+
+These are some guidelines when using the SonarQube MCP server.
+
+# Important Tool Guidelines
+
+## Basic usage
+
+- **IMPORTANT**: After you finish generating or modifying any code files at the very end of the task, you MUST call the `analyze_file_list` tool (if it exists) to analyze the files you created or modified.
+- **IMPORTANT**: When starting a new task, you MUST disable automatic analysis with the `toggle_automatic_analysis` tool if it exists.
+- **IMPORTANT**: When you are done generating code at the very end of the task, you MUST re-enable automatic analysis with the `toggle_automatic_analysis` tool if it exists.
+
+## Project Keys
+
+- When a user mentions a project key, use `search_my_sonarqube_projects` first to find the exact project key
+- Don't guess project keys - always look them up
+
+## Code Language Detection
+
+- When analyzing code snippets, try to detect the programming language from the code syntax
+- If unclear, ask the user or make an educated guess based on syntax
+
+## Branch and Pull Request Context
+
+- Many operations support branch-specific analysis
+- If user mentions working on a feature branch, include the branch parameter
+
+## Code Issues and Violations
+
+- After fixing issues, do not attempt to verify them using `search_sonar_issues_in_projects`, as the server will not yet reflect the updates
+
+# Common Troubleshooting
+
+## Authentication Issues
+
+- SonarQube requires USER tokens (not project tokens)
+- When the error `SonarQube answered with Not authorized` occurs, verify the token type
+
+## Project Not Found
+
+- Use `search_my_sonarqube_projects` to find available projects
+- Verify project key spelling and format
+
+## Code Analysis Issues
+
+- Ensure programming language is correctly specified
+- Remind users that snippet analysis doesn't replace full project scans
+- Provide full file content for better analysis results

+# Copilot Instructions - NotificationKit-UI
+
+> **Purpose**: Development guidelines for NotificationKit-UI - reusable React notification UI components.
+
+---
+
+## 🎯 Package Overview
+
+**Package**: `@ciscode/ui-notification-kit`  
+**Type**: React Frontend Component Library  
+**Purpose**: Pre-built notification and alert UI components for React apps
+
+### This Package Provides:
+
+- Notification display components
+- Toast/alert components
+- Notification context providers
+- Notification state management hooks
+- TypeScript types for notification state
+- Vitest unit tests with 80%+ coverage
+- Changesets for version management
+- Husky + lint-staged for code quality
+
+---
+
+## 🏗️ Project Structure
+
+```
+src/
+  ├── components/           # React components
+  │   ├── Notification/
+  │   ├── Toast/
+  │   └── index.ts
+  ├── hooks/                # Custom hooks
+  │   ├── useNotification.ts
+  │   └── useToast.ts
+  ├── context/              # Context providers
+  │   └── NotificationProvider.tsx
+  ├── types/                # TypeScript types
+  │   └── notification.types.ts
+  └── index.ts              # Public exports
+```
+
+---
+
+## 📝 Naming Conventions
+
+**Components**: `PascalCase.tsx`
+
+- `Notification.tsx`
+- `Toast.tsx`
+- `Alert.tsx`
+
+**Hooks**: `camelCase.ts` with `use` prefix
+
+- `useNotification.ts`
+- `useToast.ts`
+
+**Types**: `kebab-case.ts`
+
+- `notification.types.ts`
+
+---
+
+## 🧪 Testing Standards
+
+### Coverage Target: 80%+
+
+**Unit Tests:**
+
+- ✅ All components
+- ✅ All custom hooks
+- ✅ Context logic
+- ✅ Type definitions
+
+**Component Tests:**
+
+- ✅ Rendering checks
+- ✅ User interactions
+- ✅ State changes
+
+**Test file location:**
+
+```
+Notification/
+  ├── Notification.tsx
+  └── Notification.test.tsx
+```
+
+---
+
+## 📚 Documentation
+
+### JSDoc Required For:
+
+- All exported components
+- All exported hooks
+- All exported types/interfaces
+- All public functions
+
+### Example:
+
+```typescript
+/**
+ * Displays a notification message
+ * @param message - The notification message
+ * @param type - Type of notification (success, error, warning, info)
+ * @returns Notification component
+ */
+export function Notification({ message, type }: Props): JSX.Element;
+```
+
+---
+
+## 🎨 Code Style
+
+- ESLint with TypeScript support (`--max-warnings=0`)
+- Prettier formatting
+- TypeScript strict mode
+- Functional components only
+- No `React.FC` - always explicit `JSX.Element` return type
+
+---
+
+## 🔄 Development Workflow
+
+### Branch Naming:
+
+```bash
+feature/NK-UI-123-add-notification
+bugfix/NK-UI-456-fix-toast-timing
+refactor/NK-UI-789-extract-styles
+```
+
+### Before Publishing:
+
+- [ ] All tests passing
+- [ ] Coverage >= 80%
+- [ ] ESLint checks pass
+- [ ] TypeScript strict mode passes
+- [ ] All public APIs documented
+- [ ] Changeset created
+- [ ] README updated
+
+---
+
+## 📦 Versioning
+
+**MAJOR** (x.0.0): Breaking API changes
+**MINOR** (0.x.0): New features (backward compatible)
+**PATCH** (0.0.x): Bug fixes and improvements
+
+Always create a changeset for user-facing changes using `npm run changeset`.
+
+---
+
+## 🔐 Security
+
+- Never expose sensitive data in notifications
+- Sanitize notification content
+- Validate all notification props
+- No `dangerouslySetInnerHTML` without approval
+
+---
+
+## 🚫 Restrictions
+
+**NEVER without approval:**
+
+- Breaking changes to component APIs
+- Removing exported components/hooks
+- Major dependency upgrades
+
+**CAN do autonomously:**
+
+- Bug fixes (non-breaking)
+- Internal refactoring
+- Adding new features (additive)
+- Test improvements
+
+---
+
+## 💬 Communication
+
+- Brief and direct
+- Reference component names when discussing changes
+- Flag breaking changes immediately
+- This package is consumed by multiple applications
+

