A lot of people are starting to talk about Harness Engineering in AI.

But what does it actually mean?

As models become more capable, improving an AI system is no longer only about writing a better prompt or switching to a better model. A huge part of the performance comes from everything we build around the model.

That surrounding system is the harness.

Think about a coding agent. The model may be capable of writing good code, but it still needs access to the repository, tools to search and edit files, a way to run tests, feedback from those tests, context about previous actions, and rules
