WHY IT NEEDS A POLICY

Why update_product needs a policy

This tool modifies product data within the Directus CMS but does not delete, destroy, or permanently remove information. Updates are typically reversible through version history or subsequent corrections. The scope is limited to product entity modifications, giving it medium severity—an agent misusing this could alter product prices, descriptions, or metadata, causing business issues, but the changes can be undone.

From the tool's definition Tool name 'update_product' and description 'Update an existing product' explicitly indicate modification of existing data in a reversible manner.
