Git Commit Message Guide
Format
Every commit message MUST follow this structure:
<type>(<scope>): <subject>
[optional body]
[optional footer]
Type (required)
| Type | When to use |
|---|
| feat | New feature or capability |
| fix | Bug fix |
| docs | Documentation only |
| refactor | Code change that neither fixes nor adds |
| test | Adding or updating tests |
| chore | Build, CI, tooling changes |
Scope (required)
Scope MUST be a real module name from this project.
See references/modules.md for the full list.
If unsure of the scope, check the file paths being changed — the top-level directory is usually the correct scope.
Subject (required)
- Imperative mood: "add feature" not "added feature"
- No period at the end
- Max 72 characters total (including type and scope prefix)
- Lowercase first letter
Body (optional)
- Explain WHY, not WHAT (the diff shows what changed)
- Wrap at 72 characters
- Separate from subject with blank line
Breaking Changes
If the commit introduces a breaking change, add footer:
BREAKING CHANGE: <description of what breaks and migration path>
Examples
Good:
feat(auth): add JWT token refresh endpoint
Tokens now auto-refresh 5 minutes before expiry.
Previously users had to re-login after token expiration.
fix(parser): handle empty input without crashing
refactor(db): extract connection pooling to separate module
BREAKING CHANGE: DatabaseClient constructor no longer accepts
pool config. Use PoolConfig.create() instead.
Bad:
updated some stuff ← no type, no scope, vague
feat: Add new Feature. ← capitalized, period, missing scope
fix(misc): various fixes ← "misc" is not a real module
