+
+# Atomic Design Frontend System with Tailwind CSS
+
+A comprehensive guide for building modern, responsive frontend applications
+using atomic design principles and Tailwind CSS.
+
+## Core Principles
+
+### 1. Atomic Design Hierarchy
+
+Atomic Design breaks UI into five distinct levels:
+
+#### **Atoms**
+
+Smallest, indivisible UI elements that cannot be broken down without losing
+functionality.
+
+- Buttons, input fields, labels, icons, text styles
+- Color variables, spacing units, typography scales
+- Simple, pure, reusable building blocks
+
+```jsx
+// Example: Button Atom
+<button className="rounded-lg bg-blue-600 px-4 py-2 text-white transition-colors hover:bg-blue-700">
+  Click me
+</button>
+```
+
+#### **Molecules**
+
+Groups of atoms bonded together, forming simple functional units.
+
+- Search bars (input + button + icon)
+- Form fields (label + input + error message)
+- Card headers (avatar + title + subtitle)
+- Navigation items with icons and labels
+
+```jsx
+// Example: Search Molecule
+<div className="flex items-center gap-2 rounded-lg border border-gray-300 px-4 py-2">
+  <SearchIcon className="h-5 w-5 text-gray-500" />
+  <input type="text" placeholder="Search..." className="flex-1 outline-none" />
+</div>
+```
+
+#### **Organisms**
+
+Complex functional units made of groups of molecules and/or atoms.
+
+- Header/Navigation bars
+- Form sections (multiple form molecules)
+- Card layouts with multiple sections
+- Modals with title, content, and actions
+- Data tables with headers, rows, and pagination
+
+```jsx
+// Example: Product Card Organism
+<div className="overflow-hidden rounded-lg border border-gray-200 shadow-sm transition-shadow hover:shadow-md">
+  <img src="image.jpg" className="h-48 w-full object-cover" />
+  <div className="p-4">
+    <h3 className="text-lg font-semibold">Product Name</h3>
+    <p className="mt-1 text-sm text-gray-600">Description</p>
+    <div className="mt-4 flex items-center justify-between">
+      <span className="font-bold text-blue-600">$99</span>
+      <button className="rounded bg-blue-600 px-3 py-1 text-white">Add</button>
+    </div>
+  </div>
+</div>
+```
+
+#### **Templates**
+
+Page-level wireframes showing layout and component placement without final
+content.
+
+- Single-column layouts
+- Two-column layouts (sidebar + main)
+- Grid-based layouts
+- Hero + content sections
+
+#### **Pages**
+
+Specific instances of templates populated with real content and data.
+
+- Homepage with actual products
+- User profile with real user data
+- Dashboard with live metrics
+
+---
+
+## Design System Variables (Reusable Values)
+
+### Color Palette
+
+```css
+/* Define in Tailwind config or use CSS variables */
+Primary: #2563eb (blue-600)
+Secondary: #7c3aed (violet-600)
+Success: #16a34a (green-600)
+Warning: #ea580c (orange-600)
+Danger: #dc2626 (red-600)
+Neutral: #6b7280 (gray-500)
+```
+
+### Typography Scale
+
+```css
+H1: 32px (2rem) - font-bold
+H2: 24px (1.5rem) - font-bold
+H3: 20px (1.25rem) - font-semibold
+Body: 16px (1rem) - font-normal
+Small: 14px (0.875rem) - font-normal
+Tiny: 12px (0.75rem) - font-normal
+```
+
+### Spacing Scale
+
+```css
+xs: 4px (0.25rem)
+sm: 8px (0.5rem)
+md: 16px (1rem)
+lg: 24px (1.5rem)
+xl: 32px (2rem)
+2xl: 48px (3rem)
+```
+
+### Border Radius
+
+```css
+Subtle: 4px (rounded-sm)
+Standard: 8px (rounded-lg)
+Large: 12px (rounded-xl)
+Full: 9999px (rounded-full)
+```
+
+### Box Shadows
+
+```css
+Subtle: 0 1px 2px rgba(0,0,0,0.05)
+Soft: 0 4px 6px rgba(0,0,0,0.07)
+Medium: 0 10px 15px rgba(0,0,0,0.10)
+Strong: 0 20px 25px rgba(0,0,0,0.15)
+```
+
+---
+
+## Responsive Design Strategy
+
+### Breakpoints (Tailwind Default)
+
+```
+Mobile:   < 640px    (sm)
+Tablet:   640px      (md, lg)
+Desktop:  1024px+    (xl, 2xl)
+```
+
+### Mobile-First Approach
+
+1. **Start with mobile styles** (default, no prefix)
+2. **Layer tablet styles** (md: prefix)
+3. **Layer desktop styles** (lg:, xl: prefix)
+
+### Example: Responsive Layout
+
+```jsx
+// Mobile: 1 column, Tablet: 2 columns, Desktop: 3 columns
+<div className="grid grid-cols-1 gap-4 md:grid-cols-2 lg:grid-cols-3">
+  {items.map((item) => (
+    <Card key={item.id} {...item} />
+  ))}
+</div>
+```
+
+### Common Responsive Patterns
+
+**Responsive Typography**
+
+```jsx
+<h1 className="text-2xl font-bold md:text-3xl lg:text-4xl">
+  Responsive Heading
+</h1>
+```
+
+**Responsive Padding/Margins**
+
+```jsx
+<div className="p-4 md:p-6 lg:p-8">Content with responsive spacing</div>
+```
+
+**Responsive Grid**
+
+```jsx
+<div className="grid grid-cols-2 gap-4 md:grid-cols-3 md:gap-6 lg:grid-cols-4">
+  {/* Grid items */}
+</div>
+```
+
+**Responsive Flexbox**
+
+```jsx
+<div className="flex flex-col gap-4 md:flex-row">
+  <aside className="w-full md:w-64">Sidebar</aside>
+  <main className="flex-1">Main content</main>
+</div>
+```
+
+**Responsive Images**
+
+```jsx
+<img
+  src="image.jpg"
+  className="h-auto w-full object-cover"
+  alt="Responsive image"
+/>
+```
+
+---
+
+## Modern Design Patterns
+
+### 1. Consistency & Visual Hierarchy
+
+- **Use consistent spacing**: Apply spacing scale uniformly
+- **Establish clear hierarchy**: Size, weight, color for emphasis
+- **Group related content**: Use whitespace to separate sections
+- **Align elements**: Use grids for crisp layouts
+
+```jsx
+<section className="space-y-6">
+  <div>
+    <h2 className="mb-2 text-2xl font-bold">Section Title</h2>
+    <p className="text-gray-600">Description text</p>
+  </div>
+  <div className="space-y-4">{/* Related items with consistent spacing */}</div>
+</section>
+```
+
+### 2. Interactive Feedback
+
+- **Hover states**: Subtle color/shadow changes
+- **Active states**: Indicate current selection
+- **Focus states**: Keyboard navigation support
+- **Loading states**: Spinners or skeleton screens
+- **Transitions**: Smooth animations (200-300ms)
+
+```jsx
+<button className="rounded-lg bg-blue-600 px-4 py-2 text-white transition-all duration-200 hover:bg-blue-700 focus:ring-2 focus:ring-blue-500 focus:outline-none active:scale-95 disabled:cursor-not-allowed disabled:opacity-50">
+  Actionable Button
+</button>
+```
+
+### 3. Depth & Layering
+
+- **Subtle shadows**: Create depth without heaviness
+- **Elevation levels**: Consistent shadow progression
+- **Overlays**: Semi-transparent backgrounds for modals
+- **Z-index strategy**: Clear layering hierarchy
+
+```jsx
+<div className="rounded-lg border border-gray-200 shadow-sm transition-shadow duration-300 hover:shadow-md">
+  Card content
+</div>
+```
+
+### 4. Color Usage
+
+- **Primary action**: Most frequent call-to-action
+- **Secondary action**: Alternative actions
+- **Semantic colors**: Status indicators (success, warning, danger)
+- **Contrast**: Ensure WCAG AA compliance (4.5:1 ratio)
+- **Limited palette**: 3-5 colors maximum in most designs
+
+### 5. Whitespace & Breathing Room
+
+- Don't crowd elements
+- Use consistent gap values (gap-4, gap-6, gap-8)
+- Separate sections with vertical rhythm
+- Generous padding in cards and containers
+
+```jsx
+<div className="mx-auto max-w-4xl px-4 py-8 md:px-6 md:py-12">
+  <div className="space-y-8">{/* Sections with good breathing room */}</div>
+</div>
+```
+
+---
+
+## Tailwind CSS Best Practices
+
+### 1. Use Utility Classes Effectively
+
+```jsx
+// Good: Semantic, reusable, organized
+<button className="
+  px-4 py-2
+  bg-blue-600 text-white
+  rounded-lg
+  hover:bg-blue-700
+  transition-colors
+  disabled:opacity-50
+">
+  Submit
+</button>
+
+// Avoid: Too many utilities, hard to read
+<button className="px-4 py-2 bg-blue-600 text-white rounded-lg hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2 active:scale-95 disabled:opacity-50 disabled:cursor-not-allowed transition-all duration-200">
+```
+
+### 2. Extract Reusable Components
+
+```jsx
+// Create a Button component to avoid repetition
+const Button = ({ children, variant = "primary", ...props }) => {
+  const baseStyles = "px-4 py-2 rounded-lg font-medium transition-colors";
+  const variants = {
+    primary: "bg-blue-600 text-white hover:bg-blue-700",
+    secondary: "bg-gray-200 text-gray-900 hover:bg-gray-300",
+    danger: "bg-red-600 text-white hover:bg-red-700",
+  };
+
+  return (
+    <button className={`${baseStyles} ${variants[variant]}`} {...props}>
+      {children}
+    </button>
+  );
+};
+```
+
+### 3. Organize Utility Classes
+
+```jsx
+// Organize by category: layout → sizing → colors → effects → responsive
+<div className="/* Layout */ /* Sizing */ /* Spacing */ /* Colors & text */ /* Borders & shadows */ /* Effects */ /* Responsive */ my-8 flex w-full max-w-2xl flex-col gap-4 rounded-lg border border-gray-200 bg-white p-6 text-gray-900 shadow-sm transition-shadow hover:shadow-md md:flex-row lg:gap-6"></div>
+```
+
+### 4. Use Tailwind Config for Consistency
+
+```js
+// tailwind.config.js
+module.exports = {
+  theme: {
+    extend: {
+      colors: {
+        primary: "#2563eb",
+        secondary: "#7c3aed",
+      },
+      spacing: {
+        gutter: "1rem",
+      },
+    },
+  },
+};
+```
+
+---
+
+## Component Construction Template
+
+Use this template when building atomic components:
+
+```jsx
+/**
+ * {Component Name}
+ *
+ * Atoms/Molecules/Organisms level component
+ * Purpose: [Brief description]
+ *
+ * Props:
+ *   - prop1: type - description
+ *   - prop2: type - description
+ */
+
+export const ComponentName = ({ prop1, prop2, className = "" }) => {
+  return (
+    <div
+      className={`/* Base styles */ /* Responsive */ /* Custom className */ flex flex-col gap-4 rounded-lg border border-gray-200 bg-white p-6 md:flex-row lg:p-8 ${className} `}
+    >
+      {/* Component content */}
+    </div>
+  );
+};
+```
+
+---
+
+## Layout Patterns
+
+### Container + Padding
+
+```jsx
+<div className="mx-auto max-w-6xl px-4 md:px-6 lg:px-8">
+  {/* Content constrained to max width with responsive padding */}
+</div>
+```
+
+### Two-Column Sidebar Layout
+
+```jsx
+<div className="flex flex-col gap-6 lg:flex-row">
+  <aside className="w-full flex-shrink-0 lg:w-64">
+    {/* Sidebar: full width on mobile, fixed on desktop */}
+  </aside>
+  <main className="min-w-0 flex-1">
+    {/* Main content: takes remaining space */}
+  </main>
+</div>
+```
+
+### Responsive Grid
+
+```jsx
+<div className="grid grid-cols-1 gap-6 md:grid-cols-2 lg:grid-cols-3">
+  {/* Items automatically stack on mobile, 2 columns on tablet, 3 on desktop */}
+</div>
+```
+
+### Hero Section
+
+```jsx
+<section className="relative overflow-hidden bg-gradient-to-r from-blue-600 to-violet-600 py-12 text-white md:py-20 lg:py-32">
+  <div className="relative z-10 mx-auto max-w-6xl px-4 md:px-6">
+    <h1 className="mb-4 text-4xl font-bold md:text-5xl lg:text-6xl">
+      Hero Title
+    </h1>
+    <p className="mb-8 max-w-2xl text-lg opacity-90 md:text-xl">
+      Hero subtitle or description
+    </p>
+    <button className="rounded-lg bg-white px-8 py-3 font-semibold text-blue-600 transition-colors hover:bg-gray-100">
+      Call to Action
+    </button>
+  </div>
+</section>
+```
+
+---
+
+## Accessibility & Best Practices
+
+1. **Semantic HTML**: Use `<button>`, `<a>`, `<form>`, etc. appropriately
+2. **Color contrast**: Ensure 4.5:1 for text, 3:1 for UI components
+3. **Focus states**: Always visible keyboard navigation (`focus:ring-2`)
+4. **ARIA labels**: Add when needed (`aria-label`, `aria-describedby`)
+5. **Responsive text**: Use relative sizing, not fixed pixels
+6. **Touch targets**: Minimum 44x44px for interactive elements
+
+```jsx
+<button
+  className="min-h-[44px] px-4 py-3 focus:ring-2 focus:ring-offset-2 focus:outline-none"
+  aria-label="Close modal"
+>
+  ✕
+</button>
+```
+
+---
+
+## Performance Considerations
+
+1. **Limit custom CSS**: Rely on Tailwind utilities
+2. **Tree-shake unused styles**: Configure Tailwind content paths
+3. **Optimize images**: Use responsive images, WebP format
+4. **Lazy load**: Defer non-critical components
+5. **Minimize bundle**: Use PurgeCSS in production
+
+---
+
+## Quick Reference Checklist
+
+When building a component, ensure:
+
+- [ ] Follows atomic design hierarchy (Atom/Molecule/Organism)
+- [ ] Uses design system variables (colors, spacing, typography)
+- [ ] Responsive across mobile, tablet, desktop
+- [ ] Consistent hover/active/focus states
+- [ ] Proper whitespace and visual hierarchy
+- [ ] Semantic HTML structure
+- [ ] Accessible (contrast, focus, labels)

