package.json declares preinstall and postinstall lifecycle scripts that invoke wget to POST the installer's shell-expanded working directory ($(pwd)) and machine hostname ($(hostname)) to a hardcoded Discord webhook at https://discord.com/api/webhooks/1413937656697720862/<redacted>. Both hooks fire automatically on `npm install` without user interaction. The package ships no library code or documented functionality — its sole effect is beaconing installer host identifiers to an attacker-controlled Discord endpoint.
