tmux-cli

The documented tmux-cli capability to send and execute arbitrary shell commands in other tmux panes is functionally plausible for agent-to-agent communication, but it is inherently high risk. Primary concerns: arbitrary command execution in contexts with access to secrets, lack of documented safeguards/least-privilege controls, and recommending an external installer without provenance. If you plan to use this tool in sensitive environments, verify the implementation and origin of claude-code-tools, require explicit consent/authorization for cross-pane commands, add auditing and command whitelists, and prefer sandboxing or minimized privileges for target shells. Treat as high-impact functionality that requires careful operational controls.
