AI agents call ppt_delete_table_column to permanently remove resources in Ppt — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of table columns is an irreversible operation that destroys data structure and content. While the blast radius is somewhat contained to a single presentation element, the operation cannot be undone programmatically and constitutes destructive data modification. This is categorized as Destructive rather than Write because it permanently removes structured data rather than reversibly modifying it.
From the tool's definition The tool name and description explicitly state 'Delete a column from a table,' which removes data irreversibly from a presentation table.
