In my opinion if the player doesn't tell me their Intent, what they are trying to achieve, how can I assess difficulty? Assess danger? Imagine consequences? I also want the tools for the task they set themselves upon. For the barbarian weapons used, positioning etc. For the talker their arguments. Acting out is not necessary.

Or just use an apocalyptic principle: "to do it, do it". If the character doesn't do anything that triggers a move no move is triggered.
