+---
+
+# Agent Orchestrator
+
+A skill for decomposing large engineering tasks into parallel and sequential
+sub-agents on Claude Code CLI using the **Task tool**.
+
+## When to Use
+
+Trigger when the user's task has **multiple distinct components** - for example:
+
+- "Build a REST API with authentication, rate limiting, and unit tests"
+- "Set up a monorepo with shared packages, CI pipeline, and deployment configs"
+- "Create a data pipeline: ingest transform store visualize"
+
+Do **not** trigger for single-step tasks (e.g., "rename this variable", "add a
+README").
+
+---
+
+## Prompt Template
+
+Copy the block below and paste it into your Agent Code CLI session. Replace the
+placeholder in the `TASK` variable with your actual task description.
+
+---
+
+```
+You are a senior engineering orchestrator operating inside the Agent Code CLI.
+
+TASK: "Build a login API with JWT and unit tests"
+
+---
+
+Your job is to analyze this task, decompose it into well-scoped sub-tasks, identify dependencies between them, and execute them using the Task tool.
+
+Follow these steps exactly:
+
+---
+
+## STEP 1 - Guard: Is this task complex enough?
+
+If the task can be completed in a single step by a single agent (e.g., "rename a variable", "write one function"), respond with:
+> "This task is simple enough to handle directly - no orchestration needed."
+Then complete it yourself. Stop here.
+
+Otherwise, continue.
+
+---
+
+## STEP 2 - Decompose the task into sub-tasks
+
+Analyze the TASK string. Break it into a flat list of concrete, independently scoped sub-tasks. Each sub-task must:
+- Have a clear, specific goal
+- Be executable by a single focused agent
+- Produce a concrete output (file, module, config, test suite, etc.)
+
+Output the list in this format:
+
+Sub-tasks:
+  [T1] <sub-task title> - <one-sentence description>
+  [T2] <sub-task title> - <one-sentence description>
+  [T3] ...
+
+---
+
+## STEP 3 - Identify dependencies and execution mode
+
+For each sub-task, decide whether it can run in parallel with others, or must run after a specific predecessor.
+
+Label each sub-task as one of:
+  [PARALLEL]               - no dependencies, can start immediately
+  [SEQUENTIAL - after Tx]  - must run only after sub-task Tx completes
+
+Rules:
+- If a sub-task depends on an artifact produced by another (a file, schema, interface, module), mark it SEQUENTIAL.
+- If two sub-tasks are fully independent (different files, no shared state), mark both PARALLEL.
+- Do not start any SEQUENTIAL sub-task until its prerequisite is confirmed complete.
+
+Output the dependency plan in this format:
+
+Dependency Plan:
+  [T1] <title>    [PARALLEL]
+  [T2] <title>    [PARALLEL]
+  [T3] <title>    [SEQUENTIAL - after T1]
+  [T4] <title>    [SEQUENTIAL - after T2, T3]
+
+---
+
+## STEP 4 - Confirm plan before execution
+
+Print the full decomposition and dependency plan to the user.
+Then print:
+> "Starting execution. Spawning parallel sub-agents now..."
+
+Do not skip this confirmation step.
+
+---
+
+## STEP 5 - Execute using the Task tool
+
+Use the **Task tool** to spawn sub-agents. Follow this protocol:
+
+### 5a. Spawn all [PARALLEL] sub-tasks simultaneously
+- Call the Task tool for each PARALLEL sub-task at the same time (do not wait for one to finish before spawning the next).
+- Each Task call must include a self-contained prompt describing exactly what to build, where to put files, and what the expected output is.
+
+### 5b. Monitor and gate SEQUENTIAL sub-tasks
+- Wait for each prerequisite Task to complete before spawning its dependent.
+- Once a prerequisite completes, immediately spawn the next Task.
+
+### 5c. Task prompt format
+Each task spawned via the Task tool must include:
+
+  - Role: "You are a focused sub-agent. Complete exactly this sub-task and nothing else."
+  - Sub-task goal (from Step 2)
+  - Output location (file path or module name)
+  - Any relevant interfaces or contracts from predecessor tasks (if SEQUENTIAL)
+  - Instruction to report back: "When done, summarize what you built and list output files."
+
+---
+
+## STEP 6 - Synthesize and report
+
+After all Tasks complete:
+1. Collect each sub-agent's summary.
+2. Verify that all expected outputs exist.
+3. Report to the user:
+   - What was built
+   - File/module structure
+   - Any issues or gaps found
+   - Suggested next steps (e.g., "Run `npm test` to verify", "Review the generated OpenAPI spec")
+
+---
+
+Begin now with STEP 1.
+```
+
+---
+
+## Tips for Customizing the Template
+
+- **Replace the TASK value** with your actual task string. Keep it on one line,
+  in quotes.
+- **Add context if needed**: Append lines after `TASK:` like
+  `STACK: "Node.js, PostgreSQL, Jest"` or
+  `CONSTRAINTS: "Use ESM modules only"` - the orchestrator will incorporate
+  them.
