tropius#

tropius is a CLI to detect AI tropes in prose.

How#

We use a pattern dictionary in TOML based on a trope list from Tropes.fyi

Text
  ↓
Aho-Corasick phrase matcher
  ↓
Structural, repetition, and character-class detectors
  ↓
Findings report

Usage#

Scan text from stdin:

printf 'Let us delve into this robust ecosystem.' | cargo run -q -p tropius-cli

Scan article text extracted from a live URL with lectito:

# Install lectito
cargo install lectito-cli

lectito 'https://www.solo.io/blog/what-is-agent-identity-human-workload-a-new-layer' \
    --format text \
    | cargo run -q -p tropius-cli

The CLI exits 0 when no findings are found and 1 when it finds trope signals.

It exits 2 for usage or configuration errors.

Color output respects NO_COLOR.

Coverage#

an implementation path for every source section in tropes.md
phrase patterns for literal trope signals
structural detectors for sentence and paragraph shape
repetition detectors for repeated metaphor terms and duplicated content
markdown-aware detection for bold-first bullets
character-class detection for Unicode decoration

“Claudesmell” labeller for standard.site records wen

what does claudesmell mean here

Samuel - @samuel.fm 2026-06-25 04:22

smells of claude, e.g. short, punchy yet needlessly florid prose, excessive claudeisms, it’s not just x it’s y etc

You know that feeling of nerd-sniping about to happen? I gotta use aho-corasick + tropes.fyi in some way
