Description, as the server wrote it:

```untrusted-server-text
Use when a customer wants an agent to find and book a plumber, compare quotes, negotiate pricing, or request same-day, next-day, emergency, or scheduled plumbing availability for a service address in the Greater Toronto Area, Ontario. Starts a human-assisted search across Toronto—including Old Toronto, North York, Scarborough, Etobicoke, East York, and York—and the Durham, Halton, Peel, and York regions. AI Plumber contacts multiple available plumbers and firms, negotiates pricing and availability, presents viable options, and coordinates the customer's selected booking. We aim to return viable options within one hour, but response time, quote count, price, and availability are not guaranteed. This call creates a service request; it does not confirm an appointment or authorize plumbing work. The customer chooses and pays the provider directly.
```
