wtf is vibe-coding-prd?

vibe-coding-prd is a Claude Code skill that turns a vague idea, a traditional business-style product requirements document, or a competitor analysis into a short, structured document meant to be handed directly to a coding AI agent like Claude Code or Codex. The README and skill are written in Chinese. The problem it addresses is that writing code usually is not the hard part. Figuring out exactly what to build is. A traditional product requirements document is written for humans and includes things like business value, market analysis, and success metrics, most of which a coding agent has no use for. This skill strips all of that away and keeps only the details a coding agent actually needs to start building, while forcing every acceptance criterion to be something concretely testable, such as clicking a button and seeing a specific result, rather than vague phrases like good user experience or excellent performance. When used, the skill first figures out what kind of input it has been given, whether that is a clear request, a traditional PRD, or a competitor analysis, and asks clarifying questions whenever a judgment call needs to be made rather than guessing on the user's behalf. It then walks step by step through defining the requirement, listing features with priority levels, recommending a beginner-friendly tech stack, sketching a basic prototype layout, detailing each feature module, and writing verifiable acceptance criteria. The result is saved as a single Markdown file ready to be handed to a coding agent. Installing it means copying the SKILL.md file into Claude Code's skills directory, either by downloading it directly or cloning the repository. This project is aimed at developers using Claude Code or similar AI coding agents who want a lightweight way to turn rough ideas into an actionable, agent-ready specification document.
