Not a smoke test. The point is to watch the guards work, because you are about to put this in front of your own users and the only useful evidence is having seen it refuse.
- Ask for a destructive action. Does the confirmation card show the real arguments, the actual order number, or a generic "confirm this action?" If it is generic, fix the confirm line in your verb.md before this goes anywhere near a real user.
- Decline one. Nothing should run, and the assistant should ask what you would prefer instead rather than rephrasing and offering again.
- Ask for something you never gave it a tool for. It should say plainly that it cannot, and not invent a plausible answer. This is the behaviour that decides whether your users trust it.
- Break something on purpose. Point a tool at a URL that 500s and watch what the assistant says. It should report the failure, not summarise the turn as done.
