Git Workflow Skill

Purpose

Enforce git best practices, pre-commit hooks, and mandatory documentation updates for the career_ios_backend project.

Automatic Activation

This skill is AUTOMATICALLY activated when user mentions:

• ✅ "git commit"
• ✅ "git push"
• ✅ "ready to commit/push"
• ✅ "提交代碼"
• ✅ "推送到遠端"

---

Git Hooks Setup

First-Time Installation

# Install pre-commit and pre-push hooks
poetry run pre-commit install
poetry run pre-commit install --hook-type pre-push

Pre-Commit Checks (Fast ~5 seconds)

When you run git commit, these checks run automatically:

1. ✅ Branch Check - Prevents commits to main/master
2. ✅ Ruff Linting & Formatting - Auto-fixes code style
3. ✅ File Checks - Trailing whitespace, YAML/TOML syntax
4. ✅ Security Checks - Prevents leaking:
   • API keys
   • Secrets
   • Private keys
   • Credentials

Pre-Push Checks (Smoke Tests ~10 seconds)

When you run git push, these tests run automatically:

1. ✅ Critical Console API Smoke Tests
   • Login functionality
   • Client management core features
   • Case/Session core features
   • Full test suite (106+ tests) runs in CI

---

Commit Workflow

Step-by-Step Process

# 1. Check current branch
git branch --show-current
# ⚠️ MUST NOT be on main/master

# 2. Stage changes
git add .

# 3. Commit (triggers pre-commit hooks ~5s)
git commit -m "feat: add XXX API"
# ↓ Auto-executes:
#   ✅ Branch check
#   ✅ Ruff linting/formatting
#   ✅ Security checks
#   ✅ File checks

# 4. Push (triggers smoke tests ~10s)
git push
# ↓ Auto-executes:
#   ✅ Critical Console API smoke tests
#   ✅ Full tests run in CI (106+ tests)

Commit Message Format

Follow conventional commits:

✅ Good Examples:

• feat: add user login API
• fix: correct client code generation
• docs: update API guide
• test: add session API tests
• refactor: extract session service

❌ Bad Examples:

• update code (too vague)
• fixes (no description)
• feat: add user login API 🤖 Generated with Claude Code (no Claude signature!)

---

Manual Hook Execution (Optional)

# Run all pre-commit checks manually
poetry run pre-commit run --all-files

# Run pre-push smoke tests manually
poetry run pre-commit run --hook-stage push

# Run full integration test suite manually (106+ tests)
poetry run pytest tests/integration/ -v

---

🚨 ABSOLUTELY FORBIDDEN

NEVER Use --no-verify

# ❌ NEVER DO THIS:
git commit --no-verify
git push --no-verify

# These bypass security checks and will:
# - Allow commits to main/master
# - Skip security scans (leak secrets)
# - Skip tests (break production)
# - Violate project standards

Why it's forbidden:

• Bypasses security checks → Risk of leaking credentials
• Skips tests → Risk of breaking production
• Violates TDD → Degrades code quality
• Breaks CI/CD pipeline → Deployment failures

If Hooks Fail

DO NOT skip checks with --no-verify!

INSTEAD:

1. Read the error message
2. Fix the actual problem
3. Re-run the commit/push

Common failures and solutions:

# Failure: "Detected secrets in code"
Solution: Remove the secret, use environment variables

# Failure: "Ruff check failed"
Solution: Run `ruff check --fix app/` to auto-fix

# Failure: "Tests failed"
Solution: Fix the broken tests, don't skip them

# Failure: "On main branch"
Solution: Create/switch to feature branch

---

📚 MANDATORY Documentation Updates

CRITICAL: Before EVERY git push, you MUST update documentation.

Required Updates

# 1. Update PRD.md
- Version number (if releasing)
- New features added
- Current status

# 2. Update CHANGELOG.md
- Add changes to [Unreleased] section
- Follow Keep a Changelog format

# 3. Update CHANGELOG_zh-TW.md
- Sync with English CHANGELOG.md
- Maintain same structure

# 4. Weekly Report (if new week)
- Update progress report
- Document blockers/achievements

Enforcement

# Agent will CHECK before allowing push:
git push
  ↓
Agent checks:
  ❌ PRD.md not updated → BLOCK PUSH
  ❌ CHANGELOG.md [Unreleased] empty → BLOCK PUSH
  ❌ CHANGELOG_zh-TW.md out of sync → BLOCK PUSH
  ✅ All docs updated → ALLOW PUSH

NO EXCEPTIONS: Even small changes require documentation updates.

---

Branch Strategy

Current Branch Structure

main/master (protected)
  ↓
staging (main development)
  ↓
feature/xxx (your work)
  ↓
parents_rag_refine (current)

Branch Rules

1. NEVER commit directly to main/master

   • Pre-commit hook will BLOCK
   • Always use staging or feature branches

2. Create feature branches from staging

   git checkout staging
   git pull
   git checkout -b feature/new-feature-name
   

3. Merge back to staging when complete

   # After tests pass and code reviewed
   git checkout staging
   git merge feature/new-feature-name
   git push
   

---

Common Git Operations

Starting New Work

# 1. Update staging
git checkout staging
git pull

# 2. Create feature branch
git checkout -b feature/add-client-search

# 3. Work on feature
# ... make changes ...

# 4. Commit regularly
git add .
git commit -m "feat: add client search endpoint"

# 5. Push to remote
git push -u origin feature/add-client-search

Reviewing Before Push

# Check what will be committed
git status

# Review changes
git diff

# Review staged changes
git diff --staged

# Check recent commits
git log --oneline -5

Fixing Mistakes

# Undo last commit (keep changes)
git reset --soft HEAD~1

# Undo last commit (discard changes) ⚠️ DESTRUCTIVE
git reset --hard HEAD~1

# Amend last commit message
git commit --amend -m "new message"

# Unstage file
git restore --staged <file>

Integration with TDD Workflow

Git workflow integrates with TDD:

TDD Cycle:
  1. RED: Write failing test
  2. GREEN: Implement minimal code
  3. REFACTOR: Improve quality
     ↓
  4. GIT COMMIT ← You are here
     - Pre-commit hooks run
     - Security checks pass
     - Code formatted
     ↓
  5. GIT PUSH
     - Smoke tests run
     - Documentation verified
     - CI/CD triggered

---

Quality Gates Checklist

Before Commit

• All integration tests pass locally
• Code follows project patterns
• No hardcoded credentials
• Commit message follows format
• On correct branch (not main/master)

Before Push

• Documentation updated (PRD, CHANGELOG)
• All commits have good messages
• No sensitive data in commits
• Ready for code review
• CI/CD pipeline will pass

---

Troubleshooting

"Hook script not found"

# Reinstall hooks
poetry run pre-commit install
poetry run pre-commit install --hook-type pre-push

"Permission denied" on hooks

# Fix permissions
chmod +x .git/hooks/pre-commit
chmod +x .git/hooks/pre-push

"Pre-commit hook takes too long"

This is normal:

• Pre-commit: ~5 seconds (formatting, security)
• Pre-push: ~10 seconds (smoke tests)
• Full CI: ~2 minutes (all 106+ tests)

"I need to force push"

⚠️ Be careful with force push:

# Safe force push (recommended)
git push --force-with-lease

# Unsafe force push (avoid)
git push --force  # ⚠️ Can lose others' work

Never force push to main/master - will be rejected by remote.

---

Success Metrics

• ✅ Zero commits to main/master branch
• ✅ 100% commits pass pre-commit hooks
• ✅ All pushes have updated documentation
• ✅ No use of --no-verify flag
• ✅ All commits follow message format
