Idea Autopsy

Stress-test a business idea — especially one an AI suggested — before anyone builds it. Use when the user says "autopsy this", "is this a business or bullshit", "test this idea", or pastes a startup/side-hustle idea and wants to know if it's real. Returns one of four verdicts: BUSINESS, BUSINESS WRONG OWNER (real idea, wrong constraints — says which), BULLETIN (it's really just content or information), or BULLSHIT, plus the smallest test that would prove it wrong. Built from a four-hour session in which an LLM pitched twelve businesses and eleven died.
