test-driven-development skillA

test-driven-development is agent-read markdown (skill) from flieber-inc/devcake: Strict red-green-refactor discipline at public seams — write a failing test, watch it fail, write minimal code to pass. Use when implementing features, bug fixes with a known reproduction, or new modules, before production code. Prefer port/fakes over private-helper tests. Companion: verification-before-completion for proof after green; systematic-debugging when the failure’s cause is unclear..

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 flieber-inc/devcake/test-driven-development@git:20260720.fa58fb9
Exact content
mdr add flieber-inc/devcake/test-driven-development@sha256:b92bf198f578c9ec

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.
