+# AG-UI Handoff Workflow Demo
+
+This demo is a full custom AG-UI application built on top of the new workflow abstractions in `agent_framework_ag_ui`.
+
+It includes:
+
+- A **backend** FastAPI AG-UI endpoint serving a **HandoffBuilder workflow** with:
+  - `triage_agent`
+  - `refund_agent`
+  - `order_agent`
+- Required **tool approval checkpoints**:
+  - `submit_refund` (`approval_mode="always_require"`)
+  - `submit_replacement` (`approval_mode="always_require"`)
+- A second **request-info resume** step (order agent asks for shipping preference)
+- A **frontend** React app that consumes AG-UI SSE events, renders workflow cards, and sends `resume.interrupts` payloads.
+
+The backend uses Azure OpenAI responses and supports intent-driven, non-linear handoff routing.
+
+This demo keeps workflow state per `thread_id`. When the assistant ends a case with `Case complete.`, the UI blocks
+later top-level input on that same thread and asks the user to start a new case explicitly instead of resuming a
+terminated workflow.
+
+## Folder Layout
+
+- `backend/server.py` - FastAPI + AG-UI endpoint + Handoff workflow
+- `frontend/` - Vite + React AG-UI client UI
+
+## Prerequisites
+
+- Python 3.10+
+- Node.js 18+
+- npm 9+
+- Azure AI project + model deployment configured in environment variables:
+  - `FOUNDRY_PROJECT_ENDPOINT`
+  - `FOUNDRY_MODEL`
+
+## 1) Run Backend
+
+From the Python repo root:
+
+```bash
+cd python
+uv sync
+uv run python samples/05-end-to-end/ag_ui_workflow_handoff/backend/server.py
+```
+
+Backend default URL:
+
+- `http://127.0.0.1:8891`
+- AG-UI endpoint: `POST http://127.0.0.1:8891/handoff_demo`
+
+## 2) Install Frontend Packages (npm)
+
+From the `python/` directory (where Step 1 left you):
+
+```bash
+cd samples/05-end-to-end/ag_ui_workflow_handoff/frontend
+npm install
+```
+
+## 3) Run Frontend Locally
+
+```bash
+npm run dev
+```
+
+Frontend default URL:
+
+- `http://127.0.0.1:5173`
+
+If you changed backend host/port, run with:
+
+```bash
+VITE_BACKEND_URL=http://127.0.0.1:8891 npm run dev
+```
+
+## 4) Demo Flow to Verify
+
+1. Click one of the starter prompts (or type a refund request).
+2. Refund Agent asks for an order number; reply with a numeric ID (for example: `987654`).
+3. If your initial request did not explicitly choose refund vs replacement, the agent asks a clarifying choice question.
+4. Wait for the `submit_refund` reviewer interrupt (built from your provided order ID).
+5. In the **HITL Reviewer Console** modal, click **Approve Tool Call**.
+6. If you asked for replacement, the Order agent asks for shipping preference; reply in the chat input (for example: `expedited`).
+7. When replacement is requested, wait for the `submit_replacement` reviewer interrupt and approve/reject it.
+8. If you asked for refund-only, the flow should close without replacement/shipping prompts.
+9. Confirm the case snapshot updates and workflow completion.
+10. After the case closes, another top-level message on the same thread is rejected with a notice.
+11. Click **Start New Case** to begin a fresh thread.
+
+## Important: `require_per_service_call_history_persistence`
+
+All agents participating in a handoff workflow **must** be constructed with
+`require_per_service_call_history_persistence=True`. The `HandoffBuilder` will
+raise a `ValueError` at build time if any participant is missing this flag.
+
+**Why this is required:** Handoff workflows use middleware that short-circuits
+tool calls via `MiddlewareTermination` when a handoff tool is invoked. Without
+per-service-call history persistence, local history providers would persist tool
+results that the service never received, causing call/result mismatches on
+subsequent turns.
+
+```python
+agent = Agent(
+    client=client,
+    name="my_agent",
+    require_per_service_call_history_persistence=True,  # Required for handoff
+)
+```
+
+## What This Validates
+
+- `add_agent_framework_fastapi_endpoint(...)` with `AgentFrameworkWorkflow(workflow_factory=...)`
+- Thread-scoped workflow state across turns
+- `RUN_FINISHED.interrupt` pause behavior
+- `resume.interrupts` continuation behavior
+- JSON resume payload coercion for `Content` and `list[Message]` workflow response types
+- Intent-driven routing between triage, refund, and order specialists (no forced linear path)
+- Multiple HITL approvals in one case (`submit_refund` + `submit_replacement`)

+"""AG-UI handoff workflow demo backend.
+
+This demo exposes a dynamic HandoffBuilder workflow through AG-UI.
+It intentionally includes two interrupt styles:
+
+1. Tool approval (`function_approval_request`) for `submit_refund` and `submit_replacement`
+2. Follow-up human input (`HandoffAgentUserRequest`) when an agent needs user details
+
+Run this server and pair it with the frontend in `../frontend`.

