Self-improving harness frameworks for AI agents

A discussion of self-improving harness frameworks for AI engineering. - The core idea is that harness engineering is becoming a major focus as teams build more capable agent systems. - New frameworks let agents write parts of their own execution logic and optimize how they operate. - The reply argues that general-purpose harnesses are useful for exploration and one-off tasks. - As an AI application matures, its rules become more fixed, and the prompts, models, tools, and skills used for each task become more specialized. - At that stage, it becomes worthwhile to design a custom harness tuned to that specific application. - The main tradeoff is that harness engineering is difficult, but it can unlock better performance and maintainability.
