        ## 🔬 How the Agentic AI Works
        
        1. **🎯 Criteria Interpretation**: AI analyzes your natural language task and defines measurable success conditions
        2. **🔧 Intelligent Design**: LLM proposes vehicle specifications based on physics principles and your requirements  
        3. **⚗️ Physics Simulation**: Each design is tested in accurate PyBullet physics simulation with real obstacles
        4. **📊 Performance Analysis**: Results are evaluated against your interpreted criteria with detailed metrics
        5. **🔄 Iterative Learning**: AI uses simulation feedback to refine and improve designs automatically
        6. **🏆 Best Design Selection**: System tracks performance and presents the optimal solution found
        
        **🚀 Innovation**: This demonstrates autonomous AI that goes beyond text generation - it's an agent that designs, tests, learns, and optimizes physical systems to meet user-defined functional requirements.
