ask-questions

Surface the open questions in the current work and put them to the user as structured choices. Use whenever the user says "ask questions", "ask me questions", "what do you need to know", "what's still open", "any open questions?", "quiz me on this", "check with me before you build", or otherwise invites being asked rather than guessed at — mid-design, before implementing, or when the conversation has accumulated unresolved decisions. Also use when the user wants the open questions on the current branch or plan reviewed. Never invents answers or options.