+# Bugfix Instructions - UI Kit Module
+
+> **Last Updated**: February 2026
+
+---
+
+## 🔍 Bug Investigation Process
+
+### Phase 1: Reproduce
+
+**Before writing any code:**
+
+1. **Understand the issue** - Read bug report carefully
+2. **Reproduce locally** - Create minimal reproduction
+3. **Verify it's a bug** - Not expected behavior
+4. **Check browser compatibility** - Test across browsers
+
+**Create failing test FIRST:**
+
+```typescript
+describe('Bug: Button not disabled when loading', () => {
+  it('should disable button during loading', () => {
+    render(<Button isLoading>Click</Button>);
+    
+    // This SHOULD pass but currently FAILS
+    expect(screen.getByRole('button')).toBeDisabled();
+  });
+});
+```
+
+### Phase 2: Identify Root Cause
+
+**Investigation tools:**
+
+- **React DevTools** - Inspect component tree
+- **Console logs** - Debug state changes
+- **Debugger** - Breakpoints in code
+- **Browser DevTools** - Check DOM/styles
+
+```typescript
+// Debug component props/state
+useEffect(() => {
+  console.log('Props changed:', props);
+}, [props]);
+```
+
+### Phase 3: Understand Impact
+
+**Critical questions:**
+
+- Which browsers affected?
+- Does it break accessibility?
+- Is there a workaround?
+- Does it affect other components?
+
+---
+
+## 🐛 Common Bug Categories
+
+### 1. State Management Issues
+
+| Bug Type              | Symptoms               | Solution                    |
+| --------------------- | ---------------------- | --------------------------- |
+| **Stale closure**     | Old values in callback | Update dependencies         |
+| **Infinite loop**     | Component re-renders   | Fix useEffect dependencies  |
+| **Lost state**        | State resets unexpectedly| Check component key         |
+
+**Example fix:**
+
+```typescript
+// ❌ BUG - Stale closure
+const [count, setCount] = useState(0);
+
+useEffect(() => {
+  const timer = setInterval(() => {
+    setCount(count + 1); // ❌ Always uses initial count
+  }, 1000);
+  return () => clearInterval(timer);
+}, []); // Missing count dependency
+
+// ✅ FIX - Functional update
+useEffect(() => {
+  const timer = setInterval(() => {
+    setCount(prev => prev + 1); // ✅ Uses current count
+  }, 1000);
+  return () => clearInterval(timer);
+}, []);
+```
+
+### 2. useEffect Issues
+
+| Bug Type              | Symptoms              | Solution                    |
+| --------------------- | --------------------- | --------------------------- |
+| **Memory leak**       | Performance degrades  | Add cleanup function        |
+| **Missing cleanup**   | Side effects persist  | Return cleanup              |
+| **Wrong dependencies**| Unexpected behavior   | Fix dependency array        |
+
+**Example fix:**
+
+```typescript
+// ❌ BUG - No cleanup
+useEffect(() => {
+  const subscription = api.subscribe(handleData);
+}, []);
+
+// ✅ FIX - Cleanup on unmount
+useEffect(() => {
+  const subscription = api.subscribe(handleData);
+  return () => subscription.unsubscribe();
+}, []);
+```
+
+### 3. Event Handler Issues
+
+| Bug Type              | Symptoms              | Solution                    |
+| --------------------- | --------------------- | --------------------------- |
+| **Handler not called**| Click doesn't work    | Check event binding         |
+| **Multiple calls**    | Handler fires twice   | Remove duplicate listeners  |
+| **Wrong event**       | Unexpected behavior   | Use correct event type      |
+
+**Example fix:**
+
+```typescript
+// ❌ BUG - Handler called immediately
+<button onClick={handleClick()}> // ❌ Calls on render
+
+// ✅ FIX - Pass function reference
+<button onClick={handleClick}> // ✅ Calls on click
+<button onClick={() => handleClick(arg)}> // ✅ With arguments
+```
+
+### 4. Rendering Issues
+
+| Bug Type              | Symptoms              | Solution                    |
+| --------------------- | --------------------- | --------------------------- |
+| **Conditional render**| Component disappears  | Fix condition logic         |
+| **Key prop**          | Wrong items update    | Use stable unique keys      |
+| **Forced re-render**  | Performance issues    | Memoize expensive calcs     |
+
+**Example fix:**
+
+```typescript
+// ❌ BUG - Index as key
+{items.map((item, index) => (
+  <div key={index}>{item.name}</div>
+))}
+
+// ✅ FIX - Unique stable key
+{items.map(item => (
+  <div key={item.id}>{item.name}</div>
+))}
+```
+
+### 5. Accessibility Bugs
+
+| Bug Type              | Symptoms              | Solution                    |
+| --------------------- | --------------------- | --------------------------- |
+| **Missing ARIA**      | Screen reader issues  | Add ARIA attributes         |
+| **No keyboard nav**   | Can't use keyboard    | Add keyboard handlers       |
+| **Poor contrast**     | Hard to read          | Fix colors                  |
+
+**Example fix:**
+
+```typescript
+// ❌ BUG - Div as button (not accessible)
+<div onClick={handleClick}>
+  Submit
+</div>
+
+// ✅ FIX - Proper button element
+<button onClick={handleClick} aria-label="Submit form">
+  Submit
+</button>
+```
+
+---
+
+## 🔧 Fix Implementation Process
+
+### 1. Write Failing Test
+
+```typescript
+it('should fix the bug', async () => {
+  render(<Component />);
+  
+  await userEvent.click(screen.getByRole('button'));
+  
+  expect(screen.getByText(/expected/i)).toBeInTheDocument();
+});
+```
+
+### 2. Implement Fix
+
+```typescript
+// Fix the component
+export function Component() {
+  // Corrected implementation
+  return <div>Fixed!</div>;
+}
+```
+
+### 3. Verify Test Passes
+
+```bash
+npm test -- Component.test.tsx
+```
+
+### 4. Test in Browser
+
+```bash
+npm run dev
+# Manually test the fix
+```
+
+### 5. Update Documentation
+
+```typescript
+/**
+ * Component that was buggy
+ * 
+ * @fixed v1.2.3 - Fixed click handler issue
+ */
+export function Component(props: Props): JSX.Element
+```
+
+---
+
+## ⚠️ Common Gotchas
+
+### 1. Prop Mutation
+
+```typescript
+// ❌ Bug - Mutating props
+const sortedItems = props.items.sort(); // Mutates!
+
+// ✅ Fix - Create copy
+const sortedItems = [...props.items].sort();
+```
+
+### 2. Incorrect Comparison
+
+```typescript
+// ❌ Bug - Object comparison
+if (user === prevUser) { } // Always false (different references)
+
+// ✅ Fix - Compare values
+if (user.id === prevUser.id) { }
+```
+
+### 3. Missing Null Checks
+
+```typescript
+// ❌ Bug - No null check
+return user.profile.name; // Crashes if profile is null
+
+// ✅ Fix - Optional chaining
+return user?.profile?.name ?? 'Unknown';
+```
+
+---

