+type: guardrail
+enforcement: block
+---
+
+# Next.js eCommerce Development Guidelines
+
+**PURPOSE**: Enforce consistent patterns, DRY principles, SRP, design token usage, and Component.module.css styling across the Next.js + WooCommerce eCommerce application.
+
+## Core Principles
+
+### 1. DRY (Don't Repeat Yourself)
+- Reuse foundational components (Button, Card, Input, Form, Table, Modal)
+- Extract repeated logic into custom hooks
+- Create utility functions for common operations
+- Use TypeScript generics for type reusability
+
+### 2. SRP (Single Responsibility Principle)
+- Each component has ONE clear purpose
+- Features directory for domain-specific logic
+- Components directory for truly reusable UI elements
+- Separation of concerns: UI, business logic, data fetching
+
+### 3. NO Inline Styles
+**CRITICAL RULE**: NO hardcoded colors, spacing, or design values in components.
+
+❌ **FORBIDDEN**:
+```tsx
+<div style={{ color: '#2196f3', padding: '16px' }}>
+```
+
+✅ **REQUIRED**:
+```tsx
+<div className={styles.container}>
+```
+
+```css
+/* Component.module.css */
+.container {
+  color: var(--color-primary-600);
+  padding: var(--spacing-4);
+}
+```
+
+### 4. Design Tokens Only
+ALL styling values MUST come from design tokens defined in `src/styles/tokens.css`.
+
+**Available token categories**:
+- Colors: `--color-primary-500`, `--color-text-primary`, etc.
+- Spacing: `--spacing-4`, `--spacing-6`, etc.
+- Typography: `--font-size-base`, `--font-weight-medium`, etc.
+- Borders: `--border-radius-md`, `--border-width-thin`, etc.
+- Shadows: `--shadow-md`, `--shadow-lg`, etc.
+- Transitions: `--transition-base`, etc.
+
+## File Organization
+
+### Project Structure
+
+```
+src/
+  app/                    # Next.js App Router pages
+    page.tsx
+    layout.tsx
+    products/
+      page.tsx
+      [id]/page.tsx
+
+  components/             # Reusable UI components

+      Button.tsx
+      Button.module.css
+      index.ts
+    Card/
+    Input/
+    Modal/
+    Form/
+    Table/
+
+  features/               # Domain-specific features
+    products/
+      api/                # API service layer
+        productsApi.ts
+      components/         # Feature-specific components
+        ProductCard.tsx
+        ProductCard.module.css
+        ProductGrid.tsx
+      hooks/              # Custom hooks
+        useProducts.ts
+      types/              # TypeScript types
+        index.ts
+
+  lib/                    # Shared libraries

