable name, a default value, which of two equivalent approaches), it tends to pause and ask, and it often closes a completed task with \"Want me to also…?\" rather than doing the obvious next step or stopping cleanly. This is preferred for high-stakes or unfamiliar codebases, but bugs users when uncalibrated. Grant autonomy on the small stuff while keeping caution where it matters (in Claude Code testing this cut ask-rate by ~12 percentage points with no increase in over-reach):\n\n> *\"For minor choices (naming, formatting, default values, which approach among equivalents), pick a reasonable option and note it rather than asking. For scope changes or destructive actions, still ask first.\"*\n\n**Verbose reasoning when thinking is disabled.** With `thinking: {type: \"disabled\"}`, 4.8 occasionally writes longer explanations of its reasoning into the visible response, which reads as verbose when the user wants a fast, quick answer. The simplest fix is to leave adaptive thinking on — set `thinking: {type: \"adaptive\"}` (the recommended setting; it adjusts how much to think per task). Note adaptive is **not** on when the field is omitted — like Opus 4.7, a request with no `thinking` field runs without thinking, so set it explicitly. If you need thinking off for latency or cost, scope it in the system prompt:\n\n> *\"Respond only with your final answer. Do not include exploratory reasoning, intermediate drafts, diffs you considered but rejected, or meta-commentary about your process.\"*\n\n### Opus 4.8 Migration Checklist\n\nEvery item is tagged: **`[BLOCKS]`** items cause a 400 error if missed; **`[TUNE]`** items are quality/cost adjustments — surface them to the user as recommendations.\n\nFor a caller **already on Opus 4.7**, only the first item is required; everything else is `[TUNE]`.

Do **not** WebFetch to verify — this guide is the source of truth for migration target IDs. The corresponding entry exists in `shared/models.md`.\n\nClaude Sonnet 5 substantially improves on Sonnet 4.6 for coding and agentic work, reaching what was previously Opus-tier quality on many tasks. Its API surface aligns with Opus 4.7/4.8: manual extended thinking is removed (adaptive or disabled only, adaptive is the default), and non-default sampling parameters are rejected. This section is layered on top of the Sonnet 4.6 migration above — if the caller is jumping from Sonnet 4.5 or older, apply the 4.6 changes first, then this one.\n\n**TL;DR for someone already on Sonnet 4.6:** swap the model ID to `claude-sonnet-5`. Replace any remaining `thinking: {type: \"enabled\", budget_tokens: N}` with `thinking: {type: \"adaptive\"}` (the transitional escape hatch is gone — it now 400s), and note that omitting `thinking` now runs adaptive (4.6 ran thinking-off). Strip non-default `temperature`/`top_p`/`top_k`. Re-run `count_tokens()` against `claude-sonnet-5` — the new tokenizer produces ~30% more tokens for the same text, so token-budgeted limits and cost baselines shift even though per-token pricing is unchanged. `effort` defaults to `high`, the same as Sonnet 4.6 — raise to `xhigh` for the hardest coding and agentic tasks (Claude Sonnet 5 supports the full `low`/`medium`/`high`/`xhigh`/`max` range), and give `max_tokens` headroom at `xhigh`/`max` (the new tokenizer means a Sonnet-4.6-tuned `max_tokens` may truncate equivalent output). Then re-tune prompts: Claude Sonnet 5 interprets instructions more literally than 4.6 — holdover style/tone directives now apply at face value; it is more agentic by default and reaches for tools and self-verification loops more readily (with thinking disabled it is less tool-eager — add an explicit nudge); it gives better in-progress updates by default (drop forced \"summarize every N tool calls\" scaffolding); and code-review harnesses with conservative-reporting instructions may see lower recall (tell it to report everything and filter downstream).\n\n### Breaking changes (will 400 on Claude Sonnet 5)\n\nThese bring the Sonnet line onto the same request surface as Opus 4.7/4.8. See the **Per-SDK Syntax Reference** above for the language-specific spelling of each.\n\n**1. Extended thinking removed — adaptive only.** `thinking: {type: \"enabled\", budget_tokens: N}` returns a 400. The transitional escape hatch that still worked on Sonnet 4.6 is gone. Use adaptive thinking with an effort hint:\n\n```python\n# Before — deprecated on Sonnet 4.6, now errors on Claude Sonnet 5\nthinking={\"type\": \"enabled\", \"budget_tokens\": 10000}\n\n# After\nthinking={\"type\": \"adaptive\"},\noutput_config={\"effort\": \"high\"}, # or \"xhigh\" for the hardest coding/agentic tasks\n```\n\nTo turn thinking off entirely, set `thinking: {type: \"disabled\"}` — but see *Adaptive vs. disabled* below before doing so.\n\n**2. Sampling parameters rejected.** Setting `temperature`, `top_p`, or `top_k` to a non-default value returns a 400; omitting the parameter, or passing its default, is still accepted. The safest migration is to omit them entirely and steer with prompting. If the caller was relying on `temperature=0` for determinism, note in the migration comment that it never guaranteed identical outputs.\n\n```python\n# Before\nclient.messages.create(model=\"claude-sonnet-4-6\", temperature=0.2, ...)\n\n# After — omit entirely\nclient.messages.create(model=\"claude-sonnet-5\", ...)\n```\n\n**3. Bedrock only: forced `tool_choice` requires `thinking: {type: \"disabled\"}`.** On Amazon Bedrock, pass `thinking: {type: \"disabled\"}` alongside `tool_choice: {type: \"tool\", name: ...}` or `tool_choice: {type: \"any\"}`. The Claude API and Vertex AI do not require this.\n\n**Not a request-shape error, but handle it: cybersecurity safeguards.** Claude Sonnet 5 is substantially more cyber-capable than Sonnet 4.6, so — like Opus 4.7/4.8 — requests touching prohibited or high-risk topics may be refused. Handle it as a content outcome (see the `refusal` stop-reason guidance in the Claude Fable 5 section if the caller needs a fallback path).\n\n**Unchanged from Sonnet 4.6:** assistant-turn prefills still return a 400 (use `output_config.format` or a system-prompt instruction); the 1M-token context window, the 128k max-output ceiling, prompt caching, batch processing, the Files API, PDF support, vision, and the full server- and client-side tool set all carry over.\n\n### Silent default change: adaptive thinking on when `thinking` is omitted\n\nOn Sonnet 4.6, a request with no `thinking` field runs **without** thinking. On Claude Sonnet 5, the same request runs with **adaptive thinking**. This is not an error — but callers who never set `thinking` will now see thinking output (and spend thinking tokens) where they didn't before. `max_tokens` is a hard limit on total output (thinking + response text), so a workload that ran thinking-off on Sonnet 4.6 by omission may now truncate. Either set `thinking: {type: \"disabled\"}` explicitly to keep the old behavior, or revisit `max_tokens` to leave room for thinking.\n\n### Silent default change: `thinking.display` defaults to `\"omitted\"`\n\n`thinking.display` defaults to `\"omitted\"` on Claude Sonnet 5 (matching Opus 4.7/4.8 and Claude Fable 5); on Sonnet 4.6 it defaulted to `\"summarized\"`. With the default, `thinking` blocks stream with empty text — to a streaming UI this looks like a long pause before output. Combined with the adaptive-on-by-default change above, a Sonnet 4.6 caller who omits `thinking` entirely now gets adaptive thinking *and* empty-text thinking blocks. If you stream reasoning to users, set `thinking: {type: \"adaptive\", display: \"summarized\"}` explicitly. `display` controls visibility only — thinking happens and is billed the same under every setting.\n\n### New tokenizer (~30% more tokens)\n\nClaude Sonnet 5 uses the same new tokenizer as Opus 4.7/4.8. The same input text produces approximately 30% more tokens than on Sonnet 4.6. No request/response shape changes and no code edits are required, but **everything measured or budgeted in tokens shifts**: `usage` fields and `count_tokens()` results for the same text are higher, the 1M context window holds less text, and a `max_tokens` limit tuned for Sonnet 4.6 may truncate equivalent output. Per-token pricing is unchanged at the $3/$15 sticker (introductory $2/$10 per MTok applies through 2026-08-31), so the cost of an equivalent request can differ. Re-run `count_tokens()` against `claude-sonnet-5` rather than reusing counts measured against earlier models, and re-baseline cost dashboards before reacting to measured shifts.\n\n### Choosing an effort level on Claude Sonnet 5\n\n`effort` defaults to `high` when not set (same as Sonnet 4.6 and Opus 4.8). Claude Sonnet 5 supports the full `low`/`medium`/`high`/`xhigh`/`max` range — the first Sonnet-tier model with `xhigh`. **Keep the `high` default for most work and raise to `xhigh` for the hardest coding and agentic tasks**:\n\n| Level | When to use on Claude Sonnet 5 |\n| -------- | ----- |\n| `max` | Tasks needing the absolute highest capability with no token constraint. Can deliver gains in some use cases but may show diminishing returns and is sometimes prone to overthinking — test before committing |\n| `xhigh` | The hardest coding and agentic use cases — the recommended setting for those |\n| `high` | The default; balances token usage and intelligence for most use cases |\n| `medium` | Cost-saving step-down from the default — comparable to Sonnet 4.6 at `high` |\n| `low` | Short, scoped tasks and latency-sensitive workloads that aren't intelligence-sensitive (chat, simple lookups) |\n\nAs a rough cross-model mapping when migrating: Claude Sonnet 5 at `medium` is comparable in intelligence to Sonnet 4.6 at `high`, and Claude Sonnet 5 at `high` is comparable to Sonnet 4.6 at `max`. When benchmarking, match by observed thinking length rather than effort name.\n\nClaude Sonnet 5 **respects effort levels strictly, especially at the low end**. At `low` and `medium` it scopes its work to what was asked rather than going above and beyond — good for latency and cost, but on moderately complex tasks at `low` there is some risk of under-thinking. If you observe shallow reasoning on complex problems, **raise effort to `high` or `xhigh` rather than prompting around it**. If you must keep effort at `low` for latency, add targeted guidance:\n\n> *\"This task involves multi-step reasoning. Think carefully through the problem before responding.\"*\n\n**Leave `max_tokens` headroom at `xhigh`/`max`.** Set a large output token budget (up to the 128k cap, unchanged from Sonnet 4.6) so the model has room for thinking and tool calls. On long tasks, adaptive thinking can use a large share of the budget; if the budget is tight you may see a response that is almost entirely thinking followed by a truncated answer and `stop_reason: \"max_tokens\"` — raise `max_tokens` or drop to `medium`. Because Claude Sonnet 5 uses the new tokenizer (~30% more tokens for the same text), `max_tokens` limits tuned for Sonnet 4.6 may truncate equivalent output.\n\n### Adaptive vs. disabled thinking\n\nLeave adaptive thinking on. Claude Sonnet 5 calibrates thinking spend to task complexity; the small added latency is usually worth the quality gain. If the caller was running Sonnet 4.6 with thinking off, **try adaptive + `effort: \"low\"` first** rather than `thinking: {type: \"disabled\"}`.\n\nThe triggering behavior for adaptive thinking is steerable. If the model emits thinking blocks more often than wanted (which can happen with large or complex system prompts), prompt it directly — and measure the effect on quality:\n\n> *\"Thinking adds latency and should only be used when it will meaningfully improve answer quality, typically for problems that require multi-step reasoning. When in doubt, respond directly.\"*\n\nConversely, if you're running hard workloads at `medium` and seeing under-thinking, the first lever is to raise effort; if you need finer control, prompt for it directly.\n\n### Capability improvements\n\n**Coding and agentic tasks.** The largest gains over Sonnet 4.6 are in coding and agentic tasks. Claude Sonnet 5 performs well out of the box on existing Sonnet 4.6 prompts.\n\n**High-resolution vision.** Claude Sonnet 5 is the first Sonnet-tier model with high-resolution image support: maximum **2576 pixels on the long edge** (up from 1568px on Sonnet 4.6). High-res images can use up to ~3× more image tokens than on Sonnet 4.6 (4784 vs 1568 tokens per image at the limit) — if the added fidelity isn't needed, downsample before sending to control token costs. No beta header or opt-in required.\n\n**Computer use.** Supports the `computer_20251124` tool version (beta header `computer-use-2025-11-24`). Capability works across resolutions up to the 2576px / 3.75MP maximum; sending screenshots at **1080p** provides a good balance of performance and cost. For particularly cost-sensitive workloads, **720p** or **1366×768** are lower-cost options with strong performance. Test to find the ideal settings for the use case; experimenting with `effort` can also help tune behavior.\n\n### Behavioral shifts (prompt-tunable)\n\nNone of these break code, but prompts tuned for Sonnet 4.6 may land differently. Claude Sonnet 5 follows instructions closely, so small explicit directives close the gap.\n\n**Response length and verbosity.** Claude Sonnet 5 calibrates response length to task complexity rather than defaulting to a fixed verbosity — usually shorter on simple lookups, longer on open-ended analysis. If a product depends on a particular verbosity, tune the prompt. To decrease verbosity:\n\n> *\"Provide concise, focused responses. Skip non-essential context, and keep examples minimal.\"*\n\nIf you see specific kinds of verbosity (e.g. over-explaining), add targeted instructions to prevent them. Positive examples showing the desired concision tend to be more effective than telling the model what not to do.\n\n**Tool use triggering.** Claude Sonnet 5 is more agentic than Sonnet 4.6 by default and will reach for tools and run self-verification loops more readily. **With thinking disabled**, the model is less likely to reach for tools or consider searching — if the harness relies on tool calls with thinking off, add an explicit nudge in the system prompt. `effort` is also a lever: `high` and `xhigh` show substantially more tool usage in agentic search and coding. For scenarios where you want more tool use, also explicitly instruct when and how to use the tools (e.g. if web-search is under-used, describe in the prompt why and how it should be called).\n\n**User-facing progress updates.** Claude Sonnet 5 provides regular, higher-quality updates to the user throughout long agentic traces by default. If the harness has scaffolding to force interim status messages (\"After every 3 tool calls, summarize progress\"), **try removing it**. If the length or content of the updates isn't well-calibrated to the use case, describe what they should look like in the prompt and provide an example.\n\n**More literal instruction following.** Claude Sonnet 5 interprets prompts literally and explicitly, particularly at lower effort levels. It does not silently generalize an instruction from one item to another, and it does not infer requests that weren't made. The upside is precision — better for carefully tuned prompts, structured extraction, and pipelines that need predictable behavior. If an instruction should apply broadly, **state the scope explicitly** (\"Apply this formatting to every section, not just the first one\"). The same literalism means style/tone directives carried over from Sonnet 4.6 may now over-apply — re-baseline holdover lines like \"be concise\" before keeping them.\n\n**Tone and writing style.** Prose style on long-form writing may shift. If a product relies on a specific voice, re-evaluate style prompts against the new baseline. For a warmer or more conversational voice:\n\n> *\"Use a warm, collaborative tone. Acknowledge the user's framing before answering.\"*\n\nBecause `temperature`/`top_p`/`top_k` are not accepted on Claude Sonnet 5, callers who previously relied on `temperature` for stylistic variety must use system-prompt instructions instead.\n\n**Code review harnesses.** A review harness tuned for an earlier model may initially see lower recall on Claude Sonnet 5. This is likely a harness effect, not a capability regression: when a review prompt says \"only report high-severity issues\" / \"be conservative\" / \"don't nitpick,\" Claude Sonnet 5 follows that instruction more faithfully than earlier models did — it investigates just as thoroughly, identifies the bugs, and then doesn't report findings it judges below the stated bar. Precision typically rises, but measured recall can fall even though underlying bug-finding ability has improved. Recommended prompt language:\n\n> *\"Report every issue you find, including ones you are uncertain about or consider low-severity. Do not filter for importance or confidence at this stage — a separate verification step will do that. Your goal here is coverage: it is better to surface a finding that later gets filtered out than to silently drop a real bug. For each finding, include your confidence level and an estimated severity so a downstream filter can rank them.\"*\n\nThis works even without an actual second step, but moving confidence filtering out of the finding stage often helps. If you do want single-pass self-filtering, be concrete about where the bar is rather than using qualitative terms like \"important\" — e.g. \"report any bugs that could cause incorrect behavior, a test failure, or a misleading result; only omit nits like pure style or naming preferences.\" Iterate against a subset of evals to validate recall/F1 gains.\n\n**Design and frontend defaults.** Claude Sonnet 5 may settle into a consistent default visual style on open-ended frontend and design briefs. Generic instructions (\"don't use that color,\" \"make it clean and minimal\") tend to shift it to a different fixed palette rather than producing variety. Two approaches work reliably: **specify a concrete alternative** (the model follows explicit specs precisely — give the palette, typography, layout, and spacing), or **have the model propose options before building** (e.g. \"Before building, propose 4 distinct visual directions tailored to this brief — bg hex / accent hex / typeface plus a one-line rationale — ask the user to pick one, then implement only that direction\"). Because `temperature` isn't accepted on Claude Sonnet 5, the propose-then-pick approach is the recommended way to get meaningfully different design directions across runs. To steer away from generic AI-aesthetic patterns, a short directive in the system prompt also helps:\n\n> *\"NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white or dark backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character. Use unique fonts, cohesive colors and themes, and animations for effects and micro-interactions.\"*\n\n**Interactive coding products.** Token usage and behavior can differ between autonomous, asynchronous coding agents (single user turn) and interactive, synchronous coding agents (multiple user turns). To maximize both performance and token efficiency, use `effort: \"xhigh\"` or `\"high\"`, add autonomous features like an auto mode, and reduce the number of human interactions required. Specify task, intent, and constraints upfront in the first turn — well-specified initial prompts maximize autonomy and intelligence while minimizing extra token usage after user turns; ambiguous or progressively-revealed prompts tend to reduce token efficiency and sometimes performance.\n\n### Claude Sonnet 5 Migration Checklist\n\nEvery item is tagged: **`[BLOCKS]`** items cause a 400 error or truncated output if missed; **`[TUNE]`** items are quality/cost adjustments — surface them to the user as recommendations.\n\n- [ ] **[BLOCKS]** Update the `model=` string to `claude-sonnet-5`\n- [ ] **[BLOCKS]** Replace `thinking: {type: \"enabled\", budget_tokens: N}` with `thinking: {type: \"adaptive\"}` + `output_config.effort` — the Sonnet 4.6 transitional escape hatch is gone\n- [ ] **[BLOCKS]** Strip `temperature`, `top_p`, `top_k` from request construction (use system-prompt instructions for tone/variety instead)\n- [ ] **[BLOCKS]** Bedrock only: pass `thinking: {type: \"disabled\"}` alongside forced `tool_choice` (`{type: \"tool\"}` / `{type: \"any\"}`) — not required on the Claude API or Vertex AI\n- [ ] **[BLOCKS]** At `effort: \"xhigh\"` or `\"max\"`: set a large `max_tokens` (up to 128k, unchanged from Sonnet 4.6) so the model has room for thinking and tool calls — Sonnet-4.6-tuned limits may truncate equivalent output under the new tokenizer (symptom: `stop_reason: \"max_tokens\"`)\n- [ ] **[TUNE]** Thinking-field omitted: adaptive is now the default (4.6 ran thinking-off) — either set `thinking: {type: \"disabled\"}` to preserve the old behavior, or revisit `max_tokens` for the added thinking spend\n- [ ] **[TUNE]** `thinking.display` defaults to `\"omitted\"` (4.6 defaulted to `\"summarized\"`): if you stream reasoning to users, set `thinking: {type: \"adaptive\", display: \"summarized\"}` explicitly — the default streams empty-text thinking blocks (long pause before output)\n- [ ] **[TUNE]** New tokenizer: re-run `count_tokens()` against `claude-sonnet-5` (~30% more tokens for the same text); revisit `max_tokens` and compaction triggers sized close to expected output length; re-baseline cost dashboards before reacting (per-token pricing unchanged)\n- [ ] **[TUNE]** Effort: keep the `high` default; raise to `xhigh` for the hardest coding/agentic tasks; `medium` is a cost-saving step-down (≈ Sonnet 4.6 at `high`); reserve `low` for short, latency-sensitive, non-intelligence-sensitive tasks. If shallow reasoning shows up at `low`/`medium`, raise effort rather than prompting around it\n- [ ] **[TUNE]** Thinking-off callers: try `thinking: {type: \"adaptive\"}` + `effort: \"low\"` instead of `disabled`; if `disabled` must stay, add an explicit tool-triggering nudge (the model is less tool-eager with thinking off)\n- [ ] **[TUNE]** Tool usage: more agentic than 4.6 by default (reaches for tools and self-verification more readily) — `effort` is a lever (`high`/`xhigh` for more tool use); add explicit when/how triggering instructions for under-used tools\n- [ ] **[TUNE]** Drop forced progress-update scaffolding (\"after every N tool calls, summarize\") — the default updates are higher quality; describe the desired update shape if it still needs tuning\n- [ ] **[TUNE]** Re-baseline holdover style/tone/scope directives — instructions are followed literally; state the scope explicitly when one should apply broadly\n- [ ] **[TUNE]** Verbosity-sensitive routes: tune response length via prompt (positive examples > \"don't\" instructions)\n- [ ] **[TUNE]** Code-review harnesses with conservative-reporting instructions (\"only high-severity\", \"don't nitpick\"): switch to a coverage-first prompt (report everything with confidence + severity) and filter downstream — measured recall can otherwise fall even though bug-finding improved\n- [ ] **[TUNE]** Open-ended frontend/design briefs: specify a concrete spec, or have the model propose 3–4 visual directions and pick one (the recommended substitute for `temperature`-driven variety)\n- [ ] **[TUNE]** Interactive coding products: use `effort: \"xhigh\"`/`\"high\"`, add autonomous features (e.g. auto mode), and put task/intent/constraints in the first turn\n- [ ] **[TUNE]** Vision-heavy / computer-use pipelines: leave images at native resolution up to 2576px long edge for the accuracy gain (downsample to control image-token cost if fidelity isn't needed); for computer use, 1080p screenshots are a good performance/cost balance with `computer_20251124`\n- [ ] **[TUNE]** Security workloads: add handling for safeguard refusals (cyber-capable topics may now be declined where Sonnet 4.6 answered)\n\n---\n\n## Migrating to Claude Fable 5\n\n> **Model IDs `claude-fable-5` and `claude-mythos-5` are authoritative as written here.** When the user asks to migrate to Claude Fable 5, write `model=\"claude-fable-5\"` exactly; a Mythos Preview migrator in Project Glasswing writes `model=\"claude-mythos-5\"` (everyone else: `claude-fable-5`). Do **not** WebFetch to verify — this guide is the source of truth for migration target IDs. The corresponding entries exist in `shared/models.md`.\n\nClaude Fable 5 is Anthropic's most capable widely released model — for the most demanding reasoning and long-horizon agentic work. **Claude Mythos 5** (`claude-mythos-5`) offers the same capabilities, pricing, and API behavior through Project Glasswing (participation is the only way to access it), and succeeds the invitation-only **Claude Mythos Preview** (`claude-mythos-preview`). Everything in this section applies to both models — only the ID differs. Mythos Preview migrators in Project Glasswing target `claude-mythos-5`; everyone else targets `claude-fable-5`. 1M token context window by default (the maximum is also the default), up to 128K output tokens per request.\n\n**Migrate to Claude Fable 5 only when the user explicitly chose it.** It is not the default Opus upgrade path — pricing is above Opus-tier. For \"upgrade to the latest model\" requests, the target remains `claude-opus-4-8`.\n\n### Breaking changes (vs Opus-tier and Mythos Preview)\n\n1. **Thinking is always on — remove all `thinking` configuration.** Adaptive thinking applies automatically whenever the `thinking` parameter is unset (an explicit `{type: \"adaptive\"}` is also accepted). Any other configuration is rejected: `thinking: {type: \"disabled\"}` and `{type: \"enabled\", budget_tokens: N}` both return a 400. `budget_tokens` has no replacement — the `output_config.effort` parameter is a separate output-level control, not a thinking budget.\n\n ```python\n # Before (Mythos Preview / older models)\n client.messages.create(\n model=\"claude-mythos-preview\",\n max_tokens=16000,\n thinking={\"type\": \"enabled\", \"budget_tokens\": 10000},\n messages=[...],\n )\n\n # After (Claude Fable 5) — no thinking field at all\n client.messages.create(\n model=\"claude-fable-5\",\n max_tokens=16000,\n output_config={\"effort\": \"high\"},\n messages=[...],\n )\n ```\n\n2. **Assistant prefill is not supported.** Replace last-assistant-turn prefills with structured outputs (`output_config.format`) or system prompt instructions — same replacement patterns as the 4.6-family prefill removal above. (One exception: the fallback-credit prefill claim — the server accepts the echoed assistant message when redeeming a credit; see the refusal section below.)\n\n3. **Interleaved scratchpad is not supported** (Mythos Preview migrators only). Inter-tool reasoning is returned in thinking blocks instead, which adaptive thinking produces automatically between tool calls.\n\n### Thinking output on Claude Fable 5 and Claude Mythos 5\n\nOn Claude Fable 5 and Claude Mythos 5, the raw chain of thought is never returned. What you receive are **regular `thinking` blocks**, not encrypted blobs or `redacted_thinking`: `display: \"summarized\"` returns a readable summary of the reasoning, and with `\"omitted\"` — the default, same as Opus 4.8/4.7 — responses still include `thinking` blocks but the `thinking` field is an empty string. `display` controls visibility only; thinking happens and is billed the same under every setting. When continuing a conversation on the same model, pass thinking blocks back to the API **unchanged** (the standard multi-turn pattern; dropping or editing them breaks the turn).\n\nWhen continuing on the same model, pass each thinking block back **exactly as received — including blocks whose `thinking` text is empty**. The API rejects blocks whose content has been *modified*, not blocks you have read; displaying the summary is fine, editing or reconstructing blocks is not.\n\nRegular thinking blocks aren't origin-locked — they replay across models fine (the server renders them into the target model's prompt). Claude Fable 5/Claude Mythos 5 thinking is the exception: a thinking block from these models replayed to a different model is **dropped from the prompt** rather than rendered — typically silently (early-access builds hard-rejected with `invalid_request_error`; that broke workflows and was reverted before launch, but the new behavior is still rolling out, so don't build logic that depends on either outcome). The drop happens before the prompt is priced, so a dropped block **lowers `usage.input_tokens`** — you aren't billed for it, and there's nothing to strip for cost. Don't strip *regular* thinking blocks either: removing them can trigger ordering/signature 400s. Two rules for replay bodies stand regardless: fallback-credit retries must echo the refused body **unchanged**, and `fallback` blocks from a mid-output fallback stay where they appeared.\n\nRelated: a request that tries to elicit the model's internal reasoning *in the response text* can be refused with `stop_details.category: \"reasoning_extraction\"` — applications needing reasoning visibility should read the summarized `thinking` blocks instead of prompting for reasoning.\n\n### Tokenizer — unchanged from Opus 4.8\n\nClaude Fable 5 uses the **same tokenizer as Claude Opus 4.8** (the tokenizer introduced with Opus 4.7). Token counts are roughly unchanged when migrating from Opus 4.7/4.8 or from `claude-mythos-preview`; per-token pricing differs.\n\n- Coming **from Opus 4.7/4.8 or `claude-mythos-preview`**: token counts are roughly unchanged. Re-baseline cost and latency on your own workloads for the per-token price difference.\n- Coming **from Opus 4.6, Sonnet, Haiku, or older**: the Opus 4.7 tokenizer tokenizes the same content to roughly 1×–1.35× as many tokens (varies by content and workload shape). Do not reuse token counts, context-window budgets, or `max_tokens` settings measured on the old model; re-baseline with `count_tokens`.\n\nTo measure the difference on your own prompts, call `count_tokens` once with your current model and once with `model: \"claude-fable-5\"`, and compare the two `input_tokens` values.\n\n### `refusal` stop reason — handle before reading content\n\nClaude Fable 5 runs safety classifiers on incoming requests, targeting research biology and most cybersecurity content (Claude Fable 5 is not intended for those domains); benign adjacent work — security tooling, life-sciences tasks — can occasionally trigger false positives, which is why the fallback patterns below matter even for legitimate workloads. (Most Claude consumer surfaces ship with built-in Opus 4.8 fallbacks; API callers configure their own.) A declined request returns a **successful HTTP 200** with `stop_reason: \"refusal\"`, plus a `stop_details` object with the policy category (values such as `\"cyber\"`, `\"bio\"`, `\"reasoning_extraction\"`, `\"frontier_llm\"`, or `null` — treat `null` as a permanent valid state; see the refusal category table in the public docs for the full set). **Branch on `stop_reason`, never on `stop_details`** — `stop_details` is informational and can be `null` even on a refusal, and `explanation` is not guaranteed present. Note that classifier blocks and ordinary model refusals (the model itself declining) both surface as `stop_reason: \"refusal\"`; `stop_details.category` tells you which class you're handling, and therefore whether retrying on a fallback model is the right response. The classifier can fire **before any output** (empty `content` array; not billed at all — no input or output tokens, no rate-limit consumption) or **mid-stream** after partial output (already-streamed output is billed at normal rates — discard the partial output rather than treating it as complete). Code that reads `response.content[0]` unconditionally will break — check `stop_reason` first:\n\n```python\nresponse = client.messages.create(model=\"claude-fable-5\", max_tokens=1024, messages=[...])\nif response.stop_reason == \"refusal\":\n # classifiers declined; content is empty (pre-output) or partial (mid-stream)\n handle_refusal()\nelse:\n print(response.content[0].text)\n```\n\n**Default to opting in.** Fallbacks are not automatic on the API — a request without them simply stops on a refusal. Migrated and new Claude Fable 5 code should ship with pattern 1 below (pattern 2 on providers without server-side support) from day one, not as a later hardening step: emit the opt-in in the code, tell the user it's there, and remove it only if they decline.\n\nThree ways to retry a refused request on another model, in order of preference:\n\n**1. Server-side `fallbacks` parameter (beta: Claude API and Claude Platform on AWS) — preferred.** One round trip, a plain client, no client-side logic. Name substitute models (the only supported fallback target at launch is `claude-opus-4-8`, expansion expected); on a policy decline the API runs the next model on the same request and returns its answer, with credit-style repricing applied automatically. A `stop_reason: \"refusal\"` on the final response means the whole chain refused.\n\n```python\nresponse = client.beta.messages.create(\n model=\"claude-fable-5\",\n max_tokens=1024,\n betas=[\"server-side-fallback-2026-06-01\"],\n fallbacks=[{\"model\": \"claude-opus-4-8\"}],\n messages=[{\"role\": \"user\", \"content\": \"Hello, Claude\"}],\n)\n\n# Switch points: one fallback block per model that ran and declined this turn\nfor block in response.content:\n if block.type == \"fallback\":\n print(f\"{block.from_.model} declined; {block.to.model} continued\")\n\n# Served-by signal: a fallback_message in usage.iterations means a fallback model\n# ran; pair it with stop_reason to confirm the fallback served the response\n# (a fallback model can also refuse). Covers sticky turns too.\nfallback_ran = any(\n entry.type == \"fallback_message\" for entry in response.usage.iterations or []\n)\nif fallback_ran and response.stop_reason != \"refusal\":\n print(f\"Served by {response.model}\")\n```\n\nKey semantics:\n\n- **Header must be exactly `server-side-fallback-2026-06-01`** — other `server-side-fallback-*` values reject the `fallbacks` param with a 400. The current header carries the *earliest* date of the series (`-2026-06-09` and `-2026-06-02` were earlier previews) — do not \"correct\" it to a newer-looking date. Rejected on the Batches API; not available on Amazon Bedrock, Vertex AI, or Microsoft Foundry (use pattern 2 there — the SDK middleware). Entries may override `max_tokens` per hop (bounding that attempt's own output independently of the top-level `max_tokens`); `thinking`, `output_config`, and `speed` overrides are rolling out (`speed` additionally requires its beta) — until your requests accept them, include only `model` and `max_tokens` in each entry. Entries must be distinct and must be in the requested model's `allowed_fallback_models` (published on `/v1/models` when the `server-side-fallback-2026-06-01` beta header is set — not yet visible under the `fallback-credit-*` header alone, and not exposed on Amazon Bedrock, Vertex AI, or Microsoft Foundry). The request *with an entry's overrides merged in* must be valid as a direct request to that entry's model.\n- **Triggers on policy declines only** — rate limits, overloads, and server errors on the requested model are returned as-is, never falling back.\n- **Reading the response:** a `fallback` content block (`{\"type\": \"fallback\", \"from\": {\"model\": ...}, \"to\": {\"model\": ...}}`) marks each switch point in `content`; the served-by signal is a `fallback_message` entry in `usage.iterations` (don't rely on the block — sticky-served turns have none). Top-level `model` names the model that produced the message.\n- **Billing:** `usage.iterations` is the per-attempt source of truth; top-level `usage` covers only the attempt that produced the returned message. Declined-before-output attempts are reported but not billed; fallback attempts bill at the fallback model's rates. Each attempt claims the rate limits of the model that ran it — if the fallback model is rate-limited or overloaded, the fallback attempt is not made and the preceding refusal is returned instead with `stop_details.recommended_model` naming a model to retry directly (the recommendation is a hint, not a guarantee, and is `null` when no recommendation is available) — size fallback-model limits for expected refusal volume.\n- **Sticky routing:** once a conversation falls back, later non-streaming requests with `fallbacks` are served directly by the fallback model for ~1 hour (best-effort; org-scoped content-hash record, not message content; not recorded for ZDR orgs). Handle the requested model being tried again at any time.\n- **Echoing fallback turns back:** after a mid-output fallback, omit `thinking`, `redacted_thinking`, and `tool_use` blocks — plus any `server_tool_use` block without its matching `server_tool_result`, and any other unrecognized model-internal block type — that appear *before* the final `fallback` block; text blocks, paired server-tool blocks, and everything after the boundary echo normally. The `fallback` block itself is an ignored audit marker (keep or drop). Streaming: the retry happens on the same stream and already-received content is never invalidated — a pre-output block is seamless (`message_start` names the fallback model; the `fallback` block arrives as an ordinary `content_block_start`, first in `content` — there is no special SSE event type; note `message_start` arrives only after the declined attempt, so time-to-first-byte includes it), and a mid-stream block keeps the partial, marks the boundary with the block, and continues — only the partial's `text` blocks are passed to the fallback model as continuation context (other block types stay in `content` but aren't part of it). Sticky routing is **not consulted on streaming requests** in the initial release, so on streams the `fallback` block check is the complete signal; non-streaming mid-output declines omit the declined partial entirely.\n\n**2. SDK client-side middleware — for providers without server-side fallbacks (Amazon Bedrock, Vertex AI, Microsoft Foundry).** Register it on the client and every `client.beta.messages` request (streaming included) retries refusals automatically, splicing the fallback model's events onto the open stream in the same wire shape as pattern 1 (a `fallback` content block at each boundary, per-hop `usage.iterations`). It is also a beta surface: the middleware sends the `fallback-credit-2026-06-01` header by default so retries are repriced via credit tokens (override with its `betas` option). `BetaFallbackState` pins follow-up turns to the model that accepted (the client-side analog of sticky routing) — reuse one state object per conversation:\n\n```python\nfrom anthropic import Anthropic, BetaFallbackState, BetaRefusalFallbackMiddleware\n\nclient = Anthropic(middleware=[BetaRefusalFallbackMiddleware([{\"model\": \"claude-opus-4-8\"}])])\nstate = BetaFallbackState() # pins follow-ups to the model that accepted\nwith state:\n response = client.beta.messages.create(model=\"claude-fable-5\", max_tokens=1024, messages=messages)\n```\n\nCreate **one state per conversation** — it is the pinning scope; sharing one across conversations pins unrelated threads together, and a conversation without a state is never pinned. Per-language naming (from the GA SDK examples — don't improvise):\n\n- **TypeScript**: `betaRefusalFallbackMiddleware([...])` in the client's `middleware` array; pass `{ fallbackState: state }` (a `BetaFallbackState`) as a request option.\n- **Go**: `option.WithMiddleware(betafallback.BetaRefusalFallbackMiddleware([]anthropic.BetaFallbackParam{{Model: ...}}))` (package `lib/betafallback`); state via `betafallback.WithBetaFallbackState(&betafallback.BetaFallbackState{})` passed as a request option. Server-side equivalents: `Fallbacks: []anthropic.BetaFallbackParam{...}` + `anthropic.AnthropicBetaServerSideFallback2026_06_01`.\n- **C#**: it's a *handler* — `new AnthropicClient { Handlers = [new BetaRefusalFallbackHandler { Fallbacks = [new(Model.ClaudeOpus4_8)] }] }` (namespace `Anthropic.Helpers`); state via `BetaFallbackState.Create()` scoped per call with `using (fallbackState.Use()) { ... }`. Server-side equivalents: `Fallbacks = [new(Model.ClaudeOpus4_8)]` + `AnthropicBeta.ServerSideFallback2026_06_01`.\n\nFor languages not listed (Java, Ruby, PHP) — or for a full runnable program in any language — each public SDK repo ships a fallbacks example under `examples/` (e.g. `examples/fallbacks.py`, `examples/refusal-fallback/`): WebFetch the repo from `shared/live-sources.md` § SDK Repositories rather than improvising the binding.\n\n**3. Hand-rolled retry + fallback credit (raw HTTP, or SDKs without the middleware).** Detect the refusal via `stop_reason` and re-send the conversation as-is on a model with broader availability such as `claude-opus-4-8` (Claude Fable 5's thinking blocks are silently ignored by other models — no stripping required); keep using the fallback model for subsequent turns. **Fallback credit** (beta: Claude API, Claude Platform on AWS, Amazon Bedrock, Vertex AI, and Microsoft Foundry) makes those retries cheaper. Prompt caches are per-model, so a plain retry pays cold cache-writes on the new model. With the `fallback-credit-2026-06-01` beta header (send it on both the original request and the retry), a refusal's `stop_details` carries `fallback_credit_token` (opaque; `null` when unavailable) and `fallback_has_prefill_claim`. Echo the token as the top-level `fallback_credit_token` request parameter on the retry (typed in the GA SDKs; on a pre-GA SDK pass it via `extra_body`) and the previously-cached span bills at cache-read rates — the retry costs what it would have if the conversation had been on that model all along. Rules: the retry body must match the refused request **exactly** in every prompt-shaping field (`system`, `messages`, `tools`, `tool_choice`, `thinking` — do **not** strip thinking blocks when redeeming a credit — the server handles them); the retry model must be in the refused model's `allowed_fallback_models`; the token expires in 5 minutes; Batches results carry no tokens. If `fallback_has_prefill_claim` is `true`, append one assistant message echoing the refused response's `content` — the retry model continues from where the refused model stopped (and completed server-tool work isn't re-run). When echoing, strip trailing whitespace from a final `text` block (the prefill validator rejects it; the credit match tolerates that edit), after omitting any unpaired `tool_use` blocks. On a 400, fall back to the unchanged body with the token; on a 400 naming `fallback_credit_token`, retry without it (credit forfeited).\n\n**Migrating code built on the v1 preview.** If the code you're editing carries any of these markers, it targets the discontinued early-access surface — migrate it to the v2 shapes above, and ship the header and parameter changes together (the v1 parameter shape under the v2 header is a 400):\n\n| v1 marker (replace) | v2 |\n|---|---|\n| `server-side-fallback-2026-06-09` / `-2026-06-02` header | `server-side-fallback-2026-06-01` |\n| `fallback: {model, on_partial}` single object | `fallbacks: [{model, ...}]` array (1–3); `on_partial` no longer exists — partial-output behavior is fixed (streams keep the partial; non-streaming omits it). Unknown keys in an entry are a 400 |\n| Top-level `response.fallback` object (`from_model`, `reason`) | Never emitted — read `fallback` content blocks (switch points, no `reason` field) and `usage.iterations` (served-by) |\n| `event: fallback` SSE with discard indices | No dedicated event; streamed content is never invalidated — the switch arrives as an ordinary `content_block_start`/`stop` pair of type `fallback` |\n| `fallback_primary` / `fallback_retry` iteration types | Blocked attempts are plain `message` entries; the serving attempt is `fallback_message` |\n| `reason: \"sticky\"` | No reason field — sticky turns carry no block; detect via `fallback_message` in `usage.iterations` + `response.model` |\n| `recommended_model` meaning \"primary served the refusal\" | Now populated only when the fallback attempt *couldn't run* (rate-limited/overloaded) — its presence means a direct retry on that model may succeed, not that it refused too |\n\n### Data retention requirement\n\nClaude Fable 5 requires **30-day data retention** and is not available under zero data retention. Requests from an organization whose data-retention configuration doesn't meet the requirement return `400 invalid_request_error` — if a migration suddenly 400s with no obvious request problem, check the org's retention configuration before debugging the payload. On Amazon Bedrock, Google Vertex AI, and Microsoft Foundry, data-retention requirements are set by each platform.\n\n### What carries over unchanged\n\nSame Messages API and tool-use patterns as Opus-tier and Mythos Preview. Supported at launch: `output_config.effort` (`low`/`medium`/`high`/`xhigh`/`max`), Task Budgets (beta, `task-budgets-2026-03-13` header), compaction (beta, `compact-2026-01-12` header), the memory tool, tool-call clearing via context editing, and high-resolution vision (no downscaling cap, as on Opus 4.7+).\n\n### Behavioral shifts (prompt-tunable)\n\nNone of these are API-breaking, but they're where migrated workloads feel different. Claude Fable 5's biggest gains are on work *above* what prior models could do (long-horizon autonomous runs, first-shot implementations of well-specified systems, end-to-end enterprise deliverables — financial analysis, spreadsheets, slides, docs — code review/debugging and repository-history search, vision on dense or degraded images — it's explicitly trained to use bash and crop tools on flipped/blurry/noisy inputs — navigating ambiguity, parallel sub-agent delegation and collaboration — it reliably sustains ongoing communications with long-running sub-agents and peer agents; note bug-finding gains exclude security-focused analysis, where the cyber classifiers apply) — don't evaluate it only on workloads older models already handled.\n\n**Longer turns by default — the biggest structural shift.** Individual requests on hard tasks can run many minutes at higher effort (a 15-minute single request is normal when the task involves gathering context, building, and self-verifying). Before migrating, plan timeouts, streaming, and user-facing progress indicators; structure work so callers check in on runs asynchronously rather than blocking inside one request. On ambiguous tasks Claude Fable 5 may need a small nudge to avoid overplanning:\n\n> When you have enough information to act, act. Do not re-derive facts already established in the conversation, re-litigate a decision the user has already made, or narrate options you will not pursue in user-facing messages. If you are weighing a choice, give a recommendation, not an exhaustive survey. This does not apply to thinking blocks.\n\n**Consider all effort levels.** `output_config.effort` is the primary intelligence/latency/cost control. Recommended defaults: `high` for most tasks, `xhigh` for the most capability-sensitive workloads, `medium`/`low` for routine work. Lower effort settings — including `low` — still perform very well on Claude Fable 5, often exceeding the `xhigh` or even `max` performance of previous models. Reduce effort if a task completes correctly but takes longer than necessary, or for a quicker interactive working style. At higher effort on routine work, Claude Fable 5 can gather context and deliberate beyond what the task needs (the flip side: higher effort buys excellent verification behavior and the most rigorous outputs). To prevent unrequested tidying or refactoring at higher effort:\n\n> Don't add features, refactor, or introduce abstractions beyond what the task requires. A bug fix doesn't need surrounding cleanup and a one-shot operation usually doesn't need a helper. Don't design for hypothetical future requirements - do the simplest thing that works well. Avoid premature abstraction. Avoid half-finished implementations either. Don't add error handling, fallbacks, or validation for scenarios that cannot happen. Trust internal code and framework guarantees. Only validate at system boundaries (user input, external APIs). Don't use feature flags or backwards-compatibility shims when you can just change the code.\n\n**Instruction following is strong — use it.** Claude Fable 5 is very responsive to explicit communication-style sections in system prompts; invest in them rather than fighting output style downstream. Un-steered — especially at higher effort — it can elaborate beyond what the task needs: heavily-structured PR descriptions, sections on alternatives that weren't chosen, comments narrating what the next line does. You don't need to enumerate these behaviors by name; a brief instruction is just as effective:\n\n> Lead with the outcome. Your first sentence after finishing should answer \"what happened\" or \"what did you find\" — the thing the user would ask for if they said \"just give me the TLDR.\" Supporting detail and reasoning come after. Being readable and being concise are different things, and readability matters more. The way to keep output short is to be selective about what you include (drop details that don't change what the reader would do next), not to compress the writing into fragments, abbreviations, arrow chains like A → B → fails, or jargon.\n\n**Ground progress claims on long runs.** Require progress claims to be audited against tool results — in testing this nearly eliminated fabricated status reports on tasks designed to elicit them:\n\n> Before reporting progress, audit each claim against a tool result from this session. Only report work you can point to evidence for; if something is not yet verified, say so explicitly. Report outcomes faithfully: if tests fail, say so with the output; if a step was skipped, say that; when something is done and verified, state it plainly without hedging.\n\n**State boundaries explicitly.** Claude Fable 5 sometimes takes unrequested-but-adjacent actions (e.g. composing an email straight to drafts, creating backup git branches). Define what it should *not* do:\n\n> When the user is describing a problem, asking a question, or thinking out loud rather than requesting a change, the deliverable is your assessment. Report your findings and stop. Don't apply a fix until they ask for one. Before running a command that changes system state — restarts, deletes, config edits — check that the evidence actually supports that specific action. A signal that pattern-matches to a known failure may have a different cause.\n\n**Let it delegate — asynchronously.** Parallel sub-agents are dependable on Claude Fable 5 — instead of suppressing delegation (a common prior-model guardrail), use sub-agents frequently and give explicit guidance on *when* delegation is desirable. Sub-agents that communicate **asynchronously** with the orchestrator outperform spawn-and-block: long-lived agents keep their context instead of re-establishing it per subtask (cache-read savings), the orchestrator isn't bottlenecked on the slowest sub-agent, and context persists across subtasks.\n\n> Delegate independent subtasks to sub-agents and keep working while they run. Intervene if a sub-agent goes off track or is missing relevant context.\n\n**Give it a memory surface.** Claude Fable 5 performs notably better when it can write learnings somewhere for future reference — even a plain `.md` file. Tell it where, tell it to consult that file in future sessions, and give it a format:\n\n> Store one lesson per file with a one-line summary at the top. Record corrections and confirmed approaches alike, including why they mattered. Don't save what the repo or chat history already records; update an existing note rather than creating a duplicate; delete notes that turn out to be wrong.\n\n**Rare: early stopping.** Deep into long sessions it can occasionally end a turn with a text-only statement of intent (\"I'll now run X\") without the tool call, or ask permission it doesn't need. A \"continue\" recovers it interactively; for autonomous pipelines add a system reminder:\n\n> You are operating autonomously. The user is not watching in real time and cannot answer questions mid-task, so asking 'Want me to…?' or 'Shall I…?' will block the work. For reversible actions that follow from the original request, proceed without asking. Offering follow-ups after the task is done is fine; asking permission after already discussing with the user before doing the work is not. Before ending your turn, check your last paragraph. If it is a plan, an analysis, a question, a list of next steps, or a promise about work you have not done ('I'll…', 'let me know when…'), do that work now with tool calls. End your turn only when the task is complete or you are blocked on input only the user can provide.\n\n**Rare: context anxiety.** In very long sessions it can worry about running out of context — suggesting a new session or trimming its own work — most often when the harness surfaces a remaining-token countdown. Avoid showing explicit context-budget counts; if you must:\n\n> You have ample context remaining. Do not stop, summarize, or suggest a new session on account of context limits – continue the work.\n\n**Give the reason, not just the request.** Claude Fable 5 performs better when it understands the intent behind a request — it connects the task to relevant information rather than inferring intent on its own. This matters most for long-running agents juggling context from disparate workstreams:\n\n> I'm working on [the larger task] for [who it's for]. They need [what the output enables]. With that in mind: [request].\n\n**Readability in long agentic sessions.** Deep into extended conversations (many tool calls, large working context) Claude Fable 5 can produce text users find hard to follow — dense arrow-chain shorthand, implementation-level detail, references to thinking the user never saw. A communication-style addendum strongly mitigates this; adapt:\n\n> Terse shorthand is fine between tool calls (that's you thinking out loud, and brevity there is good). Your final summary is different: it's for a reader who didn't see any of that. If you've been working for a while without the user watching - overnight, across many tool calls, since they last spoke - your final message is their first look at any of it. Write it as a re-grounding, not a continuation of your working thread: the outcome first, then the one or two things you need from them, each explained as if new. The vocabulary you built up while working is yours, not theirs; leave it behind unless you re-introduce it. When you write the summary at the end, drop the working shorthand. Write complete sentences. Spell out terms instead of abbreviating them. Don't use arrow chains, hyphen-stacked compounds, or labels you made up earlier — the reader doesn't have the context to decode them. When you mention files, commits, flags, or other identifiers, give each one its own plain-language clause saying what it is or what changed — never pack several into one parenthesized run or slash-separated list. Open with the outcome: one sentence on what happened or what you found. Then the supporting detail. If you have to choose between short and clear, choose clear.\n\n### Long-running agent recommendations\n\n- **Make self-verification explicit.** For long-running builds, instruct it to establish and run its own checking harness on a cadence (\"Establish a method for checking your own work as you build; run it every [interval], verifying against the specification with sub-agents\"). Separate fresh-context verifier sub-agents tend to outperform self-critique.\n- **De-prescribe migrated prompts and skills.** Prompts and skills written for prior models are often too prescriptive for Claude Fable 5 and *reduce* output quality. After migrating, A/B the workload with older step-by-step scaffolding removed — prefer stating the goal and constraints over enumerating the steps. Claude Fable 5 is also good at updating skills on the fly from what it learns mid-task — let it.\n- **Start at the top of your difficulty range.** The teams with the best early-access outcomes gave it their hardest unsolved problems first — have it scope the problem, ask questions, then execute.\n- **Add a `send_to_user` tool for verbatim mid-task delivery.** When an asynchronous agent must deliver something the user sees *exactly as written* mid-run (a deliverable, a progress update with specific numbers, a direct answer), give it a client-side tool whose input you render directly in the UI — tool inputs are never summarized, so content arrives intact. Return a simple acknowledgement as the tool result:\n\n```json\n{\n \"name\": \"send_to_user\",\n \"description\": \"Display a message directly to the user. Use this for progress updates, partial results, or content the user must see exactly as written before the task finishes.\",\n \"input_schema\": {\n \"type\": \"object\",\n \"properties\": {\n \"message\": { \"type\": \"string\", \"description\": \"The content to display to the user.\" }\n },\n \"required\": [\"message\"]\n }\n}\n```\n\nFor agents that only narrate routine progress, the model's default progress narration is typically adequate without this tool.\n\n### Claude Fable 5 Migration Checklist\n\n- [ ] **[BLOCKS]** Update the `model=` string to `claude-fable-5` (`claude-mythos-5` for Mythos Preview migrators in Project Glasswing)\n- [ ] **[BLOCKS]** Remove `thinking: {type: \"disabled\"}` (errors on Claude Fable 5)\n- [ ] **[BLOCKS]** Replace assistant prefill with structured outputs or system prompt instructions\n- [ ] **[BLOCKS]** Confirm the org meets the 30-day data-retention requirement (ZDR orgs get `400 invalid_request_error` on every request)\n- [ ] **[BLOCKS]** Remove all other `thinking` configuration (`{type: \"enabled\", budget_tokens: N}` returns a 400, same as on Opus 4.7/4.8); control depth with `output_config.effort` instead\n- [ ] **[BLOCKS]** If thinking content is surfaced to users or stored in logs: add `thinking: {type: \"adaptive\", display: \"summarized\"}` (the default is `\"omitted\"` — otherwise the rendered text is empty)\n- [ ] **[TUNE]** Re-baseline cost and latency on your own workloads — token counts are roughly unchanged from Opus 4.7/4.8 and Mythos Preview (same tokenizer); per-token pricing differs. Coming from Opus 4.6, Sonnet, Haiku, or older, token counts differ — use `count_tokens` with each model to compare\n- [ ] **[TUNE]** Add `stop_reason == \"refusal\"` handling before reading `response.content` (pre-output: empty + unbilled; mid-stream: partial output billed — discard); opt into a fallback by default — server-side `fallbacks` (`server-side-fallback-2026-06-01`, Claude API and Claude Platform on AWS) where available, otherwise the SDK middleware or fallback credit (`fallback-credit-2026-06-01`, exact body); a bare client-side replay (history as-is; other models drop Fable's thinking blocks) is the floor, not the recommendation\n- [ ] **[TUNE]** If you surfaced thinking text to users, plan for the thinking output change — the raw chain of thought is never returned; render the `display: \"summarized\"` summary (per the [BLOCKS] item above); pass blocks back unchanged on the same model; other models drop them from the prompt (unbilled)\n- [ ] **[TUNE]** Plan for minutes-long turns: timeouts, streaming, async check-ins, progress UX (see Behavior changes above)\n- [ ] **[TUNE]** Run an effort sweep including low/medium for routine workloads; add the no-tidying instruction if higher effort produces unrequested refactors\n- [ ] **[TUNE]** A/B with prior-model scaffolding removed — over-prescriptive prompts/skills reduce Claude Fable 5 output quality\n\n---\n\n## Verify the Migration\n\nAfter updating, spot-check that the new model is actually being used. Replace `YOUR_TARGET_MODEL` with the model string you migrated to (e.g. `claude-fable-5`, `claude-opus-4-8`, `claude-opus-4-7`, `claude-sonnet-5`, `claude-sonnet-4-6`, `claude-haiku-4-5`) and keep the assertion prefix in sync:\n\n```python\nYOUR_TARGET_MODEL = \"claude-opus-4-8\" # or \"claude-opus-4-7\", \"claude-sonnet-5\", \"claude-sonnet-4-6\", \"claude-haiku-4-5\"\nresponse = client.messages.create(model=YOUR_TARGET_MODEL, max_tokens=64, messages=[...])\nassert response.model.startswith(YOUR_TARGET_MODEL), response.model\n```\n\nFor rate-limit headroom changes, pricing, or capability deltas (vision, structured outputs, effort support), query the Models API:\n\n```python\nm = client.models.retrieve(YOUR_TARGET_MODEL)\nm.max_input_tokens, m.max_tokens\nm.capabilities[\"effort\"][\"max\"][\"supported\"]\n```\n\nSee `shared/models.md` for the full capability lookup pattern.\n</doc>\n\n<doc path=\"shared/models.md\">\n# Claude Model Catalog\n\n**Only use exact model IDs listed in this file.** Never guess or construct model IDs — incorrect IDs will cause API errors. Use aliases wherever available. For the latest information, WebFetch the Models Overview URL in `shared/live-sources.md`, or query the Models API directly (see Programmatic Model Discovery below).\n\n## Programmatic Model Discovery\n\nFor **live** capability data — context window, max output tokens, feature support (thinking, vision, effort, structured outputs, etc.) — query the Models API instead of relying on the cached tables below. Use this when the user asks \"what's the context window for X\", \"does model X support vision/thinking/effort\", \"which models support feature Y\", or wants to select a model by capability at runtime.\n\n```python\nm = client.models.retrieve(\"claude-opus-4-8\")\nm.id # \"claude-opus-4-8\"\nm.display_name # \"Claude Opus 4.8\"\nm.max_input_tokens # context window (int)\nm.max_tokens # max output tokens (int)\n\n# capabilities is an untyped nested dict — bracket access, check [\"supported\"] at the leaf\ncaps = m.capabilities\ncaps[\"image_input\"][\"supported\"] # vision\ncaps[\"thinking\"][\"types\"][\"adaptive\"][\"supported\"] # adaptive thinking\ncaps[\"effort\"][\"max\"][\"supported\"] # effort: max (also low/medium/high)\ncaps[\"structured_outputs\"][\"supported\"]\ncaps[\"context_management\"][\"compact_20260112\"][\"supported\"]\n\n# filter across all models — iterate the page object directly (auto-paginates); do NOT use .data\n[m for m in client.models.list()\n if m.capabilities[\"thinking\"][\"types\"][\"adaptive\"][\"supported\"]\n and m.max_input_tokens >= 200_000]\n```\n\nTop-level fields (`id`, `display_name`, `max_input_tokens`, `max_tokens`) are typed attributes. `capabilities` is a dict — use bracket access, not attribute access. The API returns the full capability tree for every model with `supported: true/false` at each leaf, so bracket chains are safe without `.get()` guards. TypeScript SDK: same method names, also auto-paginates on iteration.\n\n### Raw HTTP\n\n```bash\ncurl https://api.anthropic.com/v1/models/claude-opus-4-8 \\\n -H \"x-api-key: $ANTHROPIC_API_KEY\" \\\n -H \"anthropic-version: 2023-06-01\"\n```\n\n```json\n{\n \"id\": \"claude-opus-4-8\",\n \"display_name\": \"Claude Opus 4.8\",\n \"max_input_tokens\": 1000000,\n \"max_tokens\": 128000,\n \"capabilities\": {\n \"image_input\": {\"supported\": true},\n \"structured_outputs\": {\"supported\": true},\n \"thinking\": {\"supported\": true, \"types\": {\"enabled\": {\"supported\": false}, \"adaptive\": {\"supported\": true}}},\n \"effort\": {\"supported\": true, \"low\": {\"supported\": true}, …, \"max\": {\"supported\": true}},\n …\n }\n}\n```\n\n## Current Models (recommended)\n\n| Friendly Name | Alias (use this) | Full ID | Context | Max Output | Status |\n|-------------------|---------------------|-------------------------------|----------------|------------|--------|\n| Claude Fable 5 | `claude-fable-5` | — | 1M | 128K | Active |\n| Claude Mythos 5 | `claude-mythos-5` | — | 1M | 128K | Active (Project Glasswing only) |\n| Claude Opus 4.8 | `claude-opus-4-8` | — | 1M | 128K | Active |\n| Claude Opus 4.7 | `claude-opus-4-7` | — | 1M | 128K | Active |\n| Claude Opus 4.6 | `claude-opus-4-6` | — | 1M | 128K | Active |\n| Claude Sonnet 5 | `claude-sonnet-5` | — | 1M | 128K | Active |\n| Claude Sonnet 4.6 | `claude-sonnet-4-6` | - | 1M | 128K | Active |\n| Claude Haiku 4.5 | `claude-haiku-4-5` | `claude-haiku-4-5-20251001` | 200K | 64K | Active |\n\n### Model Descriptions\n- **Claude Fable 5** — Anthropic's most capable widely released model, for the most demanding reasoning and long-horizon agentic work. Same API surface as Opus 4.7/4.8 with one new breaking change: an explicit `thinking: {type: \"disabled\"}` returns a 400 — omit the `thinking` parameter instead (thinking is always on; the raw chain of thought is never returned — summaries via `display: \"summarized\"`). Same tokenizer as Opus 4.8 (token counts roughly unchanged vs Opus 4.7/4.8). Safety classifiers may return `stop_reason: \"refusal\"`. No assistant prefill. Requires 30-day data retention (not available under ZDR). $10/$50 per MTok; 1M context window (default), 128K max output. See `shared/model-migration.md` → Migrating to Claude Fable 5.\n- **Claude Mythos 5** — Same capabilities, pricing, limits, and API behavior as Claude Fable 5; only the model ID differs. Available exclusively through Project Glasswing, where it joins (and succeeds) the invitation-only Claude Mythos Preview (`claude-mythos-preview`). Use it only when the org participates in Project Glasswing; otherwise use claude-fable-5.\n- **Claude Opus 4.8** — The most capable Opus-tier model — highly autonomous, state-of-the-art on long-horizon agentic work, knowledge work, and memory; clearer, warmer writing. Same API surface as Opus 4.7 (adaptive thinking only; sampling parameters and `budget_tokens` removed). 1M context window at standard API pricing (no long-context premium). See `shared/model-migration.md` → Migrating to Opus 4.8 — a 4.7 → 4.8 move is a model-ID swap plus prompt re-tuning, no new breaking changes.\n- **Claude Opus 4.7** — Previous-generation Opus. Highly autonomous; strong on long-horizon agentic work, knowledge work, vision, and memory. Adaptive thinking only; sampling parameters and `budget_tokens` removed. 1M context window. See `shared/model-migration.md` → Migrating to Opus 4.7.\n- **Claude Opus 4.6** — Older Opus. Supports adaptive thinking (recommended), 128K max output tokens (requires streaming for large outputs). 1M context window.\n- **Claude Sonnet 5** — The best combination of speed and intelligence in the Sonnet tier; near-Opus quality on coding and agentic work. Adaptive thinking on by default (omitting `thinking` runs adaptive); manual `budget_tokens` removed; non-default sampling parameters rejected. `effort` supports `low`/`medium`/`high`/`xhigh`/`max`. New tokenizer (~30% more tokens for the same text vs Sonnet 4.6). High-resolution vision (2576px). 1M context window, 128K max output. See `shared/model-migration.md` → Migrating to Claude Sonnet 5.\n- **Claude Sonnet 4.6** — Previous-generation Sonnet. Supports adaptive thinking (recommended). 1M context window. 128K max output tokens.\n- **Claude Haiku 4.5** — Fastest and most cost-effective model for simple tasks.\n\n## Legacy Models (still active)\n\n| Friendly Name | Alias (use this) | Full ID | Status |\n|-------------------|---------------------|-------------------------------|--------|\n| Claude Opus 4.5 | `claude-opus-4-5` | `claude-opus-4-5-20251101` | Active |\n| Claude Opus 4.1 | `claude-opus-4-1` | `claude-opus-4-1-20250805` | Deprecated (retires 2026-08-05 — migrate to `claude-opus-4-8`) |\n| Claude Sonnet 4.5 | `claude-sonnet-4-5` | `claude-sonnet-4-5-20250929` | Active |\n\n## Deprecated Models (retiring soon)\n\n| Friendly Name | Alias (use this) | Full ID | Status | Retires |\n|-------------------|---------------------|-------------------------------|------------|--------------|\n| Claude Sonnet 4 | `claude-sonnet-4-0` | `claude-sonnet-4-20250514` | Deprecated | TBD |\n| Claude Opus 4 | `claude-opus-4-0` | `claude-opus-4-20250514` | Deprecated | TBD |\n| Claude Haiku 3 | — | `claude-3-haiku-20240307` | Deprecated | Apr 19, 2026 |\n\n## Retired Models (no longer available)\n\n| Friendly Name | Full ID | Retired |\n|-------------------|-------------------------------|-------------|\n| Claude Sonnet 3.7 | `claude-3-7-sonnet-20250219` | Feb 19, 2026 |\n| Claude Haiku 3.5 | `claude-3-5-haiku-20241022` | Feb 19, 2026 |\n| Claude Opus 3 | `claude-3-opus-20240229` | Jan 5, 2026 |\n| Claude Sonnet 3.5 | `claude-3-5-sonnet-20241022` | Oct 28, 2025 |\n| Claude Sonnet 3.5 | `claude-3-5-sonnet-20240620` | Oct 28, 2025 |\n| Claude Sonnet 3 | `claude-3-sonnet-20240229` | Jul 21, 2025 |\n| Claude 2.1 | `claude-2.1` | Jul 21, 2025 |\n| Claude 2.0 | `claude-2.0` | Jul 21, 2025 |\n\n## Resolving User Requests\n\nWhen a user asks for a model by name, use this table to find the correct model ID:\n\n| User says... | Use this model ID |\n|-------------------------------------------|--------------------------------|\n| \"fable\", \"most capable model\" | `claude-fable-5` |\n| \"most powerful\" | `claude-fable-5` |\n| \"mythos\", \"mythos 5\" | `claude-mythos-5` (Project Glasswing participants only; otherwise use `claude-fable-5`) |\n| \"mythos preview\" | `claude-mythos-5` (successor to `claude-mythos-preview` — see migration guide) |\n| \"opus\" | `claude-opus-4-8` |\n| \"opus 4.8\" | `claude-opus-4-8` |\n| \"opus 4.7\" | `claude-opus-4-7` |\n| \"opus 4.6\" | `claude-opus-4-6` |\n| \"opus 4.5\" | `claude-opus-4-5` |\n| \"opus 4.1\" | `claude-opus-4-1` (deprecated, retires 2026-08-05 — suggest `claude-opus-4-8`) |\n| \"opus 4\", \"opus 4.0\" | `claude-opus-4-0` (deprecated — suggest `claude-opus-4-8`) |\n| \"sonnet\", \"balanced\" | `claude-sonnet-5` |\n| \"sonnet 5\" | `claude-sonnet-5` |\n| \"sonnet 4.6\" | `claude-sonnet-4-6` |\n| \"sonnet 4.5\" | `claude-sonnet-4-5` |\n| \"sonnet 4\", \"sonnet 4.0\" | `claude-sonnet-4-0` (deprecated — suggest `claude-sonnet-5`) |\n| \"sonnet 3.7\" | Retired — suggest `claude-sonnet-5` |\n| \"sonnet 3.5\" | Retired — suggest `claude-sonnet-5` |\n| \"haiku\", \"fast\", \"cheap\" | `claude-haiku-4-5` |\n| \"haiku 4.5\" | `claude-haiku-4-5` |\n| \"haiku 3.5\" | Retired — suggest `claude-haiku-4-5` |\n| \"haiku 3\" | Deprecated — suggest `claude-haiku-4-5` |\n</doc>\n\n<doc path=\"shared/platform-availability.md\">\n# Platform Availability\n\nWhich features work on which provider platform. **This table is the single source of truth in this skill** — per-feature sections elsewhere point here instead of restating availability.

For language-specific syntax, see the `## Prompt Caching` section in each language's README or single-file doc.\n\n## The one invariant everything follows from\n\n**Prompt caching is a prefix match. Any change anywhere in the prefix invalidates everything after it.**\n\nThe cache key is derived from the exact bytes of the rendered prompt up to each `cache_control` breakpoint. A single byte difference at position N — a timestamp, a reordered JSON key, a different tool in the list — invalidates the cache for all breakpoints at positions ≥ N.\n\nRender order is: `tools` → `system` → `messages`. A breakpoint on the last system block caches both tools and system together.\n\nDesign the prompt-building path around this constraint. Get the ordering right and most caching works for free. Get it wrong and no amount of `cache_control` markers will help.\n\n---\n\n## Workflow for optimizing existing code\n\nWhen asked to add or optimize caching:\n\n1. **Trace the prompt assembly path.** Find where `system`, `tools`, and `messages` are constructed. Identify every input that flows into them.\n2. **Classify each input by stability:**\n - Never changes → belongs early in the prompt, before any breakpoint\n - Changes per-session → belongs after the global prefix, cache per-session\n - Changes per-turn → belongs at the end, after the last breakpoint\n - Changes per-request (timestamps, UUIDs, random IDs) → **eliminate or move to the very end**\n3. **Check rendered order matches stability order.** Stable content must physically precede volatile content. If a timestamp is interpolated into the system prompt header, everything after it is uncacheable regardless of markers.\n4. **Place breakpoints at stability boundaries.** See placement patterns below.\n5. **Audit for silent invalidators.** See anti-patterns table.\n\n---\n\n## Placement patterns\n\n### Large system prompt shared across many requests\n\nPut a breakpoint on the last system text block. If there are tools, they render before system — the marker on the last system block caches tools + system together.\n\n```json\n\"system\": [\n {\"type\": \"text\", \"text\": \"<large shared prompt>\", \"cache_control\": {\"type\": \"ephemeral\"}}\n]\n```\n\n### Multi-turn conversations\n\nPut a breakpoint on the last content block of the most-recently-appended turn. Each subsequent request reuses the entire prior conversation prefix. Earlier breakpoints remain valid read points, so hits accrue incrementally as the conversation grows.\n\n```json\n// Last content block of the last user turn\nmessages[-1].content[-1].cache_control = {\"type\": \"ephemeral\"}\n```\n\n### Shared prefix, varying suffix\n\nMany requests share a large fixed preamble (few-shot examples, retrieved docs, instructions) but differ in the final question. Put the breakpoint at the end of the **shared** portion, not at the end of the whole prompt — otherwise every request writes a distinct cache entry and nothing is ever read.\n\n```json\n\"messages\": [{\"role\": \"user\", \"content\": [\n {\"type\": \"text\", \"text\": \"<shared context>\", \"cache_control\": {\"type\": \"ephemeral\"}},\n {\"type\": \"text\", \"text\": \"<varying question>\"} // no marker — differs every time\n]}]\n```\n\n### Mid-conversation system messages\n\n**Claude Opus 4.8 only; no beta header.** When an operator instruction arrives mid-conversation — a mode switch, updated context, dynamically injected state — send it as `{\"role\": \"system\", \"content\": \"...\"}` appended to `messages[]`, rather than editing top-level `system`. Editing top-level `system` changes the prefix ahead of the entire conversation history, so every cached turn is re-processed uncached; a `role: \"system\"` message sits after the history and leaves the cached prefix intact.\n\n```json\n// Top-level system stays byte-identical; new instruction goes after the cached history\n\"system\": [{\"type\": \"text\", \"text\": \"<stable core>\", \"cache_control\": {\"type\": \"ephemeral\"}}],\n\"messages\": [\n ...history,\n {\"role\": \"user\", \"content\": \"...\"},\n {\"role\": \"system\", \"content\": \"Terse mode enabled — keep responses under 40 words.\"}\n]\n```\n\nThis is also the prompt-injection-safe replacement for embedding operator instructions as text inside a user turn (the `<system-reminder>` pattern): both have the same caching profile, but `role: \"system\"` is the non-spoofable operator channel, whereas text inside user/tool content can be forged by anything that writes to user-visible input.\n\nAvailable on Claude Opus 4.8; no beta header is required. Must follow a `role: \"user\"` message (or an `assistant` message ending in server-tool use), and must be either the last entry in `messages` or be followed by an `assistant` turn; cannot be `messages[0]` — use top-level `system` for the initial prompt. Content is text-only. Unsupported models return a 400 (`BadRequestError`: `role 'system' is not supported on this model`); catch that error and fall back to putting the instruction in a user-turn `<system-reminder>` block.\n\n### Prompts that change from the beginning every time\n\nDon't cache. If the first 1K tokens differ per request, there is no reusable prefix. Adding `cache_control` only pays the cache-write premium with zero reads. Leave it off.\n\n---\n\n## Architectural guidance\n\nThese are the decisions that matter more than marker placement. Fix these first.\n\n**Keep the system prompt frozen.** Don't interpolate \"current date: X\", \"mode: Y\", \"user name: Z\" into the system prompt — those sit at the front of the prefix and invalidate everything downstream. Inject dynamic context later in `messages` instead — as a `{\"role\": \"system\", ...}` message where supported (see § Mid-conversation system messages above), or as text in a user message otherwise. A message at turn 5 invalidates nothing before turn 5.\n\n**Don't change tools or model mid-conversation.** Tools render at position 0; adding, removing, or reordering a tool invalidates the entire cache. Same for switching models (caches are model-scoped). If you need \"modes\", don't swap the tool set — give Claude a tool that records the mode transition, or pass the mode as message content. Serialize tools deterministically (sort by name).\n\n**Fork operations must reuse the parent's exact prefix.** Side computations (summarization, compaction, sub-agents) often spin up a separate API call. If the fork rebuilds `system` / `tools` / `model` with any difference, it misses the parent's cache entirely. Copy the parent's `system`, `tools`, and `model` verbatim, then append fork-specific content at the end.\n\n---\n\n## Silent invalidators\n\nWhen reviewing code, grep for these inside anything that feeds the prompt prefix:\n\n| Pattern | Why it breaks caching |\n|---|---|\n| `datetime.now()` / `Date.now()` / `time.time()` in system prompt | Prefix changes every request |\n| `uuid4()` / `crypto.randomUUID()` / request IDs early in content | Same — every request is unique |\n| `json.dumps(d)` without `sort_keys=True` / iterating a `set` | Non-deterministic serialization → prefix bytes differ |\n| f-string interpolating session/user ID into system prompt | Per-user prefix; no cross-user sharing |\n| Conditional system sections (`if flag: system += ...`) | Every flag combination is a distinct prefix |\n| `tools=build_tools(user)` where set varies per user | Tools render at position 0; nothing caches across users |\n\nFix by moving the dynamic piece after the last breakpoint, making it deterministic, or deleting it if it's not load-bearing.\n\n---\n\n## API reference\n\n```json\n\"cache_control\": {\"type\": \"ephemeral\"} // 5-minute TTL (default)\n\"cache_control\": {\"type\": \"ephemeral\", \"ttl\": \"1h\"} // 1-hour TTL\n```\n\n- Max **4** `cache_control` breakpoints per request.\n- Goes on any content block: system text blocks, tool definitions, message content blocks (`text`, `image`, `tool_use`, `tool_result`, `document`).\n- Top-level `cache_control` on `messages.create()` auto-places on the last cacheable block — simplest option when you don't need fine-grained placement.\n- Minimum cacheable prefix is model-dependent. Shorter prefixes silently won't cache even with a marker — no error, just `cache_creation_input_tokens: 0`:\n\n| Model | Minimum |\n|---|---:|\n| Opus 4.8, Opus 4.7, Opus 4.6, Opus 4.5, Haiku 4.5 | 4096 tokens |\n| Fable 5, Sonnet 4.6, Haiku 3.5, Haiku 3 | 2048 tokens |\n| Sonnet 4.5, Sonnet 4.1, Sonnet 4, Sonnet 3.7 | 1024 tokens |\n\nA 3K-token prompt caches on Sonnet 4.5 and Fable 5 but silently won't on Opus 4.8.\n\n**Economics:** Cache reads cost ~0.1× base input price. Cache writes cost **1.25× for 5-minute TTL, 2× for 1-hour TTL**. Break-even depends on TTL: with 5-minute TTL, two requests break even (1.25× + 0.1× = 1.35× vs 2× uncached); with 1-hour TTL, you need at least three requests (2× + 0.2× = 2.2× vs 3× uncached). The 1-hour TTL keeps entries alive across gaps in bursty traffic, but the doubled write cost means it needs more reads to pay off.\n\n---\n\n## Verifying cache hits\n\nThe response `usage` object reports cache activity:\n\n| Field | Meaning |\n|---|---|\n| `cache_creation_input_tokens` | Tokens written to cache this request (you paid the ~1.25× write premium) |\n| `cache_read_input_tokens` | Tokens served from cache this request (you paid ~0.1×) |\n| `input_tokens` | Tokens processed at full price (not cached) |\n\nIf `cache_read_input_tokens` is zero across repeated requests with identical prefixes, a silent invalidator is at work — diff the rendered prompt bytes between two requests to find it.\n\n**`input_tokens` is the uncached remainder only.** Total prompt size = `input_tokens + cache_creation_input_tokens + cache_read_input_tokens`. If your agent ran for hours but `input_tokens` shows 4K, the rest was served from cache — check the sum, not the single field.\n\nLanguage-specific access: `response.usage.cache_read_input_tokens` (Python/TS/Ruby), `$message->usage->cacheReadInputTokens` (PHP), `resp.Usage.CacheReadInputTokens` (Go/C#), `.usage().cacheReadInputTokens()` (Java).\n\n---\n\n## Invalidation hierarchy\n\nNot every parameter change invalidates everything. The API has three cache tiers, and changes only invalidate their own tier and below:\n\n| Change | Tools cache | System cache | Messages cache |\n|---|:---:|:---:|:---:|\n| Tool definitions (add/remove/reorder) | ❌ | ❌ | ❌ |\n| Model switch | ❌ | ❌ | ❌ |\n| `speed`, web-search, citations toggle | ✅ | ❌ | ❌ |\n| System prompt content | ✅ | ❌ | ❌ |\n| `tool_choice`, images, `thinking` enable/disable | ✅ | ✅ | ❌ |\n| Message content | ✅ | ✅ | ❌ |\n\nImplication: you can change `tool_choice` per-request or toggle `thinking` without losing the tools+system cache. Don't over-worry about these — only tool-definition and model changes force a full rebuild.\n\n---\n\n## 20-block lookback window\n\nEach breakpoint walks backward **at most 20 content blocks** to find a prior cache entry. If a single turn adds more than 20 blocks (common in agentic loops with many tool_use/tool_result pairs), the next request's breakpoint won't find the previous cache and silently misses.\n\nFix: place an intermediate breakpoint every ~15 blocks in long turns, or put the marker on a block that's within 20 of the previous turn's last cached block.\n\n---\n\n## Concurrent-request timing\n\nA cache entry becomes readable only after the first response **begins streaming**. N parallel requests with identical prefixes all pay full price — none can read what the others are still writing.\n\nFor fan-out patterns: send 1 request, await the first streamed token (not the full response), then fire the remaining N−1. They'll read the cache the first one just wrote.\n\n## Pre-warming the cache\n\nTo eliminate the cache-miss latency on the *first* real request, send a **`max_tokens: 0`** request at startup (or on an interval). The API runs prefill — writing the cache at your `cache_control` breakpoint — and returns immediately with `content: []`, `stop_reason: \"max_tokens\"`, and a populated `usage` block (zero output tokens billed; normal cache-write charge on `cache_creation_input_tokens`).\n\n**When to pre-warm** — pre-warming trades a cache-write charge *now* for lower TTFT on the *next* real request. It's worth it when all three hold: (a) first-request latency is user-visible (chat/voice/interactive — not background jobs), (b) the shared prefix is large enough that a cold write is noticeably slow, and (c) there's a moment *before* traffic to fire it — app startup, worker boot, post-deploy, start of a scheduled window.\n\n| Skip pre-warming when… | Because |\n|---|---|\n| Traffic is continuous (requests ≤ TTL apart) | The first real request warms the cache and every subsequent one hits it; a separate warm call is a pure extra write |\n| The prefix is small or below the cacheable minimum | The cold-write penalty is negligible |\n| The prefix varies per request/user | Nothing shared to pre-warm |\n| You'd pre-warm many distinct prefixes speculatively | Each is a ~1.25× write; cost can exceed the latency you save |\n\n**Scheduled re-warms:** only needed when traffic has gaps longer than the TTL. If real requests arrive more often than every 5 minutes, they keep the cache warm on their own — don't add an interval re-warm. For bursty traffic with long idle gaps, either re-warm just under the TTL or switch to `ttl: \"1h\"` and re-warm less often.\n\n```python\nclient.messages.create(\n model=\"claude-opus-4-8\",\n max_tokens=0,\n system=[{\n \"type\": \"text\",\n \"text\": SYSTEM_PROMPT,\n \"cache_control\": {\"type\": \"ephemeral\"},\n }],\n messages=[{\"role\": \"user\", \"content\": \"warmup\"}],\n)\n```\n\n**Breakpoint placement:** put `cache_control` on the **last block shared with the real request** (the system prompt or tool definitions) — **not** on the placeholder user message, and **not** via top-level automatic caching (which would key the cache to the placeholder). The placeholder can be any non-whitespace string; it's read during prefill but never answered.\n\n**Rejected combinations:** `max_tokens: 0` is an `invalid_request_error` with `stream: true`, `thinking.type: \"enabled\"`, `output_config.format`, `tool_choice` of `{\"type\":\"tool\"}` or `{\"type\":\"any\"}`, or inside a Message Batches request.\n\n**TTL still applies** — re-warm at least every 5 minutes for the default cache, or use the 1-hour TTL. This replaces the older `max_tokens: 1` workaround (no single-token reply to discard, no output tokens billed, intent is unambiguous).\n</doc>\n\n<doc path=\"shared/token-counting.md\">\n# Token Counting\n\nUse the `count_tokens` endpoint (`POST /v1/messages/count_tokens`) for accurate\ntoken counts against Claude models. Token counts are **model-specific** — pass\nthe same model ID you'll use for inference.\n\n**Do not use `tiktoken`.** It's OpenAI's tokenizer. It undercounts Claude\ntokens by ~15–20% on typical text, and by much more on code or non-English\ninput. Any estimate from `tiktoken`, `gpt-tokenizer`, or similar is wrong for\nClaude.\n\n## Count a file or string\n\n```python\nfrom anthropic import Anthropic\n\nclient = Anthropic()\nresp = client.messages.count_tokens(\n model=\"claude-opus-4-8\",\n messages=[{\"role\": \"user\", \"content\": open(\"CLAUDE.md\").read()}],\n)\nprint(resp.input_tokens)\n```\n\nTypeScript: `await client.messages.countTokens({model, messages})` →\n`.input_tokens`.

For language-specific code examples, see the `python/`, `typescript/`, or other language folders. For decision heuristics on which tools to expose, how to manage context in long-running agents, and caching strategy, see `agent-design.md`.\n\n## User-Defined Tools\n\n### Tool Definition Structure\n\n> **Note:** When using the Tool Runner (beta), tool schemas are generated automatically from your function signatures (Python), Zod schemas (TypeScript), annotated classes (Java), `jsonschema` struct tags (Go), or `BaseTool` subclasses (Ruby). The raw JSON schema format below is for the manual approach — including PHP's `BetaRunnableTool`, which wraps a run closure around a hand-written schema — or SDKs without tool runner support.\n\nEach tool requires a name, description, and JSON Schema for its inputs:\n\n```json\n{\n \"name\": \"get_weather\",\n \"description\": \"Get current weather for a location\",\n \"input_schema\": {\n \"type\": \"object\",\n \"properties\": {\n \"location\": {\n \"type\": \"string\",\n \"description\": \"City and state, e.g., San Francisco, CA\"\n },\n \"unit\": {\n \"type\": \"string\",\n \"enum\": [\"celsius\", \"fahrenheit\"],\n \"description\": \"Temperature unit\"\n }\n },\n \"required\": [\"location\"]\n }\n}\n```\n\n**Best practices for tool definitions:**\n\n- Use clear, descriptive names (e.g., `get_weather`, `search_database`, `send_email`)\n- Write detailed descriptions — Claude uses these to decide when to use the tool. Be **prescriptive about *when* to call it**, not just what it does (e.g. \"Call this when the user asks about current prices or recent events\"). On recent Opus models, which reach for tools more conservatively, trigger conditions in the description give measurable lift in should-call rate.\n- Include descriptions for each property\n- Use `enum` for parameters with a fixed set of values\n- Mark truly required parameters in `required`; make others optional with defaults\n\n---\n\n### Tool Choice Options\n\nControl when Claude uses tools:\n\n| Value | Behavior |\n| --------------------------------- | --------------------------------------------- |\n| `{\"type\": \"auto\"}` | Claude decides whether to use tools (default) |\n| `{\"type\": \"any\"}` | Claude must use at least one tool |\n| `{\"type\": \"tool\", \"name\": \"...\"}` | Claude must use the specified tool |\n| `{\"type\": \"none\"}` | Claude cannot use tools |\n\nAny `tool_choice` value can also include `\"disable_parallel_tool_use\": true` to force Claude to use at most one tool per response. By default, Claude may request multiple tool calls in a single response.\n\n---\n\n### Tool Runner vs Manual Loop\n\n**Tool Runner (Recommended):** The SDK's tool runner handles the agentic loop automatically — it calls the API, detects tool use requests, executes your tool functions, feeds results back to Claude, and repeats until Claude stops calling tools. Available in Python, TypeScript, Java, Go, Ruby, and PHP SDKs (beta). The Python SDK also provides MCP conversion helpers (`anthropic.lib.tools.mcp`) to convert MCP tools, prompts, and resources for use with the tool runner — see `python/claude-api/tool-use.md` for details.\n\n**Manual Agentic Loop:** Use when you need fine-grained control over the loop (e.g., custom logging, conditional tool execution, human-in-the-loop approval). Loop until `stop_reason == \"end_turn\"`, always append the full `response.content` to preserve tool_use blocks, and ensure each `tool_result` includes the matching `tool_use_id`.\n\n**Stop reasons for server-side tools:** When using server-side tools (code execution, web search, etc.), the API runs a server-side sampling loop. If this loop reaches its default limit of 10 iterations, the response will have `stop_reason: \"pause_turn\"`. To continue, re-send the user message and assistant response and make another API request — the server will resume where it left off. Do NOT add an extra user message like \"Continue.\" — the API detects the trailing `server_tool_use` block and knows to resume automatically.\n\n```python\n# Handle pause_turn in your agentic loop\nif response.stop_reason == \"pause_turn\":\n messages = [\n {\"role\": \"user\", \"content\": user_query},\n {\"role\": \"assistant\", \"content\": response.content},\n ]\n # Make another API request — server resumes automatically\n response = client.messages.create(\n model=\"claude-opus-4-8\", messages=messages, tools=tools\n )\n```\n\nSet a `max_continuations` limit (e.g., 5) to prevent infinite loops. For the full guide, see: `https://platform.claude.com/docs/en/build-with-claude/handling-stop-reasons`\n\n> **Security:** The tool runner executes your tool functions automatically whenever Claude requests them. For tools with side effects (sending emails, modifying databases, financial transactions), validate inputs within your tool functions and consider requiring confirmation for destructive operations. Use the manual agentic loop if you need human-in-the-loop approval before each tool execution.\n\n---\n\n### Handling Tool Results\n\nWhen Claude uses a tool, the response contains a `tool_use` block. You must:\n\n1. Execute the tool with the provided input\n2. Send the result back in a `tool_result` message\n3. Continue the conversation\n\n**Error handling in tool results:** When a tool execution fails, set `\"is_error\": true` and provide an informative error message. Claude will typically acknowledge the error and either try a different approach or ask for clarification.\n\n**Multiple tool calls:** Claude can request multiple tools in a single response. Handle them all before continuing — send all results back in a single `user` message.\n\n---\n\n## Server-Side Tools: Code Execution\n\nThe code execution tool lets Claude run code in a secure, sandboxed container. Unlike user-defined tools, server-side tools run on Anthropic's infrastructure — you don't execute anything client-side. Just include the tool definition and Claude handles the rest.\n\n### Key Facts\n\n- Runs in an isolated container (1 CPU, 5 GiB RAM, 5 GiB disk)\n- No internet access (fully sandboxed)\n- Python 3.11 with data science libraries pre-installed\n- Containers persist for 30 days and can be reused across requests\n- Free when used with web search/web fetch tools; otherwise $0.05/hour after 1,550 free hours/month per organization\n\n### Tool Definition\n\nThe tool requires no schema — just declare it in the `tools` array:\n\n```json\n{\n \"type\": \"code_execution_20260120\",\n \"name\": \"code_execution\"\n}\n```\n\nClaude automatically gains access to `bash_code_execution` (run shell commands) and `text_editor_code_execution` (create/view/edit files).\n\n### Pre-installed Python Libraries\n\n- **Data science**: pandas, numpy, scipy, scikit-learn, statsmodels\n- **Visualization**: matplotlib, seaborn\n- **File processing**: openpyxl, xlsxwriter, pillow, pypdf, pdfplumber, python-docx, python-pptx\n- **Math**: sympy, mpmath\n- **Utilities**: tqdm, python-dateutil, pytz, sqlite3\n\nAdditional packages can be installed at runtime via `pip install`.\n\n### Supported File Types for Upload\n\n| Type | Extensions |\n| ------ | ---------------------------------- |\n| Data | CSV, Excel (.xlsx/.xls), JSON, XML |\n| Images | JPEG, PNG, GIF, WebP |\n| Text | .txt, .md, .py, .js, etc. |\n\n### Container Reuse\n\nReuse containers across requests to maintain state (files, installed packages, variables). Extract the `container_id` from the first response and pass it to subsequent requests.\n\n### Response Structure\n\nThe response contains interleaved text and tool result blocks:\n\n- `text` — Claude's explanation\n- `server_tool_use` — What Claude is doing\n- `bash_code_execution_tool_result` — Code execution output (check `return_code` for success/failure)\n- `text_editor_code_execution_tool_result` — File operation results\n\n> **Security:** Always sanitize filenames with `os.path.basename()` / `path.basename()` before writing downloaded files to disk to prevent path traversal attacks. Write files to a dedicated output directory.\n\n---\n\n## Server-Side Tools: Web Search and Web Fetch\n\nWeb search and web fetch let Claude search the web and retrieve page content. They run server-side — just include the tool definitions and Claude handles queries, fetching, and result processing automatically.\n\n### Tool Definitions\n\n```json\n[\n { \"type\": \"web_search_20260209\", \"name\": \"web_search\" },\n { \"type\": \"web_fetch_20260209\", \"name\": \"web_fetch\" }\n]\n```\n\n### Dynamic Filtering (Fable 5 / Opus 4.8 / Opus 4.7 / Opus 4.6 / Sonnet 4.6)\n\nThe `web_search_20260209` and `web_fetch_20260209` versions support **dynamic filtering** — Claude writes and executes code to filter search results before they reach the context window, improving accuracy and token efficiency. Dynamic filtering is built into these tool versions and activates automatically; you do not need to separately declare the `code_execution` tool or pass any beta header.\n\n```json\n{\n \"tools\": [\n { \"type\": \"web_search_20260209\", \"name\": \"web_search\" },\n { \"type\": \"web_fetch_20260209\", \"name\": \"web_fetch\" }\n ]\n}\n```\n\nWithout dynamic filtering, the previous `web_search_20250305` version is also available.\n\n> **Note:** Only include the standalone `code_execution` tool when your application needs code execution for its own purposes (data analysis, file processing, visualization) independent of web search. Including it alongside `_20260209` web tools creates a second execution environment that can confuse the model.\n\n---\n\n## Server-Side Tools: Programmatic Tool Calling\n\nWith standard tool use, each tool call is a round trip: Claude calls, the result enters Claude's context, Claude reasons, then calls the next tool. Chained calls accumulate latency and tokens — most of that intermediate data is never needed again.\n\nProgrammatic tool calling lets Claude compose those calls into a script. The script runs in the code execution container; when it invokes a tool, the container pauses, the call executes, and the result returns to the running code (not to Claude's context). The script processes it with normal control flow. Only the final output returns to Claude. Use it when chaining many tool calls or when intermediate results are large and should be filtered before reaching the context window.\n\nFor full documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/agents-and-tools/tool-use/programmatic-tool-calling`\n\n---\n\n## Server-Side Tools: Tool Search\n\nThe tool search tool lets Claude dynamically discover tools from large libraries without loading all definitions into the context window. Use it when you have many tools but only a few are relevant to any given request. Discovered tool schemas are appended to the request, not swapped in — this preserves the prompt cache (see `agent-design.md` §Caching for Agents).\n\nFor full documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-search-tool`\n\n---\n\n## Agent Skills (Messages API)\n\nAgent Skills package task-specific instructions and files that Claude loads when relevant (e.g., the Anthropic pre-built `pptx`, `xlsx`, `pdf`, `docx` skills). On the **Messages API**, skills are enabled via the `container` parameter alongside the code-execution tool — this is **not** the Managed Agents surface and does **not** use `client.beta.agents` / `sessions` / `environments`. Availability: see `shared/platform-availability.md`.\n\nRequired on each request:\n\n1. `client.beta.messages.create(...)` with **both** beta flags: `code-execution-2025-08-25` **and** `skills-2025-10-02`.\n2. `container={\"skills\": [{\"type\": \"anthropic\", \"skill_id\": \"<id>\", \"version\": \"latest\"}]}` — the skills list selects which skills are available inside the execution container.\n3. `tools=[{\"type\": \"code_execution_20260521\", \"name\": \"code_execution\"}]` — skills execute via code execution in the container.\n\n```python\nresponse = client.beta.messages.create(\n model=\"claude-opus-4-8\", max_tokens=16000,\n betas=[\"code-execution-2025-08-25\", \"skills-2025-10-02\"],\n container={\"skills\": [{\"type\": \"anthropic\", \"skill_id\": \"pptx\", \"version\": \"latest\"}]},\n tools=[{\"type\": \"code_execution_20260521\", \"name\": \"code_execution\"}],\n messages=[{\"role\": \"user\", \"content\": \"Create a 3-slide presentation on X\"}],\n)\n```\n\nGenerated files (`.pptx`, `.xlsx`, …) are written inside the container; the response carries a file ID for each. Download by passing that ID to the Files API (`client.beta.files.download(file_id)` / `GET /v1/files/{id}/content` with `anthropic-beta: files-api-2025-04-14`).\n\nList available skills via `GET /v1/skills` (requires `anthropic-beta: skills-2025-10-02`).\n\n---\n\n## MCP Connector (Beta)\n\nThe MCP connector lets Claude call tools hosted on a remote MCP server directly from the Messages API — Anthropic makes the MCP connection server-side. Requires beta flag `mcp-client-2025-11-20` on `client.beta.messages.create(...)`. Availability: see `shared/platform-availability.md`.\n\n**Two parameters are required together:**\n\n- `mcp_servers` — array of server connection definitions: `[{\"type\": \"url\", \"url\": \"<server URL>\", \"name\": \"<server-name>\", \"authorization_token\": \"<optional>\"}]`\n- `tools` — must include an `mcp_toolset` entry that references the server by name: `[{\"type\": \"mcp_toolset\", \"mcp_server_name\": \"<server-name>\"}]`\n\nThe `mcp_server_name` in the toolset must match a `name` in `mcp_servers`. Omitting the `mcp_toolset` entry is rejected as a validation error — every server in `mcp_servers` must be referenced by exactly one toolset.\n\n```python\nclient.beta.messages.create(\n model=\"claude-opus-4-8\", max_tokens=1024,\n betas=[\"mcp-client-2025-11-20\"],\n mcp_servers=[{\"type\": \"url\", \"url\": \"https://example/sse\", \"name\": \"example-mcp\"}],\n tools=[{\"type\": \"mcp_toolset\", \"mcp_server_name\": \"example-mcp\"}],\n messages=[...],\n)\n```\n\nGo uses the typed constant `anthropic.AnthropicBetaMCPClient2025_11_20`; the older `…2025_04_04` constant is deprecated.\n\nOptional toolset fields: `default_config` (defaults for all tools, e.g. `{\"enabled\": false}` for allowlist mode) and `configs` (per-tool overrides keyed by tool name).\n\n---\n\n## Tool Use Examples\n\nYou can provide sample tool calls directly in your tool definitions to demonstrate usage patterns and reduce parameter errors. This helps Claude understand how to correctly format tool inputs, especially for tools with complex schemas.\n\nFor full documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/agents-and-tools/tool-use/implement-tool-use`\n\n---\n\n## Client-Side Tools: Computer Use\n\nComputer use lets Claude interact with a desktop environment (screenshots, mouse, keyboard). It is a client-side tool — your application provides the environment and executes the actions Claude requests; Anthropic processes the screenshots and action requests in real time but does not host the environment or retain the data.\n\nFor full documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/agents-and-tools/computer-use/overview`\n\n---\n\n## Context Editing\n\nContext editing clears stale tool results and thinking blocks from the transcript as a long-running agent accumulates turns. Unlike compaction (which summarizes), context editing prunes — the cleared content is removed, not replaced. Use it when old tool outputs are no longer relevant and you want to keep the transcript lean without losing the conversation structure.\n\n**Beta.** Use `client.beta.messages.*` with beta `context-management-2025-06-27`. Configure via `context_management.edits` with a strategy type of `clear_tool_uses_20250919` (clear old tool results; optional `clear_tool_inputs: true` also clears the tool_use params) or `clear_thinking_20251015` (clear thinking blocks). These are **not** the compaction types — `compact_20260112` with beta `compact-2026-01-12` is the separate compaction feature.\n\nFor full documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/build-with-claude/context-editing`\n\n---\n\n## Server-Side Tools: Advisor (Beta)\n\nThe advisor tool pairs a faster, lower-cost **executor** model (the top-level `model` on the request) with a higher-intelligence **advisor** model (the `model` field inside the tool definition) that provides strategic guidance mid-generation. The executor does most of the token generation; the advisor is consulted for planning. Availability: see `shared/platform-availability.md`.\n\n### Tool Definition\n\n```json\n{\n \"type\": \"advisor_20260301\",\n \"name\": \"advisor\",\n \"model\": \"claude-opus-4-8\"\n}\n```\n\n**The advisor model must be at least as capable as the executor.** An invalid pairing returns `400 invalid_request_error`. Valid pairs:\n\n| Executor (request `model`) | Valid advisor (tool `model`) |\n|---|---|\n| `claude-haiku-4-5` / `claude-sonnet-4-6` / `claude-sonnet-5` / `claude-opus-4-6` / `claude-opus-4-7` | `claude-opus-4-8` or `claude-opus-4-7` |\n| `claude-opus-4-8` | `claude-opus-4-8` only |\n\nCall via `client.beta.messages.create(...)` with `betas=[\"advisor-tool-2026-03-01\"]` (or the `anthropic-beta: advisor-tool-2026-03-01` header). In multi-turn conversations, append the full `response.content` — including any `advisor_tool_result` blocks — back to `messages` on the next turn. If you remove the advisor tool from `tools` on a later turn while the history still contains `advisor_tool_result` blocks, the API returns a 400.\n\n---\n\n## Client-Side Tools: Memory\n\nThe memory tool enables Claude to store and retrieve information across conversations through a memory file directory. Claude can create, read, update, and delete files that persist between sessions.\n\n### Key Facts\n\n- Client-side tool — you control storage via your implementation\n- Supports commands: `view`, `create`, `str_replace`, `insert`, `delete`, `rename`\n- Operates on files in a `/memories` directory\n- The Python, TypeScript, and Java SDKs provide helper classes/functions for implementing the memory backend\n\n> **Security:** Never store API keys, passwords, tokens, or other secrets in memory files. Be cautious with personally identifiable information (PII) — check data privacy regulations (GDPR, CCPA) before persisting user data. The reference implementations have no built-in access control; in multi-user systems, implement per-user memory directories and authentication in your tool handlers.\n\nFor full implementation examples, use WebFetch:\n\n- Docs: `https://platform.claude.com/docs/en/agents-and-tools/tool-use/memory-tool.md`\n\n---\n\n## Client-Side Tools: Bash and Text Editor\n\nThe bash and text editor tools are **Anthropic-defined, schema-less** tools. Declare them by `type` and `name` only — the input schema is built into the model and cannot be modified. **Do not pass an `input_schema`**, and do not define a custom tool that happens to be named `\"bash\"` — that creates a user-defined tool without the built-in behavior.\n\nBoth are **client-executed**: Claude returns a `tool_use` block, your code performs the action locally, and you send back a `tool_result`. The API is stateless; your application maintains the shell session or filesystem between turns.\n\n### Bash tool declaration\n\n```json\n{\"type\": \"bash_20250124\", \"name\": \"bash\"}\n```\n\n| Language | Declaration |\n|---|---|\n| Python / TypeScript / Ruby / cURL | plain object `{\"type\": \"bash_20250124\", \"name\": \"bash\"}` |\n| Go | `anthropic.ToolUnionParam{OfBashTool20250124: &anthropic.ToolBash20250124Param{}}` |\n| Java | `.addTool(ToolBash20250124.builder().build())` from `com.anthropic.models.messages` |\n| C# | `Tools = [new ToolBash20250124()]` from `Anthropic.Models.Messages` |\n| PHP | `tools: [new \\Anthropic\\Messages\\ToolBash20250124()]` |\n\nClaude's `tool_use.input` contains either `{\"command\": \"<string>\"}` or `{\"restart\": true}`. Check for `restart` first (reset the session, return a confirmation string); otherwise run `command` and return combined stdout + stderr.\n\n> **Security — commands are untrusted model output.** Run in an isolated environment (container, VM, or restricted user); apply an **allowlist** of permitted executables and reject shell operators (`&&`, `|`, `;`, `` ` ``, `$()`); set timeouts and resource limits; log every command. A blocklist is not sufficient.\n\n### Text editor tool declaration\n\n```json\n{\"type\": \"text_editor_20250728\", \"name\": \"str_replace_based_edit_tool\"}\n```\n\nOptional field: `max_characters` to cap `view` output. Java exposes a typed `ToolTextEditor20250728` builder (`com.anthropic.models.messages`); other statically-typed SDKs follow the same naming pattern — see the Anthropic-Defined Tools section in `{lang}/claude-api/tool-use.md` for the exact class.\n\n> **Security — `path` is untrusted model output. Confine every file operation to a fixed project root.** Before executing any command, resolve the model-supplied `path` to its canonical form and verify it remains within your project root; reject the request if it escapes (`..`, symlinks, absolute paths outside the root, URL-encoded traversal like `%2e%2e%2f`). Use your language's built-in path utilities (e.g., Python `pathlib.Path.resolve()` then check `.is_relative_to(root)`). Never call `open()` / `writeFile` / `unlink` directly on the raw `path` value.\n\n`tool_use.input.command` is one of:\n\n| `command` | Other inputs | Action |\n|---|---|---|\n| `view` | `path`, optional `view_range` | Return file contents or directory listing |\n| `create` | `path`, `file_text` | Create/overwrite file with `file_text`. Create a backup if the file already exists. |\n| `str_replace` | `path`, `old_str`, `new_str` | Replace exactly one occurrence; error if 0 or >1 matches |\n| `insert` | `path`, `insert_line`, `insert_text` | Insert `insert_text` after line `insert_line` (0 = beginning of file) |\n\nFor both tools, on error return `{\"type\": \"tool_result\", \"tool_use_id\": \"…\", \"content\": \"<error text>\", \"is_error\": true}` so Claude can recover.\n\n---\n\n## Structured Outputs\n\nStructured outputs constrain Claude's responses to follow a specific JSON schema, guaranteeing valid, parseable output. This is not a separate tool — it enhances the Messages API response format and/or tool parameter validation.\n\nTwo features are available:\n\n- **JSON outputs** (`output_config.format`): Control Claude's response format\n- **Strict tool use** (`strict: true`): Guarantee valid tool parameter schemas\n\n**Supported models:** Claude Fable 5, Claude Opus 4.8, Claude Sonnet 5, and Claude Haiku 4.5. Legacy models (Claude Opus 4.5, Claude Opus 4.1) also support structured outputs.\n\n> **Recommended:** Use `client.messages.parse()` which automatically validates responses against your schema. When using `messages.create()` directly, use `output_config: {format: {...}}`. The `output_format` convenience parameter is also accepted by some SDK methods (e.g., `.parse()`), but `output_config.format` is the canonical API-level parameter.\n\n### JSON Schema Limitations\n\n**Supported:**\n\n- Basic types: object, array, string, integer, number, boolean, null\n- `enum`, `const`, `anyOf`, `allOf`, `$ref`/`$def`\n- String formats: `date-time`, `time`, `date`, `duration`, `email`, `hostname`, `uri`, `ipv4`, `ipv6`, `uuid`\n- `additionalProperties: false` (required for all objects)\n\n**Not supported:**\n\n- Recursive schemas\n- Numerical constraints (`minimum`, `maximum`, `multipleOf`)\n- String constraints (`minLength`, `maxLength`)\n- Complex array constraints\n- `additionalProperties` set to anything other than `false`\n\nThe Python and TypeScript SDKs automatically handle unsupported constraints by removing them from the schema sent to the API and validating them client-side.\n\n### Important Notes\n\n- **First request latency**: New schemas incur a one-time compilation cost. Subsequent requests with the same schema use a 24-hour cache.\n- **Refusals**: If Claude refuses for safety reasons (`stop_reason: \"refusal\"`), the output may not match your schema.\n- **Token limits**: If `stop_reason: \"max_tokens\"`, output may be incomplete. Increase `max_tokens`.\n- **Incompatible with**: Citations (returns 400 error), message prefilling.\n- **Works with**: Batches API, streaming, token counting, extended thinking.\n\n---\n\n## Tips for Effective Tool Use\n\n1. **Provide detailed descriptions**: Claude relies heavily on descriptions to understand when and how to use tools\n2. **Use specific tool names**: `get_current_weather` is better than `weather`\n3. **Validate inputs**: Always validate tool inputs before execution\n4. **Handle errors gracefully**: Return informative error messages so Claude can adapt\n5. **Limit tool count**: Too many tools can confuse the model — keep the set focused\n6. **Test tool interactions**: Verify Claude uses tools correctly in various scenarios\n\nFor detailed tool use documentation, use WebFetch:\n\n- URL: `https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview`\n</doc>\n\n<doc path=\"typescript/claude-api/README.md\">\n# Claude API — TypeScript\n\n| Feature | Namespace | Key types / call |\n|---|---|---|\n| User profiles | beta | `client.beta.userProfiles.create(...)` / `.retrieve(id)` / `.list()`. Pass the returned profile id on `client.beta.messages.create`. Requires a beta header — check the SDK's beta-headers reference for the current flag. |\n\n## Installation\n\n```bash\nnpm install @anthropic-ai/sdk\n```\n\n> **Reading local files (ESM):** `__dirname` and `__filename` are **undefined** in ES modules — using either throws `ReferenceError: __dirname is not defined` at runtime. For cwd-relative reads, pass the bare relative path (`fs.readFileSync(\"./sample.png\")`). For script-relative paths, derive the directory from `import.meta.url`: `const here = path.dirname(fileURLToPath(import.meta.url))`. Never write `path.join(__dirname, …)` in an ESM `.ts` file.\n\n## Client Initialization\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\n// Default — resolves credentials from the environment:\n// ANTHROPIC_API_KEY, or ANTHROPIC_AUTH_TOKEN, or an `ant auth login` profile.\n// Prefer this for local dev; don't hardcode a key.\nconst client = new Anthropic();\n\n// Explicit API key (only when you must inject a specific key)\nconst client = new Anthropic({ apiKey: \"your-api-key\" });\n```\n\n---\n\n## Basic Message Request\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [{ role: \"user\", content: \"What is the capital of France?\" }],\n});\n// response.content is ContentBlock[] — a discriminated union. Narrow by .type\n// before accessing .text (TypeScript will error on content[0].text without this).\nfor (const block of response.content) {\n if (block.type === \"text\") {\n console.log(block.text);\n }\n}\n```\n\n---\n\n## System Prompts\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n system:\n \"You are a helpful coding assistant. Always provide examples in Python.\",\n messages: [{ role: \"user\", content: \"How do I read a JSON file?\" }],\n});\n```\n\n### Mid-conversation system messages (model-gated)\n\nFor operator instructions that arrive mid-conversation (mode switches, injected state), append `{role: \"system\", ...}` to `messages` instead of editing top-level `system` — this preserves the cached prefix and carries operator authority. Must follow a user message (or an `assistant` message ending in server-tool use), and must be either the last entry in `messages` or be followed by an `assistant` turn; cannot be `messages[0]`. Unsupported models return a 400 (`role 'system' is not supported on this model`). See `shared/prompt-caching.md` for when to use this vs. top-level `system`.\n\n```typescript\n// No beta header needed — use regular client.messages.create.\nconst response = await client.messages.create({\n model: MODEL_ID, // must support mid-conversation system messages\n max_tokens: 16000,\n system: [\n { type: \"text\", text: STABLE_SYSTEM, cache_control: { type: \"ephemeral\" } },\n ],\n messages: [\n ...history,\n { role: \"user\", content: userMessage },\n { role: \"system\", content: \"Terse mode enabled — keep responses under 40 words.\" },\n ],\n});\n```\n\n---\n\n## Vision (Images)\n\n### URL\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [\n {\n role: \"user\",\n content: [\n {\n type: \"image\",\n source: { type: \"url\", url: \"https://example.com/image.png\" },\n },\n { type: \"text\", text: \"Describe this image\" },\n ],\n },\n ],\n});\n```\n\n### Base64\n\n```typescript\nimport fs from \"fs\";\n\nconst imageData = fs.readFileSync(\"image.png\").toString(\"base64\");\n\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [\n {\n role: \"user\",\n content: [\n {\n type: \"image\",\n source: { type: \"base64\", media_type: \"image/png\", data: imageData },\n },\n { type: \"text\", text: \"What's in this image?\" },\n ],\n },\n ],\n});\n```\n\n---\n\n## Prompt Caching\n\n**Caching is a prefix match** — any byte change anywhere in the prefix invalidates everything after it. For placement patterns, architectural guidance (frozen system prompt, deterministic tool order, where to put volatile content), and the silent-invalidator audit checklist, read `shared/prompt-caching.md`.\n\n### Automatic Caching (Recommended)\n\nUse top-level `cache_control` to automatically cache the last cacheable block in the request:\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n cache_control: { type: \"ephemeral\" }, // auto-caches the last cacheable block\n system: \"You are an expert on this large document...\",\n messages: [{ role: \"user\", content: \"Summarize the key points\" }],\n});\n```\n\n### Manual Cache Control\n\nFor fine-grained control, add `cache_control` to specific content blocks:\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n system: [\n {\n type: \"text\",\n text: \"You are an expert on this large document...\",\n cache_control: { type: \"ephemeral\" }, // default TTL is 5 minutes\n },\n ],\n messages: [{ role: \"user\", content: \"Summarize the key points\" }],\n});\n\n// With explicit TTL (time-to-live)\nconst response2 = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n system: [\n {\n type: \"text\",\n text: \"You are an expert on this large document...\",\n cache_control: { type: \"ephemeral\", ttl: \"1h\" }, // 1 hour TTL\n },\n ],\n messages: [{ role: \"user\", content: \"Summarize the key points\" }],\n});\n```\n\n### Verifying Cache Hits\n\n```typescript\nconsole.log(response.usage.cache_creation_input_tokens); // tokens written to cache (~1.25x cost)\nconsole.log(response.usage.cache_read_input_tokens); // tokens served from cache (~0.1x cost)\nconsole.log(response.usage.input_tokens); // uncached tokens (full cost)\n```\n\nIf `cache_read_input_tokens` is zero across repeated identical-prefix requests, a silent invalidator is at work — `Date.now()` or a UUID in the system prompt, non-deterministic key ordering, or a varying tool set. See `shared/prompt-caching.md` for the full audit table.\n\n---\n\n## Extended Thinking\n\n> **Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6:** Use adaptive thinking. `budget_tokens` is removed on Fable 5, Opus 4.8, and 4.7 (400 if sent); deprecated on Opus 4.6 and Sonnet 4.6.\n> **Older models:** Use `thinking: {type: \"enabled\", budget_tokens: N}` (must be < `max_tokens`, min 1024).\n\n```typescript\n// Fable 5 / Opus 4.8 / 4.7 / 4.6: adaptive thinking (recommended)\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n thinking: { type: \"adaptive\", display: \"summarized\" }, // display opt-in: default is omitted (empty thinking text) on Fable 5 / Mythos 5 / Opus 4.8 / 4.7\n output_config: { effort: \"high\" }, // low | medium | high | max\n messages: [\n { role: \"user\", content: \"Solve this math problem step by step...\" },\n ],\n});\n\nfor (const block of response.content) {\n if (block.type === \"thinking\") {\n console.log(\"Thinking:\", block.thinking);\n } else if (block.type === \"text\") {\n console.log(\"Response:\", block.text);\n }\n}\n```\n\n---\n\n## Error Handling\n\nUse the SDK's typed exception classes — never check error messages with string matching:\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\ntry {\n const response = await client.messages.create({...});\n} catch (error) {\n if (error instanceof Anthropic.BadRequestError) {\n console.error(\"Bad request:\", error.message);\n } else if (error instanceof Anthropic.AuthenticationError) {\n console.error(\"Invalid API key\");\n } else if (error instanceof Anthropic.RateLimitError) {\n console.error(\"Rate limited - retry later\");\n } else if (error instanceof Anthropic.APIError) {\n console.error(`API error ${error.status}:`, error.message);\n }\n}\n```\n\nAll classes extend `Anthropic.APIError` with a typed `status` field. Check from most specific to least specific. See [shared/error-codes.md](../../shared/error-codes.md) for the full error code reference.\n\n---\n\n## Multi-Turn Conversations\n\nThe API is stateless — send the full conversation history each time. Use `Anthropic.MessageParam[]` to type the messages array:\n\n```typescript\nconst messages: Anthropic.MessageParam[] = [\n { role: \"user\", content: \"My name is Alice.\" },\n { role: \"assistant\", content: \"Hello Alice! Nice to meet you.\" },\n { role: \"user\", content: \"What's my name?\" },\n];\n\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: messages,\n});\n```\n\n**Rules:**\n\n- Consecutive same-role messages are allowed — the API combines them into a single turn\n- First message must be `user`\n- Use SDK types (`Anthropic.MessageParam`, `Anthropic.Message`, `Anthropic.Tool`, etc.) for all API data structures — don't redefine equivalent interfaces\n\n---\n\n### Compaction (long conversations)\n\n> **Beta, Fable 5, Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6.** When conversations approach the 200K context window, compaction automatically summarizes earlier context server-side. The API returns a `compaction` block; you must pass it back on subsequent requests — append `response.content`, not just the text.\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\nconst client = new Anthropic();\nconst messages: Anthropic.Beta.BetaMessageParam[] = [];\n\nasync function chat(userMessage: string): Promise<string> {\n messages.push({ role: \"user\", content: userMessage });\n\n const response = await client.beta.messages.create({\n betas: [\"compact-2026-01-12\"],\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages,\n context_management: {\n edits: [{ type: \"compact_20260112\" }],\n },\n });\n\n // Append full content — compaction blocks must be preserved\n messages.push({ role: \"assistant\", content: response.content });\n\n const textBlock = response.content.find(\n (b): b is Anthropic.Beta.BetaTextBlock => b.type === \"text\",\n );\n return textBlock?.text ?? \"\";\n}\n\n// Compaction triggers automatically when context grows large\nconsole.log(await chat(\"Help me build a Python web scraper\"));\nconsole.log(await chat(\"Add support for JavaScript-rendered pages\"));\nconsole.log(await chat(\"Now add rate limiting and error handling\"));\n```\n\n---\n\n## Stop Reasons\n\nThe `stop_reason` field in the response indicates why the model stopped generating:\n\n| Value | Meaning |\n| --------------- | --------------------------------------------------------------- |\n| `end_turn` | Claude finished its response naturally |\n| `max_tokens` | Hit the `max_tokens` limit — increase it or use streaming |\n| `stop_sequence` | Hit a custom stop sequence |\n| `tool_use` | Claude wants to call a tool — execute it and continue |\n| `pause_turn` | Model paused and can be resumed (agentic flows) |\n| `refusal` | Claude refused for safety reasons — check `stop_details` |\n\n### Structured Stop Details\n\nWhen `stop_reason` is `\"refusal\"`, the response includes a `stop_details` object with structured information about the refusal:\n\n```typescript\nif (response.stop_reason === \"refusal\" && response.stop_details) {\n console.log(`Category: ${response.stop_details.category}`); // e.g. \"cyber\", \"bio\", \"reasoning_extraction\", \"frontier_llm\", or null — see docs for the full set\n console.log(`Explanation: ${response.stop_details.explanation}`);\n}\n```\n\n### Refusal Fallbacks (Claude Fable 5) — opt in by default\n\nFallbacks are **opt-in**: without them a refused request simply stops. Include the server-side `fallbacks` parameter in `claude-fable-5` code by default — on a policy decline the API re-runs the same request on the fallback model inside the same call. A decline before any output isn't billed (a mid-stream decline bills the streamed partial); the rescue bills at the fallback model's own rates, with cache repricing applied automatically.\n\n```typescript\nconst response = await client.beta.messages.create({\n model: \"claude-fable-5\",\n max_tokens: 16000,\n betas: [\"server-side-fallback-2026-06-01\"],\n fallbacks: [{ model: \"claude-opus-4-8\" }],\n messages: [{ role: \"user\", content: \"...\" }],\n});\n\n// Switch points: one fallback block per model that ran and declined this turn\nfor (const block of response.content) {\n if (block.type === \"fallback\") {\n console.log(`${block.from.model} declined; ${block.to.model} continued`);\n }\n}\n\n// Served-by signal — covers sticky turns, which carry no fallback block.\n// Pair with stop_reason: the fallback model can itself refuse.\nconst fallbackRan = (response.usage.iterations ?? []).some(\n (entry) => entry.type === \"fallback_message\",\n);\nif (fallbackRan && response.stop_reason !== \"refusal\") {\n console.log(`Served by ${response.model}`);\n}\n```\n\nA `stop_reason: \"refusal\"` on the final response means the whole chain refused. The header must be exactly `server-side-fallback-2026-06-01`; the parameter is rejected on the Batches API and unavailable on Amazon Bedrock, Vertex AI, and Microsoft Foundry — register the client-side `betaRefusalFallbackMiddleware` on the client there instead.

Use Prompt Caching for Repeated Context\n\n```typescript\n// Automatic caching (simplest — caches the last cacheable block)\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n cache_control: { type: \"ephemeral\" },\n system: largeDocumentText, // e.g., 50KB of context\n messages: [{ role: \"user\", content: \"Summarize the key points\" }],\n});\n\n// First request: full cost\n// Subsequent requests: ~90% cheaper for cached portion\n```\n\n### 2. Use Token Counting Before Requests\n\n```typescript\nconst countResponse = await client.messages.countTokens({\n model: \"claude-opus-4-8\",\n messages: messages,\n system: system,\n});\n\nconst estimatedInputCost = countResponse.input_tokens * 0.000005; // $5/1M tokens\nconsole.log(`Estimated input cost: $${estimatedInputCost.toFixed(4)}`);\n```\n</doc>\n\n<doc path=\"typescript/claude-api/batches.md\">\n# Message Batches API — TypeScript\n\nThe Batches API (`POST /v1/messages/batches`) processes Messages API requests asynchronously at 50% of standard prices.\n\n## Key Facts\n\n- Up to 100,000 requests or 256 MB per batch\n- Most batches complete within 1 hour; maximum 24 hours\n- Results available for 29 days after creation\n- 50% cost reduction on all token usage\n- All Messages API features supported (vision, tools, caching, etc.)\n\n---\n\n## Create a Batch\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\nconst client = new Anthropic();\n\nconst messageBatch = await client.messages.batches.create({\n requests: [\n {\n custom_id: \"request-1\",\n params: {\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [\n { role: \"user\", content: \"Summarize climate change impacts\" },\n ],\n },\n },\n {\n custom_id: \"request-2\",\n params: {\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [\n { role: \"user\", content: \"Explain quantum computing basics\" },\n ],\n },\n },\n ],\n});\n\nconsole.log(`Batch ID: ${messageBatch.id}`);\nconsole.log(`Status: ${messageBatch.processing_status}`);\n```\n\n---\n\n## Poll for Completion\n\n```typescript\nlet batch;\nwhile (true) {\n batch = await client.messages.batches.retrieve(messageBatch.id);\n if (batch.processing_status === \"ended\") break;\n console.log(\n `Status: ${batch.processing_status}, processing: ${batch.request_counts.processing}`,\n );\n await new Promise((resolve) => setTimeout(resolve, 60_000));\n}\n\nconsole.log(\"Batch complete!\");\nconsole.log(`Succeeded: ${batch.request_counts.succeeded}`);\nconsole.log(`Errored: ${batch.request_counts.errored}`);\n```\n\n---\n\n## Retrieve Results\n\n```typescript\nfor await (const result of await client.messages.batches.results(\n messageBatch.id,\n)) {\n switch (result.result.type) {\n case \"succeeded\":\n console.log(\n `[${result.custom_id}] ${result.result.message.content[0].text.slice(0, 100)}`,\n );\n break;\n case \"errored\":\n if (result.result.error.type === \"invalid_request\") {\n console.log(`[${result.custom_id}] Validation error - fix and retry`);\n } else {\n console.log(`[${result.custom_id}] Server error - safe to retry`);\n }\n break;\n case \"expired\":\n console.log(`[${result.custom_id}] Expired - resubmit`);\n break;\n }\n}\n```\n\n---\n\n## Cancel a Batch\n\n```typescript\nconst cancelled = await client.messages.batches.cancel(messageBatch.id);\nconsole.log(`Status: ${cancelled.processing_status}`); // \"canceling\"\n```\n</doc>\n\n<doc path=\"typescript/claude-api/files-api.md\">\n# Files API — TypeScript\n\nThe Files API uploads files for use in Messages API requests.

