Why create_catalog_ui_policy is rated Medium
This tool creates UI policies that modify catalog item form behavior. While reversible (can be updated or deleted), it affects form presentation and validation rules across potentially multiple users. The blast radius is moderate—misconfigured policies could disrupt catalog workflows or expose unintended form fields, but the impact is limited to UI/configuration rather than data deletion or financial operations.
From the tool's definition 'Create a UI policy' indicates creation and modification of form configuration rules. The description explicitly labels it as '[Write]'.
