WHAT IT DOES

What update_site_utm does on Webcake Storefront

AI agents use update_site_utm to create or update resources in Webcake Storefront, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Webcake Storefront environment.

RISK

Why update_site_utm is rated Medium

UTM links are configuration data used for tracking and analytics. The 'update' operation modifies existing data reversibly without deleting it or executing arbitrary code. This fits the Write category (creates or modifies data reversibly). Severity is medium because incorrect UTM parameters could affect analytics tracking and reporting, but poses no direct financial, destructive, or execution risk.

From the tool's definition Tool name 'update_site_utm' indicates modification of UTM (Urchin Tracking Module) link parameters. Description states 'Update a UTM link' confirming reversible data modification.
