Can I use this skill for refactoring existing code?

Absolutely. It is designed to help you write tests for existing functionality first, allowing you to refactor with the confidence that the behavior remains unchanged.

What testing frameworks does this skill support?

This skill provides optimized patterns and guidance for Vitest/Jest for unit and integration tests, and Playwright for end-to-end browser automation.

How does this skill handle code coverage requirements?

It enforces a minimum threshold of 80% coverage across all test types, including branches, functions, and lines, ensuring that edge cases and error paths are verified.

Does it support mocking external services?

Yes, it includes specific implementation patterns for mocking common external dependencies such as Supabase, Redis, and OpenAI to keep tests isolated and fast.

Security & Testing

Enforces test-driven development (TDD) principles to ensure high code quality and 80%+ test coverage across the full stack.

The TDD Workflow skill guides Claude Code through a strict test-first development lifecycle, ensuring that all new features, bug fixes, and refactorings are backed by comprehensive tests. It establishes high standards for software reliability by requiring a minimum of 80% coverage across unit, integration, and Playwright-based E2E tests. By automating the Red-Green-Refactor cycle and providing standardized mocking patterns for services like Supabase and Redis, this skill helps developers build resilient, maintainable, and bug-free applications.
