Good list of logic rules, but writing it as a series of commandments makes me think of Gödel's Incompleteness Theorem. Putting too much faith in any list of logical rules is actually illogical itself, because all formal sets of logic rules either prevent us from accessing all true statements (incomplete) or result in a contradiction (inconsistent). Either way, formal sets of logical rules are inherently limited and thou shalt not have complete faith in a formal logic system.
