Specifically: why people write a CLAUDE.md file, follow online guides, and still get the same frustrating result — Claude ignoring half of what they wrote, repeating the same mistakes, requiring constant re-prompting. So I started AI Architecture Weekly — a free newsletter, every Monday, for senior devs who use AI daily and want depth instead of hype. The first issue, out today, is about the five CLAUDE.md mistakes I see most often when I review production codebases: Treating CLAUDE.md as a prompt Listing rules without context Skipping the project map Generic patterns instead of project-specific ones No "things that broke us" section Each one is something that cost me hours before I learned to spot it. The full issue has concrete code examples and the fix I use now.…
