If the intent is to check, then thats what the magic will do. Its about intent. If you intend for an effect that is overt and strong enough to provide you with a means of checking, then thats what you will get. Just be prepared to be freaked out, or your own mental weakness will be an inhibitive effect.
I get it! I finally get it! It took being sent to Limbo('s ignore list) to finally reach the epiphany. Oh my goodness, it's so beautiful! It makes so much more sense now! I have to explain it to you, it's so mighty and powerful!
Here it is: Limbo lives in a version of Matrix or possibly Discworld. I know it doesn't make much sense at first but hear me out.
If it's the matrix (which I like to call psychosomatrix) it all makes sense, since, you know, it's not the reality that changes but your perception of it and your perception of reality shapes the reality itself. There's no spoon, indeed, and Limbo is The One!
Or, alternatively, there really is spoon, and fork, and certainly a knife and dishes, else we wouldn't have a kitchen and place where to be. In that case, Limbo is some kind of wizard. And, as Sir Terry Pratchett so eloquently put it in his "Science of Discworld, the Globe", wizards first evolved the wish then designed a command. And it works, because its Discworld.
On Roundworld, the wizards had to observe the reality and find how it works, not to change the laws of physics by mere thought. And since we live in this reality, the only explanation is that Limbo has found a way to manipulate matter with his own thoughts, thus making him Avatar of the very God. And that is testable hypothesis, so just test it and give the man Million Dollars right now!
