App Builder

This is the orchestrator that takes "build me X" and turns it into a working application. It detects project type from your request, picks a modern tech stack from 13 templates (Next.js full-stack, FastAPI, React Native, Chrome extensions, etc.), then coordinates specialized agents to handle frontend, backend, database, and deployment. The selective reading approach is smart: it only loads relevant template files instead of everything at once. Works best when you describe what you want to build rather than how to build it. The real value is in the coordination layer and the opinionated 2025 tech stacks, though you'll want to review its choices before committing to a specific architecture.