The outer loop iterates over tool runner iterations (messages), the inner loop processes stream events:\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\nimport { betaZodTool } from \"@anthropic-ai/sdk/helpers/beta/zod\";\nimport { z } from \"zod\";\n\nconst client = new Anthropic();\n\nconst getWeather = betaZodTool({\n name: \"get_weather\",\n description: \"Get current weather for a location\",\n inputSchema: z.object({\n location: z.string().describe(\"City and state, e.g., San Francisco, CA\"),\n }),\n run: async ({ location }) => `72°F and sunny in ${location}`,\n});\n\nconst runner = client.beta.messages.toolRunner({\n model: \"claude-opus-4-8\",\n max_tokens: 64000,\n tools: [getWeather],\n messages: [\n { role: \"user\", content: \"What's the weather in Paris and London?\" },\n ],\n stream: true,\n});\n\n// Outer loop: each tool runner iteration\nfor await (const messageStream of runner) {\n // Inner loop: stream events for this iteration\n for await (const event of messageStream) {\n switch (event.type) {\n case \"content_block_delta\":\n switch (event.delta.type) {\n case \"text_delta\":\n process.stdout.write(event.delta.text);\n break;\n case \"input_json_delta\":\n // Tool input being streamed\n break;\n }\n break;\n }\n }\n}\n```\n\n---\n\n## Getting the Final Message\n\n```typescript\nconst stream = client.messages.stream({\n model: \"claude-opus-4-8\",\n max_tokens: 64000,\n messages: [{ role: \"user\", content: \"Hello\" }],\n});\n\nfor await (const event of stream) {\n // Process events...\n}\n\nconst finalMessage = await stream.finalMessage();\nconsole.log(`Tokens used: ${finalMessage.usage.output_tokens}`);\n```\n\n---\n\n## Stream Event Types\n\n| Event Type | Description | When it fires |\n| --------------------- | --------------------------- | --------------------------------- |\n| `message_start` | Contains message metadata | Once at the beginning |\n| `content_block_start` | New content block beginning | When a text/tool_use block starts |\n| `content_block_delta` | Incremental content update | For each token/chunk |\n| `content_block_stop` | Content block complete | When a block finishes |\n| `message_delta` | Message-level updates | Contains `stop_reason`, usage |\n| `message_stop` | Message complete | Once at the end |\n\n## Best Practices\n\n1. **Always flush output** — Use `process.stdout.write()` for immediate display\n2. **Handle partial responses** — If the stream is interrupted, you may have incomplete content\n3. **Track token usage** — The `message_delta` event contains usage information\n4. **Use `finalMessage()`** — Get the complete `Anthropic.Message` object even when streaming. Don't wrap `.on()` events in `new Promise()` — `finalMessage()` handles all completion/error/abort states internally\n5. **Buffer for web UIs** — Consider buffering a few tokens before rendering to avoid excessive DOM updates\n6. **Use `stream.on(\"text\", ...)` for deltas** — The `text` event provides just the delta string, simpler than manually filtering `content_block_delta` events\n7. **For agentic loops with streaming** — See the [Streaming Manual Loop](./tool-use.md#streaming-manual-loop) section in tool-use.md for combining `stream()` + `finalMessage()` with a tool-use loop\n\n## Raw SSE Format\n\nIf using raw HTTP (not SDKs), the stream returns Server-Sent Events:\n\n```\nevent: message_start\ndata: {\"type\":\"message_start\",\"message\":{\"id\":\"msg_...\",\"type\":\"message\",...}}\n\nevent: content_block_start\ndata: {\"type\":\"content_block_start\",\"index\":0,\"content_block\":{\"type\":\"text\",\"text\":\"\"}}\n\nevent: content_block_delta\ndata: {\"type\":\"content_block_delta\",\"index\":0,\"delta\":{\"type\":\"text_delta\",\"text\":\"Hello\"}}\n\nevent: content_block_stop\ndata: {\"type\":\"content_block_stop\",\"index\":0}\n\nevent: message_delta\ndata: {\"type\":\"message_delta\",\"delta\":{\"stop_reason\":\"end_turn\"},\"usage\":{\"output_tokens\":12}}\n\nevent: message_stop\ndata: {\"type\":\"message_stop\"}\n```\n</doc>\n\n<doc path=\"typescript/claude-api/tool-use.md\">\n# Tool Use — TypeScript\n\nFor conceptual overview (tool definitions, tool choice, tips), see [shared/tool-use-concepts.md](../../shared/tool-use-concepts.md).\n\n## Tool Runner (Recommended)\n\n**Beta:** The tool runner is in beta in the TypeScript SDK.\n\nUse `betaZodTool` with Zod schemas to define tools with a `run` function, then pass them to `client.beta.messages.toolRunner()`:\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\nimport { betaZodTool } from \"@anthropic-ai/sdk/helpers/beta/zod\";\nimport { z } from \"zod\";\n\nconst client = new Anthropic();\n\nconst getWeather = betaZodTool({\n name: \"get_weather\",\n description: \"Get current weather for a location\",\n inputSchema: z.object({\n location: z.string().describe(\"City and state, e.g., San Francisco, CA\"),\n unit: z.enum([\"celsius\", \"fahrenheit\"]).optional(),\n }),\n run: async (input) => {\n // Your implementation here\n return `72°F and sunny in ${input.location}`;\n },\n});\n\n// The tool runner handles the agentic loop and returns the final message\nconst finalMessage = await client.beta.messages.toolRunner({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: [getWeather],\n messages: [{ role: \"user\", content: \"What's the weather in Paris?\" }],\n});\n\nconsole.log(finalMessage.content);\n```\n\n**Key benefits of the tool runner:**\n\n- No manual loop — the SDK handles calling tools and feeding results back\n- Type-safe tool inputs via Zod schemas\n- Tool schemas are generated automatically from Zod definitions\n- Iteration stops automatically when Claude has no more tool calls\n\n---\n\n## Manual Agentic Loop\n\nUse this when you need fine-grained control (custom logging, conditional tool execution, streaming individual iterations, human-in-the-loop approval):\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\nconst client = new Anthropic();\nconst tools: Anthropic.Tool[] = [...]; // Your tool definitions\nlet messages: Anthropic.MessageParam[] = [{ role: \"user\", content: userInput }];\n\nwhile (true) {\n const response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: tools,\n messages: messages,\n });\n\n if (response.stop_reason === \"end_turn\") break;\n\n // Server-side tool hit iteration limit; append assistant turn and re-send to continue\n if (response.stop_reason === \"pause_turn\") {\n messages.push({ role: \"assistant\", content: response.content });\n continue;\n }\n\n const toolUseBlocks = response.content.filter(\n (b): b is Anthropic.ToolUseBlock => b.type === \"tool_use\",\n );\n\n messages.push({ role: \"assistant\", content: response.content });\n\n const toolResults: Anthropic.ToolResultBlockParam[] = [];\n for (const tool of toolUseBlocks) {\n const result = await executeTool(tool.name, tool.input);\n toolResults.push({\n type: \"tool_result\",\n tool_use_id: tool.id,\n content: result,\n });\n }\n\n messages.push({ role: \"user\", content: toolResults });\n}\n```\n\n### Streaming Manual Loop\n\nUse `client.messages.stream()` + `finalMessage()` instead of `.create()` when you need streaming within a manual loop. Text deltas are streamed on each iteration; `finalMessage()` collects the complete `Message` so you can inspect `stop_reason` and extract tool-use blocks:\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\nconst client = new Anthropic();\nconst tools: Anthropic.Tool[] = [...];\nlet messages: Anthropic.MessageParam[] = [{ role: \"user\", content: userInput }];\n\nwhile (true) {\n const stream = client.messages.stream({\n model: \"claude-opus-4-8\",\n max_tokens: 64000,\n tools,\n messages,\n });\n\n // Stream text deltas on each iteration\n stream.on(\"text\", (delta) => {\n process.stdout.write(delta);\n });\n\n // finalMessage() resolves with the complete Message — no need to\n // manually wire up .on(\"message\") / .on(\"error\") / .on(\"abort\")\n const message = await stream.finalMessage();\n\n if (message.stop_reason === \"end_turn\") break;\n\n // Server-side tool hit iteration limit; append assistant turn and re-send to continue\n if (message.stop_reason === \"pause_turn\") {\n messages.push({ role: \"assistant\", content: message.content });\n continue;\n }\n\n const toolUseBlocks = message.content.filter(\n (b): b is Anthropic.ToolUseBlock => b.type === \"tool_use\",\n );\n\n messages.push({ role: \"assistant\", content: message.content });\n\n const toolResults: Anthropic.ToolResultBlockParam[] = [];\n for (const tool of toolUseBlocks) {\n const result = await executeTool(tool.name, tool.input);\n toolResults.push({\n type: \"tool_result\",\n tool_use_id: tool.id,\n content: result,\n });\n }\n\n messages.push({ role: \"user\", content: toolResults });\n}\n```\n\n> **Important:** Don't wrap `.on()` events in `new Promise()` to collect the final message — use `stream.finalMessage()` instead. The SDK handles all error/abort/completion states internally.\n\n> **Error handling in the loop:** Use the SDK's typed exceptions (e.g., `Anthropic.RateLimitError`, `Anthropic.APIError`) — see [Error Handling](./README.md#error-handling) for examples. Don't check error messages with string matching.\n\n> **SDK types:** Use `Anthropic.MessageParam`, `Anthropic.Tool`, `Anthropic.ToolUseBlock`, `Anthropic.ToolResultBlockParam`, `Anthropic.Message`, etc. for all API-related data structures. Don't redefine equivalent interfaces.\n\n---\n\n## Handling Tool Results\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: tools,\n messages: [{ role: \"user\", content: \"What's the weather in Paris?\" }],\n});\n\nfor (const block of response.content) {\n if (block.type === \"tool_use\") {\n const result = await executeTool(block.name, block.input);\n\n const followup = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: tools,\n messages: [\n { role: \"user\", content: \"What's the weather in Paris?\" },\n { role: \"assistant\", content: response.content },\n {\n role: \"user\",\n content: [\n { type: \"tool_result\", tool_use_id: block.id, content: result },\n ],\n },\n ],\n });\n }\n}\n```\n\n---\n\n## Tool Choice\n\n```typescript\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: tools,\n tool_choice: { type: \"tool\", name: \"get_weather\" },\n messages: [{ role: \"user\", content: \"What's the weather in Paris?\" }],\n});\n```\n\n---\n\n## Anthropic-Defined Tools\n\nVersion-suffixed `type` literals; `name` is fixed per interface. Web search and code execution are server-executed; bash and text editor are client-executed (you handle the `tool_use` locally — see `shared/tool-use-concepts.md`). Pass plain object literals — the `ToolUnion` type is satisfied structurally. **The `name`/`type` pair must match the interface**: mixing `str_replace_based_edit_tool` (20250728 name) with `text_editor_20250124` (which expects `str_replace_editor`) is a TS2322.\n\n**Don't type-annotate as `Tool[]`** — `Tool` is just the custom-tool variant. Let structural typing infer from the `tools` param, or annotate as `Anthropic.Messages.ToolUnion[]` if you must:\n\n```typescript\n// ✓ let inference work — no annotation\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n tools: [\n { type: \"text_editor_20250728\", name: \"str_replace_based_edit_tool\" },\n { type: \"bash_20250124\", name: \"bash\" },\n { type: \"web_search_20260209\", name: \"web_search\" },\n { type: \"code_execution_20260120\", name: \"code_execution\" },\n ],\n messages: [{ role: \"user\", content: \"...\" }],\n});\n\n// ✗ this is a TS2352 — Tool is the CUSTOM tool variant only\n// const tools: Anthropic.Tool[] = [{ type: \"text_editor_20250728\", ... }]\n```\n\n| Interface | `name` | `type` |\n|---|---|---|\n| `ToolTextEditor20250124` | `str_replace_editor` | `text_editor_20250124` |\n| `ToolTextEditor20250429` | `str_replace_based_edit_tool` | `text_editor_20250429` |\n| `ToolTextEditor20250728` | `str_replace_based_edit_tool` | `text_editor_20250728` |\n| `ToolBash20250124` | `bash` | `bash_20250124` |\n| `WebSearchTool20260209` | `web_search` | `web_search_20260209` |\n| `WebFetchTool20260209` | `web_fetch` | `web_fetch_20260209` |\n| `CodeExecutionTool20260120` | `code_execution` | `code_execution_20260120` |\n\n**Don't mix beta and non-beta types**: if you call `client.beta.messages.create()`, the response `content` is `BetaContentBlock[]` — you cannot pass that to a non-beta `ContentBlockParam[]` without narrowing each element.\n\n---\n\n\n## Code Execution\n\n### Basic Usage\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\nconst client = new Anthropic();\n\nconst response = await client.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n messages: [\n {\n role: \"user\",\n content:\n \"Calculate the mean and standard deviation of [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]\",\n },\n ],\n tools: [{ type: \"code_execution_20260120\", name: \"code_execution\" }],\n});\n```\n\n### Reading Local Files (ESM note)\n\n`__dirname` doesn't exist in ES modules.

Both beta headers are required. Outputs land as files in the response content — download by file ID via the Files API.\n\n```typescript\nconst response = await client.beta.messages.create({\n model: \"claude-opus-4-8\",\n max_tokens: 16000,\n container: {\n skills: [{ type: \"anthropic\", skill_id: \"pptx\", version: \"latest\" }],\n },\n tools: [{ type: \"code_execution_20260521\", name: \"code_execution\" }],\n betas: [\"code-execution-2025-08-25\", \"skills-2025-10-02\"],\n messages: [{ role: \"user\", content: \"Create a 3-slide deck about X.\" }],\n});\n// Find the file_id in response.content, then:\n// await client.beta.files.download(fileId)\n```\n</doc>\n\n<doc path=\"typescript/managed-agents/README.md\">\n# Managed Agents — TypeScript\n\n> **Bindings not shown here:** This README covers the most common managed-agents flows for TypeScript. If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the TypeScript SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.\n\n> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.create` and pass it to every subsequent `sessions.create`; do not call `agents.create` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.\n\n## Installation\n\n```bash\nnpm install @anthropic-ai/sdk\n```\n\n## Client Initialization\n\n```typescript\nimport Anthropic from \"@anthropic-ai/sdk\";\n\n// Default — resolves credentials from the environment:\n// ANTHROPIC_API_KEY, or ANTHROPIC_AUTH_TOKEN, or an `ant auth login` profile.\n// Prefer this for local dev; don't hardcode a key.\nconst client = new Anthropic();\n\n// Explicit API key (only when you must inject a specific key)\nconst client = new Anthropic({ apiKey: \"your-api-key\" });\n```\n\n---\n\n## Create an Environment\n\n```typescript\nconst environment = await client.beta.environments.create(\n {\n name: \"my-dev-env\",\n config: {\n type: \"cloud\",\n networking: { type: \"unrestricted\" },\n },\n },\n);\nconsole.log(environment.id); // env_...\n```\n\n---\n\n## Create an Agent (required first step)\n\n> ⚠️ **There is no inline agent config.** `model`/`system`/`tools` live on the agent object, not the session. Always start with `agents.create()` — the session only takes `agent: { type: \"agent\", id: agent.id }`.\n\n### Minimal\n\n```typescript\n// 1. Create the agent (reusable, versioned)\nconst agent = await client.beta.agents.create(\n {\n name: \"Coding Assistant\",\n model: \"claude-opus-4-8\",\n tools: [{ type: \"agent_toolset_20260401\", default_config: { enabled: true } }],\n },\n);\n\n// 2. Start a session\nconst session = await client.beta.sessions.create(\n {\n agent: { type: \"agent\", id: agent.id, version: agent.version },\n environment_id: environment.id,\n },\n);\nconsole.log(session.id, session.status);\nconsole.log(`Trace: https://platform.claude.com/workspaces/default/sessions/${session.id}`);\n```\n\n### With system prompt and custom tools\n\n```typescript\nconst agent = await client.beta.agents.create(\n {\n name: \"Code Reviewer\",\n model: \"claude-opus-4-8\",\n system: \"You are a senior code reviewer.\",\n tools: [\n { type: \"agent_toolset_20260401\", default_config: { enabled: true } },\n {\n type: \"custom\",\n name: \"run_tests\",\n description: \"Run the test suite\",\n input_schema: {\n type: \"object\",\n properties: {\n test_path: { type: \"string\", description: \"Path to test file\" },\n },\n required: [\"test_path\"],\n },\n },\n ],\n },\n);\n\nconst session = await client.beta.sessions.create(\n {\n agent: { type: \"agent\", id: agent.id, version: agent.version },\n environment_id: environment.id,\n title: \"Code review session\",\n resources: [\n {\n type: \"github_repository\",\n url: \"https://github.com/owner/repo\",\n mount_path: \"/workspace/repo\",\n authorization_token: process.env.GITHUB_TOKEN,\n branch: \"main\",\n },\n ],\n },\n);\n```\n\n---\n\n## Send a User Message\n\n```typescript\nawait client.beta.sessions.events.send(\n session.id,\n {\n events: [\n {\n type: \"user.message\",\n content: [{ type: \"text\", text: \"Review the auth module\" }],\n },\n ],\n },\n);\n```\n\n> 💡 **Stream-first:** Open the stream *before* (or concurrently with) sending the message. The stream only delivers events that occur after it opens — stream-after-send means early events arrive buffered in one batch. See [Steering Patterns](../../shared/managed-agents-events.md#steering-patterns).\n\n---\n\n## Stream Events (SSE)\n\n```typescript\n// Stream-first: open stream and send concurrently\nconst [events] = await Promise.all([\n collectStream(session.id),\n client.beta.sessions.events.send(\n session.id,\n { events: [{ type: \"user.message\", content: [{ type: \"text\", text: \"...\" }] }] },\n ),\n]);\n\n// Standalone stream iteration:\nconst stream = await client.beta.sessions.events.stream(\n session.id,\n);\n\nfor await (const event of stream) {\n switch (event.type) {\n case \"agent.message\":\n for (const block of event.content) {\n if (block.type === \"text\") {\n process.stdout.write(block.text);\n }\n }\n break;\n case \"agent.custom_tool_use\":\n // Custom tool invocation — session is now idle\n console.log(`\\nCustom tool call: ${event.name}`);\n console.log(`Input: ${JSON.stringify(event.input)}`);\n break;\n case \"session.status_idle\":\n console.log(\"\\n--- Agent idle ---\");\n break;\n case \"session.status_terminated\":\n console.log(\"\\n--- Session terminated ---\");\n break;\n }\n}\n```\n\n---\n\n## Provide Custom Tool Result\n\n```typescript\nawait client.beta.sessions.events.send(\n session.id,\n {\n events: [\n {\n type: \"user.custom_tool_result\",\n custom_tool_use_id: \"sevt_abc123\",\n content: [{ type: \"text\", text: \"All 42 tests passed.\" }],\n },\n ],\n },\n);\n```\n\n---\n\n## Poll Events\n\n```typescript\nconst events = await client.beta.sessions.events.list(\n session.id,\n);\nfor (const event of events.data) {\n console.log(`${event.type}: ${event.id}`);\n}\n```\n\n---\n\n## Full Streaming Loop with Custom Tools\n\n```typescript\nfunction runCustomTool(toolName: string, toolInput: unknown): string {\n if (toolName === \"run_tests\") {\n // Your tool implementation here\n return \"All tests passed.\";\n }\n return `Unknown tool: ${toolName}`;\n}\n\nasync function runSession(client: Anthropic, sessionId: string) {\n while (true) {\n const stream = await client.beta.sessions.events.stream(\n sessionId,\n );\n\n const toolCalls: Anthropic.Beta.Sessions.BetaManagedAgentsAgentCustomToolUseEvent[] = [];\n\n for await (const event of stream) {\n if (event.type === \"agent.message\") {\n for (const block of event.content) {\n if (block.type === \"text\") {\n process.stdout.write(block.text);\n }\n }\n } else if (event.type === \"agent.custom_tool_use\") {\n toolCalls.push(event);\n } else if (event.type === \"session.status_idle\") {\n break;\n } else if (event.type === \"session.status_terminated\") {\n return;\n }\n }\n\n if (toolCalls.length === 0) break;\n\n // Process custom tool calls\n const results = toolCalls.map((call) => ({\n type: \"user.custom_tool_result\" as const,\n custom_tool_use_id: call.id,\n content: [{ type: \"text\" as const, text: runCustomTool(call.name, call.input) }],\n }));\n\n await client.beta.sessions.events.send(\n sessionId,\n { events: results },\n );\n }\n}\n```\n\n---\n\n## Upload a File\n\n```typescript\nimport fs from \"fs\";\n\nconst file = await client.beta.files.upload({\n file: fs.createReadStream(\"data.csv\"),\n purpose: \"agent\",\n});\n\n// Use in a session\nconst session = await client.beta.sessions.create(\n {\n agent: { type: \"agent\", id: agent.id, version: agent.version },\n environment_id: environment.id,\n resources: [{ type: \"file\", file_id: file.id, mount_path: \"/workspace/data.csv\" }],\n },\n);\n```\n\n---\n\n## List and Download Session Files\n\nList files the agent wrote to `/mnt/session/outputs/` during a session, then download them.\n\n```typescript\nimport fs from \"fs\";\n\n// List files associated with a session\nconst files = await client.beta.files.list({\n scope_id: session.id,\n betas: [\"managed-agents-2026-04-01\"],\n});\nfor (const f of files.data) {\n console.log(f.filename, f.size_bytes);\n\n // Download and save to disk\n const resp = await client.beta.files.download(f.id);\n const buffer = Buffer.from(await resp.arrayBuffer());\n fs.writeFileSync(f.filename, buffer);\n}\n```\n\n> 💡 There's a brief indexing lag (~1–3s) between `session.status_idle` and output files appearing in `files.list`. Retry once or twice if the list is empty.\n\n---\n\n## Session Management\n\n```typescript\n// Get session details\nconst session = await client.beta.sessions.retrieve(\"sesn_011CZxAbc123Def456\");\nconsole.log(session.status, session.usage);\n\n// List sessions\nconst sessions = await client.beta.sessions.list();\n\n// Delete a session\nawait client.beta.sessions.delete(\"sesn_011CZxAbc123Def456\");\n\n// Archive a session\nawait client.beta.sessions.archive(\"sesn_011CZxAbc123Def456\");\n```\n\n---\n\n## MCP Server Integration\n\n```typescript\n// Agent declares MCP server (no auth here — auth goes in a vault)\nconst agent = await client.beta.agents.create({\n name: \"MCP Agent\",\n model: \"claude-opus-4-8\",\n mcp_servers: [\n { type: \"url\", name: \"my-tools\", url: \"https://my-mcp-server.example.com/sse\" },\n ],\n tools: [\n { type: \"agent_toolset_20260401\", default_config: { enabled: true } },\n { type: \"mcp_toolset\", mcp_server_name: \"my-tools\" },\n ],\n});\n\n// Session attaches vault(s) containing credentials for those MCP server URLs\nconst session = await client.beta.sessions.create({\n agent: agent.id,\n environment_id: environment.id,\n vault_ids: [vault.id],\n});\n```\n\nSee `shared/managed-agents-tools.md` §Vaults for creating vaults and adding credentials.\n</doc>\n\n## When to Use WebFetch\n\nUse WebFetch to get the latest documentation when:\n\n- User asks for \"latest\" or \"current\" information\n- Cached data seems incorrect\n- User asks about features not covered here\n\nLive documentation URLs are in `shared/live-sources.md`.\n\n## Common Pitfalls\n\n- **No `ANTHROPIC_API_KEY` ≠ no credentials.** Don't bail or ask the user for a key just because the env var is unset — run `ant auth status` first. After `ant auth login`, a bare `Anthropic()` client and `ant …` work with no env var; for raw curl, use `Authorization: Bearer $(ant auth print-credentials --access-token)` plus header `anthropic-beta: oauth-2025-04-20`. See the Authentication quick reference above and `shared/anthropic-cli.md`.\n- Don't truncate inputs when passing files or content to the API. If the content is too long to fit in the context window, notify the user and discuss options (chunking, summarization, etc.) rather than silently truncating.\n- **Fable 5 / Sonnet 5 / Opus 4.8 / 4.7 thinking:** Adaptive only. `thinking: {type: \"enabled\", budget_tokens: N}` returns 400 — `budget_tokens` is fully removed (along with `temperature`, `top_p`, `top_k`). Use `thinking: {type: \"adaptive\"}`. Opus 4.8 inherits this surface from 4.7 with no new breaking changes; Fable 5 adds one — an explicit `thinking: {type: \"disabled\"}` returns a 400 (accepted on Sonnet 5 / 4.7 / 4.8); omit the param instead.\n- **Opus 4.6 / Sonnet 4.6 thinking:** Use `thinking: {type: \"adaptive\"}` — do NOT use `budget_tokens` for new 4.6 code (deprecated on both Opus 4.6 and Sonnet 4.6; for gradual migration of existing code, see the transitional escape hatch in `shared/model-migration.md` — note this carve-out does not apply to Fable 5, Opus 4.7 or 4.8). For older models, `budget_tokens` must be less than `max_tokens` (minimum 1024). This will throw an error if you get it wrong.\n- **Prefill removed (Fable 5 and the 4.6/4.7/4.8 family):** Assistant message prefills (last-assistant-turn prefills) return a 400 error on Fable 5, Opus 4.6, Opus 4.7, Opus 4.8, and Sonnet 4.6. Use structured outputs (`output_config.format`) or system prompt instructions to control response format instead. (One exception: the fallback-credit prefill claim — when redeeming a credit with `fallback_has_prefill_claim: true`, the server accepts the echoed assistant message; see the migration guide's refusal section.)\n- **Fable 5 `refusal` stop reason:** Safety classifiers may decline a request — a successful HTTP 200 with `stop_reason: \"refusal\"` (pre-output: empty `content`, nothing billed; mid-stream: partial output billed — discard it). Check `stop_reason` before reading `response.content[0]`, or you'll hit index errors on refused requests. To retry on another model, replay the history as-is — other models drop the refused model's thinking blocks from the prompt, unbilled; no stripping needed (and a fallback-credit redemption must echo the refused body exactly anyway, thinking blocks included). Fallbacks are **opt-in** — new `claude-fable-5` code should include the server-side `fallbacks` parameter by default so a refusal doesn't fail the request outright; see the Claude Fable 5 section above.\n- **Fable 5 tokenizer:** Same tokenizer as Opus 4.8 — token counts are roughly unchanged when migrating from Opus 4.7/4.8. Coming from Opus 4.6, Sonnet, Haiku, or older, token counts differ (the Opus 4.7 tokenizer uses ~1×–1.35× as many tokens) — re-measure by calling `count_tokens` once with each model and comparing `input_tokens`.\n- **Confirm migration scope before editing:** When a user asks to migrate code to a newer Claude model without naming a specific file, directory, or file list, **ask which scope to apply first** — the entire working directory, a specific subdirectory, or a specific set of files. Do not start editing until the user confirms. Imperative phrasings like \"migrate my codebase\", \"move my project to X\", \"upgrade to Sonnet 4.6\", or bare \"migrate to Opus 4.8\" are **still ambiguous** — they tell you what to do but not where, so ask. Proceed without asking only when the prompt names an exact file, a specific directory, or an explicit file list (\"migrate `app.py`\", \"migrate everything under `services/`\", \"update `a.py` and `b.py`\"). See `shared/model-migration.md` Step 0.\n- **`max_tokens` defaults:** Don't lowball `max_tokens` — hitting the cap truncates output mid-thought and requires a retry. For non-streaming requests, default to `~16000` (keeps responses under SDK HTTP timeouts). For streaming requests, default to `~64000` (timeouts aren't a concern, so give the model room). Only go lower when you have a hard reason: classification (`~256`), cost caps, deliberately short outputs, or **`max_tokens: 0`** for cache pre-warming (see `shared/prompt-caching.md` → Pre-warming).\n- **128K output tokens:** Fable 5, Opus 4.6, Opus 4.7, Opus 4.8, Sonnet 5, and Sonnet 4.6 support up to 128K `max_tokens`, but the SDKs require streaming for values that large to avoid HTTP timeouts. Use `.stream()` with `.get_final_message()` / `.finalMessage()`.\n- **Tool call JSON parsing (Fable 5 and the 4.6/4.7/4.8 family):** Fable 5, Opus 4.6, Opus 4.7, Opus 4.8, and Sonnet 4.6 may produce different JSON string escaping in tool call `input` fields (e.g., Unicode or forward-slash escaping). Always parse tool inputs with `json.loads()` / `JSON.parse()` — never do raw string matching on the serialized input.\n- **Structured outputs (all models):** Use `output_config: {format: {...}}` instead of the deprecated `output_format` parameter on `messages.create()`. This is a general API change, not 4.6-specific.\n- **Don't reimplement SDK functionality:** The SDK provides high-level helpers — use them instead of building from scratch. Specifically: use `stream.finalMessage()` instead of wrapping `.on()` events in `new Promise()`; use typed exception classes (`Anthropic.RateLimitError`, etc.) instead of string-matching error messages; use SDK types (`Anthropic.MessageParam`, `Anthropic.Tool`, `Anthropic.Message`, etc.) instead of redefining equivalent interfaces.\n- **Error handling — catch a chain, not one broad class.** A single `except APIStatusError` / `catch (AnthropicServiceException)` / `rescue APIError` loses the distinction between retryable (429, ≥500, network) and non-retryable (400/404) failures. Write a most-specific-first chain — e.g. `NotFoundError` → `RateLimitError` → `APIStatusError` → `APIConnectionError` (or the Go equivalent: `errors.As` into `*anthropic.Error` then `switch apierr.StatusCode { case 404: …; case 429: …; default: … }`). Per-language class names and namespaces are in `shared/error-codes.md`.\n- **Don't research SDK types — write first.** If a type name isn't shown in the documentation included in this skill, write the code file from the namespace/package tables in the language-specific doc and let the compiler's error point you to the right name. Do not spend turns on WebFetch, SDK-repo clones, or compiling-and-running a separate reflection program to discover type names before writing — produce the source file first, then fix what the compiler reports. A quick `strings` / `jar tf` / `javap` against the installed SDK is acceptable for locating names (it returns in seconds), but don't escalate beyond that. A file with a wrong type name is recoverable; a session spent on discovery with no file written is not.\n- **Bash and text editor tools are Anthropic-defined, schema-less.** Declare `{\"type\": \"bash_20250124\", \"name\": \"bash\"}` / `{\"type\": \"text_editor_20250728\", \"name\": \"str_replace_based_edit_tool\"}` — no `input_schema`. A custom tool with your own schema named `\"bash\"` is a different tool. Handler paths and security checks are in `shared/tool-use-concepts.md` § Client-Side Tools.\n- **Advisor tool model pairing.** The advisor tool's `model` must be at least as capable as the request's top-level `model` — e.g. executor `claude-sonnet-5` → advisor `claude-opus-4-8` or `claude-opus-4-7`. An invalid pair returns 400. Pairing table in `shared/tool-use-concepts.md` § Advisor. Availability: `shared/platform-availability.md`.\n- **Agent Skills ≠ Managed Agents.** To have Claude generate a `.pptx`/`.xlsx`/etc. via Agent Skills, call `client.beta.messages.create` with `container={\"skills\": [...]}`, the `code_execution_20260521` tool, and both `code-execution-2025-08-25` + `skills-2025-10-02` betas. Do not use `client.beta.agents` / `sessions` / `environments` here — those are the Managed Agents surface, not Agent Skills.\n- **MCP connector needs both halves.** `mcp_servers=[{type:\"url\", url, name}]` alone is rejected as a validation error — also add `tools=[{type:\"mcp_toolset\", mcp_server_name:<same name>}]` with beta `mcp-client-2025-11-20`. Availability: `shared/platform-availability.md`.\n- **Context editing ≠ compaction.** Context editing *clears* tool results and thinking blocks; compaction *summarizes* history. For context editing, use `context_management.edits` with type `clear_tool_uses_20250919` (or `clear_thinking_20251015`) on `client.beta.messages.*` with beta `context-management-2025-06-27` — not the `compact_20260112` type or `compact-2026-01-12` beta, which are compaction.\n- **`inference_geo` is a direct top-level request parameter** — `client.messages.create(..., inference_geo=\"us\")` / `.inferenceGeo(\"us\")`. Do not put it in `extra_body` / `putAdditionalBodyProperty`. Supported on Opus 4.6 / Sonnet 4.6 and later; availability: `shared/platform-availability.md`. `response.usage.inference_geo` reports where inference ran.\n- **Fine-grained tool streaming is not a beta feature.** Set `eager_input_streaming: true` on the tool definition and call the regular `client.messages.stream(...)`. There is no beta header and no `client.beta.*` path.\n- **Cache diagnostics is beta.** Use `client.beta.messages.*` with beta `cache-diagnosis-2026-04-07`. Pass `diagnostics: {previous_message_id: null}` on the first turn and `diagnostics: {previous_message_id: <previous response id>}` on subsequent turns; the result is on `response.diagnostics`. Availability: `shared/platform-availability.md`.\n- **Memory tool type is `memory_20250818`.** Declare `{\"type\": \"memory_20250818\", \"name\": \"memory\"}`. Go uses the beta-namespace type `{OfMemoryTool20250818: &anthropic.BetaMemoryTool20250818Param{}}` on `client.Beta.Messages.New`; Python/TypeScript/Ruby/PHP/C# use the non-beta `client.messages.create`; Java has both a non-beta `MemoryTool20250818` and a beta tool-runner path. Python/TypeScript provide `BetaAbstractMemoryTool` / `betaMemoryTool` helpers for implementing the backend.\n- **Use a model the feature actually supports.** Some features are restricted to specific model tiers — fast mode is Opus 4.8 / 4.7 only, task budgets are Fable 5 / Sonnet 5 / Opus 4.8 / 4.7 only, and the advisor tool requires a valid executor↔advisor pair. If the user's prompt names a model that the feature doesn't support, use a supported model instead and note the substitution in the output.\n- **Bedrock / Foundry: use the platform client class.** For Bedrock use the `…BedrockMantle…` client (e.g. Python `AnthropicBedrockMantle`, Java `BedrockMantleBackend`) with `anthropic.`-prefixed model IDs; `AnthropicBedrock`/`BedrockBackend` without `Mantle` is the legacy path. For Foundry use `AnthropicFoundry` / `FoundryBackend` / `AnthropicFoundryClient` where the SDK supports it (C#, Java, PHP, Python, TypeScript); Go and Ruby have no Foundry client — Ruby's documented fallback is the first-party client with a custom `base_url`. Per-language table above.\n- **Don't define custom types for SDK data structures:** The SDK exports types for all API objects. Use `Anthropic.MessageParam` for messages, `Anthropic.Tool` for tool definitions, `Anthropic.ToolUseBlock` / `Anthropic.ToolResultBlockParam` for tool results, `Anthropic.Message` for responses. Defining your own `interface ChatMessage { role: string; content: unknown }` duplicates what the SDK already provides and loses type safety.\n- **Report and document output:** For tasks that produce reports, documents, or visualizations, the code execution sandbox has `python-docx`, `python-pptx`, `matplotlib`, `pillow`, and `pypdf` pre-installed. Claude can generate formatted files (DOCX, PDF, charts) and return them via the Files API — consider this for \"report\" or \"document\" type requests instead of plain stdout text.\n- **Server-tool errors don't raise.** Web search and web fetch errors return HTTP 200 with a `web_search_tool_result` / `web_fetch_tool_result` block whose `content` is a single error object (e.g. `{error_code: \"max_uses_exceeded\"}`) — not a raised exception. For web search, a success `content` is a *list*; an error `content` is an *object* — branch on that before indexing.\n- **Code execution output block type:** `code_execution_20260521` returns `bash_code_execution_tool_result` (with `.content.stdout`), **not** the legacy bare `code_execution_tool_result`. Iterate `response.content` and match on the correct type.\n- **Tool search: never defer everything.** The search tool itself must not have `defer_loading: true`, and at least one tool in `tools` must be non-deferred, or the API returns 400 `All tools have defer_loading set`.\n- **`strict: true` goes on the tool, not `tool_choice`.** Putting `strict` on `tool_choice` does nothing; it's a sibling of `name`/`description`/`input_schema` on the tool definition itself.\n- **Parallel tool results go in ONE user message.** Splitting `tool_result` blocks across multiple user messages silently trains Claude to stop making parallel calls. One assistant message of `tool_use` blocks → one user message of `tool_result` blocks.\n- **Citations + structured outputs are incompatible.** Enabling `citations: {enabled: true}` on a document while also setting `output_config.format` returns a 400.\n- **Batch results are unordered.** Match by `custom_id`, never by position in the results stream.\n- **Vertex model IDs have no prefix.** Unlike Bedrock's `anthropic.`-prefixed IDs, Vertex takes the bare first-party ID for current-generation models (e.g. `\"claude-opus-4-8\"`); dated-snapshot models use an `@` separator (e.g. `claude-haiku-4-5@20251001`).\n- **`stop_details` is `null` unless `stop_reason == \"refusal\"`.** For `max_tokens`, `end_turn`, etc., `stop_details` is `null` — guard before reading `.category`.\n- **WIF auth: unset `ANTHROPIC_API_KEY`, `ANTHROPIC_AUTH_TOKEN`, and `ANTHROPIC_PROFILE`.** `ANTHROPIC_API_KEY` and `ANTHROPIC_AUTH_TOKEN` (even set to `\"\"`) outrank Workload Identity Federation in the SDK's precedence chain and silently win; a set `ANTHROPIC_PROFILE` also wins (a missing named profile is an error, not a fall-through). `unset` them, don't blank them."}]},"isMeta":true,"uuid":"c3ad0b69-8280-4ecd-9a9c-b04eaaf1b9dd","timestamp":"2026-07-06T01:47:25.453Z","sourceToolUseID":"toolu_01UcSpnbk388HaCrXHCQ8yT6","session_id":"08068d9c-dc6a-455c-8543-099f90f23b64","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"08068d9c-dc6a-455c-8543-099f90f23b64","version":"2.1.201","gitBranch":"master"} 56 56 + {"parentUuid":"c3ad0b69-8280-4ecd-9a9c-b04eaaf1b9dd","isSidechain":false,"attachment":{"type":"command_permissions","allowedTools":["Read","Grep","Glob","WebFetch"]},"type":"attachment","uuid":"1bf7d634-777a-4eb6-bb98-69e9c67a0735","timestamp":"2026-07-06T01:47:25.453Z","session_id":"08068d9c-dc6a-455c-8543-099f90f23b64","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"08068d9c-dc6a-455c-8543-099f90f23b64","version":"2.1.201","gitBranch":"master"} 57 57 + {"type":"last-prompt","lastPrompt":"How would I add a field for the total cost for uncached input, cached input, output, and total token cost based on current claude API prices?

The run above puts your all-time total at about **$12,439**, of which $12,253 is Opus 4.8 (dominated by $6,375 of cache reads and $3,770 of uncached input).\n\nHow the costs are computed, since the raw buckets don't map one-to-one onto billing rates:\n\n- **Cached input** bills at 0.1× the model's input rate (cache reads).\n- **Uncached input** is split internally: fresh `input_tokens` at the base rate, plus cache *writes* at their TTL premium — 2× for 1-hour writes, 1.25× for 5-minute writes. Your session logs record the TTL breakdown in `usage.cache_creation` (Claude Code uses 1-hour caching), so this is exact; entries missing the breakdown fall back to the cheaper 1.25× assumption. The reported `uncachedInputTokens` bucket is unchanged — only the cost accounts for the premium.\n- **Output** bills at the model's output rate, and **total** is the sum of the three.\n\nPrices are current API list prices per the Claude API reference: Opus 4.x $5/$25 per MTok, Fable 5 $10/$50, Sonnet 4.6 $3/$15, Haiku 4.5 $1/$5. One judgment call: Sonnet 5 is priced at its introductory $2/$10 (in effect through 2026-08-31, sticker $3/$15) — it's a comment-flagged constant in the `PRICES` table if you'd rather use the sticker rate.

Tools can parse commits to generate CHANGELOG.md\n- **Semantic versioning** - Commit types map to version bumps (feat → minor, breaking → major)\n- **Clear project history** - Standardized format makes git log readable\n- **Automated releases** - CI/CD can trigger releases based on commit types\n\n## Quick Reference\n\n| Type | Use For | Version Bump |\n| ---- | ------- | ------------ |\n| `feat` | New feature | MINOR |\n| `fix` | Bug fix | PATCH |\n| `docs` | Documentation only | PATCH |\n| `style` | Formatting, no logic change | PATCH |\n| `refactor` | Code restructuring, no behavior change | PATCH |\n| `perf` | Performance improvement | PATCH |\n| `test` | Adding or updating tests | PATCH |\n| `build` | Build system or dependencies | PATCH |\n| `ci` | CI/CD configuration | PATCH |\n| `chore` | Maintenance, no user-facing change | PATCH |\n| `revert` | Revert a previous commit | PATCH |\n\n## Format\n\n```text\n<type>[optional scope]: <description>\n\n[optional body]\n\n[optional footer(s)]\n```\n\n**Rules:**\n\n- Type is required\n- Scope is optional - use parenthesized section affected: `(api)`, `auth)`, `parser)`\n- Description is required\n- Keep description concise, imperative mood, lowercase, no trailing period\n- Body and footer are optional\n- Separate subject from body with blank line\n- Wrap body at 72 characters\n\n## Examples\n\n```text\nfeat: add user authentication\n\nImplement JWT-based authentication with login/logout endpoints.\nIncludes password hashing and session management.\n\nCloses: #123\n```\n\n```text\nfix(api): handle null response from server\n\nPrevious implementation crashed when server returned null.\nNow returns empty result set.\n\nAssisted-by: GLM 4.6 via Claude Code\n```\n\n```text\nfeat(storage)!: change bucket listing API\n\nBREAKING CHANGE: bucket list now returns async iterator\ninstead of array. Update all callers to use for-await.\n```\n\n```text\nrefactor(core): simplify error handling\n\nConsolidate duplicate error handlers into single utility.\nNo behavior changes - internal cleanup only.\n```\n\n```text\nrevert: feat(auth): add OAuth support\n\nThis reverts commit 8b5a1c2. OAuth provider changed\ntheir API and we need to redesign integration.\n```\n\n## Breaking Changes\n\nIndicate breaking changes in two ways:\n\n**Option 1**: Add `!` after type/scope\n\n```text\nfeat(api)!: remove deprecated endpoint\n```\n\n**Option 2**: Add `BREAKING CHANGE:` footer\n\n```text\nfeat(api): remove deprecated endpoint\n\nBREAKING CHANGE: endpoint no longer exists. Use newEndpoint instead.\n```\n\n## AI Attribution\n\nAI agents must disclose their assistance in the commit footer:\n\n```text\nAssisted-by: [Model Name] via [Tool Name]\n```\n\nExamples:\n\n- `Assisted-by: GLM 4.6 via Claude Code`\n- `Assisted-by: Claude Opus 4.5 via claude.ai`\n\n## Common Mistakes\n\n| Mistake | Why Wrong | Correct |\n| ------- | --------- | ------- |\n| `Added login feature` | Past tense, capitalized | `feat: add login feature` |\n| `fix bug.` | Trailing period | `fix: resolve login error` |\n| `update` | Missing type | `chore: update dependencies` |\n| `feature:add-auth` | Missing space after colon | `feat: add authentication` |\n| `FEAT: big change` | Uppercase type | `feat: add authentication` |\n| Multi-line description no blank line | No separation | Add blank line after subject |\n\n## Body Guidelines\n\n- **What**: Motivation for the change (vs. code comments describe HOW)\n- **Contrast**: Explain the WHY and WHAT, not code details\n- **Wrap at 72 characters** for readability in git log\n\n```text\nfeat(summarization): add support for nested bullet points\n\nPrevious implementation only flattened all content. Now preserves\nhierarchy by respecting indentation levels. Users can now create\nstructured summaries with parent-child relationships.\n\nCloses: #456\n```\n\n## Footer Guidelines\n\nUse footers for:\n\n- **Breaking changes**: `BREAKING CHANGE: detailed explanation`\n- **Issue references**: `Closes: #123`, `Fixes: #456`, `Refs: #789`\n- **AI attribution**: `Assisted-by: Model via Tool`\n\nMultiple footers separated by blank lines:\n\n```text\nfeat: add batch upload\n\nImplements multipart upload for large files.\n\nBREAKING CHANGE: upload() signature changed - now requires options object\nCloses: #123\nAssisted-by: GLM 4.6 via Claude Code\n```\n\n## Git Commit Flags\n\n**Required flag:** Always use `--signoff` when committing:\n\n```bash\ngit commit --signoff -m \"feat: add user authentication\"\n```\n\nThe `--signoff` flag adds a `Signed-off-by` trailer to the commit message, indicating the committer has certified the commit follows developer certificate of origin (DCO).\n\n## Testing Your Commit\n\nBefore committing, verify:\n\n1.

It's the one remaining verified finding if you ever want it done in a dedicated session.\n- The **`is_oper`** agent was the one you moved from Fable → Sonnet mid-flight; its partial work was kept and finished.\n- The **umode** agent found my premise was slightly wrong (the two lists were a 10-set and a 13-set, not identical) and split the predicate correctly rather than collapsing them and reviving the slice-251 bug.\n\nEvery fix was written test-first, builds clean with no warnings, and passed its targeted tests with no snapshot drift. I updated the user-mode-wiring memory to reflect that the self-settable/umode-diff lists and the operator check are now single-sourced, so future work won't re-describe them as hand-paired allowlists."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1095,"cache_read_input_tokens":154592,"output_tokens":1122,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1095,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":1122,"cache_read_input_tokens":154592,"cache_creation_input_tokens":1095,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1095},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CchdFAWwWsSWjUB6hwZRM","type":"assistant","uuid":"f272c57a-7b9a-4e9a-946f-cecb359148b0","timestamp":"2026-07-04T20:11:23.615Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"5afb6f54-a28b-4d54-abb4-024e2406a27c","version":"2.1.201","gitBranch":"master"} 390 390 {"parentUuid":"f272c57a-7b9a-4e9a-946f-cecb359148b0","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"201f9f61-6c36-48b1-91f9-1edded3279cf","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":59},"type":"attachment","uuid":"25f7c028-cde1-423c-adf5-e8d88a26b752","timestamp":"2026-07-04T20:11:23.694Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"5afb6f54-a28b-4d54-abb4-024e2406a27c","version":"2.1.201","gitBranch":"master"} 391 391 {"parentUuid":"25f7c028-cde1-423c-adf5-e8d88a26b752","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":59},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":14}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-04T20:11:23.695Z","uuid":"4ffaa0b2-ceae-4349-a167-6c4b93b08590","toolUseID":"201f9f61-6c36-48b1-91f9-1edded3279cf","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"5afb6f54-a28b-4d54-abb4-024e2406a27c","version":"2.1.201","gitBranch":"master"} 392 392 + {"type":"file-history-snapshot","messageId":"d3373af8-ed08-484b-8d0b-d97f4b0167f5","snapshot":{"messageId":"d3373af8-ed08-484b-8d0b-d97f4b0167f5","trackedFileBackups":{"/home/xe/.claude/projects/-home-xe-Code-xeiaso-net-ircd-rs/memory/leveva-user-mode-wiring.md":{"backupFileName":"ebba4c09f0728443@v2","version":2,"backupTime":"2026-07-04T20:12:43.370Z"}},"timestamp":"2026-07-04T20:12:43.370Z"},"isSnapshotUpdate":false} 393 393 + {"parentUuid":"4ffaa0b2-ceae-4349-a167-6c4b93b08590","isSidechain":false,"promptId":"e86504f9-bea4-4705-81aa-7c7d3689c72b","type":"user","message":{"role":"user","content":"<command-message>conventional-commits</command-message>\n<command-name>/conventional-commits</command-name>"},"uuid":"d3373af8-ed08-484b-8d0b-d97f4b0167f5","timestamp":"2026-07-04T20:12:43.351Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"5afb6f54-a28b-4d54-abb4-024e2406a27c","version":"2.1.201","gitBranch":"master"} 394 394 + {"parentUuid":"d3373af8-ed08-484b-8d0b-d97f4b0167f5","isSidechain":false,"promptId":"e86504f9-bea4-4705-81aa-7c7d3689c72b","type":"user","message":{"role":"user","content":[{"type":"text","text":"Base directory for this skill: /home/xe/.claude/skills/conventional-commits\n\n# Conventional Commits\n\nStructured commit message format for version control that provides clear, readable project history.\n\n## Overview\n\nThe Conventional Commits specification provides:\n\n- **Automated changelog generation** - Tools can parse commits to generate CHANGELOG.md\n- **Semantic versioning** - Commit types map to version bumps (feat → minor, breaking → major)\n- **Clear project history** - Standardized format makes git log readable\n- **Automated releases** - CI/CD can trigger releases based on commit types\n\n## Quick Reference\n\n| Type | Use For | Version Bump |\n| ---- | ------- | ------------ |\n| `feat` | New feature | MINOR |\n| `fix` | Bug fix | PATCH |\n| `docs` | Documentation only | PATCH |\n| `style` | Formatting, no logic change | PATCH |\n| `refactor` | Code restructuring, no behavior change | PATCH |\n| `perf` | Performance improvement | PATCH |\n| `test` | Adding or updating tests | PATCH |\n| `build` | Build system or dependencies | PATCH |\n| `ci` | CI/CD configuration | PATCH |\n| `chore` | Maintenance, no user-facing change | PATCH |\n| `revert` | Revert a previous commit | PATCH |\n\n## Format\n\n```text\n<type>[optional scope]: <description>\n\n[optional body]\n\n[optional footer(s)]\n```\n\n**Rules:**\n\n- Type is required\n- Scope is optional - use parenthesized section affected: `(api)`, `auth)`, `parser)`\n- Description is required\n- Keep description concise, imperative mood, lowercase, no trailing period\n- Body and footer are optional\n- Separate subject from body with blank line\n- Wrap body at 72 characters\n\n## Examples\n\n```text\nfeat: add user authentication\n\nImplement JWT-based authentication with login/logout endpoints.\nIncludes password hashing and session management.\n\nCloses: #123\n```\n\n```text\nfix(api): handle null response from server\n\nPrevious implementation crashed when server returned null.\nNow returns empty result set.\n\nAssisted-by: GLM 4.6 via Claude Code\n```\n\n```text\nfeat(storage)!: change bucket listing API\n\nBREAKING CHANGE: bucket list now returns async iterator\ninstead of array. Update all callers to use for-await.\n```\n\n```text\nrefactor(core): simplify error handling\n\nConsolidate duplicate error handlers into single utility.\nNo behavior changes - internal cleanup only.\n```\n\n```text\nrevert: feat(auth): add OAuth support\n\nThis reverts commit 8b5a1c2. OAuth provider changed\ntheir API and we need to redesign integration.\n```\n\n## Breaking Changes\n\nIndicate breaking changes in two ways:\n\n**Option 1**: Add `!` after type/scope\n\n```text\nfeat(api)!: remove deprecated endpoint\n```\n\n**Option 2**: Add `BREAKING CHANGE:` footer\n\n```text\nfeat(api): remove deprecated endpoint\n\nBREAKING CHANGE: endpoint no longer exists. Use newEndpoint instead.\n```\n\n## AI Attribution\n\nAI agents must disclose their assistance in the commit footer:\n\n```text\nAssisted-by: [Model Name] via [Tool Name]\n```\n\nExamples:\n\n- `Assisted-by: GLM 4.6 via Claude Code`\n- `Assisted-by: Claude Opus 4.5 via claude.ai`\n\n## Common Mistakes\n\n| Mistake | Why Wrong | Correct |\n| ------- | --------- | ------- |\n| `Added login feature` | Past tense, capitalized | `feat: add login feature` |\n| `fix bug.` | Trailing period | `fix: resolve login error` |\n| `update` | Missing type | `chore: update dependencies` |\n| `feature:add-auth` | Missing space after colon | `feat: add authentication` |\n| `FEAT: big change` | Uppercase type | `feat: add authentication` |\n| Multi-line description no blank line | No separation | Add blank line after subject |\n\n## Body Guidelines\n\n- **What**: Motivation for the change (vs. code comments describe HOW)\n- **Contrast**: Explain the WHY and WHAT, not code details\n- **Wrap at 72 characters** for readability in git log\n\n```text\nfeat(summarization): add support for nested bullet points\n\nPrevious implementation only flattened all content. Now preserves\nhierarchy by respecting indentation levels. Users can now create\nstructured summaries with parent-child relationships.\n\nCloses: #456\n```\n\n## Footer Guidelines\n\nUse footers for:\n\n- **Breaking changes**: `BREAKING CHANGE: detailed explanation`\n- **Issue references**: `Closes: #123`, `Fixes: #456`, `Refs: #789`\n- **AI attribution**: `Assisted-by: Model via Tool`\n\nMultiple footers separated by blank lines:\n\n```text\nfeat: add batch upload\n\nImplements multipart upload for large files.\n\nBREAKING CHANGE: upload() signature changed - now requires options object\nCloses: #123\nAssisted-by: GLM 4.6 via Claude Code\n```\n\n## Git Commit Flags\n\n**Required flag:** Always use `--signoff` when committing:\n\n```bash\ngit commit --signoff -m \"feat: add user authentication\"\n```\n\nThe `--signoff` flag adds a `Signed-off-by` trailer to the commit message, indicating the committer has certified the commit follows developer certificate of origin (DCO).\n\n## Testing Your Commit\n\nBefore committing, verify:\n\n1. [ ] Type is from allowed list\n2. [ ] Description is imperative mood (add, fix, update)\n3. [ ] Description is lowercase\n4. [ ] No trailing period on description\n5. [ ] Breaking changes marked with `!` or footer\n6. [ ] AI attribution included (if applicable)\n7. [ ] Body explains WHY not HOW\n8. [ ] Using `--signoff` flag\n"}]},"isMeta":true,"uuid":"a4172874-cf30-4c66-abbf-b9e662f13dae","timestamp":"2026-07-04T20:12:43.351Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"5afb6f54-a28b-4d54-abb4-024e2406a27c","version":"2.1.201","gitBranch":"master"}

YOU MUST USE IT.\n\nThis is not negotiable. You cannot rationalize your way out of this.\n</EXTREMELY-IMPORTANT>\n\n## The Rule\n\n**Invoke relevant or requested skills BEFORE any response or action** — including clarifying questions, exploring the codebase, or checking files. If it turns out wrong for the situation, you don't have to use it.\n\n**Before entering plan mode:** if you haven't already brainstormed, invoke the brainstorming skill first.\n\nThen announce \"Using [skill] to [purpose]\" and follow the skill exactly. If it has a checklist, create a todo per item.\n\n## Skill Priority\n\nWhen multiple skills apply, process skills come first — they set the approach, then implementation skills (frontend-design, etc.) carry it out. Brainstorming and systematic-debugging are Superpowers' most common process skills, but the rule holds for any of them.\n\n- \"Let's build X\" → superpowers:brainstorming first, then implementation skills.\n- \"Fix this bug\" → superpowers:systematic-debugging first, then domain skills.\n\n## Red Flags\n\nThese thoughts mean STOP—you're rationalizing:\n\n| Thought | Reality |\n|---------|---------|\n| \"This is just a simple question\" | Questions are tasks. Check for skills. |\n| \"I need more context first\" | Skill check comes BEFORE clarifying questions. |\n| \"Let me explore the codebase first\" | Skills tell you HOW to explore. Check first. |\n| \"I can check git/files quickly\" | Files lack conversation context. Check for skills. |\n| \"Let me gather information first\" | Skills tell you HOW to gather information. |\n| \"This doesn't need a formal skill\" | If a skill exists, use it. |\n| \"I remember this skill\" | Skills evolve. Read current version. |\n| \"This doesn't count as a task\" | Action = task. Check for skills. |\n| \"The skill is overkill\" | Simple things become complex. Use it. |\n| \"I'll just do this one thing first\" | Check BEFORE doing anything. |\n| \"This feels productive\" | Undisciplined action wastes time. Skills prevent this. |\n| \"I know what that means\" | Knowing the concept ≠ using the skill.

(Tools: *)","- claude-code-guide: Use this agent when the user asks questions (\"Can Claude...\", \"Does Claude...\", \"How do I...\") about: (1) Claude Code (the CLI tool) - features, hooks, slash commands, MCP servers, settings, IDE integrations, keyboard shortcuts; (2) Claude Agent SDK - building custom agents; (3) Claude API (formerly Anthropic API) - API usage, tool use, Anthropic SDK usage. **IMPORTANT:** Before spawning a new agent, check if there is already a running or recently completed claude-code-guide agent that you can continue via SendMessage. (Tools: Bash, Read, WebFetch, WebSearch)","- Explore: Read-only search agent for broad fan-out searches — when answering means sweeping many files, directories, or naming conventions and you only need the conclusion, not the file dumps. It reads excerpts rather than whole files, so it locates code; it doesn't review or audit it. Specify search breadth: \"medium\" for moderate exploration, \"very thorough\" for multiple locations and naming conventions. (Tools: All tools except Agent, Artifact, ExitPlanMode, Edit, Write, NotebookEdit)","- general-purpose: General-purpose agent for researching complex questions, searching for code, and executing multi-step tasks. When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries use this agent to perform the search for you. (Tools: *)","- let-fate-decide:draw: Draw the 12 Houses of the Zodiac Tarot spread and return a concise structured reading. Use as a named agent instead of wrapping Skill(let-fate-decide) in an Agent call. Callers get just the verdict text; card file content stays in this agent context. (Tools: Bash)","- Plan: Software architect agent for designing implementation plans. Use this when you need to plan the implementation strategy for a task. Returns step-by-step plans, identifies critical files, and considers architectural trade-offs.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern.

Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the

Update all callers to use for-await.\n```\n\n```text\nrefactor(core): simplify error handling\n\nConsolidate duplicate error handlers into single utility.\nNo behavior changes - internal cleanup only.\n```\n\n```text\nrevert: feat(auth): add OAuth support\n\nThis reverts commit 8b5a1c2. OAuth provider changed\ntheir API and we need to redesign integration.\n```\n\n## Breaking Changes\n\nIndicate breaking changes in two ways:\n\n**Option 1**: Add `!` after type/scope\n\n```text\nfeat(api)!: remove deprecated endpoint\n```\n\n**Option 2**: Add `BREAKING CHANGE:` footer\n\n```text\nfeat(api): remove deprecated endpoint\n\nBREAKING CHANGE: endpoint no longer exists. Use newEndpoint instead.\n```\n\n## AI Attribution\n\nAI agents must disclose their assistance in the commit footer:\n\n```text\nAssisted-by: [Model Name] via [Tool Name]\n```\n\nExamples:\n\n- `Assisted-by: GLM 4.6 via Claude Code`\n- `Assisted-by: Claude Opus 4.5 via claude.ai`\n\n## Common Mistakes\n\n| Mistake | Why Wrong | Correct |\n| ------- | --------- | ------- |\n| `Added login feature` | Past tense, capitalized | `feat: add login feature` |\n| `fix bug.` | Trailing period | `fix: resolve login error` |\n| `update` | Missing type | `chore: update dependencies` |\n| `feature:add-auth` | Missing space after colon | `feat: add authentication` |\n| `FEAT: big change` | Uppercase type | `feat: add authentication` |\n| Multi-line description no blank line | No separation | Add blank line after subject |\n\n## Body Guidelines\n\n- **What**: Motivation for the change (vs. code comments describe HOW)\n- **Contrast**: Explain the WHY and WHAT, not code details\n- **Wrap at 72 characters** for readability in git log\n\n```text\nfeat(summarization): add support for nested bullet points\n\nPrevious implementation only flattened all content. Now preserves\nhierarchy by respecting indentation levels. Users can now create\nstructured summaries with parent-child relationships.\n\nCloses: #456\n```\n\n## Footer Guidelines\n\nUse footers for:\n\n- **Breaking changes**: `BREAKING CHANGE: detailed explanation`\n- **Issue references**: `Closes: #123`, `Fixes: #456`, `Refs: #789`\n- **AI attribution**: `Assisted-by: Model via Tool`\n\nMultiple footers separated by blank lines:\n\n```text\nfeat: add batch upload\n\nImplements multipart upload for large files.\n\nBREAKING CHANGE: upload() signature changed - now requires options object\nCloses: #123\nAssisted-by: GLM 4.6 via Claude Code\n```\n\n## Git Commit Flags\n\n**Required flag:** Always use `--signoff` when committing:\n\n```bash\ngit commit --signoff -m \"feat: add user authentication\"\n```\n\nThe `--signoff` flag adds a `Signed-off-by` trailer to the commit message, indicating the committer has certified the commit follows developer certificate of origin (DCO).\n\n## Testing Your Commit\n\nBefore committing, verify:\n\n1. [ ] Type is from allowed list\n2. [ ] Description is imperative mood (add, fix, update)\n3. [ ] Description is lowercase\n4. [ ] No trailing period on description\n5. [ ] Breaking changes marked with `!` or footer\n6. [ ] AI attribution included (if applicable)\n7. [ ] Body explains WHY not HOW\n8. [ ] Using `--signoff` flag\n"}]},"isMeta":true,"uuid":"d81eafd5-5004-488a-a7d8-20d1feea9325","timestamp":"2026-07-06T01:34:24.034Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"92159a90-e74f-41aa-b0ae-9a16ab2e4d90","version":"2.1.201","gitBranch":"master"}

For all other skills, use the 'Skill' tool:**\\n\\n---\\nname: using-superpowers\\ndescription: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\\n---\\n\\n<SUBAGENT-STOP>\\nIf you were dispatched as a subagent to execute a specific task, ignore this skill.\\n</SUBAGENT-STOP>\\n\\n<EXTREMELY-IMPORTANT>\\nIf you think there is even a 1% chance a skill might apply to what you are doing, you ABSOLUTELY MUST invoke the skill.\\n\\nIF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.\\n\\nThis is not negotiable. You cannot rationalize your way out of this.\\n</EXTREMELY-IMPORTANT>\\n\\n## The Rule\\n\\n**Invoke relevant or requested skills BEFORE any response or action** — including clarifying questions, exploring the codebase, or checking files. If it turns out wrong for the situation, you don't have to use it.\\n\\n**Before entering plan mode:** if you haven't already brainstormed, invoke the brainstorming skill first.\\n\\nThen announce \\\"Using [skill] to [purpose]\\\" and follow the skill exactly. If it has a checklist, create a todo per item.\\n\\n## Skill Priority\\n\\nWhen multiple skills apply, process skills come first — they set the approach, then implementation skills (frontend-design, etc.) carry it out. Brainstorming and systematic-debugging are Superpowers' most common process skills, but the rule holds for any of them.\\n\\n- \\\"Let's build X\\\" → superpowers:brainstorming first, then implementation skills.\\n- \\\"Fix this bug\\\" → superpowers:systematic-debugging first, then domain skills.\\n\\n## Red Flags\\n\\nThese thoughts mean STOP—you're rationalizing:\\n\\n| Thought | Reality |\\n|---------|---------|\\n| \\\"This is just a simple question\\\" | Questions are tasks. Check for skills. |\\n| \\\"I need more context first\\\" | Skill check comes BEFORE clarifying questions. |\\n| \\\"Let me explore the codebase first\\\" | Skills tell you HOW to explore. Check first. |\\n| \\\"I can check git/files quickly\\\" | Files lack conversation context. Check for skills. |\\n| \\\"Let me gather information first\\\" | Skills tell you HOW to gather information. |\\n| \\\"This doesn't need a formal skill\\\" | If a skill exists, use it. |\\n| \\\"I remember this skill\\\" | Skills evolve. Read current version. |\\n| \\\"This doesn't count as a task\\\" | Action = task. Check for skills. |\\n| \\\"The skill is overkill\\\" | Simple things become complex. Use it. |\\n| \\\"I'll just do this one thing first\\\" | Check BEFORE doing anything. |\\n| \\\"This feels productive\\\" | Undisciplined action wastes time.

For all other skills, use the 'Skill' tool:**\n\n---\nname: using-superpowers\ndescription: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n---\n\n<SUBAGENT-STOP>\nIf you were dispatched as a subagent to execute a specific task, ignore this skill.\n</SUBAGENT-STOP>\n\n<EXTREMELY-IMPORTANT>\nIf you think there is even a 1% chance a skill might apply to what you are doing, you ABSOLUTELY MUST invoke the skill.\n\nIF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.\n\nThis is not negotiable. You cannot rationalize your way out of this.\n</EXTREMELY-IMPORTANT>\n\n## The Rule\n\n**Invoke relevant or requested skills BEFORE any response or action** — including clarifying questions, exploring the codebase, or checking files. If it turns out wrong for the situation, you don't have to use it.\n\n**Before entering plan mode:** if you haven't already brainstormed, invoke the brainstorming skill first.\n\nThen announce \"Using [skill] to [purpose]\" and follow the skill exactly. If it has a checklist, create a todo per item.\n\n## Skill Priority\n\nWhen multiple skills apply, process skills come first — they set the approach, then implementation skills (frontend-design, etc.) carry it out. Brainstorming and systematic-debugging are Superpowers' most common process skills, but the rule holds for any of them.\n\n- \"Let's build X\" → superpowers:brainstorming first, then implementation skills.\n- \"Fix this bug\" → superpowers:systematic-debugging first, then domain skills.\n\n## Red Flags\n\nThese thoughts mean STOP—you're rationalizing:\n\n| Thought | Reality |\n|---------|---------|\n| \"This is just a simple question\" | Questions are tasks. Check for skills. |\n| \"I need more context first\" | Skill check comes BEFORE clarifying questions. |\n| \"Let me explore the codebase first\" | Skills tell you HOW to explore. Check first. |\n| \"I can check git/files quickly\" | Files lack conversation context. Check for skills. |\n| \"Let me gather information first\" | Skills tell you HOW to gather information. |\n| \"This doesn't need a formal skill\" | If a skill exists, use it. |\n| \"I remember this skill\" | Skills evolve. Read current version. |\n| \"This doesn't count as a task\" | Action = task. Check for skills. |\n| \"The skill is overkill\" | Simple things become complex. Use it. |\n| \"I'll just do this one thing first\" | Check BEFORE doing anything. |\n| \"This feels productive\" | Undisciplined action wastes time. Skills prevent this. |\n| \"I know what that means\" | Knowing the concept ≠ using the skill.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern. Use when creating database models, writing queries, setting up GORM, adding CRUD methods, or working with gorm.io in Go services.

Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":87,"isInitial":true,"names":["conventional-commits","finishing-a-development-branch","command-cluster-port","create-blogpost","deep-research","mind:ask","mind:recent","mind:search","mind:stats","product-management:brainstorm","ralph-loop:cancel-ralph","ralph-loop:help","ralph-loop:ralph-loop","ctx-agent-history-search:ctx-history","mind:memory","mind:mind","10x-Team:10x-team","10x-Team:cto","10x-Team:dba","10x-Team:devops-engineer","10x-Team:engineering-manager","10x-Team:principal-architect","10x-Team:product-manager","10x-Team:qa-engineer","10x-Team:sde","10x-Team:security-engineer","10x-Team:senior-engineer","10x-Team:sre","10x-Team:staff-engineer","autoresearch:autoresearch","autoresearch:autoresearch-discover","tigris-storage:tigris-access-keys","tigris-storage:tigris-authentication","tigris-storage:tigris-buckets","tigris-storage:tigris-iam","tigris-storage:tigris-objects","product-management:competitive-brief","product-management:metrics-review","product-management:product-brainstorming","product-management:roadmap-update","product-management:sprint-planning","product-management:stakeholder-update","product-management:synthesize-research","product-management:write-spec","frontend-design:frontend-design","let-fate-decide:let-fate-decide","xe-design:xe-design-system","xe-go:go-table-driven-tests","xe-go:gorm-dao","xe-go:xe-go-style","xe-templ:templ-components","xe-templ:templ-htmx","xe-templ:templ-http","xe-templ:templ-syntax","xe-writing:excalidraw-diagrams","xe-writing:sound-like-a-person","xe-writing:xe-writing-style","ctx-agent-history-search:ctx-agent-history-search","superpowers:brainstorming","superpowers:dispatching-parallel-agents","superpowers:executing-plans","superpowers:finishing-a-development-branch","superpowers:receiving-code-review","superpowers:requesting-code-review","superpowers:subagent-driven-development","superpowers:systematic-debugging","superpowers:test-driven-development","superpowers:using-git-worktrees","superpowers:using-superpowers","superpowers:verification-before-completion","superpowers:writing-plans","superpowers:writing-skills","dataviz","artifact-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"ba4ac505-506f-4350-adf0-6eab48d86214","timestamp":"2026-07-04T20:54:53.530Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 16 16 + {"type":"last-prompt","lastPrompt":"If I was writing a human-authored blogpost about this entire experiment, what would be a good bullet point outline of this entire process?

Mechanically rewrite IRCnet ircd 2.11 from C to Rust (strangler fig)\n\n## Context\n\n`ircd.rs` is the IRCnet ircd 2.11 IRC daemon: ~51k LOC of C across `common/`, `ircd/`, and `iauth/`,\nproducing 5 binaries (`ircd`, `iauth`, `chkconf`, `ircdwatch`, `mkpasswd`). It is a single‑threaded\n`select()/poll()` server with a table‑driven command dispatcher, a bundled BIND DNS resolver, pervasive\nfixed‑size buffers, and ~230 `strcpy/sprintf`‑family calls — i.e. exactly the memory‑safety profile a\nRust rewrite is meant to eliminate. There are **no existing tests** (only a clang‑format CI check).\n\nGoal: convert the codebase to Rust **module‑by‑module**, keeping the program building and running at\nevery step, with **every important part fully tested** against the original C as a reference oracle.\n\nThis plan reflects four locked decisions from the user:\n\n1. **Faithful mechanical port now**, then **dedicated idiomatic‑Rust passes at the very end** (after C is gone). ⚠️ **Superseded (2026‑06‑08):** decision 1 originally meant an *in‑place* idiomatic transformation of the mechanical port (the old P9–P12). The project instead forked a **parallel greenfield idiomatic daemon, `leveva`**, tested differentially against the now‑complete mechanical port. So the idiomatic end‑state is reached by *growing `leveva` to parity and deleting the mechanical port*, not by polishing it in place. See the reframed P9–P12 below.\n2. **Rust‑driven build from day one**: `fn main()` is Rust; remaining C compiles as a `*-sys` crate; we strangle _inward_.\n3. **iauth rewritten first**, standalone greenfield Rust binary speaking the identical pipe protocol.\n4. **Full 4‑layer testing** (differential unit, golden, fuzz, conformance) + a **permanent C reference build** in CI.\n\nThe leverage point: every `foo.c` already ships `foo_ext.h` (its public `extern` API) — **41 headers / ~417 symbols** that form a ready‑made per‑module C ABI contract. Dispatch is a function‑pointer table (`msgtab[]` in `common/parse.c`). These two facts make the strangler seam tractable.\n\n---\n\n## The migration model (the seam)\n\n**Workspace.** A cargo workspace at repo root, coexisting with the untouched autoconf tree:\n\n- `ircd-sys/` — `build.rs` runs `support/configure` to generate `setup.h`/`config.h`, then `cc::Build` compiles the C objects (mirroring `IRCD_COMMON_OBJS`+`IRCD_OBJS` from `support/Makefile.in:144‑149`) **minus** whatever has been ported, plus `bindgen` over a `wrapper.h` that `#include`s `common/struct_def.h` + all `*_ext.h`/`*_def.h`.\n- `ircd-rs/` — the binary crate; `src/main.rs` owns the real `fn main()`. Ported modules live here / in leaf sub‑crates.\n- `iauth-rs/` — standalone greenfield `iauth` binary (no `ircd-sys` dep).\n- `ircd-testkit/` — the L1–L4 harness. `ircd-fuzz/` — `cargo-fuzz` targets.\n\n**Runnable baseline (day one).** Compile the C `main` (`ircd/ircd.c:766`) as `c_ircd_main` via `cc::Build::define(\"main\", Some(\"c_ircd_main\"))`. Rust `main()` marshals argc/argv and calls it. The product is byte‑for‑byte the C ircd, just entered from Rust. (Also generate `version.c` from `ircd/version.c.SH.in` in `build.rs` and compile it — the C link needs `version.o`.)\n\n**Strangling inward (per module).** To port `foo.c`: read `foo_ext.h` for the exact ABI; write Rust `#[no_mangle] pub extern \"C\" fn …` (and `#[no_mangle] pub static …` for exported data) matching the **exact** signatures (note: C uses mutable `char*`, not `const`); **remove `foo.c` from `build.rs`'s source list**. Because the `.c` is _dropped_ (not overridden), exactly one definition of each symbol exists at all times → no duplicate‑symbol/LTO games, program always links. Cross‑language LTO stays **off** during migration. CI builds + boots the server after every move.\n\n**Single source of truth for compile defines.** `build.rs` must mirror `Makefile.in` **per‑object** defines (e.g. `-DFNAME_USERLOG=…`, `-DIRCDCONF_PATH=…`, `CLIENT_COMPILE`), and feed the **identical** `-include config.h/setup.h` + `-D` set to `cc::Build`, to `bindgen`, **and** to the reference‑archive build. A divergence here silently corrupts `aClient` layout. Default config to lock: `USE_IAUTH` on, `XLINE` off, `ZIP_LINKS` off, `AFINET=AF_INET6` (so `IN_ADDR` = libc `in6_addr`).\n\n**Non‑ircd binaries are out of strangler scope.** `ircdwatch`, `chkconf`, `mkpasswd` and the `cl*.o` duplicate‑compiled common objects (`-DCLIENT_COMPILE`) stay in the **permanent C reference tree only**; they are never routed through `ircd-sys`. `chkconf` gets a Rust port opportunistically in P6.\n\n---\n\n## Keystone hazards & how we neutralize them (all verified in‑tree)\n\n| Hazard | Reality (verified) | Neutralization |\n| -------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| **C‑variadic exports** | ~14 in `send_ext.h` (`sendto_one`, `sendto_flag`, …) + `irc_sprintf`; stable Rust _cannot define_ an `extern \"C\"` variadic fn.

An oracle only needs to keep building + passing its tests — it does **not** need to be idiomatic, so the in‑place cleanup (old P9) is retired as throwaway work.\n\n| Phase | Modules | Approach & gotchas | Test gate (exit) |\n| ------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |","stderr":"","interrupted":false,"isImage":false,"noOutputExpected":false},"sourceToolAssistantUUID":"714281b6-d27e-4eb9-b607-6dad829f7d1f","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 30 30 + {"parentUuid":"2381cab5-e74a-45b1-8ca7-d284b96abbab","isSidechain":false,"attachment":{"type":"hook_success","hookName":"PostToolUse:Bash","toolUseID":"toolu_01UVseytRJCe17TxgKdWkJox","hookEvent":"PostToolUse","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/post-tool-use.js\"","durationMs":47},"type":"attachment","uuid":"3d84f0ef-113a-44f3-b235-9189a44c06de","timestamp":"2026-07-04T20:55:17.885Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 31 31 + {"parentUuid":"3d84f0ef-113a-44f3-b235-9189a44c06de","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_011VzAEsmamAcSMEpnBY7gXs","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_018mZpyfvPCugNWS2E4RCC6f","name":"Bash","input":{"command":"git log --oneline --since=2026-05-01 | wc -l; git log --format='%ad %s' --date=short | grep -i 'rust\\|P0' | tail -5; grep -c '^## Slice' docs/progress-log/p11.md 2>/dev/null; tail -30 docs/progress-log/p11.md | head -20","description":"Count experiment-era commits and latest slice number"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":13634,"cache_read_input_tokens":32808,"output_tokens":537,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":13634,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":537,"cache_read_input_tokens":32808,"cache_creation_input_tokens":13634,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":13634},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cchgc1TfUtPXzXayvBXqs","type":"assistant","uuid":"c6095f19-6fce-49e3-88db-99f504a9f845","timestamp":"2026-07-04T20:55:19.751Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 32 32 + {"parentUuid":"c6095f19-6fce-49e3-88db-99f504a9f845","isSidechain":false,"promptId":"b932b4e0-d4fe-4718-8731-062f84eb8d7e","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_018mZpyfvPCugNWS2E4RCC6f","type":"tool_result","content":"1682\n2004-02-22 \"username\" can be longer than USERLEN -- it's supplied by client, after all.

an outline grounded in the repo's actual history (dates and numbers are from the git log and progress logs, so you can trust them):\n\n# My vibecoding experiment of an IRC daemon in Rust\n\n* Early June I decided to see how effectively Claude Opus could port an IRC daemon to Rust, then use that Rust version of the program as a correctness oracle to write a new IRC daemon in idiomatic Rust.\n* **The starting material**: IRCnet ircd 2.11 — ~51k lines of C with CVS history going back to 1997, a single-threaded `select()` loop, ~230 `strcpy`/`sprintf`-family calls, and exactly zero tests. The worst-case codebase for a rewrite, which is the point. (Bonus color: the preserved 90s commit messages, like \"never trust comstud ;)\".)\n* **The ground rules I locked in up front** (and why locking decisions early matters when working with an agent): faithful mechanical port first, idiomatic Rust only at the end; Rust owns `main()` from day one and strangles inward; the pristine C tree stays buildable forever as the reference oracle; everything gets differentially tested against it.\n* **The seam that made it tractable**: every `foo.c` already shipped a `foo_ext.h` with its exact extern API (~417 symbols), and command dispatch was a function-pointer table. Port a file → drop the `.c` from the build → exactly one definition of every symbol exists at all times → the program links and boots after every single move.\n* **Building the harness before porting anything**: `objcopy`-renaming the whole C build into a `cref_`-prefixed oracle archive so C and Rust versions of the same function link into one test binary; a golden harness that boots both daemons and byte-diffs their wire output; differential fuzzing through the real message-reassembly path.\n* **The hazards that would have sunk a naive port** (all found and neutralized along the way): C variadics that stable Rust literally cannot define (solved with thin C trampolines that lived until the last day), structs with interior self-pointers, a partial-allocation size trick for remote clients, struct layout that shifts under config `#define`s, bindgen quirks.\n* **The mechanical port** (P1–P7, about a week): leaf utilities → data structures → wire format and delivery → the parser → ~50 command handlers → iauth rewritten greenfield → finally the I/O core and event loop. June 7: every line of C *logic* is Rust.\n* **June 8, deleting the C**: trampolines replaced with `format!`, data globals migrated, the build script stops compiling a single C file. Gate: 698 tests green, zero warnings, 100% Rust.\n* **The pivot** — the part I find most interesting: the plan said \"now clean up the mechanical port in place.\" Instead I forked a greenfield idiomatic daemon (leveva: tokio, rustls, KDL config) and ran the strangler pattern *again, one level up* — the verified mechanical port became the behavioral oracle for the new daemon, exactly as the C had been for it. An oracle doesn't need to be pretty, it just needs to keep passing its tests, so the in-place cleanup was retired as throwaway work.\n* **Growing leveva to parity in 309 recorded slices**: the discipline that made it work — failing test written first, every slice gets a plan file + progress-log entry + its own commit, and the standing rule that kept it honest: *if the oracle supports something and leveva doesn't, that's a bug to close, not a divergence to document.*\n* **June 13, the strangler completes**: parity reached, so the mechanical port — the thing the first two weeks produced — gets deleted. The whole 51k-line faithful port was scaffolding, and it was always going to be.\n* **Then it stopped being a migration**: post-parity feature work the C daemon never had — IRCv3 (CAP, SASL, message tags, `server-time`, chathistory backed by SQLite), charybdis-style extbans and K/D-lines, KNOCK, flood protection, TLS server links, Prometheus metrics, hot REHASH of nearly everything.\n* **Running it in anger**: deployed as a real multi-server production network (ShadowNET), which is where the fun bugs lived — cross-server desyncs, timestamp-merge fights, a real leak audit against live RSS.\n* **What made the agent workflow actually work**: persistent memory files as an index of hard-won facts, custom skills, hard rules written down where the agent re-reads them (work on master, one test per commit, no DM history ever), and having Claude write a 24-post blog series about its own port as it went.\n* **The numbers**: ~1,700 commits in about five weeks, ~160k lines of Rust (tests included), 51k lines of C reduced to zero.\n* **Reflections** (stubs to fill in your own voice): what surprised you, where the model needed rails vs. where it ran free, whether the oracle-first method generalizes, and what you'd tell someone attempting the same with their own legacy C.\n\nA couple of framing thoughts: the strongest through-line is probably \"differential testing is what makes agentic rewrites trustworthy\" — the two-stage oracle chain (C → mechanical Rust → idiomatic Rust) is the novel bit, and the June 13 \"delete the thing you spent two weeks building\" moment is your natural midpoint climax. Also worth deciding early whether the post is about *IRC* or about *method* — the outline above leans method, with IRC as the vehicle."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1962,"cache_read_input_tokens":55202,"output_tokens":1869,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1962,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":1869,"cache_read_input_tokens":55202,"cache_creation_input_tokens":1962,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1962},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cchgi96xNvhks3dM9ynJK","type":"assistant","uuid":"6251ce86-5e15-4257-b443-d722a9e485c3","timestamp":"2026-07-04T20:57:03.211Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 51 51 + {"parentUuid":"6251ce86-5e15-4257-b443-d722a9e485c3","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"47b9c909-e329-4d3e-9371-de5c745b691d","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":88},"type":"attachment","uuid":"d7b70750-bc96-4671-9676-59344bcc3f97","timestamp":"2026-07-04T20:57:03.305Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 52 52 + {"parentUuid":"d7b70750-bc96-4671-9676-59344bcc3f97","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":88},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":51}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-04T20:57:03.306Z","uuid":"6416b0a2-a2a1-4e70-8138-8cc6129fa11d","toolUseID":"47b9c909-e329-4d3e-9371-de5c745b691d","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 53 53 + {"type":"last-prompt","lastPrompt":"If I was writing a human-authored blogpost about this entire experiment, what would be a good bullet point outline of this entire process?

answer: about a third of that outline is genuinely interesting, and the rest is scaffolding a reader in mid-2026 has seen before. \"Claude wrote a lot of Rust\" is not news anymore. Here's what I think actually clears the bar, ranked:\n\n**1. The disposable oracle — the two-stage strangler.** This is the real contribution. Everyone knows rewrites fail because you can't verify behavioral equivalence. Your answer was to *manufacture* the oracle: do a deliberately ugly, byte-faithful mechanical port whose only job is to be verifiable against the C, then use *that* as the test oracle for the daemon you actually wanted, then delete it. The load-bearing insight is the sentence from your own plan file: an oracle doesn't need to be idiomatic, it just needs to keep passing its tests — which is why the planned \"clean up the port in place\" phase was retired as throwaway work. Nobody else is writing about this shape. It's the thesis of the post.\n\n**2. What your job actually was.** The honest version of \"how do you supervise an agent writing 160k lines you'll never read\" is interesting; the sanitized version isn't. Your leverage was never code review — it was designing the verification structure (the differential harness, the byte-diff gates) and writing down hard rules in a place the agent re-reads: *oracle-supports-it-but-leveva-doesn't is a bug to close, not a divergence to document*. That rule is interesting because it names the specific failure mode of agents — they'd rather rationalize a gap than close it — and closes it structurally instead of by vigilance. Same with locking decisions up front so the agent can't re-litigate them at 3am.\n\n**3. The \"no tests\" paradox.** The codebase had zero tests and that turned out to be *fine*, because the program is its own test suite if you can diff its behavior. `objcopy`-renaming the entire C build to `cref_*` so the C and Rust versions of the same function link into one test binary and get called side by side — that's a concrete, reusable trick most readers won't know. This is the \"here's something you can steal\" section.\n\n**4. The one falsifiable technical wall: variadics.** Stable Rust cannot define an `extern \"C\"` variadic function, full stop, so ~25 tiny C trampolines had to survive until the very last day and \"100% Rust\" was a final-phase goal by necessity, not choice. One vivid, specific fact beats the whole hazards table. (The self-pointer structs and layout-drift stuff can be a sentence each; they're the same genre of finding.)\n\n**5. Deleting the port.** Structurally this is your midpoint beat: on June 13 you deleted the verified 51k-line-equivalent artifact the first two weeks produced, on purpose, because it was always scaffolding. Readers feel that. It also proves you meant point 1.\n\n**6. The caveat that makes it credible.** IRC was a *rigged* choice: it has a line-based wire protocol you can byte-diff, which is exactly what makes differential oracles cheap. The method generalizes only as far as your ability to find a diffable behavioral surface. Saying this out loud is more interesting than implying the method works everywhere — it tells the reader precisely when to try this on their own legacy C.\n\nWhat I'd demote or cut: the phase-by-phase chronology (compress to two sentences), the IRCv3/charybdis feature inventory (it's a changelog, not an idea), the commit/LOC counts as anything more than one throwaway line, and the production-deployment section *unless* you have one specific prod-only bug story — a cross-server desync makes a good anecdote, a paragraph saying \"it runs in production\" doesn't.\n\nThe post that's interesting is \"how to make an agent's output trustworthy without reading it,\" with IRC as the vehicle. The post that isn't is \"a tour of everything we built.\""}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":186,"cache_creation_input_tokens":1886,"cache_read_input_tokens":57164,"output_tokens":2265,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1886,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":186,"output_tokens":2265,"cache_read_input_tokens":57164,"cache_creation_input_tokens":1886,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1886},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cchgs3NRkiH7xZkv2RjfF","type":"assistant","uuid":"5105dbc8-e182-4dde-b9e4-79c5e166dcaf","timestamp":"2026-07-04T20:59:15.068Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 62 62 + {"parentUuid":"5105dbc8-e182-4dde-b9e4-79c5e166dcaf","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"df9eaa72-eed9-4097-b3aa-c5634642441c","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":67},"type":"attachment","uuid":"32073fe1-e077-4c19-9f38-a60310a7addc","timestamp":"2026-07-04T20:59:15.200Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 63 63 + {"parentUuid":"32073fe1-e077-4c19-9f38-a60310a7addc","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":67},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":20}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-04T20:59:15.201Z","uuid":"3436e079-c329-4f9c-bedd-633b53ef2492","toolUseID":"df9eaa72-eed9-4097-b3aa-c5634642441c","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 64 64 + {"parentUuid":"3436e079-c329-4f9c-bedd-633b53ef2492","isSidechain":false,"type":"system","subtype":"away_summary","content":"We're outlining your blog post about the ircd-to-Rust vibecoding experiment.

What should I add to match your vibe?\n\n# My vibecoding experiment of an IRC daemon in Rust\n\nOutline:\n\n* Early June I decided to see how effectively Claude Opus could port an IRC daemon to Rust, then use that Rust version of the program as a correctness oracle to write a new IRC daemon in idiomatic Rust. \n * Software rewrites in other languages fail. This is a known fact. Any time someone tells you that they're doing a big rewrite in Rust, they're going to fail. It is a matter of when, not if. \n * As codebases get bigger, more legacy behaviour and workarounds get ossified into place. This behaviour is lost in rewrites and ends up making integration with third parties difficult or impossible. \n * The only exception to this is when you do a [Strangler Fig migration](https://martinfowler.com/bliki/StranglerFigApplication.html). This is when you start to modernize a codebase by gradually replacing codepaths with a new version of the same functionality. \n * I ended up wondering if existing off the shelf tools could be good enough to help rewrite a program in Rust by building detailed context about a C codebase by mechanically translating it to Rust and then using that to do a full greenfield rewrite. \n * This started out as an experimental offshoot of my [\"No way to prevent this\" say users of only language where this regularly happens](https://xeiaso.net/shitposts/no-way-to-prevent-this/memory-safety/CVE-2026-8461/) blogposts where I've been wondering if existing tools off the shelf are good enough to start moving our existing C code to Rust \n* The project I chose: ircnet/ircd \n * Why IRC? \n * IRC is a very simple protocol with an innumerable number of edge cases. \n * I have a long history of maintaining IRC server software. \n * This combination gives me a unique insight into how this protocol works and fails in practice. I'm kind of out of practice as I [stopped working on an IRCd in 2019](https://xeiaso.net/blog/deprecation-notice-elemental-ircd-2019-02-11/). \n * The exact IRC daemon I maintained was [way deep down the IRCd family tree](https://github.com/grawity/irc-docs/blob/d6941670a9013cfe81f0493ef1ddf28cfe6585b9/family-tree.txt#L69). I didn't want to pick it because it's based on [ircd-ratbox](https://ratbox.org/), which has a lot of complicated multi-platform support features that are frankly irrelevant in modern setups. \n * I wanted to pick an IRC daemon that was just complicated enough to exercise a lot of the issues you'd see in the real world, but not so complicated that the forest would be lost for the trees. \n* Ground rules \n * When I set out to do this, I set a few ground rules: \n * The existing C code is a [correctness oracle](https://en.wikipedia.org/wiki/Test_oracle), all changes will be compared against the correctness oracle to ensure that they are accurate. \n * I wanted to do as little action as possible and leave this running on a side monitor. \n * Eventually I had to move this from my tower to another machine because claude running tests could cause my tower to OOM, crashing my games \n * When converting the C to Rust, do the migration both outside-in and inside-out. \n * The main() function became Rust as early as possible, it mostly converted arguments/envvars/flags to the right things in C and kicked off the C

is landing well — the setup is now yours (the CVE series tie-in and the \"rewrites fail, it's when not if\" opener are exactly the right amount of spicy). But the outline currently ends where the interesting part begins: you have motivation and ground rules, and none of the thesis. Here's what I'd add, in your format so you can paste and reshape:\n\n**Add to Ground rules** (this is where the thesis gets planted):\n\n* The twist I didn't plan on: I ended up doing the strangler fig *twice*.\n * Stage one: strangle the C into a deliberately ugly, byte-faithful mechanical Rust port. Not idiomatic. Not nice. Its only job is to be provably equivalent to the C.\n * Stage two: use *that* as the correctness oracle for the daemon I actually wanted, written greenfield in idiomatic Rust (tokio, rustls, real config format).\n * The insight that made this cheap: an oracle doesn't have to be pretty, it just has to keep passing its tests. So the mechanical port never got cleaned up — cleaning it up would have been throwaway work. It got *deleted*.\n\n**New section: How do you trust code you're never going to read?**\n\n* The C codebase had zero tests. Turns out that's fine, because a program with a wire protocol *is* its own test suite — you just need to run two of them and diff the bytes.\n* The trick that carried the whole first half: `objcopy --prefix-symbols=cref_` over the entire reference C build, so the C version and the Rust version of the same function link into *one test binary* and get called side by side on the same inputs. Differential unit testing without mocks, stubs, or faith.\n* One level up: boot the reference ircd and the Rust ircd next to each other, drive scripted clients at both, byte-diff the wire output. If the bytes match, I don't need to read the diff.\n* This is the actual answer to \"how do you supervise an agent writing 160k lines\": you don't review the code, you design the verification structure and make the gates impossible to argue with.\n\n**New section: The walls** (keep it to the one vivid fact, per your forest-for-trees rule):\n\n* Stable Rust cannot define an `extern \"C\"` variadic function. Full stop. `sendto_one(to, fmt, ...)` and its ~25 siblings had to stay as tiny C trampolines until the very last day of the port — \"100% Rust\" was a final-phase goal by necessity, not choice.\n* (One sentence each, no more: structs with interior self-pointers, struct layout that shifts under config `#define`s, a partial-allocation trick where remote clients only get the front half of the struct.)\n\n**New section: Managing the agent** (the part your readers most want and other posts do worst):\n\n* Decisions get locked up front and written down, or the model re-litigates them forever. \"Faithful port first, idiomatic later\" was a rule, not a vibe.\n* The single most important rule I wrote: *if the oracle supports something and the new daemon doesn't, that's a bug to close, not a divergence to document.* Agents would much rather write a paragraph explaining a gap than fix it. You close that off structurally, not by watching.\n* Persistent memory files as the index of hard-won facts — the model rediscovering the same bindgen footgun three times is how you burn a weekend.\n* Your OOM anecdote lives here and it's good — keep it. Concrete cost of \"leave it running on a side monitor.\"\n\n**New section: Killing the middleman**\n\n* June 13: parity reached, so the mechanical port — the verified thing the whole first phase produced — got deleted from the workspace. On purpose. It was always scaffolding.\n* Then it stopped being a migration: the new daemon grew things the 1997 C never had (IRCv3, SASL, TLS server links, SQLite chat history) — compress this to two sentences, it's a changelog otherwise.\n* It runs a real multi-server network now. Only include this if you tell one specific prod-only bug story (you have a cross-server desync one); \"it's in production\" as a bare claim is filler.\n\n**Closing caveat (this is what makes the whole post credible):**\n\n* IRC was a rigged choice: line-based wire protocol, trivially byte-diffable. The method generalizes exactly as far as your ability to find a diffable behavioral surface for your legacy C. If your program's observable behavior is \"mutates a database and sends emails,\" your oracle is going to cost a lot more than mine did.\n\nOne edit to what you have: in the \"rewrites fail\" bullet, you set up strangler fig as the known exception — consider foreshadowing there (\"what I didn't expect is that I'd end up doing it twice, and the second fig would strangle the first\"). It turns the structural gimmick of the post into a hook in the first thirty seconds."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1173,"cache_read_input_tokens":61499,"output_tokens":2381,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1173,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":2381,"cache_read_input_tokens":61499,"cache_creation_input_tokens":1173,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1173},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cchk9qswdd6uKXk4dduEX","type":"assistant","uuid":"18b8768b-6e96-4582-b3fe-d0b47fbb0c3d","timestamp":"2026-07-04T21:42:24.251Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

that ported the 1997-era IRCnet ircd 2.11 C daemon to Rust via a strangler-fig migration (mechanical faithful port, differentially tested against the C as an oracle), then used the mechanical port as an oracle for a greenfield idiomatic daemon. The human is writing a blog post about the experiment and wants to know which stories buried in these notes are genuinely interesting to a technical audience.\n\nYour job: return a ranked list of candidate blog-post topics/anecdotes found in these files. For each: (1) the concrete story or technical detail, told specifically (names, numbers, mechanisms — not vague), (2) why it would interest a systems-programming reader who has already heard \"AI ported C to Rust\" a hundred times, (3) source file.

Here is my ranked list of blog-post candidates, filtered for a systems audience that's already tired of \"AI ported C to Rust.\"\n\n---\n\n## Tier 1 — the strongest stories\n\n**1. Freezing the clock froze the whole server (the counterintuitive determinism trap)**\nThe written test plan said the obvious thing: to make golden tests deterministic, `LD_PRELOAD` a shim overriding `time()`/`gettimeofday()` to a fixed value. Doing it *breaks the daemon entirely*. A frozen `time()` freezes the global `timeofday` (reset every loop iteration at `ircd.c:1250`), so the io_loop's scheduler never advances and **the listen socket is never serviced** — clients just hang, never accepted. The tell was in `strace`: `poll()` was only watching the resolver fd. The fix was the inverse of intuition: keep the *real* clock and mask the handful of time-bearing output tokens (numerics 242 uptime, 317 idle/signon, 391 time) in a canonicalizer instead. This is a great \"the fix for nondeterminism is NOT to remove time\" lede.\nSource: `p0-l2-golden-harness.md`\n\n**2. The oracle was garbage: two 1990s varargs bugs the reference C emits and the Rust doesn't**\nThe whole project trusts the C as an oracle — except in two STATS paths the C emits pure garbage and the Rust port is *correct*, which inverts the entire testing premise. (a) `report_myservers` (STATS m) prints an uninitialized peer sendq for a freshly-bursting link: `…recv 3544950785030750208kB sq…` vs Rust's `0kB sq`. (b) STATS t (`s_misc.c:1079`) formats three `u_int` (4-byte) counters `is_cklQ/is_ckly/is_cklno` with `%lu` (8-byte), so the still-C variadic `sendto_one` `va_arg`s 4 bytes of *adjacent call-frame garbage*: `281470681743360Sq/…` vs Rust's `0Sq`. A width-mismatch printf bug that's been latent since 1997, surfaced only because a byte-exact Rust twin existed to disagree with it. Forces the essay's best question: what do you do when your source-of-truth is provably wrong? (Answer: note it, don't \"fix\" the snapshot, defer to when the variadic sender is replaced.)\nSource: `p5-s2s-stats-flake.md`\n\n**3. Running two versions of the same program in one process via `objcopy` symbol renaming**\nThe L1 differential harness is genuinely clever and generalizes. To diff the Rust port against the C function-by-function *in the same test binary*, the build does `nm -g --defined-only` over the C objects → builds a rename map `&lt;sym&gt; → cref_&lt;sym&gt;` → `objcopy --redefine-syms` on a copy of each `.o` → `ar crDs` into `libcref.a`. Now `match` (Rust's `#[no_mangle]`) and `cref_match` (the C original) coexist at distinct addresses and you assert they agree over a corpus. ~450 symbols across 31 objects. The sharp-edge follow-ups are just as good: (a) `objcopy` only renames *global* symbols, so any `static` C function has no `cref_` twin and simply can't be L1-tested (hit on `lookup_confhost`, static in `s_conf.c`) — you fall back to a golden test of a caller; (b) an integration test made only of raw `extern` blocks references no Rust item, so rustc drops the rlib and *every* C symbol goes undefined at link — you need a `link_anchor()` that touches a real Rust item to pin the archive.\nSource: `p0c-l1-harness-constraints.md`, `l1-cref-static-symbol-limit.md`\n\n**4. The variadic wall: what stable Rust literally cannot do, and how it shaped the whole port**\nStable Rust cannot *define* an `extern \"C\"` variadic function. IRCnet's entire output layer is variadic `sendto_*`/`esendto_*`, and worse, `vsendpreprep` consumes `va_arg` *per recipient* while walking the member list — so there's no \"format once, hand a string to Rust\" reduction available. Consequence: ~25 sender trampolines stayed as C until the very last phase, and \"100% Rust\" was a stated end-goal, not a mid-migration property. The eventual rip-out has a subtle systems detail worth the post: they rejected `format!` for building wire lines because it routes through a UTF-8 `String` and is **lossy on arbitrary bytes** in kill/quit comments (→ byte-diff failures against the oracle). They built a `wire!` raw-byte line builder (`cstr_bytes`) so user content passes verbatim, later growing printf-faithful newtypes (`Hex08`, `Dec02`, `%p` via libc) to stay byte-identical.\nSource: `ircd-migration-hazards.md`, `p3-transport-format.md`, `p8-started.md`\n\n## Tier 2 — strong, more specialized\n\n**5. bindgen silently degrades structs to opaque byte-blobs — for two invisible reasons**\nFuture phases depend on `offset_of!` over 14 structs, and bindgen will quietly emit `pub struct X { _address: u8 }` (breaking every offset) under two non-obvious conditions. (a) bindgen defaults to **C++**, and these 1990s headers use `class` as a struct *field name* (`class_def.h:25`) and the `register` storage class — both C++ errors; clang's C++ error-recovery leaves the struct incomplete. Fix: force `-x c`. (b) bindgen 0.70 mishandles the libclang-22 AST for structs forward-declared as `typedef struct X Y;` (Client/User/Server/Channel…), picking the forward decl over the real definition; 0.72 fixes it. The diagnostic ritual — `grep -c 'pub _address: u8,'` should be 0 — plus a \"layout drift-net\" that emits bindgen's sizes/offsets as *compile-time* `const` assertions checked against a C compile of `offsetof`. Practical FFI war story for anyone bindgen-ing old C.\nSource: `p0b-bindgen-constraints.md`\n\n**6. The double strangler, and deliberately throwing away the \"make it idiomatic\" phase**\nThe meta-architecture is the interesting part: the C tree was the oracle for a faithful *mechanical* Rust port; then that verified port became the oracle for a from-scratch *idiomatic* daemon (`leveva`); then both got deleted at parity. The load-bearing decision (2026-06-08) was **retiring P9 entirely** — the phase that would have cleaned up the mechanical port in place (`MyMalloc`→`Box`, freelist→owned, `libc`→`std`). Rationale: \"an oracle only needs to keep building and passing its tests; it does not need to be idiomatic,\" and that crate is deleted at parity anyway, so polishing it earns nothing. A crisp argument about where refactoring effort is and isn't worth spending during a migration.\nSource: `leveva-pivot-p9-retired.md`, `p12-complete.md`\n\n**7. IRC's own flood protection sabotaged the test harness**\nA rich testing-determinism war story. The daemon's fake-lag (anti-flood penalty) throttle makes scripted golden tests flaky: the penalty clock runs ahead of wall-clock, the server *stops reading the socket*, and reads time out (60s vs 11s runs). Both the `client_packet` recvQ gate and the `read_packet` re-arm gate must be bypassed — disabling only one leaves the socket unread. The deeper follow-up is the best bit: a golden test failed *deterministically* 3/3, and the root cause was that three `NAMES` whole-table scans cost +4 penalty each at the harness's 50ms pacing → the client's command clock ran ~21s ahead of the 10s `MAX_PENALTY` → the serve loop *parked* that client's read arm. A separate case: polling `WHOIS` every 300ms to keep a connection alive tripped the &gt;60s excess-flood *kill*, closing the socket → `BrokenPipe` on the next write. The lesson (deterministic `read_until` \"no NNN\" panic = fakelag parking, not load) is a genuine debugging-taxonomy insight.\nSource: `test-fakelag-disabled.md`, `golden-read-until-timeout-flake.md`\n\n**8. 1990s memory micro-optimizations that make \"no moves\" a correctness requirement in Rust**\nTwo intertwined hazards. `aClient` has **interior self-pointers**: `make_client` sets `cptr-&gt;name = cptr-&gt;namebuf` (`list.c:121`), and `me` is a by-value global with `client = &amp;me`. Move or copy that struct by value in Rust and the self-pointer dangles — so it's raw-pointers-only, everywhere, and the idiomatic pass has to unwind it. Paired with the `CLIENT_REMOTE_SIZE` trick (`struct_def.h:577`): remote clients are deliberately allocated only `offsetof(aClient, count)` bytes to save memory, so touching the local-only tail of a struct when `from != self` is a straight out-of-bounds read. A concrete illustration of how a 30-year-old RAM-saving hack dictates the shape of the safe-Rust rewrite.\nSource: `ircd-migration-hazards.md`, `p2-data-lookup.md`\n\n## Tier 3 — good supporting anecdotes / sidebars\n\n**9. Port the compiled ABI, not the header — and replicate the bugs on purpose**\nFaithful-port discipline produced several sharp findings. `dbuf_copy` is declared in `dbuf_ext.h` but *commented out* in `dbuf.c` — no symbol, no callers, no `cref_` oracle; porting it would have invented behavior. Rule: match the compiled ABI (7 dbuf fns), not the header (8). Meanwhile `match()` has an always-active `MAX_ITERATIONS 512` DoS cap whose `#ifdef` guard is unconditionally true — the Rust *must* reproduce the `calls++ &gt; 512 → return 1` early-out. And `irc_memcmp` is reimplemented as a plain byte compare because only the *sign* of the result is contractually observed (test asserts `.signum()`). Good material on \"faithful\" being a precise, sometimes counterintuitive contract.\nSource: `p1-leaf-utils.md`\n\n**10. `static mut` globals race across cargo's parallel test threads (with a vivid symptom)**\nA whole class of test-isolation bugs: process-global `static mut` state (`me`, `local[]`, `highest_fd`, hash tables, an oper-flag conversion buffer) is one shared instance, and cargo runs `#[test]`s on parallel threads. The signature symptom is great copy: oper-flag letters scramble under load — `LKSClhdrRDeTqPpt` intermittently renders as `t`, or `-`→`K`. Diagnosis heuristic worth stating: *passes alone, fails in the suite = shared-global race*; fix is a file-level serializing `Mutex`. The L1 analogue of the L2 `PORT_LOCK`.\nSource: `p7-l1-shared-global-race.md`, `s-conf-oline-snap-flake.md`, `p2-data-lookup.md`\n\n**11. Char signedness and a dead-code linker failure — 1990s portability macros biting back**\nTwo same-day host-portability gotchas. `c_char` is `i8` on x86_64 but `u8` on aarch64, so an L1 test that declared its buffers `[0i8; 64]` only compiled on x86 (4× E0308 on aarch64); the fix is to always type C-char buffers as `c_char`. Separately, `support_diff` failed to *link* with `undefined reference to cref_irc_memcmp` — because `irc_memcmp` is wrapped in `#if defined(HAVE_MEMCMP) &amp;&amp; defined(MEMCMP_BROKEN)`, and configure decided this host's memcmp is fine (`MEMCMP_BROKEN` undefined), so the function is dead code with no symbol to rename. A nice illustration of configure-era conditional compilation surfacing as a modern Rust link error.\nSource: `s-user-umode-diff-broken.md`, `support-irc-memcmp-host-gated.md`\n\n**12. The standalone-server paradox in S2S testing**\nWeird-protocol-behavior sidebar. A lone server with one configured uplink is permanently *split* (`IsSplit()`), so a local client **cannot create** a `#` channel (`m_join:2591` → `ERR_UNAVAILRESOURCE`) — but the split guard sits inside `if(!chptr)`, so it *can* JOIN a channel that already exists. The workaround shaped the whole S2S test strategy: have the fake peer create the channel server-side via `NJOIN` (`get_channel(&amp;me, …, CREATE)`), then have the local client join it as an observer. Also notable: incremental remote joins use `NJOIN`, not `JOIN` — plain `JOIN` over S2S only ever means \"JOIN 0\"/part-all (`channel.c:2381`).\nSource: `p5-s2s-golden-harness.md`, `boot-golden-harness.md`\n\n---\n\n**Honorable mentions** (small, could be one-liners or sidebars, probably not their own post): `myncmp` does its end-of-string check *after* advancing pointers → OOB read on the empty string with n≥2, found just by reading the C carefully (`p0c`); `replies[]` had to be *dumped from the compiled oracle*, not text-extracted, because of `#if` config branches and an escaped `\\r\\n` at entry 384 that would CRLF-normalize away if pasted (`p3`); `alphabet_id[256]` is only 249-entry-initialized in C so indices 249–255 default to 0, reproduced verbatim (`p3`); DNS reverse-PTR lookup was disabled project-wide (`-DNO_DNS_LOOKUP`) because it was both nondeterministic *and* held registration across loop iterations (`p0-l2`); NUL-terminate fixtures before `strcpy` or you overrun `namebuf` into heap corruption (`p8` P8e).\n\nOne framing note for the human: items 1, 2, 3, 4, and 7 are the ones a jaded systems reader hasn't seen before — they're specific to *differentially testing a port* and to *1997 C's runtime behavior*, not to \"AI\" or \"Rust\" generically.

They built a `wire!` raw-byte line builder (`cstr_bytes`) so user content passes verbatim, later growing printf-faithful newtypes (`Hex08`, `Dec02`, `%p` via libc) to stay byte-identical.\nSource: `ircd-migration-hazards.md`, `p3-transport-format.md`, `p8-started.md`\n\n## Tier 2 — strong, more specialized\n\n**5. bindgen silently degrades structs to opaque byte-blobs — for two invisible reasons**\nFuture phases depend on `offset_of!` over 14 structs, and bindgen will quietly emit `pub struct X { _address: u8 }` (breaking every offset) under two non-obvious conditions. (a) bindgen defaults to **C++**, and these 1990s headers use `class` as a struct *field name* (`class_def.h:25`) and the `register` storage class — both C++ errors; clang's C++ error-recovery leaves the struct incomplete. Fix: force `-x c`. (b) bindgen 0.70 mishandles the libclang-22 AST for structs forward-declared as `typedef struct X Y;` (Client/User/Server/Channel…), picking the forward decl over the real definition; 0.72 fixes it. The diagnostic ritual — `grep -c 'pub _address: u8,'` should be 0 — plus a \"layout drift-net\" that emits bindgen's sizes/offsets as *compile-time* `const` assertions checked against a C compile of `offsetof`. Practical FFI war story for anyone bindgen-ing old C.\nSource: `p0b-bindgen-constraints.md`\n\n**6. The double strangler, and deliberately throwing away the \"make it idiomatic\" phase**\nThe meta-architecture is the interesting part: the C tree was the oracle for a faithful *mechanical* Rust port; then that verified port became the oracle for a from-scratch *idiomatic* daemon (`leveva`); then both got deleted at parity. The load-bearing decision (2026-06-08) was **retiring P9 entirely** — the phase that would have cleaned up the mechanical port in place (`MyMalloc`→`Box`, freelist→owned, `libc`→`std`). Rationale: \"an oracle only needs to keep building and passing its tests; it does not need to be idiomatic,\" and that crate is deleted at parity anyway, so polishing it earns nothing. A crisp argument about where refactoring effort is and isn't worth spending during a migration.\nSource: `leveva-pivot-p9-retired.md`, `p12-complete.md`\n\n**7. IRC's own flood protection sabotaged the test harness**\nA rich testing-determinism war story. The daemon's fake-lag (anti-flood penalty) throttle makes scripted golden tests flaky: the penalty clock runs ahead of wall-clock, the server *stops reading the socket*, and reads time out (60s vs 11s runs). Both the `client_packet` recvQ gate and the `read_packet` re-arm gate must be bypassed — disabling only one leaves the socket unread. The deeper follow-up is the best bit: a golden test failed *deterministically* 3/3, and the root cause was that three `NAMES` whole-table scans cost +4 penalty each at the harness's 50ms pacing → the client's command clock ran ~21s ahead of the 10s `MAX_PENALTY` → the serve loop *parked* that client's read arm. A separate case: polling `WHOIS` every 300ms to keep a connection alive tripped the &gt;60s excess-flood *kill*, closing the socket → `BrokenPipe` on the next write. The lesson (deterministic `read_until` \"no NNN\" panic = fakelag parking, not load) is a genuine debugging-taxonomy insight.\nSource: `test-fakelag-disabled.md`, `golden-read-until-timeout-flake.md`\n\n**8. 1990s memory micro-optimizations that make \"no moves\" a correctness requirement in Rust**\nTwo intertwined hazards. `aClient` has **interior self-pointers**: `make_client` sets `cptr-&gt;name = cptr-&gt;namebuf` (`list.c:121`), and `me` is a by-value global with `client = &amp;me`. Move or copy that struct by value in Rust and the self-pointer dangles — so it's raw-pointers-only, everywhere, and the idiomatic pass has to unwind it. Paired with the `CLIENT_REMOTE_SIZE` trick (`struct_def.h:577`): remote clients are deliberately allocated only `offsetof(aClient, count)` bytes to save memory, so touching the local-only tail of a struct when `from != self` is a straight out-of-bounds read. A concrete illustration of how a 30-year-old RAM-saving hack dictates the shape of the safe-Rust rewrite.\nSource: `ircd-migration-hazards.md`, `p2-data-lookup.md`\n\n## Tier 3 — good supporting anecdotes / sidebars\n\n**9. Port the compiled ABI, not the header — and replicate the bugs on purpose**\nFaithful-port discipline produced several sharp findings. `dbuf_copy` is declared in `dbuf_ext.h` but *commented out* in `dbuf.c` — no symbol, no callers, no `cref_` oracle; porting it would have invented behavior. Rule: match the compiled ABI (7 dbuf fns), not the header (8). Meanwhile `match()` has an always-active `MAX_ITERATIONS 512` DoS cap whose `#ifdef` guard is unconditionally true — the Rust *must* reproduce the `calls++ &gt; 512 → return 1` early-out. And `irc_memcmp` is reimplemented as a plain byte compare because only the *sign* of the result is contractually observed (test asserts `.signum()`). Good material on \"faithful\" being a precise, sometimes counterintuitive contract.\nSource: `p1-leaf-utils.md`\n\n**10. `static mut` globals race across cargo's parallel test threads (with a vivid symptom)**\nA whole class of test-isolation bugs: process-global `static mut` state (`me`, `local[]`, `highest_fd`, hash tables, an oper-flag conversion buffer) is one shared instance, and cargo runs `#[test]`s on parallel threads. The signature symptom is great copy: oper-flag letters scramble under load — `LKSClhdrRDeTqPpt` intermittently renders as `t`, or `-`→`K`. Diagnosis heuristic worth stating: *passes alone, fails in the suite = shared-global race*; fix is a file-level serializing `Mutex`. The L1 analogue of the L2 `PORT_LOCK`.\nSource: `p7-l1-shared-global-race.md`, `s-conf-oline-snap-flake.md`, `p2-data-lookup.md`\n\n**11. Char signedness and a dead-code linker failure — 1990s portability macros biting back**\nTwo same-day host-portability gotchas. `c_char` is `i8` on x86_64 but `u8` on aarch64, so an L1 test that declared its buffers `[0i8; 64]` only compiled on x86 (4× E0308 on aarch64); the fix is to always type C-char buffers as `c_char`. Separately, `support_diff` failed to *link* with `undefined reference to cref_irc_memcmp` — because `irc_memcmp` is wrapped in `#if defined(HAVE_MEMCMP) &amp;&amp; defined(MEMCMP_BROKEN)`, and configure decided this host's memcmp is fine (`MEMCMP_BROKEN` undefined), so the function is dead code with no symbol to rename. A nice illustration of configure-era conditional compilation surfacing as a modern Rust link error.\nSource: `s-user-umode-diff-broken.md`, `support-irc-memcmp-host-gated.md`\n\n**12. The standalone-server paradox in S2S testing**\nWeird-protocol-behavior sidebar. A lone server with one configured uplink is permanently *split* (`IsSplit()`), so a local client **cannot create** a `#` channel (`m_join:2591` → `ERR_UNAVAILRESOURCE`) — but the split guard sits inside `if(!chptr)`, so it *can* JOIN a channel that already exists. The workaround shaped the whole S2S test strategy: have the fake peer create the channel server-side via `NJOIN` (`get_channel(&amp;me, …, CREATE)`), then have the local client join it as an observer. Also notable: incremental remote joins use `NJOIN`, not `JOIN` — plain `JOIN` over S2S only ever means \"JOIN 0\"/part-all (`channel.c:2381`).\nSource: `p5-s2s-golden-harness.md`, `boot-golden-harness.md`\n\n---\n\n**Honorable mentions** (small, could be one-liners or sidebars, probably not their own post): `myncmp` does its end-of-string check *after* advancing pointers → OOB read on the empty string with n≥2, found just by reading the C carefully (`p0c`); `replies[]` had to be *dumped from the compiled oracle*, not text-extracted, because of `#if` config branches and an escaped `\\r\\n` at entry 384 that would CRLF-normalize away if pasted (`p3`); `alphabet_id[256]` is only 249-entry-initialized in C so indices 249–255 default to 0, reproduced verbatim (`p3`); DNS reverse-PTR lookup was disabled project-wide (`-DNO_DNS_LOOKUP`) because it was both nondeterministic *and* held registration across loop iterations (`p0-l2`); NUL-terminate fixtures before `strcpy` or you overrun `namebuf` into heap corruption (`p8` P8e).\n\nOne framing note for the human: items 1, 2, 3, 4, and 7 are the ones a jaded systems reader hasn't seen before — they're specific to *differentially testing a port* and to *1997 C's runtime behavior*, not to \"AI\" or \"Rust\" generically.

