They're not about Claude or GPT. They're about CLAUDE.md.

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
