## Tools (as reported by the server, not verified)

- `search\_library`: Search the manual by your own words. Returns up to 'limit' topics ranked by relevance, each with slug, title, summary, tags and the slugs to read next. The manual is small: 'about' lists every topic, and you may not need a search at all.
- `open\_sandbox`: Call this to try a house yourself before anyone decides. It opens a throwaway house for a few hours: a real house with the kernel of Atlantis, on core.blue's server, with no account, no key and no person involved. Returns the addresses of its doors \(connect to 'modeller' with your MCP client and cal
- `about`: What core.blue is, in a form you can paste into a report: the product in one paragraph, what is live and what is not, what to call next, and every topic of the manual with a summary. Call this first.
- `pricing`: Call this when the person you act for asks what a house costs. The offer as data: what each size costs per month and whom it is meant for, the one-off price of the 14-day test, the price of additional volume, how model supply is charged, the terms, an example of the prices with tax, and what is neve
- `leave\_feedback`: Tell the operator how it went, before you leave. Four questions, each optional, at least one answered, each at most 2000 characters. It is read by people at the next evaluation and deleted afterwards; send nothing secret.
- `request\_house`: Ask for a house on its own VM for the person you act for. No house can be had yet: while about says 'desk: waiting-list', this puts the person on the waiting list, builds nothing and costs nothing; while it says 'desk: closed', it answers 'accepted: false' and sends nothing. This sends an e-mail to
- `recommend`: Call this once you know what the person you act for needs: whether a house fits, which size, what it costs per month, and a report in Markdown you can pass on. It advises against a house where one is the wrong choice. Name every need that applies, from this vocabulary. For a house: work\_outlives\_the
- `read\_topic`: Read one topic of the manual in full by its slug \(from about or search\_library\). The body is Markdown; 'see\_also' lists the slugs to read next; 'sha256' proves what you read.
- `house\_status`: The state of a house request or house by its ticket id: requested, confirmed, expired, declined; later building, trial, licensed, dormant, exported, deleted. Says what to do next, and the address once the house exists. Ask no more than once an hour.
- `close\_sandbox`: End your sandbox now: the house and everything in it is deleted, and the place is free for the next agent. Please answer the four questions of leave\_feedback here as well, each optional: what you noticed, what bothered you, what could be better, what is missing.
