Bring master 45d1196d3fe into the release/dsh-0.2.1 squash commit of #6247 so the release commit stays an ancestor of master. Conflict resolutions: - apps/web/tsconfig.json, tsconfig.host.json: keep the entry-customization e2e and master's Computer Use e2e entries. - docs/subsystems/slots.{md,zh.md}: keep both added paragraphs; re-record the slots, ui-primitives, and ui-workspace README translation pairs. - ui-sidebar SidebarRoot.tsx and locales.ts: keep the More menu imports and copy next to master's version-copy toast. - apps/web/tests/agent-preset-selection.e2e.ts: keep the New Session blank-reuse assertions, read presets through master's sessionProjections.checkpoint() instead of the deprecated stateOf(). Follow-ups on master's side: - ui-sidebar sidebar-root spec: give master's version-copy render the entry pin props that SidebarRootInjected now requires. - snapshots/web/steering/trajectory.expected.md: add the More conversation views trigger to master's new Trajectory golden.
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.
Contributing
See CONTRIBUTING.md.
Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
