A rule is three things: the event it listens for, the conditions that narrow it, and what it does. Rules are written in vibescript, a small language with the dispatch operations built in. Ask Assistant to draft one, or write it yourself.
The host hands scripts the same operations a dispatcher has. Nothing more.
Assistant reads your current board before it answers, drafts the rule in vibescript, and compiles it before offering to add it. If it does not parse, you never see it. Edit what it produces, or start from a blank rule.
We will write it with you on the demo call and leave it in Simulate so you can check it for a week.
