tmux

• Monitoring AI coding sessions — poll Claude Code or Codex panes to detect prompts awaiting approval and respond automatically.
• Sending input to interactive TUI applications — safely dispatch text and special keystrokes to programs that cannot be driven by a simple shell command.
• Scraping output from long-running processes — capture the last N lines or the full scrollback of any pane for inspection or logging.
• Orchestrating parallel worker sessions — check status across multiple named sessions (e.g. worker-2 through worker-8) and dispatch tasks to each.

• Running one-off shell commands — use the exec tool directly instead; no tmux overhead needed.
• Starting new background processes — use exec with background: true.
• Non-interactive scripts — if the process doesn't need keyboard input, exec is simpler and more direct.
• The target process is not running inside tmux — this skill only works with processes hosted in a tmux session.

Read the last N lines or the entire scrollback history of any tmux pane using capture-pane. Supports targeting specific sessions, windows, and panes via the session:window.pane format.

Send plain text, Enter, Escape, and control sequences (Ctrl+C, Ctrl+D, Ctrl+Z) to any pane. Text and Enter are dispatched in separate calls to avoid multiline paste edge cases in interactive TUIs.

List, select, rename, create, and kill tmux sessions and windows programmatically. Navigate between panes to focus the right target before sending input.

Detect prompts awaiting user approval (e.g. ❯, Yes/No, proceed) by grepping captured pane output, then respond with a keystroke — enabling fully automated AI coding pipelines.

Loop over a named set of sessions to check status or dispatch tasks simultaneously, supporting workflows with multiple parallel worker sessions.

The agent periodically captures the last 10 lines of each worker pane, greps for permission prompts, and sends y + Enter to approve — keeping coding sessions unblocked without human intervention.

An orchestrator agent sends a different task (e.g. Fix the bug in auth.js) to each of several named tmux sessions, then polls their output to collect results when each finishes.

Capture the full scrollback of a build or test session running in the background, search for error patterns, and surface a summary — all without interrupting the running process.

Drive a terminal UI application (such as a REPL or text-mode editor) by sending structured keystrokes and reading the resulting screen state, enabling scripted interaction with tools that have no API.
