Usage Example
User: "Make an Instagram clone with photo sharing and likes"
App Builder Process:
1. Project type: Social Media App
2. Tech stack: Next.js + Prisma + Cloudinary + Clerk
3. Create plan:
├─ Database schema (users, posts, likes, follows)
├─ API routes (12 endpoints)
├─ Pages (feed, profile, upload)
└─ Components (PostCard, Feed, LikeButton)
4. Coordinate agents
5. Report progress
6. Start preview

App Builder analyzes natural language requests to determine the project type, selects the tech stack, plans the project structure, and coordinates multiple agents to deliver full-stack applications. It relies on selective reading of content maps and templates to create scalable scaffolds and MVPs. This speeds up project initiation while standardizing architecture across teams.
How This Skill Works
The tool parses the user request, uses project-detection rules to identify the project type, and selects a tech stack from the tech-stack guidance. It then creates a plan and coordinates specialized agents (frontend, backend, database, devops) to implement features, APIs, and scaffolding, referencing relevant files like scaffolding.md and agent-coordination.md to execute tasks.
When to Use It
- Starting a new project from natural language input.
- Choosing an appropriate tech stack for a given idea.
- Scaffolding project structure and core files for a fresh build.
- Coordinating multiple agents to implement features across frontend, backend, and deployment.
- Producing a runnable preview or MVP from a high-level concept.
Quick Start
- Step 1: Parse the user request to classify the project type and goals.
- Step 2: Select a tech stack and plan the architecture using project-detection and tech-stack guidance.
- Step 3: Scaffold the project, coordinate agents, and launch a preview.
Best Practices
- Provide a clear natural language brief with core features and desired outcomes.
- Reference a matching template when possible to constrain scope.
- Let App Builder propose a plan before scaffolding begins.
- Validate the generated architecture against requirements and desired tech stack.
- Use iterative reviews and progress reports to adjust scope and milestones.
Example Use Cases
- Instagram clone with photo sharing and likes using Next.js + Prisma.
- SaaS product with Next.js + Stripe integration.
- REST API server built with Express and JWT authentication.
- Mobile app built with React Native (Expo) and Zustand for state management.
- Desktop app using Electron with a React frontend.
