Configure personas, enter an assumption, and fire them all at once.
This feedback is AI-generated. While I have been careful with the prompts guiding the various personas, the feedback could be completely off or just odd. Take it as one input, discuss it thoroughly in your team, and prepare to argue the direction you then choose. If you tell me later that my 'Assumption Stress Tester' told you to do something and it turned out not to work, I'll simply repeat 'I told you so'.
