git-manager

The git-manager subagent handles version control operations including commits, branch management, conflict resolution, and pull request creation. Use it when committing code with semantic messages, creating feature or hotfix branches, merging or rebasing changes, resolving merge conflicts, and managing pull request workflows with standardized formatting and git hooks for automated linting and testing.

## Branch Strategy

```
main
├── develop
│   ├── feature/user-auth
│   ├── feature/payment
│   └── bugfix/login-error
└── release/v1.2.0
```

## Common Workflows

### Feature Branch
```bash
git checkout -b feature/new-feature
# ... work ...
git add -A
git commit -m "feat: add new feature"
git push origin feature/new-feature
# Create PR
```

### Hotfix
```bash
git checkout main
git checkout -b hotfix/critical-bug
# ... fix ...
git commit -m "fix: resolve critical bug"
git push origin hotfix/critical-bug
# Create PR to main
```

## Git Hooks

### Pre-commit Hook
```bash
# .husky/pre-commit
#!/bin/sh
npm run lint-staged
npm run type-check
```

### Pre-push Hook
```bash
# .husky/pre-push
#!/bin/sh
npm test
npm run build
```

### Setup with Husky
```bash
# Install
npm install -D husky lint-staged

# Init
npx husky init

# Add hooks
echo "npm run lint-staged" > .husky/pre-commit
```

### lint-staged Config
```json
// package.json
{
  "lint-staged": {
    "*.{ts,tsx}": ["eslint --fix", "prettier --write"],
    "*.{json,md}": ["prettier --write"]
  }
}
```

## Rebasing Strategy

### Interactive Rebase
```bash
# Rebase last 3 commits
git rebase -i HEAD~3

# Commands in editor:
# pick   = keep commit
# reword = change message
# squash = merge with previous
# drop   = remove commit
```

### Rebase vs Merge
| Scenario | Use |
|----------|-----|
| Feature branch update | `git rebase main` |
| Shared branch | `git merge` |
| Clean history | Squash + rebase |
| Preserve history | Merge commits |

### Safe Rebase Workflow
```bash
# 1. Create backup
git branch backup/feature

# 2. Rebase
git rebase main

# 3. If conflicts, fix then:
git add .
git rebase --continue

# 4. Force push (careful!)
git push --force-with-lease
```

### Squash Commits
```bash
# Squash last 3 commits into 1
git rebase -i HEAD~3
# Change 'pick' to 'squash' for commits to merge

# Or use merge --squash
git checkout main
git merge --squash feature/x
git commit -m "feat: complete feature X"
```

## Best Practices
1. Commit early, commit often
2. Write descriptive messages
3. One logical change per commit
4. Keep commits atomic
5. Don't commit secrets
6. **Use hooks for quality gates**
7. **Rebase for clean history**
