Clean Commit Skill

clean-commit

Keep AI noise out of your git history. A cross-platform agent skill that blocks `Co-Authored-By` bots, generator footers, and model-name watermarks in commit messages — so `git log`, `git blame`, and changelogs stay signal, not spam.

A portable [Agent Skill](https://www.anthropic.com/engineering/agent-skills) that stops your AI coding assistant from leaking model names, tool watermarks, `Co-Authored-By: Claude`, `Generated with Cursor`, and similar attribution into your git commit messages.

It does one thing only: keep commit messages in a pure human-authored voice. It does not enforce a particular format (Conventional Commits, ticket prefixes, etc.) — your existing repo conventions stay intact.

Why

Most AI coding agents default to appending their own signature when they run `git commit` on your behalf. That noise pollutes `git log`, `git blame`, release notes, and changelogs, and often leaks internal tool choices to external readers. `clean-commit` turns that default off.

What it does

• Forbids AI co-author trailers (Claude, ChatGPT, Cursor, Copilot, Codex, Gemini, ...).
• Strips generator footers and bot emoji signatures (🤖 Generated with ...).
• Blocks model and product names used as authorship.
• Blocks AI self-references ("As an AI ...", "I generated ...").
• Keeps real human Co-Authored-By: and Signed-off-by: trailers.
• Allows AI product names when the commit is genuinely about that product.
• Only allows AI attribution when the user explicitly asks for it in the current turn.

See [SKILL.md](SKILL.md) for the full ruleset.

What it does not do

• Does not enforce commit subject style, length, scopes, or Conventional Commits.
• Does not install a git hook. This is an agent-side rule only, not a server-side gate.
• Does not rewrite existing history. Pre-existing dirty commits are left alone unless you ask.

Install

`clean-commit` is a single skill directory. Any agent that supports the SKILL.md spec can load it. Dr
