st: Testing equal skewness and/or uniform distribution across groups

Dear statalisters,
Is there any way to test equality of skewness across groups? whether
two samples are drawn from a uniform distribution?
I found several partial solutions - but what I actually need seems to
be something equivalent to -sdtest- applied to skewness instead of
variance.
Other partial solutions that I found is to use -sktest-. The problem
is that the test is applied to each group separately and not makes
comparison across groups
I also tried -ksmirnov-, but this test does not work very well on
small samples and it is not very helpful
I wonder if there is a better solution.
As always, your answers will be highly appreciated
