Standard
Daily driverThe full coding agent: file editing, shell access, retrieval, the whole tool table.
Everything in DSH is a plugin.
DeepSeek Harness is the open agent runtime where models, tools, storage and the loop are all swappable plugins.

The model is half the agent
Agent = Model + Harness
The model supplies judgement. The harness supplies everything the judgement acts on: what the agent can see, which tools it may call, where its session is written, and when the loop stops. DSH makes that second half editable.

Cordis kernel Service registry, dependency injection, reversible effects
Each block in the harness row is a plugin you can replace without touching the layer above or below it.
Four presets, one runtime
The same kernel boots into different shapes depending on how much surface area you want the agent to have.
PTC
Code as tool callsTools composed in TypeScript instead of selected one at a time, so a turn can express a whole program.
Minimal

dsh-web-ui
@zhu1090093659
Plugin and skin collection for DeepSeek Harness (DSH) Web UI - task board, git graph, right-side panel, remote mobile UI, pet, live token stats, and skin center.
modlens
@liustack
The first vision plugin for DeepSeek Harness, and the vision bridge for every text-only coding agent. Paste an image, get structured JSON evidence (OCR, layout, semantics).
dsh-TUI
@ccch1mneyyy
A gap-filling project solving the absence of an official TUI for DSH, dedicated to geeks who prefer the CLI: Claude Code style full-screen interactive terminal plugin - pixel-style whale top bar, real-time status line, streaming thought expansion, double-Esc rollback, context progress bar + TPS gauge. One-click npm installation.
sandbase-harness
@sandbaseai
Open-source CMA-compatible agent runtime for any model, with MCP tools, sandboxed sessions, audit, replay, and a local console. Includes a native DeepSeek Harness bundle over stdio MCP.
From nothing to a running agent
-
Install
Node 18 or newer is the only prerequisite. No global install, no account.
-
Add a plugin
Plugins are npm packages. The kernel resolves what each one depends on and boots them in the right order.
-
Inspect
Every service, every tool call and every session write is visible while the agent runs.
Read the source, then change it
DSH is MIT licensed and in developer preview. Breaking changes land often, and the plugin API is where most of them show up.
