这个讲得非常好，推荐大家看一下这个视频。

很多人做 AI 还停在“怎么写 prompt”，但 Agent 真正能开始干活，是从 context、harness 到 loop 这一整套东西接起来：知道什么、能用什么、怎么判断下一步、怎么反复推进。
把这几个概念串起来看，很多 AI 产品的差距就很清楚了。 https://t.co/vrKCKQ5jvc
This is very well said. I recommend everyone to watch this video. Many people working on AI are still stuck on 'how to write prompts', but an Agent can truly start working only when the whole set of things from context, harness, to loop are connected: knowing what, being able to use what, how to judge the next step, how to iteratively advance. By linking these concepts together, the gaps between many AI products become clear.
