What it does
Long-form description, mapped skills, and a concrete usage example.
The pizza seller agent is the LangGraph-backed remote seller in the food-ordering demo. It highlights how a specialized seller agent with a different framework can still interoperate cleanly with the same purchasing concierge over A2A.
Take pizza orders
Handle pizza menu questions and order requests over A2A.
Interoperate with a concierge agent
Accept delegated ordering requests from a root purchasing agent.
Example conversation
Input from concierge: "Order one BBQ chicken pizza." Output: the seller accepts the request and returns an order response to the concierge.