+      aria-live={type === 'error' ? 'assertive' : 'polite'}
+      className={`notification notification-${type}`}
+    >
+      <p>{message}</p>
+      {actions && (
+        <div className="notification-actions">
+          {actions.map((action, i) => (
+            <button key={i} onClick={action.onClick}>
+              {action.label}
+            </button>
+          ))}
+        </div>
+      )}
+      <button
+        onClick={onClose}
+        aria-label="Close notification"
+        className="notification-close"
+      >
+        ×
+      </button>
+    </div>
+  );
+};
+
+Notification.displayName = 'Notification';
+```
+
+---
+
+## 📝 Props Standards
+
+### Notification Props Interface
+
+```typescript
+export interface NotificationProps {
+  /** Notification message content */
+  message: string | React.ReactNode;
+  /** Notification type/severity */
+  type?: 'info' | 'success' | 'warning' | 'error';
+  /** Auto-dismiss duration in ms (0 = no auto-dismiss) */
+  duration?: number;
+  /** Callback when notification is closed */
+  onClose: () => void;
+  /** Optional action buttons */
+  actions?: Array<{
+    label: string;
+    onClick: () => void;
+  }>;
+  /** Position on screen */
+  position?:
+    | 'top-right'
+    | 'top-left'
+    | 'bottom-right'
+    | 'bottom-left'
+    | 'top-center'
+    | 'bottom-center';
+}
+```
+
+---
+
+## ♿ Accessibility (A11y)
+
+### ARIA Live Regions
+
+```typescript
+// ✅ Good - Uses aria-live for screen readers
+<div
+  role="status"
+  aria-live={type === 'error' ? 'assertive' : 'polite'}
+  aria-atomic="true"
+>
+  {message}
+</div>
+
+// ❌ Bad - No screen reader support
+<div className="toast">{message}</div>
+```
+
+### Notification ARIA Attributes
+
+- ✅ `role="status"` or `role="alert"` for notifications
+- ✅ `aria-live="polite"` for info/success (non-critical)
+- ✅ `aria-live="assertive"` for error/warning (critical)
+- ✅ `aria-atomic="true"` to read entire message
+- ✅ Close button has `aria-label="Close notification"`
+
+### Keyboard Support
+
+```typescript
+// Dismiss on Escape key
+useEffect(() => {
+  const handleEscape = (e: KeyboardEvent) => {
+    if (e.key === 'Escape') {
+      onClose();
+    }
+  };
+
+  document.addEventListener('keydown', handleEscape);
+  return () => document.removeEventListener('keydown', handleEscape);
+}, [onClose]);
+```
+
+---
+
+## 🎨 Theming & Styling
+
+### Notification Types & Colors
+
+```typescript
+const notificationStyles = {
+  info: {
+    background: theme.colors.info,
+    color: theme.colors.infoText,
+    icon: 'ℹ️',
+  },
+  success: {
+    background: theme.colors.success,
+    color: theme.colors.successText,
+    icon: '✓',
+  },
+  warning: {
+    background: theme.colors.warning,
+    color: theme.colors.warningText,
+    icon: '⚠',
+  },
+  error: {
+    background: theme.colors.error,
+    color: theme.colors.errorText,
+    icon: '✕',
+  },
+};
+```
+
+### Animations
+
+```typescript
+// Entry animation
+@keyframes slideIn {
+  from {
+    transform: translateX(100%);
+    opacity: 0;
+  }
+  to {
+    transform: translateX(0);
+    opacity: 1;
+  }
+}
+
+// Exit animation
+@keyframes slideOut {
+  from {
+    transform: translateX(0);
+    opacity: 1;
+  }
+  to {
+    transform: translateX(100%);
+    opacity: 0;
+  }
+}
+```
+
+---
+
+## 🧪 Component Testing
+
+### Test Coverage Requirements
+
+```typescript
+describe('Notification', () => {
+  it('renders message', () => {
+    render(<Notification message="Test notification" onClose={jest.fn()} />);
+    expect(screen.getByText('Test notification')).toBeInTheDocument();
+  });
+
+  it('auto-dismisses after duration', async () => {
+    jest.useFakeTimers();
+    const onClose = jest.fn();
+
+    render(<Notification message="Test" duration={3000} onClose={onClose} />);
+
+    jest.advanceTimersByTime(3000);
+    expect(onClose).toHaveBeenCalled();
+
+    jest.useRealTimers();
+  });
+
+  it('calls onClose when close button clicked', async () => {
+    const onClose = jest.fn();
+    render(<Notification message="Test" onClose={onClose} />);
+
+    await userEvent.click(screen.getByLabelText('Close notification'));
+    expect(onClose).toHaveBeenCalled();
+  });
+
+  it('renders with correct ARIA attributes for errors', () => {
+    const { container } = render(
+      <Notification message="Error!" type="error" onClose={jest.fn()} />
+    );
+
+    expect(container.querySelector('[aria-live="assertive"]')).toBeInTheDocument();
+  });
+
+  it('renders action buttons', async () => {
+    const action = jest.fn();
+    render(
+      <Notification
+        message="Test"
+        onClose={jest.fn()}
+        actions={[{ label: 'Undo', onClick: action }]}
+      />
+    );
+
+    await userEvent.click(screen.getByRole('button', { name: 'Undo' }));
+    expect(action).toHaveBeenCalled();
+  });
+
+  it('does not auto-dismiss when duration is 0', () => {
+    jest.useFakeTimers();
+    const onClose = jest.fn();
+
+    render(<Notification message="Test" duration={0} onClose={onClose} />);
+
+    jest.advanceTimersByTime(10000);
+    expect(onClose).not.toHaveBeenCalled();
+
+    jest.useRealTimers();
+  });
+});
+```
+
+---
+
+## 🔄 State Management
+
+### Notification Queue Management
+
+```typescript
+interface NotificationState {
+  id: string;
+  message: string;
+  type: NotificationProps['type'];
+}
+
+const [notifications, setNotifications] = useState<NotificationState[]>([]);
+
+const addNotification = (notification: Omit<NotificationState, 'id'>) => {
+  const id = Date.now().toString();
+  setNotifications((prev) => [...prev, { ...notification, id }]);
+};
+
+const removeNotification = (id: string) => {
+  setNotifications((prev) => prev.filter((n) => n.id !== id));
+};
+```
+
+### Notification Context Provider
+
+```typescript
+import { createContext, useContext } from 'react';
+
+interface NotificationContextValue {
+  showNotification: (props: NotificationInput) => void;
+  hideNotification: (id: string) => void;
+}
+
+const NotificationContext = createContext<NotificationContextValue | null>(null);
+
+export const useNotification = () => {
+  const context = useContext(NotificationContext);
+  if (!context) {
+    throw new Error('useNotification must be used within NotificationProvider');
+  }
+  return context;
+};
+```
+
+---
+
+## 📦 Component Exports
+
+### Public API (index.ts)
+
+```typescript
+// Export components
+export { Notification } from './Notification';
+export { NotificationContainer } from './NotificationContainer';
+export { NotificationProvider, useNotification } from './NotificationContext';
+
+// Export types
+export type { NotificationProps } from './Notification.types';
+export type { NotificationPosition, NotificationType } from './types';
+```
+
+---
+
+## 🚫 Anti-Patterns to Avoid
+
+### ❌ Memory Leaks with Timers
+
+```typescript
+// Bad - Timer not cleaned up
+useEffect(() => {
+  setTimeout(onClose, duration);
+}, []);
+
+// Good - Timer cleaned up
+useEffect(() => {
+  const timer = setTimeout(onClose, duration);
+  return () => clearTimeout(timer);
+}, [duration, onClose]);
+```
+
+### ❌ No Maximum Notifications
+
+```typescript
+// Bad - Unlimited notifications can overflow screen
+const addNotification = (notif) => {
+  setNotifications((prev) => [...prev, notif]);
+};
+
+// Good - Limit max notifications shown
+const MAX_NOTIFICATIONS = 5;
+const addNotification = (notif) => {
+  setNotifications((prev) => [...prev.slice(-MAX_NOTIFICATIONS + 1), notif]);
+};
+```
+
+### ❌ Blocking UI with Notifications
+
+```typescript
+// Bad - Notifications block content
+<div style={{ position: 'absolute', top: 0, left: 0, right: 0 }}>
+
+// Good - Notifications overlay in corner
+<div style={{ position: 'fixed', top: 20, right: 20, zIndex: 9999 }}>
+```
+
+---

+
+---
+
+## 🧪 Testing - Component Library Standards
+
+### Coverage Target: 80%+
+
+**Unit Tests:**
+
+- ✅ All custom hooks
+- ✅ Utilities and helpers
+- ✅ Context logic
+
+**Component Tests:**
+
+- ✅ All components with user interactions
+- ✅ Notification display logic
+- ✅ Error state handling
+- ✅ Auto-dismiss functionality
+
+**Skip:**
+
+- ❌ Purely presentational components (no logic)
+
+**Test location:**
+
+```
+Toast/
+  ├── Toast.tsx
+  └── Toast.test.tsx  ← Same directory
+```
+
+---
+
+## 📚 Documentation Standards
+
+### JSDoc for Hooks:
+
+```typescript
+/**
+ * Hook for managing notification state
+ * @returns Notification methods and state
+ * @example
+ * ```tsx
+ * const { notify, dismiss, notifications } = useNotifications();
+ * 
+ * const showSuccess = () => {
+ *   notify({ type: 'success', message: 'Action completed!' });
+ * };
+ * ```
+ */
+export function useNotifications(): UseNotificationsReturn;
+```
+
+### Component Documentation:
+
+```typescript
+export interface ToastProps {
+  /** Toast message content */
+  message: string;
+  /** Toast type (success, error, warning, info) */
+  type?: 'success' | 'error' | 'warning' | 'info';
+  /** Auto-dismiss duration in ms (0 = no auto-dismiss) */
+  duration?: number;
+  /** Callback when toast is dismissed */
+  onDismiss?: () => void;
+}
+
+/**
+ * Toast notification component
+ * 
+ * @example
+ * ```tsx
+ * <Toast
+ *   type="success"
+ *   message="Operation successful!"
+ *   duration={3000}
+ * />
+ * ```
+ */
+export function Toast(props: ToastProps): JSX.Element;
+```
+
+---
+
+## 🚀 Module Development Principles
+
+### 1. Headless & Customizable
+
+**Unstyled by default:**
+
+```typescript
+// Components accept className prop
+<Toast className="my-custom-styles" message="Hello!" />
+```
+
+### 2. Accessibility First
+
+**ARIA support:**
+
+```tsx
+<div role="alert" aria-live="polite">
+  {message}
+</div>
+```
+
+### 3. TypeScript Strict Mode
+
+```typescript
+// All exports fully typed
+export type NotificationType = 'success' | 'error' | 'warning' | 'info';
+```
+
+---
+
+## 🛠️ Development Workflow
+
+### Creating New Components:
+
+1. **Create component folder**
+   ```
+   mkdir -p src/components/MyComponent
+   cd src/components/MyComponent
+   ```
+
+2. **Create files**
+   - `MyComponent.tsx` - Component implementation
+   - `MyComponent.test.tsx` - Component tests
+   - `index.ts` - Export
+
+3. **Export from main index**
+   ```typescript
+   // src/index.ts
+   export { MyComponent } from './components/MyComponent';
+   ```
+
+### Testing Commands:
+
+```bash
+npm test                    # Run all tests
+npm run test:watch          # Watch mode
+npm run test:coverage       # Coverage report
+```
+
+### Build Commands:
+
+```bash
+npm run build              # Build for production
+npm run dev                # Development mode
+```
+
+---
+
+## ⚠️ Common Gotchas
+
+### 1. Auto-dismiss Timers
+
+```typescript
+// ✅ Clean up timers
+useEffect(() => {
+  const timer = setTimeout(() => dismiss(), duration);
+  return () => clearTimeout(timer);
+}, [duration]);
+```
+
+### 2. Notification Queue Management
+
+```typescript
+// ✅ Limit queue size
+const MAX_NOTIFICATIONS = 5;
+const addNotification = (notif) => {
+  setNotifications(prev => [...prev.slice(-MAX_NOTIFICATIONS + 1), notif]);
+};
+```
+
+### 3. Z-index Management
+
+```typescript
+// Define consistent z-index scale
+const NOTIFICATION_Z_INDEX = 9999;
+```
+
+---
+
+## 📦 Dependencies
+
+**Keep minimal:**
+
+- ✅ React 18+
+- ✅ TypeScript 5+
+- ❌ Avoid heavy animation libraries
+- ❌ Avoid CSS-in-JS unless necessary
+
+---
+
+## 📋 Code Review Checklist
+
+Before submitting PR:
+
+- [ ] All components have tests (80%+ coverage)
+- [ ] JSDoc comments on all exports
+- [ ] Props interface documented
+- [ ] Accessibility attributes added
+- [ ] TypeScript strict mode passes
+- [ ] No console.log statements
+- [ ] Updated exports in main index.ts
+
+---
+
+## 🔗 Integration Guidelines
+
+**With backend NotificationKit:**
+
+```typescript
+import { useNotifications } from '@ciscode/ui-notification-kit';
+import { notificationSocket } from '@ciscode/notification-kit';
+
+// Listen to backend events
+notificationSocket.on('notification', (data) => {
+  notify({ type: data.type, message: data.message });
+});
+```

