WHY IT NEEDS A POLICY

Why put-document-domains needs a policy

This tool modifies document-level domain configuration, which affects how content is published and served across different domains/languages in Umbraco. While reversible, the change impacts content routing and multi-site configuration, making it a Write operation with high severity due to potential blast radius on content delivery if misconfigured across multiple domains.

From the tool's definition 'Updates the domains assigned to a document by Id' indicates the tool modifies existing document domain associations in Umbraco CMS. The verb 'Updates' confirms reversible data modification rather than deletion or execution of arbitrary code.
