# DeepSeek Harness

An open-source agent harness from DeepSeek AI built on a plugin-based architecture, with a local web UI started from npm. It is in developer preview.

DeepSeek Harness (dsh) is an agent harness developed by DeepSeek AI. Its architecture treats everything as a plugin and is powered by Cordis, a framework described in the paper A Programming Paradigm for Spatiotemporal Composability.

Running it with npx starts a web UI on a local port, and it can also be built and run from source with pnpm. Plugin authors can tag their repositories with the dsh-plugin topic for discovery.

The project is in developer preview and warns that compatibility-breaking changes will happen. It is written in TypeScript and MIT licensed.
