Documentation

README

Happier Testing And TDD

Use this skill for behavior-changing work in this repository, especially when changes touch shared runtime contracts, CLI/server/UI flows, or any lane that historically accumulates stale fixtures.

Goal

Apply strict RED-GREEN-REFACTOR while following Happier-specific lane, fixture, and rerun rules so changes do not silently drift until a late pipeline sweep.

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