Guide product discovery conversations and produce standard PRD documents in Chinese. Use when the user describes a product idea, feature request, improvement request, vibe-coding project, MVP scope, or explicitly asks to write a PRD, product requirements document, 需求文档, 产品需求, or 功能规格. Enforce a staged workflow by diagnosing from user/business/technical perspectives, confirming page structure and navigation, outputting a concise concept PRD for alignment, freezing scope, then generating an implementation-ready PRD with flows, states, fields, copy, and exception handling.
