## Why tags_update is rated Medium

This tool creates or modifies data reversibly by updating GTM tags. While updates are not destructive (they can be reverted), they directly alter tracking configurations that drive business analytics and marketing operations. The high severity reflects the blast radius: misconfigured tags can break analytics collection, misfire tracking pixels, or redirect user data inappropriately across multiple domains.

From the tool's own definition: "Tool name is 'tags_update' and description explicitly states '[WRITE] Update an existing GTM tag (read-modify-write)'."
