Git Commit Trailers

When to Use This Skill

Use this skill when...	Use the alternative when...
Adding `BREAKING CHANGE:`, `Release-As:`, `Co-authored-by:`, or `Signed-off-by:` trailers	Use `git-commit-workflow` for the type/scope/subject portion of the message
Driving release-please version bumps via trailer metadata	Use `release-please-configuration` to set up the manifest and changelog rules
Parsing or programmatically adding trailers via `git interpret-trailers`	Use `github-issue-autodetect` to insert `Fixes #N` / `Closes #N` references
Auditing existing commits for missing or malformed trailer keys	Use `git-commit-push-pr` for the end-to-end commit-to-PR macro

Structured key-value metadata at the end of commit messages. Trailers drive release-please automation, attribution, and issue linking.
