Add a new .agents/skills/halo-theme-dev skill providing Halo theme development resources: two theme templates (theme-vite and theme-minimal) with theme.yaml/settings, Vite config, package.json, CSS and JS assets, and a full set of Thymeleaf template files/partials. Include comprehensive reference docs (structure & config, finder APIs, global variables, annotations, static resources, packaging, official plugins, thymeleaf tips) and an agents/openai.yaml interface. Also update project files: modify package.json, update tsconfig.json, add skills-lock.json, rename vite-env.d.ts and remove obsolete src/main.ts and src/styles/main.css while populating src/ with the new template files.

Official Plugin Integration
Halo's official plugins can extend the frontend UI. Themes should adapt to these plugins rather than re-implementing the same functionality.
Checking Plugin Availability
Use pluginFinder.available(pluginName) to conditionally render plugin-dependent UI. This prevents broken UI when the plugin is not installed.
<button th:if="${pluginFinder.available('PluginSearchWidget')}"
onclick="javascript:SearchWidget.open()">
Search
</button>
Always guard plugin-dependent elements with th:if="${pluginFinder.available('...')}".
Search Widget (PluginSearchWidget)
The official search plugin provides a ready-made search UI. Themes do not need to build their own search — just add a trigger button:
<button th:if="${pluginFinder.available('PluginSearchWidget')}"
onclick="javascript:SearchWidget.open()">
Search
</button>
Dark Mode Adaptation
Official plugins that provide UI components (search widget, comment component, etc.) support a shared color scheme system. Themes that implement dark mode should apply the appropriate class or data-color-scheme attribute to <html> or <body> so plugin UI matches the theme's color scheme automatically.
Method 1: CSS class on <html> or <body>
| Class | Effect |
|---|---|
color-scheme-auto |
Follows system dark/light preference |
color-scheme-dark or dark |
Force dark mode |
color-scheme-light or light |
Force light mode |
<html class="color-scheme-dark">
<!-- or -->
<html class="dark">
Method 2: data-color-scheme attribute on <html> or <body>
| Value | Effect |
|---|---|
auto |
Follows system preference |
dark |
Force dark mode |
light |
Force light mode |
<html data-color-scheme="auto">
Both methods achieve the same result. Dark mode switching is typically handled by frontend JavaScript (toggling the class/attribute at runtime). This applies to all official plugins that render UI (search widget, comment component, etc.).
