Give your Grok Bot a rival inbox that logs competitor prices to a sheet
Have the bot claim its own email address, join competitors' mailing lists and connect Google Sheets. After a week it sums up their offers and launches, logs prices to a sheet, saves that as a "rival watch" skill and runs it every Monday at 9am, flagging any price that moved.
