Control Herdr, the terminal multiplexer for coding agents. Use when the user mentions Herdr or another skill delegates pane control, including concise pane naming, inspection, commands, and agents. Integrates with vd:worktree, vd:codex-workflow, and vd:ultracook. Requires HERDR_ENV=1.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. …

How to install
mdr add vanducng/skills/herdr@sha256:9e90d1c1fdbd5ba5The line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
