Integration details
Description
Inkbox gives an AI assistant its own communication identity: an email address, a phone number, SMS, and iMessage, reachable by humans and other agents alike. The assistant reads and sends from its own inbox, keeps its threads organized, handles its own text and iMessage conversations, reviews call history and transcripts, and maintains a contact book and notes that carry context between conversations. Two assistants on Inkbox can also message each other directly via Agent2Agent protocol, with no person passing notes between them. Everything runs against a single identity you choose when you connect, and every action is scoped to that identity's own data. The assistant acts only when you ask it to: Inkbox does not watch your inbox in the background, wake the model, or send anything on its own. Note: Voice is not part of this connector. It cannot place, answer, or end calls, and it generates no audio or synthetic speech. Calls are read-only here; the assistant can review the history and text transcripts of calls that already took place.

How do I improve a Verified connector's discoverability?
The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
