## Why create-document-type is rated Medium

Creating a new document type in Umbraco CMS adds structural content to the system. While the action is reversible (the document type can be deleted), it modifies the CMS schema and configuration. This is a Write operation rather than Execute because it creates data structures rather than running arbitrary code or triggering external operations.

From the tool's own definition: "Tool description states 'Creates a new document type in Umbraco.' The verb 'creates' and the action of adding a new document type represents a data modification operation that is reversible (can be deleted)."

Risk signals: Admin/system-level operation
