Why delete_collection_folder is rated Critical
This tool removes data that cannot be recovered without external backups. While the blast radius is somewhat limited to a single folder within a Postman collection (not affecting live systems or other collections), the deletion is permanent and could disrupt API testing workflows if misused by an AI agent without proper safeguards. Classified as Destructive rather than Write because the action is irreversible.
From the tool's definition Tool name 'delete_collection_folder' and description 'Delete a folder from a collection' explicitly indicate irreversible deletion of a collection folder and all its contents.
