## Extracting Issue ID from Branch Name

| Branch Name | Extracted ID | Tracker |
|-------------|--------------|---------|
| `feat/PROJ-123-add-login` | `PROJ-123` | JIRA |
| `fix/123-bug-fix` | `#123` | GitHub |
| `feature/ENG-456-new-feature` | `ENG-456` | Linear |
| `bugfix/STUDIO-789-fix-issue` | `STUDIO-789` | JIRA |
| `chore/sc-12345-cleanup` | `sc-12345` | Shortcut |

## Resolution Priority

1. **Explicit argument**: `/pr-all-in-one main PROJ-123`
2. **Branch name extraction**: Uses configured `issuePattern`
3. **N/A**: If not found, no issue linking

## Custom Patterns

For custom issue trackers, define in `pr-config.json`:

```json
{
  "issueTracker": "custom",
  "issuePattern": "CUSTOM-[0-9]+",
  "issueUrlTemplate": "https://tracker.example.com/issues/{id}"
}
```
