Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 67 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.01661 |
| Opus 5 | $0.00037 | $0.00830 |
| Sonnet 5 | $0.00015 | $0.00332 |
| Haiku 4.5 | $0.00007 | $0.00166 |
Grade A, and why
herdr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
herdr
herdr is the terminal workspace manager the dotfiles install for coding agents
(workspaces > tabs > panes, with agent state in the sidebar). This skill is the
herdr counterpart of the tmux skill: the same verbs, backed by herdr's own
CLI plus two bundled tools for what the CLI lacks.
Gate first. Every command below talks to the server socket of the pane you
are in. Run test "${HERDR_ENV:-}" = 1; if it fails, say you are not inside
herdr and stop. Never control a herdr session from outside it.
Host-local by design. Everything this skill writes lives under
~/.config/herdr/ (layouts/, config.toml), never in the dotfiles repo.
The fleet baseline for config.toml is ai/herdr/config.toml, rendered by
install_herdr.sh config; per-host changes go through herdr-prefs, which
takes ownership of the file away from install.sh.
Verb map (tmux skill -> herdr)
| tmux-mgr | herdr | Notes |
|---|---|---|
session list/new/attach/kill |
herdr session list/attach <name>/stop <name> |
Named sessions are separate servers; prefer workspaces |
window split, pane split |
herdr pane split --current --direction right|down --cwd "$PWD" --no-focus |
Read the new id from .result.pane.pane_id |
window move/resize |
herdr pane focus/resize --direction ... |
|
capture |
herdr pane read <id> / herdr agent read <name> |
|
agent start |
herdr agent start <name> --kind claude --pane <id> |
Pane must be an idle shell; then herdr agent prompt <name> "..." --wait |
agent list/complete |
herdr agent list / herdr agent wait <name> + agent read |
States: working, blocked, done, idle, unknown |
save / restore |
scripts/herdr-layout save|restore <name> |
No CLI equivalent in herdr; see below |
| (none) | scripts/herdr-prefs status|get|set|reset |
Host-local preferences |
The installed binary is the syntax authority: herdr <group> with no
subcommand prints that group's usage. Do not run bare herdr (it attaches the
TUI). Never answer a blocked approval dialog on the user's behalf.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

herdr is a skill published in the GitHub repository sfc-gh-eraigosa/dotfiles (46 stars, last pushed today), licensed Apache-2.0. It adds 74 tokens to every session and 1,661 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
