memory-hygiene skillA

memory-hygiene is agent-read markdown (skill) from huytieu/cog-second-brain: Periodic trust sweep of persistent memory and durable knowledge notes - re-verifies environment-dependent claims against the live environment, stamps last_verified + confidence, and proposes archiving drifted entries.

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

Latest version
mdr add huytieu/cog-second-brain/memory-hygiene@git:20260807.b852369
Exact content
mdr add huytieu/cog-second-brain/memory-hygiene@sha256:093c4f588f3a8289

Pin 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.
