+# Create/Get Agent API
+
+## Context and Problem Statement
+
+There is a misalignment between the create/get agent API in the .NET and Python implementations.
+
+In .NET, the `CreateAIAgent` method can create either a local instance of an agent or a remote instance if the backend provider supports it. For remote agents, once the agent is created, you can retrieve an existing remote agent by using the `GetAIAgent` method. If a backend provider doesn't support remote agents, `CreateAIAgent` just initializes a new local agent instance and `GetAIAgent` is not available. There is also a `BuildAIAgent` method, which is an extension for the `ChatClientBuilder` class from `Microsoft.Extensions.AI`. It builds pipelines of `IChatClient` instances with an `IServiceProvider`. This functionality does not exist in Python, so `BuildAIAgent` is out of scope.
+
+In Python, there is only one `create_agent` method, which always creates a local instance of the agent. If the backend provider supports remote agents, the remote agent is created only on the first `agent.run()` invocation.
+
+Below is a short summary of different providers and their APIs in .NET:
+
+| Package | Method | Behavior | Python support |
+|---|---|---|---|
+| Microsoft.Agents.AI | `CreateAIAgent` (based on `IChatClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
+| Microsoft.Agents.AI.Anthropic | `CreateAIAgent` (based on `IBetaService` and `IAnthropicClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`AnthropicClient` inherits `BaseChatClient`, which exposes `create_agent`). |
+| Microsoft.Agents.AI.AzureAI (V2) | `GetAIAgent` (based on `AIProjectClient` with `AgentReference`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
+| Microsoft.Agents.AI.AzureAI (V2) | `GetAIAgent`/`GetAIAgentAsync` (with `Name`/`ChatClientAgentOptions`) | Fetches `AgentRecord` via HTTP, then creates a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.AzureAI (V2) | `CreateAIAgent`/`CreateAIAgentAsync` (based on `AIProjectClient`) | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `GetAIAgent` (based on `PersistentAgentsClient` with `PersistentAgent`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
+| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `GetAIAgent`/`GetAIAgentAsync` (with `AgentId`) | Fetches `PersistentAgent` via HTTP, then creates a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `CreateAIAgent`/`CreateAIAgentAsync` | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.OpenAI | `GetAIAgent` (based on `AssistantClient` with `Assistant`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
+| Microsoft.Agents.AI.OpenAI | `GetAIAgent`/`GetAIAgentAsync` (with `AgentId`) | Fetches `Assistant` via HTTP, then creates a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.OpenAI | `CreateAIAgent`/`CreateAIAgentAsync` (based on `AssistantClient`) | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
+| Microsoft.Agents.AI.OpenAI | `CreateAIAgent` (based on `ChatClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
+| Microsoft.Agents.AI.OpenAI | `CreateAIAgent` (based on `OpenAIResponseClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
+
+Another difference between Python and .NET implementation is that in .NET `CreateAIAgent`/`GetAIAgent` methods are implemented as extension methods based on underlying SDK client, like `AIProjectClient` from Azure AI or `AssistantClient` from OpenAI:
+
+```csharp
+// Definition
+public static ChatClientAgent CreateAIAgent(
+    this AIProjectClient aiProjectClient,
+    string name,
+    string model,
+    string instructions,
+    string? description = null,
+    IList<AITool>? tools = null,
+    Func<IChatClient, IChatClient>? clientFactory = null,
+    IServiceProvider? services = null,
+    CancellationToken cancellationToken = default)
+{ }
+
+// Usage
+AIProjectClient aiProjectClient = new(new Uri(endpoint), new AzureCliCredential()); // Initialization of underlying SDK client
+
+var newAgent = await aiProjectClient.CreateAIAgentAsync(name: AgentName, model: deploymentName, instructions: AgentInstructions, tools: [tool]); // ChatClientAgent creation from underlying SDK client
+
+// Alternative usage (same as extension method, just explicit syntax)
+var newAgent = await AzureAIProjectChatClientExtensions.CreateAIAgentAsync(
+    aiProjectClient,
+    name: AgentName,
+    model: deploymentName,
+    instructions: AgentInstructions,
+    tools: [tool]);
+```
+
+Python doesn't support extension methods. Currently `create_agent` method is defined on `BaseChatClient`, but this method only creates a local instance of `ChatAgent` and it can't create remote agents for providers that support it for a couple of reasons:
+
+- It's defined as non-async.
