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 writes the tests this loop should have produced and blocks any new public surface that is still untested afterwards.

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.
