No. There is one important distinguishing characteristic which separates the above from a spell system. In athe above cases, the assumption is that successfully tumbling, fast-talking, sneak attacking, or chopping something with a sword does not prohibit the character from doing it again. In fact, whenever you assume a naturalistic explanation for events, the assumption is that doing something once indicates that it can be done again.
There's nothing intrinsic to the concept of a spell system that limits the number of times per day you can cast a spell. That's just something D&D imposes. In GURPS, Fantasy Hero, or even D20 variants like Sovereign Stone, spells can be recast. If a limit on uses per day is some sort of criteria for qualifying an ability as a spell, does that mean these aren't actual spell systems? It does not.
If you have a natural talent for doing something, what should forbid you from doing it whenever you like - or at least more times per day than can be easily tracked?
In the case of the Hunter, he has to study the battlefield, which seems like a pretty mundane explanation.
The one case in the above that doesn't seem to fit into the others is the barbarians 'rage' ability. Why can the barbarian only get angry once per day? Balance reasons. The barbarian's rage ability could just as easily be a spell-like effect because it is not at all clear that it isn't some supernatural ability on the barbarian's part.
It's marked as an extraordinary ability, which makes it very clear that is not a magical ability.
A few times a day the barbarian gets to call on supernatural forces. OK, that's magical so I don't need a naturalist explanation for why it can only occur a few times a day.
You don't, but it would certainly make the barbarian tremendously unappealing to other players. It could be described as supernatural, but is not. He can't rage whenever he feels like it because of physical and/or mental fatigue. That is as simple an explanation as magic.
But what is the naturalist explanation for only being able to make better use of cover a few times in a fight? I mean, if you can make superior use of cover once, why are you suddenly unable to make superior use of cover latter?
Because it gets harder to do. Call it mental exertion, stress whatever. The higher-level hunter is mentally more resourceful than the lower-level hunter. After all, characters do level up by a mechanic called "experience". It's funny We get used to the notion that experience equates to upgrades in raw power, but experience is pretty much a mental attribute.
The token system seems to encourage a explaining the situation in a way that fits the mechanics to a degree beyond what we are used to in D&D. Normally, if you had 'Improved Duck Behind Cover' then you'd just be good at crouching behind cover. Now though, the character spends his ability to crouch behind cover as a resource. "Ooops the goblin steps 6" to the left and you are completely out of ideas on how to stay hidden... at least until the sudden beginning of the next encounter."
Precisely. He's run out of ideas. His bag of tricks is empty. Maybe if he had more experienced, he'd have another back-up plan.
Only in a system that let's you raise dead at will.
That seems like an arbitrary reason for saying that raising the dead is not magical. Deities can raise the dead at will. That's not magic? A warlock's eldritch blast is usable at will. That's not supernatural?
