WHY IT NEEDS A POLICY

Why update_bulk_sync needs a policy

The tool updates (modifies) bulk sync configurations within a data integration platform. This is a Write operation—changes can be reversed by subsequent updates. Severity is medium because misconfigured syncs could affect data pipelines and potentially cause unintended data movements, but the operation itself is reversible.

From the tool's definition Tool name 'update_bulk_sync' indicates modification of bulk synchronization configuration. Sibling tools include 'create_bulk_sync', 'delete_bulk_sync', and 'activate_bulk_sync', establishing this as a data pipeline management tool.
