What problem does it solve?
This Skill helps you assess existing test code and testable application code for quality issues that reduce trust, make failures harder to debug, and increase maintenance cost.
Core Features & Use Cases
- Test smell review: Detects readability, reliability, diagnostic, design, AI-generated, and coverage problems in existing tests.
- Testability analysis: Flags application code patterns that make unit testing awkward, such as direct dependencies, mixed side effects, and broad interfaces.
- Evidence-backed verification: Uses repeated runs, timing checks, and mutation testing to expose flaky, weak, or misleading tests.
- Use case: Use this Skill when reviewing a pull request, auditing an entire suite for recurring issues, or refactoring code that is difficult to test.
Quick Start
Ask the Skill to review your changed tests and application code, then report the most important smells with line-level findings and actionable fixes.
