DeepSeek Harness

Active
GitHub TypeScript MIT

Description

Official open-source agent harness from DeepSeek built on an "everything is a plugin" spatiotemporal composability architecture, with a built-in Web UI and a growing plugin ecosystem.

Key Features

  • Everything is a plugin — Cordis-powered plugin architecture where capability units compose and hot-swap freely
  • Spatiotemporal composability — a novel agent programming paradigm described in the accompanying arXiv paper
  • Built-in Web UI — one npx command boots a full visual chat interface on localhost:3080
  • Plugin ecosystem — community plugin repos are published under the dsh-plugin topic for discoverability
  • Official DeepSeek project — MIT-licensed, maintained by DeepSeek AI with safety notes and architecture docs

Use Cases

💡 Assemble DeepSeek models into a local agent application with a web UI using the official harness
💡 Extend tools, memory, and surfaces through plugins to build a custom agent runtime
💡 Study the spatiotemporal composability paradigm as an architectural reference for your own agent framework
💡 Deploy a pluggable agent foundation on-prem and layer business plugins on demand

Strengths & Limitations

✅ Strengths

  • • Actively maintained, recent updates
  • • High community interest (210.0k stars)
  • • Permissive open-source license (MIT)
  • • Responsive to issues, low backlog