+# ChatKit Integration Sample with Weather Agent and Image Analysis
+
+This sample demonstrates how to integrate Microsoft Agent Framework with OpenAI ChatKit. It provides a complete implementation of a weather assistant with interactive widget visualization, image analysis, and file upload support.
+
+**Features:**
+
+- Weather information with interactive widgets
+- Image analysis using vision models
+- Current time queries
+- File upload with attachment storage
+- Chat interface with streaming responses
+- City selector widget with one-click weather

+
+### Server Implementation
+
+The sample implements a ChatKit server using the `ChatKitServer` base class from the `chatkit` package:
+
+**Core Components:**
+
+- **`WeatherChatKitServer`**: Custom ChatKit server implementation that:
+
+  - Extends `ChatKitServer[dict[str, Any]]`
+  - Uses Agent Framework's `Agent` with Azure OpenAI
+  - Converts ChatKit messages to Agent Framework format using `ThreadItemConverter`
+  - Streams responses back to ChatKit using `stream_agent_response`
+  - Creates and streams interactive widgets after agent responses
+
+- **`SQLiteStore`**: Data persistence layer that:
+
+  - Implements the `Store[dict[str, Any]]` protocol from ChatKit
+  - Persists threads, messages, and attachment metadata in SQLite
+  - Provides thread management and item history
+  - Stores attachment metadata for the upload lifecycle
+
+- **`FileBasedAttachmentStore`**: File storage implementation that:
+  - Implements the `AttachmentStore[dict[str, Any]]` protocol from ChatKit
+  - Stores uploaded files on the local filesystem (in `./uploads` directory)
+  - Generates upload URLs for two-phase file upload
+  - Saves attachment metadata to the data store for upload tracking
+  - Provides preview URLs for images
+
+**Key Integration Points:**
+
+```python
+# Converting ChatKit messages to Agent Framework
+converter = ThreadItemConverter(
+    attachment_data_fetcher=self._fetch_attachment_data
+)
+agent_messages = await converter.to_agent_input(user_message_item)
+
+# Running agent and streaming back to ChatKit
+async for event in stream_agent_response(
+    self.weather_agent.run(agent_messages, stream=True),
+    thread_id=thread.id,
+):
+    yield event
+
+# Streaming widgets
+widget = render_weather_widget(weather_data)
+async for event in stream_widget(thread_id=thread.id, widget=widget):
+    yield event
+```
+
+## Installation and Setup
+
+### Prerequisites
+
+- Python 3.10+
+- Node.js 18.18+ and npm 9+
+- Azure OpenAI service configured
+- Azure CLI for authentication (`az login`)
+
+### Network Requirements
+
+> **Important:** This sample uses the OpenAI ChatKit frontend, which requires internet connectivity to OpenAI services.
+
+The frontend makes outbound requests to:
+
+- `cdn.platform.openai.com` - ChatKit UI library (required)
+- `chatgpt.com` - Configuration endpoint
+- `api-js.mixpanel.com` - Telemetry
+
+**This sample is not suitable for air-gapped or network-restricted environments.** The ChatKit frontend library cannot be self-hosted. See [Limitations](#limitations) for details.
+
+### Domain Key Configuration
+
+For **local development**, the sample uses a default domain key (`domain_pk_localhost_dev`).
+
+For **production deployment**:
+
+1. Register your domain at [platform.openai.com](https://platform.openai.com/settings/organization/security/domain-allowlist)
+2. Create a `.env` file in the `frontend` directory:
+
+   ```
+   VITE_CHATKIT_API_DOMAIN_KEY=your_domain_key_here
+   ```
+
+### Backend Setup
+
+1. **Install Python packages:**
+
+```bash
+cd python/samples/05-end-to-end/chatkit-integration
+pip install agent-framework-chatkit fastapi uvicorn azure-identity
+```
+
+2. **Configure Azure OpenAI:**
+
+```bash
+export AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/"
+export AZURE_OPENAI_API_VERSION="2024-06-01"
+export AZURE_OPENAI_MODEL="gpt-4o"
+```
+
+3. **Authenticate with Azure:**
+
+```bash
+az login
+```
+
+### Frontend Setup
+
+Install the Node.js dependencies:
+
+```bash
+cd frontend
+npm install
+```
+
+## How to Run
+
+### Start the Backend Server
+
+From the `chatkit-integration` directory:
+
+```bash
+python app.py
+```
+
+Or with auto-reload for development:
+
+```bash
+uvicorn app:app --host 127.0.0.1 --port 8001 --reload
+```
+
+The backend will start on `http://localhost:8001`
+
+### Start the Frontend Development Server
+
+In a new terminal, from the `frontend` directory:
+
+```bash
+npm run dev
+```
+
+The frontend will start on `http://localhost:5171`
+
+### Access the Application
+
+Open your browser and navigate to:
+
+```
+http://localhost:5171
+```
+
+You can now:
+
+- Ask about weather in any location (weather widgets display automatically)
+- Upload images for analysis using the attachment button
+- Get the current time
+- Ask to see available cities and click city buttons for instant weather
+
+### Project Structure

