WHY IT NEEDS A POLICY

Why create-reply-draft needs a policy

This tool creates new email draft content and persists it to the Drafts folder, which is a reversible write operation. It does not send mail (which would be Execute-level), does not delete content (Destructive), and does not handle financial transactions. The 'draft' nature means it requires additional user action to send, making it clearly a Write category tool.

From the tool's definition Tool description states 'Create a reply draft to a mail message. Saves to the Drafts folder for review before sending.' The explicit purpose is creating/modifying draft content in the user's mailbox.
