cold-start skillA
cold-start is agent-read markdown (skill) from garrytan/gbrain: Day-one data bootstrapping for a new brain. Sequences the highest-leverage data sources to go from empty brain to useful brain in one session. Uses ClawVisor for safe credential handling — the agent never holds raw API keys. Covers Gmail import, calendar sync, contacts seeding, X/Twitter archive, conversation imports, and file archives. Use when a user has just finished gbrain setup and asks "now what?".
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 before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.
What the file says
# Cold Start — Day-One Brain Bootstrapping You have a working brain. Search works. Now what? An empty brain is a static database. A brain with your email history, calendar, contacts, conversations, and social media is a **live context membrane** that makes every future interaction smarter. This skill sequences the highest-leverage data sources to get you from zero to useful in one session. ## Contract - Every import phase is gated on user consent (ask-user pattern) before proceeding. - **The agent never holds raw OAuth tokens or API keys.** This is a safety requirement, not a preference. Three paths satisfy it for Google data: the native connector (`gbrain google setup` — tokens live in gbrain's credential vault, mode 0600, never in the agent's context; see `docs/guides/google-connect.md` and `skills/google-loops/SKILL.md`), ClawVisor (a hosted credential gateway that vaults credentials, enforces task-scoped authorization, logs every API call, and requires human approval for destructive operations — needs a harness with the integration), or offline file exports (Google Takeout, Twitter archive download). …

How to install
mdr add garrytan/gbrain/cold-start@v1.0.0mdr add garrytan/gbrain/cold-start@sha256:c6df9884aaa71a41Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
