From Game introduction:
A listing of archetypes of androids to be found in the world of Samurai Androids. However, the descriptions, Skills and weapons (attacks) should not be considered "complete" nor set in stone. Just like there are many styles of devices in our world, so it is in the world of the Samurai Androids. They are simply possibilities. Each Android will and should be unique. Modify as needed/desired, or create your own. (Community-created content welcome on the official Samurai Androids Itchio website discussion board.) Players should consult their GMs during Character Creation or before a game, just to be safe.
Attacks are not mentioned in the Core Rule per se, but they are not a new part of the game, just an alternative to weapons