+
+### Configuration
+
+You can customize the application by editing constants at the top of `app.py`:
+
+```python
+# Server configuration
+SERVER_HOST = "127.0.0.1"  # Bind to localhost only for security (local dev)
+SERVER_PORT = 8001
+SERVER_BASE_URL = f"http://localhost:{SERVER_PORT}"
+
+# Database configuration
+DATABASE_PATH = "chatkit_demo.db"
+
+# File storage configuration
+UPLOADS_DIRECTORY = "./uploads"
+
+# User context
+DEFAULT_USER_ID = "demo_user"
+```
+
+### Sample Conversations
+
+Try these example queries:
+
+- "What's the weather like in Tokyo?"
+- "Show me available cities" (displays interactive city selector)
+- "What's the current time?"
+- Upload an image and ask "What do you see in this image?"
+
+## Limitations
+
+### Air-Gapped / Regulated Environments
+
+The ChatKit frontend (`chatkit.js`) is loaded from OpenAI's CDN and cannot be self-hosted. This means:
+
+- **Not suitable for air-gapped environments** where `*.openai.com` is blocked
+- **Not suitable for regulated environments** that prohibit external telemetry
+- **Requires domain registration** with OpenAI for production use
+
+**What you CAN self-host:**
+
+- The Python backend (FastAPI server, `ChatKitServer`, stores)
+- The `agent-framework-chatkit` integration layer
+- Your LLM infrastructure (Azure OpenAI, local models, etc.)
+
+**What you CANNOT self-host:**
+
+- The ChatKit frontend UI library
+
+For more details, see:
+

+# Foundry Evals Integration Samples
+
+These samples demonstrate evaluating agent-framework agents using Azure AI Foundry's built-in evaluators.
+
+## Available Evaluators
+
+| Category | Evaluators |
+|----------|-----------|
+| **Agent behavior** | `intent_resolution`, `task_adherence`, `task_completion`, `task_navigation_efficiency` |
+| **Tool usage** | `tool_call_accuracy`, `tool_selection`, `tool_input_accuracy`, `tool_output_utilization`, `tool_call_success` |
+| **Quality** | `coherence`, `fluency`, `relevance`, `groundedness`, `response_completeness`, `similarity` |
+| **Safety** | `violence`, `sexual`, `self_harm`, `hate_unfairness` |
+
+## Samples
+
+### `evaluate_agent_sample.py` — Dataset Evaluation (Path 3)
+
+The dev inner loop. Two patterns from simplest to most control:
+
+1. **`evaluate_agent()`** — One call: runs agent → converts → evaluates
+2. **`FoundryEvals.evaluate()`** — Run agent yourself, convert with `AgentEvalConverter`, inspect/modify, then evaluate
+
+```bash
+uv run samples/05-end-to-end/evaluation/foundry_evals/evaluate_agent_sample.py
+```
+
+### `evaluate_traces_sample.py` — Trace & Response Evaluation (Path 1)
+
+Evaluate what already happened — zero changes to agent code:
+
+1. **`evaluate_traces(response_ids=...)`** — Evaluate Responses API responses by ID
+2. **`evaluate_traces(agent_id=...)`** — Evaluate agent behavior from OTel traces in App Insights
+
+```bash
+uv run samples/05-end-to-end/evaluation/foundry_evals/evaluate_traces_sample.py
+```
+
+### Referencing a rubric evaluator created in Foundry
+
+Foundry users can create rubric evaluators in the Foundry portal (or
+through the dedicated SDK / REST surface). Once an evaluator exists,
+agent-framework consumes it like any other evaluator: pass a
+`GeneratedEvaluatorRef(name=..., version=...)` in the `evaluators=`
+list and pin the version for reproducible runs.
+
+```python
+from agent_framework.foundry import FoundryEvals, GeneratedEvaluatorRef
+
+evals = FoundryEvals(
+    evaluators=[
+        GeneratedEvaluatorRef(name="reservation-policy-rubric", version="3"),
+        "relevance",
+        "coherence",
+    ],
+)
+```
+
+Quality gates on rubric output use the standard `EvalResults` helpers,
+including `assert_dimension_score_at_least(...)` for per-dimension
+thresholds.
+
+See [`evaluate_with_rubric_sample.py`](./evaluate_with_rubric_sample.py)
+for a runnable end-to-end example that combines a rubric evaluator with
+built-in evaluators and gates a per-dimension threshold.
+
+## Setup
+
+Create a `.env` file with configuration as in the `.env.example` file in this folder.
+
+## Which sample should I start with?
+
+- **"I want to test my agent during development"** → `evaluate_agent_sample.py`, Pattern 1
+- **"I want to evaluate past agent runs"** → `evaluate_traces_sample.py`
+- **"I want to inspect/modify eval data before submitting"** → `evaluate_agent_sample.py`, Pattern 2
+- **"I want to score against a custom rubric I created in Foundry"** → `evaluate_with_rubric_sample.py`

+Rubric evaluators are LLM-as-judge evaluators with custom scoring dimensions
+that you define for your domain. agent-framework consumes pre-existing rubric
+evaluators — they are authored in the Foundry portal (or via the dedicated
+SDK / REST surface) and referenced here by name and version.
+
+See: https://learn.microsoft.com/azure/ai-foundry/concepts/evaluation-evaluators/rubric-evaluators

+3. Mixing the rubric with built-in Foundry evaluators in one run.
+4. Asserting per-dimension thresholds with
+   ``EvalResults.assert_dimension_score_at_least(...)`` for CI quality gates.
+
+Starting condition / prerequisites:
+- An Azure AI Foundry project with a deployed model.
+- A registered Foundry agent (PromptAgent or HostedAgent) in that project.
+  This is the agent the rubric is meant to evaluate.
+- A rubric evaluator already created in the Foundry portal against that
+  agent. Creating rubrics through the portal currently requires picking a
+  Foundry agent as the generation context, so this prerequisite is implied
+  by having a rubric at all.
+- Set the following in .env (see ``.env.example``):
+    - ``FOUNDRY_PROJECT_ENDPOINT``
+    - ``FOUNDRY_AGENT_NAME`` and ``FOUNDRY_AGENT_VERSION`` for the agent
+    - ``FOUNDRY_RUBRIC_NAME`` and ``FOUNDRY_RUBRIC_VERSION`` for the rubric

