Using Agents as Tools

The agent-as-a-tool pattern involves a manager agent delegating complex, open-ended tasks to other specialist agents that function as its tools. This concept is demonstrated by building a layover travel planner using the OpenAI Agents SDK. The system features a main planner agent that calls upon specialist agents for logistics, local experiences, and risk analysis to create a robust itinerary. Each specialist agent uses its own instructions and tools, such as web search, to solve its delegated sub-task before reporting back to the manager, showcasing a practical multi-agent workflow.
