Score startup idea through S.E.E.D. niche check + STREAM 6-layer analysis + Devil's Advocate inversion, auto-pick stack, and generate PRD with acceptance criteria. Use when user says "validate idea", "score this idea", "should I build this", "go or kill", "generate PRD", or "evaluate opportunity". Do NOT use for deep research (use /research first) or decision-only framework (use /stream).

通过S.E.E.D.细分市场检查、STREAM六层分析和魔鬼代言人逆向思维对创业想法进行评分，自动选择技术栈并生成包含验收标准的PRD。当用户输入“验证想法”“评分此想法”“我该不该做”“做或放弃”“生成PRD”或“评估机会”时使用。不用于深度研究（请先使用/research）或仅用于决策框架（请使用/stream）。
