## When to Use

- Creating a new Pull Request
- Writing PR titles and descriptions
- Preparing commits for review
- Using `gh pr create` command

---

## Critical Patterns

### PR Title = Conventional Commit

```
<type>(<scope>): <short description>

feat     New feature
fix      Bug fix  
docs     Documentation
refactor Code refactoring
test     Adding tests
chore    Maintenance
```

### PR Description Structure

```markdown
## Summary
- 1-3 bullet points explaining WHAT and WHY

## Changes
- List main changes

## Testing
- [ ] Tests added/updated
- [ ] Manual testing done

Closes #123
```

### Atomic Commits

```bash
# Good: One thing per commit
git commit -m "feat(user): add User model"
git commit -m "feat(user): add UserService"
git commit -m "test(user): add UserService tests"

# Bad: Everything in one commit
git commit -m "add user feature"
```

---

## Code Examples

### Basic PR Creation

```bash
gh pr create \
  --title "feat(auth): add OAuth2 login" \
  --body "## Summary
- Add Google OAuth2 authentication

## Changes
- Added AuthProvider component
- Created useAuth hook

Closes #42"
```

### PR with HEREDOC (Complex Description)

```bash
gh pr create --title "feat(dashboard): add analytics" --body "$(cat <<'EOF'
## Summary
- Add real-time analytics dashboard

## Changes

## Testing

- [x] Manual testing complete

![Dashboard](url)

Closes #123
EOF
)"
```

### Draft PR

```bash
gh pr create --draft \
  --title "wip: refactor auth" \
  --body "Work in progress"
```

### PR with Reviewers and Labels

```bash
gh pr create \
  --title "feat(api): add rate limiting" \
  --body "Adds rate limiting to API" \
  --reviewer "user1,user2" \
  --label "enhancement,api"
```

---

## Commands

```bash
# Create PR
gh pr create --title "type(scope): desc" --body "..."

# Create with web editor
gh pr create --web

# View PR status
gh pr status

# View diff
gh pr diff

# Check CI status
gh pr checks

# Merge with squash
gh pr merge --squash

# Add reviewer
gh pr edit --add-reviewer username
```

---

## Anti-Patterns

### Don't: Vague Titles

```bash
# Bad
gh pr create --title "fix bug"
gh pr create --title "update"

# Good
gh pr create --title "fix(auth): prevent session timeout"
```

### Don't: Giant PRs

```bash
# Bad: 50 files, 2000+ lines in one PR

# Good: Split into logical PRs
# PR 1: feat(models): add User model
# PR 2: feat(api): add user endpoints
# PR 3: feat(ui): add user pages
```

### Don't: Empty Descriptions

```bash
# Bad
--body "Added feature"

# Good
--body "## Summary
- What you did and why

## Changes  
- Specific changes

Closes #123"
```
