+# Creating an Agent from a ChatClient
+
+This sample demonstrates how to create an AI agent directly from an `OpenAI.Chat.ChatClient` instance using the `OpenAIChatClientAgent` class.
+
+## What This Sample Shows
+
+- **Direct ChatClient Creation**: Shows how to create an `OpenAI.Chat.ChatClient` from `OpenAI.OpenAIClient` and then use it to instantiate an agent
+- **OpenAIChatClientAgent**: Demonstrates using the OpenAI SDK primitives instead of the ones from Microsoft.Extensions.AI and Microsoft.Agents.AI abstractions
+- **Full Agent Capabilities**: Shows both regular and streaming invocation of the agent
+
+## Running the Sample
+
+1. Set the required environment variables:
+   ```bash
+   set OPENAI_API_KEY=your_api_key_here
+   set OPENAI_MODEL=gpt-4o-mini
+   ```
+
+2. Run the sample:
+   ```bash
+   dotnet run
+   ```
