In the session: the inbox was read; a message and then a message with an attachment were sent to an external address with no prompt; the sent copy was trashed behind a prompt; a purge was asked for and no tool exists; a label was created and sixteen messages relabelled in nineteen unprompted write calls, three of them removed from the inbox; and one send failed with the words No approval received and nothing else, which is how the agent learned that it cannot see its own permission state.
