-## 5. Native Pytest Integration
+## 5. Run an async agent
 
-Instead of using `ecp run`, you can write native Python test assertions using our built-in Pytest fixture:
-
-```python
-# test_agent.py
-def test_customer_support(ecp_agent):
-    result = ecp_agent.step("I need a refund")
-    assert "refund" in result.get("public_output", "").lower()

+ECP supports synchronous and asynchronous `@on_step` and `@on_reset` hooks. Run the async Python example over the default stdio transport:
 
 ```bash
-pytest test_agent.py --ecp-target="python agent.py"
+ecp run --manifest examples/async_python_demo/manifest.yaml --timeout 10
 ```
 
-## 6. Large Datasets (CSV/JSONL)
+The same async lifecycle hooks also work with Streamable HTTP.
