Why update_records needs a policy

This tool modifies data (UPDATE operation) but does not delete or destroy it, making it a Write operation rather than Destructive. The severity is medium because misuse could corrupt or alter important data, but the changes are theoretically reversible through backups or additional updates. The confidence is high because the intent and function are clearly stated in both name and description.

From the tool's definition Tool name 'update_records' and description 'Update records in a table based on specified conditions' explicitly indicates modification of existing data in reversible manner.
