cold-start SKILL.md skillA
cold-start from garrytan/gbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add garrytan/gbrain/cold-start@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

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?".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade 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@sha256:eb10547b5f2fba3eThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
