Installation

For AI Agents (Automated Setup)

If you're an AI agent setting this up for a user, run these commands:

# 1. Install the plugin globally
npm install -g opencode-notification-macos

# 2. Configure default sounds interactively
npx opencode-notification-macos config

# 3. Add to OpenCode configuration
cat >> ~/.config/opencode/opencode.jsonc << 'EOF'
{
  "plugin": [
    "opencode-notification-macos"
  ]
}
EOF

Manual Installation

npm install -g opencode-notification-macos

Then add to your ~/.config/opencode/opencode.jsonc:

{
  "plugin": [
    "opencode-notification-macos"
  ]
}

Configuration

Interactive Configuration (Recommended)

# Configure sounds interactively

AI Agent Setup Instructions

If you are an AI assistant reading this to set up the plugin for a user, follow these exact steps:

Step 1: Check Prerequisites

# Verify macOS
sw_vers -productName

# Verify OpenCode is installed
which opencode

Step 2: Install Plugin

npm install -g opencode-notification-macos

Step 3: Create Configuration

Option A - Interactive (recommended):

npx opencode-notification-macos config

Option B - Create config file directly:

mkdir -p ~/.config/opencode
cat > ~/.config/opencode/opencode-notification-macos.json << 'EOF'
{
  "sound": true,
  "notification": true,
  "showProjectName": true,
  "sounds": {
    "complete": "Glass",
    "error": "Basso",
    "question": "Ping",
    "permission": "Tink",
    "subagent_complete": "Pop"
  }
}
EOF

Step 4: Update OpenCode Config

# Read current config
cat ~/.config/opencode/opencode.jsonc

# Add plugin to the plugin array
# If opencode.jsonc exists, add "opencode-notification-macos" to the plugin array
# If it doesn't exist, create it with the plugin

Step 5: Test

# Test sound
npx opencode-notification-macos preview

# Test with OpenCode
opencode "say hello and wait for my response"

Troubleshooting

No sound playing?

1. Check system volume:

   afplay /System/Library/Sounds/Glass.aiff
   

2. Check notification permissions:

   • System Settings → Notifications → Script Editor
   • Ensure notifications are enabled

3. Verify config:

   npx opencode-notification-macos show
   

Plugin not loading?

1. Check OpenCode config syntax:

   cat ~/.config/opencode/opencode.jsonc
   

2. Clear OpenCode cache:

   rm -rf ~/.cache/opencode
   

3. Restart OpenCode

Permission denied errors?

The plugin uses osascript for notifications. Grant permissions:

• System Settings → Privacy & Security → Automation
• Ensure your terminal has permission to control System Events

Development

How It Works

This plugin replaces external notification libraries with native macOS commands:

• Sounds: Uses afplay (built into macOS) to play system sounds from /System/Library/Sounds/
• Notifications: Uses osascript (AppleScript) to display native macOS notifications
• Zero Dependencies: No npm packages required for core functionality
