Why create-document-blueprint is rated Medium
The tool creates new data structures (document blueprints) within Umbraco CMS, which is a Write operation. Creation is reversible through deletion. Severity is medium because unauthorized blueprint creation could pollute the content structure and require administrative cleanup, but lacks the irreversibility of Destructive operations or the financial impact of Financial operations.
From the tool's definition Tool name 'create-document-blueprint' and description 'Creates a new document blueprint' indicate data creation in Umbraco CMS. Document blueprints are templated content structures, so this creates new reversible content objects.
