AI agents call obtener_calificaciones to retrieve information from Moodle without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves educational performance data from Moodle's gradebook without modifying, creating, or deleting anything. It has no side effects and poses minimal security risk even if misused by an agent, as it only exposes grade information that users would typically be authorized to view.
From the tool's definition Tool name and description indicate data retrieval only: 'Get gradebook entries for a user in a course' with return values 'raw/max grade, item name, module type, feedback'.
