Haha. I always say that I'm only a good IC not because of my technical skills but because of my communication skills and my willingness to, as Steven Covey says, seek first to understand.

I literally got a transfer to a more exciting position and most likely a raise (discussing it on Tuesday =P) just because I communicated things related to the new position proactively and more than other people who, after the fact, expressed interest in the position.

Nice, congrats! A former boss once told me that over communication never hurt anyone. Of course there are ways to fine-tune and get the point across more succinctly but I think the point still stands - err on the side of over than under communication.

RTFM and being able to quickly reduce problems to the simplest possible test case are my superpowers.

To be fair, LLMs can be quite useful for quickly finding the correct place in TFM to look when you don't necessarily have a function or feature name to go on.
