v0.6.0

Ship products,
not boilerplate.

One command to scaffold a production-ready monorepo with auth, billing, and CI/CD — wired and ready to deploy.

$ pnpm dlx @yabbal/coldstart init

Official CLIs

create-next-app, create-expo-app do the heavy lifting. Coldstart only writes the glue code.

Deterministic

Every run outputs a .coldstart.json. Same config, same result — verified with hashes.

AI-guided

Generates CLAUDE.md, installs skills, configures MCP servers. Your AI knows the full context.

Claude Code skill

Coldstart is also a Claude Code skill. Type /coldstart in Claude Code and the AI handles everything — from scaffolding to database setup, deployment, and billing configuration. No terminal, no docs, no context switching.

Scaffold via AI

Describe your project in plain language. Claude runs the CLI, installs dependencies, initializes git, and sets up skills and MCP servers automatically.

Deploy via AI

After scaffolding, Claude walks you through infrastructure setup — Neon database, Vercel deployment, Polar billing, Resend emails — all conversationally.

Context-aware from day one

The generated CLAUDE.md gives Claude full understanding of your architecture, domain rules, billing model, and conventions. No onboarding needed.

MCP servers pre-wired

Neon, Vercel, Polar, RevenueCat, Resend, Expo — Claude interacts with all your services directly through MCP. Stripe projects get full checkout and portal setup.

# Install the skill
$ npx skills add yabbal/cold-start

# Then in Claude Code, just type:
> /coldstart

Get started

Run the CLI directly, or let Claude Code do it for you.
