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.
Testing Standards
Write tests following 3-layer pyramid (unit 95%, integration 85%, E2E critical paths) with 1:1 file mapping for unit tests. Covers test organization, coverage requirements, fixtures, and best practices. Use when writing tests, checking coverage, or validating test structure.
testing-strategy
테스트, 테스팅, QA, 테스트 전략, 품질 보증 - Use when designing test strategies, writing test plans, or ensuring quality assurance. Guides systematic testing approach from unit to E2E with proper coverage and scenario design.
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.
testing-patterns
TDD workflows, test generation, and coverage strategies with Claude Code. Use when writing tests, implementing TDD, analyzing coverage gaps, or generating quality unit/integration/e2e tests. Covers Jest, Vitest, pytest, and mocking patterns.
tdd-full-coverage
Use when implementing features or fixes - test-driven development with RED-GREEN-REFACTOR cycle and full code coverage requirement
pr-test-analyzer
Use when asked to evaluate PR test coverage or explicitly asked to run the pr-test-analyzer subagent.
testing
How to effectively test the application, always use when writing tests
code-auditor
Performs comprehensive codebase analysis covering architecture, code quality, security, performance, testing, and maintainability. Use when user wants to audit code quality, identify technical debt, find security issues, assess test coverage, or get a codebase health check.
testing-best-practices
Comprehensive testing methodologies, frameworks, and patterns. Use when writing tests, debugging test failures, improving coverage, or implementing TDD workflows.
test-generation
Use when generating tests for new or existing code to improve coverage - provides a structured workflow for analyzing code, creating tests, and validating coverage goals.
modernize
Brownfield Upgrade - Upgrade all dependencies and modernize the application while maintaining spec-driven control. Runs after Gear 6 for brownfield projects with modernize flag enabled. Updates deps, fixes breaking changes, improves test coverage, updates specs to match changes.
test-driven-development
Red-green-refactor development methodology requiring verified test coverage. Use for feature implementation, bugfixes, refactoring, or any behavior changes where tests must prove correctness.

fullstack-testing
Fullstack testing - unit, integration, E2E, coverage
testing-assistant
Activates when user needs help writing tests, understanding testing patterns, or improving test coverage. Triggers on "write tests", "add unit tests", "test this function", "improve coverage", "mock this", "testing strategy", or questions about Jest, pytest, testing frameworks.
pytest-coverage
Generate or extend pytest suites to reach at least 80% total coverage for the repository while excluding src/safe_family/templates/miscellaneous/. Use when asked to add tests, raise coverage, or set up CI coverage gates.
python-expert-tester
Expert guidance for Python testing that analyzes your existing setup and provides evidence-based recommendations. I'll examine your current tests, configurations, and dependencies before suggesting changes. Use when writing tests, improving coverage, debugging issues, or optimizing testing setup.
