tmux-cli

Instructions

Use the tmux-cli command to communicate with other CLI Agents or Scripts in other tmux panes. Do tmux-cli --help to see how to use it!

This command depends on installing the claude-code-tools. If you get an error indicating that the command is not available, ask the user to install it using: uv tool install claude-code-tools.

Key Commands

Execute with Exit Code Detection

Use tmux-cli execute when you need to know if a shell command succeeded or failed:

tmux-cli execute "make test" --pane=2
# Returns JSON: {"output": "...", "exit_code": 0}

tmux-cli execute "npm install" --pane=ops:1.3 --timeout=60
# Returns exit_code=0 on success, non-zero on failure, -1 on timeout

This is useful for:

  • Running builds and knowing if they passed
  • Running tests and detecting pass/fail
  • Multi-step automation that should abort on failure

Note: execute is for shell commands only, not for agent-to-agent chat. For communicating with another Claude Code instance, use send + wait_idle + capture instead.
