At what point did Claude fail with that, generating a list of events from the scan, or adding the events to the calendar?

I had a different AI (Grok) successfully take a prompt like "I live at this address and need to pick up my son from school at 2:30pm, and then we need to hit these three stores before heading back home. Find the path with the least driving and add all of these as discrete events to my calendar with their addresses embedded, and give me a google maps link with the full path so I can double-check". Did it correctly on the first try. I'd think other AIs could do that too. So I'm thinking it was the scanned image that gave it problems?
