vibe-coding-prd

This skill should be used when the user asks to "帮我写一个用来vibe coding的PRD", "写一份给AI写代码用的PRD", "把这个需求/原始PRD/竞品分析整理成可以直接喂给Claude Code或Codex的PRD", or otherwise wants raw requirements, an engineering-facing PRD, or a competitor analysis turned into a concise, structured PRD document meant to be handed directly to a coding agent (Claude Code / Codex) for implementation. Trigger even when the user's input is just a vague product idea and needs to be clarified first.
