+# Using Function Tools with Approvals (Human-in-the-Loop)
+
+This sample demonstrates how to use function tools that require human approval before execution, implementing a human-in-the-loop workflow.
+
+## What this sample demonstrates
+
+- Creating approval-required function tools using ApprovalRequiredAIFunction
+- Handling user input requests for function approvals
+- Implementing human-in-the-loop approval workflows
+- Processing agent responses with pending approvals
+- Managing agent lifecycle (creation and deletion)
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 10 SDK or later
+- Azure Foundry service endpoint and deployment configured
+- Azure CLI installed and authenticated (for Azure credential authentication)
+
+**Note**: This demo uses Azure CLI credentials for authentication. Make sure you're logged in with `az login` and have access to the Azure Foundry resource. For more information, see the [Azure CLI documentation](https://learn.microsoft.com/cli/azure/authenticate-azure-cli-interactively).
+
+Set the following environment variables:
+
+```powershell
+$env:AZURE_FOUNDRY_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project" # Replace with your Azure Foundry resource endpoint
+$env:AZURE_FOUNDRY_PROJECT_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
+```
+
+## Run the sample
+
+Navigate to the FoundryAgents sample directory and run:
+
+```powershell
+cd dotnet/samples/GettingStarted/FoundryAgents
+dotnet run --project .\FoundryAgents_Step04_UsingFunctionToolsWithApprovals
+```
+
+## Expected behavior
+
+The sample will:
+
+1. Create an agent named "WeatherAssistant" with an approval-required GetWeather function tool
+2. Run the agent with a prompt asking about weather
+3. The agent will request approval before invoking the GetWeather function
+4. The sample will prompt the user to approve or deny the function call (enter 'Y' to approve)
+5. After approval, the function will be executed and the result returned to the agent
+6. Clean up resources by deleting the agent
+
+**Note**: For hosted agents with remote users, combine this sample with the Persisted Conversations sample to persist chat history while waiting for user approval.