+---
+
+# Prompt Optimizer
+
+A beginner-friendly skill for improving AI/LLM prompts to get better results.
+
+## What This Skill Does
+
+This skill helps you rewrite prompts to work better with AI models like Claude.
+Instead of just giving you a rewritten prompt, it shows you specific improvement
+suggestions that you can choose to apply or skip.
+
+## Key Improvements
+
+When optimizing a prompt, focus on three main areas:
+
+### 1. **Specificity** — Making the Request Clear
+
+Good prompts are specific about what you want. Vague prompts get vague results.
+
+**Example improvements:**
+
+- Add details about format: "Give me a bullet list of 5 items" instead of "tell
+  me about X"
+- Be clear about length: "Write 200 words" instead of "Write something short"
+- Define who the audience is: "Explain this for a 10-year-old" or "Use technical
+  language"
+
+### 2. **Context** — Giving the AI Background Information
+
+More context helps the AI make better decisions.
+
+**Example improvements:**
+
+- Explain the goal: "I'm writing a resume, so focus on professional language"
+- Share constraints: "We only have $500 budget" or "It needs to work on mobile"
+- Provide background: "I already know Python but not JavaScript"
+
+### 3. **Constraints** — Setting Boundaries
+
+Constraints prevent unwanted outputs.
+
+**Example improvements:**
+
+- Set length limits: "Keep it under 100 words"
+- Specify format: "Use JSON format" or "Write as a numbered list"
+- Define tone: "Be casual and friendly, not formal"
+- Say what NOT to include: "Don't use technical jargon"
+
+## How to Use This Skill
+
+1. **Share your prompt** — Give me the original prompt you want to improve
+2. **Review suggestions** — I'll show you specific improvements in each area
+3. **Choose what you like** — Pick which suggestions to apply
+4. **Get the final version** — I'll rewrite your prompt with your chosen
+   improvements
+
+## Interactive Selection Process
+
+When you use this skill, you'll see:
+
+- **Original prompt** — Your starting point
+- **Improvement suggestions** — Specific changes grouped by category
+  (Specificity, Context, Constraints)
+- **Preview examples** — What each change would look like with the improvement
+  applied
+- **Your choices** — You pick which suggestions help most (you can apply all,
+  some, or none)
+
+Then you get a rewritten prompt combining all your choices.
+
+### Example Interaction
+
+**Original:** "Write me a blog post"
+
+**Suggestions I might offer:**
+
+- **Specificity**: Add a topic (e.g., "about sustainable living")
+- **Context**: Explain your goal (e.g., "to build authority on my website")
+- **Constraints**: Set a word count (e.g., "800-1000 words")
+
+**Your choice:** "I want all three — add topic, goal, and word count"
+
+**Final rewritten prompt:** "Write an 800-1000 word blog post about sustainable
+living for my website. The goal is to establish my authority on eco-friendly
+practices. Target an audience of people interested in reducing their carbon
+footprint. Include 3-4 practical tips they can implement immediately, and end
+with a call-to-action encouraging them to sign up for my newsletter."
+
+## Tips for Best Results
+
+- **Start simple** — Even small improvements help
+- **Focus on your goal** — What outcome do you want?
+- **Add one constraint at a time** — Too many rules can be confusing
+- **Test and iterate** — Try the new prompt and see if results improve
+
+## What Makes a Good Prompt
+
+A prompt becomes "good" when:
+
+- The AI understands exactly what you want ✓
+- You've given enough context to explain why ✓
+- You've set boundaries to prevent bad outputs ✓
+- Someone else could read it and understand your intent ✓

