WHY IT NEEDS A POLICY

Why create_grid_container needs a policy

The tool creates a new grid container in RSpace, which adds data to the research management system. This is a reversible Write operation—containers can be deleted or modified later. Severity is high because bulk creation of containers could pollute the research database or consume storage resources, affecting data integrity and availability for legitimate research workflows.

From the tool's definition Tool name 'create_grid_container' indicates creation of a new container object. Sibling tools on this server (create_document_from_form, create_form, create_image_container, create_list_container, create_sample) all perform Write operations that create…
