setup-herdr

setup-herdr is a skill for Claude Code from atman-33/workhub. It costs 59 tokens per session (2,017 once invoked), scanned D, original, MIT.

A setup guide for installing herdr, a terminal-based tool for running multiple agent sessions, and connecting it to Claude Code and OpenCode. It also configures shell startup behavior.

In plain words
What is it for?
Use it when installing or configuring herdr across Windows and WSL, connecting coding agents, or replacing an existing Zellij startup block.
Why use it?
It brings installation, integrations, startup settings, and existing Zellij autostart changes into one repeatable setup process.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

setup-herdr scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task

Install herdr (https://herdr.dev), a terminal-native agent multiplexer, wire up its Claude Code / OpenCode integrations, and configure shell profiles so herdr launches automatically on startup — replacing any existing Zellij autostart installed by setup-zellij.

Environment note: this session can be hosted on either side

This skill touches both a Windows environment and a WSL environment, and the agent session driving it can be hosted on either — the interop direction flips accordingly:

  • Hosted in WSL: reach Windows via powershell.exe/pwsh.exe, and read/edit Windows profile files directly at their /mnt/c/... path rather than shelling a multi-line edit through powershell.exe -Command — quoting an edit through a nested shell is fragile; a direct file edit is not (the same class of problem step 4's here-string warning describes).
  • Hosted on Windows: reach WSL via wsl -- <command>, as this skill's snippets show by default.

Determine which applies once, then use the matching direction for every step below. The same preference — direct file access over a shell-quoted command — also applies to the idempotency checks in steps 1, 3, and 4: read a file's content and inspect it rather than piping it through grep/Select-String across the interop boundary.

Steps

1. Check herdr installation (per environment)

A PATH-only check false-negatives: herdr's own installer doesn't add itself to PATH (see step 2), so the binary can be present — even running — without Get-Command/ which finding it. Check, in order, until one hits:

Windows: Get-Command herdr -ErrorAction SilentlyContinue → known install dirs (e.g. Test-Path "$env:LOCALAPPDATA\Programs\Herdr\bin\herdr.exe") → a running process (Get-Process herdr -ErrorAction SilentlyContinue).

WSL: which herdr$HOME/.local/bin/herdr (the installer's default target).

Record whichever path resolved it — step 4 needs it to invoke herdr if it never lands on PATH. If found by any check, mark the environment "already installed" and skip to step 3 for it. Only when every check is empty, continue to step 2 for that environment.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup-herdr is a skill published in the GitHub repository atman-33/workhub (2 stars, last pushed today), licensed MIT. It adds 59 tokens to every session and 2,017 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
