Eduard van Valkenburg 5e056b672e Python: [BREAKING] Python: Provider-leading client design & OpenAI package extraction (#4818)
* Python: Provider-leading client design & OpenAI package extraction

Major refactoring of the Python Agent Framework client architecture:

- Extract OpenAI clients into new `agent-framework-openai` package
- Core package no longer depends on openai, azure-identity, azure-ai-projects
- Rename clients for discoverability: OpenAIResponsesClient → OpenAIChatClient,
  OpenAIChatClient → OpenAIChatCompletionClient
- Unify `model_id`/`deployment_name`/`model_deployment_name` → `model` param
- New FoundryChatClient for Azure AI Foundry Responses API
- New FoundryAgent/FoundryAgentClient for connecting to pre-configured Foundry agents
- Remove OpenAIBase/OpenAIConfigMixin from non-deprecated client MRO
- Deprecate AzureOpenAI* clients, AzureAIClient, OpenAIAssistantsClient
- Reorganize samples: azure_openai+azure_ai+azure_ai_agent → azure/
- ADR-0020: Provider-Leading Client Design

* fix: missing Agent imports in samples, .model_id → .model in foundry_local sample

* fix: CI failures — mypy errors, coverage targets, sample imports

- azure-ai mypy: add type ignores for TypedDict total=, model arg, forward ref
- Coverage: replace core.azure/openai targets with openai package target
- project_provider: add type annotation for opts dict

Single Agent Sample (Python)

This sample demonstrates how to use the Durable Extension for Agent Framework to create a simple Azure Functions app that hosts a single AI agent and provides direct HTTP API access for interactive conversations.

Key Concepts Demonstrated

  • Defining a simple agent with the Microsoft Agent Framework and wiring it into an Azure Functions app via the Durable Extension for Agent Framework.
  • Calling the agent through generated HTTP endpoints (/api/agents/Joker/run).
  • Managing conversation state with session identifiers, so multiple clients can interact with the agent concurrently without sharing context.

Prerequisites

Follow the common setup steps in ../README.md to install tooling, configure Azure OpenAI credentials, and install the Python dependencies for this sample.

Running the Sample

Send a prompt to the Joker agent:

Bash (Linux/macOS/WSL):

curl -i -X POST http://localhost:7071/api/agents/Joker/run \
     -d "Tell me a short joke about cloud computing."

PowerShell:

Invoke-RestMethod -Method Post -Uri http://localhost:7071/api/agents/Joker/run `
    -Body "Tell me a short joke about cloud computing."

The agent responds with a JSON payload that includes the generated joke.

Tip

To return immediately with an HTTP 202 response instead of waiting for the agent output, set the x-ms-wait-for-response header or include "wait_for_response": false in the request body. The default behavior waits for the response.

Expected Output

The default plain-text response looks like the following:

HTTP/1.1 200 OK
Content-Type: text/plain; charset=utf-8
x-ms-thread-id: 4f205157170244bfbd80209df383757e

Why did the cloud break up with the server?

Because it found someone more "uplifting"!

When you specify the x-ms-wait-for-response header or include "wait_for_response": false in the request body, the Functions host responds with an HTTP 202 and queues the request to run in the background. A typical response body looks like the following:

{
  "status": "accepted",
  "response": "Agent request accepted",
  "message": "Tell me a short joke about cloud computing.",
  "thread_id": "<guid>",
  "correlation_id": "<guid>"
}
