+# Foundry agent surface stays centered on `ChatClientAgent`
+
+## Context
+
+The Microsoft Foundry integration exposes two distinct usage patterns:
+
+1. Direct Responses usage, where callers provide model, instructions, and tools at runtime.
+2. Server-side versioned agents, where callers create and manage `AgentVersion` resources through `AIProjectClient.Agents`.
+
+We briefly explored adding public wrapper types such as `FoundryAgent`, `FoundryVersionedAgent`, and `FoundryResponsesChatClient` to make those paths feel more specialized. That direction created extra public types, duplicated existing `ChatClientAgent` behavior, and pushed samples toward compatibility helpers instead of the native Azure SDK flow.
+
+## Decision
+
+Keep the public surface centered on `ChatClientAgent`.
+
+- Direct Responses scenarios use `AIProjectClient.AsAIAgent(...)`.
+- Server-side versioned scenarios use native `AIProjectClient.Agents` APIs to create or retrieve agent resources, then wrap `AgentRecord` or `AgentVersion` with `AIProjectClient.AsAIAgent(...)`.
+- Compatibility helpers such as `AIProjectClient.CreateAIAgentAsync(...)` and `AIProjectClient.GetAIAgentAsync(...)` remain only as obsolete migration shims.
+- Public wrapper types `FoundryAgent`, `FoundryVersionedAgent`, `FoundryResponsesChatClient`, and `FoundryResponsesChatClientAgent` are not part of the chosen direction.
+
+## Why
+
+- `ChatClientAgent` is already the framework abstraction used everywhere else.
+- `AIProjectClient` is the native Azure SDK entry point for versioned agent lifecycle operations.
+- A single agent abstraction avoids parallel type hierarchies for the same backend.
+- Samples become clearer when they show either:
+  - direct Responses construction via `AIProjectClient.AsAIAgent(...)`, or
+  - native Foundry resource management via `AIProjectClient.Agents`.
+
+## Consequences
+
+### Direct Responses path
+
+Use the convenience overloads on `AIProjectClient`:
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+ChatClientAgent agent = aiProjectClient.AsAIAgent(
+    model: deploymentName,
+    instructions: "You are good at telling jokes.",
+    name: "JokerAgent");
+```
+
+Or use composed `ChatClientAgent`
+
+```csharp
+ProjectResponsesClient projectResponsesClient = new(new Uri(endpoint), new DefaultAzureCredential(), new AgentReference($"model:{deploymentName}"));
+
+ChatClientAgent agent = new(
+    chatClient: projectResponsesClient.AsIChatClient(),
+    instructions: "You are good at telling jokes.",
+    name: "JokerAgent");
+```
+
+This path is code-first and does not create a persistent server-side agent.
+
+### Versioned agent path
+
+Use the convenience overloads on `AIProjectClient`:
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+AgentVersion version = await aiProjectClient.Agents.CreateAgentVersionAsync(
+    "JokerAgent",
+    new AgentVersionCreationOptions(
+        new PromptAgentDefinition(deploymentName)
+        {
+            Instructions = "You are good at telling jokes."
+        }));
+
+ChatClientAgent agent = aiProjectClient.AsAIAgent(version);
+```
+
+Or use composed `ChatClientAgent`
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+AgentVersion version = await aiProjectClient.Agents.CreateAgentVersionAsync(
+    "JokerAgent",
+    new AgentVersionCreationOptions(
+        new PromptAgentDefinition(deploymentName)
+        {
+            Instructions = "You are good at telling jokes."
+        }));
+
+ProjectResponsesClient projectResponsesClient = aiProjectClient
+    .GetProjectOpenAIClient()
+    .GetProjectResponsesClientForAgent(new AgentReference(version.Name, version.Version));
+
+ChatClientAgent agent = new(
+    chatClient: projectResponsesClient.AsIChatClient(),
+    name: "JokerAgent");
+```
+
+### Samples
+
+- `FoundryAgents/` samples show the direct Responses path with `AIProjectClient.AsAIAgent(...)`.
+- `FoundryVersionedAgents/` samples should show native `AIProjectClient.Agents` create/get/delete flows plus `AsAIAgent(...)`.
+
+### Compatibility APIs
+
+Obsolete helper extensions remain only to ease migration of existing code. New samples and new guidance should not be written against them.
+
+## Rejected direction
+
+Do not introduce or preserve separate public wrapper types whose main purpose is to forward to `ChatClientAgent` while carrying Foundry-specific naming.
+
+That approach:
+
+- duplicates lifecycle concepts already present on `AIProjectClient`,
+- fragments the public API,
+- complicates samples and docs,
+- and makes migration harder by encouraging wrapper-specific affordances.