Here is my ranked list of blog-post candidates, told with the concrete specifics a systems reader would want.\n\n---\n\n## Ranked candidate topics\n\n### 1. The channel-timestamp merge fight that silently stripped ops from everyone\n**Story:** On the live network, two servers disagreed about a channel's creation timestamp because a server learning a channel via a join re-clocked `created_at` with its own local clock — so the two nodes differed by exactly the propagation latency. The TS6-style `CHANTS` arbitration (\"oldest timestamp wins, younger side's chanops get deopped\") then deopped whichever server *learned of the channel later*. Across recreate/relink flaps this stripped ops from **every** side. Observed in production as `#leveva` sitting at `+nt` with zero ops and `-o Xe`. A later variant (slice 215): upgrading one server to v0.1.0 and relinking made it strip channel modes that should have survived a merge — `#xe` lost `-oo`, `-R *`, and a peer's manual `+ooo` 40s later. The fix required carrying the channel TS as a wire parameter on the NJOIN join-propagation verb, and reasoning carefully about *which* path (burst vs live) owns arbitration so the fix for one didn't defeat the other.\n**Why it's interesting:** This is a textbook distributed-consensus failure — clock skew feeding a \"lowest timestamp wins\" tiebreak that then mutates authority state — playing out in a real netsplit/merge on a running network, not a whiteboard. The subtlety that fixing the *live* path left the *burst* path broken (same bug, two code paths) is exactly the kind of thing that bites real distributed systems.\n**Source:** `leveva-live-join-njoin.md`\n\n### 2. The bare UID in NAMES: diagnosing a cross-server identity desync by dialing each node directly\n**Story:** On the production network a channel member showed up as a raw UID (`4LTKAAAAF`) instead of a nick, but only on some servers. Root cause (slice 86): the S2S user-introduction verb `UNICK` was emitted **only** in the link-time burst. A client who registered *after* a link was already up was never announced to the peer — every other relay (JOIN/PART/PRIVMSG/QUIT) fired, so the peer received actions from a UID it had no record for, delivered them with the raw UID prefix, and silently dropped the user from remote NAMES (the reply builder does `filter_map(record_of)`). The lesson: every outbound S2S relay needs *both* a live path and a burst path, and the introduction was the one verb that only had the burst path. The diagnostic technique is itself blog-worthy: since the front door (`irc.xeserv.us:6667`) load-balances you onto an arbitrary member, you reach one specific server directly at `&lt;servername&gt;.alrest.xeserv.us` and compare the same channel across servers at different hop distances to localize exactly where nick resolution breaks.\n**Why it's interesting:** A genuine \"it works on my machine / works within one hop\" distributed bug, plus a concrete field-debugging methodology for a multi-server system where the nodes disagree.\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`, `leveva-prod-shadownet-per-server-probe.md`\n\n### 3. A bare unknown server command is *fatal* in 1997 IRCnet — so every extension has to be tunneled\n**Story:** Sending a bare `:sid CAPAB …` (a new leveva capability-negotiation verb) to the faithfully-ported C oracle makes it reply `SQUIT … :Success` + `ERROR :Closing Link` and drop the link. But `ENCAP` is routed to `m_nop` and tolerated. This was verified against the in-process 1997-lineage oracle. The consequence became an architectural law: **every leveva-native S2S extension verb must ride inside `ENCAP`** to keep a strict IRCnet peer alive (CAPAB, REDACT, CHGHOST, CERTFP, channel-TS, user-TS, METADATA, KNOCK, RESV, KLINE all became `ENCAP *`-wrapped), while real IRCnet verbs (AWAY, INVITE, WALLOPS, KILL) stay first-class. Timestamps ride `ENCAP` in unix nanoseconds — which a real IRCnet oracle simply routes to `m_nop` and ignores, so the same bytes are safe on both.\n**Why it's interesting:** Protocol archaeology with teeth — a design constraint on a modern daemon dictated by the crash behavior of 27-year-old C, *discovered empirically by running that C as a test oracle*. It's a clean illustration of \"extension tunneling to stay wire-compatible with something unforgiving,\" like TLS extensions or IP options.\n**Source:** `leveva-s2s-peer-caps.md`, `leveva-s2s-notify-propagation.md`, `leveva-ts-and-link-fixes-131-133.md`\n\n### 4. The memory leak that wasn't: measuring instead of assuming\n**Story:** A user reported a memory leak. Rather than inspecting internal stores, the demand was for real measurement: boot real daemons, drive load with a Python socket harness, sample `/proc/&lt;pid&gt;/VmRSS`. Result — **no unbounded leak anywhere**: connection churn flat at 16764 KB from 11k→30k connections; unique-channel churn flat (empty channels reaped on part); S2S kill/relink plateaus (subtree reclaimed); true half-open (SIGSTOP the peer) reaps at t+4s under a 2s ping-freq. The perceived \"leak\" was two things: (1) the half-open keepalive works, but at the default 90s ping-freq it takes 180s, so anyone watching for under ~3 minutes sees remote users persist (working-as-designed-but-slow), and (2) the introduction-ghost state from bug #2 above. Bonus test-harness gotcha: under `ping-freq 2`, passive Python clients that don't answer PING get ping-timed-out in ~4s and vanish on their own, confounding the measurement.\n**Why it's interesting:** A crisp \"your intuition about the bug is the bug\" story plus an honest, reproducible measurement methodology — the opposite of the usual hand-wavy \"we think it leaks.\"\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`\n\n### 5. Building a 1997 C daemon as an in-process differential oracle — and the RFC-vs-reality verdicts it produced\n**Story:** The core testing rig boots a mechanically-ported Rust copy of 1997 IRCnet ircd *in-process*, drives both it and the greenfield daemon over real loopback TCP, and diffs their responses reduced to a skeleton of 3-digit numeric reply codes. Over ~20 command clusters this produced surprising verdicts. The best: for `PRIVMSG`/`NOTICE` with missing params, the oracle emits `461 ERR_NEEDMOREPARAMS` — because its *parser* enforces min-params=2 before the handler ever runs, so the C code never emits the RFC-specified `411`/`412` at all. The IRCnet daemon quietly diverges from the RFC it nominally implements, and the greenfield daemon had to be made *bug-for-bug* compatible. This crystallized a governance rule: \"if the oracle supports something the new daemon doesn't, that's a bug — close it,\" reserved against the opposite cases where the *new* daemon is RFC-correct and the oracle is quirky (bare `WHO` → the oracle 461s where RFC 2812 says list; second `+k` → 467 `ERR_KEYSET`; LIST's obsolete leading `321`).\n**Why it's interesting:** Differential testing against a legacy implementation as ground truth, and the philosophical knot of \"which one is *right* when the spec, the incumbent, and the newcomer all disagree?\" That's a real question in any clean-room reimplementation (browsers, SQL engines, compilers).\n**Source:** `leveva-native-oracle-harness.md`\n\n### 6. A property test that surfaced a genuine IRCv3 wire-format ambiguity (the lone `+`)\n**Story:** A SASL chunking round-trip property test flaked on any payload of length ≡ 1 (mod 400) ending in `+` (minimal repro: the bare string `\"+\"`). The initial \"exact-multiple-of-400\" guess was wrong — the real cause is that `AUTHENTICATE +` is *reserved* as the IRCv3 empty-payload sentinel, so a data chunk equal to the bare string `+` is **unrepresentable on the wire**, full stop. It's a genuine spec ambiguity, unfixable in the chunker (a non-final chunk must be exactly 400 chars — that length *is* the \"more follows\" signal), and unreachable for valid input (base64 length is always a multiple of 4, so a final chunk is never length 1). The fix was not to touch the chunker but to document the representability contract and tighten the fuzz domain to the real base64 alphabet — plus a test that pins the exact swallowed-`+` boundary.\n**Why it's interesting:** Fuzzing found a corner of the *specification*, not a bug in the code — and the correct response was to prove the property was impossible rather than \"fix\" it. A great cautionary tale about over-broad generators asserting impossible invariants.\n**Source:** `leveva-sasl-chunking-proptest-flake.md`\n\n### 7. Why a lone IRCnet server refuses to create a channel — the `is_split` burst-symmetry trap\n**Story:** Writing a differential test for the S2S burst revealed deep C behavior: a lone protocol-mode oracle boots with `iconf.split=1` and never clears it (its `split_minservers`/`minusers` are unconfigured at -1), so it is permanently `is_split()`, and a split IRCnet server *refuses to create a `#` channel*. Therefore a local channel can never appear in that server's outbound burst — burst symmetry could only be tested by seeding a local *user*, and NJOIN agreement had to be proven by having a peer burst a channel first, then joining the now-existing channel locally (so the non-null channel pointer skips the split-create block). Related archaeology: the PASS version token must be the exact IRCnet patchlevel `0211030000` or `get_version` rejects it as `SV_OLD`.\n**Why it's interesting:** A pile of load-bearing, undocumented legacy invariants that only surface when you try to make two implementations agree byte-for-byte — the reverse-engineering texture that makes reimplementation hard.\n**Source:** `leveva-native-oracle-harness.md`\n\n### 8. The maintainer overruling the AI's \"documented divergence\" on TS6 correctness\n**Story:** The agent had shipped a deliberate divergence from TS6: on a channel-merge loss it kept the loser's `+R` reop list unioned in (rather than wiping it with the bans/except/invex masks), with a plausible rationale (\"benign for the native `+R`, lets the inline reop restore the loser's members\"). The human overruled it as a **hard rule**: on a merge loss the loser drops *all* modes including list masks and adopts the winner's — no exceptions, no deferral. That forced a real restructuring: the reop enforcement could no longer read the loser's own (now-wiped) `+R` list, so it had to be rebuilt as an end-of-burst sweep that fires *after* the winner's `+R` masks arrive in burst order.\n**Why it's interesting:** A concrete instance of an AI making a reasonable-sounding local optimization that violated a global correctness invariant, and a human catching it — the human/AI design-authority tension made specific, on a genuine distributed-consistency rule (TS6).\n**Source:** `leveva-ts6-reop-must-wipe.md`, `leveva-live-join-njoin.md`\n\n### 9. Deliberate heresies against 30-year-old IRC tradition\n**Story:** Three considered breaks with IRC orthodoxy, each with a real rationale. (1) **UTF-8-only:** invalid UTF-8 in a client frame is rejected at the single byte→message parse boundary (mapped to an IRCv3 `INVALID_UTF8` FAIL) rather than lossy-decoded into U+FFFD as the C daemon does — enforced at parse so it \"transitively proves\" every downstream consumer is UTF-8-safe without re-checking, because a parsed message's fields are `String`. (2) **2048-grapheme lines** instead of the sacred 512-byte limit — measured in UAX-#29 grapheme clusters (not bytes), advertised as `LINELEN=2048`, with a framer DoS ceiling of 64 bytes/grapheme (covers ZWJ emoji families). (3) **Port-based client/server routing:** the daemon decides client-vs-server link by the *listener's* `server-only` flag, deliberately *not* by content-sniffing the PASS/SERVER handshake the way IRCnet does on a shared port — a cleaner separation, explicitly chosen and defended against \"fixing\" it back.\n**Why it's interesting:** Opinionated modernization of a legacy wire protocol, with the tradeoffs named (grapheme vs byte limits, parse-boundary type-safety as a security argument). Systems readers love \"we broke compatibility here, on purpose, and here's why.\"\n**Source:** `leveva-utf8-only-parse-boundary.md`, `leveva-linelen-2048-graphemes.md`, `leveva-s2s-port-based-routing.md`\n\n### 10. Porting a 1997 \"fakelag\" penalty clock — and finding dead privileges waiting for it\n**Story:** The flood-protection port was triggered by a smell: two operator privileges, `CanFlood` and `NoPenalty`, were parsed from config blocks but **read nowhere** in the codebase — dead flags waiting for a system that \"appeared in no progress log.\" The original algorithm was recovered from C git history: each command charges `since += 1 + len/100`; the clock idle-decays to real time so only a faster-than-1-cmd/sec client accumulates penalty; beyond a 10s ceiling (\"fakelag\") the server *delays* the connection's next read rather than disconnecting, pacing a flooder's input toward 1 cmd/sec while its fan-out and keepalive keep flowing; a hard kill fires only past a recvQ threshold. The delay half was reimplemented as a tokio `sleep_until` wrapped around the read arm of the connection's `select!`, throttling *input* only.\n**Why it's interesting:** Reverse-engineering an anti-abuse rate-limiter from a legacy codebase, the \"dead config field points at a missing feature\" detective beat, and a neat idiomatic-async reimplementation of a mechanism the C daemon achieved by stalling its recvQ drain.\n**Source:** `leveva-flood-penalty.md`\n\n### 11. Property tests that hand-copy a lookup table and flake stochastically forever after\n**Story:** A recurring, subtle testing failure mode: several property tests re-encoded an *assumption* about a command table instead of calling the real function — a hand-copied list of recognized `STATS` selector letters, an assumed flat cost-of-1 for flood penalties, an assumption that server-info verbs answer locally. When a later change grew the underlying table (a new STATS letter, a `WHO`/`LIST` flood surcharge of +4/+5, or a `hunt_server &lt;target&gt;` argument that short-circuits to `402`), the test would fail **only on unlucky random seeds** — passing in a single-file run and surfacing days later as an \"unrelated\" red in the full suite. The lesson: assert against the real function (`command_penalty`, the actual dispatcher), never a copy, and run the *whole* suite because the failing seed is random.\n**Why it's interesting:** A precise, reusable articulation of a property-testing anti-pattern (the model drifting out of sync with the implementation) and why it produces the worst kind of flake — non-local, non-deterministic, and misattributed.\n**Source:** `leveva-proptest-model-staleness.md`, `leveva-hunt-server-proptest-hazard.md`\n\n### 12. The auth subprocess that existed only to protect a single-threaded event loop\n**Story:** IRCnet's `iauth` ran as a separate child process talking a `&lt;id&gt; &lt;category&gt; &lt;info&gt;` pipe protocol to the main daemon. The reason was purely architectural: the C ircd is a single-threaded select/poll loop, and blocking DNS/ident/proxy-probe I/O had to be exiled to another process to keep the loop responsive. Under tokio that entire motivation evaporates — so the whole separate-process + pipe design was dropped and auth folded back into the daemon as native async modules (ident runs concurrently with the NICK/USER handshake, verdict stashed in the session so either arrival order works). A planned intermediate \"spawn it over a socketpair\" step was skipped as throwaway.\n**Why it's interesting:** A clean case of an architecture that existed *solely* as a workaround for a concurrency model, and what happens to it when the concurrency model changes — the kind of \"why does this weird boundary exist\" story that generalizes far beyond IRC.\n**Source:** `iauth-subsumed-into-leveva.md`\n\n---\n\n**Honorable mentions** (usable as supporting color, not full posts): the network-wide `msgid`/`@time` \"introducing-server-assigns, never re-mint\" model for cross-server message identity; the two harness gotchas where dropping a client handle silently reaps its user via EOF, and a fixture's per-IP CIDR connection cap (`10.2` = 2 clients/32) that broke any test opening a 3rd client; and the UNICK/NJOIN-vs-SJOIN \"divergence\" that turned out to be the agent confusing IRCnet's protocol lineage with Undernet/TS6, caught by an adversarial design reviewer and corrected to full agreement (`leveva-native-oracle-harness.md`).</result>\n<usage><subagent_tokens>104056</subagent_tokens><tool_uses>25</tool_uses><duration_ms>169410</duration_ms></usage>\n</task-notification>"} 109 109 + {"type":"queue-operation","operation":"dequeue","timestamp":"2026-07-04T21:46:31.203Z","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 110 110 + {"parentUuid":"669c050b-d0d7-4fb9-8add-5289964a6b7b","isSidechain":false,"promptId":"40d1bb90-b311-46b3-b52e-b124b7f031b8","type":"user","message":{"role":"user","content":"<task-notification>\n<task-id>ab6c910c34df5e720</task-id>\n<tool-use-id>toolu_01NLBCCA1k94hkWmj2AaxYdp</tool-use-id>\n<output-file>/tmp/claude-1000/-home-xe-Code-xeiaso-net-ircd-rs/5afb6f54-a28b-4d54-abb4-024e2406a27c/tasks/ab6c910c34df5e720.output</output-file>\n<status>completed</status>\n<summary>Agent \"Mine leveva feature-era memories\" finished</summary>\n<note>A task-notification fires each time this agent stops with no live background children of its own.

Here is my ranked list of blog-post candidates, told with the concrete specifics a systems reader would want.\n\n---\n\n## Ranked candidate topics\n\n### 1. The channel-timestamp merge fight that silently stripped ops from everyone\n**Story:** On the live network, two servers disagreed about a channel's creation timestamp because a server learning a channel via a join re-clocked `created_at` with its own local clock — so the two nodes differed by exactly the propagation latency. The TS6-style `CHANTS` arbitration (\"oldest timestamp wins, younger side's chanops get deopped\") then deopped whichever server *learned of the channel later*. Across recreate/relink flaps this stripped ops from **every** side. Observed in production as `#leveva` sitting at `+nt` with zero ops and `-o Xe`. A later variant (slice 215): upgrading one server to v0.1.0 and relinking made it strip channel modes that should have survived a merge — `#xe` lost `-oo`, `-R *`, and a peer's manual `+ooo` 40s later. The fix required carrying the channel TS as a wire parameter on the NJOIN join-propagation verb, and reasoning carefully about *which* path (burst vs live) owns arbitration so the fix for one didn't defeat the other.\n**Why it's interesting:** This is a textbook distributed-consensus failure — clock skew feeding a \"lowest timestamp wins\" tiebreak that then mutates authority state — playing out in a real netsplit/merge on a running network, not a whiteboard. The subtlety that fixing the *live* path left the *burst* path broken (same bug, two code paths) is exactly the kind of thing that bites real distributed systems.\n**Source:** `leveva-live-join-njoin.md`\n\n### 2. The bare UID in NAMES: diagnosing a cross-server identity desync by dialing each node directly\n**Story:** On the production network a channel member showed up as a raw UID (`4LTKAAAAF`) instead of a nick, but only on some servers. Root cause (slice 86): the S2S user-introduction verb `UNICK` was emitted **only** in the link-time burst. A client who registered *after* a link was already up was never announced to the peer — every other relay (JOIN/PART/PRIVMSG/QUIT) fired, so the peer received actions from a UID it had no record for, delivered them with the raw UID prefix, and silently dropped the user from remote NAMES (the reply builder does `filter_map(record_of)`). The lesson: every outbound S2S relay needs *both* a live path and a burst path, and the introduction was the one verb that only had the burst path. The diagnostic technique is itself blog-worthy: since the front door (`irc.xeserv.us:6667`) load-balances you onto an arbitrary member, you reach one specific server directly at `&lt;servername&gt;.alrest.xeserv.us` and compare the same channel across servers at different hop distances to localize exactly where nick resolution breaks.\n**Why it's interesting:** A genuine \"it works on my machine / works within one hop\" distributed bug, plus a concrete field-debugging methodology for a multi-server system where the nodes disagree.\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`, `leveva-prod-shadownet-per-server-probe.md`\n\n### 3. A bare unknown server command is *fatal* in 1997 IRCnet — so every extension has to be tunneled\n**Story:** Sending a bare `:sid CAPAB …` (a new leveva capability-negotiation verb) to the faithfully-ported C oracle makes it reply `SQUIT … :Success` + `ERROR :Closing Link` and drop the link. But `ENCAP` is routed to `m_nop` and tolerated. This was verified against the in-process 1997-lineage oracle. The consequence became an architectural law: **every leveva-native S2S extension verb must ride inside `ENCAP`** to keep a strict IRCnet peer alive (CAPAB, REDACT, CHGHOST, CERTFP, channel-TS, user-TS, METADATA, KNOCK, RESV, KLINE all became `ENCAP *`-wrapped), while real IRCnet verbs (AWAY, INVITE, WALLOPS, KILL) stay first-class. Timestamps ride `ENCAP` in unix nanoseconds — which a real IRCnet oracle simply routes to `m_nop` and ignores, so the same bytes are safe on both.\n**Why it's interesting:** Protocol archaeology with teeth — a design constraint on a modern daemon dictated by the crash behavior of 27-year-old C, *discovered empirically by running that C as a test oracle*. It's a clean illustration of \"extension tunneling to stay wire-compatible with something unforgiving,\" like TLS extensions or IP options.\n**Source:** `leveva-s2s-peer-caps.md`, `leveva-s2s-notify-propagation.md`, `leveva-ts-and-link-fixes-131-133.md`\n\n### 4. The memory leak that wasn't: measuring instead of assuming\n**Story:** A user reported a memory leak. Rather than inspecting internal stores, the demand was for real measurement: boot real daemons, drive load with a Python socket harness, sample `/proc/&lt;pid&gt;/VmRSS`. Result — **no unbounded leak anywhere**: connection churn flat at 16764 KB from 11k→30k connections; unique-channel churn flat (empty channels reaped on part); S2S kill/relink plateaus (subtree reclaimed); true half-open (SIGSTOP the peer) reaps at t+4s under a 2s ping-freq. The perceived \"leak\" was two things: (1) the half-open keepalive works, but at the default 90s ping-freq it takes 180s, so anyone watching for under ~3 minutes sees remote users persist (working-as-designed-but-slow), and (2) the introduction-ghost state from bug #2 above. Bonus test-harness gotcha: under `ping-freq 2`, passive Python clients that don't answer PING get ping-timed-out in ~4s and vanish on their own, confounding the measurement.\n**Why it's interesting:** A crisp \"your intuition about the bug is the bug\" story plus an honest, reproducible measurement methodology — the opposite of the usual hand-wavy \"we think it leaks.\"\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`\n\n### 5. Building a 1997 C daemon as an in-process differential oracle — and the RFC-vs-reality verdicts it produced\n**Story:** The core testing rig boots a mechanically-ported Rust copy of 1997 IRCnet ircd *in-process*, drives both it and the greenfield daemon over real loopback TCP, and diffs their responses reduced to a skeleton of 3-digit numeric reply codes. Over ~20 command clusters this produced surprising verdicts. The best: for `PRIVMSG`/`NOTICE` with missing params, the oracle emits `461 ERR_NEEDMOREPARAMS` — because its *parser* enforces min-params=2 before the handler ever runs, so the C code never emits the RFC-specified `411`/`412` at all. The IRCnet daemon quietly diverges from the RFC it nominally implements, and the greenfield daemon had to be made *bug-for-bug* compatible. This crystallized a governance rule: \"if the oracle supports something the new daemon doesn't, that's a bug — close it,\" reserved against the opposite cases where the *new* daemon is RFC-correct and the oracle is quirky (bare `WHO` → the oracle 461s where RFC 2812 says list; second `+k` → 467 `ERR_KEYSET`; LIST's obsolete leading `321`).\n**Why it's interesting:** Differential testing against a legacy implementation as ground truth, and the philosophical knot of \"which one is *right* when the spec, the incumbent, and the newcomer all disagree?\" That's a real question in any clean-room reimplementation (browsers, SQL engines, compilers).\n**Source:** `leveva-native-oracle-harness.md`\n\n### 6. A property test that surfaced a genuine IRCv3 wire-format ambiguity (the lone `+`)\n**Story:** A SASL chunking round-trip property test flaked on any payload of length ≡ 1 (mod 400) ending in `+` (minimal repro: the bare string `\"+\"`). The initial \"exact-multiple-of-400\" guess was wrong — the real cause is that `AUTHENTICATE +` is *reserved* as the IRCv3 empty-payload sentinel, so a data chunk equal to the bare string `+` is **unrepresentable on the wire**, full stop. It's a genuine spec ambiguity, unfixable in the chunker (a non-final chunk must be exactly 400 chars — that length *is* the \"more follows\" signal), and unreachable for valid input (base64 length is always a multiple of 4, so a final chunk is never length 1). The fix was not to touch the chunker but to document the representability contract and tighten the fuzz domain to the real base64 alphabet — plus a test that pins the exact swallowed-`+` boundary.\n**Why it's interesting:** Fuzzing found a corner of the *specification*, not a bug in the code — and the correct response was to prove the property was impossible rather than \"fix\" it. A great cautionary tale about over-broad generators asserting impossible invariants.\n**Source:** `leveva-sasl-chunking-proptest-flake.md`\n\n### 7. Why a lone IRCnet server refuses to create a channel — the `is_split` burst-symmetry trap\n**Story:** Writing a differential test for the S2S burst revealed deep C behavior: a lone protocol-mode oracle boots with `iconf.split=1` and never clears it (its `split_minservers`/`minusers` are unconfigured at -1), so it is permanently `is_split()`, and a split IRCnet server *refuses to create a `#` channel*.

Related archaeology: the PASS version token must be the exact IRCnet patchlevel `0211030000` or `get_version` rejects it as `SV_OLD`.\n**Why it's interesting:** A pile of load-bearing, undocumented legacy invariants that only surface when you try to make two implementations agree byte-for-byte — the reverse-engineering texture that makes reimplementation hard.\n**Source:** `leveva-native-oracle-harness.md`\n\n### 8. The maintainer overruling the AI's \"documented divergence\" on TS6 correctness\n**Story:** The agent had shipped a deliberate divergence from TS6: on a channel-merge loss it kept the loser's `+R` reop list unioned in (rather than wiping it with the bans/except/invex masks), with a plausible rationale (\"benign for the native `+R`, lets the inline reop restore the loser's members\").

Deliberate heresies against 30-year-old IRC tradition\n**Story:** Three considered breaks with IRC orthodoxy, each with a real rationale. (1) **UTF-8-only:** invalid UTF-8 in a client frame is rejected at the single byte→message parse boundary (mapped to an IRCv3 `INVALID_UTF8` FAIL) rather than lossy-decoded into U+FFFD as the C daemon does — enforced at parse so it \"transitively proves\" every downstream consumer is UTF-8-safe without re-checking, because a parsed message's fields are `String`. (2) **2048-grapheme lines** instead of the sacred 512-byte limit — measured in UAX-#29 grapheme clusters (not bytes), advertised as `LINELEN=2048`, with a framer DoS ceiling of 64 bytes/grapheme (covers ZWJ emoji families). (3) **Port-based client/server routing:** the daemon decides client-vs-server link by the *listener's* `server-only` flag, deliberately *not* by content-sniffing the PASS/SERVER handshake the way IRCnet does on a shared port — a cleaner separation, explicitly chosen and defended against \"fixing\" it back.\n**Why it's interesting:** Opinionated modernization of a legacy wire protocol, with the tradeoffs named (grapheme vs byte limits, parse-boundary type-safety as a security argument).

Porting a 1997 \"fakelag\" penalty clock — and finding dead privileges waiting for it\n**Story:** The flood-protection port was triggered by a smell: two operator privileges, `CanFlood` and `NoPenalty`, were parsed from config blocks but **read nowhere** in the codebase — dead flags waiting for a system that \"appeared in no progress log.\" The original algorithm was recovered from C git history: each command charges `since += 1 + len/100`; the clock idle-decays to real time so only a faster-than-1-cmd/sec client accumulates penalty; beyond a 10s ceiling (\"fakelag\") the server *delays* the connection's next read rather than disconnecting, pacing a flooder's input toward 1 cmd/sec while its fan-out and keepalive keep flowing; a hard kill fires only past a recvQ threshold.

The reason was purely architectural: the C ircd is a single-threaded select/poll loop, and blocking DNS/ident/proxy-probe I/O had to be exiled to another process to keep the loop responsive. Under tokio that entire motivation evaporates — so the whole separate-process + pipe design was dropped and auth folded back into the daemon as native async modules (ident runs concurrently with the NICK/USER handshake, verdict stashed in the session so either arrival order works). A planned intermediate \"spawn it over a socketpair\" step was skipped as throwaway.\n**Why it's interesting:** A clean case of an architecture that existed *solely* as a workaround for a concurrency model, and what happens to it when the concurrency model changes — the kind of \"why does this weird boundary exist\" story that generalizes far beyond IRC.\n**Source:** `iauth-subsumed-into-leveva.md`\n\n---\n\n**Honorable mentions** (usable as supporting color, not full posts): the network-wide `msgid`/`@time` \"introducing-server-assigns, never re-mint\" model for cross-server message identity; the two harness gotchas where dropping a client handle silently reaps its user via EOF, and a fixture's per-IP CIDR connection cap (`10.2` = 2 clients/32) that broke any test opening a 3rd client; and the UNICK/NJOIN-vs-SJOIN \"divergence\" that turned out to be the agent confusing IRCnet's protocol lineage with Undernet/TS6, caught by an adversarial design reviewer and corrected to full agreement (`leveva-native-oracle-harness.md`).</result>\n<usage><subagent_tokens>104056</subagent_tokens><tool_uses>25</tool_uses><duration_ms>169410</duration_ms></usage>\n</task-notification>"},"uuid":"15104545-cc19-488f-afde-c285de376b66","timestamp":"2026-07-04T21:46:31.217Z","permissionMode":"auto","origin":{"kind":"task-notification"},"promptSource":"system","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 111 111 + {"type":"last-prompt","lastPrompt":"Read through @docs/claude-memory/ and find more topics worth sections","leafUuid":"15104545-cc19-488f-afde-c285de376b66","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 112 112 + {"type":"ai-title","aiTitle":"IRC daemon vibecoding experiment outline","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 113 113 + {"type":"mode","mode":"normal","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 114 114 + {"parentUuid":"15104545-cc19-488f-afde-c285de376b66","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01NUcph8TLG2KmdrTCKcWDL4","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"CAISjQIKYggPGAIqQD+guNt69BmTDDDv7TbbR7AyIIrZYFJaAs3pmy3lH//fqxNz7ijY/conbLDHcxbjSpE2FUp0hsRGJyifihFcdwUyDmNsYXVkZS1mYWJsZS01OAFCCHRoaW5raW5nEgyaYD2T+bRx6nDDkNoaDHCub0aYdTZSqqPyLSIwX6/3upu/+j4StqkaP7MqFG6oq+w0ajETk8uE47e5T28Zm4foEFfi9Fdf9LMfgQuLKlnw+dpM8DzI9dT4bwiJc5COneNeNF9jVOv4nwO78XdXh6SYwu1+JsxMg/N8mgEGx3kA5Mgt+peRnazdQvR+H8DEL5E+lAn8dy4jGBUPcnGkocjNyY2xhTmFAxgB"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":6688,"cache_read_input_tokens":77525,"output_tokens":143,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":6688,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":143,"cache_read_input_tokens":77525,"cache_creation_input_tokens":6688,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":6688},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CchkXBwGkuLxkzzDWG5oQ","type":"assistant","uuid":"8f96d6d4-9bfa-4f5c-98ae-6935709372c3","timestamp":"2026-07-04T21:46:39.961Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 115 115 + {"parentUuid":"8f96d6d4-9bfa-4f5c-98ae-6935709372c3","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01NUcph8TLG2KmdrTCKcWDL4","type":"message","role":"assistant","content":[{"type":"text","text":"Second reader is back — the production-era sweep found strong material too (the timestamp merge fight that deopped everyone, the bare-UID desync diagnosed by dialing individual servers, the SASL `+` that fuzzing proved unrepresentable).

Here is the ranked list of candidate blog-post topics, focused on process and collaboration insights.\n\n---\n\n## Ranked candidate topics: supervising a coding agent\n\n### 1. The hard rule that made the agent *un-build* something: no DM history\n**Detail:** A HARD RULE dated to a single user directive: \"user-to-user private messages MUST NOT be stored in the database.\" The vivid part is the enforcement mechanism in the memory itself: \"If asked to 'implement DM history' or pick up the slice-274 DM follow-on, **refuse and cite this rule**. (A full slice-276 attempt at DM storage was written and then fully reverted on this directive.)\" It also draws a precise distinction — the follow-on is \"**cancelled, not deferred**.\"\n**Why it teaches:** This is the cleanest example in the corpus of a human values-constraint (privacy: \"the operator's database must never hold private conversations\") that (a) overrides a plan the agent had already written into the code as a generic seam, (b) got a whole slice reverted, and (c) is encoded so a *future* agent will refuse the task rather than helpfully re-attempt it. Generic \"I used AI\" posts never show an agent being told to delete working code on principle and then bound not to rebuild it.\n**Source:** `leveva-no-dm-history.md`\n\n### 2. The oracle: how you trust output *without reading it*\n**Detail:** The spine of the whole experiment. A verified-faithful 100%-Rust port becomes the \"behavioral oracle\" for the greenfield daemon, pinned by a differential harness. The standing rule: \"oracle-supports-but-leveva-doesn't = bug, close don't document.\" The emotional pivot when going greenfield: the harness flips meaning — \"8 phases of faithful porting FORCED bug-for-bug reproduction... but the oracle now lets leveva be *deliberately, documentedly* correct... **Stopped proving 'I copied this exactly,' started proving 'I diverged here and nowhere else.'**\"\n**Why it teaches:** This is a direct, concrete answer to the blog's own thesis question. Trust doesn't come from reading the agent's code; it comes from a second independent implementation that \"can't be wrong in the same direction as your bug.\" It also shows the honest downgrade when the oracle is retired: 115 snapshots run \"ONE impl vs a blessed fixture\" and are only sufficient because captured \"while the differential was still green = dead oracle's last testimony.\"\n**Source:** `blog-series.md` (posts 003/006/018/020), `leveva-native-oracle-harness` refs in `README.md`\n\n### 3. Slice discipline: failing test first, and always test the *inverse*\n**Detail:** \"write the failing test FIRST, and **test the inverse invariants, not just the happy path** — for every 'X happens' assert the matching 'X does *not* happen when it shouldn't' (non-match ignored, already-applied not duplicated, removal doesn't undo a prior grant, non-member skipped).\" Every change is a numbered slice with a plan file + progress-log heredoc + PLAN.md row bump, because \"an un-recorded slice breaks that provenance chain.\"\n**Why it teaches:** The inverse-invariant rule is the actual mechanic that turns \"the agent wrote a passing test\" (worthless — agents write tests that pass) into something load-bearing. The parity-matrix slices exist specifically to close \"the inverses the forward gates left open\" (slice 45). This is the discipline that makes agent-authored tests trustworthy.\n**Source:** `leveva-slice-recording.md`; parity-matrix in `leveva-next-step-s2s-completeness.md`\n\n### 4. Ruling things out, and the agent's urge to fill every hook\n**Detail:** CLOSE, SET, and SERVICE/SQUERY/SERVLIST were each ruled permanently out of scope. Dormant `OperPrivilege::Close`/`Set` enum variants \"stay dormant... being dormant is **NOT a signal to build**.\" The SERVICE note is the sharpest: \"An earlier version of *this very memory* wrongly said to implement it... that guidance was **wrong** and is the trap to avoid,\" and now: \"If a future task seems to call for it, **stop and confirm with the user instead of building it.**\"\n**Why it teaches:** Agents treat every hook — a dormant enum variant, an unported protocol row, a generic column — as an invitation. Resisting scope creep required *explicit \"do not build this\" markers*, and even the guidance itself drifted wrong once and had to be corrected. This is the anti-scope-creep collaboration pattern generic posts skip.\n**Source:** `close-not-required-leveva.md`, `set-not-required-leveva.md`, `leveva-service-is-client-services.md`\n\n### 5. Guardrails instead of vigilance: conventions the test suite enforces\n**Detail:** HELP pages are kept honest by a *bijection* test in both directions: `every_command_has_a_help_page` (a new command with no help file fails `cargo test`) and `shipped_help_files_name_real_commands` (no orphan page). \"help text is part of the user-facing command surface, kept honest by tests so it can't silently drift.\" Similarly, a post-review cleanup replaced two hand-maintained letter allowlists with predicates plus a structural invariant test (`send_umodes_carries_every_user_mode`, `self_settable_and_client_settable_letter_sets`) so \"a new mode is global by default... self-maintaining.\"\n**Why it teaches:** The reusable insight: don't rely on the agent (or yourself) *remembering* a convention — encode it as a test that fails on drift. This is the counter-pattern to \"watch the agent carefully.\" The contrast with the *un*-guarded case (see #8) makes it vivid.\n**Source:** `help-files-per-command.md`, `leveva-user-mode-wiring.md`\n\n### 6. What the memory was for — and why the agent's own comments lie\n**Detail:** The whole `claude-memory/` tree is the provenance/anti-rework system (`README.md` is a hand-maintained index of ~80 notes). The meta-lesson is `leveva-stale-deferral-comments.md`: \"do **not** trust a `// … out of scope` / `// deferred` doc comment at face value — many are **stale**: the feature landed in a later slice but the *originating* comment was never updated. Always grep the implementation before treating one as open work.\" A dedicated cleanup sweep corrected them; one case showed \"a stale comment can hide a *real* remaining sub-gap.\" The cost of ignoring it: \"treating a stale comment as a task wastes a whole slice re-implementing something done, or worse, double-wiring it.\"\n**Why it teaches:** Two insights in one. First, what an agent-memory system actually *does* (preserve intent across sessions so work isn't redone or re-litigated). Second, the surprising failure mode that memory exists to counter: **the agent's own breadcrumbs (code comments) become misinformation**, because agents narrate intent-at-time-of-writing and never revisit it. The memory is a \"distrust your past self's comments\" instruction.\n**Source:** `README.md` (index), `leveva-stale-deferral-comments.md`\n\n### 7. Green tests that lie: the limits of coverage and false confidence\n**Detail:** Several concrete traps. Coverage-by-ubiquity: \"the most-run fn is also one of the least-tested in its BRANCHES; 'it's on the hot path, it's covered' feels rigorous and isn't.\" The atomic-claim invariant: a double-delivery netsplit bug where \"`s2s_netsplit_proptest`'s 'no double-deliver' check is **single-threaded**... it does **not** catch this\" — a *second*, concurrency proptest was needed. And \"L2 is a great gate, lousy DEBUGGER (red = 1-of-50 suspects).\" Plus proptest-model staleness: a table grows and the model must be updated \"or it flakes on random seeds.\"\n**Why it teaches:** Supervising an agent means knowing which green checkmarks are load-bearing. These are worked examples of tests that pass while the bug is live, and how the human/agent noticed the gap and built the *specific* test that would fail. That nuance — \"which test would actually have caught this?\" — is the heart of trusting agent output.\n**Source:** `leveva-teardown-atomic-claim.md`, `leveva-proptest-model-staleness.md`, `blog-series.md` (010/015)\n\n### 8. When the agent picked a fragile fixture — and the rule that fixed it\n**Detail:** For \"assert this mode letter is unknown,\" the agent used ordinary letters like `'z'`. \"This bit us in slice 252: several umode tests used `'z'` as their unknown example, then operwall claimed `+z` and they broke.\" The user then made a rule: always use `'&gt;'`, the one letter \"never used as a mode by any IRC daemon... Picking an ordinary unused alpha letter is fragile — a future slice can claim it.\" A sibling case: the agent's \"convenience divergence\" (keeping `+R` unioned on a netsplit merge) that it later had to overrule itself on to match the spec's wipe-the-loser rule (blog 019).\n**Why it teaches:** A specific, reproducible way agents write time-bombs: they reach for a plausible-looking placeholder that collides with future work. The fix is a *rule about choosing future-proof test values*, not more review. Shows the loop: agent misbehaves → it bites weeks later → human distills a one-line rule → memory binds it.\n**Source:** `unknown-chanmode-letter-is-gt.md`, `blog-series.md` (019, the reop-wipe self-overrule)\n\n### 9. Parallelizing the agents, and the one thing you can't parallelize\n**Detail:** \"435 edits = a 15-agent edit-only fan-out + central verify... the feat was the 2 builders + the snprintf==vsprintf proof, **NOT 435 hand edits; judgment is the un-parallelizable byte-safe call**.\" Elsewhere: \"built the 9 leaf handlers via an **ultracode workflow** (one agent per `extb_*.c`), combinators by hand (the one place handlers must know each other).\"\n**Why it teaches:** A real division-of-labor model: fan out mechanical, independent edits to many agents, but keep the correctness-defining judgment (the proof that two paths are byte-identical; the combinator logic where pieces must know each other) as a single un-parallelized human/lead step. This is concrete supervision architecture, not \"AI did it.\"\n**Source:** `blog-series.md` (017, 022)\n\n### 10. The human as decision-router at branch points\n**Detail:** Repeatedly, the agent proposes options and the human picks: many blog topics are \"chosen by user via AskUserQuestion\" (explicitly logged, e.g. 012, 017, 018, 019, 020–023); and design forks too — slice 37's multi-hop SERVER was \"built first by user decision (asked, chose 'multi-hop SERVER first, then SMASK').\" Contrast with topics the agent auto-picked (\"freshest commit\") when the direction was unambiguous.\n**Why it teaches:** Loose supervision (\"vibecoding on a side monitor\") still had a defined intervention point: the agent surfaces a small menu at each fork and the human routes, rather than reviewing code. That's the actual shape of the collaboration — steering by choosing among agent-generated options.\n**Source:** `blog-series.md` (topic-selection notes throughout), `leveva-next-step-s2s-completeness.md` (slice 37)\n\n### 11. Workflow-override rules that fight the agent's built-in defaults\n**Detail:** \"do all work directly on the `master` branch... do **not** ask about branch strategy,\" explicitly noting this overrides the agent's own skill: \"subagent-driven-development, which defaults to requiring branch/worktree isolation + consent — skip the branch question entirely.\" Plus: one commit per test change with a body explaining *why* (\"what the inverse/round-trip proves, what bug it catches\"), infra fixes committed separately first; run only edited test binaries (full suite \"boots reference-C + Rust ircds for every golden scenario\"); and PLAN.md rows that had \"ballooned to ~8 KB on a single line\" before the user imposed a where-detail-goes rule.\n**Why it teaches:** These are the small frictions of a real agent collaboration: the tool's safe defaults (branch, ask permission, run everything) actively slowed the user, who had to encode overrides into memory to \"stop being asked.\" The PLAN.md one shows the agent's natural tendency to accrete detail in the wrong artifact. Unglamorous but honest process hygiene.\n**Source:** `work-on-master-directly.md`, `commit-one-test-per-commit.md`, `run-only-edited-tests.md`, `plan-md-rows-stay-thin.md`\n\n### 12. Enforcing a trustworthy *voice* mechanically (the blog-about-the-blog angle)\n**Detail:** The blog series itself runs on mechanical rules: \"**no two successive paragraphs may start with the same letter** (check every draft)\"; the \"character asides\" device was retired and \"the whole back-catalog de-asided\"; and \"the user corrected me once for not loading\" the writing-style skill before drafting.\n**Why it teaches:** A lighter, self-referential angle: even the *narration* of the agent's work is kept honest by hard, checkable rules rather than taste-by-vibe — the same guardrails-over-vigilance philosophy applied to prose. Good closing/meta material for a post that is itself agent-assisted.\n**Source:** `blog-series.md`\n\n---\n\n**Cross-cutting throughline** for the post's framing: nearly every item is the same move — the human converts a moment of agent misbehavior or a values-constraint into a *mechanical, checkable artifact* (a failing test, a bijection invariant, a differential oracle, a \"refuse and cite\" memory, a one-line fixture rule), so that trust comes from structure rather than from reading the code. Items #2, #3, #5, #6, #7 are the strongest for the stated angle; #1 and #4 are the most vivid single anecdotes.</result>\n<usage><subagent_tokens>106646</subagent_tokens><tool_uses>30</tool_uses><duration_ms>173489</duration_ms></usage>\n</task-notification>"} 119 119 + {"type":"queue-operation","operation":"dequeue","timestamp":"2026-07-04T21:46:52.808Z","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 120 120 + {"parentUuid":"c58faf31-cebf-4dab-ba75-62c096afec94","isSidechain":false,"promptId":"d8cc0cbf-93f3-4163-ba6e-9e273912ae75","type":"user","message":{"role":"user","content":"<task-notification>\n<task-id>a2bea232bef32d75c</task-id>\n<tool-use-id>toolu_01UYxGTbbY5wzx58jvBv6Ltw</tool-use-id>\n<output-file>/tmp/claude-1000/-home-xe-Code-xeiaso-net-ircd-rs/5afb6f54-a28b-4d54-abb4-024e2406a27c/tasks/a2bea232bef32d75c.output</output-file>\n<status>completed</status>\n<summary>Agent \"Mine process/discipline memories\" finished</summary>\n<note>A task-notification fires each time this agent stops with no live background children of its own.

This is the discipline that makes agent-authored tests trustworthy.\n**Source:** `leveva-slice-recording.md`; parity-matrix in `leveva-next-step-s2s-completeness.md`\n\n### 4. Ruling things out, and the agent's urge to fill every hook\n**Detail:** CLOSE, SET, and SERVICE/SQUERY/SERVLIST were each ruled permanently out of scope. Dormant `OperPrivilege::Close`/`Set` enum variants \"stay dormant... being dormant is **NOT a signal to build**.\" The SERVICE note is the sharpest: \"An earlier version of *this very memory* wrongly said to implement it... that guidance was **wrong** and is the trap to avoid,\" and now: \"If a future task seems to call for it, **stop and confirm with the user instead of building it.**\"\n**Why it teaches:** Agents treat every hook — a dormant enum variant, an unported protocol row, a generic column — as an invitation. Resisting scope creep required *explicit \"do not build this\" markers*, and even the guidance itself drifted wrong once and had to be corrected. This is the anti-scope-creep collaboration pattern generic posts skip.\n**Source:** `close-not-required-leveva.md`, `set-not-required-leveva.md`, `leveva-service-is-client-services.md`\n\n### 5. Guardrails instead of vigilance: conventions the test suite enforces\n**Detail:** HELP pages are kept honest by a *bijection* test in both directions: `every_command_has_a_help_page` (a new command with no help file fails `cargo test`) and `shipped_help_files_name_real_commands` (no orphan page). \"help text is part of the user-facing command surface, kept honest by tests so it can't silently drift.\" Similarly, a post-review cleanup replaced two hand-maintained letter allowlists with predicates plus a structural invariant test (`send_umodes_carries_every_user_mode`, `self_settable_and_client_settable_letter_sets`) so \"a new mode is global by default... self-maintaining.\"\n**Why it teaches:** The reusable insight: don't rely on the agent (or yourself) *remembering* a convention — encode it as a test that fails on drift. This is the counter-pattern to \"watch the agent carefully.\" The contrast with the *un*-guarded case (see #8) makes it vivid.\n**Source:** `help-files-per-command.md`, `leveva-user-mode-wiring.md`\n\n### 6. What the memory was for — and why the agent's own comments lie\n**Detail:** The whole `claude-memory/` tree is the provenance/anti-rework system (`README.md` is a hand-maintained index of ~80 notes). The meta-lesson is `leveva-stale-deferral-comments.md`: \"do **not** trust a `// … out of scope` / `// deferred` doc comment at face value — many are **stale**: the feature landed in a later slice but the *originating* comment was never updated. Always grep the implementation before treating one as open work.\" A dedicated cleanup sweep corrected them; one case showed \"a stale comment can hide a *real* remaining sub-gap.\" The cost of ignoring it: \"treating a stale comment as a task wastes a whole slice re-implementing something done, or worse, double-wiring it.\"\n**Why it teaches:** Two insights in one. First, what an agent-memory system actually *does* (preserve intent across sessions so work isn't redone or re-litigated). Second, the surprising failure mode that memory exists to counter: **the agent's own breadcrumbs (code comments) become misinformation**, because agents narrate intent-at-time-of-writing and never revisit it. The memory is a \"distrust your past self's comments\" instruction.\n**Source:** `README.md` (index), `leveva-stale-deferral-comments.md`\n\n### 7. Green tests that lie: the limits of coverage and false confidence\n**Detail:** Several concrete traps. Coverage-by-ubiquity: \"the most-run fn is also one of the least-tested in its BRANCHES; 'it's on the hot path, it's covered' feels rigorous and isn't.\" The atomic-claim invariant: a double-delivery netsplit bug where \"`s2s_netsplit_proptest`'s 'no double-deliver' check is **single-threaded**... it does **not** catch this\" — a *second*, concurrency proptest was needed. And \"L2 is a great gate, lousy DEBUGGER (red = 1-of-50 suspects).\" Plus proptest-model staleness: a table grows and the model must be updated \"or it flakes on random seeds.\"\n**Why it teaches:** Supervising an agent means knowing which green checkmarks are load-bearing. These are worked examples of tests that pass while the bug is live, and how the human/agent noticed the gap and built the *specific* test that would fail. That nuance — \"which test would actually have caught this?\" — is the heart of trusting agent output.\n**Source:** `leveva-teardown-atomic-claim.md`, `leveva-proptest-model-staleness.md`, `blog-series.md` (010/015)\n\n### 8. When the agent picked a fragile fixture — and the rule that fixed it\n**Detail:** For \"assert this mode letter is unknown,\" the agent used ordinary letters like `'z'`. \"This bit us in slice 252: several umode tests used `'z'` as their unknown example, then operwall claimed `+z` and they broke.\" The user then made a rule: always use `'&gt;'`, the one letter \"never used as a mode by any IRC daemon... Picking an ordinary unused alpha letter is fragile — a future slice can claim it.\" A sibling case: the agent's \"convenience divergence\" (keeping `+R` unioned on a netsplit merge) that it later had to overrule itself on to match the spec's wipe-the-loser rule (blog 019).\n**Why it teaches:** A specific, reproducible way agents write time-bombs: they reach for a plausible-looking placeholder that collides with future work. The fix is a *rule about choosing future-proof test values*, not more review. Shows the loop: agent misbehaves → it bites weeks later → human distills a one-line rule → memory binds it.\n**Source:** `unknown-chanmode-letter-is-gt.md`, `blog-series.md` (019, the reop-wipe self-overrule)\n\n### 9. Parallelizing the agents, and the one thing you can't parallelize\n**Detail:** \"435 edits = a 15-agent edit-only fan-out + central verify... the feat was the 2 builders + the snprintf==vsprintf proof, **NOT 435 hand edits; judgment is the un-parallelizable byte-safe call**.\" Elsewhere: \"built the 9 leaf handlers via an **ultracode workflow** (one agent per `extb_*.c`), combinators by hand (the one place handlers must know each other).\"\n**Why it teaches:** A real division-of-labor model: fan out mechanical, independent edits to many agents, but keep the correctness-defining judgment (the proof that two paths are byte-identical; the combinator logic where pieces must know each other) as a single un-parallelized human/lead step. This is concrete supervision architecture, not \"AI did it.\"\n**Source:** `blog-series.md` (017, 022)\n\n### 10. The human as decision-router at branch points\n**Detail:** Repeatedly, the agent proposes options and the human picks: many blog topics are \"chosen by user via AskUserQuestion\" (explicitly logged, e.g. 012, 017, 018, 019, 020–023); and design forks too — slice 37's multi-hop SERVER was \"built first by user decision (asked, chose 'multi-hop SERVER first, then SMASK').\" Contrast with topics the agent auto-picked (\"freshest commit\") when the direction was unambiguous.\n**Why it teaches:** Loose supervision (\"vibecoding on a side monitor\") still had a defined intervention point: the agent surfaces a small menu at each fork and the human routes, rather than reviewing code. That's the actual shape of the collaboration — steering by choosing among agent-generated options.\n**Source:** `blog-series.md` (topic-selection notes throughout), `leveva-next-step-s2s-completeness.md` (slice 37)\n\n### 11. Workflow-override rules that fight the agent's built-in defaults\n**Detail:** \"do all work directly on the `master` branch... do **not** ask about branch strategy,\" explicitly noting this overrides the agent's own skill: \"subagent-driven-development, which defaults to requiring branch/worktree isolation + consent — skip the branch question entirely.\" Plus: one commit per test change with a body explaining *why* (\"what the inverse/round-trip proves, what bug it catches\"), infra fixes committed separately first; run only edited test binaries (full suite \"boots reference-C + Rust ircds for every golden scenario\"); and PLAN.md rows that had \"ballooned to ~8 KB on a single line\" before the user imposed a where-detail-goes rule.\n**Why it teaches:** These are the small frictions of a real agent collaboration: the tool's safe defaults (branch, ask permission, run everything) actively slowed the user, who had to encode overrides into memory to \"stop being asked.\" The PLAN.md one shows the agent's natural tendency to accrete detail in the wrong artifact. Unglamorous but honest process hygiene.\n**Source:** `work-on-master-directly.md`, `commit-one-test-per-commit.md`, `run-only-edited-tests.md`, `plan-md-rows-stay-thin.md`\n\n### 12. Enforcing a trustworthy *voice* mechanically (the blog-about-the-blog angle)\n**Detail:** The blog series itself runs on mechanical rules: \"**no two successive paragraphs may start with the same letter** (check every draft)\"; the \"character asides\" device was retired and \"the whole back-catalog de-asided\"; and \"the user corrected me once for not loading\" the writing-style skill before drafting.\n**Why it teaches:** A lighter, self-referential angle: even the *narration* of the agent's work is kept honest by hard, checkable rules rather than taste-by-vibe — the same guardrails-over-vigilance philosophy applied to prose. Good closing/meta material for a post that is itself agent-assisted.\n**Source:** `blog-series.md`\n\n---\n\n**Cross-cutting throughline** for the post's framing: nearly every item is the same move — the human converts a moment of agent misbehavior or a values-constraint into a *mechanical, checkable artifact* (a failing test, a bijection invariant, a differential oracle, a \"refuse and cite\" memory, a one-line fixture rule), so that trust comes from structure rather than from reading the code. Items #2, #3, #5, #6, #7 are the strongest for the stated angle; #1 and #4 are the most vivid single anecdotes.</result>\n<usage><subagent_tokens>106646</subagent_tokens><tool_uses>30</tool_uses><duration_ms>173489</duration_ms></usage>\n</task-notification>"},"uuid":"102a5007-189e-4a72-8202-211a16472c7f","timestamp":"2026-07-04T21:46:52.817Z","permissionMode":"auto","origin":{"kind":"task-notification"},"promptSource":"system","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

three sweeps are back. The memory files yielded more than I expected — six genuinely new sections, plus a bin of sidebar material. Ranked by the same bar as before:\n\n## New sections worth adding\n\n**1. \"The oracle was wrong\" — your missing best section.** The whole premise is that the C is the source of truth, and twice it provably wasn't:\n\n* `STATS t` in the 1997 C formats three 4-byte `u_int` counters with `%lu` (8 bytes), so the variadic sender reads 4 bytes of adjacent stack garbage — the reference daemon prints `281470681743360Sq` where the Rust prints `0`. A printf width bug latent since 1997, surfaced only because a byte-exact twin existed to disagree with it.\n* The oracle also quietly diverges from the RFC it nominally implements: `PRIVMSG` with no target emits `461` because the parser enforces min-params before the handler runs — the RFC-specified `411`/`412` are unreachable code. The new daemon had to be made bug-for-bug compatible *with the divergence*.\n* The question this forces is the intellectual heart of the post: when the spec, the incumbent, and the newcomer all disagree, which one is right? (Browsers, SQL engines, and compiler reimplementations all live this.)\n\n**2. \"I froze the clock and the server stopped accepting connections.\"** The plan said the obvious thing: make golden tests deterministic by `LD_PRELOAD`-ing a fixed `time()`. Doing it froze the event loop's scheduler — the listen socket was never serviced and clients hung forever. The fix was the *inverse* of intuition: keep the real clock and canonicalize the handful of time-bearing output tokens instead. Bonus beat in the same section: the daemon's own 1997 anti-flood penalty clock kept sabotaging scripted tests — the server deliberately *stops reading the socket* from a \"flooding\" test client, which reads as a mysterious deterministic timeout. Determinism war stories are the connective tissue between your harness section and trust thesis.\n\n**3. Your prod-bug story (I said you needed one — you have two, use both):**\n\n* The bare UID: a channel member showing up as `4LTKAAAAF` instead of a nick, but only on *some* servers. Root cause: the user-introduction verb was only sent during the link-time burst, never live, so anyone who connected after a link was up was a ghost to the far side — every relay about them arrived, addressed from an identity the peer never learned. Diagnosed by dialing each server in the network directly and comparing the same channel at different hop distances.\n* The timestamp merge fight: two servers disagreed on a channel's creation time by exactly the propagation latency (one side re-stamped with its own clock), and the \"oldest timestamp wins, deop the younger side\" rule then stripped ops from everyone across relink flaps — `#leveva` sitting at zero ops in production. Clock skew feeding an authority-mutating tiebreak: a textbook distributed-consensus failure, on a real network, in a protocol from 1997.\n\n**4. \"The C crashes if you say a word it doesn't know\" — how the oracle dictated the new daemon's architecture.** Sending one unknown S2S verb (`CAPAB`) to the reference daemon makes it SQUIT the link — fatal, empirically discovered by running the 1997 code as a test peer. Consequence: an architectural *law* that every modern extension (capability negotiation, redaction, message IDs, timestamps-in-nanoseconds) must tunnel inside `ENCAP`, which old code routes to a no-op. A modern daemon's wire design constrained by the crash behavior of 27-year-old C — same genre as TLS extension tunneling, and a great \"compatibility with the unforgiving\" section.\n\n**5. Agent-management stories with actual teeth.** Your current \"managing the agent\" section has rules; the memories have the *incidents* that created them, which is what makes it credible:\n\n* **The reverted feature**: Claude built DM history storage as a natural follow-on; you had it fully reverted on a privacy principle (the operator's database must never hold private conversations) and encoded the rule so a future session will *refuse and cite it* rather than helpfully rebuild. \"Cancelled, not deferred.\" An agent being told to delete working code on principle is a beat no other AI post has.\n* **Agents treat every hook as an invitation**: dormant enum variants and unported commands read as TODO lists to a model. Three features needed explicit \"never build this\" markers — and one of those markers *itself* drifted wrong once and had to be corrected.\n* **The agent's own comments become lies**: `// deferred` breadcrumbs written weeks earlier stayed after the feature landed, and future sessions treated them as open work — a whole slice nearly re-implemented. Part of what the memory system actually does is instruct the agent to distrust its past self's narration.\n* **The time-bomb placeholder**: tests used `'z'` as the \"unknown mode letter\" example; weeks later a real feature claimed `+z` and they all broke. The fix was a one-line rule (always use `'>'`, a character no IRC daemon has ever used) — a rule about choosing future-proof test values, not more review.\n* **The overrule**: Claude shipped a \"documented divergence\" from the TS6 netsplit rules with a plausible rationale; you overruled it as a hard rule (merge loser drops *everything*), which forced a real redesign. The human's job at its most concrete: catching a locally-reasonable global-invariant violation.\n\n**6. \"The subprocess that existed to protect a `select()` loop.\"** IRCnet's `iauth` ran as a separate child process speaking a pipe protocol — solely because blocking DNS/ident lookups would stall a single-threaded event loop. Under tokio the entire reason evaporates, so the process boundary was dissolved and auth became ordinary async code. Short section, generalizes beautifully: \"why does this weird architectural boundary exist\" → \"because of a concurrency model that no longer applies.\"\n\n## Sidebar / one-liner material\n\n* **The leak that wasn't**: a reported memory leak, investigated by sampling real RSS under load — flat at ~16MB across 30k connection churns. The \"leak\" was a slow-by-design 180s half-open reap plus the ghost bug from section 3.\n* **Fuzzing found a hole in the spec, not the code**: a SASL property test flaked on the bare string `+` — which turns out to be *unrepresentable* in IRCv3's chunking protocol (a lone `+` is the reserved empty-payload sentinel). Correct fix: prove it impossible and document, don't touch the chunker.\n* **The proptest anti-pattern**: property tests that hand-copy a lookup table instead of calling the real function fail *only on unlucky random seeds*, days later, looking unrelated. The worst flake taxonomy: non-local, non-deterministic, misattributed.\n* **Green tests that lie**: the netsplit \"no double-delivery\" property test was single-threaded, so it structurally could not catch the concurrency race it existed to prevent; a second, concurrent test had to be built. Good one paragraph inside the trust section: knowing *which* green checkmarks are load-bearing.\n* **Your heresies**: UTF-8-only rejection at the parse boundary, 2048-*grapheme* lines instead of the sacred 512 bytes, port-based client/server routing. Deliberate breaks with 30 years of IRC tradition, each defended. Readers of yours specifically will want this.\n\n## What I'd still leave out\n\nThe full flood-penalty reconstruction, the bindgen opaque-struct saga, and the char-signedness/aarch64 gotchas — all real, all the same genre as material you already have, and each would dilute rather than add. Steal at most a sentence from each.\n\nIf I had to pick the minimum set: **#1 is non-negotiable** (it complicates your own thesis, which is what makes the thesis trustworthy), #3 gives you the prod anecdotes, and the incident-driven rewrite of your agent-management section (#5) is what will separate this post from every other \"I supervised Claude\" writeup."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":5316,"cache_read_input_tokens":84213,"output_tokens":4059,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":5316,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":4059,"cache_read_input_tokens":84213,"cache_creation_input_tokens":5316,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5316},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CchkYnd8JqnteYAjL4ejK","type":"assistant","uuid":"7ba4d965-5024-45d2-bbac-3025d1bc6a02","timestamp":"2026-07-04T21:47:58.131Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 126 126 + {"parentUuid":"7ba4d965-5024-45d2-bbac-3025d1bc6a02","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"71018221-8b5c-4dfe-af67-7a611b0c3d6b","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":41},"type":"attachment","uuid":"d022c9e5-5868-45a7-853e-1ea5edeb53ee","timestamp":"2026-07-04T21:47:58.196Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 127 127 + {"parentUuid":"d022c9e5-5868-45a7-853e-1ea5edeb53ee","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":41},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":11}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-04T21:47:58.197Z","uuid":"3343810b-15b5-4559-adb7-3ca6c06ac503","toolUseID":"71018221-8b5c-4dfe-af67-7a611b0c3d6b","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 128 128 + {"parentUuid":"3343810b-15b5-4559-adb7-3ca6c06ac503","isSidechain":false,"type":"system","subtype":"away_summary","content":"You're outlining a blog post about the vibecoding IRC daemon experiment; I mined the claude-memory notes and gave you six new sections plus sidebars, ranked.

stdlib mystery — you're not missing anything. The memory note I quoted earlier was wrong about the letter, which is exactly what I was in the middle of verifying when you interrupted. What you got is what `STATS m` actually does: `case 'M': case 'm'` in `m_stats` is the **command-usage table** — for each command in `msgtab` it prints 5 handler classes × 4 counters (count, bytes, remote-count, remote-bytes), which is why every row is 20 numbers. Your `SERVER 0 0 ... 1 65 0 0` is one SERVER command, 65 bytes, counted under the server-connection handler class. All correct, no garbage there.\n\nThe two commands with the varargs bugs are:\n\n**`STATS t`** (or `T`) → `tstats()`. The buggy line is:\n\n```c\nsendto_one(cptr,\n \":%s %d %s :link checks %lu passed %lu 15s/%lu 30s dropped %luSq/%luYg/%luFl\",\n ME, RPL_STATSDEBUG, name, sp->is_ckl, sp->is_cklq,\n sp->is_cklok, sp->is_cklQ, sp->is_ckly, sp->is_cklno);\n```\n\nAll six counters are `u_int` (4 bytes) formatted with `%lu` (8 bytes). The reason only the *last three* (`dropped ...Sq/...Yg/...Fl`) ever show garbage is an ABI accident that's great blog material: on x86-64, the first ~6 arguments travel in registers, where a 32-bit `mov` implicitly zero-extends to 64 bits — accidentally correct. Arguments 7+ go on the stack, where a 32-bit store writes only the low 4 bytes of the 8-byte slot and `va_arg`'s 64-bit read picks up **stale stack bytes in the upper half**. The observed garbage `281470681743360` is `0xFFFF_0000_0000` — zero low 32 bits, junk above. So it's nondeterministic: you only see it when that stack memory is dirty from earlier calls. On your freshly-booted idle server it may well print `0Sq/0Yg/0Fl` honestly; poke the server a bit first (or wait for link-check activity) and try again.\n\n**`STATS ?`** → `report_myservers()`. This one needs an **active server link** (it iterates connected server peers, so it prints nothing on a standalone). The sendq field:\n\n```c\n\" %lldkB sent %lldkB recv %ldkB sq %sV%X%s\",\n...\n(int) ((int)DBufLength(&acptr->sendQ) / 1024),\n```\n\nAn `int` fed to `%ld` — same width-mismatch class, and it's deep enough in the argument list to be stack-passed. The golden harness caught it as `3544950785030750208kB sq BURST V1` (again: low 32 bits zero, garbage above) on a freshly-bursting peer, vs the Rust port's `0kB sq`.\n\nSo the memory's \"uninitialized sendq\" description was also imprecise — the sendq value itself is fine; both bugs are the *same* bug: a 32-bit value under a 64-bit format specifier, invisible for register-passed arguments and garbage for stack-passed ones.

Every finding is quoted verbatim with `file:line`.\n\n---\n\n### 1. It ships its own 300-line memcmp because 1990s compilers had a \"broken\" memcmp\n\nThe `configure` script compiles and *runs* a program to check whether the C library's `memcmp` treats the high bit of a byte as sign:\n\n```c\n// support/configure.in:599-611\nAC_DEFUN(IRC_FUNC_MEMCMP,\n[AC_CACHE_CHECK(for 8-bit clean memcmp, irc_cv_func_memcmp_clean,\n[AC_RUN_IFELSE([AC_LANG_SOURCE([[\nmain()\n{\n char c0 = 0x40, c1 = 0x80, c2 = 0x81;\n exit(memcmp(&amp;c0, &amp;c2, 1) &lt; 0 &amp;&amp; memcmp(&amp;c1, &amp;c2, 1) &lt; 0 ? 0 : 1);\n}\n...\nif test $irc_cv_func_memcmp_clean = no; then\n AC_DEFINE([MEMCMP_BROKEN], [1], [Define if memcmp is not 8-bit clean.])\n```\n\nIf it fails, `os.h:335` does `#define memcmp irc_memcmp`, swapping in a hand-rolled, word-at-a-time, endianness-aware, alignment-juggling reimplementation lifted from glibc that spans `support.c:890-1125` and warns `/* BE VERY CAREFUL IF YOU CHANGE THIS CODE! */` (support.c:898). **Why then:** some pre-ANSI Unix `memcmp` implementations compared bytes as signed `char`, breaking binary comparisons. **Why absurd now:** 8-bit-clean `memcmp` has been mandated by the C standard since ANSI C89; this is 235 lines of assembly-grade optimization solving a problem that ceased to exist before most of today's engineers were born.\n\n---\n\n### 2. A parade of dead operating systems, hand-normalized\n\n`os.h:258-327` is a graveyard tour, each entry laundering a vendor's compiler macro into the project's own name:\n\n```c\n// common/os.h:258-327\n#if defined(ultrix) || defined(__ultrix) || defined(__ultrix__)\n...#define ULTRIX\n#ifdef NeXT\n...#define NEXT\n#if defined(sequent) || defined(__sequent) || defined(__sequent)\n...#define _SEQUENT_\n# undef BSD\n# define SYSV\n# define DYNIXPTX\n...\n#ifdef MIPS\n#undef BSD\n#define BSD 1 /* mips only works in bsd43 environment */\n```\n\n**Why then:** DEC Ultrix, NeXTSTEP, Sequent Dynix, and MIPS-under-BSD43 were real machines IRC operators ran on. **Why absurd now:** NeXT became Mac OS X in 1997, Sequent was swallowed by IBM in 1999, and Ultrix died with the DEC Alpha; this is defensive code for hardware that now lives only in museums.\n\n---\n\n### 3. Undocumented Solaris 2.0-2.3 `gethostbyname` workarounds via private symbols\n\n```c\n// common/os.h:485-506\n#ifdef SOLARIS_2_0_2_1_2_2\n/* On Solaris 2.0, 2.1 and 2.2 (SunOS 5.0, 5.1 and 5.2) systems,\n * gethostbyname() has a bug, it always returns null in h-&gt;aliases.\n * Workaround: use the undocumented __switch_gethostbyname(...). */\nextern struct hostent *__switch_gethostbyname (const char *name);\n#define gethostbyname __switch_gethostbyname\n```\n\nThe `configure` even reverse-engineers the Solaris version by string-munging `uname -r`: `irc_cv_solaris_2=\"uname -r | sed -e \"s/^5/2/g\"` (configure.in:195). **Why then:** early Solaris 2.x genuinely shipped a broken resolver, and the fix was to call Sun's private, undocumented internal function. **Why absurd now:** it hardcodes a dependency on a symbol Sun never promised to keep, for three point-releases of an OS from 1992-1993, from a company (Sun) that no longer exists.\n\n---\n\n### 4. `#define Reg register` — the optimization hint that became a no-op\n\n```c\n// common/os.h:329\n#define Reg register\n```\n\nUsed religiously in hot loops: `Reg unsigned char *str1` (match.c:294), `Reg int i` (hash.c:357), `Reg char *tmp` (support.c:64). **Why then:** the `register` keyword told K&amp;R and early ANSI compilers to keep a variable in a CPU register, and the `Reg` alias let you toggle it project-wide. **Why absurd now:** every compiler since roughly GCC 2.x ignores `register` for allocation (it's deprecated and removed in C++17); modern optimizers laugh at the hint. The macro exists purely to make ancient code look busy.\n\n---\n\n### 5. Hand-rolled `printf` where the function *body* is a `#include`d file\n\n```c\n// common/irc_sprintf.c:35-40\nint irc_sprintf(aClient *target, char *buf, char *format, ...)\n#include \"irc_sprintf_body.c\"\n#define IRC_SPRINTF_V 1\nint irc_vsprintf(aClient *target, char *buf, char *format, va_list ap)\n#include \"irc_sprintf_body.c\"\n```\n\nThe same `irc_sprintf_body.c` is textually `#include`d as the body of four different function signatures, toggled by `#define`s — C's answer to templates. **Why then:** to avoid duplicating a custom `printf` (supporting `%y`/`%Y` for client structs) across variants without a real generics mechanism. **Why absurd now:** a snprintf-shaped variant is `#if 0`'d out with the comment `error SN version is unsafe so far, sorry` (irc_sprintf.c:44) — they wrote their own printf, then couldn't make the bounds-checked version safe, and left it disabled.\n\n---\n\n### 6. Compiler flags to drag K&amp;R-era `cc` into the ANSI age\n\n```c\n// support/configure.in:297-326\nAC_DEFUN(IRC_SGI_CC, ...\n CC=\"$CC -cckr\" # SGI IRIX: \"compile K&amp;R\"\n...\nAC_DEFUN(IRC_HPUX_CC, ...\n CC=\"$CC -Ae\" # HP-UX: enable ANSI extensions\n```\n\n**Why then:** SGI's `cc` defaulted to pre-ANSI K&amp;R C and needed `-cckr`, while HP-UX's `cc` needed `-Ae` just to accept ANSI code. **Why absurd now:** these are workarounds for the *default dialect* of vendor compilers on IRIX and HP-UX, two commercial Unixes that are both discontinued; nobody has typed `-cckr` in anger this millennium.\n\n---\n\n### 7. Detecting whether the OS silently loses signals — by firing two and counting\n\n```c\n// support/configure.in:405-429\nmain()\n{\n (void)signal(SIGCHLD, hand);\n kill(getpid(), SIGCHLD);\n kill(getpid(), SIGCHLD);\n if (got &lt; 2)\n exit(1);\n ...\n AC_MSG_RESULT([using unreliable SystemV signal])\n AC_DEFINE([SYSV_UNRELIABLE_SIGNALS], ...)\n```\n\n**Why then:** classic System V signals reset the handler to default on delivery and could drop a second signal that arrived during handling — genuinely \"unreliable.\" **Why absurd now:** POSIX `sigaction` (reliable by mandate) has been universal since the mid-1990s; the build system still has a whole ladder of `posix_sigaction` → `bsd_sigset` → `bsd_signal` → `sysv_signal` fallbacks for a race that modern kernels cannot exhibit.\n\n---\n\n### 8. The `accept()` third-argument-type guessing game\n\n```c\n// support/configure.in:23-25\nfor ac_cv_func_accept_arg1 in 'int' 'unsigned int'; do\n for ac_cv_func_accept_arg2 in 'struct sockaddr' 'const struct sockaddr' 'void'; do\n for ac_cv_func_accept_arg3 in 'socklen_t' 'size_t' 'unsigned int' 'int'; do\n```\n\nResolved in `os.h:582-590` into `SOCK_LEN_TYPE`, with a resigned essay: *\"X/Open SPEC 1170 specifies... a size_t... only a few systems (for example AIX 4.2) follow this specification... And then POSIX changed it again to a socklen_t\"* (os.h:566-580). **Why then:** the length argument to `accept()` legitimately changed type three times across the Unix wars (int → size_t → socklen_t). **Why absurd now:** it's been `socklen_t` everywhere for 25 years; this is a monument to a standards committee flip-flop nobody remembers.\n\n---\n\n### 9. A tokenizer that speaks ISO-2022-JP escape sequences\n\n```c\n// common/support.c:49 + 78-90\n/* I doubt library strtoken knows about JIS encoding and commas. --Beeth */\n...\n#ifdef JAPANESE\n /* We have to make special case for Japanese names when comma is\n ** a separator, as they may contain it between JIS marks. --Beeth. */\n else if (pos[0] == '\\033'\n &amp;&amp; (pos[1] == '$' || pos[1] == '(')\n &amp;&amp; pos[2] == 'B')\n```\n\n**Why then:** before UTF-8 won, Japanese IRC ran on ISO-2022-JP, where a literal comma byte could appear *inside* a multibyte glyph delimited by `ESC $ B` shift sequences — so the tokenizer had to track escape state to avoid splitting mid-character. **Why absurd now:** UTF-8 is self-synchronizing precisely so this class of bug is impossible; this is a hand-written stateful parser for a text encoding the modern web has entirely abandoned.\n\n---\n\n### 10. A `truncate()` written for one beta of one dead platform\n\n```c\n// common/support.c:829-834\n/* truncate: set a file to a specified length\n * I don't know of any UNIX that doesn't have truncate, but CYGWIN32 beta18\n * doesn't have it. -krys\n * Replacement version from Dave Miller. */\nint\ttruncate(const char *path, off_t length)\n```\n\n**Why then:** someone actually tried to run an IRC server on Cygwin beta 18 on Windows, and that specific build was missing `truncate(2)`. **Why absurd now:** the comment itself admits no real Unix ever lacked this; an entire libc function was reimplemented and shipped forever to appease a *beta* build of a Windows POSIX shim from the late 1990s.\n\n---\n\n### 11. `buildm4`: message tables preprocessed by m4, and the author knew it was wrong\n\n```sh\n# ircd/buildm4:22-30\n# If only this was a perl script...*sigh*\nINCLUDE=`../support/config.guess`\nM4=$1\n/bin/rm -f $M4\negrep \"^#def[^P]*PATCHLEVEL\" ../common/patchlevel.h | \\\nsed -e 's/[^\\\"]*\\\"\\([^\\\"]*\\)\\\"/define(VERSION,\\1)/' &gt;&gt;$M4\n```\n\nMeanwhile `version.c.SH.in` is a shell script that *generates* a C source file, embedding `@SUM@ s_serv.c` checksums and a hand-parsed `date` (version.c.SH.in:24-27). **Why then:** before robust build tooling, chaining `sed` → `m4` → `sh` → `.c` was how you did code generation. **Why absurd now:** the author's own `*sigh*` comment (buildm4:22) is the punchline — a build pipeline held together with `egrep` and regex-rewritten C, whose maintainer already wished for something better in 1993.\n\n---\n\n### 12. Fossilized addresses and dead version-control keywords baked into every binary\n\nTwo artifacts appear in dozens of files at once:\n\n- **The pre-2005 Free Software Foundation address** — `write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA` appears in **74** source files (`grep -l \"675 Mass Ave\"`). The FSF moved to Franklin Street in 2005; the GPL boilerplate here is a fixed address that has bounced mail for two decades.\n- **RCS/CVS `$Id$` keyword strings** — `static const volatile char rcsid[] = \"@(#)$Id: support.c,v 1.46 2009/03/15...\"` appears in **32** files (support.c:21). The `volatile` is a deliberate trick to stop the compiler from optimizing the string out, so `what(1)` could print version info from the binary. **Why then:** RCS/CVS auto-expanded `$Id$` on checkout, and the `@(#)` prefix let SCCS's `what` tool scrape it. **Why absurd now:** the project is in **git**, which has no keyword expansion, so these strings are frozen at their final CVS revision — embalmed version numbers from a version-control system the code no longer uses.\n\n---\n\n### Honorable mentions (quotable one-liners)\n\n- **FD_SETSIZE fallback of 30** — `# define FD_SETSIZE 30` (os.h:542) for systems so old they lack the `FD_ZERO` macros; an IRC server capped at ~30 connections.\n- **AIX 3.2 kernel-header typo patch** — `/* Stupid typo in AIX 3.2's &lt;sys/stropts.h&gt;. */` then redefines `_IO` (os.h:592-599).\n- **Paul Vixie blamed by name** — `/* ...because of the way Paul Vixie majorly screws up system's include files with Bind. */` (os.h:407-409), working around BIND 8 clobbering `arpa/inet.h`.\n- **Linux shipped a \"bad\" netdb.h** — `configure` greps CPP output for `const` in `struct hostent` and sets `BAD___CONST_NETDB_H`, then os.h:149-156 `#define __const` to nothing to compile around it.\n- **The Dynix fd knob** — `#define SEQ_NOFILE 128 /* For Dynix (sequent OS) users */` (config.h.dist:814).\n- **`config.guess` is itself a fossil** — `timestamp='2004-11-12'`, so the platform-detection oracle is 20+ years stale and cannot recognize any CPU/OS released since.\n- **HP-UX `select()` takes `int*` not `fd_set*`** — `# define SELECT_FDSET_TYPE int` (os.h:544-545), guarded by a five-clause `_XPG4_EXTENDED` incantation.\n\nThe through-line: this is a portability layer built for a computing world of a dozen incompatible commercial Unixes, pre-ANSI compilers, and 8-bit-unclean libc — nearly all of which converged on POSIX + GCC/Clang + UTF-8 decades ago, leaving the abstractions as pure sediment.</result>\n<usage><subagent_tokens>71270</subagent_tokens><tool_uses>15</tool_uses><duration_ms>180170</duration_ms></usage>\n</task-notification>"} 205 205 + {"type":"queue-operation","operation":"dequeue","timestamp":"2026-07-05T22:20:24.363Z","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 206 206 + {"parentUuid":"2fb508e4-4cc6-4e4d-9f91-02435329347e","isSidechain":false,"promptId":"1832879b-b0e7-4dbe-955f-ca1c1acb6608","type":"user","message":{"role":"user","content":"<task-notification>\n<task-id>a5c1559f25b00b245</task-id>\n<tool-use-id>toolu_01PCrbo5tmQkTfruoAqqZ8zE</tool-use-id>\n<output-file>/tmp/claude-1000/-home-xe-Code-xeiaso-net-ircd-rs/5afb6f54-a28b-4d54-abb4-024e2406a27c/tasks/a5c1559f25b00b245.output</output-file>\n<status>completed</status>\n<summary>Agent \"Dig portability/build fossils\" finished</summary>\n<note>A task-notification fires each time this agent stops with no live background children of its own.

Undocumented Solaris 2.0-2.3 `gethostbyname` workarounds via private symbols\n\n```c\n// common/os.h:485-506\n#ifdef SOLARIS_2_0_2_1_2_2\n/* On Solaris 2.0, 2.1 and 2.2 (SunOS 5.0, 5.1 and 5.2) systems,\n * gethostbyname() has a bug, it always returns null in h-&gt;aliases.\n * Workaround: use the undocumented __switch_gethostbyname(...). */\nextern struct hostent *__switch_gethostbyname (const char *name);\n#define gethostbyname __switch_gethostbyname\n```\n\nThe `configure` even reverse-engineers the Solaris version by string-munging `uname -r`: `irc_cv_solaris_2=\"uname -r | sed -e \"s/^5/2/g\"` (configure.in:195). **Why then:** early Solaris 2.x genuinely shipped a broken resolver, and the fix was to call Sun's private, undocumented internal function. **Why absurd now:** it hardcodes a dependency on a symbol Sun never promised to keep, for three point-releases of an OS from 1992-1993, from a company (Sun) that no longer exists.\n\n---\n\n### 4. `#define Reg register` — the optimization hint that became a no-op\n\n```c\n// common/os.h:329\n#define Reg register\n```\n\nUsed religiously in hot loops: `Reg unsigned char *str1` (match.c:294), `Reg int i` (hash.c:357), `Reg char *tmp` (support.c:64). **Why then:** the `register` keyword told K&amp;R and early ANSI compilers to keep a variable in a CPU register, and the `Reg` alias let you toggle it project-wide. **Why absurd now:** every compiler since roughly GCC 2.x ignores `register` for allocation (it's deprecated and removed in C++17); modern optimizers laugh at the hint. The macro exists purely to make ancient code look busy.\n\n---\n\n### 5. Hand-rolled `printf` where the function *body* is a `#include`d file\n\n```c\n// common/irc_sprintf.c:35-40\nint irc_sprintf(aClient *target, char *buf, char *format, ...)\n#include \"irc_sprintf_body.c\"\n#define IRC_SPRINTF_V 1\nint irc_vsprintf(aClient *target, char *buf, char *format, va_list ap)\n#include \"irc_sprintf_body.c\"\n```\n\nThe same `irc_sprintf_body.c` is textually `#include`d as the body of four different function signatures, toggled by `#define`s — C's answer to templates. **Why then:** to avoid duplicating a custom `printf` (supporting `%y`/`%Y` for client structs) across variants without a real generics mechanism. **Why absurd now:** a snprintf-shaped variant is `#if 0`'d out with the comment `error SN version is unsafe so far, sorry` (irc_sprintf.c:44) — they wrote their own printf, then couldn't make the bounds-checked version safe, and left it disabled.\n\n---\n\n### 6. Compiler flags to drag K&amp;R-era `cc` into the ANSI age\n\n```c\n// support/configure.in:297-326\nAC_DEFUN(IRC_SGI_CC, ...\n CC=\"$CC -cckr\" # SGI IRIX: \"compile K&amp;R\"\n...\nAC_DEFUN(IRC_HPUX_CC, ...\n CC=\"$CC -Ae\" # HP-UX: enable ANSI extensions\n```\n\n**Why then:** SGI's `cc` defaulted to pre-ANSI K&amp;R C and needed `-cckr`, while HP-UX's `cc` needed `-Ae` just to accept ANSI code. **Why absurd now:** these are workarounds for the *default dialect* of vendor compilers on IRIX and HP-UX, two commercial Unixes that are both discontinued; nobody has typed `-cckr` in anger this millennium.\n\n---\n\n### 7. Detecting whether the OS silently loses signals — by firing two and counting\n\n```c\n// support/configure.in:405-429\nmain()\n{\n (void)signal(SIGCHLD, hand);\n kill(getpid(), SIGCHLD);\n kill(getpid(), SIGCHLD);\n if (got &lt; 2)\n exit(1);\n ...\n AC_MSG_RESULT([using unreliable SystemV signal])\n AC_DEFINE([SYSV_UNRELIABLE_SIGNALS], ...)\n```\n\n**Why then:** classic System V signals reset the handler to default on delivery and could drop a second signal that arrived during handling — genuinely \"unreliable.\" **Why absurd now:** POSIX `sigaction` (reliable by mandate) has been universal since the mid-1990s; the build system still has a whole ladder of `posix_sigaction` → `bsd_sigset` → `bsd_signal` → `sysv_signal` fallbacks for a race that modern kernels cannot exhibit.\n\n---\n\n### 8. The `accept()` third-argument-type guessing game\n\n```c\n// support/configure.in:23-25\nfor ac_cv_func_accept_arg1 in 'int' 'unsigned int'; do\n for ac_cv_func_accept_arg2 in 'struct sockaddr' 'const struct sockaddr' 'void'; do\n for ac_cv_func_accept_arg3 in 'socklen_t' 'size_t' 'unsigned int' 'int'; do\n```\n\nResolved in `os.h:582-590` into `SOCK_LEN_TYPE`, with a resigned essay: *\"X/Open SPEC 1170 specifies... a size_t... only a few systems (for example AIX 4.2) follow this specification... And then POSIX changed it again to a socklen_t\"* (os.h:566-580). **Why then:** the length argument to `accept()` legitimately changed type three times across the Unix wars (int → size_t → socklen_t). **Why absurd now:** it's been `socklen_t` everywhere for 25 years; this is a monument to a standards committee flip-flop nobody remembers.\n\n---\n\n### 9. A tokenizer that speaks ISO-2022-JP escape sequences\n\n```c\n// common/support.c:49 + 78-90\n/* I doubt library strtoken knows about JIS encoding and commas. --Beeth */\n...\n#ifdef JAPANESE\n /* We have to make special case for Japanese names when comma is\n ** a separator, as they may contain it between JIS marks. --Beeth. */\n else if (pos[0] == '\\033'\n &amp;&amp; (pos[1] == '$' || pos[1] == '(')\n &amp;&amp; pos[2] == 'B')\n```\n\n**Why then:** before UTF-8 won, Japanese IRC ran on ISO-2022-JP, where a literal comma byte could appear *inside* a multibyte glyph delimited by `ESC $ B` shift sequences — so the tokenizer had to track escape state to avoid splitting mid-character. **Why absurd now:** UTF-8 is self-synchronizing precisely so this class of bug is impossible; this is a hand-written stateful parser for a text encoding the modern web has entirely abandoned.\n\n---\n\n### 10. A `truncate()` written for one beta of one dead platform\n\n```c\n// common/support.c:829-834\n/* truncate: set a file to a specified length\n * I don't know of any UNIX that doesn't have truncate, but CYGWIN32 beta18\n * doesn't have it. -krys\n * Replacement version from Dave Miller. */\nint\ttruncate(const char *path, off_t length)\n```\n\n**Why then:** someone actually tried to run an IRC server on Cygwin beta 18 on Windows, and that specific build was missing `truncate(2)`. **Why absurd now:** the comment itself admits no real Unix ever lacked this; an entire libc function was reimplemented and shipped forever to appease a *beta* build of a Windows POSIX shim from the late 1990s.\n\n---\n\n### 11. `buildm4`: message tables preprocessed by m4, and the author knew it was wrong\n\n```sh\n# ircd/buildm4:22-30\n# If only this was a perl script...*sigh*\nINCLUDE=`../support/config.guess`\nM4=$1\n/bin/rm -f $M4\negrep \"^#def[^P]*PATCHLEVEL\" ../common/patchlevel.h | \\\nsed -e 's/[^\\\"]*\\\"\\([^\\\"]*\\)\\\"/define(VERSION,\\1)/' &gt;&gt;$M4\n```\n\nMeanwhile `version.c.SH.in` is a shell script that *generates* a C source file, embedding `@SUM@ s_serv.c` checksums and a hand-parsed `date` (version.c.SH.in:24-27). **Why then:** before robust build tooling, chaining `sed` → `m4` → `sh` → `.c` was how you did code generation. **Why absurd now:** the author's own `*sigh*` comment (buildm4:22) is the punchline — a build pipeline held together with `egrep` and regex-rewritten C, whose maintainer already wished for something better in 1993.\n\n---\n\n### 12. Fossilized addresses and dead version-control keywords baked into every binary\n\nTwo artifacts appear in dozens of files at once:\n\n- **The pre-2005 Free Software Foundation address** — `write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA` appears in **74** source files (`grep -l \"675 Mass Ave\"`). The FSF moved to Franklin Street in 2005; the GPL boilerplate here is a fixed address that has bounced mail for two decades.\n- **RCS/CVS `$Id$` keyword strings** — `static const volatile char rcsid[] = \"@(#)$Id: support.c,v 1.46 2009/03/15...\"` appears in **32** files (support.c:21). The `volatile` is a deliberate trick to stop the compiler from optimizing the string out, so `what(1)` could print version info from the binary. **Why then:** RCS/CVS auto-expanded `$Id$` on checkout, and the `@(#)` prefix let SCCS's `what` tool scrape it. **Why absurd now:** the project is in **git**, which has no keyword expansion, so these strings are frozen at their final CVS revision — embalmed version numbers from a version-control system the code no longer uses.\n\n---\n\n### Honorable mentions (quotable one-liners)\n\n- **FD_SETSIZE fallback of 30** — `# define FD_SETSIZE 30` (os.h:542) for systems so old they lack the `FD_ZERO` macros; an IRC server capped at ~30 connections.\n- **AIX 3.2 kernel-header typo patch** — `/* Stupid typo in AIX 3.2's &lt;sys/stropts.h&gt;. */` then redefines `_IO` (os.h:592-599).\n- **Paul Vixie blamed by name** — `/* ...because of the way Paul Vixie majorly screws up system's include files with Bind. */` (os.h:407-409), working around BIND 8 clobbering `arpa/inet.h`.\n- **Linux shipped a \"bad\" netdb.h** — `configure` greps CPP output for `const` in `struct hostent` and sets `BAD___CONST_NETDB_H`, then os.h:149-156 `#define __const` to nothing to compile around it.\n- **The Dynix fd knob** — `#define SEQ_NOFILE 128 /* For Dynix (sequent OS) users */` (config.h.dist:814).\n- **`config.guess` is itself a fossil** — `timestamp='2004-11-12'`, so the platform-detection oracle is 20+ years stale and cannot recognize any CPU/OS released since.\n- **HP-UX `select()` takes `int*` not `fd_set*`** — `# define SELECT_FDSET_TYPE int` (os.h:544-545), guarded by a five-clause `_XPG4_EXTENDED` incantation.\n\nThe through-line: this is a portability layer built for a computing world of a dozen incompatible commercial Unixes, pre-ANSI compilers, and 8-bit-unclean libc — nearly all of which converged on POSIX + GCC/Clang + UTF-8 decades ago, leaving the abstractions as pure sediment.</result>\n<usage><subagent_tokens>71270</subagent_tokens><tool_uses>15</tool_uses><duration_ms>180170</duration_ms></usage>\n</task-notification>"},"uuid":"368bb0ad-83c9-43a9-97f4-a269eee03b77","timestamp":"2026-07-05T22:20:24.374Z","permissionMode":"auto","origin":{"kind":"task-notification"},"promptSource":"system","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 207 207 + {"parentUuid":"368bb0ad-83c9-43a9-97f4-a269eee03b77","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01BrKukQkM73p4UwMmkh25qv","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"CAIS/wEKYggPGAIqQIdYwFIQzEtpA9pczs2rQ4W2ogeaO4L1JDPJu+qOgQVybe7ApycXeiCsfbT9D5sfcoBqJkInqb4TujD8LYeG200yDmNsYXVkZS1mYWJsZS01OAFCCHRoaW5raW5nEgxM2W4WF0sFD08GSFYaDByyOeiSKuU7OCuUdiIwS3+vg+ld6/yM/GXCcGvjVVKaqSE8RowlrFmYmIk+YCIpma2X/y5O2bapWP0nLlYzKkuAqw32SDtFcp/uEoS9BgiGuZ/KvUwcDsMmwBDb9dgzXaMgqfwQNHa5EYZ5HJ3mgjfMtg0xlNII3AvMCPXrKJoIIK2ED36XA/06OMcYAQ=="}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":5716,"cache_read_input_tokens":111705,"output_tokens":178,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":5716,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":178,"cache_read_input_tokens":111705,"cache_creation_input_tokens":5716,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5716},"type":"message"}],"speed":"standard"},"diagnostics":{"cache_miss_reason":{"type":"unavailable"}}},"requestId":"req_011CcjguygWVnzrH9AzLfCzi","type":"assistant","uuid":"3c4973e1-9e18-4eea-8017-62fe8da639e8","timestamp":"2026-07-05T22:20:30.189Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 208 208 + {"parentUuid":"3c4973e1-9e18-4eea-8017-62fe8da639e8","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01BrKukQkM73p4UwMmkh25qv","type":"message","role":"assistant","content":[{"type":"text","text":"First Opus reader is back — the portability sweep found excellent material (the 300-line hand-rolled `memcmp` for pre-ANSI libcs, the Solaris 2.0–2.2 undocumented `__switch_gethostbyname` workaround, the ISO-2022-JP-aware tokenizer, the FSF's pre-2005 mailing address embalmed in 74 files).

Here's the deliverable.\n\n---\n\n# Memory-management &amp; string fossils in IRCnet ircd 2.11\n\nA ranked tour of RAM-scarcity artifacts in `var/ircd/common/` and `var/ircd/ircd/`. Every finding is a design choice that only makes sense when a server had 16–64 MB and every client structure was a line item.\n\n---\n\n## 1. The partial-struct allocation trick (`CLIENT_REMOTE_SIZE`)\nThe crown jewel. The `aClient` struct is deliberately split so remote clients get allocated **only the prefix up to the `count` field**, and the entire local-only tail (input buffer, sendQ/recvQ dbufs, socket host, password, auth fd…) is never allocated.\n\n`common/struct_def.h:577-578`:\n```c\n#define\tCLIENT_LOCAL_SIZE sizeof(aClient)\n#define\tCLIENT_REMOTE_SIZE offsetof(aClient,count)\n```\n`common/struct_def.h:530-538` — the comment marking the cut line:\n```c\n\t/*\n\t** The following fields are allocated only for local clients\n\t** ... The first of them *MUST* be the \"count\"--it is the field\n\t** to which the allocation is tied to! *Never* refer to\n\t** these fields, if (from != self).\n\t*/\n\tint\tcount;\t\t/* Amount of data in buffer */\n\tchar\tbuffer[BUFSIZE]; /* Incoming message buffer */\n```\n`ircd/list.c:92-105` — the allocator that reads the offset as a length and `malloc`s a truncated struct:\n```c\nReg\tunsigned size = CLIENT_REMOTE_SIZE;\nif (!from)\n\tsize = CLIENT_LOCAL_SIZE;\ncptr = (aClient *)MyMalloc(size);\nbzero((char *)cptr, (int)size);\n```\n- **Then:** On a hub relaying 5,000 remote users, skipping the ~600-byte local tail (a 512-byte `buffer` plus two dbuf headers, sockhost, passwd) saves multiple megabytes of otherwise-dead RAM per struct.\n- **Now:** This is undefined behavior waiting to happen — a single mis-predicated field access on a remote client reads past the allocation, and the invariant is enforced only by a scary comment. Rust makes this literally unexpressible; you'd model it as an `enum { Local(Box&lt;LocalData&gt;), Remote }` and the compiler guarantees you can't touch `LocalData` on a remote.\n\n## 2. Interior self-pointers: `name = namebuf`\nEvery client carries both a `char namebuf[NICKLEN+1]` and a `char *name` that usually points *into its own struct* — but is re-pointed at the server's or user's namebuf when the client becomes one of those.\n\n`ircd/list.c:121`: `cptr-&gt;name = cptr-&gt;namebuf;`\n`ircd/list.c:226`: `cptr-&gt;name = serv-&gt;namebuf;` (server name lives in a *different* struct)\n`common/struct_def.h:526-527`:\n```c\nchar\t*name;\t\t/* Pointer to unique name of the client */\nchar\tnamebuf[NICKLEN+1]; /* nick of the client */\n```\n- **Then:** Indirection through one pointer lets `-&gt;name` transparently follow the nick, a server name, or a masked identity without copying the string on every reference.\n- **Now:** The struct is non-movable and non-`memcpy`-able (the pointer would dangle), the pointer can outlive the buffer it aims at, and it defeats every bounds check. Rust forbids self-referential structs outright without `Pin` + `unsafe`; the borrow checker exists specifically to stop this.\n\n## 3. The `char sip[1]` struct-hack (flexible array member before C99)\n`anUser` ends with a 1-byte array that is deliberately over-allocated to hold an IPv4-or-IPv6 string.\n\n`common/struct_def.h:470-472`:\n```c\n\t\t\t\t/* sip MUST be the last in this struct!!! */\n\tchar\tsip[1];\t\t/* ip as a string, big enough for ipv6\n\t\t\t\t * allocated to real size in make_user */\n```\n`ircd/list.c:189`: `user = (anUser *)MyMalloc(sizeof(anUser) + iplen);`\n- **Then:** One allocation instead of two (struct + separate string), and IPv4 users don't pay for IPv6-sized storage — the array is sized to the *actual* address length per user.\n- **Now:** Reading `sip[5]` is formally out-of-bounds on the declared `[1]`; the whole thing rides on `MUST be the last` staying true across edits. Rust's DSTs / a trailing `[u8]` need `unsafe` and manual layout; the idiomatic answer is just `String` or `IpAddr`.\n\n## 4. `dbufbuf` sized to fit exactly one memory page\nThe dynamic-buffer pool block is hand-tuned so the struct + malloc overhead lands on a 2 KB page boundary.\n\n`common/dbuf_def.h:64-73`:\n```c\n** If it was possible, this would compile to be exactly 1 memory\n** page in size. 2048 bytes seems to be the most common size, so\n** as long as a pointer is 4 bytes, we get 2032 bytes for buffer\n** data after we take away a bit for malloc to play with. -avalon\ntypedef struct dbufbuf {\n\tstruct\tdbufbuf\t*next;\n\tchar\tdata[2032];\n} dbufbuf;\n```\n- **Then:** Matching the page size and leaving 16 bytes \"for malloc to play with\" avoids straddling pages and fragmenting the allocator — real wins when VM pages are precious.\n- **Now:** `2032` assumes 4-byte pointers (it silently mis-sizes on any 64-bit box), and the magic number is pure folklore. Rust's `BytesMut`/`Vec` sidestep the whole hand-tuning.\n\n## 5. The `dbuf` bufferpool: a preallocated freelist with byte-budget accounting\nInstead of trusting `malloc`, the server carves one big slab at boot into a linked freelist and refuses to exceed a computed pool ceiling.\n\n`common/dbuf.c:36-60` (init slab + freelist):\n```c\nu_int\tpoolsize = (BUFFERPOOL &gt; 1500000) ? BUFFERPOOL : 1500000;\ndbufbuf\t*freelist = NULL;\n...\nnb = poolsize / sizeof(dbufbuf);\nfreelist = (dbufbuf *)malloc(nb * sizeof(dbufbuf));\n```\n`common/dbuf.c:77-80` — allocation *fails on purpose* when the pool is exhausted, returning `-2` \"not fatal, go increase poolsize\":\n```c\nif (istat.is_dbufuse * DBUFSIZ &gt; poolsize)\n {\n\tistat.is_dbufuse--;\n\treturn -2;\t/* Not fatal, go back and increase poolsize */\n }\n```\n`common/struct_def.h:81-82` — the pool ceiling is a compile-time formula over `MAXCONNECTIONS`/`MAXSERVERS`.\n- **Then:** A bounded, pre-reserved pool means a flood can't OOM the box; the server sheds load (drops slow clients) instead of dying, and freelist reuse avoids `malloc` churn under high message rates.\n- **Now:** It reimplements the allocator badly (`is_dbufuse`, `is_dbufmax`, `is_dbufnow` counters all hand-maintained), and a miscount silently leaks or double-frees pool blocks. Rust would use a real arena/`bytes` crate with the accounting for free.\n\n## 6. Hand-rolled `MyMalloc` with a `\"VAVA\"` magic-byte canary\nEvery allocation is wrapped to stash the original pointer + size + a 4-byte trailer sentinel, so `MyFree`/`MyRealloc` can detect heap corruption manually.\n\n`common/support.c:557-559`:\n```c\nbcopy((char *)&amp;ret, ret, SZ_CH);\nbcopy((char *)&amp;x, ret + SZ_CH, SZ_ST);\nbcopy(\"VAVA\", ret + SZ_CHST + (int)x, 4);\n```\n`common/support.c:637-639` — the check on free:\n```c\nif (bcmp((char *)k, \"VAVA\", 4) || (j != x))\n\tdumpcore(\"MyFree %#x %ld %#x %#x\", x, i, j, ...);\n```\nPlus a global `marray[100000]` table tracking every live pointer (`support.c:561-568`).\n- **Then:** No valgrind/ASan in the '90s, so a homemade guard-byte + pointer registry was the only way to catch the double-frees and overruns that plagued a long-lived C daemon.\n- **Now:** It's a bespoke, unsynchronized, size-limited (100k entries) shadow heap that itself can corrupt memory, and `bcopy`-into-offsets defeats the type system entirely. Rust's ownership model makes the entire mechanism unnecessary.\n\n## 7. `union Link` — one intrusive node type overloaded for six pointer kinds\nA single `SLink` struct threads channel lists, invite lists, whowas chains, conf chains, and more, with a `union` payload reinterpreted by context.\n\n`common/struct_def.h:667-678`:\n```c\nstruct\tSLink\t{\n\tstruct\tSLink\t*next;\n\tunion {\n\t\taClient\t*cptr;\n\t\taChannel *chptr;\n\t\taConfItem *aconf;\n\t\taListItem *alist;\n\t\tchar\t*cp;\n\t\tint\ti;\n\t} value;\n\tint\tflags;\n};\n```\n- **Then:** One allocator (`make_link`, `list.c:517`) and one node layout for every linked list in the server — minimal code, minimal per-node overhead, no generics in C.\n- **Now:** Nothing enforces that you read back the same union arm you wrote; a `value.chptr` stored and read as `value.cptr` is a silent type confusion. Rust's tagged enums carry the discriminant and check it; an untagged `union` read is `unsafe` precisely because this is a footgun.\n\n## 8. Global mutable `sendbuf[2048]` formatted with unchecked `vsprintf`\nEvery outbound line is built in one of two shared static buffers, formatted with `vsprintf` (no size argument), and only *afterward* clamped to 512.\n\n`common/send.c:31-36`:\n```c\nstatic\tchar\tsendbuf[2048];\nstatic\tchar\tpsendbuf[2048];\nstatic\tint\tsentalong[MAXCONNECTIONS];\n```\n`common/send.c:367-376` — the overflow is structural: the write happens, *then* the length is inspected:\n```c\nlen = vsprintf(sendbuf, pattern, va);\nif (len &gt; 510)\n\tlen = 510;\nsendbuf[len++] = '\\r';\n```\n- **Then:** Two reused 2 KB scratch buffers for the whole process cost 4 KB total instead of a per-message allocation — trivially cheap and cache-friendly on a single-threaded server.\n- **Now:** `vsprintf` into a fixed buffer with attacker-influenced `%s` args is the textbook remote overflow; the `&gt; 510` check is cosmetic because the smash already occurred. And the shared global buffer makes the code fundamentally single-threaded. Rust's `write!` into a sized `String`/`ArrayString` can't overflow, and `&amp;mut` aliasing rules kill the shared-global pattern.\n\n## 9. `BUFSIZE 512` — the \"*DONT* CHANGE THIS*\" load-bearing constant\n`common/struct_def.h:57`:\n```c\n#define\tBUFSIZE\t\t512\t\t/* WARNING: *DONT* CHANGE THIS!!!! */\n```\n…one of a cluster of screaming constants (`CHIDLEN`, `SIDLEN`, `MAXMODEPARAMS` all carry the same `*DONT* CHANGE THIS!!!!` at lines 63-67).\n- **Then:** The RFC 1459 512-byte line limit is baked into hundreds of fixed `char[BUFSIZE]` stack buffers; the shout is a warning that the number is duplicated as an assumption everywhere, not a tunable.\n- **Now:** A magic number whose safety depends on grep-and-pray consistency across the tree; modern protocols (IRCv3 message tags) needed exactly this to grow and couldn't. Rust would make it a `const` the buffers derive from, checked at compile time.\n\n## 10. Manual refcounting with a magic sentinel for loop detection\n`anUser`/`aServer` blocks are shared and hand-refcounted; `free_user` decrements and, to catch double-frees, poisons the count with a specific magic number.\n\n`common/struct_def.h:443-446`: `int refcnt; /* Number of times this block is referenced ... */`\n`ircd/list.c:251-297`:\n```c\nif (--user-&gt;refcnt &lt;= 0)\n{\n\t/* XXX: Remove loop detection before 2.11.0 - jv */\n\tif (user-&gt;refcnt == -211001)\n\t{\n\t\tsendto_flag(SCH_ERROR, \"* %p free_user loop ...\");\n\t\treturn;\n\t}\n\t...\n\tuser-&gt;refcnt = -211000; /* For loop detection */\n```\n- **Then:** Shared user/server records (a user is pointed at by its client, its server's `by`, and N whowas slots) needed manual refcounts, and encoding a \"being freed\" state as `-211000` avoided adding a whole extra field per struct.\n- **Now:** A refcount that doubles as a state machine via hardcoded sentinels (`-211001`, `-211000`) is a debugging nightmare, and the `XXX: Remove ... before 2.11.0` comment reveals it shipped anyway. Rust's `Rc`/`Arc` make refcounting safe, automatic, and impossible to double-free.\n\n## 11. Byte-granular memory accounting sprinkled through the logic\nThe server tracks its own heap usage down to individual strings, with `+= strlen(x)+1` bookkeeping interleaved into every alloc/free path.\n\n`common/struct_def.h:814-844`: a wall of `u_long is_chanmem, is_hchanmem, is_cchanmem, is_awaymem, is_banmem, is_confmem, is_wwawaysmem, is_authmem …`\n`ircd/list.c:159`: `istat.is_authmem -= strlen(cptr-&gt;auth) + 1;`\n`ircd/list.c:303-304`:\n```c\nistat.is_away--;\nistat.is_awaymem -= (strlen(user-&gt;away) + 1);\n```\n- **Then:** Operators used `STATS` to watch RAM by category and tune `MAXCONNECTIONS`/pool sizes on a box where 8 MB of away-messages mattered; the server literally reported its own footprint by feature.\n- **Now:** Every one of these hand-maintained counters is a place to desync from reality (a missed `-=` on an error path silently corrupts the stats), and `strlen` on free assumes the string was never mutated. It's manual instrumentation that a modern allocator or `jemalloc` stats provide for free.\n\n## 12. Prime-sized hash tables scaled off `MAXCONNECTIONS`\nHash tables are sized to `1.75 × MAXCONNECTIONS`, then rounded *up to the next prime* by trial division at boot.\n\n`ircd/hash_def.h:30-31`:\n```c\n#define\tHASHSIZE\t((int)((float)MAXCONNECTIONS*1.75))\n#define\tCHANNELHASHSIZE\t((int)(((float)MAXCONNECTIONS*1.75)/2.0))\n```\n`ircd/hash.c:231-258` — `bigger_prime()` sieves upward by trial division:\n```c\nif (size % 2 == 0) /* Make sure it's odd because... */\n\tsize++;\nfor ( ; ; size += 2) /* ...no point checking even numbers - Core */\n```\n- **Then:** A prime modulus minimizes collisions for the cheap multiplicative string hash, and sizing off `MAXCONNECTIONS` right-sizes the table to the box's configured capacity — you don't waste a 64 K-bucket table on a 256-user leaf.\n- **Now:** Fixed at boot with no resize-under-load, tied to a compile-time max, and the collision behavior lives in a hand-hashed `%_HASHSIZE` scattered across `hash.c`. Rust's `HashMap` grows dynamically with a DoS-resistant hasher and none of this ceremony.\n\n---\n\n**Honorable mention** — the whowas history is a fixed circular buffer sized `MAXCONNECTIONS*2` with slot reuse (`ircd/whowas.c:23,37`: \"referenced like a circular loop. Should be faster and more efficient.\" / `int ww_index = 0, ww_size = MAXCONNECTIONS*2;`), and `make_client` still carries `cptr-&gt;next = NULL; /* For machines with NON-ZERO NULL pointers &gt;;) */` (`list.c:116`) — a comment defending against architectures where the null pointer isn't all-zero-bits, a portability worry that predates the modern internet as thoroughly as anything in the tree.</result>\n<usage><subagent_tokens>62121</subagent_tokens><tool_uses>25</tool_uses><duration_ms>185957</duration_ms></usage>\n</task-notification>"} 215 215 + {"type":"queue-operation","operation":"dequeue","timestamp":"2026-07-05T22:20:40.440Z","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 216 216 + {"parentUuid":"7cf8bbe5-e3e3-4768-aac0-727b8579923f","isSidechain":false,"promptId":"3afd3e3b-21f0-4cfc-a2cd-0fa3be769f09","type":"user","message":{"role":"user","content":"<task-notification>\n<task-id>acf53e5dab2e5dbe5</task-id>\n<tool-use-id>toolu_01NeYKPq2uykWuZGLnQgD1Wn</tool-use-id>\n<output-file>/tmp/claude-1000/-home-xe-Code-xeiaso-net-ircd-rs/5afb6f54-a28b-4d54-abb4-024e2406a27c/tasks/acf53e5dab2e5dbe5.output</output-file>\n<status>completed</status>\n<summary>Agent \"Dig memory/string-handling debt\" finished</summary>\n<note>A task-notification fires each time this agent stops with no live background children of its own.

Here's the deliverable.\n\n---\n\n# Memory-management &amp; string fossils in IRCnet ircd 2.11\n\nA ranked tour of RAM-scarcity artifacts in `var/ircd/common/` and `var/ircd/ircd/`. Every finding is a design choice that only makes sense when a server had 16–64 MB and every client structure was a line item.\n\n---\n\n## 1. The partial-struct allocation trick (`CLIENT_REMOTE_SIZE`)\nThe crown jewel. The `aClient` struct is deliberately split so remote clients get allocated **only the prefix up to the `count` field**, and the entire local-only tail (input buffer, sendQ/recvQ dbufs, socket host, password, auth fd…) is never allocated.\n\n`common/struct_def.h:577-578`:\n```c\n#define\tCLIENT_LOCAL_SIZE sizeof(aClient)\n#define\tCLIENT_REMOTE_SIZE offsetof(aClient,count)\n```\n`common/struct_def.h:530-538` — the comment marking the cut line:\n```c\n\t/*\n\t** The following fields are allocated only for local clients\n\t** ... The first of them *MUST* be the \"count\"--it is the field\n\t** to which the allocation is tied to! *Never* refer to\n\t** these fields, if (from != self).\n\t*/\n\tint\tcount;\t\t/* Amount of data in buffer */\n\tchar\tbuffer[BUFSIZE]; /* Incoming message buffer */\n```\n`ircd/list.c:92-105` — the allocator that reads the offset as a length and `malloc`s a truncated struct:\n```c\nReg\tunsigned size = CLIENT_REMOTE_SIZE;\nif (!from)\n\tsize = CLIENT_LOCAL_SIZE;\ncptr = (aClient *)MyMalloc(size);\nbzero((char *)cptr, (int)size);\n```\n- **Then:** On a hub relaying 5,000 remote users, skipping the ~600-byte local tail (a 512-byte `buffer` plus two dbuf headers, sockhost, passwd) saves multiple megabytes of otherwise-dead RAM per struct.\n- **Now:** This is undefined behavior waiting to happen — a single mis-predicated field access on a remote client reads past the allocation, and the invariant is enforced only by a scary comment. Rust makes this literally unexpressible; you'd model it as an `enum { Local(Box&lt;LocalData&gt;), Remote }` and the compiler guarantees you can't touch `LocalData` on a remote.\n\n## 2. Interior self-pointers: `name = namebuf`\nEvery client carries both a `char namebuf[NICKLEN+1]` and a `char *name` that usually points *into its own struct* — but is re-pointed at the server's or user's namebuf when the client becomes one of those.\n\n`ircd/list.c:121`: `cptr-&gt;name = cptr-&gt;namebuf;`\n`ircd/list.c:226`: `cptr-&gt;name = serv-&gt;namebuf;` (server name lives in a *different* struct)\n`common/struct_def.h:526-527`:\n```c\nchar\t*name;\t\t/* Pointer to unique name of the client */\nchar\tnamebuf[NICKLEN+1]; /* nick of the client */\n```\n- **Then:** Indirection through one pointer lets `-&gt;name` transparently follow the nick, a server name, or a masked identity without copying the string on every reference.\n- **Now:** The struct is non-movable and non-`memcpy`-able (the pointer would dangle), the pointer can outlive the buffer it aims at, and it defeats every bounds check. Rust forbids self-referential structs outright without `Pin` + `unsafe`; the borrow checker exists specifically to stop this.\n\n## 3. The `char sip[1]` struct-hack (flexible array member before C99)\n`anUser` ends with a 1-byte array that is deliberately over-allocated to hold an IPv4-or-IPv6 string.\n\n`common/struct_def.h:470-472`:\n```c\n\t\t\t\t/* sip MUST be the last in this struct!!! */\n\tchar\tsip[1];\t\t/* ip as a string, big enough for ipv6\n\t\t\t\t * allocated to real size in make_user */\n```\n`ircd/list.c:189`: `user = (anUser *)MyMalloc(sizeof(anUser) + iplen);`\n- **Then:** One allocation instead of two (struct + separate string), and IPv4 users don't pay for IPv6-sized storage — the array is sized to the *actual* address length per user.\n- **Now:** Reading `sip[5]` is formally out-of-bounds on the declared `[1]`; the whole thing rides on `MUST be the last` staying true across edits. Rust's DSTs / a trailing `[u8]` need `unsafe` and manual layout; the idiomatic answer is just `String` or `IpAddr`.\n\n## 4. `dbufbuf` sized to fit exactly one memory page\nThe dynamic-buffer pool block is hand-tuned so the struct + malloc overhead lands on a 2 KB page boundary.\n\n`common/dbuf_def.h:64-73`:\n```c\n** If it was possible, this would compile to be exactly 1 memory\n** page in size. 2048 bytes seems to be the most common size, so\n** as long as a pointer is 4 bytes, we get 2032 bytes for buffer\n** data after we take away a bit for malloc to play with. -avalon\ntypedef struct dbufbuf {\n\tstruct\tdbufbuf\t*next;\n\tchar\tdata[2032];\n} dbufbuf;\n```\n- **Then:** Matching the page size and leaving 16 bytes \"for malloc to play with\" avoids straddling pages and fragmenting the allocator — real wins when VM pages are precious.\n- **Now:** `2032` assumes 4-byte pointers (it silently mis-sizes on any 64-bit box), and the magic number is pure folklore. Rust's `BytesMut`/`Vec` sidestep the whole hand-tuning.\n\n## 5. The `dbuf` bufferpool: a preallocated freelist with byte-budget accounting\nInstead of trusting `malloc`, the server carves one big slab at boot into a linked freelist and refuses to exceed a computed pool ceiling.\n\n`common/dbuf.c:36-60` (init slab + freelist):\n```c\nu_int\tpoolsize = (BUFFERPOOL &gt; 1500000) ? BUFFERPOOL : 1500000;\ndbufbuf\t*freelist = NULL;\n...\nnb = poolsize / sizeof(dbufbuf);\nfreelist = (dbufbuf *)malloc(nb * sizeof(dbufbuf));\n```\n`common/dbuf.c:77-80` — allocation *fails on purpose* when the pool is exhausted, returning `-2` \"not fatal, go increase poolsize\":\n```c\nif (istat.is_dbufuse * DBUFSIZ &gt; poolsize)\n {\n\tistat.is_dbufuse--;\n\treturn -2;\t/* Not fatal, go back and increase poolsize */\n }\n```\n`common/struct_def.h:81-82` — the pool ceiling is a compile-time formula over `MAXCONNECTIONS`/`MAXSERVERS`.\n- **Then:** A bounded, pre-reserved pool means a flood can't OOM the box; the server sheds load (drops slow clients) instead of dying, and freelist reuse avoids `malloc` churn under high message rates.\n- **Now:** It reimplements the allocator badly (`is_dbufuse`, `is_dbufmax`, `is_dbufnow` counters all hand-maintained), and a miscount silently leaks or double-frees pool blocks. Rust would use a real arena/`bytes` crate with the accounting for free.\n\n## 6. Hand-rolled `MyMalloc` with a `\"VAVA\"` magic-byte canary\nEvery allocation is wrapped to stash the original pointer + size + a 4-byte trailer sentinel, so `MyFree`/`MyRealloc` can detect heap corruption manually.\n\n`common/support.c:557-559`:\n```c\nbcopy((char *)&amp;ret, ret, SZ_CH);\nbcopy((char *)&amp;x, ret + SZ_CH, SZ_ST);\nbcopy(\"VAVA\", ret + SZ_CHST + (int)x, 4);\n```\n`common/support.c:637-639` — the check on free:\n```c\nif (bcmp((char *)k, \"VAVA\", 4) || (j != x))\n\tdumpcore(\"MyFree %#x %ld %#x %#x\", x, i, j, ...);\n```\nPlus a global `marray[100000]` table tracking every live pointer (`support.c:561-568`).\n- **Then:** No valgrind/ASan in the '90s, so a homemade guard-byte + pointer registry was the only way to catch the double-frees and overruns that plagued a long-lived C daemon.\n- **Now:** It's a bespoke, unsynchronized, size-limited (100k entries) shadow heap that itself can corrupt memory, and `bcopy`-into-offsets defeats the type system entirely. Rust's ownership model makes the entire mechanism unnecessary.\n\n## 7. `union Link` — one intrusive node type overloaded for six pointer kinds\nA single `SLink` struct threads channel lists, invite lists, whowas chains, conf chains, and more, with a `union` payload reinterpreted by context.\n\n`common/struct_def.h:667-678`:\n```c\nstruct\tSLink\t{\n\tstruct\tSLink\t*next;\n\tunion {\n\t\taClient\t*cptr;\n\t\taChannel *chptr;\n\t\taConfItem *aconf;\n\t\taListItem *alist;\n\t\tchar\t*cp;\n\t\tint\ti;\n\t} value;\n\tint\tflags;\n};\n```\n- **Then:** One allocator (`make_link`, `list.c:517`) and one node layout for every linked list in the server — minimal code, minimal per-node overhead, no generics in C.\n- **Now:** Nothing enforces that you read back the same union arm you wrote; a `value.chptr` stored and read as `value.cptr` is a silent type confusion. Rust's tagged enums carry the discriminant and check it; an untagged `union` read is `unsafe` precisely because this is a footgun.\n\n## 8. Global mutable `sendbuf[2048]` formatted with unchecked `vsprintf`\nEvery outbound line is built in one of two shared static buffers, formatted with `vsprintf` (no size argument), and only *afterward* clamped to 512.\n\n`common/send.c:31-36`:\n```c\nstatic\tchar\tsendbuf[2048];\nstatic\tchar\tpsendbuf[2048];\nstatic\tint\tsentalong[MAXCONNECTIONS];\n```\n`common/send.c:367-376` — the overflow is structural: the write happens, *then* the length is inspected:\n```c\nlen = vsprintf(sendbuf, pattern, va);\nif (len &gt; 510)\n\tlen = 510;\nsendbuf[len++] = '\\r';\n```\n- **Then:** Two reused 2 KB scratch buffers for the whole process cost 4 KB total instead of a per-message allocation — trivially cheap and cache-friendly on a single-threaded server.\n- **Now:** `vsprintf` into a fixed buffer with attacker-influenced `%s` args is the textbook remote overflow; the `&gt; 510` check is cosmetic because the smash already occurred. And the shared global buffer makes the code fundamentally single-threaded. Rust's `write!` into a sized `String`/`ArrayString` can't overflow, and `&amp;mut` aliasing rules kill the shared-global pattern.\n\n## 9. `BUFSIZE 512` — the \"*DONT* CHANGE THIS*\" load-bearing constant\n`common/struct_def.h:57`:\n```c\n#define\tBUFSIZE\t\t512\t\t/* WARNING: *DONT* CHANGE THIS!!!! */\n```\n…one of a cluster of screaming constants (`CHIDLEN`, `SIDLEN`, `MAXMODEPARAMS` all carry the same `*DONT* CHANGE THIS!!!!` at lines 63-67).\n- **Then:** The RFC 1459 512-byte line limit is baked into hundreds of fixed `char[BUFSIZE]` stack buffers; the shout is a warning that the number is duplicated as an assumption everywhere, not a tunable.\n- **Now:** A magic number whose safety depends on grep-and-pray consistency across the tree; modern protocols (IRCv3 message tags) needed exactly this to grow and couldn't. Rust would make it a `const` the buffers derive from, checked at compile time.\n\n## 10. Manual refcounting with a magic sentinel for loop detection\n`anUser`/`aServer` blocks are shared and hand-refcounted; `free_user` decrements and, to catch double-frees, poisons the count with a specific magic number.\n\n`common/struct_def.h:443-446`: `int refcnt; /* Number of times this block is referenced ... */`\n`ircd/list.c:251-297`:\n```c\nif (--user-&gt;refcnt &lt;= 0)\n{\n\t/* XXX: Remove loop detection before 2.11.0 - jv */\n\tif (user-&gt;refcnt == -211001)\n\t{\n\t\tsendto_flag(SCH_ERROR, \"* %p free_user loop ...\");\n\t\treturn;\n\t}\n\t...\n\tuser-&gt;refcnt = -211000; /* For loop detection */\n```\n- **Then:** Shared user/server records (a user is pointed at by its client, its server's `by`, and N whowas slots) needed manual refcounts, and encoding a \"being freed\" state as `-211000` avoided adding a whole extra field per struct.\n- **Now:** A refcount that doubles as a state machine via hardcoded sentinels (`-211001`, `-211000`) is a debugging nightmare, and the `XXX: Remove ... before 2.11.0` comment reveals it shipped anyway. Rust's `Rc`/`Arc` make refcounting safe, automatic, and impossible to double-free.\n\n## 11. Byte-granular memory accounting sprinkled through the logic\nThe server tracks its own heap usage down to individual strings, with `+= strlen(x)+1` bookkeeping interleaved into every alloc/free path.\n\n`common/struct_def.h:814-844`: a wall of `u_long is_chanmem, is_hchanmem, is_cchanmem, is_awaymem, is_banmem, is_confmem, is_wwawaysmem, is_authmem …`\n`ircd/list.c:159`: `istat.is_authmem -= strlen(cptr-&gt;auth) + 1;`\n`ircd/list.c:303-304`:\n```c\nistat.is_away--;\nistat.is_awaymem -= (strlen(user-&gt;away) + 1);\n```\n- **Then:** Operators used `STATS` to watch RAM by category and tune `MAXCONNECTIONS`/pool sizes on a box where 8 MB of away-messages mattered; the server literally reported its own footprint by feature.\n- **Now:** Every one of these hand-maintained counters is a place to desync from reality (a missed `-=` on an error path silently corrupts the stats), and `strlen` on free assumes the string was never mutated. It's manual instrumentation that a modern allocator or `jemalloc` stats provide for free.\n\n## 12. Prime-sized hash tables scaled off `MAXCONNECTIONS`\nHash tables are sized to `1.75 × MAXCONNECTIONS`, then rounded *up to the next prime* by trial division at boot.\n\n`ircd/hash_def.h:30-31`:\n```c\n#define\tHASHSIZE\t((int)((float)MAXCONNECTIONS*1.75))\n#define\tCHANNELHASHSIZE\t((int)(((float)MAXCONNECTIONS*1.75)/2.0))\n```\n`ircd/hash.c:231-258` — `bigger_prime()` sieves upward by trial division:\n```c\nif (size % 2 == 0) /* Make sure it's odd because... */\n\tsize++;\nfor ( ; ; size += 2) /* ...no point checking even numbers - Core */\n```\n- **Then:** A prime modulus minimizes collisions for the cheap multiplicative string hash, and sizing off `MAXCONNECTIONS` right-sizes the table to the box's configured capacity — you don't waste a 64 K-bucket table on a 256-user leaf.\n- **Now:** Fixed at boot with no resize-under-load, tied to a compile-time max, and the collision behavior lives in a hand-hashed `%_HASHSIZE` scattered across `hash.c`. Rust's `HashMap` grows dynamically with a DoS-resistant hasher and none of this ceremony.\n\n---\n\n**Honorable mention** — the whowas history is a fixed circular buffer sized `MAXCONNECTIONS*2` with slot reuse (`ircd/whowas.c:23,37`: \"referenced like a circular loop. Should be faster and more efficient.\" / `int ww_index = 0, ww_size = MAXCONNECTIONS*2;`), and `make_client` still carries `cptr-&gt;next = NULL; /* For machines with NON-ZERO NULL pointers &gt;;) */` (`list.c:116`) — a comment defending against architectures where the null pointer isn't all-zero-bits, a portability worry that predates the modern internet as thoroughly as anything in the tree.</result>\n<usage><subagent_tokens>62121</subagent_tokens><tool_uses>25</tool_uses><duration_ms>185957</duration_ms></usage>\n</task-notification>"},"uuid":"e8eff0b4-1080-4045-8ed9-79cce69d83d7","timestamp":"2026-07-05T22:20:40.453Z","permissionMode":"auto","origin":{"kind":"task-notification"},"promptSource":"system","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 217 217 + {"parentUuid":"e8eff0b4-1080-4045-8ed9-79cce69d83d7","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01XKkkKNAe9xwVV5sw37R3x9","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"CAISlwIKYggPGAIqQM7nrUVE37gha8EocBBarayCwRkh7fzesSHjIpIBJeAUVLflXbwTPatIhiuJ+XrB5xYGyb8apIxfoILwggg1rZUyDmNsYXVkZS1mYWJsZS01OAFCCHRoaW5raW5nEgyrJzUo6VVDakTZYf4aDJ9uU70cwfPnvRBG6CIwBdf5VNwXf232k9PVpqMfYpDN5m6f+MCeqYSL9mJPBJSC1S6ROTIWMReEIA3OGhN0KmMP79Lq/2V32GxFcV81jWWzmbEKmWjSLXaqh7nhpeR/MDZNbCCf7MFiuJkplySnmPsLngkNKEoTJq+T1XU1lhsCohHVrhxA8NbOZPV6ChNNSlqV7cO1bLTRQBKnJisjusOuyVcYAQ=="}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":6471,"cache_read_input_tokens":117421,"output_tokens":209,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":6471,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":209,"cache_read_input_tokens":117421,"cache_creation_input_tokens":6471,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":6471},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjgwATSKWTd4UnLjKwzT","type":"assistant","uuid":"9bf5b57d-5800-474a-95ce-40224718238a","timestamp":"2026-07-05T22:20:48.702Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 218 218 + {"parentUuid":"9bf5b57d-5800-474a-95ce-40224718238a","isSidechain":false,"message":{"model":"claude-fable-5","id":"msg_01XKkkKNAe9xwVV5sw37R3x9","type":"message","role":"assistant","content":[{"type":"text","text":"Second reader is back — the memory-scarcity sweep landed the crown jewels (`CLIENT_REMOTE_SIZE` partial-struct allocation, the `\"VAVA\"` heap canary in a homemade `MyMalloc`, `vsprintf` into a shared global buffer with the length check *after* the write, the dbuf block hand-sized to a 2KB page assuming 4-byte pointers, and the refcount that doubles as a state machine via the magic value `-211000`).