+- **For monorepos or specific file layouts**: Add a `STRUCTURE:` hint, e.g.:
+  ```
+  STRUCTURE: "src/api/, src/auth/, src/tests/, docker-compose.yml"
+  ```
+- **To limit parallelism** (e.g., on resource-constrained machines): Add
+  `MAX_PARALLEL_AGENTS: 2` after the TASK line.
+
+---
+
+## Example Usage
+
+**Input task:**
+
+> "Build a login API with JWT authentication and unit tests"
+
+**Expected orchestrator output (before execution):**
+
+```
+Sub-tasks:
+  [T1] Project scaffold - Initialize Node.js project, folder structure, and dependencies
+  [T2] Database schema - Define User model and migration for PostgreSQL
+  [T3] Auth service - Implement JWT sign/verify logic and password hashing
+  [T4] Login route - Build POST /auth/login endpoint with validation
+  [T5] Middleware - Create JWT auth middleware for protected routes
+  [T6] Unit tests - Write Jest tests for auth service and login route
+
+Dependency Plan:
+  [T1] Project scaffold      [PARALLEL]
+  [T2] Database schema       [PARALLEL]
+  [T3] Auth service          [SEQUENTIAL - after T1]
+  [T4] Login route           [SEQUENTIAL - after T3]
+  [T5] Middleware            [SEQUENTIAL - after T3]
+  [T6] Unit tests            [SEQUENTIAL - after T4, T5]
+
+Starting execution. Spawning parallel sub-agents now...
+```
+
+T1 and T2 spawn immediately. T3 spawns once T1 completes. T4 and T5 spawn once
+T3 completes. T6 spawns last.
+
+---
+
+## Notes
+
+- This skill requires Agent Code CLI with the **Task tool** enabled.
+- Each spawned sub-agent has no memory of the others - pass all needed context
+  explicitly in the Task prompt.
+- For very large tasks (10+ sub-tasks), consider breaking the orchestration into
+  phases and applying this skill recursively per phase.

+
+# 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)
+- [ ] Mobile-first approach
+- [ ] No hardcoded values (use Tailwind config)

+
+# 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)
+  - [ ] All elements render correctly at 375x667 (mobile)
+  - [ ] Colors match design specifications
+  - [ ] Typography renders correctly (font families, sizes, weights)
+  - [ ] Images load and display at correct aspect ratios
+
+- [ ] **Responsive Behavior**
+  - [ ] Layout adapts correctly on mobile (no horizontal scroll)
+  - [ ] Navigation collapses/expands appropriately
+  - [ ] Form inputs are touch-friendly (min 44x44px)
+  - [ ] Content reflows without overlapping
+
+- [ ] **Interactive Elements**
+  - [ ] All buttons are clickable and have hover states
+  - [ ] Form inputs accept user input
+  - [ ] Dropdowns open/close correctly
+  - [ ] Links are underlined and properly colored
+
+- [ ] **Accessibility**
+  - [ ] Keyboard navigation works (Tab key)
+  - [ ] Color contrast meets WCAG AA standards
+  - [ ] Images have alt text
+  - [ ] Form labels are associated with inputs
+
+- [ ] **Critical User Paths**
+  - [ ] [Specific path 1]: [Steps and expected result]
+  - [ ] [Specific path 2]: [Steps and expected result]
+
+### Step 5: Generate Test Report
+
+Create an HTML/Markdown report with:
+
+```markdown
+# UI/UX Testing Report

+
+## 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

+# AGENTS GUIDE (Updated with Atomic Design)
+
+## 1) Kiến trúc project
+
+Dự án sử dụng **Next.js App Router** với **Atomic Design Pattern** cho UI
+components.
+
+### `app/` - Routes & Pages
+
+Chứa route/page/layout theo Next.js App Router.
+
+- **`layout.tsx`** - Root layout toàn app (Header + Providers + Footer wrapper)
+- **`providers.tsx`** - Client component gắn 3 providers: AuthProvider,
+  MenuProvider, CartProvider
+- **`globals.css`** - Global styles + CSS variables + Tailwind imports
+- **Route groups:**
+  - **`(main)/`** - Main shopping interface (duyệt menu, đăng nhập, đăng ký,
+    thanh toán)
+  - **`(feed)/`** - Feed/discovery page (khám phá quán)
+  - **`(manager)/`** - Manager dashboard (quản lý sản phẩm, phân tích tài
+    chính) - **[ĐANG PHÁT TRIỂN ~70%]**
+  - **`(staff)/`** - Staff shift schedule (lịch làm việc nhân viên) - **[HOÀN
+    THÀNH]**
+- **Tài liệu:** `app/APP.md` - Chi tiết routes, pages, CSS tokens
+
+### `components/` - Reusable UI Components (Atomic Design)
+
+Chứa UI components được tổ chức theo **Atomic Design Pattern** với 5 cấp độ:
+
+#### **ATOMS** (`components/atoms/`)
+
+**Khối xây dựng cơ bản, không chia nhỏ hơn được.**
+
+Các component cơ bản, tái sử dụng cao, không logic phức tạp:
+
+- **`buttons/`** - Button, IconButton
+- **`inputs/`** - TextInput, NumberInput, Checkbox
+- **`badges/`** - Badge, PriceBadge, StatusBadge
+- **`icons/`** - StarIcon, CartIcon, SearchIcon, etc.