+- `BaseChatClient` implementation is stateful for providers like Azure AI or OpenAI Assistants. The implementation stores agent/assistant metadata like `AgentId` and `AgentName`, so currently it's not possible to create different instances of `ChatAgent` from a single `BaseChatClient` in case if the implementation is stateful.
+
+## Decision Drivers
+
+- API should be aligned between .NET and Python.
+- API should be intuitive and consistent between backend providers in .NET and Python.
+
+## Considered Options
+
+Add missing implementations on the Python side. This should include the following:
+
+### agent-framework-azure-ai (both V1 and V2)
+
+- Add a `get_agent` method that accepts an underlying SDK agent instance and creates a local instance of `ChatAgent`.
+- Add a `get_agent` method that accepts an agent identifier, performs an additional HTTP request to fetch agent data, and then creates a local instance of `ChatAgent`.
+- Override the `create_agent` method from `BaseChatClient` to create a remote agent instance and wrap it into a local `ChatAgent`.
+
+.NET:
+
+```csharp
+var agent1 = new AIProjectClient(...).GetAIAgent(agentInstanceFromSdkType); // Creates a local ChatClientAgent instance from Azure.AI.Projects.OpenAI.AgentReference 
+var agent2 = new AIProjectClient(...).GetAIAgent(agentName); // Fetches agent data, creates a local ChatClientAgent instance
+var agent3 = new AIProjectClient(...).CreateAIAgent(...); // Creates a remote agent, returns a local ChatClientAgent instance
+```
+
+### agent-framework-core (OpenAI Assistants)
+
+- Add a `get_agent` method that accepts an underlying SDK agent instance and creates a local instance of `ChatAgent`.
+- Add a `get_agent` method that accepts an agent name, performs an additional HTTP request to fetch agent data, and then creates a local instance of `ChatAgent`.
+- Override the `create_agent` method from `BaseChatClient` to create a remote agent instance and wrap it into a local `ChatAgent`.
+
+.NET:
+
+```csharp
+var agent1 = new AssistantClient(...).GetAIAgent(agentInstanceFromSdkType); // Creates a local ChatClientAgent instance from OpenAI.Assistants.Assistant
+var agent2 = new AssistantClient(...).GetAIAgent(agentId); // Fetches agent data, creates a local ChatClientAgent instance
+var agent3 = new AssistantClient(...).CreateAIAgent(...); // Creates a remote agent, returns a local ChatClientAgent instance
+```
+
+### Possible Python implementations
+
+Methods like `create_agent` and `get_agent` should be implemented separately or defined on some stateless component that will allow to create multiple agents from the same instance/place.
+
+Possible options:
+
+#### Option 1: Module-level functions
+
+Implement free functions in the provider package that accept the underlying SDK client as the first argument (similar to .NET extension methods, but expressed in Python).
+
+Example:
+
+```python
+from agent_framework.azure import create_agent, get_agent
+
+ai_project_client = AIProjectClient(...)
+
+# Creates a remote agent first, then returns a local ChatAgent wrapper
+created_agent = await create_agent(
+    ai_project_client,
+    name="",
+    instructions="",
+    tools=[tool],
+)
+
+# Gets an existing remote agent and returns a local ChatAgent wrapper
+first_agent = await get_agent(ai_project_client, agent_id=agent_id)
+
+# Wraps an SDK agent instance (no extra HTTP call)
+second_agent = get_agent(ai_project_client, agent_reference)
+```
+
+Pros:
+
+- Naturally supports async `create_agent` / `get_agent`.
+- Supports multiple agents per SDK client.
+- Closest conceptual match to .NET extension methods while staying Pythonic.
+
+Cons:
+
+- Discoverability is lower (users need to know where the functions live).
+- Verbose when creating multiple agents (client must be passed every time):
+
+  ```python
+  agent1 = await azure_agents.create_agent(client, name="Agent1", ...)
