create-custom-grader skillA

create-custom-grader is agent-read markdown (skill) from nvidia/skillevaluator: Use when converting an existing benchmark, rubric, verifier, task YAML/JSON, or domain check into SkillEvaluator BYOG/BYOT custom evaluation..

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 nvidia/skillevaluator/create-custom-grader@git:20260805.fe1ea34
Exact content
mdr add nvidia/skillevaluator/create-custom-grader@sha256:3fa1e016b4ea3fd7

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.
