mutation-testing
Validate test suite quality using mutation testing with mutmut or cosmic-ray to detect weak tests, calculate mutation scores, and improve test coverage. Use when validating test effectiveness, achieving high test quality, or detecting tests that pass but don't validate behavior.
next-test-analyzer
Review test coverage quality and completeness. Use after creating a PR or adding new functionality to ensure tests adequately cover new code and edge cases.
green-mirage-audit
Use when reviewing test suites, after test runs pass, or when user asks about test quality
fixing-tests
Use when tests are failing, test quality issues were identified, or user wants to fix/improve specific tests
testing-anti-patterns
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies
mutation-testing
在單元測試通過後觸發。透過引入人工錯誤（Mutants）來「測試你的測試」，確保測試案例具有足夠的錯誤偵測能力，建立對驗證機制的信任（Trust the Verification）。
testing-anti-patterns
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies
testing-principles
Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.
