beepboop

A Claude Code plugin that plays sounds on every hook event and sends Ghostty OSC 777 desktop notifications when Claude needs attention. Works on macOS, Linux, and WSL.

Features

• Plays a distinct sound for each of the 25 Claude Code hook events
• Sends desktop notifications (via Ghostty OSC 777) when Claude finishes a task or needs input
• Configurable via /beepboop:config skill
• Auto-detects an available audio player on first run (macOS: afplay, Linux: aplay/paplay/pw-play, WSL: Linux players or powershell.exe)

Install

From within Claude Code:

/plugin marketplace add /path/to/beepboop
/plugin install beepboop@beepboop

Uninstall

/plugin uninstall beepboop@beepboop
/plugin marketplace remove beepboop

Configuration

Use the /beepboop:config skill in Claude Code:

/beepboop:config                        # show current config
/beepboop:config enable sounds          # turn sounds on
/beepboop:config disable sounds         # turn sounds off
/beepboop:config enable notifications   # turn notifications on
/beepboop:config disable notifications   # turn notifications off
/beepboop:config set Stop Hero           # change Stop hook sound
/beepboop:config volume 0.5             # set playback volume (0.0–1.0, default 0.2)
/beepboop:config player /usr/bin/aplay  # override audio player
/beepboop:config player ""              # reset to auto-detect

Config file: ~/.claude/plugins/cache/beepboop/beepboop/<version>/settings.json

Notifications

Notifications work across multiple terminals with automatic detection:

• Ghostty — OSC 777 (requires desktop-notifications = true in ~/.config/ghostty/config)
• VSCode, iTerm2, WezTerm — OSC 9 escape sequence
• Other terminals on macOS — osascript system notification (clicking focuses your terminal app, not Script Editor)

Audio Daemon (macOS)

On macOS, beepboop uses a persistent audio mixing daemon (beepboop-daemon.py) to prevent audio corruption when multiple hooks fire in quick succession. Instead of spawning multiple afplay processes, all sounds are mixed into a single stream.

• Socket: /tmp/beepboop-<uid>.sock
• PID file: /tmp/beepboop-<uid>.pid
• Auto-starts on the first hook event that plays a sound
• Automatically stopped on SessionEnd

Manual management

Check if running:

ps aux | grep beepboop-daemon

Stop manually:

kill $(cat /tmp/beepboop-$(id -u).pid)

The daemon auto-starts on the next hook event.
