## What is Crook for Herdr?

Your agent is waiting for an answer, and you're not at your desk. Crook lets you watch and steer the agents running in Herdr on your Mac, from your iPhone or iPad.
Agents waiting for you come first, and you answer their prompts with one tap. Open the real terminal when you need it.
Free, with no account and no SSH setup. Crook connects only to your own Mac.

EVERY AGENT AT A GLANCE
Agents that need you come first: waiting for input, done, working, idle. The same marks as Herdr and the same tab names (1:claude).

THE REAL TERMINAL
Open any pane to see the live, colored terminal. A row of extra keys gives you esc, tab, arrows, ctrl and ^C.

ANSWER PROMPTS
When an agent asks for permission, tap the choice it offers — Yes, Allow once, and so on — right from the list.

SEND INSTRUCTIONS
Type or dictate (speech is turned into text on the device), attach photos, pick files with @ and run / commands. Start a new workspace with Claude Code or Codex.

NOTIFICATIONS
Get notified when an agent is waiting for you or has finished, even when Crook is in the background. By default, notifications arrive when you're away from your Mac; you can change this in Settings. Quiet hours and per-workspace mute.

USAGE AND MODELS
See context, tokens, 5-hour and weekly limits and cost, and switch models and effort for Claude Code, Codex and OpenCode.

IPAD
Spaces and agents on the left, the session on the right — like Herdr on the Mac. Keyboard and Stage Manager friendly.

CONNECTS ONLY TO YOUR MAC
Crook tries Tailscale, then the same Wi‑Fi, then an encrypted relay. On Wi‑Fi and the relay, everything is end‑to‑end encrypted with your Mac's key. No account, no analytics, no ads.
Recommended: Tailscale (free for personal use) on your Mac and iPhone — Crook then connects directly from anywhere, with no time or data limit. Without it, the relay works for up to 120 minutes and 200 MB per Mac per day.

WHAT YOU NEED
• A Mac running Herdr 0.9 or later and Node.js 23.6 or later
• The free Crook plugin on the Mac: herdr plugin install algorist-dev/herdr-crook (github.com/algorist-dev/herdr-crook)
Then press prefix+m in Herdr and scan the QR code.

Supported agents: Claude Code, Codex, OpenCode, GitHub Copilot CLI, Gemini CLI (with an API key), Pi and Hermes, plus any terminal pane. Hermes notifies you only when it's waiting for approval; working and done aren't shown.

Crook is made by Algorist and is not affiliated with the Herdr project.

## Version history (last 4 releases)

### 1.1.1 — 2026-11-11

Исправления:
Crook больше не зависает на «Подключение…», если Mac не отвечает, а пробует следующий способ подключения.
При переключении на Mac, QR-код которого вы ещё не отсканировали заново, экран предыдущего Mac больше не остаётся.
Когда один Mac исчерпает дневной лимит сервера-ретранслятора, остальные ваши Mac смогут им пользоваться.
Если режим YOLO включён по умолчанию, новые рабочие пространства теперь запускаются в режиме YOLO и с агентами, отличными от Claude.
«Заглушить это рабочее пространство» теперь подтверждается на том же экране.

### 1.1.0 — 2026-11-10

Notifications now arrive even when Crook is in the background, when you're away from your Mac (you can change this in Settings).
New agents: Gemini CLI (with an API key), Pi and Hermes.
To use these, update the plugin on your Mac: run herdr plugin update, then restart Herdr. Restarting stops running agents, so do it at a good stopping point.

### 1.0.1 — 2026-11-09

Fixed an issue where a conversation could stay loading after returning to the app.
Fixed the terminal input bar appearing too small with its hint text cut off.

### 1.0.0 — 2026-11-08

No release notes.
