In the case of the Hilbert scheme of n points on X, the information comes
from the n-th symmetric power of X: https://arxiv.org/pdf/math/0304302.pdf

So, the input are X as an infinite-groupoid and the natural number n. The
output is the Hilbert scheme of n points on X as an infinite groupoid. I do
not know if there is some nice functoriality in this process which could be
expressed in HoTT in a natural way.  There are more results about the
Hilbert schemes it in Goettsche's homepage: http://users.ictp.it/~gottsche/

Kind Regards,
José M.
