test-gap-analysis skillA

test-gap-analysis is agent-read markdown (skill) from dotnet/skills: Pseudo-mutation analysis ONLY: answer whether tests would catch a bug if production code changed, which meaningful changes would still pass, or which caller-visible mutations existing assertions would miss; verify candidates when requested, then optionally close verified gaps. Activate for behavioral blind spots or missing edge cases tied to production behavior. Polyglot. DO NOT USE FOR: suite organization, taxonomy, metadata, or distribution reports (test-tagging); .NET line-vs-branch or Cobert.

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/test-gap-analysis@git:20260904.ac8f412
Exact content
mdr add dotnet/skills/test-gap-analysis@sha256:f440af358dc09d07

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.