+      client.ts
+      types.ts
+    stripe/
+      client.ts
+    utils/
+
+  hooks/                  # App-level hooks
+    useCart.ts
+
+  types/                  # Global types
+
+  styles/                 # Global styles & tokens
+    tokens.css
+    globals.css
+    tokens.ts
+```
+
+### When to use features/ vs components/
+
+**Use `features/` when**:
+- Component is specific to a business domain (products, orders, customers)
+- Tightly coupled to specific data structures
+- Contains business logic
+- Used in specific contexts
+
+**Use `components/` when**:
+- Component is truly reusable across the app
+- No business logic
+- Pure UI component
+- Used in 3+ different places
+
+## Component Patterns
+
+### Component Structure
+
+Every component MUST follow this pattern:
+
+```tsx
+/**
+ * ComponentName Component
+ *
+ * Clear description of what this component does.
+ *
+ * @example
+ * ```tsx
+ * <ComponentName prop1="value" onAction={handler} />
+ * ```
+ */
+
+'use client'; // Only if using client features
+
+import React from 'react';
+import type { ReactNode } from 'react';
+import styles from './ComponentName.module.css';
+
+export interface ComponentNameProps {
+  /** Prop description */
+  prop1: string;
+  /** Optional prop */
+  prop2?: number;
+  /** Event handler */
+  onAction?: () => void;
+  children?: ReactNode;
+}
+
+export const ComponentName: React.FC<ComponentNameProps> = ({
+  prop1,
+  prop2 = 0,
+  onAction,
+  children,
+}) => {
+  // Component logic here
+
+  return (
+    <div className={styles.container}>
+      {children}
+    </div>
+  );
+};
+
+export default ComponentName;
+```
+
+### CSS Module Structure
+
+Every `Component.module.css` MUST follow this pattern:
+
+```css
+/**
+ * ComponentName Component Styles
+ *
+ * RULES:
+ * - All values MUST use design tokens from tokens.css
+ * - NO hardcoded colors, spacing, or other values
+ * - Maintain consistent UX across all instances
+ */
+
+.container {
+  display: flex;
+  flex-direction: column;
+  gap: var(--spacing-4);
+  padding: var(--spacing-6);
+  background-color: var(--color-background);
+  border-radius: var(--border-radius-lg);
+}
+
+.title {
+  font-size: var(--font-size-xl);
+  font-weight: var(--font-weight-semibold);
+  color: var(--color-text-primary);
+  margin: 0;
+}
+
+/* Responsive */
+@media (max-width: 768px) {
+  .container {
+    padding: var(--spacing-4);
+  }
+}
+```
+
+## TypeScript Standards
+
+### Type Definitions
+
+```tsx
+// ✅ GOOD: Explicit prop types with JSDoc
+export interface ButtonProps {
+  /** Button visual variant */
+  variant?: 'primary' | 'secondary' | 'outline';
+  /** Button size */
+  size?: 'sm' | 'md' | 'lg';
+  /** Click handler */
+  onClick?: () => void;
+  children: ReactNode;
+}
+
+// ❌ BAD: No documentation
+interface Props {
+  variant?: string;
+  size?: string;
+  onClick?: any;
+}
+```
+
+### Path Aliases
+
+Use configured path aliases for imports:
+
+```tsx
+// ✅ GOOD
+import { Button } from '~components/Button';
+import { Product } from '~features/products/types';
+import { formatPrice } from '~lib/utils';
+
+// ❌ BAD
+import { Button } from '../../../components/Button';
+```
+
+## Data Fetching Patterns
+
+### API Routes (Server-Side)
+
+```tsx
+// app/api/products/route.ts
+import { NextResponse } from 'next/server';
+import { getWooCommerceClient } from '~lib/woocommerce';
+
+export async function GET(request: Request) {
+  try {
+    const wc = getWooCommerceClient();
+    const { data } = await wc.getProducts();
+
+    return NextResponse.json(data);
+  } catch (error) {
+    return NextResponse.json(
+      { error: 'Failed to fetch products' },
+      { status: 500 }
+    );
+  }
+}
+```
+
+### Client-Side Service Layer
+
+```tsx
+// features/products/api/productsApi.ts
+export const getProducts = async (): Promise<Product[]> => {
+  const response = await fetch('/api/products');
+
+  if (!response.ok) {
+    throw new Error('Failed to fetch products');
+  }
+
+  return response.json();
+};
+```
+
+### Custom Hooks
+
+```tsx
+// features/products/hooks/useProducts.ts
+'use client';
+
+import { useState, useEffect } from 'react';
+import { getProducts } from '../api/productsApi';
+import type { Product } from '../types';
+
+export const useProducts = () => {
+  const [products, setProducts] = useState<Product[]>([]);
+  const [loading, setLoading] = useState(true);
+  const [error, setError] = useState<string | null>(null);
+
+  useEffect(() => {
+    const fetchProducts = async () => {
+      try {
+        setLoading(true);
+        const data = await getProducts();
+        setProducts(data);
+      } catch (err) {
+        setError(err instanceof Error ? err.message : 'Unknown error');
+      } finally {
+        setLoading(false);
+      }
+    };
+
+    fetchProducts();
+  }, []);
+
+  return { products, loading, error };
+};
+```
+
+## Form Handling
+
+Use the Form foundational component:
+
+```tsx
+<Form onSubmit={handleSubmit} error={formError}>
+  <FormGroup>
+    <Input
+      label="Email"
+      type="email"
+      required
+      value={email}
+      onChange={(e) => setEmail(e.target.value)}
+    />
+    <Input
+      label="Password"
+      type="password"
+      required
+      value={password}
+      onChange={(e) => setPassword(e.target.value)}
+    />
+  </FormGroup>
+
+  <FormActions>
+    <Button type="button" variant="outline" onClick={onCancel}>
+      Cancel
+    </Button>
+    <Button type="submit" loading={isSubmitting}>
+      Submit
+    </Button>
+  </FormActions>
+</Form>
+```
+
+## WooCommerce Integration
+
+### Server-Side Only
+
+WooCommerce API credentials MUST never be exposed to the client:
+
+```tsx
+// ✅ GOOD: API Route (server-side)
+import { getWooCommerceClient } from '~lib/woocommerce';
+
+export async function GET() {
+  const wc = getWooCommerceClient();
+  const products = await wc.getProducts();
+  return NextResponse.json(products);
+}
+
+// ❌ BAD: Client component
+'use client';
+const wc = getWooCommerceClient(); // This will throw error!
+```
+
+### Type Mapping
+
+Map WooCommerce types to simplified frontend types:
+
+```tsx
+// lib/woocommerce/mappers.ts
+export const mapWooProductToProduct = (
+  wooProduct: WooCommerceProduct
+): Product => ({
+  id: wooProduct.id,
+  name: wooProduct.name,
+  price: parseFloat(wooProduct.price),
+  regularPrice: parseFloat(wooProduct.regular_price),
+  salePrice: wooProduct.sale_price ? parseFloat(wooProduct.sale_price) : null,
+  // ... map other fields
+});
+```
+
+## Error Handling
+
+Always handle errors gracefully:
+
+```tsx
+try {
+  const data = await fetchData();
+  setData(data);
+} catch (error) {
+  const message = error instanceof Error ? error.message : 'Unknown error';
+  setError(message);
+  console.error('Failed to fetch data:', error);
+}
+```
+
+## Performance
+
+### Image Optimization
+
+Always use Next.js Image component:
+
+```tsx
+import Image from 'next/image';
+
+<Image
+  src={product.image}
+  alt={product.name}
+  width={300}
+  height={300}
+  sizes="(max-width: 768px) 100vw, 50vw"
+/>
+```
+
+### Code Splitting
+
+Use dynamic imports for heavy components:
+
+```tsx
+import dynamic from 'next/dynamic';
+
+const HeavyComponent = dynamic(() => import('./HeavyComponent'), {
+  loading: () => <div>Loading...</div>,
+});
+```
+
+## Accessibility
+
+- Use semantic HTML
+- Provide alt text for images
+- Ensure keyboard navigation works
+- Use ARIA labels where needed
+- Test with screen readers
+
+## Testing Checklist
+
+Before committing:
+
+✅ No inline styles
+✅ All design tokens used correctly
+✅ TypeScript types defined
+✅ Components follow structure pattern
+✅ CSS modules use tokens only
+✅ No WooCommerce/Stripe keys on client
+✅ Error handling in place
+✅ Responsive design tested
+✅ Accessibility checked
+
+## Common Mistakes to Avoid
+
+1. ❌ Hardcoded colors/spacing
+2. ❌ Inline styles
+3. ❌ Exposing API credentials to client
+4. ❌ Missing TypeScript types
+5. ❌ Not using foundational components
+6. ❌ Mixing business logic in UI components
+7. ❌ Not using path aliases
+8. ❌ Missing error handling
+9. ❌ No responsive design
+10. ❌ Poor accessibility
+

+
+**Remember**: Consistency is key. Follow these patterns strictly to maintain a clean, maintainable codebase.

