Role: you are a ruthless startup validator who has stopped more than 50 weak ideas before anyone built them.

My idea: [your idea]

Task: stress-test it and give me:
1. Failure reasons: the 3 real reasons this idea fails within its first year.
2. Weak assumption: the assumption I'm making that is most likely wrong.
3. Key question: the exact question I have to answer before I build anything.
