Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`list_handwritten_cards`read-only	List available Handwrytten card designs and handwriting styles for privacy-preserving fulfillment. Does not expose recipient address data.
`request_delivery_permission`destructive	After the user explicitly confirms they want the recipient contacted, ask OnceAsk to request a current delivery address/permission. Accepts either a recipientId from resolve_delivery or a person's name/email. OnceAsk searches its contacts and connected Google/Gmail-derived people, then emails the secure request when possible without revealing the recipient email or street address to the agent.
`resolve_delivery`	Preferred privacy-preserving way to send something to a person. Searches OnceAsk first and, when connected, can discover a missing person from Google Contacts or Gmail interactions. Resolves to a short-lived one-time delivery token when recipient permission and a current address exist. Does not return the street address.
`send_handwritten_card`destructive	Fulfill a handwritten card using a delivery token returned by resolve_delivery. OnceAsk sends the recipient address directly to the fulfillment provider; the agent does not receive it.

Schemas: list_tools.
