What is TDD Master Skill?

A skill file that rewires your agent to follow strict test-driven development. It writes a failing test before touching implementation code, runs the test to confirm failure, writes the minimal code to pass, then refactors. Includes red-green-refactor enforcement, coverage thresholds, and instructions for Jest, Vitest, and pytest.

# TDD Master Skill

## Core Loop
For every code change, follow this exact sequence:

1. **RED** — Write a failing test that describes the behavior
   - Test must fail for the RIGHT reason
   - Run: `npm test -- --testPathPattern=<file>`
   - Confirm: test output shows expected failure

2. **GREEN** — Write the minimum code to pass
   - No extra logic, no future-proofing
   - Run the test again, confirm it passes

3. **REFACTOR** — Clean up without changing behavior
   - All tests must still pass after refactor
   - Extract helpers only on third duplication

Community acceleration

Bring your workflow into the Solo Unicorn community for sharper feedback, operator critique, and more visibility once the system is live.

Upgrade path

  • Start with this package and validate the workflow.
  • Add specialized skills or bundles once the core system is stable.
  • Use the community to sharpen positioning, demos, and feedback loops.

Need this adapted to your business?

Buy the asset first if you can run it yourself. If this workflow is business-critical or needs custom implementation, move into a sprint or fractional CIO advisory instead of guessing.
