@deevus/pi-zmx

April 24, 2026 · View on GitHub

A pi extension that executes shell commands inside persistent zmx sessions.

Features

  • Persistent sessions — filesystem effects, background processes, and exported env vars survive across tool calls
  • Non-blockingzmx_run sends commands and returns immediately; use zmx_wait when you need to block
  • Human-in-the-loop — start a process, prompt the user to attach and enter a password or interact, then continue
  • Auto session naming — defaults to the pi session display name if set; otherwise requires an explicit session name

Requirements

zmx must be installed and on your PATH:

brew install neurosnap/tap/zmx

Or download a binary directly from zmx.sh.

Install

pi install npm:@deevus/pi-zmx
