WHY IT NEEDS A POLICY

Why api_policy_apply_outbound needs a policy

The tool creates or modifies API policy configurations on live API Manager instances. While the change is reversible (distinguishing it from Destructive), it directly impacts API behavior, security controls, and traffic handling. An unintended policy application could disrupt API functionality, introduce security gaps, or cause unexpected routing/filtering changes.

From the tool's definition 'Apply an outbound policy' to API instances modifies API configuration by adding or updating policy controls. This is a reversible change operation (policies can be removed via api_policy_delete or api_manager_remove_policy).
