Build Supastarter App

Use this skill when the user is changing a real Supastarter monorepo and the answer must follow repo-specific patterns instead of generic Next.js or SaaS boilerplate.

Use this skill for

• adding or moving marketing pages, SaaS pages, layouts, or redirects
• creating or wiring oRPC procedures, routers, and client query usage
• changing login, signup, onboarding, invitations, sessions, or organization flows
• adding schema, query, billing, checkout, portal, webhook, or upload behavior
• placing files in the right app, module, or package inside the monorepo

Do not use this skill for

• generic TypeScript quality work with no Supastarter-specific patterns; use develop-typescript
• pull request review or review-only work; use review-pr
• framework-agnostic Next.js advice that ignores this repo's routing, guards, and package boundaries
