WHY IT NEEDS A POLICY

Why subscribe_to_sequence needs a policy

This tool enrolls contacts into sequences/campaigns, which is a write/modification action that triggers CRM automation workflows. While it initiates automations, the enrollment itself is a reversible state change (contacts can be unenrolled). The blast radius is medium as misuse could trigger unwanted automated communications to multiple contacts.

From the tool's definition 'Enroll one or more contacts in one or more sequences or campaigns (automations)'
