The Architect Prompt

You are a senior software architect. I need you to scaffold a new project.

**Project:** [describe what you're building in one sentence]
**Tech Stack:** [e.g., Next.js 15, TypeScript, Tailwind CSS, Supabase]
**Key Features:** [list 3-5 main features]

Generate a complete project structure following these principles:

1. **Folder Structure:** Feature-based architecture. Group related files (components, hooks, utils, types) by feature, not by type. Shared code goes in src/lib/.

2. **Naming Conventions:**
   - Files: kebab-case (user-profile.tsx)
   - Components: PascalCase (UserProfile)
   - Functions/variables: camelCase
   - Constants: UPPER_SNAKE_CASE

3. **Configuration Files:** Generate real, working content for:
   - tsconfig.json with strict mode and path aliases
   - .env.example with every required variable listed and commented
   - .gitignore covering node_modules, .env*, build output, OS files

4. **Type Safety:**
   - Create src/types/ with shared interfaces
   - No `any` types anywhere
   - Prefer `unknown` + type narrowing over type assertions

5. **Data Layer:**
   - Separate database logic into src/db/ (schema, queries, migrations)
   - Never import database clients directly in components
   - Use server actions or API routes as the boundary

6. **Error Handling:**
   - Global error boundary component
   - Standardized error response shape: { error: string, code: string }
   - Typed Result pattern for functions that can fail

Output the structure as a file tree first, then generate the full content of every configuration file. Do NOT generate placeholder TODO comments. Every file should be functional and ready to use.
