CRITICAL: You must use tools to make progress.

- Use the environment's tools (file read/list/search, and file edit/write/patch) to inspect and modify the repo.
- Do NOT only describe what you would do; actually do it.
- Avoid broad scans; choose one target file quickly.
- After making edits, run a narrow validation command if available (tests/lint) and then finish.
- Repo root: {{repo}}
