managing agents\n3. **BuyerAgent**: Handles product inquiries, quote evaluation, and negotiation\n4. **SellerAgent**: Manages inventory, quote generation, and order fulfillment\n5. **Message Routing**: Proper ACP message handling with Zod validation\n6. **Negotiation Logic**: Multi-round negotiation capabilities\n7. **Status Tracking**: Comprehensive monitoring of agent activities\n\nThe system follows the marketplace choreography pattern with proper message validation, error handling, and trilingual documentation."
