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.
