prd-writing-skill

Structured product requirement writing workflow for turning ideas, Feishu docs, PRD drafts, HTML prototypes, app/mini-program/PC demos, or screenshots into a complete PRD. Use when the user asks to write, update, rewrite, review-then-write, or directly publish a PRD/需求文档/产品方案, especially when the work should first inventory source materials, clarify requirements with brainstorming or Superpowers, create a requirement brief, design page/state inventory, build or inspect a prototype demo, then write a PRD with background, roles, permissions, business flowchart, requirement description, session/concurrency handling, PV/UV analytics events, acceptance checklist, and Feishu-ready screenshots.
