AI Engineering Evolves: Harness and Loop Concepts Emerge

By PulseAugur Editorial · [1 sources] ·

The article discusses the evolution of AI engineering terminology, moving beyond prompt and context engineering to include "harness engineering" and "loop engineering" as coined by human developers in 2026. Harness engineering focuses on the deterministic runtime layer surrounding an LLM, managing tool invocation and execution, while loop engineering involves designing autonomous agent loops. The author emphasizes the importance of human oversight and verification in AI development, using personal prototypes like RAPTOR and llloop to illustrate these concepts. AI

IMPACT Introduces new terminology for AI development, emphasizing human-driven design of AI systems.

RANK_REASON The article discusses evolving AI engineering concepts and terminology coined by humans, rather than a new model release or research breakthrough.
