"They are, in fact, one of the first races to encounter the cosmic threat as it heads toward the milky way galaxy," says Hickman on how the Skrulls get involved.
He continues on saying "After their crushing defeat in Secret Invasion, what we knew as the Skrull Empire was reduced to a series of fragmented, feuding territories run by regional warlords,One of those more prominent warlords is Kl'rt, the Super-Skrull, who features prominently in INFINITY.Some [Avengers] will look at working with the Skrulls as a necessity, the enemy of my enemy and all that. Others are much less accepting, like Spider-Woman."