+
+## ➕ Adding New Component
+
+### Example: Badge Component
+
+**Step 1: Design Props Interface**
+
+```typescript
+// src/components/Badge/Badge.tsx
+export interface BadgeProps {
+  /** Badge content */
+  children: React.ReactNode;
+  /** Visual variant */
+  variant?: 'default' | 'success' | 'warning' | 'error';
+  /** Size variant */
+  size?: 'sm' | 'md' | 'lg';
+  /** Custom CSS class */
+  className?: string;
+  /** Accessibility label */
+  'aria-label'?: string;
+}
+```
+
+**Step 2: Implement Component**
+
+```typescript
+/**
+ * Badge component for displaying status or counts
+ * 
+ * @example
+ * ```tsx
+ * <Badge variant="success">Active</Badge>
+ * <Badge variant="error">3</Badge>
+ * ```
+ */
+export function Badge({
+  children,
+  variant = 'default',
+  size = 'md',
+  className,
+  'aria-label': ariaLabel,
+}: BadgeProps): JSX.Element {
+  const variantClasses = {
+    default: 'bg-gray-100 text-gray-800',
+    success: 'bg-green-100 text-green-800',
+    warning: 'bg-yellow-100 text-yellow-800',
+    error: 'bg-red-100 text-red-800',
+  };
+
+  const sizeClasses = {
+    sm: 'text-xs px-2 py-0.5',
+    md: 'text-sm px-2.5 py-1',
+    lg: 'text-base px-3 py-1.5',
+  };
+
+  return (
+    <span
+      className={`
+        inline-flex items-center rounded-full font-medium
+        ${variantClasses[variant]}
+        ${sizeClasses[size]}
+        ${className || ''}
+      `}
+      aria-label={ariaLabel}
+      role="status"
+    >
+      {children}
+    </span>
+  );
+}
+```
+
+**Step 3: Write Tests**
+
+```typescript
+// src/components/Badge/Badge.test.tsx
+import { render, screen } from '@testing-library/react';
+import { Badge } from './Badge';
+
+describe('Badge', () => {
+  it('should render with text', () => {
+    render(<Badge>Active</Badge>);
+    
+    expect(screen.getByRole('status')).toHaveTextContent('Active');
+  });
+
+  it('should apply variant styles', () => {
+    render(<Badge variant="success">Success</Badge>);
+    
+    const badge = screen.getByRole('status');
+    expect(badge.className).toMatch(/bg-green-100/);
+  });
+
+  it('should apply size classes', () => {
+    render(<Badge size="lg">Large</Badge>);
+    
+    const badge = screen.getByRole('status');
+    expect(badge.className).toMatch(/text-base/);
+  });
+
+  it('should accept custom className', () => {
+    render(<Badge className="custom-class">Test</Badge>);
+    
+    expect(screen.getByRole('status')).toHaveClass('custom-class');
+  });
+
+  it('should have no accessibility violations', async () => {
+    const { container } = render(<Badge>Test</Badge>);
+    
+    const results = await axe(container);
+    expect(results).toHaveNoViolations();
+  });
+});
+```
+
+**Step 4: Export Component**
+
+```typescript
+// src/components/Badge/index.ts
+export { Badge } from './Badge';
+export type { BadgeProps } from './Badge';
+
+// src/index.ts
+export { Badge } from './components/Badge';
+export type { BadgeProps } from './components/Badge';
+```
+
+---
+
+## 🪝 Adding New Hook
+
+### Example: useLocalStorage Hook
+
+**Step 1: Implement Hook**
+
+```typescript
+// src/hooks/use-local-storage.ts
+import { useState, useEffect } from 'react';
+
+/**
+ * Hook for syncing state with localStorage
+ * 
+ * @param key - localStorage key
+ * @param initialValue - Default value
+ * @returns Tuple of [value, setValue]
+ * 
+ * @example
+ * ```tsx
+ * const [name, setName] = useLocalStorage<string>('name', 'Guest');
+ * ```
+ */
+export function useLocalStorage<T>(
+  key: string,
+  initialValue: T
+): [T, (value: T) => void] {
+  const [storedValue, setStoredValue] = useState<T>(() => {
+    try {
+      const item = window.localStorage.getItem(key);
+      return item ? JSON.parse(item) : initialValue;
+    } catch (error) {
+      console.warn(`Error reading localStorage key "${key}":`, error);
+      return initialValue;
+    }
+  });
+
+  const setValue = (value: T) => {
+    try {
+      setStoredValue(value);
+      window.localStorage.setItem(key, JSON.stringify(value));
+    } catch (error) {
+      console.error(`Error setting localStorage key "${key}":`, error);
+    }
+  };
+
+  return [storedValue, setValue];
+}
+```
+
+**Step 2: Write Tests**
+
+```typescript
+// src/hooks/use-local-storage.test.ts
+import { renderHook, act } from '@testing-library/react';
+import { useLocalStorage } from './use-local-storage';
+
+describe('useLocalStorage', () => {
+  beforeEach(() => {
+    localStorage.clear();
+  });
+
+  it('should initialize with default value', () => {
+    const { result } = renderHook(() =>
+      useLocalStorage('test', 'default')
+    );
+    
+    expect(result.current[0]).toBe('default');
+  });
+
+  it('should update localStorage when value changes', () => {
+    const { result } = renderHook(() =>
+      useLocalStorage('test', 'initial')
+    );
+    
+    act(() => {
+      result.current[1]('updated');

+    const { result } = renderHook(() =>
+      useLocalStorage('test', 'default')
+    );
+    
+    expect(result.current[0]).toBe('existing');
+  });
+});
+```

