Be friendly and ask questions. Your teammates might be happy to spend a little extra time going into extra details if you are curious. You will sometimes uncover design flaws and knowledge gaps in the team by doing this. Look for ways to make the code, architecture, tooling, and processes better, and present those as possible avenues for the team to consider.
