DeepSeek Harness: Everything is a Plugin.
Install Deepseek Harness
Installs but activates nothing: package.json has no `dsh.bundle` declaration, so `dsh plugin` warns and loads no config layer.
This repository is not a DSH plugin
package.json declares no dsh.bundle. In the official docs' own words, a package like this “still installs, but only as a plain dependency: dsh plugin prints a warning and activates no layer”. The install looks like it worked and nothing happens.What it actually is: DeepSeek Harness: Everything is a Plugin. If that is what you came for, use it directly from the repository — it is just not something dsh plugin add can activate.
Before you run itinstall scripts
- This package declares
postinstall— package-manager lifecycle scripts that execute on your machine at install time, outside the agent sandbox, before any tool-approval prompt exists. - A plugin runs with your permissions once loaded: it can read your files, use your credentials and reach the network. Tool approvals do not sandbox it.
- Installing from git resolves a moving branch. Pin a commit —
github:deepseek-ai/deepseek-harness#<commit-sha>— so the code you reviewed is the code you install.

From the README
Excerpt as published by the author, plain text, unedited
English | [中文](README.zh.md) DeepSeek Harness (`dsh`) is an open-source agent harness developed by [DeepSeek AI](https://deepseek.com). It uses an architecture where **everything is a plugin**, and is powered by [Cordis](https://github.com/cordiverse/cordis), whose design is described in [_A Programming Paradigm for Spatiotemporal Composability_](https://github.com/cordiverse/paper). DeepSeek Harness is currently in _developer preview_ and is iterating rapidly. **THERE WILL BE COMPATIBILITY-BREAKING CHANGES.** Install `Node.js`, then run:

Dsh Plugin Session Delete

Delete DeepSeek Harness sessions from the UI: header danger button + sidebar session-row menu item (no conversation jump), risk-consent dialog with session name/id, stops running agents first, in-place list refresh without page reload. Works in web and the desktop client.

Dsh Genui
omdsh-dev
GenUI for DeepSeek Harness: interactive UI components rendered inline in assistant replies via the dsh-ui fence — layout, charts, plots, forms, quizzes, mermaid, 3D scenes, and an action event loop back to the model. Ships the fence-teaching host plugin, the browser renderer (client half), and the genui skill.
