Git Commits

Commit messages and pull requests contain only what the user asked for. Never add Co-authored-by: trailers or any other agent attribution.

Cursor appends a Co-authored-by: Cursor trailer to every agent git commit, whatever the settings or rules say. The strip-cursor-coauthor commit-msg hook removes it before the commit is created, so commit normally and let the hooks run.

Committing

1. Once per checkout, make sure the commit-msg hook is installed. A plain install covers every stage listed in default_install_hook_types:

   test -x "$(git rev-parse --git-path hooks)/commit-msg" || uv run pre-commit install
   

2. Commit with git commit. Never pass --no-verify: it skips the hook that removes the trailer, along with the message checks.

3. Verify with git log -1 --format=full. If the trailer is still there, the hook did not run: install it (step 1), then git commit --amend --no-edit while the commit is unpushed.

Fallback: no hooks

If installing the hooks is not an option, build the commit with git commit-tree, which Cursor leaves alone. It skips every hook too, so run them yourself first:

uv run pre-commit run --files $(git diff --cached --name-only)
uv run pre-commit run --hook-stage commit-msg --commit-msg-filename /tmp/commit-msg
old=$(git rev-parse HEAD)
new=$(git commit-tree "$(git write-tree)" -p "$old" < /tmp/commit-msg)
git update-ref "refs/heads/$(git branch --show-current)" "$new" "$old"

Passing the old tip makes update-ref fail if the branch moved in the meantime.

Pull requests

• Never append Made with Cursor, Made with [Cursor](https://cursor.com), or similar attribution to PR titles or bodies.
• PR descriptions contain only Summary and Test plan, or what the user asked for.
• After gh pr create or gh pr edit, check gh pr view <number> --json body and remove any injected footer.