+- **`typography/`** - Heading, Text, Caption
+- **`dividers/`** - Divider
+- **`loaders/`** - Spinner, Skeleton
+
+**Đặc điểm:**
+
+- ✅ Pure props-based, no logic
+- ✅ Full TypeScript typing
+- ✅ Reusable across entire project
+- ✅ No context/hooks
+- 📄 Tài liệu: `components/atoms/ATOMS.md`
+
+#### **MOLECULES** (`components/molecules/`)
+
+**Nhóm atoms đơn giản hoạt động cùng nhau.**
+
+Kết hợp multiple atoms, có thể có state đơn giản (open/close):
+
+- **`form-groups/`** - FormField (input + label + error)
+- **`cards/`** - ProductCard, ShopCard, ReviewCard
+- **`ratings/`** - RatingStars, RatingInput
+- **`price-display/`** - PriceTag, PriceRange
+- **`search-bar/`** - SearchInput, SearchBar
+- **`breadcrumb/`** - Breadcrumb
+- **`tabs/`** - TabGroup, Tab
+
+**Đặc điểm:**
+
+- ✅ Combines atoms
+- ✅ Simple state (useState for UI)
+- ✅ No business logic
+- ✅ Reusable in multiple contexts
+- ❌ No global context (useAuth, useCart)
+- 📄 Tài liệu: `components/molecules/MOLECULES.md`
+
+#### **ORGANISMS** (`components/organisms/`)
+
+**Khu vực UI phức tạp, riêng biệt, có logic riêng.**
+
+Sections phức tạp kết hợp molecules + atoms, có logic, data filtering:
+
+- **`navigation/`** - Navbar, CategoryMenu
+- **`cart/`** - CartFab, CartSummary, CartList
+- **`product-grid/`** - ProductGrid, ProductFilters
+- **`forms/`** - LoginForm, RegisterForm, CheckoutForm, ReviewForm
+- **`modals/`** - ReviewModal, ConfirmModal, CashPaymentModal, QRPaymentModal,
+  PaymentSuccessModal
+- **`manager/`** - ProductModal (image upload), ComboModal, CategoryModal,
+  DeleteConfirm, StatusBadge, ProductsTab, CombosTab, CategoriesTab
+- **`analytics/`** - BarChart, LineChart, PieChart (SVG), ProductTable,
+  SummaryCard
+- **`shift-schedule/`** - WeeklySchedule, MonthlyCalendar, MobileShiftView,
+  ShiftCreateModal, ShiftDetailModal
+- **`shop-grid/`** - ShopGrid, ShopFilters
+- **`hero-section/`** - HeroSection
+- **`featured-section/`** - FeaturedProducts, FeaturedShops
+
+**Đặc điểm:**
+
+- ✅ Complex UI sections
+- ✅ Can use contexts (useAuth, useCart, useMenu)
+- ✅ Business logic (filtering, sorting)
+- ✅ Always "use client"
+- ❌ Not directly reusable (section-specific)
+- 📄 Tài liệu: `components/organisms/ORGANISMS.md`
+
+#### **TEMPLATES** (`components/templates/`)
+
+**Bố cục cấp trang, cấu trúc nội dung.**
+
+Page layouts, không có data cụ thể, children composition:
+
+- **`main-layout/`** - MainLayout (header + sidebar + content + footer)
+- **`feed-layout/`** - FeedLayout
+- **`manager-layout/`** - ManagerLayout
+- **`staff-layout/`** - StaffLayout (navigation shell for staff pages)
+- **`checkout-layout/`** - CheckoutLayout
+- **`auth-layout/`** - AuthLayout
+
+**Đặc điểm:**
+
+- ✅ Page-level layout structure
+- ✅ Composition of organisms
+- ✅ No data fetching
+- ✅ Children prop pattern
+- ❌ No hardcoded data
+- 📄 Tài liệu: `components/templates/TEMPLATES.md`
+
+#### **PAGES** (`app/*/page.tsx`)
+
+**Phiên bản cụ thể với dữ liệu thật.**
+
+Route-specific pages, sử dụng templates + organisms:
+
+- **`app/(main)/page.tsx`** - Main shopping page
+- **`app/(main)/checkout/page.tsx`** - Checkout page
+- **`app/(feed)/page.tsx`** - Feed/discovery page
+- **`app/(manager)/products/page.tsx`** - Manager dashboard
+
+**Đặc điểm:**
+
+- ✅ Route-specific logic
+- ✅ Data integration
+- ✅ Context usage
+- ✅ State orchestration
+- ❌ No UI component definitions
+
+**Tài liệu chi tiết:**
+
+- `components/ATOMIC_DESIGN.md` - Full Atomic Design structure guide
+- `components/atoms/ATOMS.md` - Atoms inventory & props
+- `components/molecules/MOLECULES.md` - Molecules inventory & usage
+- `components/organisms/ORGANISMS.md` - Organisms inventory & logic
+- `components/templates/TEMPLATES.md` - Templates structure
+
+### `layouts/` - Layout Components
+
+Chứa layout cấp root (không phải Atomic Design templates):
+
+- **`header.tsx`** - Sticky top bar với brand (logo + shop name) + auth status
+- **`footer.tsx`** - Footer với 3 sections: brand info, social links, WiFi card
+- **Tài liệu:** `layouts/LAYOUTS.md` - Responsive design, CSS variables
+
+### `lib/` - Shared Logic & Data
+
+Chứa logic dùng chung, context, constants, types:
+
+- **`types.ts`** - TypeScript interfaces: User, Product, MenuCategory, Shop,
+  ShopInfo
+- **`constants.ts`** - Mock data: MOCK_PRODUCTS (18 items), MOCK_SHOPS (5),
+  MOCK_USERS, MENU_CATEGORIES (8), SHOP_INFO, SOCIAL_LINKS
+- **`auth-context.tsx`** - AuthProvider + useAuth() hook (login, logout,
+  register)
+- **`cart-context.tsx`** - CartProvider + useCart() hook (add, remove, quantity
+  operations, clearCart)
+- **`menu-context.tsx`** - MenuProvider + useMenu() hook (category state)
