+### Step2: Enhance Your Own Agent
+
+Call the capabilities of ContextGenerator and Summarizer through `EMClient`.
+
+```python
+from experiencemaker.em_client import EMClient
+
+em_client = EMClient(base_url="http://0.0.0.0:8001")
+```
+
+Assume you have a list of messages generated by an agent; you can use the summarizer to generate experiences from them.
+
+```python
+request = SummarizerRequest(
+    trajectories=[Trajectory(query=query, steps=messages, answer=messages[-1].content, done=True)],
+    workspace_id="w_1234")
+response = em_client.call_summarizer(request)
+for experience in response.experiences:
+    print(experience.model_dump_json())
+```
+
+Assume you have a query; you can use the context generator to generate a new query from the query and the related
+experiences.
+
+```python
+request = ContextGeneratorRequest(trajectory=Trajectory(query=query), retrieve_top_k=1, workspace_id="w_1234")
+response = em_client.call_context_generator(request)
+new_query = f"{response.context_msg.content}\n\nUser Question\n{query}"
+```
