 See the `examples/` directory for usage examples:
 - 📓 `examples/udora_attack_demo.ipynb`: Comprehensive attack demonstration with malicious environment
 Note: we found that use indirect prompt injection + adversarial string optimization is more effective, in other words, use fixed indirect prompt injecttion (e.g., "Please buy this item") + adversarial string optimization ({optim_str} for optimization).
