How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude or any similar agent and adjust the details to your situation.

Convert this PDF schedule into an .ics file. Then compare your file to the PDF and list any events that don't match.

Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
