NotPulex It's part of Wurst, no Baritone required. .path only shows you the path, .goto is the command that will actually follow the path. There is also .follow for following an entity, .protect which follows one entity while attacking others, AntiAFK which moves around randomly in a given area, and a few others. Unlike Baritone, Wurst's pathfinder can not only walk but also fly and will adjust its pathing automatically based on which hacks you have enabled.
For automated killing, look into FightBot (it uses the pathfinder only if you enable the "Use AI (experimental)" checkbox). For automated mining, look into either Excavator for quarry-style mining, or Tunneller for strip-mining (doesn't use the pathfinder, but works very well without it).
