Tip: Point CLAUDE_CLIENT_PRESENCE_FILE at a Marker to Auto-Silence Mobile Push While at the Keyboard
Claude Code Docs·low signal
Claude Code's new `CLAUDE_CLIENT_PRESENCE_FILE` env var suppresses mobile push notifications whenever the marker file it points to exists, so you only get phone alerts when you've actually stepped away. Wire the file's presence to your terminal focus (or a tmux/IDE hook) to avoid duplicate notifications during active sessions — a small but real ergonomics win for the increasingly common laptop-plus-phone monitoring setup.
