I can't run a few bash calls or a Python+UV script in Mobile Safari on my phone. That's very much a goal of most of these as well.
I actually have a separate collection of vibe-coded UV+Python scripts on that site here: https://tools.simonwillison.net/python/
We failed at creating automation tools for the users (even if Apple tried that with AppleScript or Automator), but vibe coding throwaway scripts is not the answer.
