First, thanks to the langchain team for sharing your experience with claude code, I have read more that 5 times of this blog: https://blog.langchain.com/how-to-turn-claude-code-into-a-domain-specific-coding-agent/
And I learned and got a lot from this article. 
I also expect more about your summary、knowledge sharing、best practice for working with claude code, especially in web projects like front-end.
Thanks again. Best wishes.
