Tauri Shell UI

Bundled commands use $PLUGIN_ROOT ($env:PLUGIN_ROOT in PowerShell; same path suffix) for the plugin root. Set it once: use the host's plugin-root variable when defined (Claude Code: PLUGIN_ROOT="$CLAUDE_PLUGIN_ROOT"), otherwise the absolute path of this plugin's root directory.

Use this skill for native app-shell behavior around a web frontend: windows, menus, tray, titlebars, resources, icons, sidecars, opener/shell APIs, and deep links.

First Pass

Run the probe, then inspect window labels and app config:

python3 "$PLUGIN_ROOT/scripts/tauri_project_probe.py" .

Relevant files usually include src-tauri/tauri.conf.*, src-tauri/capabilities/*, src-tauri/src/lib.rs, frontend window/menu/tray code, and bundled resource paths.

Windows And Webviews

• Capabilities target window/webview labels, not titles. Keep labels stable.
• Custom titlebars require both frontend UI behavior and native window config.
• Avoid layout shifts in custom chrome: fixed toolbar heights, clear drag

regions, and accessible controls.

• Account for platform differences in close/minimize/fullscreen/menu behavior.

Resources, Icons, Tray, Menu

• Store bundled resources in the configured Tauri resource location and access

them through Tauri path/resource APIs.

• Keep icon generation and references in sync with bundle.icon.
• Menus and tray icons differ across macOS, Windows, and Linux; implement the

platform-specific behavior users expect.

• Do not expose menu/tray actions that call privileged commands without matching

capabilities and validation.

Sidecars And Shell

• Prefer native Rust commands unless a sidecar materially reduces risk or

complexity.

• Sidecars require bundled binaries, lifecycle handling, platform-specific

paths, and explicit shell permissions.

• Treat sidecars, opener, and shell APIs as security-sensitive. Scope commands

and arguments tightly.

Verification

For visual shell changes, run the frontend path and the Tauri shell path when possible. For sidecars/resources, verify packaged build behavior, not only dev server behavior.
