lunageller/vibe-coding-prd

This repository is a skill for coding assistants like Claude Code and Codex that turns rough product ideas into a clean product requirements document, or PRD, that a coding agent can act on directly. You trigger it by typing a phrase asking it to write a PRD for vibe coding, and it accepts several kinds of starting material: a clear idea, a long original PRD written for business stakeholders, notes from looking at a competitor's product, or just scattered thoughts that are not yet organized. The skill follows a defined workflow. First it figures out what kind of input it has received. If the input is unclear, it asks multiple choice questions to help the user pin down what they actually want, rather than guessing. Once the need is defined, it designs the feature modules, decides what belongs in the minimum viable product versus a later version or not at all, suggests a technology stack in plain terms, sketches a basic interface prototype, works out detailed feature designs, and writes acceptance criteria that describe an observable, testable result rather than a vague goal like a good experience. The final output is a short markdown PRD aimed at a coding agent rather than an investor or a business audience. It includes sections for the type of input received, the core requirement definition, MVP scope, suggested tech stack, an interface prototype outline, detailed feature design, acceptance criteria, and implementation notes telling the coding agent what to build first and what can be mocked. To install it, you clone the repository into the Codex skills folder. It is intended for people who want to quickly prototype a product with a coding agent, especially those who only have an idea, have an overly long PRD, are trying to build on what a competitor already made, or do not know enough about technology to choose an implementation approach themselves.
