I'm not going to argue whether code is the most important or not, but I will claim that if you cannot write working code you are not a developer. And if you cannot use the standard library of your language, then you cannot even get to hello world. It doesn't matter how good you are at communicating then. You can perhaps be a "rockstar" in a very specific niche e.g. scripting or customizing inside some vertical platform which is fully localized. Those do exist. But show me the mainstream language where the standard library API have been translated to a non-English language. Another example might be working completely without third-party libraries. Again this would be possible but a very niche scenario in this day and age.
