What c-notify does

This skill teaches the coding agent how to run terminal-notifier on macOS. The assistant triggers desktop banners, sets custom titles, adds default alert sounds, or assigns a custom application icon.

macOS notification banners truncate long text. Keep them brief. Using the -group flag prevents notification clutter by replacing previous alerts in the same stream. Banners can also open URLs or switch focus to specific apps when clicked.

The commands fail completely without terminal-notifier available in your macOS environment.

What it helps with

alert the user with audio when a long build completes
create clickable notification banners that open a pull request URL
bundle progress updates under a shared group to avoid desktop clutter
activate a specific desktop app when an alert is clicked

Example prompts for the agent

Send a native sound notification once the build finishes.
Post a desktop alert with a link to the merged PR.
Report migration progress in the terminal using the migrate notification group.

# Notifications (terminal-notifier)

```bash
# Simple notification
terminal-notifier -title "OpenPaw" -message "Task complete!"

# With subtitle and sound
terminal-notifier -title "Build" -subtitle "Project X" -message "Done!" -sound default

# Open URL when clicked
terminal-notifier -title "PR Merged" -message "Click to view" -open "https://github.com/..."

# Activate app when clicked
terminal-notifier -title "Music" -message "Now playing" -activate "com.spotify.client"

# Group notifications (replaces previous in same group)
terminal-notifier -title "Progress" -message "50%" -group "build"
terminal-notifier -title "Progress" -message "100%" -group "build"

# Remove a notification group
terminal-notifier -remove "build"

# Custom app icon
terminal-notifier -title "Alert" -message "Hello" -appIcon /path/to/icon.png
```

## Guidelines

- Use notifications to alert the user when long tasks complete
- Group related notifications so they don't spam
- Add `-sound default` for important alerts
- Use `-open URL` to make notifications actionable
- Keep messages short — notifications truncate long text
