Nice job, one tutorial for this I actually understand :-)
But, where does the "sky_camera" entity go in the box? The middle or just anywhere in it?
If you want the skybox completely level with your geometry, you'll need to extend the walls downward, put a skybox textured floor under the regular textured floor, carve a hole inside of the regular textured brush (make a smaller brush, overlap it with the first one, and push Control+Shift+C) AND THEN put the sky camera level with the rest of the ground (kind of hard to explain lol).
