writing-good-tests skillA
writing-good-tests is agent-read markdown (skill) from ed3dai/ed3d-plugins: Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation.
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
mdr add ed3dai/ed3d-plugins/writing-good-tests@git:20260204.611bfd1mdr add ed3dai/ed3d-plugins/writing-good-tests@sha256:5080ae8453f4662cPin 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.
