Expose a port
Give something running on your computer a public URL.
Fill it in
Where the thing is running.
The local port to expose.
Start narrow. You can widen it later.
Your prompt
Expose port 1 at a public URL. Computer: . Reachable by: workspace. Check something is actually listening on 1 first. A tunnel to a closed port produces a URL that returns nothing, which is the confusing failure. Then `computer port-open`, and `computer port-make-public` only if the user chose public. Report the URL. Say plainly who can reach it. A URL the user thinks is private and is not is the one mistake here that matters.
Continue and add your fileOpens with everything above already filled in.
