Claude Bell

Send macOS notifications to communicate with users outside the terminal.

When to Use

Use for:

  • Task completion (build done, tests passed, deploy finished)
  • Errors requiring attention
  • Confirmation before destructive operations
  • Collecting text input (release notes, commit messages)
  • Status updates during long operations

Don't use for:

  • Routine progress updates (use terminal)
  • Information user is actively watching
  • Rapid-fire notifications (spam)

Quick Reference

Pattern Command
Alert cb -t "Done" -m "Build complete"
Alert with sound cb -t "Done" -m "Build complete" --sound Glass
Yes/No cb -t "Deploy?" -a "Yes,No" --default "No"
Multiple choice cb -t "Action" -a "A,B,C,Cancel" --default "Cancel"
Text input cb -t "Notes" -r "Enter notes..." --timeout 5m
Template cb --template build-done --var 'project:myapp'

Exit Codes

Code Meaning Action
0 Success Proceed with returned value
1 Timeout Use --default value
2 Dismissed Use --default value
3 User error Check arguments
4 System error Check permissions (cb doctor)
5 App error Report bug

Critical Rules

  1. Always provide --default for interactive notifications
  2. Always check exit code - don't assume success
  3. Use --timeout for non-critical prompts
  4. Don't spam - one notification per logical event
