Why delete_location_custom_value is rated Critical
The tool performs a permanent deletion of data (a custom value) that cannot be undone. This meets the Destructive category criterion. Severity is high because deletion of location-level custom values could affect business processes, customer data integrity, or configurations relied upon by campaigns or workflows, with no easy recovery path.
From the tool's definition Tool name contains 'delete' and description states 'Delete a custom value from a location' — this is an irreversible deletion operation.

The rule that runs delete_location_custom_value safely

delete_location_custom_value is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
