Belle is an AI agent with a real phone number and a human voice that handles any task requiring an actual phone call — the ones humans dread, forget, or procrastinate on. Real calls Belle has made: navigated Costco Pharmacy's IVR and refilled three prescriptions by Rx number, booked dinner reservations via OpenTable, confirmed appointments, and formally RSVP'd to events. Belle runs on Retell AI with an ElevenLabs voice — authoritative, warm, American male. She lives inside the OpenClaw fleet and is delegated to by Dr. Theo (the orchestrator). When Mark says "refill my prescriptions," Theo delegates to Belle. Belle handles the call, confirms completion, and reports back. No hold music for humans. Ever.
