WHAT IT DOES

What draft_gmail_email does on VaultAssist

AI agents use draft_gmail_email to create or update resources in VaultAssist, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your VaultAssist environment.

RISK

Why draft_gmail_email is rated Medium

This tool creates email drafts, which are reversible modifications to user data. It falls under Write rather than Execute because it does not trigger external operations (sending emails), and it is not destructive since drafts can be modified or deleted.

From the tool's definition Tool name 'draft_gmail_email' and description 'Create a draft email using Gmail API' indicate creation of email content. Drafts are reversible (can be deleted or modified before sending), and do not constitute actual message transmission.
