What is DeepSeek Harness Explained?
deepseek harness (dsh) is an open-source agent runtime that provides a plugin-based architecture for building and running agent workflows.
It uses the Cordis kernel to mount, unmount, and swap plugins that implement models, tools, sandboxes, persistence, and session adapters.
The runtime supplies a workspace, tool registry, sandbox approval policy, append-only session log, and an agent loop that sequences model calls and tool executions.
dsh includes a web UI and a headless runner, a CLI install path (npx @deepseek-ai/dsh web), and serves a local development UI on 127.0.0.1.3080.
Plugins are distributed as bundles and patches, support profile-driven configuration, and enable replacement of adapters for models, storage, and sandboxes.
Target users include developer teams, platform engineers, and plugin authors who need inspectable agent loops, replaceable model adapters, and configurable sandboxes.
Implementation details. TypeScript, Node.js 22.19+/24+, MIT license, repository deepseek-ai/deepseek-harness.
