+# Desktop Notifications
+
+Fabric supports desktop notifications to alert you when commands complete, which is especially useful for long-running tasks or when you're multitasking.
+
+## Quick Start
+
+Enable notifications with the `--notification` flag:
+
+```bash
+fabric --pattern summarize --notification < article.txt
+```
+
+## Configuration
+
+### Command Line Options
+
+- `--notification`: Enable desktop notifications when command completes
+- `--notification-command`: Use a custom notification command instead of built-in notifications
+
+### YAML Configuration
+
+Add notification settings to your `~/.config/fabric/config.yaml`:
+
+```yaml
+# Enable notifications by default
+notification: true
+
+# Optional: Custom notification command
+notificationCommand: 'notify-send --urgency=normal "$1" "$2"'
+```
+
+## Platform Support
+
+### macOS
+
+- **Default**: Uses `osascript` (built into macOS)
+- **Enhanced**: Install `terminal-notifier` for better notifications:
+
+  ```bash
+  brew install terminal-notifier
+  ```
+
+### Linux
+
+- **Requirement**: Install `notify-send`:
+
+  ```bash
+  # Ubuntu/Debian
+  sudo apt install libnotify-bin
+
+  # Fedora
+  sudo dnf install libnotify
+  ```
+
+### Windows
+
+- **Default**: Uses PowerShell message boxes (built-in)
+
+## Custom Notification Commands
+
+The `--notification-command` flag allows you to use custom notification scripts or commands. The command receives the title as `$1` and message as `$2` as shell positional arguments.
+
+**Security Note**: The title and message content are properly escaped to prevent command injection attacks from AI-generated output containing shell metacharacters.
+
+### Examples
+
+**macOS with custom sound:**
+
+```bash
+fabric --pattern analyze_claims --notification-command 'osascript -e "display notification \"$2\" with title \"$1\" sound name \"Ping\""' < document.txt
+```
+
+**Linux with urgency levels:**
+
+```bash
+fabric --pattern extract_wisdom --notification-command 'notify-send --urgency=critical "$1" "$2"' < video-transcript.txt
+```
+
+**Custom script:**
+
+```bash
+fabric --pattern summarize --notification-command '/path/to/my-notification-script.sh "$1" "$2"' < report.pdf
+```
+
+**Testing your custom command:**
+
+```bash
+# Test that $1 and $2 are passed correctly
+fabric --pattern raw_query --notification-command 'echo "Title: $1, Message: $2"' "test input"
+```
+
+## Notification Content
+
+Notifications include:
+
+- **Title**: "Fabric Command Complete" or "Fabric: [pattern] Complete"
+- **Message**: Brief summary of the output (first 100 characters)
+
+For long outputs, the message is truncated with "..." to fit notification display limits.
+
+## Use Cases
+
+### Long-Running Tasks
+
+```bash
+# Process large document with notifications
+fabric --pattern analyze_paper --notification < research-paper.pdf
+
+# Extract wisdom from long video with alerts
+fabric -y "https://youtube.com/watch?v=..." --pattern extract_wisdom --notification
+```
+
+### Background Processing
+
+```bash
+# Process multiple files and get notified when each completes
+for file in *.txt; do
+    fabric --pattern summarize --notification < "$file" &
+done
+```
+
+### Integration with Other Tools
+
+```bash
+# Combine with other commands
+curl -s "https://api.example.com/data" | \
+    fabric --pattern analyze_data --notification --output results.md
+```
+
+## Troubleshooting
+
+### No Notifications Appearing
+
+1. **Check system notifications are enabled** for Terminal/your shell
+2. **Verify notification tools are installed**:
+   - macOS: `which osascript` (should exist)
+   - Linux: `which notify-send`
+   - Windows: `where.exe powershell`
+
+3. **Test with simple command**:
+
+   ```bash
+   echo "test" | fabric --pattern raw_query --notification --dry-run
+   ```
+
+### Notification Permission Issues
+
+On some systems, you may need to grant notification permissions to your terminal application:
+
+- **macOS**: System Preferences → Security & Privacy → Privacy → Notifications → Enable for Terminal
+- **Linux**: Depends on desktop environment; usually automatic
+- **Windows**: Usually works by default
+
+### Custom Commands Not Working
+
+- Ensure your custom notification command is executable
+- Test the command manually with sample arguments
+- Check that all required dependencies are installed
+
+## Advanced Configuration
+
+### Environment-Specific Settings
+
+Create different configuration files for different environments:
+
+```bash
+# Work computer (quieter notifications)
+fabric --config ~/.config/fabric/work-config.yaml --notification
+
+# Personal computer (with sound)
+fabric --config ~/.config/fabric/personal-config.yaml --notification
+```
+
+### Integration with Task Management
+
+```bash
+# Custom script that also logs to task management system
+notificationCommand: '/usr/local/bin/fabric-notify-and-log.sh "$1" "$2"'
+```
+
+## Examples
+
+See `docs/notification-config.yaml` for a complete configuration example with various notification command options.
