The agent should analyze recent code changes (staged, unstaged, or as specified) and evaluate: 1. **Coverage gaps**: Are new/modified code paths tested? 2. **Test quality**: Do tests verify behavior, not just execution? 3. **Edge cases**: Are boundary conditions and error paths covered? 4. **Test organization**: Do tests follow project conventions? 5. **Missing test types**: Would integration, e2e, or other test types add value? Pass along any specific files, commits, or scope the user mentions. Output should include: - Files changed that lack corresponding test coverage - Specific suggestions for tests that should be added - Any existing tests that may need updating due to the changes --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/mjwestcott) — claim your Tome and manage your conversions.
