Automatons answer in your home folder, and can build
Talking to an automaton while your home folder is open now works, and a new switch lets an automaton change files in a project.
An automaton usually works in a private copy of your project, so nothing it does touches your files until you apply it. Your home folder also holds Bandicot's own data, which can't be copied, so the engine refused the message.
Now it answers in the folder itself and only reads there. To let an automaton build what you approve, turn on Let it change files under More on its Job card. In a project it then works on a copy you review before anything is applied.
