About

Interview the user in depth about what they actually want to build, then scaffold a working full-stack web app around it. Use when the user wants to start a new app, website, prototype, or SaaS; when they don't know what tech stack to pick; or when they want a solid working starting point fast. Covers requirements discovery, project setup, database (SQLite or Postgres in Docker), sign-in, transactional email, file uploads, payments, AI features, background jobs, optional agent access over MCP so tools like Claude can use the app, a real landing page and dashboard, optional public help documentation, a design system agreed with the user and written to DESIGN.md so every page matches, an account settings area with system logs and debugging built in, the legal pages and cookie consent an app of that kind actually owes its users, whether search engines and AI crawlers should find it at all, and a closing pass that proves the result actually builds, serves and does what was agreed rather than taking the builder's word for it.

Use cases: documents, design, frontend, backend
