cf-tdd skillA

cf-tdd is agent-read markdown (skill) from dinhanhthi/coding-friend: Use when writing new production code, adding features, implementing, or refactoring — e.g. "implement this", "build this feature", "create a function", "add a new endpoint", "write the implementation", "refactor this", "write a test", "add tests", "create a component", "implement the API", "add a route". Also auto-invoke when planning shifts to writing production code — load this first. Default: direct implementation (no new tests). TDD when `--add-tests` or config `tdd: true`. Do NOT auto-invok.

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 dinhanhthi/coding-friend/cf-tdd@git:20260827.debd979
Exact content
mdr add dinhanhthi/coding-friend/cf-tdd@sha256:ea3766fddbada18d

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.
