1. A shift tool, comprising:
a shifting system comprising a shifter arm;
sensors configured to generate measurement values when the shifting system is moved;
an artificial neural network trained to identify engagement of the shifter arm with a shifting feature of a sliding sleeve based on the measurement values generated by the sensors; and
a control circuit configured to:
extend the shifter arm at a first pressure for seeking engagement with the shifting feature of the sliding sleeve; and
responsive to the artificial neural network recognizing engagement of the shifter arm with the shifting feature of the sliding sleeve, extend the shifter arm at a second pressure for shifting the sliding sleeve
wherein the second pressure is greater than the first pressure.
