tmux

Control tmux sessions by sending keystrokes and reading pane output for interactive CLI management. Control tmux sessions by sending keystrokes and reading output. Essential for managing Claude Code sessions. ✅ USE this skill when: ❌ DON'T use this skill when: For interactive TUIs (Claude Code, Codex, etc.), split text and Enter into separate sends to avoid paste/multiline edge cases: - Send text input and special keys (Enter, Ctrl+C, Ctrl+Z) to tmux panes; capture output via capture-pane to monitor long-running processes and interactive prompts - Target sessions, windows, and panes using session:window.pane notation; navigate and manage multiple parallel sessions programmatically - Designed for monitoring Claude Code sessions and approving interactive prompts; sessions persist across SSH disconnects - Requires tmux to be installed; use for interactive applications only, not one-off commands or non-interactive scripts - Monitoring Claude/Codex sessions in tmux - Sending input to interactive terminal applications - Scraping output from long-running processes in tmux - Navigating tmux panes/windows programmatically - Checking on background work in existing sessions - Running one-off shell commands → use exec tool directly - Starting new background processes → use exec with background:true - Non-interactive scripts → use exec tool - The process isn't in tmux - You need to create...
