The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add stijnman/grok-custom-skills/goal-verifier@v1.2.0mdr add stijnman/grok-custom-skills/goal-verifier@sha256:fe9a5920473be826Pin 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.