+# From the showcase repository
+cp -r nextjs-ecommerce-template/* your-project-name/
+cd your-project-name
+```
+
+### 2. Install Dependencies
+
+```bash
+npm install
+```
+
+### 3. Configure Environment Variables
+
+```bash
+cp .env.example .env.local
+```
+
+Edit `.env.local` with your credentials:
+
+```env
+# Site Configuration
+NEXT_PUBLIC_SITE_URL=http://localhost:3000
+
+# WooCommerce Configuration
+NEXT_PUBLIC_WOOCOMMERCE_URL=https://your-woocommerce-site.com
+WOOCOMMERCE_CONSUMER_KEY=your_consumer_key
+WOOCOMMERCE_CONSUMER_SECRET=your_consumer_secret
+
+# Stripe Configuration
+NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=your_publishable_key
+STRIPE_SECRET_KEY=your_secret_key
+STRIPE_WEBHOOK_SECRET=your_webhook_secret
+```
+
+### 4. Run Development Server
+
+```bash
+npm run dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) to see your application.
+
+## 🎨 Design Token System
+
+All styling MUST use design tokens from `src/styles/tokens.css`.
+
+### Available Tokens
+
+```css
+/* Colors */
+--color-primary-500
+--color-secondary-600
+--color-success-500
+--color-error-600
+--color-text-primary
+--color-background
+
+/* Spacing */
+--spacing-1  /* 4px */
+--spacing-4  /* 16px */
+--spacing-6  /* 24px */
+
+/* Typography */
+--font-size-base
+--font-weight-medium
+
+/* And many more... */
+```
+
+### Usage Example
+
+```css
+/* Component.module.css */
+.button {
+  padding: var(--spacing-2) var(--spacing-4);
+  background-color: var(--color-primary-600);
+  color: white;
+  border-radius: var(--border-radius-md);
+  font-size: var(--font-size-base);
+  transition: var(--transition-base);
+}
+
+.button:hover {
+  background-color: var(--color-primary-700);
+}
+```
+
+❌ **NEVER DO THIS**:
+```css
+.button {
+  padding: 8px 16px;        /* Hardcoded! */
+  background-color: #2196f3; /* Hardcoded! */
+}
+```
+
+## 🧩 Foundational Components
+
+Use these everywhere instead of creating new ones:
+
+### Button
+
+```tsx
+import { Button } from '~components/Button';
+
+<Button variant="primary" size="md" onClick={handleClick}>
+  Click Me
+</Button>
+```
+
+### Card
+
+```tsx
+import { Card, CardHeader, CardBody, CardFooter } from '~components/Card';
+
+<Card variant="elevated" padding="md">
+  <CardHeader>Title</CardHeader>
+  <CardBody>Content</CardBody>
+  <CardFooter>Footer</CardFooter>
+</Card>
+```
+
+### Input
+
+```tsx
+import { Input } from '~components/Input';
+
+<Input
+  label="Email"
+  type="email"
+  required
+  error={errors.email}
+  value={email}
+  onChange={(e) => setEmail(e.target.value)}
+/>
+```
+
+### Form
+
+```tsx
+import { Form, FormGroup, FormActions } from '~components/Form';
+
+<Form onSubmit={handleSubmit} error={error}>
+  <FormGroup>
+    <Input label="Email" type="email" />
+    <Input label="Password" type="password" />
+  </FormGroup>
+  <FormActions>
+    <Button type="submit">Submit</Button>
+  </FormActions>
+</Form>
+```
+
+### Modal
+
+```tsx
+import { Modal, ModalBody, ModalFooter } from '~components/Modal';
+
+<Modal open={isOpen} onClose={handleClose} title="Confirm">
+  <ModalBody>Are you sure?</ModalBody>
+  <ModalFooter>
+    <Button variant="outline" onClick={handleClose}>Cancel</Button>
+    <Button variant="primary" onClick={handleConfirm}>Confirm</Button>
+  </ModalFooter>
+</Modal>
+```
+
+### Table
+
+```tsx
+import { Table } from '~components/Table';
+
+<Table
+  columns={[
+    { key: 'name', label: 'Name', sortable: true },
+    { key: 'price', label: 'Price', align: 'right' }
+  ]}
+  data={products}
+  striped
+  hoverable
+/>
+```
+
+## 🏗️ Creating New Features
+
+### Feature Structure
+
+```
+features/
+  your-feature/
+    api/
+      yourFeatureApi.ts      # API service layer
+    components/
+      YourComponent.tsx      # Feature-specific components
+      YourComponent.module.css
+    hooks/
+      useYourFeature.ts      # Custom hooks
+    types/
+      index.ts               # TypeScript types
+```
+
+### Example: Creating a "Cart" Feature
+
+1. **Create directory structure**
+
+```bash
+mkdir -p src/features/cart/{api,components,hooks,types}
+```
+
+2. **Define types** (`src/features/cart/types/index.ts`)
+
+```tsx
+export interface CartItem {
+  productId: number;
+  quantity: number;
+  price: number;
+}
+
+export interface Cart {
+  items: CartItem[];
+  total: number;
+}
+```
+
+3. **Create API service** (`src/features/cart/api/cartApi.ts`)
+
+```tsx
+export const addToCart = async (productId: number): Promise<Cart> => {
+  const response = await fetch('/api/cart', {
+    method: 'POST',
+    body: JSON.stringify({ productId }),
+  });
+  return response.json();
+};
+```
+
+4. **Create custom hook** (`src/features/cart/hooks/useCart.ts`)
+
+```tsx
+'use client';
+
+export const useCart = () => {
+  const [cart, setCart] = useState<Cart | null>(null);
+
+  const addItem = async (productId: number) => {
+    const updatedCart = await addToCart(productId);
+    setCart(updatedCart);
+  };
+
+  return { cart, addItem };
+};
+```
+
+5. **Create components** with `.module.css` files
+
+## 🔌 WooCommerce Integration
+
+### Server-Side Only
+
+WooCommerce API credentials MUST only be used server-side:
+
+```tsx
+// app/api/products/route.ts (✅ CORRECT)
+import { getWooCommerceClient } from '~lib/woocommerce';
+
+export async function GET() {
+  const wc = getWooCommerceClient();
+  const products = await wc.getProducts();
+  return NextResponse.json(products);
+}
+```
+
+### Client-Side API Calls
+
+```tsx
+// features/products/api/productsApi.ts (✅ CORRECT)
+export const getProducts = async (): Promise<Product[]> => {
+  const response = await fetch('/api/products');
+  return response.json();
+};
+```
+
+## 💳 Stripe Integration
+
+### Create Payment Intent (Server-Side)
+
+```tsx
+// app/api/create-payment-intent/route.ts
+import { createPaymentIntent } from '~lib/stripe/client';
+
+export async function POST(request: Request) {
+  const { amount } = await request.json();
+
+  const paymentIntent = await createPaymentIntent(amount, 'usd');
+
+  return NextResponse.json({
+    clientSecret: paymentIntent.client_secret,
+  });
+}
+```
+
+## 📝 Claude Code Skill
+
+The template includes a Claude Code skill that enforces all patterns.
+
+### Activation
+
+The skill automatically activates when:
+- Editing `.tsx` or `.ts` files in `src/`
+- Creating new components
+- Working with styling
+
+### What It Enforces
+
+- ✅ No inline styles
+- ✅ Design tokens usage
+- ✅ Component structure patterns
+- ✅ TypeScript types
+- ✅ File organization
+- ✅ DRY and SRP principles
+
+### Skill Location
+
+`.claude/skills/nextjs-ecommerce-guidelines/SKILL.md`
+
+## 🧪 Development Workflow
+
+### Before Creating a Component
+
+1. Check if a foundational component exists
+2. If not, check if it belongs in `features/` or `components/`
+3. Follow the component structure pattern
+4. Create both `.tsx` and `.module.css` files
+
+### Component Checklist
+
+- ✅ TypeScript props interface with JSDoc
+- ✅ Proper exports (named + default)
+- ✅ CSS module with design tokens only
+- ✅ No inline styles
+- ✅ Responsive design
+- ✅ Accessibility (ARIA labels, semantic HTML)
+
+### Before Committing
+
+```bash
+# Type check
+npm run type-check
+
+# Lint
+npm run lint
+
+# Format
+npm run format
+```
+
+## 🎯 Path Aliases
+
+Use configured aliases for cleaner imports:
+
+```tsx
+import { Button } from '~components/Button';
+import { Product } from '~features/products/types';
+import { formatPrice } from '~lib/utils';
+import { useCart } from '~hooks/useCart';
+```
+
+## 📚 Examples
+
+### Product Card (Full Example)
+
+See `src/features/products/components/ProductCard.tsx` for a complete example demonstrating:
+- Foundational component usage (Card, Button)
+- Design token styling
+- TypeScript types
+- Event handling
+- Responsive design
+
+### Product Grid
+
+See `src/features/products/components/ProductGrid.tsx` for grid layout patterns.
+
+## 🚨 Common Mistakes
+
+### ❌ Don't Do This
+
+```tsx
+// Inline styles
+<div style={{ color: 'blue', padding: 16 }}>
+
+// Hardcoded values in CSS
+.button {
+  padding: 16px;
+  color: #2196f3;
+}
+
+// WooCommerce on client
+'use client';
+const wc = getWooCommerceClient(); // ERROR!
+
+// Missing types
+function MyComponent(props) {  // No types!
+```
+
+### ✅ Do This Instead
+
+```tsx
+// CSS module with tokens
+<div className={styles.container}>
+
+// Design tokens
+.button {
+  padding: var(--spacing-4);
+  color: var(--color-primary-600);
+}
+
+// WooCommerce in API route
+export async function GET() {
+  const wc = getWooCommerceClient();
+}
+
+// Proper types
+interface MyComponentProps {
+  name: string;
+}
+export const MyComponent: React.FC<MyComponentProps> = ({ name }) => {
+```
+
+## 🔧 Customization
+
+### Modify Design Tokens
+
+Edit `src/styles/tokens.css` to customize the design system:
+
+```css
+:root {
+  --color-primary-600: #your-brand-color;
+  --spacing-4: 1rem;
+  /* ... */
+}
+```
+
+All components will automatically update!
+
+### Add New Foundational Components
+
+1. Create in `src/components/NewComponent/`
+2. Follow Button/Card patterns
+3. Use design tokens exclusively
+4. Export via `index.ts`

