briefing skillA
briefing is agent-read markdown (skill) from garrytan/gbrain: Compile daily briefing with meeting context, active deals, and citation tracking.
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.

Use this to prioritize which meetings/deals/people get the most briefing depth. …
