Guide to building a Jev harness, claimed 200x faster and 400x cheaper
A guide on building a Jev harness argues the bottleneck is agent routing, tools and context rather than the model, and can be fed to Claude Code or Codex to rebuild.
this is gold for anyone building coding agents. Someone wrote a guide to building a Jev harness. the promise: → 200x faster → 400x cheaper and the best part? you don't need a better model. the bottleneck is often the harness around it: how your agent routes tasks, uses tools, manages context, and decides what deserves a full LLM call. here's how to try it: → grab the PDF and the accompanying article → drop both into Claude Code or Codex → ask it to rebuild its own harness based on the guide one evening of setup could give your coding agent a serious upgrade. same model. smarter harness. less waiting, lower bills. most teams are still trying to solve every problem by switching models. start by fixing the system around them. https://x.com/Mr_Buzzoni/status/2111705083826110787/video/1
