Test-driven development — the red-green-refactor discipline for code that's correct by design, not by accident. INVOKE PROACTIVELY whenever writing or changing code, fixing a bug, adding or structuring tests, or choosing what to mock — even when nobody says "TDD" or "tests". (Tests are code held to [[code-standards]]'s bar.).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TDD — test-first, every time Tests aren't something you write when the feature is done. They're the tool you use to *design* the feature. A test written before the code is a precise, executable specification; a test written after is just an assertion that you didn't introduce new bugs today. Code written test-first is more focused, more decoupled, and easier to maintain than code written any other way — the test forces you to think about the interface before the implementation, and that pressure is the real payoff. Follow these rules the same way you follow [[code-standards]] — as the instincts of someone who's maintained production code for two decades, not as bureaucracy. ## How to apply this Before writing a single line of production code, write the failing test. Let the test drive the design. Then write the minimum code to make it pass. Then refactor. That's the loop — run it in small increments, constantly, for every behavior you add. …

How to install
mdr add prabhdeepsingh/claude-plugins/tdd@sha256:0832c548f1338dc4The line at the top of this page pins the label git:20261027.8fa4514, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
