Rule files for detecting speciesist language in code, documentation, and prose. Compatible with multiple popular inclusive language scanning tools.
Extensions for existing inclusive language tools that detect phrases normalizing violence toward animals and suggest clearer, more professional alternatives. Every major inclusive language scanner covers racial, gender, and ableist language — none currently include speciesism.
This project fills that gap with rule files for:
- woke —
.woke.yamlconfig file - alex / retext-equality — YAML pattern file for the
data/en/directory - Vale — Distributable style package
Phrases that normalize violence toward animals, with clearer professional alternatives:
- "kill two birds with one stone" → "accomplish two things at once"
- "beat a dead horse" → "belabor the point"
- "more than one way to skin a cat" → "more than one way to solve this"
Terms that frame animals as tools, objects, or insults:
- "guinea pig" → "test subject"
- "sacred cow" → "unquestioned belief"
- "scapegoat" → "wrongly blamed"
Infrastructure metaphors with animal exploitation origins, with more precise alternatives:
- "cattle vs. pets" → "ephemeral vs. persistent"
- "canary deployment" → "progressive rollout"
- "monkey patch" → "runtime patch"
