WHY IT NEEDS A POLICY

Why send_gmail_notification needs a policy

Email sending creates new data (messages) in external systems irreversibly from the user's perspective, constituting a Write operation. Severity is medium because unsolicited or malicious emails could be sent to users, but it lacks the destructiveness of data deletion or the financial impact of payment operations. Confidence is reduced due to the uninformative empty description.

From the tool's definition Tool name 'send_gmail_notification' indicates sending/composing email messages to Gmail accounts. Email sending is a write operation that creates new messages in recipient inboxes and leaves a permanent record, though it is reversible (can be deleted).
