Developers, I recommend you do this asap: ask Codex to run your app and try to figure out how to do a task, without seeding it with any information.
It's like putting a new user in front of the screen, and watching how they operate it. It will very rapidly expose any problems you have in messaging or user education, and it's a little eye-opening if you've never (or not recently) run user tests.
Turns out, I have work to do 😅