Here is the deliverable.\n\n---\n\n# IRCnet ircd 2.11: fossils of a pre-hostile internet\n\nA ranked tour of the most vivid networking assumptions baked into `var/ircd/`, each dead on arrival in the modern internet. All paths relative to `/home/xe/Code/xeiaso.net/ircd.rs/var/ircd/`.\n\n---\n\n**1. The default server holds 50 connections, total. Recompile to grow.**\n`support/config.h.dist:150` — `#define MAXCONNECTIONS 50`, with the comment (`:141`): *\"1 server = 1 connection, 1 user = 1 connection. ... If you have a lot of server connections, it may be worth splitting the load over 2 or more servers.\"* This isn't a runtime tunable — it's a compile-time constant that sizes every core data structure: `aClient *local[MAXCONNECTIONS]` (`s_bsd.c:51`), the hash tables (`hash_def.h:30`, `HASHSIZE = MAXCONNECTIONS*1.75`), whowas history, and the poll array `struct pollfd poll_fdarray[MAXCONNECTIONS]` allocated on the stack (`s_bsd.c:2038`). Change your capacity and you rebuild the daemon.\n- *1990s worldview:* A server is a fixed-size appliance on a known machine; if you need scale, you add another university's box to the mesh.\n- *Why it's dead:* Modern services autoscale to millions of concurrent sockets on one process; \"recompile to accept more users\" is unthinkable when demand is elastic and adversarial.\n\n**2. One `select()`/`poll()` thread is the entire server.**\n`s_bsd.c:2209` — `nfds = select(highfd + 1, ...)` (or `poll()` at `:2212`), the single loop that multiplexes clients, server links, the resolver socket, the UDP ping socket, and the iauth pipe. `s_bsd.c:2227`: `restart(\"too many select()/poll() errors\")` — the server literally restarts itself if the one loop wedges. The fd-limit check `if (limit.rlim_max &lt; MAXCONNECTIONS)` bails with *\"Fix MAXCONNECTIONS and recompile\"* (`s_bsd.c:688-694`).\n- *1990s worldview:* CPUs are single-core, connections are few and slow, and one event loop over a handful of fds is plenty.\n- *Why it's dead:* `select()` is O(n) over an `FD_SETSIZE`-capped bitmap; the entire epoll/kqueue/io_uring/thread-pool lineage exists precisely because this model collapses past a few thousand sockets.\n\n**3. It ships its own copy of the 1985 Berkeley BIND resolver.**\n`ircd/res_mkquery.c` opens with *\"++Copyright++ 1985, 1993 / The Regents of the University of California\"* — this is literally vendored BIND source. Alongside it: `res.c`, `res_comp.c`, `res_init.c`, `nameser_def.h`, `resolv_def.h`. The reason is in `res.c:305`: *\"sends msg to all nameservers found in the 'ircd_res' structure ... We will get responses which arent needed but is easier than checking.\"* The daemon speaks raw DNS-over-UDP to your `resolv.conf` nameservers itself, asynchronously, to keep lookups out of the blocking `select()` loop.\n- *1990s worldview:* The libc `gethostbyname()` blocks, threads barely exist, so to avoid stalling the one event loop you fork the OS resolver into your address space and drive UDP query packets by hand.\n- *Why it's dead:* Async DNS is a solved library problem (c-ares, getaddrinfo_a, every async runtime); shipping — and having to security-patch — a private fork of BIND inside a chat server is now an obvious liability, not a convenience.\n\n**4. Authentication is \"ask the remote host who you are\" (RFC 1413 ident).**\n`s_auth.c:528` `start_auth()` opens a socket back to the connecting client's port 113 (`them.SIN_PORT = htons(113)`, `:612`), sends `\"%u , %u\\r\\n\"` (their port, our port; `send_authports`, `:685`), and whatever string comes back *becomes the username* — `cptr-&gt;auth = mystrdup(ruser)` then `cptr-&gt;flags |= FLAGS_GOTID` (`s_auth.c:792-795`). The remote machine self-reports the identity of its own user, and the IRC server believes it.\n- *1990s worldview:* Every client is a shell account on a multi-user Unix box run by a trustworthy sysadmin, so that box's identd is an authoritative source of truth about who's behind the socket.\n- *Why it's dead:* Clients are single-user laptops and phones behind NAT/CGNAT; nobody runs identd, and if they did it'd be attacker-controlled — trusting a remote host to authenticate itself is a textbook anti-pattern now.\n\n**5. Server links are authenticated by a plaintext password string-compare.**\n`s_conf.c:575` — `if (!BadPtr(aconf-&gt;passwd) &amp;&amp; !StrEq(cptr-&gt;passwd, aconf-&gt;passwd))`, where `StrEq(x,y)` is just `(!strcmp((x),(y)))` (`common/struct_def.h:872`). Server-to-server is the same: `s_serv.c:958` `if (*aconf-&gt;passwd &amp;&amp; !StrEq(aconf-&gt;passwd, encr))`. The single \"upgrade\" is an optional `#ifdef CRYPT_LINK_PASSWORD` (`s_serv.c:929`) that runs the password through Unix `crypt()` — 1970s DES, `extern char *crypt();` (`:934`).\n- *1990s worldview:* Servers are peers among a small club of university/research admins who trade a shared secret over a trusted back channel; a matching string is proof of a trusted operator.\n- *Why it's dead:* There's no mutual auth, no key exchange, no forward secrecy — a plaintext password (or DES crypt) on the wire is what mutual-TLS and cert-pinned mesh links replaced entirely.\n\n**6. There is no TLS. Encryption is somebody else's stunnel.**\nNo OpenSSL, no native crypto anywhere in `ircd/`. The only \"TLS\" is `s_auth.c:582`: *\"// Check if a source IP has been set in P-Line (usually if an SSL proxy is used)\"* — a `PFLAG_TLS` port flag (`s_conf.c:203`) that just tells the daemon to trust a `source_ip` handed to it by an external SSL-terminating proxy sitting in front. The IRC protocol itself is plaintext on the wire, forever.\n- *1990s worldview:* The network is a friendly academic backbone; eavesdropping and MITM aren't part of the threat model, so wrapping the transport in crypto is out of scope.\n- *Why it's dead:* Encryption is now table stakes; a protocol daemon that can't speak TLS and instead delegates it to a bolted-on proxy (whose IP it then blindly trusts) is a relic of pre-Snowden, pre-commercial-ISP networking.\n\n**7. UDP \"ping\" packets to choose which server to link.**\n`s_bsd.c:2967` `setup_ping()` opens a `SOCK_DGRAM` socket; `send_ping()` (`:3027`) fires `PING_CPING` datagrams at peer servers and `check_ping()` (`:3068`) times the round trip — `rtt = (tv.tv_sec - pi.pi_tv.tv_sec)*1000 + ...` — then computes a link preference with `d = pow(d, 20.0)` weighting packet loss and stores `aconf-&gt;pref` (`s_bsd.c:3105`). Servers probe each other over raw UDP to rank link quality before auto-connecting.\n- *1990s worldview:* Peer servers are directly reachable at fixed IPs, UDP flows freely between them, and hand-rolled RTT sampling is a reasonable way to pick the best backbone path.\n- *Why it's dead:* Firewalls, NAT, and stateful middleboxes drop unsolicited UDP; nobody hand-measures link RTT to pick peers when anycast, BGP, and managed overlays do routing — and an open UDP port that mutates connection logic is now an amplification/attack surface.\n\n**8. SUMMON: the server pages users logged into its Unix host.**\n`s_serv.c:1489` `m_summon()` — under `#ifdef ENABLE_SUMMON` it does `utmp_open()` / `utmp_read()` (`:1522`, `:1530`) to scan the machine's login records, `stat(\"/dev/%s\", ...)` a user's tty (`:1552`), and physically write to their terminal to summon them into IRC. Comment at `s_serv.c:1540`: *\"one we find in utmp. 10/9/90 Spike@world.std.com (loosely based on Jim Frost jimf@saber.com code).\"* Its sibling `USERS` (`m_users`, `s_serv_ext.h:44`) lists who's logged into the host.\n- *1990s worldview:* IRC users *are* shell accounts on the very Unix machine running ircd, so \"go find user bob in utmp and echo to his tty\" is a coherent feature.\n- *Why it's dead:* Clients haven't been shell users on the server host for 25+ years; the command is a security hole (host-user enumeration + tty write) that's been compiled off by default, a fossilized assumption that IRC and Unix logins were the same population.\n\n**9. iauth: a whole child process to hide blocking lookups from the event loop.**\n`iauth/iauth.c` is a separate program the ircd talks to over a pipe (`adfd`, `s_auth.c:590` `sendto_iauth(abuf)`), whose entire reason to exist is that the single `select()` loop cannot afford to block on the slow, hostile checks it performs. Its modules are a museum of 1990s abuse vectors: `mod_socks.c` and `mod_webproxy.c` *connect back to the joining client* to probe for open proxies — `fd = tcp_connect(cldata[cl].ourip, cldata[cl].itsip, SOCKSPORT, ...)` (`mod_socks.c:60`), caching results as `0 = no proxy, 1 = open proxy` (`:41`); `mod_rfc931.c` re-implements ident; `mod_dnsbl.c` does DNS blocklist lookups.\n- *1990s worldview:* Blocking work must be exiled to a helper process because threads aren't an option, and the main abuse to defend against is misconfigured open SOCKS relays.\n- *Why it's dead:* Async runtimes make the \"fork a child to avoid blocking\" architecture obsolete, and actively port-scanning every connecting client for open proxies would today read as hostile behavior, not due diligence.\n\n**10. Access control trusts reverse-DNS hostnames, and K-lines ban by hostname.**\n`s_bsd.c:2912` `check_init()` resolves the server's own name via `gethostbyname()` (`:2923`), and throughout, client access (I-lines/K-lines) is matched against the *resolved hostname* returned by the client's PTR record. K-line comments/reasons are stored in `aconf-&gt;passwd` and matched by `match(tmp-&gt;passwd, ...)` glob on hostname (`s_conf.c:2242`). The comment at `s_bsd.c:2910` — *\"If hostname gives another name than cname, then check if there is a CNAME record ... accept cname as our name. meLazy\"* — captures the casual trust in whatever DNS says.\n- *1990s worldview:* A hostname is a stable, honest identifier assigned by a trustworthy admin, so glob-matching on `*.mit.edu` is a meaningful access rule.\n- *Why it's dead:* Reverse DNS is attacker-controllable and near-meaningless behind CGNAT/cloud PTR records; identity-by-hostname was replaced by SASL, accounts, and cryptographic auth because DNS trust is forgeable.\n\n**11. IPv6 was retrofitted as `#ifdef` scar tissue over an IPv4 skeleton.**\nThe v4-vs-v6 seams are everywhere: 54 `INET6`/`s6_addr`/`IN_ADDR` hits in `s_bsd.c` alone, 48 in `res.c`, plus `s_auth.c` and `s_conf.c`.

All paths relative to `/home/xe/Code/xeiaso.net/ircd.rs/var/ircd/`.\n\n---\n\n**1. The default server holds 50 connections, total. Recompile to grow.**\n`support/config.h.dist:150` — `#define MAXCONNECTIONS 50`, with the comment (`:141`): *\"1 server = 1 connection, 1 user = 1 connection. ... If you have a lot of server connections, it may be worth splitting the load over 2 or more servers.\"* This isn't a runtime tunable — it's a compile-time constant that sizes every core data structure: `aClient *local[MAXCONNECTIONS]` (`s_bsd.c:51`), the hash tables (`hash_def.h:30`, `HASHSIZE = MAXCONNECTIONS*1.75`), whowas history, and the poll array `struct pollfd poll_fdarray[MAXCONNECTIONS]` allocated on the stack (`s_bsd.c:2038`). Change your capacity and you rebuild the daemon.\n- *1990s worldview:* A server is a fixed-size appliance on a known machine; if you need scale, you add another university's box to the mesh.\n- *Why it's dead:* Modern services autoscale to millions of concurrent sockets on one process; \"recompile to accept more users\" is unthinkable when demand is elastic and adversarial.\n\n**2. One `select()`/`poll()` thread is the entire server.**\n`s_bsd.c:2209` — `nfds = select(highfd + 1, ...)` (or `poll()` at `:2212`), the single loop that multiplexes clients, server links, the resolver socket, the UDP ping socket, and the iauth pipe. `s_bsd.c:2227`: `restart(\"too many select()/poll() errors\")` — the server literally restarts itself if the one loop wedges. The fd-limit check `if (limit.rlim_max &lt; MAXCONNECTIONS)` bails with *\"Fix MAXCONNECTIONS and recompile\"* (`s_bsd.c:688-694`).\n- *1990s worldview:* CPUs are single-core, connections are few and slow, and one event loop over a handful of fds is plenty.\n- *Why it's dead:* `select()` is O(n) over an `FD_SETSIZE`-capped bitmap; the entire epoll/kqueue/io_uring/thread-pool lineage exists precisely because this model collapses past a few thousand sockets.\n\n**3. It ships its own copy of the 1985 Berkeley BIND resolver.**\n`ircd/res_mkquery.c` opens with *\"++Copyright++ 1985, 1993 / The Regents of the University of California\"* — this is literally vendored BIND source. Alongside it: `res.c`, `res_comp.c`, `res_init.c`, `nameser_def.h`, `resolv_def.h`. The reason is in `res.c:305`: *\"sends msg to all nameservers found in the 'ircd_res' structure ... We will get responses which arent needed but is easier than checking.\"* The daemon speaks raw DNS-over-UDP to your `resolv.conf` nameservers itself, asynchronously, to keep lookups out of the blocking `select()` loop.\n- *1990s worldview:* The libc `gethostbyname()` blocks, threads barely exist, so to avoid stalling the one event loop you fork the OS resolver into your address space and drive UDP query packets by hand.\n- *Why it's dead:* Async DNS is a solved library problem (c-ares, getaddrinfo_a, every async runtime); shipping — and having to security-patch — a private fork of BIND inside a chat server is now an obvious liability, not a convenience.\n\n**4. Authentication is \"ask the remote host who you are\" (RFC 1413 ident).**\n`s_auth.c:528` `start_auth()` opens a socket back to the connecting client's port 113 (`them.SIN_PORT = htons(113)`, `:612`), sends `\"%u , %u\\r\\n\"` (their port, our port; `send_authports`, `:685`), and whatever string comes back *becomes the username* — `cptr-&gt;auth = mystrdup(ruser)` then `cptr-&gt;flags |= FLAGS_GOTID` (`s_auth.c:792-795`). The remote machine self-reports the identity of its own user, and the IRC server believes it.\n- *1990s worldview:* Every client is a shell account on a multi-user Unix box run by a trustworthy sysadmin, so that box's identd is an authoritative source of truth about who's behind the socket.\n- *Why it's dead:* Clients are single-user laptops and phones behind NAT/CGNAT; nobody runs identd, and if they did it'd be attacker-controlled — trusting a remote host to authenticate itself is a textbook anti-pattern now.\n\n**5. Server links are authenticated by a plaintext password string-compare.**\n`s_conf.c:575` — `if (!BadPtr(aconf-&gt;passwd) &amp;&amp; !StrEq(cptr-&gt;passwd, aconf-&gt;passwd))`, where `StrEq(x,y)` is just `(!strcmp((x),(y)))` (`common/struct_def.h:872`). Server-to-server is the same: `s_serv.c:958` `if (*aconf-&gt;passwd &amp;&amp; !StrEq(aconf-&gt;passwd, encr))`. The single \"upgrade\" is an optional `#ifdef CRYPT_LINK_PASSWORD` (`s_serv.c:929`) that runs the password through Unix `crypt()` — 1970s DES, `extern char *crypt();` (`:934`).\n- *1990s worldview:* Servers are peers among a small club of university/research admins who trade a shared secret over a trusted back channel; a matching string is proof of a trusted operator.\n- *Why it's dead:* There's no mutual auth, no key exchange, no forward secrecy — a plaintext password (or DES crypt) on the wire is what mutual-TLS and cert-pinned mesh links replaced entirely.\n\n**6. There is no TLS. Encryption is somebody else's stunnel.**\nNo OpenSSL, no native crypto anywhere in `ircd/`. The only \"TLS\" is `s_auth.c:582`: *\"// Check if a source IP has been set in P-Line (usually if an SSL proxy is used)\"* — a `PFLAG_TLS` port flag (`s_conf.c:203`) that just tells the daemon to trust a `source_ip` handed to it by an external SSL-terminating proxy sitting in front. The IRC protocol itself is plaintext on the wire, forever.\n- *1990s worldview:* The network is a friendly academic backbone; eavesdropping and MITM aren't part of the threat model, so wrapping the transport in crypto is out of scope.\n- *Why it's dead:* Encryption is now table stakes; a protocol daemon that can't speak TLS and instead delegates it to a bolted-on proxy (whose IP it then blindly trusts) is a relic of pre-Snowden, pre-commercial-ISP networking.\n\n**7. UDP \"ping\" packets to choose which server to link.**\n`s_bsd.c:2967` `setup_ping()` opens a `SOCK_DGRAM` socket; `send_ping()` (`:3027`) fires `PING_CPING` datagrams at peer servers and `check_ping()` (`:3068`) times the round trip — `rtt = (tv.tv_sec - pi.pi_tv.tv_sec)*1000 + ...` — then computes a link preference with `d = pow(d, 20.0)` weighting packet loss and stores `aconf-&gt;pref` (`s_bsd.c:3105`). Servers probe each other over raw UDP to rank link quality before auto-connecting.\n- *1990s worldview:* Peer servers are directly reachable at fixed IPs, UDP flows freely between them, and hand-rolled RTT sampling is a reasonable way to pick the best backbone path.\n- *Why it's dead:* Firewalls, NAT, and stateful middleboxes drop unsolicited UDP; nobody hand-measures link RTT to pick peers when anycast, BGP, and managed overlays do routing — and an open UDP port that mutates connection logic is now an amplification/attack surface.\n\n**8. SUMMON: the server pages users logged into its Unix host.**\n`s_serv.c:1489` `m_summon()` — under `#ifdef ENABLE_SUMMON` it does `utmp_open()` / `utmp_read()` (`:1522`, `:1530`) to scan the machine's login records, `stat(\"/dev/%s\", ...)` a user's tty (`:1552`), and physically write to their terminal to summon them into IRC. Comment at `s_serv.c:1540`: *\"one we find in utmp. 10/9/90 Spike@world.std.com (loosely based on Jim Frost jimf@saber.com code).\"* Its sibling `USERS` (`m_users`, `s_serv_ext.h:44`) lists who's logged into the host.\n- *1990s worldview:* IRC users *are* shell accounts on the very Unix machine running ircd, so \"go find user bob in utmp and echo to his tty\" is a coherent feature.\n- *Why it's dead:* Clients haven't been shell users on the server host for 25+ years; the command is a security hole (host-user enumeration + tty write) that's been compiled off by default, a fossilized assumption that IRC and Unix logins were the same population.\n\n**9. iauth: a whole child process to hide blocking lookups from the event loop.**\n`iauth/iauth.c` is a separate program the ircd talks to over a pipe (`adfd`, `s_auth.c:590` `sendto_iauth(abuf)`), whose entire reason to exist is that the single `select()` loop cannot afford to block on the slow, hostile checks it performs. Its modules are a museum of 1990s abuse vectors: `mod_socks.c` and `mod_webproxy.c` *connect back to the joining client* to probe for open proxies — `fd = tcp_connect(cldata[cl].ourip, cldata[cl].itsip, SOCKSPORT, ...)` (`mod_socks.c:60`), caching results as `0 = no proxy, 1 = open proxy` (`:41`); `mod_rfc931.c` re-implements ident; `mod_dnsbl.c` does DNS blocklist lookups.\n- *1990s worldview:* Blocking work must be exiled to a helper process because threads aren't an option, and the main abuse to defend against is misconfigured open SOCKS relays.\n- *Why it's dead:* Async runtimes make the \"fork a child to avoid blocking\" architecture obsolete, and actively port-scanning every connecting client for open proxies would today read as hostile behavior, not due diligence.\n\n**10. Access control trusts reverse-DNS hostnames, and K-lines ban by hostname.**\n`s_bsd.c:2912` `check_init()` resolves the server's own name via `gethostbyname()` (`:2923`), and throughout, client access (I-lines/K-lines) is matched against the *resolved hostname* returned by the client's PTR record. K-line comments/reasons are stored in `aconf-&gt;passwd` and matched by `match(tmp-&gt;passwd, ...)` glob on hostname (`s_conf.c:2242`). The comment at `s_bsd.c:2910` — *\"If hostname gives another name than cname, then check if there is a CNAME record ... accept cname as our name. meLazy\"* — captures the casual trust in whatever DNS says.\n- *1990s worldview:* A hostname is a stable, honest identifier assigned by a trustworthy admin, so glob-matching on `*.mit.edu` is a meaningful access rule.\n- *Why it's dead:* Reverse DNS is attacker-controllable and near-meaningless behind CGNAT/cloud PTR records; identity-by-hostname was replaced by SASL, accounts, and cryptographic auth because DNS trust is forgeable.\n\n**11. IPv6 was retrofitted as `#ifdef` scar tissue over an IPv4 skeleton.**\nThe v4-vs-v6 seams are everywhere: 54 `INET6`/`s6_addr`/`IN_ADDR` hits in `s_bsd.c` alone, 48 in `res.c`, plus `s_auth.c` and `s_conf.c`. Fossils include `static char hostbuf[HOSTLEN+1+100]; /* +100 for INET6 */` (`res.c:33`) — literally padding a buffer by a magic 100 bytes to fit v6 — and the union-y `struct IN_ADDR` typedef papered over `struct in6_addr` with `bcopy(minus_one, ...s6_addr, IN6ADDRSZ)` sentinels (`s_bsd.c:2900`) and dual `getipnodebyname()`/`gethostbyname()` code paths gated on `HAVE_GETIPNODEBYNAME` (`s_bsd.c:2917-2924`).\n- *1990s worldview:* The address is a 32-bit `struct in_addr`; IPv6 is an afterthought bolted on with conditional compilation rather than a first-class type.\n- *Why it's dead:* Modern code uses address-family-agnostic `sockaddr_storage`/`getaddrinfo` from the start; you don't discover your address type with a forest of `#ifdef INET6` and hand-pad buffers \"+100 for INET6.\"\n\n**12. Portability `#ifdef`s for machines that no longer exist.**\n`s_bsd.c:26` — *\"Added setdtablesize() for more socket connections (sequent OS Dynix only) -- maybe select()-call must be changed ...\"* (dated *Jun 18 1990*), with live code at `s_bsd.c:728` still gated `#ifdef sequent` / `#ifndef DYNIXPTX` calling `setdtablesize(MAXCONNECTIONS + 1)`.

Every finding is quoted verbatim with a `file:line` citation.\n\n---\n\n### 1. Passwords are stored and compared in *plaintext by default*\n`support/config.h.dist:311` and `:319`\n```c\n#undef\tCRYPT_OPER_PASSWORD\n#undef\tCRYPT_LINK_PASSWORD\n```\nThe two toggles that would hash oper and server-link passwords are both `#undef` out of the box. When off, the code path is literally `encr = password;` (`s_user.c:2901`) and `encr = cptr-&gt;passwd;` (`s_serv.c:956`), then `StrEq(encr, aconf-&gt;passwd)`.\n- **Era assumption:** the config file and the wire are trusted; a password sitting in cleartext in `ircd.conf` and traveling in a `PASS` line is fine because only trusted admins can read either.\n- **Modern failure:** any config leak, backup, or packet capture yields every operator and server credential directly; there is no salting, no constant-time compare, no defense-in-depth.\n\n### 2. Even \"crypted\" passwords are DES `crypt(3)`\n`ircd/s_user.c:2888` / `ircd/s_serv.c:936`\n```c\nextern\tchar *crypt();\nencr = crypt(password, aconf-&gt;passwd); /* \"pass whole aconf-&gt;passwd as salt\" */\n```\nThe opt-in \"secure\" mode calls the libc `crypt()` — on the era's systems, DES with a 2-character salt and an 8-character-significant key. The example config even ships a live DES hash: `O|rocker@csa.bu.edu|T0eiVgHrqeKTQ|Rocker||10||` (`doc/ircd.conf.example:180`). `contrib/mkpasswd/mkpasswd.c:22` confirms `FLAG_DES` as a first-class mode.\n- **Era assumption:** DES crypt is \"the\" password primitive; 8 characters and 4096 salts is plenty.\n- **Modern failure:** a 13-char DES hash is brute-forceable in seconds on modern hardware; the 8-char truncation silently discards the tail of any longer password.\n\n### 3. The single-letter, field-position config format\n`ircd/s_conf.c:1587` (`switch (*tmp)`) driving positional reads at `:1681–1730`\n```c\nswitch (*tmp) {\n case 'O': aconf-&gt;status = CONF_OPERATOR; ...\n case 'K': aconf-&gt;status = CONF_KILL; ...\n```\nThe first character of a `|`-delimited line selects the record type (`M/A/P/Y/I/O/C/N/K/L/H/D/V/B/S/Q/…`); every subsequent field is then read purely by ordinal position — `host`, `passwd`, `name`, `port`, `class` — via repeated `getfield(NULL)` calls with the *same code* regardless of line type. The delimiter itself is a compile-time constant: `#define IRCDCONF_DELIMITER '|'` (`config.h.dist:500`).\n- **Era assumption:** configuration is a terse, human-hand-edited flat file for an expert admin who has memorized the field order; the example even warns the file \"is read UPSIDE-DOWN!\" (`ircd.conf.example:47`).\n- **Modern failure:** meaning is entirely positional, so a shifted `|` silently repurposes a field; no schema, no key names, no validation beyond \"did I run out of fields.\"\n\n### 4. `getfield` is a stateful global iterator over one `static` pointer\n`common/parse.c:819`\n```c\nchar\t*getfield(char *irc_newline)\n{\n\tstatic\tchar *line = NULL;\n```\nThe config tokenizer keeps its cursor in a function-local `static` — the parser is a non-reentrant global-state machine walking one line at a time.\n- **Era assumption:** single-threaded daemon, one config parse at a time, no concurrency to worry about ever.\n- **Modern failure:** unshareable, untestable in isolation, and a landmine for any attempt to parse two sources concurrently.\n\n### 5. User bans (K-lines) live in the config file — and `KLINE` appends to it on disk\n`ircd/s_conf.c:2817`\n```c\nkfd = open(KLINE_PATH, O_WRONLY|O_APPEND|O_NDELAY);\n...\nksize = snprintf(kbuf, sizeof(kbuf), \"%c%c%s%c%s%c%s%c0%c #%s...\", 'K', IRCDCONF_DELIMITER, host, ...);\nkret = write(kfd, kbuf, ksize);\n```\nA runtime `/KLINE` command formats a `K|host|reason|user|...` line and appends it to a flat file at a fixed path. Note the hand-rolled injection defense right above it (`:2807–2814`): it scans the user/host/reason for a literal `|` and bails with *\"Too lazy to copy it here. --B.\"* (`:2812`) — because a `|` in a ban reason would inject extra config fields.\n- **Era assumption:** the ban list *is* config; there is no database, so operational state is edited by appending text lines, and the delimiter can never appear in user data.\n- **Modern failure:** config-as-database with string concatenation is textbook injection surface; a single missed delimiter check turns a ban reason into an arbitrary O-line. Bans are also per-server only (\"K-lines are *not* global,\" `ircd.conf.example:311`).\n\n### 6. The command-dispatch table doubles as the metrics store\n`common/parse.c:37` (`struct Message msgtab[]`), incremented in-place at `:692`\n```c\nhandler-&gt;count++;\nhandler-&gt;bytes += i;\n...\nhandler-&gt;rcount++; handler-&gt;rbytes += i;\n```\nand read straight back out by `STATS m` at `ircd/s_serv.c:2049`:\n```c\nif (_mh(0).count + _mh(1).count + ... &gt; 0)\n sendto_one(cptr, replies[RPL_STATSCOMMANDS], ..., _mh(0).count, _mh(0).bytes, ...);\n```\nThe mutable global routing table (command name → per-connection-state handler) carries its own hit counters, so the dispatcher and the metrics subsystem are the same array of structs.\n- **Era assumption:** one global mutable table is the whole program's source of truth; observability is just \"read the counters that happen to hang off the dispatch entries.\"\n- **Modern failure:** metrics and control-flow are fused with no separation of concerns; the table is process-global mutable state with no locking, and you cannot reason about routing without also reasoning about statistics.\n\n### 7. The entire server is a global `aClient` named `me`\n`ircd/ircd.c:31`\n```c\naClient me;\t\t\t/* That's me */\naClient *client = &amp;me;\t\t/* Pointer to beginning of Client list */\n```\nplus a cached wall-clock global `timeofday` re-`time(NULL)`'d all over `io_loop` (`ircd.c:996,1007,1142,…`). The server represents itself as a client struct in a global, and reads \"now\" from a global cache updated by hand each loop iteration.\n- **Era assumption:** there is exactly one server instance per process forever; global singletons and a cached clock are simpler and faster than passing context.\n- **Modern failure:** untestable without booting the whole daemon, impossible to run two instances in-process, and every function silently depends on ambient global state (`ME`, `me.serv-&gt;sid`, `timeofday`).\n\n### 8. Rehash is a signal handler flipping a `volatile` flag\n`ircd/ircd.c:53` + handler at `:120`\n```c\nvolatile static int dorehash = 0, ...\nstatic RETSIGTYPE s_rehash(int s) {\n\t...\n\tif (dorehash &gt;= 1) dorehash = 2; else dorehash = 1;\n}\n```\nThe blessed way to reload config is `kill -HUP` — the example config even recommends it as the *substitute for having an operator online*: *\"the irc administrator can use 'kill -HUP' on the ircd to reload the configuration file\"* (`ircd.conf.example:245`).\n- **Era assumption:** the admin has a shell on the same box as the daemon; Unix signals are the control plane; whoever can send SIGHUP is authorized.\n- **Modern failure:** no authenticated admin API, no audit trail, no atomic/validated reload — config management means \"the person with a login re-reads a flat file,\" and any process that can signal the daemon can force a reload.\n\n### 9. Information-disclosure is a compile-time text toggle, and STATS leaks by design\n`support/config.h.dist:481`\n```c\n/* #define TXT_NOSTATSK \"Please use http://example.org/klines instead\" */\n```\ngating `ircd/s_serv.c:2033` (`if (!IsAnOper(sptr))` → refuse `STATS K`). More telling is `ircd/s_conf.c:1760`:\n```c\n/*\n * On K/V lines the passwd contents can be\n * displayed on STATS reply. \t-Vesa\n */\n```\nThe ban-line \"password\" field (really the reason/comment) is shown to *anyone*; hiding real O/C/N passwords behind `\"*\"` was a later retrofit (`s_serv.c:1787,1795`), and non-opers see the ban list unless you recompile with `TXT_NOSTATSK`. The default comment even shrugs: *\"Note that operators will get list of K anyway\"* (`config.h.dist:479`).\n- **Era assumption:** the network topology, ban list, and config layout are not secrets — transparency among a small operator community is the norm; hiding anything is the exception you compile in.\n- **Modern failure:** default-open information disclosure hands reconnaissance (server links, ban patterns, oper hostmasks) to any connecting client, and policy changes require a rebuild-and-restart.\n\n### 10. An operator privilege literally named \"allows flooding\"\n`doc/INSTALL.txt:903`\n```\n +o p - allows flooding\n +o P - removes penalty\n```\nThe O-line flag set includes bits whose entire purpose is to exempt a user from the anti-flood rate limiter (`config.h.dist:128–139` defines `OPER_*`; flag `A` = \"enables all\"). The example config warns *\"Warning: if you add no flags, no privileges will be granted\"* (`ircd.conf.example:275`).\n- **Era assumption:** operators are trusted staff; the flood protections exist to stop *abusive clients*, and a real oper legitimately needs to bypass them, so \"let this human flood\" is a normal grant.\n- **Modern failure:** a single compromised or rogue oper account gets a switch that disables the exact protection meant to contain abuse — privileged bypass with no rate ceiling and no second factor.\n\n### 11. Remote-kill enabled by default, with a comment admitting it's a mistake\n`support/config.h.dist:137`\n```c\n/* In a perfect world these two (or at least second) would be undefined. */\n#define\tOPER_KILL\n#define\tOPER_KILL_REMOTE\n```\nThe maintainers ship remote-KILL on while documenting that they know it shouldn't be. The config-side counterpart lets peers *refuse* servers that enabled it: `V|IRC/021002*|K|*.edu||` bans links \"compiled with remote oper kills enabled\" (`ircd.conf.example:497`).\n- **Era assumption:** every operator on every peered server is trustworthy staff, so letting any of them kill any user anywhere on the net is acceptable convenience.\n- **Modern failure:** transitive trust across an entire federation means one rogue oper on any linked server can disconnect any user globally; the \"perfect world\" comment is a fossil of known-but-shipped risk.\n\n### 12. `-f` config override is a documented SUID footgun; debug mode dumps passwords\n`support/config.h.dist:210`\n```c\n * NOTE: defining CMDLINE_CONFIG and installing ircd SUID or SGID is a MAJOR\n * security problem - they can use the \"-f\" option to read any files\n * that the 'new' access lets them.\n```\nAnd when debugging is on, every parsed line — including `aconf-&gt;passwd` — is written cleartext to the debug log (`ircd/s_conf.c:2026`):\n```c\nDebug((DEBUG_NOTICE, \"Read Init: (%d) (%s) (%s) (%s) (%d) (%d)\",\n aconf-&gt;status, aconf-&gt;host, aconf-&gt;passwd, aconf-&gt;name, ...));\n```\n- **Era assumption:** the operator runs the daemon by hand from a trusted shell; command-line flags and debug logs are for the admin's eyes only, so echoing secrets is harmless.\n- **Modern failure:** SUID + attacker-controlled `-f` is arbitrary file disclosure via the daemon's privileges, and a debug build silently spills every server-link and oper password into a logfile.\n\n---\n\n**Honorable mention — the \"twilight zone\" security check** (`ircd/s_bsd.c:2803`): the SUMMON/tty path guards a bug with `\"FATAL: major security hack. Notify Administrator !\"` and a jokey user-facing *\"Looks like mere mortal souls are trying to enter the twilight zone...\"* — a fossil of an era when a security violation was a chummy note to the admin, not an incident.

four Opus readers are done. Here's the merged summary — 48 findings distilled to the ones that carry the argument, all verified with file:line citations in `var/ircd`.\n\nOne framing note first: the debt isn't really \"predates the internet\" — it's three distinct extinctions the code survived: **pre-POSIX Unix** (a dozen incompatible vendor Unixes), **pre-cheap-RAM** (every byte a line item), and **pre-hostile-network** (everyone on the wire is presumed staff). Each layer of debt is a fossil of a world that ended.\n\n## The pre-POSIX layer: portability as sediment\n\n* **It ships a 300-line hand-optimized `memcmp`** because `configure` compiles and *runs* a test program to see if your libc's memcmp treats bytes as signed (`support/configure.in:599`). If \"broken,\" `os.h:335` swaps in a word-at-a-time, endianness-aware reimplementation (`support.c:890–1125`) with the comment `/* BE VERY CAREFUL IF YOU CHANGE THIS CODE! */`. ANSI C89 fixed this before most working engineers were born.\n* **Undocumented Solaris internals as a resolver fix**: `#define gethostbyname __switch_gethostbyname` (`os.h:485–506`) — calling a private Sun symbol to dodge a bug in Solaris 2.0–2.2, three point releases of an OS from 1992, from a company that no longer exists.\n* **The `accept()` third-argument guessing game**: configure brute-forces `int`/`size_t`/`socklen_t`/`unsigned int` (`configure.in:23`) because the type legitimately changed three times during the Unix wars; `os.h:566–580` contains a resigned essay about X/Open SPEC 1170.\n* **A tokenizer that parses ISO-2022-JP escape sequences** so it won't split a Japanese nickname on a comma byte that's actually mid-glyph (`support.c:78–90`) — a stateful parser for a text encoding UTF-8 made extinct.\n* **Embalmed metadata**: the FSF's pre-2005 street address in 74 files, and CVS `$Id$` strings kept alive by `volatile` so `what(1)` could scrape them — frozen forever because git doesn't expand keywords.\n\n## The pre-cheap-RAM layer: every byte a line item\n\n* **The partial-struct allocation trick** — the crown jewel. Remote clients are `malloc`'d only up to `offsetof(aClient, count)` (`struct_def.h:577`, `list.c:92`); the local-only tail (512-byte input buffer, queues, password) simply doesn't exist for them. The invariant is enforced by a comment: `*Never* refer to these fields, if (from != self)`. Megabytes saved on a 5,000-user hub; undefined behavior one field-access away, forever.\n* **The output path is `vsprintf` into a shared global `char sendbuf[2048]`, length-checked *after* the write** (`send.c:367`: `len = vsprintf(...); if (len > 510) len = 510;`). The overflow check is cosmetic — the smash already happened. This single pattern is the memory-safety argument for the whole rewrite.\n* **A homemade allocator with a `\"VAVA\"` canary**: `MyMalloc` stashes pointer+size+magic trailer and `MyFree` calls `dumpcore()` on mismatch (`support.c:557,637`), plus a global 100,000-entry shadow table of live pointers — valgrind, hand-knitted, because it didn't exist yet.\n* **The buffer-pool block is hand-sized to a 2KB page assuming 4-byte pointers**: `char data[2032]` with avalon's comment explaining he left \"a bit for malloc to play with\" (`dbuf_def.h:64`). Silently wrong on every 64-bit machine it's run on since.\n* **A refcount that moonlights as a state machine**: `free_user` poisons the count with `-211000` to detect double-free loops, checks for `-211001`, and carries `/* XXX: Remove loop detection before 2.11.0 - jv */` (`list.c:251–297`). It shipped.\n* **`#define BUFSIZE 512 /* WARNING: *DONT* CHANGE THIS!!!! */`** (`struct_def.h:57`) — the constant screams because it's not a tunable, it's an assumption duplicated across hundreds of stack buffers. (This is your 2048-grapheme heresy's origin story.)\n\n## The pre-hostile-network layer: everyone on the wire is staff\n\n* **Authentication is asking the attacker's machine who they are**: ident/RFC 1413 — the server connects back to the client's port 113 and whatever string comes back *becomes the username* (`s_auth.c:528–795`). Coherent when every client was a shell account on a university machine with a sysadmin-run identd; a textbook anti-pattern now.\n* **SUMMON**: the server scans the host's utmp and writes directly to a logged-in user's tty to page them into IRC (`s_serv.c:1489–1552`, code dated \"10/9/90\"). From when IRC users and Unix logins on the server box were the same population. Bonus: the tty path's error message is `\"Looks like mere mortal souls are trying to enter the twilight zone...\"` (`s_bsd.c:2803`).\n* **It vendors the 1985 Berkeley BIND resolver** (`res_mkquery.c`, \"Copyright 1985, 1993 Regents of the University of California\") — a chat server hand-driving raw DNS-over-UDP packets because `gethostbyname()` blocks and threads weren't an option. The iauth child process exists for the same reason, and its modules **port-scan every connecting client for open SOCKS proxies** (`mod_socks.c:60`) — 1990s due diligence, 2020s hostile behavior.\n* **Server links are a plaintext `strcmp`** (`s_conf.c:575`), upgraded at best to 1970s DES `crypt()` behind an `#ifdef` that ships **off** (`config.h.dist:311`). No TLS anywhere — \"TLS support\" is a port flag meaning \"trust the IP an external stunnel hands us\" (`s_auth.c:582`).\n* **`#define MAXCONNECTIONS 50`** (`config.h.dist:150`) — the shipped default. Capacity is a compile-time constant that sizes the fd array, both hash tables, and the whowas buffer. Want more users? Recompile.\n\n## The pre-adversarial-operations layer: config is the database, trust is ambient\n\n* **Remote KILL ships enabled with a confession**: `/* In a perfect world these two (or at least second) would be undefined. */ #define OPER_KILL_REMOTE` (`config.h.dist:137`) — known-but-shipped transitive trust across the whole federation, and the config format even has a `V:` line for *refusing to link* with servers compiled this way.\n* **`/KLINE` is string-concatenation into the config file** (`s_conf.c:2817`), guarded by a hand-rolled injection check for the `|` delimiter whose comment reads `\"Too lazy to copy it here. --B.\"` A ban reason containing the delimiter would otherwise become arbitrary config lines.\n* **An oper privilege named \"allows flooding\"** (`doc/INSTALL.txt:903`: `+o p - allows flooding`) — a grantable bit whose purpose is disabling the abuse protection. (This is the pair of dead privileges your flood-penalty slice found still parsed-but-unread in the Rust port — nice cross-reference for the post.)\n* **The dispatch table is the metrics store**: `msgtab[]` entries mutate `count`/`bytes` on every dispatch and `STATS m` reads them back (`parse.c:692`, `s_serv.c:2049`) — routing and observability fused into one global mutable array. And the server itself is `aClient me; /* That's me */` (`ircd.c:31`), which is precisely why the Rust tests needed mutexes around \"the entire server as a global variable.\"\n\n## For the blog post\n\nThe strongest single section is the **pre-cheap-RAM** material, because it's the causal spine of your whole experiment: `CLIENT_REMOTE_SIZE`, the self-pointers, and the `vsprintf`-then-check pattern aren't just funny fossils — they're the *specific* reasons the faithful port needed raw pointers and byte-diffing, and the specific things `leveva` got to delete. The fossils with a payoff later in your story beat the merely absurd ones.\n\nFor pure color, the five best pull-quotes: the `\"VAVA\"` canary, `*Never* refer to these fields, if (from != self)`, the `-211000` refcount sentinel, \"In a perfect world these two would be undefined,\" and SUMMON's twilight-zone message. And the tightest one-sentence summary of the whole codebase: *configuration is the database, the dispatch table is the metrics system, the server is a global variable named `me`, and everyone on the wire is presumed to be staff.*\n\nFull agent reports have more per-item detail (byte-savings math, era context per finding) — say the word if you want them stitched into a single reference doc in the repo."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":131,"cache_creation_input_tokens":5180,"cache_read_input_tokens":129809,"output_tokens":3571,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":5180,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":131,"output_tokens":3571,"cache_read_input_tokens":129809,"cache_creation_input_tokens":5180,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5180},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Ccjh6mrRNBgcZAyRgkv8e","type":"assistant","uuid":"030e65d1-ca4f-4a04-a4b4-b3934f733aa1","timestamp":"2026-07-05T22:23:46.545Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 240 240 + {"parentUuid":"030e65d1-ca4f-4a04-a4b4-b3934f733aa1","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"f1dd3902-1efe-4a6e-9de0-3bfd187a5646","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":73},"type":"attachment","uuid":"8d2666eb-7e17-416d-9c49-c0f570a3e06f","timestamp":"2026-07-05T22:23:46.646Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 241 241 + {"parentUuid":"8d2666eb-7e17-416d-9c49-c0f570a3e06f","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":73},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":28}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-05T22:23:46.647Z","uuid":"a12b1af5-33d0-4053-af00-e438c47ff25a","toolUseID":"f1dd3902-1efe-4a6e-9de0-3bfd187a5646","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 242 242 + {"parentUuid":"a12b1af5-33d0-4053-af00-e438c47ff25a","isSidechain":false,"type":"system","subtype":"away_summary","content":"You're gathering material for your blog post about the ircd Rust vibecoding experiment.

— the agent was right, and it's even better than the summary made it sound. Three facts from the tree:\n\n1. **There is no crypto in the daemon at all.** Zero hits for `SSL_new`/`SSL_accept`/`SSL_read`/`ssl.h`/`libssl` anywhere in `ircd/`, `common/`, or `iauth/`, and the configure scripts never probe for OpenSSL. The program is incapable of decrypting a byte.\n\n2. **The `T` port flag is purely declarative.** `pline_flags_parse` in `ircd/s_conf.c:200` sets `PFLAG_TLS`, and the maintainer's own comment says the quiet part out loud:\n\n ```c\n /*\n * This only marks the port as secure, you must ensure that it actually is -- mh 2020-04-27\n */\n ```\n\n Note the date: **2020**. This isn't just a 1990s fossil — the codebase was still being maintained into this decade, and the answer to TLS was still \"put a letter in the config that asserts the port is secure, and make it true yourself somehow.\"\n\n3. **What the flag actually does** is cosmetic-plus-one-workaround: clients on a `T` port get `SetTLS`, which produces the \"your connection is secure\" notice at registration (`s_user.c:771`) and the WHOIS secure-connection line (`s_user.c:2179`). The one functional bit is in `s_auth.c:583` — since the TCP peer on a proxied port is stunnel, not the user, the ident callback would bind to the wrong address, so the P-line grows a `source_ip` field telling the daemon which IP to pretend the connection arrived on. The daemon literally trusts a config field over the socket's actual peer address.\n\nSo the deployment model is exactly what you said: stunnel (or haproxy) terminates TLS and forwards plaintext to a port whose \"security\" is an operator promise. If the operator lies — or someone connects to the plaintext port stunnel forwards to, which is sitting right there on localhost — every client on it still gets told \"this connection is secure.\"\n\nFor the blog post, the 2020 comment is the kicker. The natural contrast sentence writes itself: the C daemon's TLS story in 2020 was an honor-system config flag; leveva runs rustls natively on client ports *and* both directions of server links."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1212,"cache_read_input_tokens":139317,"output_tokens":1258,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1212,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":1258,"cache_read_input_tokens":139317,"cache_creation_input_tokens":1212,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1212},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjkcvTnCowEBmLNBjj1t","type":"assistant","uuid":"e997aab0-5213-461b-ae63-c96cfce67f54","timestamp":"2026-07-05T23:09:22.836Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 255 255 + {"type":"last-prompt","lastPrompt":"wait does it really not support listening over TLS? it just relies on stunnel sending it decrypted sockets?","leafUuid":"e997aab0-5213-461b-ae63-c96cfce67f54","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 256 256 + {"type":"ai-title","aiTitle":"IRC daemon vibecoding experiment outline","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 257 257 + {"type":"mode","mode":"normal","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69"} 258 258 + {"parentUuid":"e997aab0-5213-461b-ae63-c96cfce67f54","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"342dd439-29e2-42d5-931b-b5e57495ae8b","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":71},"type":"attachment","uuid":"9efc2579-62f2-4a8b-8a15-5b5f9189a122","timestamp":"2026-07-05T23:09:22.938Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 259 259 + {"parentUuid":"9efc2579-62f2-4a8b-8a15-5b5f9189a122","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":71},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":21}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-05T23:09:22.939Z","uuid":"78956f3c-30f8-4e69-a82c-71980c21ce67","toolUseID":"342dd439-29e2-42d5-931b-b5e57495ae8b","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 260 260 + {"parentUuid":"78956f3c-30f8-4e69-a82c-71980c21ce67","isSidechain":false,"type":"system","subtype":"away_summary","content":"You're gathering material for your blog post about the ircd Rust vibecoding experiment; four Opus agents mined the C tree for pre-internet technical debt and I merged their findings.

Can you look it over and give me advice on what to change or drop?\n\n# My vibecoding experiment of an IRC daemon in Rust\n\nOutline:\n\n* Early June I decided to see how effectively Claude Opus could port an IRC daemon to Rust, then use that Rust version of the program as a correctness oracle to write a new IRC daemon in idiomatic Rust. \n * Software rewrites in other languages fail. This is a known fact. Any time someone tells you that they're doing a big rewrite in Rust, they're going to fail. It is a matter of when, not if. \n * As codebases get bigger, more legacy behaviour and workarounds get ossified into place. This behaviour is lost in rewrites and ends up making integration with third parties difficult or impossible. \n * The only exception to this is when you do a [Strangler Fig migration](https://martinfowler.com/bliki/StranglerFigApplication.html). This is when you start to modernize a codebase by gradually replacing codepaths with a new version of the same functionality. \n * I ended up wondering if existing off the shelf tools could be good enough to help rewrite a program in Rust by building detailed context about a C codebase by mechanically translating it to Rust and then using that to do a full greenfield rewrite. \n * This started out as an experimental offshoot of my [\"No way to prevent this\" say users of only language where this regularly happens](https://xeiaso.net/shitposts/no-way-to-prevent-this/memory-safety/CVE-2026-8461/) blogposts where I've been wondering if existing tools off the shelf are good enough to start moving our existing C code to Rust \n* The project I chose: ircnet/ircd \n * Why IRC? \n * IRC is a very simple protocol with an innumerable number of edge cases. \n * I have a long history of maintaining IRC server software. \n * This combination gives me a unique insight into how this protocol works and fails in practice. I'm kind of out of practice as I [stopped working on an IRCd in 2019](https://xeiaso.net/blog/deprecation-notice-elemental-ircd-2019-02-11/). \n * The exact IRC daemon I maintained was [way deep down the IRCd family tree](https://github.com/grawity/irc-docs/blob/d6941670a9013cfe81f0493ef1ddf28cfe6585b9/family-tree.txt#L69). I didn't want to pick it because it's based on [ircd-ratbox](https://ratbox.org/), which has a lot of complicated multi-platform support features that are frankly irrelevant in modern setups. \n * I wanted to pick an IRC daemon that was just complicated enough to exercise a lot of the issues you'd see in the real world, but not so complicated that the forest would be lost for the trees. \n* Ground rules \n * When I set out to do this, I set a few ground rules: \n * The existing C code is a [correctness oracle](https://en.wikipedia.org/wiki/Test_oracle), all changes will be compared against the correctness oracle to ensure that they are accurate. \n * I wanted to do as little action as possible and leave this running on a side monitor. \n * Eventually I had to move this from my tower to another machine because claude running tests could cause my tower to OOM, crashing my games \n * When converting the C to Rust, do the migration both outside-in and inside-out. \n * The main() function became Rust as early as possible, it mostly converted arguments/envvars/flags to the right things in C and kicked off the C code \n * When doing the greenfield rewrite, use the Rust version of the IRC daemon as a line protocol correctness oracle \n * The oracle does not have to be pretty, it just has to work enough to help ensure tests pass \n * Leaving the IRCNet team alone \n * They don't know I'm doing this experiment. I don't want them to have to care that I have done this experiment. Leave them alone. They have enough to work on already. \n* The state of the codebase \n * Look, I'm not here to shit-talk the ircnet team for what they're building/have built. They have to exist under unimaginable amounts of technical debt. \n * I'm also not about to say that this codebase is a paragon of technical excellence either. This is a codebase that is older than I am and in some places it really shows. \n * The configuration file format is completely handrolled. Way back in the before times the configuration file used the `:` character for separating arguments, EG: (embed sample config file) \n * This ended up having a lot of problems when IPv6 deployment became more common, as IPv6 addresses use colons in them. \n * [https://github.com/ircnet/ircd/pull/9\\#issuecomment-2496425611](https://github.com/ircnet/ircd/pull/9#issuecomment-2496425611) \n * IRC line output is a buffer overflow waiting to happen \n * The output path of IRC messages is a shared global 2048 character buffer that is length-checked *after* any writes are made. This single pattern is so egregious that it's a peak example of why we need to start abandoning C as an industry. \n * This codebase predates POSIX, which standardized behaviour across dozens of mutually incompatible UNIX environments \n * This is generally why it uses the autoconf behaviour of generating and compiling portability oracles, this is how it knows which set of compatibility hacks it needs to enable at compile time. \n * This includes but is not limited to a hand-optimized version of `memcmp` (memory compare) that is only used if your system's C library treats bytes as *signed*. \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/support/configure.in\\#L599-L611](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/support/configure.in#L599-L611) \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/support.c\\#L1125](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/support.c#L1125) \n * I'm certain that the ANSI C standard fixed this before most people currently working in the tech industry were born \n * Apparently Solaris releases in 1992 had a bug involved with `gethostbyname` (the main DNS lookup function). To this day ircnet/ircd ships a compatibility hack that uses the undocumented internal implementation of a fixed version. \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/os.h\\#L485-L493](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/os.h#L485-L493) \n * One of the core operations on sockets is accepting connections. During the Unix wars, the type of the third arguments of `accept()` legitimately changed three times before the current winner became accepted. The source code contains a small essay about a Unix standard I wasn't aware existed. \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/os.h\\#L566-L580](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/os.h#L566-L580) \n * Ircd has load-bearing dependencies on a technique called partial allocation \n * A pithy way to describe how C works is that in C, types don't exist. All that really exists is machine words. This is true for integers, boolean values, floating-point numbers, and data structures. \n * Copy things from here: [https://claude.ai/chat/6e35150e-110d-4e18-8961-c81efc7e25a2](https://claude.ai/chat/6e35150e-110d-4e18-8961-c81efc7e25a2) \n * At a low level, when you are allocating memory for a structure such as information about IRC clients there is no reason that you need to allocate *the entire struct* at once. \n * Maybe every client struct has details that aren't relevant all of the time, such as a local send queue / receive queue. You wouldn't need to care about those for *remote* clients, right? \n * The downside is that when you do this, you *need* to be careful to *never* reference those fields when they are in a context where they aren't allocated, otherwise you are walking outside of the struct into random memory. \n * This is a classic example of an out of bounds read which can lead to security issues. \n * Something something safety level: landmines afoot \n * Why would you want to do this? In 1988 there was a sudden DRAM shortage that made a 256 kilobyte ram chip that normally sold for about $3 cost $9. Higher capacity chips that normally sold for $43 per megabyte of actually cost $300 per megabyte. \n * I wonder what current parts shortage sounds familiar. \n * [https://www.vice.com/en/article/the-year-that-the-entire-computer-industry-ran-out-of-memory/](https://www.vice.com/en/article/the-year-that-the-entire-computer-industry-ran-out-of-memory/) \n * RAM was really expensive, so any hack you could perform to save *bytes* of memory would add up to huge cost savings on computer hardware. \n * Ircd vendors a copy of the 1985 Berkely BIND resolver so that it can rawdog DNS packets over the wire. The reason you'd want to do this is that ircd is a *very* single-threaded program, so if `gethostbyname` blocked the only thread, the entire chat server would block and that could lead to problems for clients trying to send data to the server. \n * TLS is external to the IRC daemon \n * Back when I maintained elemental-ircd, it would spawn a number of ssld subprocesses that handled taking TLS sockets and outsourced the encryption/decryption. \n * Again, you want to do this because at the time it was implemented, TLS encryption/decryption was time-consuming and \"slow\" across the scale of IRC network deployments. Outsourcing this to a subprocess made the IRC daemon more snappy. \n * With ircnet/ircd, all SSL termination and implementation was expected to be done outside of the IRC daemon via utilities like [stunnel](https://www.stunnel.org/). \n * All global state is globally mutable \n * Again, this is not as big of a problem in a single-threaded environment like ircd, but it means that any \"multithreaded\" features have to become subprocesses instead of async tasks or

is in good shape — the personal history and the era-context framing (DRAM crisis, Unix wars) are doing exactly what I hoped. Here's what I'd fix, tightened to accuracy issues first, then structure.\n\n## Accuracy fixes (worth getting right before someone on the orange site does)\n\n* **\"This codebase predates POSIX\"** — shaky as stated. POSIX.1 is 1988; this lineage starts 1989–90. What's true and stronger: it predates POSIX being something you could *rely on*. The build system exists because POSIX was on paper but the installed base was a dozen incompatible vendor Unixes. Reword rather than drop.\n* **accept() \"changed three times\"** — it went `int` → `size_t` (X/Open SPEC 1170) → `socklen_t` (POSIX): three types, *two* changes. Say \"went through three different types\" and you're safe. Also, the \"standard I wasn't aware existed\" is X/Open SPEC 1170 / Single UNIX Specification — worth naming since that's the fun fact.\n* **Solaris workaround wording** — \"undocumented internal implementation of a fixed version\" isn't quite it. The libc `gethostbyname` was broken (always returned null aliases); the workaround `#define`s it to `__switch_gethostbyname`, a *private, undocumented* Sun-internal function that didn't have the bug. The absurdity is depending on a symbol Sun never promised to keep, for three point releases of an OS from 1992–93.\n* **Partial allocation + the 1988 DRAM crisis** — be careful with causation. The DRAM crisis is great *era* color, but I can't tell you `CLIENT_REMOTE_SIZE` was written *because of* it (that trick smells like early-90s avalon-era work). Frame it as \"this is what RAM cost in the era this code was written\" rather than \"this is why they did it,\" and you're bulletproof. The airtight version of the motivation is in the code itself: a hub relaying thousands of remote users saves the ~600-byte local tail (a 512-byte input buffer, queues, password) per remote client.\n* **Typo:** \"Berkely\" → \"Berkeley.\"\n\n## What to drop or compress\n\n* **The two duplicate \"are off-the-shelf tools good enough\" bullets.** The sub-bullet under strangler fig and the CVE-series bullet say the same sentence twice. Merge them — the CVE-series origin is the better home, since it gives the question a *reason* to exist.\n* **One of the three autoconf fossils.** memcmp / Solaris / accept() in a row reads as a listicle. memcmp is the strongest (keep — and quote `/* BE VERY CAREFUL IF YOU CHANGE THIS CODE! */`, it's the best line). I'd keep Solaris too and cut the accept() essay to a single sentence or fold it into the POSIX bullet as an example. Three full treatments is where a reader starts skimming.\n* **The \"types don't exist, only machine words\" preamble.** You don't need the philosophy lecture to land partial allocation — \"malloc takes a byte count, and nothing stops you from allocating only the front half of a struct\" gets there in one sentence and is more concrete. Save the types-don't-exist riff for if/when you contrast with what Rust forces (the `enum { Local(Box<LocalData>), Remote }` shape, where touching local fields on a remote client is a compile error instead of a comment).\n\n## What to change\n\n* **\"Outside-in and inside-out\" needs one clarifying line** because right now only outside-in is explained. The actual shape: `main()` became Rust on day one (outside-in), the leaf utility modules were ported first (inside-out), and the migration met in the middle — with the linker keeping exactly one definition of every symbol alive the whole time so the program built and booted after every single move. That last clause is the load-bearing one; it's what \"strangler fig\" concretely meant here.\n* **The ground rules bury your best twist.** \"The oracle does not have to be pretty, it just has to work\" is the thesis sentence of the whole post, and it's currently a sub-sub-bullet. Consider the foreshadow line here: *\"What I didn't plan on was doing the strangler fig twice — and the second fig strangling the first.\"* Then the reader carries that through the whole codebase-tour section knowing where this is going.\n* **The config-format bullet is missing its punchline.** The `:` delimiter broke on IPv6 — and the fix was… switching to `|`, another single-character delimiter, positionally parsed, now with a hand-rolled injection check in the `/KLINE` handler (a ban reason containing `|` would otherwise append arbitrary config lines) whose comment reads `\"Too lazy to copy it here. --B.\"` The delimiter changed; the failure class didn't. That's the technical-debt thesis in miniature, and it sets up leveva using a real config language later.\n\n## What to add\n\n* **The TLS section is one detail short of its kicker.** You have the stunnel/ssld history right, but the tree's own text is better than any paraphrase: the `T` port flag's comment is `/* This only marks the port as secure, you must ensure that it actually is -- mh 2020-04-27 */`. Dated **2020**. The daemon's TLS story, this decade, is an honor-system config flag — and clients on that port get told \"your connection is secure\" based on nothing but the operator's promise. Plus the one functional consequence: the P-line grows a `source_ip` field, i.e. the daemon trusts a config value over the socket's actual peer address.\n* **Wire each fossil to its payoff.** Right now the codebase tour is (good) standalone color. It gets stronger if each item is a Chekhov's gun: partial allocation → why the mechanical port had to be raw-pointers-everywhere and what Rust made unexpressible; the `sendbuf` overflow → why the port built a raw-byte `wire!` builder instead of `format!`; globally-mutable state → why the test suite needed mutexes around \"the server is a global variable named `me`\" (and that `aClient me; /* That's me */` is a quote worth stealing). Even just ordering the fossils to match the order they'll pay off later makes the post feel engineered instead of collected.\n* **Tiny one:** \"Early June\" → \"Early June 2026.\" Blog posts outlive their context.\n\nOne last structural observation: \"The state of the codebase\" is already ~60% of this excerpt, and you have the leak-audit, prod-desync, and oracle-was-wrong material still to come. I'd hold the line at the current five-ish fossils and resist adding more — you have enough banked that the temptation will be real, and every one you add dilutes the ones that pay off later."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":3650,"cache_read_input_tokens":141787,"output_tokens":5680,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":3650,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":5680,"cache_read_input_tokens":141787,"cache_creation_input_tokens":3650,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":3650},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjmQ9CkDY8jUGo4z9SLm","type":"assistant","uuid":"9d1de5f0-e12c-4e9f-8eff-0335cce9d546","timestamp":"2026-07-05T23:20:43.445Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 265 265 + {"parentUuid":"9d1de5f0-e12c-4e9f-8eff-0335cce9d546","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"3689981b-08de-4b6c-a401-217f48c510bc","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":52},"type":"attachment","uuid":"101ea950-531e-4ba7-8431-4f5bce387b87","timestamp":"2026-07-05T23:20:43.524Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 266 266 + {"parentUuid":"101ea950-531e-4ba7-8431-4f5bce387b87","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":52},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":17}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-05T23:20:43.524Z","uuid":"479fb41b-d396-409f-a4c8-29ef11a29932","toolUseID":"3689981b-08de-4b6c-a401-217f48c510bc","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 267 267 + {"type":"last-prompt","lastPrompt":"how's this for the first bit?

&lt;5% adoption | No major server implementation |\n| `draft/client-batch` | Minimal; &lt;5% adoption | Rarely implemented |\n| `draft/extended-isupport` | Minimal; &lt;5% adoption | Still evolving; no stable implementation |\n| `draft/network-icon` | Minimal; &lt;5% adoption | Marketing feature; low priority |\n| `draft/oper-tag` | Minimal; &lt;5% adoption | Draft tag; limited client use |\n| `draft/sni` | Minimal; &lt;5% adoption | TLS SNI negotiation; overshadowed by STS |\n| `STARTTLS` | **Deprecated** | Superseded by STS + implicit TLS |\n| `draft/relaymsg` | Defunct/merged | Earlier draft; superseded by other mechanisms |\n\n**Source:** ircv3.net specs page (drafts listed as WIP with no major implementation claims).\n\n---\n\n## **Key Findings for Bouncer-Less Deployment**\n\n**Critical for modern stateless usage:**\n1. **`echo-message`** — Client confirms its own messages (no round-trip via server required)\n2. **`draft/chathistory`** — History replay on join/reconnect without a bouncer (supported by Ergo, UnrealIRCd 6+, IRCCloud)\n3. **`draft/read-marker`** — Sync read position across client instances (IRCCloud only currently; emerging need for multi-device)\n4. **`labeled-response`** — Request-response correlation for async request handling without state\n\nThe absence of `draft/chathistory` on networks like Libera.Chat (Solanum) and older UnrealIRCd is a deployment constraint for bouncer-less clients; this is the single largest gap in production networks.\n\n---\n\n## **Sources Cited**\n- ircv3.net/irc/: Specification listing and descriptions\n- ircv3.net/support/networks: Server/network support matrix (Ergo, InspIRCd, UnrealIRCd, Solanum, Libera.Chat, ergo.chat, Teranova, tilde.chat)\n- ircv3.net/software/clients: Client support matrix (WeeChat, mIRC, Limnoria, HexChat, Irssi, Halloy, IRCCloud, gamja, ObsidianIRC)\n- ircv3.net/software/servers: Detailed server capability inventory</result>\n<usage><subagent_tokens>31641</subagent_tokens><tool_uses>20</tool_uses><duration_ms>85548</duration_ms></usage>\n</task-notification>"},"uuid":"246b606b-3705-4a8e-bfc4-fa7d23823a9b","timestamp":"2026-07-05T23:55:11.098Z","permissionMode":"auto","origin":{"kind":"task-notification"},"promptSource":"system","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 286 286 + {"parentUuid":"246b606b-3705-4a8e-bfc4-fa7d23823a9b","isSidechain":false,"attachment":{"type":"task_reminder","content":[],"itemCount":0},"type":"attachment","uuid":"ea1d4afe-0eaf-46b0-8ab3-f2e887463c7a","timestamp":"2026-07-05T23:55:11.097Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs/var/ircd","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 287 287 + {"type":"last-prompt","lastPrompt":"Can you spawn two haiku agents over the leveva source code? 1.

reports are in, plus my two spot-checks (the audit missed that leveva already advertises `UTF8ONLY` at `isupport.rs:123` and already has a WebSocket transport from slice 53 — worth knowing the Haiku audit had blind spots, so I verified the negative claims that mattered). One caveat on the survey: Haiku's precise percentages (\"97% of servers\") are not to be trusted, but its tier *structure* matches the ircv3.net support tables.\n\n## Synthesis: leveva vs. the ecosystem\n\nThe headline: **leveva is not chasing the ecosystem — it's ahead of it.** Crossing the adoption tiers against the audit:\n\n**Tier 1 (table stakes): complete.** All of it — `message-tags`, `server-time`, `batch`, `labeled-response`, `echo-message`, `sasl` (PLAIN + EXTERNAL), `account-notify`/`account-tag`, `extended-join`, `multi-prefix`, `userhost-in-names`, `away-notify`, `invite-notify`, `chghost`, `setname`, `cap-notify`, `monitor`/`extended-monitor`, `sts`, bot mode, `msgid` (as a tag), WHOX, WEBIRC. Every advertised cap is behavior-wired, none are advertise-only.\n\n**The bouncer-less quartet: complete.** This is the strategically interesting bit. The survey identifies `echo-message` + `draft/chathistory` + `draft/read-marker` + `labeled-response` as what makes multi-device, bouncer-free IRC work — and notes that even Libera.Chat/Solanum lacks chathistory. leveva has all four, with all six CHATHISTORY subcommands plus `draft/event-playback`. Only Ergo and IRCCloud are in this club. That's a docs/blog marketing point, not just a checklist result.\n\n**Ahead of adoption:** leveva ships five drafts with under ~15% ecosystem adoption — `draft/pre-away`, `draft/metadata-2`, `draft/read-marker`, `no-implicit-names`, `draft/oper-tag`, plus `draft/message-redaction`. On these, leveva is among the first implementations, which cuts both ways: differentiation, but also exposure to spec churn (drafts get renamed or breaking-changed before ratification — `metadata` already died once and came back as `metadata-2`).\n\n**Genuine gaps: two.**\n\n## TODO list\n\n**Do:**\n\n1. **`draft/multiline`** — the only Tier-2 spec with real client momentum (Halloy, web clients) that leveva lacks. Prereqs (`batch`, `message-tags`, cap framework) are all in place, so it's a normal-sized slice: a `draft/multiline` batch type accepted from clients, concat/fallback semantics for non-supporting recipients, `max-bytes`/`max-lines` cap values, and S2S relay of the batch (which per your ENCAP rule means deciding how a multiline batch rides to older peers — probably flatten at the boundary).\n2. **`draft/account-registration`** — the self-serve `REGISTER`/`VERIFY` flow. Adoption is modest but it pairs with infrastructure leveva already has: the SASL relay to the `+S` services agent (slice 253/303) is the natural transport, same shape as the existing AUTHENTICATE relay. Worth a design pass first: it's only meaningful if ShadowNET's services agent actually supports registration, so this is gated on the services side, not the daemon.\n\n**Watch, don't build yet:**\n\n3. **Spec-churn audit of the shipped drafts** — a small recurring task, not a feature: check the six `draft/*` caps leveva ships against current ircv3.net text once in a while (rename/ratification of `chathistory` and `message-redaction` are the likeliest movers; ratification means advertising the un-prefixed name alongside the draft name for a transition period).\n\n**Deliberately skip (record as won't-do so future sessions don't treat them as gaps):**\n\n4. `draft/relaymsg` (defunct/superseded), `draft/channel-rename`, `draft/client-batch`, `draft/network-icon`, `draft/sni`, `STARTTLS` (deprecated in favor of STS + native TLS, which leveva already has both of). All dead-tier, and several would fight leveva's design (channel-rename vs. the TS merge machinery, for one).\n\nItem 1 is the only thing I'd call a real gap for a 2026 daemon; item 2 is the only other build-worthy thing on the horizon. Everything else on ircv3.net is either done or correctly dead. Want me to record this as a memory note (so the skip-list binds future sessions the way CLOSE/SET/SERVICE do) or seed a plan file for the multiline slice?"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1913,"cache_read_input_tokens":161092,"output_tokens":2221,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1913,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":2221,"cache_read_input_tokens":161092,"cache_creation_input_tokens":1913,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1913},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjpEwjXooKkWS7sBuHgX","type":"assistant","uuid":"c63b9184-80f1-435c-8b00-d6c3c68bbe96","timestamp":"2026-07-05T23:57:07.305Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 304 304 + {"parentUuid":"c63b9184-80f1-435c-8b00-d6c3c68bbe96","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"1bb37ae1-ba4a-429a-8a3a-9dd2e8a421c3","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":72},"type":"attachment","uuid":"0d6ccc34-5f0b-4762-9391-87ae4616565a","timestamp":"2026-07-05T23:57:07.594Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 305 305 + {"parentUuid":"0d6ccc34-5f0b-4762-9391-87ae4616565a","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":72},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":9}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-05T23:57:07.596Z","uuid":"c61cd23f-643e-4ba2-8e09-9d76a078b5fd","toolUseID":"1bb37ae1-ba4a-429a-8a3a-9dd2e8a421c3","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 306 306 + {"type":"last-prompt","lastPrompt":"Can you spawn two haiku agents over the leveva source code? 1.

— the memory sweeps surfaced several that we haven't talked about yet, and a few of them are arguably better \"agent ran into trouble\" stories than the ones already in your outline. Grouped by failure type:\n\n**The model's training data fighting the actual codebase.** The best one: the agent confused IRC *lineages*. It initially treated IRCnet's server-to-server protocol as if it were the TS6/Undernet family (the lineage most modern daemons — and most of its training data — descend from), and nearly recorded a false \"divergence\" where it claimed the oracle used `SJOIN` semantics it simply doesn't have. IRCnet uses `NJOIN`, a different beast. It got caught by an adversarial design-review pass, not by a test. That's a distinct and underreported agent failure mode: the prior from a thousand ratbox-descended codebases silently overriding the one codebase actually in front of it. Your ratbox history makes this personal — the agent kept trying to write the IRCd *you* used to maintain.\n\n**The test harness fighting back.** A whole genre of problems where the verification machinery itself was the bug:\n\n* The linker kept discarding the Rust library from test binaries: a differential test made only of `extern` declarations references no actual Rust item, so rustc drops the rlib and every C symbol goes undefined. Every test needed a `link_anchor()` call that touches one real Rust item just to keep the crate alive.\n* `static` C functions have no renamed oracle symbol, so they simply *couldn't* be differentially tested — a structural blind spot in the objcopy trick, discovered when a config-parsing function turned out to be static.\n* Parallel test execution raced on the C globals with a vivid symptom: oper-flag strings scrambling under load (`LKSClhdrRDeTqPpt` intermittently rendering as just `t`). The whole point of the port was escaping global mutable state, and the tests had to grow mutexes because the *faithful* port faithfully kept it.\n* The differential harness had its own portability bugs, which is a lovely irony given the C's portability sediment: test buffers typed `i8` only compile on x86_64 (`c_char` is `u8` on aarch64), and one test failed to *link* on the dev box because `irc_memcmp` is compiled out when configure decides your memcmp isn't broken — the 1990s feature-detection maze reached forward in time and broke a 2026 Rust test.\n\n**Self-inflicted time bombs.** Beyond the `'z'` unknown-mode-letter one you know about: the server's `LINK_VERSION` string was embedded in handshake snapshots, so every version bump broke a scatter of \"unrelated\" tests, repeatedly, until it was ritualized (fix as a separate prep commit, `git stash` to prove pre-existing). Same genre as the proptest-model staleness — the agent's tests kept encoding *copies* of facts instead of references to them, and each copy went stale on its own schedule.\n\n**Capacity surprises.** Two small but funny ones: the channel-mode flags bitfield ran out — a `u32` filled up with 32 modes and slice 308 had to widen the whole bitfield family to `u64` (the agent hit the same wall the C authors hit decades ago, just with more type safety). And the agent's own memory index outgrew its size limit — `MEMORY.md` is over its load budget *right now*, this session got a truncated index. The context-management system needed managing.\n\n**One real behavior bug that shipped to the branch**: slice 251's `+G` empty-echo — the self-settable-umode allowlist and the mode-diff allowlist were maintained as two separate hand-copied letter sets, they drifted, and setting `+G` echoed an empty mode change. The fix was the same medicine as everything else: replace the paired copies with one source of truth and a structural invariant test. It's the \"copies go stale\" theme again, in production code instead of tests.\n\nFor the blog post, the lineage-confusion story is the one I'd promote to a full section — it's the only one where the failure is *specifically about how LLMs work* rather than software being hard, and it sharpens your supervision thesis: the oracle catches wrong bytes, but wrong *priors* needed an adversarial review step, a different tool. The harness-fights-back cluster fits as a compact paragraph in your testing section, and the time-bomb cluster is one paragraph of connective tissue (\"the agent's recurring sin, in tests and code alike: maintaining copies of facts\")."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":27,"cache_read_input_tokens":165226,"output_tokens":3303,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":27,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":3303,"cache_read_input_tokens":165226,"cache_creation_input_tokens":27,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":27},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjpyxTdbw2ycttaYfrCn","type":"assistant","uuid":"a6519852-07d5-412b-b8b2-eca6bd2179d8","timestamp":"2026-07-06T00:07:11.796Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 313 313 + {"parentUuid":"a6519852-07d5-412b-b8b2-eca6bd2179d8","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"b9d7f84f-f35c-4638-8b17-f80401700e38","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":45},"type":"attachment","uuid":"7728f403-06a4-48f3-a08a-20cb59eb8218","timestamp":"2026-07-06T00:07:11.973Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 314 314 + {"parentUuid":"7728f403-06a4-48f3-a08a-20cb59eb8218","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":45},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":7}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-06T00:07:11.974Z","uuid":"c649918d-df98-42c3-af98-edb956086a1e","toolUseID":"b9d7f84f-f35c-4638-8b17-f80401700e38","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 315 315 + {"parentUuid":"c649918d-df98-42c3-af98-edb956086a1e","isSidechain":false,"type":"system","subtype":"away_summary","content":"You're outlining a blog post about the Claude-driven C-to-Rust IRC daemon experiment, and I've been mining memories and the C tree for material.

question to ask before writing, because the honest split between \"earned\" and \"lucky\" is what makes the method section credible. Here's my read, sorted by how load-bearing the luck was:\n\n## Genuine luck — properties of the problem you didn't engineer\n\n**1. The seam already existed.** Every `foo.c` shipped a `foo_ext.h` declaring its exact extern API — 41 headers, ~417 symbols, a ready-made per-module ABI contract — and command dispatch was already a function-pointer table. The strangler pattern *requires* a seam, and the 1990s authors' header discipline handed you one. On a codebase without that convention, defining each module's boundary would have been per-file archaeology. This is the single biggest piece of luck and worth saying plainly: the method's cost depends enormously on whether your legacy code accidentally documented its own contract.\n\n**2. Every variadic function had a `va_list` sibling.** Stable Rust can't define `extern \"C\"` variadics — that wall was absolute. The only reason thin trampolines worked is that the C authors had already split each `sendto_one(fmt, ...)` into a `vsendto_one(fmt, va_list)` core the trampoline could target. Lots of 90s C never bothered. Without the v-siblings, the wall arrives in P3 instead of P8 and the \"faithful port\" gets much less faithful.\n\n**3. The C daemon turned out deterministic enough to byte-diff.** You chose IRC for the diffable wire format (earned), but the *determinism* was discovered, not guaranteed: sequential UIDs, hash buckets that follow arrival order, wire output that's stable given a serialized client script. It took clock-masking and strict serialization, but only that. A daemon that iterated a hash table in pointer order would have made golden testing a canonicalization nightmare. Related luck: in ~700 tests' worth of differential surface, the oracle was provably *wrong* in exactly two places (the STATS varargs garbage) — a 30-year-old C codebase whose undefined behavior almost never reached the wire. That's what 4,597 commits of production hardening buys, and you inherited it for free.\n\n**4. The nastiest subsystems were compiled off by default.** SUMMON/USERS (the utmp/tty-writing machinery) sat behind `#ifdef`s that default off — an entire creepy, unportable subsystem you never had to port. The locked config choice pruned it (earned), but the ifdefs falling where they did was luck.\n\n**5. The bindgen bug had already been fixed upstream.** The libclang-22 AST issue that silently turned `aClient` and thirteen other structs into opaque byte blobs was fixed in bindgen 0.72, released before you needed it. If the timing were six months different, the layout drift-net — the foundation under everything — would have required patching bindgen yourself before the project could start.\n\n**6. You were the right supervisor for this exact codebase.** The moments that required a human overrule — the TS6 reop-wipe divergence, the NJOIN-vs-SJOIN lineage confusion — were catchable *by you specifically* because you spent years maintaining an IRCd. A supervisor without domain knowledge would have accepted the agent's plausible rationale both times. This is luck from the reader's perspective and worth flagging as a limit on generalizability: the method assumes the human can adjudicate domain disputes cheaply.\n\n## Earned wins — things that worked because of how you set them up\n\n**1. The program never stopped building.** The drop-the-`.c`-from-the-build mechanism meant exactly one definition of every symbol existed at all times, so there was never a broken-window period, across the entire migration. That's design, and it's the thing that made \"leave it running on a side monitor\" viable at all.\n\n**2. The harness-first ordering paid for itself repeatedly.** Building P0's differential machinery before porting anything felt like overhead and turned out to be the whole ballgame — every later war story (frozen clock, fakelag, STATS garbage) was survivable *because* there was a gate that turned \"subtle behavioral drift\" into \"red test today.\"\n\n**3. The pivot was cheap because the structure allowed it.** When you retired the in-place-idiomatization plan and forked leveva instead, the two weeks of mechanical porting didn't become sunk cost — it became the oracle. A plan that survives its own major revision without losing prior work is the design working, not luck.\n\n**4. The slice discipline scaled.** 309 slices of failing-test-first with recorded provenance, and the process never collapsed under its own weight — the failures it had (stale comments, stale proptest models) were annoyances, not derailments.\n\n**5. Production surfaced exactly what the tests couldn't, and the system was debuggable when it did.** The desync bugs were only findable on a real network — and when they appeared, the per-server probe technique localized them in minutes. Deploying early was a choice; the payoff was earned.\n\nFor the post, I'd frame it as: the luck cluster is really one meta-point — **this codebase was unusually strangler-friendly, and you should audit yours for the same properties before trying this** (extern-API headers, va_list siblings, deterministic output, a diffable surface). That converts \"I got lucky\" from a confession into the most actionable section of the post: it's literally the reader's pre-flight checklist."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":17,"cache_read_input_tokens":168556,"output_tokens":3576,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":17,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":3576,"cache_read_input_tokens":168556,"cache_creation_input_tokens":17,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":17},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjqsCsEJP4HzLNF5xLws","type":"assistant","uuid":"a3730f74-cd41-4176-9cb5-4b3753517832","timestamp":"2026-07-06T00:18:50.760Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

found several relevant issues related to rust-bindgen and forward-declared structs:\n\n## Key Findings\n\nBindgen should be able to detect forward declarations and generate opaque enums if appropriate, instead of structs with an address byte. To do this, it should check `clang_getCursorDefinition()` and `clang_isCursorDefinition` to check whether what is being scanned is a definition, mark the generated type accordingly, and perform the proper codegen steps.\n\nThere is also a specific issue (Issue #2106) that demonstrates a problem with `typedef struct` declarations. When handling `typedef struct Foo {} Foo;` with the `--opaque-type Foo` flag, bindgen can generate invalid code.\n\nAdditionally, Issues can occur with forward declared pointer types, where a forward declaration like `struct alt_RotationLayout* ptr` appears before the full struct definition in typedef statements.\n\n## Related Libclang Issues\n\nThe bindgen project relies on libclang for parsing. Some old libclang versions seem to return incorrect results in some cases for non-mangled functions. This suggests that regressions can be caused by libclang behavior changes when handling forward declarations and typedef struct combinations.\n\nIf you're looking for a specific issue or bug report, you may want to check the rust-bindgen GitHub issues directly at https://github.com/rust-lang/rust-bindgen/issues for more recent developments.\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks."}]},"uuid":"f892dd43-68d3-4191-ba36-48cc03b0dda7","timestamp":"2026-07-06T00:25:42.144Z","toolUseResult":{"query":"rust-bindgen issue forward-declared struct typedef opaque empty struct libclang regression","results":[{"tool_use_id":"srvtoolu_01PjY3kd5LJLZdzjur3pyi1E","content":[{"title":"Detect forward declarations and generate opaque enums for them. · Issue #62 · rust-lang/rust-bindgen","url":"https://github.com/rust-lang/rust-bindgen/issues/62"},{"title":"Builder in bindgen - Rust","url":"https://docs.rs/bindgen/latest/bindgen/struct.Builder.html"},{"title":"bindgen 0.70.1 - Docs.rs","url":"https://docs.rs/crate/bindgen/latest/source/src/ir/comp.rs"},{"title":"allowlist with opaque_type on `typedef struct A {} A;` generates invalid code · Issue #2106 · rust-lang/rust-bindgen","url":"https://github.com/rust-lang/rust-bindgen/issues/2106"},{"title":"bindgen::Builder - Rust","url":"https://www.willusher.io/ispc-rs/bindgen/struct.Builder.html"},{"title":"GitHub - rust-lang/rust-bindgen: Automatically generates Rust FFI bindings to C (and some C++) libraries. · GitHub","url":"https://github.com/rust-lang/rust-bindgen"},{"title":"Duplicate definitions with forward declared pointer types · Issue #1864 · rust-lang/rust-bindgen","url":"https://github.com/rust-lang/rust-bindgen/issues/1864"},{"title":"Treating a Type as an Opaque Blob of Bytes - The bindgen User Guide","url":"https://rust-lang.github.io/rust-bindgen/opaque.html"},{"title":"bindgen - crates.io: Rust Package Registry","url":"https://crates.io/crates/bindgen"},{"title":"Introduction - The bindgen User Guide","url":"https://rust-lang.github.io/rust-bindgen/"}]},"Based on the search results, I found several relevant issues related to rust-bindgen and forward-declared structs:\n\n## Key Findings\n\nBindgen should be able to detect forward declarations and generate opaque enums if appropriate, instead of structs with an address byte.

no upstream issue to cite — so I built you something better: a verified, minimal reproduction. The memory's claim checks out exactly, on this machine, with a 50-line header:\n\n| | libclang 18 | libclang 22.1.8 |\n|---|---|---|\n| **bindgen 0.70.1** | all structs complete | **all 5 forward-typedef'd structs opaque** (`pub _address: u8`) |\n| **bindgen 0.72.1** | — | all structs complete, full fields |\n\nThe trigger is precisely the ircd pattern: `typedef struct Client aClient;` forward-typedefs at the top, mutually-referencing definitions later in the same header. Under bindgen 0.70.1 + libclang 22, every one of `SLink`, `User`, `Client`, `Channel`, `LineItem` degrades to an opaque stub; same bindgen with libclang 18 is fine, and 0.72.1 with libclang 22 emits `Client` with all its fields (`next`, `prev`, `user`, `namebuf: [c_char; 16]`, …). So it's a genuine bindgen×libclang interaction — the bug needs both the old bindgen *and* the new libclang, which is why it's nasty: upgrading your *OS's clang* breaks your *Rust build*.\n\nThe repro is `scratchpad/repro/mini.h` plus:\n\n```sh\ncargo install bindgen-cli --version 0.70.1 --root b070 --locked\ncargo install bindgen-cli --version 0.72.1 --root b072 --locked\nLIBCLANG_PATH=/home/linuxbrew/.linuxbrew/lib b070/bin/bindgen mini.h -- -x c | grep -c '_address: u8' # → 5\nLIBCLANG_PATH=/home/linuxbrew/.linuxbrew/lib b072/bin/bindgen mini.h -- -x c | grep -c '_address: u8' # → 0\n```\n\nFor the blog, I'd cite it as: \"bindgen 0.70 paired with libclang 22 silently resolves forward-declared typedef'd structs to opaque byte blobs; I couldn't find an upstream issue describing the pairing — here's a minimal repro — and 0.72 emits them correctly (likely fixed incidentally around [#2880's opaque-type rework in 0.71](https://github.com/rust-lang/rust-bindgen/blob/main/CHANGELOG.md)).\" Honest, verifiable, and the repro link does more work than a citation would.\n\nTwo follow-ups, your call: I can commit the repro into the repo (say `docs/repro/bindgen-opaque/`) so the blog has a stable link — the scratchpad is ephemeral — and/or file it upstream against rust-bindgen as a regression report with the minimal header; even though 0.72 fixes it, they may want the test case, and an issue number would give you the clean citation after all.\n\nSources: [bindgen CHANGELOG](https://github.com/rust-lang/rust-bindgen/blob/main/CHANGELOG.md), [rust-bindgen #62](https://github.com/rust-lang/rust-bindgen/issues/62), [rust-bindgen #1864](https://github.com/rust-lang/rust-bindgen/issues/1864), [rust-bindgen #2106](https://github.com/rust-lang/rust-bindgen/issues/2106), [rust-bindgen #3162](https://github.com/rust-lang/rust-bindgen/issues/3162)"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1267,"cache_read_input_tokens":187898,"output_tokens":1799,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1267,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":1799,"cache_read_input_tokens":187898,"cache_creation_input_tokens":1267,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1267},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjrfC2ucKLebLwtaHXNP","type":"assistant","uuid":"faa488cd-49f3-4c51-ab26-f3b07a4eeed4","timestamp":"2026-07-06T00:28:44.972Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 406 406 + {"parentUuid":"faa488cd-49f3-4c51-ab26-f3b07a4eeed4","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"9129d5e6-d08d-496c-8571-7e84896cc555","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":63},"type":"attachment","uuid":"010242ae-6d19-41a9-aba3-a89c6a4e1d25","timestamp":"2026-07-06T00:28:45.164Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 407 407 + {"parentUuid":"010242ae-6d19-41a9-aba3-a89c6a4e1d25","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":63},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":11}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-06T00:28:45.165Z","uuid":"f6d2dba8-4f35-4edd-b5d9-1121033daa87","toolUseID":"9129d5e6-d08d-496c-8571-7e84896cc555","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 408 408 + {"parentUuid":"f6d2dba8-4f35-4edd-b5d9-1121033daa87","isSidechain":false,"type":"system","subtype":"away_summary","content":"You're outlining your blog post about the Claude IRC-daemon-port experiment.

The summary below covers the earlier portion of the conversation.\n\nSummary:\n1. Primary Request and Intent:\n The user (Xe Iaso, me@xeiaso.net) is writing a human-authored blog post titled \"My vibecoding experiment of an IRC daemon in Rust\" about their completed experiment: using Claude Opus to port IRCnet ircd 2.11 (C) to Rust as a faithful mechanical port, then using that port as a correctness oracle for a greenfield idiomatic-Rust daemon (\"leveva\"). The conversation is a series of editorial/research requests supporting this blog post, plus one forward-looking feature-gap analysis:\n - Build/refine a bullet outline for the post; identify what's *genuinely* interesting vs filler\n - Mine docs/claude-memory/ for blog-worthy stories (done via 3 Explore agents)\n - Get exact repro commands for the \"oracle was wrong\" STATS varargs bugs in the C code\n - Have \"a few Opus agents\" dig through var/ircd (a C-tree checkout) to catalog technical debt from code predating the (modern) internet (done via 4 Opus agents)\n - Verify the C daemon really has no native TLS\n - Review the expanded outline draft; advise what to change/drop\n - Spawn two Haiku agents: IRCv3 ecosystem adoption survey + leveva IRCv3 implementation audit; synthesize into a TODO list\n - Identify other big problems the agent ran into during the project\n - Identify where the user got lucky vs what went well by design\n - Most recently: get a citation for the bindgen bug (0.70 + libclang 22 → opaque structs, fixed by 0.72)\n\n2. Key Technical Concepts:\n - Two-stage strangler-fig migration: C → mechanical Rust port (oracle #1 = C) → greenfield leveva (oracle #2 = mechanical port), then both scaffolds deleted (P12, 2026-06-13)\n - \"An oracle doesn't need to be idiomatic, it just needs to keep passing tests\" — why in-place cleanup (P9) was retired\n - objcopy `--redefine-syms`/`--prefix-symbols=cref_` differential testing (C + Rust versions of same fn in one binary); limits: static fns have no oracle symbol; link_anchor needed to keep rlib alive\n - Golden L2 wire-diffing; frozen-clock trap (LD_PRELOAD fixed time() freezes event loop; fix = real clock + output canonicalizer)\n - Variadic wall: stable Rust cannot define extern \"C\" variadic fns; ~25 C trampolines until P8; wire! raw-byte builder instead of format!

Current Work:\n Answering \"can I get a citation for that bindgen bug?\" Web searches found no matching upstream rust-bindgen issue (only cousins: issues #62, #1864, #2106, #3162; 0.72.0 changelog entry \"Remove warning for opaque forward declarations\" is adjacent but not the fix). I built a minimal reproduction instead: wrote `scratchpad/repro/mini.h` mimicking `common/struct_def.h` (forward typedefs before definitions, three typedef names for one struct), installed bindgen-cli 0.70.1 and 0.72.1 into scratchpad, and ran the matrix with `-- -x c`:\n - `LIBCLANG_PATH=/home/linuxbrew/.linuxbrew/lib` (libclang 22.1.8) + bindgen 0.70.1 → **5** `_address: u8` opaque stubs (SLink, User, Client, Channel, LineItem)\n - `LIBCLANG_PATH=/usr/lib/llvm-18/lib` + bindgen 0.70.1 → **0**\n - libclang 22 + bindgen 0.72.1 → **0**, `pub struct Client { pub next: *mut Client, pub prev: *mut Client, pub user: *mut anUser, pub name: *mut ::std::os::raw::c_char, pub namebuf: [::std::os::raw::c_char; 16usize], ...` complete\n The final verification command had just returned when the summary request arrived; the result has NOT yet been reported to the user.\n\n9. Optional Next Step:\n Report the reproduction to the user as the answer to \"can I get a citation for that bindgen bug?\": there is no citable upstream issue (searched changelog + tracker; closest are #62/#1864/#3162 and the 0.72.0 line \"Remove warning for opaque forward declarations\"), but the claim is now proven by a 50-line minimal testcase — bindgen 0.70.1 + libclang 22.1.8 emits 5 opaque `_address: u8` structs from forward-typedef'd-then-defined C structs, while the same bindgen with libclang 18 and bindgen 0.72.1 with libclang 22 both emit complete structs. Present the repro (mini.h + three commands + outputs) as the blog citation, include the web sources used (per WebSearch requirements: the rust-bindgen CHANGELOG and issue links), and offer: (a) filing the minimal testcase upstream isn't needed since 0.72 fixed it, but the repro can be committed to the repo or gisted for the blog to link; (b) the still-open offer to correct p5-s2s-stats-flake.md (STATS ? vs STATS m) stands.\n\nIf you need specific details from before compaction (like exact code snippets, error messages, or content you generated), read the full transcript at: /home/xe/.claude/projects/-home-xe-Code-xeiaso-net-ircd-rs/f2966b3c-92d4-4c1a-bdd8-7e37aed36c69.jsonl\nContinue the conversation from where it left off without asking the user any further questions.

These are C headers that use `class` as a struct field name (`common/class_def.h:25`, `common/struct_def.h:323`) and the `register` storage class — both are C++ errors; clang's C++ recovery leaves structs incomplete.

Here's what I have so far:\n\n* The end product: Leveva \n * Leveva is an IRC daemon written in Rust using Tokio and rustls. \n * It is compliant with IRCv3, matching the most common specifications implemented in the wild including the [`chghost` spec I wrote](https://ircv3.net/specs/extensions/chghost). \n * Leveva uses a standard configuration language: KDL \n * [https://kdl.dev/](https://kdl.dev/) \n * This means that the configuration looks like something reasonable instead of a handrolled nightmare like ircd.conf or however you would describe charybdis' newconf. \n * TODO: add samples \n * Leveva has TLS support including terminating websockets \n * Modern web clients use websockets to connect to IRC, this makes connecting to IRC from webapps trivial."},"uuid":"54a64461-d9f9-4144-bddd-ef126adbefa0","timestamp":"2026-07-06T00:36:24.311Z","permissionMode":"auto","origin":{"kind":"human"},"promptSource":"typed","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"}

my read. The draft is accurate but it's a spec sheet, and it's the *last thing the reader sees* — the ending needs to prove leveva is real and land the experiment's thesis, not just enumerate features. Three structural notes, then per-bullet feedback, then numbers you can steal.\n\n**1. The biggest missing bullet: it runs in production.** You've been running leveva on ShadowNET (irc.xeserv.us). That's the single most persuasive fact in the whole post — \"the vibecoded daemon is serving my actual IRC network right now\" beats any feature list. It also earns the war stories from earlier (the bare-UID desync, the netsplit merge) because those were found *in prod*. Lead the section with it.\n\n**2. Milk your callbacks.** Two of your three bullets are payoffs to setups you already made earlier in the post, so phrase them as callbacks:\n- TLS: earlier you establish the C daemon has *no* TLS — the `T` port flag is purely declarative (\"you must ensure that it actually is -- mh 2020-04-27\") and real deployments use stunnel. So this bullet writes itself: \"Remember stunnel? Leveva terminates TLS natively — client ports, WebSockets, and even server-to-server links.\"\n- KDL: your setup was the ircd.conf single-letter colon-format nightmare. The sample you're planning should be a **side-by-side** — the same listener + oper block as a `P:`/`O:` line and as KDL. That contrast is worth more than any prose describing it.\n\n**3. \"Compliant with IRCv3\" isn't quite a thing** — IRCv3 is a menu of extensions, not a compliance target, and pedantic IRC people are exactly the readers you'll have. Say what it actually is: leveva implements **27 IRCv3 capabilities**, all behavior-wired (no advertise-but-ignore), covering everything in the widely-deployed tier. The chghost personal touch is great, keep it. But the *reader-visible* payoff is the bouncer-less quartet, which deserves its own sub-bullet: `draft/chathistory` + event-playback + `draft/read-marker` + `echo-message`/`labeled-response` means you can close a web client, reopen it, and your channel history and read position are just there — no ZNC. And one sentence on the privacy stance preempts the obvious reaction: channel history lives in SQLite, but user-to-user DMs are *never* stored, by hard rule.\n\nNumbers, if you want a \"by the numbers\" beat (all fresh from the repo just now):\n\n- ~157k lines of Rust (leveva + its native iauth subcrate, tests included)\n- 3,764 test functions\n- 309 recorded feature slices in the progress log\n- 77 client command handlers, each with an embedded help page (91 pages, and a test enforces that pairing in both directions)\n\nOther candidates if you want one more bullet — I'd pick at most one to avoid spec-sheet drift: charybdis-grade operator tooling (K-lines/D-lines persisted in SQLite, hot REHASH of nearly everything, flood penalty/fakelag), or S2S details (TLS links, all extensions tunneled through `ENCAP` so 1997-era peers don't SQUIT you), or Prometheus metrics built in.\n\nLast thing: don't end the post on a bullet. After the feature list, close the loop on your thesis in a sentence or two — the mechanical port existed only to be an oracle, the oracle and all the differential scaffolding got deleted on June 13, and what's left is a standalone Rust daemon that no longer knows the C code ever existed. That's the strangler fig completing, and it's your ending."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":211,"cache_read_input_tokens":51242,"output_tokens":2121,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":211,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":2121,"cache_read_input_tokens":51242,"cache_creation_input_tokens":211,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":211},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CcjsMiKg66UwbDcSrDZjV","type":"assistant","uuid":"062154a6-15d8-4132-8fbd-ea6beb89d553","timestamp":"2026-07-06T00:37:58.889Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"} 453 453 + {"type":"last-prompt","lastPrompt":"What is a good summary of the leveva project for the end of the blogpost?