+- **`manager-context.tsx`** - ManagerProvider + useManager() hook (CRUD for
+  products, combos, categories)
+- **`shift-context.tsx`** - ShiftProvider + useShift() hook (staff shift
+  management: create, update, delete, date selection)
+- **Tài liệu:** `lib/LIB.md` - Chi tiết types, constants, contexts
+
+### `public/` - Static Assets
+
+Chứa static assets:
+
+- **`favicon/`** - Favicon files
+- **`imgs/`** - Logo, product images (organized in `products/` subfolder)
+
+### `scripts/` - Internal Scripts
+
+Chứa script nội bộ:
+
+- **`release.ts`** - Semantic release script
+
+### `types/` - Global Types
+
+Chứa type dùng chung cấp project:
+
+- **`css.d.ts`** - TypeScript declarations cho CSS modules
+
+### Root Config Files
+
+- **`package.json`** - Dependencies (Next.js 16.1.7, React 19.2.3, Tailwind
+  4.2.2, TypeScript)
+- **`tsconfig.json`** - TypeScript config
+- **`next.config.ts`** - Next.js config
+- **`tailwind.config.ts`** - Tailwind CSS config (v4)
+- **`postcss.config.mjs`** - PostCSS config
+- **`eslint.config.ts`** - ESLint rules
+- **`.prettierrc`** - Prettier formatting
+- **`release.config.ts`** - Semantic release config
+
+---
+
+## 2) Code convention (Naming, format, style guide)
+
+### Naming & File Organization
+
+- **React components:** `PascalCase` (e.g., `Button.tsx`, `ProductCard.tsx`)
+- **Context/util files:** `kebab-case` (e.g., `auth-context.tsx`,
+  `menu-context.tsx`)
+- **Type files:** `ComponentName.types.ts` (e.g., `Button.types.ts`)
+- **Variables/functions:** `camelCase`
+- **Types/Interfaces:** `PascalCase`
+- **Routes:** Follow folder structure in `app/` (URL = folder path)
+- **Imports:** Use absolute paths with `@/` alias (e.g.,
+  `import { Button } from "@/components/atoms/buttons/Button"`)
+

+```
+
+### Format & Linting
+
+- **Language:** TypeScript (.ts, .tsx) for all files
+- **Formatter:** Prettier (config: `.prettierrc`)
+  - Import sorting: `@trivago/prettier-plugin-sort-imports`
+  - Tailwind class sorting: `prettier-plugin-tailwindcss`
+- **Linter:** ESLint (config: `eslint.config.ts`, extends `next` rules)
+- **Code style:**
+  - Clear, self-documenting code
+  - Separate concerns by module/file
+  - Avoid code duplication
+  - Keep imports clean (no dead code)
+  - Use `"use client"` only where needed (interactive components)
+
+### Styling & UI
+
+- **Framework:** Tailwind CSS v4.2.2
+- **CSS Variables:** Defined in `globals.css` at `:root`
+  - Colors: `--color-primary`, `--color-primary-dark`, `--color-accent`,
+    `--color-bg-*`, `--color-text-*`, `--color-border-*`, `--color-shadow-*`
+  - Spacing: `--spacing-header-height` (72px)
+  - Use in Tailwind: `bg-[color:var(--color-primary)]`,
+    `text-[color:var(--color-text-primary)]`
+- **Icons:** FontAwesome (free CDN icons via `<i class="fa-solid fa-...">`)
+- **Images:** Next.js `Image` component from `next/image`
+- **Dark mode:** CSS variables support dark mode (can override `:root` values in
+  `@media (prefers-color-scheme: dark)`)
+
+### Responsive Design
+
+- **Breakpoints (Tailwind):** sm (640px), md (768px), lg (1024px), xl (1280px),
+  2xl (1536px)
+- **Every new UI feature must be responsive:**
+  - Mobile (<640px): Single column, stacked layout, collapsed sidebar
+  - Tablet (640px-1024px): 2-column layout, adjusted grid
+  - Desktop (1024px+): Multi-column, expanded sidebar, comfortable spacing
+- **Mobile-first approach:** Write base styles for mobile, then add `sm:`,
+  `md:`, `lg:`, `xl:` prefixes for larger screens
+- **Example:** `className="w-full sm:w-1/2 md:w-1/3 lg:w-1/4"`
+

+
+## 3) Quy tắc quan trọng
+
+### Markdown Documentation Updates
+
+**Luôn update các file markdown trong folder liên quan khi hoàn thành task:**
+
+| Folder Modified         | Update File                         | Content to Add/Update                       |
+| ----------------------- | ----------------------------------- | ------------------------------------------- |
+| `components/atoms/`     | `components/atoms/ATOMS.md`         | Atom props, variants, usage examples        |
+| `components/molecules/` | `components/molecules/MOLECULES.md` | Molecule props, composition, usage          |
+| `components/organisms/` | `components/organisms/ORGANISMS.md` | Organism logic, contexts used, features     |
+| `components/templates/` | `components/templates/TEMPLATES.md` | Template structure, responsive layout       |
+| `app/`                  | `app/APP.md`                        | Routes, pages, CSS tokens                   |
+| `layouts/`              | `layouts/LAYOUTS.md`                | Layout structure, responsive patterns       |
+| `lib/`                  | `lib/LIB.md`                        | New types, constants, contexts              |
