Move `load_workspace_dependencies` and the primary-runtime payload logic out of `apps/desktop-host` into `@deepseek-ai/dsh-tool-workspace-dependencies` so profiles other than Desktop can mount the same tool. Desktop keeps its behavior through the package. Two additions for carriers that are not Electron applications: - `root` is optional: without it the payload is validated and used in place (no copy under the Harness home), which suits read-only container layers. - `runtime.json` accepts `linux`, and the `node` / `pnpm` components are optional; the returned paths and the tool output omit what the payload does not ship. The `sdk` profile mounts the tool and `@deepseek-ai/dsh-skill-office` when `DSH_PRIMARY_RUNTIME` names a payload directory (its sibling `office-skills/` carries the skill resources); both rows stay disabled otherwise. Both packages join the Python runtime closure.
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.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
