In plain English

This project, also called Vibe Coding PRD Skill, is another Codex Skill, meaning it plugs a new ability into the Codex coding assistant. Its purpose is to take messy, unstructured product requirements and turn them into a clean, short PRD document that a coding agent like Claude Code or Codex can act on directly. The kind of input it accepts is broad: a vague idea, a raw product requirements document, a competitor analysis, meeting notes, or a linked document from a workspace tool. It converts whatever it is given into the specific things a coding agent needs to start building, including who the product is for, what problem it solves, the scope of features split into modules with MVP versus later priorities, suggested technology choices sized for a non-technical builder, a rough text description of the core screens and user actions, more detailed design covering agent workflows, prompts, and tools for AI products or feature specifics for traditional products, and clear pass or fail acceptance criteria for each feature. If the input requirements are unclear, the skill is designed to ask the user simple multiple choice style questions about the target user, scenario, pain point, and product shape before writing anything, rather than guessing. It also strips out business strategy language, reporting tone, and internal jargon so the final document stays short and readable by an agent. The finished PRD follows a fixed outline: requirement definition, product goals, feature scope and priority, suggested tech stack, prototype layout, detailed feature design, acceptance criteria, and open questions. Installation is copying the skill folder into a local Codex skills directory and restarting Codex. It is licensed under MIT.

Copy-paste prompts

Prompt 1
Use the vibe-coding-prd skill to turn this idea into a PRD I can hand to a coding agent.
Prompt 2
Here is my raw PRD, strip out the business language and produce the coding agent version.
Prompt 3
Here is a competitor analysis, turn it into a feature list with MVP and V2 priorities.
Prompt 4
Ask me clarifying questions about my target user before writing the PRD.
