Enforces a strict Red-Green-Refactor cycle to ensure code reliability and high test coverage.
This skill implements a disciplined Test-Driven Development methodology for Claude, mandating the 'Iron Law' that no production code be written without a failing test first. It guides the AI through the complete Red-Green-Refactor cycle, ensuring that tests verify behavior rather than implementation, prevents the accumulation of technical debt, and provides a structured checklist for verifying that every feature or bug fix is fully backed by a meaningful test suite.
