winewill ee0fc82267 fix(desktop): check the bundled runtime against the product version
Injecting a build version renamed the Electron shell but not the dsh
runtime packed into it, and afterPack required the two to be equal, so
every build carrying a build version failed after packaging finished.
The bundled runtime is the dsh package at the product version, which is
what the check now compares against; the app already reports the shell
version and the bundled runtime version separately to the update policy.

Rename the flag to --build-version. The repository already has
DOWNLOAD_TEST_RELEASE_ID for the opaque test feed directory, so calling
a version a release id invited a reader to confuse the two. Accept a
forwarded `--` as well, because `pnpm run <script> -- --build-version x`
passes the separator through as an argument and every following option
would otherwise parse as a second target.

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

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.
