Summary
The blog post explains the concept of an 'agent harness,' which surrounds a language model and facilitates its operation by managing context, executing tools, and applying permissions. It distinguishes between a model, a scaffold, a harness, and an agent while detailing how the engineering behind harnesses impacts their functionality. It highlights that a well-designed harness can significantly enhance the usability and accessibility of a language model, affecting everything from safety to user experience, and that the choice of harness is crucial for developers looking to implement coding agents effectively.
