Video is not a single image. It requires sampling frames, transcribing the audio, and tying
         events to time. A system may answer from the audio and ignore what appeared on screen,
         or the reverse. Specify whether the requirement is to summarize the dialogue, extract visual

         events, or find a clip, and ask for a timestamp with every important result.

         With data and tables, do not make a language model a substitute for a calculation tool. Use
         it  to  understand  what  is  required,  to  write  code,  and  to  explain  the  results,  while  the

         computational tool performs the operations. With code, ask for tests, edge cases, and the
         runtime environment, and do not rely on a single successful run. With presentations, test
         the sequence, the accuracy of the figures, image rights, and whether elements can be edited,

         not only the beauty of the slide.
