using-demo is agent-read markdown (skill) from hashgraph-online/hol-guard: Recall project context..
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.
mdr add hashgraph-online/hol-guard/using-demo@git:20260817.d7b29c2mdr add hashgraph-online/hol-guard/using-demo@sha256:dfe1bfa7caca6f08Pin 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.
