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 40 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 app from idea to paying customers.

Give this to your agent inside your project

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. Every skill does the work with you and hands you a real file the next one reads.

01 · DEFINE8 SKILLS

Your product strategist

Sharpens the idea into an offer people will pay for, a target customer, and a pricing strategy, then validates it before you build.

02 · DESIGN9 SKILLS

Your product designer

Gives your product a brand identity, design system, writes your landing page, app store listing and designs your onboarding flow to convert users to customers.

03 · DEVELOP15 SKILLS

Your engineering lead

Turns the spec into a roadmap and builds it with a review, test, and fix loop, then audits security and deploys it to real customers.

04 · DISTRIBUTE4 SKILLS

Your growth lead

Picks your channels, runs ranked growth experiments with a pass bar on each, and logs what actually works so you know where to scale.

THE SKILLS

Every skill, and what it does

You don't need to learn all 40. Start with ship-in-7 and it runs the right ones for you. Open a phase to see what's in it.
