Desktop Notification On Stop

{
  "description": "Sends a native desktop notification when Claude Code finishes responding. Uses the Stop hook event so you get a single notification per response instead of one per tool call (which is very noisy with PostToolUse). Supports macOS (osascript) and Linux (notify-send). Useful when you switch to another window while Claude works — you'll get a notification when it's ready for your input.",