+
+# UI/UX Testing Skill
+
+This skill helps developers create automated visual regression tests and
+comprehensive UI/UX testing strategies for web applications.
+
+## Overview
+
+When a developer asks you to test a UI or create visual regression tests, this
+skill guides you through:
+
+1. **Analyzing the target URL** - Inspect the web page structure and components
+2. **Generating test strategies** - Create both automated and manual testing
+   approaches
+3. **Writing test code** - Generate Playwright/Cypress test scripts or Selenium
+   code
+4. **Creating test checklists** - Manual testing steps for visual regression and
+   UX flows
+5. **Generating reports** - Detailed findings, issues, and recommendations in
+   markdown/HTML
+
+## When to Trigger
+
+Trigger this skill when the user:
+
+- Provides a URL and asks to "test this UI"
+- Requests "visual regression testing" for a web page
+- Wants to "check accessibility" or test a component
+- Asks to "create automated tests" for a UI
+- Wants a "testing strategy" or "test plan" for a web application
+- Mentions QA, testing, or validation of UI components
+
+## Workflow
+
+### Step 1: Inspect the Target URL
+
+Use Claude in Chrome to:
+
+- Navigate to the provided URL
+- Take screenshots of different viewport sizes (desktop, tablet, mobile)
+- Inspect the DOM structure using `read_page` tool
+- Identify key components, interactive elements, and critical flows
+- Note responsive behavior and CSS properties
+
+### Step 2: Create a Test Strategy
+
+Based on your inspection, identify:
+
+- **Visual elements** to regression test (buttons, forms, headers, layouts)
+- **Interactive flows** to test (hover states, click handlers, form submission)
+- **Responsive breakpoints** to validate (mobile, tablet, desktop)
+- **Accessibility concerns** (ARIA labels, color contrast, keyboard navigation)
+- **Critical user paths** to validate (common workflows)
+
+### Step 3: Generate Test Code
+
+**For Automated Testing (Choose one or more):**
+
+#### Playwright (Recommended)
+
+```javascript
+// Example structure
+import { expect, test } from "@playwright/test";
+
+test("visual regression - homepage", async ({ page }) => {
+  await page.goto("https://example.com");
+
+  // Capture baseline screenshot
+  await expect(page).toHaveScreenshot("homepage.png");
+
+  // Test interactive elements
+  await page.hover("button.primary");
+  await expect(page).toHaveScreenshot("button-hover.png");
+});
+
+test("responsive layout - mobile", async ({ page }) => {
+  await page.setViewportSize({ width: 375, height: 812 });
+  await page.goto("https://example.com");
+  await expect(page).toHaveScreenshot("mobile-layout.png");
+});
+```
+
+#### Cypress
+
+```javascript
+describe("Visual Regression Tests", () => {
+  beforeEach(() => {
+    cy.visit("https://example.com");
+  });
+
+  it("captures baseline screenshot", () => {
+    cy.screenshot("homepage");
+    cy.get('[data-testid="header"]').should("be.visible");
+  });
+
+  it("tests button hover state", () => {
+    cy.get("button.primary").trigger("mouseenter");
+    cy.screenshot("button-hover-state");
+  });
+});
+```
+
+#### Selenium
+
+```python
+from selenium import webdriver
+from selenium.webdriver.common.by import By
+from PIL import Image
+
+driver = webdriver.Chrome()
+driver.get('https://example.com')
+
+# Capture screenshot
+driver.save_screenshot('homepage.png')
+
+# Test responsive
+driver.set_window_size(375, 812)
+driver.save_screenshot('mobile-view.png')
+```
+
+### Step 4: Create Manual Testing Checklist
+
+Generate a checklist including:
+
+- [ ] **Visual Consistency**
+  - [ ] All elements render correctly at 1920x1080
+  - [ ] All elements render correctly at 1366x768
+  - [ ] All elements render correctly at 768x1024 (tablet)