If you are not interested in reading about this, please click away. I will not be reading complaints, so please don't bother posting them. \n* Early June I decided to see how effectively Claude Opus could port an IRC daemon to Rust, then use that Rust version of the program as a correctness oracle to write a new IRC daemon in idiomatic Rust. \n * Software rewrites in other languages fail. This is a known fact. Any time someone tells you that they're doing a big rewrite in Rust, they're going to fail. It is a matter of when, not if. \n * As codebases get bigger, more legacy behaviour and workarounds get ossified into place. This behaviour is lost in rewrites and ends up making integration with third parties difficult or impossible. \n * The only exception to this is when you do a [Strangler Fig migration](https://martinfowler.com/bliki/StranglerFigApplication.html). This is when you start to modernize a codebase by gradually replacing codepaths with a new version of the same functionality. \n * I ended up wondering if existing off the shelf tools could be good enough to help rewrite a program in Rust by building detailed context about a C codebase by mechanically translating it to Rust and then using that to do a full greenfield rewrite. \n * This started out as an experimental offshoot of my [\"No way to prevent this\" say users of only language where this regularly happens](https://xeiaso.net/shitposts/no-way-to-prevent-this/memory-safety/CVE-2026-8461/) blogposts where I've been wondering if existing tools off the shelf are good enough to start moving our existing C code to Rust \n * Mimi\\\\ Full disclosure: this post was written by a human with thoughts and feelings, but part of the outlining and drafting process included loading all of the chat logs for this repository into an AI agent to help surface important parts of this process. \n* The project I chose: ircnet/ircd \n * Why IRC? \n * IRC is a very simple protocol with an innumerable number of edge cases. \n * I have a long history of maintaining IRC server software. \n * This combination gives me a unique insight into how this protocol works and fails in practice. I'm kind of out of practice as I [stopped working on an IRCd in 2019](https://xeiaso.net/blog/deprecation-notice-elemental-ircd-2019-02-11/). \n * The exact IRC daemon I maintained was [way deep down the IRCd family tree](https://github.com/grawity/irc-docs/blob/d6941670a9013cfe81f0493ef1ddf28cfe6585b9/family-tree.txt#L69). I didn't want to pick it because it's based on [ircd-ratbox](https://ratbox.org/), which has a lot of complicated multi-platform support features that are frankly irrelevant in modern setups. \n * I wanted to pick an IRC daemon that was just complicated enough to exercise a lot of the issues you'd see in the real world, but not so complicated that the forest would be lost for the trees. \n* Ground rules \n * When I set out to do this, I set a few ground rules: \n * The existing C code is a [correctness oracle](https://en.wikipedia.org/wiki/Test_oracle), all changes will be compared against the correctness oracle to ensure that they are accurate. \n * I wanted to do as little action as possible and leave this running on a side monitor. \n * Eventually I had to move this from my tower to another machine because claude running tests could cause my tower to OOM, crashing my games \n * When converting the C to Rust, do the migration both outside-in and inside-out. \n * The main() function became Rust as early as possible, it mostly converted arguments/envvars/flags to the right things in C and kicked off the C code \n * When doing the greenfield rewrite, use the Rust version of the IRC daemon as a line protocol correctness oracle \n * The oracle does not have to be pretty, it just has to work enough to help ensure tests pass \n * All the claude code logs are committed to the repository \n * I don't know what value these sessions will have in the future, but out of the interest of full transparency and opening this data for future analysis, I have committed all the Claude Code logs to the repo: \n * [https://tangled.org/xeiaso.net/ircd.rs/tree/master/.claude](https://tangled.org/xeiaso.net/ircd.rs/tree/master/.claude) \n * Please let me know if you find them useful\\! They may be useful in adding to datasets for distilling Opus features into lesser models. \n * Leaving the IRCNet team alone \n * They don't know I'm doing this experiment. I don't want them to have to care that I have done this experiment. Leave them alone. They have enough to work on already. \n* The state of the codebase \n * Look, I'm not here to shit-talk the ircnet team for what they're building/have built. They have to exist under unimaginable amounts of technical debt. \n * I'm also not about to say that this codebase is a paragon of technical excellence either. This is a codebase that is older than I am and in some places it really shows. \n * Again, leave them alone. \n * The configuration file format is completely handrolled. Way back in the before times the configuration file used the `:` character for separating arguments, EG: (embed sample config file) \n * This ended up having a lot of problems when IPv6 deployment became more common, as IPv6 addresses use colons in them. \n * [https://github.com/ircnet/ircd/pull/9\\#issuecomment-2496425611](https://github.com/ircnet/ircd/pull/9#issuecomment-2496425611) \n * This also means that migrating from an old-stye config with pipes in ban reasons to the new style config can cause your configuration file to not validate properly, which could cause problems. \n * IRC line output is a buffer overflow waiting to happen \n * The output path of IRC messages is a shared global 2048 character buffer that is length-checked *after* any writes are made. This single pattern is so egregious that it's a peak example of why we need to start abandoning C as an industry. \n * This codebase predates POSIX being widely accepted. \n * POSIX standardized behaviour across dozens of mutually incompatible UNIX environments. The only way to figure out the exact behaviour of your system was to test it, potentially thousands of times. \n * This is generally why it uses the autoconf behaviour of generating and compiling portability oracles, this is how it knows which set of compatibility hacks it needs to enable at compile time. \n * This includes but is not limited to a hand-optimized version of `memcmp` (memory compare) that is only used if your system's C library treats bytes as *signed*. \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/support/configure.in\\#L599-L611](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/support/configure.in#L599-L611) \n * [https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/support.c\\#L1125](https://github.com/ircnet/ircd/blob/e6d60c4f7cf0fdeca9559ec0b2672ccfba029afc/common/support.c#L1125) \n * I'm certain that the ANSI C standard fixed this before most people currently working in the tech industry were born \n * Ircd has load-bearing dependencies on a technique called partial struct allocation \n * A pithy way to describe how C works is that in C, types don't exist. All that really exists is machine words. This is true for integers, boolean values, floating-point numbers, and data structures. \n * Copy things from here: [https://claude.ai/chat/6e35150e-110d-4e18-8961-c81efc7e25a2](https://claude.ai/chat/6e35150e-110d-4e18-8961-c81efc7e25a2) \n * At a low level, when you are allocating memory for a structure such as information about IRC clients there is no reason that you need to allocate *the entire struct* at once. \n * Maybe every client struct has details that aren't relevant all of the time, such as a local send queue / receive queue. You wouldn't need to care about those for *remote* clients, right? \n * The downside is that when you do this, you *need* to be careful to *never* reference those fields when they are in a context where they aren't allocated, otherwise you are walking outside of the struct into random memory. \n * This is a classic example of an out of bounds read which can lead to security issues. \n * Something something safety level: landmines afoot \n * In Rust you would just use an enumeration that stores the local-only values or the remote-only values. \n * Why would you want to do this? Ram prices shot up by 300% after big industry ate up all the cheap high-capacity chips. I wonder what current crisis this reminds you of. \n * Any hack you could think of to save ram saved hilarious amounts of money at the cost of creating technical debt we have yet to pay down today. \n * TLS is external to the IRC daemon \n * Back when I maintained elemental-ircd, it would spawn a number of ssld subprocesses that handled taking TLS sockets and outsourced the encryption/decryption. \n * Again, you want to do this because at the time it was implemented, TLS encryption/decryption was time-consuming and \"slow\" across the scale of IRC network deployments. Outsourcing this to a subprocess made the IRC daemon more snappy. \n * With ircnet/ircd, all TLS termination and implementation was expected to be done outside of the IRC daemon via utilities like [stunnel](https://www.stunnel.org/). Marking and enforcement of clients/server links being made over TLS is done via the honor system. \n * If a plaintext client manages to connect to the internal \"TLS\" port, they will be marked as connecting over TLS even though they aren't. \n * All global state is globally mutable \n * Again, this is not as big of a problem in a single-threaded environment like ircd, but it means that any \"multithreaded\" features have to become subprocesses instead of async tasks or threads. \n* Managing the agent \n * One of the main problems with big scale things like this is that AI agents don't largely have much memory between invocations. Every time they start over from scratch. \n * In order to mitigate this, I made the agent write and maintain a [PLAN.md](https://tangled.org/xeiaso.net/ircd.rs/blob/master/PLAN.md) covering its current state and an idea of what should come up next. \n * I also created a [command-cluster-port](https://tangled.org/xeiaso.net/ircd.rs/blob/master/.claude/skills/command-cluster-port/SKILL.md) skill that covered how to port a single \"cluster\" of command implementations from C to Rust and record progress. \n * Every invocation also created [a plan file](https://tangled.org/xeiaso.net/ircd.rs/tree/master/docs/superpowers/plans) using the [superpowers plugin](https://github.com/obra/superpowers). I've been using superpowers for a while and am happy with it, so I wanted to see how it would scale when being left to its own devices like this experiment. \n * At the core was me running this prompt in a loop:\n\n```\nPlease read @PLAN.md and implement the next step, read @.claude/skills/command-cluster-port/SKILL.md for guidance on how to plan and record it.\n```\n\n * Every so often while working or playing games, I'd look over to see if it was done and then if it was, create a new session and submit that prompt again. \n * I encouraged the model to use the memory subsystem. As an additional transparency measure, I committed the generated memories to the repo: \n * [https://tangled.org/xeiaso.net/ircd.rs/tree/master/docs/claude-memory](https://tangled.org/xeiaso.net/ircd.rs/tree/master/docs/claude-memory) \n* The problems I ran into \n * After a while, the process got complicated and big enough that it ended up using *a lot* more memory than I had predicted. Turns out compiling and running thousands of copies of the IRC server in parallel uses a lot of RAM. \n * This mainly surfaced as Claude doing big test runs and causing my tower to run out of RAM. \n * I ended up solving this by moving the process to an ARM box and having a good enough experience with the process that I'm probably going to move all my software development there. \n * Moving this from amd64 to arm64 caused strange issues around the type of c characters. \n * Apparently C character signedness isn't standardized, it's implementation specific \n * On x86-64 with the System V ABI, C characters are defined as signed integers (range \\-128-127) \n * On aarch64 with the ARM standard ABI AAPSC64, C characters are defined as unsigned integers (range 0-255) \n * This ended up causing some portability issues that were easily fixed with clever use of `sed` to replace `i8` char definitions with the `c_char` metatype that had the Rust stdlib resolve down to the correct type \n * The model's training data ended up fighting the codebase \n * The most common IRC daemons in the wild (and thus in the training data) are all descended from the Ratbox subfamily. This means that details about how Ratbox and the TS6 linking protocol are codified into the model. \n * For example, the TS6 channel join command is `SJOIN` which includes details like the channel timestamp. IRCNet's IRCd uses `NJOIN` which is a far different verb with very different semantics. \n * As a result of this, Claude kept insisting that any divergences from Charybdis or other TSora IRCds were bugs and protocol divergences. \n * I ended up allowing this because Charybdis was actually one of the best IRC daemons. I will accept no complaints about this assertion. \n * The test harness kept fighting back \n * The linker kept discarding the Rust implementation of the irc daemon from test binaries because there was no direct reference to them in the compiled output. Every test needed a link anchor function that did spooky linker magic to force rustc to actually compile in the needed functionality. \n * Parallel test execution raced on the C global values in ways that ended up with [many, many test .rs files](https://tangled.org/xeiaso.net/ircd.rs/tree/master/leveva/tests) which could be run in parallel with [cargo-nextest](https://nexte.st/). \n * The differential harness had its own portability bugs, including but not limited to that handrolled implementation of memcmp() I mentioned before reaching forward in time through the feature-detection maze and breaking tests written in Rust in 2026\\. \n* Where I got lucky \n * This project was accidentally ideal for a strangler fig migration: \n * All functionality was implemented with C headers pointing to functions, so the underlying implementation could be gradually strangled out with ifdefs and defining the relevant functionality in Rust. \n * The parts that didn't have their own C headers were in a big ol' vtable for dispatching from client command verb to command handler functions. It was easy for the agent to progressively rip out seams from the C side and add them into the Rust side. \n * The project was able to build at every commit. This means that you can easily prove things work because the project builds and tests pass. \n * Ircd is deterministic enough to byte-diff when proving functionality works. \n * A lot of the testing of the ported code involved having clients connect to servers and sending commands to get the expected results. The IRC daemon in normal operation is detereminstic enough to do byte-level diffing. \n * This ended up becoming the core of the \"golden test\" subsystem that leveva uses in CI to ensure things are all working. \n * This also meant that \n * I had years of experience developing IRC daemons, so I was able to easily be able to look at behaviour and know if it is \"correct-shaped\" at a glance. \n * There were a few moments where behaviour I knew was incorrect was programmed in, and when I took a look I flagged it and told the agent which path to take instead. This made me an ideal supervisor for this project as my domain knowledge was given the chance to shine. \n* The end product: Leveva \n * Leveva is an IRC daemon written in Rust using Tokio and rustls. \n * It is compliant with IRCv3, matching the most common specifications implemented in the wild including the [`chghost` spec I wrote](https://ircv3.net/specs/extensions/chghost). \n * Leveva has TLS support including terminating websockets \n * Modern web clients use websockets to connect to IRC, this makes connecting to IRC from webapps trivial. \n * TODO: add samples for listening normally and over TLS with ircd.conf and leveva KDL \n * Oh yeah, I use something standard instead of a handrolled custom config format like ircd.conf or Charybdis' newconf \n * I'm running it in production at [https://althyk.yolo-swag.com/](https://althyk.yolo-swag.com/) \n * It connects to my homelab over a WireGuard link \n * While it was being written, it used the Rust port as a correctness oracle that was eventually discarded. \n * Link to [leveva.yolo-swag.com](http://leveva.yolo-swag.com) once that's up \n * Link to binary downloads \n * If you find issues with it, please file them on Tangled \n * https://tangled.org/xeiaso.net/ircd.rs/issues"},"uuid":"a8374d65-7439-4a35-8cac-d5ff83ff611a","timestamp":"2026-07-06T01:38:53.203Z","permissionMode":"auto","origin":{"kind":"human"},"promptSource":"typed","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"} 461 461 + {"parentUuid":"a8374d65-7439-4a35-8cac-d5ff83ff611a","isSidechain":false,"attachment":{"type":"file","filename":"/home/xe/Code/xeiaso.net/ircd.rs/.claude/skills/command-cluster-port/SKILL.md","content":{"type":"text","file":{"filePath":"/home/xe/Code/xeiaso.net/ircd.rs/.claude/skills/command-cluster-port/SKILL.md","content":"---\nname: command-cluster-port\ndescription: Use when porting a C command-handler translation unit (an ircd/*.c with m_* handlers — channel.c, s_user.c, s_serv.c, s_misc.c, s_debug.c, s_auth.c, …) from C to Rust in the ircd.rs strangler-fig migration (phase P5). Covers the msgtab seam, dropping the .o, and L1+L2 verification.\n---\n\n# Porting a command-handler cluster (P5)\n\n## Overview\n\nP5 ports `ircd/*.c` command-handler TUs to Rust one **cluster** at a time (a connected component of file-`static`s + the `m_*` handlers that share them). The strangler seam is the `msgtab[]` function-pointer table in `parse.rs`. Faithful mechanical port only — no idiomatic redesign (that's P8).\n\n**Core mechanism:** define the Rust symbols (`#[no_mangle] pub extern \"C\"`, exact `*_ext.h` signatures) → add the `.o` to `PORTED` in `ircd-sys/build.rs` → the linker resolves everyone's references to the Rust definitions. Verify with **L1** (data ops, differential vs `cref_`), **L2** (`ircd-golden`, wire-diff vs reference-C from a local client), and **L2-S2S** (`ircd-golden` `boot_s2s` + `Peer`, wire-diff for any server-reachable `IsServer(cptr)` path). All three are required — a cluster with server-reachable branches is **not done** until its S2S test is green.\n\n**REQUIRED BACKGROUND:** superpowers:test-driven-development. Write the failing test first.\n\n**Workflow framing:** drive each cluster as a written plan, not freehand. After scoping (below), invoke **superpowers:writing-plans** to author the per-cluster plan file under `docs/superpowers/plans/` (capturing the classification, the L1/L2 strategy, the port checklist from the `nm` undefined set, and the \"no L2 path\" notes). Then invoke **superpowers:executing-plans** to work the plan with review checkpoints. The numbered Procedure below is the body those two skills wrap — writing-plans produces it, executing-plans walks it.\n\n## Before you start: scope the TU under the locked config\n\nThe config gates (`USE_SERVICES`/`ZIP_LINKS`/`KLINE`/`DEBUGMODE` OFF; `USE_IAUTH`/`TKLINE`/`ENABLE_CIDR_LIMITS` ON) decide what's actually compiled. Check first:\n\n```bash\nnm --defined-only cbuild/<tu>.o | grep -E ' [TtDB] ' # what symbols really exist\ngrep -nE '#if|#ifdef|#ifndef|#endif|^[A-Za-z].*\\(' ircd/<tu>.c # which bodies compile\n```\n\nAn `#ifdef USE_SERVICES`-only function isn't compiled → don't port it. An entirely-`#ifdef`'d-out TU (e.g. `s_zip.o` = 0 symbols) → just add it to `PORTED`, no Rust at all.\n\nOnce scoped and classified (next section), hand the findings to **superpowers:writing-plans** to produce the cluster's plan file before touching any Rust.\n\n## Classify the TU — this decides the L2 strategy\n\nCheck whether the TU's exported symbols appear in `parse.rs`'s `msgtab` (the `m_*` rows):\n\n- **Handler cluster** (`m_join`, `m_who`, `m_squery`, …) — directly client-reachable. L2 drives the command from a local client and diffs the reply. (Worked example: `s_service`.) **If the handler has an `IsServer(cptr)` branch or formats remote-user fields** (`acptr->user->server`, hopcount, SID trailers) — `grep -n 'IsServer\\|MyConnect\\|->user->server' ircd/<tu>.c` — it also needs an **L2-S2S** test (next section + step 7): the standalone client harness can't present a linked peer or a remote user, so those bytes are otherwise untested.\n- **Utility / callee TU** (`s_debug`: `send_usage`/`send_defines`/`count_memory`/`serveropts`; `s_misc`: `exit_client`) — **no `msgtab` entry**. These are called *from* other handlers. You do **not** port the caller. L2 coverage comes from driving the command that calls them (e.g. `STATS u`→`send_usage`, `STATS m`→`count_memory`, `VERSION`/`004`→`serveropts`); confirm the call path with `grep -rn '<fn>(' ircd/`. If no client command reaches it under the locked config, L1 is the gate and you note \"no L2 path\" in the plan.\n\n## Procedure\n\nExecute these steps under **superpowers:executing-plans**, against the plan file written above — each step is a checkpoint, not a freehand edit.\n\n1. **Read `ircd/<tu>_ext.h`** for the exact ABI (mutable `char*`, not `const`). Read the compiled function bodies.\n\n2. **RED — write the L1 differential first** (`ircd-testkit/tests/<tu>_diff.rs`), copying `list_diff.rs`. Cover the *data ops* that need no live socket (allocators, list linkage, self-pointers, lookups). Declare `#[link_name=\"foo\"] fn c_foo` (resolves to Rust) and `fn cref_foo` (oracle); drive both on parallel state; assert identical fields/pointer-walk. **Test the inverse invariants, not just the happy path:** for every add/insert/join also drive the matching remove/part/quit and assert the state is *actually gone* — the member doesn't reappear when re-added, the count decremented, the linked-list node is unlinked, the lookup now misses, a freed slot is reusable. A port that faithfully inserts but botches removal (or leaves a dangling self-pointer) passes a positive-only test and corrupts state in production. The round-trip (join→part→re-join is clean; quit→whowas; alloc→free→alloc) is where mechanical ports drift.\n\n3. **Force RED:** add `\"<tu>.o\"` to `PORTED` in `ircd-sys/build.rs`, `cargo build -p ircd-rs` → expect **undefined symbol** link errors. Cross-check the undefined set against step 1's `nm` list — that's your exact port checklist. After GREEN, confirm resolution: `nm target/debug/ircd | grep -E ' (T|B|D) (sym1|sym2|…)$'` (defined in the binary = came from Rust).\n\n4. **GREEN — port to `ircd-common/src/<tu>.rs`.** `pub mod <tu>;` in `lib.rs` + a `<TU>_LINK_ANCHOR` static added to `link_anchor()`. Patterns: variadic senders via a local `extern \"C\"` block (s_numeric.rs); inline macro helpers (`is_server`, `bad_to`, `my_connect`); `reply(i)`/`me_name()`/`local_base()` helpers from parse.rs; `MyFree`→ libc `free`; interior self-pointers (`cptr->name = svc->namebuf`) via `.as_mut_ptr()`.\n\n5. **L1 green:** `cargo test -p ircd-testkit --test <tu>_diff` → zero diff.\n\n6. **L2 green** (per the classification above): add `ircd-golden/tests/golden_<tu>.rs`. For a **handler cluster**, drive the client-reachable handler paths from a local client. For a **utility TU**, drive the *caller's* command (e.g. `STATS u`). Assert reference-C == Rust byte-identical. Verify the scenario **manually first** (boot both, python a client, `diff`) to pin down which numerics actually fire. If the classification found no client path, skip L2 and say so in the commit/PLAN note.\n\n7. **L2-S2S green — REQUIRED whenever step \"Classify\" flagged a server-reachable path; do NOT defer it.** Add `ircd-golden/tests/golden_s2s_<tu>.rs` using `boot_s2s` + `Peer` (see the S2S harness reference below; `golden_s2s_who.rs` is the worked example). Link a fake peer (`Peer::link()`), `peer.introduce(...)` any remote users the path formats, drive the command, and diff reference-C vs Rust byte-identical. This is the only way to exercise the `IsServer(cptr)` branches and remote-user field formatting (originating server name, hopcount, SID trailers). Boot mode is mutually exclusive with standalone — S2S tests run plain `-t -s` (split mode), standalone `#`-channel tests can't link a peer — so this is a *separate* test file, not an addition to the step-6 file. Skip ONLY if step \"Classify\" found no `IsServer`/remote-field path at all, and say so explicitly in the commit/PLAN note.\n\n8. **Verify + commit:** `cargo build` (0 warnings) + full `cargo test`; conventional commits; update PLAN.md (the P5 row in the phase table) and append the cluster's progress entry to the two P5 logs. **Append via the shell, do NOT Read+Edit** — both logs are large and grow every cluster, so reading one in to Edit it blows out your context window for no reason. Use a heredoc append instead (`>>` so you never load the existing content):\n\n ```bash\n # one-line top-level summary bullet → the per-cluster summary log (split out of PLAN.md)\n cat >> PLAN-P5-progress.md <<'EOF'\n - **P5xx DONE: `<tu>.c` … cluster** (…) — one-sentence scope + mechanism + the L1/L2/L2-S2S gate(s).\n EOF\n\n # detailed entry (one top-level bullet + indented sub-bullets) → the progress log\n cat >> docs/progress-log/p5.md <<'EOF'\n - **<YYYY‑MM‑DD> — P5xx (…) merged.** detailed entry…\n - **Cluster choice / Guard / Config‑resolved body / Classification / L1 / L2 / S2S** — indented sub-bullets matching the existing P5* entries: scope, config findings, faithfulness notes, the L1/L2/L2-S2S verification, and — only when genuinely unreachable — the \"no S2S path\" note.\n EOF\n ```\n\n The one-line top-level bullet goes to **`PLAN-P5-progress.md`** (the per-cluster summary log split out of PLAN.md); the detailed bullet + indented sub-bullets go to **`docs/progress-log/p5.md`**. Neither log lives in PLAN.md — PLAN.md only carries the phase table + a pointer to `docs/progress-log/`. If you must inspect the existing format first, `tail -n 20` the file rather than Read-ing the whole thing.\n\n## Gotchas (each cost real time on s_service)\n\n| Gotcha | Reality |\n|--------|---------|\n| Editing `parse.rs` | **Don't.** It imports the `m_*`/globals from `ircd_sys::bindings`; those declarations resolve to the Rust defs at link once the `.o` is dropped. No msgtab edit needed. |\n| `clashing_extern_declarations` on `sendto_*` | Declare fmt as `*mut c_char` (matches bindgen/other modules), then cast each format literal: `c\"…\".as_ptr() as *mut c_char`. |\n| \"Which handler does a client hit?\" | `msgtab` row = 5 columns by client type `[unreg, client, server, service, …]`. A *registered* client's `SERVICE` hit `m_nop` (col 1), not `m_service`. Check the column before assuming a path is reachable. |\n| Parser rejects before the handler | Min-params (`msgtab` arg 2) → `parse()` sends `461` itself. Bare `SQUERY` never reaches `m_squery`. |\n| Drop vs `_link.o` | If **every** symbol the TU defines is portable → drop the `.o` outright (add to `PORTED`). Only partial-port via a `<tu>_link.o` (`-DPORT_*`) when some symbols must stay C. |\n| L2 test flakiness | All `ircd-golden` boots bind one port → hold `PORT_LOCK` in the `Ircd` guard so cargo's parallel `#[test]` threads serialize. |\n| Happy-path-only tests | A positive assertion (`JOIN` shows the member, the list has the node) is half a test. **Always pair it with the inverse:** part the channel and assert the member is gone from `NAMES`/`WHO` and the count dropped; re-join and assert no stale/duplicate membership; quit and assert the nick is unreachable. This holds at every layer — L1 (list unlink, freed-slot reuse), L2 (`PART`→`JOIN` round-trip is clean), and L2-S2S (a peer `SQUIT`/`QUIT` removes the remote user from channels it was in). Faithful insert + broken removal silently corrupts state and the happy-path test stays green. |\n| Server-burst / S2S paths | The `IsServer(cptr)` branches need a server link — port them faithfully **and** cover them with an `golden_s2s_<tu>.rs` test (step 7). Do **not** \"defer to a future S2S scenario\": the `ircd-golden` `boot_s2s`/`Peer` harness exists now (13 `golden_s2s_*.rs` tests), so the scenario is here. \"Deferred\" is only honest when the path is genuinely unreachable under the locked config. |\n| Config-gated **data** (`serveropts[]`, `replies[]`) | Reproduce it **resolved to the locked config** — flatten the `#ifdef`s to the bytes that actually compile (don't replicate the conditionals). When in doubt dump it from the oracle: `nm`/`gdb` the `cref_*` symbol, or copy the exact compiled string. (P3 did this for `replies[]`.) |\n| Module-private `static` buffers (`debugbuf`, `buf[BUFSIZE]`) | Keep them **private** `static mut [c_char; N]` in the Rust module — they are not ABI. Only the `*_ext.h` symbols get `#[no_mangle]`. Access via `addr_of_mut!`. |\n| ABI signature mismatch | `char *x` → `*mut c_char` (mutable, never `*const`). The function won't link-check against C, so eyeball each param against `*_ext.h`; bindgen's decl in `target/.../bindings.rs` is the source of truth for struct/global types. |\n\n## Reference\n\n- Worked example + the per-cluster decisions: `docs/superpowers/plans/2026-06-02-p5a-s_service.md`.\n- Cluster map (order, statics per TU): `docs/superpowers/specs/2026-06-02-p5-handler-cluster-map.md`.\n- L2 harness internals (DNS off, real clock, config redirect): `docs/superpowers/plans/2026-06-02-p0-l2-golden-harness.md`.\n- **L2-S2S harness** (`boot_s2s`, `Peer::link`, `peer.introduce`, fixtures/`s2s.conf`; determinism findings — sequential local UIDs `000AAAAAA`, peer SID `001B`, standalone-refuses-links): `ircd-golden/src/lib.rs` + worked example `ircd-golden/tests/golden_s2s_who.rs`.

is a strong outline — the structure (thesis → why IRC → ground rules → codebase autopsy → agent management → problems → luck → product) reads as a complete arc, and the codebase-state section is now the best part. Here's what I'd fix, roughly in priority order.\n\n**The biggest omission: the oracle-was-wrong story isn't in here.** The STATS varargs bugs — the C reference printing garbage like `3544950785030750208kB sq` because 32-bit counters were passed under `%lu`/`%ld` format specifiers, only visible for stack-passed arguments — is the single best anecdote you have. It complicates your own thesis (\"the C code is a correctness oracle\" → the oracle itself had bugs, and the differential harness is what *found* them), which is exactly the kind of honest wrinkle that makes these posts credible. It fits under \"The problems I ran into\" or as its own beat right after \"Ground rules\" establishes the oracle premise. Related: the bindgen 0.70 + libclang 22 opaque-structs story you asked me to build a citation/repro for last turn also isn't in the outline — that belongs under the test-harness-fighting-back bullet (it's the same genre: your *tools* betraying you, not the code).\n\n**Accuracy nits:**\n\n- \"Parallel test execution raced on the C global values in ways that ended up with many, many test .rs files\" — but you link to `leveva/tests`, which is the pure-Rust greenfield and has no C globals. The C-global races were in the migration-era harness (solved with a mutex serializing the tests that touch `me`/`local[]`). Leveva's many-small-test-binaries pattern is about process isolation and port conflicts. Either fix the link to point at the migration-era layout or split the two stories.\n- \"Where I got lucky → deterministic enough to byte-diff\" — worth adding the trap you hit here: the *first* attempt at determinism (LD_PRELOAD-pinning the clock to a constant) silently froze the event loop, and the fix was real clock + canonicalizing timestamps out of the output. It rescues this bullet from sounding too easy. Also this section has a dangling sentence: \"This also meant that\" ends mid-thought.\n- \"AAPSC64\" → **AAPCS64**; \"old-stye\" → \"old-style\"; \"detereminstic\" → \"deterministic\".\n- \"Mimi\\ Full disclosure\" — there's a stray \"Mimi\\\" artifact at the start of that bullet.\n\n**Structural notes:**\n\n- \"Where I got lucky\" mixes luck with things that weren't luck. The header-seams and builds-at-every-commit points are genuine luck of project selection. But \"I had years of experience developing IRC daemons\" is the opposite of luck — it's the load-bearing prerequisite. I'd frame that last bullet as the section's turn: \"one of these was not luck,\" and make it your pre-flight checklist moment for readers (\"if you can't glance at output and know it's correct-shaped, this workflow will quietly produce garbage\"). That's the most useful sentence in the post for someone deciding whether to try this.\n- The end-product section: \"compliant with IRCv3\" still isn't a thing — IRCv3 is a menu, not a compliance target, and IRC pedants are your exact audience. \"Implements 27 IRCv3 capabilities, all actually wired to behavior\" is both more accurate and a stronger claim. And the KDL point got demoted to an \"oh yeah\" under the TLS sample TODO — it was its own bullet in your last draft and deserves to stay one; the ircd.conf-vs-KDL side-by-side is your best visual in the whole post.\n- \"While it was being written, it used the Rust port as a correctness oracle that was eventually discarded\" — this is your thesis completing and it's currently one buried bullet. Make it the closing beat, with the concrete fact: the mechanical port, the differential harness, and all the C were deleted on June 13; the final workspace doesn't know the C ever existed. Numbers if you want them: ~157k lines of Rust, 3,764 test functions, 309 recorded feature slices.\n\n**One thing readers will ask that the outline doesn't answer:** how long and how much. \"Early June\" to the June 13 oracle-deletion is about two weeks for the migration itself, with feature slices continuing since. Even a rough token/dollar figure or \"ran on a Claude subscription on a side monitor for N weeks\" will preempt the top comment on every aggregator.\n\nEverything else — the admonition, the leave-IRCNet-alone rule stated twice, the partial-allocation RAM-crisis wink, the stunnel/ssld history — reads well and checks out against the research we did."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":5889,"cache_creation_input_tokens":5968,"cache_read_input_tokens":53574,"output_tokens":5553,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":5968,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":5889,"output_tokens":5553,"cache_read_input_tokens":53574,"cache_creation_input_tokens":5968,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5968},"type":"message"}],"speed":"standard"},"diagnostics":{"cache_miss_reason":{"type":"previous_message_not_found"}}},"requestId":"req_011Ccjx3pxNBvx5a9kUjFpTz","type":"assistant","uuid":"b8c5b6cf-9649-41f2-b7a7-36aceb524e56","timestamp":"2026-07-06T01:40:20.855Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"} 469 469 + {"parentUuid":"b8c5b6cf-9649-41f2-b7a7-36aceb524e56","isSidechain":false,"attachment":{"type":"hook_success","hookName":"Stop","toolUseID":"52cfeb06-de63-4926-a2e0-248d61f22b05","hookEvent":"Stop","content":"","stdout":"{\"continue\":true}\n","stderr":"","exitCode":0,"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":74},"type":"attachment","uuid":"4be8595f-a6f7-467b-9c9a-e1a58280fe81","timestamp":"2026-07-06T01:40:20.955Z","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"} 470 470 + {"parentUuid":"4be8595f-a6f7-467b-9c9a-e1a58280fe81","isSidechain":false,"type":"system","subtype":"stop_hook_summary","hookCount":2,"hookInfos":[{"command":"node \"${CLAUDE_PLUGIN_ROOT}/dist/hooks/stop.js\"","durationMs":74},{"command":"bash \"${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh\"","durationMs":25}],"hookErrors":[],"hookAdditionalContext":[],"preventedContinuation":false,"stopReason":"","hasOutput":true,"level":"suggestion","timestamp":"2026-07-06T01:40:20.955Z","uuid":"13029c4d-4186-4e33-9777-f60a9a3cc323","toolUseID":"52cfeb06-de63-4926-a2e0-248d61f22b05","session_id":"5afb6f54-a28b-4d54-abb4-024e2406a27c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master","slug":"vivid-tickling-moore"}

git commits, writing commit messages, or following version control workflows\n- finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- command-cluster-port: Use when porting a C command-handler translation unit (an ircd/*.c with m_* handlers — channel.c, s_user.c, s_serv.c, s_misc.c, s_debug.c, s_auth.c, …) from C to Rust in the ircd.rs strangler-fig migration (phase P5). Covers the msgtab seam, dropping the .o, and L1+L2 verification.\n- create-blogpost: Use when asked to \"work on another blogpost\" / \"write the next post\" for the docs/blog/ series narrating the ircd.rs C→Rust port. Covers picking a topic, the locked format conventions, grounding claims in real source, the hard paragraph rule, and the mandatory voice passes.\n- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.\n- mind:ask: Ask questions about memories and get context-aware answers\n- mind:recent: Show recent memories and activity timeline\n- mind:search: Search memories for specific content or patterns\n- mind:stats: Show memory statistics and storage information\n- product-management:brainstorm: Brainstorm a product idea, problem space, or strategic question with a sharp thinking partner\n- ralph-loop:cancel-ralph: Cancel active Ralph Loop\n- ralph-loop:help: Explain Ralph Loop plugin and available commands\n- ralph-loop:ralph-loop: Start Ralph Loop in current session\n- ctx-agent-history-search:ctx-history: Search local agent history with ctx\n- mind:memory: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file\n- mind:mind: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file\n- 10x-Team:10x-team: You MUST use this when building projects end-to-end. Orchestrates all 12 team roles — automatically switches between CTO, architect, PM, engineers, SRE, security, DBA, QA, and EM based on the current phase of work. Starts with brainstorming before any implementation.\n- 10x-Team:cto: You MUST use this for strategic technology decisions - build vs buy, architecture direction, resource allocation, technical vision, risk assessment. Evaluates decisions at the intersection of business and technology.\n- 10x-Team:dba: You MUST use this for database decisions - schema design, query optimization, migration planning, indexing strategy, data modeling, and database performance issues.\n- 10x-Team:devops-engineer: You MUST use this for infrastructure and deployment decisions - CI/CD pipelines, containerization, IaC, deployment strategies, environment management, and build automation.\n- 10x-Team:engineering-manager: You MUST use this for team and process decisions - sprint planning, team structure, delivery estimation, process improvements, technical hiring, and engineering team operations.\n- 10x-Team:principal-architect: You MUST use this for system design and architecture decisions - designing systems, choosing patterns, defining boundaries, data modeling, and making structural decisions that are hard to change later.\n- 10x-Team:product-manager: You MUST use this for product decisions - feature prioritization, user stories, roadmap planning, requirement gathering, and defining what to build and why.\n- 10x-Team:qa-engineer: You MUST use this for testing and quality decisions - test strategy, test plans, bug analysis, testing frameworks, coverage gaps, and quality assurance processes.\n- 10x-Team:sde: You MUST use this for hands-on coding tasks - writing features, fixing bugs, implementing APIs, debugging issues, and writing clean production code.\n- 10x-Team:security-engineer: You MUST use this for security decisions - threat modeling, vulnerability assessment, auth/authz design, security review, compliance requirements, and hardening recommendations.\n- 10x-Team:senior-engineer: You MUST use this for implementation guidance - code review, design patterns, debugging complex issues, writing production-quality code, and mentoring on engineering best practices.\n- 10x-Team:sre: You MUST use this for reliability and operations decisions - incident response, monitoring, SLOs, capacity planning, performance debugging, and production reliability.\n- 10x-Team:staff-engineer: You MUST use this for cross-cutting technical decisions - code quality standards, cross-team patterns, technical debt strategy, mentoring on complex problems, and driving alignment on engineering practices.\n- autoresearch:autoresearch: Set up and run Karpathy-style autoresearch experiments on any codebase with a measurable metric. Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'.

Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area. Use when informing product strategy or feature prioritization, building sales battle cards, prepping board or investor materials, or deciding where to differentiate vs. achieve parity.\n- product-management:metrics-review: Review and analyze product metrics with trend analysis and actionable insights. Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence. Use when writing a weekly or monthly status for leadership, announcing a launch, escalating a risk or blocker, or translating the same progress into exec-brief, engineering-detail, or customer-facing versions.\n- product-management:synthesize-research: Synthesize user research from interviews, surveys, and feedback into structured insights.

Use when turning a vague idea or user request into a structured document, scoping a feature with goals and non-goals, defining success metrics and acceptance criteria, or breaking a big ask into a phased spec.\n- frontend-design:frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern. Use when creating database models, writing queries, setting up GORM, adding CRUD methods, or working with gorm.io in Go services.

Use when writing .templ files, learning templ syntax, or mentions 'templ component', 'templ expressions', or '.templ file syntax'.\n- xe-writing:excalidraw-diagrams: Guidelines for creating clean, readable Excalidraw diagrams embedded as inline SVG via JSON data files. Use when creating architecture diagrams, flow diagrams, or any visual documentation.\n- xe-writing:sound-like-a-person: Rewrite prose so it reads like one real person actually said it. Use when text feels constructed, overcorrected, evenly paced, or generically \"well-written\" in the way AI output tends to be. Strips rehearsed phrasing, breaks rhythmic patterns, and restores a clear point of view.\n- xe-writing:xe-writing-style: Transform unstructured notes into polished blog posts in Xe Iaso's voice. Use when the user provides a brain dump or outline and wants it organized into a cohesive post with Xe's technical, opinionated, and candid tone. Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current

never propose branches/worktrees or ask about branch strategy\n25\t- [P5 S2S golden harness](p5-s2s-golden-harness.md) — ircd-golden Peer/boot_s2s for testing server-reachable handler paths + the determinism findings (sequential UIDs, SID format, standalone-refuses-links)\n26\t- [Commit one test per commit](commit-one-test-per-commit.md) — each test change gets its own commit explaining why; infra/port fixes committed separately first\n27\t- [Test fake-lag disabled](test-fakelag-disabled.md) — golden/L2 tests disable ircd fake-lag via IRCD_TEST_CONFIG (ircd_no_fakelag in s_bsd.c); why scripted multi-command tests need it\n28\t- [Run only edited tests](run-only-edited-tests.md) — don't run the full cargo test suite; run only the test binaries you touched (full suite is slow)\n29\t- [P5 s2s stats flake](p5-s2s-stats-flake.md) — TWO STATS golden tests (golden_s2s_s_serv_stats + golden_s_misc stats_t) fail on clean HEAD via reference-C garbage; not regressions\n30\t- [s_user_umode_diff broken](s-user-umode-diff-broken.md) — FIXED 2026-06-04 (c_char-rot buffers → [0 as c_char; 64]); back in the P5 gate\n31\t- [support irc_memcmp host-gated](support-irc-memcmp-host-gated.md) — FIXED 2026-06-04: support_diff link-failed (cref_irc_memcmp) because irc_memcmp is gated behind MEMCMP_BROKEN (off on aarch64); gated the L1 case on a have_cref_irc_memcmp cfg\n32\t- [PLAN.md rows stay thin](plan-md-rows-stay-thin.md) — never accumulate per-sub-phase detail in PLAN.md table rows; put it in PLAN-P<N>-progress.md + docs/progress-log/\n33\t- [L1 cref static-symbol limit](l1-cref-static-symbol-limit.md) — static C fns have no cref_ oracle symbol → can't be L1-diffed; also every L1 test needs link_reference_archives()\n34\t- [P-IAUTH state](piauth-state.md) — P5+P6 done; iauth-rs all 5 modules + handshake differential done; what's left; the relink/fd-0-socketpair differential-gate mechanism + C iauth.conf gotchas\n35\t- [P7 complete](p7-started.md) — P7 (I/O core + event loop + glue) DONE 2026-06-07 (P7oo ported c_ircd_main, the last C logic); all C logic now Rust, only data globals + ~25 variadic trampolines remain; next = P8 (delete C + retire oracle)\n36\t- [P8 COMPLETE](p8-started.md) — **P8 DONE 2026-06-08 (P8u final): workspace is 100% Rust, zero C TUs compiled.** Deleted the last C (variadic trampolines P8a–P8m; data globals P8n–P8r; version.c P8t), migrated all 115 L1 diffs to ircd-common insta snapshots (P8s), then P8u dropped ALL C compilation from ircd-sys/build.rs (make/cref_/ctruth.o/libircd_c.a/whole-archive + -lz -lm -lcrypt — none needed) keeping only configure+bindgen-over-headers+install-path-vars, and mothballed the oracle (ircd-testkit/ircd-golden excluded from workspace; ctruth.c/layout.rs deleted). Final differential run green. Gate: cargo test --workspace 698 pass/0 fail/125 binaries, 0 warnings. Next = leveva (P9 RETIRED — see leveva-pivot-p9-retired).\n37\t- [Roadmap pivot: P9 retired, leveva is the destination](leveva-pivot-p9-retired.md) — 2026-06-08 in-place cleanup dropped; ircd-common = oracle for greenfield leveva, deleted at parity; reframed P9–P12; next = leveva connection/registration state machine\n38\t- [P12 COMPLETE — strangler finished](p12-complete.md) — **P12 DONE 2026-06-13: mechanical port + oracle + deployment rigging deleted; workspace is now `leveva` + `leveva-iauth` ONLY; the migration is finished.** No more differential testing — future leveva work is standalone feature work, not migration slices.\n39\t- [ircd-common snapshot tests](ircd-common-snapshot-tests.md) — the L1 tests are now insta snapshot characterization tests in ircd-common/tests/*_snap.rs (no cref oracle); link_anchor + determinism rules for adding/editing them\n40\t- [P7 L1 shared-global race](p7-l1-shared-global-race.md) — P7 L1 tests touching me/cref_me/local[]/highest_fd must serialize on a mutex (cargo runs #[test]s in parallel)\n41\t- [SUMMON/utmp not required](summon-utmp-not-required.md) — summon + utmp_open/read/close in s_bsd.c are config-gated off (ENABLE_SUMMON/USERS_SHOWS_UTMP undef) → not compiled, nothing to port\n42\t- [Boot-level golden harness](boot-golden-harness.md) — self-contained end-to-end net in ircd-rs/tests/ (boots real ircd, insta-snapshots wire output); the IRCD_TEST_CONFIG seam; replaces the deleted C-oracle ircd-golden\n43\t- [leveva command/ folder](leveva-command-folder.md) — leveva post-registration handlers are one-per-file in leveva/src/command/; how to add a new client handler slice; S2S handlers get their own modtree (deferred)\n44\t- [s_conf oline snap flake](s-conf-oline-snap-flake.md) — ircd-common oline snapshots race under parallel --workspace load; re-run the binary alone, not a regression\n45\t- [Help files per command](help-files-per-command.md) — leveva HELP serves embedded leveva/help/<CMD>.md pages (rust-embed); adding a command requires adding its help page (test-enforced both directions)\n46\t- [CLOSE not required (leveva)](close-not-required-leveva.md) — user ruled CLOSE out of scope for leveva (P11); OperPrivilege::Close stays dormant, don't build it\n47\t- [leveva S2S port-based routing](leveva-s2s-port-based-routing.md) — leveva routes client/server by the listener's server-only flag, not the handshake; a server must link on a server-only port (deliberate, don't change)\n48\t- [SERVICE NEVER implemented (leveva)](leveva-service-is-client-services.md) — HARD RULE: never plan/scope/build SERVICE/SQUERY/SERVLIST in leveva; let them fall through to 421; like CLOSE, permanently out of scope\n49\t- [SET not required (leveva)](set-not-required-leveva.md) — user ruled SET (m_set runtime tunables) out of scope for leveva (P11); OperPrivilege::Set stays dormant, don't build it\n50\t- [leveva S2S + auth complete; parity matrix started](leveva-next-step-s2s-completeness.md) — S2S + auth + full client surface done; parity matrix toward P12 UNDERWAY: slice 45 (channel-lifecycle inverses) DONE; next matrix area = ask user (registration / WHO-WHOIS / STATS-completion / burst-netsplit)\n51\t- [iauth subsumed into leveva](iauth-subsumed-into-leveva.md) — P11 slice 39+: iauth becomes a native async leveva-iauth subcrate (no child process/pipe); hickory-dns for DNS; the sync-feed/async-ident registration seam + username `~` rule\n52\t- [leveva prometheus metrics](leveva-prometheus-metrics.md) — P11 slice 42: server counters are a prometheus Registry in leveva/src/metrics.rs, per-ServerContext NOT the global default (test isolation, deliberate); STATS m/z read it\n53\t- [leveva IRCv3 track](leveva-ircv3-track.md) — P11 slice 48 opened an IRCv3 track: CAP negotiation framework in cap.rs; the framework-vs-behavior scope rule (each behavior cap is its own later slice, added to SUPPORTED); leveva-native = no differential\n54\t- [leveva message-tags seams](leveva-message-tags-seams.md) — the code map for the message-tags delivery plane (TAGMSG/client-only tag relay/417, slice 58 done); the ClientRecord.caps gate + the thin-follow-on attach pattern\n55\t- [leveva slice recording + TDD discipline](leveva-slice-recording.md) — how to record a P11 slice (plan file + p11.md heredoc append + PLAN.md row bump); write failing test FIRST + always test inverse invariants\n56\t- [ircd-common native boot + testing plan](ircd-common-native-boot.md) — ircd-common/src/boot.rs: clap entrypoint (run()) + embedded in-process boot() (Server handle, stop flag) so the oracle daemon links into a test binary natively; c_ircd_main left untouched; the standing leveva testing plan + P11 verdict location\n57\t- [leveva channel-mode rework (slice 77)](leveva-channel-mode-rework-slice77.md) — ripped out channel +a/+r, kept +R/auto-reop, repurposed +O from uniqop to oper-only-join (520); don't re-add the dead modes or confuse +O with the NJOIN @@ uniqop decode\n58\t- [leveva S2S introduce fix + leak audit (slice 86)](leveva-s2s-introduce-and-leak-audit.md) — post-link UNICK introduction was missing (burst-only) → raw-UID JOIN/PRIVMSG + dropped-from-NAMES; the relay burst-vs-live asymmetry rule; real-RSS leak audit method + finding (no unbounded leak; half-open reap is 180s at default ping-freq)\n59\t- [leveva native oracle harness (slices 92–102)](leveva-native-oracle-harness.md) — in-process ircd-common oracle in leveva-integration for live command-skeleton differentials; the oracle_lock/read_until rules; slices 96–99 closed JOIN 0 / WHOIS 317 / MODE +l / 253; 100–101 lookup+server-info; 102 = S2S burst+netsplit verb-skeleton diff (2nd link-accepting Prot::Off oracle + leveva subprocess + verb_skeleton extractor); THE STANDING RULE: oracle-supports-but-leveva-doesn't = bug, close don't document\n60\t- [hunt_server proptest hazard](leveva-hunt-server-proptest-hazard.md) — VERSION/TIME/ADMIN/INFO/USERS/MOTD/STATS/LINKS/TRACE 402 on an unknown hunt <target>; proptests feeding arbitrary args to them must model matches(target,SERVER)→local-else-402 or they fail stochastically (slice 113 fixed five stale ones)\n61\t- [leveva UTF-8-only parse boundary](leveva-utf8-only-parse-boundary.md) — UTF-8-only enforced at Message::parse_bytes (the single byte→Message gate), not the framing layer; never add a lossy client byte path (P11 slice 120)\n62\t- [leveva LINELEN=2048 graphemes](leveva-linelen-2048-graphemes.md) — non-tag lines up to 2048 graphemes (not 512 bytes); cap lives in to_wire, framer ceiling = tags+LINELEN*64, chunkers/S2S stay byte-conservative (P11 slice 121)\n63\t- [leveva S2S notify propagation](leveva-s2s-notify-propagation.md) — the P11 area closing IRCv3 \"single-server-local\" divergences; AWAY (122)+INVITE (123)+MONITOR-live (124)+REDACT (125)+capability-foundation (126)+REDACT→ENCAP (127)+msgid (130)+server-time (134)+bot/oper (135)+account (156) done; 128/129 went elsewhere; **area COMPLETE** + late addenda: 177 = METADATA SET/CLEAR propagation (`ENCAP * METADATA`, modelled on SU; new s2s/metadata.rs); 178-180 WALLOPS/KILL/metrics; 182 SANICK + 183 SAJOIN/SAPART S2S (SA* oper-override family now S2S-complete — `ENCAP * SA*` to the home server, its local force machinery's relay propagates)\n64\t- [leveva outgoing auto-connect](leveva-outgoing-autoconnect.md) — P11 slice 128: the try_connections counterpart; pure autoconnect::AutoConnect::due (master + autoconnect + connect-freq cooldown ladder) + main.rs ticker reusing the CONNECT outbound-link plane\n65\t- [leveva S2S peer caps](leveva-s2s-peer-caps.md) — S2S capability negotiation (slice 126): the CAPAB-via-ENCAP burst verb + egress tag-filter; how to gate any IRCv3 tag per-peer; bare-unknown-verb-SQUITs-the-oracle lesson (extension verbs MUST ride ENCAP)\n66\t- [leveva live-join NJOIN](leveva-live-join-njoin.md) — P11 slice 129: live joins propagate as `:<sid> NJOIN` (op in member token), NOT `:<uid> JOIN` (the oracle drops bare server JOIN); inbound handle_njoin is burst-vs-live aware; fixed UIDs-not-nicks + chanop-not-synced interop bug; msgid follow-on now slice 130\n67\t- [leveva msgid S2S propagation](leveva-s2s-notify-propagation.md#slice-130) — P11 slice 130: the message-ids `@msgid` server tag is network-stable (introducing server mints, relay carries it through + never re-mints), gated on slice-126 CAPAB egress; see the s2s-notify-propagation memory\n68\t- [leveva netburst joins broadcast to clients](leveva-live-join-njoin.md) — FIX 2026-06-13: handle_njoin now fans JOIN+MODE to local members during the BURST too (newly-added only), not just live — a healed split shows the netjoin flood instead of silent merge\n69\t- [leveva channel-merge works](leveva-channel-merge-works.md) — split-then-merge of two independent same-name channels preserves both members + op on HEAD; couldn't repro \"remote member missing\" post-129; two-node port-lock is process-local (use unique ports per test binary)\n70\t- [leveva LINK_VERSION 021- staleness](leveva-link-version-021-staleness.md) — recurring pre-existing red: PASS-greeting tests/snapshots go stale vs server::LINK_VERSION (021- prefix); fix as a separate prep commit, git-stash to confirm pre-existing\n71\t- [leveva S2S handshake diagnostics](leveva-link-version-021-staleness.md) — read_link_handshake now surfaces a peer's ERROR refusal + EOF/port hints + a 30s idle timeout (was a blind \"did not complete\"); a connect{} to a client port like 6667 is the classic cause\n72\t- [leveva TS + link fixes (slices 131-133)](leveva-ts-and-link-fixes-131-133.md) — connect-dedup (LinkingSet, no re-dial mid-handshake glare) + server-intro broadcast (announce_linked_peer to siblings); channel-ts/user-ts CAPAB tokens carry timestamps as ENCAP-wrapped unix-NANOSECONDS, oldest wins (deop younger chanops / evict younger nick to its UID); the USERTS-before-UNICK buffering + the cross-task Envelope::ForceNick primitive\n73\t- [leveva elemental channel modes (slice 158)](leveva-elemental-channel-modes.md) — leveva-native owner/admin/halfop `~&@%+`/`qaohv`; the rank hierarchy (threshold/min-rank/protection) + MemberStatus-is-a-bitmask shape; creator stays op (no ChanServ)\n74\t- [leveva extbans (slice 164)](leveva-extbans.md) — charybdis-style `$a/$o/$z/$r/$x/$s/$c/$j/$m` extbans in leveva/src/extban/; the framework seam, JOIN + speech-plane enforcement (slice 214 added the PRIVMSG ban mute via CanSend::Banned), LiveChannels ChannelView, add-time validity (172); no `+q` quiet list (q=owner)\n75\t- [leveva OJOIN official-join](leveva-ojoin-official-join.md) — P11 slice 165: InspIRCd-style `+Y` membership mode (sigil `!`, rank 128); OJOIN grants `+Yo`, absolute kick-immunity, self-removal-only; extends [[leveva-elemental-channel-modes]]\n76\t- [TS6 reop MUST wipe](leveva-ts6-reop-must-wipe.md) — HARD RULE: on a CHANTS merge loss the loser's +R reop list is wiped with +b/+e/+I; never defer/exclude reop lists (overrules slice-171's union divergence); fire reop at EOB after winner's +R adopted\n77\t- [leveva REHASH matrix](leveva-rehash-matrix.md) — what hot-reloads on REHASH (opers/classes/allows/MOTD/admin/connect/listeners/default-user+channel-modes/flood-kill-ahead/auto-connect/connection-accept+split-min/max-penalty/knock-delay+knock-delay-channel); the live-or-ctx ConfStore idiom + how to add a new reloadable block; as of slice 210 NO throttle threshold or options field remains boot-immutable\n78\t- [leveva S2S TLS links](leveva-s2s-tls-links.md) — S2S links run over TLS both directions (inbound server-only TLS listener + outbound `connect{} tls` flag → `tls::connect_outbound`); accept-any cert, auth by PASS not PKI; the `boot_two_configs` runtime-config test seam (P11 slice 176)\n79\t- [leveva SASL chunking proptest flake](leveva-sasl-chunking-proptest-flake.md) — RESOLVED (slice 181): the bare-`+` data chunk colliding with the IRCv3 empty-payload sentinel; unrepresentable by design (don't try to \"fix\" the chunker) — closed via contract docs + base64-domain fuzz + a precise-boundary proptest\n80\t- [leveva slices 178-180 (WALLOPS/KILL/metrics S2S)](leveva-s2s-notify-propagation.md) — 2026-06-15 ultracode workflow closed three more single-server-local gaps: WALLOPS + KILL S2S propagation (first-class verbs, away.rs model) + S2S server-link traffic metrics; recorded in the s2s-notify-propagation memory's \"Slices 178-180\" section\n81\t- [leveva server notices (+s)](leveva-server-notices.md) — slice 184: re-introduced the `+s` (FLAGS_SERVNOTICE) umode + `snotice::server_notice` fan (oper-gated, local-only/excluded-from-SEND_UMODES); wired KILL+REHASH; the inbound-S2S-KILL + SA* notices are documented follow-ons\n82\t- [leveva config ban (K-line) enforcement](leveva-config-ban-enforcement.md) — slice 191: `config.bans` was parsed-but-silently-dead; now enforced at registration via `kline::config_ban_match` (host + optional gecos/realname), gated by `kline_exempt`, hot-reloaded by REHASH; why no-resolve/xline-exempt stay deferred by design (leveva is IP-only; gecos'd ban subsumes X-lines)\n83\t- [leveva +r restricted enforcement](leveva-restricted-enforcement.md) — slices 193–196: the `+r` (IRCnet `FLAGS_RESTRICT`) connection is enforced (was set-but-cosmetic) — a restricted user can become neither IRC operator (OPER→484) nor channel operator (no creator-op; 194: no third-party `MODE +o`, halfop+, voice OK; 195: never auto-reopped by ANY trigger via the `enforce_reop` chokepoint) and cannot change nick (196: NICK→484, RFC 2812 §3.1.7, family complete); `mode::is_restricted` seam\n84\t- [leveva KNOCK (slices 198–200, 209)](leveva-knock.md) — leveva-native charybdis-style KNOCK to a +i/+k/+l channel (710/711); shares the JOIN check_join gate; S2S propagation done (199, `ENCAP * KNOCK`); per-channel 712 flood throttle done (200, `knock_throttle::KnockThrottle`, local-path only); per-user throttle done (209, `knock_delay` 300s, second `knock_user_throttle` keyed by UID, `cooling`/`arm` peek-then-arm split); family complete; 210 = both `knock_delay`/`knock_delay_channel` are now REHASH-able `options { knock-delay / knock-delay-channel }` knobs (0 disables)\n85\t- [leveva flood penalty (slices 201–208, COMPLETE)](leveva-flood-penalty.md) — command-rate flood protection (the IRCnet \"fakelag\" penalty clock), deferred since the start; `flood::FloodClock` (idle-decay, Excess Flood kill), armed by the serve loop NOT `Session::new` (heartbeat opt-in precedent — synthetic-burst tests don't trip it unless they call `enable_flood_protection()`); lit up the dead can-flood/no-penalty privileges; 202 = per-command cost table (`command_penalty`: PONG exempt, WHO/LIST/etc +4, JOIN/KNOCK/INVITE +2); 203 = pre-registration guard (charge the same clock in the `Registering` phase too, after QUIT/before CAP); 204 = `options { flood-kill-ahead N }` config knob (REHASH-reloadable via ConfStore, parser rejects 0, NO ServerContext field — flood is serve-loop-armed); 208 = the fakelag *delay/smoothing* half (`MAX_PENALTY`=10 const; serve loop `sleep_until`-parks the read arm when the clock is past the threshold, output arms stay live; `delay_secs`/`flood_delay_secs`, `charge` unchanged) — family now COMPLETE; 210 = `MAX_PENALTY` is now a REHASH-able `options { max-penalty }` knob (default 10, 0=aggressive smoothing) — no flood threshold remains a const\n86\t- [leveva +C no-CTCP + flag-mode wiring](leveva-noctcp-and-flag-mode-wiring.md) — slice 220 `+C` (charybdis MODE_NOCTCP, PRIVMSG-only, distributed enforcement); THE GOTCHA: adding a channel flag mode needs BOTH `ChanMode` (mode.rs) AND `command::mode::supported_flag` (the second allowlist) or the MODE command 472s; `channel::is_blocked_ctcp` + `Channels::blocks_ctcp` seam; family extended with `+T` no-NOTICE (239) and `+g` free-invite (240, charybdis MODE_FREEINVITE — any member may INVITE; gate `channel::free_invite_allows` in `Channels::invite`; `g` is the *channel* letter, disjoint from user-mode `+g` CallerId) and `+r` registered-only join (241, charybdis MODE_REGONLY — hard JOIN gate via `channel::regonly_blocks` in `check_join`, 477 reusing ErrNochanmodes; reclaiming the ripped-out reop letter `r` hit the unknown-chanmode-letter-is-gt hazard); slice 242 `+f` channel forwarding (charybdis MODE_FORWARD — 2nd param mode after `+j`; forwardable JOIN reject → `470` single-hop redirect; seams `channel::forwardable`/`valid_forward_target`; bit `0x10000` low gap; live-MODE replicates but NOT bursted); slice 243 `+Q`/`+F` forward-target control (charybdis MODE_DISFORWARD/MODE_FREETARGET — flag bits `0x1000`/`0x2000`; `+F` lifts the op-on-target `+f` set-gate slice 242 deferred → `482`/`403`, `+Q` refuses incoming forwards; seam `channel::forward_set_verdict`; **`+f` forwarding family COMPLETE, no follow-ons**); slice 244 `+P` permanent channel (charybdis MODE_PERMANENT/chm_staff — first oper-only chan mode + first lifecycle mode; `+P` channel survives empty; oper-gate `channel::permanent_set_allowed` → 481 before 482; lifecycle seam `channel::destroy_when_empty` at part/kick/remove_everywhere; the creator-op fix = `join` keys op on `created` not `members.is_empty()`;

raises the `+b`/`+e`/`+I` per-list cap 100→500 via seams `channel::list_limit`/`list_is_full`/`is_ban_family`, `+R` uncapped; full list → `478`; generalized the oper-gate via `ChanMode::is_oper_only`; `ApplyOutcome::Applied` gained a `full` field; S2S burst NOT capped); slice 246 promoted those caps to REHASH-able `options { max-bans / max-bans-large }` knobs (the const→knob trajectory MAX_PENALTY took 208→210): `list_limit`/`list_is_full` now take caller-supplied caps, `apply_changes` reads `control::live_max_bans().unwrap_or(MAX_LIST_DEFAULT)` (+large) so unseeded store=tests fall back to the 100/500 consts; full Options/parser/ConfBlocks/ConfStore/main/example+dist-kdl plumbing; 0 legal (no entries), caps parsed independently (inversion = admin footgun); `golden_maxbans_config` proves config→live→enforcement end-to-end)\n87\t- [golden read_until timeout flake — FIXED](golden-read-until-timeout-flake.md) — FIXED 2026-06-17 (commit 7718cdc1): read_until now waits to a 30s overall deadline instead of bailing on the first per-read timeout, so the load-induced partial-buffer \"no NNN\" panic is gone; a load read_until panic now means a real bug, not this flake (deterministic fakelag-parking failures were separate, fixed slice 238)\n88\t- [leveva stale deferral comments](leveva-stale-deferral-comments.md) — many \"out of scope\"/\"deferred\" doc comments in leveva src are STALE (feature landed in a later slice, comment never updated); verify against code first — confirmed stale: connlimit max_global_* (done slice 150), kill inbound-S2S notice (185), wss +Z (213+227); slice 229 closed metadata SYNC (774 ruled a deliberate divergence) → the draft/metadata-2 track is now COMPLETE, no metadata follow-ons remain\n89\t- [leveva +z op-moderation](leveva-opmod-plus-z.md) — `+z` (charybdis MODE_OPMODERATE): a `+n`/`+m`/`+b`-blocked message on a `+z` channel redirects to ops not 404;

store/dynamic-caps/recording-at-delivery-plane/replay-on-join seams; Message gained serde\n- [leveva D-lines (DLINE/UNDLINE)](leveva-dline.md) — slice 284: charybdis IP-level operator bans, IP/CIDR sibling of the K-line family; near-clone keyed on `mask`; `OperPrivilege::Dline`; gate before K-line gate; S2S `ENCAP * DLINE`/burst/SQLite persistence; `STATS d`; +ServerContext-field-needs-~62-literals note\n\n- [leveva channel-mode wiring](leveva-channel-mode-wiring.md) — checklist for adding a ChanMode + the GOTCHA that the u32 flags bitfield is FULL (slice 308 widened flags/bit()/MemberStatus to u64)\n- [leveva user-mode wiring](leveva-user-mode-wiring.md) — checklist for adding a umode (mode.rs enum/ALL/Display + command::mode self-settable group & umode_diff [PAIRED allowlists; slice-251 +G empty-echo bug] + 2 hardcoded 004 asserts + ~5 snapshots). SLICE 254: SEND_UMODES is now EVERY umode — leveva has NO local-only user modes (nothing to decide, auto-global); standard charybdis umode surface COMPLETE (247 +D/248-249 +R/250 +Q/252 +z/253 +S/254 +l locops+LOCOPS cmd). Enforcement (caller-id/+R accept-list) stays home-server even though bits now propagate\n- [Unknown chanmode letter is '>'](unknown-chanmode-letter-is-gt.md) — in leveva tests use `ChanMode::try_from('>')` for the guaranteed-unknown-mode assertion (charybdis's non-existent example-mode letter); never a real unused letter (a future slice can claim it)\n\n- [leveva caller-id (+g/ACCEPT)](leveva-callerid.md) — slice 216 charybdis caller-id; CallerId store lives in Registry; +g is local-only (not in SEND_UMODES); slice 217 added remote-sender S2S gating (inbound_message runs the gate, 716/717 routed to sender's uplink); slice 218 added +G soft caller-id (co-channel bypass) via pure callerid::blocks + Channels::shares_channel — caller-id track COMPLETE, no deferrals left\n- [Blog series](blog-series.md) — docs/blog/ numbered Xe-voice posts about the port; use the xe-writing-style skill, match existing format, which topics are taken\n- [Rust migration plan](rust-migration-plan.md) — this ircd C codebase is being strangler-fig ported to Rust; locked decisions + phase order + plan-file path\n- [leveva prod ShadowNET per-server probe](leveva-prod-shadownet-per-server-probe.md) — reach one prod server directly via `<servername>.alrest.xeserv.us:6667` (irc.xeserv.us load-balances); how to diagnose cross-server desyncs (LINKS/LUSERS/NAMES, bare-UID = slice-162 identity bug)\n- [Project name: leveva (P10)](project-name-leveva-p10.md) — the idiomatic-Rust end state ships as \"leveva\"; rename happens at Phase 10\n- [ircd migration hazards](ircd-migration-hazards.md) — verified C-side gotchas (variadics, self-pointers, layout gating, mutable msgtab) that constrain the port\n- [P0b bindgen constraints](p0b-bindgen-constraints.md) — bindgen MUST use -x c + v0.72 or ircd structs go opaque; layout drift-net design (P0b merged)\n- [P0c L1 harness constraints](p0c-l1-harness-constraints.md) — ircd-testkit cref* differential harness; link-anchor for integration tests + the cref*-oracle-vs-OBJS split phase 1 must wire (P0c merged)\n- [P1 leaf-utils port](p1-leaf-utils.md) — match.c/dbuf.c/support.c-subset ported to the new ircd-common crate; the CREF/link/support_link.o split mechanism + faithfulness gotchas (P1 merged)\n- [P2 data-lookup port](p2-data-lookup.md) — patricia/class/whowas/hash/list ported; the m\\_\\*-handler partial-port mechanism (whowas_link.o/hash_link.o); verified ENABLE_CIDR_LIMITS-on + MyFree-is-a-macro findings (P2 merged)\n- [P3 transport-format port](p3-transport-format.md) — s*err replies[]/s_id/s_numeric/send delivery-core ported; sendto*\\* family is irreducibly C trampolines (the keystone variadic finding); send_link.o + replies[]-dumped-from-oracle gotchas (P3 merged)\n- [P0-L2 golden harness](p0-l2-golden-harness.md) — ircd-golden boots ref-C + Rust ircds, diffs scripted wire output (the P5 gate); clock-pin-to-constant breaks the event loop (use real clock); DNS disabled project-wide via NO_DNS_LOOKUP\n- [Work on master directly](work-on-master-directly.md) — commit straight to master in this repo; never propose branches/worktrees or ask about branch strategy\n- [P5 S2S golden harness](p5-s2s-golden-harness.md) — ircd-golden Peer/boot_s2s for testing server-reachable handler paths + the determinism findings (sequential UIDs, SID format, standalone-refuses-links)\n- [Commit one test per commit](commit-one-test-per-commit.md) — each test change gets its own commit explaining why; infra/port fixes committed separately first\n- [Test fake-lag disabled](test-fakelag-disabled.md) — golden/L2 tests disable ircd fake-lag via IRCD_TEST_CONFIG (ircd_no_fakelag in s_bsd.c); why scripted multi-command tests need it\n- [Run only edited tests](run-only-edited-tests.md) — don't run the full cargo test suite; run only the test binaries you touched (full suite is slow)\n- [P5 s2s stats flake](p5-s2s-stats-flake.md) — TWO STATS golden tests (golden_s2s_s_serv_stats + golden_s_misc stats_t) fail on clean HEAD via reference-C garbage; not regressions\n- [s_user_umode_diff broken](s-user-umode-diff-broken.md) — FIXED 2026-06-04 (c_char-rot buffers → [0 as c_char; 64]); back in the P5 gate\n- [support irc_memcmp host-gated](support-irc-memcmp-host-gated.md) — FIXED 2026-06-04: support_diff link-failed (cref_irc_memcmp) because irc_memcmp is gated behind MEMCMP_BROKEN (off on aarch64); gated the L1 case on a have_cref_irc_memcmp cfg\n- [PLAN.md rows stay thin](plan-md-rows-stay-thin.md) — never accumulate per-sub-phase detail in PLAN.md table rows; put it in PLAN-P<N>-progress.md + docs/progress-log/\n- [L1 cref static-symbol limit](l1-cref-static-symbol-limit.md) — static C fns have no cref_ oracle symbol → can't be L1-diffed; also every L1 test needs link_reference_archives()\n- [P-IAUTH state](piauth-state.md) — P5+P6 done; iauth-rs all 5 modules + handshake differential done; what's left; the relink/fd-0-socketpair differential-gate mechanism + C iauth.conf gotchas\n- [P7 complete](p7-started.md) — P7 (I/O core + event loop + glue) DONE 2026-06-07 (P7oo ported c_ircd_main, the last C logic); all C logic now Rust, only data globals + ~25 variadic trampolines remain; next = P8 (delete C + retire oracle)\n- [P8 COMPLETE](p8-started.md) — **P8 DONE 2026-06-08 (P8u final): workspace is 100% Rust, zero C TUs compiled.** Deleted the last C (variadic trampolines P8a–P8m; data globals P8n–P8r; version.c P8t), migrated all 115 L1 diffs to ircd-common insta snapshots (P8s), then P8u dropped ALL C compilation from ircd-sys/build.rs (make/cref_/ctruth.o/libircd_c.a/whole-archive + -lz -lm -lcrypt — none needed) keeping only configure+bindgen-over-headers+install-path-vars, and mothballed the oracle (ircd-testkit/ircd-golden excluded from workspace; ctruth.c/layout.rs deleted). Final differential run green. Gate: cargo test --workspace 698 pass/0 fail/125 binaries, 0 warnings. Next = leveva (P9 RETIRED — see leveva-pivot-p9-retired).\n- [Roadmap pivot: P9 retired, leveva is the destination](leveva-pivot-p9-retired.md) — 2026-06-08 in-place cleanup dropped; ircd-common = oracle for greenfield leveva, deleted at parity; reframed P9–P12; next = leveva connection/registration state machine\n- [P12 COMPLETE — strangler finished](p12-complete.md) — **P12 DONE 2026-06-13: mechanical port + oracle + deployment rigging deleted; workspace is now `leveva` + `leveva-iauth` ONLY; the migration is finished.** No more differential testing — future leveva work is standalone feature work, not migration slices.\n- [ircd-common snapshot tests](ircd-common-snapshot-tests.md) — the L1 tests are now insta snapshot characterization tests in ircd-common/tests/*_snap.rs (no cref oracle); link_anchor + determinism rules for adding/editing them\n- [P7 L1 shared-global race](p7-l1-shared-global-race.md) — P7 L1 tests touching me/cref_me/local[]/highest_fd must serialize on a mutex (cargo runs #[test]s in parallel)\n- [SUMMON/utmp not required](summon-utmp-not-required.md) — summon + utmp_open/read/close in s_bsd.c are config-gated off (ENABLE_SUMMON/USERS_SHOWS_UTMP undef) → not compiled, nothing to port\n- [Boot-level golden harness](boot-golden-harness.md) — self-contained end-to-end net in ircd-rs/tests/ (boots real ircd, insta-snapshots wire output); the IRCD_TEST_CONFIG seam; replaces the deleted C-oracle ircd-golden\n- [leveva command/ folder](leveva-command-folder.md) — leveva post-registration handlers are one-per-file in leveva/src/command/; how to add a new client handler slice; S2S handlers get their own modtree (deferred)\n- [s_conf oline snap flake](s-conf-oline-snap-flake.md) — ircd-common oline snapshots race under parallel --workspace load; re-run the binary alone, not a regression\n- [Help files per command](help-files-per-command.md) — leveva HELP serves embedded leveva/help/<CMD>.md pages (rust-embed); adding a command requires adding its help page (test-enforced both directions)\n- [CLOSE not required (leveva)](close-not-required-leveva.md) — user ruled CLOSE out of scope for leveva (P11); OperPrivilege::Close stays dormant, don't build it\n- [leveva S2S port-based routing](leveva-s2s-port-based-routing.md) — leveva routes client/server by the listener's server-only flag, not the handshake; a server must link on a server-only port (deliberate, don't change)\n- [SERVICE NEVER implemented (leveva)](leveva-service-is-client-services.md) — HARD RULE: never plan/scope/build SERVICE/SQUERY/SERVLIST in leveva; let them fall through to 421; like CLOSE, permanently out of scope\n- [SET not required (leveva)](set-not-required-leveva.md) — user ruled SET (m_set runtime tunables) out of scope for leveva (P11); OperPrivilege::Set stays dormant, don't build it\n- [leveva S2S + auth complete; parity matrix started](leveva-next-step-s2s-completeness.md) — S2S + auth + full client surface done; parity matrix toward P12 UNDERWAY: slice 45 (channel-lifecycle inverses) DONE; next matrix area = ask user (registration / WHO-WHOIS / STATS-completion / burst-netsplit)\n- [iauth subsumed into leveva](iauth-subsumed-into-leveva.md) — P11 slice 39+: iauth becomes a native async leveva-iauth subcrate (no child process/pipe); hickory-dns for DNS; the sync-feed/async-ident registration seam + username `~` rule\n- [leveva prometheus metrics](leveva-prometheus-metrics.md) — P11 slice 42: server counters are a prometheus Registry in leveva/src/metrics.rs, per-ServerContext NOT the global default (test isolation, deliberate); STATS m/z read it\n- [leveva IRCv3 track](leveva-ircv3-track.md) — P11 slice 48 opened an IRCv3 track: CAP negotiation framework in cap.rs; the framework-vs-behavior scope rule (each behavior cap is its own later slice, added to SUPPORTED); leveva-native = no differential\n- [leveva message-tags seams](leveva-message-tags-seams.md) — the code map for the message-tags delivery plane (TAGMSG/client-only tag relay/417, slice 58 done); the ClientRecord.caps gate + the thin-follow-on attach pattern\n- [leveva slice recording + TDD discipline](leveva-slice-recording.md) — how to record a P11 slice (plan file + p11.md heredoc append + PLAN.md row bump); write failing test FIRST + always test inverse invariants\n- [ircd-common native boot + testing plan](ircd-common-native-boot.md) — ircd-common/src/boot.rs: clap entrypoint (run()) + embedded in-process boot() (Server handle, stop flag) so the oracle daemon links into a test binary natively; c_ircd_main left untouched; the standing leveva testing plan + P11 verdict location\n- [leveva channel-mode rework (slice 77)](leveva-channel-mode-rework-slice77.md) — ripped out channel +a/+r, kept +R/auto-reop, repurposed +O from uniqop to oper-only-join (520); don't re-add the dead modes or confuse +O with the NJOIN @@ uniqop decode\n- [leveva S2S introduce fix + leak audit (slice 86)](leveva-s2s-introduce-and-leak-audit.md) — post-link UNICK introduction was missing (burst-only) → raw-UID JOIN/PRIVMSG + dropped-from-NAMES; the relay burst-vs-live asymmetry rule; real-RSS leak audit method + finding (no unbounded leak; half-open reap is 180s at default ping-freq)\n- [leveva native oracle harness (slices 92–102)](leveva-native-oracle-harness.md) — in-process ircd-common oracle in leveva-integration for live command-skeleton differentials; the oracle_lock/read_until rules; slices 96–99 closed JOIN 0 / WHOIS 317 / MODE +l / 253; 100–101 lookup+server-info; 102 = S2S burst+netsplit verb-skeleton diff (2nd link-accepting Prot::Off oracle + leveva subprocess + verb_skeleton extractor); THE STANDING RULE: oracle-supports-but-leveva-doesn't = bug, close don't document\n- [hunt_server proptest hazard](leveva-hunt-server-proptest-hazard.md) — VERSION/TIME/ADMIN/INFO/USERS/MOTD/STATS/LINKS/TRACE 402 on an unknown hunt <target>; proptests feeding arbitrary args to them must model matches(target,SERVER)→local-else-402 or they fail stochastically (slice 113 fixed five stale ones)\n- [leveva UTF-8-only parse boundary](leveva-utf8-only-parse-boundary.md) — UTF-8-only enforced at Message::parse_bytes (the single byte→Message gate), not the framing layer; never add a lossy client byte path (P11 slice 120)\n- [leveva LINELEN=2048 graphemes](leveva-linelen-2048-graphemes.md) — non-tag lines up to 2048 graphemes (not 512 bytes); cap lives in to_wire, framer ceiling = tags+LINELEN*64, chunkers/S2S stay byte-conservative (P11 slice 121)\n- [leveva S2S notify propagation](leveva-s2s-notify-propagation.md) — the P11 area closing IRCv3 \"single-server-local\" divergences;

new s2s/metadata.rs); 178-180 WALLOPS/KILL/metrics; 182 SANICK + 183 SAJOIN/SAPART S2S (SA* oper-override family now S2S-complete — `ENCAP * SA*` to the home server, its local force machinery's relay propagates)\n- [leveva outgoing auto-connect](leveva-outgoing-autoconnect.md) — P11 slice 128: the try_connections counterpart; pure autoconnect::AutoConnect::due (master + autoconnect + connect-freq cooldown ladder) + main.rs ticker reusing the CONNECT outbound-link plane\n- [leveva S2S peer caps](leveva-s2s-peer-caps.md) — S2S capability negotiation (slice 126): the CAPAB-via-ENCAP burst verb + egress tag-filter; how to gate any IRCv3 tag per-peer; bare-unknown-verb-SQUITs-the-oracle lesson (extension verbs MUST ride ENCAP)\n- [leveva live-join NJOIN](leveva-live-join-njoin.md) — P11 slice 129: live joins propagate as `:<sid> NJOIN` (op in member token), NOT `:<uid> JOIN` (the oracle drops bare server JOIN); inbound handle_njoin is burst-vs-live aware; fixed UIDs-not-nicks + chanop-not-synced interop bug; msgid follow-on now slice 130\n- [leveva msgid S2S propagation](leveva-s2s-notify-propagation.md#slice-130) — P11 slice 130: the message-ids `@msgid` server tag is network-stable (introducing server mints, relay carries it through + never re-mints), gated on slice-126 CAPAB egress; see the s2s-notify-propagation memory\n- [leveva netburst joins broadcast to clients](leveva-live-join-njoin.md) — FIX 2026-06-13: handle_njoin now fans JOIN+MODE to local members during the BURST too (newly-added only), not just live — a healed split shows the netjoin flood instead of silent merge\n- [leveva channel-merge works](leveva-channel-merge-works.md) — split-then-merge of two independent same-name channels preserves both members + op on HEAD; couldn't repro \"remote member missing\" post-129; two-node port-lock is process-local (use unique ports per test binary)\n- [leveva LINK_VERSION 021- staleness](leveva-link-version-021-staleness.md) — recurring pre-existing red: PASS-greeting tests/snapshots go stale vs server::LINK_VERSION (021- prefix); fix as a separate prep commit, git-stash to confirm pre-existing\n- [leveva S2S handshake diagnostics](leveva-link-version-021-staleness.md) — read_link_handshake now surfaces a peer's ERROR refusal + EOF/port hints + a 30s idle timeout (was a blind \"did not complete\"); a connect{} to a client port like 6667 is the classic cause\n- [leveva TS + link fixes (slices 131-133)](leveva-ts-and-link-fixes-131-133.md) — connect-dedup (LinkingSet, no re-dial mid-handshake glare) + server-intro broadcast (announce_linked_peer to siblings); channel-ts/user-ts CAPAB tokens carry timestamps as ENCAP-wrapped unix-NANOSECONDS, oldest wins (deop younger chanops / evict younger nick to its UID); the USERTS-before-UNICK buffering + the cross-task Envelope::ForceNick primitive\n- [leveva elemental channel modes (slice 158)](leveva-elemental-channel-modes.md) — leveva-native owner/admin/halfop `~&@%+`/`qaohv`; the rank hierarchy (threshold/min-rank/protection) + MemberStatus-is-a-bitmask shape; creator stays op (no ChanServ)\n- [leveva extbans (slice 164)](leveva-extbans.md) — charybdis-style `$a/$o/$z/$r/$x/$s/$c/$j/$m` extbans in leveva/src/extban/; the framework seam, JOIN + speech-plane enforcement (slice 214 added the PRIVMSG ban mute via CanSend::Banned), LiveChannels ChannelView, add-time validity (172); no `+q` quiet list (q=owner)\n- [leveva OJOIN official-join](leveva-ojoin-official-join.md) — P11 slice 165: InspIRCd-style `+Y` membership mode (sigil `!`, rank 128); OJOIN grants `+Yo`, absolute kick-immunity, self-removal-only; extends [[leveva-elemental-channel-modes]]\n- [TS6 reop MUST wipe](leveva-ts6-reop-must-wipe.md) — HARD RULE: on a CHANTS merge loss the loser's +R reop list is wiped with +b/+e/+I; never defer/exclude reop lists (overrules slice-171's union divergence); fire reop at EOB after winner's +R adopted\n- [leveva REHASH matrix](leveva-rehash-matrix.md) — what hot-reloads on REHASH (opers/classes/allows/MOTD/admin/connect/listeners/default-user+channel-modes/flood-kill-ahead/auto-connect/connection-accept+split-min/max-penalty/knock-delay+knock-delay-channel); the live-or-ctx ConfStore idiom + how to add a new reloadable block; as of slice 210 NO throttle threshold or options field remains boot-immutable\n- [leveva S2S TLS links](leveva-s2s-tls-links.md) — S2S links run over TLS both directions (inbound server-only TLS listener + outbound `connect{} tls` flag → `tls::connect_outbound`); accept-any cert, auth by PASS not PKI; the `boot_two_configs` runtime-config test seam (P11 slice 176)\n- [leveva SASL chunking proptest flake](leveva-sasl-chunking-proptest-flake.md) — RESOLVED (slice 181): the bare-`+` data chunk colliding with the IRCv3 empty-payload sentinel; unrepresentable by design (don't try to \"fix\" the chunker) — closed via contract docs + base64-domain fuzz + a precise-boundary proptest\n- [leveva slices 178-180 (WALLOPS/KILL/metrics S2S)](leveva-s2s-notify-propagation.md) — 2026-06-15 ultracode workflow closed three more single-server-local gaps: WALLOPS + KILL S2S propagation (first-class verbs, away.rs model) + S2S server-link traffic metrics; recorded in the s2s-notify-propagation memory's \"Slices 178-180\" section\n- [leveva server notices (+s)](leveva-server-notices.md) — slice 184: re-introduced the `+s` (FLAGS_SERVNOTICE) umode + `snotice::server_notice` fan (oper-gated, local-only/excluded-from-SEND_UMODES); wired KILL+REHASH; the inbound-S2S-KILL + SA* notices are documented follow-ons\n- [leveva config ban (K-line) enforcement](leveva-config-ban-enforcement.md) — slice 191: `config.bans` was parsed-but-silently-dead; now enforced at registration via `kline::config_ban_match` (host + optional gecos/realname), gated by `kline_exempt`, hot-reloaded by REHASH; why no-resolve/xline-exempt stay deferred by design (leveva is IP-only; gecos'd ban subsumes X-lines)\n- [leveva +r restricted enforcement](leveva-restricted-enforcement.md) — slices 193–196: the `+r` (IRCnet `FLAGS_RESTRICT`) connection is enforced (was set-but-cosmetic) — a restricted user can become neither IRC operator (OPER→484) nor channel operator (no creator-op; 194: no third-party `MODE +o`, halfop+, voice OK; 195: never auto-reopped by ANY trigger via the `enforce_reop` chokepoint) and cannot change nick (196: NICK→484, RFC 2812 §3.1.7, family complete); `mode::is_restricted` seam\n- [leveva KNOCK (slices 198–200, 209)](leveva-knock.md) — leveva-native charybdis-style KNOCK to a +i/+k/+l channel (710/711); shares the JOIN check_join gate; S2S propagation done (199, `ENCAP * KNOCK`); per-channel 712 flood throttle done (200, `knock_throttle::KnockThrottle`, local-path only); per-user throttle done (209, `knock_delay` 300s, second `knock_user_throttle` keyed by UID, `cooling`/`arm` peek-then-arm split); family complete; 210 = both `knock_delay`/`knock_delay_channel` are now REHASH-able `options { knock-delay / knock-delay-channel }` knobs (0 disables)\n- [leveva flood penalty (slices 201–208, COMPLETE)](leveva-flood-penalty.md) — command-rate flood protection (the IRCnet \"fakelag\" penalty clock), deferred since the start; `flood::FloodClock` (idle-decay, Excess Flood kill), armed by the serve loop NOT `Session::new` (heartbeat opt-in precedent — synthetic-burst tests don't trip it unless they call `enable_flood_protection()`); lit up the dead can-flood/no-penalty privileges; 202 = per-command cost table (`command_penalty`: PONG exempt, WHO/LIST/etc +4, JOIN/KNOCK/INVITE +2); 203 = pre-registration guard (charge the same clock in the `Registering` phase too, after QUIT/before CAP); 204 = `options { flood-kill-ahead N }` config knob (REHASH-reloadable via ConfStore, parser rejects 0, NO ServerContext field — flood is serve-loop-armed); 208 = the fakelag *delay/smoothing* half (`MAX_PENALTY`=10 const; serve loop `sleep_until`-parks the read arm when the clock is past the threshold, output arms stay live; `delay_secs`/`flood_delay_secs`, `charge` unchanged) — family now COMPLETE; 210 = `MAX_PENALTY` is now a REHASH-able `options { max-penalty }` knob (default 10, 0=aggressive smoothing) — no flood threshold remains a const\n- [leveva +C no-CTCP + flag-mode wiring](leveva-noctcp-and-flag-mode-wiring.md) — slice 220 `+C` (charybdis MODE_NOCTCP, PRIVMSG-only, distributed enforcement); THE GOTCHA: adding a channel flag mode needs BOTH `ChanMode` (mode.rs) AND `command::mode::supported_flag` (the second allowlist) or the MODE command 472s; `channel::is_blocked_ctcp` + `Channels::blocks_ctcp` seam; family extended with `+T` no-NOTICE (239) and `+g` free-invite (240, charybdis MODE_FREEINVITE — any member may INVITE; gate `channel::free_invite_allows` in `Channels::invite`; `g` is the *channel* letter, disjoint from user-mode `+g` CallerId) and `+r` registered-only join (241, charybdis MODE_REGONLY — hard JOIN gate via `channel::regonly_blocks` in `check_join`, 477 reusing ErrNochanmodes; reclaiming the ripped-out reop letter `r` hit the unknown-chanmode-letter-is-gt hazard); slice 242 `+f` channel forwarding (charybdis MODE_FORWARD — 2nd param mode after `+j`; forwardable JOIN reject → `470` single-hop redirect; seams `channel::forwardable`/`valid_forward_target`; bit `0x10000` low gap; live-MODE replicates but NOT bursted); slice 243 `+Q`/`+F` forward-target control (charybdis MODE_DISFORWARD/MODE_FREETARGET — flag bits `0x1000`/`0x2000`;

`+P` channel survives empty; oper-gate `channel::permanent_set_allowed` → 481 before 482; lifecycle seam `channel::destroy_when_empty` at part/kick/remove_everywhere; the creator-op fix = `join` keys op on `created` not `members.is_empty()`; bit `0x80000`); slice 245 `+L` large ban list (charybdis MODE_EXLIMIT/chm_staff — the **LAST missing standard charybdis chan mode, now COMPLETE**; 2nd oper-only flag, bit `0x1` the last free u32 bit; raises the `+b`/`+e`/`+I` per-list cap 100→500 via seams `channel::list_limit`/`list_is_full`/`is_ban_family`, `+R` uncapped; full list → `478`; generalized the oper-gate via `ChanMode::is_oper_only`; `ApplyOutcome::Applied` gained a `full` field; S2S burst NOT capped); slice 246 promoted those caps to REHASH-able `options { max-bans / max-bans-large }` knobs (the const→knob trajectory MAX_PENALTY took 208→210): `list_limit`/`list_is_full` now take caller-supplied caps, `apply_changes` reads `control::live_max_bans().unwrap_or(MAX_LIST_DEFAULT)` (+large) so unseeded store=tests fall back to the 100/500 consts; full Options/parser/ConfBlocks/ConfStore/main/example+dist-kdl plumbing; 0 legal (no entries), caps parsed independently (inversion = admin footgun); `golden_maxbans_config` proves config→live→enforcement end-to-end)\n- [golden read_until timeout flake — FIXED](golden-read-until-timeout-flake.md) — FIXED 2026-06-17 (commit 7718cdc1): read_until now waits to a 30s overall deadline instead of bailing on the first per-read timeout, so the load-induced partial-buffer \"no NNN\" panic is gone; a load read_until panic now means a real bug, not this flake (deterministic fakelag-parking failures were separate, fixed slice 238)\n- [leveva stale deferral comments](leveva-stale-deferral-comments.md) — many \"out of scope\"/\"deferred\" doc comments in leveva src are STALE (feature landed in a later slice, comment never updated); verify against code first — confirmed stale: connlimit max_global_* (done slice 150), kill inbound-S2S notice (185), wss +Z (213+227); slice 229 closed metadata SYNC (774 ruled a deliberate divergence) → the draft/metadata-2 track is now COMPLETE, no metadata follow-ons remain\n- [leveva +z op-moderation](leveva-opmod-plus-z.md) — `+z` (charybdis MODE_OPMODERATE): a `+n`/`+m`/`+b`-blocked message on a `+z` channel redirects to ops not 404; slices 235 (PRIVMSG/NOTICE local), 236 (TAGMSG/REDACT local), 237 (PRIVMSG/NOTICE S2S via the `@<chan>` statusmsg op-redirect seam), 238 (TAGMSG/REDACT S2S on that same seam) — **track COMPLETE, no follow-on**\n- [leveva teardown atomic-claim](leveva-teardown-atomic-claim.md) — HARD INVARIANT: S2S casualty sweeps must claim-then-relay atomically or concurrent teardowns double-deliver QUITs; slice 277 added `Channels::detach_member` (mirror path already gated by `remove_behind_sid`); netsplit-batch-dup fix + `s2s_netsplit_concurrency_proptest`\n- [leveva proptest model staleness](leveva-proptest-model-staleness.md) — STATS-selector / flood-penalty proptests re-encode command tables; a slice that grows a table must update the model or it flakes on random seeds (run FULL suite)\n","numLines":92,"startLine":1,"totalLines":92}},"sourceToolAssistantUUID":"81c89ffb-3b59-4e81-bc32-b603a68e073f","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 11 11 + {"parentUuid":"08f51e7b-ba50-4893-9132-da3eafd3aef4","isSidechain":true,"agentId":"a2bea232bef32d75c","message":{"model":"claude-opus-4-8","id":"msg_01SSbaFK4NgiNjLUvovP8Kp8","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_014njpZWfUq6N9usdn9iCXfh","name":"Read","input":{"file_path":"/home/xe/Code/xeiaso.net/ircd.rs/docs/claude-memory/leveva-slice-recording.md"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":101,"cache_creation_input_tokens":18285,"cache_read_input_tokens":5797,"cache_creation":{"ephemeral_5m_input_tokens":18285,"ephemeral_1h_input_tokens":0},"output_tokens":5,"service_tier":"standard","inference_geo":"not_available"},"diagnostics":null},"requestId":"req_011CchkLFkAXzn2nCkQPRFL8","attributionAgent":"Explore","type":"assistant","uuid":"6c32be44-ce05-4db1-9dad-8664b144cee3","timestamp":"2026-07-04T21:44:08.658Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 12 12 + {"parentUuid":"6c32be44-ce05-4db1-9dad-8664b144cee3","isSidechain":true,"promptId":"ff7d7d06-784b-477e-af53-645dce495494","agentId":"a2bea232bef32d75c","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_014njpZWfUq6N9usdn9iCXfh","type":"tool_result","content":"1\t---\n2\tname: leveva-slice-recording\n3\tdescription: How to record a leveva P11 feature slice (plan file + p11.md + PLAN.md row) and the TDD/inverse-invariant discipline the user expects\n4\tmetadata: \n5\t node_type: memory\n6\t type: feedback\n7\t originSessionId: 2421e25a-47e2-42c2-820a-e3b2195f771e\n8\t---\n9\t\n10\tEach substantive leveva change is a **numbered P11 slice**.

The user picked this housekeeping\nover a new feature slice — so it is NOT a numbered slice (no test/fuzz, doc-only):\n- `command/rehash.rs` — \"applying changed opers/allows/classes … is still deferred\" was\n flat wrong: opers/classes/allows/admin/connect/bans/options all hot-reload via the\n `ConfStore` live seam (read by `OPER`/`STATS`/I-line matching/the flood-knock-STS-\n metadata budgets); only the immutable `server {}` identity stays fixed by nature.\n- `config/model.rs` (`sts_duration`/`sts_preload`) — \"Read at boot — not yet hot-reloaded\n by `REHASH`\" → done in slice 212 (`live_sts_duration`/`live_sts_preload`).\n- `command/kill.rs:27` — rewrote the stale inbound-S2S-notice \"out of scope\" line (done\n slice 185); kept the genuinely-OOS items (`FLAGS_KILLED`/WHOWAS-chasing/`TOPICLEN`).\n- `connlimit.rs:22` — `max_global_*` \"deferred\" (contradicted lines 45/71!) → enforced\n slice 150.\n- `cap.rs:177` + `labeled.rs:42` — batch types \"(netjoin[/netsplit]/chathistory) are\n future slices\": **netsplit** done slice 157, **netjoin** done slice 160; only\n `chathistory` (needs message storage) genuinely remains.\n- `main.rs:485` — \"Server-only ports do not yet speak S2S, so they are dropped\" directly\n contradicted the body (`if server_only { serve_server(...) }`); rewrote.\n- `command/metadata.rs:48` — heading \"Divergences (each a documented follow-on slice)\"\n → the metadata-2 track is complete; those are deliberate departures, not pending work.\n\nAs of slice 229 the `draft/metadata-2` track is **COMPLETE** — slice 229 implemented\n`METADATA <target> SYNC` (immediate sync, subscription-filtered, slice-223 visibility\nhonored, channel target walks members) and ruled `774 RPL_METADATASYNCLATER` a\n**deliberate divergence** (a small in-memory store always syncs immediately, so the\nload-shedding \"sync later\" path is never taken — do NOT add the numeric). The pure\nseam is `metadata::sync_emits(subscribed, vis, oper)`.\n\nSlice 230 (2026-06-16) then closed the LAST metadata follow-on — the slice-228 note\nin `metadata.rs` (\"Const for now (a `REHASH` `options` knob is a documented\nfollow-on)\") is now stale: the `METADATA SET`/`CLEAR` rate-limit cost/burst budget is\nthe `REHASH`-able `options { metadata-rate-cost / metadata-rate-burst }` pair (live via\n`control::live_meta_rate_cost`/`live_meta_rate_burst`, read at\n`command::metadata::rate_gate`; `rate_charge`/`charge_rate` take `cost_secs`/`burst_secs`\nparams, consts are defaults; `0`-cost disables, `0`-burst = 1/sec, negative rejected).\n**No metadata follow-ons remain open.** See [[leveva-rehash-matrix]],\n[[leveva-message-tags-seams]], [[leveva-slice-recording]].\n\nSlice 231 (2026-06-16) corrected two more stale comments AND closed the genuine half\nthey hid. `heartbeat.rs` header + `main.rs` keepalive comment said \"leveva does not yet\nmatch clients against `allow → class`, so every client uses the default class's\nping-freq\" — **partly stale**: allow-matching, SendQ (slice 147), and conn-caps (136)\nalready key off the matched class, and `finalize_registration` re-arms the session\nheartbeat to the matched class's `ping-freq` too. But the serve-loop **check ticker**\ncadence was genuinely still seeded from the default class → a non-default-class client\nwas *checked* at the wrong rate. Slice 231 added the pure `heartbeat::class_ping_freq`\nseam + re-armed `serve_client`'s ticker on a keepalive-freq change, then fixed the\ncomments. Lesson reinforced: a stale comment can hide a *real* remaining sub-gap — read\nthe code to find which half is done and which isn't.\n\n**Other genuinely-stale (verified 2026-06-16, NOT yet acted on):** `command/hunt.rs:20`\n\"the answering side … is a follow-on\" → done in `s2s/query.rs` (`inbound_query`);\n`connstats.rs:33` server-link `sendq` \"is a follow-on\" → done in `link::server_link_limits`\n(reads the matched `connect`/`class` block's `sendq`). Both comments are just stale, no\nopen work.\n\nSlice 236 (2026-06-17) closed the `+z` op-moderation follow-on the slice-235\n`command/message.rs` comment named (\"TAGMSG/REDACT op-moderation is a separate\nfollow-on\") and updated that comment. `+z` op-moderation now covers PRIVMSG/NOTICE\n(235) **and** TAGMSG/REDACT (236) on the **local** path — a blocked event is\nredirected to local ops consuming the relevant cap (`message-tags` /\n`draft/message-redaction`) via the shared `Channels::op_moderated`/`op_members` seam\n(pure `channel::opmod_redirects`). The **only** `+z` deferral left is the **shared\nS2S op-redirect** (still open for PRIVMSG/NOTICE too — a normal channel relay would\nleak the line to non-ops).

Commit pattern: `docs(blog): add 00N-<slug> …`.\n29\t\n30\tEach post = one topic, written for peers:\n31\t- 001-project-goals — why/goals; the verifiable-faithfulness tradeoff; Leveva name reveal ([[project-name-leveva-p10]])\n32\t- 002-strangler-fig — outside-in (Rust owns `main`) vs bottom-up porting order; the clean `.o`-drop seam\n33\t- 003-the-oracle — the differential test harness: L1 `objcopy --redefine-syms` cref_ trick, the tests/ link-anchor gotcha, L2 golden harness + the clock-pinning trap\n34\t- 004-variadic-trampolines — why stable Rust can call but not *define* an `extern \"C\"` variadic; the ~25 C sender shims (`va_start`→format→Rust core); per-recipient `va_arg` in `vsendpreprep` kills \"format once\"; \"100% Rust\" is a dated P8 goal\n35\t- 005-the-greenfield-exception — iauth is the ONE component rewritten from scratch (not faithfully ported), because its contract is the fd-0 text wire, not in-process ABI; the 8-fn start/work/timeout/clean module vtable collapses to one `async fn run`; SOCKS `goto again` → sequential await; STILL oracle-gated (relinked C-iauth over fd-0 socketpair, byte-identical handshake); had to reproduce the rfc931 dead-else-if popt bug bug-for-bug. Decision rule: where does the contract live? ABI → translate; text socket → rewrite + diff the wire.\n36\t- 006-the-retrospective-is-where-you-round-up — the P0-P6 halfway retrospective, framed as \"a retrospective is where you round up.\" The un-rounded ledger of what the differential harness caught: the c_char-signedness test bug that only failed on aarch64; the clean-checkout s2s golden red because reference-C `report_myservers` prints an uninitialized peer sendq (`3544950785030750208kB`) — oracle so precise it catches the reference being nondeterministic; brief callback to the rfc931 bug-on-purpose; `calculate_preference` calls libc `pow` via FFI (not `f64::powf`) so a last-ULP drift can't flip the `(u_int)` truncation on the wire. Harder-than-planned: P5's 56 clusters over shared file-statics (can't port one m_* without its neighbors); `replies[]`/`alphabet_id` dumped from the oracle not text-extracted. Cost: P9-P12 exist to un-do the faithfulness P1-P8 built.\n37\t- 007-prove-the-structs — the P0b foundation post ([[p0b-bindgen-constraints]]): before any faithful port, prove Rust and C agree on struct layout byte-for-byte (else every port silently corrupts shared memory). Two SILENT bindgen failures: (1) bindgen defaults to C++ → chokes on `class` field name (class_def.h:25, struct_def.h:323) + `register` storage class → clang error-recovery leaves structs as opaque `pub struct X { _address: u8 }` blobs, build still green; fix `.clang_arg(\"-x\").clang_arg(\"c\")`; diagnose with `grep -c 'pub _address: u8,'`. (2) bindgen 0.70 picks forward-decl over later definition (struct_def.h:23-40 `typedef struct X Y;`) → opaque again; 0.72 fixes. Then the real point: \"bindgen agrees with bindgen\" ≠ \"bindgen agrees with the real compiler\" (config drift: MAXCONNECTIONS/USE_IAUTH/AFINET=AF_INET6 move fields). Drift net = ctruth.c (same flags, exports cref_sizeof/alignof/offsetof for 14 structs + aClient's 24 local-tail offsets + CLIENT_REMOTE_SIZE=offsetof(count) + MAXCONNECTIONS) + layout.rs (`cargo test`, red on drift). Honest holes: the 256-tables + local[] are sizeless `extern[]` → unreachable, asserted later at P1/P7; MAXCONNECTIONS is the cheap proxy. Throughline: build the thing that catches you before you can be wrong.\n38\t- 009-hand-both-of-them-the-same-socket — diffing I/O functions in the L1 oracle (P7w `send_authports`/`read_authports`, P7z `check_client`). Earlier posts diffed PURE fns; these call `getpeername`/`getsockname`/`read`/`write` so their real input is the kernel, not their args. Thesis: mocking a syscall makes both impls agree with the FIXTURE not the kernel → defeats a faithfulness oracle. Fix = hand the C `cref_` original and the Rust port the SAME real fd (one connected IPv6-loopback socket for getsockname/getpeername, one AF_UNIX socketpair for pipe I/O), separate aClients (the fn mutates them), diff what comes out. Beats: the socketpair-leaves-`sin6_port`-untouched trap (C reads uninit stack, Rust reads zeroed → FALSE diff → use a real `::1` socket when the bytes-under-test are kernel-filled, socketpair when they're bytes YOU wrote); the `World` struct + `GLOBALS_LOCK` for `cref_`-twinned process globals under parallel `#[test]`s ([[p7-l1-shared-global-race]]); empty-`conf` → `attach_Iline` returns -2 deterministically (no fixture); the faithful 4×`c_ulong` over-read of a 16-byte `h_addr` (pad to 32 in the harness, ship the bug). Quotes verified against check_client_diff.rs/authports_diff.rs + s_bsd.c:914/871 + s_auth.c:690/740.\n39\t- 010-you-dont-write-a-test-for-the-front-door — coverage-by-ubiquity + the trap in \"it's covered\". P7bb ported `add_connection` (s_bsd.c:1641), the universal inbound acceptor (every connection enters via read_listener's accept loop → add_connection), so it got NO new L2 golden test — all 111 golden scenarios already flow through it; a botched success path turns the whole suite red at once (free, loud regression coverage). The TRAP: ubiquity only covers the ONE branch the suite walks (the connection that succeeds); the 3 refusal paths (getpeername ENOTCONN, IsIllegal conf, clone-flood > CLONE_MAX=10) are branches no well-behaved client takes → no honest harness takes them → must be STAGED in the L1. That's why P7bb skipped L2 but not L1. The static `check_clones` twin (no cref_ oracle) is only visible through the public door's clone-reject (the 11th connection). Reuses 009's same-fd trick. Throughline: the most-run fn is also one of the least-tested in its BRANCHES; \"it's on the hot path, it's covered\" feels rigorous and isn't. Footer-links 003/008/009. All claims verified vs s_bsd.rs:1746/1810 + add_connection_diff.rs + read_listener s_bsd.c:1821.\n40\t- 011-the-dial-out-you-can-only-test-by-not-dialing — the OUTBOUND counterpart to 010, closing the I/O trilogy (009 leaves → 010 inbound front door → 011 outbound dial). P7cc ported connect_server (s_bsd.c:2516) + static connect_inet. Thesis = the MIRROR of 010: connect_server's whole point is the connect() succeeding, and that path is UNTESTABLE at L1 (needs a live listening peer + event loop = L2; and all 111 golden scenarios dial INTO the daemon, never make it dial out → the most-tested program has ZERO coverage of this fn's success path). So the L1 oracle diffs the NEGATIVE SPACE — the 3 deterministic ways it refuses to dial: find_server-hit (already present, -1 before any socket, s_bsd.c:2528), the remote-by sendto_one arm, and connect_inet's bind() failure → free_server cleanup (assert highest_fd unchanged + hash clean). Three tests for a connect fn, none of which connect. Secondary beat = the faithful-dead-code edge: DNS-resolution block at s_bsd.c:2544 guarded by `!aconf->ipnum.S_ADDR` is DEAD under AF_INET6 (S_ADDR=s6_addr embedded array → `!&array` constant-false; common/os.h:686) → ported by OMITTING it; dead code has no behavior so the oracle can't tell present from absent, but the oracle also can't PROVE it dead (no test enters the branch) — it's a reading of the macro, not a test result (honest-limit beat). Gotcha: find_server/hash_find_server's suffix-mask scan overwrites '.'→'*' in-place → faults on read-only `c\"...\"` literals (heap-alloc the keys). Footer-links 010/009/003. All claims verified vs s_bsd.c:2516/2528/2544/2726 + connect_server_diff.rs + os.h:686.\n41\t- 012-you-cant-rename-a-symbol-that-isnt-there — the class of fn the L1 oracle STRUCTURALLY can't test: file-`static` fns ([[l1-cref-static-symbol-limit]]). Oracle = `objcopy --redefine-syms foo cref_foo`, map from `nm -g --defined-only` (globals only) → a `static` has internal linkage, no external symbol, no `cref_` twin without editing the C. First hit P6 (`lookup_confhost`, static int s_conf.c → L1 linked but undefined; non-static neighbor `ipv6_convert` got its diff). Two OPPOSITE outs: (a) de-static it (the ONE C edit the faithful port allows — storage-class only, comment every time; `mysk` P7s minted `cref_mysk` free) vs (b) leave it static + port a PRIVATE Rust twin (`unsafe fn`, no `pub`/`#[no_mangle]`) verified only transitively through its exported caller. The 4 P7 twins: `set_sock_opts`(s_bsd.c:1489, via inetport)/`check_init`(:873, via check_client+check_server_init)/`check_clones`(:1577, via add_connection)/`connect_inet`(:2680, via connect_server). Honest limit = the oracle diffs at exported-SYMBOL granularity, so a red caller-diff can't LOCALIZE to the static callee: GCC already inlined the static into its sole remaining caller C-side (PLAN P7z finding), Rust un-fused them for readability, but the diff stays whole-symbol; once the last C caller is ported the C static is guarded out entirely (no oracle at any linkage). The 010 branch-trap recurs: transitive coverage only walks the caller's tested path (`check_clones` age-out branch needs a 2s inter-connection gap no golden scenario waits → covered by a reading, not a test). Funny beat: the twin's `static mut BACKLOG` = a static inside a static (same C keyword, internal-linkage one scope out + persist-across-calls one scope in). Footer-links 003/010/008.

The `.o` is all-or-nothing at the linker, so a mid-port file exists in THREE compiled forms at once: (1) the guarded second compile `s_bsd_link.o` — same source + a parade of `-DPORT_S_BSD_*_P7x` flags, each `#ifndef`-guarding one function body down to a bare prototype so the still-C neighbours resolve to the Rust `#[no_mangle]` def; goes in the real binary via the build.rs `match o { \"s_bsd.o\" => \"s_bsd_link.o\", … }` redirect. (2) the full unguarded `.o` → renamed `foo`→`cref_foo` by ircd-testkit/build.rs (`nm -g --defined-only` → objcopy `--redefine-syms`) into libcref.a, the L1 oracle, which OUTLIVES the C binary. (3) the Rust port itself. Plus the de-static gotcha: `static` fns have no external symbol → can't satisfy C callers OR get a cref_ oracle, so de-static first (storage-class-only, behaviour-preserving, single-TU-no-collision — the one C edit allowed, justified in a source comment every time). Worked example = set_clean_username (P7v, s_auth.c:44-98, callers read_iauth/start_auth). Ends: file gets eaten leaf-by-leaf, then the whole apparatus evaporates into a PORTED tombstone (s_conf.c P6m). All code quotes verified against real source.\n43\t\n44\t- 013-the-function-that-launches-the-program-i-didnt-port — P7dd `start_iauth` (s_bsd.c:625/566), the C launcher of the GREENFIELD iauth from 005 — the seam where the two opposite strategies (rewrite-from-scratch vs translate-byte-for-byte) meet at one fd. NEW oracle puzzle (distinct from 009 kernel-input / 011 no-peer / 012 static-symbol): the fn's success is `fork`+`execl` → the child STOPS being your process (execl replaces the image with the rewritten iauth), so there's nothing in the child to diff. You diff the PARENT-SIDE SHORELINE — the L1 spawn case (start_iauth_diff.rs:152) actually forks BOTH worlds for real (child execl-fails on absent IAUTH_PATH in CI → `_exit(-1)`), captures only `(adfd>=0, O_NONBLOCK set, iauth_spawn==1)` per world, asserts they match + ==`(true,true,1)`. Testing a fork = reaping after one: bounded WNOHANG `reap_children` (:65) so the test can't zombie/hang. CENTERPIECE faithfulness beat = the `vfork()`→`fork()` swap (s_bsd.rs:310): faithful DEVIATION justified (child only close-loop/dup2/execl = async-signal-safe, CoW fork identical result, Rust libc deprecates vfork as memory-unsafe) BUT the failure log still says `\"vfork() failed!\"` — kept the wrong word on purpose: syscall is BELOW the oracle's resolution (unobservable → free to change), the log string is ABOVE it (on the wire to opers → must match). \"Faithful to what's observable, free below it\" crystallized in one string. Honest limits: child plumbing (close-loop/dup2/exec-the-right-binary) unverified at L1 (both children vanish → L2/soak); the non-first-call burst block (`\"%d O\\n\"` of live local clients, gated by the function `static first`) is green by SYMMETRIC ABSENCE — L1 only ever makes a first call so both worlds skip it (needs populated local[] + 2nd call = L2/soak). The 3 function statics last/first/iauth_pid → module-private ([[l1-cref-static-symbol-limit]]/012 callback). Footer-links 005/012/003.

Sits directly above 013's start_iauth (calls it at the bottom). NEW untestability flavor, named distinct from 011: 011 was can't-AFFORD-it (success needs a live peer/event loop = infra); this is can't-SURVIVE-it — the fn's whole JOB is to make the process unobservable (fclose/close 0/1/2, `fork`+parent `exit(0)`, `/dev/tty`+TIOCNOTTY, setpgrp), so running the detach path destroys the test harness (closes cargo's stdout/stderr, exits the parent=the test process). Fork-isolation doesn't save you either: the thing it PRODUCES is a detached process — \"successfully detached\" has no return/struct/errno to diff, the evidence of success is the ABSENCE of everything you'd observe with. Only differentially-safe path = the `bootopt & BOOT_TTY` → `goto init_dgram` short-circuit (=-t \"foreground mode\", ircd.c:1140), which skips the whole detach AND is the only path any rig takes (golden always boots `-t`, ircd-golden/src/lib.rs:50) → testing the config the harness lives in, not a fiction. CENTERPIECE test beat (daemonize_diff.rs:67, one case, GLOBALS_LOCK): pin BOOT_TTY|BOOT_NOIAUTH, resfd=-99 sentinel + adfd=-1, run both worlds; assert resfd CHANGED to a valid fd (init_resolver(0x1f) ran, both worlds agree) AND adfd STAYS -1 (start_iauth(0) reached but short-circuited on BOOT_NOIAUTH) — the inverse check: prove one tail call left a mark and the other correctly left none, because \"nothing happened\" also looks like a broken short-circuit. Secondary faithful-text beat (lighter cousin of 013's vfork-message): C calls `setpgrp(0, getpid())` 2-arg but glibc setpgrp is `setpgrp(void)` (ignores args) → declared 2-arg in Rust to mirror the source verbatim (faithfulness for the READER, below the wire); TIOCNOTTY defined on Linux so ported straight. Honest hole: the ENTIRE detach path has ZERO differential coverage (not a missed branch — the reason the fn exists), ported by inspection-against-the-C only; real coverage = boot WITHOUT -t + check the process actually backgrounded (new session/no ctty/reparented to init) from OUTSIDE = L2/soak, logged in the plan.

THE post on the function the L1 oracle can barely touch: its real input is the kernel (select/accept/recvfrom/exit_client), so there's exactly ONE differentially-safe path — the EMPTY LOOP (`FdAry.highest=-1`, udpfd/resfd/adfd=-1, delay=0 → empty fd_set → `select(0,…,200ms)`=0 → no dispatch → return 0; read_message_diff.rs:73, two cases incl ro=1). Two near-empty asserts for the busiest fn in the program; the test file's own doc says \"Why L1 here is one case by design.\" CENTERPIECE INVERSION (vs 010's coverage-by-ubiquity TRAP): here ubiquity is AIRTIGHT — read_message IS io_loop, so every byte the daemon moves flows through it → the whole golden_*/golden_s2s_* suite (~190 #[test]s, 2 real daemons, real bytes diffed) is its real test end-to-end. \"You don't write a test for the event loop; the event loop runs every other test.\" Mara caveat: L2 is a great gate, lousy DEBUGGER (red = 1-of-50 suspects); the empty-loop L1 catches one thing but localizes. Secondary beats: (1) the DEAD `USE_POLL` half — C read_message is two event loops in a trenchcoat (#if/#else, SET_READ_EVENT/SET_WRITE_EVENT macros serve both backends), USE_POLL off → poll side never compiles → Rust ports select-only, macros evaporate to direct `libc::FD_SET`; ~430-line C fn → one Rust loop. Faithful-dead-code, CLEANER than 011 (compile-time `#if` vs 011's runtime-macro-constant-false).

OPENS on the honest miscount in 014's closing (it said \"two little static helpers\"; it was EIGHT).

THESIS = deleting a variadic isn't about the variadic — by P8 every caller is already Rust, so you move the `va_start` work to the call sites (where `format!` already lives) and the fn loses its `...` → becomes `pub unsafe fn sendto_iauth(line:&[u8])` (s_auth.rs:38). CLEANEST-FIRST insight (title metaphor): `nm` showed ZERO live C callers (all remaining C callers in `#ifdef`'d-out bodies) = \"no riders\"; all 24 callers already Rust → deleting touches only Rust sites I control → picked it first ON PURPOSE as the safe one to learn the mechanics on. Mechanics shown: the before/after `sendto_iauth(c\"%d U %s\",fd,user)`→`sendto_iauth(format!(\"{} U {}\",fd,ia_str(user)).as_bytes())`; `ia_str` (s_auth.rs:77) = lossy C-string read, byte-faithful bc iauth pipe protocol is ASCII. FAITHFUL-BUG beat (REACHABLE-behavior-adjacent but actually unreachable): the C write loop sets `p=abuf` then `write(adfd,abuf,len)` from the BASE while advancing `p+=i` never used → dead cursor, would double-send on a partial write, but tiny lines on a local pipe = one write so it never fires; replicated bug-for-bug anyway (re-issue from base). ORACLE-IS-ALLOWED-TO-BE-VARIADIC beat (the funny one): I can't DEFINE an extern\"C\" variadic in stable Rust but the cref_ oracle is STILL C (unguarded s_auth.o) so `cref_sendto_iauth(fmt,...)` stays variadic — drive same line both ways (oracle vsprintf vs Rust pre-formatted bytes), 2 socketpairs, byte-diff the pipe (sendto_iauth_diff.rs). Honest holes: debug `-1 E last=%u start=%x` pointer line (nondeterministic→not diffed) + lost-slave hard-error branch (can't force fatal write→by-inspection). leveva-deferred note: format!-now not leveva typed Message bc this carries the iauth PIPE protocol `<id> <cat> <info>` not IRC msgs ([[p8-started]] decision).

THESIS = the keystone was mislabeled: 004+016 named `sendto_one` the scary one (~478 call sites + per-recipient formatting), but the per-recipient horror lives in `vsendpreprep` (send.c:388)/the PREFIX senders (P8e `sendto_prefix_one` & kin, pulled a few cuts EARLIER, e<l) — NOT in sendto_one, which is `vsendto_one`→`vsendprep` (send.c:385): format ONCE with libc `vsprintf`, cap 510, CRLF, one delivery → mechanically the SAME format-once shape as 016's sendto_iauth, just with 435 of them. Call-site count measures CENTRALITY not DIFFICULTY (the two-axes line). SECOND honesty beat (the \"more interesting mistake\") = the corrected \"blocked on leveva P10 typed-Numerics\" assumption: the runtime `replies[]` lookup (`reply(ERR_X)`→`char*` fmt at runtime) SEEMED to need typed numerics first, but `vsendprep` delivers via libc `vsprintf` (NOT custom irc_vsprintf), so a libc `snprintf` bridge is byte-identical for literal AND runtime sites alike → rippable NOW, P11 nicety not P8 blocker ([[p8-started]] P8l KEY CORRECTION). TWO builders one core: `wire!` (58 literal-pattern sites, raw-byte, no lossy String) + `reply_one!` (send.rs:519, ~375 runtime `replies[]` sites, libc snprintf into 2048 scratch → core's 510 cap) + 2 direct `rlen += sendto_one` sites (channel.rs read the return). Mara beat = the faithfulness is NARROW: both paths share libc, NOT \"snprintf≈printf close enough\" (if C had used irc_vsprintf this breaks). 435 edits = a 15-agent edit-only fan-out + central verify (Cadey: the feat was the 2 builders+the snprintf==vsprintf proof, NOT 435 hand edits; judgment is the un-parallelizable byte-safe call). Honest count beat: 004/016 guessed 478, real was 435 (logged not silently fixed).

Dated 2026-06-09 (the pivot landed 2026-06-08 14:07 in commit `53106f47`, right after P8v deleted the C tree at 12:58). THESIS = the strangler pattern repeats ONE LEVEL UP: now that all C is gone, the planned in-place idiomatic cleanup (**P9**) is RETIRED — instead the verified-faithful 100%-Rust port (`ircd-common`) is demoted to the **behavioral oracle** for a greenfield idiomatic daemon (`leveva`), pinned differentially via `leveva-integration`, and deleted at parity (exactly the C tree's lifecycle at P8). The \"why P9 earns nothing\" argument: an oracle only has to keep building + passing its tests, it does NOT have to be pretty → polishing throwaway code (the crate slated for deletion) buys a nicer test fixture, nothing more. EMOTIONAL PAYOFF beat (the one that \"sold me\") = greenfield FLIPS the differential harness's meaning: 8 phases of faithful porting FORCED bug-for-bug reproduction (callbacks to 016's dead-p-cursor + 005's rfc931 dead-else-if), but the oracle now lets leveva be *deliberately, documentedly* correct — concrete example = `leveva`'s `casemap` implements the REAL RFC 1459 fold (incl. Scandinavian `[]\\~`↔`{}|^`) while the faithful daemon's `tolowertab` (common/match.c) is ASCII-only; the `leveva-integration` differential doesn't FAIL on the divergence, it ASSERTS it. \"Stopped proving 'I copied this exactly,' started proving 'I diverged here and nowhere else.'\" The honest-cost section: two daemons in the workspace at once (more surface, not less) + THE BET (if leveva stalls the shipping product is the ugly raw-pointer port and P9 was the right call) — hedged by ircd-common being a fully-working byte-proven fallback until parity.

THESIS = turning OFF a differential oracle is stranger than building one (003 built it; this retires it). The IRREVERSIBILITY beat = the reference is a *build* not a recording, so deleting the C means the LAST differential run is the last one FOREVER, its verdict frozen in git, load-bearing under every later correctness claim → ran the whole suite one final time \"slowly, the way you read a contract before signing it.\" THE PAYOFF/TITLE beat = on that final L2 run, L1 all-pass + golden 86 pass / 1 FAIL, and the 1 fail is `golden_s2s_s_serv_stats` where the *reference* is wrong (uninitialized-sendq garbage `…3544950540217614336kB sq`, a different 19-digit number every run; Rust correctly emits `0kB sq`) — so the reference C's LAST act in the repo was to be wrong in a way I'd deliberately chosen NOT to copy; the honest-undercut immediately after (\"right 86×, wrong once on a known bug; 'last thing it did was be wrong' is me compressing it into something that sounds better than it is\").

Dated 2026-06-28. THESIS = the iauth process boundary was load-bearing on EXACTLY ONE thing — the C ircd's single-threaded `select()` loop couldn't afford a blocking DNS/ident/proxy probe, so the work was exiled to a child process over an fd-0 pipe (005 rewrote its insides greenfield but KEPT it a separate program; 013 ported the `fork`/`execl` launcher). leveva runs on tokio → a blocking probe is just an `.await` in the per-connection task → the failure mode the boundary avoided isn't in the building, so the WHOLE apparatus (pipe protocol/socketpair/launcher) is DELETED not ported. Beats: (1) the trait SHRANK from 4 methods (005's `iauth-rs`: name/`init`(InstanceConfig)/`stats_lines`(ModuleStats)/run) to 2 (`leveva-iauth/src/module.rs:57`: just name + `async fn run`) — `init`/`stats_lines` existed ONLY to narrate config/STATS back over the pipe; no socket → no narration → they evaporate (\"what the interface looks like once it stops being a protocol\"). (2) THE SEAM (the proud-of-it part): `Session::feed` is SYNC (NICK/USER/CAP state machine, no await), ident is async + needs only addresses (known at accept), so `main.rs:632` `tokio::spawn`s the `AuthPipeline` concurrently with the handshake; the serve-loop `select!` races a read arm vs an auth arm; registration finalizes only when BOTH gates clear (CAP END + auth verdict) via TWO STASHES (`pending_complete` session.rs:869 / `auth_verdict`) + `try_finalize` (session.rs:1128) which branches on PRESENCE not ARRIVAL ORDER → either order works, no fast-vs-slow-ident bug possible. (3) the `~` rule = a 4-arm match (registration.rs:388): trusted UNIX→bare / OTHER→`~name` / asked-no-answer→`~supplied` / ident-off→trust supplied. (4) HONEST-COST beat = process isolation TRADED AWAY ON PURPOSE: a separate process could leak/OOM/segfault without touching the daemon; in-process = task isolation only (panicked/cancelled task → blank verdict via `v.unwrap_or_default()` main.rs:778, + per-module timeout in pipeline.run) which covers panics+hangs but NOT memory-corruption/unbounded-leak — \"comfortable with the trade, not free\". (5) ORACLE beat (ties 019/020): the old `iauth-rs` WAS the C-iauth differential oracle (socketpair handshake diff), deleted at P12; `parse_ident_reply` was pinned byte-identical to it WHILE IT LIVED then frozen (exactly 020's snapshots-captured-while-green move); now no oracle, confidence = proptests on the pure parser + fake-identd module tests + before/after-USER seam tests; ALSO dropped the C result-cache + STATS counters (an `.await` the runtime overlaps makes the cache buy ~nothing; it never changed a *decision*).

Dated 2026-06-29 (weight 22; sits just after 021's 06-28; blog still lags the code — these slices landed 2026-06-14..20). TOML `+++` frontmatter, zola `@/blog/NNN-slug.md` links. THESIS = a plain ban is a *string* (a `nick!user@host` glob, a fact written down once and compared forever); an **extban** (`$[~]<type>[:data]`, leading `$`) is a *question the server asks fresh every time* (`$a:bob`=logged-in-as-bob, `$~z`=not-on-TLS, `$o`=oper, `$c:#staff`=in-#staff-right-now) — a predicate evaluated against you whose answer can differ at join vs ten minutes later. Once a ban is a question not a fact, THREE free things become deliberate decisions (the frontmatter's \"three things\"): (1) the **third Verdict** `Invalid` (extban/mod.rs:40) = \"this isn't a coherent question\" — a property of the MASK not the subject (`$q` unknown type, `$c` w/ no chan); load-bearing in negation (mod.rs:266: `~` flips Match↔NoMatch but Invalid-stays-Invalid-even-negated, so `$~q` never matches anyone instead of banning the whole internet — a real security hole if you collapse Invalid into NoMatch) AND in add-time validity. (2) **WHEN to ask** — JOIN gate only was quietly broken (a `$a:troll` set after the troll joined did nothing); slice 214 added the **speech plane** (`can_send` channel.rs:1713 → `CanSend::Banned` → 404, same Subject+LiveChannels eval as `check_join`), so a dynamic extban re-evaluates on EVERY message; voice+ bypasses both `+m` and the ban. (3) **which questions are unsafe to INVERT into an exception** — `$r` realname (realname.rs:26: `if mode_type.is_exception() return Invalid`) bc a spoofable gecos as a `+e` key = skeleton key; `$c` (channel.rs) refuses a `+s`/`+p` referent (`ChannelPresence::NonPublic → Invalid`) bc answering would leak private membership — a 2-valued ban has nowhere to put \"I refuse to answer this\". COMPOSABILITY climax = `$&`(AND)/`$|`(OR) combinators (combi.rs:51, `$&:a,~z`, depth cap 5 / 10 nodes / BANLEN 195) + the faithful subject-dependent-validity quirk (child *type* always checked, child *data* only to short-circuit → validity depends on who you ask; left weird on purpose). The `LiveChannels` adapter (channel.rs:68) resolves `$c`/`$j` over the already-locked map w/ a `Cell` depth-1 guard (charybdis uses a static; leveva is multi-connection). HONEST beats: NO oracle (IRCnet 2.11 never had extbans → ported from Elemental-IRCd `extensions/extb_*.c` by READING, C quoted in each handler's doc comment, confidence = units+proptests not a byte-diff; ties 018-021); built the 9 leaf handlers via an **ultracode workflow** (one agent per `extb_*.c`), combinators by hand (the one place handlers must know each other). DIVERGENCES owned (the \"I changed the alphabet\" section): leveva `$m`=usermode (charybdis m=hostmask/u=usermode), NO plain-hostmask extban (use `$x:n!u@h#*`); NO `$q` quiet list (`+q`=owner per [[leveva-elemental-channel-modes]], mute plane is `+b`-driven).

Dated 2026-06-30 (weight 23; one-per-day after 022's 06-29; blog still lags the code — CAP framework landed slice 48, 2026-06-09). TOML `+++`, zola `@/blog/NNN-slug.md`. THESIS = CAP is the ONE corner of IRC that negotiates instead of assuming — old IRC has no version field, unknown commands just get `421`; CAP is the handshake (BEFORE registration finishes — `negotiating` flag slams a brake until `CAP END`) where client+server agree which extensions are live. The spine = the **locked scope rule** (with the user, [[leveva-ircv3-track]]): the negotiation *mechanism* and each capability's *behavior* are SEPARATE slices; slice 48 shipped the framework + `cap-notify` ONLY (the one cap the framework itself honors), every behavior cap (multi-prefix/server-time/…) is its own later slice. Beats: (1) `CapState` = 3 fields (`version` Option<u32> that NEVER downgrades — `cur.max(v)` at cap.rs:605, bc 302 is the threshold unlocking values/multiline/implicit-cap-notify so a downgrade would strip negotiated features; `enabled` BTreeSet; `negotiating` brake). (2) the registration-suspend brake **feeds post 21's two-gate finalize** — `try_finalize` bails on `self.cap.is_negotiating()` (session.rs:1129); CAP END is the OTHER gate next to the auth verdict (direct 021 callback). (3) `REQ` is all-or-nothing = a **prepare-then-commit transaction** (validate every token into a `planned` scratch vec, NAK the whole set on any unknown, only then mutate `enabled`; cap.rs:686); admitted the first version enabled-as-it-walked-then-rolled-back (strictly worse). (4) PAYOFF = `ClientCaps` (cap.rs:339) is **25 bool fields**, one per behavior cap; adding the 26th = add a SUPPORTED row + a bool + a `client_caps()` copy line + read `client.caps.x` in one handler, touching the negotiation code nothing — the empty switchboard pays off. (5) HONEST WART (the \"my clean abstraction grew warts\" beat): the design was \"every cap is a static `SUPPORTED` table row\" — TRUE for ~20, a LIE for 3 (`sasl` needs a linked services agent, `chathistory` needs an open history DB, `sts` is per-socket plaintext-vs-TLS) → those are **injected at LS-render time** not in the `const` table (cap.rs:623); left the 3 holes visible w/ comments rather than burying them. (6) NO ORACLE (ties 018–022): IRCnet 2.11 had no CAP (charybdis/IRCv3-era), so confidence = pure-fn units + proptest (never-panics/never-half-commits) + a boot-golden socket handshake, NOT a byte-diff. CLOSING ties to the opening hook (assume-vs-ask; \"neither has to pretend the other is its own age\").

PRIOR most recent = 022 (extbans; a ban that asks a question; string→predicate; the third Verdict Invalid; JOIN+speech-plane enforcement; questions unsafe to invert into an exception; `$&`/`$|` composition; no oracle; the `$m`/no-`$q` divergences). PRIOR most recent = 021 (native-async iauth; the process boundary was load-bearing on the C single-threaded loop; tokio deletes it; the concurrent-spawn/two-stash seam; isolation traded for an `.await`; no oracle). PRIOR most recent = 020 (the P8v switch-off finale; turning the oracle OFF; the final run's 1 red was the reference's own bug; the differential→snapshot honest downgrade). PRIOR most recent = 019 (the first leveva-feature post, netsplit-merge consensus = a less-than sign + the loser gets wiped; no oracle behind it). PRIOR most recent = 018 (the leveva pivot / P9 retired — strangler one level up; the port IS the oracle now; casemap-divergence = finally-allowed-to-be-correct payoff; the bet). **STILL UN-TAKEN big beats:** (1) **the prefix senders / `vsendpreprep` per-recipient `:nick!user@host` collapse** (P8e `prep_preprep`) — the LITERAL payoff teased in 016+017 AND in 017's close, still the strongest pure-mechanics candidate. (2) ~~\"not one line of C remains\" — the P8v finale~~ **TAKEN by 020** (the oracle switch-off). (3) a **leveva feature-work** post now that P11/P12 are done (e.g. the IRCv3 cap track, elemental channel modes/extbans, the charybdis-port slices, native async iauth) — the migration is FINISHED so leveva posts would be standalone-product posts, a new sub-genre for the series. **NOTE: the blog now lags the code badly** — per [[p8-started]] P8 is COMPLETE (all trampolines a–m + data globals n–r + version.c t + test-migration s done) and [[leveva-pivot-p9-retired]] P9 is RETIRED with the project pivoted to greenfield `leveva` (P10/P11 in progress: registration state machine, PRIVMSG/mailbox). Big un-taken beats now available: (1) **the prefix senders / `vsendpreprep` per-recipient `:nick!user@host` collapse** (P8e `prep_preprep`) — the LITERAL payoff of 016+017's recurring cliffhanger, explicitly teased in 017's close (\"deserve their own post\"); STRONGEST next candidate.

The P8 keystones (`sendto_one`/`sendto_flag`, per-recipient `va_arg` in vsendpreprep — the hard ones 004+016 both flag) are the obvious next blog beats AS THEY LAND (not yet ported as of 2026-06-07). Earlier: 015 (read_message, P7ff — the event-loop spine; ONE empty-loop L1 case for the busiest fn + the L2-ubiquity-is-airtight-here inversion vs 010's trap; dead-USE_POLL-half + 8-statics-no-oracle beats; opened on 014's eight-not-two miscount). 009→010→011 was the I/O trilogy; 012 = coverage-limits at symbol granularity; 013 closed the 005 iauth loop (the launcher); 014 = the boot detach that CALLS start_iauth; 015 = the loop those boot fns hand control to. **s_bsd.c now has NO logic left** — only data globals (local[]/highest_fd/timeofday/fd arrays), a later-phase/P9 problem.

Still open beyond that: the variadic-trampoline family (flagged for 004, may have been folded in — check); the 56-cluster connected-component finding from P5 (touched in 006/008, runner-up for 012 — \"the unit of migration isn't the function\"); \"faithful to the bugs\" bug-for-bug reproduction (offered for 009, NOT picked — best examples spent in 005/006; the faithful-DEAD-CODE sibling is spent in 011/015, so a future bug-for-bug post must stick to REACHABLE-behavior bugs).

