Adding and removing verbs which can access mob's vars

(See the best response by Ter13.)
Code:
// So I want to have a verb which can access Player's mob vars
verb/something
    world << Stamina

// But how can I make it possible to access Stamina from:
mob/Player/var
    Stamina = 1000


Problem description: Is it correct way of thinking of it? I want to use verbs += /verb/something and it works untill I want to access Player's vars in that verb. Can I make this work or there is another way of doing this? Set hidden don't quite make it because they can use these verbs by typing them in or using macro.

mob/verb/Access_Variables()
    var input = input(src,"","") in vars | null
    world << "[input] = [vars[input]]"


If it's not this, is the path to the verb the same as what path the player(mob) is?

No, I want to make global verbs which I will at some point of the game add to Player's verbs by using verbs += /verbs/something. It works for like
// global space
verbs
    Test()
        world << "test"
        // But I want to access here things like Taijutsu of the player

mob
    Player
        verb
            Rest()
                if(Taijutsu > 10)
                    verbs += /verbs/Test

Alright, I understand the problem you are running into.

usr is typecast as /mob, not /mob/Player

You will want to create a variable that typecasts usr into the expected type.

// global space
verb
    Test()
        var/mob/Player/user = usr //this is called typecasting
        world << "test"
        // But I want to access here things like Taijutsu of the player
        world << user.Taijutsu //works use this one
        world << usr.Taijutsu //doesn't work
        world << usr:Taijutsu //works, but is unsafe

mob
    Player
        verb
            Rest()
                if(Taijutsu > 10)
                    verbs += /verbs/Test

Also, I thought I'd throw in another option, which is syntactically correct, but in terms of polymorphism is incredibly stupid.

Most DeeBeeZee/Nartolo/Breach rips handle their hidden verbs like this:

In my case, you have to waste two instructions performing casting in order to access usr which is theoretically just a src alias if you ignore the fact that the type structure on global verbs makes src null.

There's another option, which is to define an uninstantiatable subclass of /mob/Player to house verbs that are hidden from /mob/Player by virtue of being downstream of the inheritance chain.

mob
    Player
        var
            herp
            derp
        verb
            add_test()
                verbs += /mob/Player/_verbs/verb/test
                verbs += /mob/Player/_verbs/verb/remove_test
                verbs -= /mob/Player/verb/add_test
        _verbs
            verb
                test()
                    world << herp
                    derp = herp
                remove_test()
                    verbs -= /mob/Player/_verbs/verb/test
                    verbs -= /mob/Player/_verbs/verb/remove_test
                    verbs += /mob/Player/verb/add_test


Again though, typecasting is a better option than adding a dummy subtype to act as a verb collection.
