Tosafot Yom Tov
AN EYE THAT SEES, AN EAR THAT HEARS, AND A BOOK IN WHICH ALL OF YOUR DEEDS ARE WRITTEN. Some things the eye sees, such as the deeds of the wicked, and some things the ear hears, as in the cursing of the profane, so the mishna says both an eye that sees and an ear that hears. And so that one shouldn’t think that anything which comes before His great throne is forgotten, the mishna says “and a book in which all of your deeds are written.” This “book” and “the book of rememberance” that the poet mentions in the liturgy for the Days of Awe63In the liturgical poem Unetaneh Tokef. are one and the same. This usage also appears in the Torah: “from the book you have written” (Exodus 32:32), “I will erase him from my book” (Exodus 32:33).
To prevent one from sinning, it would have sufficed for the mishna to instruct one to consider the fact that all of one’s deeds are written in a book, which would obviously only be for the purpose of doling out reward and punishment for those deeds. The previous phrase, that there is One who sees and hears, was put in because in its absence the following metaphor would be unclear to the listener. Maharal writes in Derech Chaim that the mishna uses the singular—“an eye that sees, an ear that hears”—to emphasize that G-d is not a man that he should have eyes of flesh and blood, G-d forbid.

Rambam
The eleventh principle is that God, may He be blessed, gives reward to the one who does the commandments of the Torah and punishes the one who transgresses its prohibitions and that the great reward is the World to Come, and that the strong punishment is being cut off. And we have already said about this matter that which will suffice. And the verse that indicates this principle is that which is stated (Exodus 32:32), "And now, if You will lift up their sin; but if not, erase me please," and God, may He be blessed, answered him (Exodus 32:33), "The one who sins against Me, I will erase from My book" - this is a proof that He knows the servant and the sinner to give reward to this [one] and punishment to that [one].
Da'at Zekenim
ואתה לא הודעתני, “and You have not informed me;” Moses means that not only did G–d not inform me of details about the angel which He had said that He would send to walk ahead of the Jewish people (Exodus 32, 34) ; it is not only that You Yourself will not walk in front of us, but You did not even name the angel You have assigned for this task. We are now no better off than any human being on earth, each one of whom has an angel walking in front of him. (Compare Psalms 91,11) where David refers to this with the words: כי מלאכיו יצוה לך לשמר לך בכל דרכיך, “for He will order His angels to guard you wherever you go.” Seeing that this is so, how do I benefit from Your having told me that I have found favour in Your eyes? Even Avraham’s servant, Eliezer, had been assured of the same kind of angel, without having been told by G–d that he had found favour in His eyes? (Compare Genesis 24,7)