+
+## Output Options
+
+Based on what the developer needs, generate:
+
+1. **Test Code Only** - Playwright/Cypress/Selenium scripts ready to integrate
+2. **Testing Strategy** - Comprehensive checklist and manual test plan
+3. **Full Report** - Screenshots, findings, issues, and automated test code
+4. **All of the above** - Complete testing package
+
+## Best Practices
+
+- **Multiple viewports:** Always test at least mobile (375px), tablet (768px),
+  and desktop (1920px)
+- **Visual baselines:** Save baseline screenshots before making changes
+- **Critical paths:** Prioritize testing main user workflows first
+- **Accessibility first:** Include WCAG AA compliance checks
+- **Clear assertions:** Make test assertions explicit and meaningful
+- **Maintainability:** Use data attributes (data-testid) for reliable element
+  selection
+
+## Example: Complete Testing Session
+
+1. Developer provides URL: "https://myapp.com/dashboard"
+2. You inspect the page (screenshots, DOM, responsive behavior)
+3. You identify:
+   - Dashboard header with navigation
+   - Data table with sorting/filtering
+   - Form for creating items
+   - Mobile menu collapse
+4. You generate:
+   - Playwright tests for visual regression
+   - Manual testing checklist
+   - HTML report with findings
+5. Developer receives complete testing artifact ready to use
+
+## Tips for Success
+
+- Take screenshots at each viewport to catch responsive issues
+- Test interactive states (hover, focus, active, disabled)
+- Verify critical user journeys end-to-end
+- Include accessibility testing automatically
+- Provide both automated (code) and manual (checklist) approaches
+- Make reports actionable with clear severity levels and recommendations

