dsh-theme-gallery: A JSON Skin Theme Gallery for DeepSeek Harness

What Does It Do?

Theme Gallery is a DSH plugin for DeepSeek Harness that turns the harness appearance into a gallery of clickable skin cards. It solves the duplication problem of "one plugin per skin": install the plugin once, and every skin ships as plain JSON data, so adding a skin needs no code change, no restart, and no reinstall. Two skins are bundled, each defined by 67 tokens that cover the full screen.

Core Features

• Skins as data: each skin is a JSON file holding only colors and visual overrides, with no runtime logic, so new skins are added as data files.
• Sidebar panel entry: a panel icon opens a full-page card view in the main area, where clicking a card switches the theme and the selection is saved to settings.
• Full-screen coverage with sidebar scenery: skin tokens cover the whole screen and can render an ambient decoration layer for the sidebar.
• Two bundled skins: Shan Qing Ting Cai (mountain green with dragonfly pink) and Meng Hai You Yu (indigo with amber gold), plus a dark theme.
• One switch to disable decoration: a profile config flag turns off the ambient layer and skin restore layer without uninstalling the plugin.

How to Use This Plugin?

After enabling it in DSH, click the "theme skins" icon among the sidebar panel icons; the main area lists every available theme, and clicking a card switches to it while remembering your choice. The entry deliberately does not live under Settings → General → Appearance, because that official row renders only the hard-coded light, dark, and system constants and never reads the theme registry, so this plugin ships its own entry. To add your own skin, drop a JSON file into the theme data directory and regenerate the embedded data, or use the companion skin-authoring skill to have an AI generate one; to share it with everyone, open a pull request. To temporarily silence the decoration, turn the ambient flag off in the profile patch config.

How to Troubleshoot This Plugin?

When the interface refuses to start, the most common cause is writing a skin id into the theme preference: the preference only accepts light, dark, or system, and a skin id makes snapshot building fail and blocks startup, so restore the built-in value as the official docs describe. The desktop profile is owned exclusively by the Electron app, so command-line installation is rejected; in that case adjust the manifest through the official profile mechanism, reinstall dependencies, and restart. If an uninstalled plugin keeps coming back, it is because the bundle list is rebuilt from dependencies, so use the plugin-side config switch to disable it. Back up a clean profile directory first and swap it back if anything breaks.