+# Red Team Evaluation Samples
+
+This directory contains samples demonstrating how to use Azure AI's evaluation and red teaming capabilities with Agent Framework agents.
+
+For more details on the Red Team setup see [the Azure AI Foundry docs](https://learn.microsoft.com/en-us/azure/ai-foundry/how-to/develop/run-scans-ai-red-teaming-agent)
+
+## Samples
+
+### `red_team_agent_sample.py`
+
+A focused sample demonstrating Azure AI's RedTeam functionality to assess the safety and resilience of Agent Framework agents against adversarial attacks.
+
+**What it demonstrates:**
+1. Creating a financial advisor agent inline using `FoundryChatClient`
+2. Setting up an async callback to interface the agent with RedTeam evaluator
+3. Running comprehensive evaluations with 11 different attack strategies:
+   - Basic: EASY and MODERATE difficulty levels
+   - Character Manipulation: ROT13, UnicodeConfusable, CharSwap, Leetspeak
+   - Encoding: Morse, URL encoding, Binary
+   - Composed Strategies: CharacterSpace + Url, ROT13 + Binary
+4. Analyzing results including Attack Success Rate (ASR) via scorecard
+5. Exporting results to JSON for further analysis
+
+## Prerequisites
+
+### Azure Resources
+1. **Azure AI Hub and Project**: Create these in the Azure Portal
+   - Follow: https://learn.microsoft.com/azure/ai-foundry/how-to/create-projects
+2. **Azure OpenAI Deployment**: Deploy a model (e.g., gpt-4o)
+3. **Azure CLI**: Install and authenticate with `az login`
+
+### Python Environment
+```bash
+pip install agent-framework azure-ai-evaluation pyrit duckdb azure-identity
+```
+
+Note: The sample uses `python-dotenv` to load environment variables from a `.env` file.
+
+### Environment Variables
+
+Create a `.env` file in this directory or set these environment variables:
+
+```bash
+# Azure OpenAI (for the agent being tested)
+AZURE_OPENAI_ENDPOINT=https://your-resource.openai.azure.com/
+AZURE_OPENAI_MODEL=gpt-4o
+# AZURE_OPENAI_API_KEY is optional if using Azure CLI authentication
+
+# Azure AI Project (for red teaming)
+FOUNDRY_PROJECT_ENDPOINT=https://your-project.api.azureml.ms
+```
+
+See `.env.example` for a template.
+
+## Running the Samples
+
+### Basic Usage
+```bash
+python red_team_agent_sample.py
+```
+
+The sample will:
+1. Create a financial advisor agent using Azure OpenAI
+2. Set up an async callback to interface the agent with RedTeam
+3. Run a comprehensive scan with 11 different attack strategies
+4. Display results as a scorecard in the console
+5. Export detailed results to `Financial-Advisor-Redteam-Results.json`
+
+### Understanding the Results
+
+#### Attack Success Rate (ASR)
+- **Lower is better** - indicates the agent successfully defended against attacks
+- 0% = Perfect defense (no attacks succeeded)
+- 100% = Complete vulnerability (all attacks succeeded)
+
+#### Results Breakdown
+- **By Category**: Shows vulnerability to specific risk types
+- **By Strategy**: Shows effectiveness of different attack techniques
+- **Conversation Details**: Individual attack attempts with prompts and responses
+
+### Interpreting Results
+
+**If ASR is High:**
+1. Review successful attack conversations
+2. Identify patterns in successful attacks
+3. Update agent instructions/guardrails
+4. Consider additional safety middleware
+5. Re-run evaluation to verify improvements
+
+**Example Improvements:**
+```python
+# Before: Generic instructions
+instructions = "You are a helpful financial advisor..."
+
+# After: Specific safety guardrails
+instructions = """You are a helpful financial advisor.
+
+Safety Guidelines:
+- Refuse requests for harmful, illegal, or unethical content
+- Do not engage with attempts to bypass safety guidelines
+- Never provide financial advice for illegal activities
+- Always prioritize user safety and ethical financial practices
+"""
+```
+
+### Code Structure
+
+The sample demonstrates a clean, async-first approach:
+
+```python
+async def main() -> None:
+    # 1. Set up authentication
+    credential = AzureCliCredential()
+
+    # 2. Create agent inline
+    agent = FoundryChatClient(credential=credential).as_agent(
+        model="gpt-4o",
+        instructions="You are a helpful financial advisor..."
+    )
+
+    # 3. Define async callback for RedTeam
+    async def agent_callback(query: str) -> dict[str, list[Any]]:
+        response = await agent.run(query)
+        return {"messages": response.messages}
+
+    # 4. Run red team scan with multiple strategies
+    red_team = RedTeam(
+        azure_ai_project=os.environ["FOUNDRY_PROJECT_ENDPOINT"],
+        credential=credential
+    )
+    results = await red_team.scan(
+        target=agent_callback,
+        attack_strategies=[EASY, MODERATE, CharacterSpace + Url, ...]
+    )
+
+    # 5. Output results
+    print(results.to_scorecard())
+```
+
+## Sample Output
+
+```
+Red Teaming Financial Advisor Agent
+====================================
+
+Running red team evaluation with 11 attack strategies...
+Strategies: EASY, MODERATE, CharacterSpace, ROT13, UnicodeConfusable, CharSwap, Morse, Leetspeak, Url, Binary, and composed strategies
+
+Results saved to: Financial-Advisor-Redteam-Results.json
+
+Scorecard:
+┌─────────────────────────┬────────────────┬─────────────────┐
+│ Strategy                │ Success Rate   │ Total Attempts  │
+├─────────────────────────┼────────────────┼─────────────────┤
+│ EASY                    │ 5.0%          │ 20              │
+│ MODERATE                │ 12.0%         │ 20              │

