test-driven-development skillA

test-driven-development is agent-read markdown (skill) from endorphin-ai/hasbrains-agent-kit: Use when implementing any feature or bugfix, in any language or framework, before writing implementation code — write the test first, watch it fail, then write minimal code to pass. Covers the red-green-refactor loop, test-quality principles, rationalization counters, and test-layer selection..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add endorphin-ai/hasbrains-agent-kit/test-driven-development@git:20260731.4cba6d1
Exact content
mdr add endorphin-ai/hasbrains-agent-kit/test-driven-development@sha256:a7fe22aa9e69874f

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
