Jev harness 构建指南：号称快 200 倍、省 400 倍
一份讲如何围绕 Jev 重搭 agent 工作流的 playbook，附三步落地法：重建配置、挑最贵流程、对比前后成本。
This is a playbook worth studying if you’re building with coding agents. A guide to building a Jev harness breaks down how the right setup can deliver: → Up to 200x faster execution → Up to 400x lower costs The model isn’t always the bottleneck. The harness around it can make a massive difference in both speed and cost. Here’s how to put this into practice: 1. Rebuild your setup Give the PDF and the article below to Claude Code or Codex. Ask it to redesign your agent workflow around Jev. 2. Pick your most expensive workflow Find the agent task your team spends the most money running. Try rebuilding it in one evening. 3. Show the results Compare the before-and-after latency, token usage, and cost. Bring the numbers to your manager. One evening of harness engineering could save your team a serious amount of money and give you a system most teams haven’t even thought to build. https://x.com/AnnatarXBT/status/2108868206358085779/video/1
