PingMyBell

pingmybellearly alpha · macOS, from source

PingMyBell is the Sothis suite’s bell: free, offline voice notifications and a notch command centre for a fleet of Claude Code agents. Each agent gets a distinct OS-native voice, and a notch-style island lets you approve or deny agent actions and jump to any session’s terminal in one click.

Why it exists

Run several agents in parallel and the bottleneck becomes you noticing them. Sessions finish, or block on a permission prompt, while you are looking somewhere else.

What it does

  • A distinct OS-native voice per agent, speaking a short summary the moment a session completes or blocks.

  • A notch-flush island that toasts events and pins approvals — and never steals focus.

  • Approve or deny gated tool calls without going back to the terminal.

  • Fails open by design: a broken or absent PingMyBell never blocks or alters agent behaviour.

Install and run

Build from source

$cargo build --release --workspace

Clone the repo first. No signed release yet — this is the honest install path, and the README walks the rest.

Installing the whole suite at once is a different path —the plugins first, then every CLI in one shot.
