A longer prompt is not automatically a better one

Add information because it fixes an observed failure or expresses a real requirement. Then remove one group of instructions at a time and run the same test set again. The shortest brief that still passes is the one worth keeping, because every extra instruction is something that can conflict with another one later.

This matters more than it used to. Current models follow instructions more literally than earlier generations, and vendors now advise stating each instruction once rather than repeating it for emphasis.