+
+## Your First Steps
+
+### 1. Create Your First Page
+
+```bash
+# Create a products listing page
+touch src/app/products/page.tsx
+```
+
+```tsx
+// src/app/products/page.tsx
+import { ProductGrid } from '~features/products/components';
+
+export default function ProductsPage() {
+  return (
+    <div className="container">
+      <h1>Products</h1>
+      <ProductGrid products={[]} />
+    </div>
+  );
+}
+```
+
+### 2. Create Your First API Route
+
+```bash
+# Create products API route
+mkdir -p src/app/api/products
+touch src/app/api/products/route.ts
+```
+
+```tsx
+// src/app/api/products/route.ts
+import { NextResponse } from 'next/server';
+import { getWooCommerceClient } from '~lib/woocommerce';
+
+export async function GET() {
+  try {
+    const wc = getWooCommerceClient();
+    const { data } = await wc.getProducts();
+
+    return NextResponse.json(data);
+  } catch (error) {
+    return NextResponse.json(
+      { error: 'Failed to fetch products' },
+      { status: 500 }
+    );
+  }
+}
+```
+
+### 3. Create Your First Feature
+
+Let's create a "Cart" feature:
+
+```bash
+# Create directory structure
+mkdir -p src/features/cart/{api,components,hooks,types}
+```
+
+**Types** (`src/features/cart/types/index.ts`):
+
+```tsx
+export interface CartItem {
+  productId: number;
+  quantity: number;
+  price: number;
+}
+```
+
+**Hook** (`src/features/cart/hooks/useCart.ts`):
+
+```tsx
+'use client';
+
+import { useState } from 'react';
+import type { CartItem } from '../types';
+
+export const useCart = () => {
+  const [items, setItems] = useState<CartItem[]>([]);
+
+  const addItem = (item: CartItem) => {
+    setItems([...items, item]);
+  };
+
+  return { items, addItem };
+};
+```
+
+**Component** (`src/features/cart/components/CartIcon.tsx`):
+
+```tsx
+'use client';
+
+import React from 'react';
+import { useCart } from '../hooks/useCart';
+import styles from './CartIcon.module.css';
+
+export const CartIcon: React.FC = () => {
+  const { items } = useCart();
+
+  return (
+    <div className={styles.cartIcon}>
+      🛒 {items.length}
+    </div>
+  );
+};
+```
+
+**Styles** (`src/features/cart/components/CartIcon.module.css`):
+
+```css
+.cartIcon {
+  display: flex;
+  align-items: center;
+  gap: var(--spacing-2);
+  padding: var(--spacing-2);
+  background-color: var(--color-primary-600);
+  color: white;
+  border-radius: var(--border-radius-md);
+  font-weight: var(--font-weight-medium);
+}
+```
+