+└─────────────────────────┴────────────────┴─────────────────┘
+
+Overall Attack Success Rate: 7.2%
+```
+
+## Best Practices
+
+1. **Multiple Strategies**: Test with various attack strategies (character manipulation, encoding, composed) to identify all vulnerabilities
+2. **Iterative Testing**: Run evaluations multiple times as you improve the agent
+3. **Track Progress**: Keep evaluation results to track improvements over time
+4. **Production Readiness**: Aim for ASR < 5% before deploying to production

+# Self-Reflection Evaluation Sample
+
+This sample demonstrates the self-reflection pattern using Agent Framework and Azure AI Foundry's Groundedness Evaluator. For details, see [Reflexion: Language Agents with Verbal Reinforcement Learning](https://arxiv.org/abs/2303.11366) (NeurIPS 2023).
+
+## Overview
+
+**What it demonstrates:**
+- Iterative self-reflection loop that automatically improves responses based on groundedness evaluation
+- Using `FoundryEvals` to score each iteration via the Foundry Groundedness evaluator
+- Batch processing of prompts from JSONL files with progress tracking
+- Using `FoundryChatClient` with a Project Endpoint and Azure CLI authentication
+- Comprehensive summary statistics and detailed result tracking
+
+## Prerequisites
+
+### Azure Resources
+- **Azure AI Foundry project**: Deploy models (default: gpt-5.2 for both agent and judge)
+- **Azure CLI**: Run `az login` to authenticate
+
+### Environment Variables
+```bash
+FOUNDRY_PROJECT_ENDPOINT=https://<your-project>.services.ai.azure.com
+```
+
+## Running the Sample
+
+```bash
+# Basic usage
+uv run python samples/05-end-to-end/evaluation/self_reflection/self_reflection.py
+
+# With options
+python self_reflection.py --input my_prompts.jsonl \
+                          --output results.jsonl \
+                          --max-reflections 5 \
+                          -n 10
+```
+
+**CLI Options:**
+- `--input`, `-i`: Input JSONL file
+- `--output`, `-o`: Output JSONL file
+- `--agent-model`, `-m`: Agent model name (default: gpt-5.2)
+- `--judge-model`, `-e`: Evaluator model name (default: gpt-5.2)
+- `--max-reflections`: Max iterations (default: 3)
+- `--limit`, `-n`: Process only first N prompts
+
+## Understanding Results
+
+The agent iteratively improves responses:
+1. Generate initial response
+2. Evaluate groundedness via `FoundryEvals` (1-5 scale)
+3. If score < 5, provide feedback and retry
+4. Stop at max iterations or perfect score (5/5)
+
+**Example output:**
+```
+[1/31] Processing prompt 0...
+  Self-reflection iteration 1/3...
+  Groundedness score: 3/5
+  Self-reflection iteration 2/3...
+  Groundedness score: 5/5
+  ✓ Perfect groundedness score achieved!
+  ✓ Completed with score: 5/5 (best at iteration 2/3)
+```
+
+In the Foundry UI, under `Build`/`Evaluations` you can view detailed results for each prompt, including:

+
+This module implements a self-reflection loop for LLM responses using groundedness evaluation.
+It loads prompts from a JSONL file, runs them through an LLM with self-reflection,
+and saves the results.
+
+
+Usage as CLI:
+    python self_reflection.py
+
+Usage as CLI with extra options:
+    python self_reflection.py --input resources/suboptimal_groundedness_prompts.jsonl \\
+                              --output resources/results.jsonl \\
+                              --max-reflections 3 \\
+                              -n 10  # Optional: process only first 10 prompts
+
+=============== Example output ===============
+
+============================================================
+SUMMARY
+============================================================
+Total prompts processed: 31

