The authors build a taxonomy where each act is a verb (e.g., Request, Propose, Amend, Commit, Deliver) paired with a noun describing its object (e.g., information, meeting, task). 2. **[Are My Optimized Prompts Compromised? Exploring Vulnerabilities of LLM-based Optimizers](https://md.research.elamur.ai/free/en/papers/zhao-2026-are-my-optimized-prompts-compromised/)** *(2026)* LLM-based prompt optimizers rewrite a system prompt over many rounds, guided by scored feedback on the model's answers. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Learning to Classify Email into “Speech Acts”](https://md.research.elamur.ai/free/en/papers/cohen-2004-learning-classify-email-into-speech/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**William W.
