About this site - DeepSeek Harness
The DeepSeek Harness site is an introduction and usage guide for the DeepSeek Harness (dsh) developer preview — a place dedicated to explaining how an agent harness is built with an everything-is-a-plugin architecture.
What this site is
DeepSeek Harness is an open-source agent harness by DeepSeek AI with a plugin-based open architecture. This site does three things around it:
- Product introduction — explains the everything-is-a-plugin design, the four run modes, and traceable sessions
- Usage docs — from a single npx command to the Web UI, architecture, and plugin development
- Community hub — collects the official repository, GitHub Discussions, and the dsh-plugin ecosystem in one place
Our stance
- No repackaging of official code — this site only introduces and points to the official channels
- No hype — content follows the official repository and docs, and preview limitations are stated honestly
- Respect for open source — DeepSeek Harness is MIT licensed; this site's content is free to share with attribution
