🔔 Claude Code Notification Hooks

⚠️ DEPRECATED: This project has been superseded by cat-ccnotify-hook. Please use the new standalone package for better performance and easier installation.

Enhanced Claude Code experience with automatic desktop notifications and contextual sounds for all events. No manual notification calls needed - works automatically with all Claude Code operations!

✨ Features

• 🔔 Automatic Notifications: Intercepts ALL Claude Code notifications and enhances them
• 🎵 Contextual Sounds: Different sounds for success, error, warning, and other event types
• 🚀 Zero Configuration: Automatic detection and enhancement of notification types
• 📋 Smart Sound Mapping: Intelligent analysis of notification content for appropriate sounds
• 🖱️ Native System Integration: Uses macOS/Windows/Linux native notification systems

🚀 Quick Start

Method 1: One-Command Setup (Recommended)

Run this in Claude Code:

cd /path/to/ccnotify && npm run setup-hooks

Method 2: Manual Setup

1. Clone and build:

git clone <this-repository>
cd ccnotify
npm install && npm run build

2. Run setup:

npm run setup-hooks

3. Restart Claude Code if it's currently running

3. That's It!

All Claude Code notifications will now automatically have enhanced sounds and styling. No additional configuration needed!

📱 How It Works

The notification hook automatically detects and enhances all Claude Code notifications:

Automatic Sound Assignment

• ✅ Success/Completion → Glass sound (macOS)
• 🚨 Errors/Failures → Basso sound (macOS)
• ⚠️ Warnings/Attention → Sosumi sound (macOS)
• 💡 Info/Updates → Blow sound (macOS)
• ⏳ Progress/Ongoing → Tink sound (macOS)

Examples in Action

# Building a project
npm run build
# → Automatic success notification with Glass sound when complete
# → Automatic error notification with Basso sound if failed

# Running tests  
npm test
# → Automatic progress notification with Tink sound while running
# → Automatic completion notification when finished

# Git operations
git push origin main
# → Automatic notifications for each step with appropriate sounds

🎵 Available Sounds

Sound	Use Case	macOS Sound
success	Task completion, success	Glass
error	Errors, failures	Basso
warning	Warnings, attention needed	Sosumi
info	Information, status updates	Blow
progress	Progress updates, ongoing work	Tink
reminder	Reminders, prompts	Ping
default	System default notification sound	-
silent	No sound	-

🛠️ Advanced Configuration

Customizing Sound Mappings

Edit the hook script at hooks/notification-hook.js to customize sound mappings:

// Example: Add custom sound rules
const customSoundRules = [
  { pattern: /deployment/i, sound: 'Ping' },
  { pattern: /security/i, sound: 'Funk' },
  { pattern: /backup/i, sound: 'Purr' }
];

Troubleshooting

Hook not working?

# Check if hook is properly installed
cat ~/.config/claude-code/settings.json | grep -A 10 "hooks"

# Verify hook script is executable
ls -la hooks/notification-hook.js

# Re-run setup if needed
npm run setup-hooks

Sounds not playing?

# Test system sound (macOS)
afplay /System/Library/Sounds/Glass.aiff

# Check notification permissions in System Preferences

🌍 Real-World Examples

Automatic Enhancement Examples

Claude Code Operations → Enhanced Notifications

# File operations
"Create a new React component"
→ ✅ "Component created successfully" + Glass sound

# Build processes  
"Run the build process"
→ ⏳ "Build in progress..." + Tink sound
→ ✅ "Build completed successfully" + Glass sound

# Error scenarios
"Fix the TypeScript errors"
→ 🚨 "3 type errors found" + Basso sound

# Git operations
"Commit these changes"
→ ✅ "Changes committed successfully" + Glass sound

🔧 Development

Development Commands

npm run dev    # Development mode with auto-reload
npm run build  # Production build
npm start      # Start production server

Platform Support

• macOS: Full native support with osascript and system sounds
• Windows/Linux: Cross-platform support via node-notifier package

Architecture

• Type-safe TypeScript implementation
• MCP (Model Context Protocol) compliant
• Automatic platform-specific implementation switching
• Extensible notification type system

📋 Technical Details

Hook Architecture

The notification hook intercepts Claude Code's notification system and enhances it:

1. Interception: Hook receives all notification calls from Claude Code
2. Analysis: Analyzes notification content using pattern matching
3. Enhancement: Adds appropriate sounds and styling based on content
4. Native Integration: Uses platform-specific notification APIs

Installation Structure

~/.config/claude-code/settings.json  # Claude Code configuration
hooks/notification-hook.js            # Main hook script  
dist/index.js                        # Built MCP server (optional)
scripts/setup-hooks.js               # Automated setup script

Platform Support

• macOS: Full native support with osascript and system sounds
• Windows/Linux: Cross-platform support via node-notifier package

Legacy MCP Server (Optional)

For advanced users who want manual notification control, the MCP server is still available:

{
  "mcpServers": {
    "ccnotify": {
      "command": "node",
      "args": ["/absolute/path/to/ccnotify/dist/index.js"]
    }
  }
}
