A second assessment of substantial work, ideally from a different model and provider: does the document hold up? It checks facts, tests assumptions, and looks for gaps that would matter to the reader — helping a sound document succeed and showing what a weak one needs.
Asking a model to find fault with everything simply gives it another performance to deliver; asking for encouragement begins by congratulating you. Ask it to help the work by showing what holds up, what needs revision, and why.