+  agent2 = await azure_agents.create_agent(client, name="Agent2", ...)
+  ```
+
+#### Option 2: Provider object
+
+Introduce a dedicated provider type that is constructed from the underlying SDK client, and exposes async `create_agent` / `get_agent` methods.
+
+Example:
+
+```python
+from agent_framework.azure import AzureAIAgentProvider
+
+ai_project_client = AIProjectClient(...)
+provider = AzureAIAgentProvider(ai_project_client)
+
+agent = await provider.create_agent(
+    name="",
+    instructions="",
+    tools=[tool],
+)
+
+agent = await provider.get_agent(agent_id=agent_id)
+agent = provider.get_agent(agent_reference=agent_reference)
+```
+
+Pros:
+
+- High discoverability and clear grouping of related behavior.
+- Keeps SDK clients unchanged and supports multiple agents per SDK client.
+- Concise when creating multiple agents (client passed once):
+
+  ```python
+  provider = AzureAIAgentProvider(ai_project_client)
+  agent1 = await provider.create_agent(name="Agent1", ...)
+  agent2 = await provider.create_agent(name="Agent2", ...)
+  ```
+
+Cons:
+
+- Adds a new public concept/type for users to learn.
+
+#### Option 3: Inheritance (SDK client subclass)
+
+Create a subclass of the underlying SDK client and add `create_agent` / `get_agent` methods.
+
+Example:
+
+```python
+class ExtendedAIProjectClient(AIProjectClient):
+    async def create_agent(self, *, name: str, model: str, instructions: str, **kwargs) -> ChatAgent:
+        ...
+
+    async def get_agent(self, *, agent_id: str | None = None, sdk_agent=None, **kwargs) -> ChatAgent:
+        ...
+
+client = ExtendedAIProjectClient(...)
+agent = await client.create_agent(name="", instructions="")
+```
+
+Pros:
+
+- Discoverable and ergonomic call sites.
+- Mirrors the .NET “methods on the client” feeling.
+
+Cons:
+
+- Many SDK clients are not designed for inheritance; SDK upgrades can break subclasses.
+- Users must opt into subclass everywhere.
+- Typing/initialization can be tricky if the SDK client has non-trivial constructors.
+
+#### Option 4: Monkey patching
+
+Attach `create_agent` / `get_agent` methods to an SDK client class (or instance) at runtime.
+
+Example:
+
+```python
+def _create_agent(self, *, name: str, model: str, instructions: str, **kwargs) -> ChatAgent:
+    ...
+
+AIProjectClient.create_agent = _create_agent  # monkey patch
+```
+
+Pros:
+
+- Produces “extension method-like” call sites without wrappers or subclasses.
+
+Cons:
+
+- Fragile across SDK updates and difficult to type-check.
+- Surprising behavior (global side effects), potential conflicts across packages.
+- Harder to support/debug, especially in larger apps and test suites.
+
+## Decision Outcome
+
+Implement `create_agent`/`get_agent`/`as_agent` API via **Option 2: Provider object**.
+
+### Rationale
+
+| Aspect | Option 1 (Functions) | Option 2 (Provider) |
+|--------|----------------------|---------------------|
+| Multiple implementations | One package may contain V1, V2, and other agent types. Function names like `create_agent` become ambiguous - which agent type does it create? | Each provider class is explicit: `AzureAIAgentsProvider` vs `AzureAIProjectAgentProvider` |
+| Discoverability | Users must know to import specific functions from the package | IDE autocomplete on provider instance shows all available methods |
+| Client reuse | SDK client must be passed to every function call: `create_agent(client, ...)`, `get_agent(client, ...)` | SDK client passed once at construction: `provider = Provider(client)` |
+
+**Option 1 example:**
+```python
+from agent_framework.azure import create_agent, get_agent
+agent1 = await create_agent(client, name="Agent1", ...)  # Which agent type, V1 or V2?
+agent2 = await create_agent(client, name="Agent2", ...)  # Repetitive client passing
+```
+
+**Option 2 example:**
+```python
+from agent_framework.azure import AzureAIProjectAgentProvider
+provider = AzureAIProjectAgentProvider(client)  # Clear which service, client passed once
+agent1 = await provider.create_agent(name="Agent1", ...)
