What TDD Workflow does

TDD Workflow enforces red-green-refactor development with tests written before implementation. Use it for new features, bug fixes, and refactors when you want behavior verified by failing tests first.

TDD Workflow is cataloged under Quality on DirSkills. TDD Workflow comes from a repository tagged ai, anthropic-claude, claude, claude-ai and claude-code.

Documentation

README

TDD Workflow

Strict Red-Green-Refactor discipline for every code change. Tests come first — no exceptions.

Overview

This skill enforces TDD as a non-negotiable workflow:

  1. RED — Write a failing test that describes the desired behavior
  2. GREEN — Write the minimum code to make it pass
  3. REFACTOR — Clean up with all tests green

Never write implementation before a test exists for the happy path.

When to Use

  • Implementing any new feature or function
  • Fixing a bug (write the regression test first)
  • Refactoring existing code (ensure tests exist first)
  • Adding edge case handling

RED Phase: Write the Failing Test

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