Coding Standards Enforcer skill for Claude and Codex

Coding Standards Enforcer as an AI skill. It asks for The code, Language, Existing conventions and 2 more, then does the rest. Free to install in Claude or…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when a file or diff needs to match a team's naming, structure, error handling, and readability rules before review. Do not use for hunting bugs or judging architecture and performance. Related topics: coding, technical.

What it will ask you for

• The code (longer free text)
• Language (free text, e.g. "Language and version")
• Existing conventions (longer free text)
• Rules to enforce (choose any: Naming, Function size, Error handling, Comments, Dead code, Duplication, Module structure)
• Strictness (choose one: Suggest only, Fix obvious issues, Rewrite fully)

How it works

1. Infer the conventions already in use from the code and any stated guide, and write them down as the standard to hold to.
2. Check the code against each selected rule in turn, listing every violation with its location.
3. Apply the fix for each violation at the chosen strictness, leaving behaviour unchanged and flagging any change that could alter output.
4. Re-read the result to confirm the same inputs would still produce the same outputs.
5. Return the cleaned code or edit list with a count of places touched per rule and the items left alone.

What you get

The cleaned code or an edit list, then a short summary table of rules applied with counts and a note on anything deliberately left unchanged.

What it watches out for

• Imposing personal style over the conventions the codebase already follows, which makes the diff noisy and invites argument.
• Renaming public identifiers that other files depend on, breaking callers the review never saw.
• Splitting functions into tiny pieces that are harder to follow than the original block.
