+
+# What this sample demonstrates
+
+This sample demonstrates a **key advantage of code-based hosted agents**:
+
+- **Agents in Workflows** - Use AI agents as executors within a workflow pipeline
+
+Code-based agents can execute **any Python code** you write. This sample includes a multi-agent workflow where Writer and Reviewer agents collaborate to draft content and provide review feedback.
+
+The agent is hosted using the [Azure AI AgentServer SDK](https://pypi.org/project/azure-ai-agentserver-agentframework/) and can be deployed to Microsoft Foundry using the Azure Developer CLI.
+
+## How It Works
+
+### Agents in Workflows
+
+This sample demonstrates the integration of AI agents within a workflow pipeline. The workflow operates as follows:
+
+1. **Writer Agent** - Drafts content
+2. **Reviewer Agent** - Reviews the draft and provides concise, actionable feedback
+
+### Agent Hosting
+
+The agent workflow is hosted using the [Azure AI AgentServer SDK](https://pypi.org/project/azure-ai-agentserver-agentframework/),
+which provisions a REST API endpoint compatible with the OpenAI Responses protocol.
+
+### Agent Deployment
+
+The hosted agent workflow can be deployed to Microsoft Foundry using the Azure Developer CLI [ai agent](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry&tabs=cli#create-a-hosted-agent) extension.
+
+## Running the Agent Locally
+
+### Prerequisites
+
+Before running this sample, ensure you have:
+
+1. **Azure AI Foundry Project**
+   - Project created in [Azure AI Foundry](https://learn.microsoft.com/en-us/azure/ai-foundry/what-is-foundry?view=foundry#microsoft-foundry-portals)
+   - Chat model deployed (e.g., `gpt-4o` or `gpt-4.1`)
+   - Note your project endpoint URL and model deployment name
+
+2. **Azure CLI**
+   - Installed and authenticated
+   - Run `az login` and verify with `az account show`
+
+3. **Python 3.10 or higher**
+   - Verify your version: `python --version`
+   - If you have Python 3.9 or older, install a newer version:
+     - Windows: `winget install Python.Python.3.12`
+     - macOS: `brew install python@3.12`
+     - Linux: Use your package manager
+
+### Environment Variables
+
+Set the following environment variables (matching `agent.yaml`):
+
+- `PROJECT_ENDPOINT` - Your Azure AI Foundry project endpoint URL (required)
+- `MODEL_DEPLOYMENT_NAME` - The deployment name for your chat model (defaults to `gpt-4.1-mini`)
+
+This sample loads environment variables from a local `.env` file if present.
+
+Create a `.env` file in this directory with the following content:
+
+```
+PROJECT_ENDPOINT=https://<your-resource>.services.ai.azure.com/api/projects/<your-project>
+MODEL_DEPLOYMENT_NAME=gpt-4.1-mini
+```
+
+Or set them via PowerShell:
+
+```powershell
+# Replace with your actual values
+$env:PROJECT_ENDPOINT="https://<your-resource>.services.ai.azure.com/api/projects/<your-project>"
+$env:MODEL_DEPLOYMENT_NAME="gpt-4.1-mini"
+```
+
+### Setting Up a Virtual Environment
+
+It's recommended to use a virtual environment to isolate project dependencies:
+
+**macOS/Linux:**
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+```
+
+**Windows (PowerShell):**
+
+```powershell
+python -m venv .venv
+.\.venv\Scripts\Activate.ps1
+```
+
+### Installing Dependencies
+
+Install the required Python dependencies using pip:
+
+```bash
+pip install -r requirements.txt
+```
+
+### Running the Sample
+
+To run the agent, execute the following command in your terminal:
+
+```powershell
+python main.py
+```
+
+This will start the hosted agent locally on `http://localhost:8088/`.
+
+### Interacting with the Agent
+
+**PowerShell (Windows):**
+
+```powershell
+$body = @{
+   input = "Create a slogan for a new electric SUV that is affordable and fun to drive."
+    stream = $false
+} | ConvertTo-Json
+
+Invoke-RestMethod -Uri http://localhost:8088/responses -Method Post -Body $body -ContentType "application/json"
+```
+
+**Bash/curl (Linux/macOS):**
+
+```bash
+curl -sS -H "Content-Type: application/json" -X POST http://localhost:8088/responses \
+   -d '{"input": "Create a slogan for a new electric SUV that is affordable and fun to drive.","stream":false}'
+```
+
+### Deploying the Agent to Microsoft Foundry
+
+To deploy your agent to Microsoft Foundry, follow the comprehensive deployment guide at https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry&tabs=cli
+
+## Troubleshooting
+
+### Images built on Apple Silicon or other ARM64 machines do not work on our service
+
+We **recommend using `azd` cloud build**, which always builds images with the correct architecture.
+
+If you choose to **build locally**, and your machine is **not `linux/amd64`** (for example, an Apple Silicon Mac), the image will **not be compatible with our service**, causing runtime failures.
+
+**Fix for local builds**
+
+Use this command to build the image locally:
+
+```shell
+docker build --platform=linux/amd64 -t image .
+```
+
+This forces the image to be built for the required `amd64` architecture.