+| **Root**                | `ATOMIC_DESIGN.md`                  | Overall structure, patterns, best practices |
+
+**Quy trình:**
+
+1. Hoàn thành task/feature
+2. Update file `.md` tương ứng trong folder
+3. Commit code + markdown updates cùng lúc
+4. Push to branch
+
+### Type Safety & Data Flow
+
+- **Always use TypeScript** - no plain `any` types
+- **Mock data first** - Use `lib/constants.ts` for development, replace with API
+  later
+- **Contexts for state sharing:**
+  - `AuthContext` (lib/auth-context.tsx) - User state + auth operations →
+    `useAuth()`
+  - `CartContext` (lib/cart-context.tsx) - Shopping cart + operations →
+    `useCart()` (includes `clearCart`)
+  - `MenuContext` (lib/menu-context.tsx) - Active category state → `useMenu()`
+  - `ManagerContext` (lib/manager-context.tsx) - Manager dashboard state (CRUD
+    for products/combos/categories) → `useManager()`
+  - `ShiftContext` (lib/shift-context.tsx) - Staff shift management (create,
+    update, delete shifts, date selection) → `useShift()`
+- **localStorage keys:** `coffee-shop-user`, `coffee-shop-cart` (defined in
+  contexts)
+
+### Component Development (Atomic Design)
+
+#### Creating an Atom
+
+1. Identify the basic building block needed (button, input, text, icon)
+2. Create `atoms/category/ComponentName.tsx`
+3. Create `atoms/category/ComponentName.types.ts` with props interface
+4. No business logic, pure props-based
+5. Add to `atoms/index.ts` barrel export
+6. Document in `atoms/ATOMS.md`
+
+```tsx
+// Example: atoms/buttons/Button.tsx
+import type { ButtonProps } from "./Button.types";
+
+export default function Button({ variant = "primary", ...props }: ButtonProps) {
+  return <button className={variants[variant]} {...props} />;
+}
+```
+
+#### Creating a Molecule
+
+1. Identify which atoms compose this molecule
+2. Create `molecules/category/ComponentName.tsx`
+3. Create `molecules/category/ComponentName.types.ts`
+4. Can use useState for simple UI state
+5. No global context usage
+6. Add to `molecules/index.ts` barrel export
+7. Document in `molecules/MOLECULES.md`
+
+```tsx
+// Example: molecules/cards/ProductCard.tsx
+"use client";
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+import type { ProductCardProps } from "./Card.types";
+
+export default function ProductCard({
+  product,
+  onAddToCart,
+}: ProductCardProps) {
+  return (
+    <div className="rounded-lg border">
+      {/* atoms composition */}
+      <Button onClick={() => onAddToCart(product)}>Add</Button>
+    </div>
+  );
+}
+```
+
+#### Creating an Organism
+
+1. Identify complex section (product grid, form, modal content)
+2. Create `organisms/section-type/ComponentName.tsx`
+3. Create `organisms/section-type/ComponentName.types.ts`
+4. Can use contexts (useAuth, useCart, useMenu)
+5. Contains business logic (filtering, sorting, validation)
+6. Always use `"use client"`
+7. Add to `organisms/index.ts` barrel export
+8. Document in `organisms/ORGANISMS.md`
+
+```tsx
+// Example: organisms/product-grid/ProductGrid.tsx
+"use client";
+import { useCart } from "@/lib/cart-context";
+import { useMenu } from "@/lib/menu-context";
+import ProductCard from "@/components/molecules/cards/ProductCard";
+
+export default function ProductGrid() {
+  const { activeCategory } = useMenu();
+  const { addToCart } = useCart();
+
+  const filtered = products.filter(p =>
+    activeCategory === "all" || p.category === activeCategory
+  );
+
+  return (
+    <div className="grid grid-cols-1 md:grid-cols-3">
+      {filtered.map(p => <ProductCard key={p.id} {...} />)}
+    </div>
+  );
+}
+```
+
+#### Creating a Template
+
+1. Identify page-level layout structure
+2. Create `templates/layout-type/TemplateName.tsx`
+3. Create `templates/layout-type/TemplateName.types.ts`
+4. No data fetching, purely structural
+5. Compose organisms + layout sections
+6. Use children prop pattern
+7. Add to `templates/index.ts` barrel export
+8. Document in `templates/TEMPLATES.md`
+
+```tsx
+// Example: templates/main-layout/MainLayout.tsx
+import Navbar from "@/components/organisms/navigation/Navbar";
+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">
+        <nav className="hidden w-64 md:block">
+          <Navbar />
+        </nav>
+        <main className="flex-1">{children}</main>
+      </div>
+    </div>
+  );
+}
+```
+
+### Client vs Server Components
+
+- **Atoms:** Server by default, `"use client"` if interactive (Button, Input)
+- **Molecules:** `"use client"` if state needed, server if pure display
+- **Organisms:** Always `"use client"` (logic, contexts)
+- **Templates:** Server by default (layout), children can be client
