# Draft PR Creator

Creates or updates a draft pull request for the current branch.

## Usage

- `/pr` - Create draft PR for current branch (or update if one exists)
- `/pr <url>` - Update existing PR description

## Workflow

### 1. Ensure feature branch and commit

**NEVER commit to `main` unless the user explicitly requests it.**

```bash
git branch --show-current
git status
```

If on `main`, create and switch to a feature branch before doing anything else.

Branch naming follows the PR type prefix:
- `feat/` — new features
- `fix/` — bug fixes
- `refactor/` — refactoring
- `chore/` — maintenance

### 2. Gather context

```bash
git log main..HEAD --oneline
git diff main...HEAD --stat
```

### 3. Check if PR already exists

```bash
gh pr view --json number,title,body 2>/dev/null
```

### 4. Write PR description

Use the template below. Keep it concise and natural.

### 5a. If NO existing PR - Create draft PR

```bash
gh pr create --draft --title "<title>" --body "$(cat <<'EOF'
<body>
EOF
)"
```

### 5b. If PR already exists - Update description

```bash
gh pr edit --title "<title>" --body "$(cat <<'EOF'
<updated body>
EOF
)"
```

Report the PR URL to the user when done.

## PR Title Format

```
<type>: <short description>
```

Types: `feat:`, `fix:`, `refactor:`, `test:`, `chore:`, `docs:`

Rules:
- Lowercase after prefix
- Present tense imperative ("add" not "added")
- Under 70 characters

## PR Body Template

```markdown
Closes #<issue_number>

## Summary

1-2 paragraphs explaining what this does and why.

## Changes

- Highlight 1
- Highlight 2
- Highlight 3

## Testing

- [ ] `mix test` passes
- [ ] `mix format --check-formatted` passes
- [ ] `mix compile --warnings-as-errors` passes
```

Omit the `Closes #...` line if there is no source issue.

## Style

- **Fluid prose** in Summary — natural writing, not robotic
- **2-3 bullet points** in Changes — highlights only, not a file list
- **No file lists** — GitHub shows that in "Files changed"

## Pipeline

```
/dev <issue> -> /review -> /commit -> /pr -> merge
```