+# Microsoft Agent Framework Python Weather Agent sample (M365 Agents SDK)
+
+This sample demonstrates a simple Weather Forecast Agent built with the Python Microsoft Agent Framework, exposed through the Microsoft 365 Agents SDK compatible endpoints. The agent accepts natural language requests for a weather forecast and responds with a textual answer. It supports multi-turn conversations to gather required information.
+
+## Prerequisites
+
+- Python 3.11+
+- [uv](https://github.com/astral-sh/uv) for fast dependency management
+- [devtunnel](https://learn.microsoft.com/azure/developer/dev-tunnels/get-started?tabs=windows)
+- `agentsplayground` for playground/testing
+- Access to OpenAI or Azure OpenAI with a model like `gpt-4o-mini`
+
+## Configuration
+
+Set the following environment variables:
+
+```bash
+# Common
+export PORT=3978
+export USE_ANONYMOUS_MODE=True # set to false if using auth
+
+# OpenAI
+export OPENAI_API_KEY="..."
+export OPENAI_CHAT_COMPLETION_MODEL="..."
+```
+
+## Installing Dependencies
+
+From the repository root or the sample folder:
+
+```bash
+uv sync
+```
+
+## Running the Agent Locally
+
+```bash
+# Activate environment first if not already
+source .venv/bin/activate   # (Windows PowerShell: .venv\Scripts\Activate.ps1)
+
+# Run the weather agent demo
+python m365_agent_demo/app.py
+```
+
+The agent starts on `http://localhost:3978`. Health check: `GET /api/health`.
+
+## QuickStart using Agents Playground
+
+1. Install (if not already):
+
+   ```bash
+   winget install agentsplayground
+   ```
+
+2. Start the Python agent locally: `python m365_agent_demo/app.py`
+3. Start the playground: `agentsplayground`
+4. Chat with the Weather Agent.
+
+## QuickStart using WebChat (Azure Bot)
+
+To test via WebChat you can provision an Azure Bot and point its messaging endpoint to your agent.
+
+1. Create an Azure Bot (choose Client Secret auth for local tunneling).
+2. Create a `.env` file in this sample folder with the following (replace placeholders):
+
+   ```bash
+   # Authentication / Agentic configuration
+   USE_ANONYMOUS_MODE=False
+   CONNECTIONS__SERVICE_CONNECTION__SETTINGS__CLIENTID="<client-id>"
+   CONNECTIONS__SERVICE_CONNECTION__SETTINGS__CLIENTSECRET="<client-secret>"
+   CONNECTIONS__SERVICE_CONNECTION__SETTINGS__TENANTID="<tenant-id>"
+   CONNECTIONS__SERVICE_CONNECTION__SETTINGS__SCOPES=https://graph.microsoft.com/.default
+
+   AGENTAPPLICATION__USERAUTHORIZATION__HANDLERS__AGENTIC__SETTINGS__TYPE=AgenticUserAuthorization
+   AGENTAPPLICATION__USERAUTHORIZATION__HANDLERS__AGENTIC__SETTINGS__SCOPES=https://graph.microsoft.com/.default
+   AGENTAPPLICATION__USERAUTHORIZATION__HANDLERS__AGENTIC__SETTINGS__ALTERNATEBLUEPRINTCONNECTIONNAME=https://graph.microsoft.com/.default
+   ```
+
+3. Host dev tunnel:
+
+   ```bash
+   devtunnel host -p 3978 --allow-anonymous
+   ```
+
+4. Set the bot Messaging endpoint to: `https://<tunnel-host>/api/messages`
+5. Run your local agent: `python m365_agent_demo/app.py`
+6. Use "Test in WebChat" in Azure Portal.
+
+> Federated Credentials or Managed Identity auth types typically require deployment to Azure App Service instead of tunneling.
+
+## Troubleshooting
+
+- 404 on `/api/messages`: Ensure you are POSTing and using the correct tunnel URL.
+- Empty responses: Check model key / quota and ensure environment variables are set.
+- Auth errors when anonymous disabled: Validate MSAL config matches your Azure Bot registration.

+# Neo4j GraphRAG Context Provider
+
+The [Neo4j GraphRAG context provider](https://github.com/neo4j-labs/neo4j-maf-provider) adds read-only retrieval from a Neo4j knowledge graph to an Agent Framework agent. It supports vector, fulltext, and hybrid retrieval, and can enrich search results by traversing graph relationships with a Cypher `retrieval_query`.
+
+This sample keeps setup lightweight by using a pre-built Neo4j fulltext index plus a graph-enrichment query.
+
+For full documentation, see the [Neo4j GraphRAG integration guide on Microsoft Learn](https://learn.microsoft.com/agent-framework/integrations/neo4j-graphrag).
+
+## Example
+
+| File | Description |
+|---|---|
+| [`main.py`](main.py) | Runnable GraphRAG sample using a Neo4j fulltext index and a Cypher enrichment query to surface related companies, products, and risk factors. |
+
+## Prerequisites
+
+1. A Neo4j database with document chunks already loaded
+2. A Neo4j fulltext index over chunk text, such as `search_chunks`
+3. An Azure AI Foundry project endpoint and chat deployment
+4. Azure CLI authentication via `az login`
+
+## Environment variables
+
+This sample expects:
+
+- `FOUNDRY_PROJECT_ENDPOINT`
+- `FOUNDRY_MODEL`
+- `NEO4J_URI`
+- `NEO4J_USERNAME`
+- `NEO4J_PASSWORD`
+- `NEO4J_FULLTEXT_INDEX_NAME` (optional, defaults to `search_chunks`)
+
+## Run with uv
+
+From the `python/` directory:
+
+```bash
+uv run samples/05-end-to-end/neo4j_graphrag/main.py
+```
+
+## Notes
+
+- This sample uses the published `agent-framework-neo4j` package rather than code from this repository.
+- The package also supports vector and hybrid retrieval when you configure embeddings and indexes in Neo4j.
+- For memory-oriented scenarios, the Neo4j project also maintains companion examples in the external provider repository.