+- **Pages:** Depends on needs (route-specific logic = client)
+
+### Testing & Quality
+
+- **Responsive testing:** Test on mobile (< 640px), tablet (768px), desktop
+  (1024px+)
+- **Accessibility:** Images have alt text, buttons have semantic HTML,
+  sufficient contrast
+- **Performance:** Use Next.js Image component, optimize imports, lazy-load
+  organisms
+- **Error handling:** Validate user input at system boundaries
+
+### Git & Commits
+
+- **Commit message:** Follow conventional commits (`feat:`, `fix:`, `docs:`,
+  `style:`, `refactor:`)
+- **Before pushing:** Ensure `npm run lint` and `npm run format` pass locally
+- **Markdown updates:** Include in same commit as code changes
+- **Branch naming:** Feature branches = `feature_<name>` (e.g.,
+  `feature_atomic_refactor`)

+## 4) Quick Reference Guide for AI
+
+### Atomic Design Cheat Sheet
+
+```
+ATOM              → Basic building block (Button, Text, Icon)
+MOLECULE          → Atoms group (ProductCard, FormField)
+ORGANISM          → Complex section (ProductGrid, LoginForm)
+TEMPLATE          → Page layout (MainLayout, CheckoutLayout)
+PAGE              → Specific route (app/*/page.tsx)
+```
+
+### Component Decision Tree
+
+```
+Is it a basic UI element?
+  ├─ YES → ATOM (Button, Text, Icon, Input, Badge)
+  └─ NO → Is it a composition of atoms?
+          ├─ YES → MOLECULE (Card, FormField, SearchBar)
+          └─ NO → Is it a complex section with logic/context?
+                  ├─ YES → ORGANISM (ProductGrid, LoginForm, Modal)
+                  └─ NO → Is it a page-level layout?
+                          ├─ YES → TEMPLATE (MainLayout, CheckoutLayout)
+                          └─ NO → PAGE (app/page.tsx)
+```
+
+### Creating a New Component Checklist
+
+- [ ] Determine component level (Atom/Molecule/Organism/Template)
+- [ ] Create directory: `components/[level]/[category]/`
+- [ ] Create `ComponentName.tsx` with TypeScript
+- [ ] Create `ComponentName.types.ts` with Props interface
+- [ ] Add to `index.ts` barrel export in that level
+- [ ] Test responsive design (mobile/tablet/desktop)
+- [ ] Update markdown documentation
+- [ ] Run `npm run format` and `npm run lint`
+- [ ] Commit with conventional message
+
+### Common File Locations
+
+- **Atoms:** `components/atoms/[category]/ComponentName.tsx`
+- **Molecules:** `components/molecules/[category]/ComponentName.tsx`
+- **Organisms:** `components/organisms/[section-type]/ComponentName.tsx`
+- **Templates:** `components/templates/[layout-type]/TemplateName.tsx`
+- **Pages:** `app/[route]/page.tsx`
+- **Layouts (root):** `layouts/header.tsx`, `layouts/footer.tsx`
+- **Contexts:** `lib/auth-context.tsx`, `lib/cart-context.tsx`
+- **Types:** `lib/types.ts`
+- **Constants:** `lib/constants.ts`
+
+### Import Patterns
+
+```tsx
+// Atoms
+import Button from "@/components/atoms/buttons/Button";
+import { Button } from "@/components/atoms"; // via barrel
+
+// Molecules
+import ProductCard from "@/components/molecules/cards/ProductCard";
+import { ProductCard } from "@/components/molecules";
+
+// Organisms
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+import { ProductGrid } from "@/components/organisms";
+
+// Templates
+import MainLayout from "@/components/templates/main-layout/MainLayout";
+import { MainLayout } from "@/components/templates";
+
+// Contexts
+import { useAuth } from "@/lib/auth-context";
+import { useCart } from "@/lib/cart-context";
+```
+
+### CSS Variables (from `globals.css`)
+
+```css
+/* Colors */
+--color-primary: main brand color --color-primary-dark: darker shade
+  --color-accent: secondary color --color-bg-main: main background
+  --color-bg-card: card background --color-bg-sidebar: sidebar background
+  --color-text-primary: main text color --color-text-secondary: secondary text
+  --color-text-muted: gray/muted text --color-border: border color
+  --color-border-light: light border --color-shadow-sm: small shadow
+  --color-shadow-md: medium shadow /* Spacing */ --spacing-header-height: 72px;
+```
+
+### Useful Commands
+
+```bash
+# Development
+npm run dev              # Start dev server
+
+# Code quality
+npm run lint            # Run ESLint
+npm run format          # Format code with Prettier
+
+# Build & Deploy
+npm run build           # Build for production
+npm start               # Start production server
+
+# Release
+npm run release         # Semantic release (auto-version + changelog)
+```
+
+### Common Patterns
+
+**Filtering products by category (in Organism):**
+
+```tsx
+const filtered = MOCK_PRODUCTS.filter(
+  (p) => activeCategory === "all" || p.category === activeCategory,
+);
+```
+
+**Using Atoms in Molecules:**
+
+```tsx