+
+1. **Check if foundational component exists first!**
+2. Decide: `components/` (reusable) or `features/` (domain-specific)?
+3. Create both `.tsx` and `.module.css` files
+4. Use design tokens exclusively
+5. Export via `index.ts`
+
+### Component Template
+
+```tsx
+/**
+ * ComponentName Component
+ *
+ * Description
+ */
+
+import React from 'react';
+import type { ReactNode } from 'react';
+import styles from './ComponentName.module.css';
+
+export interface ComponentNameProps {
+  children: ReactNode;
+}
+
+export const ComponentName: React.FC<ComponentNameProps> = ({
+  children,
+}) => {
+  return (
+    <div className={styles.container}>
+      {children}
+    </div>
+  );
+};
+
+export default ComponentName;
+```
+
+### CSS Module Template
+
+```css
+/**
+ * ComponentName Styles
+ *
+ * RULES:
+ * - All values MUST use design tokens
+ * - NO hardcoded values
+ */
+
+.container {
+  display: flex;
+  gap: var(--spacing-4);
+  padding: var(--spacing-6);
+  background-color: var(--color-background);
+  border-radius: var(--border-radius-lg);
+}
+```
+
+## Customization
+
+### Change Brand Colors
+
+Edit `src/styles/tokens.css`:
+
+```css
+:root {
+  /* Change primary color */
+  --color-primary-500: #your-color;
+  --color-primary-600: #your-darker-color;
+  --color-primary-700: #your-even-darker-color;
+}
+```
+
+All components update automatically!
+
+### Add New Spacing Values
+
+```css
+:root {
+  --spacing-32: 8rem;  /* 128px */
+}
+```
+
+### Extend Typography
+
+```css
+:root {
+  --font-size-6xl: 4rem;  /* 64px */
+}
+```
+
+## Troubleshooting
+
+### WooCommerce Connection Issues
+
+```bash
+# Test your credentials
+curl -u "ck_xxxxx:cs_xxxxx" \
+  https://your-store.com/wp-json/wc/v3/products
+```
+
+### TypeScript Errors
+
+```bash
+# Clear and rebuild
+rm -rf .next node_modules
+npm install
+npm run dev
+```
+
+### Module Not Found
+
+Check your `tsconfig.json` paths match your imports:
+
+```json
+{
+  "paths": {
+    "@/*": ["./src/*"],
+    "~components/*": ["./src/components/*"]
+  }
+}
+```
+
+## Next Steps
+
+1. ✅ Set up WooCommerce connection
+2. ✅ Configure Stripe
+3. ✅ Create your first feature
+4. ✅ Build product listing page
+5. ✅ Implement cart functionality
+6. ✅ Create checkout flow
+7. ✅ Add authentication
+8. ✅ Deploy to production
+
+## Deployment
+
+### Vercel (Recommended)
+
+```bash
+# Install Vercel CLI
+npm i -g vercel
+
+# Deploy
+vercel
+
+# Set environment variables in Vercel dashboard
+```
+
+### Build for Production
+
+```bash
+npm run build
+npm start
+```

