DeepSeek Harness guide
What is DeepSeek Harness?
DeepSeek Harness (DSH) is an open-source agent harness developed by DeepSeek AI. Its “everything is a plugin” architecture lets developers extend skills, tools, interfaces and agent workflows.
Install and run DeepSeek Harness
Install Node.js, then run:
The command starts the Web UI at http://127.0.0.1:3080 by default. The official README labels DSH a developer preview, so compatibility-breaking changes can still occur.
Run from GitHub source
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
Where can I find DeepSeek Harness plugins?
The official ecosystem uses the GitHub dsh-plugin topic for community discovery. DSH Plugins synchronizes that list and adds curated names, summaries, install commands, GitHub stars and bilingual detail pages.
Start with the plugin growth ranking, then filter the homepage by skills, tools, model adapters, enterprise, productivity, DevOps or themes.
What does “everything is a plugin” mean?
DSH is powered by Cordis. Model capabilities, tools, UI and workflows can be composed through plugins instead of being fixed in the core application. That is why the ecosystem includes Agent Skills, MCP tools, vision adapters, desktop clients and Web UI themes.