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+export default function Card() {
+  return (
+    <div>
+      <Text variant="body1">Product Name</Text>
+      <Button onClick={handleClick}>Add</Button>
+    </div>
+  );
+}
+```
+
+**Using Organisms in Templates:**
+
+```tsx
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+
+export default function MainLayout({ children }) {
+  return (
+    <div>
+      <header>Header</header>
+      <ProductGrid />
+      {children}
+    </div>
+  );
+}
+```
+
+**Responsive classes (all levels):**
+
+```tsx
+// Mobile-first: base style applies to all, sm:/md:/lg: apply at breakpoints
+className = "w-full sm:w-1/2 md:w-1/3 p-4 md:p-6 hidden md:block";
+```
+

+
+## 🚀 Next Steps (Phase 2)
+
+### Molecules to Create
+
+1. **ProductCard** - Image + Text + Badge + Button
+2. **FormField** - Label + Input + Error + Validation
+3. **SearchBar** - SearchInput + Button
+4. **RatingInput** - Interactive 5-star rating
+5. **PriceTag** - Price formatting molecule
+
+**Estimated Time:** 2-3 days
+
+---
+
+## 💡 Design Decisions
+
+### Why Barrel Exports?
+
+```tsx
+// ❌ Bad: Scattered imports
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+// ✅ Good: Single clean import
+import { Button, Text } from "@/components/atoms";
+```
+
+### Why TypeScript Types in Separate Files?
+
+- Clear separation of concerns
+- Easier to maintain interfaces
+- Reusable types across modules
+- Better for large components
+
+### Why CSS Variables?
+
+- Single point for theme changes
+- Easy dark mode switching
+- Consistent across all atoms
+- No inline style duplication
+
+---
+

 ### 4. Payment Page (app/(main)/payment/page.tsx)
 
-**Route:** `/payment` **Type:** Client component (TBD) **Description:**
-Payment/checkout page. Currently a placeholder; implement when cart and order
-system are ready.
+**Route:** `/payment` **Type:** Client component **Description:**
+Payment/checkout page. Shows cart items in a table with quantity controls and a
+summary aside (PaymentSummaryCard) with payment actions and modal flows.
+
+#### Key Features
+
+- **Cart Table:**
+  - Lists all cart items (name, price, description, quantity controls, delete)
+  - Quantity input with +/- buttons and direct number input
+  - Empty state message when cart is empty
+  - Horizontal scroll on small screens (min-w-190)
+
+- **PaymentSummaryCard (Invoice Aside):**
+  - Sticky on desktop (top offset = header height + 1rem)
+  - Shows all cart items with subtotals and grand total
+  - Payment method buttons: Tiền mặt (Cash), QR Code
+  - **"Đánh giá" button** — only visible when `user.role === "customer"`; opens
+    ReviewModal
+  - **"Quay về" button** — links back to `/`; spans full width when review
+    button is absent
+
+#### Payment Modal Flow
+
+- **Cash Payment (CashPaymentModal):**
+  - Opened when user clicks "Tiền mặt"
+  - Input: cash received amount
+  - Shows change due or insufficient cash error inline
+  - Displays invoice item list
+  - Confirm → opens PaymentSuccessModal
+
+- **QR Payment (QRPaymentModal):**
+  - Opened when user clicks "QR Code"
+  - Generates QR code via `qrcode.react` (`QRCodeSVG` component)
+  - 5-second countdown timer — auto-confirms on expiry
+  - Displays invoice item list
+  - Confirm → opens PaymentSuccessModal
+
+- **PaymentSuccessModal:**
+  - Shown after confirming Cash or QR payment
+  - Displays success confirmation message
+  - Clears cart via `clearCart()` from CartContext on close/confirm
+
+- **ReviewModal:**
+  - Opened when a customer clicks "Đánh giá"
+  - 5-star rating + textarea for comment
+  - Closed via "Quay lại" button, backdrop click, or after submitting
+  - See `components/ReviewModal.tsx` for full documentation
+
+#### Context Usage
+
+- **useCart()** — items, totalPrice, increaseQty, decreaseQty, removeFromCart,
+  setQuantity, clearCart
+- **useAuth()** — user (to check `user.role === "customer"` for review button
+  visibility)
+
+#### State Management
+
+```tsx
+isReviewOpen: boolean; // Controls ReviewModal visibility
+isCashModalOpen: boolean; // Controls CashPaymentModal visibility
+isQRModalOpen: boolean; // Controls QRPaymentModal visibility
+isSuccessModalOpen: boolean; // Controls PaymentSuccessModal visibility
+isCustomer: boolean; // Derived from user.role === "customer"
+```
+
+#### Responsive Behavior
+
+- **Mobile:** Single column layout, table scrolls horizontally, button labels
+  hidden (icon only)
+- **Desktop (lg+):** Button labels visible, aside becomes sticky sidebar (xl:
+  w-85)
+- **Review button grid:** When customer is logged in, 3 buttons in 2-column
+  grid; "Quay về" occupies remaining space. Otherwise 2-column grid with "Quay
+  về" spanning full width.