+# Claude Code Skills
+
+This directory contains Claude Code skills that automatically enforce development patterns and best practices.
+
+## Installed Skills
+
+### nextjs-ecommerce-guidelines
+
+**Purpose**: Enforces Next.js eCommerce development patterns including DRY, SRP, no inline styles, and design token usage.
+
+**Auto-Activation Triggers**:
+
+1. **Keywords**: When you mention:
+   - component, create component, new component
+   - style, styling, css, design
+   - button, card, form, input, modal, table
+   - woocommerce, product, cart, checkout
+
+2. **File Patterns**: When you edit:
+   - Any `.tsx` or `.ts` file in `src/`
+   - Any `.css` file (especially `.module.css`)
+   - Files in `src/components/` or `src/features/`
+
+3. **Code Patterns**: When your code contains:
+   - `import ... from '~components/...'`
+   - `className=`
+   - `styles.`
+   - `React.FC`
+
+## How It Works
+
+### Automatic Activation
+
+You **don't need to manually load the skill**. When you:
+
+```
+You: "Let's create a new ProductCard component"
+```
+
+Claude automatically loads the skill and will:
+- ✅ Enforce Component.module.css pattern
+- ✅ Require design tokens (no hardcoded values)
+- ✅ Ensure TypeScript types
+- ✅ Follow the component structure pattern
+- ✅ Block inline styles
+
+### Enforcement Level
+
+The skill has `"enforcement": "block"` which means:
+- Claude will **require** following the patterns
+- You'll see warnings if attempting non-compliant patterns
+- The skill content becomes part of Claude's instructions
+
+### Manual Verification
+
+You can verify the skill is active by looking for references to:
+- Design tokens (var(--color-primary-600))
+- Component.module.css patterns
+- TypeScript interface requirements
+- DRY/SRP principles
+
+## Example Interactions
+
+### ✅ Skill Auto-Activates
+
+```
+You: "Create a new OrderCard component"
+Claude: *Skill activates automatically*
+Claude: "I'll create OrderCard following the established patterns.
+        Using Card foundational component, design tokens only..."
+```
+
+### ✅ Skill Enforces Patterns
+
+```
+You: "Add some inline styles to the button"
+Claude: "I need to follow the nextjs-ecommerce-guidelines skill.
+        Inline styles are not allowed. Let me use Button.module.css
+        with design tokens instead..."
+```
+
+### ✅ Skill Provides Guidance
+
+```
+You: "How should I structure a new Cart feature?"
+Claude: *Skill activates*
+Claude: "Following the features-first architecture pattern:
+        features/cart/
+          api/
+          components/
+          hooks/
+          types/
+        ..."
+```
+
+## Configuration
+
+The skill configuration is in `skill-rules.json`:
+
+```json
+{
+  "nextjs-ecommerce-guidelines": {
+    "type": "guardrail",
+    "enforcement": "block",
+    "priority": "high"
+  }
+}
+```
+
+### Enforcement Levels
+
+- `"block"` - Required, prevents non-compliant code
+- `"suggest"` - Recommended, but can be overridden
+- `"warn"` - Informational only
+
+### Priority Levels
+
+- `"high"` - Always enforced
+- `"medium"` - Usually enforced
+- `"low"` - Contextual enforcement
+
+## Skill Content
+
+The main skill documentation is in:
+`nextjs-ecommerce-guidelines/SKILL.md`
+
+This contains:
+- Component patterns
+- CSS Module structure
+- TypeScript standards
+- Data fetching patterns
+- WooCommerce integration rules
+- Common mistakes to avoid
+
+## Customizing the Skill
+
+### Add New Triggers
+
+Edit `skill-rules.json` to add new keywords or patterns:
+
+```json
+"keywords": [
+  "component",
+  "your-new-keyword"
+]
+```
+
+### Change Enforcement
+
+```json
+"enforcement": "suggest"  // More lenient
+```
+
+### Skip Certain Paths
+
+```json
+"skipConditions": {
+  "paths": [
+    "src/legacy/**"  // Skip legacy code
+  ]
+}
+```
+
+## Benefits
+
+✅ **Consistency**: Every component follows the same patterns
+✅ **No Reminders Needed**: Skill auto-activates when relevant
+✅ **Guardrails**: Prevents common mistakes before they happen
+✅ **Documentation**: Patterns are always accessible
+✅ **Onboarding**: New team members see patterns immediately
+
+## Troubleshooting
+
+### Skill Not Activating
+
+1. Check you're working in `src/` directory
+2. Verify file extensions match triggers (`.tsx`, `.ts`, `.css`)
+3. Use keywords like "component", "create", "style"
+
+### Too Strict
+
+If the skill is too restrictive, you can:
+1. Change `"enforcement": "suggest"` in skill-rules.json
+2. Add skip paths for specific directories
+3. Adjust the priority to "medium" or "low"
+
+### Not Strict Enough
+
+If you want stronger enforcement:
+1. Ensure `"enforcement": "block"`
+2. Add more trigger patterns
+3. Set `"priority": "high"`
+
+## Best Practices
+
+1. **Let it activate naturally** - Don't manually load it
+2. **Trust the guardrails** - They prevent future tech debt
+3. **Reference SKILL.md** - For detailed pattern documentation
+4. **Update triggers** - As your project grows, add new keywords
+5. **Keep it current** - Update SKILL.md with new patterns
+

Subject: [PATCH 3/4] Add FilterSidebar component - Example of skill-enforced
 development
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Demonstrates what happens when user asks: 'Create a filter system for the shop sidebar'

Created Components:
- FilterSidebar.tsx - Fully featured filter component
- FilterSidebar.module.css - Design token-based styling
- FilterSidebar.example.tsx - Usage demonstration
- filters.ts - TypeScript type definitions

Pattern Adherence (Enforced by Skill):
✅ NO inline styles - all via .module.css
✅ Design tokens only - every value from tokens.css
✅ TypeScript with full JSDoc documentation
✅ React.FC pattern with proper interfaces
✅ Accessibility features (ARIA labels, keyboard nav)
✅ Responsive design using design token breakpoints
✅ Clean component structure

Features Implemented:
- Expandable/collapsible filter groups
- Price range slider with inputs
- Checkbox filters with counts
- Active filter display with removal
- Clear all functionality
- Keyboard navigation support
- Mobile responsive design
- Beautiful spacing and typography using tokens

This is exactly what the skill produces automatically.

From 646798980b08be25669653d15eb9e1a5ec8a912b Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Fri, 7 Nov 2025 09:56:41 +0000
Subject: [PATCH 4/4] Add comprehensive skills planning documentation

Created three key documents for skill management:

1. SKILLS_ROADMAP.md (17 Planned Skills):
   Essential: API routes, error handling, notifications
   High: Cart/checkout, auth, form validation
   Medium: Testing, middleware, email, data fetching
   Low: Performance, security, SEO, i18n, analytics

2. HOW_TO_ADD_SKILLS.md:
   Complete guide for implementing skills
   Two methods: Ask Claude vs DIY
   Configuration options and examples

3. Updated README.md with documentation links

Allows incremental skill implementation as needed.

