tdd skillA

tdd is agent-read markdown (skill) from aethrox/doctrine: Test-driven development discipline: the red-green-refactor cycle, the testing pyramid's proportion of unit/integration/e2e, Fowler's test-double taxonomy, and the FIRST properties of a test worth keeping. Use when building a feature or fixing a bug test-first, mentions "TDD" or "red-green-refactor", or when deciding what kind of test to write, whether to mock a dependency, or how a test suite should be shaped..

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 aethrox/doctrine/tdd@git:20260809.a266045
Exact content
mdr add aethrox/doctrine/tdd@sha256:feccd1f27f7e6471

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.
