Proust was not a poet; he did not consider himself to be such, and he had no interest in these poems being published. But, here they are, for all to read. So, where does that leave us when we attempt an assessment? These poems are personal in nature; Proust intended them for the specific people to whom they were written, often playfully, often in haste, simply to scratch out the poetic content that floated across his mind. There isn't much of a sign that he crafted these poems with much intentionality, and the subject matter is too precise to be of much interest. Reading these poems is like reading inside jokes passed between lovers and best friends, they are full of inaccessible lines. One assumes Proust would be aghast at the idea that these poems were out there for mass consumption.
In reality, these are one star poems for the general reader, but were likely five star poems for their intended audience. There is nothing memorable in them for the rest of us, and no reason to ever reread and revisit these poems again, but the people Proust sent them to likely valued them very much. So, it's a three star review for me as I try to split the difference, but had I known more up front that Proust was not a poet, and that he did not take these poems too seriously, I'd likely have passed on this collection and stuck with his prose. Unless one is a completist of Proust's work, that's likely the best course of action.
