VueUse Development

Instructions

VueUse Integration Pattern

Always use VueUse composables when working with browser APIs, complex event handling, or performance optimizations:

import {
  useMagicKeys,
  useClipboard,
  useLocalStorage,
  useThrottleFn,
  useWindowSize,
  useEventListener
} from '@vueuse/core'

// Enhanced keyboard shortcuts
const { ctrl, shift, space } = useMagicKeys()

// Clipboard functionality
const { copy, copied, isSupported } = useClipboard()

// Persistent storage
const settings = useLocalStorage('app-settings', defaults)

// Performance optimization
const throttledUpdate = useThrottleFn(() => {
  updateCanvas()
}, 16)

// Responsive behavior
const { width, height } = useWindowSize()

// Event handling with cleanup
useEventListener('keydown', handleKeydown, { passive: true })

Key Requirements

• Always check browser compatibility: if (typeof window !== 'undefined')
• Use proper TypeScript interfaces for all props and returns
• Handle permissions for browser APIs (notifications, clipboard)
• Implement fallbacks for unsupported features
• Use throttling/debouncing for performance-critical operations
• Clean up resources automatically with VueUse's built-in cleanup

Common Patterns

• Event Handling: useEventListener for global events with automatic cleanup
• Storage: useLocalStorage/useSessionStorage for persistent state
• Performance: useThrottleFn/useDebounceFn for optimization
• Browser APIs: useClipboard, useNotification, useNetwork for web features
• Responsive Design: useWindowSize, useBreakpoints for adaptive layouts
• Keyboard Shortcuts: useMagicKeys for enhanced keyboard interactions

This skill ensures modern, efficient use of VueUse composables throughout the productivity application while maintaining performance and browser compatibility.

MANDATORY USER VERIFICATION REQUIREMENT

Policy: No Fix Claims Without User Confirmation

CRITICAL: Before claiming ANY issue, bug, or problem is "fixed", "resolved", "working", or "complete", the following verification protocol is MANDATORY:

Step 1: Technical Verification

• Run all relevant tests (build, type-check, unit tests)
• Verify no console errors
• Take screenshots/evidence of the fix

Step 2: User Verification Request

REQUIRED: Use the AskUserQuestion tool to explicitly ask the user to verify the fix:

"I've implemented [description of fix]. Before I mark this as complete, please verify:
1. [Specific thing to check #1]
2. [Specific thing to check #2]
3. Does this fix the issue you were experiencing?

Please confirm the fix works as expected, or let me know what's still not working."

Step 3: Wait for User Confirmation

• DO NOT proceed with claims of success until user responds
• DO NOT mark tasks as "completed" without user confirmation
• DO NOT use phrases like "fixed", "resolved", "working" without user verification

Step 4: Handle User Feedback

• If user confirms: Document the fix and mark as complete
• If user reports issues: Continue debugging, repeat verification cycle

Prohibited Actions (Without User Verification)

• Claiming a bug is "fixed"
• Stating functionality is "working"
• Marking issues as "resolved"
• Declaring features as "complete"
• Any success claims about fixes

Required Evidence Before User Verification Request

1. Technical tests passing
2. Visual confirmation via Playwright/screenshots
3. Specific test scenarios executed
4. Clear description of what was changed

Remember: The user is the final authority on whether something is fixed. No exceptions.
