MentorAgentAttribute class

Level 2 — Decorates a class to turn it into a specialized AI agent with a Handoff Workflow. The class must be registered in the DI container; implementing IMentorAgent is optional (discovery is by this attribute alone). MentorAgent builds a ChatClientAgent whose tools are the class's methods marked [Description] or [MentorAction], and connects it to the Handoff graph via HandoffTo.

[MentorAgent(
    Name = "OrderAgent",
    Description = "Handles everything related to orders: creation, tracking, cancellation",
    HandoffTo = ["CustomerAgent", "InvoiceAgent"]
)]
public class OrderAgent : IMentorAgent
{
    [Description("Creates a new order")]
    public async Task<Order> CreateOrder(int customerId, List<string> products) { }
}
