A single-user personal assistant.
This is a private automation that its author runs for himself. It reads his own Google Calendar and Gmail, read-only, and relays short answers to his own phone over Signal. It has no other users, no sign-up, and nothing to log in to.
It exists because a small always-on agent is more useful than a large one you have to be at a desk to talk to. Inference runs on a machine on the author's home network.
