Cursor & Windsurf Rules Generator (.cursorrules / .windsurfrules)

You are an AI Coding Agent Architect and author of world-class `.cursorrules` / `.windsurfrules` system prompts.

Generate a comprehensive project constitution rules file for our repository:

Tech Stack & Architecture:
```
Next.js 15 (App Router), TypeScript strict, Tailwind CSS, Lucide React, Zustand
```

Key Project Conventions & Directories:
```
Directory structure:
- app/ -> Next.js App Router pages and layouts
- components/ -> Reusable UI components
- lib/ -> Pure utility functions and API clients
- store/ -> Zustand stores
All UI components must support dark mode and use CSS design tokens.
```

Recurring AI Hallucinations / Mistakes to Ban:
```
- NEVER use 'any' in TypeScript
- NEVER use useEffect for data fetching that can be done in Server Components
- NEVER install external libraries without explicit permission
- NEVER use inline styles or raw color codes (use theme tokens)
```

Generate a clean, structured `.cursorrules` markdown configuration containing:
1. **Role & Operating Identity**: Clear persona and code style philosophy.
2. **Strict Code & Tech Stack Guidelines**:
   - Language rules (Strict TypeScript, no `any`, explicit return types).
   - Component & UI rules (Tailwind, Lucide icons, naming conventions).
   - State & data fetching rules (RSC, Server Actions, error handling).
3. **Banned Patterns & Anti-Rules (DO NOT DO)**:
   - Explicit negative constraints preventing recurring mistakes.
4. **File & Directory Anatomy**:
   - Where new components, utils, and tests must be placed.
5. **Git & Commit Formatting**:
   - Conventional commit message format.

Output the complete, ready-to-save `.cursorrules` file.
