A Hermes Desktop theme that follows your wallpaper. Reads Pywal's ~/.cache/wal/colors.json by default, or any palette JSON you point it at (settings page or ~/.config/hermes-wallpaper-theme/config.json), derives a palette with checked contrast floors and repaints live when the file changes. Optional glass mode paints a translucent background for native window materials or compositor blur.

## Good to know before installing

The desktop half uses only @hermes/plugin-sdk; the palette file is read by the package's own backend route (dashboard/plugin_api.py, GET /api/plugins/wallpaper-theme/palette, mounted once the plugin is in plugins.enabled), polled every 3 seconds with a change stamp. That route reads only JSON files inside the user's home directory (or XDG_*_HOME) under 256 KiB and returns colour fields only, never raw file text. No network calls, no shell commands, no credentials, no telemetry.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install wallpaper-theme
```

2. Said no? Turn it on later:

```bash
hermes plugins enable wallpaper-theme
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
