DeepSeek Harness supports extending Web UI features through plugins. The default appearance is relatively generic and may not meet personalized needs. The plugin dsh-fgo-chaldea provides an FGO-style visual skin that overrides color schemes via the Token API and programmatically generates backgrounds and decorations, allowing developers to customize the interface style.

Plugin Positioning

An FGO Chaldea-style DeepSeek Harness Web UI skin plugin. Author: Nuomi9. Category: Fun reskinning. The code and background images are released under the MIT License.

Core Features

  • 5-token themes: Includes “Chaldea · Night/Morning”, “Artoria · Blue Gold”, “Morgan · Black Purple”, and “Mash · White Purple”.
  • Programmatically generated backgrounds: Generates original star charts and magic circuits programmatically based on SVG. Each theme has an independent color scheme and does not depend on any image files before packaging.
  • Visual decorations: Gold engraved-line borders, four-corner decorations, and breathing animations (compatible with prefers-reduced-motion).
  • Settings integration: Registers an “FGO Chaldea” selection card in “Settings → General Settings”.
  • Local memory: The skin selection is saved in localStorage and automatically restored after refreshing the page.
  • Technical implementation: Based on the ctx.theme token API; does not include any official FGO art assets.

Installation and Enablement

Prerequisite: DeepSeek Harness development preview (0.1.0-rc.5/rc.6).

Installation command:

dsh plugin --profile web add github:your-name/dsh-fgo-chaldea

Enablement steps:

  1. Restart dsh web.
  2. Open http://127.0.0.1:3080.
  3. Go to Settings → General Settings → FGO Chaldea.

Usage Notes

After switching skins in the settings interface, the system automatically applies the color scheme and background. Refreshing the page reads the selection state from localStorage and restores it.
