I have been a Claude Code user for a while now, but thought the 7 day challenge would be a useful exercise in more firmly embedding the ideas. I built the newsletter, and my first topic was about the OpenAI Proposed "Robot Tax" - One thing I learned: Since I am a daily user, I actually just realized how much better Claude Code has gotten. Understanding all of the credentials helps a ton with speed, but what I built today would have taken a weekend 6 months ago. - One thing you'd improve: I woud spend more time up front really defining the outcomes I want. The end result was really good, but I could have built this using brand guidelines, voice, and potentially a component that split the output into reuable assets on different platforms. I also used this to test the new GPT Image model API, and the results are quite good!