+
+## 🎨 Styling Guidelines
+
+### Headless Components
+
+```typescript
+// ✅ Accept className prop
+interface MyComponentProps {
+  className?: string;
+}
+
+// ✅ Allow style customization
+<div className={className} style={style}>
+```
+
+### CSS Variables
+
+```typescript
+// ✅ Support theming via CSS vars
+<button style={{ '--primary-color': color }}>
+```
+
+---
+
+## ♿ Accessibility Requirements
+
+### ARIA Attributes
+
+```typescript
+<button
+  aria-label="Close dialog"
+  aria-pressed={isPressed}
+  role="button"
+>
+```
+
+### Keyboard Navigation
+
+```typescript
+<div
+  role="button"
+  tabIndex={0}
+  onKeyDown={(e) => {
+    if (e.key === 'Enter' || e.key === ' ') {
+      handleClick();
+    }
+  }}
+>
+```
+
+---
+
+## 📦 Exporting Features
+
+**Update exports:**
+
+```typescript
+// src/index.ts
+export { Badge } from './components/Badge';
+export { useLocalStorage } from './hooks/use-local-storage';
+export type { BadgeProps } from './components/Badge';
+```
+
+---
+
+## ⚠️ Breaking Changes
+
+### Migration Guide Example
+
+```markdown
+## Breaking Changes in v2.0.0
+
+### Button Component
+
+**Before (v1.x):**
+```tsx
+<Button type="primary">Click</Button>
+```
+
+**After (v2.0):**
+```tsx
+<Button variant="primary">Click</Button>
+```
+
+Rename `type` prop to `variant` for consistency.
+```

+
+## 📝 Coding Standards
+
+### Component Patterns
+
+```typescript
+// ✅ Functional components with TypeScript
+interface MyComponentProps {
+  /** Component title */
+  title: string;
+  /** Optional callback */
+  onAction?: () => void;
+}
+
+export function MyComponent({ title, onAction }: MyComponentProps) {
+  return <div onClick={onAction}>{title}</div>;
+}
+
+// ❌ Class components
+class MyComponent extends React.Component { }
+```
+
+### Prop Naming
+
+```typescript
+// ✅ Descriptive, semantic names
+interface ButtonProps {
+  onClick: () => void;
+  isDisabled?: boolean;
+  variant?: 'primary' | 'secondary';
+}
+
+// ❌ Generic, unclear names
+interface ButtonProps {
+  handler: any;
+  disabled: boolean;
+  type: string;
+}
+```
+
+### TypeScript Strictness
+
+```typescript
+// ✅ Explicit types
+const [count, setCount] = useState<number>(0);
+
+// ❌ Implicit any
+const [count, setCount] = useState();
+```
+
+---
+
+## 🎨 Styling Philosophy
+
+### Headless by Default
+
+Components should accept `className` for styling:
+
+```typescript
+interface ComponentProps {
+  className?: string;
+}
+
+export function Component({ className }: ComponentProps) {
+  return <div className={className}>Content</div>;
+}
+```
+
+### CSS Variables for Theming
+
+```typescript
+// Support CSS custom properties
+<div style={{ '--primary-color': color }}>
+```
+
+---
+
+## ♿ Accessibility Requirements
+
+### ARIA Attributes
+
+```typescript
+// ✅ Include ARIA for screen readers
+<button aria-label="Close dialog" onClick={onClose}>
+  ×
+</button>
+
+// ❌ Missing accessibility
+<div onClick={onClose}>×</div>
+```
+
+### Keyboard Navigation
+
+```typescript
+// ✅ Handle keyboard events
+<div
+  role="button"
+  tabIndex={0}
+  onClick={handleClick}
+  onKeyDown={(e) => e.key === 'Enter' && handleClick()}
+>
+```
+
+---
+
+## 🧪 Testing Philosophy
+
+- **Target**: 80%+ code coverage
+- **Test user interactions**, not implementation
+- **Mock external dependencies**
+- **Test accessibility** with jest-axe
+
+---
+
+## 📚 Documentation Requirements
+
+### Component JSDoc
+
+```typescript
+/**
+ * Button component with multiple variants
+ * 
+ * @example
+ * ```tsx
+ * <Button variant="primary" onClick={() => console.log('Clicked')}>
+ *   Click Me
+ * </Button>
+ * ```
+ */
+export function Button(props: ButtonProps): JSX.Element
+```
+
+### Props Interface Documentation
+
+```typescript
+export interface ButtonProps {
+  /** Button text content */
+  children: React.ReactNode;
+  /** Click event handler */
+  onClick?: () => void;
+  /** Visual variant */
+  variant?: 'primary' | 'secondary' | 'danger';
+  /** Disable button interaction */
+  disabled?: boolean;
+}
+```
+
+---
+
+## 🚀 Development Workflow
+
+1. **Design** - Plan component API and props
+2. **Implement** - Write component following standards
+3. **Test** - Unit tests with React Testing Library
+4. **Document** - JSDoc and examples
+5. **Release** - Semantic versioning
+
+---
+
+## ⚠️ Common Gotchas
+
+### 1. Event Handlers
+
+```typescript
+// ✅ Use optional callbacks
+onClick?.();
+
+// ❌ Call without checking
+onClick();
+```
+
+### 2. useEffect Cleanup
+
+```typescript
+// ✅ Clean up side effects
+useEffect(() => {
+  const timer = setTimeout(() => {}, 1000);
+  return () => clearTimeout(timer);
+}, []);
+
+// ❌ Missing cleanup
+useEffect(() => {
+  setTimeout(() => {}, 1000);
+}, []);
+```
+
+### 3. Key Props in Lists
+
+```typescript
+// ✅ Unique, stable keys
+{items.map(item => <div key={item.id}>{item.name}</div>)}
+
+// ❌ Index as key
+{items.map((item, i) => <div key={i}>{item.name}</div>)}
+```
+
+---
+
+## 📦 Build Configuration
+
+Ensure proper build setup:
+
+```json
+{
+  "main": "dist/index.js",
+  "module": "dist/index.mjs",
+  "types": "dist/index.d.ts",
+  "files": ["dist"]
+}
+```
+
+---
+
+## 🔍 Testing Commands
+
+```bash
+npm test                    # Run tests
+npm run test:watch          # Watch mode
+npm run test:coverage       # Coverage report
+```

+
+These are some guidelines when using the SonarQube MCP server.
+
+# Important Tool Guidelines
+
+## Basic usage
+
+- **IMPORTANT**: After you finish generating or modifying any code files at the very end of the task, you MUST call the `analyze_file_list` tool (if it exists) to analyze the files you created or modified.
+- **IMPORTANT**: When starting a new task, you MUST disable automatic analysis with the `toggle_automatic_analysis` tool if it exists.
+- **IMPORTANT**: When you are done generating code at the very end of the task, you MUST re-enable automatic analysis with the `toggle_automatic_analysis` tool if it exists.
+
+## Project Keys
+
+- When a user mentions a project key, use `search_my_sonarqube_projects` first to find the exact project key
+- Don't guess project keys - always look them up
+
+## Code Language Detection
+
+- When analyzing code snippets, try to detect the programming language from the code syntax
+- If unclear, ask the user or make an educated guess based on syntax
+
+## Branch and Pull Request Context
+
+- Many operations support branch-specific analysis
+- If user mentions working on a feature branch, include the branch parameter
+
+## Code Issues and Violations
+
+- After fixing issues, do not attempt to verify them using `search_sonar_issues_in_projects`, as the server will not yet reflect the updates
+
+# Common Troubleshooting
+
+## Authentication Issues
+
+- SonarQube requires USER tokens (not project tokens)
+- When the error `SonarQube answered with Not authorized` occurs, verify the token type
+
+## Project Not Found
+
+- Use `search_my_sonarqube_projects` to find available projects
+- Verify project key spelling and format
+
+## Code Analysis Issues
+
+- Ensure programming language is correctly specified
+- Remind users that snippet analysis doesn't replace full project scans
+- Provide full file content for better analysis results

