The settings plugin list projected ctx.loader.entries() alone, hiding the plugins sessions actually run and rendering the web overlay's deliberate disabled tombstones (tool-bash, tool-fs, ...) as two dozen plainly disabled rows while the same modules ran in every standard-preset session. - dsh-agent-presets: compositionInventory() answers flattened rows per preset — newest live standing generation when mounted, composition file otherwise with !!js disabled gates evaluated against the Loader context; reading never mounts (regression-tested), refusal stays 'conditional', raced files report broken with the reason. - dsh-host-plugin-inventory: list() gains an optional agentPresets block, resolving the roster as an optional peer and mapping fiber states to the public phase vocabulary. - ui-settings-plugin-inventory: preset group first behind a display-only switcher opening on the default preset; global group collapsed with failures floated; host-disabled modules enabled by >=1 preset fold into a session-plugins drawer naming providers; search spans scopes and points at matches in unselected presets. - ui-agent-preset: the General-settings default-preset row is deleted — the roster section's make-default and the new-session chip keep the field — and the settings store slims to the display roster the header label reads. Docs, catalogs, module graph, settings-chrome goldens, and the bilingual Agent Note ride along.
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.