+# Website Creation Automation Skill
+
+An intelligent, end-to-end automation workflow for creating complete, tested
+websites from simple prompts.
+
+## What This Skill Does
+
+This skill orchestrates a complete website creation pipeline:
+
+1. **Prompt Optimization** — Takes your website description and optimizes it
+   into a detailed, structured prompt
+2. **Website Design** — Uses the optimized prompt to design and build a modern,
+   responsive website
+3. **Automated Testing** — Tests the generated website for visual, interactive,
+   and responsive issues
+4. **Auto-Fix** — Detects and fixes any issues found during testing
+
+The entire workflow is automated, so you just provide a simple description of
+what you want, and the skill handles the rest.
+
+## Core Workflow
+
+### Step 1: Optimize Your Website Prompt
+
+Your initial description (e.g., "Create a portfolio website for a freelance
+designer") is passed to the **prompt-optimizer** skill, which:
+
+- Adds specific details about layout, features, and target audience
+- Clarifies design preferences and functionality requirements
+- Structures the request to guide high-quality website generation
+- Returns a detailed, optimized prompt ready for design
+
+**Example transformation:**
+
+```
+Input: "Create a portfolio website for a freelance designer"
+↓
+Output: "Create a modern portfolio website for a freelance graphic designer.
+Include: hero section with featured work, project showcase grid (6-8 projects),
+about section, services list, client testimonials, contact form, and footer.
+Target audience: potential clients and collaborators. Design should be minimalist
+with emphasis on visual work. Mobile-responsive. Use modern sans-serif typography
+and white space. Include smooth scroll animations."
+```
+
+### Step 2: Design the Website
+
+The **frontend-atomic-design** skill uses the optimized prompt to:
+
+- Break down the website into atomic components (atoms, molecules, organisms)
+- Create a responsive layout that works on desktop, tablet, and mobile
+- Apply modern design patterns using Tailwind CSS
+- Build interactive elements and proper semantic HTML
+- Generate a complete, production-ready HTML file (or React component)
+
+**Outputs:**
+
+- Full HTML file with embedded CSS and JavaScript
+- All assets (icons, fonts) are self-contained
+- Responsive design with mobile-first approach
+- Accessible markup with semantic HTML5
+
+### Step 3: Test the Website
+
+The **ui-ux-testing** skill performs comprehensive testing:
+
+- Visual regression testing (captures baseline screenshots)
+- Responsive layout validation (mobile, tablet, desktop)
+- Interactive element testing (buttons, forms, links)
+- Accessibility checking (color contrast, keyboard navigation)
+- Cross-browser compatibility assessment
+- User flow validation
+
+**Testing output includes:**
+
+- Screenshots from multiple viewport sizes
+- Detailed findings and issues detected
+- Visual regression comparison
+- Recommendations for improvements
+
+### Step 4: Auto-Fix Detected Issues
+
+Any issues detected in testing are automatically fixed:
+
+- **Using Haiku 4.5** — A faster model optimized for targeted fixes
+- **HTML-only fixes** — Modifications to structure, styling, or interactivity
+- **Preserves design intent** — Fixes maintain the original design aesthetic
+- **Re-validates** — Quick verification that fixes resolved the issues
+
+**Common fixes include:**
+
+- Correcting responsive behavior issues
+- Fixing accessibility problems
+- Adjusting spacing, alignment, or colors
+- Improving interactive element behavior
+- Ensuring all content is properly visible
+
+---
+
+## When to Use This Skill
+
+Use this skill whenever you want to:
+
+- **Create a new website** from scratch based on a description
+- **Build a landing page** for a product, service, or event
+- **Design a portfolio site** to showcase your work
+- **Create an e-commerce page** with product displays
+- **Build a dashboard or web app** UI
+- **Generate a multi-page website** (returns first page, can iterate)
+- **Prototype a website concept** quickly
+
+## How to Trigger This Skill
+
+Simply provide:
+
+1. **Website description** — What kind of website you want (e.g., "e-commerce
+   store for handmade jewelry", "SaaS landing page", "restaurant menu website")
+2. **Optional details** — Any specific requirements (colors, features, tone,
+   audience)
+
+The skill handles everything else automatically.
+
+## Example Usage
+
+**User prompt:** "Create a landing page for a sustainable fashion startup called
+EcoStitch. Include a hero section, features of our eco-friendly materials,
+pricing plans, customer testimonials, and a newsletter signup."
+
+**Skill processes:**
+
+1. Optimizes prompt with specific design details and layout structure
+2. Designs a modern, responsive landing page with all requested sections
+3. Tests layout across mobile/tablet/desktop, forms, links, and visual design
+4. Fixes any responsive or interactive issues found
+5. Returns production-ready HTML file
+
+**Final output:** A complete, tested, bug-free website ready to deploy or
+customize further.
+
+---
+
+## Technical Details
+
+### Model Usage
+
+- **Sonnet 4.6** — Used for optimization, design, and testing (high-quality
+  complex tasks)
+- **Haiku 4.5** — Used for bug fixes only (fast, targeted improvements)
+
+### Skill Integration
+
+This skill coordinates three core skills in sequence:
+
+```
+User Prompt
+    ↓
+[prompt-optimizer] → Optimized Prompt
+    ↓
+[frontend-atomic-design] → HTML/React Website
+    ↓
+[ui-ux-testing] → Test Results + Screenshots
+    ↓
+[Bug Fix Loop] → Fixed HTML/React Website
+    ↓
+Final Website (Ready to Use)
+```
+
+### Output Format
+
+The final website is delivered as:
+
+- **HTML file** — Self-contained with CSS and JavaScript embedded
+- **Screenshots** — Before/after testing comparison
+- **Test report** — Issues found and fixes applied
+- **Deployment ready** — Can be hosted on any static hosting service
+
+---
+
+## Limitations & Notes
+
+- **Single-page output** — Generates one complete page (though can be expanded
+  to multi-page)
+- **Static by default** — Returns HTML; can generate React components if needed
+- **Database-free** — Forms are functional but don't store data without backend
+  integration
+- **Rapid iteration** — If you want to modify the result, you can iterate by
+  running the skill again with updated requirements
+
+---
+
+## Tips for Best Results
+
+1. **Be descriptive** — More detail in your initial prompt leads to better
+   results
+2. **Specify audience** — Who is this website for? (target customers, users,
+   etc.)
+3. **Include features** — What should the website do? (e.g., showcase products,
+   collect emails, etc.)
+4. **Mention style** — Any aesthetic preferences? (minimalist, colorful,
+   corporate, playful, etc.)
+5. **Test thoroughly** — Review the testing results to ensure the site meets
+   your needs

