DeepSeek Harness: A Plugin-Centric Runtime for AI Agents
DeepSeek Harness (dsh) is an open-source agent harness from DeepSeek AI with a plugin-everything architecture powered by Cordis, a framework designed around spatiotemporal composability. It is currently in developer preview, so breaking changes are expected. You can run it from npm or from source, and it launches a local Web UI at 127.0.0.1:3080 by default. The project aims to be a modular runtime for building and operating AI agents, and is suited for engineers who want an extensible, self-hosted agent infrastructure rather than a closed product. Community support is available via GitHub Discussions and Discord, and plugins can use the 'dsh-plugin' topic for discoverability.
