State of Context Engineering: Drew Breunig maps where the field is heading

Drew Breunig, author of the upcoming O'Reilly "The Context Engineering Handbook," gave an AGNTCon talk serving as a state-of-the-field review of context engineering: its origins, evolution, and future. Key thesis: the job is knowing when to be deterministic vs. probabilistic, and conveying clear, consistent, low-noise instructions to AI remains a permanent challenge. Models aren't people — their construction creates unique failure modes that harness builders must design fixes for. Full slides and transcript on his blog.