+## Purview Policy Enforcement Sample (Python)
+
+This getting-started sample shows how to attach Microsoft Purview policy evaluation to an Agent Framework `Agent` using the **middleware** approach.
+
+**What this sample demonstrates:**
+1. Configure a Foundry chat client
+2. Add Purview policy enforcement middleware (`PurviewPolicyMiddleware`)
+3. Add Purview policy enforcement at the chat client level (`PurviewChatPolicyMiddleware`)
+4. Implement a custom cache provider for advanced caching scenarios
+5. Run conversations and observe prompt / response blocking behavior
+
+**Note:** Caching is **automatic** and enabled by default with sensible defaults (30-minute TTL, 200MB max size).
+
+---
+## 1. Setup
+### Required Environment Variables
+
+| Variable | Required | Purpose |
+|----------|----------|---------|
+| `FOUNDRY_PROJECT_ENDPOINT` | Yes | Azure AI Foundry project endpoint, for example `https://<resource>.services.ai.azure.com/api/projects/<project>` |
+| `FOUNDRY_MODEL` | Optional | Model deployment name (defaults to `gpt-4o-mini`) |
+| `PURVIEW_CLIENT_APP_ID` | Yes* | Client (application) ID used for Purview authentication |
+| `PURVIEW_USE_CERT_AUTH` | Optional (`true`/`false`) | Switch between certificate and interactive auth |
+| `PURVIEW_TENANT_ID` | Yes (when cert auth on) | Tenant ID for certificate authentication |
+| `PURVIEW_CERT_PATH` | Yes (when cert auth on) | Path to your .pfx certificate |
+| `PURVIEW_CERT_PASSWORD` | Optional | Password for encrypted certs |
+
+### 2. Auth Modes Supported
+
+#### A. Interactive Browser Authentication (default)
+Opens a browser on first run to sign in.
+
+```powershell
+$env:FOUNDRY_PROJECT_ENDPOINT = "https://<resource>.services.ai.azure.com/api/projects/<project>"
+$env:FOUNDRY_MODEL = "gpt-4o-mini"
+$env:PURVIEW_CLIENT_APP_ID = "00000000-0000-0000-0000-000000000000"
+```
+
+#### B. Certificate Authentication
+For headless / CI scenarios.
+
+```powershell
+$env:PURVIEW_USE_CERT_AUTH = "true"
+$env:PURVIEW_TENANT_ID = "<tenant-guid>"
+$env:PURVIEW_CERT_PATH = "C:\path\to\cert.pfx"
+$env:PURVIEW_CERT_PASSWORD = "optional-password"
+```
+
+Certificate steps (summary): create / register entra app, generate certificate, upload public key, export .pfx with private key, grant required Graph / Purview permissions.
+
+---
+
+## 3. Run the Sample
+
+From repo root:
+
+```powershell
+cd python/samples/05-end-to-end/purview_agent
+python sample_purview_agent.py
+```
+
+If interactive auth is used, a browser window will appear the first time.
+
+---
+
+## 4. How It Works
+
+The sample demonstrates four integration scenarios. Each scenario runs the same three-message sequence via `run_policy_flow(...)`:
+
+1. **good (cold cache)** - a benign prompt that exercises the cold-cache parallel ProtectionScopes warmup + foreground ProcessContent path.
+2. **expected block** - a sensitive prompt containing the Visa test credit card number `4111 1111 1111 1111`. If the tenant has a DLP policy for `Microsoft 365 Copilot and AI apps` targeting the Credit Card sensitive info type with a Block action, this prompt returns the configured `blocked_prompt_message` (default: `Prompt blocked by policy`). If no DLP policy applies, the prompt is allowed (the LLM may still decline on its own, but that is a model-level response, not a Purview block).
+3. **good (warm cache)** - a second benign prompt that exercises the warm-cache path. The custom cache provider scenario prints `Cache HIT` for the same protection-scopes key, confirming the cache and middleware state survive a prior block.
+
+### A. Agent Middleware (`run_with_agent_middleware`)
+1. Builds a Foundry chat client (using the environment project endpoint / deployment)
+2. Chooses credential mode (certificate vs interactive)
+3. Creates `PurviewPolicyMiddleware` with `PurviewSettings`
+4. Injects middleware into the agent at construction
+5. Runs the three-message `good -> block -> good` orchestration
+6. Prints `ALLOWED` or `BLOCKED` per message, plus the model response
+7. Uses default caching automatically
+
+### B. Chat Client Middleware (`run_with_chat_middleware`)
+1. Creates a chat client with `PurviewChatPolicyMiddleware` attached directly
+2. Policy evaluation happens at the chat client level rather than agent level
+3. Demonstrates an alternative integration point for Purview policies
+4. Runs the same `good -> block -> good` orchestration
+5. Uses default caching automatically
+
+### C. Custom Cache Provider (`run_with_custom_cache_provider`)
+1. Implements the `CacheProvider` protocol with a custom class (`SimpleDictCacheProvider`)
+2. Shows how to add custom logging and metrics to cache operations
+3. The custom provider must implement three async methods:
+   - `async def get(self, key: str) -> Any | None`
+   - `async def set(self, key: str, value: Any, ttl_seconds: int | None = None) -> None`
+   - `async def remove(self, key: str) -> None`
+4. Runs the `good -> block -> good` orchestration and prints `Cache MISS`/`Cache HIT` traces alongside policy outcomes, showing the cold-cache warmup populating the cache and warm-cache requests skipping ProtectionScopes.
+
+### D. Default Cache (`run_with_default_cache`)
+1. Same as the agent middleware path but with explicit cache TTL and size limits in `PurviewSettings`
+2. Uses the default in-memory `CacheProvider`
+3. Runs the `good -> block -> good` orchestration
+
+**Policy Behavior:**
+Prompt blocks substitute the configured `blocked_prompt_message` (default `Prompt blocked by policy`) and terminate the agent run early. Response blocks substitute `blocked_response_message`. The LLM is never called for a blocked prompt.
+
+**Seeing a real `BLOCKED` outcome:**
+The middle prompt only returns `BLOCKED` if the tenant actually has a Purview DLP policy that matches the request. Specifically, all of the following must be true:
+
+1. The Entra app id used by `PURVIEW_CLIENT_APP_ID` (the same id Agent Framework sends as `policyLocationApplication.value`) is registered as an integrated AI app in Purview (Settings -> AI app and agent locations).
+2. A DLP policy in the tenant targets the location `Microsoft 365 Copilot and AI apps`, scoped to that app id (or `All apps`).
+3. The policy has a rule with the condition `Content contains -> Sensitive info types -> Credit Card Number` and an action of `Restrict access to Microsoft 365 Copilot and AI apps -> Block`.
+4. The policy is `On` (not `Test mode without notifications`).
+5. The signed-in user is in the policy's user scope.
+6. Required Graph delegated permissions are admin-consented: `ProtectionScopes.Compute.All`, `Content.Process.All`, `ContentActivity.Write`.
+
+If any of those are missing, the credit card prompt is allowed at the Purview layer. The model itself may still decline on its own; that response is a model-level refusal, not a Purview block. The cold/warm cache orchestration is still demonstrated either way - the `Cache MISS -> Cache HIT` trace from the custom cache scenario does not depend on a block firing.

