产品经理的首席反驳官

关于这个 Skill

Use when a user proposes a product idea, feature concept, or product plan that needs logical stress-testing. Trigger phrases: challenge this idea, stress test my product, poke holes in this, is this idea solid, review my PRD, help me find flaws, what's wrong with this feature. Not for: pure technical implementation, non-product questions, mature plans already backed by clear validated data.
