What it does

Product Engineering is a collection of six plugin packs and 44 skills for people who build products with coding agents. The `product` pack takes an idea to a proposal with a prototype, while `ai-shipping` prepares an app for release: review, tests, static security and performance audits, a release gate. The `agent-teams` and `agent-harness` packs cover delegation to other agents, an `AGENTS.md` or `CLAUDE.md` file, guardrail hooks and a handover note between sessions. `app-stack` handles a SaaS on Next.js, Supabase, Clerk and Netlify, and `work-humanizer` edits text that sounds machine-written. Start with `/product:start-here`.

Who it is for. Product managers, founders and designers shipping with coding agents while making the decisions themselves. Also engineers responsible for launching to real users and payments.

Good fit when

  • An idea exists, but it is unclear what to build first.
  • An agent built the app, and a fresh reviewer reads it before every push.
  • A project gets its first `AGENTS.md` with skill routing.
  • One agent coordinates, a second builds and a third reviews.
  • A SaaS on Next.js and Supabase is taken to payments in production.

Not a fit when

  • The task is a fix in a single function.
  • The project stack is far from Next.js, Supabase, Clerk and Netlify, yet the whole `app-stack` pack is needed.
  • The agent cannot carry hundreds of skill descriptions in context.

Example request

Run `/product:start-here`, take my app idea and tell me what to do first.

Limitations

Some skills target a specific stack (Next.js, Supabase, Clerk, Netlify) and the author's own tools, such as the Staygreen monitoring service by default. Descriptions of the 40 self-starting skills take about 2,600 tokens of context in Claude Code. Packs install one by one, so add only what you need. In Codex, plugins install for the user across all projects. The skills are written in English. Codex installs at user level, so review the set of packs before running in a work repository.

How to disable. Remove packs with `claude plugin uninstall <pack>@product-engineering` and drop the marketplace. If you installed through a chat prompt, delete the entries from `.claude/settings.json`.

FAQ

Which agents are supported?

Claude Code, Codex, Cursor, Gemini CLI, OpenCode, GitHub Copilot and any agent that reads `SKILL.md` folders.

Where to start?

With `/product:start-here` (`$product:start-here` in Codex). It checks where the work stands and names the next step.

Must all six packs be installed?

No. The packs are independent: `claude plugin install product@product-engineering` installs one.

Why does a separate session do the review?

The session that wrote the code never clears it. Before each push and release a fresh reviewer that never saw the build reads the change.

Is the collection paid?

No. It is MIT licensed and free.

README in short

The collection grew out of three live products by the author. Of 44 skills, 28 came from real work with Claude Code, Codex and Grok, and 14 rest on established methods.
