What You Asked Claude to Do

I uploaded a file to an agent, and my on-computer claude code switched to API billing. It cost me money. Very irritating. All i did was upload a file. I looked at my billing today and saw that every question I asked went to the API billing instead of my Pro account. Nothing indicated that. I would recommend making that much more clear.
