onboarding skillA

onboarding is agent-read markdown (skill) from huytieu/cog-second-brain: Personalize COG for your workflow - creates profile, interests, and watchlist files with guided setup (run this first!).

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/onboarding@git:20260818.622a5e5
Exact content
mdr add huytieu/cog-second-brain/onboarding@sha256:cc6b2497168b71ec

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.
