// Give your agent its own email address — MailKite's built-in inbox agent answers mail for you.
//
// Point a route's action at the hosted `agent`: every email to the matched address is handed to an
// inbox agent that reads it and acts on your instructions — reply, file, or escalate. No webhook
// server required.
