Whenever I use an LLM I always need to review its output because usually there is something not quite right

… I've programmed for years in higher level languages professionally and never learned assembly and never got stuck because the higher level language was limited or doing something wrong. Whenever I use an LLM I always need to review its output because usually there is something not quite right. For context I'm using VS copilot, mostly ask and agent mode, in a large brownfield project.
