## Quick Reference

### Tech Stack
- **Framework**: Next.js 15 with App Router
- **UI**: React 18, Tailwind CSS
- **Database**: MongoDB Atlas with Mongoose ODM
- **Authentication**: Clerk
- **State Management**: React Query, React Hooks
- **Validation**: Zod schemas

### Key Directories
- `src/app/` - Pages and layouts
- `src/app/actions/` - Server actions
- `src/components/` - Reusable components
- `src/lib/schema/mongoose-schema/` - Database models
- `src/lib/schema/zod-schema/` - Validation schemas
- `src/query/` - React Query hooks

## Animation Components

All animation components should be saved in:
```
src/app/animations/
```

### Available Animations
- `DilationAnimation.tsx` - Dilation transformation with scale factor slider

### Creating New Animations
1. Create component in `src/app/animations/`
2. Follow SVG-based patterns for math visualizations
3. Include proper TypeScript types
4. Support flexible configuration via props

## Code Patterns

### Server Action Pattern
```typescript
"use server";

export async function myAction(input: MyInputType) {
  return withDbConnection(async () => {
    try {
      const validated = MyInputSchema.parse(input);
      const result = await MyModel.findOne({ ... });
      return { success: true, data: result.toJSON() };
    } catch (error) {
      return { success: false, error: handleServerError(error, "Failed") };
    }
  });
}
```

### Component Pattern
```typescript
"use client";

import React from "react";

interface MyComponentProps {
  // Props with JSDoc comments
}

export function MyComponent({ ...props }: MyComponentProps) {
  return (
    // JSX
  );
}
```

## Key Principles

1. **Type Safety** - Use proper TypeScript types, avoid `any`
2. **Validation** - Use Zod for all external data
3. **Server First** - Prefer server components and actions
4. **React Query** - Use for server state management
5. **Component Hierarchy** - Follow core → composed → domain → features

## Integration with Other Skills

- For p5.js animations → Use `create-p5-animation` skill
- For database operations → See CLAUDE.md for mongosh patterns
