SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents you from shipping unverified code by enforcing a test-first workflow before implementation, reducing regressions and making behavior changes safer.

Core Features & Use Cases

Red-Green-Refactor Workflow: Write a failing test, implement the smallest possible fix, then clean up without changing behavior.
Bug Fix Verification: Reproduce defects with a test first so every fix is proven and protected against future regressions.
Refactoring Guardrails: Change code confidently while keeping coverage on real behavior instead of relying on after-the-fact checks.
Use Case: When adding a retry mechanism, the Skill guides you to define the expected behavior in a test, watch it fail, implement the minimal logic, and confirm the suite stays green.

Quick Start

Use this Skill to help me write a failing test for the feature I want to build and then implement only enough code to make it pass.

FAQPage Schema

How do I fix a bug using test-driven development?▼

Test-driven development guides you to write a failing test first, implement the minimal logic to make it pass, and then clean up the code. This enforces a test-first workflow that reduces regressions and makes behavior changes safer.

How does the red-green-refactor workflow work for unit tests?▼

The red-green-refactor workflow involves writing a failing unit test, implementing the smallest possible code fix to turn it green, and then cleaning up without changing behavior. This ensures real-behavior tests and minimal code changes.

Can I use test-first development when refactoring existing code?▼

Yes, you can use test-first development when refactoring existing code. It provides refactoring guardrails by keeping coverage on real behavior, allowing you to change code confidently rather than relying on after-the-fact checks.

What is the best way to add a new feature without shipping unverified code?▼

The best way to add a feature without shipping unverified code is to define the expected behavior in a test, watch it fail, implement only enough logic to pass, and confirm the test suite stays green throughout the process.

When do I need to write a failing test before implementation code?▼

You need to write a failing test before implementation code when adding new features, fixing bugs, refactoring, or changing software behavior. This test-first approach prevents shipping unverified code and reduces regressions.
