dsh-neo-skin: Overlaying Neo-brutalism Skin on DeepSeek Harness Web UI

Preface

The DSH Web UI already supports three appearance modes: light, dark, and system. If you want a more pronounced border, hard-shadow, and high-contrast style without replacing the built-in theme, you can install dsh-neo-skin. It is a Web UI client skin plugin within the DSH plugin ecosystem that overlays neo-brutalism tokens on the built-in light/dark color schemes via the official theme service.

What Is This

dsh-neo-skin is a zero-dependency client-side skin plugin, licensed under MIT, with its repository at 0nt-one/dsh-neo-skin.

It does not replace DSH’s built-in themes; instead, it overlays --dsw-alias-* semantic token overrides. This way, the light, dark, and system modes still work, and the skin applies to both the light and dark color schemes simultaneously.

Core Features

  • Includes two built-in schemes, Blue Command and Aged Newspaper, which can be switched in real time under Settings → General → Neo Skin.
  • The plugin toggle is persisted in localStorage, enabled by default; disabling it returns to the official color scheme.
  • Scheme selection is persisted in dsh-neo-skin.scheme, and switching applies the full set of color and structural overrides.
  • The structural layer provides hard-offset shadows, right-angled key panels, 2px borders, and button press displacement feedback.
  • Adapts theming for dsh-voice-input popups, buttons, and status colors.
  • Compatible with light, dark, and system themes.

Installation and Activation

Below are the reproducible offline/development installation steps from the documentation. First, prepare the local repository directory <path\to\dsh-neo-skin>, then build the bundle.

npm run build

After the build, install the plugin into the Web profile.

dsh plugin --profile web add <path\to\dsh-neo-skin>

Next, register the plugin line in .dsh/profiles/web/cordis.patch.yml.

- insert:
    - id: dsh-neo-skin
      name: 'dsh-neo-skin'

Finally, restart the Web profile.

dsh --profile web

For the initial installation, the host needs to be restarted to mount the plugin; afterwards, if you only rebuild, a hard refresh in the browser will load the new bundle.

Typical Usage

After installation and restart, enable or disable the plugin under Settings → General → Neo Skin, and select either Blue Command / Aged Newspaper on the same line.

To add or adjust schemes, place three files under src/schemes/:

src/schemes/<name>.tokens.json
src/schemes/<name>.meta.json
src/schemes/<name>.css

Then rebuild.

npm run build

After modifying the build, hard refresh in the browser is sufficient—no host restart is needed.

Applicable Scenarios and Notes

This is suitable for users who want stronger borders, shadows, and a high-contrast style in the DSH Web UI, especially those who need to maintain the same skin under light / dark / system.

Important notes:

  • The plugin runs with the current dsh process permissions; you should review the source code and license before installation.
  • The structural layer targets components using human-readable suffix selectors like [class* "_xxx"]; you may need to fine-tune these if DSH undergoes major refactoring of class names.
  • The toggle and scheme use localStorage for persistence. According to the documentation, the host apiproxy only exposes settings.describe for namespaces on the WEB_SETTINGS_NAMESPACES whitelist; third-party plugin namespaces will receive settings-not-exposed.
  • The current documentation does not provide online/directory installation commands, only offline/development installation commands.
