Launchpad

Build a template called Launchpad: a Next.js starter with auth, billing and an AGENTS.md your agent will follow.

What it does

Most starters are built for humans. Launchpad is built for you and your agent: auth, Stripe billing, emails and an admin panel, plus an AGENTS.md that explains the conventions so Claude Code, Codex or Cursor extend it the right way.

Stack

Use Next.js, Supabase, Stripe, Tailwind, shadcn/ui. The original was built with Claude Code in Ongoing, for about $90 in AI usage.

How it fits together

• A starter with auth, billing, email and an admin view
• An AGENTS.md that explains the conventions to coding agents
• Scripts that set up a new project in one command

Build it in this order

1. Pick the conventions and write them down first
2. Build auth, billing and email with tests
3. Add the admin view
4. Write AGENTS.md and try a feature using only it
5. Add a setup script and a short README

Tools to connect

• Supabase MCP: database and auth set-up
• Stripe MCP: products and webhooks

A prompt that worked: Write an AGENTS.md that works

Read the whole repo. Write an AGENTS.md under 150 lines that tells a coding agent: how to run, test and lint; where each kind of code lives; the five conventions that matter most here (with a file that shows each one); and what never to do. Then try a small task using only AGENTS.md as guidance and tell me what was missing.

Watch out for

• Every feature you add is something people must delete; keep it lean
• Agents follow AGENTS.md literally, so keep it short and concrete

Done when

• A new project is running in under ten minutes
• An agent can add a feature by following AGENTS.md
• Tests cover auth and billing

Before writing code, ask me up to five questions about who this engineering template is for and what the first version must do. Then work in small steps: after each one, tell me how to try it and wait for my feedback.