+agent2 = await provider.create_agent(name="Agent2", ...)
+```
+
+### Method Naming
+
+| Operation | Python | .NET | Async |
+|-----------|--------|------|-------|
+| Create on service | `create_agent()` | `CreateAIAgent()` | Yes |
+| Get from service | `get_agent(id=...)` | `GetAIAgent(agentId)` | Yes |
+| Wrap SDK object | `as_agent(reference)` | `AsAIAgent(agentInstance)` | No |
+
+The method names (`create_agent`, `get_agent`) do not explicitly mention "service" or "remote" because:
+- In Python, the provider class name explicitly identifies the service (`AzureAIAgentsProvider`, `OpenAIAssistantProvider`), making additional qualifiers in method names redundant.
+- In .NET, these are extension methods on `AIProjectClient` or `AssistantClient`, which already imply service operations.
+
+### Provider Class Naming
+
+| Package | Provider Class | SDK Client | Service |
+|---------|---------------|------------|---------|
+| `agent_framework.azure` | `AzureAIProjectAgentProvider` | `AIProjectClient` | Azure AI Agent Service, based on Responses API (V2) |
+| `agent_framework.azure` | `AzureAIAgentsProvider` | `AgentsClient` | Azure AI Agent Service (V1) |
+| `agent_framework.openai` | `OpenAIAssistantProvider` | `AsyncOpenAI` | OpenAI Assistants API |
+
+> **Note:** Azure AI naming is temporary. Final naming will be updated according to Azure AI / Microsoft Foundry renaming decisions.
+
+### Usage Examples
+
+#### Azure AI Agent Service V2 (based on Responses API)
+
+```python
+from agent_framework.azure import AzureAIProjectAgentProvider
+from azure.ai.projects import AIProjectClient
+
+client = AIProjectClient(endpoint, credential)
+provider = AzureAIProjectAgentProvider(client)
+
+# Create new agent on service
+agent = await provider.create_agent(name="MyAgent", model="gpt-4", instructions="...")
+
+# Get existing agent by name
+agent = await provider.get_agent(agent_name="MyAgent")
+
+# Wrap already-fetched SDK object (no HTTP calls)
+agent_ref = await client.agents.get("MyAgent")
+agent = provider.as_agent(agent_ref)
+```
+
+#### Azure AI Persistent Agents V1
+
+```python
+from agent_framework.azure import AzureAIAgentsProvider
+from azure.ai.agents import AgentsClient
+
+client = AgentsClient(endpoint, credential)
+provider = AzureAIAgentsProvider(client)
+
+agent = await provider.create_agent(name="MyAgent", model="gpt-4", instructions="...")
+agent = await provider.get_agent(agent_id="persistent-agent-456")
+agent = provider.as_agent(persistent_agent)
+```
+
+#### OpenAI Assistants
+
+```python
+from agent_framework.openai import OpenAIAssistantProvider
+from openai import OpenAI
+
+client = OpenAI()
+provider = OpenAIAssistantProvider(client)
+
+agent = await provider.create_agent(name="MyAssistant", model="gpt-4", instructions="...")
+agent = await provider.get_agent(assistant_id="asst_123")
+agent = provider.as_agent(assistant)
+```
+
+#### Local-Only Agents (No Provider)
+
+Current method `create_agent` (python) / `CreateAIAgent` (.NET) can be renamed to `as_agent` (python) / `AsAIAgent` (.NET) to emphasize the conversion logic rather than creation/initialization logic and to avoid collision with `create_agent` method for remote calls.
+
+```python
+from agent_framework import ChatAgent
+from agent_framework.openai import OpenAIChatClient
+
+# Convert chat client to ChatAgent (no remote service involved)
+client = OpenAIChatClient(model="gpt-4")
+agent = client.as_agent(name="LocalAgent", instructions="...") # instead of create_agent
+```
+
+### Adding New Agent Types
+
+Python:
+
+1. Create provider class in appropriate package.
+2. Implement `create_agent`, `get_agent`, `as_agent` as applicable.
+
+.NET:
+
+1. Create static class for extension methods.
