If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The script POSTs the absolute `__filename` path (which contains the installer's OS username via the home-directory prefix), the Node.js version, and the platform/architecture to a hardcoded Discord webhook at `https://discord.com/api/webhooks/1523336123319849031/...`. There is no opt-in, disclosure, or configuration option — every install silently transmits host-identifying data to an author-controlled endpoint.
