## Files Accessed

| File | Purpose |
|------|---------|
| Agent file at `{agent_file_path}` | Agent persona and capabilities |
| Via `context-loading` block | Git state, gotchas, preferences |

## Error Handling

| Error | Behavior |
|-------|----------|
| Missing required parameter | Block fails with validation error |
| Agent file not found | Agent reads empty, continues with defaults |
| Invalid output_format | Default to `markdown` |

## Notes

- Template is under 20 lines of core content
- Composes with `context-loading` block for project context
- Consistent "send message to team lead" ending for orchestration
- Works with both sequential and parallel agent invocation patterns