+
+---
+
+## 🎯 Testing Philosophy
+
+### Test User Behavior, Not Implementation
+
+**✅ Test what users see and do:**
+
+```typescript
+it('should show error message when form is invalid', async () => {
+  render(<LoginForm />);
+  
+  const submitButton = screen.getByRole('button', { name: /submit/i });
+  await userEvent.click(submitButton);
+  
+  expect(screen.getByText(/email is required/i)).toBeInTheDocument();
+});
+```
+
+**❌ Don't test implementation details:**
+
+```typescript
+it('should update state when input changes', () => {
+  const { rerender } = render(<Component />);
+  // Testing internal state = implementation detail
+  expect(component.state.value).toBe('test');
+});
+```
+
+---
+
+## 📊 Coverage Targets
+
+| Layer           | Minimum Coverage | Priority    |
+| --------------- | ---------------- | ----------- |
+| **Hooks**       | 90%+             | 🔴 Critical |
+| **Components**  | 80%+             | 🟡 High     |
+| **Utils**       | 85%+             | 🟡 High     |
+| **Context**     | 90%+             | 🔴 Critical |
+
+**Overall Target**: 80%+
+
+---
+
+## 📁 Test File Organization
+
+### File Placement
+
+Tests live next to components:
+
+```
+src/components/Button/
+  ├── Button.tsx
+  └── Button.test.tsx  ← Same directory
+```
+
+### Naming Convention
+
+| Code File      | Test File       |
+| -------------- | --------------- |
+| `Button.tsx`   | `Button.test.tsx` |
+| `use-auth.ts`  | `use-auth.test.ts` |
+
+---
+
+## 🎭 Test Structure
+
+### Component Test Template
+
+```typescript
+import { describe, it, expect, beforeEach, vi } from 'vitest';
+import { render, screen } from '@testing-library/react';
+import userEvent from '@testing-library/user-event';
+import { Button } from './Button';
+
+describe('Button', () => {
+  it('should render with text', () => {
+    render(<Button>Click me</Button>);
+    
+    expect(screen.getByRole('button', { name: /click me/i }))
+      .toBeInTheDocument();
+  });
+
+  it('should call onClick when clicked', async () => {
+    const handleClick = vi.fn();
+    render(<Button onClick={handleClick}>Click</Button>);
+    
+    await userEvent.click(screen.getByRole('button'));
+    
+    expect(handleClick).toHaveBeenCalledTimes(1);
+  });
+
+  it('should be disabled when disabled prop is true', () => {
+    render(<Button disabled>Click</Button>);
+    
+    expect(screen.getByRole('button')).toBeDisabled();
+  });
+});
+```
+
+### Hook Test Template
+
+```typescript
+import { renderHook, act } from '@testing-library/react';
+import { useCounter } from './use-counter';
+
+describe('useCounter', () => {
+  it('should initialize with default value', () => {
+    const { result } = renderHook(() => useCounter());
+    
+    expect(result.current.count).toBe(0);
+  });
+
+  it('should increment count', () => {
+    const { result } = renderHook(() => useCounter());
+    
+    act(() => {
+      result.current.increment();
+    });
+    
+    expect(result.current.count).toBe(1);
+  });
+
+  it('should decrement count', () => {
+    const { result } = renderHook(() => useCounter(5));
+    
+    act(() => {
+      result.current.decrement();
+    });
+    
+    expect(result.current.count).toBe(4);
+  });
+});
+```
+
+---
+
+## 🎭 Testing Patterns
+
+### Querying Elements
+
+**Prefer accessible queries:**
+
+```typescript
+// ✅ BEST - By role (accessible)
+screen.getByRole('button', { name: /submit/i })
+screen.getByRole('textbox', { name: /email/i })
+
+// ✅ GOOD - By label text
+screen.getByLabelText(/email/i)
+
+// ⚠️ OK - By test ID (last resort)
+screen.getByTestId('submit-button')
+
+// ❌ BAD - By class or internal details
+container.querySelector('.button-class')
+```
+
+### User Interactions
+
+**Use userEvent over fireEvent:**
+
+```typescript
+import userEvent from '@testing-library/user-event';
+
+// ✅ GOOD - userEvent (realistic)
+await userEvent.click(button);
+await userEvent.type(input, 'test@example.com');
+
+// ❌ BAD - fireEvent (synthetic)
+fireEvent.click(button);
+fireEvent.change(input, { target: { value: 'test' } });
+```
+
+### Async Testing
+
+```typescript
+// ✅ Wait for element to appear
+const message = await screen.findByText(/success/i);
+
+// ✅ Wait for element to disappear
+await waitForElementToBeRemoved(() => screen.queryByText(/loading/i));
+
+// ✅ Wait for assertion
+await waitFor(() => {
+  expect(screen.getByText(/loaded/i)).toBeInTheDocument();
+});
+```
+
+---
+
+## 🧪 Test Categories
+
+### 1. Component Tests
+
+**What to test:**
+
+- ✅ Rendering with different props
+- ✅ User interactions (click, type, etc.)
+- ✅ Conditional rendering
+- ✅ Error states
+
+**Example:**
+
+```typescript
+describe('LoginForm', () => {
+  it('should display error for empty email', async () => {
+    render(<LoginForm />);
+    
+    const submitBtn = screen.getByRole('button', { name: /login/i });
+    await userEvent.click(submitBtn);
+    
+    expect(screen.getByText(/email is required/i)).toBeInTheDocument();
+  });
+
+  it('should call onSuccess when login succeeds', async () => {
+    const onSuccess = vi.fn();
+    render(<LoginForm onSuccess={onSuccess} />);
+    
+    await userEvent.type(
+      screen.getByLabelText(/email/i),
+      'test@example.com'
+    );
+    await userEvent.type(
+      screen.getByLabelText(/password/i),
+      'password123'
+    );
+    await userEvent.click(screen.getByRole('button', { name: /login/i }));
+    
+    await waitFor(() => {
+      expect(onSuccess).toHaveBeenCalledWith(expect.objectContaining({
+        email: 'test@example.com'
+      }));
+    });
+  });
+});
+```
+
+### 2. Hook Tests
+
+**What to test:**
+
+- ✅ Initial state
+- ✅ State updates
+- ✅ Side effects
+- ✅ Cleanup
+
+**Example:**
+
+```typescript
+describe('useAuth', () => {
+  it('should login user', async () => {
+    const { result } = renderHook(() => useAuth());
+    
+    await act(async () => {
+      await result.current.login('test@example.com', 'password');
+    });
+    
+    expect(result.current.user).toEqual({
+      email: 'test@example.com'
+    });
+    expect(result.current.isAuthenticated).toBe(true);
+  });
+
+  it('should cleanup on unmount', () => {
+    const cleanup = vi.fn();
+    vi.spyOn(global, 'removeEventListener').mockImplementation(cleanup);
+    
+    const { unmount } = renderHook(() => useAuth());
+    unmount();
+    
+    expect(cleanup).toHaveBeenCalled();
+  });
+});
+```
+
+### 3. Accessibility Tests
+
+**Use jest-axe:**
+
+```typescript
+import { axe, toHaveNoViolations } from 'jest-axe';
+
+expect.extend(toHaveNoViolations);
+
+it('should have no accessibility violations', async () => {
+  const { container } = render(<LoginForm />);
+  
+  const results = await axe(container);
+  expect(results).toHaveNoViolations();
+});
+```
+
+---
+
+## 🎨 Mocking
+
+### Mocking Context
+
+```typescript
+const mockAuthContext = {
+  user: { id: '1', email: 'test@example.com' },
+  login: vi.fn(),
+  logout: vi.fn(),
+  isAuthenticated: true,
+};
+
+const wrapper = ({ children }) => (
+  <AuthContext.Provider value={mockAuthContext}>
+    {children}
+  </AuthContext.Provider>
+);
+
+render(<Component />, { wrapper });
+```
+
+### Mocking API Calls
+
+```typescript
+import { vi } from 'vitest';
+
+global.fetch = vi.fn(() =>
+  Promise.resolve({
+    ok: true,
+    json: () => Promise.resolve({ data: 'mocked' }),
+  })
+);
+```
+
+---
+
+## 🧪 Test Commands
+
+```bash
+# Run all tests
+npm test
+
+# Watch mode
+npm run test:watch
+
+# Coverage report
+npm run test:coverage
+
+# UI mode (Vitest)
+npm run test:ui
+```
+
+---
+
+## ⚠️ Common Mistakes
+
+### 1. Not Waiting for Async Updates
+
+```typescript
+// ❌ BAD - Missing await
+it('test', () => {
+  userEvent.click(button);
+  expect(screen.getByText(/success/i)).toBeInTheDocument();
+});
+
+// ✅ GOOD - Properly awaited
+it('test', async () => {
+  await userEvent.click(button);
+  expect(await screen.findByText(/success/i)).toBeInTheDocument();
+});
+```
+
+### 2. Testing Implementation Details
+
+```typescript
+// ❌ BAD - Testing internal state
+expect(component.state.isOpen).toBe(true);
+
+// ✅ GOOD - Testing visible behavior
+expect(screen.getByRole('dialog')).toBeVisible();
+```
+
+### 3. Not Cleaning Up
+
+```typescript
+// ✅ Always use cleanup
+import { cleanup } from '@testing-library/react';
+
+afterEach(() => {
+  cleanup();
+  vi.clearAllMocks();
+});
+```
+
+---
+

-# React TypeScript DeveloperKit (Template)
+# NotificationKit-UI
 
-Template repository for building reusable React TypeScript **npm libraries**
-(components + hooks + utilities).
+NotificationKit-UI is a React + TypeScript notification library with multiple variants, configurable behavior, accessibility support, and route-aware clearing.
 
