Hypothesis

When you leave your desk for a week with only a phone, the coding agents running on your laptop go dark. If the always-on agent on our server could reach into the laptop and drive those same agents, the machine keeps working while the operator commands it from a Telegram thread.

What we built

A one-way bridge from Hermes, our autonomous agent on the server, to the herdr fleet on the laptop. herdr holds persistent terminal panes, each a running Claude Code lane, and exposes them over a local socket. Hermes reaches that socket through a locked-down SSH key: it may only run herdr ... commands, the connection is pinned to the server's address, and shell metacharacters are refused so nothing but the fleet API can pass. The operator types an instruction to Hermes over Telegram, Hermes spawns or steers a named lane on the laptop, and the lane reports back up the same Telegram thread. A protected orchestrator pane stays open as the standing command session no agent is allowed to close.

Learnings

  • A forced-command SSH key is the right shape for cross-machine agent control. The laptop trusts exactly one verb, herdr, so the blast radius is the fleet API and nothing else on the machine.
  • The submit step is its own gotcha: sending text to a pane does not press Enter. The bridge has to type, find the pane, then send the Enter key separately, or the instruction just sits in the composer.
  • The real limit is reboots. herdr's server only comes back after login, so a laptop that restarts to a lock screen kills every lane with no way to page home. Until auto-login and auto-start are verified, an unattended week means keep the laptop awake, and design every lane to restart cheaply from its own handover file.
  • The bridge proved itself unprompted: minutes after wiring, Hermes opened a check lane on the laptop on its own.

Log

  • 2026-07-15 — Bridge live. Restricted SSH key, laptop-side command shim, and the paired skills on both ends shipped; Hermes drove the laptop fleet from the server the same day.
