Can I use this skill with any programming language?

Yes, the TDD Workflow skill is language-agnostic and works with any testing framework you have configured in your local environment.

Does this skill handle the refactoring step automatically?

The skill prompts and guides the refactoring phase after a test passes, ensuring that the code remains clean without breaking existing functionality.

How does the TDD Workflow skill improve code quality?

By enforcing a test-first approach, it ensures that all code is written to satisfy specific requirements and prevents the introduction of untested logic or over-engineered solutions.

Why does the skill prevent writing entire test files at once?

Writing tests incrementally ensures that each test is meaningful and that the implementation code remains as simple as possible, which is a core requirement of true TDD.

Is this skill suitable for legacy codebases?

Absolutely. It is an excellent way to safely add new features or modify existing ones in a legacy system by establishing a safety net of tests first.

セキュリティとテスト

Implements a strict Red-Green-Refactor cycle for disciplined Test-Driven Development within Claude Code.

概要

The TDD Workflow skill transforms Claude into a disciplined pair programmer by enforcing the core tenets of Test-Driven Development. It guides the AI to write only the simplest possible test for a single piece of functionality, verify the failure, and then implement the minimal amount of code necessary to pass. This incremental approach prevents over-engineering and ensures that every line of production code is backed by a verified test, resulting in more robust, maintainable, and bug-free software architectures.

主な機能

Verifies test failures before allowing implementation code
13 GitHub stars
Prevents the common AI error of writing oversized test files upfront
Restricts implementation to one discrete feature at a time
Enforces the classic Red-Green-Refactor development cycle
Automates iterative testing during the refactoring phase

ユースケース

Refactoring complex logic while ensuring zero regressions
Implementing bug fixes by first reproducing them with a failing test
Building new features from scratch with 100% test coverage
