The goal, of course, is to do as much nothing as possible.

First, you tell people that you are unlocking the front door of your home and not feeding your dog that day, and it’s up to all of them to come over and feed the dog. Then you make a spreadsheet. The spreadsheet is mostly blank, but it has some line items like “clean my house” and “a steak for the dog”, as well as a few dozen lines for food things that people should bring. You used to include beverage line items, but those turned into a form of low-effort posting, and one shows up correctly to potluck.
