Introduction

The DeepSeek Harness Web interface is composed of multiple surfaces by default: page base, cards, panels, sidebars, chat bubbles, and code blocks. If you wish to lay a custom background across the entire Agent interface while keeping these surfaces readable, you need a plugin that only adjusts the visual theme. Below is an introduction to dsh-liquid-glass: once enabled, the entire shell becomes semi-transparent, and transparency can be controlled via a slider while changing the full-page background.

What is it

dsh-liquid-glass is a DeepSeek Harness plugin maintained by Ultronen under the MIT license. It targets the web client and is injected immediately. This plugin does not modify business processes; it only handles three visual-related tasks:

  • Overall transparency
  • A master transparency slider
  • Full-page custom background

Core Features

Full Shell Transparency

The plugin adjusts the surfaces drawn by the shell to be semi-transparent via the official ThemeRuntime token-override layer. Verified to include the page base, cards, panels, sidebars, chat bubbles, and code blocks.

A Master Transparency Slider

There is only one main slider with a range of 3%–95%. The higher the slider value, the more the background shows through.

Full-Page Custom Background

You can upload a local image or paste a URL. Local images are compressed first and then used in the current browser’s localStorage. The background will appear as the full-page background.

Installation and Activation

First, execute the installation command:

dsh plugin --profile web add dsh-liquid-glass

After installation, open Settings → General, and the Liquid Glass line will appear. The default state is ON; restart once after installation.

Typical Usage

  1. Install the plugin and restart once.

  2. Open Settings → General and confirm that Liquid Glass is enabled.

  3. Use the master transparency slider to adjust the background opacity, ranging from 3%–95%.

  4. Upload a local image or paste a URL to serve as the full-page background.

To remove the plugin, execute:

dsh plugin --profile web remove dsh-liquid-glass

After uninstallation, preferences in the current browser’s localStorage are retained, but there will be no further impact.

Applicable Scenarios and Notes

This plugin is suitable for scenarios where you want to use a custom background in the DeepSeek Harness Web interface while keeping the interface semi-transparent. The DSH plugin directory is a community directory and does not constitute an official app store relationship with DeepSeek or High-Flyer.

The plugin runs with the permissions of the current dsh process; it is recommended to check the source code and license before installation.

The peerDependencies are:

react: ^18.2.0
@deepseek-ai/cordis: ^4.0.1

Local image uploads are compressed first to be stored in localStorage. Preferences are saved in the current browser and are retained harmlessly after uninstallation.

Conclusion

The value of dsh-liquid-glass is focused: it uses a single switch to change the transparency of the entire DeepSeek Harness shell, and uses a slider and a full-page background to complete the visual adjustment. The GitHub URL is:
