DeepSeek Harness English | 中文 DeepSeek Harness (`dsh`) is an open-source agent harness developed by DeepSeek AI. It uses an architecture where **everything is a plugin**, and is powered by Cordis, whose design is described in _A Programming Paradigm for Spatiotemporal Composability_. Developer preview DeepSeek Harness is currently in _developer preview_ and is iterating rapidly. **THERE WILL BE COMPATIBILITY-BREAKING CHANGES.** Run Run from `npm` Install `Node.js`, then run: 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: `pnpm run build` prepares the repository artifacts. `pnpm dsh web` uses those built artifacts without rebuilding. Community and support - Feel free to submit feedback or bug reports through GitHub Discussions. - Add the `dsh-plugin` topic to your plugin repository for discoverability. - Join <a href="https://discord.gg/Ycq5dCaS4">DeepSeek Harness Discord community</a>.
