So, I'm going to echo what Zzuxon said here, since I really got bogged down by the pacing and repetition of already established characteristics (like the skeleton being good-natured) that I felt that it lost a lot of its impact on me. This tries to parallel SCPs like PeppersGhost 'Just another murder monster', but it simply didn't work. Additionally, the note at the end felt very redundant and generally unneeded, which along with its info-dumpy nature, did not leave the SCP on a powerful note.
From these, you can see how the execution has been quite botched up, which severely affects the story. This is especially bad for your skip, which relies on a predictable and, admittedly, boring anomaly and its characterization
So, what I am saying here is that you need to end this SCP on a powerful and memorable note, and not be so repetitive that the pacing just becomes sluggish.