-## Overview
-
-Project sử dụng **Atomic Design Pattern** để tổ chức UI components theo 5 cấp
-độ:
-
-1. **Atoms** - Khối xây dựng cơ bản, không thể chia nhỏ hơn
-2. **Molecules** - Nhóm atoms đơn giản hoạt động cùng nhau
-3. **Organisms** - Khu vực UI phức tạp, riêng biệt
-4. **Templates** - Bố cục cấp trang, cấu trúc nội dung
-5. **Pages** - Các phiên bản cụ thể với dữ liệu thật
-

-## 4) TEMPLATES (`components/templates/`)
-
-**Mục đích:** Bố cục cấp trang, cấu trúc nội dung, không có data cụ thể.
-
-Chứa layout và structure của page, nhưng data được truyền từ page component.
-
-### Cấu trúc thư mục
-
-```
-components/templates/
-├── main-layout/
-│   ├── MainLayout.tsx       # Layout chính (header + sidebar + content + footer)
-│   ├── MainLayout.types.ts  # Props types
-│   └── styles.ts            # Responsive grid layout logic
-├── feed-layout/
-│   ├── FeedLayout.tsx       # Layout feed (khám phá quán)
-│   └── FeedLayout.types.ts  # Props types
-├── manager-layout/

-│   └── AuthLayout.types.ts  # Props types
-└── index.ts                 # Barrel export
-```
-
-### Ví dụ Templates
-
-**MainLayout.tsx:**
-
-```tsx
-import Navbar from "@/components/organisms/navigation/Navbar";
-import Footer from "@/layouts/footer";
-import Header from "@/layouts/header";
-
-import type { MainLayoutProps } from "./MainLayout.types";
-
-export default function MainLayout({ children }: MainLayoutProps) {
-  return (
-    <div className="flex min-h-screen flex-col">
-      <Header />
-      <div className="flex flex-1">
-        {/* Sidebar - ẩn trên mobile */}
-        <nav className="hidden w-64 border-r border-[color:var(--color-border)] bg-[color:var(--color-bg-sidebar)] md:block">
-          <Navbar />
-        </nav>
-        {/* Main content */}
-        <main className="flex-1 p-4 md:p-6">{children}</main>
-      </div>
-      <Footer />
-    </div>
-  );
-}
-```
-
----
-
-## 5) PAGES (`app/*/page.tsx`)
-
-**Mục đích:** Các phiên bản cụ thể với dữ liệu thật, logic cấp trang.
-
-Server/client components sử dụng templates, organisms, nhận data từ API/context.
-
-### Ví dụ Pages
-
-**app/(main)/page.tsx:**
-
-```tsx
-"use client";
-
-import FeaturedSection from "@/components/organisms/featured-section/FeaturedSection";
-import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
-import MainLayout from "@/components/templates/main-layout/MainLayout";
-import { useState } from "react";
-
-export default function MainPage() {
-  const [searchQuery, setSearchQuery] = useState("");
-
-  return (
-    <MainLayout>
-      <FeaturedSection />
-      <div className="mt-8">
-        <ProductGrid searchQuery={searchQuery} />
-      </div>
-    </MainLayout>
-  );

-## 7) Migration Guide (Old → New)
-
-### Old Structure → New Structure Mapping
-
-| Old File          | New Location                       | Type     |
-| ----------------- | ---------------------------------- | -------- |
-| `CartProduct.tsx` | `molecules/cards/ProductCard.tsx`  | Molecule |
-| `Navbar.tsx`      | `organisms/navigation/Navbar.tsx`  | Organism |
-| `CartFab.tsx`     | `organisms/cart/CartFab.tsx`       | Organism |
-| `ReviewModal.tsx` | `organisms/modals/ReviewModal.tsx` | Organism |
-
-### Migration Steps
-
-1. Create new directory structure under `components/`
-2. Move existing components to appropriate levels (atoms → molecules →
-   organisms)
-3. Extract shared styles/logic into atoms
-4. Update imports in `app/` pages
-5. Test responsiveness at each breakpoint
-6. Update `COMPONENTS.md` with new structure
-
----
-
-## 8) Best Practices
-
-### Atoms Development
-
-- ✅ Reusable across entire project
-- ✅ No business logic
-- ✅ No context/hooks (useAuth, useCart)
-- ✅ Pure props-based
-- ✅ Full TypeScript typing
-- ❌ No "use client" needed (unless interactive, e.g., Button)
-
-### Molecules Development
-
-- ✅ Combines multiple atoms
-- ✅ Simple state (open/close, hover state)
-- ✅ No complex business logic
-- ✅ Can use useState for UI state
-- ✅ Reusable in multiple contexts
-- ❌ No global state (useAuth, useCart)
-
-### Organisms Development
-
-- ✅ Complex UI sections
-- ✅ Can use contexts (useAuth, useCart, useMenu)
-- ✅ Business logic
-- ✅ Always "use client"
-- ✅ Filter, sort, complex interactions
-- ❌ Not reusable across different page types
-
-### Templates Development
-
-- ✅ Page layout structure
-- ✅ Composition of organisms + layout
-- ✅ No data fetching/business logic
-- ✅ Children prop pattern
-- ✅ Props for customization
-- ❌ No hardcoded data
-
-### Pages Development
-
-- ✅ Specific page implementations
-- ✅ Route-specific logic
-- ✅ Data integration
-- ✅ Context usage at page level
-- ✅ State management orchestration
-- ❌ No UI component definitions (use organisms)

