Removing a label modifies the state of a Gmail message (e.g., archiving, marking as read, unstarring) but is generally reversible — labels can be re-added. This is a metadata modification, placing it in the Write category. Misuse could cause messages to be inadvertently archived or marked read at scale, hence medium severity.

From the tool's definition Remove a label from a Gmail message. Common uses: remove UNREAD (mark as read), remove INBOX (archive), remove STARRED (unstar).
