Finally got a home and am finding the same thing here in central Texas. At least with the crap soil the builders use to form the land around the foundation. My plan is to attempt to grow more deep rooted plants so their roots can break up the soil and die off when I trim them. Then aeration and topsoil composting. Still a work in progress so I have no idea if it'll work.

The clay soil usually has a low organic matter content. So bringing mulch, grass clippings etc. does improve several key factors for the plants to thrive. The problem with putting a layer of rotting grass/weeds on the top is that at least in some locations it will make a perfect slug/snail farm. So I prefer to burry it in shallow pits/trenches. Also probably any preferably dense plant cover protects the top layer from being backed by the sun and becoming brick-like.