-## 9) Import Patterns
-
-### Atoms
-
-```tsx
-import Button from "@/components/atoms/buttons/Button";
-import Text from "@/components/atoms/typography/Text";
-```
-
-### Molecules
-
-```tsx
-import ProductCard from "@/components/molecules/cards/ProductCard";
-import FormField from "@/components/molecules/form-groups/FormField";
-```
-
-### Organisms
-
-```tsx
-import LoginForm from "@/components/organisms/forms/LoginForm";
-import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
-```
-
-### Templates
-
-```tsx
-import MainLayout from "@/components/templates/main-layout/MainLayout";
-```
-
-### Barrel Exports
-
-```tsx
-// Usage
-import { Button, Text } from "@/components/atoms";
-
-// components/atoms/index.ts
-export { default as Button } from "./buttons/Button";
-export { default as Text } from "./typography/Text";
-export * from "./buttons/Button.types";
-```
-
----
-
-## 10) Common Patterns
-
-### Creating a New Atom
-
-```tsx
-// atoms/buttons/NewButton.tsx
-export default function NewButton({ variant, ...props }: Props) {
-  return <button className={styles[variant]} {...props} />;
-}
-
-// atoms/buttons/NewButton.types.ts
-export interface Props extends ButtonHTMLAttributes<HTMLButtonElement> {
-  variant: "type1" | "type2";
-}
-```
-
-### Creating a New Molecule
-
-```tsx
-// molecules/cards/NewCard.tsx
-export default function NewCard({ item, onAction }: Props) {
-  const [hover, setHover] = useState(false);
-  return (
-    <div onMouseEnter={() => setHover(true)}>{/* atoms composition */}</div>
-  );
-}
-```
-
-### Creating a New Organism
-
-```tsx
-// organisms/sections/NewSection.tsx
-"use client";
-
-import ProductCard from "@/components/molecules/cards/ProductCard";
-import { useAuth } from "@/lib/auth-context";
-
-export default function NewSection() {
-  const { user } = useAuth();
-  // business logic, filtering, etc.
-  return <section>{/* molecules composition + logic */}</section>;
-}
-```
-
-### Creating a New Template
-
-```tsx
-// templates/layouts/NewTemplate.tsx
-export default function NewTemplate({ children, header }: Props) {
-  return (
-    <div className="layout">
-      <header>{header}</header>
-      <main>{children}</main>
-    </div>
-  );
-}
-```

-## 11) Testing & Documentation
-
-### For Each Component Level
-
-#### Atoms
-
-- Unit test: Props validation, styling
-- Storybook: All variants, all states
-- Doc: Props interface, usage examples
-
-#### Molecules
-
-- Integration test: Atoms composition
-- Storybook: Different molecule states
-- Doc: Props, behavior, dependencies
-
-#### Organisms
-
-- Integration test: With contexts mocked
-- E2E: User interactions
-- Doc: Logic flow, API integration points
-
-#### Templates
-
-- Layout test: Responsive grid layouts
-- Visual: Desktop/tablet/mobile
-- Doc: Layout structure, breakpoints
-
-#### Pages
-
-- E2E test: Full user flows
-- Performance: Metrics
-- Doc: Route, data flow, features
-
----
-
-## 12) Performance Optimization
-
-### Code Splitting
-
-- Atoms: Always bundled (small, frequently used)
-- Molecules: Bundled by page/feature
-- Organisms: Use `dynamic()` for heavy sections
-- Templates: Bundled by layout type
-- Pages: Automatic splitting by Next.js
-
-### Lazy Loading Example
-
-```tsx
-import dynamic from "next/dynamic";
-
-const ReviewModal = dynamic(
-  () => import("@/components/organisms/modals/ReviewModal"),
-  { loading: () => <Spinner /> },
-);
-```
-
-### Image Optimization
-
-- Use Next.js `Image` component (atoms/molecules)
-- Optimize with `priority` for above-fold
-- Use responsive sizes: `sizes="(max-width: 640px) 100vw, 50vw"`
-
----
-
-## 13) Accessibility
-
-### All Levels
-
-- Semantic HTML: `<button>`, `<a>`, `<form>`, `<nav>`
-- ARIA attributes: `aria-label`, `aria-expanded`, `role`
-- Keyboard navigation: Tab order, focus visible
-- Color contrast: WCAG AA minimum
-- Alt text: All images have meaningful `alt`
-
-### Example
-
-```tsx
-<button
-  aria-label="Add to cart"
-  className="focus:ring-2 focus:ring-blue-500 focus:ring-offset-2"
->
-  <CartIcon aria-hidden="true" />
-  Add to Cart
-</button>
-```

