Der Teufel steckt im Detail — the devil is in the detail, and in German it is a warning rather than an observation.
Ins Detail gehen — to go into the detail, said approvingly of a discussion that is doing its job.
Gründlich — going to the ground of a thing, the standard German word of praise for work.
Schlampig, oberflächlich, husch-husch — sloppy, superficial, hurry-hurry. Three dismissals, all of work that stopped before the detail.
