Herdr Introduction

Herdr is a terminal multiplexer built for coding agents such as Claude Code and Codex. It keeps the terminals on a server, so your agents keep running when the lid closes or SSH drops. And its sidebar shows, in color, which pane is waiting for your approval.

This course exists to make the operations second nature, the part the official docs only touch briefly. You will create panes, tabs, and workspaces, move between them, name them, and close them. You will read agent states, hear a change happen where you are not looking, and jump straight to it. Three chapters and six lessons later, you move around Herdr without thinking.

The Herdr in the exercises is a simulation running in your browser, matched to the default keys and screens of Herdr 0.8.0. The agent in each pane is a stand-in modeled on the real Claude Code: it only pretends to think, but it keeps you waiting and asks for approval exactly like the real one. Every exercise is graded on where you end up, not on which keys you pressed, so any route to the same place is correct.
