/**
 * This file provides an example implementation of a coordinator agent using the AI SDK.
 * Coordinator agents are responsible for routing requests to specialized agents and
 * managing the overall workflow of a multi-agent system.
 *
 * This example demonstrates basic routing logic. You can customize this to fit your specific use case.
