* feat(web): boot past failed optional client plugins The Web client boot audit now follows Host startup strictness. An inactive entry on the global required list (module system, Session transport, renderer, application frame, Session view, and sidebar) still rejects startup and the report marks the required entries. Other inactive entries produce one console warning and the application mounts without them. The boot page no longer draws a failed entry before the audit decides. * fix(web): audit boot entries whose creation rejects and name activation errors ClientEntries.start() now logs a row whose Loader creation rejects, such as a module that exports no plugin, and leaves it inactive for the boot audit, as the Host Loader group does. The audit awaits only failed fibers to report their recorded activation error. Notes, READMEs, and the Web client subsystem page describe the browser boot audit; tests cover invalid exports, carrier presentation of optional failures, and required names absent from the boot graph. * test(web): fail test carriers and e2e on inactive client entries The product boot only warns about inactive entries outside its required list, but tests must still surface every plugin that fails. TestClient and createClientTest now require every roster entry to activate unless a case passes allowInactiveEntries. The watchConsole tripwire, the real-host smoke, and the assembled jsdom boot treat a web boot warning as a failure with no opt-out. Docs: the Web README names Session control, notes that an entry without a fiber is reported as an import failure like the Host audit's "failed to import", and the startup strictness note lists the browser tests.
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.
