The Test Writer skill automates the rigorous process of quality assurance by analyzing your code to identify inputs, outputs, and invariants. It generates a detailed test matrix that covers the happy path, edge cases, and potential failure modes, then provides implementation sketches for unit and integration tests. Beyond basic testing, it incorporates advanced patterns like property-based fuzzing, performance probes, and observability assertions, ensuring your code is deterministic, parallel-safe, and production-ready.