+# Atoms Components Library
+
+**Status:** ✅ Complete — 14 atoms **Created:** 2026-04-03 **Foundation:**
+Atomic Design Pattern
+
+---
+
+## 📚 Overview
+
+Atoms are the basic building blocks of your UI. They are small, focused,
+reusable components that have no dependencies on other components (except
+potentially other atoms).
+
+**Key Principles:**
+
+- ✅ No business logic
+- ✅ No context/hooks (useAuth, useCart, etc.)
+- ✅ Pure props-based
+- ✅ Full TypeScript typing
+- ✅ CSS variables for theming
+- ✅ Accessible by default
+
+---

+## 🎨 Theming
+
+All atoms use CSS variables for consistent theming:
+
+```css
+/* Colors */
+--color-primary
+--color-primary-dark
+--color-accent
+--color-accent-light
+--color-bg-card
+--color-text-primary
+--color-text-secondary
+--color-text-muted
+--color-border
+--color-border-light
+--color-shadow-sm
+--color-shadow-md
+```
+
+Change one variable in `globals.css` to update all atoms across the app.
+
+---
+
+## 🔄 Import Patterns
+
+### Individual Imports
+
+```tsx
+import { Badge, PriceBadge } from "@/components/atoms/badges";
+import { Button } from "@/components/atoms/buttons";
+import { Divider } from "@/components/atoms/dividers";
+import ErrorMessageLogin from "@/components/atoms/errors/ErrorMessageLogin";
+import { LoginInput, SearchInput, TextInput } from "@/components/atoms/inputs";
+import { Caption, Heading, Text } from "@/components/atoms/typography";
+```
+
+### Barrel Exports (Recommended)
+
+```tsx
+import {
+  Badge,
+  Button,
+  Caption,
+  Divider,
+  Heading,
+  IconButton,
+  PriceBadge,
+  SearchInput,
+  Text,
+  TextInput,
+  Textarea,
+} from "@/components/atoms";
+```
+
+> Note: `ErrorMessageLogin` and `LoginInput` are imported directly from their
+> subfolders as they are auth-specific and not re-exported from the root barrel.
+
+### Type Imports
+
+```tsx
+import type {
+  ButtonProps,
+  HeadingProps,
+  TextInputProps,
+} from "@/components/atoms";
+```

+## ✅ Usage Examples
+
+### Form Field
+
+```tsx
+<div className="space-y-4">
+  <TextInput label="Name" placeholder="Enter your name" type="text" />
+  <TextInput
+    label="Email"
+    placeholder="user@example.com"
+    type="email"
+    error={emailError}
+  />
+  <Button type="submit">Submit</Button>
+</div>
+```
+
+### Product Card
+
+```tsx
+<div className="rounded-lg border p-4">
+  <Heading level={3}>Product Name</Heading>
+  <Text variant="body2">Product description</Text>
+  <div className="mt-4 flex items-center justify-between">
+    <PriceBadge price={50000} />
+    <Button icon="fa-cart-plus">Add to Cart</Button>
+  </div>
+</div>
+```
+
+### Rating Display
+
+```tsx
+<div>
+  <Heading level={4}>Reviews</Heading>
+  <Text variant="body1">⭐⭐⭐⭐⭐ 4.5/5</Text>
+  <Caption>Based on 128 reviews</Caption>
+</div>
+```
+
+---
+
+## 🧪 Testing Atoms
+
+### Props Validation
+
+```tsx
+// ✅ Valid
+<Button variant="primary" size="sm">Click</Button>
+
+// ❌ Invalid (TypeScript will catch)
+<Button variant="invalid">Click</Button>
+<Button size={10}>Click</Button>
+```
+
+### Accessibility
+
+All atoms include:
+
+- Semantic HTML
+- ARIA labels where appropriate
+- Keyboard navigation support
+- Focus visible states
+- Color contrast compliance

+
+## 🚀 Status
+
+Atoms are stable and in use across molecules and organisms. Molecules are
+implemented — see `components/COMPONENTS.md` for details. See
+`OPTIMIZATION_PLAN.md` for the full roadmap.
+
+---
+
+## 📝 Notes
+
+- All atoms use TypeScript for type safety
+- No business logic in atoms - they're purely presentational
+- Components are optimized for reusability
+- Styling uses Tailwind + CSS variables for consistency
+- Accessibility is built-in by default
+
