+### Multi-Agent Orchestration
+
+You can use `AgentTool` to create a basic multi-agent orchestration setup.
+
+```python
+import asyncio
+
+from autogen_agentchat.agents import AssistantAgent
+from autogen_agentchat.tools import AgentTool
+from autogen_agentchat.ui import Console
+from autogen_ext.models.openai import OpenAIChatCompletionClient
+
+
+async def main() -> None:
+    model_client = OpenAIChatCompletionClient(model="gpt-4.1")
+
+    math_agent = AssistantAgent(
+        "math_expert",
+        model_client=model_client,
+        system_message="You are a math expert.",
+        description="A math expert assistant.",
+        model_client_stream=True,
+    )
+    math_agent_tool = AgentTool(math_agent, return_value_as_last_message=True)
+
+    chemistry_agent = AssistantAgent(
+        "chemistry_expert",
+        model_client=model_client,
+        system_message="You are a chemistry expert.",
+        description="A chemistry expert assistant.",
+        model_client_stream=True,
+    )
+    chemistry_agent_tool = AgentTool(chemistry_agent, return_value_as_last_message=True)
+
+    agent = AssistantAgent(
+        "assistant",
+        system_message="You are a general assistant. Use expert tools when needed.",
+        model_client=model_client,
+        model_client_stream=True,
+        tools=[math_agent_tool, chemistry_agent_tool],
+        max_tool_iterations=10,
+    )
+    await Console(agent.run_stream(task="What is the integral of x^2?"))
+    await Console(agent.run_stream(task="What is the molecular weight of water?"))
+
+
+asyncio.run(main())
