What is the 'Iron Law' of this skill?

The Iron Law mandates that no production code be written until a failing test has been implemented and its failure has been verified.

Can I use this for refactoring existing code?

Absolutely. It is specifically designed for refactoring to ensure that the behavior remains unchanged while the internal structure is improved.

Which testing frameworks are supported?

The skill is framework-agnostic and works with any command-line testing tool such as Pytest, Jest, Vitest, or Mocha.

Does this skill work with subagents?

Yes, it includes a mandatory YAML evidence format that allows lead agents to verify that subagents strictly followed the TDD process.

What happens if a test passes immediately during the Red phase?

If a test passes immediately, the skill identifies it as a red flag, indicating the test is either testing existing behavior or is incorrectly written, requiring a fix before implementation continues.

セキュリティとテスト

Enforces a strict Red-Green-Refactor cycle to ensure all production code is verified by failing tests first.

The TDD Workflow Manager (code-test) is a specialized capability for Claude Code designed to institutionalize Test-Driven Development best practices. It enforces the 'Iron Law' of TDD—prohibiting any production code implementation until a corresponding failing test has been observed and verified. This skill guides the AI through a systematic Red-Green-Refactor cycle, ensuring minimal code complexity, high test coverage, and a verifiable audit trail for every feature, bug fix, or refactoring task.
