test-driven-dev skillA

test-driven-dev is agent-read markdown (skill) from zebbern/claude-code-guide: Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development..

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 zebbern/claude-code-guide/test-driven-dev@git:20260531.164971d
Exact content
mdr add zebbern/claude-code-guide/test-driven-dev@sha256:ee6b8b1f77ee8e14

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.
