Product Review Panelv1.0.1

Convene a multi-expert panel to review a Product Requirements Document (PRD) and deliver a binding verdict (GO / NO-GO / CONDITIONAL GO) with dissenting opinions preserved as first-class output. Use when a Product Manager wants critical review of a written PRD, when deciding whether to build a specific feature, when stress-testing a proposal across product / UX / business-model dimensions, or for a structured "second opinion" before committing engineering resources. The panel adapts to the user's conversation language (Chinese → Cagan + 俞军 + 大厂 P9 产品总监 + situational like 张小龙; English/other → Cagan + Christensen + Senior PM Director + situational like Norman, Jobs, Hoffman, Torres). Every review ends with a verdict from "The Closer" (魔鬼裁判) plus observable failure signals to monitor. Do NOT use for pre-PRD idea brainstorming, purely technical architecture reviews, non-product strategy questions, or user research synthesis — use other skills for those.
