Can I skip TDD for simple configurations or prototypes?

The workflow permits exceptions for throwaway prototypes, generated code, and configuration files, but generally encourages TDD for all logic-bearing code to prevent technical debt.

How does the workflow handle existing code without tests?

When improving or fixing existing code, the skill requires you to first write tests for the current behavior (to catch regressions) or for the new desired behavior (to drive development) before modifying the implementation.

Does this skill require the session-management plugin?

No, it works as a standalone TDD guide. However, integrating it with session-management enables advanced features like automatic checkpoints, cycle tracking, and detailed TDD metrics in your session reports.

What is the Iron Law in this TDD workflow?

The Iron Law mandates that no production code can be written without a failing test first. If code is written prematurely, the workflow requires it to be deleted to ensure the developer only implements what is necessary to pass the test.

セキュリティとテスト

Enforces strict Test-Driven Development discipline by mandating a Red-Green-Refactor cycle for all code changes.

概要

The TDD Workflow skill transforms Claude Code into a disciplined development partner by mandating a strict Test-Driven Development cycle. It ensures that no production code is written without a preceding failing test, tracking every Red, Green, and Refactor phase through automated checkpoints. When integrated with session management, it provides deep metrics on cycle times, test coverage, and discipline adherence, helping developers maintain high code quality and architectural integrity while eliminating technical debt before it is even created.
