Commit Message Gate

Purpose

This SkillRun capsule validates a proposed Git commit message before an agent uses it. It is designed to move Conventional Commits rules out of fragile prompts and into a typed, testable preflight boundary.

SOP

  1. Accept only concise Conventional Commits subject lines.
  2. Require one of the supported types: feat, fix, docs, style, refactor, perf, test, chore, build, ci or revert.
  3. Require type: summary or type(scope): summary with exactly one space after the colon.
  4. Keep the subject at or below 70 characters.
  5. Reject multiline messages in this capsule. Longer release notes belong in a separate artifact or PR body, not the commit subject.
  6. Do not stage files automatically.

Execution Boundary

By default this capsule only validates and returns a normalized subject. If perform_commit is set to true, it may run git commit -m <message> for already staged changes only. It never runs git add ..

Required Context

  • message: proposed commit subject.
  • perform_commit: defaults to false.

Recovery Guidance

If this capsule returns PolicyViolation, rewrite the commit subject according to the llm_hint and retry. If it returns DependencyError, inspect the local Git repository state before retrying.

Prohibited Behavior

  • Do not auto-stage files.
  • Do not include multiline explanations in the commit subject.
  • Do not bypass a rejected message by calling Git directly.
