Check pane_current_command before sending keys to tmux windows. If the pane is running a shell (bash, zsh, etc.), Claude Code has exited and user text must not be forwarded — it would execute as shell commands. Guards added to: send_to_window (safety net), text_handler (with auto-unbind), esc_command, usage_command, and screenshot key-press callback. https://claude.ai/code/session_016c4b8ioybZyscNayeY6Y18
When send_to_window detects the pane is running a shell, it now captures the pane content and looks for: - "Stopped ... claude" → sends "fg" (suspended process) - "claude --resume <id>" → sends the resume command Waits up to 3s (fg) or 15s (--resume) for Claude Code to take over the terminal, then sends the user's original text. If no resume command is found, the text_handler unbinds the topic and tells the user to start a new session. https://claude.ai/code/session_016c4b8ioybZyscNayeY6Y18
…_pane Reduces tmux subprocess calls from ~120/s to ~21/s with 20 windows by: - Adding 1-second TTL cache to list_windows() (all callers in the same poll cycle share one tmux enumeration instead of N) - Unifying capture_pane() to always use direct `tmux capture-pane` subprocess (plain text mode previously used libtmux which generated 3-4 tmux round-trips per call) - Invalidating cache on mutations (create/kill/rename) https://claude.ai/code/session_016c4b8ioybZyscNayeY6Y18
