First Impressions of DeepSeek Harness: Everything Being a Plugin Is Too Cool

DeepSeek Harness was released last Friday. Within a few hours, it was everywhere in AI communities in China and abroad.

I downloaded it right away and tried it. If you only look at the default interface, the first impression is honestly a bit rough. There are not many feature entry points. It does not even have a client yet. The interaction details are not as complete as Codex, Claude Code, or WorkBuddy. Those products have already been polished for a while. You can open them and start working, and many workflows have already been thought through for you. DeepSeek Harness is still in Developer Preview, and the official README directly says that breaking changes may happen.

I just used AI to write a paper review of DeepSeek-V4.

The workflow was smooth. I dropped the PDF in, asked AI to extract the content, organize the structure, generate illustration ideas, and then turn everything into a technical blog post that looked fairly complete. The key innovations and the interpretation of evaluation results were both pretty decent. I put the outline below. It looks quite good, doesn’t it?
