 Contributors are requested not to use code assistants if they are not able to evaluate license of the code provided by an assistant, and to provide proper citation.

These pre­cau­tions include rig­or­ous test­ing, IP [(= intel­lec­tual prop­erty)] scan­ning, and track­ing for secu­rity vul­ner­a­bil­i­ties.
