Common questions.

Does it slow your agent down?+
No. Each hook backgrounds the player and returns instantly. No daemon, no network, no telemetry: a shell script and 32 small mp3s.
Can I use my own sounds?+
Yes. Drop a folder at sounds/<name>/<event>/*.mp3 and it joins the rotation. Missing an event folder stays silent for that voice; it never borrows another.
How do I turn it off?+
/beep-boop:toggle, or set ENABLED=0 in ~/.claude/beep-boop/config. Uninstall is one command.
Windows?+
Not yet. The script no-ops on unsupported platforms, so nothing breaks. PRs welcome.
Is the audio really free?+
chime, hum, and ping are original tones, public domain (CC0). oak is sampled from a recording of a living oak, credited in sounds/CREDITS.md. The code is MIT.
