Tmux

This wraps tmux with a clean interface for driving interactive CLIs like Python REPLs, gdb, and other terminal programs. It runs sessions on isolated sockets so Claude's work doesn't collide with your personal tmux setup, sends keystrokes programmatically, and scrapes pane output to see what happened. The wait-for-text helper polls for prompts or completion markers so you can synchronize on slow commands without racing. Useful when you need Claude to debug with lldb, run interactive database shells, or babysit long-running terminal processes. The convention of printing monitor commands for users is thoughtful. Works on stock Linux and macOS tmux without custom config.
