How does this skill handle repeated failures?

After three failed attempts to pass a test, the skill stops the implementation and triggers an architectural review to discuss potential design flaws with the user.

Why is 'Verify RED' mandatory in this workflow?

Watching a test fail confirms that the test is actually checking the intended behavior and not passing by accident or testing the wrong thing.

What is the 'Iron Law' of the Arc TDD skill?

The Iron Law dictates that no production code can be written without a failing test first. If code is accidentally written before the test, the skill requires it to be deleted and restarted from scratch.

Can I use this skill for bug fixes?

Yes, it is highly recommended for bug fixes. The process involves writing a test that reproduces the bug, watching it fail, and then implementing the fix to make it pass.

Does Arc TDD work with existing testing frameworks?

Yes, it is designed to work with your project's existing infrastructure, such as Jest, Vitest, or other standard CLI-based testing tools.

安全与测试

Enforces a rigorous Red-Green-Refactor Test-Driven Development cycle for AI-assisted coding tasks.

Arc TDD Workflow is a specialized skill for Claude Code designed to instill engineering discipline by mandating a strict Test-Driven Development (TDD) process. It operates on the 'Iron Law' that no production code is written without a prior failing test, guiding the AI through structured cycles of writing tests, verifying failures, implementing minimal code, and refactoring. This skill is essential for developers who want to ensure their AI agents produce high-quality, verifiable code while avoiding technical debt and common rationalizations that lead to buggy implementations.
