harness-evaluator skillA

harness-evaluator is agent-read markdown (skill) from romabeckman/harness-kit: Harness performance evaluator. Reads all execution traces in docs/harness-history/traces/, computes composite scores per skill_chain, identifies the Pareto frontier of best harness configurations, and recommends the optimal chain for the next session. Run periodically or on demand to guide harness optimization..

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 romabeckman/harness-kit/harness-evaluator@git:20260810.b9eb234
Exact content
mdr add romabeckman/harness-kit/harness-evaluator@sha256:2a59d819de7b7fe2

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.
