claude-tmux-notifier

macOS notifications for Claude Code that switch you back to the right tmux pane when clicked.

What it does

• Stop: when Claude finishes a turn, you get a "Done, waiting for input" notification.
• Permission prompt: when Claude needs your approval, you get a notification with the prompt message.
• Auto-clear: notifications are dismissed when you interact with Claude again (next prompt, tool use, or session end).
• Click-to-focus: clicking a notification activates your terminal app (auto-detected) and switches your tmux client to the originating session and pane.

Requirements

• macOS (uses terminal-notifier)
• terminal-notifier: brew install terminal-notifier
• tmux (optional — with tmux, click-to-focus switches the tmux client back to the originating session+pane; without tmux, click just opens the terminal app)
• jq (for parsing hook payloads; usually preinstalled, otherwise brew install jq)
• A macOS terminal app — the click-to-focus target is auto-detected from $__CFBundleIdentifier (set by macOS to the bundle id of the app that launched the process). Works with Ghostty, iTerm2, Terminal.app, WezTerm, etc., out of the box. To override, set CLAUDE_NOTIFIER_BUNDLE_ID (e.g. com.googlecode.iterm2).
