Expose local services and files to the internet through a public HTTPS URL. Designed for AI agents — when you need to let a user preview files remotely, share a dev server, demo an app, or give temporary access to localhost. Use this whenever the user says "share this", "let me see it on my phone", "send me the link", or needs to access something running locally from another device/network.
