## AI 摘要

Elvis Saravia 建议开发者自建并掌控 agent harness，即使最小化 harness 也能带来更好的代码、输出、成本和写作效果，并称 Pi 正因此获得大量采用。他推荐关注 Eve、Exo、Prime Agent 等开源项目。Uncle Bob 则反思，其花数周构建的严格约束 harness 在 agents 大幅变强后已无必要。

Build and own your harness, folks.

Very few people understand the magic behind customizing and optimizing an agent harness for your work.

You can start seeing incredible results quickly, even with a minimal harness. Just better code, better outputs, better costs, better writing, and so on.

As an example, I see way too many people complain that they are tired of their out-of-the-box agent harness producing verbose outputs. If you built a harness, that's easier to fix with a system prompt optimized for you.

This is why Pi is getting insane adoption these days. You want to control your harness. I agree that it's hard to optimize where things stand, but self-improving algorithms will make it easier to learn from trajectories. And if you use local models, you can tune all of that end-to-end (through a co-evolution of the harness and the models) as you work with them.

Look into open-source projects like Eve, Exo, and Prime Agent, and you will see what I mean.
