Sam Witteveen — 'NEW DeepSeek Harness - Super Agent!'
Sam Witteveen looks at DeepSeek's Super-agent, an open prototype add-on for DeepSeek Harness that takes requests from GitHub conversations, and compares it with agent teams.
Sam Witteveen explains DeepSeek's Super-agent plugin and asks whether the model or the harness matters more.
What is it?
'NEW DeepSeek Harness - Super Agent!' went up on Sam Witteveen's channel on 3 November 2026. The 18-minute video covers DeepSeek's dsh-superagent prototype, an open-source add-on for DeepSeek Harness that DeepSeek published on GitHub on 31 October 2026.
How does it work?
The video starts with a recap of DeepSeek Harness and its design where everything is a plugin, then explains what Super-agent does. Chapters cover whether the model or the harness matters more, a frontier harness benchmark, and how a single Super-agent differs from teams of agents.
Why does it matter?
Witteveen also covers the limits: the project is a prototype, it only works with GitHub, and its tests are synthetic. That helps viewers judge whether DeepSeek's always-on agent design is ready to try on a real repository.
