A coworker was trying to tell me that models perform better in their own agent harnesses. I use both `pi` and `omp` and I'm somewhat skeptical. I understand that the tool calls might be slightly different. But really how much impact on the model itself does the harness have?
I think it's often the other way around. The differences in perceived coding productivity that many people attribute to claude vs codex is more the harness than the model it's running (if running comparable classes of models).
What is the harness doing that's not the model.
I've been assuming a harness is basically a set of tools and a TUI for passing text to the model and the model coming back with tool calls and user responses.
Are the tools really that complex and different between harnesses?
