I think chimps that strip branches off twigs, wet the stalk with saliva to make it sticky, and then stick the stalk down ant holes to get ants to stick to the stalk so it can get at them exhibits quite considerable planning as well as repeatable implementation.
I am not sure if the chimp brand of planning is really that different from the planning involved with the first manufactured stone tools.
