AI agents call list_rich_menus to retrieve information from LineWhiz without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing rich menu configurations without side effects. Listing data is a read-only operation that poses minimal risk, even in a messaging context, as it only exposes metadata about UI elements already created. The severity is low because disclosure of rich menu configurations poses no direct operational, financial, or security harm.
From the tool's definition Tool name 'list_rich_menus' and description 'List all rich menus created for this LINE OA' indicate a retrieval operation with no modification, deletion, or execution of external actions.
