Agent presets: every card that composes carries a gear that opens the preset's detail page (breadcrumb, name, marks, description) and declares a `settings.agentPreset.detail` slot for the sections other plugins contribute. Plugin manager: the session-plugins group leaves the tab for the detail page's Capabilities section, with a red Delete on rows the person added and an Add menu over the installed modules the preset lacks; the manage tab now precedes the configuration tab. Plugin configuration: the scope switch is gone. The tab edits the values shared by all presets, and the same cards form the detail page's Settings section, registered under a second keyed slot (`settings.agentPreset.plugin.item`) and editing the preset's own scope while the page is open. The roster dependency the switch needed leaves with it. Web e2e goldens, both READMEs of each package, the Agent Note, the slot catalog, and the inspect catalog follow.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
