Does this skill work with any programming language?

Yes, as long as your environment has a test runner, compiler, or linter accessible via the terminal, the TDD Process skill can manage the workflow for any language.

How do I trigger the TDD Process skill in Claude Code?

You can activate the skill by using natural language triggers such as 'use a TDD approach', 'start TDD', or 'test-drive this feature' within your Claude Code session.

Why does Claude prefix every message with a TDD state?

Prefixing ensures absolute alignment between the AI and the developer, preventing the model from skipping the 'Planning' or 'Red' phases and jumping straight to implementation.

What happens if the state machine is violated?

The skill features a meta-governance protocol that monitors for state mismatches. If a state is skipped or evidence is missing, Claude will issue a 'STATE VIOLATION DETECTED' alert and recover to the last valid state.

Does it automatically run my tests?

Yes, the skill is designed to use Claude's bash capabilities to execute test commands, capture the output, and verify if a test has actually failed or passed as claimed.

보안 및 테스팅

Enforces a disciplined Red-Green-Refactor workflow through a rigorous state machine to ensure verifiable software quality.

소개

The TDD Process skill transforms Claude into a high-integrity engineering partner by implementing a mandatory state machine that governs the entire development lifecycle. By forcing explicit state announcements (Planning, Red, Green, Refactor, Verify) and requiring verifiable evidence via tool calls before every transition, this skill eliminates shortcuts and ensures that code is only implemented to satisfy failing tests. It is particularly effective for teams requiring high test coverage, strict architectural adherence, and bug-free deployments through continuous linting and compilation checks.
