Your new acronym for today is Agentic Context Engineering (ACE), "a framework that treats contexts as evolving playbooks that accumulate, refine, and organize strategies through a modular process of generation, reflection, and curation." As Robert Rogowski summarizes today, "It overcomes two major failures in adaptive LLMs: brevity bias (over-compression of prompts) and context collapse (loss of detail during rewriting)." Indeed, from my observation, a lot of the'AI hallucinations' we read about can be avoided with better prompts. On the other hand, it is arguable that prompt engineering is just a way of smuggling human knowledge into AI systems. Either way, though, it does show that the context of an inquiry has a significant impact on the outcome. 23 page PDF.
