pdf-safe skillA
pdf-safe is agent-read markdown (skill) from bruc3van/agent-skills-guard: Rule matrix negative fixture - plain text file with .pdf extension marker; not intended for production deployment..
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 bruc3van/agent-skills-guard/pdf-safe@git:20260609.08d2b92mdr add bruc3van/agent-skills-guard/pdf-safe@sha256:43b1bc03fe954b03Pin 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.
