WHY IT NEEDS A POLICY

Why send_email_notification needs a policy

The tool performs a write-class operation by creating and sending emails via SMTP. While emails are sent (not stored locally), this is a reversible side effect in the sense that subsequent operations can delete or suppress notifications.

From the tool's definition Tool name 'send_email_notification' and description 'Send email notification using Gmail SMTP' indicate the tool creates and sends email messages, which are write operations that modify external state (recipient inboxes).
