# Herdr Herdr is a terminal multiplexer and runtime for coding agents. It organizes terminals into workspaces, tabs, and panes, detects agent identity and status, and exposes the running session through the `herdr` CLI. This skill adapts the [official Herdr agent skill](https://github.com/herdrdev/herdr/blob/master/SKILL.md) to the `vd:` workflow. The installed CLI remains authoritative when its syntax differs from this file; `herdr --skill` (0.8.0+) prints the exact skill bundled with the running binary. ## Scope and routing | Need | Owner | | --- | --- | | Inspect or control persistent visible panes, processes, output, and agent state | `vd:herdr` | | Create an isolated checkout with copied env, ports, installs, and lifecycle hooks | `vd:worktree` | | Run a deterministic structured fan-out or pipeline without needing visible panes | `vd:codex-workflow` | | Conduct an end-to-end build, review, and ship workflow | `vd:ultracook` | Mentioning Herdr authorizes control of the requested Herdr session. It does not authorize spawning agents, parallel work, new worktrees, merges, deployments, or destructive cleanup. Require the user's explicit request for those actions. Before issuing any control command, check that this agent is running inside a Herdr-managed pane: ```bash test "${HERDR_ENV:-}" = 1 ``` If the check fails, say that you are not running inside Herdr and stop. Do not inspect or control the focused Herdr session from outside Herdr. When the check passes, the `h...