-## What you get
+## Features
 
-- ESM + CJS + Types build (tsup)
-- Vitest testing
-- ESLint + Prettier (flat config)
-- Changesets (manual release flow, no automation PR)
-- Husky (pre-commit + pre-push)
-- Enforced public API via `src/index.ts`
-- Dependency-free styling (Tailwind-compatible by convention only)
-- `react` and `react-dom` as peerDependencies
+- Notification types: `success`, `error`, `warning`, `info`, `loading`, `default`
+- Positions: `top-left`, `top-center`, `top-right`, `center`, `bottom-left`, `bottom-center`, `bottom-right`
+- Configurable animation: `slide`, `fade`, `scale`
+- Auto-dismiss with per-notification override
+- Optional action buttons
+- Optional close button
+- Pause on hover and pause on focus
+- Queue limit (FIFO) with history support
+- Route-aware clearing with `clearOnNavigate`
+- Dark mode compatible styles
+- RTL-ready Tailwind setup
+- Accessibility: ARIA roles, live-region announcements, keyboard escape-to-dismiss
 
-## Package structure
+## Installation
 
-- `src/components` – reusable UI components
-- `src/hooks` – reusable React hooks
-- `src/utils` – framework-agnostic utilities
-- `src/index.ts` – **only public API** (no deep imports allowed)
+```bash
+npm install @ciscode/ui-notification-kit
+```
 
-Anything not exported from `src/index.ts` is considered private.
+Also ensure host app peer dependencies are installed:
 
-## Scripts
+- `react`
+- `react-dom`
 
-- `npm run build` – build to `dist/` (tsup)
-- `npm test` – run tests (vitest)
-- `npm run typecheck` – TypeScript typecheck
-- `npm run lint` – ESLint
-- `npm run format` / `npm run format:write` – Prettier
-- `npx changeset` – create a changeset
+## Styling
 
-## Release flow (summary)
+Import package styles once in your app entry file:
 
-- Work on a `feature` branch from `develop`
-- Merge to `develop`
-- Add a changeset for user-facing changes: `npx changeset`
-- Promote `develop` → `master`
-- Tag `vX.Y.Z` to publish (npm OIDC)
+```ts
+import '@ciscode/ui-notification-kit/style.css';
+```
 
-This repository is a **template**. Teams should clone it and focus only on
-library logic, not tooling or release mechanics.
+## Quick Start
+
+```tsx
+import React from 'react';
+import { NotificationProvider, useNotification } from '@ciscode/ui-notification-kit';
+import '@ciscode/ui-notification-kit/style.css';
+
+function Demo() {
+  const { success, error, loading, update } = useNotification();
+
+  const runTask = async () => {
+    const pending = loading({
+      title: 'Please wait',
+      message: 'Processing request...',
+      autoDismiss: false,
+    });
+
+    try {
+      await new Promise((resolve) => setTimeout(resolve, 1200));
+      update({
+        id: pending.id,
+        type: 'success',
+        title: 'Done',
+        message: 'Operation completed',
+        autoDismiss: true,
+      });
+    } catch {
+      error({ title: 'Failed', message: 'Something went wrong' });
+    }
+  };
+
+  return <button onClick={runTask}>Run Task</button>;
+}
+
+export default function App() {
+  return (
+    <NotificationProvider>
+      <Demo />
+    </NotificationProvider>
+  );
+}
+```
+
+## Provider API
+
+`NotificationProvider` props:
+
+- `config?: NotificationProviderConfig`
+- `navigationKey?: string | number`
+
+`navigationKey` can be tied to router location changes. When it changes, notifications with `clearOnNavigate: true` are removed while others remain visible.
+
+### Example with React Router
+
+```tsx
+import { useLocation } from 'react-router-dom';
+import { NotificationProvider } from '@ciscode/ui-notification-kit';
+
+function RootLayout({ children }: { children: React.ReactNode }) {
+  const location = useLocation();
+
+  return <NotificationProvider navigationKey={location.key}>{children}</NotificationProvider>;
+}
+```
+
+## Hook API
+
+`useNotification()` returns:
+
+- `state`
+- `config`
+- `notify(config)`
+- `success(config)`
+- `error(config)`
+- `warning(config)`
+- `info(config)`
+- `loading(config)`
+- `defaultNotification(config)`
+- `update({ id, ...patch })`
+- `dismiss(id)`
+- `clearAll()`
+- `restore(id)`
+
+## Notification Config
+
+Main fields you can pass to `notify` and typed helper methods:
+
+- `title?: string`
+- `message?: string`
+- `body?: ReactNode`
+- `type?: NotificationType`
+- `position?: NotificationPosition`
+- `animation?: { type: 'slide' | 'fade' | 'scale'; durationMs: number }`
+- `autoDismiss?: boolean`
+- `durationMs?: number`
+- `pauseOnHover?: boolean`
+- `pauseOnFocus?: boolean`
+- `closeButton?: boolean`
+- `clearOnNavigate?: boolean`
+- `actions?: { label: string; onClick: () => void }[]`
+- `icon?: ReactNode | null`
+- `onClick?: () => void`
+- `ariaRole?: 'status' | 'alert'`
+
+## Provider Defaults
+
+`NotificationProviderConfig` supports:
+
+- `maxVisible` (default: `5`)
+- `defaultType` (default: `default`)
+- `defaultPosition` (default: `top-right`)
+- `defaultAnimation` (default: `{ type: 'slide', durationMs: 300 }`)
+- `defaultAutoDismiss` (default: `true`)
+- `defaultDurationMs` (default: `4000`)
+- `defaultPauseOnHover` (default: `true`)
+- `defaultPauseOnFocus` (default: `true`)
+- `defaultCloseButton` (default: `true`)
+- `defaultClearOnNavigate` (default: `false`)
+- `defaultAriaRole` (default: `status`)
+- `defaultIcon` (default: `null`)
+- `historyLimit` (default: `20`)
+
+## Accessibility Notes
+
+- Uses ARIA role per notification (`status` or `alert`)
+- Adds live-region announcements for screen readers
+- Supports keyboard escape to dismiss
+- Supports pause-on-focus for better readability
+
+## Compatibility Notes
+
+- Built with React and TypeScript for host apps using modern React (including environments like WidgetKit-UI/comptaleyes frontend)
+- Tailwind-compatible output CSS is published as `@ciscode/ui-notification-kit/style.css`
+- Distributed in ESM + CJS with type declarations
+
+## Development Scripts
+
+- `npm run build`
+- `npm run typecheck`
+- `npm test`
+- `npm run lint`
+- `npm run format`

+'@ciscode/ui-notification-kit': minor
+---
+
+Ship the first functional release of NotificationKit-UI.
+
+### Added
+
+- Notification provider and hook API (`NotificationProvider`, `useNotification`)
+- Notification types: success, error, warning, info, loading, default
+- Position support: top-left, top-center, top-right, center, bottom-left, bottom-center, bottom-right
+- Configurable animations (slide, fade, scale), durations, auto-dismiss, close button, actions, and custom icons
+- Store lifecycle with add/update/dismiss/clear/restore and history tracking
+- Route-aware clearing support (`clearOnNavigate`, `navigationKey`)
+- Accessibility support (live-region announcements, ARIA roles, keyboard escape-to-dismiss)
+- Tailwind + RTL styling support and published style asset export (`./style.css`)
+- Test coverage for store behavior, provider behavior, and a11y essentials
+
+### Changed
+
+- Package entry exports updated to align with generated build outputs
+- Notification rendering moved to a portal to avoid stacking-context issues in host apps
+- Layering hardened so notifications stay above dashboard content
+
+### Notes
+
+- Import styles in host apps using: `@ciscode/ui-notification-kit/style.css`

