proposal: inclusive language rules for speciesist terminology

[stuckvgn]

Proposal

Add inclusive language rules to Ruff that detect speciesist terminology in comments, docstrings, and string literals, suggesting clearer alternatives.

Context

Ruff already covers code style, security, complexity, and typing. Inclusive language scanning is a natural extension — several other linting tools have added this category:

• ESLint: eslint-plugin-speciesism
• proselint: PR #1483 — merged speciesism checks alongside existing sexism/LGBTQ+ checks
• woke: PR #284
• alex/retext-equality: PR #130

Example Rules

Code	Rule	Fix
# Kill two birds with one stone	SPE001	# Accomplish two things at once
# This is a guinea pig feature	SPE002	# This is a test feature
# Treat servers like cattle, not pets	SPE003	# Treat servers as ephemeral, not persistent
CANARY_DEPLOYMENT = True	SPE004	PROGRESSIVE_ROLLOUT = True

Severity

These would be suggestion-level rules, disabled by default, opt-in via configuration. Similar to how Ruff handles style preferences — available for teams that want them, invisible to those who don't.

Willingness to Contribute

Happy to implement if there's interest. Open Paws has already built speciesist language detection for 7+ tools.

Thank you for your request.

several other linting tools have added this category:

* ESLint: [eslint-plugin-speciesism](https://github.com/Open-Paws/eslint-plugin-speciesism?rgh-link-date=2026-02-25T13%3A40%3A02.000Z)

* proselint: [PR #1483](https://github.com/amperser/proselint/pull/1483) — merged speciesism checks alongside existing sexism/LGBTQ+ checks

* woke: [PR #284](https://github.com/get-woke/woke/pull/284)

* alex/retext-equality: [PR #130](https://github.com/retextjs/retext-equality/pull/130)

This is not a comment against or in favor of adding such rules, but it does not help your argumentation if you make false claims. The first link goes to a plugin authored by your organization. And the other three links point to pull requests that have not been merged (and haven't even seen any maintainer attention).

@sharkdp — you're right, and thank you for calling this out.

To correct the record:

1. The ESLint plugin is ours. eslint-plugin-speciesism is an Open Paws project. Listing it alongside other tools without making that clear was misleading — it's not independent ecosystem adoption, it's our own work.

2. None of those PRs have been merged. The proselint, woke, and retext-equality PRs are all still open with no maintainer engagement. The issue text saying proselint "merged speciesism checks" is flat-out wrong. They're proposals, not accepted additions.

I should have been precise about this. Overstating the case undermines the actual argument, and I appreciate you holding it to a higher standard.

The proposal itself doesn't depend on those claims though. The core case is:

• Ruff is the dominant Python linter and already handles style/complexity/security
• Inclusive language linting exists as a category (alex, woke, proselint all have frameworks for it)
• Speciesist idioms in code carry the same kind of normalizing weight that other inclusive language tools address
• These would be opt-in, suggestion-level, disabled by default — zero impact on anyone who doesn't want them

Happy to edit the issue description to correct the inaccuracies if that's useful.
