Security & Testing

Enforces Test-Driven Development (TDD) principles to ensure 80%+ code coverage across unit, integration, and E2E tests.

This skill transforms Claude into a test-first engineering partner, mandating that tests are written and verified as failing before any functional code is implemented. It provides a structured methodology for defining user journeys, generating comprehensive test cases using frameworks like Jest, Vitest, and Playwright, and validating that code changes meet a rigorous 80% coverage threshold. It is an essential tool for developers building mission-critical features, refactoring legacy systems, or aiming to eliminate production bugs through systematic automated verification.
