**herdr** is a terminal-native multiplexer for managing multiple AI coding agents in workspaces with tiled panes.

It auto-detects agents like pi, Claude Code, Codex, and Droid via process and output analysis, displaying states (blocked, done, working, idle) in a sidebar with rollups and optional notifications. Agents integrate via socket API or CLI skills to create panes, spawn tasks, and coordinate autonomously; install via curl on Linux/macOS.
