Remote control tmux sessions for interactive CLIs (python, gdb, git add -p, etc.) by sending keystrokes and scraping pane output. Use when debugging applications, running interactive REPLs (Python, gdb, ipdb, psql, mysql, node), automating terminal workflows, interactive git commands (git add -p, git stash -p, git rebase -i), or when user mentions tmux, debugging, or interactive shells.
