The script collects hostname, username, home directory, local IPv4, INIT_CWD, and the public egress IP (queried from api.ipify.org, icanhazip.com, and ifconfig.me), and reads the consuming project's package.json (INIT_CWD/package.json) to extract name, author, repository, and homepage — identifying which internal package name resolved to this public package.
