I really think you mean "mediocrity" or "the quality or state of being mediocre" rather than "mediocracy" or "a dominant class consisting of mediocre people, or a system in which mediocrity is rewarded." I say this because you're trying to "give developers a code to live by that will increase the quality of code and coders." However, you're not talking about a "dominant class" or a "reward system." So I think the word choice is off.
