tmux

The skill wraps the standard tmux CLI to expose three core primitives:Capture output — tmux capture-pane reads the visible buffer or full scrollback of any pane and prints it to stdout for the agent to inspect.Send keys — tmux send-keys injects text and special keys (Enter, Escape, Ctrl+C, Ctrl+D, etc.) into a target pane, driving interactive TUIs without a real keyboard.Navigate sessions — the agent can list sessions and windows, select panes, rename or kill sessions, and create new ones — all by composing standard tmux subcommands.Sessions are addressed using tmux's session:window.pane target format (e.g., shared:0.0). Because tmux sessions survive SSH disconnects, the agent can monitor background work that was started earlier and pick up where it left off.

Pane Output Scraping — Capture the last N lines or the entire scrollback history of any pane for programmatic inspection.Keystroke Injection — Send literal text, special keys (Enter, Escape), and control sequences (Ctrl+C, Ctrl+D, Ctrl+Z) to any session.Safe TUI Input — Splits text and Enter into separate sends to avoid paste and multiline edge cases in interactive applications.Parallel Session Coordination — Loop over multiple named sessions (e.g., worker-2–worker-8) to check status and dispatch tasks in bulk.Claude Code Prompt Detection — Grep captured output for prompts (❯, Yes/No, proceed, permission) and auto-approve or respond.Full Session Lifecycle — Create, rename, and kill sessions; list windows and panes; select targets by index.SSH-Persistent Sessions — tmux sessions survive disconnects, so the agent can reconnect and resume monitoring at any time.

tmux — The tmux binary must be installed and available on PATH. This skill does not manage installation of tmux itself; install it via your system package manager (e.g., brew install tmux on macOS or apt install tmux on Debian/Ubuntu). No API keys or cloud services are required.

Claude Code Supervision — Monitor one or more Claude Code sessions, detect permission prompts, and automatically approve or respond without manual intervention.Parallel Worker Orchestration — Dispatch tasks to multiple named worker sessions and poll their output to track progress across a large batch of parallel jobs.Interactive Process Control — Drive any TUI application (REPLs, database shells, ncurses tools) by sending keystrokes and reading responses programmatically.Long-Running Job Monitoring — Scrape output from processes started in detached sessions, even after SSH reconnects, to check logs or detect completion.