-# Feature Prompt: Register Shift (Đăng Ký Ca Làm)
-
-## Tổng Quan
-
-Xây dựng tính năng **Register Shift** cho phép nhân viên xem và đăng ký ca làm việc theo khung thời gian do quản lý tạo ra. Tính năng hỗ trợ cả hai vai trò: **Manager** và **Staff**, với giao diện responsive thích ứng theo kích thước màn hình.
-
----
-
-## Mục Đích
-
-- Cho phép nhân viên xem danh sách các khung thời gian ca làm khả dụng và đăng ký vào ca mà họ muốn làm.
-- Quản lý (Manager) có toàn quyền tạo, chỉnh sửa và xóa các khung thời gian ca làm.
-- Nhân viên có thể thấy ca làm của đồng nghiệp để tránh xung đột hoặc điều chỉnh lịch phù hợp.
-- Cả Manager và Staff đều có thể chỉnh sửa hoặc hủy ca đã đăng ký của nhân viên.
-
----
-
-## Vai Trò & Phân Quyền
-
-### Manager
-- Tạo, chỉnh sửa, xóa khung thời gian ca làm (shift slots).
-- Xem lịch làm việc của toàn bộ nhân viên theo tuần hoặc tháng.
-- Phê duyệt hoặc từ chối yêu cầu đăng ký ca.
-- Xóa hoặc thay đổi ca làm của bất kỳ nhân viên nào.
-- Gán ca làm cho nhân viên cụ thể nếu cần.
-
-### Staff (Nhân Viên)
-- Xem danh sách ca làm khả dụng trong tuần hoặc tháng.
-- Đăng ký vào ca mà mình muốn làm.
-- Xem ca đã được đăng ký bởi các nhân viên khác.
-- Hủy hoặc chỉnh sửa ca đã đăng ký của bản thân (trong giới hạn thời gian cho phép).
-
----
-
-## Yêu Cầu Giao Diện
-
-### Desktop (≥ 1024px) — Dạng Bảng Lịch Tuần/Tháng
-
-- Hiển thị lịch làm việc dạng **table theo tuần** (mặc định), với khả năng chuyển sang **xem theo tháng**.
-- Mỗi cột đại diện cho một ngày trong tuần (Mon–Sun).
-- Mỗi hàng đại diện cho một nhân viên hoặc một khung giờ.
-- Các ca làm được hiển thị dưới dạng **card màu** trong ô tương ứng, gồm:
-  - Tên ca / Khung giờ (ví dụ: `08:00 – 12:00`)
-  - Số giờ làm & mức lương dự kiến (ví dụ: `4h · 120k`)
-  - Trạng thái: `Available`, `Registered`, `Approved Leave`, `Absent`
-- **Bộ lọc tuần/tháng** ở góc trên, cho phép điều hướng qua lại giữa các tuần/tháng.
-- Hiển thị **tổng ngân sách tuần** (Weekly Budget) ở đầu bảng.
-- Nhóm nhân viên theo **department/role** (ví dụ: Bar Staff, Janitors,...).
-- Mỗi ca làm có thể click để xem chi tiết, chỉnh sửa hoặc xóa.
-
-#### Chế Độ Xem Theo Tháng (Month View)
-- Hiển thị dạng **calendar grid** (lưới 7 cột × ~5 hàng).
-- Mỗi ô ngày hiển thị số ca đã đăng ký hoặc dấu chấm màu trạng thái (tương tự ảnh tham khảo).
-- Cho phép nhân viên và manager tính toán ngày có thể nghỉ hoặc đăng ký ca xa hơn trong tháng.
-
----
-
-### Mobile (< 768px) — Dạng Lịch Dọc + Dot Indicator
-
-- Hiển thị **calendar theo tháng dạng nhỏ gọn** (compact calendar) ở đầu màn hình.
-  - Các ngày có ca làm được đánh dấu bằng **dot màu** phía dưới số ngày:
-    - 🟡 Vàng: Ca đang mở / khả dụng
-    - 🟢 Xanh lá: Ca đã được đăng ký
-    - ⚫ Xám: Không có ca
-  - Ngày hiện tại được highlight bằng vòng tròn (dark circle).
-- Khi chọn một ngày, hiển thị danh sách ca làm của ngày đó bên dưới.
-- Mỗi ca làm hiển thị dưới dạng **card dọc**:
-  - Khung giờ, số giờ, mức lương
-  - Tên nhân viên đã đăng ký (nếu có)
-  - Nút **Đăng ký** hoặc **Hủy đăng ký**
-- Điều hướng tháng bằng nút `<` và `>` ở hai bên tiêu đề tháng.

-## Trạng Thái Ca Làm (Shift Status)
-
-| Trạng Thái     | Màu             | Mô Tả                             |
-|----------------|-----------------|-----------------------------------|
-| Available      | Xanh dương nhạt | Ca đang mở, chưa có ai đăng ký    |
-| Registered     | Xanh dương đậm  | Nhân viên đã đăng ký ca này       |
-| Approved Leave | Tím/Lavender    | Nhân viên đã được duyệt nghỉ phép |
-| Absent         | Đỏ/Hồng         | Nhân viên vắng mặt không có lý do |
-

-
-## Luồng Chức Năng Chính
-
-### Staff — Đăng Ký Ca
-1. Truy cập màn hình Register Shift.
-2. Chọn tuần hoặc tháng muốn xem.
-3. Xem các ca làm khả dụng (Available).
-4. Click vào ca → Xem thông tin chi tiết (giờ, lương, số người đã đăng ký).
-5. Nhấn **Register** để đăng ký ca.
-6. Ca chuyển sang trạng thái **Registered**.
-
-### Manager — Tạo Ca Làm Mới
-1. Vào giao diện dashboard của manager.
-2. Vào giao diện lịch của nhóm/department.
-3. Click vào ô ngày muốn tạo ca.
-4. Nhập thông tin: Khung giờ bắt đầu – kết thúc, số lượng nhân viên cần, mức lương.
-5. Lưu → Ca hiển thị trên lịch với trạng thái **Available**.
-
-### Xóa / Chỉnh Sửa Ca
-- **Manager**: Có thể chỉnh sửa hoặc xóa bất kỳ ca nào của bất kỳ nhân viên nào.
-- **Staff**: Chỉ có thể hủy ca của bản thân, trong phạm vi thời gian cho phép (ví dụ: trước 24h so với giờ bắt đầu ca).

-## Dữ Liệu & Logic

-### Shift Slot Object
-```json
-{
-  "id": "shift_001",
-  "date": "2025-04-22",
-  "startTime": "08:00",
-  "endTime": "12:00",
-  "durationHours": 3.5,

-    { "id": "staff_01", "name": "Carol Saragosa" }
-  ],
-  "status": "registered"
-}
-```
-
----
-
-## Ghi Chú Bổ Sung
-
-- Nhân viên **không được đăng ký 2 ca trùng giờ** trong cùng một ngày.
-- Hệ thống cần hiển thị **cảnh báo xung đột** khi nhân viên cố đăng ký ca bị trùng lịch.
-- Cần hỗ trợ **thông báo (notification)** khi ca làm bị thay đổi hoặc bị hủy bởi manager.
