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 inkeep/open-knowledge/write-a-spec@git:20260825.3ab979amdr add inkeep/open-knowledge/write-a-spec@sha256:1e1e2fdc53351daePin 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.