+2. Implement `CreateAIAgentAsync`, `GetAIAgentAsync`, `AsAIAgent` as applicable.

+
+# Leveraging TypedDict and Generic Options in Python Chat Clients
+
+## Context and Problem Statement
+
+The Agent Framework Python SDK provides multiple chat client implementations for different providers (OpenAI, Anthropic, Azure AI, Bedrock, Ollama, etc.). Each provider has unique configuration options beyond the common parameters defined in `ChatOptions`. Currently, developers using these clients lack type safety and IDE autocompletion for provider-specific options, leading to runtime errors and a poor developer experience.
+
+How can we provide type-safe, discoverable options for each chat client while maintaining a consistent API across all implementations?
+
+## Decision Drivers
+
+- **Type Safety**: Developers should get compile-time/static analysis errors when using invalid options
+- **IDE Support**: Full autocompletion and inline documentation for all available options
+- **Extensibility**: Users should be able to define custom options that extend provider-specific options
+- **Consistency**: All chat clients should follow the same pattern for options handling
+- **Provider Flexibility**: Each provider can expose its unique options without affecting the common interface
+
+## Considered Options
+
+- **Option 1: Status Quo - Class `ChatOptions` with `**kwargs`**
+- **Option 2: TypedDict with Generic Type Parameters**
+
+### Option 1: Status Quo - Class `ChatOptions` with `**kwargs`
+
+The current approach uses a base `ChatOptions` Class with common parameters, and provider-specific options are passed via `**kwargs` or loosely typed dictionaries.
+
+```python
+# Current usage - no type safety for provider-specific options
+response = await client.get_response(
+    messages=messages,
+    temperature=0.7,
+    top_k=40,
+    random=42, # No validation
+)
+```
+
+**Pros:**
+- Simple implementation
+- Maximum flexibility
+
+**Cons:**
+- No type checking for provider-specific options
+- No IDE autocompletion for available options
+- Runtime errors for typos or invalid options
+- Documentation must be consulted for each provider
+
+### Option 2: TypedDict with Generic Type Parameters (Chosen)
+
+Each chat client is parameterized with a TypeVar bound to a provider-specific `TypedDict` that extends `ChatOptions`. This enables full type safety and IDE support.
+
+```python
+# Provider-specific TypedDict
+class AnthropicChatOptions(ChatOptions, total=False):
+    """Anthropic-specific chat options."""
+    top_k: int
+    thinking: ThinkingConfig
+    # ... other Anthropic-specific options
+
+# Generic chat client
+class AnthropicChatClient(ChatClientBase[TAnthropicChatOptions]):
+    ...
+
+client = AnthropicChatClient(...)
+
+# Usage with full type safety
+response = await client.get_response(
+    messages=messages,
+    options={
+        "temperature": 0.7,
+        "top_k": 40,
+        "random": 42,  # fails type checking and IDE would flag this
+    }
+)
+
+# Users can extend for custom options
+class MyAnthropicOptions(AnthropicChatOptions, total=False):
+    custom_field: str
+
+
+client = AnthropicChatClient[MyAnthropicOptions](...)
+
+# Usage of custom options with full type safety
+response = await client.get_response(
+    messages=messages,
+    options={
+        "temperature": 0.7,
+        "top_k": 40,
+        "custom_field": "value",
+    }
+)
+
+```
+
+**Pros:**
+- Full type safety with static analysis
+- IDE autocompletion for all options
+- Compile-time error detection
+- Self-documenting through type hints
+- Users can extend options for their specific needs or advances in models
+
+**Cons:**
+- More complex implementation
+- Some type: ignore comments needed for TypedDict field overrides
+- Minor: Requires TypeVar with default (Python 3.13+ or typing_extensions)
+
+> [NOTE!]
+> In .NET this is already achieved through overloads on the `GetResponseAsync` method for each provider-specific options class, e.g., `AnthropicChatOptions`, `OpenAIChatOptions`, etc. So this does not apply to .NET.
+
+### Implementation Details
+
+1. **Base Protocol**: `ChatClientProtocol[TOptions]` is generic over options type, with default set to `ChatOptions` (the new TypedDict)
+2. **Provider TypedDicts**: Each provider defines its options extending `ChatOptions`
+    They can even override fields with type=None to indicate they are not supported.