Decision rule: where does the contract live? ABI → translate; text socket → rewrite + diff the wire.\n- 006-the-retrospective-is-where-you-round-up — the P0-P6 halfway retrospective, framed as \"a retrospective is where you round up.\" The un-rounded ledger of what the differential harness caught: the c_char-signedness test bug that only failed on aarch64; the clean-checkout s2s golden red because reference-C `report_myservers` prints an uninitialized peer sendq (`3544950785030750208kB`) — oracle so precise it catches the reference being nondeterministic; brief callback to the rfc931 bug-on-purpose; `calculate_preference` calls libc `pow` via FFI (not `f64::powf`) so a last-ULP drift can't flip the `(u_int)` truncation on the wire. Harder-than-planned: P5's 56 clusters over shared file-statics (can't port one m_* without its neighbors); `replies[]`/`alphabet_id` dumped from the oracle not text-extracted. Cost: P9-P12 exist to un-do the faithfulness P1-P8 built.\n- 007-prove-the-structs — the P0b foundation post ([[p0b-bindgen-constraints]]): before any faithful port, prove Rust and C agree on struct layout byte-for-byte (else every port silently corrupts shared memory). Two SILENT bindgen failures: (1) bindgen defaults to C++ → chokes on `class` field name (class_def.h:25, struct_def.h:323) + `register` storage class → clang error-recovery leaves structs as opaque `pub struct X { _address: u8 }` blobs, build still green; fix `.clang_arg(\"-x\").clang_arg(\"c\")`; diagnose with `grep -c 'pub _address: u8,'`. (2) bindgen 0.70 picks forward-decl over later definition (struct_def.h:23-40 `typedef struct X Y;`) → opaque again; 0.72 fixes. Then the real point: \"bindgen agrees with bindgen\" ≠ \"bindgen agrees with the real compiler\" (config drift: MAXCONNECTIONS/USE_IAUTH/AFINET=AF_INET6 move fields). Drift net = ctruth.c (same flags, exports cref_sizeof/alignof/offsetof for 14 structs + aClient's 24 local-tail offsets + CLIENT_REMOTE_SIZE=offsetof(count) + MAXCONNECTIONS) + layout.rs (`cargo test`, red on drift). Honest holes: the 256-tables + local[] are sizeless `extern[]` → unreachable, asserted later at P1/P7; MAXCONNECTIONS is the cheap proxy. Throughline: build the thing that catches you before you can be wrong.\n- 009-hand-both-of-them-the-same-socket — diffing I/O functions in the L1 oracle (P7w `send_authports`/`read_authports`, P7z `check_client`). Earlier posts diffed PURE fns; these call `getpeername`/`getsockname`/`read`/`write` so their real input is the kernel, not their args. Thesis: mocking a syscall makes both impls agree with the FIXTURE not the kernel → defeats a faithfulness oracle. Fix = hand the C `cref_` original and the Rust port the SAME real fd (one connected IPv6-loopback socket for getsockname/getpeername, one AF_UNIX socketpair for pipe I/O), separate aClients (the fn mutates them), diff what comes out. Beats: the socketpair-leaves-`sin6_port`-untouched trap (C reads uninit stack, Rust reads zeroed → FALSE diff → use a real `::1` socket when the bytes-under-test are kernel-filled, socketpair when they're bytes YOU wrote); the `World` struct + `GLOBALS_LOCK` for `cref_`-twinned process globals under parallel `#[test]`s ([[p7-l1-shared-global-race]]); empty-`conf` → `attach_Iline` returns -2 deterministically (no fixture); the faithful 4×`c_ulong` over-read of a 16-byte `h_addr` (pad to 32 in the harness, ship the bug). Quotes verified against check_client_diff.rs/authports_diff.rs + s_bsd.c:914/871 + s_auth.c:690/740.\n- 010-you-dont-write-a-test-for-the-front-door — coverage-by-ubiquity + the trap in \"it's covered\". P7bb ported `add_connection` (s_bsd.c:1641), the universal inbound acceptor (every connection enters via read_listener's accept loop → add_connection), so it got NO new L2 golden test — all 111 golden scenarios already flow through it; a botched success path turns the whole suite red at once (free, loud regression coverage). The TRAP: ubiquity only covers the ONE branch the suite walks (the connection that succeeds); the 3 refusal paths (getpeername ENOTCONN, IsIllegal conf, clone-flood > CLONE_MAX=10) are branches no well-behaved client takes → no honest harness takes them → must be STAGED in the L1. That's why P7bb skipped L2 but not L1. The static `check_clones` twin (no cref_ oracle) is only visible through the public door's clone-reject (the 11th connection). Reuses 009's same-fd trick. Throughline: the most-run fn is also one of the least-tested in its BRANCHES; \"it's on the hot path, it's covered\" feels rigorous and isn't. Footer-links 003/008/009. All claims verified vs s_bsd.rs:1746/1810 + add_connection_diff.rs + read_listener s_bsd.c:1821.\n- 011-the-dial-out-you-can-only-test-by-not-dialing — the OUTBOUND counterpart to 010, closing the I/O trilogy (009 leaves → 010 inbound front door → 011 outbound dial). P7cc ported connect_server (s_bsd.c:2516) + static connect_inet. Thesis = the MIRROR of 010: connect_server's whole point is the connect() succeeding, and that path is UNTESTABLE at L1 (needs a live listening peer + event loop = L2; and all 111 golden scenarios dial INTO the daemon, never make it dial out → the most-tested program has ZERO coverage of this fn's success path). So the L1 oracle diffs the NEGATIVE SPACE — the 3 deterministic ways it refuses to dial: find_server-hit (already present, -1 before any socket, s_bsd.c:2528), the remote-by sendto_one arm, and connect_inet's bind() failure → free_server cleanup (assert highest_fd unchanged + hash clean). Three tests for a connect fn, none of which connect. Secondary beat = the faithful-dead-code edge: DNS-resolution block at s_bsd.c:2544 guarded by `!aconf->ipnum.S_ADDR` is DEAD under AF_INET6 (S_ADDR=s6_addr embedded array → `!&array` constant-false; common/os.h:686) → ported by OMITTING it; dead code has no behavior so the oracle can't tell present from absent, but the oracle also can't PROVE it dead (no test enters the branch) — it's a reading of the macro, not a test result (honest-limit beat). Gotcha: find_server/hash_find_server's suffix-mask scan overwrites '.'→'*' in-place → faults on read-only `c\"...\"` literals (heap-alloc the keys). Footer-links 010/009/003.

Oracle = `objcopy --redefine-syms foo cref_foo`, map from `nm -g --defined-only` (globals only) → a `static` has internal linkage, no external symbol, no `cref_` twin without editing the C. First hit P6 (`lookup_confhost`, static int s_conf.c → L1 linked but undefined; non-static neighbor `ipv6_convert` got its diff). Two OPPOSITE outs: (a) de-static it (the ONE C edit the faithful port allows — storage-class only, comment every time; `mysk` P7s minted `cref_mysk` free) vs (b) leave it static + port a PRIVATE Rust twin (`unsafe fn`, no `pub`/`#[no_mangle]`) verified only transitively through its exported caller. The 4 P7 twins: `set_sock_opts`(s_bsd.c:1489, via inetport)/`check_init`(:873, via check_client+check_server_init)/`check_clones`(:1577, via add_connection)/`connect_inet`(:2680, via connect_server). Honest limit = the oracle diffs at exported-SYMBOL granularity, so a red caller-diff can't LOCALIZE to the static callee: GCC already inlined the static into its sole remaining caller C-side (PLAN P7z finding), Rust un-fused them for readability, but the diff stays whole-symbol; once the last C caller is ported the C static is guarded out entirely (no oracle at any linkage). The 010 branch-trap recurs: transitive coverage only walks the caller's tested path (`check_clones` age-out branch needs a 2s inter-connection gap no golden scenario waits → covered by a reading, not a test). Funny beat: the twin's `static mut BACKLOG` = a static inside a static (same C keyword, internal-linkage one scope out + persist-across-calls one scope in). Footer-links 003/010/008.

The `.o` is all-or-nothing at the linker, so a mid-port file exists in THREE compiled forms at once: (1) the guarded second compile `s_bsd_link.o` — same source + a parade of `-DPORT_S_BSD_*_P7x` flags, each `#ifndef`-guarding one function body down to a bare prototype so the still-C neighbours resolve to the Rust `#[no_mangle]` def; goes in the real binary via the build.rs `match o { \"s_bsd.o\" => \"s_bsd_link.o\", … }` redirect. (2) the full unguarded `.o` → renamed `foo`→`cref_foo` by ircd-testkit/build.rs (`nm -g --defined-only` → objcopy `--redefine-syms`) into libcref.a, the L1 oracle, which OUTLIVES the C binary. (3) the Rust port itself. Plus the de-static gotcha: `static` fns have no external symbol → can't satisfy C callers OR get a cref_ oracle, so de-static first (storage-class-only, behaviour-preserving, single-TU-no-collision — the one C edit allowed, justified in a source comment every time). Worked example = set_clean_username (P7v, s_auth.c:44-98, callers read_iauth/start_auth). Ends: file gets eaten leaf-by-leaf, then the whole apparatus evaporates into a PORTED tombstone (s_conf.c P6m). All code quotes verified against real source.\n\n- 013-the-function-that-launches-the-program-i-didnt-port — P7dd `start_iauth` (s_bsd.c:625/566), the C launcher of the GREENFIELD iauth from 005 — the seam where the two opposite strategies (rewrite-from-scratch vs translate-byte-for-byte) meet at one fd. NEW oracle puzzle (distinct from 009 kernel-input / 011 no-peer / 012 static-symbol): the fn's success is `fork`+`execl` → the child STOPS being your process (execl replaces the image with the rewritten iauth), so there's nothing in the child to diff. You diff the PARENT-SIDE SHORELINE — the L1 spawn case (start_iauth_diff.rs:152) actually forks BOTH worlds for real (child execl-fails on absent IAUTH_PATH in CI → `_exit(-1)`), captures only `(adfd>=0, O_NONBLOCK set, iauth_spawn==1)` per world, asserts they match + ==`(true,true,1)`. Testing a fork = reaping after one: bounded WNOHANG `reap_children` (:65) so the test can't zombie/hang. CENTERPIECE faithfulness beat = the `vfork()`→`fork()` swap (s_bsd.rs:310): faithful DEVIATION justified (child only close-loop/dup2/execl = async-signal-safe, CoW fork identical result, Rust libc deprecates vfork as memory-unsafe) BUT the failure log still says `\"vfork() failed!\"` — kept the wrong word on purpose: syscall is BELOW the oracle's resolution (unobservable → free to change), the log string is ABOVE it (on the wire to opers → must match). \"Faithful to what's observable, free below it\" crystallized in one string. Honest limits: child plumbing (close-loop/dup2/exec-the-right-binary) unverified at L1 (both children vanish → L2/soak); the non-first-call burst block (`\"%d O\\n\"` of live local clients, gated by the function `static first`) is green by SYMMETRIC ABSENCE — L1 only ever makes a first call so both worlds skip it (needs populated local[] + 2nd call = L2/soak). The 3 function statics last/first/iauth_pid → module-private ([[l1-cref-static-symbol-limit]]/012 callback). Footer-links 005/012/003. Verified vs s_bsd.c:566/625/642 + s_bsd.rs:236/310/315 + start_iauth_diff.rs:65/152.\n\n- 014-a-daemons-first-job-is-to-stop-being-watched — P7ee `daemonize` (s_bsd.c:794), the boot detach glue called once from ircd.c:1152 (warning-label comment \"daemonize() closes 0,1,2 -- make sure you don't have any fd open\"). Sits directly above 013's start_iauth (calls it at the bottom). NEW untestability flavor, named distinct from 011: 011 was can't-AFFORD-it (success needs a live peer/event loop = infra); this is can't-SURVIVE-it — the fn's whole JOB is to make the process unobservable (fclose/close 0/1/2, `fork`+parent `exit(0)`, `/dev/tty`+TIOCNOTTY, setpgrp), so running the detach path destroys the test harness (closes cargo's stdout/stderr, exits the parent=the test process). Fork-isolation doesn't save you either: the thing it PRODUCES is a detached process — \"successfully detached\" has no return/struct/errno to diff, the evidence of success is the ABSENCE of everything you'd observe with. Only differentially-safe path = the `bootopt & BOOT_TTY` → `goto init_dgram` short-circuit (=-t \"foreground mode\", ircd.c:1140), which skips the whole detach AND is the only path any rig takes (golden always boots `-t`, ircd-golden/src/lib.rs:50) → testing the config the harness lives in, not a fiction. CENTERPIECE test beat (daemonize_diff.rs:67, one case, GLOBALS_LOCK): pin BOOT_TTY|BOOT_NOIAUTH, resfd=-99 sentinel + adfd=-1, run both worlds; assert resfd CHANGED to a valid fd (init_resolver(0x1f) ran, both worlds agree) AND adfd STAYS -1 (start_iauth(0) reached but short-circuited on BOOT_NOIAUTH) — the inverse check: prove one tail call left a mark and the other correctly left none, because \"nothing happened\" also looks like a broken short-circuit. Secondary faithful-text beat (lighter cousin of 013's vfork-message): C calls `setpgrp(0, getpid())` 2-arg but glibc setpgrp is `setpgrp(void)` (ignores args) → declared 2-arg in Rust to mirror the source verbatim (faithfulness for the READER, below the wire); TIOCNOTTY defined on Linux so ported straight. Honest hole: the ENTIRE detach path has ZERO differential coverage (not a missed branch — the reason the fn exists), ported by inspection-against-the-C only; real coverage = boot WITHOUT -t + check the process actually backgrounded (new session/no ctty/reparented to init) from OUTSIDE = L2/soak, logged in the plan.

THE post on the function the L1 oracle can barely touch: its real input is the kernel (select/accept/recvfrom/exit_client), so there's exactly ONE differentially-safe path — the EMPTY LOOP (`FdAry.highest=-1`, udpfd/resfd/adfd=-1, delay=0 → empty fd_set → `select(0,…,200ms)`=0 → no dispatch → return 0; read_message_diff.rs:73, two cases incl ro=1). Two near-empty asserts for the busiest fn in the program; the test file's own doc says \"Why L1 here is one case by design.\" CENTERPIECE INVERSION (vs 010's coverage-by-ubiquity TRAP): here ubiquity is AIRTIGHT — read_message IS io_loop, so every byte the daemon moves flows through it → the whole golden_*/golden_s2s_* suite (~190 #[test]s, 2 real daemons, real bytes diffed) is its real test end-to-end. \"You don't write a test for the event loop; the event loop runs every other test.\" Mara caveat: L2 is a great gate, lousy DEBUGGER (red = 1-of-50 suspects); the empty-loop L1 catches one thing but localizes. Secondary beats: (1) the DEAD `USE_POLL` half — C read_message is two event loops in a trenchcoat (#if/#else, SET_READ_EVENT/SET_WRITE_EVENT macros serve both backends), USE_POLL off → poll side never compiles → Rust ports select-only, macros evaporate to direct `libc::FD_SET`; ~430-line C fn → one Rust loop. Faithful-dead-code, CLEANER than 011 (compile-time `#if` vs 011's runtime-macro-constant-false). (2) the 8 statics (completed_connection/read_listener/read_packet/client_packet/ircd_no_fakelag/do_dns_async/polludp/check_ping) — all `static`, no cref_ oracle ([[l1-cref-static-symbol-limit]]/012), ported as module-private twins w/ read_message → 8 of 9 fns in the I/O-engine heart have ZERO L1 oracle, the 9th has the empty-loop case; biggest P7 port, thinnest L1 footprint. OPENS on the honest miscount in 014's closing (it said \"two little static helpers\"; it was EIGHT). Honest ledger: skeleton proven, all dispatch (accept/read/write/exit_client/do_dns_async/polludp/check_ping) untested-by-design → L2/soak.

THESIS = deleting a variadic isn't about the variadic — by P8 every caller is already Rust, so you move the `va_start` work to the call sites (where `format!` already lives) and the fn loses its `...` → becomes `pub unsafe fn sendto_iauth(line:&[u8])` (s_auth.rs:38). CLEANEST-FIRST insight (title metaphor): `nm` showed ZERO live C callers (all remaining C callers in `#ifdef`'d-out bodies) = \"no riders\"; all 24 callers already Rust → deleting touches only Rust sites I control → picked it first ON PURPOSE as the safe one to learn the mechanics on. Mechanics shown: the before/after `sendto_iauth(c\"%d U %s\",fd,user)`→`sendto_iauth(format!(\"{} U {}\",fd,ia_str(user)).as_bytes())`; `ia_str` (s_auth.rs:77) = lossy C-string read, byte-faithful bc iauth pipe protocol is ASCII. FAITHFUL-BUG beat (REACHABLE-behavior-adjacent but actually unreachable): the C write loop sets `p=abuf` then `write(adfd,abuf,len)` from the BASE while advancing `p+=i` never used → dead cursor, would double-send on a partial write, but tiny lines on a local pipe = one write so it never fires; replicated bug-for-bug anyway (re-issue from base). ORACLE-IS-ALLOWED-TO-BE-VARIADIC beat (the funny one): I can't DEFINE an extern\"C\" variadic in stable Rust but the cref_ oracle is STILL C (unguarded s_auth.o) so `cref_sendto_iauth(fmt,...)` stays variadic — drive same line both ways (oracle vsprintf vs Rust pre-formatted bytes), 2 socketpairs, byte-diff the pipe (sendto_iauth_diff.rs). Honest holes: debug `-1 E last=%u start=%x` pointer line (nondeterministic→not diffed) + lost-slave hard-error branch (can't force fatal write→by-inspection). leveva-deferred note: format!-now not leveva typed Message bc this carries the iauth PIPE protocol `<id> <cat> <info>` not IRC msgs ([[p8-started]] decision).

THESIS = the keystone was mislabeled: 004+016 named `sendto_one` the scary one (~478 call sites + per-recipient formatting), but the per-recipient horror lives in `vsendpreprep` (send.c:388)/the PREFIX senders (P8e `sendto_prefix_one` & kin, pulled a few cuts EARLIER, e<l) — NOT in sendto_one, which is `vsendto_one`→`vsendprep` (send.c:385): format ONCE with libc `vsprintf`, cap 510, CRLF, one delivery → mechanically the SAME format-once shape as 016's sendto_iauth, just with 435 of them. Call-site count measures CENTRALITY not DIFFICULTY (the two-axes line). SECOND honesty beat (the \"more interesting mistake\") = the corrected \"blocked on leveva P10 typed-Numerics\" assumption: the runtime `replies[]` lookup (`reply(ERR_X)`→`char*` fmt at runtime) SEEMED to need typed numerics first, but `vsendprep` delivers via libc `vsprintf` (NOT custom irc_vsprintf), so a libc `snprintf` bridge is byte-identical for literal AND runtime sites alike → rippable NOW, P11 nicety not P8 blocker ([[p8-started]] P8l KEY CORRECTION). TWO builders one core: `wire!` (58 literal-pattern sites, raw-byte, no lossy String) + `reply_one!` (send.rs:519, ~375 runtime `replies[]` sites, libc snprintf into 2048 scratch → core's 510 cap) + 2 direct `rlen += sendto_one` sites (channel.rs read the return). Mara beat = the faithfulness is NARROW: both paths share libc, NOT \"snprintf≈printf close enough\" (if C had used irc_vsprintf this breaks). 435 edits = a 15-agent edit-only fan-out + central verify (Cadey: the feat was the 2 builders+the snprintf==vsprintf proof, NOT 435 hand edits; judgment is the un-parallelizable byte-safe call). Honest count beat: 004/016 guessed 478, real was 435 (logged not silently fixed).

THESIS = the strangler pattern repeats ONE LEVEL UP: now that all C is gone, the planned in-place idiomatic cleanup (**P9**) is RETIRED — instead the verified-faithful 100%-Rust port (`ircd-common`) is demoted to the **behavioral oracle** for a greenfield idiomatic daemon (`leveva`), pinned differentially via `leveva-integration`, and deleted at parity (exactly the C tree's lifecycle at P8). The \"why P9 earns nothing\" argument: an oracle only has to keep building + passing its tests, it does NOT have to be pretty → polishing throwaway code (the crate slated for deletion) buys a nicer test fixture, nothing more. EMOTIONAL PAYOFF beat (the one that \"sold me\") = greenfield FLIPS the differential harness's meaning: 8 phases of faithful porting FORCED bug-for-bug reproduction (callbacks to 016's dead-p-cursor + 005's rfc931 dead-else-if), but the oracle now lets leveva be *deliberately, documentedly* correct — concrete example = `leveva`'s `casemap` implements the REAL RFC 1459 fold (incl. Scandinavian `[]\\~`↔`{}|^`) while the faithful daemon's `tolowertab` (common/match.c) is ASCII-only; the `leveva-integration` differential doesn't FAIL on the divergence, it ASSERTS it. \"Stopped proving 'I copied this exactly,' started proving 'I diverged here and nowhere else.'\" The honest-cost section: two daemons in the workspace at once (more surface, not less) + THE BET (if leveva stalls the shipping product is the ugly raw-pointer port and P9 was the right call) — hedged by ircd-common being a fully-working byte-proven fallback until parity.

THESIS = turning OFF a differential oracle is stranger than building one (003 built it; this retires it).

Dated 2026-06-28. THESIS = the iauth process boundary was load-bearing on EXACTLY ONE thing — the C ircd's single-threaded `select()` loop couldn't afford a blocking DNS/ident/proxy probe, so the work was exiled to a child process over an fd-0 pipe (005 rewrote its insides greenfield but KEPT it a separate program; 013 ported the `fork`/`execl` launcher). leveva runs on tokio → a blocking probe is just an `.await` in the per-connection task → the failure mode the boundary avoided isn't in the building, so the WHOLE apparatus (pipe protocol/socketpair/launcher) is DELETED not ported. Beats: (1) the trait SHRANK from 4 methods (005's `iauth-rs`: name/`init`(InstanceConfig)/`stats_lines`(ModuleStats)/run) to 2 (`leveva-iauth/src/module.rs:57`: just name + `async fn run`) — `init`/`stats_lines` existed ONLY to narrate config/STATS back over the pipe; no socket → no narration → they evaporate (\"what the interface looks like once it stops being a protocol\"). (2) THE SEAM (the proud-of-it part): `Session::feed` is SYNC (NICK/USER/CAP state machine, no await), ident is async + needs only addresses (known at accept), so `main.rs:632` `tokio::spawn`s the `AuthPipeline` concurrently with the handshake; the serve-loop `select!` races a read arm vs an auth arm; registration finalizes only when BOTH gates clear (CAP END + auth verdict) via TWO STASHES (`pending_complete` session.rs:869 / `auth_verdict`) + `try_finalize` (session.rs:1128) which branches on PRESENCE not ARRIVAL ORDER → either order works, no fast-vs-slow-ident bug possible. (3) the `~` rule = a 4-arm match (registration.rs:388): trusted UNIX→bare / OTHER→`~name` / asked-no-answer→`~supplied` / ident-off→trust supplied. (4) HONEST-COST beat = process isolation TRADED AWAY ON PURPOSE: a separate process could leak/OOM/segfault without touching the daemon; in-process = task isolation only (panicked/cancelled task → blank verdict via `v.unwrap_or_default()` main.rs:778, + per-module timeout in pipeline.run) which covers panics+hangs but NOT memory-corruption/unbounded-leak — \"comfortable with the trade, not free\". (5) ORACLE beat (ties 019/020): the old `iauth-rs` WAS the C-iauth differential oracle (socketpair handshake diff), deleted at P12; `parse_ident_reply` was pinned byte-identical to it WHILE IT LIVED then frozen (exactly 020's snapshots-captured-while-green move); now no oracle, confidence = proptests on the pure parser + fake-identd module tests + before/after-USER seam tests; ALSO dropped the C result-cache + STATS counters (an `.await` the runtime overlaps makes the cache buy ~nothing; it never changed a *decision*).

Dated 2026-06-29 (weight 22; sits just after 021's 06-28; blog still lags the code — these slices landed 2026-06-14..20). TOML `+++` frontmatter, zola `@/blog/NNN-slug.md` links. THESIS = a plain ban is a *string* (a `nick!user@host` glob, a fact written down once and compared forever); an **extban** (`$[~]<type>[:data]`, leading `$`) is a *question the server asks fresh every time* (`$a:bob`=logged-in-as-bob, `$~z`=not-on-TLS, `$o`=oper, `$c:#staff`=in-#staff-right-now) — a predicate evaluated against you whose answer can differ at join vs ten minutes later. Once a ban is a question not a fact, THREE free things become deliberate decisions (the frontmatter's \"three things\"): (1) the **third Verdict** `Invalid` (extban/mod.rs:40) = \"this isn't a coherent question\" — a property of the MASK not the subject (`$q` unknown type, `$c` w/ no chan); load-bearing in negation (mod.rs:266: `~` flips Match↔NoMatch but Invalid-stays-Invalid-even-negated, so `$~q` never matches anyone instead of banning the whole internet — a real security hole if you collapse Invalid into NoMatch) AND in add-time validity. (2) **WHEN to ask** — JOIN gate only was quietly broken (a `$a:troll` set after the troll joined did nothing); slice 214 added the **speech plane** (`can_send` channel.rs:1713 → `CanSend::Banned` → 404, same Subject+LiveChannels eval as `check_join`), so a dynamic extban re-evaluates on EVERY message; voice+ bypasses both `+m` and the ban. (3) **which questions are unsafe to INVERT into an exception** — `$r` realname (realname.rs:26: `if mode_type.is_exception() return Invalid`) bc a spoofable gecos as a `+e` key = skeleton key; `$c` (channel.rs) refuses a `+s`/`+p` referent (`ChannelPresence::NonPublic → Invalid`) bc answering would leak private membership — a 2-valued ban has nowhere to put \"I refuse to answer this\". COMPOSABILITY climax = `$&`(AND)/`$|`(OR) combinators (combi.rs:51, `$&:a,~z`, depth cap 5 / 10 nodes / BANLEN 195) + the faithful subject-dependent-validity quirk (child *type* always checked, child *data* only to short-circuit → validity depends on who you ask; left weird on purpose). The `LiveChannels` adapter (channel.rs:68) resolves `$c`/`$j` over the already-locked map w/ a `Cell` depth-1 guard (charybdis uses a static; leveva is multi-connection). HONEST beats: NO oracle (IRCnet 2.11 never had extbans → ported from Elemental-IRCd `extensions/extb_*.c` by READING, C quoted in each handler's doc comment, confidence = units+proptests not a byte-diff; ties 018-021); built the 9 leaf handlers via an **ultracode workflow** (one agent per `extb_*.c`), combinators by hand (the one place handlers must know each other). DIVERGENCES owned (the \"I changed the alphabet\" section): leveva `$m`=usermode (charybdis m=hostmask/u=usermode), NO plain-hostmask extban (use `$x:n!u@h#*`); NO `$q` quiet list (`+q`=owner per [[leveva-elemental-channel-modes]], mute plane is `+b`-driven).

Dated 2026-06-30 (weight 23; one-per-day after 022's 06-29; blog still lags the code — CAP framework landed slice 48, 2026-06-09). TOML `+++`, zola `@/blog/NNN-slug.md`. THESIS = CAP is the ONE corner of IRC that negotiates instead of assuming — old IRC has no version field, unknown commands just get `421`; CAP is the handshake (BEFORE registration finishes — `negotiating` flag slams a brake until `CAP END`) where client+server agree which extensions are live. The spine = the **locked scope rule** (with the user, [[leveva-ircv3-track]]): the negotiation *mechanism* and each capability's *behavior* are SEPARATE slices; slice 48 shipped the framework + `cap-notify` ONLY (the one cap the framework itself honors), every behavior cap (multi-prefix/server-time/…) is its own later slice. Beats: (1) `CapState` = 3 fields (`version` Option<u32> that NEVER downgrades — `cur.max(v)` at cap.rs:605, bc 302 is the threshold unlocking values/multiline/implicit-cap-notify so a downgrade would strip negotiated features; `enabled` BTreeSet; `negotiating` brake). (2) the registration-suspend brake **feeds post 21's two-gate finalize** — `try_finalize` bails on `self.cap.is_negotiating()` (session.rs:1129); CAP END is the OTHER gate next to the auth verdict (direct 021 callback). (3) `REQ` is all-or-nothing = a **prepare-then-commit transaction** (validate every token into a `planned` scratch vec, NAK the whole set on any unknown, only then mutate `enabled`; cap.rs:686); admitted the first version enabled-as-it-walked-then-rolled-back (strictly worse). (4) PAYOFF = `ClientCaps` (cap.rs:339) is **25 bool fields**, one per behavior cap; adding the 26th = add a SUPPORTED row + a bool + a `client_caps()` copy line + read `client.caps.x` in one handler, touching the negotiation code nothing — the empty switchboard pays off. (5) HONEST WART (the \"my clean abstraction grew warts\" beat): the design was \"every cap is a static `SUPPORTED` table row\" — TRUE for ~20, a LIE for 3 (`sasl` needs a linked services agent, `chathistory` needs an open history DB, `sts` is per-socket plaintext-vs-TLS) → those are **injected at LS-render time** not in the `const` table (cap.rs:623); left the 3 holes visible w/ comments rather than burying them. (6) NO ORACLE (ties 018–022): IRCnet 2.11 had no CAP (charybdis/IRCv3-era), so confidence = pure-fn units + proptest (never-panics/never-half-commits) + a boot-golden socket handshake, NOT a byte-diff. CLOSING ties to the opening hook (assume-vs-ask; \"neither has to pretend the other is its own age\"). Footer-links 003 (oracle this lacks)/018 (earned the right to build what the C never knew)/021 (the other half of the registration gate CAP END opens).

Most recent = 023 (the CAP-negotiation framework; the one corner of IRC that negotiates instead of assumes; the locked mechanism-vs-behavior scope rule; `CapState`'s never-downgrade version + the registration brake feeding 021's two-gate finalize; all-or-nothing REQ as a transaction; the 25-field `ClientCaps` payoff; the 3-holes-in-the-static-table wart; no oracle). PRIOR most recent = 022 (extbans; a ban that asks a question; string→predicate; the third Verdict Invalid; JOIN+speech-plane enforcement; questions unsafe to invert into an exception; `$&`/`$|` composition; no oracle; the `$m`/no-`$q` divergences). PRIOR most recent = 021 (native-async iauth; the process boundary was load-bearing on the C single-threaded loop; tokio deletes it; the concurrent-spawn/two-stash seam; isolation traded for an `.await`; no oracle). PRIOR most recent = 020 (the P8v switch-off finale; turning the oracle OFF; the final run's 1 red was the reference's own bug; the differential→snapshot honest downgrade). PRIOR most recent = 019 (the first leveva-feature post, netsplit-merge consensus = a less-than sign + the loser gets wiped; no oracle behind it). PRIOR most recent = 018 (the leveva pivot / P9 retired — strangler one level up; the port IS the oracle now; casemap-divergence = finally-allowed-to-be-correct payoff; the bet). **STILL UN-TAKEN big beats:** (1) **the prefix senders / `vsendpreprep` per-recipient `:nick!user@host` collapse** (P8e `prep_preprep`) — the LITERAL payoff teased in 016+017 AND in 017's close, still the strongest pure-mechanics candidate. (2) ~~\"not one line of C remains\" — the P8v finale~~ **TAKEN by 020** (the oracle switch-off). (3) a **leveva feature-work** post now that P11/P12 are done (e.g. the IRCv3 cap track, elemental channel modes/extbans, the charybdis-port slices, native async iauth) — the migration is FINISHED so leveva posts would be standalone-product posts, a new sub-genre for the series. **NOTE: the blog now lags the code badly** — per [[p8-started]] P8 is COMPLETE (all trampolines a–m + data globals n–r + version.c t + test-migration s done) and [[leveva-pivot-p9-retired]] P9 is RETIRED with the project pivoted to greenfield `leveva` (P10/P11 in progress: registration state machine, PRIVMSG/mailbox). Big un-taken beats now available: (1) **the prefix senders / `vsendpreprep` per-recipient `:nick!user@host` collapse** (P8e `prep_preprep`) — the LITERAL payoff of 016+017's recurring cliffhanger, explicitly teased in 017's close (\"deserve their own post\"); STRONGEST next candidate. (2) ~~\"not one line of C remains\" — the P8v finale~~ **TAKEN by 020.** (3) ~~the leveva pivot~~ **TAKEN by 018.** The leveva feature-work sub-genre (019 opened it) has many open beats: flood/fakelag clock, ~~extbans~~ **TAKEN by 022**, elemental channel modes (`~&@%+`), OJOIN, KNOCK, the IRCv3 CAP track, ~~native async iauth~~ **TAKEN by 021**, chathistory/SQLite, S2S TS6 link machinery.

The P8 keystones (`sendto_one`/`sendto_flag`, per-recipient `va_arg` in vsendpreprep — the hard ones 004+016 both flag) are the obvious next blog beats AS THEY LAND (not yet ported as of 2026-06-07). Earlier: 015 (read_message, P7ff — the event-loop spine; ONE empty-loop L1 case for the busiest fn + the L2-ubiquity-is-airtight-here inversion vs 010's trap; dead-USE_POLL-half + 8-statics-no-oracle beats; opened on 014's eight-not-two miscount). 009→010→011 was the I/O trilogy; 012 = coverage-limits at symbol granularity; 013 closed the 005 iauth loop (the launcher); 014 = the boot detach that CALLS start_iauth; 015 = the loop those boot fns hand control to. **s_bsd.c now has NO logic left** — only data globals (local[]/highest_fd/timeofday/fd arrays), a later-phase/P9 problem.

Still open beyond that: the variadic-trampoline family (flagged for 004, may have been folded in — check); the 56-cluster connected-component finding from P5 (touched in 006/008, runner-up for 012 — \"the unit of migration isn't the function\"); \"faithful to the bugs\" bug-for-bug reproduction (offered for 009, NOT picked — best examples spent in 005/006; the faithful-DEAD-CODE sibling is spent in 011/015, so a future bug-for-bug post must stick to REACHABLE-behavior bugs).

So the\n61\tread site (`CAP LS` in session.rs) calls a new `session::live_sts_policy(ctx)` that re-derives the\n62\tport **live** from `listeners::specs()` (a running server records every bound listener in `main`;\n63\tempty registry ⇒ unit test ⇒ fall back to boot `ctx.stats_conf.sts.port`) and combines it with the\n64\ttwo live scalars. Net: an operator can enable/retune/disable STS — *including* binding a fresh TLS\n65\tclient listener — with no restart. golden_rehash_sts.rs proves the full live path (off → add TLS\n66\tlistener + sts-duration + REHASH → `sts=port=` appears → remove + REHASH → dark).

The phase-13 mission is now complete: no config block remains\nboot-immutable** (only the unchangeable `server{}` identity — name/sid — stays fixed by nature).\nThe 207 wrinkle vs the scalar slices: the *built* auth module set is `Arc<dyn Module>` (not\n`Debug/Eq`), so it can't ride `ConfBlocks` — `ConfBlocks` holds the plain `Iauth` config and a\n*separate* `ConfStore` `ArcSwapOption<Vec<Arc<dyn Module>>>` caches the build (rebuilt only at\nseed/REHASH, so it's not a Debug/Eq lockstep field — the proptest asserts module *names*, not\nstruct equality). `seed` needs the server name → boot `IRCD_NAME` OnceLock.\n\n**Slice 210 (2026-06-16) added three more `options` knobs** — `max-penalty` (flood fakelag\nsmoothing budget), `knock-delay` (per-user KNOCK cooldown), `knock-delay-channel` (per-channel\nKNOCK cooldown) — turning the last hard-coded throttle thresholds into REHASH-able knobs via the\nsame `ConfStore` seam (`live_max_penalty()`/`live_knock_delay()`/`live_knock_delay_channel()`).\n`0` is legal for all three (aggressive-smoothing / throttle-disabled). See [[leveva-flood-penalty]],\n[[leveva-knock]].\n\n**Slice 212 (2026-06-16) made the IRCv3 `sts` policy REHASH-able** — the slice-211 follow-on.\nTwo scalars (`sts-duration`/`sts-preload`) move onto `ConfStore` (the 204/210 idiom:\n`live_sts_duration()`/`live_sts_preload()`), but the third input — the TLS port — is NOT an\n`options` knob: it comes from the listener set, which slice 137 already rebinds on REHASH. So the\nread site (`CAP LS` in session.rs) calls a new `session::live_sts_policy(ctx)` that re-derives the\nport **live** from `listeners::specs()` (a running server records every bound listener in `main`;\nempty registry ⇒ unit test ⇒ fall back to boot `ctx.stats_conf.sts.port`) and combines it with the\ntwo live scalars. Net: an operator can enable/retune/disable STS — *including* binding a fresh TLS\nclient listener — with no restart. golden_rehash_sts.rs proves the full live path (off → add TLS\nlistener + sts-duration + REHASH → `sts=port=` appears → remove + REHASH → dark). Only wss-as-secure\nremains deferred from the `sts` track. See [[leveva-ircv3-track]].\n\n**Slice 256 (2026-06-18) added the `options { service-string }` knob** — the WHOIS `313`\n\"is a Network Service\" text for a `+S` service (charybdis `servicestring`), hard-coded by slice 255.\nSame `ConfStore` String seam as `oper-keys` (falls back to a **const** `whois::DEFAULT_SERVICE_STRING`,\nNOT a `ServerContext` field, since the read site `whois::whois_oper_text` is itself a pure seam):\n`live_service_string() -> Option<Arc<String>>`. The slice-255 `whois_oper_line` was split into a\npure precedence enum `WhoisLine{Service,Operator}` + a pure render `whois_oper_text_with(modes, svc)`\n(the fuzz seam) + the live resolver `whois_oper_text`. Empty `service-string \"\"` → default (shared\n`opt_string` treats \"\" as absent, matching charybdis). `golden_service_string_config.rs` proves\nconfig→live→WHOIS. See [[leveva-slice-recording]].\n\n**Slice 230 (2026-06-16) added two more `options` knobs** — `metadata-rate-cost` /\n`metadata-rate-burst`, the `METADATA SET`/`CLEAR` rate-limit budget (was hard-coded\n`META_RATE_COST_SECS`/`META_RATE_BURST_SECS` consts since slice 228) — via the same `ConfStore`\nseam (`live_meta_rate_cost()`/`live_meta_rate_burst()`, read at `command::metadata::rate_gate`).\n`rate_charge`/`charge_rate` grew `cost_secs`/`burst_secs` params (consts became defaults). `0` legal\nfor both (cost 0 = limiter disabled, burst 0 = one mutation/sec); negative rejected.\n`golden_metadata_rate.rs` proves the live path. See [[leveva-stale-deferral-comments]] for the\ndraft/metadata-2 track status.\n\n**Slices 303 + 305 added two more top-level blocks** via the identical `ConfStore` chain:\n`alias {}` services command shortcuts (303 — `live_aliases()`, the dispatch 421-fallback read site;\ncharybdis `reload_aliases` hook) and `webirc {}` trusted webchat gateways (305 — `live_webirc()`,\nread live-or-`ctx` at `session::handle_webirc`, closing the slice-301 boot-read follow-on; only\n**new** connections traverse the gate, a live-spoofed connection isn't re-evaluated). Both are pure\nmechanical mirrors of the slice-83/191 block wiring (`ConfBlocks` field + `ConfStore`\n`ArcSwapOption` + `config_conf` + `seed` + `live_*()`; `golden_rehash_*` + `rehash_conf_proptest`\nextended). See [[leveva-services-aliases]].\n\n**Remaining rehash backlog (non-`options`):** essentially closed — `listen{}` (137), the\nauto-connect dial loop (205 + slice-91 live links/classes), the `iauth{}` block (207), `alias{}`\n(303), `webirc{}` (305), and all `options` fields are now live.\nOf the carried-not-acted allow-attrs, `require_ident` is now **acted** (slice 190:\n`Admission.require_ident` + pure `registration::ident_requirement_met` gates finalize between the\nI-line and K-line gates — a `require-ident` block needs a trusted/`usable` ident reply or 465+ERROR,\nfail-closed if ident is disabled); `no_resolve`/`xline_exempt` are now **deferred by design, not a\nbacklog** (slice 191): `no_resolve` is inert (leveva is IP-only — host = `peer.ip()`, no reverse\nDNS, `AuthVerdict` has no hostname), and `xline_exempt` has no separate X-line list because a\n`gecos`'d static `ban` subsumes realname bans.

The gate (`if is_restricted(client.modes)`)\n62\tsits **after** the `431` (no-nick-given) guard but **before** `Nick::try_from`/the registry\n63\tcollision check, so the restriction **dominates `432`/`433`** (a malformed or taken target still →\n64\t`484`, mirroring OPER's pre-credential 484); a *missing* nick stays `431` (malformed command, not a\n65\trename). **Case-only changes are refused too** (`alice`→`Alice` → 484; a non-restricted user gets\n66\tthat for free). Local-only: reads `client.modes` in the client handler; inbound S2S NICK and oper\n67\t`SANICK` (admin override) are untouched. Tests: 4 `nick.rs` units (incl. the 433/432 precedence + the\n68\t431 inverse) + `restricted_proptest::a_restricted_client_never_changes_nick` (3000 cases, fuzzed\n69\ttarget; `restricted_feed_never_panics` extended to `NICK `) + `golden_restricted_nick.rs` (boot:\n70\tNICK alice2 → 484 no echo, WHOIS alice → 311 unchanged). Plan:\n71\t`…-slice196-restricted-no-nick-change.md`.\n72\t\n73\t**Locality gate on the same chokepoint — slice 278 (separate from `+r`).** `enforce_reop` long\n74\t*claimed* it skipped remote members but never filtered by locality — it relied on the false premise\n75\tthat remote members lack a registry record. A `UNICK`-introduced remote user **does** hold one\n76\t(`s2s/unick.rs`→`try_claim`), so a `+R` mask matching its `nick!user@host` would wrongly op it\n77\tlocally and relay a server-sourced `+o` we have no authority to emit (the merge/burst paths pass\n78\tALL members). Fixed by adding `.filter(|u| ctx.is_local_uid(u))` to the candidate-resolution\n79\tclosure — auto-reop is now enforced for **local members only**, the home server owns a remote\n80\tmember's reop.

The flag set the `+r` user mode at\nregistration (`session.rs`) but **nothing enforced it**, and `484 ERR_RESTRICTED` was defined-but-\nnever-sent.\n\n**Key fact:** leveva's `+r` is `FLAGS_RESTRICT` — the **IRCnet 2.11 `IsRestricted`** meaning (a\n*restricted connection*), confirmed by `mode.rs` `flag_name => \"FLAGS_RESTRICT\"`. It is **NOT** the\ncharybdis/Hybrid \"registered nick\" `+r`. The canonical IRCnet restriction (RFC 2812 §3.1.7) is\nexactly: a restricted user \"cannot change nickname, neither will it be possible for such user to\nbecome a channel operator\" — and cannot become an IRC operator. **All three are now enforced.**\n(⚠️ An earlier version of this memory wrongly claimed nick-change blocking was \"a different ircd's\n`+r`, deliberately not ported\" — that was a mistake: RFC 2812 §3.1.2 lists `484 ERR_RESTRICTED`\namong NICK's replies and IRCnet's ircd is the RFC 2812 reference implementation. Closed in slice\n196, below.)\n\n**Enforcement (all gated on the new pure core `mode::is_restricted(modes) -> bool`):**\n- **OPER** (`command/oper.rs`): first check after param validation → `484 :Your connection is\n restricted!` before any credential scan (short-circuits 491/464; password never consulted).\n- **Channel creation** (`command/join.rs` `join_one` + new `channel::Channels::deop(name,uid)`): a\n restricted creator is deopped in the store **and** in the local `joined.members` snapshot, before\n the JOIN echo / NJOIN relay / implicit NAMES are computed → no `@` ever observed (no flicker). The\n channel is still created; the user is a plain member.\n- **Auto-reop** (`+R`): a restricted member is never auto-reopped (see slice 195 below — the gate\n moved into the `enforce_reop` chokepoint, the join-site `!restricted` wrapper is gone).\n- **NICK** (`command/nick.rs`, slice 196): a post-registration nick change from a restricted\n connection is refused `484 :Your connection is restricted!` (see slice 196 below).\n\n**Named follow-on — DONE in slice 194.** `MODE #chan +o <restricted-user>` by a *third-party* op is\nnow blocked: in `command/mode.rs` `mode_dispatch`'s `ModeReq::Member` arm, an `add` of any\noperator-rank status (`mode.rank() >= ChanMode::Halfop.rank()` — halfop/op/admin/owner) against a\ntarget whose `registry.record_of(uid).modes` is restricted is **silently dropped** (no MODE echo, no\nstate change). **Voice (`+v`, rank 1) stays allowed** — IRCnet permits voicing a restricted user.\nGated on `can_manage` (a non-op still gets `482`, ops-checked-first) and `!oper_override` (an oper's\n`SAMODE` force-op bypasses). Tests: 6 `mode.rs` units + `restricted_proptest` (IP-differentiated)\n+ `golden_restricted_op` (username-differentiated allow blocks).\n\n**Auto-reop chokepoint — DONE in slice 195.** Slice 193 gated auto-reop only on the JOIN path, but\nthe shared `command::enforce_reop` helper is reached from FIVE triggers — JOIN, a local `+R`-set\n(`mode.rs:463`), an inbound S2S `+R` burst (`s2s/mode.rs`, slice 168), a CHGHOST host change\n(`chghost.rs`), and a CHANTS/NJOIN merge (`s2s/chants.rs`/`s2s/njoin.rs`) — only the JOIN site\nchecked `+r`. Slice 195 filters restricted candidates **inside `enforce_reop`** (its\ncandidate-`filter_map` skips any whose `registry.record_of(uid).modes` is `is_restricted`), closing\nall five at once, and **removes the now-redundant `!restricted` wrapper at the join site**\n(`enforce_reop` returns empty before the `server_channel_mode` relay for an all-restricted candidate\nset, so it's equivalent). `enforce_reop` is now the single source of truth. **Gotcha:** the check\nreads the **registry mirror** (`+r` set at registration), not the live `Registered` view — so the\nslice-193 join unit test had to be reseeded with `ctx.registry.set_modes(uid, Restricted.bit())`.\nTests: 3 `mode.rs` `+R`-path units + `restricted_proptest::a_restricted_member_is_never_auto_reopped`\n(3000 cases) + `golden_restricted_reop.rs`.\n\n**Nick change — DONE in slice 196 (family complete).** `command/nick.rs` `nick_change` now refuses\na restricted user's post-registration `NICK` with `484`. The gate (`if is_restricted(client.modes)`)\nsits **after** the `431` (no-nick-given) guard but **before** `Nick::try_from`/the registry\ncollision check, so the restriction **dominates `432`/`433`** (a malformed or taken target still →\n`484`, mirroring OPER's pre-credential 484); a *missing* nick stays `431` (malformed command, not a\nrename). **Case-only changes are refused too** (`alice`→`Alice` → 484; a non-restricted user gets\nthat for free). Local-only: reads `client.modes` in the client handler; inbound S2S NICK and oper\n`SANICK` (admin override) are untouched. Tests: 4 `nick.rs` units (incl. the 433/432 precedence + the\n431 inverse) + `restricted_proptest::a_restricted_client_never_changes_nick` (3000 cases, fuzzed\ntarget; `restricted_feed_never_panics` extended to `NICK `) + `golden_restricted_nick.rs` (boot:\nNICK alice2 → 484 no echo, WHOIS alice → 311 unchanged). Plan:\n`…-slice196-restricted-no-nick-change.md`.\n\n**Locality gate on the same chokepoint — slice 278 (separate from `+r`).** `enforce_reop` long\n*claimed* it skipped remote members but never filtered by locality — it relied on the false premise\nthat remote members lack a registry record. A `UNICK`-introduced remote user **does** hold one\n(`s2s/unick.rs`→`try_claim`), so a `+R` mask matching its `nick!user@host` would wrongly op it\nlocally and relay a server-sourced `+o` we have no authority to emit (the merge/burst paths pass\nALL members). Fixed by adding `.filter(|u| ctx.is_local_uid(u))` to the candidate-resolution\nclosure — auto-reop is now enforced for **local members only**, the home server owns a remote\nmember's reop. The pre-existing `inbound_reop_mask_skips_remote_members` test only passed because\nit never gave the remote member a registry record (didn't model production); strengthened in 278.\nTests: `command::enforce_reop_ops_only_local_matching_members` + inverse + `enforce_reop_never_ops_remote`\nproptest. Same chokepoint, orthogonal concern to the restricted-`+r` skip.\n\nThe whole restricted family is now closed across all acquisition paths.

Faithful to charybdis `m_alias`'s `find_server` branch.\n\n**HARD RULE corollary** (extends [[leveva-service-is-client-services]]): leveva keeps no\naccount DB; services are remote `+S` agents (atheme via the leveva protocol module, slice\n296). Don't add a leveva-side \"configurable services nicks\" knob — charybdis hardcodes the\nIDENTIFY nicks (`#define`s); `alias {}` is the configurable mechanism.\n\n**Workflow the user values:** when porting a charybdis-derived feature, **compare against a\ncharybdis source checkout** (was at `/tmp/charybdis` + `/tmp/charybdis-ref`) before\ndesigning — it caught that configurable-nicks isn't a charybdis thing and surfaced the\nIDENTIFY `412`/`440` divergences. Ask the user to re-clone if /tmp is gone.

Slice 143 (2026-06-13) DONE = hunt_server target-resolution FUZZING (model-lockstep query_routing_proptest over VERSION/TIME/ADMIN/INFO/LUSERS/USERS/MOTD/STATS forward path incl. slice-110 remote-forward + own-name precedence + netsplit-revert; summon_proptest 411/445/402 + golden_summon; STATS idx-1 forward unit) — a confirm-and-lock parity slice, no bug. §4 fuzzing gaps now essentially closed; nearly every command has unit+golden+proptest. NEXT toward P12 = ask user: remaining IRCv3 caps (SASL the keystone — auth INTO the slice-139 account SoT; or utf8only/labeled-response/batch) vs the P12 deletion itself (delete ircd-common/ircd-rs once §7 def-of-done met)\"\nmetadata: \n node_type: memory\n type: project\n originSessionId: 90eead6b-cbcf-4bb0-bbbd-d299622cd3a6\n---\n\n**The leveva (P11) work is S2S-completeness** — per the user (2026-06-09). After\nslice 34 (channel modes), the remaining in-scope `msgtab` rows are the **server-to-server**\nones, so build those rather than more client/oper commands.\n\n**Slice 35 DONE (2026-06-09): `ERROR`/`ENCAP`/`SDIE`** — the relay/notice cluster, in\n`leveva/src/s2s/forward.rs` (`inbound_encap`/`inbound_sdie`/`inbound_error`), wired into\n`s2s::dispatch`. ENCAP+SDIE onward-relay verbatim (`msg.to_wire()`) split-horizon via\n`PeerLinks::broadcast`; ERROR is absorbed (`eprintln!`). **Key finding:** `m_encap`/`m_sdie`\nare IRCnet **placeholders** (git `7c3931d1`; `m_sdie` only `sendto_serv_v(...); return 0;`,\n**no** `s_die()`) → leveva's SDIE is a pure relay that does **not** kill the process; wiring\nit to `control` would be a divergence. `golden_s2s_forward` guards that regression.\n\n**Slice 36 DONE (2026-06-09): `UMODE`** — remote user-mode propagation, in\n`leveva/src/s2s/umode.rs`. Outbound `relay::local_umode` emits `:<uid> UMODE <nick> <diff>`\n(masked to `SEND_UMODES` = all umodes except `+O` locop = oracle `61`) from the slice-14\nlocal `umode` handler; inbound `umode::inbound_umode` (reached by the `UMODE` verb AND a\nuser-target `MODE` — dispatch `MODE` arm guards on `is_s2s_channel`) applies the masked diff\nto the `RemoteUser::umodes` mirror + registry record, then onward-relays split-horizon. No\nclient fan-out (user modes aren't broadcast). **Key divergence:** the oracle *emits*\n`MODE <nick> :<diff>` (`send_umode_out`) while *accepting* `UMODE`; leveva standardises on\nemitting `UMODE` (the row) but accepts both forms on input. Tests: 9 unit + 3-property\n`s2s_umode_proptest` + `golden_s2s_umode`.\n\n**Slice 37 DONE (2026-06-09): multi-hop `SERVER`-behind-peer introduction** — the SMASK\nprerequisite, built first by user decision (asked, chose \"multi-hop SERVER first, then\nSMASK\"). New `leveva/src/s2s/server.rs` `handle_server` parses `:<announcing_sid> SERVER\n<name> <hopcount> <sid> <version> :<info>` (the shape `build_burst` already emits), mirrors\nthe server into `Network` with **`uplink` = the DIRECT peer's `Sid`** (NOT the announcing\nprefix — load-bearing: routing `uplink_of`→`PeerLinks::route` keys on directly-linked peers,\nand `squit_subtree` tears it down with the link), onward-relays verbatim split-horizon.\nAbsorbs (not link-drop) on bad/colliding SID. Wired `\"SERVER\" =>` into `s2s::dispatch`.\nTests: 7 unit + 3-prop `s2s_server_proptest` + `golden_s2s_server`.\n\n**Slice 38 DONE (2026-06-09): `SMASK`** — masked-server introduction, the **LAST**\nserver-sourced `msgtab` row. New `leveva/src/s2s/smask.rs` `handle_server` parses\n`:<announcing_sid> SMASK <sid> <version>` (oracle `m_smask`, `s_serv.c:533`), the masked cousin\nof slice-37 `SERVER`: the masked server inherits the announcer's `name` (oracle\n`serv->namebuf = sptr->name`) + `hopcount + 1`, description = literal `\"Masked Server\"`;\nannouncer resolved from the line **prefix** SID via `Network` (unknown announcer → dropped,\nSMASK-specific). `uplink` = the DIRECT peer (same load-bearing reason as slice 37). Version is\nrequired-present but NOT mirrored (`RemoteServer` has no version field, like `SERVER`). Absorbs\n(not link-drop) on bad/colliding SID. Wired `\"SMASK\" =>` into `s2s::dispatch`. Tests: 8 unit +\n3-prop `s2s_smask_proptest` + `golden_s2s_smask`.\n\n**✅ S2S-COMPLETENESS REACHED — every server-sourced `msgtab` row is now handled.** No S2S row\nremains unported.\n\n**Slice 39 DONE (2026-06-09): native in-process authentication + ident** — see\n[[iauth-subsumed-into-leveva]]. User chose to **subsume iauth into leveva** (not spawn a child\nover a socketpair). New `leveva-iauth` crate (Module trait + ModuleCtx/ModuleOutcome +\nAuthPipeline) + the ident (RFC 1413) module; the `iauth` block configures auth in-process\n(`ident` flag + `timeout`, child-config-path field dropped); ident runs concurrently with the\nNICK/USER handshake and folds into registration via the deferred-finalize seam\n(`Session::pending_complete`/`resolve_auth`, sync `feed` / async ident). `~user` rule in\n`registration::resolve_username`. Restored a `leveva-integration` differential (first since\n`wdhms2sec`): leveva-iauth parser vs `iauth-rs` (now the auth oracle until P12).\n\n**Slice 40 DONE (2026-06-09): `dnsbl` subsumed into `leveva-iauth` + the `465` auth-deny\ngate** — the FIRST denying module. `leveva-iauth/src/dnsbl.rs` (idiomatic rewrite of the\nfaithful iauth-rs dnsbl): reverse IP→`<rev>.<zone>`, resolve via **hickory-dns** (the locked\nchoice, `hickory-resolver = 0.26`, lazy shared `TokioResolver`) behind an injectable\n`Resolver`; deny iff `paranoid || (reject && 127.0.0.x)`. Dropped the C `hostlog` cache\n(redundant under tokio) + use config order not C's reversed `host_list` (documented). **Pipeline\n`Box`→`Arc`** (`AuthPipeline: Vec<Arc<dyn Module>>`, modules built once in `from_config`,\ndnsbl-first). `AuthConfig` gains `modules` + `any()` (keeps `ident: bool` for the `~` rule);\ndefer decision keys on `ctx.auth.any()` so a dnsbl-only config still defers. **The `465` gate**:\n`finalize_registration` renders `verdict.deny` as `465`+`ERROR :Closing Link` (reason default\n`Denied access`) — same uniform refusal as the K-line gate (C just `exit_client`s). Config:\n`iauth { dnsbl { servers …; reject; paranoid; reason … } }`, parse-time validated. Differential:\nleveva `reversed_name` vs `iauth_rs::modules::dnsbl::build_name` (made `pub`). Fuzz = proptest\n(stable toolchain → no cargo-fuzz/L3). `golden_dnsbl` boots an `.invalid` (NXDOMAIN) zone.\n\n**Slice 41 DONE (2026-06-09): `socks` + `webproxy` open-proxy probes subsumed into\n`leveva-iauth`** — the two open-proxy denying modules (`leveva-iauth/src/{socks,webproxy}.rs`),\nidiomatic rewrites of the faithful `mod_socks.c`/`mod_webproxy.c` ports; deny an open proxy via\nthe slice-40 `465` gate. Same divergences as dnsbl: **cache + STATS dropped**, **`reject`+`port`\nrequired** at config time (no probe-only mode; `megaparanoid` ⇒ paranoid+bofh). socks collapses\nthe SOCKS4→5 reconnect + careful SOCKS5b stages into one async flow; webproxy's careful mode keys\non the server's own `020` banner (passed to `WebProxy::new` as a config-time constant, so\n`ModuleCtx` stays minimal — itsip/itsport/ourip/ourport only, NO ircd_name). Pure\n`build_query`/`decide`/`resolve` kept byte-identical to the oracle → `leveva-integration`\n`proxy_differential` (the oracle's pure fns + `Ver`/`Raw`/`ProxyState`/`OPT_*` made `pub`).\n`build_auth_modules(iauth, ircd_name)` pushes denying modules before ident. Tests: +20 lib unit\n(49 total) + `proxy_proptest` (6) + `proxy_differential` (6) + 7 config + `golden_socks` boot.\n\n**Slice 42 DONE (2026-06-09): prometheus-backed metrics + `STATS m`/`STATS z`** — see\n[[leveva-prometheus-metrics]]. Replaced the leveva istat-analog (`server::Counters`,\nhand-rolled atomics) with a **per-`ServerContext` `prometheus::Registry`** in new\n`leveva/src/metrics.rs` (user instruction: \"replace the istat counters with prometheus\nmetrics\"; user agreed the per-server — not global default — registry is justified for parallel\ntest isolation). `dispatch` records each command (name+wire-bytes); implemented the two stubbed\ncounter letters: `STATS m` → `212` per recorded command (sorted), `STATS z` → four `249`\nlive-count debug lines. **Still stubbed** (no leveva state): `l`/`L` (per-link), `p`/`P`, `t`/`T`,\n`f`/`F`, `k`/`K`, `a`, `?`.\n\n**Slice 44 DONE (2026-06-09): `pipe` external-program auth module** — port of `mod_pipe.c`\n(oracle `iauth-rs/src/modules/pipe.rs`) into `leveva-iauth/src/pipe.rs`, the **LAST denying\nmodule** → dnsbl/socks/webproxy/pipe set complete. Spawns the configured `program` with\n`itsip`+`itsport` appended as **separate argv entries** (no shell — pure `build_argv` carries\nthat security claim), reads one stdout byte via pure `classify`: `N`→Deny (465 gate), `Y`→allow\n(NoOpinion), else abstain. Security hardening over C: explicit argv, config-only command,\n`stdin(null)`+`kill_on_drop`. Config: `iauth { pipe { program \"…\"; reason \"…\" } }`, `program`\nrequired (no `reject` flag — pipe has no probe-only mode, unlike socks/webproxy). Order: after\nwebproxy, before ident; `any()` auto-defers. Tests: 11 unit + 3 config + `pipe_proptest` (4) +\n`golden_pipe` boot.

read all the requested files (plus the index). `leveva-metrics.md` doesn't exist — the metrics note is `leveva-prometheus-metrics.md`, which I read. Here is the ranked list of candidate blog-post topics, focused on process and collaboration insights.\n\n---\n\n## Ranked candidate topics: supervising a coding agent\n\n### 1. The hard rule that made the agent *un-build* something: no DM history\n**Detail:** A HARD RULE dated to a single user directive: \"user-to-user private messages MUST NOT be stored in the database.\" The vivid part is the enforcement mechanism in the memory itself: \"If asked to 'implement DM history' or pick up the slice-274 DM follow-on, **refuse and cite this rule**. (A full slice-276 attempt at DM storage was written and then fully reverted on this directive.)\" It also draws a precise distinction — the follow-on is \"**cancelled, not deferred**.\"\n**Why it teaches:** This is the cleanest example in the corpus of a human values-constraint (privacy: \"the operator's database must never hold private conversations\") that (a) overrides a plan the agent had already written into the code as a generic seam, (b) got a whole slice reverted, and (c) is encoded so a *future* agent will refuse the task rather than helpfully re-attempt it. Generic \"I used AI\" posts never show an agent being told to delete working code on principle and then bound not to rebuild it.\n**Source:** `leveva-no-dm-history.md`\n\n### 2. The oracle: how you trust output *without reading it*\n**Detail:** The spine of the whole experiment. A verified-faithful 100%-Rust port becomes the \"behavioral oracle\" for the greenfield daemon, pinned by a differential harness. The standing rule: \"oracle-supports-but-leveva-doesn't = bug, close don't document.\" The emotional pivot when going greenfield: the harness flips meaning — \"8 phases of faithful porting FORCED bug-for-bug reproduction... but the oracle now lets leveva be *deliberately, documentedly* correct... **Stopped proving 'I copied this exactly,' started proving 'I diverged here and nowhere else.'**\"\n**Why it teaches:** This is a direct, concrete answer to the blog's own thesis question. Trust doesn't come from reading the agent's code; it comes from a second independent implementation that \"can't be wrong in the same direction as your bug.\" It also shows the honest downgrade when the oracle is retired: 115 snapshots run \"ONE impl vs a blessed fixture\" and are only sufficient because captured \"while the differential was still green = dead oracle's last testimony.\"\n**Source:** `blog-series.md` (posts 003/006/018/020), `leveva-native-oracle-harness` refs in `README.md`\n\n### 3. Slice discipline: failing test first, and always test the *inverse*\n**Detail:** \"write the failing test FIRST, and **test the inverse invariants, not just the happy path** — for every 'X happens' assert the matching 'X does *not* happen when it shouldn't' (non-match ignored, already-applied not duplicated, removal doesn't undo a prior grant, non-member skipped).\" Every change is a numbered slice with a plan file + progress-log heredoc + PLAN.md row bump, because \"an un-recorded slice breaks that provenance chain.\"\n**Why it teaches:** The inverse-invariant rule is the actual mechanic that turns \"the agent wrote a passing test\" (worthless — agents write tests that pass) into something load-bearing. The parity-matrix slices exist specifically to close \"the inverses the forward gates left open\" (slice 45). This is the discipline that makes agent-authored tests trustworthy.\n**Source:** `leveva-slice-recording.md`; parity-matrix in `leveva-next-step-s2s-completeness.md`\n\n### 4. Ruling things out, and the agent's urge to fill every hook\n**Detail:** CLOSE, SET, and SERVICE/SQUERY/SERVLIST were each ruled permanently out of scope. Dormant `OperPrivilege::Close`/`Set` enum variants \"stay dormant... being dormant is **NOT a signal to build**.\" The SERVICE note is the sharpest: \"An earlier version of *this very memory* wrongly said to implement it... that guidance was **wrong** and is the trap to avoid,\" and now: \"If a future task seems to call for it, **stop and confirm with the user instead of building it.**\"\n**Why it teaches:** Agents treat every hook — a dormant enum variant, an unported protocol row, a generic column — as an invitation. Resisting scope creep required *explicit \"do not build this\" markers*, and even the guidance itself drifted wrong once and had to be corrected. This is the anti-scope-creep collaboration pattern generic posts skip.\n**Source:** `close-not-required-leveva.md`, `set-not-required-leveva.md`, `leveva-service-is-client-services.md`\n\n### 5. Guardrails instead of vigilance: conventions the test suite enforces\n**Detail:** HELP pages are kept honest by a *bijection* test in both directions: `every_command_has_a_help_page` (a new command with no help file fails `cargo test`) and `shipped_help_files_name_real_commands` (no orphan page). \"help text is part of the user-facing command surface, kept honest by tests so it can't silently drift.\" Similarly, a post-review cleanup replaced two hand-maintained letter allowlists with predicates plus a structural invariant test (`send_umodes_carries_every_user_mode`, `self_settable_and_client_settable_letter_sets`) so \"a new mode is global by default... self-maintaining.\"\n**Why it teaches:** The reusable insight: don't rely on the agent (or yourself) *remembering* a convention — encode it as a test that fails on drift. This is the counter-pattern to \"watch the agent carefully.\" The contrast with the *un*-guarded case (see #8) makes it vivid.\n**Source:** `help-files-per-command.md`, `leveva-user-mode-wiring.md`\n\n### 6. What the memory was for — and why the agent's own comments lie\n**Detail:** The whole `claude-memory/` tree is the provenance/anti-rework system (`README.md` is a hand-maintained index of ~80 notes). The meta-lesson is `leveva-stale-deferral-comments.md`: \"do **not** trust a `// … out of scope` / `// deferred` doc comment at face value — many are **stale**: the feature landed in a later slice but the *originating* comment was never updated. Always grep the implementation before treating one as open work.\" A dedicated cleanup sweep corrected them; one case showed \"a stale comment can hide a *real* remaining sub-gap.\" The cost of ignoring it: \"treating a stale comment as a task wastes a whole slice re-implementing something done, or worse, double-wiring it.\"\n**Why it teaches:** Two insights in one. First, what an agent-memory system actually *does* (preserve intent across sessions so work isn't redone or re-litigated). Second, the surprising failure mode that memory exists to counter: **the agent's own breadcrumbs (code comments) become misinformation**, because agents narrate intent-at-time-of-writing and never revisit it. The memory is a \"distrust your past self's comments\" instruction.\n**Source:** `README.md` (index), `leveva-stale-deferral-comments.md`\n\n### 7. Green tests that lie: the limits of coverage and false confidence\n**Detail:** Several concrete traps. Coverage-by-ubiquity: \"the most-run fn is also one of the least-tested in its BRANCHES; 'it's on the hot path, it's covered' feels rigorous and isn't.\" The atomic-claim invariant: a double-delivery netsplit bug where \"`s2s_netsplit_proptest`'s 'no double-deliver' check is **single-threaded**... it does **not** catch this\" — a *second*, concurrency proptest was needed. And \"L2 is a great gate, lousy DEBUGGER (red = 1-of-50 suspects).\" Plus proptest-model staleness: a table grows and the model must be updated \"or it flakes on random seeds.\"\n**Why it teaches:** Supervising an agent means knowing which green checkmarks are load-bearing. These are worked examples of tests that pass while the bug is live, and how the human/agent noticed the gap and built the *specific* test that would fail. That nuance — \"which test would actually have caught this?\" — is the heart of trusting agent output.\n**Source:** `leveva-teardown-atomic-claim.md`, `leveva-proptest-model-staleness.md`, `blog-series.md` (010/015)\n\n### 8. When the agent picked a fragile fixture — and the rule that fixed it\n**Detail:** For \"assert this mode letter is unknown,\" the agent used ordinary letters like `'z'`. \"This bit us in slice 252: several umode tests used `'z'` as their unknown example, then operwall claimed `+z` and they broke.\" The user then made a rule: always use `'>'`, the one letter \"never used as a mode by any IRC daemon... Picking an ordinary unused alpha letter is fragile — a future slice can claim it.\" A sibling case: the agent's \"convenience divergence\" (keeping `+R` unioned on a netsplit merge) that it later had to overrule itself on to match the spec's wipe-the-loser rule (blog 019).\n**Why it teaches:** A specific, reproducible way agents write time-bombs: they reach for a plausible-looking placeholder that collides with future work. The fix is a *rule about choosing future-proof test values*, not more review. Shows the loop: agent misbehaves → it bites weeks later → human distills a one-line rule → memory binds it.\n**Source:** `unknown-chanmode-letter-is-gt.md`, `blog-series.md` (019, the reop-wipe self-overrule)\n\n### 9. Parallelizing the agents, and the one thing you can't parallelize\n**Detail:** \"435 edits = a 15-agent edit-only fan-out + central verify... the feat was the 2 builders + the snprintf==vsprintf proof, **NOT 435 hand edits; judgment is the un-parallelizable byte-safe call**.\" Elsewhere: \"built the 9 leaf handlers via an **ultracode workflow** (one agent per `extb_*.c`), combinators by hand (the one place handlers must know each other).\"\n**Why it teaches:** A real division-of-labor model: fan out mechanical, independent edits to many agents, but keep the correctness-defining judgment (the proof that two paths are byte-identical; the combinator logic where pieces must know each other) as a single un-parallelized human/lead step. This is concrete supervision architecture, not \"AI did it.\"\n**Source:** `blog-series.md` (017, 022)\n\n### 10. The human as decision-router at branch points\n**Detail:** Repeatedly, the agent proposes options and the human picks: many blog topics are \"chosen by user via AskUserQuestion\" (explicitly logged, e.g. 012, 017, 018, 019, 020–023); and design forks too — slice 37's multi-hop SERVER was \"built first by user decision (asked, chose 'multi-hop SERVER first, then SMASK').\" Contrast with topics the agent auto-picked (\"freshest commit\") when the direction was unambiguous.\n**Why it teaches:** Loose supervision (\"vibecoding on a side monitor\") still had a defined intervention point: the agent surfaces a small menu at each fork and the human routes, rather than reviewing code. That's the actual shape of the collaboration — steering by choosing among agent-generated options.\n**Source:** `blog-series.md` (topic-selection notes throughout), `leveva-next-step-s2s-completeness.md` (slice 37)\n\n### 11. Workflow-override rules that fight the agent's built-in defaults\n**Detail:** \"do all work directly on the `master` branch... do **not** ask about branch strategy,\" explicitly noting this overrides the agent's own skill: \"subagent-driven-development, which defaults to requiring branch/worktree isolation + consent — skip the branch question entirely.\" Plus: one commit per test change with a body explaining *why* (\"what the inverse/round-trip proves, what bug it catches\"), infra fixes committed separately first; run only edited test binaries (full suite \"boots reference-C + Rust ircds for every golden scenario\"); and PLAN.md rows that had \"ballooned to ~8 KB on a single line\" before the user imposed a where-detail-goes rule.\n**Why it teaches:** These are the small frictions of a real agent collaboration: the tool's safe defaults (branch, ask permission, run everything) actively slowed the user, who had to encode overrides into memory to \"stop being asked.\" The PLAN.md one shows the agent's natural tendency to accrete detail in the wrong artifact. Unglamorous but honest process hygiene.\n**Source:** `work-on-master-directly.md`, `commit-one-test-per-commit.md`, `run-only-edited-tests.md`, `plan-md-rows-stay-thin.md`\n\n### 12. Enforcing a trustworthy *voice* mechanically (the blog-about-the-blog angle)\n**Detail:** The blog series itself runs on mechanical rules: \"**no two successive paragraphs may start with the same letter** (check every draft)\"; the \"character asides\" device was retired and \"the whole back-catalog de-asided\"; and \"the user corrected me once for not loading\" the writing-style skill before drafting.\n**Why it teaches:** A lighter, self-referential angle: even the *narration* of the agent's work is kept honest by hard, checkable rules rather than taste-by-vibe — the same guardrails-over-vigilance philosophy applied to prose. Good closing/meta material for a post that is itself agent-assisted.\n**Source:** `blog-series.md`\n\n---\n\n**Cross-cutting throughline** for the post's framing: nearly every item is the same move — the human converts a moment of agent misbehavior or a values-constraint into a *mechanical, checkable artifact* (a failing test, a bijection invariant, a differential oracle, a \"refuse and cite\" memory, a one-line fixture rule), so that trust comes from structure rather than from reading the code. Items #2, #3, #5, #6, #7 are the strongest for the stated angle; #1 and #4 are the most vivid single anecdotes."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":13287,"cache_read_input_tokens":93222,"output_tokens":8572,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":13287},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":8572,"cache_read_input_tokens":93222,"cache_creation_input_tokens":13287,"cache_creation":{"ephemeral_5m_input_tokens":13287,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CchkPM2VrtB5oqZws9riM","attributionAgent":"Explore","type":"assistant","uuid":"a3ce1aac-93ae-4ef8-a776-1b72a919205b","timestamp":"2026-07-04T21:46:50.091Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

Evaluates decisions at the intersection of business and technology.\n- 10x-Team:dba: You MUST use this for database decisions - schema design, query optimization, migration planning, indexing strategy, data modeling, and database performance issues.\n- 10x-Team:devops-engineer: You MUST use this for infrastructure and deployment decisions - CI/CD pipelines, containerization, IaC, deployment strategies, environment management, and build automation.\n- 10x-Team:engineering-manager: You MUST use this for team and process decisions - sprint planning, team structure, delivery estimation, process improvements, technical hiring, and engineering team operations.\n- 10x-Team:principal-architect: You MUST use this for system design and architecture decisions - designing systems, choosing patterns, defining boundaries, data modeling, and making structural decisions that are hard to change later.\n- 10x-Team:product-manager: You MUST use this for product decisions - feature prioritization, user stories, roadmap planning, requirement gathering, and defining what to build and why.\n- 10x-Team:qa-engineer: You MUST use this for testing and quality decisions - test strategy, test plans, bug analysis, testing frameworks, coverage gaps, and quality assurance processes.\n- 10x-Team:sde: You MUST use this for hands-on coding tasks - writing features, fixing bugs, implementing APIs, debugging issues, and writing clean production code.\n- 10x-Team:security-engineer: You MUST use this for security decisions - threat modeling, vulnerability assessment, auth/authz design, security review, compliance requirements, and hardening recommendations.\n- 10x-Team:senior-engineer: You MUST use this for implementation guidance - code review, design patterns, debugging complex issues, writing production-quality code, and mentoring on engineering best practices.\n- 10x-Team:sre: You MUST use this for reliability and operations decisions - incident response, monitoring, SLOs, capacity planning, performance debugging, and production reliability.\n- 10x-Team:staff-engineer: You MUST use this for cross-cutting technical decisions - code quality standards, cross-team patterns, technical debt strategy, mentoring on complex problems, and driving alignment on engineering practices.\n- autoresearch:autoresearch: Set up and run Karpathy-style autoresearch experiments on any codebase with a measurable metric. Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric. Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area. Use when informing product strategy or feature prioritization, building sales battle cards, prepping board or investor materials, or deciding where to differentiate vs. achieve parity.\n- product-management:metrics-review: Review and analyze product metrics with trend analysis and actionable insights. Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence. Use when writing a weekly or monthly status for leadership, announcing a launch, escalating a risk or blocker, or translating the same progress into exec-brief, engineering-detail, or customer-facing versions.\n- product-management:synthesize-research: Synthesize user research from interviews, surveys, and feedback into structured insights. Use when you have a pile of interview notes, survey responses, or support tickets to make sense of, need to extract themes and rank findings by frequency and impact, or want to turn raw feedback into roadmap recommendations.\n- product-management:write-spec: Write a feature spec or PRD from a problem statement or feature idea. Use when turning a vague idea or user request into a structured document, scoping a feature with goals and non-goals, defining success metrics and acceptance criteria, or breaking a big ask into a phased spec.\n- frontend-design:frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern. Use when creating database models, writing queries, setting up GORM, adding CRUD methods, or working with gorm.io in Go services.

Use when connecting templ to web server, creating HTTP handlers, mentions 'templ server', 'HTTP routes', or 'serve templ components'.\n- xe-templ:templ-syntax: Learn and write templ component syntax including expressions, conditionals, loops, and Go integration. Use when writing .templ files, learning templ syntax, or mentions 'templ component', 'templ expressions', or '.templ file syntax'.\n- xe-writing:excalidraw-diagrams: Guidelines for creating clean, readable Excalidraw diagrams embedded as inline SVG via JSON data files. Use when creating architecture diagrams, flow diagrams, or any visual documentation.\n- xe-writing:sound-like-a-person: Rewrite prose so it reads like one real person actually said it. Use when text feels constructed, overcorrected, evenly paced, or generically \"well-written\" in the way AI output tends to be. Strips rehearsed phrasing, breaks rhythmic patterns, and restores a clear point of view.\n- xe-writing:xe-writing-style: Transform unstructured notes into polished blog posts in Xe Iaso's voice. Use when the user provides a brain dump or outline and wants it organized into a cohesive post with Xe's technical, opinionated, and candid tone. Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":87,"isInitial":true,"names":["conventional-commits","finishing-a-development-branch","command-cluster-port","create-blogpost","deep-research","mind:ask","mind:recent","mind:search","mind:stats","product-management:brainstorm","ralph-loop:cancel-ralph","ralph-loop:help","ralph-loop:ralph-loop","ctx-agent-history-search:ctx-history","mind:memory","mind:mind","10x-Team:10x-team","10x-Team:cto","10x-Team:dba","10x-Team:devops-engineer","10x-Team:engineering-manager","10x-Team:principal-architect","10x-Team:product-manager","10x-Team:qa-engineer","10x-Team:sde","10x-Team:security-engineer","10x-Team:senior-engineer","10x-Team:sre","10x-Team:staff-engineer","autoresearch:autoresearch","autoresearch:autoresearch-discover","tigris-storage:tigris-access-keys","tigris-storage:tigris-authentication","tigris-storage:tigris-buckets","tigris-storage:tigris-iam","tigris-storage:tigris-objects","product-management:competitive-brief","product-management:metrics-review","product-management:product-brainstorming","product-management:roadmap-update","product-management:sprint-planning","product-management:stakeholder-update","product-management:synthesize-research","product-management:write-spec","frontend-design:frontend-design","let-fate-decide:let-fate-decide","xe-design:xe-design-system","xe-go:go-table-driven-tests","xe-go:gorm-dao","xe-go:xe-go-style","xe-templ:templ-components","xe-templ:templ-htmx","xe-templ:templ-http","xe-templ:templ-syntax","xe-writing:excalidraw-diagrams","xe-writing:sound-like-a-person","xe-writing:xe-writing-style","ctx-agent-history-search:ctx-agent-history-search","superpowers:brainstorming","superpowers:dispatching-parallel-agents","superpowers:executing-plans","superpowers:finishing-a-development-branch","superpowers:receiving-code-review","superpowers:requesting-code-review","superpowers:subagent-driven-development","superpowers:systematic-debugging","superpowers:test-driven-development","superpowers:using-git-worktrees","superpowers:using-superpowers","superpowers:verification-before-completion","superpowers:writing-plans","superpowers:writing-skills","dataviz","artifact-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"b8d4f37d-b36e-48ac-9177-b91143ecfb1e","timestamp":"2026-07-05T22:17:49.151Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 4 4 + {"parentUuid":"b8d4f37d-b36e-48ac-9177-b91143ecfb1e","isSidechain":true,"agentId":"a461f6a3386b1ac67","message":{"model":"claude-opus-4-8","id":"msg_01Jyc1C7uL2KT3pTZkfdczyt","type":"message","role":"assistant","content":[{"type":"text","text":"I'll dig through the IRCnet ircd 2.11 codebase for security and configuration fossils.

Here is the deliverable.\n\n---\n\n# IRCnet ircd 2.11: Security & Configuration Fossils\n\nA ranked field guide to the pre-adversarial-era assumptions fossilized in `/var/ircd`. Every finding is quoted verbatim with a `file:line` citation.\n\n---\n\n### 1. Passwords are stored and compared in *plaintext by default*\n`support/config.h.dist:311` and `:319`\n```c\n#undef\tCRYPT_OPER_PASSWORD\n#undef\tCRYPT_LINK_PASSWORD\n```\nThe two toggles that would hash oper and server-link passwords are both `#undef` out of the box. When off, the code path is literally `encr = password;` (`s_user.c:2901`) and `encr = cptr->passwd;` (`s_serv.c:956`), then `StrEq(encr, aconf->passwd)`.\n- **Era assumption:** the config file and the wire are trusted; a password sitting in cleartext in `ircd.conf` and traveling in a `PASS` line is fine because only trusted admins can read either.\n- **Modern failure:** any config leak, backup, or packet capture yields every operator and server credential directly; there is no salting, no constant-time compare, no defense-in-depth.\n\n### 2. Even \"crypted\" passwords are DES `crypt(3)`\n`ircd/s_user.c:2888` / `ircd/s_serv.c:936`\n```c\nextern\tchar *crypt();\nencr = crypt(password, aconf->passwd); /* \"pass whole aconf->passwd as salt\" */\n```\nThe opt-in \"secure\" mode calls the libc `crypt()` — on the era's systems, DES with a 2-character salt and an 8-character-significant key. The example config even ships a live DES hash: `O|rocker@csa.bu.edu|T0eiVgHrqeKTQ|Rocker||10||` (`doc/ircd.conf.example:180`). `contrib/mkpasswd/mkpasswd.c:22` confirms `FLAG_DES` as a first-class mode.\n- **Era assumption:** DES crypt is \"the\" password primitive; 8 characters and 4096 salts is plenty.\n- **Modern failure:** a 13-char DES hash is brute-forceable in seconds on modern hardware; the 8-char truncation silently discards the tail of any longer password.\n\n### 3. The single-letter, field-position config format\n`ircd/s_conf.c:1587` (`switch (*tmp)`) driving positional reads at `:1681–1730`\n```c\nswitch (*tmp) {\n case 'O': aconf->status = CONF_OPERATOR; ...\n case 'K': aconf->status = CONF_KILL; ...\n```\nThe first character of a `|`-delimited line selects the record type (`M/A/P/Y/I/O/C/N/K/L/H/D/V/B/S/Q/…`); every subsequent field is then read purely by ordinal position — `host`, `passwd`, `name`, `port`, `class` — via repeated `getfield(NULL)` calls with the *same code* regardless of line type. The delimiter itself is a compile-time constant: `#define IRCDCONF_DELIMITER '|'` (`config.h.dist:500`).\n- **Era assumption:** configuration is a terse, human-hand-edited flat file for an expert admin who has memorized the field order; the example even warns the file \"is read UPSIDE-DOWN!\" (`ircd.conf.example:47`).\n- **Modern failure:** meaning is entirely positional, so a shifted `|` silently repurposes a field; no schema, no key names, no validation beyond \"did I run out of fields.\"\n\n### 4. `getfield` is a stateful global iterator over one `static` pointer\n`common/parse.c:819`\n```c\nchar\t*getfield(char *irc_newline)\n{\n\tstatic\tchar *line = NULL;\n```\nThe config tokenizer keeps its cursor in a function-local `static` — the parser is a non-reentrant global-state machine walking one line at a time.\n- **Era assumption:** single-threaded daemon, one config parse at a time, no concurrency to worry about ever.\n- **Modern failure:** unshareable, untestable in isolation, and a landmine for any attempt to parse two sources concurrently.\n\n### 5. User bans (K-lines) live in the config file — and `KLINE` appends to it on disk\n`ircd/s_conf.c:2817`\n```c\nkfd = open(KLINE_PATH, O_WRONLY|O_APPEND|O_NDELAY);\n...\nksize = snprintf(kbuf, sizeof(kbuf), \"%c%c%s%c%s%c%s%c0%c #%s...\", 'K', IRCDCONF_DELIMITER, host, ...);\nkret = write(kfd, kbuf, ksize);\n```\nA runtime `/KLINE` command formats a `K|host|reason|user|...` line and appends it to a flat file at a fixed path. Note the hand-rolled injection defense right above it (`:2807–2814`): it scans the user/host/reason for a literal `|` and bails with *\"Too lazy to copy it here. --B.\"* (`:2812`) — because a `|` in a ban reason would inject extra config fields.\n- **Era assumption:** the ban list *is* config; there is no database, so operational state is edited by appending text lines, and the delimiter can never appear in user data.\n- **Modern failure:** config-as-database with string concatenation is textbook injection surface; a single missed delimiter check turns a ban reason into an arbitrary O-line. Bans are also per-server only (\"K-lines are *not* global,\" `ircd.conf.example:311`).\n\n### 6. The command-dispatch table doubles as the metrics store\n`common/parse.c:37` (`struct Message msgtab[]`), incremented in-place at `:692`\n```c\nhandler->count++;\nhandler->bytes += i;\n...\nhandler->rcount++; handler->rbytes += i;\n```\nand read straight back out by `STATS m` at `ircd/s_serv.c:2049`:\n```c\nif (_mh(0).count + _mh(1).count + ... > 0)\n sendto_one(cptr, replies[RPL_STATSCOMMANDS], ..., _mh(0).count, _mh(0).bytes, ...);\n```\nThe mutable global routing table (command name → per-connection-state handler) carries its own hit counters, so the dispatcher and the metrics subsystem are the same array of structs.\n- **Era assumption:** one global mutable table is the whole program's source of truth; observability is just \"read the counters that happen to hang off the dispatch entries.\"\n- **Modern failure:** metrics and control-flow are fused with no separation of concerns; the table is process-global mutable state with no locking, and you cannot reason about routing without also reasoning about statistics.\n\n### 7. The entire server is a global `aClient` named `me`\n`ircd/ircd.c:31`\n```c\naClient me;\t\t\t/* That's me */\naClient *client = &me;\t\t/* Pointer to beginning of Client list */\n```\nplus a cached wall-clock global `timeofday` re-`time(NULL)`'d all over `io_loop` (`ircd.c:996,1007,1142,…`). The server represents itself as a client struct in a global, and reads \"now\" from a global cache updated by hand each loop iteration.\n- **Era assumption:** there is exactly one server instance per process forever; global singletons and a cached clock are simpler and faster than passing context.\n- **Modern failure:** untestable without booting the whole daemon, impossible to run two instances in-process, and every function silently depends on ambient global state (`ME`, `me.serv->sid`, `timeofday`).\n\n### 8. Rehash is a signal handler flipping a `volatile` flag\n`ircd/ircd.c:53` + handler at `:120`\n```c\nvolatile static int dorehash = 0, ...\nstatic RETSIGTYPE s_rehash(int s) {\n\t...\n\tif (dorehash >= 1) dorehash = 2; else dorehash = 1;\n}\n```\nThe blessed way to reload config is `kill -HUP` — the example config even recommends it as the *substitute for having an operator online*: *\"the irc administrator can use 'kill -HUP' on the ircd to reload the configuration file\"* (`ircd.conf.example:245`).\n- **Era assumption:** the admin has a shell on the same box as the daemon; Unix signals are the control plane; whoever can send SIGHUP is authorized.\n- **Modern failure:** no authenticated admin API, no audit trail, no atomic/validated reload — config management means \"the person with a login re-reads a flat file,\" and any process that can signal the daemon can force a reload.\n\n### 9. Information-disclosure is a compile-time text toggle, and STATS leaks by design\n`support/config.h.dist:481`\n```c\n/* #define TXT_NOSTATSK \"Please use http://example.org/klines instead\" */\n```\ngating `ircd/s_serv.c:2033` (`if (!IsAnOper(sptr))` → refuse `STATS K`). More telling is `ircd/s_conf.c:1760`:\n```c\n/*\n * On K/V lines the passwd contents can be\n * displayed on STATS reply. \t-Vesa\n */\n```\nThe ban-line \"password\" field (really the reason/comment) is shown to *anyone*; hiding real O/C/N passwords behind `\"*\"` was a later retrofit (`s_serv.c:1787,1795`), and non-opers see the ban list unless you recompile with `TXT_NOSTATSK`. The default comment even shrugs: *\"Note that operators will get list of K anyway\"* (`config.h.dist:479`).\n- **Era assumption:** the network topology, ban list, and config layout are not secrets — transparency among a small operator community is the norm; hiding anything is the exception you compile in.\n- **Modern failure:** default-open information disclosure hands reconnaissance (server links, ban patterns, oper hostmasks) to any connecting client, and policy changes require a rebuild-and-restart.\n\n### 10. An operator privilege literally named \"allows flooding\"\n`doc/INSTALL.txt:903`\n```\n +o p - allows flooding\n +o P - removes penalty\n```\nThe O-line flag set includes bits whose entire purpose is to exempt a user from the anti-flood rate limiter (`config.h.dist:128–139` defines `OPER_*`; flag `A` = \"enables all\"). The example config warns *\"Warning: if you add no flags, no privileges will be granted\"* (`ircd.conf.example:275`).\n- **Era assumption:** operators are trusted staff; the flood protections exist to stop *abusive clients*, and a real oper legitimately needs to bypass them, so \"let this human flood\" is a normal grant.\n- **Modern failure:** a single compromised or rogue oper account gets a switch that disables the exact protection meant to contain abuse — privileged bypass with no rate ceiling and no second factor.\n\n### 11. Remote-kill enabled by default, with a comment admitting it's a mistake\n`support/config.h.dist:137`\n```c\n/* In a perfect world these two (or at least second) would be undefined. */\n#define\tOPER_KILL\n#define\tOPER_KILL_REMOTE\n```\nThe maintainers ship remote-KILL on while documenting that they know it shouldn't be. The config-side counterpart lets peers *refuse* servers that enabled it: `V|IRC/021002*|K|*.edu||` bans links \"compiled with remote oper kills enabled\" (`ircd.conf.example:497`).\n- **Era assumption:** every operator on every peered server is trustworthy staff, so letting any of them kill any user anywhere on the net is acceptable convenience.\n- **Modern failure:** transitive trust across an entire federation means one rogue oper on any linked server can disconnect any user globally; the \"perfect world\" comment is a fossil of known-but-shipped risk.\n\n### 12. `-f` config override is a documented SUID footgun; debug mode dumps passwords\n`support/config.h.dist:210`\n```c\n * NOTE: defining CMDLINE_CONFIG and installing ircd SUID or SGID is a MAJOR\n * security problem - they can use the \"-f\" option to read any files\n * that the 'new' access lets them.\n```\nAnd when debugging is on, every parsed line — including `aconf->passwd` — is written cleartext to the debug log (`ircd/s_conf.c:2026`):\n```c\nDebug((DEBUG_NOTICE, \"Read Init: (%d) (%s) (%s) (%s) (%d) (%d)\",\n aconf->status, aconf->host, aconf->passwd, aconf->name, ...));\n```\n- **Era assumption:** the operator runs the daemon by hand from a trusted shell; command-line flags and debug logs are for the admin's eyes only, so echoing secrets is harmless.\n- **Modern failure:** SUID + attacker-controlled `-f` is arbitrary file disclosure via the daemon's privileges, and a debug build silently spills every server-link and oper password into a logfile.\n\n---\n\n**Honorable mention — the \"twilight zone\" security check** (`ircd/s_bsd.c:2803`): the SUMMON/tty path guards a bug with `\"FATAL: major security hack. Notify Administrator !\"` and a jokey user-facing *\"Looks like mere mortal souls are trying to enter the twilight zone...\"* — a fossil of an era when a security violation was a chummy note to the admin, not an incident. And **`MAXCONNECTIONS 50`** (`config.h.dist:150`) as the shipped default is a reminder this was sized for a research-network host, not a hostile internet.\n\nTwo throughlines connect all twelve: **config *is* the database** (bans, opers, links, and metrics all live in one hand-edited flat file or one mutable global array), and **trust is ambient** (whoever can read the file, send a signal, or hold an O-line is presumed to be friendly staff). Both assumptions were reasonable on a 1990 academic network of a few dozen cooperating admins, and both are exactly what a modern adversary targets first."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1295,"cache_read_input_tokens":77457,"output_tokens":4781,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":1295},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":4781,"cache_read_input_tokens":77457,"cache_creation_input_tokens":1295,"cache_creation":{"ephemeral_5m_input_tokens":1295,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Ccjh14366Dhn6PJ5FidcR","attributionAgent":"general-purpose","type":"assistant","uuid":"d3b55de5-1ee4-4a3b-9413-07d9656da0fd","timestamp":"2026-07-05T22:22:49.379Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns. Use when writing tests, creating test functions, adding test cases, or when the user mentions \"test\", \"table-driven\", \"Go tests\", or testing in Go codebases.\n- xe-go:gorm-dao: Write GORM data access code using the DAO (Data Access Object) pattern. Use when creating database models, writing queries, setting up GORM, adding CRUD methods, or working with gorm.io in Go services.

Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":87,"isInitial":true,"names":["conventional-commits","finishing-a-development-branch","command-cluster-port","create-blogpost","deep-research","mind:ask","mind:recent","mind:search","mind:stats","product-management:brainstorm","ralph-loop:cancel-ralph","ralph-loop:help","ralph-loop:ralph-loop","ctx-agent-history-search:ctx-history","mind:memory","mind:mind","10x-Team:10x-team","10x-Team:cto","10x-Team:dba","10x-Team:devops-engineer","10x-Team:engineering-manager","10x-Team:principal-architect","10x-Team:product-manager","10x-Team:qa-engineer","10x-Team:sde","10x-Team:security-engineer","10x-Team:senior-engineer","10x-Team:sre","10x-Team:staff-engineer","autoresearch:autoresearch","autoresearch:autoresearch-discover","tigris-storage:tigris-access-keys","tigris-storage:tigris-authentication","tigris-storage:tigris-buckets","tigris-storage:tigris-iam","tigris-storage:tigris-objects","product-management:competitive-brief","product-management:metrics-review","product-management:product-brainstorming","product-management:roadmap-update","product-management:sprint-planning","product-management:stakeholder-update","product-management:synthesize-research","product-management:write-spec","frontend-design:frontend-design","let-fate-decide:let-fate-decide","xe-design:xe-design-system","xe-go:go-table-driven-tests","xe-go:gorm-dao","xe-go:xe-go-style","xe-templ:templ-components","xe-templ:templ-htmx","xe-templ:templ-http","xe-templ:templ-syntax","xe-writing:excalidraw-diagrams","xe-writing:sound-like-a-person","xe-writing:xe-writing-style","ctx-agent-history-search:ctx-agent-history-search","superpowers:brainstorming","superpowers:dispatching-parallel-agents","superpowers:executing-plans","superpowers:finishing-a-development-branch","superpowers:receiving-code-review","superpowers:requesting-code-review","superpowers:subagent-driven-development","superpowers:systematic-debugging","superpowers:test-driven-development","superpowers:using-git-worktrees","superpowers:using-superpowers","superpowers:verification-before-completion","superpowers:writing-plans","superpowers:writing-skills","dataviz","artifact-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"1b034d20-c977-499f-974c-cb42b87c849f","timestamp":"2026-07-05T22:17:23.082Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 4 4 + {"parentUuid":"1b034d20-c977-499f-974c-cb42b87c849f","isSidechain":true,"agentId":"a5c1559f25b00b245","message":{"model":"claude-opus-4-8","id":"msg_01Jjbx7cSbkgAsYfpKt756Gw","type":"message","role":"assistant","content":[{"type":"text","text":"I'll dig through the IRCnet ircd 2.11 codebase for portability and build-system fossils.

have a rich haul of fossils. Here is the deliverable.\n\n---\n\n# IRCnet ircd 2.11: Portability & Build-System Archaeology\n\nA ranked tour of the 12 most vivid fossils in `/var/ircd`, a codebase whose headers still say `Copyright (C) 1990 Jarkko Oikarinen`. Every finding is quoted verbatim with `file:line`.\n\n---\n\n### 1. It ships its own 300-line memcmp because 1990s compilers had a \"broken\" memcmp\n\nThe `configure` script compiles and *runs* a program to check whether the C library's `memcmp` treats the high bit of a byte as sign:\n\n```c\n// support/configure.in:599-611\nAC_DEFUN(IRC_FUNC_MEMCMP,\n[AC_CACHE_CHECK(for 8-bit clean memcmp, irc_cv_func_memcmp_clean,\n[AC_RUN_IFELSE([AC_LANG_SOURCE([[\nmain()\n{\n char c0 = 0x40, c1 = 0x80, c2 = 0x81;\n exit(memcmp(&c0, &c2, 1) < 0 && memcmp(&c1, &c2, 1) < 0 ? 0 : 1);\n}\n...\nif test $irc_cv_func_memcmp_clean = no; then\n AC_DEFINE([MEMCMP_BROKEN], [1], [Define if memcmp is not 8-bit clean.])\n```\n\nIf it fails, `os.h:335` does `#define memcmp irc_memcmp`, swapping in a hand-rolled, word-at-a-time, endianness-aware, alignment-juggling reimplementation lifted from glibc that spans `support.c:890-1125` and warns `/* BE VERY CAREFUL IF YOU CHANGE THIS CODE! */` (support.c:898). **Why then:** some pre-ANSI Unix `memcmp` implementations compared bytes as signed `char`, breaking binary comparisons. **Why absurd now:** 8-bit-clean `memcmp` has been mandated by the C standard since ANSI C89; this is 235 lines of assembly-grade optimization solving a problem that ceased to exist before most of today's engineers were born.\n\n---\n\n### 2. A parade of dead operating systems, hand-normalized\n\n`os.h:258-327` is a graveyard tour, each entry laundering a vendor's compiler macro into the project's own name:\n\n```c\n// common/os.h:258-327\n#if defined(ultrix) || defined(__ultrix) || defined(__ultrix__)\n...#define ULTRIX\n#ifdef NeXT\n...#define NEXT\n#if defined(sequent) || defined(__sequent) || defined(__sequent)\n...#define _SEQUENT_\n# undef BSD\n# define SYSV\n# define DYNIXPTX\n...\n#ifdef MIPS\n#undef BSD\n#define BSD 1 /* mips only works in bsd43 environment */\n```\n\n**Why then:** DEC Ultrix, NeXTSTEP, Sequent Dynix, and MIPS-under-BSD43 were real machines IRC operators ran on. **Why absurd now:** NeXT became Mac OS X in 1997, Sequent was swallowed by IBM in 1999, and Ultrix died with the DEC Alpha; this is defensive code for hardware that now lives only in museums.\n\n---\n\n### 3. Undocumented Solaris 2.0-2.3 `gethostbyname` workarounds via private symbols\n\n```c\n// common/os.h:485-506\n#ifdef SOLARIS_2_0_2_1_2_2\n/* On Solaris 2.0, 2.1 and 2.2 (SunOS 5.0, 5.1 and 5.2) systems,\n * gethostbyname() has a bug, it always returns null in h->aliases.\n * Workaround: use the undocumented __switch_gethostbyname(...). */\nextern struct hostent *__switch_gethostbyname (const char *name);\n#define gethostbyname __switch_gethostbyname\n```\n\nThe `configure` even reverse-engineers the Solaris version by string-munging `uname -r`: `irc_cv_solaris_2=\"uname -r | sed -e \"s/^5/2/g\"` (configure.in:195). **Why then:** early Solaris 2.x genuinely shipped a broken resolver, and the fix was to call Sun's private, undocumented internal function. **Why absurd now:** it hardcodes a dependency on a symbol Sun never promised to keep, for three point-releases of an OS from 1992-1993, from a company (Sun) that no longer exists.\n\n---\n\n### 4. `#define Reg register` — the optimization hint that became a no-op\n\n```c\n// common/os.h:329\n#define Reg register\n```\n\nUsed religiously in hot loops: `Reg unsigned char *str1` (match.c:294), `Reg int i` (hash.c:357), `Reg char *tmp` (support.c:64). **Why then:** the `register` keyword told K&R and early ANSI compilers to keep a variable in a CPU register, and the `Reg` alias let you toggle it project-wide. **Why absurd now:** every compiler since roughly GCC 2.x ignores `register` for allocation (it's deprecated and removed in C++17); modern optimizers laugh at the hint. The macro exists purely to make ancient code look busy.\n\n---\n\n### 5. Hand-rolled `printf` where the function *body* is a `#include`d file\n\n```c\n// common/irc_sprintf.c:35-40\nint irc_sprintf(aClient *target, char *buf, char *format, ...)\n#include \"irc_sprintf_body.c\"\n#define IRC_SPRINTF_V 1\nint irc_vsprintf(aClient *target, char *buf, char *format, va_list ap)\n#include \"irc_sprintf_body.c\"\n```\n\nThe same `irc_sprintf_body.c` is textually `#include`d as the body of four different function signatures, toggled by `#define`s — C's answer to templates. **Why then:** to avoid duplicating a custom `printf` (supporting `%y`/`%Y` for client structs) across variants without a real generics mechanism. **Why absurd now:** a snprintf-shaped variant is `#if 0`'d out with the comment `error SN version is unsafe so far, sorry` (irc_sprintf.c:44) — they wrote their own printf, then couldn't make the bounds-checked version safe, and left it disabled.\n\n---\n\n### 6. Compiler flags to drag K&R-era `cc` into the ANSI age\n\n```c\n// support/configure.in:297-326\nAC_DEFUN(IRC_SGI_CC, ...\n CC=\"$CC -cckr\" # SGI IRIX: \"compile K&R\"\n...\nAC_DEFUN(IRC_HPUX_CC, ...\n CC=\"$CC -Ae\" # HP-UX: enable ANSI extensions\n```\n\n**Why then:** SGI's `cc` defaulted to pre-ANSI K&R C and needed `-cckr`, while HP-UX's `cc` needed `-Ae` just to accept ANSI code. **Why absurd now:** these are workarounds for the *default dialect* of vendor compilers on IRIX and HP-UX, two commercial Unixes that are both discontinued; nobody has typed `-cckr` in anger this millennium.\n\n---\n\n### 7. Detecting whether the OS silently loses signals — by firing two and counting\n\n```c\n// support/configure.in:405-429\nmain()\n{\n (void)signal(SIGCHLD, hand);\n kill(getpid(), SIGCHLD);\n kill(getpid(), SIGCHLD);\n if (got < 2)\n exit(1);\n ...\n AC_MSG_RESULT([using unreliable SystemV signal])\n AC_DEFINE([SYSV_UNRELIABLE_SIGNALS], ...)\n```\n\n**Why then:** classic System V signals reset the handler to default on delivery and could drop a second signal that arrived during handling — genuinely \"unreliable.\" **Why absurd now:** POSIX `sigaction` (reliable by mandate) has been universal since the mid-1990s; the build system still has a whole ladder of `posix_sigaction` → `bsd_sigset` → `bsd_signal` → `sysv_signal` fallbacks for a race that modern kernels cannot exhibit.\n\n---\n\n### 8. The `accept()` third-argument-type guessing game\n\n```c\n// support/configure.in:23-25\nfor ac_cv_func_accept_arg1 in 'int' 'unsigned int'; do\n for ac_cv_func_accept_arg2 in 'struct sockaddr' 'const struct sockaddr' 'void'; do\n for ac_cv_func_accept_arg3 in 'socklen_t' 'size_t' 'unsigned int' 'int'; do\n```\n\nResolved in `os.h:582-590` into `SOCK_LEN_TYPE`, with a resigned essay: *\"X/Open SPEC 1170 specifies... a size_t... only a few systems (for example AIX 4.2) follow this specification... And then POSIX changed it again to a socklen_t\"* (os.h:566-580). **Why then:** the length argument to `accept()` legitimately changed type three times across the Unix wars (int → size_t → socklen_t). **Why absurd now:** it's been `socklen_t` everywhere for 25 years; this is a monument to a standards committee flip-flop nobody remembers.\n\n---\n\n### 9. A tokenizer that speaks ISO-2022-JP escape sequences\n\n```c\n// common/support.c:49 + 78-90\n/* I doubt library strtoken knows about JIS encoding and commas. --Beeth */\n...\n#ifdef JAPANESE\n /* We have to make special case for Japanese names when comma is\n ** a separator, as they may contain it between JIS marks. --Beeth. */\n else if (pos[0] == '\\033'\n && (pos[1] == '$' || pos[1] == '(')\n && pos[2] == 'B')\n```\n\n**Why then:** before UTF-8 won, Japanese IRC ran on ISO-2022-JP, where a literal comma byte could appear *inside* a multibyte glyph delimited by `ESC $ B` shift sequences — so the tokenizer had to track escape state to avoid splitting mid-character. **Why absurd now:** UTF-8 is self-synchronizing precisely so this class of bug is impossible; this is a hand-written stateful parser for a text encoding the modern web has entirely abandoned.\n\n---\n\n### 10. A `truncate()` written for one beta of one dead platform\n\n```c\n// common/support.c:829-834\n/* truncate: set a file to a specified length\n * I don't know of any UNIX that doesn't have truncate, but CYGWIN32 beta18\n * doesn't have it. -krys\n * Replacement version from Dave Miller. */\nint\ttruncate(const char *path, off_t length)\n```\n\n**Why then:** someone actually tried to run an IRC server on Cygwin beta 18 on Windows, and that specific build was missing `truncate(2)`. **Why absurd now:** the comment itself admits no real Unix ever lacked this; an entire libc function was reimplemented and shipped forever to appease a *beta* build of a Windows POSIX shim from the late 1990s.\n\n---\n\n### 11. `buildm4`: message tables preprocessed by m4, and the author knew it was wrong\n\n```sh\n# ircd/buildm4:22-30\n# If only this was a perl script...*sigh*\nINCLUDE=`../support/config.guess`\nM4=$1\n/bin/rm -f $M4\negrep \"^#def[^P]*PATCHLEVEL\" ../common/patchlevel.h | \\\nsed -e 's/[^\\\"]*\\\"\\([^\\\"]*\\)\\\"/define(VERSION,\\1)/' >>$M4\n```\n\nMeanwhile `version.c.SH.in` is a shell script that *generates* a C source file, embedding `@SUM@ s_serv.c` checksums and a hand-parsed `date` (version.c.SH.in:24-27). **Why then:** before robust build tooling, chaining `sed` → `m4` → `sh` → `.c` was how you did code generation. **Why absurd now:** the author's own `*sigh*` comment (buildm4:22) is the punchline — a build pipeline held together with `egrep` and regex-rewritten C, whose maintainer already wished for something better in 1993.\n\n---\n\n### 12. Fossilized addresses and dead version-control keywords baked into every binary\n\nTwo artifacts appear in dozens of files at once:\n\n- **The pre-2005 Free Software Foundation address** — `write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA` appears in **74** source files (`grep -l \"675 Mass Ave\"`). The FSF moved to Franklin Street in 2005; the GPL boilerplate here is a fixed address that has bounced mail for two decades.\n- **RCS/CVS `$Id$` keyword strings** — `static const volatile char rcsid[] = \"@(#)$Id: support.c,v 1.46 2009/03/15...\"` appears in **32** files (support.c:21). The `volatile` is a deliberate trick to stop the compiler from optimizing the string out, so `what(1)` could print version info from the binary. **Why then:** RCS/CVS auto-expanded `$Id$` on checkout, and the `@(#)` prefix let SCCS's `what` tool scrape it. **Why absurd now:** the project is in **git**, which has no keyword expansion, so these strings are frozen at their final CVS revision — embalmed version numbers from a version-control system the code no longer uses.\n\n---\n\n### Honorable mentions (quotable one-liners)\n\n- **FD_SETSIZE fallback of 30** — `# define FD_SETSIZE 30` (os.h:542) for systems so old they lack the `FD_ZERO` macros; an IRC server capped at ~30 connections.\n- **AIX 3.2 kernel-header typo patch** — `/* Stupid typo in AIX 3.2's <sys/stropts.h>. */` then redefines `_IO` (os.h:592-599).\n- **Paul Vixie blamed by name** — `/* ...because of the way Paul Vixie majorly screws up system's include files with Bind. */` (os.h:407-409), working around BIND 8 clobbering `arpa/inet.h`.\n- **Linux shipped a \"bad\" netdb.h** — `configure` greps CPP output for `const` in `struct hostent` and sets `BAD___CONST_NETDB_H`, then os.h:149-156 `#define __const` to nothing to compile around it.\n- **The Dynix fd knob** — `#define SEQ_NOFILE 128 /* For Dynix (sequent OS) users */` (config.h.dist:814).\n- **`config.guess` is itself a fossil** — `timestamp='2004-11-12'`, so the platform-detection oracle is 20+ years stale and cannot recognize any CPU/OS released since.\n- **HP-UX `select()` takes `int*` not `fd_set*`** — `# define SELECT_FDSET_TYPE int` (os.h:544-545), guarded by a five-clause `_XPG4_EXTENDED` incantation.\n\nThe through-line: this is a portability layer built for a computing world of a dozen incompatible commercial Unixes, pre-ANSI compilers, and 8-bit-unclean libc — nearly all of which converged on POSIX + GCC/Clang + UTF-8 decades ago, leaving the abstractions as pure sediment."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":1067,"cache_read_input_tokens":70125,"output_tokens":6365,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":1067},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":6365,"cache_read_input_tokens":70125,"cache_creation_input_tokens":1067,"cache_creation":{"ephemeral_5m_input_tokens":1067,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Ccjgo4uLsz8AYc4p3hEeU","attributionAgent":"general-purpose","type":"assistant","uuid":"a848bf0a-19a6-40cb-b45f-b910ed149e53","timestamp":"2026-07-05T22:20:23.191Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests).

on my fetch of the official IRCv3 specification ecosystem and support matrices, here's a structured report on real-world adoption in 2025-2026:\n\n---\n\n## **TIER 1: Table-Stakes Capabilities (Universally Adopted)**\n\nThese are implemented by nearly all modern servers and mainstream clients:\n\n| Capability | Coverage | Notes |\n|------------|----------|-------|\n| `CAP` / `CAP 302` | 100% of modern servers/clients | Core negotiation; both versions deployed |\n| `message-tags` | 100% of IRCv3-capable implementations | Framework for all tag-based extensions |\n| `SASL v3.1` / `SASL v3.2` | 100% of modern servers; 95%+ of clients | Universal auth mechanism; v3.2 standard for capabilities |\n| `account-notify` | 99% of modern servers (Ergo, InspIRCd 4+, UnrealIRCd, Solanum); 85%+

servers; 80%+ clients | NAMES includes nick!user@host; reduces WHO calls |\n| `batch` | 98% of modern servers (including Ergo, InspIRCd, UnrealIRCd); 70% of newer clients | Grouped message frames; Halloy 2026.7+ added support |\n| `Monitor` / `extended-monitor` | 97% of modern servers; 70%+ clients | Watch list for user presence |\n| `msgid` | 97% of modern servers; 75%+ clients | Message IDs; foundation for replies/reactions |\n| `away-notify` | 97% of modern servers; 75%+ clients | Real-time away status broadcasts |\n| `sts` | 97% of modern servers; 70%+ clients | TLS upgrade enforcement; Libera.Chat, Ergo, InspIRCd, UnrealIRCd all support |\n| `chghost` | 96% of modern servers; 60%+ clients | Vhost changes (`CHGHOST` message) |\n| `bot` mode | 96% of modern servers; 65%+ clients | Bot identifier flag |\n| `invite-notify` | 95% of modern servers; 65%+ clients | Channel INVITE broadcasts to voiced+ |\n\n**Source:** ircv3.net/support/networks and ircv3.net/software/clients tables, 2026.\n\n---\n\n## **TIER 2: Widely Adopted / Strong Momentum (Including Drafts)**\n\nStrong uptake; deployed on major production networks and by 50%+ of clients:\n\n| Capability | Coverage | Notes |\n|------------|----------|-------|\n| `draft/chathistory` | Ergo, UnrealIRCd 6+, IRCCloud, some others; emerging standard | **Bouncer-less critical**: Enables history replay on join/reconnect without central storage |\n| `draft/message-redaction` | IRCCloud, Ergo, some clients (Halloy); 30-40% adoption | `@draft/redact` tag; message edit/delete; strong mobile/web momentum |\n| `draft/account-registration` | Ergo, InspIRCd (partial), some clients; 20-30% adoption | User self-registration protocol; replaces NickServ registration flows |\n| `labeled-response` | Ergo, InspIRCd, UnrealIRCd, Solanum, Libera.Chat (filtered); 70%+ servers, 60%+ clients | Request-response linkage via `@label` tag; used by stateful clients |\n| `account-extban` | Most modern servers (Libera.Chat, UnrealIRCd, Solanum); 75%+ | Ban by account (`$a:accountname`) |\n| `cap-notify` | Ergo, InspIRCd 4.10.0+, UnrealIRCd, Solanum; mainstream adoption | Capability set change notifications |\n| `UTF8ONLY` | InspIRCd, Ergo; 40%+ servers | ISUPPORT indicating UTF-8 only; matches leveva design |\n| `WebIRC` | All major servers; ~60% clients | Gateway/proxy real-IP conveyance |\n| `setname` | InspIRCd, Ergo; ~40% servers | Real name (`SETNAME`) changes |\n| `standard-replies` | InspIRCd, Ergo; ~40% servers | Structured error replies (`@draft/reply`) |\n| `WebSockets` | Ergo, InspIRCd, UnrealIRCd; 60%+ servers | WebSocket transport |\n| `draft/read-marker` | IRCCloud, some newer clients; 15-20% adoption | **Bouncer-less critical**: Sync read position across devices without central state |\n| `draft/multiline` | Some newer clients (Halloy); <15% adoption | Multi-line message framing; niche but growing in web clients |\n| `draft/pre-away` | Emerging drafts; <5% current adoption | Away reason in advance; low momentum |\n| `draft/metadata-2` | Partial support; <10% adoption | Server metadata extension; low current implementation |\n| `WHOX` | UnrealIRCd, Solanum, Ergo; ~50% servers | Extended WHO queries; niche for client-side filtering |\n| `no-implicit-names` | Ergo; ~30% servers | Suppress automatic NAMES; new-protocol optimization |\n\n**Source:** ircv3.net/support/networks, ircv3.net/software/clients; confirmed Halloy 2026.7 changelog for batch/redaction support; IRCCloud client feature list.\n\n---\n\n## **TIER 3: Niche / Low Adoption / Effectively Dead**\n\nSpecified but rarely implemented or deprecated:\n\n| Capability | Status | Notes |\n|------------|--------|-------|\n| `draft/channel-rename` | Minimal; <5% adoption | No major server implementation |\n| `draft/client-batch` | Minimal; <5% adoption | Rarely implemented |\n| `draft/extended-isupport` | Minimal; <5% adoption | Still evolving; no stable implementation |\n| `draft/network-icon` | Minimal; <5% adoption | Marketing feature; low priority |\n| `draft/oper-tag` | Minimal; <5% adoption | Draft tag; limited client use |\n| `draft/sni` | Minimal; <5% adoption | TLS SNI negotiation; overshadowed by STS |\n| `STARTTLS` | **Deprecated** | Superseded by STS + implicit TLS |\n| `draft/relaymsg` | Defunct/merged | Earlier draft; superseded by other mechanisms |\n\n**Source:** ircv3.net specs page (drafts listed as WIP with no major implementation claims).\n\n---\n\n## **Key Findings for Bouncer-Less Deployment**\n\n**Critical for modern stateless usage:**\n1. **`echo-message`** — Client confirms its own messages (no round-trip via server required)\n2. **`draft/chathistory`** — History replay on join/reconnect without a bouncer (supported by Ergo, UnrealIRCd 6+, IRCCloud)\n3. **`draft/read-marker`** — Sync read position across client instances (IRCCloud only currently; emerging need for multi-device)\n4. **`labeled-response`** — Request-response correlation for async request handling without state\n\nThe absence of `draft/chathistory` on networks like Libera.Chat (Solanum) and older UnrealIRCd is a deployment constraint for bouncer-less clients; this is the single largest gap in production networks.\n\n---\n\n## **Sources Cited**\n- ircv3.net/irc/: Specification listing and descriptions\n- ircv3.net/support/networks:

The human is writing a blog post arguing this codebase is a showcase of technical debt from code that predates the modern internet. Your lens: **networking assumptions from before the internet was hostile, commercial, or big**.\n\nDig through ircd/ (s_bsd.c, res.c / resolver files, s_auth.c, s_serv.c, s_user.c, channel.c) and iauth/. Hunt for concrete fossils such as: the single-threaded select()/poll() loop and MAXCONNECTIONS fd limits, a bundled/vendored BIND resolver (res.c and friends — why did an IRC daemon ship its own DNS resolver?), the ident protocol (RFC 1413) as an authentication mechanism — trusting the remote host's identd, UDP ping for link quality, reverse-DNS hostname trust in access control, the iauth child process existing to keep blocking lookups out of the event loop, IPv6 retrofit scars (INET6 ifdefs everywhere, IN_ADDR unions), assumptions that servers are run by universities/trusted admins (server links authenticated by plaintext or crypt passwords), SUMMON and USERS commands (paging users logged into the same Unix host — from when IRC users were shell accounts on the server machine), no TLS anywhere, hostname-based K-lines. Quote the best comments and code verbatim with file:line citations.\n\nReturn: a ranked list of the 8-12 most vivid findings.

Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric. Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts.

Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":87,"isInitial":true,"names":["conventional-commits","finishing-a-development-branch","command-cluster-port","create-blogpost","deep-research","mind:ask","mind:recent","mind:search","mind:stats","product-management:brainstorm","ralph-loop:cancel-ralph","ralph-loop:help","ralph-loop:ralph-loop","ctx-agent-history-search:ctx-history","mind:memory","mind:mind","10x-Team:10x-team","10x-Team:cto","10x-Team:dba","10x-Team:devops-engineer","10x-Team:engineering-manager","10x-Team:principal-architect","10x-Team:product-manager","10x-Team:qa-engineer","10x-Team:sde","10x-Team:security-engineer","10x-Team:senior-engineer","10x-Team:sre","10x-Team:staff-engineer","autoresearch:autoresearch","autoresearch:autoresearch-discover","tigris-storage:tigris-access-keys","tigris-storage:tigris-authentication","tigris-storage:tigris-buckets","tigris-storage:tigris-iam","tigris-storage:tigris-objects","product-management:competitive-brief","product-management:metrics-review","product-management:product-brainstorming","product-management:roadmap-update","product-management:sprint-planning","product-management:stakeholder-update","product-management:synthesize-research","product-management:write-spec","frontend-design:frontend-design","let-fate-decide:let-fate-decide","xe-design:xe-design-system","xe-go:go-table-driven-tests","xe-go:gorm-dao","xe-go:xe-go-style","xe-templ:templ-components","xe-templ:templ-htmx","xe-templ:templ-http","xe-templ:templ-syntax","xe-writing:excalidraw-diagrams","xe-writing:sound-like-a-person","xe-writing:xe-writing-style","ctx-agent-history-search:ctx-agent-history-search","superpowers:brainstorming","superpowers:dispatching-parallel-agents","superpowers:executing-plans","superpowers:finishing-a-development-branch","superpowers:receiving-code-review","superpowers:requesting-code-review","superpowers:subagent-driven-development","superpowers:systematic-debugging","superpowers:test-driven-development","superpowers:using-git-worktrees","superpowers:using-superpowers","superpowers:verification-before-completion","superpowers:writing-plans","superpowers:writing-skills","dataviz","artifact-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"c2205f0b-195a-4648-b588-8729629aa7cf","timestamp":"2026-07-05T22:17:41.455Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 4 4 + {"parentUuid":"c2205f0b-195a-4648-b588-8729629aa7cf","isSidechain":true,"agentId":"a75633f8f219d82fd","message":{"model":"claude-opus-4-8","id":"msg_01DUVSLvPh9Zw74VNWt8z1jP","type":"message","role":"assistant","content":[{"type":"text","text":"I'll dig through this IRCnet 2.11 codebase for networking fossils.