+# How to Add a New Skill
+
+Quick guide for implementing skills from the roadmap when you need them.
+
+## Method 1: Ask Claude (Recommended) 🤖
+
+Simply ask and Claude will create everything:
+
+```
+You: "Let's add the API routes skill now"
+
+Claude: *Creates:*
+  ✅ .claude/skills/nextjs-api-routes/SKILL.md
+  ✅ Updates skill-rules.json with triggers
+  ✅ Tests auto-activation
+```
+
+Claude knows:
+- The skill structure
+- Proper trigger patterns
+- What should be enforced
+- How to integrate with existing skills
+
+---
+
+## Method 2: DIY (Advanced) 🛠️
+
+### Step 1: Create Skill Directory
+
+```bash
+mkdir -p .claude/skills/your-skill-name
+cd .claude/skills/your-skill-name
+```
+
+### Step 2: Create SKILL.md
+
+```markdown
+---
+name: your-skill-name
+version: 1.0.0
+description: Brief description of what this skill enforces
+type: guardrail
+enforcement: block
+---
+
+# Your Skill Name
+
+**PURPOSE**: What this skill enforces and why
+
+## Core Principles
+
+1. Principle 1
+2. Principle 2
+
+## Patterns
+
+### Pattern Name
+
+Description of the pattern
+
+✅ **REQUIRED**:
+```code
+// Good example
+```
+
+❌ **FORBIDDEN**:
+```code
+// Bad example
+```
+
+## Common Mistakes
+
+1. Mistake 1
+2. Mistake 2
+
+## Examples
+
+[Full working examples]
+
+---
+
+**Remember**: Key takeaway message
+```
+
+### Step 3: Update skill-rules.json
+
+Add your skill to `.claude/skills/skill-rules.json`:
+
+```json
+{
+  "your-skill-name": {
+    "type": "guardrail",
+    "enforcement": "block",
+    "priority": "high",
+    "description": "Brief description",
+    "promptTriggers": {
+      "keywords": [
+        "keyword1",
+        "keyword2",
+        "keyword3"
+      ],
+      "intentPatterns": [
+        "(create|add).*?(thing)",
+        "how.*?(pattern)"
+      ]
+    },
+    "fileTriggers": {
+      "pathPatterns": [
+        "src/specific/path/**/*.ts",
+        "**/*.pattern.ts"
+      ],
+      "contentPatterns": [
+        "import.*from.*library",
+        "specific pattern"
+      ]
+    },
+    "blockMessage": "⚠️ This requires skill. Auto-loaded.",
+    "skipConditions": {
+      "paths": [
+        "node_modules/**",
+        ".next/**"
+      ]
+    }
+  }
+}
+```
+
+### Step 4: Test Activation
+
+Create a test file that should trigger the skill:
+
+```bash
+# Example: Testing API route skill
+mkdir -p src/app/api/test
+touch src/app/api/test/route.ts
+```
+
+Then ask Claude to create something that should trigger it:
+
+```
+You: "Create a GET route in src/app/api/test/route.ts"
+```
+
+Claude should mention the skill activated.
+

