WHY IT NEEDS A POLICY

Why do_create_dns_record needs a policy

Creating DNS records modifies infrastructure configuration reversibly—new records can be updated or deleted later. This is a Write operation, not Destructive. However, DNS misconfigurations can cause service outages or enable DNS hijacking, justifying high severity. Confidence is 0.85 rather than higher because the description is empty, though the name and sibling tools provide strong contextual evidence.

From the tool's definition Tool name 'do_create_dns_record' indicates creation of DNS records. Sibling tools include 'cf_delete_dns_record' and 'cf_delete_zone', confirming this server handles DNS infrastructure modifications.
