Introduction

DeepSeek Harness (DSH) adopts a plugin-based architecture, allowing users to customize the workbench through extensions. Although the default interface is feature-complete, there is still room for improvement in visual details, brand consistency, and readability for long Chinese conversations. dsh-sakura-theme is a community-maintained theme plugin designed to provide a complete visual redesign for DSH Web. It includes two full theme sets—light “Clear Cherry Blossom” and dark “Night Cherry Blossom”—without changing the existing functional behavior.

Core Features

This plugin is more than a wallpaper replacement. It rewrites the visual tokens from the ground up and implements a systematic design refresh.

  • Dual-theme support: Provides two complete themes: Clear Cherry Blossom (light) and Night Cherry Blossom (dark).
  • Automatic following: Automatically follows the Light / Dark / System preference in Harness.
  • Comprehensive redesign: Redefines the brand, color palette, typography, icons, cards, and interactive states.
  • Reading optimization: Builds in the LXGW WenKai Screen Reading GB font, making body text warm and clear while keeping code areas in monospace fonts.
  • Dynamic effects: Vector petal layers slowly drift from the upper right to the lower left, and respect the prefers-reduced-motion specification.

Installation and Activation

The installation process is completed through the DSH plugin command line.

  1. Run the installation command in a terminal:
    dsh plugin --profile web add dsh-sakura-theme
  1. After installation, you must fully restart the dsh web process. Simply refreshing the page will not apply the theme, because brand replacement involves disabling the ui-brand-official placeholder, which requires a process-level refresh.
  2. After restarting, select Light, Dark, or System in the appearance settings of DSH Web. The plugin will automatically apply the corresponding Clear Cherry Blossom or Night Cherry Blossom theme.

Compatibility and Dependencies

Before using the plugin, verify your environment version to ensure that the plugin can load tokens and styles correctly:

  • DeepSeek Harness Web 0.1.1-rc.2 series or later.
  • Node.js 20 or a newer version.

Notes

  • Unofficial plugin: This project is maintained by the community and is not affiliated with the DeepSeek official team.
  • License: The code is released under the MIT License, and the built-in font is released under the SIL Open Font License 1.1.
  • Brand replacement mechanism: To achieve a unified visual language, the plugin disables the built-in ui-brand-official occupant. If you need to switch back to the official brand, you must manually restore that placeholder in the configuration.
  • Update requirement: After updating the plugin, a full restart is required. Simpage refreshing the page is not sufficient to load the new brand configuration.

Summary

For developers who want a more unified and visually pleasing Chinese reading and interaction experience in DeepSeek Harness, dsh-sakura-theme provides a reversible solution. The code is hosted on GitHub, and the repository page provides more details.