+'@ciscode/ui-notification-kit': minor
+---
+
+Ship the first functional release of NotificationKit-UI.
+
+### Added
+
+- Notification provider and hook API (`NotificationProvider`, `useNotification`)
+- Notification types: success, error, warning, info, loading, default
+- Position support: top-left, top-center, top-right, center, bottom-left, bottom-center, bottom-right
+- Configurable animations (slide, fade, scale), durations, auto-dismiss, close button, actions, and custom icons
+- Store lifecycle with add/update/dismiss/clear/restore and history tracking
+- Route-aware clearing support (`clearOnNavigate`, `navigationKey`)
+- Accessibility support (live-region announcements, ARIA roles, keyboard escape-to-dismiss)
+- Tailwind + RTL styling support and published style asset export (`./style.css`)
+- Test coverage for store behavior, provider behavior, and a11y essentials
+
+### Changed
+
+- Package entry exports updated to align with generated build outputs
+- Notification rendering moved to a portal to avoid stacking-context issues in host apps
+- Layering hardened so notifications stay above dashboard content
+
+### Notes
+
+- Import styles in host apps using: `@ciscode/ui-notification-kit/style.css`

-# React TypeScript DeveloperKit (Template)
+# NotificationKit-UI
 
-Template repository for building reusable React TypeScript **npm libraries**
-(components + hooks + utilities).
+NotificationKit-UI is a React + TypeScript notification library with multiple variants, configurable behavior, accessibility support, and route-aware clearing.
 
-## What you get
+## Features
 
-- ESM + CJS + Types build (tsup)
-- Vitest testing
-- ESLint + Prettier (flat config)
-- Changesets (manual release flow, no automation PR)
-- Husky (pre-commit + pre-push)
-- Enforced public API via `src/index.ts`
-- Dependency-free styling (Tailwind-compatible by convention only)
-- `react` and `react-dom` as peerDependencies
+- Notification types: `success`, `error`, `warning`, `info`, `loading`, `default`
+- Positions: `top-left`, `top-center`, `top-right`, `center`, `bottom-left`, `bottom-center`, `bottom-right`
+- Configurable animation: `slide`, `fade`, `scale`
+- Auto-dismiss with per-notification override
+- Optional action buttons
+- Optional close button
+- Pause on hover and pause on focus
+- Queue limit (FIFO) with history support
+- Route-aware clearing with `clearOnNavigate`
+- Dark mode compatible styles
+- RTL-ready Tailwind setup
+- Accessibility: ARIA roles, live-region announcements, keyboard escape-to-dismiss
 
-## Package structure
+## Installation
 
-- `src/components` – reusable UI components
-- `src/hooks` – reusable React hooks
-- `src/utils` – framework-agnostic utilities
-- `src/index.ts` – **only public API** (no deep imports allowed)
+```bash
+npm install @ciscode/ui-notification-kit
+```
 
-Anything not exported from `src/index.ts` is considered private.
+Also ensure host app peer dependencies are installed:
 
-## Scripts
+- `react`
+- `react-dom`
 
-- `npm run build` – build to `dist/` (tsup)
-- `npm test` – run tests (vitest)
-- `npm run typecheck` – TypeScript typecheck
-- `npm run lint` – ESLint
-- `npm run format` / `npm run format:write` – Prettier
-- `npx changeset` – create a changeset
+## Styling
 
-## Release flow (summary)
+Import package styles once in your app entry file:
 
-- Work on a `feature` branch from `develop`
-- Merge to `develop`
-- Add a changeset for user-facing changes: `npx changeset`
-- Promote `develop` → `master`
-- Tag `vX.Y.Z` to publish (npm OIDC)
+```ts
+import '@ciscode/ui-notification-kit/style.css';
+```
 
-This repository is a **template**. Teams should clone it and focus only on
-library logic, not tooling or release mechanics.
+## Quick Start
+
+```tsx
+import React from 'react';
+import { NotificationProvider, useNotification } from '@ciscode/ui-notification-kit';
+import '@ciscode/ui-notification-kit/style.css';
+
+function Demo() {
+  const { success, error, loading, update } = useNotification();
+
+  const runTask = async () => {
+    const pending = loading({
+      title: 'Please wait',
+      message: 'Processing request...',
+      autoDismiss: false,
+    });
+
+    try {
+      await new Promise((resolve) => setTimeout(resolve, 1200));
+      update({
+        id: pending.id,
+        type: 'success',
+        title: 'Done',
+        message: 'Operation completed',
+        autoDismiss: true,
+      });
+    } catch {
+      error({ title: 'Failed', message: 'Something went wrong' });
+    }
+  };
+
+  return <button onClick={runTask}>Run Task</button>;
+}
+
+export default function App() {
+  return (
+    <NotificationProvider>
+      <Demo />
+    </NotificationProvider>
+  );
+}
+```
+
+## Provider API
+
+`NotificationProvider` props:
+
+- `config?: NotificationProviderConfig`
+- `navigationKey?: string | number`
+
+`navigationKey` can be tied to router location changes. When it changes, notifications with `clearOnNavigate: true` are removed while others remain visible.
+
+### Example with React Router
+
+```tsx
+import { useLocation } from 'react-router-dom';
+import { NotificationProvider } from '@ciscode/ui-notification-kit';
+
+function RootLayout({ children }: { children: React.ReactNode }) {
+  const location = useLocation();
+
+  return <NotificationProvider navigationKey={location.key}>{children}</NotificationProvider>;
+}
+```
+
+## Hook API
+
+`useNotification()` returns:
+
+- `state`
+- `config`
+- `notify(config)`
+- `success(config)`
+- `error(config)`
+- `warning(config)`
+- `info(config)`
+- `loading(config)`
+- `defaultNotification(config)`
+- `update({ id, ...patch })`
+- `dismiss(id)`
+- `clearAll()`
+- `restore(id)`
+
+## Notification Config
+
+Main fields you can pass to `notify` and typed helper methods:
+
+- `title?: string`
+- `message?: string`
+- `body?: ReactNode`
+- `type?: NotificationType`
+- `position?: NotificationPosition`
+- `animation?: { type: 'slide' | 'fade' | 'scale'; durationMs: number }`
+- `autoDismiss?: boolean`
+- `durationMs?: number`
+- `pauseOnHover?: boolean`
+- `pauseOnFocus?: boolean`
+- `closeButton?: boolean`
+- `clearOnNavigate?: boolean`
+- `actions?: { label: string; onClick: () => void }[]`
+- `icon?: ReactNode | null`
+- `onClick?: () => void`
+- `ariaRole?: 'status' | 'alert'`
+
+## Provider Defaults
+
+`NotificationProviderConfig` supports:
+
+- `maxVisible` (default: `5`)
+- `defaultType` (default: `default`)
+- `defaultPosition` (default: `top-right`)
+- `defaultAnimation` (default: `{ type: 'slide', durationMs: 300 }`)
+- `defaultAutoDismiss` (default: `true`)
+- `defaultDurationMs` (default: `4000`)
+- `defaultPauseOnHover` (default: `true`)
+- `defaultPauseOnFocus` (default: `true`)
+- `defaultCloseButton` (default: `true`)
+- `defaultClearOnNavigate` (default: `false`)
+- `defaultAriaRole` (default: `status`)
+- `defaultIcon` (default: `null`)
+- `historyLimit` (default: `20`)
+
+## Accessibility Notes
+
+- Uses ARIA role per notification (`status` or `alert`)
+- Adds live-region announcements for screen readers
+- Supports keyboard escape to dismiss
+- Supports pause-on-focus for better readability
+
+## Compatibility Notes
+
+- Built with React and TypeScript for host apps using modern React (including environments like WidgetKit-UI/comptaleyes frontend)
+- Tailwind-compatible output CSS is published as `@ciscode/ui-notification-kit/style.css`
+- Distributed in ESM + CJS with type declarations
+
+## Development Scripts
+
+- `npm run build`
+- `npm run typecheck`
+- `npm test`
+- `npm run lint`
+- `npm run format`
