AI agents call get_windows to retrieve information from Desk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve or list open windows and their properties—a read-only operation that retrieves state information from the desktop environment. It has no destructive, write, execute, or financial impact. The empty description lowers confidence slightly, but server context strongly suggests informational querying.
