Deep Seek Harness (dsh) is an open‑source agent harness created by DeepSeek AI. It follows a plugin‑centric architecture where every component is a plugin, powered by Cordis, a design described in *A Programming Paradigm for Spatiotemporal Composability*. The project is currently in developer preview, iterating rapidly, and warns users that compatibility‑breaking changes will occur.

To run the tool, install Node.js and use npm to execute `npx @deepseek-ai/dsh web`. This launches the Web UI at http://127.0.0.1:3080 by default; consult the Web UI guide for details. For a full source build, clone the repository, `cd deepseek-harness`, run `pnpm install`, then `pnpm run build` followed by `pnpm dsh web`.

Community contributions are welcomed via GitHub Discussions; add the `dsh-plugin` topic to plugin repos for discoverability. Join the DeepSeek Harness Discord community and refer to CONTRIBUTING.md, the development guide, architecture docs, and AGENTS.md for agents. The project is licensed under MIT, with third‑party notices in THIRD_PARTY_NOTICES.md.
