harness-selftest skillA

harness-selftest is agent-read markdown (skill) from broomva/skills: Fixture skill. Exists only so the eval harness has an artifact to bind its committed replay fixtures to, and so CI grades a real prompt set instead of only asserting that an empty fixture set fails. Triggered by the four cases in evals/prompts.json and by nothing else. NOT FOR any real task: it does nothing, and no agent should ever load it outside tests/skill_evals/..

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 broomva/skills/harness-selftest@git:20260728.dedf7e0
Exact content
mdr add broomva/skills/harness-selftest@sha256:2ef627dbe77a4997

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.
