+# integration-tau (Tau Simulated User Example)
+
+You can run this example with:
+
+```bash
+npx promptfoo@latest init --example integration-tau
+cd integration-tau
+```
+
+This example demonstrates testing conversational AI agents using **OpenAI's Responses API with function calling**. It simulates an airline booking system with 31 different customer personas to test how well agents handle realistic conversations.
+
+## How It Works
+
+The example uses **mocked airline functions** to simulate a booking system without requiring real APIs:
+
+- **Agent responds** to customer requests using conversational AI
+- **Functions are called** for operations like searching flights and booking tickets
+- **Mock responses** provide realistic data (user profiles, flight options, confirmations)
+- **31 personas** test different customer behaviors and edge cases
+
+## Quick Start
+
+1. **Set your API key**: `export OPENAI_API_KEY=your_api_key_here`
+2. **Run the evaluation**: `promptfoo eval`
+3. **View results**: `promptfoo view`
+
+## What You'll See
+
+Realistic multi-turn conversations between different customer types and the booking agent:
+
+```text
+User: I need a flight from New York to Seattle on May 20th
+Agent: I'd be happy to help! May I have your user ID?
+User: It's mia_li_3668
+Agent: Thank you! I found these options: Direct flight $325, One-stop $295
+User: I'll take the cheaper United flight
+Agent: Perfect! Your flight is confirmed. Confirmation: CF8X2M1K
+```
+
+## Customer Personas Tested
+
+- **Budget travelers** focused on lowest prices
+- **Business travelers** needing flexibility and speed
+- **Anxious flyers** wanting direct routes and front seats
+- **VIP customers** expecting premium service
+- **Accessibility-focused** travelers with special needs
+
+## Customization
+
+- **Add personas**: Create new customer types with different behaviors
+- **Extend functions**: Add seat selection, loyalty programs, etc.
+- **Test other models**: Compare function calling across AI providers
