DeepSeek Harness

DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI that uses a plugin-based architecture powered by Cordis for spatiotemporal composability. Currently in developer preview with rapid iterations and compatibility-breaking changes expected, users can run it via npm or from source, with a web UI accessible at http://127.0.0.1:3080 by default. The project welcomes community feedback and bug reports through GitHub Discussions.
