What is it?

Product Engineering is a collection of agent skills in SKILL.md format for building and running a product with coding agents such as Claude Code, Codex, Cursor and Gemini CLI. It covers the whole path: deciding what to build through research and a prototype, building and reviewing the code with separate agent sessions, releasing through a gated process, and running production with real users, payments, email and monitoring.

The skills are grouped into packs: product for deciding what to build, ai-shipping for reviewing and releasing AI-built apps, agent-teams for coordinating several agents, agent-harness for reliable agent setup, app-stack for a SaaS on Next.js, Supabase, Clerk and Netlify, and work-humanizer for editing AI-sounding text. The packs install through the Claude Code plugin marketplace, Codex plugins, or the npx skills tool.

The project is aimed at product managers, founders and designers who ship with coding agents, and at engineers who also own the product decisions and production operations. It is a Python repository under the MIT License, maintained alongside the pm-skills collection.

Key features

  • 01Covers the full path from idea research to a prototype, build, release and production operations.
  • 02Organizes 43 skills into six installable packs.
  • 03Installs in Claude Code, Codex, and other agents that read SKILL.md folders.
  • 04Runs code review with a fresh reviewer session that did not write the change.
  • 05Includes a release gate, environment separation, and production checks for a SaaS on Next.js and Supabase.

Use cases

  • A product manager shipping a small SaaS with Claude Code or Codex without writing code by hand.
  • A founder deciding what to build and validating it with a prototype before building the app.
  • A team running several coding agents where one coordinates, one builds and another reviews.
  • An engineer adding a release gate, legal pages, and email to an existing web app before launch.

Quick start

  1. 1

    Add the marketplace in Claude Code

    claude plugin marketplace add phuryn/product-engineering
  2. 2

    Install the product pack

    claude plugin install product@product-engineering
  3. 3

    Type /product:start-here in Claude Code and say what you have

Things to know

  • The npx installer for other agents needs Node.js 22.20 or later.
  • Some production skills assume third-party services such as Supabase and Clerk.
