See https://www.klipper3d.org/G-Codes.html for the complete set of Klipper gcode commands.

Your slicer takes a CAD model and “slices” it into layers, outputting the instructions, as gcode, necessary to control the printer to print each layer. These gcode instructions specify tool path movements and control all operations.

Klipper's goal is to implement a minimal set of the most common of gcodes required to be effective, and to leverage macros to build more complex instructions from smaller building blocks, and preferring “extended gcode commands” that are more human readable to traditional Marlin or RepRap gcodes designed when simple parsing simplistic was a necessity during to hardware limitations for the firmware of the time.
