WHAT IT DOES

What delete_gmail_label does on VaultAssist

AI agents call delete_gmail_label to permanently remove resources in VaultAssist, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_gmail_label is rated Critical

Deleting a Gmail label irreversibly removes a label object that may be in use by multiple emails and filters. Unlike reverting a modification, label deletion cannot be undone and impacts email organization and automation. This qualifies as Destructive rather than Write.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a Gmail label' — this is an irreversible operation that removes organizational structure and potentially affects message grouping and filters.
