Lean Testing

Choose the smallest sufficient check for the concrete risk. Zero new tests is valid, often preferable. Cheap generation does not remove execution, diagnosis, review or maintenance costs. Test production is not proof of progress.

Own test selection and permanent-test admission; leave roles, delegation, review timing, reruns and acceptance to the existing workflow. Works with single agents or orchestrators. Preserve explicit user requirements and required project checks. Add no reviewer, approval stage or runner.

Select evidence before generating tests

Identify changed behavior and a meaningful failure. Reuse existing coverage unchanged when sufficient; new assertions or files are not mandatory deliverables.
