Premium Experience Skill

"One prompt. Complete app. Instant WOW."

Transform any idea into a premium, production-ready application with multiple pages, smooth animations, and zero errors - all in a single prompt.

🎯 Core Philosophy

PREMIUM = COMPLETE + POLISHED + DELIGHTFUL

User says: "Create expense tracker"

❌ Basic output:
   - 1 page
   - No animations
   - Basic styling
   - "Add more pages later"

✅ Premium output:
   - 5+ pages (Dashboard, Transactions, Reports, Settings, Auth)
   - Smooth page transitions
   - Micro-interactions everywhere
   - Loading skeletons
   - Empty states designed
   - Ready to use immediately

📱 Multi-Page Generation (MANDATORY!)

Page Generation Order

1. LAYOUT FIRST
   └── app/layout.tsx (with providers, fonts, metadata)
   └── components/layout/Navbar.tsx
   └── components/layout/Sidebar.tsx (if dashboard-style)
   └── components/layout/Footer.tsx (if marketing pages)

2. SHARED COMPONENTS
   └── components/ui/ (shadcn components)
   └── components/shared/ (app-specific shared)

3. FEATURE COMPONENTS
   └── components/features/[feature]/ (feature-specific)

4. PAGES (parallel if possible)
   └── app/page.tsx
   └── app/dashboard/page.tsx
   └── app/[feature]/page.tsx
   └── ...etc

5. AUTH PAGES (last)
   └── app/auth/login/page.tsx
   └── app/auth/register/page.tsx

✨ Animation System (MANDATORY!)

Required Animations

Every premium app MUST have these animations:

// 1. PAGE TRANSITIONS
// Every page should fade in smoothly

// components/motion/PageTransition.tsx
"use client";

import { motion } from "framer-motion";
import { ReactNode } from "react";

const pageVariants = {
  initial: { opacity: 0, y: 20 },
  animate: { opacity: 1, y: 0 },
  exit: { opacity: 0, y: -20 },
};

export function PageTransition({ children }: { children: ReactNode }) {
  return (
    <motion.div
      variants={pageVariants}
      initial="initial"
      animate="animate"
      exit="exit"
      transition={{ duration: 0.3, ease: "easeOut" }}
    >
      {children}
    </motion.div>
  );
}

// 2. STAGGERED LIST ANIMATIONS
// Lists should animate in one by one

// components/motion/StaggerContainer.tsx
"use client";

import { motion } from "framer-motion";
import { ReactNode } from "react";

const containerVariants = {
  hidden: { opacity: 0 },
  show: {
    opacity: 1,
    transition: {
      staggerChildren: 0.1,
    },
  },
};

const itemVariants = {
  hidden: { opacity: 0, y: 20 },
  show: { opacity: 1, y: 0 },
};

export function StaggerContainer({ children }: { children: ReactNode }) {
  return (
    <motion.div
      variants={containerVariants}
      initial="hidden"
      animate="show"
    >
      {children}
    </motion.div>
  );
}

export function StaggerItem({ children }: { children: ReactNode }) {
  return <motion.div variants={itemVariants}>{children}</motion.div>;
}

// 3. CARD HOVER EFFECTS
// Cards should lift on hover

// Usage in any card component
<motion.div
  whileHover={{ y: -4, boxShadow: "0 10px 40px -10px rgba(0,0,0,0.2)" }}
  transition={{ duration: 0.2 }}
  className="..."
>
  {/* Card content */}
</motion.div>

// 4. BUTTON PRESS EFFECTS
// Buttons should feel tactile

// Usage on buttons
<motion.button
  whileHover={{ scale: 1.02 }}
  whileTap={{ scale: 0.98 }}
  className="..."
>
  {children}
</motion.button>

// 5. NUMBER COUNTING ANIMATION
// Stats should count up

// components/motion/CountUp.tsx
"use client";

import { useEffect, useRef, useState } from "react";
import { useInView } from "framer-motion";

interface CountUpProps {
  end: number;
  duration?: number;
  prefix?: string;
  suffix?: string;
}

export function CountUp({ end, duration = 2, prefix = "", suffix = "" }: CountUpProps) {
  const [count, setCount] = useState(0);
  const ref = useRef(null);
  const isInView = useInView(ref, { once: true });

  useEffect(() => {
    if (!isInView) return;
    
    let startTime: number;
    const animate = (timestamp: number) => {
      if (!startTime) startTime = timestamp;
      const progress = Math.min((timestamp - startTime) / (duration * 1000), 1);
      setCount(Math.floor(progress * end));
      if (progress < 1) requestAnimationFrame(animate);
    };
    requestAnimationFrame(animate);
  }, [isInView, end, duration]);

  return <span ref={ref}>{prefix}{count.toLocaleString()}{suffix}</span>;
}

Animation Timing Guidelines

/* Standard timings */
--duration-fast: 150ms;      /* Micro-interactions */
--duration-normal: 200ms;    /* Button/hover states */
--duration-slow: 300ms;      /* Page transitions */
--duration-slower: 500ms;    /* Complex animations */

