Hark the Herald

Voice alerts for your AI coding agents

Run several coding agents at once and you lose track of which one needs you. Hark the Herald says it out loud, by name, the moment a session wants your approval or is waiting on you.

Plays through your device’s voice as a preview. On your Mac you’ll hear the Daniel voice.

Set up all your agents in one command

Terminal - zsh
curl -fsSL https://harktheherald.dev/install.sh | bash

Wires up whichever of the four you use, on macOS. Backs up first, safe to run twice.

Or pick one agent

Only run one? Set up just that agent, and read exactly what it will do.

Each agent hands off a little differently, so what you hear varies slightly. The pages above spell out each one, including Codex, which announces when it is ready but keeps approvals in the terminal.
