## Arguments

| Arg | Default | Description |
|-----|---------|-------------|
| `--against` | origin/main | Target branch |
| `--lang` | system | PR content language |
| `--prefix` | "" | Prefix to prepend to title |

## Workflow

1. Run `${CLAUDE_PLUGIN_ROOT}/skills/collect-pr-info/scripts/collect-info.sh -a <target> --lang <lang>`
2. Check for errors
3. Read temp files (commits, diffs)
4. Draft PR title and body
5. Prepare preceding PR update (if exists)
6. Run `${CLAUDE_PLUGIN_ROOT}/skills/collect-pr-info/scripts/cleanup.sh <temp_dir>`
7. Return complete PR data

## Output JSON

```json
{
  "current_branch": "feature/x",
  "target_branch": "origin/main",
  "push_needed": true,
  "matched_spec": "auth",
  "pr": {
    "title": "feat(auth): add login module",
    "body": "## Summary\n..."
  },
  "existing_pr": {
    "exists": false,
    "number": null
  },
  "preceding_pr": {
    "exists": true,
    "number": 122,
    "updated_body": "## PR Order\n- this PR\n- #NEW\n\n<original body>"
  }
}
```

Agent replaces `#NEW` with actual PR number after creation.
