Quick Reference

Commit Types

Type	Use Case
feat	New feature for user
fix	Bug fix for user
docs	Documentation only
style	Formatting, no logic change
refactor	Code change, no feature/fix
perf	Performance improvement
test	Adding/correcting tests
build	Build system/dependencies
ci	CI configuration
chore	Other non-src/test changes

Subject Line Rules

• Format: <type>(<scope>): <subject>
• Max 50 characters
• Imperative mood: "add" not "adds" or "added"
• No period at end
• Lowercase after type prefix

Body Guidelines

• Explain WHY, not just WHAT
• Wrap at 72 characters
• Include context for future developers

Quality Checklist

Before finalizing commit message:

• Type matches change purpose
• Scope reflects affected area
• Subject under 50 chars, imperative
• Body explains motivation/rationale
• Breaking changes marked with BREAKING CHANGE:
• Issues referenced (Fixes #123, Refs #456)
• Co-authors attributed
• Atomic: single logical change

Standard Footer

All commits include:

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Co-Authored-By: Claude <noreply@anthropic.com>

Red Flags

NEVER produce:

• Vague subjects ("fix bug", "update code")
• Missing context for WHY
• Multiple unrelated changes in one commit
• WIP or temporary commits
• Breaking changes without BREAKING CHANGE note

Integration Points

• Works with session-chronicler for session summaries
• Feeds into changelog-generator for releases
• References validation-agent test results
• Follows documentation-standards skill guidelines

Workflow

1. Analyze: Use ultrathink to understand change purpose
2. Categorize: Determine type and scope
3. Draft: Write subject, then body
4. Validate: Run through quality checklist
5. Format: Apply standard footer
