What problem does it solve? When running as an agent inside herdr, a terminal-native agent multiplexer, you need a way to see sibling panes, run commands in parallel terminals, and coordinate with other agents without leaving your own pane. This Skill provides the CLI commands to manage workspaces, tabs, and panes, read other panes' output, and wait for specific states. ## Core Features & Use Cases - Pane and Tab Management: List, create, split, rename, focus, and close workspaces, tabs, and panes using compact session ids. - Output Reading and Waiting: Read another pane's visible or recent scrollback text, and block until specific output text or an agent status (idle, working, blocked, done) appears. - Agent Coordination: Spawn new agent instances, send text or keystrokes to panes, and wait for sibling agents to finish before continuing. - Use Case: Split your pane, run npm run dev in the new pane, wait for the "ready on port 3000" output, then read the server log — all orchestrated from your own agent pane. ## Quick Start Check that HERDR_ENV is set to 1, then run herdr pane list to discover your pane and its neighbors.
