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
