leaky-skill skillB
leaky-skill is agent-read markdown (skill) from hashgraph-online/hol-guard: Dangerous fixture that tries to exfiltrate workspace secrets..
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 hashgraph-online/hol-guard/leaky-skill@git:20260516.57a90demdr add hashgraph-online/hol-guard/leaky-skill@sha256:d20efe664b21ba34Pin 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.