/* Easing functions */
--ease-out: cubic-bezier(0.33, 1, 0.68, 1);      /* Most animations */
--ease-in-out: cubic-bezier(0.65, 0, 0.35, 1);   /* Symmetric motion */
--ease-spring: cubic-bezier(0.34, 1.56, 0.64, 1); /* Playful bounce */

Animation Rules

DO:
✅ Use subtle animations (y: 20 max, scale: 1.02 max)
✅ Keep durations short (150-300ms)
✅ Use ease-out for most animations
✅ Animate on scroll (useInView)
✅ Stagger lists (100ms between items)

DON'T:
❌ Bounce animations (too playful)
❌ Long durations (>500ms feels slow)
❌ Large movements (y: 100+ is jarring)
❌ Animate everything (be selective)
❌ Block interaction during animation

🎨 Premium UI Components

Required Shared Components

Every premium app MUST have these components:

components/
├── layout/
│   ├── Navbar.tsx           # Responsive navigation
│   ├── Sidebar.tsx          # Dashboard sidebar (if applicable)
│   ├── Footer.tsx           # Marketing footer (if applicable)
│   └── MobileMenu.tsx       # Mobile navigation drawer
│
├── motion/

│
└── ui/                      # shadcn/ui components
    └── (generated by shadcn)

Loading State Pattern

// EVERY page should have loading state

// app/dashboard/loading.tsx
import { Skeleton } from "@/components/ui/skeleton";

export default function DashboardLoading() {
  return (
    <div className="space-y-6 p-6">
      {/* Stats skeleton */}
      <div className="grid grid-cols-4 gap-4">
        {[...Array(4)].map((_, i) => (
          <Skeleton key={i} className="h-32 rounded-xl" />
        ))}
      </div>
      
      {/* Chart skeleton */}
      <Skeleton className="h-64 rounded-xl" />
      
      {/* Table skeleton */}
      <div className="space-y-2">
        {[...Array(5)].map((_, i) => (
          <Skeleton key={i} className="h-12 rounded-lg" />
        ))}
      </div>
    </div>
  );
}

Empty State Pattern

// components/feedback/EmptyState.tsx
import { LucideIcon } from "lucide-react";
import { Button } from "@/components/ui/button";

interface EmptyStateProps {
  icon: LucideIcon;
  title: string;
  description: string;
  actionLabel?: string;
  onAction?: () => void;
}

export function EmptyState({
  icon: Icon,
  title,
  description,
  actionLabel,
  onAction,
}: EmptyStateProps) {
  return (
    <div className="flex flex-col items-center justify-center py-12 text-center">
      <div className="rounded-full bg-muted p-4 mb-4">
        <Icon className="h-8 w-8 text-muted-foreground" />
      </div>
      <h3 className="text-lg font-semibold mb-2">{title}</h3>
      <p className="text-muted-foreground mb-4 max-w-sm">{description}</p>
      {actionLabel && onAction && (
        <Button
      )}
    </div>
  );
}

🛡️ Zero Error Guarantee

TypeScript Strict Rules

// tsconfig.json MUST have these
{
  "compilerOptions": {
    "strict": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true
  }
}

Pre-Generation Checklist

Before generating ANY code, verify:

□ All imports are valid (no typos)
□ All types are defined
□ All props have types
□ No `any` type used
□ All async functions have error handling
□ All optional chaining where needed (?.)
□ All nullish coalescing where needed (??)
□ All arrays initialized before use
□ All state has initial values

Common Error Prevention Patterns

// ❌ BAD: Will error if data is undefined
{data.items.map(item => ...)}

// ✅ GOOD: Safe with fallback
{(data?.items ?? []).map(item => ...)}

// ❌ BAD: Type error on undefined
function UserCard({ user }) { ... }

// ✅ GOOD: Proper typing
interface UserCardProps {
  user: User;
}
function UserCard({ user }: UserCardProps) { ... }

// ❌ BAD: Unhandled async
const data = await fetch(...);

// ✅ GOOD: With error handling
try {
  const data = await fetch(...);
  if (!data.ok) throw new Error('Failed to fetch');
  return data.json();
} catch (error) {
  console.error('Fetch error:', error);
  return null;
}

Required Type Definitions

Every project MUST have:

// types/index.ts
export interface User {
  id: string;
  name: string;
  email: string;
  avatar?: string;
  createdAt: Date;
}

// types/[feature].ts
export interface [Feature] {
  id: string;
  // ... feature-specific fields
  createdAt: Date;
  updatedAt: Date;
}

// types/api.ts
export interface ApiResponse<T> {
  data: T;
  error?: string;
  message?: string;
}

export interface PaginatedResponse<T> {
  data: T[];
  total: number;
  page: number;
  pageSize: number;
  hasMore: boolean;
}