+3. **TypeVar Pattern**: `TProviderOptions = TypeVar("TProviderOptions", bound=TypedDict, default=ProviderChatOptions, contravariant=True)`
+4. **Option Translation**: Common options are kept in place,and explicitly documented in the Options class how they are used. (e.g., `user` → `metadata.user_id`) in `_prepare_options` (for Anthropic) to preserve easy use of common options.
+
+## Decision Outcome
+
+Chosen option: **"Option 2: TypedDict with Generic Type Parameters"**, because it provides full type safety, excellent IDE support with autocompletion, and allows users to extend provider-specific options for their use cases. Extended this Generic to ChatAgents in order to also properly type the options used in agent construction and run methods.
+
+See [typed_options.py](../../python/samples/getting_started/chat_client/typed_options.py) for a complete example demonstrating the usage of typed options with custom extensions.

+# Simplify Python Get Response API into a single method
+
+## Context and Problem Statement
+
+Currently chat clients must implement two separate methods to get responses, one for streaming and one for non-streaming. This adds complexity to the client implementations and increases the maintenance burden. This was likely done because the .NET version cannot do proper typing with a single method, in Python this is possible and this for instance is also how the OpenAI python client works, this would then also make it simpler to work with the Python version because there is only one method to learn about instead of two.
+
+## Implications of this change
+
+### Current Architecture Overview
+
+The current design has **two separate methods** at each layer:
+
+| Layer | Non-streaming | Streaming |
+|-------|---------------|-----------|
+| **Protocol** | `get_response()` → `ChatResponse` | `get_streaming_response()` → `AsyncIterable[ChatResponseUpdate]` |
+| **BaseChatClient** | `get_response()` (public) | `get_streaming_response()` (public) |
+| **Implementation** | `_inner_get_response()` (private) | `_inner_get_streaming_response()` (private) |
+
+### Key Usage Areas Identified
+
+#### 1. **ChatAgent** (_agents.py)
+- `run()` → calls `self.chat_client.get_response()`
+- `run_stream()` → calls `self.chat_client.get_streaming_response()`
+
+These are parallel methods on the agent, so consolidating the client methods would **not break** the agent API. You could keep `agent.run()` and `agent.run_stream()` unchanged while internally calling `get_response(stream=True/False)`.
+
+#### 2. **Function Invocation Decorator** (_tools.py)
+This is **the most impacted area**. Currently:
+- `_handle_function_calls_response()` decorates `get_response`
+- `_handle_function_calls_streaming_response()` decorates `get_streaming_response`
+- The `use_function_invocation` class decorator wraps **both methods separately**
+
+**Impact**: The decorator logic is almost identical (~200 lines each) with small differences:
+- Non-streaming collects response, returns it
+- Streaming yields updates, returns async iterable
+
+With a unified method, you'd need **one decorator** that:
+- Checks the `stream` parameter
+- Uses `@overload` to determine return type
+- Handles both paths with conditional logic
+- The new decorator could be applied just on the method, instead of the whole class.
+
+This would **reduce code duplication** but add complexity to a single function.
+
+#### 3. **Observability/Instrumentation** (observability.py)
+Same pattern as function invocation:
+- `_trace_get_response()` wraps `get_response`
+- `_trace_get_streaming_response()` wraps `get_streaming_response`
+- `use_instrumentation` decorator applies both
+
+**Impact**: Would need consolidation into a single tracing wrapper.
+
+#### 4. **Chat Middleware** (_middleware.py)
+The `use_chat_middleware` decorator also wraps both methods separately with similar logic.
