AI agents call wp_widget_list to retrieve information from Wp Cli 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 widget configuration data from WordPress sidebars without creating, modifying, deleting, or executing any changes. It is purely informational with no side effects, fitting the Read category. Severity is low because disclosure of widget configuration poses minimal security risk and has no blast radius for accidental misuse.
