Human Factors
Upon Arrival to ZZZ International Airport I called the B Flight Attendant and stated over the PA 'prepare doors for Arrival and Cross Check'. As soon as I went to the door I look through the peep hole and saw the gate agents eyes. I reach for the flap to open it up to pull up the two red levers and as soon as I reached for the handles the main handle started to lift up and I jerked back. I never gave the gate agent a thumbs up to say that the doors were disarmed and I never went to disarm the R1 door either. I watched the gate agent continue to pull the door and I looked at him and the floor and saw the bag deploy. I immediately called the FO and the Captain of what had transpired. Only the B flight attendant try to console me and informed me to take pictures and fill out an incident report immediately.
Flight Attendant reported that while preparing the doors for arrival; the gate agent opened the door before it was disarmed causing the slide to deploy.
