Electron Extract skill: what it does and how to install it

What it does. Finds an installed Electron app or accepts an app.asar path, then extracts its resources with a Bun or npx command. It restores embedded sourcesContent from JavaScript source maps where available, otherwise formats bundled JavaScript with Prettier, skips node_modules, and reports output paths and counts.

When to use it. Use it to inspect how an installed Electron desktop app is built or read its bundled code. On Linux or other unsupported platforms, provide the app.asar path explicitly; it does not restore sources when maps lack embedded content.
