writing-tests skillA

writing-tests is agent-read markdown (skill) from ahgraber/skills: Use when writing or reviewing tests in any language, or diagnosing a suite that is slow, brittle, or hard to read. Triggers: "write tests", "how should I test this", "what kind of test", "test is flaky/fragile", "should I mock this", "test is hard to read". Python-specific practices (mocking, pytest, async) are included in `references/python-testing.md`..

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 ahgraber/skills/writing-tests@git:20260819.209d97b
Exact content
mdr add ahgraber/skills/writing-tests@sha256:8bf26ec0aab3d011

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.
