Send one plain-text email from the connected Gmail account. The host must obtain fresh explicit approval for every call and show the exact to, cc, bcc, subject, and complete body. A response lost after dispatch has an unknown outcome and must never be retried automatically.

Create one Gmail user label by exact name. This is an external write; it does not apply the label to messages or threads.

Update one Gmail user label resolved by its exact current name. This can rename the label or change its Gmail visibility settings; it does not modify message membership.

Permanently delete one Gmail user label resolved by exact name. Deleting the label removes it from every affected message and thread, so the host must obtain explicit consequence-aware approval.
