# Tdd Loop

> Drive the red-green-refactor loop for any non-trivial code change. Auto-detect the project's test runner (pytest / vitest / jest / node --test), invoke it via the tdd.py helper, and act on the normalized exit code. Use when you write a test, TDD this feature, let me test-drive a behaviour, are about to implement [feature], want to run my tests, ask is my coverage complete, or ask are tests green. Do not use for one-off exploratory scripts, throwaway spikes, or pure-documentation edits that touch no executable code.
