assertion-quality skillA

assertion-quality is agent-read markdown (skill) from dotnet/skills: Analyze assertion quality, depth, variety, and false confidence in existing tests. ALWAYS USE when asked about weak, shallow, trivial, always-true, self-referential, assertion-free, presence/truthiness-only, or insufficiently diverse assertions, including MSTest, Jest, pytest, and Go. DO NOT USE for direct fixes: writing-mstest-tests owns supplied MSTest assertions; code-testing-agent owns new cases. Use test-gap-analysis when asked whether tests would catch a production change, and test-anti-pa.

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 dotnet/skills/assertion-quality@git:20260903.30b30ef
Exact content
mdr add dotnet/skills/assertion-quality@sha256:4c895a35d9f9aaa0

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.
