update-cog skillA

update-cog is agent-read markdown (skill) from huytieu/cog-second-brain: Check for and apply upstream COG framework updates (skills, docs, scripts) without touching personal content.

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/update-cog@git:20260818.cb4644d
Exact content
mdr add huytieu/cog-second-brain/update-cog@sha256:cb59b961c7e6b5df

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.
