AI agent run animation: a prompt sent and answered with visible tool steps. A prompt typed, sent, and answered by an agent that shows its work. A composer opens, a request types itself into it under a colour wave that rides the caret — the last dozen characters run accent into ink behind it — and a round button appears when there is something to send. The shot cuts in close on that button: one frame, 1.9×, with no intermediate value anywhere in the recording, because a zoom onto a button the viewer has watched for four seconds says nothing. A pointer climbs to it and stops dead for three frames before it presses, the field floods, and a second cut hands the frame to the run — a dotted rail with one step lit at a time, each arriving from below, typing two lines about what it is doing, and passing the frame on at a measured 31.4 frames. The composer's scale came off the card's own sub-pixel width, whose edge is five levels of luminance and needs a derivative rather than a threshold; the step cadence off the frames each title's accent burst begins. The field's wash and bloom were fitted to sixteen samples across the frame.
