# Test Runner

Use this skill after implementation or before risky refactors.

## Steps

1. Inspect project files for test commands.
2. Prefer targeted tests over full suites for narrow changes.
3. Run formatting or lint checks when they directly cover the edited files.
4. Record the exact commands and results.
5. If a test cannot run, state why and what remains unverified.

## Notes

Do not invent test coverage.
Validation should match the risk of the change.
