getting the same - it looks like its inside the cells?

No, but I also get

poly overlap of poly contact < 0.08um in one direction (licon.8a)

.

@tgingold: Which cell(s)?

At least in clkdlybuf4s15_1 I also get

Poly resistor spacing to diffusion < 0.48um (poly.9

when tapvpwrvgnd_1 is just on the left side of a conb_1

I believe that I may be using the wrong type of poly resistor in that rule, which means any such rule is a false positive. I'm going to look into it now.

Ok, I won't use that cell. Weird!

@tgingold: I just posted a corrected version of the GDS for that cell in github skywater-pdks issue #261.

Great!
