What harness is the best for local LLMs? I've been researching optimizing local LLM agent harness performance with context/ tools. Quite the endeavor and would love to learn what users prefer for this type of workflow.
I like vibe and pi. Vibe just looks nice and is good enough. But pi extensibility is just another level. There is also Dirac that is quite OK but seems like full of bugs. Zerostack is the simplest harness I saw. OpenCode is OK too. Rest I did not try.
What's the technical reason we call call these a harness? Seems right but want to understand better.
The model represents intelligence and the harness is toolset which allows the model to create more informed decisions with context. Specifically, loops, subagents, tools, connectors, prompts, skills, and much more. This is why Cursor performs so well.
