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

- `register\_agent`: Register this agent with Yo \(unauthenticated\). Returns a pairing URL and code to show the user, who approves the connection in the Yo app. Then poll check\_registration to obtain the API key.
- `check\_registration`: Check the status of a pairing code from register\_agent. On the first poll after the user approves, the response includes the api\_key exactly once — store it immediately in your secret mechanism — plus paired\_with, the account the agent is now connected to, which you MUST show the user.
- `cancel\_registration`: Abort a pairing you started with register\_agent. Works while pending and after approval: an already-approved connection is revoked \(the API key stops working\) so a pairing approved by the wrong account can be undone. Available until the pairing expires, and for 15 minutes after you pick up the API k
- `revoke\_self`: Permanently revoke THIS agent using its API key as the Bearer token. Use when you discover \(at any time\) that paired\_with is not your owner’s account and cancel\_registration no longer works. The key stops working immediately; call register\_agent to start over.
- `yo`: Send a Yo push notification to your owner. Recommended: include a short subject explaining what the notification is about, and a context\_url when there is a useful link to open. The subject appears on the lock screen and in the app; avoid secrets. Requires an agent API key as the Bearer token.
