NoNameLeGo/dsh-catppuccin-theme

NoNameLeGo/dsh-catppuccin-theme is a custom Catppuccin theme built specifically for DeepSeek Harness (DSH), with a native DSH plugin manifest that lets it integrate seamlessly with DSH’s plugin system. It supports all three DSH interface variants: the web GUI launched via dsh web, the standalone DSH Desktop app, and the terminal-based dsh-TUI. The package includes all four official Catppuccin themes, adds a dedicated quick-switch section to DSH’s appearance settings, and persists theme selections across application restarts. To install the stable release from npm, you run the command dsh plugin --profile web add @nonamelego/dsh-catppuccin then restart your DSH instance.

This theme is targeted at DSH users who prefer the soft, cohesive muted color palette Catppuccin is known for over DSH’s default appearance options. After installation and a quick restart of DSH, you can switch between any of the four themes directly from the settings panel with one click. You can also enable an optional glassmorphism effect for UI elements like the sidebar, top bar, and chat bubbles, and adjust the blur, opacity, and background brightness to match your personal visual preference. All customization options are saved automatically so you don’t have to reapply them every time you open DSH.

The plugin is released under the permissive open-source MIT license, so it is free to use, modify, and distribute for any purpose. It is hosted on the public npm registry, and the official installation method is via DSH’s built-in plugin command line tool, which handles all dependency setup automatically. The plugin includes built-in update checking that runs once on launch and then every 6 hours by default, and you can also trigger a manual check for new versions directly from the DSH settings panel. It also supports custom overrides for individual color tokens and offers two different code block highlight styles for users to choose from.
