Launch commands in a real pseudo-terminal, detach, reattach later. Cross-platform screen / tmux alternative for AI agents.

What It Does

Creates detached PTY sessions that survive disconnection. Windows (named pipes), macOS, and Linux (Unix sockets). Agents can launch long-running processes, detach, and check back later without blocking.

Supports logs --tail/--follow, session replay, Ctrl+A detach in attached mode, and PowerShell compatibility.
