SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enforces Test-Driven Development as a discipline: write a failing test first, observe red, then implement minimal code to pass, followed by refactoring.

Core Features & Use Cases

Red-Green-Refactor workflow for features, bugs, and refactors.
Mandatory failing tests before implementation to ensure correct behavior.
Verification of test success across unit and integration tests.
Clear guidance on test naming, coverage, and avoiding mocks that test mocks.

Quick Start

Start a TDD cycle: write a failing test for the new behavior, run tests to see failure, implement minimal code to pass, then refactor.
