Does this skill work with any testing framework?

Yes, it uses standard bash tools to run your project's specific test commands (npm test, pytest, etc.) and interprets the output.

How do I start a TDD session with Claude?

Simply use activation phrases like 'start TDD', 'use a TDD approach', or 'test-drive this' to trigger the state machine.

What is the 'Refactor' state for?

Once a test passes (Green), the skill forces an assessment of code quality, encouraging you to improve design, naming, and architecture before finishing.

What happens if I try to write code before a test?

The skill's governance will flag a state violation. It requires a 'Planning' phase and a 'Red' phase (failing test) before any production code is written.

Why does Claude prefix every message with an emoji?

The prefix (e.g., 🔴 TDD: RED) is a mandatory visual indicator to ensure the TDD lifecycle is strictly followed without skipping critical steps.

Seguridad y Pruebas

Enforces a strict test-driven development workflow using a governed Red-Green-Refactor state machine.

Acerca de

The TDD Process skill transforms Claude into a disciplined development partner by enforcing a rigorous test-driven state machine. It mandates a 'test-first' approach where implementation only begins after a meaningful test failure is established. By requiring state announcements in every message (Planning, Red, Green, Refactor, Verify), it prevents over-engineering and ensures that every line of code is justified by a requirement and verified by an automated suite. This skill is essential for developers seeking high-integrity codebases and 100% functional test coverage.

Características Principales

Mandatory state-prefixing on every message to maintain context and discipline
94 GitHub stars