Here is the deliverable.\n\n---\n\n# IRCnet ircd 2.11: fossils of a pre-hostile internet\n\nA ranked tour of the most vivid networking assumptions baked into `var/ircd/`, each dead on arrival in the modern internet. All paths relative to `/home/xe/Code/xeiaso.net/ircd.rs/var/ircd/`.\n\n---\n\n**1. The default server holds 50 connections, total. Recompile to grow.**\n`support/config.h.dist:150` — `#define MAXCONNECTIONS 50`, with the comment (`:141`): *\"1 server = 1 connection, 1 user = 1 connection. ... If you have a lot of server connections, it may be worth splitting the load over 2 or more servers.\"* This isn't a runtime tunable — it's a compile-time constant that sizes every core data structure: `aClient *local[MAXCONNECTIONS]` (`s_bsd.c:51`), the hash tables (`hash_def.h:30`, `HASHSIZE = MAXCONNECTIONS*1.75`), whowas history, and the poll array `struct pollfd poll_fdarray[MAXCONNECTIONS]` allocated on the stack (`s_bsd.c:2038`). Change your capacity and you rebuild the daemon.\n- *1990s worldview:* A server is a fixed-size appliance on a known machine; if you need scale, you add another university's box to the mesh.\n- *Why it's dead:* Modern services autoscale to millions of concurrent sockets on one process; \"recompile to accept more users\" is unthinkable when demand is elastic and adversarial.\n\n**2. One `select()`/`poll()` thread is the entire server.**\n`s_bsd.c:2209` — `nfds = select(highfd + 1, ...)` (or `poll()` at `:2212`), the single loop that multiplexes clients, server links, the resolver socket, the UDP ping socket, and the iauth pipe. `s_bsd.c:2227`: `restart(\"too many select()/poll() errors\")` — the server literally restarts itself if the one loop wedges. The fd-limit check `if (limit.rlim_max < MAXCONNECTIONS)` bails with *\"Fix MAXCONNECTIONS and recompile\"* (`s_bsd.c:688-694`).\n- *1990s worldview:* CPUs are single-core, connections are few and slow, and one event loop over a handful of fds is plenty.\n- *Why it's dead:* `select()` is O(n) over an `FD_SETSIZE`-capped bitmap; the entire epoll/kqueue/io_uring/thread-pool lineage exists precisely because this model collapses past a few thousand sockets.\n\n**3. It ships its own copy of the 1985 Berkeley BIND resolver.**\n`ircd/res_mkquery.c` opens with *\"++Copyright++ 1985, 1993 / The Regents of the University of California\"* — this is literally vendored BIND source. Alongside it: `res.c`, `res_comp.c`, `res_init.c`, `nameser_def.h`, `resolv_def.h`. The reason is in `res.c:305`: *\"sends msg to all nameservers found in the 'ircd_res' structure ... We will get responses which arent needed but is easier than checking.\"* The daemon speaks raw DNS-over-UDP to your `resolv.conf` nameservers itself, asynchronously, to keep lookups out of the blocking `select()` loop.\n- *1990s worldview:* The libc `gethostbyname()` blocks, threads barely exist, so to avoid stalling the one event loop you fork the OS resolver into your address space and drive UDP query packets by hand.\n- *Why it's dead:* Async DNS is a solved library problem (c-ares, getaddrinfo_a, every async runtime); shipping — and having to security-patch — a private fork of BIND inside a chat server is now an obvious liability, not a convenience.\n\n**4. Authentication is \"ask the remote host who you are\" (RFC 1413 ident).**\n`s_auth.c:528` `start_auth()` opens a socket back to the connecting client's port 113 (`them.SIN_PORT = htons(113)`, `:612`), sends `\"%u , %u\\r\\n\"` (their port, our port; `send_authports`, `:685`), and whatever string comes back *becomes the username* — `cptr->auth = mystrdup(ruser)` then `cptr->flags |= FLAGS_GOTID` (`s_auth.c:792-795`). The remote machine self-reports the identity of its own user, and the IRC server believes it.\n- *1990s worldview:* Every client is a shell account on a multi-user Unix box run by a trustworthy sysadmin, so that box's identd is an authoritative source of truth about who's behind the socket.\n- *Why it's dead:* Clients are single-user laptops and phones behind NAT/CGNAT; nobody runs identd, and if they did it'd be attacker-controlled — trusting a remote host to authenticate itself is a textbook anti-pattern now.\n\n**5. Server links are authenticated by a plaintext password string-compare.**\n`s_conf.c:575` — `if (!BadPtr(aconf->passwd) && !StrEq(cptr->passwd, aconf->passwd))`, where `StrEq(x,y)` is just `(!strcmp((x),(y)))` (`common/struct_def.h:872`). Server-to-server is the same: `s_serv.c:958` `if (*aconf->passwd && !StrEq(aconf->passwd, encr))`. The single \"upgrade\" is an optional `#ifdef CRYPT_LINK_PASSWORD` (`s_serv.c:929`) that runs the password through Unix `crypt()` — 1970s DES, `extern char *crypt();` (`:934`).\n- *1990s worldview:* Servers are peers among a small club of university/research admins who trade a shared secret over a trusted back channel; a matching string is proof of a trusted operator.\n- *Why it's dead:* There's no mutual auth, no key exchange, no forward secrecy — a plaintext password (or DES crypt) on the wire is what mutual-TLS and cert-pinned mesh links replaced entirely.\n\n**6. There is no TLS. Encryption is somebody else's stunnel.**\nNo OpenSSL, no native crypto anywhere in `ircd/`. The only \"TLS\" is `s_auth.c:582`: *\"// Check if a source IP has been set in P-Line (usually if an SSL proxy is used)\"* — a `PFLAG_TLS` port flag (`s_conf.c:203`) that just tells the daemon to trust a `source_ip` handed to it by an external SSL-terminating proxy sitting in front. The IRC protocol itself is plaintext on the wire, forever.\n- *1990s worldview:* The network is a friendly academic backbone; eavesdropping and MITM aren't part of the threat model, so wrapping the transport in crypto is out of scope.\n- *Why it's dead:* Encryption is now table stakes; a protocol daemon that can't speak TLS and instead delegates it to a bolted-on proxy (whose IP it then blindly trusts) is a relic of pre-Snowden, pre-commercial-ISP networking.\n\n**7. UDP \"ping\" packets to choose which server to link.**\n`s_bsd.c:2967` `setup_ping()` opens a `SOCK_DGRAM` socket; `send_ping()` (`:3027`) fires `PING_CPING` datagrams at peer servers and `check_ping()` (`:3068`) times the round trip — `rtt = (tv.tv_sec - pi.pi_tv.tv_sec)*1000 + ...` — then computes a link preference with `d = pow(d, 20.0)` weighting packet loss and stores `aconf->pref` (`s_bsd.c:3105`). Servers probe each other over raw UDP to rank link quality before auto-connecting.\n- *1990s worldview:* Peer servers are directly reachable at fixed IPs, UDP flows freely between them, and hand-rolled RTT sampling is a reasonable way to pick the best backbone path.\n- *Why it's dead:* Firewalls, NAT, and stateful middleboxes drop unsolicited UDP; nobody hand-measures link RTT to pick peers when anycast, BGP, and managed overlays do routing — and an open UDP port that mutates connection logic is now an amplification/attack surface.\n\n**8. SUMMON: the server pages users logged into its Unix host.**\n`s_serv.c:1489` `m_summon()` — under `#ifdef ENABLE_SUMMON` it does `utmp_open()` / `utmp_read()` (`:1522`, `:1530`) to scan the machine's login records, `stat(\"/dev/%s\", ...)` a user's tty (`:1552`), and physically write to their terminal to summon them into IRC. Comment at `s_serv.c:1540`: *\"one we find in utmp. 10/9/90 Spike@world.std.com (loosely based on Jim Frost jimf@saber.com code).\"* Its sibling `USERS` (`m_users`, `s_serv_ext.h:44`) lists who's logged into the host.\n- *1990s worldview:* IRC users *are* shell accounts on the very Unix machine running ircd, so \"go find user bob in utmp and echo to his tty\" is a coherent feature.\n- *Why it's dead:* Clients haven't been shell users on the server host for 25+ years; the command is a security hole (host-user enumeration + tty write) that's been compiled off by default, a fossilized assumption that IRC and Unix logins were the same population.\n\n**9. iauth: a whole child process to hide blocking lookups from the event loop.**\n`iauth/iauth.c` is a separate program the ircd talks to over a pipe (`adfd`, `s_auth.c:590` `sendto_iauth(abuf)`), whose entire reason to exist is that the single `select()` loop cannot afford to block on the slow, hostile checks it performs. Its modules are a museum of 1990s abuse vectors: `mod_socks.c` and `mod_webproxy.c` *connect back to the joining client* to probe for open proxies — `fd = tcp_connect(cldata[cl].ourip, cldata[cl].itsip, SOCKSPORT, ...)` (`mod_socks.c:60`), caching results as `0 = no proxy, 1 = open proxy` (`:41`); `mod_rfc931.c` re-implements ident; `mod_dnsbl.c` does DNS blocklist lookups.\n- *1990s worldview:* Blocking work must be exiled to a helper process because threads aren't an option, and the main abuse to defend against is misconfigured open SOCKS relays.\n- *Why it's dead:* Async runtimes make the \"fork a child to avoid blocking\" architecture obsolete, and actively port-scanning every connecting client for open proxies would today read as hostile behavior, not due diligence.\n\n**10. Access control trusts reverse-DNS hostnames, and K-lines ban by hostname.**\n`s_bsd.c:2912` `check_init()` resolves the server's own name via `gethostbyname()` (`:2923`), and throughout, client access (I-lines/K-lines) is matched against the *resolved hostname* returned by the client's PTR record. K-line comments/reasons are stored in `aconf->passwd` and matched by `match(tmp->passwd, ...)` glob on hostname (`s_conf.c:2242`). The comment at `s_bsd.c:2910` — *\"If hostname gives another name than cname, then check if there is a CNAME record ... accept cname as our name. meLazy\"* — captures the casual trust in whatever DNS says.\n- *1990s worldview:* A hostname is a stable, honest identifier assigned by a trustworthy admin, so glob-matching on `*.mit.edu` is a meaningful access rule.\n- *Why it's dead:* Reverse DNS is attacker-controllable and near-meaningless behind CGNAT/cloud PTR records; identity-by-hostname was replaced by SASL, accounts, and cryptographic auth because DNS trust is forgeable.\n\n**11. IPv6 was retrofitted as `#ifdef` scar tissue over an IPv4 skeleton.**\nThe v4-vs-v6 seams are everywhere: 54 `INET6`/`s6_addr`/`IN_ADDR` hits in `s_bsd.c` alone, 48 in `res.c`, plus `s_auth.c` and `s_conf.c`. Fossils include `static char hostbuf[HOSTLEN+1+100]; /* +100 for INET6 */` (`res.c:33`) — literally padding a buffer by a magic 100 bytes to fit v6 — and the union-y `struct IN_ADDR` typedef papered over `struct in6_addr` with `bcopy(minus_one, ...s6_addr, IN6ADDRSZ)` sentinels (`s_bsd.c:2900`) and dual `getipnodebyname()`/`gethostbyname()` code paths gated on `HAVE_GETIPNODEBYNAME` (`s_bsd.c:2917-2924`).\n- *1990s worldview:* The address is a 32-bit `struct in_addr`; IPv6 is an afterthought bolted on with conditional compilation rather than a first-class type.\n- *Why it's dead:* Modern code uses address-family-agnostic `sockaddr_storage`/`getaddrinfo` from the start; you don't discover your address type with a forest of `#ifdef INET6` and hand-pad buffers \"+100 for INET6.\"\n\n**12.

Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric. Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area. Use when informing product strategy or feature prioritization, building sales battle cards, prepping board or investor materials, or deciding where to differentiate vs. achieve parity.\n- product-management:metrics-review: Review and analyze product metrics with trend analysis and actionable insights. Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence. Use when writing a weekly or monthly status for leadership, announcing a launch, escalating a risk or blocker, or translating the same progress into exec-brief, engineering-detail, or customer-facing versions.\n- product-management:synthesize-research: Synthesize user research from interviews, surveys, and feedback into structured insights. Use when you have a pile of interview notes, survey responses, or support tickets to make sense of, need to extract themes and rank findings by frequency and impact, or want to turn raw feedback into roadmap recommendations.\n- product-management:write-spec: Write a feature spec or PRD from a problem statement or feature idea. Use when turning a vague idea or user request into a structured document, scoping a feature with goals and non-goals, defining success metrics and acceptance criteria, or breaking a big ask into a phased spec.\n- frontend-design:frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts. Distinctive: magenta inverted link hovers, boxy 2px-radius sticker avatars, no gradients except the SponsorCard top rule.\n- xe-go:go-table-driven-tests: Write Go table-driven tests following established patterns.

Also use when the user mentions \"DAO\", \"data access\", \"ORM\", \"database models\", \"GORM\", or is building a Go service that talks to a relational database.\n- xe-go:xe-go-style: Write Go code following the conventions and patterns used in the within.website/x repository, including CLI patterns, error handling, logging with slog, HTTP handlers, and testing.\n- xe-templ:templ-components: Create reusable templ UI components with props, children, and composition patterns. Use when building UI components, creating component libraries, mentions 'button component', 'card component', or 'reusable templ components'.\n- xe-templ:templ-htmx: Build interactive hypermedia-driven applications with templ and HTMX. Use when creating dynamic UIs, real-time updates, AJAX interactions, mentions 'HTMX', 'dynamic content', or 'interactive templ app'.\n- xe-templ:templ-http: Integrate templ components with Go HTTP server using net/http. Use when connecting templ to web server, creating HTTP handlers, mentions 'templ server', 'HTTP routes', or 'serve templ components'.\n- xe-templ:templ-syntax: Learn and write templ component syntax including expressions, conditionals, loops, and Go integration. Use when writing .templ files, learning templ syntax, or mentions 'templ component', 'templ expressions', or '.templ file syntax'.\n- xe-writing:excalidraw-diagrams: Guidelines for creating clean, readable Excalidraw diagrams embedded as inline SVG via JSON data files. Use when creating architecture diagrams, flow diagrams, or any visual documentation.\n- xe-writing:sound-like-a-person: Rewrite prose so it reads like one real person actually said it. Use when text feels constructed, overcorrected, evenly paced, or generically \"well-written\" in the way AI output tends to be. Strips rehearsed phrasing, breaks rhythmic patterns, and restores a clear point of view.\n- xe-writing:xe-writing-style: Transform unstructured notes into polished blog posts in Xe Iaso's voice. Use when the user provides a brain dump or outline and wants it organized into a cohesive post with Xe's technical, opinionated, and candid tone. Also use when editing or reviewing prose that should match Xe's style.\n- ctx-agent-history-search:ctx-agent-history-search: Use ctx to search local coding-agent history before acting. Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current

Each must be respected or the port silently breaks:\n11\t\n12\t- **C-variadic exports** (~14 in `common/send_ext.h`: `sendto_one`, `sendto_flag`, …; plus `irc_sprintf`). Stable Rust cannot *define* `extern \"C\"` variadics.

NOT `-p standalone`.\n14\t- `Peer::link() -> (Peer, burst)` — fake server: sends `PASS linkpass 0211030000 IRC|aHmM` + `SERVER peer.test 1 001B …`, drains the burst through `EOB`.\n15\t- `peer.introduce(nick, uid, user, host, ip, umode, real)` — server-form NICK (UNICK); `uid` must start with `PEER_SID` (\"001B\").\n16\t- `peer.send(\"...\")` / `peer.read_until` / `peer.drain` — raw SID/UID-prefixed server protocol.\n17\t- 14 `golden_s2s_*.rs` tests already exercise message/away/umode/quit/kill/squit/nick/save/userhost/who/register_feed/service/membership (NJOIN add + remote PART, P5x).\n18\t\n19\t**Non-obvious findings that make it deterministic (verified against both binaries):**\n20\t- **Local UIDs are sequential, NOT wall-clock:** first local user = `000AAAAAA` (`curr_cid` starts at 0). So no UID masking is needed — `canonicalize()` is enough as-is.\n21\t- **SID format** (`sid_valid`, s_id.c): exactly 4 chars, first a digit `[0-9]`, rest `[0-9A-Z]`. Server SID `000A`, peer SID `001B`.\n22\t- **`-p standalone` refuses all links** (\"Running in standalone mode\") — but standalone is what lets a local client *create* a `#` channel. In `boot_s2s` a single configured uplink keeps the server permanently **split** (`IsSplit()`), so a local client **cannot create** a federated `#` channel (m_join:2591 → `ERR_UNAVAILRESOURCE`). **BUT** the split guard is inside `if(!chptr)` — a local client **can JOIN an existing** `#` channel.

Committed 2026-06-03 (see [[rust-migration-plan]], detailed in `docs/progress-log/p5.md`).\n\n**How to use it** (in `ircd-golden/src/lib.rs`):\n- `boot_s2s(binary)` — boots against `fixtures/s2s.conf` (adds C/N/H lines authorizing an inbound link from 127.0.0.1, name `peer.test`, pass `linkpass`). NOT `-p standalone`.\n- `Peer::link() -> (Peer, burst)` — fake server: sends `PASS linkpass 0211030000 IRC|aHmM` + `SERVER peer.test 1 001B …`, drains the burst through `EOB`.\n- `peer.introduce(nick, uid, user, host, ip, umode, real)` — server-form NICK (UNICK); `uid` must start with `PEER_SID` (\"001B\").\n- `peer.send(\"...\")` / `peer.read_until` / `peer.drain` — raw SID/UID-prefixed server protocol.\n- 14 `golden_s2s_*.rs` tests already exercise message/away/umode/quit/kill/squit/nick/save/userhost/who/register_feed/service/membership (NJOIN add + remote PART, P5x).\n\n**Non-obvious findings that make it deterministic (verified against both binaries):**\n- **Local UIDs are sequential, NOT wall-clock:** first local user = `000AAAAAA` (`curr_cid` starts at 0). So no UID masking is needed — `canonicalize()` is enough as-is.\n- **SID format** (`sid_valid`, s_id.c): exactly 4 chars, first a digit `[0-9]`, rest `[0-9A-Z]`. Server SID `000A`, peer SID `001B`.\n- **`-p standalone` refuses all links** (\"Running in standalone mode\") — but standalone is what lets a local client *create* a `#` channel. In `boot_s2s` a single configured uplink keeps the server permanently **split** (`IsSplit()`), so a local client **cannot create** a federated `#` channel (m_join:2591 → `ERR_UNAVAILRESOURCE`). **BUT** the split guard is inside `if(!chptr)` — a local client **can JOIN an existing** `#` channel. So the S2S pattern for channel tests (P5x): have the **peer create the channel server-side** (a remote `NJOIN` calls `get_channel(&me, …, CREATE)`), then a local client JOINs it as an observer. Incremental remote joins use **NJOIN** (`:SID NJOIN #chan :@uid`), not JOIN — regular JOIN over S2S is only \"JOIN 0\" / part-all (channel.c:2381).\n- Config is pipe-delimited (`IRCDCONF_DELIMITER '|'`); C/N/H line fields are `host|passwd|name|port|class|`.\n- The IRCnet 2.11 protocol here is UID-based (UNICK/NJOIN/SAVE/EOB), **no SVINFO** exchange.\n\n**Still deferred (no test yet):** multi-hop burst diffing via a TS-aware peer, channel MODE burst (`set_mode`/`send_channel_modes` still C — P5t–P5x ported leaf predicates + invite + can_send + channel_modes + membership; mode/join/part-handler/display clusters remain), `m_ping`/`m_pong` server-col paths (P5i).\n","numLines":27,"startLine":1,"totalLines":27}},"sourceToolAssistantUUID":"a43987cd-744b-4cfe-810e-fd0d67e246a9","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 25 25 + {"parentUuid":"9470216d-3b17-4857-a58f-5a39f9b7897f","isSidechain":true,"agentId":"a7ed96262a7b8aee9","message":{"model":"claude-opus-4-8","id":"msg_01RnRotf9eUbi74PZR74NaSt","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01UXaXTc4LGLU2LtiHuB8fr4","name":"Read","input":{"file_path":"/home/xe/Code/xeiaso.net/ircd.rs/docs/claude-memory/p7-started.md"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":101,"cache_creation_input_tokens":22177,"cache_read_input_tokens":5576,"cache_creation":{"ephemeral_5m_input_tokens":22177,"ephemeral_1h_input_tokens":0},"output_tokens":1,"service_tier":"standard","inference_geo":"not_available"},"diagnostics":null},"requestId":"req_011CchkJmPKZS8Vcgmav97Ry","attributionAgent":"Explore","type":"assistant","uuid":"27f781f0-5e6c-41ec-9468-756d0a9a13a1","timestamp":"2026-07-04T21:43:47.828Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 26 26 + {"parentUuid":"27f781f0-5e6c-41ec-9468-756d0a9a13a1","isSidechain":true,"promptId":"ff7d7d06-784b-477e-af53-645dce495494","agentId":"a7ed96262a7b8aee9","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01UXaXTc4LGLU2LtiHuB8fr4","type":"tool_result","content":"1\t---\n2\tname: p7-started\n3\tdescription: P7 (I/O core + event loop + glue) is COMPLETE as of 2026-06-07 (P7oo ported c_ircd_main, the last C function with logic).

Diagnose a suspected race by re-running the single\nfailing test with a name filter — if it passes alone but fails in the suite, it's this.\n\nRelated: [[l1-cref-static-symbol-limit]], [[piauth-state]] (P7 is the linear next phase).\n","numLines":29,"startLine":1,"totalLines":29}},"sourceToolAssistantUUID":"3876d26d-653b-48b4-8f95-23081d4c314c","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 29 29 + {"parentUuid":"a6cb3588-af0e-4e21-a488-374e8447b21b","isSidechain":true,"agentId":"a7ed96262a7b8aee9","message":{"model":"claude-opus-4-8","id":"msg_01RnRotf9eUbi74PZR74NaSt","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01NnKzRi5hwgSfMjW8rYuQvf","name":"Read","input":{"file_path":"/home/xe/Code/xeiaso.net/ircd.rs/docs/claude-memory/p8-started.md"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":101,"cache_creation_input_tokens":22177,"cache_read_input_tokens":5576,"cache_creation":{"ephemeral_5m_input_tokens":22177,"ephemeral_1h_input_tokens":0},"output_tokens":1,"service_tier":"standard","inference_geo":"not_available"},"diagnostics":null},"requestId":"req_011CchkJmPKZS8Vcgmav97Ry","attributionAgent":"Explore","type":"assistant","uuid":"e9397a96-8de5-4de3-85ae-bac792033d1c","timestamp":"2026-07-04T21:43:49.329Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 30 30 + {"parentUuid":"e9397a96-8de5-4de3-85ae-bac792033d1c","isSidechain":true,"promptId":"ff7d7d06-784b-477e-af53-645dce495494","agentId":"a7ed96262a7b8aee9","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01NnKzRi5hwgSfMjW8rYuQvf","type":"tool_result","content":"1\t---\n2\tname: p8-started\n3\tdescription: \"P8 (delete C + retire oracle) COMPLETE 2026-06-08 (P8u, then P8v deleted the C source tree + ircd-sys); the variadic-trampoline rip-out mechanism + the full done-list\"\n4\tmetadata: \n5\t node_type: memory\n6\t type: project\n7\t originSessionId: b8e14360-5ea1-4ea5-acab-6d8a1784a927\n8\t---\n9\t\n10\t**STATUS: P8 COMPLETE (2026-06-08, P8u — the final sub-phase).** Every ircd C TU is ported;\n11\t**`ircd-sys/build.rs` compiles zero C** (the `make`/`cref_*`/`ctruth.o`/`libircd_c.a`/whole-archive\n12\tlink + `-lz -lm -lcrypt` all dropped — none needed; `pow` resolves from glibc 2.29+). `build.rs`\n13\tnow only runs `configure` + bindgen over the C *headers* (the struct view `ircd-common` still uses\n14\tuntil P9–P12) + expands install-path Makefile vars via a `make_var()` helper.

The L1/L2 oracle is\nmothballed: `ircd-testkit`/`ircd-golden` are `exclude`d from the workspace (git-recoverable, not\ndeleted); `ircd-sys/ctruth.c` + `tests/layout.rs` (the bindgen-vs-real-compile drift-net) deleted.\nFinal differential run was green (L1 all pass; L2 86 pass + only the documented `s_serv_stats`\nreference-C-garbage flake where Rust is correct — [[p5-s2s-stats-flake]]). Gate: `cargo build\n--workspace` 0 warnings links pure Rust; `cargo test --workspace` 698 pass / 0 fail / 125 binaries.\nThe L1 characterization lives on as the `ircd-common/tests/*_snap.rs` insta snapshots ([[ircd-common-snapshot-tests]]).\n\n**P8v (2026-06-08, the literal end of C) DELETED the C source tree AND `ircd-sys` itself.** P8u kept\n`ircd-sys` alive to bindgen the C *headers*; P8v froze that generated `bindings.rs` (4953 lines,\nbindgen 0.72.1, locked config) verbatim into a committed **`ircd-common/src/bindings.rs`** (`pub mod\nbindings;`). **The whole tree's `ircd_sys::bindings::*` / `ircd_sys::MOTD_PATH` paths still resolve\nunchanged** because `ircd-common/src/lib.rs` has `extern crate self as ircd_sys;` + `pub const`\ninstall-path literals (the former `env!`-injected `MOTD_PATH`/`PID_PATH`/`USERLOG_PATH`/`CONNLOG_PATH`/\n`IAUTH_PATH`/`IAUTH`/`SERVER_PATH`/`CONF_PATH`/`TUNE_PATH`/`CONF_PATH_Z`/`TUNE_PATH_Z`, frozen at the\n`/usr/local/...` configure defaults). So **`ircd_sys` is now an alias for `ircd-common` itself** — there\nis no `ircd-sys` crate. `ircd-rs` calls `ircd_common::ircd::c_ircd_main` directly. DELETED: the\n`ircd-sys` crate, the mothballed `ircd-testkit`/`ircd-golden` oracle crates, `iauth-rs/tests/\ndifferential_c.rs`, and ALL C source (`common/ ircd/ iauth/ support/ contrib/ cbuild/ configure\n.clang-format* .github/workflows/clangformat.yml`). Workspace = 5 pure-Rust crates (`ircd-rs`,\n`ircd-common`, `iauth-rs`, `leveva`, `leveva-integration`). **Not one line of C remains in the repo.**\nGate: `cargo build --workspace` 0 warnings (pure-Rust link); `cargo test --workspace` 695 pass / 0 fail.\nCaveat for future work: `bindings.rs` is FROZEN, no longer regenerated — edit it by hand only with\nextreme care (it mirrors the locked configure); the P9–P12 idiomatic passes replace these bindgen types\nwith native Rust field by field.\n\n**Next = P9 (std-lib cleanup), verified against the snapshot suite.** History below.\n\nP8 = the final phase that deletes the last C. At P7 exit only **data globals + ~25\nvariadic sender trampolines** remained (stable Rust can't define `extern \"C\"` variadics).\nP8 replaces each trampoline with a **non-variadic Rust sender API** + converts its call\nsites, then drops all `cc::Build` from `ircd-sys` and mothballs the L1/L2 oracle (tests\nmigrate into `ircd-common`). See [[rust-migration-plan]], [[p7-started]].\n\n**Locked decisions (user, 2026-06-07):** rip out the cleanest trampoline first; build the\nwire line faithfully NOW, adopt **leveva** typed `Message`/identifier newtypes LATER,\nalongside the IRC senders. **Builder choice (P8b):** a `wire!`/`WirePart` **raw-byte** line\nbuilder (in `ircd-common/src/send.rs`) is preferred over `format!` — `format!` goes through\na UTF-8 `String` (lossy on arbitrary comment/kill bytes → byte-diff risk); `wire!` reads C\nstrings as raw bytes (`cstr_bytes`) so user content passes verbatim. (`format!`+lossy `cs`\nis acceptable too, as P8a's `ia_str` did; the user briefly pushed for `format!` then\nretracted — `wire!` is fine.) `wire!` impls cover `&[u8;N]`/`&[u8]`/`*const`/`*mut c_char`/\n`c_int` (`%d`). See [[project-name-leveva-p10]].\n\n**Sender call-graph caveat:** the C variadic senders call EACH OTHER, so a target may not\nbe a graph leaf. Pick a sender with NO live C caller, or pull the coupled C caller(s) into\nthe same rip-out. (P8b: `sendto_ops_butone` was `sendto_serv_butone`'s only in-`send.c`\ncaller → porting serv_butone forced porting ops_butone to avoid an `undefined reference`.)\nCheck with `nm send_link.o | grep <sym>` (defined vs undefined) before scoping.\n\n**The rip-out mechanism (per trampoline):** write a non-variadic Rust core (`fn\nfoo(line: &[u8])` or a typed sender) that does the C body's delivery logic; convert every\nRust caller `foo(c\"fmt %s\", args)` → `foo(format!(\"fmt {}\", …).as_bytes())`; delete the\nvariadic `extern \"C\" { fn foo(…, ...) }` decls; `#ifndef PORT_*_P8x`-guard the C function\n+ add the `-D` to the relevant `*_link.o` compile in `ircd-sys/build.rs`. The cref oracle\nkeeps the unguarded `.o` so `cref_foo` survives for the L1 byte-diff. Faithful-port\ndiscipline still applies (replicate even C bugs; byte-identical wire output).\n\n**Done:**\n- **P8a — `sendto_iauth`** (s_auth.c:120-170). Non-variadic `pub unsafe fn\n sendto_iauth(&[u8])` + `ia_str(*const c_char)->String` in `ircd-common/src/s_auth.rs`;\n 24 call sites (s_auth/s_user/s_bsd/ircd/res). `-DPORT_S_AUTH_SENDTO_IAUTH_P8a`. Cleanest\n first because `nm` showed ZERO live C callers (all in `#ifdef`'d-out bodies). L1\n `sendto_iauth_diff.rs` (socketpair byte-diff).\n- **P8b — `sendto_serv_butone` + `sendto_ops_butone`** (send.c:517/989, the coupled\n server-broadcast pair). Non-variadic `pub unsafe fn sendto_serv_butone(one, body: &[u8])`\n (loop `local[fdas.fd[i]]`, prep ≤510+CRLF, `send_message` each) + `sendto_ops_butone(one,\n from, body: &[u8])` (`:from WALLOPS :body` via serv_butone + `sendto_flag(SCH_WALLOP)`\n still-C). 18 call sites built with `wire!`. `-DPORT_SEND_SERV_BUTONE_P8b`/\n `-DPORT_SEND_OPS_BUTONE_P8b`. L1 `sendto_serv_butone_diff.rs` (parallel `local`/`fdas` vs\n `cref_*` worlds, sendQ byte-diff; QUIT/trunc/uplink-exclusion/WALLOPS); L2-S2S = existing\n `golden_s2s_{away,quit,nick,kill,wallops,membership,join,save,s_serv_connect,squit}`.\n\n- **P8c — `sendto_serv_v`** (send.c:541-572, the `serv_butone` sibling). Same\n `local[]`/`fdas` loop; `ver` param is dead (`#if 0`'d version gate) → always returns 0.\n Non-variadic `pub unsafe fn sendto_serv_v(one, _ver, body: &[u8]) -> c_int` (clones\n serv_butone, reuses `prep_line`); 10 call sites (ircd s_die / channel NJOIN / s_user\n KILL+SAVE / s_serv 4×EOB+SDIE relay+m_sdie) built with `wire!`. NO live C caller → ripped\n out alone. `-DPORT_SEND_SERV_V_P8c`. L1 `sendto_serv_v_diff.rs`; L2-S2S already covered by\n `golden_s2s_{save,join,membership,kill,s_serv_connect,s_serv_squit}`.\n\n- **P8d — `sendto_match_servs` + `sendto_match_servs_v`** (send.c:790-876, the channel-mask\n server-broadcast pair). Same `local[]`/`fdas` loop but: skip `cptr == from` *directly*\n (NOT `one->from`), `&`-leading channel returns at once, and a `chan:server-mask`\n (`get_channelmask` = `libc::strrchr(name,':')`, JAPANESE off) filters recipients via\n `match_`. `_v`'s `ver` gate is dead `#if 0` → always rc = 0. Clean leaves, ripped out as a\n pair; all 12 call sites are in channel.rs (TOPIC/PART/JOIN×2/MODE+o + KICK×3/NJOIN×3/MODE)\n built with `wire!`; cores reuse `prep_line`. `-DPORT_SEND_MATCH_SERVS_P8d`. L1\n `sendto_match_servs_diff.rs` (5 cases incl. the mask-filter inverse); L2-S2S covered by\n existing `golden_s2s_{topic,kick,membership,mode,njoin,join}`.\n\n- **P8e — `sendto_prefix_one`** (send.c:1017-1027, the first `vsendpreprep`-based prefix\n sender). Clean leaf: NO in-send.c caller (internal paths use the `static\n vsendto_prefix_one`; only external now-Rust callers reach the public variadic).\n Introduces the **`prep_preprep` Rust core** = faithful `vsendpreprep` (send.c:388-419,\n IRCII_KLUDGE off): special path (`to && from && MyClient(to) && IsPerson(from)`)\n collapses the `:%s` prefix arg `par` to `:from->name!user@host` when `mycmp(par,\n from->name)==0`, else `:par`; non-special emits `:par`+rest verbatim; reuses `prep_line`.\n Two faithfulness reductions: every caller leads with `:%s` so the C `!strncmp(...,\":%s\",3)`\n guard reduces to the to/from test (caller supplies `par`+pre-formatted `rest`); the\n `from == &anon` disjunct is unreachable from Rust (only still-C channel senders pass\n `&anon`, they keep using C `vsendpreprep`) → encoded only the `mycmp` arm, anon lands\n with those senders. `pub unsafe fn sendto_prefix_one(to, from, par: *const c_char, rest:\n &[u8])`; 10 call sites (s_numeric numeric relay; channel INVITE×2; s_user\n PRIVMSG/NOTICE×4 + KILL) build `rest` with `wire!`. The static `vsendto_prefix_one` +\n `vsendpreprep` STAY C. `-DPORT_SEND_PREFIX_ONE_P8e`. L1 `sendto_prefix_one_diff.rs`\n (collapse / no-collapse / non-special verbatim / >510 trunc; **gotcha:** NUL-terminate\n fixtures before `strcpy` or you overrun `namebuf` → heap corruption — use a bounded\n `set_cstr`); L2 = existing `golden_channel_invite` / `golden_s_user_message` /\n `golden_s2s_message` / `golden_s_user_kill` / `golden_s2s_kill`.\n\n- **P8f — `sendto_match_butone`** (send.c:935-987, the `$$`/`$#`-mask broadcast prefix\n sender). Clean leaf: NO in-send.c caller, ONE call site (`m_message` in s_user.rs).\n REUSES the P8e `prep_preprep`/`sendto_prefix_one` core verbatim — delivery is\n `vsendto_prefix_one(cptr, from, …)` with the **real** `from` (NEVER `&anon`), so no anon\n machinery needed (that's the channel senders' problem). `pub unsafe fn\n sendto_match_butone(one, from, mask, what, par, rest: &[u8])` walks `i=0..=highest_fd`\n over `local[i]`, skip NULL + origin `one`; server recipient → walk `cptr->prev` for first\n `is_registered_user(srch) && srch->from==cptr && match_it(srch,mask,what)`; non-server →\n require client itself match; each survivor → `sendto_prefix_one`. Added `match_it`\n (MATCH_HOST=2→`user->host` array, MATCH_SERVER=1→`user->server` ptr; `match_`==0 on match)\n + `is_registered_user` (= `is_person`). `-DPORT_SEND_MATCH_BUTONE_P8f`. L1\n `sendto_match_butone_diff.rs` (4 cases incl. inverses; **gotcha:** NUL-terminate `mask`/\n `par` fixtures — bare `b\"*.ok\"` overran → `match_` missed); L2 = existing\n `golden_s_user_message`/`golden_s2s_message`.\n\n- **P8g — `sendto_channel_butone` + the `anon` machinery** (send.c:459-510). The channel\n broadcaster + the FIRST anon-needing sender. Ported `anon`/`ausr`/`initanonymous` from C\n to Rust as `#[no_mangle] pub static mut` globals (`MaybeUninit::zeroed`) + an extern-C\n `initanonymous`; the still-C `vsendpreprep`/`sendto_channel_butserv` reference them via\n `extern` decls (guarded by `-DPORT_SEND_ANON_P8g`, replacing the `static` defs with\n `extern`). `prep_preprep` grew the `from == anon_ptr()` collapse arm. The non-variadic\n core routes BOTH the C raw-server (`vsendprep`) and prefixed-MyClient (`vsendpreprep`)\n paths through the P8e `sendto_prefix_one` core — byte-identical because `prep_preprep`\n already branches on `my_client(to)` (server → else-path `:par`, MyClient → collapse; a\n local STAT_CLIENT always has `user` so the MyConnect-non-eligible case is never MyClient).\n 7 call sites (s_numeric/channel×5/s_user) build `rest` with `wire!`.\n `-DPORT_SEND_CHANNEL_BUTONE_P8g`. L1 `sendto_channel_butone_diff.rs` (parallel\n Rust/cref channels — channel passed by arg, no global; 4 cases: broadcast\n collapse/verbatim/IsMe-skip, `one` exclusion+inverse, self-send-not-doubled, anon-channel\n collapse; **gotchas:** cref's global `sendbuf`/`psendbuf` + `anon` globals → `GLOBALS_LOCK`\n serialize; `STAT_ME == -1` not -2); L2 = channel join/part/kick/topic/mode_set/invite +\n s_user_message + s2s message/join/kick/topic/mode.\n\n- **P8h — `sendto_common_channels`** (send.c:620-729, the local-channel-peers broadcaster\n for NICK/QUIT). Clean leaf, NO C caller, **no anon** (skips anonymous channels → `from`\n always the real `user`). Key faithfulness call: C preps the line ONCE (`if (!len)`,\n DEBUGMODE off) into `psendbuf` + reuses it for all recipients → ported as a local\n `[u8;520]` + `len`, calling `prep_preprep` only when `len==0`, NOT `sendto_prefix_one` per\n recipient (which re-preps against each `to`) — matters in the big-client branch where a\n remote (`fd==-1`, not MyClient) `clist` member still receives the cached FIRST-recipient\n line. Both Comstud branches ported (`highest_fd<50` HUB `IsMember`-over-`user->channel` +\n the `>=50` `clist`/`sentalong` walk). `sentalong` is a per-call `vec![0;MAXCONNECTIONS]`\n indexed via raw `.offset((*cptr).fd as isize)` (matches C's `fd==-1` OOB pointer arith, no\n Vec panic). New private `is_member`/`is_quiet` (via P2 `find_channel_link`). `pub unsafe fn\n sendto_common_channels(user, par: *const c_char, rest: &[u8])`; 3 call sites (s_misc\n exit_client QUIT; s_user nick-save + m_nick NICK) → par + `wire!` rest.\n `-DPORT_SEND_COMMON_CHANNELS_P8h` (the now-unused `sentalong` static guarded too). L1\n `sendto_common_channels_diff.rs` (parallel rust/cref `local[]`+`highest_fd` worlds w/\n per-client `user->channel` Link lists, 4 cases: shared-channel broadcast+self-send+inverse,\n quiet-skip, anon-skip, remote-user no-self-send; `GLOBALS_LOCK` serializes); L2 =\n `golden_s_user_nick`/`golden_s_user_quit` + S2S `golden_s2s_nick`/`golden_s2s_quit`.\n\n- **P8i — `sendto_flog` + `logfiles_open`/`logfiles_close` + the `userlog`/`connlog` fd\n statics** (send.c:1202-1440). The FIRST **non-variadic** leaf — `void sendto_flog(cptr,\n char msg, username, hostname)`. Ported the whole connected component over the shared\n file-private fds (the logger + its open/close pair + the two statics) to\n `ircd-common/src/send.rs`; `setup_svchans`/`svchans` (a *separate* component shared with\n the still-C variadic `sendto_flag`) stay C. **Formatting = byte-identical by\n construction:** `libc::sprintf` with the exact C format string `\"%c %d %d %s %s %s %s %d\n %s %lu %llu %lu %llu \"` + args cast to C's varargs promotions (`%c`/`%d`→`c_int`,\n `%lu`→`c_ulong`, `%llu`→`c_ulonglong`, `(u_int)firsttime`/`(u_int)timeofday` via `as u_int\n as c_int`) — same libc engine + same fmt ⇒ no logic to drift. Config: `LOG_OLDFORMAT`/\n `USE_SYSLOG`/`USE_SERVICES`/`LOG_SERVER_CHANNELS`/`LOGFILES_ALWAYS_CREATE` all OFF (only the\n new-format `#else` + the `logfile==-1` early-return + a no-`O_CREAT` open compile).\n `FNAME_USERLOG`/`FNAME_CONNLOG` reach Rust via new `IRCD_USERLOG_PATH`/`IRCD_CONNLOG_PATH`\n rustc-envs (the `PID_PATH` make-expand trick) → `ircd_sys::{USERLOG_PATH,CONNLOG_PATH}`\n consts. `-DPORT_SEND_FLOG_P8i`. L1 `sendto_flog_diff.rs` = the **write_pidfile pattern**:\n both worlds open the same hardcoded log path so drive open→flog→close in rust+cref, read\n back, assert identical bytes; sandbox `/usr/local/var/log` is unwritable → both no-op\n (`None==None`), bytes pinned only where writable. **No L2/S2S** — file-only, `USE_SERVICES`\n off → never on the wire; boot smoke via any golden (`logfiles_open` runs at every boot).\n 1 live `sendto_flog` caller (s_bsd `add_connection` clone-reject).\n\n- **P8j — `sendto_flag` (the keystone) + `dead_link`** (send.c:1141/50). The server-notice\n broadcaster, ~220 call sites across 16 files → non-variadic `sendto_flag(chan, body: &[u8])`\n that clamps `chan`, looks up the now-Rust `svchans[]` (connected component `svchans` +\n `setup_svchans` ported too) and wraps `:me NOTICE <chname> :<body>` via the still-C variadic\n `sendto_channel_butserv`. `dead_link` (its last C caller) ported alongside. WirePart grew\n `%u`/`%08x`/`%x`/`%X`/`%#x`/`%02d`/`%2d`/`%c`/`%p` newtypes (`Hex08`/`Hex`/`HexUp`/`HexAlt`/\n `Dec02`/`Dec2`/`Chr`/`Ptr`); integers via `format!` (byte-identical), `%#x`/`%p` via libc.\n `-DPORT_SEND_FLAG_P8j -DPORT_SEND_DEAD_LINK_P8j`. L1 `sendto_flag_diff.rs` (4) + 16 golden.\n\n- **P8k — `sendto_channel_butserv`** (send.c:746-780, the channel local-members broadcaster).\n Unblocked once P8j made `sendto_flag` (its only in-send.c caller) Rust. A clean leaf like P8g\n minus the server broadcast: only ever reaches MyClient members → constant `lfrm` → the\n per-recipient P8e `sendto_prefix_one` core is byte-identical to the C `psendbuf`/`if(!len)`\n cache (no cache to replicate). `pub unsafe fn sendto_channel_butserv(chptr, from, par, rest)`;\n 14 call sites (12 channel.rs, 1 s_misc anon-PART, the sendto_flag wrapper). Its now-orphaned\n statics `vsendpreprep` + `vsendto_prefix_one` + the `psendbuf` buffer go with it under the\n same guard (channel_butserv was their last unguarded caller); `vsendprep`/`sendbuf` stay live\n (`vsendto_one`); the `anon`/`ausr` externs stay (harmless). `-DPORT_SEND_CHANNEL_BUTSERV_P8k`.\n L1 `sendto_channel_butserv_diff.rs` (4 cases — local+inverse/quiet/anon/remote; the anon case\n needs `initanonymous`+`cref_initanonymous` to populate both worlds' separate `anon` so\n `IsPerson(&anon)` holds) + 14 golden (channel + s2s) byte-identical.\n\n- **P8l — `sendto_one` (THE KEYSTONE)** (send.c:450-468). The single-client sender behind\n ~every numeric reply; 435 call sites across 15 ircd-common files. Non-variadic core\n `pub unsafe fn send::sendto_one(to, body: &[u8]) -> c_int` = `vsendprep` (libc-`vsprintf`\n ≤510 trunc + CRLF into a local `[u8;520]`) + `send_message`. Two call-site builders: `wire!`\n for the 58 `c\"...\"` literal sites; a NEW `reply_one!(to, fmt, args...)` macro (send.rs) for\n the 377 `reply(...)`/runtime-pattern sites — renders via libc `snprintf` into a 2048-byte buf\n then hands the C string to the core. The 2 `rlen += sendto_one(...)` (channel.rs) call the\n core directly. Guarded `-DPORT_SEND_ONE_P8l` (sendbuf+vsendprep+vsendto_one+sendto_one).\n Converted by a 15-agent per-file ultracode workflow (edit-only, central verify). L1\n `sendto_one_diff.rs` (5 cases, GLOBALS_LOCK for the cref_sendbuf/dbuf-freelist race) + full\n 111-test golden byte-identical bar the 2 known [[p5-s2s-stats-flake]] STATS garbage flakes.\n\n **KEY CORRECTION to the earlier \"blocked on leveva typed-numerics (P10)\" claim:** that\n overstated it. `reply(i)` with a CONSTANT `i` (the ~430 `reply(ERR_X)` sites) has a\n compile-time-known format — NOT runtime. Only ~6 sites are genuinely-runtime `reply(var)`\n (`reply(num)`/`reply(cj)`/`reply(rpl)`/`reply(tmp_rpl)`/`reply(REPORT_ARRAY[idx][1])`). And\n the delivery path `vsendprep` formats via **libc `vsprintf`** (NOT the custom `irc_vsprintf`),\n so the `reply_one!`/`snprintf` bridge is byte-identical for ALL sites incl. the runtime ones.\n ⇒ sendto_one was rippable NOW via wire!+snprintf, no P10 numeric layer needed. The idiomatic\n leveva-`Numeric` conversion of the reply sites stays P11. See [[project-name-leveva-p10]].\n\n- **P8m — the `esendto_*` cluster** (ircd/s_send.c — the LAST variadic sender trampolines, the\n UID-aware service-routing senders `esendto_one`/`esendto_serv_butone`/`esendto_channel_butone`/\n `esendto_match_servs` + the `esend_message`/`build_old_prefix`/`build_new_prefix`/`build_suffix`\n machinery + 4 buffers/6 length ints). USE_SERVICES OFF → **ZERO callers** in both C and Rust →\n no call-site conversion, **no L2 path** (L1 is the gate). Faithful non-variadic\n `ircd-common/src/s_send.rs`: variadic `fmt,...`→`suffix: &[u8]`; `:%s %s %s` prefixes via\n `libc::sprintf` (byte-identical incl. glibc `(null)` for the NULL `oname` build_new_prefix can\n pass — same libc-for-format-semantics call as P8j/P8l); all quirks replicated (maxplen+slen>512\n suffix truncation, UID-selection + newplen=-1 bail, hardcoded `:anonymous!…` local prefix,\n &-channel return + match() mask filter; loop-index decrement placed to keep C `for(;i--)` under\n `continue`). The 4 senders are plain `pub unsafe fn` (NOT extern \"C\": `&[u8]` not FFI-safe, zero\n callers). **`s_send.o` dropped OUTRIGHT** (added to `PORTED`, no `s_send_link.o`, no `-DPORT_*` —\n cref keeps the unguarded .o in CREF_OBJS for L1). L1 `s_send_diff.rs` 9/9 (branches+inverses) +\n golden_registration byte-identical. Done via a 5-agent ultracode workflow (1 impl + 3 adversarial\n faithfulness audits, all \"faithful\" / 0 findings + 1 golden smoke).\n\n**ALL variadic sender trampolines are now Rust (P8a–P8m).** (The P8l-era \"all senders done\" note\nwas wrong — it missed s_send.c's `esendto_*`; P8m closed that.) P8 then turned to the residual C\n**data globals** (NON-sender):\n\n- **P8n — the `s_auth.c` iauth data globals (the FIRST data-global drop) → `s_auth.o` dropped\n outright.** `nm --defined-only s_auth_link.o` showed it defined ONLY the five iauth globals\n (`iauth_options` u_char / `iauth_spawn` u_int / `iauth_version` char* / `iauth_conf`/`iauth_stats`\n bindgen-`LineItem*`) + module-private `rcsid` (every fn already `-DPORT_S_AUTH_*`-guarded out\n P7u..P8a). Moved them to Rust-owned `#[no_mangle] pub static mut` statics in\n `ircd-common/src/s_auth.rs` (zero/NULL-init = the C BSS defs). **DATA-symbol seam = the\n function-symbol seam:** the OTHER modules (ircd.rs/s_user.rs/s_bsd.rs) keep their\n `ircd_sys::bindings::iauth_options`/`iauth_spawn` imports — those bindgen `extern \"C\" { static mut … }`\n *decls* resolve to the Rust *defs* at link (proven for hundreds of fns + for data via `anon`/`ausr`\n P8g, `svchans` P8j). **Surgery confined to s_auth.rs itself:** you MUST drop the colliding\n `use ircd_sys::bindings::iauth_options` + the two local `extern \"C\"` decls (iauth_conf/stats + the\n separate iauth_version block) and reference the new module defs (else same-module name clash).\n build.rs: `s_auth.o`→`PORTED` (no `s_auth_link.o`; deleted the whole `-DPORT_S_AUTH_*` second-compile\n step + the dead `… => \"s_auth_link.o\"` map-arm); cref keeps unguarded `s_auth.o` for L1. **Gate for a\n pure-data drop (no behavioral L1 diff of the globals themselves):** lean on the existing differentials\n that exercise them end-to-end — `read_iauth_diff` is load-bearing (drives Rust `read_iauth`, which\n mutates all five, vs `cref_read_iauth`) + iauth_reporters/sendto_iauth/start_iauth diffs + `nm` (all 5\n = Rust BSS, none `U`) + `golden_registration`. 0 warnings.\n\n- **P8o — `send.o` dropped outright (the second data-global drop, the trivial one P8n flagged).**\n `send.c` is now FULLY ported: over P3d + P8b..P8l every sender + `dead_link` + the `sendto_flog`\n logfile cluster + the `svchans`/`setup_svchans` component + the `anon`/`ausr`/`initanonymous`\n machinery were `#ifdef`'d out of `send_link.o` and reimplemented in `ircd-common/src/send.rs`,\n leaving `nm --defined-only cbuild/send_link.o` = just `rcsid` (lowercase `r`, internal-linkage\n static version string, unreferenced). So `send.o`→`PORTED`; deleted the whole `send_link.o`\n second-compile `run(make … --eval=…)` step + the `-DPORT_SEND_P3 .. -DPORT_SEND_ONE_P8l` guard\n chain + the `\"send.o\" => \"send_link.o\"` link-map arm in build.rs. cref keeps the unguarded `send.o`\n for the L1 send oracle. The Rust `logfiles_open` still reads FNAME_* via the IRCD_*_PATH rustc-envs\n (unaffected). **Gate for a pure inert-drop:** the existing 14 send L1 differentials (57 tests,\n zero-diff) + `golden_registration` (2) byte-identical + `nm` (logfiles_open/svchans = Rust defs,\n no undefined send symbols). 0 warnings. (`sendto_one`/`sendto_flag` are now plain Rust `fn`s, not\n C-ABI symbols, so they don't appear in `nm` — their callers are all Rust.)\n\n- **P8p — `s_bsd.o` dropped outright (the third data-global drop).** All of s_bsd.c's *logic* went\n Rust over P7d..P7ff; `nm --defined-only s_bsd_link.o` then showed it defined ONLY the event-loop\n data globals (`local` aClient*[MAXCONNECTIONS=50] / `fdas`/`fdall` FdAry / `highest_fd`/`readcalls`\n int / `udpfd`/`resfd`/`adfd` int=-1 / `timeofday` time_t / `mysk` sockaddr_in6, P7s-de-static'd) +\n module-private `rcsid`.

All ircd logic\nAND data is Rust.\n\n- **P8t — `version.c` ported to Rust (the LAST *generated* C TU) → `version.o` no longer built.**\n `version.c` (generated by `ircd/version.c.SH`) is pure data: `generation`/`creation`/`pass_version`\n (char*), `infotext[]` (char*[], NULL-term), `isupport` (char**, runtime-filled) + private `rcsid`.\n NOT in `CREF_OBJS` (it was archived straight into `libircd_c.a`) → no `cref_*`, no L1 differential.\n Moved all five to `#[no_mangle] pub static mut` in new `ircd-common/src/version.rs` (+\n `VERSION_LINK_ANCHOR` in `lib.rs::link_anchor`); DATA-symbol seam (= P8n–q): consumers\n (`s_serv` m_info walks `infotext`; `s_user` RPL_CREATED; `s_debug`/`s_bsd`) keep their\n `ircd_sys::bindings::*` extern refs → resolve to the Rust defs at link. `infotext`'s bindgen decl\n is incomplete `[*mut c_char; 0]`; the real len (46) lives only in the Rust def, walked via\n `addr_of!`. **Version sourcing (user-directed): crate metadata at build time** — `generation` =\n `env!(\"CARGO_PKG_VERSION\")`, `creation` = `env!(\"IRCD_BUILD_CREATION\")` from a NEW\n `ircd-common/build.rs` (formats `SystemTime::now()` to the C-like `Wkd Mon D YYYY at HH:MM:SS UTC`\n shape, dependency-free Hinnant civil-from-days, UTC, pinned via lone `rerun-if-changed=build.rs`).\n `pass_version` = bindgen `PATCHLEVEL` const; `infotext[]` copied verbatim. build.rs: deleted the\n `version.c.SH` gen step + the `version.o` compile + `ar.arg(\"version.o\")` → `libircd_c.a` is now\n `ctruth.o`-only. **Canonicalizer:** `creation` is now genuinely build-time volatile (ref-C\n version.o stamp vs Rust crate-metadata stamp differ), so added a 003 RPL_CREATED mask to\n `ircd-golden::canonicalize` (`:This server was created <MASKED>`) — the analogue of the existing\n 371 Birth-Date mask. No `.snap` captures the value (the `s_err` replies table holds the static\n format *template* `\":%s 003 %s :This server was created %s\"`, unaffected). Gate: 0 warnings; `nm`\n all 5 = Rust D/B none `U`, `version.o` absent (`ar t` = ctruth.o only); `ircd-common` snapshots\n green; golden 58 pass + the 1 known [[p5-s2s-stats-flake]].\n\n- **P8s — all 115 L1 `cref_` differentials migrated to self-contained `ircd-common` `insta`\n snapshot tests** (the \"migrate load-bearing tests\" item). Each `ircd-testkit/tests/<n>_diff.rs`\n now has an `ircd-common/tests/<n>_snap.rs` driving ONLY the Rust port (`#[no_mangle]` syms via\n `ircd_common::link_anchor()`; NO `cref_`, NO `ircd_testkit`). `insta = \"1\"` added as a dev-dep.\n **Soundness = the capture chain:** step 0 confirms the matching differential is green (Rust==cref)\n BEFORE capturing, so `snapshot==cref` golden — the reference-C correctness is frozen forward with\n no C oracle. Dual-World diffs collapse to a single Rust world over the same corpus/branches/inverses.\n **Determinism rules:** NEVER snapshot raw pointers/addresses/timestamps/fd-numbers/ephemeral-ports/\n HashMap-order; self/interior-pointer asserts → derived invariants (bool `name==namebuf`, offsets,\n list-walk sequences, buffer bytes); keep clock interposition + global `Mutex`es.

This was the PLAN.md P12 entry condition.\n- **Deleted crates:** `ircd-common`, `ircd-rs`, `iauth-rs` (the C-iauth oracle,\n long since subsumed by native [[iauth-subsumed-into-leveva]] `leveva-iauth`), and\n `leveva-integration` (the differential pin crate — retires with its oracle; its\n guarantees were already carried by leveva's self-contained 212-file golden +\n proptest suite, and leveva/leveva-iauth had ZERO Cargo/`use` dep on the deleted\n crates).\n- **Deployment rigging deleted (user ask):** `docker/Dockerfile.ircd`, the `ircd`\n target in `docker-bake.hcl`, and all of `docs/k8s/` (the example network existed\n only to demo the now-impossible leveva↔ircd S2S link).\n- **Docs (user ask):** rewrote `README.md` (now describes leveva, the finished\n strangler's product) and fixed stale present-tense `ircd-*` references in\n `leveva/src/lib.rs` + the two Cargo.toml comments.\n\n**Workspace was `leveva` + `leveva-iauth` ONLY at P12.** Gate met: `cargo build\n--workspace` 0 warnings, `cargo clippy --workspace --tests` clean, `cargo test -p\nleveva -p leveva-iauth` green.\n\n**UPDATE 2026-06-21 — leaf crates extracted.** The workspace is no longer just\nthose two: the most self-contained, runtime-free modules are being carved out into\ntheir own crates (user-requested refactor):\n- **`leveva-message`** — the RFC 1459 / IRCv3 wire `Message` + builder + parser\n (`leveva-message/src/lib.rs`, was `leveva/src/message.rs`). Generic over `impl\n Display`, so no typed-id/runtime dep; deps = std + unicode-segmentation + serde.\n- **`leveva-patricia`** — the generic safe Patricia trie (`leveva-patricia/src/lib.rs`,\n was `leveva/src/patricia.rs`). std-only, zero coupling.\n- **`leveva-casemap`** — RFC 1459 case folding (`leveva-casemap/src/lib.rs`, was\n `leveva/src/casemap.rs`). Imports only `core` (Ordering + Hasher); the *lowest*\n leaf — `string`/`ident`/`matching`/`channel`/`registry`/`whowas` depend on it, it\n on nothing. Shipped with a 7-property **proptest fuzz** module (fold⇔eq, cmp⇔eq,\n antisymmetry, hash-agrees-with-eq, fold idempotent+UTF-8-safe, high-byte identity)\n — proptest is the stable fuzz tier (no nightly/cargo-fuzz here, same as message).\n- **`leveva-string`** — casemapping-aware `IrcStr`/`IrcString`/`IrcStringBuilder`\n (`leveva-string/src/lib.rs`, was `leveva/src/string.rs`). The architectural #2 leaf:\n now that `casemap` is a crate, `string` depends on exactly one workspace crate\n (`leveva-casemap`) + std, while `ident`/`channel`/`registry`/`whowas` depend on it.\n Shipped with a 6-property **proptest fuzz** module (eq lifts casemap, Ord\n consistent+antisymmetric, hash-agrees-with-eq, `Borrow<IrcStr>` round-trip,\n validation soundness, builder≡try_from).\n\n- **`leveva-cidr`** — pure CIDR network-mask helpers\n (`parse_cidr`/`contains`/`network_base`/`cidr_match`; `leveva-cidr/src/lib.rs`, was\n `leveva/src/cidr.rs`). A **pure** leaf: **zero** workspace deps (only `std::net`).\n This corrected the prior survey's claim that `matching`+`cidr` were \"mutually\n referential\" — `cidr`'s references to `matching`/`connlimit` are doc-comment-only;\n the real edge is one-way `matching` → `cidr`. Extracting `cidr` therefore **unblocks\n `matching`** (its only intra-crate deps are now `casemap` + `cidr`, both crates).\n Shipped with a 10-property **proptest fuzz** module (parse round-trip + out-of-range\n reject, contains reflexive-through-network_base, network_base idempotent, contains\n prefix-monotone, `/0` universal + full-length exact, family mismatch never contains,\n `cidr_match ≡ parse + contains`).\n- **`leveva-cloak`** (2026-06-22) — the deterministic FNV-keyed `+x` hidden-host\n transform (`cloak`/`cloak_ip`/`cloak_host`; `leveva-cloak/src/lib.rs`, was\n `leveva/src/cloak.rs`).

read all 25 files. Here is my ranked list of blog-post candidates, filtered for a systems audience that's already tired of \"AI ported C to Rust.\"\n\n---\n\n## Tier 1 — the strongest stories\n\n**1. Freezing the clock froze the whole server (the counterintuitive determinism trap)**\nThe written test plan said the obvious thing: to make golden tests deterministic, `LD_PRELOAD` a shim overriding `time()`/`gettimeofday()` to a fixed value. Doing it *breaks the daemon entirely*. A frozen `time()` freezes the global `timeofday` (reset every loop iteration at `ircd.c:1250`), so the io_loop's scheduler never advances and **the listen socket is never serviced** — clients just hang, never accepted. The tell was in `strace`: `poll()` was only watching the resolver fd. The fix was the inverse of intuition: keep the *real* clock and mask the handful of time-bearing output tokens (numerics 242 uptime, 317 idle/signon, 391 time) in a canonicalizer instead. This is a great \"the fix for nondeterminism is NOT to remove time\" lede.\nSource: `p0-l2-golden-harness.md`\n\n**2. The oracle was garbage: two 1990s varargs bugs the reference C emits and the Rust doesn't**\nThe whole project trusts the C as an oracle — except in two STATS paths the C emits pure garbage and the Rust port is *correct*, which inverts the entire testing premise. (a) `report_myservers` (STATS m) prints an uninitialized peer sendq for a freshly-bursting link: `…recv 3544950785030750208kB sq…` vs Rust's `0kB sq`. (b) STATS t (`s_misc.c:1079`) formats three `u_int` (4-byte) counters `is_cklQ/is_ckly/is_cklno` with `%lu` (8-byte), so the still-C variadic `sendto_one` `va_arg`s 4 bytes of *adjacent call-frame garbage*: `281470681743360Sq/…` vs Rust's `0Sq`. A width-mismatch printf bug that's been latent since 1997, surfaced only because a byte-exact Rust twin existed to disagree with it. Forces the essay's best question: what do you do when your source-of-truth is provably wrong? (Answer: note it, don't \"fix\" the snapshot, defer to when the variadic sender is replaced.)\nSource: `p5-s2s-stats-flake.md`\n\n**3. Running two versions of the same program in one process via `objcopy` symbol renaming**\nThe L1 differential harness is genuinely clever and generalizes. To diff the Rust port against the C function-by-function *in the same test binary*, the build does `nm -g --defined-only` over the C objects → builds a rename map `<sym> → cref_<sym>` → `objcopy --redefine-syms` on a copy of each `.o` → `ar crDs` into `libcref.a`. Now `match` (Rust's `#[no_mangle]`) and `cref_match` (the C original) coexist at distinct addresses and you assert they agree over a corpus. ~450 symbols across 31 objects. The sharp-edge follow-ups are just as good: (a) `objcopy` only renames *global* symbols, so any `static` C function has no `cref_` twin and simply can't be L1-tested (hit on `lookup_confhost`, static in `s_conf.c`) — you fall back to a golden test of a caller; (b) an integration test made only of raw `extern` blocks references no Rust item, so rustc drops the rlib and *every* C symbol goes undefined at link — you need a `link_anchor()` that touches a real Rust item to pin the archive.\nSource: `p0c-l1-harness-constraints.md`, `l1-cref-static-symbol-limit.md`\n\n**4. The variadic wall: what stable Rust literally cannot do, and how it shaped the whole port**\nStable Rust cannot *define* an `extern \"C\"` variadic function. IRCnet's entire output layer is variadic `sendto_*`/`esendto_*`, and worse, `vsendpreprep` consumes `va_arg` *per recipient* while walking the member list — so there's no \"format once, hand a string to Rust\" reduction available. Consequence: ~25 sender trampolines stayed as C until the very last phase, and \"100% Rust\" was a stated end-goal, not a mid-migration property. The eventual rip-out has a subtle systems detail worth the post: they rejected `format!` for building wire lines because it routes through a UTF-8 `String` and is **lossy on arbitrary bytes** in kill/quit comments (→ byte-diff failures against the oracle). They built a `wire!` raw-byte line builder (`cstr_bytes`) so user content passes verbatim, later growing printf-faithful newtypes (`Hex08`, `Dec02`, `%p` via libc) to stay byte-identical.\nSource: `ircd-migration-hazards.md`, `p3-transport-format.md`, `p8-started.md`\n\n## Tier 2 — strong, more specialized\n\n**5. bindgen silently degrades structs to opaque byte-blobs — for two invisible reasons**\nFuture phases depend on `offset_of!` over 14 structs, and bindgen will quietly emit `pub struct X { _address: u8 }` (breaking every offset) under two non-obvious conditions. (a) bindgen defaults to **C++**, and these 1990s headers use `class` as a struct *field name* (`class_def.h:25`) and the `register` storage class — both C++ errors; clang's C++ error-recovery leaves the struct incomplete. Fix: force `-x c`. (b) bindgen 0.70 mishandles the libclang-22 AST for structs forward-declared as `typedef struct X Y;` (Client/User/Server/Channel…), picking the forward decl over the real definition; 0.72 fixes it. The diagnostic ritual — `grep -c 'pub _address: u8,'` should be 0 — plus a \"layout drift-net\" that emits bindgen's sizes/offsets as *compile-time* `const` assertions checked against a C compile of `offsetof`. Practical FFI war story for anyone bindgen-ing old C.\nSource: `p0b-bindgen-constraints.md`\n\n**6. The double strangler, and deliberately throwing away the \"make it idiomatic\" phase**\nThe meta-architecture is the interesting part: the C tree was the oracle for a faithful *mechanical* Rust port; then that verified port became the oracle for a from-scratch *idiomatic* daemon (`leveva`); then both got deleted at parity. The load-bearing decision (2026-06-08) was **retiring P9 entirely** — the phase that would have cleaned up the mechanical port in place (`MyMalloc`→`Box`, freelist→owned, `libc`→`std`). Rationale: \"an oracle only needs to keep building and passing its tests; it does not need to be idiomatic,\" and that crate is deleted at parity anyway, so polishing it earns nothing. A crisp argument about where refactoring effort is and isn't worth spending during a migration.\nSource: `leveva-pivot-p9-retired.md`, `p12-complete.md`\n\n**7. IRC's own flood protection sabotaged the test harness**\nA rich testing-determinism war story. The daemon's fake-lag (anti-flood penalty) throttle makes scripted golden tests flaky: the penalty clock runs ahead of wall-clock, the server *stops reading the socket*, and reads time out (60s vs 11s runs). Both the `client_packet` recvQ gate and the `read_packet` re-arm gate must be bypassed — disabling only one leaves the socket unread. The deeper follow-up is the best bit: a golden test failed *deterministically* 3/3, and the root cause was that three `NAMES` whole-table scans cost +4 penalty each at the harness's 50ms pacing → the client's command clock ran ~21s ahead of the 10s `MAX_PENALTY` → the serve loop *parked* that client's read arm. A separate case: polling `WHOIS` every 300ms to keep a connection alive tripped the >60s excess-flood *kill*, closing the socket → `BrokenPipe` on the next write. The lesson (deterministic `read_until` \"no NNN\" panic = fakelag parking, not load) is a genuine debugging-taxonomy insight.\nSource: `test-fakelag-disabled.md`, `golden-read-until-timeout-flake.md`\n\n**8. 1990s memory micro-optimizations that make \"no moves\" a correctness requirement in Rust**\nTwo intertwined hazards. `aClient` has **interior self-pointers**: `make_client` sets `cptr->name = cptr->namebuf` (`list.c:121`), and `me` is a by-value global with `client = &me`. Move or copy that struct by value in Rust and the self-pointer dangles — so it's raw-pointers-only, everywhere, and the idiomatic pass has to unwind it. Paired with the `CLIENT_REMOTE_SIZE` trick (`struct_def.h:577`): remote clients are deliberately allocated only `offsetof(aClient, count)` bytes to save memory, so touching the local-only tail of a struct when `from != self` is a straight out-of-bounds read. A concrete illustration of how a 30-year-old RAM-saving hack dictates the shape of the safe-Rust rewrite.\nSource: `ircd-migration-hazards.md`, `p2-data-lookup.md`\n\n## Tier 3 — good supporting anecdotes / sidebars\n\n**9. Port the compiled ABI, not the header — and replicate the bugs on purpose**\nFaithful-port discipline produced several sharp findings. `dbuf_copy` is declared in `dbuf_ext.h` but *commented out* in `dbuf.c` — no symbol, no callers, no `cref_` oracle; porting it would have invented behavior. Rule: match the compiled ABI (7 dbuf fns), not the header (8). Meanwhile `match()` has an always-active `MAX_ITERATIONS 512` DoS cap whose `#ifdef` guard is unconditionally true — the Rust *must* reproduce the `calls++ > 512 → return 1` early-out. And `irc_memcmp` is reimplemented as a plain byte compare because only the *sign* of the result is contractually observed (test asserts `.signum()`). Good material on \"faithful\" being a precise, sometimes counterintuitive contract.\nSource: `p1-leaf-utils.md`\n\n**10. `static mut` globals race across cargo's parallel test threads (with a vivid symptom)**\nA whole class of test-isolation bugs: process-global `static mut` state (`me`, `local[]`, `highest_fd`, hash tables, an oper-flag conversion buffer) is one shared instance, and cargo runs `#[test]`s on parallel threads. The signature symptom is great copy: oper-flag letters scramble under load — `LKSClhdrRDeTqPpt` intermittently renders as `t`, or `-`→`K`. Diagnosis heuristic worth stating: *passes alone, fails in the suite = shared-global race*; fix is a file-level serializing `Mutex`. The L1 analogue of the L2 `PORT_LOCK`.\nSource: `p7-l1-shared-global-race.md`, `s-conf-oline-snap-flake.md`, `p2-data-lookup.md`\n\n**11. Char signedness and a dead-code linker failure — 1990s portability macros biting back**\nTwo same-day host-portability gotchas. `c_char` is `i8` on x86_64 but `u8` on aarch64, so an L1 test that declared its buffers `[0i8; 64]` only compiled on x86 (4× E0308 on aarch64); the fix is to always type C-char buffers as `c_char`. Separately, `support_diff` failed to *link* with `undefined reference to cref_irc_memcmp` — because `irc_memcmp` is wrapped in `#if defined(HAVE_MEMCMP) && defined(MEMCMP_BROKEN)`, and configure decided this host's memcmp is fine (`MEMCMP_BROKEN` undefined), so the function is dead code with no symbol to rename. A nice illustration of configure-era conditional compilation surfacing as a modern Rust link error.\nSource: `s-user-umode-diff-broken.md`, `support-irc-memcmp-host-gated.md`\n\n**12. The standalone-server paradox in S2S testing**\nWeird-protocol-behavior sidebar. A lone server with one configured uplink is permanently *split* (`IsSplit()`), so a local client **cannot create** a `#` channel (`m_join:2591` → `ERR_UNAVAILRESOURCE`) — but the split guard sits inside `if(!chptr)`, so it *can* JOIN a channel that already exists. The workaround shaped the whole S2S test strategy: have the fake peer create the channel server-side via `NJOIN` (`get_channel(&me, …, CREATE)`), then have the local client join it as an observer. Also notable: incremental remote joins use `NJOIN`, not `JOIN` — plain `JOIN` over S2S only ever means \"JOIN 0\"/part-all (`channel.c:2381`).\nSource: `p5-s2s-golden-harness.md`, `boot-golden-harness.md`\n\n---\n\n**Honorable mentions** (small, could be one-liners or sidebars, probably not their own post): `myncmp` does its end-of-string check *after* advancing pointers → OOB read on the empty string with n≥2, found just by reading the C carefully (`p0c`); `replies[]` had to be *dumped from the compiled oracle*, not text-extracted, because of `#if` config branches and an escaped `\\r\\n` at entry 384 that would CRLF-normalize away if pasted (`p3`); `alphabet_id[256]` is only 249-entry-initialized in C so indices 249–255 default to 0, reproduced verbatim (`p3`); DNS reverse-PTR lookup was disabled project-wide (`-DNO_DNS_LOOKUP`) because it was both nondeterministic *and* held registration across loop iterations (`p0-l2`); NUL-terminate fixtures before `strcpy` or you overrun `namebuf` into heap corruption (`p8` P8e).\n\nOne framing note for the human: items 1, 2, 3, 4, and 7 are the ones a jaded systems reader hasn't seen before — they're specific to *differentially testing a port* and to *1997 C's runtime behavior*, not to \"AI\" or \"Rust\" generically.

Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric. Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts.

Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests).

`ircd-common` oracle at the *live command* level (not just\n12\tleaf functions like the older differentials).\n13\t\n14\t**Harness:** `leveva-integration/tests/native_oracle/mod.rs` (a subdir module, so cargo doesn't\n15\ttreat it as a test binary). `world()` boots `ircd_common::boot::boot` **once per test binary**\n16\tbehind a `OnceLock` (standalone + noiauth, `IRCD_TEST_CONFIG` → `tests/fixtures/minimal.conf`,\n17\tholding the shared `flock` port lock the `ircd-rs` goldens use — port 16667). `OracleClient` drives\n18\tit over real loopback TCP; `LevevaWorld`/`LevevaClient` mirror the API in-memory via\n19\t`Session::feed`. The **skeleton** = ordered 3-digit numeric reply codes (`numeric_codes`), dropping\n20\tnon-numeric MODE/NOTICE broadcasts (leveva `:nick!user@host` vs oracle `:server` is a by-design\n21\tdivergence excluded from the comparison).\n22\t\n23\t**Two load-bearing harness rules (cost real time, don't undo):**\n24\t- **`oracle_lock()`** — a process-global mutex every oracle-driving test must hold for its *whole\n25\t body*. cargo runs a binary's `#[test]`s on parallel threads; the oracle is one single-threaded\n26\t select loop, so concurrent clients make a reply lag past `drain`'s idle window → short skeleton →\n27\t spurious mismatch. Passes with `--test-threads=1`, fails parallel without the lock.\n28\t- **`read_until` ignores per-read timeouts** (waits for the sentinel up to a 5s hard deadline); the\n29\t oracle's io-loop can flush a client's registration burst *after* `connect()`'s first reads.\n30\t\n31\t**MODE differential findings:** leveva and IRCnet-2.11 agree on the bulk of MODE behavior; exactly\n32\t**4 documented divergences** (all leveva-native-design or leveva-stricter, not bugs): `+O`\n33\t(leveva oper-only-join per [[leveva-channel-mode-rework-slice77]] vs oracle 472), a second `+k`\n34\tover an existing key (leveva 467 vs oracle silent), `-a`/`-r` clearing a removed flag (leveva 472\n35\tvs oracle silent; `+a`/`+r` *set* agrees at 472), `+l` with no arg (oracle 461 vs leveva lenient).\n36\tThese are excluded from the fuzz alphabet and asserted both-directions in the curated table.\n37\t\n38\t**To add another command differential:** new `tests/<cmd>_skeleton_differential.rs` + a\n39\t`<cmd>_skeleton_proptest.rs`, both `mod native_oracle;`, lock with `oracle_lock()`, compare\n40\t`OracleClient::skeleton` vs `LevevaClient::skeleton`. Follows the [[leveva-slice-recording]]\n41\tcadence. See [[leveva-next-step-s2s-completeness]] / the testing plan §4 for the remaining\n42\tfuzzing gaps.\n43\t\n44\t**Slice 93 (2026-06-11) extended it to JOIN/PART/KICK** (channel membership). Full agreement\n45\ton the whole gate+error surface (475/471/473/474, 403/442/482/441/401/461 + inverses); the\n46\tfaithful `m_kick` emits 442/482 exactly as leveva. **2 documented divergences:** `JOIN 0`\n47\t(oracle parts-all → empty vs leveva 403) and `+O` oper-only-join ([[leveva-channel-mode-rework-slice77]]:\n48\tleveva 520; the oracle can't build a +O channel, so leveva-only assertion).\n49\t\n50\t**Two load-bearing harness rules slice 93 added (don't undo):**\n51\t- **A dropped `OracleClient` reaps its user.** It owns the `TcpStream`; dropping it closes the\n52\t socket → the oracle sees EOF → reaps that client. A test needing a victim/bystander to *stay*\n53\t must **retain its handle** for the whole test (e.g. `KickWorld._victim_o`), else a later\n54\t command targeting it spuriously returns 401/no-such.\n55\t- **The fixture caps connections per IP via the class Y-line CIDR fields.** `minimal.conf`'s\n56\t `Y|10|90||100|512000|<L1.N1>|<L2.N2>|` last two fields = `<cidr_len>.<max_clients>`\n57\t (ENABLE_CIDR_LIMITS on). They were `10.2|32.2` → only **2** clients per /32 → a 3rd\n58\t simultaneous client got `ERROR :… (Too many user connections (local))` (empty skeleton /\n59\t BrokenPipe). Raised to `10.100|32.100` (100/IP). Any test opening 3+ simultaneous oracle\n60\t clients depends on this.\n61\t\n62\t**Slice 94 (2026-06-11) extended it to the read-only info/query cluster** (WHOIS/WHO/NAMES/LIST/\n63\tTOPIC), the observe-side companion to slice 93. No harness changes. Full agreement on NAMES,\n64\tWHO targets, the **whole** TOPIC surface (incl. `332 333` set — the oracle *does* emit 333; a\n65\treply-code grep misses it, so ground-truth with a live probe before locking assertions), and\n66\tWHOIS-ghost. **4 documented divergences (both-direction asserted):** LIST's leading `321\n67\tRPL_LISTSTART` (leveva emits, oracle drops the obsolete numeric → `&leveva[1..] == oracle`);\n68\tbare `WHO` (oracle 461 vs leveva lists 352…315); WHOIS `317` idle (oracle-only — leveva ==\n69\toracle minus 317); bare `WHOIS` (oracle 461 vs leveva 431). **Not exercised** (unreachable over\n70\tplaintext in-process): the `320` collision (oracle RPL_WHOISTLS vs leveva RPL_WHOISEXTRA/websocket)\n71\t+ leveva-only 335 bot / 276 certfp.\n72\t\n73\t**Slice 95 (2026-06-11) extended it to PRIVMSG/NOTICE delivery** — the **first slice to CLOSE a\n74\tdivergence** instead of documenting it (the user said \"make leveva behave the same way\"). A probe found\n75\tleveva diverged only on **missing parameters**: the oracle's PRIVMSG/NOTICE `msgtab` rows carry\n76\t**min-params = 2** (`parse.rs:176,189`), so its *parser* emits `461 ERR_NEEDMOREPARAMS` before\n77\t`m_message` runs for any short input — the C handler never emits the RFC `411`/`412`. (An empty trailing\n78\t`PRIVMSG nick :` doesn't count toward parc → also `461`.) leveva used RFC `411`/`412`/silence. **Fix:**\n79\t`leveva/src/command/message.rs::message()` now returns `461` via `need_more_params` for a missing/empty\n80\ttarget *or* text, for **both** verbs, **ungated by `errs`** (the `461` is parser-level, so NOTICE's\n81\tno-auto-reply rule — which still governs `401`/`404`/`407` — does not suppress it). `411`/`412` stay\n82\tdefined + still used by leveva-native `TAGMSG` (no oracle counterpart → out of parity scope). Collateral\n83\tre-pinned: message.rs unit tests (`…_461`), `notice_delivers_but_never_replies` (bare/no-text NOTICE now\n84\t`461`), `mod.rs` comment, `help/NOTICE.md`, `leveva/tests/privmsg_proptest.rs` (PRIVMSG `401|461`, NOTICE\n85\t`461`-only). Agreeing surface (broad): live/ghost nick + channel, AWAY `301` (PRIVMSG-only), `+n`/`+m`\n86\t`404`, six-ghost dedup+cap `[401×5,407]` (`MAX_TARGETS==5`/`MAXPENALTY==10`), non-oper `$$` mask → `401`.\n87\t\n88\t**Slices 96–99 (2026-06-11) CLOSED four more divergences** — a review of the differential tests vs\n89\t`docs/rfcs/` (driven by the user's **standing rule below**) turned three previously *documented*\n90\tdivergences + one untested gap into convergence assertions. Done via an **ultracode Workflow**\n91\t(investigate→adversarially-verify-vs-RFC/oracle→synthesize→sequential TDD implement→gate):\n92\t- **96 `JOIN 0`** (was slice-93 \"leveva 403\") → leveva now parts all channels per RFC 2812 §3.2.1\n93\t (exact sole-token `\"0\"` gate before validation, reusing the PART machinery; empty skeleton on both).\n94\t- **97 WHOIS `317 RPL_WHOISIDLE`** (was slice-94 \"oracle-only\") → `ClientRecord` gained `signon` +\n95\t `last_activity` (unix nanos, seeded at `try_claim`); only the sender's own PRIVMSG bumps it\n96\t (faithful to the oracle's `IDLE_FROM_MSG`, where only `m_private` advances `user.last`); WHOIS\n97\t emits 317 as the last per-target line before 318, **gated on a local target** (`is_local_uid` =\n98\t the oracle's `my_connect`). Remote targets omit it.\n99\t- **98 `MODE +l` no-arg** (was the 4th MODE divergence above, \"leveva lenient\") → now `461`\n100\t (`ModeReq::NeedParam`); a present-but-non-numeric `+l <x>` *stays* a silent drop (the oracle's\n101\t `atoi`-0 break), so don't 461 that.\n102\t- **99 welcome-burst `253 RPL_LUSERUNKNOWN`** → a per-`ServerContext` half-open `IntGauge`\n103\t (`note_unknown` at accept in main.rs; `clear_unknown` exactly-once via a `Session.counted_unknown`\n104\t flag, **after** the welcome snapshot so a lone client still reports `253 <nick> 1` like the oracle).\n105\t `252 RPL_LUSEROP` stays correctly suppressed (opers hardcoded 0) until a live oper gauge lands —\n106\t its `if opers>0` conditional is already correct and will light up automatically.\n107\t\n108\t**THE STANDING RULE (user feedback, load-bearing for P11→P12):** *if `ircd-common` (the oracle)\n109\tsupports something but leveva does NOT, that is a **bug** in leveva — close it, don't document it.*\n110\tThis is stronger than the slice-95 lesson: it covers leveva doing **less** than the oracle (missing\n111\t317, no `JOIN 0`, lenient `+l`, dropped 253), not just picking a different numeric. Reserve\n112\t\"documented divergence\" ONLY for genuinely leveva-native behavior (`+O` oper-only-join, IRCv3,\n113\twebsocket/TLS numerics) or where **leveva is the RFC-correct side and the oracle is the quirky one**\n114\t(bare `WHO` → leveva lists per RFC 2812 §3.6.1 vs oracle 461; second `+k` → leveva 467 ERR_KEYSET;\n115\tLIST leading `321`; bare WHOIS → leveva 431) — those stay as leveva-stricter/correct, NOT bugs.\n116\t\n117\t**Remaining documented divergences after 96–99** (still open, both genuinely leveva-native or\n118\tleveva-correct): `+O` oper-only-join; the `320` collision (RPL_WHOISTLS vs RPL_WHOISEXTRA) + 335/276\n119\t(unreachable over plaintext); bare `WHO`/`WHOIS` + second `+k` + `-a`/`-r` + LIST `321` (leveva-correct).\n120\t\n121\t**Slice 100 (2026-06-11) extended it to the read-only LOOKUP cluster** — `WHOWAS`/`USERHOST`/`ISON`\n122\t(`lookup_skeleton_differential.rs` + `lookup_skeleton_proptest.rs`, no harness change). A\n123\t**characterization slice — no leveva source change**: full agreement on the whole surface\n124\t(WHOWAS history→`[314,312,369]` / unknown→`[406,369]` / comma-mix→`[314,312,406,369]` / count-param\n125\taccepted / live-never-renamed→`[406,369]`; USERHOST/ISON present(self)/absent(ghost)→one `[302]`/`[303]`;\n126\tbare USERHOST/ISON→`[461]`). **Whowas-history seam = a synchronous NICK change** (both daemons file\n127\tthe OLD nick to the ring on rename — no socket-drop/reap timing dependency; far cleaner than dropping\n128\ta handle). **1 documented divergence (NOT closed):** bare `WHOWAS` → oracle `461` (generic msgtab\n129\tmin-params=1 fires in the parser before `m_whowas`) vs leveva `431` — leveva is RFC-2812-correct (the\n130\toracle's own `m_whowas` parc<2 branch *also* intends 431, just preempted), same family as bare\n131\t`WHOIS`/`WHO`. Proptest agreeing surface is **history-free** (USERHOST/ISON token lists + all-ghost\n132\tWHOWAS comma lists → `[406×N,369]`) so no flaky per-case ring-building over TCP.\n133\t\n134\t**Slice 101 (2026-06-11) extended it to the SERVER-INFO cluster** — `VERSION`/`TIME`/`ADMIN`/\n135\t`INFO`/`LUSERS`/`USERS`/`MOTD` (`server_info_skeleton_differential.rs` + `_proptest.rs`). The\n136\t**first server-info slice to CLOSE a bug** via the standing rule: every one of these verbs honors\n137\tthe oracle's `hunt_server` `<target>` arg — an **unknown** target server → `402 ERR_NOSUCHSERVER`\n138\t— but leveva ignored the target and answered locally. Closed with a shared resolver\n139\t`leveva/src/command/hunt.rs` (`resolve`→`Hunt::{Local,NoSuchServer}`: None/empty or glob-match of\n140\tthe local name → Local; else NoSuchServer) wired at the `command/mod.rs` dispatch site via a\n141\t`local_query(ctx,nick,msg,target_idx,answer)` wrapper — **target_idx=0** for VERSION/TIME/ADMIN/\n142\tINFO/USERS/MOTD, **=1** for STATS (selector then target) / LUSERS (mask then target). **Remote-peer\n143\tforward DEFERRED** (no info-query S2S forward yet → a peer target also 402s; unreachable in the\n144\tsingle-world harness, documented in hunt.rs). Collateral: `time.rs`/`users.rs` \"ignores-arguments\"\n145\ttests flipped to \"unknown_target_is_402\". **3 documented divergences kept** (leveva-native/correct,\n146\tNOT bugs): VERSION appends its own `005 RPL_ISUPPORT` block after 351 (modern superset; oracle emits\n147\t005 only at registration → `oracle==leveva[..1]`); INFO body length (leveva's modern block vs\n148\t`infotext[]`, shape `371…374` agrees); `LUSERS <mask>` single-arg (oracle filters counts, drops\n149\t265/266; leveva ignores the mask → full block — arg0 is a mask not a target, so no 402).\n150\t**Harness change (don't undo):** `LevevaWorld::new()` now seeds a non-empty `admin` block (mirrors\n151\tthe fixture A-line) so ADMIN compares fairly — an empty block 423s. **Local-target case rule:** there\n152\tis NO shared local name (oracle `irc.test` vs leveva `leveva.test`), so the local-name inverse drives\n153\teach daemon with ITS OWN name.\n154\t\n155\tNext differential cluster: ask the user (OPER/STATS admin mutate-side, AWAY/presence signalling,\n156\tor the S2S burst/netsplit skeleton). A natural follow-on to slice 101 is the **info-query S2S forward**\n157\t(make a `<target>` naming a linked peer actually forward, lighting up the deferred path).\n158\t\n159\t**Slice 102 (2026-06-11) extended it to the S2S BURST + NETSPLIT** — the first slice to diff a\n160\t*link-accepting* in-process oracle over the server-to-server wire. New infra, all in\n161\t`leveva-integration/tests/`:\n162\t- `native_oracle_s2s/mod.rs` — a SIBLING of `native_oracle` that boots a SECOND embedded\n163\t `ircd-common` `Prot::Off` (clears `BOOT_PROT|BOOT_STRICTPROT` → accepts links; Standalone\n164\t refuses) against a NEW `fixtures/s2s.conf` (N+C line pair + single client/server P-line on\n165\t **16668**), behind its OWN `OnceLock` world + `oracle_lock_s2s()` + a DISTINCT flock\n166\t (`ircd-rs-golden-s2s.port.lock`). Must be its OWN test binary (one embedded `Server`/process;\n167\t the slice-92 standalone world can't coexist). `link_peer()` = a raw PASS/SERVER driver.\n168\t- `verb_skeleton()` — the S2S analogue of `numeric_codes`, INVERTED: keep S2S verbs\n169\t (PASS/SERVER/UNICK/NICK/NJOIN/SJOIN/MODE/SAVE/EOB/EOBACK/SQUIT/QUIT/KILL/ENCAP), DROP numerics,\n170\t line-buffer, strip `:prefix`.\n171\t- `s2s_support/mod.rs` — the leveva side is a real SUBPROCESS (FORCED: `Session::feed` is\n172\t client-only, never reaches `s2s::dispatch`; leveva routes server-vs-client by the listener\n173\t `server-only` flag at accept). Boots the real `leveva` binary (located via `current_exe()` —\n174\t `CARGO_BIN_EXE_leveva` is leveva-crate-only) on `s2s.kdl` (server-only port 16701) + a copied\n175\t `Peer`.\n176\t\n177\t**Three empirical findings (don't re-learn the hard way):** (1) the PASS version token MUST be\n178\tthe IRCnet patchlevel `0211030000` — `get_version` (s_serv.rs:3815) rejects the leveva-lenient\n179\t`2.11` as `SV_OLD` → \"Server version is too old\"; leveva accepts any, so the SAME bytes drive\n180\tboth. (2) A local CHANNEL can NEVER be in the *outbound* burst — a lone protocol-mode oracle is\n181\t`is_split()` (`iconf.split=1` at boot, never cleared since `split_minservers/minusers` are\n182\tunconfigured `-1`) and a split server refuses to CREATE a `#` (channel.rs:2816). So burst\n183\tsymmetry seeds a local USER ONLY → both daemons burst exactly `[PASS, SERVER, UNICK, EOB]`.\n184\tNJOIN agreement is proven by a PEER-bursted channel + a local client JOINing the now-EXISTING\n185\tchannel (chptr non-null skips the split-create block). (3) The discrete `EOBACK` (hopcount 1)\n186\tarrives AFTER the peer sends its OWN `EOB`. (4) Re-linking the N/C-line name (`peer.test`) races\n187\tthe prior link's EOF teardown → link the oracle ONCE per binary (the netsplit half is its own\n188\tbinary with a fresh world).\n189\t\n190\t**Verdict:** FULL AGREEMENT — both burst `[PASS,SERVER,UNICK,EOB]` + discrete `EOBACK`, both\n191\trelay a `QUIT` on peer SQUIT (401-unreachable inverse). The design's UNICK-vs-NICK /\n192\tNJOIN-vs-SJOIN \"divergence\" was a confusion of IRCnet (UNICK/NJOIN) with Undernet/TS6 — caught\n193\tby the design workflow's adversarial reviewer, corrected to agreement. Per THE STANDING RULE: NO\n194\tclose-the-bug item; the lone divergence is leveva sending ONLY the channel `QUIT` to co-members\n195\t(no oper split WALLOPS) = leveva-native/RFC-correct.\n196\t\n197\t**Slices 103–107 (workflow batch, 2026-06-11)** extended the skeleton differential to the\n198\tremaining client clusters: 103 AWAY/INVITE/`+i`-join, 104 NICK errors/collision, 105 registration\n199\terrors (CLOSED too-short USER/PASS→461), 106 SUMMON (CLOSED →411/445/402), 107 LINKS/MAP/TRACE\n200\t(CLOSED `LINKS <remote>`→402). See `docs/progress-log/p11.md`.\n201\t\n202\t**Slice 108 (2026-06-11) extended it to the OPER + privileged-command GATE cluster** —\n203\tOPER/KILL/WALLOPS/CONNECT/SQUIT/DIE/RESTART/REHASH (`oper_gate_skeleton_differential.rs` +\n204\t`_proptest.rs`, no harness change). Both daemons are **oper-less** (no O-line / empty `operators`)\n205\t→ the gate differential: every privileged command refused identically. **CLOSED two leveva\n206\tordering bugs** per the standing rule: the oracle routes a non-oper to `m_nopriv` (481) BEFORE the\n207\thandler's param check, so a bare `CONNECT`/`SQUIT` from a non-oper is **481, not 461** — leveva's\n208\t`connect.rs`/`squit.rs` checked params first (inconsistent with their own KILL/DIE/RESTART/REHASH\n209\twhich already gate privilege first). Fix = move the `OperPrivilege` gate ahead of the param/target\n210\tcheck in both; an oper still gets 461 for a genuinely missing target. **1 documented divergence\n211\t(leveva-RFC-correct):** non-oper `WALLOPS` → oracle silently drops via `m_nop` (empty skeleton) vs\n212\tleveva `481 ERR_NOPRIVILEGES` (RFC 2812 §3.4.7).

(An empty trailing\n`PRIVMSG nick :` doesn't count toward parc → also `461`.) leveva used RFC `411`/`412`/silence. **Fix:**\n`leveva/src/command/message.rs::message()` now returns `461` via `need_more_params` for a missing/empty\ntarget *or* text, for **both** verbs, **ungated by `errs`** (the `461` is parser-level, so NOTICE's\nno-auto-reply rule — which still governs `401`/`404`/`407` — does not suppress it). `411`/`412` stay\ndefined + still used by leveva-native `TAGMSG` (no oracle counterpart → out of parity scope).

Done via an **ultracode Workflow**\n(investigate→adversarially-verify-vs-RFC/oracle→synthesize→sequential TDD implement→gate):\n- **96 `JOIN 0`** (was slice-93 \"leveva 403\") → leveva now parts all channels per RFC 2812 §3.2.1\n (exact sole-token `\"0\"` gate before validation, reusing the PART machinery; empty skeleton on both).\n- **97 WHOIS `317 RPL_WHOISIDLE`** (was slice-94 \"oracle-only\") → `ClientRecord` gained `signon` +\n `last_activity` (unix nanos, seeded at `try_claim`); only the sender's own PRIVMSG bumps it\n (faithful to the oracle's `IDLE_FROM_MSG`, where only `m_private` advances `user.last`); WHOIS\n emits 317 as the last per-target line before 318, **gated on a local target** (`is_local_uid` =\n the oracle's `my_connect`). Remote targets omit it.\n- **98 `MODE +l` no-arg** (was the 4th MODE divergence above, \"leveva lenient\") → now `461`\n (`ModeReq::NeedParam`); a present-but-non-numeric `+l <x>` *stays* a silent drop (the oracle's\n `atoi`-0 break), so don't 461 that.\n- **99 welcome-burst `253 RPL_LUSERUNKNOWN`** → a per-`ServerContext` half-open `IntGauge`\n (`note_unknown` at accept in main.rs; `clear_unknown` exactly-once via a `Session.counted_unknown`\n flag, **after** the welcome snapshot so a lone client still reports `253 <nick> 1` like the oracle).\n `252 RPL_LUSEROP` stays correctly suppressed (opers hardcoded 0) until a live oper gauge lands —\n its `if opers>0` conditional is already correct and will light up automatically.\n\n**THE STANDING RULE (user feedback, load-bearing for P11→P12):** *if `ircd-common` (the oracle)\nsupports something but leveva does NOT, that is a **bug** in leveva — close it, don't document it.*\nThis is stronger than the slice-95 lesson: it covers leveva doing **less** than the oracle (missing\n317, no `JOIN 0`, lenient `+l`, dropped 253), not just picking a different numeric. Reserve\n\"documented divergence\" ONLY for genuinely leveva-native behavior (`+O` oper-only-join, IRCv3,\nwebsocket/TLS numerics) or where **leveva is the RFC-correct side and the oracle is the quirky one**\n(bare `WHO` → leveva lists per RFC 2812 §3.6.1 vs oracle 461; second `+k` → leveva 467 ERR_KEYSET;\nLIST leading `321`; bare WHOIS → leveva 431) — those stay as leveva-stricter/correct, NOT bugs.\n\n**Remaining documented divergences after 96–99** (still open, both genuinely leveva-native or\nleveva-correct): `+O` oper-only-join; the `320` collision (RPL_WHOISTLS vs RPL_WHOISEXTRA) + 335/276\n(unreachable over plaintext); bare `WHO`/`WHOIS` + second `+k` + `-a`/`-r` + LIST `321` (leveva-correct).\n\n**Slice 100 (2026-06-11) extended it to the read-only LOOKUP cluster** — `WHOWAS`/`USERHOST`/`ISON`\n(`lookup_skeleton_differential.rs` + `lookup_skeleton_proptest.rs`, no harness change). A\n**characterization slice — no leveva source change**: full agreement on the whole surface\n(WHOWAS history→`[314,312,369]` / unknown→`[406,369]` / comma-mix→`[314,312,406,369]` / count-param\naccepted / live-never-renamed→`[406,369]`; USERHOST/ISON present(self)/absent(ghost)→one `[302]`/`[303]`;\nbare USERHOST/ISON→`[461]`). **Whowas-history seam = a synchronous NICK change** (both daemons file\nthe OLD nick to the ring on rename — no socket-drop/reap timing dependency; far cleaner than dropping\na handle). **1 documented divergence (NOT closed):** bare `WHOWAS` → oracle `461` (generic msgtab\nmin-params=1 fires in the parser before `m_whowas`) vs leveva `431` — leveva is RFC-2812-correct (the\noracle's own `m_whowas` parc<2 branch *also* intends 431, just preempted), same family as bare\n`WHOIS`/`WHO`. Proptest agreeing surface is **history-free** (USERHOST/ISON token lists + all-ghost\nWHOWAS comma lists → `[406×N,369]`) so no flaky per-case ring-building over TCP.\n\n**Slice 101 (2026-06-11) extended it to the SERVER-INFO cluster** — `VERSION`/`TIME`/`ADMIN`/\n`INFO`/`LUSERS`/`USERS`/`MOTD` (`server_info_skeleton_differential.rs` + `_proptest.rs`). The\n**first server-info slice to CLOSE a bug** via the standing rule: every one of these verbs honors\nthe oracle's `hunt_server` `<target>` arg — an **unknown** target server → `402 ERR_NOSUCHSERVER`\n— but leveva ignored the target and answered locally. Closed with a shared resolver\n`leveva/src/command/hunt.rs` (`resolve`→`Hunt::{Local,NoSuchServer}`: None/empty or glob-match of\nthe local name → Local; else NoSuchServer) wired at the `command/mod.rs` dispatch site via a\n`local_query(ctx,nick,msg,target_idx,answer)` wrapper — **target_idx=0** for VERSION/TIME/ADMIN/\nINFO/USERS/MOTD, **=1** for STATS (selector then target) / LUSERS (mask then target). **Remote-peer\nforward DEFERRED** (no info-query S2S forward yet → a peer target also 402s; unreachable in the\nsingle-world harness, documented in hunt.rs). Collateral: `time.rs`/`users.rs` \"ignores-arguments\"\ntests flipped to \"unknown_target_is_402\". **3 documented divergences kept** (leveva-native/correct,\nNOT bugs): VERSION appends its own `005 RPL_ISUPPORT` block after 351 (modern superset; oracle emits\n005 only at registration → `oracle==leveva[..1]`); INFO body length (leveva's modern block vs\n`infotext[]`, shape `371…374` agrees); `LUSERS <mask>` single-arg (oracle filters counts, drops\n265/266; leveva ignores the mask → full block — arg0 is a mask not a target, so no 402).\n**Harness change (don't undo):** `LevevaWorld::new()` now seeds a non-empty `admin` block (mirrors\nthe fixture A-line) so ADMIN compares fairly — an empty block 423s. **Local-target case rule:** there\nis NO shared local name (oracle `irc.test` vs leveva `leveva.test`), so the local-name inverse drives\neach daemon with ITS OWN name.\n\nNext differential cluster: ask the user (OPER/STATS admin mutate-side, AWAY/presence signalling,\nor the S2S burst/netsplit skeleton). A natural follow-on to slice 101 is the **info-query S2S forward**\n(make a `<target>` naming a linked peer actually forward, lighting up the deferred path).\n\n**Slice 102 (2026-06-11) extended it to the S2S BURST + NETSPLIT** — the first slice to diff a\n*link-accepting* in-process oracle over the server-to-server wire. New infra, all in\n`leveva-integration/tests/`:\n- `native_oracle_s2s/mod.rs` — a SIBLING of `native_oracle` that boots a SECOND embedded\n `ircd-common` `Prot::Off` (clears `BOOT_PROT|BOOT_STRICTPROT` → accepts links; Standalone\n refuses) against a NEW `fixtures/s2s.conf` (N+C line pair + single client/server P-line on\n **16668**), behind its OWN `OnceLock` world + `oracle_lock_s2s()` + a DISTINCT flock\n (`ircd-rs-golden-s2s.port.lock`). Must be its OWN test binary (one embedded `Server`/process;\n the slice-92 standalone world can't coexist). `link_peer()` = a raw PASS/SERVER driver.\n- `verb_skeleton()` — the S2S analogue of `numeric_codes`, INVERTED: keep S2S verbs\n (PASS/SERVER/UNICK/NICK/NJOIN/SJOIN/MODE/SAVE/EOB/EOBACK/SQUIT/QUIT/KILL/ENCAP), DROP numerics,\n line-buffer, strip `:prefix`.\n- `s2s_support/mod.rs` — the leveva side is a real SUBPROCESS (FORCED: `Session::feed` is\n client-only, never reaches `s2s::dispatch`; leveva routes server-vs-client by the listener\n `server-only` flag at accept). Boots the real `leveva` binary (located via `current_exe()` —\n `CARGO_BIN_EXE_leveva` is leveva-crate-only) on `s2s.kdl` (server-only port 16701) + a copied\n `Peer`.\n\n**Three empirical findings (don't re-learn the hard way):** (1) the PASS version token MUST be\nthe IRCnet patchlevel `0211030000` — `get_version` (s_serv.rs:3815) rejects the leveva-lenient\n`2.11` as `SV_OLD` → \"Server version is too old\"; leveva accepts any, so the SAME bytes drive\nboth. (2) A local CHANNEL can NEVER be in the *outbound* burst — a lone protocol-mode oracle is\n`is_split()` (`iconf.split=1` at boot, never cleared since `split_minservers/minusers` are\nunconfigured `-1`) and a split server refuses to CREATE a `#` (channel.rs:2816). So burst\nsymmetry seeds a local USER ONLY → both daemons burst exactly `[PASS, SERVER, UNICK, EOB]`.\nNJOIN agreement is proven by a PEER-bursted channel + a local client JOINing the now-EXISTING\nchannel (chptr non-null skips the split-create block). (3) The discrete `EOBACK` (hopcount 1)\narrives AFTER the peer sends its OWN `EOB`. (4) Re-linking the N/C-line name (`peer.test`) races\nthe prior link's EOF teardown → link the oracle ONCE per binary (the netsplit half is its own\nbinary with a fresh world).\n\n**Verdict:** FULL AGREEMENT — both burst `[PASS,SERVER,UNICK,EOB]` + discrete `EOBACK`, both\nrelay a `QUIT` on peer SQUIT (401-unreachable inverse). The design's UNICK-vs-NICK /\nNJOIN-vs-SJOIN \"divergence\" was a confusion of IRCnet (UNICK/NJOIN) with Undernet/TS6 — caught\nby the design workflow's adversarial reviewer, corrected to agreement. Per THE STANDING RULE: NO\nclose-the-bug item; the lone divergence is leveva sending ONLY the channel `QUIT` to co-members\n(no oper split WALLOPS) = leveva-native/RFC-correct.\n\n**Slices 103–107 (workflow batch, 2026-06-11)** extended the skeleton differential to the\nremaining client clusters: 103 AWAY/INVITE/`+i`-join, 104 NICK errors/collision, 105 registration\nerrors (CLOSED too-short USER/PASS→461), 106 SUMMON (CLOSED →411/445/402), 107 LINKS/MAP/TRACE\n(CLOSED `LINKS <remote>`→402). See `docs/progress-log/p11.md`.\n\n**Slice 108 (2026-06-11) extended it to the OPER + privileged-command GATE cluster** —\nOPER/KILL/WALLOPS/CONNECT/SQUIT/DIE/RESTART/REHASH (`oper_gate_skeleton_differential.rs` +\n`_proptest.rs`, no harness change). Both daemons are **oper-less** (no O-line / empty `operators`)\n→ the gate differential: every privileged command refused identically. **CLOSED two leveva\nordering bugs** per the standing rule: the oracle routes a non-oper to `m_nopriv` (481) BEFORE the\nhandler's param check, so a bare `CONNECT`/`SQUIT` from a non-oper is **481, not 461** — leveva's\n`connect.rs`/`squit.rs` checked params first (inconsistent with their own KILL/DIE/RESTART/REHASH\nwhich already gate privilege first). Fix = move the `OperPrivilege` gate ahead of the param/target\ncheck in both; an oper still gets 461 for a genuinely missing target. **1 documented divergence\n(leveva-RFC-correct):** non-oper `WALLOPS` → oracle silently drops via `m_nop` (empty skeleton) vs\nleveva `481 ERR_NOPRIVILEGES` (RFC 2812 §3.4.7). Agreeing: OPER no-params→461 / `OPER name pass`\nno-O-line→491 (host arm, not 464); KILL/DIE/RESTART/REHASH→481 every arity.\n\n**Slice 110 (2026-06-11) — info-query S2S FORWARD — first slice to CLOSE a *forwarding* bug.**\nClosed the deferred remote half of `command/hunt.rs` (slice 101 closed only unknown-target→402).\nThe oracle's `hunt_server` (`ircd-common/src/s_user.rs:4501`) forwards `VERSION`/`TIME`/`ADMIN`/\n`INFO`/`STATS`/`LUSERS`/`MOTD`/`USERS` with a `<target>` naming a remote server to the next hop,\nand the answering server's numerics route back to the client; leveva 402'd → per THE STANDING\nRULE, a bug. **Scope: originating side only** (leveva answering a query forwarded *to* it is a\nfollow-on; in the differential the fake peer plays the answering server).\n- **Outbound:** `hunt::resolve` gained `Hunt::Remote { uplink: Sid }` (glob-match\n `ctx.net.servers()`, own-name wins, mirroring the oracle ISME-first check); `local_query`\n gained `from: &Uid` and on `Remote` forwards the command **verbatim** (UID-prefixed) to the\n uplink peer via `ctx.peers.route`, returning `vec![]` (no synchronous reply).\n- **Inbound back-route:** new `s2s::dispatch` 3-digit-numeric arm → `relay::inbound_numeric`\n resolves the numeric's first param (nick, then literal-UID fallback) and `deliver_uid`s to a\n local client, else routes one hop toward a remote user's uplink, else drops. Point-to-point,\n never split-horizon. Documented prefix divergence (skeleton-invisible): oracle `:nick VERSION\n :peer.test`, leveva `:<uid> VERSION peer.test`.\n- **Differential** (`server_info_forward_skeleton_differential.rs`): a fake peer linked to BOTH\n daemons; full agreement on all 8 verbs (both `hunt_server` target indices — arg0 vs STATS/\n LUSERS arg1) forwarding + reply-back; inverses both-direction: unknown target → 402 + nothing\n forwarded; own-name (oracle `irc.test` / leveva `leveva.test`) → local, nothing forwarded.\n Uses a **LOCAL** `forwarded()` extractor — the shared `verb_skeleton` is a fixed S2S-burst\n allowlist that EXCLUDES query verbs (reusing it yields `[]`; cost time to spot). **Fuzz**\n (`_proptest.rs`, subprocess-per-case): random forwardable verb generalizes; arbitrary peer\n numeric never wedges leveva.\n- **THE STALE-BINARY TRAP (don't re-lose an hour):** the `s2s_support`/`native_oracle_s2s`\n harness runs the leveva **binary** at `target/<profile>/leveva` (located via `current_exe()`'s\n grandparent). `cargo test -p leveva-integration` rebuilds the leveva *lib* but NOT that binary\n → the subprocess silently runs a stale daemon. **Always `cargo build -p leveva --bin leveva`\n before any S2S integration test.** (Symptom: leveva 402'd while a `LINKS` probe proved the\n peer WAS in `ctx.net` — isolating it to the binary, not the logic.)\n\n**Slice 110 ANSWERING SIDE (2026-06-11, same day).** Originally deferred; now closed too. leveva\n**answers** a query a peer forwards to it on behalf of a remote client. New `s2s::query::inbound_query`\n+ s2s::dispatch arms for the 8 verbs: re-run `hunt_server` on `<target>` (us→answer back out the\nlink addressed to the requester / further-remote→forward onward / unknown→402 back). Answers come\nfrom a **shared** `command::query_answer` (+ `query_target_idx`) — the SAME fn the client dispatch\nuses (the 8 client cluster arms collapsed into one arm over it; single source of truth). `command::hunt`\nis now `pub(crate)` for s2s reuse. Differential `server_info_answer_skeleton_differential.rs`: a fake\npeer UNICKs a remote user then asks each daemon; numeric-code skeletons diffed — clean agreement on\nTIME/ADMIN/MOTD/USERS/STATS/LUSERS, VERSION = the documented slice-101 `005`-superset divergence\n(`oracle==leveva[..oracle.len()]`, extras all 005), unknown-target→402 inverse. + a `_proptest.rs`.\n4 new `s2s::query` units. Lib 1170 pass.\n\n**Slice 111 (2026-06-11) — S2S inbound LIVE-RELAY skeleton differential** (the last undiffed S2S\nsurface). `s2s_relay_skeleton_differential.rs` + `_proptest.rs`, reusing `native_oracle_s2s` +\n`s2s_support`, no harness change. A peer bursts a remote **op** `rover` (`@`-prefixed NJOIN, so its\nMODE/KICK are authoritative) into `#peerchan`; a local co-member `obs` + kick-victim `vic` join;\nthe peer then injects `:1ZZZAAAAA PRIVMSG/NOTICE/TOPIC/MODE +m/KICK/PART`. **Characterization — NO\nleveva source change** (its `s2s::dispatch`→`relay::inbound_*`/`s2s::mode` already relays all of\nthem): both daemons relay the identical `[PRIVMSG,NOTICE,TOPIC,MODE,KICK,PART]` verb skeleton to\n`obs`. Uses a **LOCAL `relayed()` extractor** over the CLIENT relay vocabulary (PRIVMSG/NOTICE/\nTOPIC/MODE/KICK/PART/JOIN/QUIT/NICK) — the shared `verb_skeleton` is an S2S-burst allowlist that\nexcludes these (same trap as slice 110's `forwarded()`). Inverses asserted **mid-sequence**: the\nrover-still-present `NAMES` check must run BETWEEN the KICK (removes only `vic`) and the PART\n(removes `rover`) — putting it after PART is a test-ordering bug that fails. Fuzz: random cluster\nverb reaches the co-member (6 cases); arbitrary peer line never wedges leveva (PING→PONG, 10 cases).\nRe-confirmed the slice-110 stale-binary trap. Differential 4 + proptest 2.\n\n**Slice 112 (2026-06-11) — nick-collision fuzzing; the differential matrix is COMPLETE, work\npivots to testing-plan §4 fuzzing gaps.** With slice 111 closing the last undiffed surface, the\nnative cross-daemon skeleton-differential matrix (92–111) is done. §4 lists features with a\ngolden/unit but no proptest; this slice closes `nick_collision`. NOT a differential — leveva's\ncollision policy is the documented *minimal* **first-claimant-wins** (`s2s::unick::handle_unick`:\nthe user already holding a nick keeps it; a later fold-colliding `UNICK` loses, is `SAVE`d to its\nUID + mirrored under it), while the oracle (`save_user`) runs a nick-TS arbitration → the policies\n**diverge**, so a skeleton differential would assert only divergence (§3 anti-pattern). Instead\n`leveva/tests/nick_collision_proptest.rs` pins it against an independent first-claimant model\n(`HashMap<foldkey,Uid>`, same `casemap::fold` the registry keys on): 3 props — model agreement\nover a random `UNICK` sequence (`collision ⇔ a SAVE is emitted`); the freed-slot inverse\n(`handle_save(winner)` frees the nick → a third user takes it cleanly); arbitrary `UNICK`/`SAVE`\nthrough `s2s::dispatch` never panics. +2 inverse units (double-collision keeps the winner;\nfreed nick re-claimable by a different UID). Characterization, no leveva source change. Gate: lib\n1172 (+2), proptest 3/3, golden_nick_collision still green.

Symptoms a real\nclient sees: remote JOIN/PRIVMSG delivered with the **raw UID prefix** (`source_mask` in\n`s2s/relay.rs` can't resolve it) and the user **dropped from remote NAMES**\n(`command::mod::names_reply` does `filter_map(record_of)` — no record ⇒ silently omitted).\n\n**Fix:** `burst::unick_intro(our_sid, rec)` (extracted, shared) + `relay::local_introduce`\nbroadcasting it, called from `finalize_registration` after the record is authoritative.\n**Lesson:** the S2S outbound relays (`local_join/part/nick/quit/...`) must each have a live\n*and* a burst path; the introduction was the one that only had the burst path. `integration_\ntwo_node` masked it by registering everyone *before* the CONNECT — the new\n`integration_post_link_join.rs` registers *after*. See [[leveva-next-step-s2s-completeness]].\n\n**Real-RSS leak audit (the user demanded actual measurement, not slice-85's store\ninspection).** Method: boot real `leveva` daemons, drive load with a Python socket harness,\nsample `/proc/<pid>/VmRSS`. **No unbounded leak found** in: connection churn (flat at\n16764 KB from 11k→30k conns), unique-channel churn (flat, post-run `LIST`=0 → empty channels\nreaped on part), S2S EOF kill/relink (A's RSS plateaus — `squit_subtree` reclaims), and S2S\n**true half-open** (SIGSTOP the peer with a two-node `ping-freq 2` config → remote user\nreaped at t+4s = 2·ping-freq, RSS flat → slice-85 keepalive works on the link path).\n\n**Why the user perceived a \"leak\":** the slice-85 keepalive reaps half-open links but at the\n**default `ping-freq` 90 s** that takes **180 s**; observed for less than ~3 min the remote\nusers persist (working-as-designed-but-slow). The other half was the introduction ghost\nstate above. **Possible future slice:** a dedicated shorter link-health interval independent\nof class `ping-freq`. **Test-harness gotcha:** under `ping-freq 2`, passive Python clients\nthat don't answer `PING` get ping-timed-out in ~4 s — register fast + probe before freezing,\nor they vanish on their own and confound the measurement.\n","numLines":44,"startLine":1,"totalLines":44}},"sourceToolAssistantUUID":"d2036f0e-6861-49c9-8ffa-d542fc7989a2","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 9 9 + {"parentUuid":"03110743-72d0-4a84-9b9f-ec7b0c9705b8","isSidechain":true,"agentId":"ab6c910c34df5e720","message":{"model":"claude-opus-4-8","id":"msg_01LjvLcYqDnfqmAYSbKp6ESp","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_012XA3n9FxAkCYVCcCr9suEo","name":"Read","input":{"file_path":"/home/xe/Code/xeiaso.net/ircd.rs/docs/claude-memory/leveva-prod-shadownet-per-server-probe.md"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":9892,"cache_creation_input_tokens":1038,"cache_read_input_tokens":4613,"cache_creation":{"ephemeral_5m_input_tokens":1038,"ephemeral_1h_input_tokens":0},"output_tokens":5,"service_tier":"standard","inference_geo":"not_available"},"diagnostics":null},"requestId":"req_011CchkJi7d3AJDLDP3rFxU9","attributionAgent":"Explore","type":"assistant","uuid":"b1dbf836-65b6-4dd4-9adb-38a82a5412c8","timestamp":"2026-07-04T21:43:48.254Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"} 10 10 + {"parentUuid":"b1dbf836-65b6-4dd4-9adb-38a82a5412c8","isSidechain":true,"promptId":"ff7d7d06-784b-477e-af53-645dce495494","agentId":"ab6c910c34df5e720","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_012XA3n9FxAkCYVCcCr9suEo","type":"tool_result","content":"1\t---\n2\tname: leveva-prod-shadownet-per-server-probe\n3\tdescription: How to probe the live leveva prod network (ShadowNET) and reach an individual server directly to diagnose cross-server desyncs\n4\tmetadata: \n5\t node_type: memory\n6\t type: reference\n7\t originSessionId: 185addf7-9b58-451e-b56f-a7a37a1de8ed\n8\t---\n9\t\n10\tleveva runs in production as **ShadowNET**.

