Excerpt

Test-Driven Development

Overview

One skill for all TDD workflows. Enforces test-first development using existing repository patterns. Three input modes handle different entry points — specs, task files, or ad-hoc descriptions — but the core cycle is always RED → GREEN → REFACTOR.

Input Modes

Detect the input type and follow the corresponding mode:

Mode A: From Spec (`.spec.md`)

Use when the input references a .spec.md file with Given/When/Then acceptance criteria.

This is the opening of the README. Read the full README on GitHub.
