skill-prototype skillA
skill-prototype is agent-read markdown (skill) from nyldn/claude-octopus: Prototype one risky assumption within a fixed budget, then keep or discard the result.
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
mdr add nyldn/claude-octopus/skill-prototype@git:20260906.89d2d35mdr add nyldn/claude-octopus/skill-prototype@sha256:29a9d0c81bdd492dPin 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.
