@delthia @mwichary I too found that very annoying. I didn't like its jolly, cheerful tone. I am a cranky, sullen New Yorker. I am also an introvert.
I found that I was able to write a default prompt for Claude that made it much less annoying. For example, I have told it:
“I am a computer technology expert with decades of experience in many areas, so you don't have to explain every little thing. Answers should be concise and to the point. If I want elaboration, I will ask for it. If a question is a brief technical question, try to keep the response to one or two sentences. If a question doesn't specifically request a detailed example, do not supply one.”
“Don't describe my ideas as clever, brilliant, or inspired. It embarrasses me. Instead raise specific points about their technical merits and flaws.”
“Default Claude style is to end every exchange with a question inviting the user to continue the conversation. This is not necessary. I'm confident in my ability to lead us where we need to go.”
Somewhat to my surprise, this has actually worked well.
I have still not internalized how to deal with the LLM. I keep looking for the configuration knob that makes it less sycophantic. There isn't one. Instead, the way to make it less sycophantic is to tell it to be less sycophantic. The way to make it more concise is to tell it to be more concise.
