Test-Driven Development (TDD)

Overview

TDD is the first rule of the superskills quality standard (written up as ENGINEERING_STANDARDS.md in the superskills install — not something to look for in your project). This skill is the Red-Green-Refactor loop that standard requires; /qa-full blocks any new public surface that arrives without the tests this loop produces.

Write the test first. Watch it fail. Write minimal code to pass.

Core principle: If you didn't watch the test fail, you don't know if it tests the right thing.

Violating the letter of the rules is violating the spirit of the rules.
