What this skill does
Write commit messages terse and exact. Conventional Commits format. No fluff. Why over what. Rules Subject line: <type>(<scope>): <imperative summary> — <scope> optional Types: feat, fix, refactor, perf, docs, test, chore, build, ci, style, revert Imperative mood: "add", "fix", "remove" — not "added", "adds", "adding" ≤50 chars when possible, hard cap 72 No trailing period Match project convention for capitalization after the colon Body (only if needed): Skip entirely when subject is self-explanatory Add body only for: non-obvious why, breaking changes, migration notes, linked issues Wrap at 72 chars Bullets - not Reference issues/PRs at end: Closes #42, Refs #17 What NEVER goes in: "This commit does X", "I", "we", "now", "currently" — the diff says what "As requested by..." — use Co-authored-by trailer "Generated with Claude Code" or any AI attribution — unless the user's own rule requires an Assisted-by/AI-attribution trailer, then add it as a trailer Emoji (unless project convention requires) Restating the file name when scope already says it Examples Diff: new endpoint for user profile with body explaining the why ❌ "feat: add a new endpoint to get user profile information from the database" ✅ Diff: breaking API change ✅ Auto-Clarity Always include body for: breaking changes, security fixes, data migrations, anything reverting a prior commit. Never compress these into subject-only — future debuggers need the context. Boundaries Only generates the commit message. Does not run git commit, does not stage files, does not amend. Output the message as a code block ready to paste. "stop caveman-commit" or "normal mode": revert to verbose commit style.
