Testing

Structured guide for code reviews in two stages: specification compliance verification, then code quality assessment with detailed checklists.

Testing

Enforces the TDD cycle: write a failing test (red), implement minimal code to pass (green), then refactor while keeping tests green. Best for any testable code change, especially in projects using Vitest.

Testing

Orchestrator to test thinking token capture across 4-layer architecture. Calls prediction and attribution skills to validate multi-level integration and reasoning flow.

Testing

QA Lead specialist in test automation that creates test suites one file at a time to prevent crashes. Handles test plans, test cases, testing strategies, and quality gates. Activates for unit, integration, E2E tests (Playwright, Jest, Cypress) and test-driven/behavior-driven development (TDD/BDD). Useful when building or extending test suites with 80%+ coverage target on critical paths.

Testing

CLI tool for testing and comparing LLM outputs. Create evaluation configs, test cases, and custom assertions for validating model behavior.

Testing

Provides comprehensive testing strategies for iOS and Android mobile apps including unit, UI, integration, and performance tests. Automates testing with Detox for React Native, XCTest for native iOS, and Appium for cross-platform scenarios. Helps ensure code quality, catch regressions, and validate user flows before release.

Testing

Verifies test quality, coverage, and correctness by ensuring BDD scenarios map 1:1 to tests and that testing rules (≥80% coverage, error handling) are followed. Used during the review phase to confirm the implementation meets acceptance criteria through automated test validation.

Testing

Expert visual validation specialist for UI testing, design system compliance, and accessibility verification. Masters screenshot analysis, visual regression testing, and component validation.

Testing

Master Checkstyle built-in checks for Java including naming conventions, code metrics, and suppressions.

Testing

Enforces a TDD/BDD testing strategy using describe/it syntax, requiring tests to be written before code and coverage ≥80%. Helps maintain code reliability and catch regressions by running tests locally before every commit.