+
+## Skill Configuration Options
+
+### Enforcement Levels
+
+```json
+"enforcement": "block"    // Required (strictest)
+"enforcement": "suggest"  // Recommended (medium)
+"enforcement": "warn"     // Informational (lenient)
+```
+
+### Priority Levels
+
+```json
+"priority": "high"    // Always enforced
+"priority": "medium"  // Usually enforced
+"priority": "low"     // Contextual
+```
+
+### Trigger Types
+
+#### Keywords
+Simple word matching:
+```json
+"keywords": ["component", "API", "route"]
+```
+
+Activates when you say:
+- "Create a new component"
+- "Add an API route"
+
+#### Intent Patterns
+Regex for user intent:
+```json
+"intentPatterns": [
+  "(create|add|build).*?(component|feature)",
+  "how.*?(style|organize)"
+]
+```
+
+Matches:
+- "Create a new feature"
+- "How should I style this?"
+
+#### File Path Patterns
+Glob patterns for file paths:
+```json
+"pathPatterns": [
+  "src/app/api/**/*.ts",
+  "src/components/**/*.tsx"
+]
+```
+
+Activates when editing these files.
+
+#### Content Patterns
+Regex for file contents:
+```json
+"contentPatterns": [
+  "import.*from.*'next'",
+  "export async function GET"
+]
+```
+
+Activates when file contains these patterns.
+
+---
+
+## Skill Structure Best Practices
+
+### Keep SKILL.md Under 500 Lines
+
+If longer, split into resources:
+
+```
+skills/
+  your-skill-name/
+    SKILL.md           # Main guide (<500 lines)
+    resources/
+      advanced.md      # Deep dive topics
+      examples.md      # Full examples
+      patterns.md      # Pattern library
+```
+
+### Use Progressive Disclosure
+
+**Main SKILL.md** should have:
+- Quick reference
+- Core principles
+- Common patterns
+- Links to resources for details
+
+**Resources/** should have:
+- Detailed explanations
+- Edge cases
+- Advanced patterns
+- Complex examples
+
+### Clear Examples
+
+Always show both:
+
+```typescript
+// ✅ CORRECT - Do this
+const good = usePattern();
+
+// ❌ WRONG - Don't do this
+const bad = antiPattern();
+```
+
+---
+
+## Testing Your Skill
+
+### Test Checklist
+
+✅ **Activation Tests**
+- [ ] Activates on keywords
+- [ ] Activates on file paths
+- [ ] Activates on content patterns
+- [ ] Doesn't activate when it shouldn't
+
+✅ **Enforcement Tests**
+- [ ] Blocks non-compliant patterns (if block mode)
+- [ ] Suggests alternatives
+- [ ] Provides clear error messages
+
+✅ **Documentation Tests**
+- [ ] Examples are accurate
+- [ ] Patterns are clear
+- [ ] Links work
+- [ ] No typos
+
+### Test Conversation
+
+```
+You: "Create a [thing the skill should handle]"
+
+Expected:
+- Skill activates
+- Claude mentions it
+- Claude follows the patterns
+- Output matches skill rules
+```
+
+---
+
+## Skill Maintenance
+
+### When to Update
+
+Update your skill when:
+- You discover better patterns
+- You find common mistakes
+- You add new features
+- Team agrees on new standards
+
+### Version Control
+
+Update the version in SKILL.md frontmatter:
+
+```markdown
+---
+version: 1.1.0  # Increment when updating
+---
+```
+
+Keep a changelog in the skill:
+
+```markdown
+## Changelog
+
+### v1.1.0 (2025-11-15)
+- Added pattern for X
+- Updated Y examples
+- Fixed Z issue
+```
+
+---
+
+## Common Issues
+
+### Skill Not Activating
+
+**Check:**
+1. Is the file path in `pathPatterns`?
+2. Are keywords correct?
+3. Is skill-rules.json valid JSON?
+4. Restart Claude Code session
+
+### Skill Too Strict
+
+**Solutions:**
+1. Change `"enforcement": "suggest"`
+2. Add more skip conditions
+3. Make patterns more specific
+
+### Skill Conflicts
+
+If two skills conflict:
+1. Use priority levels
+2. Make triggers more specific
+3. Document interaction in both skills
+
+---
+
+## Example: Adding the Notification Skill
+
+Let's walk through adding `notification-system` skill:
+
+### 1. Ask Claude
+
+```
+You: "I need to add success messages when users add items to cart.
+     Let's implement the notification-system skill from the roadmap."
+
+Claude: "I'll create the notification-system skill with:
+         - Toast component patterns
+         - useToast hook pattern
+         - Design token styling
+         - Accessibility standards
+
+         Creating SKILL.md and updating skill-rules.json..."
+```
+
+### 2. Claude Creates Files
+
+```
+.claude/skills/
+  notification-system/
+    SKILL.md          # Toast patterns, accessibility rules
+  skill-rules.json    # Updated with notification triggers
+```
+
+### 3. Test It
+
+```
+You: "Add a success message when product is added to cart"
+
+Claude: *notification-system skill activates*
+        "I'll use the Toast component pattern from the skill:
+
+         const { showSuccess } = useToast();
+         showSuccess('Product added to cart');
+
+         This follows the notification-system skill patterns..."
+```
+
+### 4. It Works!
+
+Now whenever you:
+- Say "toast", "notification", "alert"
+- Work on notification components
+- Add user feedback
+
+The skill automatically enforces:
+- Proper toast structure
+- Design tokens for styling
+- Accessibility (ARIA live regions)
+- Consistent messaging patterns
+
+---
+
+## Quick Reference
+
+| Action | Command |
+|--------|---------|
+| Add skill via Claude | "Let's add the [skill-name] skill" |
+| Create skill manually | `mkdir .claude/skills/skill-name` |
+| Edit skill | Edit `SKILL.md` and `skill-rules.json` |
+| Test activation | Create trigger file or use keywords |
+| Check if active | Claude will mention it in response |
+| Disable temporarily | Remove from `skill-rules.json` |
+| Update skill | Edit SKILL.md, increment version |
+
+---
+
+## Resources
+
+- **Roadmap**: See `SKILLS_ROADMAP.md` for all planned skills
+- **Examples**: Check existing `nextjs-ecommerce-guidelines` skill
+- **Showcase Repo**: `/claude-code-infrastructure-showcase/.claude/skills/`
+
+---
+
+**Pro Tip**: Start simple! Add skills one at a time as you need them. It's better to have 3 well-used skills than 15 ignored ones.

+
+## How to Add a Skill
+
+When you're ready to implement a skill:
+
+### **Option 1: Ask Me**
+```
+You: "Let's add the API routes skill now"
+Me: *Creates complete skill with SKILL.md and skill-rules.json*
+```
+
+### **Option 2: DIY**
+```bash
+# Create skill directory
+mkdir -p .claude/skills/skill-name
+
+# Create SKILL.md with patterns
+# Create skill-rules.json with triggers
+# Test auto-activation
+```
+
+---
+
+## Skill Interaction Matrix
+
+Some skills work together:
+
+| Skill | Works With | Enhances |
+|-------|-----------|----------|
+| `nextjs-api-routes` | `error-handling-patterns` | Better API error handling |
+| `cart-checkout-patterns` | `notification-system` | Cart feedback messages |
+| `form-validation` | `notification-system` | Validation feedback |
+| `authentication-patterns` | `middleware-patterns` | Protected routes |
+| `error-handling-patterns` | `notification-system` | User-friendly errors |
+| `testing-guidelines` | ALL | Validates patterns work |
+
+---
+
+## Current Template Status
+
+**Completed:**
+- ✅ Design token system
+- ✅ Foundational components (6)
+- ✅ WooCommerce integration layer
+- ✅ Stripe integration layer
+- ✅ Example products feature
+- ✅ FilterSidebar component
+- ✅ `nextjs-ecommerce-guidelines` skill
+
+**Next Priorities:**
+1. Build first API route → Add `nextjs-api-routes` skill
+2. Add success messages → Add `notification-system` skill
+3. Build cart → Add `cart-checkout-patterns` skill
+
+---
+
+## Notes
+
+- Skills can be added **incrementally** - no need to implement all upfront
+- Skills **auto-activate** based on what you're working on
+- Skills can **reference each other** for complementary patterns
+- **Keep skills focused** - better to have 10 focused skills than 3 giant ones
+- Skills **evolve** - update them as you learn better patterns
