+# Agent Middleware 
+
+This sample demonstrates how to add middleware to intercept:
+- Chat client calls (global and per‑request)
+- Agent runs (guardrails and PII filtering)
+- Function calling (logging/override)
+
+## What This Sample Shows
+
+1. Azure OpenAI integration via `AzureOpenAIClient` and `AzureCliCredential`
+2. Chat client middleware using `ChatClientBuilder.Use(...)`
+3. Agent run middleware (PII redaction and wording guardrails)
+4. Function invocation middleware (logging and overriding a tool result)
+5. Per‑request chat client middleware
+6. Per‑request function pipeline with approval
+7. Combining agent‑level and per‑request middleware
+
+## Function Invocation Middleware
+
+Not all agents support function invocation middleware.
+
+Attempting to use function middleware on agents that do not wrap a ChatClientAgent or derives from it will throw an InvalidOperationException.
+
+## Prerequisites
+
+1. Environment variables:
+   - `AZURE_OPENAI_ENDPOINT`: Your Azure OpenAI endpoint
+   - `AZURE_OPENAI_DEPLOYMENT_NAME`: Chat deployment name (optional; defaults to `gpt-4o`)
+2. Sign in with Azure CLI (PowerShell):
+   ```powershell
+   az login
+   ```
+
+## Running the Sample
+
+Use PowerShell:
+```powershell
+cd dotnet/samples/GettingStarted/Agents/Agent_Step14_Middleware
+dotnet run
+```
