WHY IT NEEDS A POLICY

Why patch_template_text needs a policy

The name strongly suggests updating/modifying email template text content, which is a Write operation (reversible data modification). However, confidence is reduced because the description is empty, preventing verification of scope (e.g., whether it affects live campaigns or drafts).

From the tool's definition Tool name 'patch_template_text' indicates modification of template content. Sibling tools include 'build_email_template' and 'analyze_template', confirming this server manages email templates. 'Patch' implies partial, reversible updates to template text.
