- 0.29.1Questions the way agents ask themQuestionSet asks an agent's clarifying questions the way agent tools do: a visible Question 2 of 3, a suggested option marked Recommended and listed first, questions that take several answers, You decide and Skip, Use the defaults to end the questions, Back, number keys to pick an option, and a last look at every answer with a Change link before the final button. Every addition is optional, so existing code is unchanged.
