Tmux pane control and cross-pane agent communication. Use tmux-bridge (the high-level CLI) for all cross-pane interactions. Fall back to raw tmux commands only when you need low-level control.

tmux-bridge — Cross-Pane Communication

A CLI that lets any AI agent interact with any other tmux pane. Works via plain bash. Every command is atomic: type types text (no Enter), keys sends special keys, read captures pane content.

DO NOT WAIT OR POLL

Other panes have agents that will reply to you via tmux-bridge. Their reply appears directly in YOUR pane as a [tmux-bridge from:...] message. Do not sleep, poll, read the target pane for a response, or loop. Type your message, press Enter, and move on.

The ONLY time you read a target pane is:

• Before interacting with it (enforced by the read guard)
• After typing to verify your text landed before pressing Enter
• When interacting with a non-agent pane (plain shell, running process)
