RISK

Why sendDraft is rated Medium

This tool modifies state by sending a prepared message, but does not irreversibly destroy data or cause financial harm. However, it does trigger an external communication with potential side effects (message delivery to recipients), making it more than a simple data update.

From the tool's definition Sends an existing Gmail draft, which is a reversible write operation. The message moves from Drafts to Sent folder—data is transmitted but not destroyed, and the action is technically reversible (the sent email can be deleted or unsent where supported).