+
+#### 5. **AG-UI Client** (_client.py)
+Wraps both methods to unwrap server function calls:
+```python
+original_get_streaming_response = chat_client.get_streaming_response
+original_get_response = chat_client.get_response
+```
+
+#### 6. **Provider Implementations** (all subpackages)
+All subclasses implement both `_inner_*` methods, except:
+- OpenAI Assistants Client (and similar clients, such as Foundry Agents V1) - it implements `_inner_get_response` by calling `_inner_get_streaming_response`
+
+### Implications of Consolidation
+
+| Aspect | Impact |
+|--------|--------|
+| **Type Safety** | Overloads work well: `@overload` with `Literal[True]` → `AsyncIterable`, `Literal[False]` → `ChatResponse`. Runtime return type based on `stream` param. |
+| **Breaking Change** | **Major breaking change** for anyone implementing custom chat clients. They'd need to update from 2 methods to 1 (or 2 inner methods to 1). |
+| **Decorator Complexity** | All 3 decorator systems (function invocation, middleware, observability) would need refactoring to handle both paths in one wrapper. |
+| **Code Reduction** | Significant reduction in _tools.py (~200 lines of near-duplicate code) and other decorators. |
+| **Samples/Tests** | Many samples call `get_streaming_response()` directly - would need updates. |
+| **Protocol Simplification** | `ChatClientProtocol` goes from 2 methods + 1 property to 1 method + 1 property. |
+
+### Recommendation
+
+The consolidation makes sense architecturally, but consider:
+
+1. **The overload pattern with `stream: bool`** works well in Python typing:
+   ```python
+   @overload
+   async def get_response(self, messages, *, stream: Literal[True] = True, ...) -> AsyncIterable[ChatResponseUpdate]: ...
+   @overload
+   async def get_response(self, messages, *, stream: Literal[False] = False, ...) -> ChatResponse: ...
+   ```
+
+2. **The decorator complexity** is the biggest concern. The current approach of separate decorators for separate methods is cleaner than conditional logic inside one wrapper.
+
+## Decision Drivers
+
+- Reduce code needed to implement a Chat Client, simplify the public API for chat clients
+- Reduce code duplication in decorators and middleware
+- Maintain type safety and clarity in method signatures
+
+## Considered Options
+
+1. Status quo: Keep separate methods for streaming and non-streaming
+2. Consolidate into a single `get_response` method with a `stream` parameter
+3. Option 2 plus merging `agent.run` and `agent.run_stream` into a single method with a `stream` parameter as well
+
+## Option 1: Status Quo
+- Good: Clear separation of streaming vs non-streaming logic
+- Good: Aligned with .NET design, although it is already `run` for Python and `RunAsync` for .NET
+- Bad: Code duplication in decorators and middleware
+- Bad: More complex client implementations
+
+## Option 2: Consolidate into Single Method
+- Good: Simplified public API for chat clients
+- Good: Reduced code duplication in decorators
+- Good: Smaller API footprint for users to get familiar with
+- Good: People using OpenAI directly already expect this pattern
+- Bad: Increased complexity in decorators and middleware
+- Bad: Less alignment with .NET design (`get_response(stream=True)` vs `GetStreamingResponseAsync`)
+
+## Option 3: Consolidate + Merge Agent and Workflow Methods
+- Good: Further simplifies agent and workflow implementation
+- Good: Single method for all chat interactions
+- Good: Smaller API footprint for users to get familiar with
+- Good: People using OpenAI directly already expect this pattern
+- Good: Workflows internally already use a single method (_run_workflow_with_tracing), so would eliminate public API duplication as well, with hardly any code changes
+- Bad: More breaking changes for agent users
+- Bad: Increased complexity in agent implementation
+- Bad: More extensive misalignment with .NET design (`run(stream=True)` vs `RunStreamingAsync` in addition to `get_response` change)
+
+## Misc
+
+Smaller questions to consider:
+- Should default be `stream=False` or `stream=True`? (Current is False)
+    - Default to `False` makes it simpler for new users, as non-streaming is easier to handle.
+    - Default to `False` aligns with existing behavior.
+    - Streaming tends to be faster, so defaulting to `True` could improve performance for common use cases.
+    - Should this differ between ChatClient, Agent and Workflows? (e.g., Agent and Workflow defaults to streaming, ChatClient to non-streaming)
+
+## Decision Outcome
+
+Chosen Option: **Option 3: Consolidate + Merge Agent and Workflow Methods**
+
+Since this is the most pythonic option and it reduces the API surface and code duplication the most, we will go with this option.
+We will keep the default of `stream=False` for all methods to maintain backward compatibility and simplicity for new users.
