How does it handle the refactoring phase?

It guides the user to improve code structure and style without changing behavior, running the test suite after every change to ensure the code remains 'Green'.

What languages does the TDD Cycling skill support?

The skill includes built-in support for Python (pytest), JavaScript (Jest), and Go, and it can detect common project conventions for each.

Can I use this for existing projects?

Yes, it automatically scans your project root for existing test directories like /tests, /spec, or /__tests__ to integrate with your current setup.

Does it allow writing code before tests?

No, the skill strictly enforces TDD principles, requiring a failing test to be verified before any production code can be written.

安全与测试

Enforces a strict Red-Green-Refactor development workflow to ensure high test coverage and clean code architecture.

The TDD Cycle Enforcer is a specialized Claude Code skill designed to automate and guide the Test-Driven Development (TDD) process. It provides a structured framework for the Red-Green-Refactor cycle, ensuring that no production code is written without a corresponding failing test. The skill intelligently detects project structures for languages like Python, JavaScript, and Go, identifies the correct test runners, and validates that tests fail for the right reasons before allowing implementation. By separating the 'make it work' phase from the 'make it clean' phase, it helps developers maintain high code quality, prevent regressions, and generate standardized conventional commits.