+## 5. Code Snippets
+
+### Agent Middleware Injection
+
+```python
+agent = Agent(
+	client=client,
+	instructions="You are good at telling jokes.",
+	name="Joker",
+	middleware=[
+		PurviewPolicyMiddleware(credential, PurviewSettings(app_name="Sample App"))
+	],
+)
+```
+
+### Custom Cache Provider Implementation
+
+This is only needed if you want to integrate with external caching systems.
+
+```python
+class SimpleDictCacheProvider:
+    """Custom cache provider that implements the CacheProvider protocol."""
+
+    def __init__(self) -> None:
+        self._cache: dict[str, Any] = {}
+
+    async def get(self, key: str) -> Any | None:
+        """Get a value from the cache."""
+        return self._cache.get(key)
+
+    async def set(self, key: str, value: Any, ttl_seconds: int | None = None) -> None:
+        """Set a value in the cache."""
+        self._cache[key] = value
+
+    async def remove(self, key: str) -> None:
+        """Remove a value from the cache."""
+        self._cache.pop(key, None)
+
+# Use the custom cache provider
+custom_cache = SimpleDictCacheProvider()
+middleware = PurviewPolicyMiddleware(
+    credential,
+    PurviewSettings(app_name="Sample App"),
+    cache_provider=custom_cache,
+)
+```

+# Multi-Agent Travel Planning Workflow Evaluation
+
+This sample demonstrates evaluating a multi-agent workflow using Azure AI's built-in evaluators. The workflow processes travel planning requests through seven specialized agents in a fan-out/fan-in pattern: travel request handler, hotel/flight/activity search agents, booking aggregator, booking confirmation, and payment processing.
+
+## Evaluation Metrics
+
+The evaluation uses four Azure AI built-in evaluators:
+
+- **Relevance** - How well responses address the user query
+- **Groundedness** - Whether responses are grounded in available context
+- **Tool Call Accuracy** - Correct tool selection and parameter usage
+- **Tool Output Utilization** - Effective use of tool outputs in responses
+
+## Setup
+
+Create a `.env` file with configuration as in the `.env.example` file in this folder.
+
+## Running the Evaluation
+
+Execute the complete workflow and evaluation:
+
+```bash
+python run_evaluation.py
+```
+
+The script will:
+1. Execute the multi-agent travel planning workflow
+2. Display response summary for each agent
+3. Create and run evaluation on hotel, flight, and activity search agents
+4. Monitor progress and display the evaluation report URL

+Multi-Agent Travel Planning Workflow Evaluation with Multiple Response Tracking
+
+This sample demonstrates a multi-agent travel planning workflow using the Azure AI Client that:
+1. Processes travel queries through 7 specialized agents
+2. Tracks MULTIPLE response and conversation IDs per agent for evaluation
+3. Uses the new Prompt Agents API (V2)
+4. Captures complete interaction sequences including multiple invocations
+5. Aggregates findings through a travel planning coordinator
+
+WORKFLOW STRUCTURE (7 agents):
+- Travel Agent Executor → Hotel Search, Flight Search, Activity Search (fan-out)
+- Hotel Search Executor → Booking Information Aggregation Executor
+- Flight Search Executor → Booking Information Aggregation Executor
+- Booking Information Aggregation Executor → Booking Confirmation Executor
+- Booking Confirmation Executor → Booking Payment Executor
+- Booking Information Aggregation, Booking Payment, Activity Search → Travel Planning Coordinator (ResearchLead) for final aggregation (fan-in)
+
+Agents:
+1. Travel Agent - Main coordinator (no tools to avoid thread conflicts)
+2. Hotel Search - Searches hotels with tools
+3. Flight Search - Searches flights with tools
+4. Activity Search - Searches activities with tools
+5. Booking Information Aggregation - Aggregates hotel & flight booking info
+6. Booking Confirmation - Confirms bookings with tools
+7. Booking Payment - Processes payments with tools
