wtf is agentslate?

AgentSlate is an iPhone app that lets you supervise AI coding agents running on your Mac inside a tool called Herdr, without needing to sit at your keyboard. If you can see your coding agents on a monitor but your keyboard is out of reach, you can tap the agent you're watching on your phone and send it a key press, an approval shortcut, or a short piece of text. The terminal output itself stays on the Mac. Your phone only shows the status of each agent, such as which ones are currently blocked waiting for your input, and gives you buttons to respond. You can send basic keys like arrows, Enter, Escape, and Tab, use Accept or Deny shortcuts when a supported agent is waiting on a decision, or dictate short text using Apple's on-device voice transcription, which only sends the resulting text, not audio, to the Mac. Under the hood, a small Rust program runs on the Mac and finds the Herdr sessions and agents there. The iPhone app connects to that Rust bridge over Tailscale, a private networking tool, using a one-time six-digit pairing code that expires after ten minutes and locks after five failed attempts. Each paired phone gets its own revocable credential, and the bridge only listens on private addresses, never on the open internet. The app also includes an offline demo mode with fixed sample agents, so you can try out the interface without setting up Herdr or Tailscale first. Building it requires a Mac with Xcode 26, an iPhone or simulator running iOS 26, and for live control, Herdr 0.7.4 or newer plus Tailscale on both devices. The project is an independent effort not affiliated with Herdr, Tailscale, or Apple, and it is released under the MIT license, meaning it can be freely used, modified, and redistributed.
