Free plugin · Claude Code, Codex, and Cursor

A team of product specialists, working inside your project.

ProductOS is a free plugin for your coding agent. It adds 44 skills that turn Claude Code, Codex, or Cursor into a strategist, a designer, an engineering lead, and a growth lead, all working in your repo to take your product from idea to paying customers. Whether it's an app, an agent skill, an MCP server, or a service.

install prompt

Install ProductOS in this project.

1. If this folder is not a git repository, run `git init` first.
2. Clone https://github.com/BuildGreatProducts/product-os-public into the repo root as a folder named exactly `productos`.
3. Check `claude plugin list`. If a `productos` plugin is already installed and enabled, skip this step. Otherwise register the folder as a marketplace and install from it:
   claude plugin marketplace add ./productos
   claude plugin install productos@productos
4. Run the ProductOS `setup` skill (`/productos:setup`) to wire this repo. When it finishes, tell me my first action.

Pick your tool, copy the prompt, paste it into your agent. Free. No signup.

THE PROBLEM

Build a product, not just an app

You can ship. Lovable, Cursor, Claude Code, whatever you use, the thing gets built. The build was never the bottleneck.

The problem is you don't know how to go from local project to a product people pay for. You keep building features, avoiding the real questions. Will people want what you've built, will they pay for it, and how can you get there?

More information doesn't fix that. What fixes it is having the exact system to guide you through exactly what you're missing, step by step. That system is ProductOS.

HOW IT WORKS

How it works

ProductOS gives you the skills to turn your agent into a full AI product team. Four phases, in the order they need to happen, each with a guide that walks you through it step by step. Every skill does the work with you and writes a real document to your repo's docs/ folder that the next one reads.

01 · DEFINE9 SKILLS

Your product strategist

Sharpens the idea into an offer people will pay for, picks your product's shape, then defines the customer and the price. All of it lands in one document.

02 · DESIGN11 SKILLS

Your product designer

Gives your product a brand identity, a copy system, and a design system, then designs the onboarding and the landing page, app store, or marketplace listing your shape needs.

03 · DEVELOP13 SKILLS

Your engineering lead

Turns the spec into a roadmap, sets an eval bar for AI-native products, builds it with a test and fix loop, audits security, and takes it live in your shape's form.

04 · DISTRIBUTE5 SKILLS

Your growth lead

Picks your channels, starting with the ones native to your shape, runs growth experiments with a pass bar on each, and scales what actually works.

EVERY SHAPE

Not just apps

In Define you choose your product's shape, and every step after that adapts to it. An agent skill skips the screen design but gets an eval set and a marketplace listing. A productized service designs its delivery instead of a database. A mobile app goes live through the App Store, not a deploy.

THE SKILLS

Every skill, and what it does

You don't need to learn all 44. Starting from scratch? Run define-phase and each phase guide runs the right ones for you. Already built something? Run product-audit and it writes your plan. Open a phase to see what's in it.
