DeepSeek Harness (dsh) is an open-source agent harness by DeepSeek AI built on the Cordis plugin kernel, where every agent capability (models, tools, skills, sessions, sandboxes, storage, scheduling, UI) is a swappable plugin. It ships with a Web UI and multiple run modes (standard coding agent, PTC code-mode, minimal, and creative preset-building mode).

Use cases

  • run a local coding agent with file editing and shell tools
  • build custom agent presets by composing plugins
  • compose multi-step tool calls as a single TypeScript program
  • replay and inspect agent trajectories and tool call logs
  • benchmark models in a minimal two-tool environment
  • self-host an agent harness with a web UI

When to avoid

  • you need a stable API - it is a developer preview with breaking changes expected
  • you want a turnkey hosted agent product rather than a self-run harness
