WHY IT NEEDS A POLICY

Why update_campaign_bids needs a policy

This tool creates or modifies data reversibly—it updates campaign budget parameters without permanently deleting data or executing arbitrary code. While the blast radius is high (budget changes directly affect ad spend and campaign performance), the action is reversible (budgets can be adjusted again). This does not constitute a Financial transaction (no money moves directly) but rather configuration of spend limits.

From the tool's definition Tool name is 'update_campaign_bids' and description states it 'Update the daily budget for a campaign.' This modifies campaign budget settings in an advertising platform (Yandex.Direct via Click.ru).