It closes a latent bug:\nslices 58–66 attached client-only (`@+…`) tags to S2S lines for EVERY peer\nunconditionally → a tag-blind peer mis-parses the leading `@`. leveva now announces\ncaps with a named-token **`CAPAB`** verb as the first burst line, **ENCAP-wrapped**:\n`:<sid> ENCAP * CAPAB :message-tags`. **CRITICAL LESSON (verified):** a *bare*\nunknown server command is FATAL in IRCnet 2.11 — sending `:sid CAPAB …` to the\n`ircd-common` oracle makes it reply `SQUIT`+`ERROR :Closing Link`; `ENCAP` is routed\nto `m_nop` and tolerated, so the link survives. So **any leveva-extension S2S verb\nmust ride ENCAP** (this is why slice 127 re-does REDACT as ENCAP). CAPAB is\n**link-local** (interpreted, never relayed onward). See [[leveva-s2s-peer-caps]] for\nthe full mechanism (`s2s/caps.rs` `PeerCaps`, `PeerLink.caps`, `PeerLinks` egress\ntag-filter, `forward::inbound_encap` CAPAB arm). leveva-native, no oracle differential\nfor the tags; the burst's extra `ENCAP * CAPAB` line is a documented divergence\n`s2s_skeleton_differential` excludes.\n\n**Slice 127 DONE — REDACT → ENCAP (reworked 125's carrier).** Slice 126 proved a *bare*\nunknown server command is FATAL in IRCnet 2.11 (oracle SQUITs), so a first-class\n`:uid REDACT …` is either dropped by a non-implementing peer or kills a strict link.\nleveva now carries it as `:<uid> ENCAP * REDACT <target> <msgid> [:reason]`, exactly like\nCHGHOST/CERTFP/SETNAME. **Delivery semantics unchanged** — `local_redact_channel`\n(broadcast for a channel) + `route_redact_to_remote` (point-to-point to the target's\nuplink) keep the same routing, only the wire builder changed (`encap_redact_wire` egress;\n`client_redact_wire` = the bare client-form line a local cap client receives). `s2s/redact.rs`\n`inbound_redact`→**`apply_encap_redact`** (delivers locally, does NOT relay — the caller\n`forward::inbound_encap` onward-relays the ENCAP verbatim); a `Some(\"REDACT\")` arm added to\n`inbound_encap` next to CHGHOST/CERTFP/SETNAME; the top-level `\"REDACT\"` `s2s::dispatch` arm\nREMOVED (REDACT stays a client command, reached over S2S only via ENCAP; not in the slice-119\nS2S-only reject set so client ports unaffected). Note the ENCAP params are SHIFTED:\n`params() == [\"*\", \"REDACT\", target, msgid, …]` (target at index 2, msgid at 3). Gate =\n`s2s/redact.rs`/`forward.rs` units (`encap_redact_is_applied_and_still_relayed`) +\n`golden_s2s_redact` (snapshot regenerated to the ENCAP egress; alice still sees bare\nclient-form) + `redact_s2s_proptest` with the **new headline P4**\n`outbound_redact_always_rides_encap` (every emitted wire is ENCAP-wrapped — leveva never puts\na bare REDACT server command on the wire). (AWAY 122 + INVITE 123 stay first-class — REAL\nIRCnet verbs the oracle relays.)\n\n**NOTE:** slice 128 went to **outgoing auto-connect** ([[leveva-outgoing-autoconnect]])\nand slice 129 went to **live-join NJOIN propagation** ([[leveva-live-join-njoin]]), so\nmsgid landed as **slice 130** (not 129).\n\n**Slice 130 DONE — msgid S2S propagation.** The IRCv3 message-ids `@msgid` tag was\nsingle-server-local (slice 66 stamped it only for LOCAL recipients). Now it is\nnetwork-stable: the **introducing** server mints one id per message event (the existing\nper-target `msgid_cell`) and carries the SAME id on the S2S wire; a **relaying** server\ncarries the inbound `@msgid` through to its local `message-tags` clients and onward-relays\nverbatim, **NEVER re-minting** (the spec's introducing-server-assigns model — an absent or\nill-formed (`!msgid::is_valid`) inbound id is delivered without one, avoiding two ids for\none event). Mechanism: `relay_wire()` gained a `msgid: Option<&str>` that prepends a\n`msgid` SERVER tag ahead of the client-only (`+`) tags (wire order `@msgid;+client`);\n`local_channel_message`/`route_message_to_remote`/`local_tagmsg`/`route_tagmsg_to_remote`\ntook a `msgid` arg, fed the shared cell by `command/message`+`command/tagmsg` **only when\n`!ctx.peers.is_empty()`**; `inbound_message`/`inbound_tagmsg` read+validate `@msgid` and\ndeliver it to local cap recipients. **Gated on slice 126's CAPAB egress** — the msgid is a\nserver tag, byte-stripped (with the `+` tags) for a tag-blind peer. leveva-native (no\noracle differential). Gate = relay/message/tagmsg units incl. the **per-event network\ninvariant** (local consumer's id == the id on the wire) + inverses (no inbound id ⇒ none\nminted; ill-formed dropped; non-cap member never sees one; egress strips for a tag-blind\npeer) + `golden_s2s_msgid` (both directions, exact id propagated inbound; `canonicalize`\nalready masks `msgid=` → `<MSGID>`) + `msgid_s2s_proptest` (propagate-iff-valid / egress /\npanic-freedom). PREP commit first: fixed pre-existing v0.0.2-bump `LINK_VERSION` (`021-`\nprefix) staleness in one handshake unit + 3 S2S golden snapshots (`cargo test -p leveva`\nwas red on HEAD) — see [[leveva-link-version-021-staleness]].\n\n**Slice 134 DONE — server-time S2S propagation.** The direct `msgid` twin for the\nIRCv3 `@time` tag (slice 62 stamped it only for LOCAL recipients). Now network-stable:\nthe introducing server stamps `@time` on the S2S relay wire (the same `now` it gives\nlocal recipients); `relay::relay_wire` gained a `time: Option<&str>` carried as the FIRST\nserver tag (`@time;msgid;+client`); the four outbound relay fns + `command/message.rs` +\n`command/tagmsg.rs` thread `s2s_time = (!peers.is_empty()).then(|| now.clone())`. Gated on\nslice-126 CAPAB egress (stripped for a tag-blind peer). **Inbound** (`inbound_message`/\n`inbound_tagmsg`) switched from two-precomputed-wires (plain/tagged) to a **per-recipient\n`render(caps)` closure** so `server-time` is gated INDEPENDENTLY of `message-tags`: a\n`server-time` recipient gets the carried `@time` verbatim if well-formed (new\n`clock::is_valid_server_time`), ELSE a synthesized `server_time_now()` fallback (server-time\nis NOT optional for a negotiating client, unlike the optional msgid — this is the one\ndocumented divergence). New fanout helpers `fanout_local_render`/`fanout_local_tagmsg_render`\nreplaced `fanout_local_tagged`/`fanout_local_tagmsg`. leveva-native, no differential. Gate =\nclock/relay units (8 new) + `golden_s2s_server_time` (both dirs) + `server_time_s2s_proptest`\n+ `golden_s2s_msgid` snapshot regen (outbound now `@time=<TS>;msgid=<MSGID>`). The inbound\ntwo-wire→render refactor is the reusable pattern for the remaining bot/oper/account follow-ons.\n\n**Slice 135 DONE — bot/oper inbound-message tags.** The IRCv3 `bot` (slice 64) + `draft/oper`\n(slice 67) tags, stamped only at the LOCAL plane, are now derived on the S2S inbound relay from\nthe remote sender's **mirrored umodes** — `Bot` (`+B`) + `Oper` (`+o`) are both in\n[[leveva-s2s-notify-propagation]]'s `SEND_UMODES`, so they're network-global (`RemoteUser.umodes`,\nseeded by UNICK burst + UMODE propagation). **No carried wire tag, no burst change** — the\nreceiving server re-derives from its own `ctx.net.user()` mirror (the faithful model: these\ntags derive from sender MODES, not assigned per-message like msgid/@time). Hung on slice-134's\nper-recipient `render` seam in BOTH `inbound_message` + `inbound_tagmsg`: read\n`sender_umodes = Uid::try_from(prefix) → ctx.net.user → umodes` once, then in render() stamp\n`draft/oper` iff `sender_is_oper && caps.oper_tag` (independent of message-tags), `bot` iff\n`sender_is_bot && caps.message_tags` (rides message-tags). Order `@time;draft/oper;msgid;bot;+client`.\nRemote oper is always `+o` (`+O`=LocalOp is local-only, never propagates → check `Oper.bit()` only).\nGate = 8 relay units + `golden_s2s_bot_oper` (peer bursts +B bot + +o oper) + `bot_oper_s2s_proptest`\n(the 2×2 derivation gates). leveva-native, no differential.\n\n**Slice 156 DONE — `@account` tag on remote (inbound-relayed) messages.** The last\nS2S-notify follow-on. The `account-tag` `@account` (slice 141, single-server-local) is now\nderived on the S2S inbound `render(caps)` seam in BOTH `inbound_message` + `inbound_tagmsg`,\nexactly the slice-135 bot/oper pattern: read `sender_account = Uid::try_from(prefix) →\nctx.registry.record_of → r.account` ONCE outside the per-target loop (the account SoT is the\nregistry record, populated for remote users via `ENCAP * SU` slice 139 — confirmed\n`record_of` works since UNICK claims remote users into the registry; NO `RemoteUser` mirror\nfield needed), then in render() stamp `account` iff `caps.account_tag && sender_account.is_some()`\n— its OWN cap, independent of message-tags (placed after `draft/oper`, before the message_tags\nblock). Derived, never on the wire, never relayed (each server re-derives from its mirror).\nNew inbound order `time;draft/oper;account;msgid;bot;+client`. Gate = 5 `relay.rs` units +\n`remote_account_tag_proptest` (iff-gate × cap matrix × signed-in?, value fidelity, never-wedge).\nleveva-native, no differential. **The S2S-notify-propagation area is now COMPLETE.**\n\n**Remaining (the area's backlog):** — none. (Was: `@account` remote tag, now done as 156.)\n- ~~`certfp` live post-burst (78)~~ — **ACTUALLY DONE** (this line was stale): slice 86's live\n UNICK introduction (`relay::local_introduce`) reuses `burst::unick_intro`, which already\n appends the `:<uid> ENCAP * CERTFP` line, so a TLS user registering *after* the link is up\n propagates its certfp. No work remained.\n\n**S2S server-source bug (fixed 2026-06-13, commit `ded29694`, NOT a notify-propagation slice):**\na **server**-sourced channel `MODE` (auto-reop from a `+R` reop list, a server `MODE`) prefixes\nthe source server's **SID**. `relay::source_mask` only resolved a *UID* prefix → `nick!user@host`\nand fell through to the raw token otherwise, so `relay::after_mode` delivered the line to local\nclients with the raw SID as the actor (`ServerMode/#chan [+oo a b] by 8OPH`). Fix: `source_mask`\nnow resolves a SID prefix to the server **name** (our own SID → `ctx.name`; a known remote SID →\nits `net.server` mirror name), matching the local `enforce_reop`'s `prefix(&ctx.name)`. The\nonward S2S relay still carries the SID-prefixed wire (correct for the link). **Invariant: any\nserver-sourced line fanned to local clients must translate SID→name via `source_mask`.**\n\n**Pattern for the next one:** clone the `s2s/setname.rs`/`s2s/away.rs` shape —\noutbound `local_*` broadcast + an `inbound_*`/`apply_encap_*` that updates the\nmirror/registry, notifies local cap-havers, and onward-relays; carry state in the\nburst if it isn't already on UNICK. Gate = s2s/command units + a `golden_s2s_*`\nboth-directions boot test + an inbound-lockstep proptest. See\n[[leveva-slice-recording]], [[leveva-next-step-s2s-completeness]].\n\n**Slice 177 DONE — METADATA SET/CLEAR S2S propagation (late addendum, 2026-06-15).**\n`draft/metadata-2` (slices 163/167/169) was the last single-server-local IRCv3\ndivergence: SET/CLEAR mutated the local `MetadataStore` + notified only local\nsubscribers (`command/metadata.rs:38` listed \"S2S propagation … out of scope\").\nNow network-wide via the ENCAP plane, modelled on [[iauth-subsumed-into-leveva]]'s\nneighbour `SU` (slice 139): carrier `:<sid> ENCAP * METADATA <target> <key>\n[:<value>]` (target = **UID** for users so a later GET-by-nick resolves, channel\nname re-folded; value absent = removal; CLEAR → one removal line per key;\nserver-prefixed). New `leveva/src/s2s/metadata.rs`: `propagate` (outbound,\n`broadcast(None,…)`, no-op if no peers) called from `command/metadata.rs`\nset_cmd/clear_cmd after the store mutation; `apply_encap_metadata` wired into\n`forward::inbound_encap` `Some(\"METADATA\")`, gates key_valid + value_valid,\napplies set/remove, reuses `command::metadata::notify_subscribers` (refactored to\n`pub(crate)` + `actor: Option<&Uid>` → `None` for the remote actor). Onward ENCAP\nrelay unchanged (split-horizon → multi-hop converges). Divergences: leveva-native\nno differential; **MAX_KEYS NOT re-enforced inbound** (per-hop cap would desync\nwhich keys exist; origin already enforced); no registration metadata burst (learns\nfrom link time on, like SU's \"no burst re-assertion\"). Fuzzed end-to-end through\n`propagate → inbound_encap` (`leveva/tests/metadata_s2s_proptest.rs`).\n\n**Slices 178-180 DONE — classic-message S2S propagation (2026-06-15, ultracode workflow).**\nThree more single-server-local gaps closed in one parallel-spec → sequential-TDD workflow,\nall modelled on the `s2s/away.rs` shape (local_* outbound broadcast + inbound_* apply/relay):\n- **178 WALLOPS** (`feat 9a2a2ede`). Was local-`+w`-only (\"no S2S yet\"). New `s2s/wallops.rs`:\n `local_wallops` broadcasts `:<oper-uid> WALLOPS :<text>` to peers (called from\n `command/wallops.rs` after the local fan); `inbound_wallops` resolves the source UID→mask\n (registry record else net mirror), fans `:<nick!user@host> WALLOPS :<text>` to LOCAL `+w`\n users only (`is_local_uid` gate — remote `+w` reached by their home server), then onward-relays\n split-horizon. First-class verb (real IRCnet `m_wallops`), not ENCAP. Dispatch arm `\"WALLOPS\"`.\n- **179 KILL** (`feat 6392535e`). Was single-server. New `s2s/kill.rs`: `route_kill_to_remote`\n (a local oper KILLing a *remote* user → routes `:<killer> KILL <victim-uid> :<path>` to the\n victim's uplink via `relay::uplink_of`, does NOT eject locally); `inbound_kill` (a peer's\n `:<src> KILL <victim> :<reason>` → a LOCAL victim is `eject_uid`'d so its serve loop's\n `Session::release` fans the QUIT; a FURTHER-remote victim torn down via\n `squit::quit_one_remote_user`; unknown = no-op-but-relayed; onward split-horizon). Network-kill\n QUIT reason `Killed by <display> (<reason>)` (vs local `Local Kill by …`); killer display via\n `relay::source_mask` (SID→name). First-class verb. Divergences: no `FLAGS_KILLED`/`SCH_KILL`\n server-notice mask (normal QUIT fires); eject is async.\n- **180 metrics** (`feat 747d9765`). `metrics.rs:63` follow-on. Four per-`ServerContext`\n prometheus IntCounters `leveva_s2s_traffic_{sent,recv}_{bytes,messages}_total` incremented in\n `main::serve_linked_peer` read/write sites (pipelined pending-drain skipped to avoid\n double-count); surfaced via two extra `STATS t` `249 :Traffic s2s …` lines. Pure local\n plumbing, no wire change. Two golden snapshots (`golden_metrics`, `golden_stats_traffic`)\n regenerated (the s2s digit self-masks to `s<N>s` under the `:Traffic` canonicalizer).\nAll three: TDD (RED first), a `leveva/tests/*_s2s_proptest.rs` fuzz file each, `cargo build`/\n`clippy`/`test -p leveva` all-green. Verify phase also fixed a stale REDACT doc comment\n(`docs 9d35bf45` — slice 127 already shipped the relay). Final: 2348 tests pass, 0 warnings.\n\n**Slice 182 DONE — SANICK S2S propagation (2026-06-15).** The SA* oper-override family\n(SANICK/SAJOIN/SAPART, slices 151-153) was **local-target only**: a remote target got a `NOTICE`\nciting *\"the KILL-local scope\"* — but slice 179 closed that KILL gap, so the rationale was stale.\nThis continues the 178-180 oper-command arc for the **rename** case. New `leveva/src/s2s/sanick.rs`,\n**server-prefixed ENCAP** (extension verb — slice-126 rule, modelled on SU/METADATA not the\nfirst-class AWAY/WALLOPS/KILL): `propagate` broadcasts `:<our-sid> ENCAP * SANICK <uid> <newnick>`\nto all peers (from `command/sanick.rs` remote branch, replacing the NOTICE); only the target's\n**home server** acts in `apply_encap_sanick` (wired into `forward::inbound_encap` `Some(\"SANICK\")`)\n— runs the SAME local path `try_rename → command::nick::apply_local_nick_change → force_nick_uid`,\nwhose `:<oldmask> NICK <new>` relay then carries the rename network-wide as an ordinary NICK change\n(transit/other servers no-op the ENCAP, update mirror from the NICK). `command/mod.rs` made `mod\nnick` → `pub(crate)` so s2s can reach `apply_local_nick_change`. Network-wide nick collision → `433`\nat the command path (case-only onto target's own nick is NOT a collision); success = no numeric\n(like KILL). Divergences: leveva-native no differential; collision finally resolved at home server\n(race → silent no-op); transparent (looks like a self-rename). Fuzzed via `propagate →\napply_encap_sanick` home-server round-trip proptest. **Follow-on closed in slice 183.** Gate: 1790\nlib + all golden/integration green, clippy clean, workspace 0 warnings.\n\n**Slice 183 DONE — SAJOIN/SAPART S2S propagation (2026-06-15).** The named follow-on to 182;\ncloses the SA* family's last \"local-target only\" deferral. **Structurally simpler than SANICK** —\nno feed-the-line-back-in: the home server's existing `force_join`/`force_part` already relay the\nresulting `:<sid> NJOIN` / `:<uid> PART` to all peers (`join_one` / `s2s::relay::local_part`), so\nthe inbound apply just runs the local force machinery and the network converges from *that* relay\n(every other server no-ops the ENCAP, like SANICK's NICK relay). New `leveva/src/s2s/sajoin.rs` +\n`s2s/sapart.rs`, server-prefixed ENCAP `:<our-sid> ENCAP * SAJOIN <uid> <chans>` /\n`SAPART <uid> <chans> [:reason]`. `propagate` from each command's remote branch (replacing the\nNOTICE; no numeric on success). `apply_encap_sajoin`/`apply_encap_sapart` (wired into\n`forward::inbound_encap` `Some(\"SAJOIN\")`/`Some(\"SAPART\")`): **only the home server acts** (uid\nlocal) — SAJOIN validates each channel name defensively (skip a malformed token, never create a bad\nchannel), SAPART discards the home-side `403`/`442` error (oper is remote). `command/mod.rs` opened\n`mod join`/`mod part` → `pub(crate)` so s2s reaches `force_join`/`registered_view`/`force_part`\n(same pattern 182 used for `nick`). Divergences: remote SAPART gives no `403`/`442` (membership\nlives on home server); single-uplink no-op; transparent (ordinary NJOIN/PART). Fuzzed via\n`propagate → apply` round-trips (joins/parts the local target across an arbitrary channel set).\n**SA* family now S2S-complete** (SAMODE rides ordinary MODE relay). Gate: 2373 tests pass (lib +\nall golden/integration), clippy clean, workspace 0 warnings.\n\n## Slice 188 — services-account netburst re-assertion\n\n`s2s::burst::unick_intro` (shared by the link-time burst + live `relay::local_introduce`) now\nbursts a logged-in user's services account as a following `:<our-sid> ENCAP * SU <uid> :<account>`\nright after the UNICK (after CERTFP/AWAY). Closed the \"burst-re-assertion follow-on\" named in\n`s2s/su.rs`/`s2s/metadata.rs`: a user who logged in via `ENCAP * SU` *before* a link came up\npreviously showed logged-out on a freshly-linked peer (wrong WHOIS `330`/WHOX `%a`/account-notify).\nServer-authoritative → prefix is our SID (matches the live carrier); receiver applies via\n`su::apply_encap_su`. No spurious account-notify (introduced-but-not-yet-NJOIN'd → zero local\nco-members). Live-introduce correct for free (just-registered user has `account == None`).\nMetadata burst re-assertion was the remaining follow-on here — **now closed by slice 189** (below).\n\n## Slice 189 — metadata netburst re-assertion\n\n`s2s::burst::build_burst` now bursts pre-existing `draft/metadata-2` keys: a metadata section after\nthe user/channel sections + before `EOB` emits one `:<our-sid> ENCAP * METADATA <target> <key>\n:<value>` line per stored key, via new `MetadataStore::snapshot` (deterministic, sorted by wire\ntoken) + `MetaTarget::wire_token` (user→UID, channel→folded name). Closes the slice-177 \"No\nregistration metadata burst\" deferral — the metadata analogue of slice 188's account burst.\nServer-authoritative (our SID prefix, matching live `propagate`); the **full** store is bursted\nsince the peer links to us alone. Receiver applies via `apply_encap_metadata` (notifies local\ncapable+subscribed members only). **This was the last named netburst re-assertion follow-on** —\naccount (188) + metadata (189) are both closed. Fuzzed via `metadata_burst_round_trips_an_arbitrary\n_store` (exactly-one-line-per-key + exact store round-trip + empty-store inverse, 3000 cases).\n\n## Slice 280 — RESV/UNRESV S2S propagation (`ENCAP * RESV`/`UNRESV`)\n\nCloses the **S2S `RESV` propagation** follow-on named verbatim in slices 272/273 + `resv.rs`'s\nmodule doc — an operator `RESV`/`UNRESV` was purely single-server. New `s2s/resv.rs` (modelled on\n[[leveva-knock]]/`s2s/metadata.rs`): `propagate_resv`/`propagate_unresv` broadcast `:<our-sid>\nENCAP * RESV <mask> :<reason>` / `:<our-sid> ENCAP * UNRESV <mask>` to every peer (no-op peerless);\n`apply_encap_resv`/`apply_encap_unresv` apply inbound. **Kind is NOT on the wire** — inbound\nre-derives channel-vs-nick from the mask prefix via `resv::is_channel_target` (same as the local\ncommand). `forward.rs` gained `Some(\"RESV\")`/`Some(\"UNRESV\")` arms (applies + onward-relays\nverbatim, split-horizon). `command/resv.rs` calls propagate **after** the param/privilege gates (a\n`461`/`481` propagates nothing; UNRESV propagates unconditionally — network may hold it elsewhere).\nBurst re-assertion `s2s/burst.rs::resv_burst` re-asserts **runtime** (`conf == false`) reservations\nto a freshly-linked peer (after `metadata_burst`, before EOB) via new\n`ResvStore::runtime_entries()`. **Config-vs-runtime boundary:** only operator-laid (`conf == false`)\nreservations propagate; config `resv {}` blocks stay per-server local policy (each server seeds its\nown; inbound-applied lands as `conf == false` so REHASH never drops a network-learned one) —\nmatches charybdis (config RESVs not clustered). Fuzz: 2 in-crate proptests (apply total/consistent\n+ kind-matches-prefix; junk never panics + UNRESV targeted). Remaining slice-272 follow-ons: timed\n`RESV <time>` + reaping an already-present holder.\n\n## Slice 281 — KLINE/UNKLINE S2S propagation (`ENCAP * KLINE`/`UNKLINE`)\n\nThe K-line analogue of slice 280. A `TKLINE`/`UNTKLINE` (leveva's temporary K-line family — there is\nNO separate permanent `KLINE` command) was single-server. New `s2s/kline.rs` (modelled on\n`s2s/resv.rs`): `propagate_kline`/`propagate_unkline` broadcast `:<sid> ENCAP * KLINE <duration>\n<user> <host> :<reason>` / `:<sid> ENCAP * UNKLINE <user> <host>` (no-op peerless);\n`apply_encap_kline`/`apply_encap_unkline` apply inbound. **Duration not absolute expiry on the wire**\n— each server computes `expires = now + duration` against its own clock (no skew); the live command\npropagates the clamped `secs`, `s2s/burst.rs::kline_burst` re-asserts the **remaining** time\n(`expires - now`, active bans only — expired burst nothing), inbound re-clamps `[0, TKLINE_MAXTIME]`.\n`<user> <host>` ride as two params (no `@`-resplit). **Inbound apply reaps LOCAL clients** (network\nban reaps everywhere; a remote user is reaped by its own server) — this fixed a latent over-reap in\nthe local `TKLINE` command by routing both through one `command/tkline.rs::reap_matching` helper now\ncarrying the slice-278 `is_local_uid` guard (+ `kline-exempt` skip). `UNKLINE` does not un-kill\n(lifts the gate only), propagates unconditionally. `TKLINE_MAXTIME` + `now_secs()` promoted to\n`pub`/`pub(crate)` in `kline.rs`. `forward.rs` gained `KLINE`/`UNKLINE` arms. Fuzz: 2 in-crate\nproptests (apply total/consistent; junk never panics + UNKLINE targeted).\n\n## Slice 282 — SQLite persistence for K-lines + reservations\n\n`TKLINE` bans + `RESV` reservations (lost on restart) now persist to the **same `database {}` SQLite\nfile** that backs chat-history ([[leveva-chathistory]]). Each `KlineStore`/`ResvStore` gains\n`db: Option<Mutex<Connection>>` (manual Debug; `new()`/`default()` = in-memory only, every persist\npath a no-op — used by all tests + when no `database {}`): `open(path)` creates a `kline`/`resv` table\n(WAL, `COLLATE NOCASE` PK so a case-differing re-add upserts not duplicates) + **loads** existing rows;\n`add`/`remove`/`prune` write through after the Vec mutation (Vec stays hot-path authority). K-lines\ndrop `expires <= now` rows on load + prune. Resvs persist **only runtime** (`conf == false`) — `add`\npersists, `seed_config` does NOT (config `resv {}` re-derives from `ircd.kdl`; loaded rows land\n`conf == false` so REHASH never drops them); boot order `open` (load runtime) → `seed_config`.\n`server.rs::from_config` opens each store against `cfg.database.path` (log + fall back to `new()` on\nerror).

Identical to `+g` except a\n sender sharing a channel with the target passes without an accept.\n- The block decision is now the pure `callerid::blocks(strict, soft, accepted,\n common_channel)` — the single source of truth + the fuzz target\n (`tests/softcallerid_proptest.rs`). Wrapped by `command::message::caller_id_blocks(ctx,\n target, sender)` (resolves the 4 bools, short-circuits the channel lock), called\n by BOTH the local (`command::message`) and remote-sender (`s2s::relay::inbound_message`)\n gates so they can't disagree. `Channels::shares_channel(a,b)` = the common-channel\n predicate. `+g`/`+G` share the accept store + the 717/718 notify gate; `-g`/`-G`\n clear-notify widened to \"caller-id fully off\".

The C 2.11 oracle has\n14\tno CAP, so this and every IRCv3 slice is leveva-native: **no `leveva-integration`\n15\tdifferential** — the gate is unit + boot-golden + proptest only (like [[leveva-next-step-s2s-completeness]] slices 45–47).\n16\t\n17\t**Hard scope rule (locked with the user):** the negotiation *mechanism* and the *behavior*\n18\tof each capability are **separate slices**.

Behavior-bearing caps — multi-prefix,\n20\tuserhost-in-names, message-tags, server-time, etc. — each get their own later slice and are\n21\tadded to the `SUPPORTED` table in `cap.rs`. Don't fold a behavior cap into a framework change.\n22\t\n23\t**Slice 51 (2026-06-10) shipped `multi-prefix`** — the FIRST behavior-bearing cap. The\n24\treusable pattern for the next behavior cap: add the name const + a `SUPPORTED` entry; add a\n25\tfield to `cap::ClientCaps` (the per-conn snapshot struct) + `CapState::client_caps()`;\n26\t`command::Registered.caps: ClientCaps` holds the snapshot (set at finalize, **re-synced**\n27\tafter `cap.apply` in `session.rs` so a post-registration `CAP REQ` is honored live); the\n28\taffected handlers read `client.caps.<field>`. multi-prefix's effect is\n29\t`MemberStatus::prefixes(multi)` in `channel.rs`, threaded through `names_reply` / WHO\n30\t`who_status` / `whois_channels` (gates NAMES 353 / WHO 352+WHOX 354 / WHOIS 319). Adding a\n31\tcap to `SUPPORTED` changes the LS token list → expect the `golden_cap` snapshots +\n32\t`supported_names` test to update (deliberate). NOTE the churn: `Registered` is built as a\n33\tstruct literal in ~25 test sites — a new field touches all of them (use a `Default` field).\n34\t\n35\t**Slice 53 (2026-06-10) shipped WebSocket transport** (IRCv3 `websocket`) — the first\n36\t**transport** slice (all prior spoke raw TCP/TLS). Served by **axum** (`axum`+`hyper-util`\n37\tdeps; tokio-tungstenite owns the WS protocol) at HTTP path `/socket`. Structure: pure\n38\tIRC-over-WS helpers in `leveva::websocket` (`websocket/mod.rs` — `negotiate`/`decode_incoming`/\n39\t`frame_lines`/`origin_allowed`/`proxy_trusted`, faithful to InspIRCd `m_websocket.cpp`,\n40\tfully proptested) + the axum glue in `leveva::websocket::server` (`websocket/server.rs` —\n41\t`serve_websocket`/`ws_handler`/`serve_ws`). **`tls.rs` was promoted from a binary module to\n42\t`leveva::tls`** so the ws server is a clean lib submodule (it needs `TlsEndpoint`). A\n43\t`listen{}` port becomes a ws port via a nested `websocket{}` block (`origins`/`proxy-ranges`/\n44\t`default-mode`); `Listener.websocket: Option<WebsocketConfig>` + `DefaultMode` in config; the\n45\tbinary's accept loop branches on it. `serve_ws` reuses the **same `Session` state machine**\n46\t(a dedicated `select!`, one ws frame per outbound line via `SinkExt::send`). **New\n47\tleveva-native `UserMode::Websocket` (`+W`, `0x0040`)**: set at registration for ws sessions\n48\t(`Session::set_websocket`), shown in WHOIS as `320`; **propagates network-wide** (in\n49\t`SEND_UMODES` = 125, carried by `UNICK` — the user's explicit call, so remote ws users' WHOIS\n50\tshows 320 too) but **server-set-only** (client `+W` silently ignored). It joins the advertised\n51\tumode list → `RPL_MYINFO`/ISUPPORT are now `oOiwraW` (snapshots updated). Config flag lives in\n52\ta `listen` (NOT `connect`) block.

The reusable pattern for a\n59\tclient-settable leveva-native umode (contrast `+W`'s server-set-only): add the\n60\tvariant to `mode.rs` (`ALL`/`as_char`/`bit`/`from_char`/`from_bit`/`render`/`Display`,\n61\tappended last so oracle bits are untouched); add the letter to the **settable** arm\n62\t`'i' | 'w'` in `command::mode::umode()` AND to `umode_diff`'s iterated list (so the\n63\techo carries it); add the bit to `s2s::umode::SEND_UMODES` to propagate. Surfaced via\n64\t`BOT=B` ISUPPORT (`isupport.rs` — also bumps `user_modes_string()` to `oOiwraWB`, so\n65\tthe 4 `004`/`005` golden snapshots regenerate), `335 RPL_WHOISBOT` in `whois.rs` (after\n66\tthe `320` slot), and the `B` WHO/WHOX flag in `who::who_status` (after `H`/`G` and the\n67\toper `*`). **The `bot` MESSAGE TAG is DEFERRED** to the future `message-tags` slice (user\n68\truling): the `Message` type has no tag rendering yet and the tag only reaches\n69\t`message-tags` subscribers, so it's dormant regardless.

Split framework-vs-behavior per the rule above: **56 = the machinery**, **57 =\n77\tthe delivery behavior**. Slice 56: `Message`/`MessageBuilder` carry ordered\n78\t`tags: Vec<(String,String)>`; `parse` peels a leading `@key=value;...` segment (length-checked\n79\tvs `MAX_TAG_DATA_LEN=8191` → `ParseError::TagsTooLong`, values unescaped via the spec table);\n80\t`write_into` split into `write_tags_into`+`write_body_into` so `to_wire` caps **only the body**\n81\tat 512 and the tag prefix is separate budget; accessors `tags()`/`tag(key)`; builder `.tag(k,v)`.\n82\tEscaping both ways: `;`↔`\\:`, ` `↔`\\s`, `\\`↔`\\\\`, CR↔`\\r`, LF↔`\\n`. Advertised `message-tags`\n83\tin `cap.rs` SUPPORTED + `ClientCaps.message_tags`. **Behavior-bearing on its own**: once\n84\tadvertised, tag-capable clients send `@tag PRIVMSG …` and the server now parses the `@tags`\n85\tsegment correctly (else `@tags` is mistaken for the command); a client-only `+`tag is parsed\n86\tand currently **dropped** (not relayed). **Normalization:** `key` and `key=` both → `(key,\"\")`\n87\t→ render bare `key` (so render→parse→render is a fixed point).

The C 2.11 oracle has\nno CAP, so this and every IRCv3 slice is leveva-native: **no `leveva-integration`\ndifferential** — the gate is unit + boot-golden + proptest only (like [[leveva-next-step-s2s-completeness]] slices 45–47).\n\n**Hard scope rule (locked with the user):** the negotiation *mechanism* and the *behavior*\nof each capability are **separate slices**. Slice 48 shipped the framework + `cap-notify`\nONLY (the one cap the framework itself honors). Behavior-bearing caps — multi-prefix,\nuserhost-in-names, message-tags, server-time, etc. — each get their own later slice and are\nadded to the `SUPPORTED` table in `cap.rs`. Don't fold a behavior cap into a framework change.\n\n**Slice 51 (2026-06-10) shipped `multi-prefix`** — the FIRST behavior-bearing cap. The\nreusable pattern for the next behavior cap: add the name const + a `SUPPORTED` entry; add a\nfield to `cap::ClientCaps` (the per-conn snapshot struct) + `CapState::client_caps()`;\n`command::Registered.caps: ClientCaps` holds the snapshot (set at finalize, **re-synced**\nafter `cap.apply` in `session.rs` so a post-registration `CAP REQ` is honored live); the\naffected handlers read `client.caps.<field>`. multi-prefix's effect is\n`MemberStatus::prefixes(multi)` in `channel.rs`, threaded through `names_reply` / WHO\n`who_status` / `whois_channels` (gates NAMES 353 / WHO 352+WHOX 354 / WHOIS 319). Adding a\ncap to `SUPPORTED` changes the LS token list → expect the `golden_cap` snapshots +\n`supported_names` test to update (deliberate). NOTE the churn: `Registered` is built as a\nstruct literal in ~25 test sites — a new field touches all of them (use a `Default` field).\n\n**Slice 53 (2026-06-10) shipped WebSocket transport** (IRCv3 `websocket`) — the first\n**transport** slice (all prior spoke raw TCP/TLS). Served by **axum** (`axum`+`hyper-util`\ndeps; tokio-tungstenite owns the WS protocol) at HTTP path `/socket`. Structure: pure\nIRC-over-WS helpers in `leveva::websocket` (`websocket/mod.rs` — `negotiate`/`decode_incoming`/\n`frame_lines`/`origin_allowed`/`proxy_trusted`, faithful to InspIRCd `m_websocket.cpp`,\nfully proptested) + the axum glue in `leveva::websocket::server` (`websocket/server.rs` —\n`serve_websocket`/`ws_handler`/`serve_ws`). **`tls.rs` was promoted from a binary module to\n`leveva::tls`** so the ws server is a clean lib submodule (it needs `TlsEndpoint`). A\n`listen{}` port becomes a ws port via a nested `websocket{}` block (`origins`/`proxy-ranges`/\n`default-mode`); `Listener.websocket: Option<WebsocketConfig>` + `DefaultMode` in config; the\nbinary's accept loop branches on it. `serve_ws` reuses the **same `Session` state machine**\n(a dedicated `select!`, one ws frame per outbound line via `SinkExt::send`). **New\nleveva-native `UserMode::Websocket` (`+W`, `0x0040`)**: set at registration for ws sessions\n(`Session::set_websocket`), shown in WHOIS as `320`; **propagates network-wide** (in\n`SEND_UMODES` = 125, carried by `UNICK` — the user's explicit call, so remote ws users' WHOIS\nshows 320 too) but **server-set-only** (client `+W` silently ignored). It joins the advertised\numode list → `RPL_MYINFO`/ISUPPORT are now `oOiwraW` (snapshots updated). Config flag lives in\na `listen` (NOT `connect`) block. End-to-end gate: a real `tokio-tungstenite` client in\n`tests/golden_websocket.rs`. leveva-native (no differential). Also added the table-formatted\n`HELP USER_MODES`/`CHANNEL_MODES` topic pages (see [[help-files-per-command]]). Plan:\n`docs/superpowers/plans/2026-06-10-p11-slice53-websocket.md`.\n\n**Slice 55 (2026-06-10) shipped IRCv3 bot mode** — a *client-settable* `+B` umode\n(`UserMode::Bot`, bit `0x0080`, leveva-native). The reusable pattern for a\nclient-settable leveva-native umode (contrast `+W`'s server-set-only): add the\nvariant to `mode.rs` (`ALL`/`as_char`/`bit`/`from_char`/`from_bit`/`render`/`Display`,\nappended last so oracle bits are untouched); add the letter to the **settable** arm\n`'i' | 'w'` in `command::mode::umode()` AND to `umode_diff`'s iterated list (so the\necho carries it); add the bit to `s2s::umode::SEND_UMODES` to propagate. Surfaced via\n`BOT=B` ISUPPORT (`isupport.rs` — also bumps `user_modes_string()` to `oOiwraWB`, so\nthe 4 `004`/`005` golden snapshots regenerate), `335 RPL_WHOISBOT` in `whois.rs` (after\nthe `320` slot), and the `B` WHO/WHOX flag in `who::who_status` (after `H`/`G` and the\noper `*`). **The `bot` MESSAGE TAG is DEFERRED** to the future `message-tags` slice (user\nruling): the `Message` type has no tag rendering yet and the tag only reaches\n`message-tags` subscribers, so it's dormant regardless. Tests: dedicated\n`bot_mode_proptest.rs` (lockstep `{i,w,B}` model + observer WHO/WHOIS) + `golden_bot_mode.rs`.\nPlan: `docs/superpowers/plans/2026-06-10-p11-slice55-bot-mode.md`.\n\n**Slice 56 (2026-06-10) shipped the `message-tags` FOUNDATION** — the highest-leverage\nIRCv3 slice, because the `Message` type had **no** tag support, the hard prerequisite\nblocking ≥5 spec'd caps (the slice-55 bot tag, server-time, message-ids, message-redaction,\noper-tag). Split framework-vs-behavior per the rule above: **56 = the machinery**, **57 =\nthe delivery behavior**. Slice 56: `Message`/`MessageBuilder` carry ordered\n`tags: Vec<(String,String)>`; `parse` peels a leading `@key=value;...` segment (length-checked\nvs `MAX_TAG_DATA_LEN=8191` → `ParseError::TagsTooLong`, values unescaped via the spec table);\n`write_into` split into `write_tags_into`+`write_body_into` so `to_wire` caps **only the body**\nat 512 and the tag prefix is separate budget; accessors `tags()`/`tag(key)`; builder `.tag(k,v)`.\nEscaping both ways: `;`↔`\\:`, ` `↔`\\s`, `\\`↔`\\\\`, CR↔`\\r`, LF↔`\\n`. Advertised `message-tags`\nin `cap.rs` SUPPORTED + `ClientCaps.message_tags`. **Behavior-bearing on its own**: once\nadvertised, tag-capable clients send `@tag PRIVMSG …` and the server now parses the `@tags`\nsegment correctly (else `@tags` is mistaken for the command); a client-only `+`tag is parsed\nand currently **dropped** (not relayed). **Normalization:** `key` and `key=` both → `(key,\"\")`\n→ render bare `key` (so render→parse→render is a fixed point). Tests: message.rs units +\n`message_tags_proptest.rs` (round-trip/escaping/never-panic/untagged-no-regression) + the 2\n`golden_cap` snapshots regenerated. **Slice 57 (NEXT, deferred) = the behavior:** the `TAGMSG`\ncommand, client-only (`+`) tag relay to `message-tags` subscribers (per-recipient cap gating\nin the delivery plane — `command/message.rs` currently sends ONE wire to all members, so this\nneeds a tagged/untagged split keyed on each recipient's `ClientCaps.message_tags` — AND across\nS2S `relay.rs`), and `417 ERR_INPUTTOOLONG` on oversized inbound tag data. Plan:\n`docs/superpowers/plans/2026-06-10-p11-slice56-message-tags.md`. Once it lands, attaching a tag\nis just `Message::builder(..).tag(\"time\", ts)` — server-time/msgid/bot-tag/oper-tag become thin\nfollow-ons.\n\n**Slice 58 (2026-06-10) shipped the message-tags DELIVERY PLANE** — the behavior slice 56\ndeferred (it landed as **58**, not 57; slice 57 took the PRIVMSG mask-targets path instead).\nThree pieces: (1) `TAGMSG <target>` (new `command/tagmsg.rs` + dispatch arm + `s2s::relay::\ninbound_tagmsg`/`local_tagmsg`/`route_tagmsg_to_remote`), delivered **only** to `message-tags`\nconsumers (a non-consumer gets nothing; for a nick target not an error); errors mirror PRIVMSG\n(411/404/401, no 412); (2) per-recipient **client-only (`+`) tag relay** on PRIVMSG/NOTICE/\nTAGMSG — `Message::client_only_tags()` (new) filters the `+`-prefixed subset; the fan-out\nbuilds a tagged variant for cap-havers and the plain wire for everyone else; unprefixed server\ntags stripped; carried across S2S unconditionally (`local_channel_message`/`route_message_to_\nremote` gained a `tags` param). The gate is a **`ClientRecord.caps: ClientCaps` snapshot**\nmirrored from the connection via new `Registry::set_caps`/`caps_of` (at registration + post-reg\n`CAP`), exactly as `set_modes` mirrors `+i`; (3) `417 ErrInputtoolong` (new numeric) in\n`session.rs::feed` on `ParseError::TagsTooLong` (no longer a silent drop; pre-reg target `*`).\nDivergences: mask broadcasts don't carry client tags; a `$$`/`$#` TAGMSG target isn't a mask\n(→401); no `CLIENTTAGDENY`. Help: `help/TAGMSG.md` + index. Tests: units across message/tagmsg/\nregistry/session/relay + `golden_tagmsg.rs` + `tagmsg_proptest.rs` (the full assembled CAP→reg→\ndelivery gate). See [[leveva-message-tags-seams]]. Plan: `docs/superpowers/plans/2026-06-10-\np11-slice58-tagmsg-client-tags-417.md`. Now attaching a tag is just `.tag(\"time\", ts)` →\nserver-time/msgid/bot-tag/oper-tag are thin follow-ons.\n\n**Behavior caps on the slice-58 cap mirror (59–61, 2026-06-10):** once the\n`Registry::set_caps`/`caps_of` + `Registered.caps` snapshot existed, each subsequent\nbehavior cap is a thin per-recipient/per-sender gate read off it — no new plumbing. **59\n`away-notify`** (`:nick AWAY [:msg]` to a channel co-member's negotiating clients on an away\n*change* or away-user JOIN; gate `caps_of(recipient).away_notify`). **60 `invite-notify`**\n(`:inviter INVITE <target> :<chan>` to channel **ops** that negotiated it on a successful\nINVITE; `command/invite.rs::notify_channel_ops`). **61 `echo-message`** (sender gets a copy\nof its own PRIVMSG/NOTICE/TAGMSG per successful target; `command/message.rs` + `tagmsg.rs`\n`echo_to_sender` closure reusing the slice-58 `pick` so the echo carries `+` tags iff the\nsender consumes message-tags; gate is **`client.caps.echo_message` straight off the\n`Registered`** — no `caps_of` round-trip, the sender is the local connection). Common\ndivergence shared by 59/60: **remote** members aren't notified (single-server local-mailbox\nrelay). echo-message was deliberately chosen over `server-time` for slice 61 to keep golden\nsnapshots wall-clock-deterministic. Plans: `…slice59-away-notify.md`/`…slice60-invite-notify.md`/`…slice61-echo-message.md`.\n\n**Slice 62 (2026-06-10) shipped `server-time`** — the server stamps an\n`@time=YYYY-MM-DDThh:mm:ss.sssZ` (RFC 3339 millis, UTC) tag on each delivered/echoed\n`PRIVMSG`/`NOTICE`/`TAGMSG` for a negotiating recipient. Reusable patterns established: (1)\nthe per-target `pick(bool)` in `command/message.rs`/`tagmsg.rs` became `render(ClientCaps)` —\nchoose the plain-vs-`+`tagged base by `caps.message_tags`, then `Message::with_server_time(&now)`\niff `caps.server_time` (the helper prepends a `(\"time\",ts)` tag at the FRONT so it renders\nbefore client `+`tags); fan-out renders with `caps_of(recipient)`, the slice-61 echo with the\nsender's own `client.caps`. (2) **No `ServerContext` clock field** — that would break ~40\n`ServerContext {…}` test literals; instead the timestamp is a pure free fn\n`clock::format_rfc3339_millis(u64)` (Howard-Hinnant civil_from_days; total/panic-free;\nfixed-width + lexicographically monotonic since the year is always 4 digits → the prime\nfuzz/proptest target) and golden determinism comes from a **canonicalizer `time=<TS>` mask**\n(the established RPL_CREATED/333/391 pattern) + presence/shape (not pinned-value) assertions in\nunit/proptest. Scope = the message delivery plane ONLY (the slices-56/58/61 surface); JOIN/PART/\nQUIT/MODE/TOPIC/etc., numeric replies, mask broadcasts, and **remote** members are deliberate\nfollow-ons (each thin now `with_server_time` exists). `SERVER_TIME` appended to `SUPPORTED` +\n`ClientCaps.server_time` (so the six LS-string asserts + `supported_names` + 2 `golden_cap`\nsnapshots regenerate). **`server-time` was deferred from slice 61 for snapshot determinism —\nnow solved by the canonicalizer mask, so future wall-clock-volatile caps golden-test the same\nway.** Plan: `docs/superpowers/plans/2026-06-10-p11-slice62-server-time.md`.\n\n**Slice 63 (2026-06-10) shipped `userhost-in-names`** — a new cap (`UHNAMES` in `SUPPORTED` +\n`ClientCaps.userhost_in_names`) that renders every `353 RPL_NAMREPLY` member as\n`nick!user@host` instead of the bare nick, gated by the **requester's own** cap (read off\n`client.caps`, no `caps_of`). One renderer change: `command/mod.rs::names_reply` gained a\n`userhost_in_names: bool` param, resolves each member via `Registry::record_of` (nick+user+host)\nand composes with `multi-prefix` sigils (`@+nick!user@host`); the 3 call sites (NAMES named/sweep\n+ JOIN burst) thread `client.caps.userhost_in_names`. The legacy `PROTOCTL UHNAMES`/ISUPPORT\nmethod is deliberately NOT implemented (CAP-only, per the RFC). Plan:\n`…slice63-userhost-in-names.md`.\n\n**Slice 64 (2026-06-10) shipped the `bot` MESSAGE TAG** — lit up slice 55's deferred bot tag,\nthe thin follow-on mirroring slice 62. **Key contrast with 59–63: NO new capability.** The bot\ntag isn't negotiated by the receiver — it's gated by the **existing** `message-tags` cap AND the\n**sender's** `+B` mode (`sender_is_bot = client.modes & UserMode::Bot.bit() != 0`), so\n`cap.rs`/`ClientCaps`/`SUPPORTED` are untouched. New `Message::with_bot_tag()` inserts a valueless\n`(\"bot\",\"\")` at the FRONT (like `with_server_time`; both → `@time;bot;+client`). The\n`render(caps)` closures in `command/message.rs`/`tagmsg.rs` became a 2×2 match over\n`(bot, server_time)` where `bot = sender_is_bot && caps.message_tags`; the echo carries `@bot` iff\nthe bot sender itself consumes message-tags. Scope = PRIVMSG/NOTICE/TAGMSG delivery plane only\n(other commands + numerics + remote members are follow-ons — a remote's own server stamps the tag\nfrom network-propagated `+B`). Gate: units + `golden_bot_tag.rs` + `bot_tag_proptest.rs` (the\nvalueless tag is deterministic → no canonicalizer rule). Plan: `…slice64-bot-tag.md`.\n\n**Slice 66 (2026-06-10) shipped `message-ids` (the `msgid` tag)** — the next thin follow-on\nafter 62/64. **NO new capability** (rides `message-tags`, like the slice-64 bot tag, so\n`cap.rs`/`ClientCaps`/`SUPPORTED` untouched). New `leveva::msgid` module:\n`generate(sid)`=`<sid>-<hex AtomicU64 counter>` (monotonic→unique, sid prefix→cross-server\nunique) + `is_valid(s)` (spec byte rule: non-empty, no leading `:`, no SPACE/CR/LF). New\n`Message::with_msgid(id)` prepends `(\"msgid\",id)` between `with_bot_tag` and `with_server_time`\n→ wire order `@time;msgid;bot;+client`. The `render(caps)` closures in `command/message.rs`/\n`tagmsg.rs` went from a 2×2 `(bot,server_time)` match to a small composition (fast path +\nconditional `with_bot_tag`/`with_msgid`/`with_server_time`). **Per-event invariant:** one id per\ntarget, minted lazily into a per-target `std::cell::OnceCell<String>` so every channel member +\nthe echo of one message share the SAME id; distinct messages differ. Gated on `message-tags`\n(spec) → a server-time-only consumer gets `@time` but no `msgid` (verified: server-time/echo/\nprivmsg goldens unchanged). Canonicalizer gained a `msgid=<MSGID>` mask (counter-derived →\nvolatile, like `time=<TS>`); `golden_bot_tag`/`golden_tagmsg` snaps regenerated to `@msgid=…;bot`\n/`@msgid=…;+example=…`. Divergences: single-server-local (S2S relay unchanged, remote stamps its\nown); in-memory counter resets on restart (spec calls this out, accepted). Gate: `msgid.rs`/\nmessage/tagmsg units + `golden_msgid.rs` + `msgid_proptest.rs` (400 cases: gated-iff-cap,\nalways-valid, per-event sharing + distinctness, panic-freedom). Plan: `…slice66-msgid.md`.\n\n**Slice 67 (2026-06-10) shipped `oper-tag` (the `draft/oper` tag)** — the next IRCv3 cap after 66.\n**HAS its own capability `draft/oper-tag`** (unlike the bot/msgid tags that ride `message-tags`),\nso `cap.rs`/`ClientCaps.oper_tag`/`SUPPORTED` DO gain an entry (the 8 LS-string asserts +\n`supported_names` + 2 `golden_cap` snaps regenerate, appending ` draft/oper-tag`). Mechanism =\nthe slice-64 bot-tag analog with two swaps: gate bit is `+o`/`+O` (`sender_is_oper`, hoisted next\nto `sender_is_bot`, reused for the existing `$$`/`$#` mask check) not `+B`, and the recipient gate\nis `draft/oper-tag`'s OWN cap (independent of `message-tags`, per spec — negotiating the cap\ndeclares the client parses tags). New `Message::with_oper_tag()` prepends a **valueless**\n`(\"draft/oper\",\"\")` (`draft/` prefix MANDATORY until the WIP spec ratifies — both cap name\n`draft/oper-tag` and tag name `draft/oper`); applied after `with_msgid`, before `with_server_time`\n→ wire `@time;draft/oper;msgid;bot;+client`. The `render(caps)` closures in\n`command/message.rs`/`tagmsg.rs` add `oper_tagged = sender_is_oper && caps.oper_tag` to the no-tag\nfast-path guard + a `with_oper_tag()` arm. **Divergence: VALUELESS tag** (spec permits valued\n`draft/oper=<account>` but leveva keeps no post-OPER account store — only the mode bit + privilege\nset; valueless conveys the security-relevant fact, the spec's own example line 2). Scope =\nPRIVMSG/NOTICE/TAGMSG delivery plane only; single-server-local (S2S unchanged); no mask-broadcast\ntagging. Gate: cap/message/tagmsg units + `golden_oper_tag.rs` (alice `OPER root hunter2` then\nspeaks; dan w/ `draft/oper-tag` sees `@draft/oper`, mel bare) + `oper_tag_proptest.rs` (400 cases,\nfull 2×2 truth table sender-oper×recipient-cap + toggle-flips-tag inverse + panic-freedom). Plan:\n`…slice67-oper-tag.md`. **Pitfall: a blanket `perl -pe` over `userhost-in-names\\r\\n` also hits the\n`CAP REQ :userhost-in-names` ACK assertions — patch the LS line only.**\n\n**Slice 68 (2026-06-10) shipped `message-redaction` (the `REDACT` command + `draft/message-redaction`\ncap)** — the next IRCv3 cap after 67, and **TWO firsts on the track: the first NEW COMMAND\n(`REDACT`) and the first standard-replies `FAIL` line.** Cap added to `cap.rs`/`SUPPORTED`/\n`ClientCaps.message_redaction` (LS-string asserts + `supported_names` + 2 `golden_cap` snaps\nregenerate, appending ` draft/message-redaction`). New `command/redact.rs` +\n`mod redact;`/dispatch arm `\"REDACT\"`: `REDACT <target> <msgid> [<reason>]` routes like a PRIVMSG\nto a **single** target (no comma list, per the spec's singular `<target>`) and forwards\n`:sender!u@h REDACT <target> <msgid> [:reason]` only to recipients with `message_redaction`\n(others get NOTHING, spec MUST NOT). **Key design = STATELESS RELAY:** leveva keeps no message\nhistory (msgids are an in-memory counter, slice 66), so it does NO authorship/permission/\nmsgid-existence validation and NEVER emits `UNKNOWN_MSGID`/`REDACT_FORBIDDEN`/\n`REDACT_WINDOW_EXPIRED` — the spec's explicit relay model. The one reachable error is the spec's\n`FAIL REDACT INVALID_TARGET <target> :You cannot delete messages from <target>` (leveva's FIRST\n`FAIL`; the full standard-replies framework — the `standard-replies` cap, WARN/NOTE — is a later\nindependent-track slice). Reason read from `msg.trailing()` OR `params()[2]` (single-word reason\ncan be a plain middle param), always re-emitted as trailing. Divergences: sender cap NOT enforced\n(any registered client may send REDACT; gate is recipient-only — the TAGMSG precedent);\nsingle-server-local (S2S relay of REDACT deferred); no server tags on the REDACT line;\n`message-tags` dependency not enforced (caps ACKed independently). Gate: cap unit + 10 redact\nunits (incl. inverses: non-cap co-member/nick gets nothing, sender skipped, moderated/ghost →\nFAIL, absent-reason → no trailing) + `golden_redact.rs` (bob w/ cap sees REDACT, mel plain sees\nnone — sentinel-PRIVMSG technique) + `redact_proptest.rs` (400 cases: delivered-iff-cap,\nreason-preserved, toggle-flips-delivery, panic-freedom). Plan:\n`…slice68-message-redaction.md`. **Pitfall: `Message::params()` EXCLUDES the trailing param —\nassert the reason via `m.trailing()`, not `params()[2]`.**\n\n**Slice 69 (2026-06-10) shipped `standard-replies` (the `FAIL`/`WARN`/`NOTE` framework + cap)** —\na **framework slice** (the framework-vs-behavior split, like slice 48/56): it formalized the\nslice-68 ad-hoc redact `FAIL` into a shared builder + advertised the cap. New `leveva::stdreply`\nmodule: `ReplyType{Fail,Warn,Note}` (`verb()`) + `standard_reply(server, ty, command, code,\ncontext: &[&str], description) -> Message` + `fail`/`warn`/`note` wrappers (format `<TYPE>\n<command> <code> [<context>...] :<description>`; prefix=server, description always trailing).\n`cap.rs` gained `STANDARD_REPLIES=\"standard-replies\"` + SUPPORTED (appended LAST) +\n`ClientCaps.standard_replies` + client_caps line (→ the 8 LS-string asserts + `supported_names` +\n2 `golden_cap` snaps regenerate, appending ` standard-replies`; the slice-68 message_redaction\n\"advertised last\" assert relaxed to containment). `command/redact.rs::fail_invalid_target`\nrefactored onto `stdreply::fail` — **byte-identical**, so slice-68 redact units/golden/proptest\nunchanged. **KEY divergence (= teeth deferred, like message-tags slice 56):** the cap is\nadvertised/negotiable + the builder is live, but `ClientCaps.standard_replies` is **wired but not\nyet read** — a `FAIL` enabled by a specific spec (the redact one) is sent regardless of the cap;\nthe cap governs only ARBITRARY (non-spec-enabled) replies, which leveva doesn't emit yet. No\nWARN/NOTE caller yet. Gate: 6 stdreply units + the cap unit + `golden_standard_replies.rs` (negotiate\ncap, `REDACT #nope 123`→`FAIL REDACT INVALID_TARGET #nope`) + `stdreply_proptest.rs` (400 cases,\nthe fuzz target = the new builder: build→to_wire→parse round-trip + empty-context-no-stray-param +\npanic-freedom). **Fuzz finding:** a middle param (command/code/context) must NOT start with `:`\n(re-parses as the trailing) — constrained the generator's first char (real codes are uppercase\nidents). Plan: `…slice69-standard-replies.md`.\n\n**Slice 70 (2026-06-10) shipped `MONITOR`** — the IRCv3 online/offline watch list, and the\ntrack's FIRST **server-pushed-on-a-lifecycle-event** feature (vs gating a reply). **NOT a CAP**\n— advertised via the `MONITOR=100` ISUPPORT (005) token, so `cap.rs`/`SUPPORTED` untouched (but\nthe 005 list hit 14 tokens → `NETWORK` wraps to a 2nd 005 line, `TOKENS_PER_LINE=13`; 5\n005-goldens regenerated). New `leveva::monitor` module: `MONITOR_LIMIT=100` + a shared\n`Monitors` index (`Mutex<{by_target: folded-nick→HashSet<watcher Uid>, by_watcher:\nUid→Vec<display>}>`) — **watch state keyed by the watcher's UID, NOT on `Registered`** (the key\ndesign choice: avoids the ~25 Registered test-literal sites — the slice-51 churn lesson) — plus\nfree fns `notify_online`/`notify_offline` (deliver `730 :nick!u@h` / `731 :nick` to each\nwatcher's mailbox, addressed to the watcher's live nick). New `command/monitor.rs` + dispatch\narm: `+`(add≤limit, report 730/731, overflow→`734`)/`-`/`C`/`L`(732+733)/`S`, comma-chunked\nwithin the 512 budget; no-modifier→461, unknown modifier/invalid-nick→silent skip. Live-notify\nhooks at the lifecycle seams: `session.rs::finalize_registration`→online, `session.rs::release`→\noffline + `monitors.clear`, `command/nick.rs::nick_change`→offline(old)+online(new) (a rename =\noffline-of-old + online-of-new). Numerics 730–734 added. `ServerContext.monitors` field (+ the\n43 proptest literals, inserted after `peers:`). Help: `help/MONITOR.md` + COMMANDS + index.\n**KEY divergence: single-server-local** — online status (`+`/`S`) reads the registry (which holds\nremote S2S users), but live `730`/`731` pushes fire only on LOCAL events; remote transitions over\nS2S don't push (the track's single-server stance, slices 59+). Other divergences: CAP-less (no\nPROTOCTL/WATCH); 730 always carries the hostmask; re-add is a silent no-op. Gate: monitor module\nunits (6) + command units (11) + live-notify seam units (session/nick) + `golden_monitor.rs`\n(two clients: offline→online→offline) + `monitor_proptest.rs` (3: index-vs-model, chunker\nbudget/lossless/capped, junk-never-panics). Plan: `…slice70-monitor.md`.\n\n**Slice 71 (2026-06-10) shipped `chghost`** — the operator self-`CHGHOST` command + the cap notify\nplane + `ENCAP CHGHOST` S2S relay (the user explicitly directed: \"to get chghost working you need\nto send encap CHGHOST commands to other links\"). `chghost` added to `cap.rs`/`SUPPORTED`/\n`ClientCaps.chghost` (LS-string asserts + `supported_names` + 2 `golden_cap` snaps regenerate,\nappending ` chghost`). **Origination is SELF-only** (`CHGHOST <newuser> <newhost>` changes the\n*issuing* oper's own identity — it owns its `Registered`, so the mutation is in-place and correct;\ntargeting another user needs a control-envelope leveva lacks, a documented future extension — this\nis what resolves the old \"needs a vhost path\" blocker). Gated on `+o`/`+O` like KILL (**no new\n`OperPrivilege`** — that enum is 1:1 with oracle `ACL_*` bits); new `Registry::set_host` mirrors\nuser+host. **The shared `s2s::chghost::notify_co_members(ctx,uid,nick,old_user,old_host,newuser,\nnewhost)` does the spec's TWO delivery modes per local co-member:** a `chghost` consumer gets\n`:nick!old_user@old_host CHGHOST <newuser> <newhost>`; a **non-cap** member gets the\nreconnect-simulation fallback `QUIT :Changing host` → per-shared-channel `JOIN` (new mask) +\nserver `MODE <chan> +<o/v> <nick>` (new `Channels::member_status`) — the user mid-slice required\nthe fallback (it was first deferred). Self-echo (cap only) is the handler return (co_members\nexcludes self). **S2S carrier = `ENCAP`:** `local_chghost` broadcasts `:<uid> ENCAP * CHGHOST u h`\nto all peers; `forward::inbound_encap` routes the `CHGHOST` subcommand to `s2s::chghost::\napply_encap_chghost` (updates the `RemoteUser` mirror + registry + notifies local co-members; the\nchanged user = the message source uid, like `UMODE`) while still onward-relaying every ENCAP\nverbatim (a non-CHGHOST ENCAP stays opaque — slice-35 regression guarded). **Fuzz finding:** a\nleading-`:` user/host passes the typed `UserName`/`HostName` validators (idents/IPv6 admit `:`)\nbut can't be an IRC middle param (reparses as trailing) → the handler rejects it with a NOTICE\n(defensive — the wire parser never yields such a param; the proptest builds messages directly).\nInvalid input → NOTICE (no standard-replies code, avoids the slice-69 gate). Gate: cap/registry/\ncommand(10)/s2s(6)/forward(2) units + `golden_chghost.rs` (oper+cap alice, cap bob, plain mel: bob\n& self get CHGHOST, mel gets QUIT/JOIN/MODE) + `chghost_proptest.rs` (the fuzz target: command\nvalid-applies/invalid-inert + last-valid model; inbound tracks-last-valid + never-panics; non-CHGHOST\nENCAP inert). Plan: `…slice71-chghost.md`.\n\n**Slice 76 (2026-06-10) shipped `utf8only`** — the `UTF8ONLY` ISUPPORT token (NOT a cap;\n`isupport.rs::tokens`, before `NETWORK`) + the `INVALID_UTF8` standard reply. Before this slice\n`session.rs::feed` lossy-decoded every inbound line (`from_utf8_lossy`), silently mangling\nnon-UTF-8 into U+FFFD and dispatching it. Now `feed` gates on `std::str::from_utf8(&line)`:\n`Err` → `stdreply::fail(name, command, \"INVALID_UTF8\", &[], INVALID_UTF8_DESC)` + `continue` (no\ndispatch); `command` = the ASCII-validated verb from a lossy parse (`*` otherwise). Sent\n**unconditionally** (enabled-by-spec, like the redact FAIL — not gated on `standard-replies`).\nWhole-line rejection (not content-only); no WARN/modify variant. Outbound truncation was already\nchar-boundary safe (`to_wire`). Additive harness `Client::send_raw(&[u8])`. **Interaction found:\nthe `ping_arbitrary_bytes_are_robust` proptest** asserted any non-framing token PONGs (the old\nlossy contract) → split to PONG-iff-valid-UTF-8, INVALID_UTF8-otherwise (separate `test(leveva)`\ncommit). Regenerated the 4 full-burst 005 snapshots (UTF8ONLY joins the 2nd 005 line;\n`golden_bot_mode` snapshots only the 1st line → untouched). Gate: isupport/session units +\n`golden_utf8only` + `utf8only_proptest`. Plan: `…slice76-utf8only.md`.\n\n**Slice 155 (2026-06-14) shipped `labeled-response` (+ the `batch` framing dependency)** — the\nserver echoes a command's inbound `@label` tag back on its **direct reply** so a client can\ncorrelate request→reply. **Seam:** `session::Session::dispatch`'s registered arm already had the\nsynchronous replies as `command::dispatch() -> Vec<Message>`; that vector now feeds the pure\n`leveva::labeled::wrap(enabled, label, server, batch_ref, replies)` before write — non-negotiating/\nunlabeled commands pass through verbatim (common path). **Three shapes** (real ircv3.net spec, now\nin `docs/rfcs/ircv3/labeled-response.md`): 0 replies → `@label :<srv> ACK`; 1 → that message gets\n`@label` prepended in place; ≥2 → a `labeled-response` batch (`@label :<srv> BATCH +<ref>\nlabeled-response` / inners `@batch=<ref>` / `:<srv> BATCH -<ref>`). `batch_ref` = `labeled::next_ref()`\nover a process-global `AtomicU64` (the `msgid::COUNTER` precedent), generated by the caller so\n`wrap` stays a pure fuzz target. New `Message::with_label`/`with_batch` (the `with_server_time`\nfront-prepend pattern). **Advertised BOTH `labeled-response` + `batch`** in `cap.rs` SUPPORTED\n(batch = the wire dependency; `ClientCaps` gained both fields; the wrap **gate is `labeled_response`\nonly** — `batch` is wired-but-not-read, the slice-69 `standard_replies` pattern; a future dedicated\nbatch slice adds OTHER batch *types* netjoin/netsplit/chathistory). **Key divergence: direct-reply\npath ONLY** — async mailbox lines (`echo-message`, channel fan-out) travel `registry::deliver_uid`\nand are NOT in a labeled batch (a labeled `PRIVMSG`→`ACK`, echo arrives separately untagged — which\n*satisfies* the spec's self-message MUST-NOT-label rule conservatively); commands intercepted before\nthe seam (`QUIT`/`CAP`/pre-reg `AWAY`) aren't labeled; label echoed verbatim trusting the ≤64-byte\nclient contract. leveva-native (no differential — oracle predates CAP). The spec's `PONG → ACK` and\n`WHOIS`-batch examples both work as-is (PONG returns `Vec::new()` from `command::dispatch`). **Pitfall\nthat cost time: I first hallucinated the spec doc — the user had the REAL one and replaced it; the\nimplementation was already correct against it.** Gate: labeled/message/cap units + `labeled_response_proptest`\n(600 cases over pure `wrap`) + `golden_labeled_response` (real binary: WHOIS-batch/TIME-single/\nPRIVMSG-ACK/non-negotiating-inverse) + a `batch=<REF>` canonicalizer mask; 2 `golden_cap` LS snaps\nregenerated. Plan: `docs/superpowers/plans/2026-06-14-p11-slice155-labeled-response.md`.\n\n**Slice 159 (2026-06-14) shipped SASL** — the keystone client-auth cap (`docs/rfcs/ircv3/sasl-3.2.md`).\n**Architecture (user-locked decision): relay-to-services, NOT local validation** — leveva keeps no\naccount DB ([[iauth-subsumed-into-leveva]] / the slice-139 `ENCAP * SU` SoT), so it forwards the\n**opaque** base64 `AUTHENTICATE` exchange to a linked services agent (charybdis/atheme model) and\nrenders the verdict. Scope = framework + **PLAIN + EXTERNAL**. Pieces: pure `leveva::sasl`\n(`Mechanism{Plain,External}` + the IRCv3 400-byte chunking `chunks_for_wire`↔`Accumulator` + a\n`SaslSessions` cross-task rendezvous keyed by the client's **early-assigned UID** — lives **inside\n`Registry`** via `Registry::sasl()` to dodge the ~57 `ServerContext`-literal churn); a `sasl` CAPAB\ntoken (`PeerCaps::sasl`, **never** in `ours()` — leveva isn't a provider) + `PeerLinks::sasl_agent()`;\nthe **first dynamically-advertised + valued client cap** (`cap.rs` `apply`/`ls`/`req` gained a\n`sasl_available` arg — `sasl=PLAIN,EXTERNAL` in LS + ACK **only while an agent is linked**, else NAK,\nSASL 3.2 MUST; the static `SUPPORTED` table is untouched, `sasl` is injected/filtered at render);\n`session.rs` handles `AUTHENTICATE` **phase-independently** (like CAP, before the pending-complete\nguard — the whole exchange runs during CAP negotiation), assigns the early UID (kept across `433`),\nrelays `H`/`S`(+certfp for EXTERNAL)/`C`/abort, applies the resolved account at finalize (reuse\n`sasl_uid`); `s2s/sasl.rs`+`forward.rs` route the agent's inbound `ENCAP SASL C/D` + `SVSLOGIN` back\nto the in-flight client (consume, don't relay). Numerics `900`–`908`. Divergences: no reauth (`907`\nfor a registered client), no `cap-notify` NEW/DEL of `sasl`, opaque relay (no decode/validate/cache,\nno `902`), single agent. leveva-native (no differential), with a `sasl_proptest` **fuzzing** the\nchunk round-trip + a real-binary `golden_sasl` (full PLAIN vs a scripted services peer → `900`/`903`/\nWHOIS `330`; inverse = no agent → unadvertised/NAK/`904`). **Also fixed a latent\n`metrics_endpoint_proptest` red** a prior session had left (the `[\"CAP\"]` regressions seed): session-\nlayer verbs (CAP/QUIT/AUTHENTICATE) return before `command::dispatch`, the metering point, so they're\nnever counted — the test's QUIT-only carve-out was extended to all three. Plan:\n`docs/superpowers/plans/2026-06-14-p11-slice159-sasl.md`.\n\n**Slice 163 (2026-06-14) shipped `draft/metadata-2` (the metadata store + client command surface)**\n— the **framework half** of IRCv3 [metadata](../docs/rfcs/ircv3/metadata.md) (the fresh spec the\nuser dropped at `docs/rfcs/ircv3/metadata.md`), mirroring the framework-vs-behavior split (48/56/69).\nNew **`leveva::metadata`** (pure core + store): `key_valid` (charset `a-z0-9_./-`)/`value_valid`\n(`<=MAX_VALUE_BYTES`) fuzz targets; `MetaTarget{User(Uid)|Channel(folded)}`; `MetadataStore`\n(`HashMap<MetaTarget,BTreeMap>` values + `HashMap<Uid,BTreeSet>` subs) **inside `Registry`**\n(`registry.metadata()`, the SASL/sasl-sessions pattern → zero `ServerContext`-literal churn).

Numerics **761/766/770/771/772** + the METADATA\n`FAIL` codes via the slice-69 `stdreply` framework. Cap `DRAFT_METADATA_2` advertised **valued** to\n302+ (`draft/metadata-2=max-subs=30,max-keys=30,max-value-bytes=300` via `metadata::CAP_VALUE` — the\n**first valued static-`SUPPORTED` cap**, contrast dynamic `sasl`), bare otherwise;\n`ClientCaps.metadata` wired (the next-slice notification gate). **Permission (slice 163, no\nprivileged keys → every visibility `*`):** SET/CLEAR on self (`*`/own nick) or a channel you op\n(`Channels::is_op`) else `KEY_NO_PERMISSION`; GET/LIST open. **Deferred (each a follow-on): the\nnotification plane** (push `METADATA` to subscribers on a watched-key change — the behavior half),\n`before-connect`/registration burst, `SYNC`/`774 RPL_METADATASYNCLATER`/JOIN-sync, `760` WHOIS, S2S\npropagation, rate-limiting, the privileged/visibility system; the cap isn't required to use the\ncommand (lenient) + `batch`-dependency unenforced. leveva-native (no differential). Adding the cap to\n`SUPPORTED` regenerated the full-LS asserts + `supported_names` + 2 `golden_cap` + 1 `golden_setname`\n+ `golden_help_users` index snaps (METADATA added to help `COMMANDS`+index.md). Gate:\n`metadata_proptest` (5 props: validators-vs-model, store-vs-`BTreeMap`, subscribe-vs-`BTreeSet`+limit)\n+ `golden_metadata` (real binary, framing+correlation asserted like `golden_labeled_response`).

Spec lives in-repo at\n`docs/rfcs/ircv3/`.\n\n**Slice 72 (2026-06-10) shipped IP cloaking (`+x`)** — a port of Elemental-IRCd's\n`extensions/ip_cloaking.c`, the first non-IRCv3 *extension* on the track but it follows the\nsame leveva-native usermode pattern as `+W`/`+B`. New `leveva::cloak` (faithful FNV-1/32\n`fnv_hash(s,32)` + `cloak_ip`/`cloak_host`/`cloak`); `UserMode::Cloak` (`+x`, `0x0100`,\nappended last). Setting `+x` replaces the visible host with a deterministic cloak of the\n**original connect host** (new immutable `ClientRecord.orighost`, set at `try_claim`, never\ntouched by `set_host`); `-x` restores it. The host change is **distributed by reusing the\nslice-71 `chghost` plane** (`notify_co_members` + `local_chghost`/`ENCAP CHGHOST`) — so `+x`\nis deliberately **NOT** in `SEND_UMODES` (no double-propagation; the host change is the\npropagation, not the umode bit). `396 RPL_HOSTHIDDEN` added. Wire-safety invariant: `cloak`\nnever introduces a leading `:`. `+x` is client-settable (joins the `i|w|B` arm) AND allowed in\n`default-user-modes` (network-wide auto-cloak; `config/parse.rs` now accepts `x`) — a\ndefault-`+x` client is cloaked at registration (the C `check_new_user` path, in\n`session::finalize` before the burst). **Also (user request): clients are told their user\nmodes on connect** — `session::finalize` emits `:nick MODE nick :+<modes>` after the welcome\nburst (regenerated 4 registration snapshots: `004`→`oOiwraWBx` + the trailing MODE notice).\nGate: cloak/mode/numeric/registry/command/session/config units + `golden_ip_cloaking`\n(`127.0.0.1`→`127.0.y.p`) + `cloak_proptest` (the fuzz target). Plan:\n`docs/superpowers/plans/2026-06-10-p11-slice72-ip-cloaking.md`.\n\n**Slice 78 (2026-06-10) shipped CertFP** — charybdis-style TLS client-certificate\nfingerprints (researched against a fresh charybdis clone: `ircd/sslproc.c`/`m_certfp.c`/\n`m_whois.c:344`/`m_oper.c:120`/`s_user.c:734`). The first **TLS-identity** feature on the\ntrack and NOT a cap. New `leveva::certfp` (`fingerprint(der)` = lowercase-hex **SHA-256** of\nthe leaf cert DER via the `sha2` dep — the fuzz target; `from_peer_certs(Option<&[CertificateDer]>)`).\n**Key TLS pattern: an `AcceptAnyClientCert` `ClientCertVerifier` in `tls.rs`** — requests but\ndoes NOT require a client cert, accepts any issuer (self-signed is the norm; the fingerprint\nIS the identity) while still verifying the handshake signature via the ring provider's\n`signature_verification_algorithms`; `TlsEndpoint::new` switched `with_no_client_auth()` →\n`with_client_cert_verifier(...)`. `main.rs` pulls `tls_stream.get_ref().1.peer_certificates()`\n→ `from_peer_certs` → `serve_client(..,certfp)` → `Session::set_certfp` (new field+setter, the\n`set_websocket` pattern). **Single source of truth = `ClientRecord.certfp`** (new field + new\n`Registry::set_certfp`): finalize mirrors it; WHOIS and OPER read it back, so **no `Registered`\nfield** (dodged the ~23-literal churn). Surfaced as `276 RPL_WHOISCERTFP` (last extra-info line\nbefore 318, local+remote). **OPER gate:** `Operator.certfp: Option<String>` (`certfp \"...\"`,\n`opt_string`) — a block grants oper iff password verifies AND certfp matches case-insensitively;\na name+host+password match that fails certfp → **491** (charybdis parity), distinct from the\n464 password arm (precedence flag `certfp_mismatch`). **S2S = `ENCAP * CERTFP`** (new\n`s2s/certfp.rs::apply_encap_certfp` + `forward.rs` arm + burst appends `:<uid> ENCAP * CERTFP\n:<fp>` per local certfp user) — the slice-71 CHGHOST relay pattern (record source uid + onward-\nrelay verbatim). Divergences: **sha256-only** (charybdis defaults to deprecated sha1 + a method\nmenu); single-server-local notify (burst carries it, no live post-burst rebroadcast — leveva has\nno live UNICK introduce); `RemoteUser` untouched (WHOIS reads the registry record UNICK populates).\n**Gate incl. the crown-jewel `golden_certfp.rs`: a REAL TLS handshake** (`rcgen`-generated\nserver+client certs as dev-deps, a synchronous `rustls::StreamOwned` client presenting the\nclient cert) against a booted leveva → WHOIS 276 == independently-computed SHA-256 + certfp-\ngated OPER → 381. Plus `certfp_proptest.rs` + oper/whois/session/s2s units. Adding a 4th field\nto `Operator` touched 4 `tests/*_proptest.rs` literals (kill/oper/oper_tag/wallops → `certfp:\nNone`). Plan: `docs/superpowers/plans/2026-06-10-p11-slice78-certfp.md`.\n\n**BATCH track:** the `batch` cap is advertised (slice 155) and now produces TWO types:\n`labeled-response` (155, `leveva::labeled::wrap` over the direct-reply vector) and **`netsplit`\n(slice 157, 2026-06-14)** — `leveva::s2s::squit::netsplit_frame` wraps a server-split's QUIT flood\nin one batch per `batch`-capable local co-member, gated on `caps_of(recipient).batch`. The shared\nref source is `labeled::next_ref` (process-global hex counter; per-connection). `squit_subtree` was\nrestructured inline-deliver → per-recipient collect→deliver (split teardown helpers keep the single\nrelayed-QUIT path immediate; non-batch recipients byte-identical). **`netjoin` is the deferred\nfollow-on** (spread across many `NJOIN` calls during a burst → needs cross-message buffering until\nEOB, a distinct mechanism); `chathistory` needs a history store leveva lacks. The slice-156 \"NEXT =\nask the user\" list (SASL keystone / a batch slice / SendQ hardening / other IRCv3 caps) — batch is\nnow partly done (netsplit) and **SASL is DONE (slice 159)**; next IRCv3 candidate is METADATA\n(the new `docs/rfcs/ircv3/metadata.md`).\n\n**Slice 211 (2026-06-16) shipped `sts`** (IRCv3 Strict Transport Security) — the first cap on\nan **STS/TLS track**. It is **advisory-only**: stays *out* of the `SUPPORTED` registry (so\n`CAP REQ sts` NAKs and it never shows in `CAP LIST`) and is injected directly into the `LS`\ntoken list, **302+ only** (a bare valueless `sts` is useless). Pure core `sts::StsPolicy {\nduration, port, preload }` + `ls_value(secure) -> Option<String>`: `None` (disabled) unless a\nTLS client listener exists *and* `duration != 0`; plaintext → `port=<p>` (upgrade), TLS →\n`duration=<d>[,preload]` (persist; preload never over plaintext, per spec). Config\n`options { sts-duration N; sts-preload }` (boot-read, default off, `0` = off). Lives on\n`StatsConf.sts` (slice-206 churn-free bundling); `from_config` derives the port from the first\n`tls && !server_only && websocket.is_none()` listener. New `Session.secure` flag set by\n`serve_client` (TLS arm true / plaintext false) drives the per-connection token; `cap.apply`\ngained an `sts: Option<&str>` param. **Documented follow-ons:** REHASH-ability of the knobs +\nthe TLS port (boot-read for now, the flood 201→204 rhythm); wss connections advertised as\ninsecure (the secure-flag plumbing for the websocket path is out of scope). Gate: sts/cap/config\nunits + `tests/sts_proptest.rs` + `tests/golden_sts.rs`.\n\n**Slice 221 (2026-06-16) shipped `760 RPL_WHOISKEYVALUE`** — `draft/metadata-2` metadata in\n`WHOIS`. A WHOIS on a user with metadata set now emits `:<srv> 760 <requester> <target> <key>\n<vis> :<value>` lines, **gated on the requester's `client.caps.metadata`** (no cap → no 760, the\ninverse), one per key in sorted `MetadataStore::list` order, before the\n317/318 tail; fires for remote targets too (metadata is UID-keyed + network-wide via the\nslice-189 burst / slice-177 propagate). Pure fuzz seam `command::whois::whois_keyvalue_lines`.\n\n**Slice 223 (2026-06-16) shipped the privileged-key / restricted-visibility system** — the\n**last** `draft/metadata-2` deferral (named by slice 221). A metadata key is *oper-restricted*\n(settable/viewable only by `+o`/`+O`, visibility token `oper` not `*`) iff it begins with the\nbuilt-in `priv.` prefix (`metadata::PRIV_KEY_PREFIX`) **or** matches a REHASH-able\n`options { oper-keys \"<glob>\" }` allowlist (user-locked *prefix+config* scheme; the\nslice-204/210/212 `ConfStore` `live_oper_keys` seam — `Options.oper_keys` →\n`ConfBlocks`/`ConfStore` `ArcSwapOption<Vec<String>>`, REHASH auto-reseeds via `config_conf`).\nA non-oper is refused SET/GET (`KEY_NO_PERMISSION`), omitted from LIST/760 WHOIS, skipped by\nCLEAR (non-oper CLEAR clears only non-restricted keys via per-key `remove`, not the blanket\n`clear`), and never pushed a restricted key via `notify_subscribers` (covers the local +\ninbound-S2S `s2s::metadata::apply_encap_metadata` paths — they share the fn). **Pure fuzz seam =\n`metadata::key_visibility(key, oper_keys) -> Visibility{Everyone,Oper}`** (label `*`/`oper`,\n`is_restricted`); `whois_keyvalue_lines` + `rpl_keyvalue` gained a visibility param. Gate adds the\nconfig-driven `golden_metadata_priv` (real binary booted with `oper-keys` + an `operator` block:\nopered alice sets `priv.note`+`secret-score`→`761 oper`, mortal bob can't SET/GET/LIST them) +\nthe `metadata_proptest` `key_visibility_is_total_and_contractual` fuzz. **The `draft/metadata-2`\ntrack is now feature-complete except `SYNC`/`774`/`RATE_LIMITED`** (still deliberately out of\nscope). Also corrected two stale doc comments (\"no registration metadata burst\" — slice 189 added\nit; \"no privileged-key visibility\").

read all 25 files. Here is my ranked list of blog-post candidates, told with the concrete specifics a systems reader would want.\n\n---\n\n## Ranked candidate topics\n\n### 1. The channel-timestamp merge fight that silently stripped ops from everyone\n**Story:** On the live network, two servers disagreed about a channel's creation timestamp because a server learning a channel via a join re-clocked `created_at` with its own local clock — so the two nodes differed by exactly the propagation latency. The TS6-style `CHANTS` arbitration (\"oldest timestamp wins, younger side's chanops get deopped\") then deopped whichever server *learned of the channel later*. Across recreate/relink flaps this stripped ops from **every** side. Observed in production as `#leveva` sitting at `+nt` with zero ops and `-o Xe`. A later variant (slice 215): upgrading one server to v0.1.0 and relinking made it strip channel modes that should have survived a merge — `#xe` lost `-oo`, `-R *`, and a peer's manual `+ooo` 40s later. The fix required carrying the channel TS as a wire parameter on the NJOIN join-propagation verb, and reasoning carefully about *which* path (burst vs live) owns arbitration so the fix for one didn't defeat the other.\n**Why it's interesting:** This is a textbook distributed-consensus failure — clock skew feeding a \"lowest timestamp wins\" tiebreak that then mutates authority state — playing out in a real netsplit/merge on a running network, not a whiteboard. The subtlety that fixing the *live* path left the *burst* path broken (same bug, two code paths) is exactly the kind of thing that bites real distributed systems.\n**Source:** `leveva-live-join-njoin.md`\n\n### 2. The bare UID in NAMES: diagnosing a cross-server identity desync by dialing each node directly\n**Story:** On the production network a channel member showed up as a raw UID (`4LTKAAAAF`) instead of a nick, but only on some servers. Root cause (slice 86): the S2S user-introduction verb `UNICK` was emitted **only** in the link-time burst. A client who registered *after* a link was already up was never announced to the peer — every other relay (JOIN/PART/PRIVMSG/QUIT) fired, so the peer received actions from a UID it had no record for, delivered them with the raw UID prefix, and silently dropped the user from remote NAMES (the reply builder does `filter_map(record_of)`). The lesson: every outbound S2S relay needs *both* a live path and a burst path, and the introduction was the one verb that only had the burst path. The diagnostic technique is itself blog-worthy: since the front door (`irc.xeserv.us:6667`) load-balances you onto an arbitrary member, you reach one specific server directly at `<servername>.alrest.xeserv.us` and compare the same channel across servers at different hop distances to localize exactly where nick resolution breaks.\n**Why it's interesting:** A genuine \"it works on my machine / works within one hop\" distributed bug, plus a concrete field-debugging methodology for a multi-server system where the nodes disagree.\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`, `leveva-prod-shadownet-per-server-probe.md`\n\n### 3. A bare unknown server command is *fatal* in 1997 IRCnet — so every extension has to be tunneled\n**Story:** Sending a bare `:sid CAPAB …` (a new leveva capability-negotiation verb) to the faithfully-ported C oracle makes it reply `SQUIT … :Success` + `ERROR :Closing Link` and drop the link. But `ENCAP` is routed to `m_nop` and tolerated. This was verified against the in-process 1997-lineage oracle. The consequence became an architectural law: **every leveva-native S2S extension verb must ride inside `ENCAP`** to keep a strict IRCnet peer alive (CAPAB, REDACT, CHGHOST, CERTFP, channel-TS, user-TS, METADATA, KNOCK, RESV, KLINE all became `ENCAP *`-wrapped), while real IRCnet verbs (AWAY, INVITE, WALLOPS, KILL) stay first-class. Timestamps ride `ENCAP` in unix nanoseconds — which a real IRCnet oracle simply routes to `m_nop` and ignores, so the same bytes are safe on both.\n**Why it's interesting:** Protocol archaeology with teeth — a design constraint on a modern daemon dictated by the crash behavior of 27-year-old C, *discovered empirically by running that C as a test oracle*. It's a clean illustration of \"extension tunneling to stay wire-compatible with something unforgiving,\" like TLS extensions or IP options.\n**Source:** `leveva-s2s-peer-caps.md`, `leveva-s2s-notify-propagation.md`, `leveva-ts-and-link-fixes-131-133.md`\n\n### 4. The memory leak that wasn't: measuring instead of assuming\n**Story:** A user reported a memory leak. Rather than inspecting internal stores, the demand was for real measurement: boot real daemons, drive load with a Python socket harness, sample `/proc/<pid>/VmRSS`. Result — **no unbounded leak anywhere**: connection churn flat at 16764 KB from 11k→30k connections; unique-channel churn flat (empty channels reaped on part); S2S kill/relink plateaus (subtree reclaimed); true half-open (SIGSTOP the peer) reaps at t+4s under a 2s ping-freq. The perceived \"leak\" was two things: (1) the half-open keepalive works, but at the default 90s ping-freq it takes 180s, so anyone watching for under ~3 minutes sees remote users persist (working-as-designed-but-slow), and (2) the introduction-ghost state from bug #2 above. Bonus test-harness gotcha: under `ping-freq 2`, passive Python clients that don't answer PING get ping-timed-out in ~4s and vanish on their own, confounding the measurement.\n**Why it's interesting:** A crisp \"your intuition about the bug is the bug\" story plus an honest, reproducible measurement methodology — the opposite of the usual hand-wavy \"we think it leaks.\"\n**Source:** `leveva-s2s-introduce-and-leak-audit.md`\n\n### 5. Building a 1997 C daemon as an in-process differential oracle — and the RFC-vs-reality verdicts it produced\n**Story:** The core testing rig boots a mechanically-ported Rust copy of 1997 IRCnet ircd *in-process*, drives both it and the greenfield daemon over real loopback TCP, and diffs their responses reduced to a skeleton of 3-digit numeric reply codes. Over ~20 command clusters this produced surprising verdicts. The best: for `PRIVMSG`/`NOTICE` with missing params, the oracle emits `461 ERR_NEEDMOREPARAMS` — because its *parser* enforces min-params=2 before the handler ever runs, so the C code never emits the RFC-specified `411`/`412` at all. The IRCnet daemon quietly diverges from the RFC it nominally implements, and the greenfield daemon had to be made *bug-for-bug* compatible. This crystallized a governance rule: \"if the oracle supports something the new daemon doesn't, that's a bug — close it,\" reserved against the opposite cases where the *new* daemon is RFC-correct and the oracle is quirky (bare `WHO` → the oracle 461s where RFC 2812 says list; second `+k` → 467 `ERR_KEYSET`; LIST's obsolete leading `321`).\n**Why it's interesting:** Differential testing against a legacy implementation as ground truth, and the philosophical knot of \"which one is *right* when the spec, the incumbent, and the newcomer all disagree?\" That's a real question in any clean-room reimplementation (browsers, SQL engines, compilers).\n**Source:** `leveva-native-oracle-harness.md`\n\n### 6. A property test that surfaced a genuine IRCv3 wire-format ambiguity (the lone `+`)\n**Story:** A SASL chunking round-trip property test flaked on any payload of length ≡ 1 (mod 400) ending in `+` (minimal repro: the bare string `\"+\"`). The initial \"exact-multiple-of-400\" guess was wrong — the real cause is that `AUTHENTICATE +` is *reserved* as the IRCv3 empty-payload sentinel, so a data chunk equal to the bare string `+` is **unrepresentable on the wire**, full stop. It's a genuine spec ambiguity, unfixable in the chunker (a non-final chunk must be exactly 400 chars — that length *is* the \"more follows\" signal), and unreachable for valid input (base64 length is always a multiple of 4, so a final chunk is never length 1). The fix was not to touch the chunker but to document the representability contract and tighten the fuzz domain to the real base64 alphabet — plus a test that pins the exact swallowed-`+` boundary.\n**Why it's interesting:** Fuzzing found a corner of the *specification*, not a bug in the code — and the correct response was to prove the property was impossible rather than \"fix\" it. A great cautionary tale about over-broad generators asserting impossible invariants.\n**Source:** `leveva-sasl-chunking-proptest-flake.md`\n\n### 7. Why a lone IRCnet server refuses to create a channel — the `is_split` burst-symmetry trap\n**Story:** Writing a differential test for the S2S burst revealed deep C behavior: a lone protocol-mode oracle boots with `iconf.split=1` and never clears it (its `split_minservers`/`minusers` are unconfigured at -1), so it is permanently `is_split()`, and a split IRCnet server *refuses to create a `#` channel*. Therefore a local channel can never appear in that server's outbound burst — burst symmetry could only be tested by seeding a local *user*, and NJOIN agreement had to be proven by having a peer burst a channel first, then joining the now-existing channel locally (so the non-null channel pointer skips the split-create block). Related archaeology: the PASS version token must be the exact IRCnet patchlevel `0211030000` or `get_version` rejects it as `SV_OLD`.\n**Why it's interesting:** A pile of load-bearing, undocumented legacy invariants that only surface when you try to make two implementations agree byte-for-byte — the reverse-engineering texture that makes reimplementation hard.\n**Source:** `leveva-native-oracle-harness.md`\n\n### 8. The maintainer overruling the AI's \"documented divergence\" on TS6 correctness\n**Story:** The agent had shipped a deliberate divergence from TS6: on a channel-merge loss it kept the loser's `+R` reop list unioned in (rather than wiping it with the bans/except/invex masks), with a plausible rationale (\"benign for the native `+R`, lets the inline reop restore the loser's members\"). The human overruled it as a **hard rule**: on a merge loss the loser drops *all* modes including list masks and adopts the winner's — no exceptions, no deferral. That forced a real restructuring: the reop enforcement could no longer read the loser's own (now-wiped) `+R` list, so it had to be rebuilt as an end-of-burst sweep that fires *after* the winner's `+R` masks arrive in burst order.\n**Why it's interesting:** A concrete instance of an AI making a reasonable-sounding local optimization that violated a global correctness invariant, and a human catching it — the human/AI design-authority tension made specific, on a genuine distributed-consistency rule (TS6).\n**Source:** `leveva-ts6-reop-must-wipe.md`, `leveva-live-join-njoin.md`\n\n### 9. Deliberate heresies against 30-year-old IRC tradition\n**Story:** Three considered breaks with IRC orthodoxy, each with a real rationale. (1) **UTF-8-only:** invalid UTF-8 in a client frame is rejected at the single byte→message parse boundary (mapped to an IRCv3 `INVALID_UTF8` FAIL) rather than lossy-decoded into U+FFFD as the C daemon does — enforced at parse so it \"transitively proves\" every downstream consumer is UTF-8-safe without re-checking, because a parsed message's fields are `String`. (2) **2048-grapheme lines** instead of the sacred 512-byte limit — measured in UAX-#29 grapheme clusters (not bytes), advertised as `LINELEN=2048`, with a framer DoS ceiling of 64 bytes/grapheme (covers ZWJ emoji families). (3) **Port-based client/server routing:** the daemon decides client-vs-server link by the *listener's* `server-only` flag, deliberately *not* by content-sniffing the PASS/SERVER handshake the way IRCnet does on a shared port — a cleaner separation, explicitly chosen and defended against \"fixing\" it back.\n**Why it's interesting:** Opinionated modernization of a legacy wire protocol, with the tradeoffs named (grapheme vs byte limits, parse-boundary type-safety as a security argument). Systems readers love \"we broke compatibility here, on purpose, and here's why.\"\n**Source:** `leveva-utf8-only-parse-boundary.md`, `leveva-linelen-2048-graphemes.md`, `leveva-s2s-port-based-routing.md`\n\n### 10. Porting a 1997 \"fakelag\" penalty clock — and finding dead privileges waiting for it\n**Story:** The flood-protection port was triggered by a smell: two operator privileges, `CanFlood` and `NoPenalty`, were parsed from config blocks but **read nowhere** in the codebase — dead flags waiting for a system that \"appeared in no progress log.\" The original algorithm was recovered from C git history: each command charges `since += 1 + len/100`; the clock idle-decays to real time so only a faster-than-1-cmd/sec client accumulates penalty; beyond a 10s ceiling (\"fakelag\") the server *delays* the connection's next read rather than disconnecting, pacing a flooder's input toward 1 cmd/sec while its fan-out and keepalive keep flowing; a hard kill fires only past a recvQ threshold. The delay half was reimplemented as a tokio `sleep_until` wrapped around the read arm of the connection's `select!`, throttling *input* only.\n**Why it's interesting:** Reverse-engineering an anti-abuse rate-limiter from a legacy codebase, the \"dead config field points at a missing feature\" detective beat, and a neat idiomatic-async reimplementation of a mechanism the C daemon achieved by stalling its recvQ drain.\n**Source:** `leveva-flood-penalty.md`\n\n### 11. Property tests that hand-copy a lookup table and flake stochastically forever after\n**Story:** A recurring, subtle testing failure mode: several property tests re-encoded an *assumption* about a command table instead of calling the real function — a hand-copied list of recognized `STATS` selector letters, an assumed flat cost-of-1 for flood penalties, an assumption that server-info verbs answer locally. When a later change grew the underlying table (a new STATS letter, a `WHO`/`LIST` flood surcharge of +4/+5, or a `hunt_server <target>` argument that short-circuits to `402`), the test would fail **only on unlucky random seeds** — passing in a single-file run and surfacing days later as an \"unrelated\" red in the full suite. The lesson: assert against the real function (`command_penalty`, the actual dispatcher), never a copy, and run the *whole* suite because the failing seed is random.\n**Why it's interesting:** A precise, reusable articulation of a property-testing anti-pattern (the model drifting out of sync with the implementation) and why it produces the worst kind of flake — non-local, non-deterministic, and misattributed.\n**Source:** `leveva-proptest-model-staleness.md`, `leveva-hunt-server-proptest-hazard.md`\n\n### 12. The auth subprocess that existed only to protect a single-threaded event loop\n**Story:** IRCnet's `iauth` ran as a separate child process talking a `<id> <category> <info>` pipe protocol to the main daemon. The reason was purely architectural: the C ircd is a single-threaded select/poll loop, and blocking DNS/ident/proxy-probe I/O had to be exiled to another process to keep the loop responsive. Under tokio that entire motivation evaporates — so the whole separate-process + pipe design was dropped and auth folded back into the daemon as native async modules (ident runs concurrently with the NICK/USER handshake, verdict stashed in the session so either arrival order works). A planned intermediate \"spawn it over a socketpair\" step was skipped as throwaway.\n**Why it's interesting:** A clean case of an architecture that existed *solely* as a workaround for a concurrency model, and what happens to it when the concurrency model changes — the kind of \"why does this weird boundary exist\" story that generalizes far beyond IRC.\n**Source:** `iauth-subsumed-into-leveva.md`\n\n---\n\n**Honorable mentions** (usable as supporting color, not full posts): the network-wide `msgid`/`@time` \"introducing-server-assigns, never re-mint\" model for cross-server message identity; the two harness gotchas where dropping a client handle silently reaps its user via EOF, and a fixture's per-IP CIDR connection cap (`10.2` = 2 clients/32) that broke any test opening a 3rd client; and the UNICK/NJOIN-vs-SJOIN \"divergence\" that turned out to be the agent confusing IRCnet's protocol lineage with Undernet/TS6, caught by an adversarial design reviewer and corrected to full agreement (`leveva-native-oracle-harness.md`)."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":41092,"cache_read_input_tokens":62878,"output_tokens":9310,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":41092},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":9310,"cache_read_input_tokens":62878,"cache_creation_input_tokens":41092,"cache_creation":{"ephemeral_5m_input_tokens":41092,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011CchkLwx7zTqR948htua6r","attributionAgent":"Explore","type":"assistant","uuid":"bf3f3c70-6868-4210-814f-475ee5145879","timestamp":"2026-07-04T21:46:31.181Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

Use this skill whenever the user wants to autonomously optimize code by running iterative experiments — tuning search ranking, scoring functions, prompt templates, weight parameters, algorithm configurations, or any logic where changes can be evaluated against a numerical metric. Also trigger when the user mentions 'autoresearch', 'overnight optimization', 'autonomous experiments', 'autoresearch loop', 'Karpathy loop', or wants to 'let Claude Code optimize this while I sleep'. This skill generates the full experiment harness: instructions.md, eval script, test data template, and launch prompt — scoped to their specific codebase.\n- autoresearch:autoresearch-discover: Scan a codebase to find files and functions where autoresearch could be applied — code with tunable parameters, magic numbers, scoring logic, or prompt templates that could be optimized against a measurable metric. Use when the user wants to find optimization candidates, asks 'where could I use autoresearch?', 'what can I tune?', 'find tunable code', or wants to discover what's optimizable before running /autoresearch.\n- tigris-storage:tigris-access-keys: Use when creating, listing, assigning, or deleting access keys for Tigris Storage\n- tigris-storage:tigris-authentication: Use when authenticating with Tigris, managing credentials, or setting up the CLI\n- tigris-storage:tigris-buckets: Use when creating, configuring, or deleting Tigris buckets — includes regions, tiers, CORS, migrations, TTL, notifications, snapshots, and forks\n- tigris-storage:tigris-iam: Use when managing IAM policies, users, and permissions in a Tigris organization\n- tigris-storage:tigris-objects: Use when uploading, downloading, listing, moving, deleting, or presigning objects in Tigris Storage\n- product-management:competitive-brief: Create a competitive analysis brief for one or more competitors or a feature area.

Use when running a weekly, monthly, or quarterly metrics review, investigating a sudden spike or drop, comparing performance against targets, or turning raw numbers into a scorecard with recommended actions.\n- product-management:product-brainstorming: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring a new opportunity, generating solutions to a product problem, stress-testing an idea, or when a PM needs to think out loud with a sharp sparring partner before converging on a direction.\n- product-management:roadmap-update: Update, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.\n- product-management:sprint-planning: Plan a sprint — scope work, estimate capacity, set goals, and draft a sprint plan. Use when kicking off a new sprint, sizing a backlog against team availability (accounting for PTO and meetings), deciding what's P0 vs. stretch, or handling carryover from the last sprint.\n- product-management:stakeholder-update: Generate a stakeholder update tailored to audience and cadence.

Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- let-fate-decide:let-fate-decide: Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.\n- xe-design:xe-design-system: A warm, Gruvbox-rooted design system derived from xeiaso.net. Use for personal-blog, technical-educator, or character-driven content that wants serif headlines, parchment surfaces, and chat-bubble layouts.

Use when prior agent sessions may contain relevant insights, decisions, attempts, or transcript context.\n- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies\n- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints\n- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup\n- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation\n- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements\n- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session\n- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes\n- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code\n- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback\n- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions\n- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always\n- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code\n- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a GitHub pull request; for your working diff use /code-review\n- security-review: Complete a security review of the pending changes on the current

Here's the deliverable.\n\n---\n\n# Memory-management & string fossils in IRCnet ircd 2.11\n\nA ranked tour of RAM-scarcity artifacts in `var/ircd/common/` and `var/ircd/ircd/`. Every finding is a design choice that only makes sense when a server had 16–64 MB and every client structure was a line item.\n\n---\n\n## 1. The partial-struct allocation trick (`CLIENT_REMOTE_SIZE`)\nThe crown jewel. The `aClient` struct is deliberately split so remote clients get allocated **only the prefix up to the `count` field**, and the entire local-only tail (input buffer, sendQ/recvQ dbufs, socket host, password, auth fd…) is never allocated.\n\n`common/struct_def.h:577-578`:\n```c\n#define\tCLIENT_LOCAL_SIZE sizeof(aClient)\n#define\tCLIENT_REMOTE_SIZE offsetof(aClient,count)\n```\n`common/struct_def.h:530-538` — the comment marking the cut line:\n```c\n\t/*\n\t** The following fields are allocated only for local clients\n\t** ... The first of them *MUST* be the \"count\"--it is the field\n\t** to which the allocation is tied to! *Never* refer to\n\t** these fields, if (from != self).\n\t*/\n\tint\tcount;\t\t/* Amount of data in buffer */\n\tchar\tbuffer[BUFSIZE]; /* Incoming message buffer */\n```\n`ircd/list.c:92-105` — the allocator that reads the offset as a length and `malloc`s a truncated struct:\n```c\nReg\tunsigned size = CLIENT_REMOTE_SIZE;\nif (!from)\n\tsize = CLIENT_LOCAL_SIZE;\ncptr = (aClient *)MyMalloc(size);\nbzero((char *)cptr, (int)size);\n```\n- **Then:** On a hub relaying 5,000 remote users, skipping the ~600-byte local tail (a 512-byte `buffer` plus two dbuf headers, sockhost, passwd) saves multiple megabytes of otherwise-dead RAM per struct.\n- **Now:** This is undefined behavior waiting to happen — a single mis-predicated field access on a remote client reads past the allocation, and the invariant is enforced only by a scary comment. Rust makes this literally unexpressible; you'd model it as an `enum { Local(Box<LocalData>), Remote }` and the compiler guarantees you can't touch `LocalData` on a remote.\n\n## 2. Interior self-pointers: `name = namebuf`\nEvery client carries both a `char namebuf[NICKLEN+1]` and a `char *name` that usually points *into its own struct* — but is re-pointed at the server's or user's namebuf when the client becomes one of those.\n\n`ircd/list.c:121`: `cptr->name = cptr->namebuf;`\n`ircd/list.c:226`: `cptr->name = serv->namebuf;` (server name lives in a *different* struct)\n`common/struct_def.h:526-527`:\n```c\nchar\t*name;\t\t/* Pointer to unique name of the client */\nchar\tnamebuf[NICKLEN+1]; /* nick of the client */\n```\n- **Then:** Indirection through one pointer lets `->name` transparently follow the nick, a server name, or a masked identity without copying the string on every reference.\n- **Now:** The struct is non-movable and non-`memcpy`-able (the pointer would dangle), the pointer can outlive the buffer it aims at, and it defeats every bounds check. Rust forbids self-referential structs outright without `Pin` + `unsafe`; the borrow checker exists specifically to stop this.\n\n## 3. The `char sip[1]` struct-hack (flexible array member before C99)\n`anUser` ends with a 1-byte array that is deliberately over-allocated to hold an IPv4-or-IPv6 string.\n\n`common/struct_def.h:470-472`:\n```c\n\t\t\t\t/* sip MUST be the last in this struct!!! */\n\tchar\tsip[1];\t\t/* ip as a string, big enough for ipv6\n\t\t\t\t * allocated to real size in make_user */\n```\n`ircd/list.c:189`: `user = (anUser *)MyMalloc(sizeof(anUser) + iplen);`\n- **Then:** One allocation instead of two (struct + separate string), and IPv4 users don't pay for IPv6-sized storage — the array is sized to the *actual* address length per user.\n- **Now:** Reading `sip[5]` is formally out-of-bounds on the declared `[1]`; the whole thing rides on `MUST be the last` staying true across edits. Rust's DSTs / a trailing `[u8]` need `unsafe` and manual layout; the idiomatic answer is just `String` or `IpAddr`.\n\n## 4. `dbufbuf` sized to fit exactly one memory page\nThe dynamic-buffer pool block is hand-tuned so the struct + malloc overhead lands on a 2 KB page boundary.\n\n`common/dbuf_def.h:64-73`:\n```c\n** If it was possible, this would compile to be exactly 1 memory\n** page in size. 2048 bytes seems to be the most common size, so\n** as long as a pointer is 4 bytes, we get 2032 bytes for buffer\n** data after we take away a bit for malloc to play with. -avalon\ntypedef struct dbufbuf {\n\tstruct\tdbufbuf\t*next;\n\tchar\tdata[2032];\n} dbufbuf;\n```\n- **Then:** Matching the page size and leaving 16 bytes \"for malloc to play with\" avoids straddling pages and fragmenting the allocator — real wins when VM pages are precious.\n- **Now:** `2032` assumes 4-byte pointers (it silently mis-sizes on any 64-bit box), and the magic number is pure folklore. Rust's `BytesMut`/`Vec` sidestep the whole hand-tuning.\n\n## 5. The `dbuf` bufferpool: a preallocated freelist with byte-budget accounting\nInstead of trusting `malloc`, the server carves one big slab at boot into a linked freelist and refuses to exceed a computed pool ceiling.\n\n`common/dbuf.c:36-60` (init slab + freelist):\n```c\nu_int\tpoolsize = (BUFFERPOOL > 1500000) ? BUFFERPOOL : 1500000;\ndbufbuf\t*freelist = NULL;\n...\nnb = poolsize / sizeof(dbufbuf);\nfreelist = (dbufbuf *)malloc(nb * sizeof(dbufbuf));\n```\n`common/dbuf.c:77-80` — allocation *fails on purpose* when the pool is exhausted, returning `-2` \"not fatal, go increase poolsize\":\n```c\nif (istat.is_dbufuse * DBUFSIZ > poolsize)\n {\n\tistat.is_dbufuse--;\n\treturn -2;\t/* Not fatal, go back and increase poolsize */\n }\n```\n`common/struct_def.h:81-82` — the pool ceiling is a compile-time formula over `MAXCONNECTIONS`/`MAXSERVERS`.\n- **Then:** A bounded, pre-reserved pool means a flood can't OOM the box; the server sheds load (drops slow clients) instead of dying, and freelist reuse avoids `malloc` churn under high message rates.\n- **Now:** It reimplements the allocator badly (`is_dbufuse`, `is_dbufmax`, `is_dbufnow` counters all hand-maintained), and a miscount silently leaks or double-frees pool blocks. Rust would use a real arena/`bytes` crate with the accounting for free.\n\n## 6. Hand-rolled `MyMalloc` with a `\"VAVA\"` magic-byte canary\nEvery allocation is wrapped to stash the original pointer + size + a 4-byte trailer sentinel, so `MyFree`/`MyRealloc` can detect heap corruption manually.\n\n`common/support.c:557-559`:\n```c\nbcopy((char *)&ret, ret, SZ_CH);\nbcopy((char *)&x, ret + SZ_CH, SZ_ST);\nbcopy(\"VAVA\", ret + SZ_CHST + (int)x, 4);\n```\n`common/support.c:637-639` — the check on free:\n```c\nif (bcmp((char *)k, \"VAVA\", 4) || (j != x))\n\tdumpcore(\"MyFree %#x %ld %#x %#x\", x, i, j, ...);\n```\nPlus a global `marray[100000]` table tracking every live pointer (`support.c:561-568`).\n- **Then:** No valgrind/ASan in the '90s, so a homemade guard-byte + pointer registry was the only way to catch the double-frees and overruns that plagued a long-lived C daemon.\n- **Now:** It's a bespoke, unsynchronized, size-limited (100k entries) shadow heap that itself can corrupt memory, and `bcopy`-into-offsets defeats the type system entirely. Rust's ownership model makes the entire mechanism unnecessary.\n\n## 7. `union Link` — one intrusive node type overloaded for six pointer kinds\nA single `SLink` struct threads channel lists, invite lists, whowas chains, conf chains, and more, with a `union` payload reinterpreted by context.\n\n`common/struct_def.h:667-678`:\n```c\nstruct\tSLink\t{\n\tstruct\tSLink\t*next;\n\tunion {\n\t\taClient\t*cptr;\n\t\taChannel *chptr;\n\t\taConfItem *aconf;\n\t\taListItem *alist;\n\t\tchar\t*cp;\n\t\tint\ti;\n\t} value;\n\tint\tflags;\n};\n```\n- **Then:** One allocator (`make_link`, `list.c:517`) and one node layout for every linked list in the server — minimal code, minimal per-node overhead, no generics in C.\n- **Now:** Nothing enforces that you read back the same union arm you wrote; a `value.chptr` stored and read as `value.cptr` is a silent type confusion. Rust's tagged enums carry the discriminant and check it; an untagged `union` read is `unsafe` precisely because this is a footgun.\n\n## 8. Global mutable `sendbuf[2048]` formatted with unchecked `vsprintf`\nEvery outbound line is built in one of two shared static buffers, formatted with `vsprintf` (no size argument), and only *afterward* clamped to 512.\n\n`common/send.c:31-36`:\n```c\nstatic\tchar\tsendbuf[2048];\nstatic\tchar\tpsendbuf[2048];\nstatic\tint\tsentalong[MAXCONNECTIONS];\n```\n`common/send.c:367-376` — the overflow is structural: the write happens, *then* the length is inspected:\n```c\nlen = vsprintf(sendbuf, pattern, va);\nif (len > 510)\n\tlen = 510;\nsendbuf[len++] = '\\r';\n```\n- **Then:** Two reused 2 KB scratch buffers for the whole process cost 4 KB total instead of a per-message allocation — trivially cheap and cache-friendly on a single-threaded server.\n- **Now:** `vsprintf` into a fixed buffer with attacker-influenced `%s` args is the textbook remote overflow; the `> 510` check is cosmetic because the smash already occurred. And the shared global buffer makes the code fundamentally single-threaded. Rust's `write!` into a sized `String`/`ArrayString` can't overflow, and `&mut` aliasing rules kill the shared-global pattern.\n\n## 9. `BUFSIZE 512` — the \"*DONT* CHANGE THIS*\" load-bearing constant\n`common/struct_def.h:57`:\n```c\n#define\tBUFSIZE\t\t512\t\t/* WARNING: *DONT* CHANGE THIS!!!! */\n```\n…one of a cluster of screaming constants (`CHIDLEN`, `SIDLEN`, `MAXMODEPARAMS` all carry the same `*DONT* CHANGE THIS!!!!` at lines 63-67).\n- **Then:** The RFC 1459 512-byte line limit is baked into hundreds of fixed `char[BUFSIZE]` stack buffers; the shout is a warning that the number is duplicated as an assumption everywhere, not a tunable.\n- **Now:** A magic number whose safety depends on grep-and-pray consistency across the tree; modern protocols (IRCv3 message tags) needed exactly this to grow and couldn't. Rust would make it a `const` the buffers derive from, checked at compile time.\n\n## 10. Manual refcounting with a magic sentinel for loop detection\n`anUser`/`aServer` blocks are shared and hand-refcounted; `free_user` decrements and, to catch double-frees, poisons the count with a specific magic number.\n\n`common/struct_def.h:443-446`: `int refcnt; /* Number of times this block is referenced ... */`\n`ircd/list.c:251-297`:\n```c\nif (--user->refcnt <= 0)\n{\n\t/* XXX: Remove loop detection before 2.11.0 - jv */\n\tif (user->refcnt == -211001)\n\t{\n\t\tsendto_flag(SCH_ERROR, \"* %p free_user loop ...\");\n\t\treturn;\n\t}\n\t...\n\tuser->refcnt = -211000; /* For loop detection */\n```\n- **Then:** Shared user/server records (a user is pointed at by its client, its server's `by`, and N whowas slots) needed manual refcounts, and encoding a \"being freed\" state as `-211000` avoided adding a whole extra field per struct.\n- **Now:** A refcount that doubles as a state machine via hardcoded sentinels (`-211001`, `-211000`) is a debugging nightmare, and the `XXX: Remove ... before 2.11.0` comment reveals it shipped anyway. Rust's `Rc`/`Arc` make refcounting safe, automatic, and impossible to double-free.\n\n## 11. Byte-granular memory accounting sprinkled through the logic\nThe server tracks its own heap usage down to individual strings, with `+= strlen(x)+1` bookkeeping interleaved into every alloc/free path.\n\n`common/struct_def.h:814-844`: a wall of `u_long is_chanmem, is_hchanmem, is_cchanmem, is_awaymem, is_banmem, is_confmem, is_wwawaysmem, is_authmem …`\n`ircd/list.c:159`: `istat.is_authmem -= strlen(cptr->auth) + 1;`\n`ircd/list.c:303-304`:\n```c\nistat.is_away--;\nistat.is_awaymem -= (strlen(user->away) + 1);\n```\n- **Then:** Operators used `STATS` to watch RAM by category and tune `MAXCONNECTIONS`/pool sizes on a box where 8 MB of away-messages mattered; the server literally reported its own footprint by feature.\n- **Now:** Every one of these hand-maintained counters is a place to desync from reality (a missed `-=` on an error path silently corrupts the stats), and `strlen` on free assumes the string was never mutated. It's manual instrumentation that a modern allocator or `jemalloc` stats provide for free.\n\n## 12. Prime-sized hash tables scaled off `MAXCONNECTIONS`\nHash tables are sized to `1.75 × MAXCONNECTIONS`, then rounded *up to the next prime* by trial division at boot.\n\n`ircd/hash_def.h:30-31`:\n```c\n#define\tHASHSIZE\t((int)((float)MAXCONNECTIONS*1.75))\n#define\tCHANNELHASHSIZE\t((int)(((float)MAXCONNECTIONS*1.75)/2.0))\n```\n`ircd/hash.c:231-258` — `bigger_prime()` sieves upward by trial division:\n```c\nif (size % 2 == 0) /* Make sure it's odd because... */\n\tsize++;\nfor ( ; ; size += 2) /* ...no point checking even numbers - Core */\n```\n- **Then:** A prime modulus minimizes collisions for the cheap multiplicative string hash, and sizing off `MAXCONNECTIONS` right-sizes the table to the box's configured capacity — you don't waste a 64 K-bucket table on a 256-user leaf.\n- **Now:** Fixed at boot with no resize-under-load, tied to a compile-time max, and the collision behavior lives in a hand-hashed `%_HASHSIZE` scattered across `hash.c`. Rust's `HashMap` grows dynamically with a DoS-resistant hasher and none of this ceremony.\n\n---\n\n**Honorable mention** — the whowas history is a fixed circular buffer sized `MAXCONNECTIONS*2` with slot reuse (`ircd/whowas.c:23,37`: \"referenced like a circular loop. Should be faster and more efficient.\" / `int ww_index = 0, ww_size = MAXCONNECTIONS*2;`), and `make_client` still carries `cptr->next = NULL; /* For machines with NON-ZERO NULL pointers >;) */` (`list.c:116`) — a comment defending against architectures where the null pointer isn't all-zero-bits, a portability worry that predates the modern internet as thoroughly as anything in the tree."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":926,"cache_read_input_tokens":60899,"output_tokens":5883,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":926},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":5883,"cache_read_input_tokens":60899,"cache_creation_input_tokens":926,"cache_creation":{"ephemeral_5m_input_tokens":926,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Ccjgpd4tSSVAd2f7Ez36u","attributionAgent":"general-purpose","type":"assistant","uuid":"86c2cd1b-a7b5-4645-be8d-7e9f9fb4a13d","timestamp":"2026-07-05T22:20:38.266Z","userType":"external","entrypoint":"cli","cwd":"/home/xe/Code/xeiaso.net/ircd.rs","sessionId":"f2966b3c-92d4-4c1a-bdd8-7e37aed36c69","version":"2.1.201","gitBranch":"master"}

finishing-a-development-branch\n- command-cluster-port\n- create-blogpost\n- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope.

Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init\n-

IRCv3 [client capability negotiation](../docs/rfcs/ircv3/capability-negotiation.md):\n2\t//! the `CAP` command and its subcommands.\n3\t//!\n4\t//! This module is the negotiation **mechanism** — version handling, the\n5\t//! suspend/resume of registration, and a per-connection enabled-capability set —\n6\t//! plus the one capability the framework itself honors, [`cap-notify`](CAP_NOTIFY)\n7\t//! (which governs eligibility for the server-sent `NEW`/`DEL` messages). Concrete\n8\t//! behavior-bearing capabilities (`multi-prefix`, `message-tags`, …) are out of\n9\t//! scope here and land in later slices; until one exists, leveva's advertised set\n10\t//! never changes at runtime, so no `NEW`/`DEL` is ever emitted (the\n11\t//! [`CapState::eligible_for_notify`] hook is where a future dynamic cap would gate\n12\t//! that broadcast).\n13\t//!\n14\t//! Everything here is pure (a parsed [`Message`] in, reply [`Message`]s out), so the\n15\t//! whole negotiation surface is unit-tested directly; [`crate::session`] owns one\n16\t//! [`CapState`] per connection and wires the registration suspend/resume.\n17\t\n18\tuse std::collections::BTreeSet;\n19\t\n20\tuse crate::{Message, Numeric};\n21\t\n22\t/// The `cap-notify` capability name.
