I’ve never used an agent for the cliches of ordering food, grocery shopping, or booking travel. But I repeatedly use Computer Use in Codex to add things to my family calendar in Apple Calendar. Like, I gave it my son’s little league schedule for the next four months, and it added all the dates and diamonds. Then, screenshots of my daughter’s upcoming swim meet schedule, and it added all the times, events, and pools. Not revolutionary, but useful, and easily saved me a few hours of data entry.
