eval-harness skillA

eval-harness is agent-read markdown (skill) from a5c-ai/babysitter: Evaluation harness for testing agent and skill quality through structured benchmarks, regression tests, and quality scoring..

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 a5c-ai/babysitter/eval-harness@git:20260601.da7723a
Exact content
mdr add a5c-ai/babysitter/eval-harness@sha256:feafb468c646322c

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.
