From Prompt to Loop: How AI Engineering Evolved in Three Years
The article traces the evolution of AI interaction design from prompt engineering (2022-2024) to context engineering (2025) and now loop engineering (2026). Each shift changed the unit of work: from a single message to the entire context window, and finally to the verification loop. The key insight is that the model is no longer the bottleneck; the verifier that decides when to stop is.

The renaming reflects real shifts in where the engineering effort goes, but the hype cycle risks overselling novelty—the underlying problems of verification and control have been known for years.
