Git Commit Helper
Overview
Automated git workflow management for enterprise projects including Conventional Commits format, CHANGELOG generation, commit validation, and pre-commit hooks.
When to Use This Skill
- Creating properly formatted commit messages
- Generating CHANGELOG.md from commits
- Setting up pre-commit hooks
- Validating commit message format
- Managing release versioning
- Creating semantic commits
CROWN RULE: NO AI ATTRIBUTION IN COMMITS
ABSOLUTELY FORBIDDEN in git commits:
Generated with [Claude Code]
Co-Authored-By: Claude <noreply@anthropic.com>
This is NON-NEGOTIABLE:
- NO AI attribution footers in commit messages
- NO "Generated with Claude" lines
- NO "Co-Authored-By: Claude" trailers
- Commits MUST appear as human-authored only
Correct commit message format:
fix(api): improve error handling
- Fixed timeout handling in middleware
- Added error bubbling for failures
fix(api): improve error handling
- Fixed timeout handling in middleware
Generated with Claude Code
Co-Authored-By: Claude <noreply@anthropic.com>
If AI attribution accidentally added:
- STOP immediately
- Use
git commit --amend to rewrite message
- Remove ALL AI attribution lines
- Force push if already pushed (after user confirmation)
Conventional Commits Format
Structure
<type>(<scope>): <subject>
<body>
<footer>
Types
feat: New feature
fix: Bug fix
docs: Documentation changes
style: Code style (formatting, no logic change)
refactor: Code restructuring (no behavior change)
perf: Performance improvement
test: Adding/updating tests
build: Build system changes
ci: CI/CD configuration
chore: Maintenance tasks
revert: Revert previous commit
security: Security-related changes
Scopes
Customize scopes for your project. Example:
api: Public REST API (apps/api)
web-ui: Web interface (apps/web-ui)
worker: Background workers (services/*)
shared: Shared types (packages/shared)
infra: Infrastructure (infra/)
auth: Authentication/authorization
config: Configuration files
tests: Test suite
docs: Documentation
ci: CI/CD pipelines
Examples
Feature:
git commit -m "feat(api): add batch processing endpoint
- Support up to 100 items per request
- Add concurrent processing
- Return aggregated results with request IDs"
Bug Fix:
git commit -m "fix(worker): correct timeout handling
- Fix 1000ms timeout not being enforced
- Add graceful degradation on timeout
- Fixes #123"
Security:
git commit -m "security(auth): fix timing attack in key validation
- Use constant-time comparison for API keys
- Add rate limiting on auth endpoints"
