-            ),
-        ])
-    )],
-)
-```
-
-### Querying a RAG Agent (Streaming)
-
-```python
-openai_client = project_client.get_openai_client()
-
-stream = openai_client.responses.create(
-    stream=True, tool_choice="required", input="Your question here",
-    extra_body={"agent": {"name": agent.name, "type": "agent_reference"}},
-)
-for event in stream:
-    if event.type == "response.output_text.delta":
-        print(event.delta, end="", flush=True)
-    elif event.type == "response.output_item.done":
-        if event.item.type == "message" and event.item.content[-1].type == "output_text":
-            for ann in event.item.content[-1].annotations:
-                if ann.type == "url_citation":
-                    print(f"\nCitation: {ann.url}")
-```
-
-## Creating Agents
-
-### Basic Agent
-
-```python
-agent = project_client.agents.create_agent(
-    model=os.environ["MODEL_DEPLOYMENT_NAME"],
-    name="my-agent",
-    instructions="You are a helpful assistant.",
-)
-```
-
-### Agent with Custom Function Tools
-
-```python
-from azure.ai.agents.models import FunctionTool, ToolSet
-
-def get_weather(location: str, unit: str = "celsius") -> str:
-    """Get the current weather for a location."""
-    return f"Sunny and 22°{unit[0].upper()} in {location}"
-
-functions = FunctionTool([get_weather])
-toolset = ToolSet()
-toolset.add(functions)
-
-agent = project_client.agents.create_agent(
-    model=os.environ["MODEL_DEPLOYMENT_NAME"],
-    name="function-agent",
-    instructions="You are a helpful assistant with tool access.",
-    toolset=toolset,
-)
-```
-
-### Agent with Web Search
-
-```python
-from azure.ai.projects.models import (
-    PromptAgentDefinition, WebSearchPreviewTool, ApproximateLocation,
-)
-
-agent = project_client.agents.create_version(
-    agent_name="WebSearchAgent",
-    definition=PromptAgentDefinition(
-        model=os.environ["MODEL_DEPLOYMENT_NAME"],
-        instructions="Search the web for current information. Provide sources.",
-        tools=[
-            WebSearchPreviewTool(
-                user_location=ApproximateLocation(
-                    country="US", city="Seattle", region="Washington"
-                )
-            )
-        ],
-    ),
-)
-```
-
-> 💡 **Tip:** `WebSearchPreviewTool` requires no external resource or connection. For Bing Grounding (which requires a dedicated Bing resource and project connection), see [Bing Grounding reference](../../foundry-agent/create/references/tools/prompt-agent/tool-bing-grounding.md).
-
-### Interacting with Agents
-
-```python
-from azure.ai.agents.models import ListSortOrder
-
-thread = project_client.agents.threads.create()
-project_client.agents.messages.create(thread_id=thread.id, role="user", content="Hello")
-
-run = project_client.agents.runs.create_and_process(thread_id=thread.id, agent_id=agent.id)
-if run.status == "failed":
-    print(f"Run failed: {run.last_error}")
-
-messages = project_client.agents.messages.list(thread_id=thread.id, order=ListSortOrder.ASCENDING)
-for msg in messages:
-    if msg.text_messages:
-        print(f"{msg.role}: {msg.text_messages[-1].text.value}")
-
-project_client.agents.delete_agent(agent.id)
-```
-
-## Agent Evaluation
-
-### Single Response Evaluation (MCP)
-
-```python
-foundry_agents_query_and_evaluate(
-    agent_id="<agent-id>", query="What's the weather?",
-    endpoint="https://my-foundry.services.ai.azure.com/api/projects/my-project",
-    azure_openai_endpoint="https://my-openai.openai.azure.com",
-    azure_openai_deployment="gpt-4o",
-    evaluators="intent_resolution,task_adherence,tool_call_accuracy"
-)
-
-foundry_agents_evaluate(
-    query="What's the weather?", response="Sunny and 22°C.",
-    evaluator="intent_resolution",
-    azure_openai_endpoint="https://my-openai.openai.azure.com",
-    azure_openai_deployment="gpt-4o"
-)
-```
-
-### Batch Evaluation
-
-```python
-from azure.ai.evaluation import AIAgentConverter, IntentResolutionEvaluator, evaluate
-
-converter = AIAgentConverter(project_client)
-converter.prepare_evaluation_data(thread_ids=["t1", "t2", "t3"], filename="eval_data.jsonl")
-
-result = evaluate(
-    data="eval_data.jsonl",
-    evaluators={
-        "intent_resolution": IntentResolutionEvaluator(
-            azure_openai_endpoint=os.environ["AZURE_OPENAI_ENDPOINT"],
-            azure_openai_deployment=os.environ["AZURE_OPENAI_DEPLOYMENT"]
-        ),
-    },
-    output_path="./eval_results"
-)
-print(f"Results: {result['studio_url']}")
-```
-
-> 💡 **Tip:** Continuous evaluation requires project managed identity with **Foundry User** role and Application Insights connected to the project.
-
-## Knowledge Index Operations (MCP)
-
-```python
-foundry_knowledge_index_list(endpoint="<project-endpoint>")
-foundry_knowledge_index_schema(endpoint="<project-endpoint>", index="my-index")
-```
-
-## Best Practices
-
-1. **Never hardcode credentials** — use environment variables and `python-dotenv`
-2. **Check `run.status`** and handle `HttpResponseError` exceptions
-3. **Reuse `AIProjectClient`** instances — don't create new ones per request
-4. **Use type hints** in custom functions for better tool integration
-5. **Use context managers** for agent cleanup
-
-## Error Handling
-
-```python
-from azure.core.exceptions import HttpResponseError
-
-try:
-    agent = project_client.agents.create_agent(
-        model=os.environ["MODEL_DEPLOYMENT_NAME"],
-        name="my-agent", instructions="You are helpful."
-    )
-except HttpResponseError as e:
-    if e.status_code == 429:
-        print("Rate limited — wait and retry with exponential backoff.")
-    elif e.status_code == 401:
-        print("Authentication failed — check credentials.")
-    else:
-        print(f"Error: {e.message}")
-```
-
-### Context Manager for Agent Cleanup
-
-```python
-from contextlib import contextmanager
-
-@contextmanager
-def temporary_agent(project_client, **kwargs):
-    agent = project_client.agents.create_agent(**kwargs)
-    try:
-        yield agent
-    finally:
-        project_client.agents.delete_agent(agent.id)
