What it does
Cold Start is an agent skill from inbrainfun/inbrain. 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 inbrain setup and asks "now what?"
Its SKILL.md is about 4.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Productivity & Automation, covering Email management. It works with Gmail and X (Twitter).
When your agent uses it
- A user has just finished inbrain setup and asks now what?
- Tasks that involve Email management
Example prompts
- “now what?”
- “/cold-start”
Requirements
- A credential in GOOGLE_TOKEN
Workflow steps
9 steps, taken from the step headings in SKILL.md.
- ClawVisor Setup (Required for API Access)
- Existing Markdown / Obsidian Import
- Google Contacts → People Pages
- Google Calendar (Last 90 Days)
- Gmail (Recent Threads)
- Conversation Exports (ChatGPT / Claude / Perplexity)
- X/Twitter Archive
- File Archives
- Meeting Transcripts
What it can do on your machine
Read from SKILL.md and the folder at commit 5231990. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
people.googleapis.com
Also links to:
clawvisor.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GOOGLE_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cold Start loads about 4.7k tokens when it runs. Until then it costs about 105 tokens; SKILL.md has 1,967 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,967 words (~4,688 tokens).
