Introduction

In the plugin extension scenario of DeepSeek Harness (DSH), certain interface setting capabilities can be added through independent plugins without the need to replace DSH itself. cjz-wr/background-plugin provides background setting capabilities: supporting local or online images/videos, and allowing adjustment of opacity.

What is this

cjz-wr/background-plugin is a DSH Background plugin, with the GitHub repository path cjz-wr/background-plugin and an MIT license.

It is used to add background-related settings to DSH. The documentation clearly states it is not an official built-in feature of DeepSeek Harness, but an independent add-on.

Core Features

According to the documentation, this plugin includes the following capabilities:

  • Background plugin
  • Supports local or online images/videos
  • Allows adjustment of opacity
  • Persisted background image/video preferences
  • General settings row
  • Document presenter

Installation and Activation

You can search for the repository in the DSH Web Plugin (Plugins) settings interface and click to install.

You can also install via CLI:

dsh plugin --profile <name> add github:cjz-wr/background-plugin

Replace <name> with your own profile. Usually, you can use web:

dsh plugin --profile web add github:cjz-wr/background-plugin

The newly installed bundle layer will participate in compose on the next process startup.

Developer Build

The build artifact lib/ of this project is intentionally committed to the repository. Git, npm, and tarball installations will use the repository content directly without needing to execute build scripts; the documentation also explicitly states there is no prepare script.

If you modify src/, you need to rebuild locally and commit the new lib/:

npm run build

Use Cases and Notes

This plugin is suitable for users who need to add background image/video settings, opacity adjustment, or persisted background preferences in DSH.

The documentation is clear: the official DeepSeek Harness does not include this feature; as an independent add-on, it can be cleanly installed into any profile. The only thing to note is that if the target DSH build already has a row with the ID ui-background, installing this plugin will cause a mount error at startup:

duplicate loader entry id: ui-background

In this case, you should install it into a profile that does not contain this built-in row.

Since the plugin runs with the permissions of the current dsh process, you should check the source code, license, and installation method before installing. The current documentation explicitly states the license is MIT.
