WHY IT NEEDS A POLICY

Why update_record needs a policy

Update operations modify data but are reversible (the previous state can be restored by applying another update). This is more severe than a Read operation but less severe than Destructive (which cannot be undone) or Financial (which moves money).

From the tool's definition Tool name is 'update_record' and description states 'Updates an existing record'. This modifies existing Salesforce data reversibly.
