gbrain skillA
gbrain is agent-read markdown (skill) from garrytan/gbrain: Search and write the company knowledge brain. Use for any question about the org, people, projects, decisions, or history, and to persist durable knowledge beyond this scope's notebook..
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.
What the file says
# gbrain — the company brain This sandbox has the `gbrain` CLI connected (thin-client) to the org's central brain.

Your scope's own notebook stays the fast per-turn memory; the brain is where knowledge outlives a scope and becomes searchable by everyone entitled to it. ## First-run setup (once per sandbox — skip if `gbrain remote doctor` passes) Your scope's brain credentials arrive via the deployment's secret handoff (keychain entry or one-time secret drop named `gbrain`). Then: ```bash gbrain init --mcp-only \ --issuer-url "https://brain.<org>.com" \ --mcp-url "https://brain.<org>.com/mcp" \ --oauth-client-id "<client id from the handoff>" \ --oauth-client-secret "<client secret from the handoff>" gbrain whoami # must succeed before using any other command ``` Pass the secret with `--oauth-client-secret`, not via `GBRAIN_REMOTE_CLIENT_SECRET`: an env-sourced secret is deliberately NOT written to `~/.gbrain/config.json`, so every later command would fail with "No client_secret available" once the …

mdr add garrytan/gbrain/gbrain@git:20260801.aff34a4mdr add garrytan/gbrain/gbrain@sha256:c1f15bf15526d955Pin 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.
