FlyAI Commit Lint
Enforce conventional commit messages across your team with semantic validation, scope verification, and automated fix suggestions.
When to use
Activate this skill when:
- A user runs git commit and the message does not follow conventional commit format
- A user asks to review or fix commit messages in a branch
- Pre-commit hooks need commit message validation
- CI pipelines require commit format enforcement
Commit Format
All commits must follow the pattern: type(scope): subject
Allowed Types
| Type | Description |
|---|---|
| feat | A new feature |
| fix | A bug fix |
| docs | Documentation changes |
| style | Formatting, missing semicolons, etc. |
| refactor | Code change that neither fixes a bug nor adds a feature |
| perf | Performance improvement |
| test | Adding or updating tests |
| chore | Maintenance tasks |
| ci | CI/CD configuration changes |
| build | Build system or dependency changes |
Scope Rules
- Scope is optional but recommended
- Must be lowercase kebab-case
- Should match a module, component, or directory name in the project
- Examples: auth, api, ui, database, ci
Subject Rules
- Use imperative mood: "add feature" not "added feature"
- No period at the end
- Maximum 72 characters
- Start with lowercase
Validation Process
- Parse the commit message into type, scope, subject, body, and footer
- Validate type against the allowed list
- Check scope format if present
- Verify subject follows all rules
- Check total first line length does not exceed 72 characters
- If body is present, ensure blank line separator exists
Auto-Fix Suggestions
When a commit message fails validation, suggest fixes:
- Wrong type: suggest the closest matching type
- Uppercase subject: auto-lowercase the first character
- Period at end: remove trailing period
- Past tense: suggest imperative form (added -> add, fixed -> fix)
- Missing type: infer from changed files (test files -> test, docs -> docs)
Integration
Works with:
- Git hooks (pre-commit, commit-msg)
- GitHub Actions CI checks
- Local development workflow
- Branch history cleanup before merge
Examples
Good:
- feat(auth): add OAuth2 login flow
- fix(api): handle null response from upstream
- docs: update API reference for v2 endpoints
- refactor(database): extract connection pooling logic
Bad:
- Added new feature (missing type)
- feat: Add OAuth2. (uppercase, period)
- fix(API): Fixed the bug (uppercase scope, past tense)
