WHAT IT DOES

What tmux_monitor_pane does on TmuxControlLib MCP Server

AI agents invoke tmux_monitor_pane to trigger actions in TmuxControlLib MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why tmux_monitor_pane needs a policy

The tool name suggests monitoring a tmux pane, which could be a Read operation (observing output), but given the server's broader capabilities to control tmux (including sibling tools like kill_pane, create_session, send commands), and the ambiguity of 'monitor' (which could trigger actions or scripts), Execute is chosen as the most cautious classification. Confidence is low due to the empty description.

From the tool's definition Tool name 'tmux_monitor_pane' on a server that 'Enables Claude to control tmux sessions, manage windows and panes'; description is empty.
