mutation-test skillA

mutation-test is agent-read markdown (skill) from greglas75/zuvo: Mutation testing with two engines. Uses the project's NATIVE mutation runner (StrykerJS / Infection / mutmut / PIT / cargo-mutants) when one is configured — installing it on explicit consent when it is not — for a reproducible, comparable score; and an LLM-guided engine for the mutation classes native mutators cannot express: error-path removal, state mutation, async hazards, and security guard removal. Generates mutations, executes them against the relevant tests, and FIXES the tests whose gaps.

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 greglas75/zuvo/mutation-test@git:20260908.6f03233
Exact content
mdr add greglas75/zuvo/mutation-test@sha256:78215ff50578776c

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.
