Came here to point this out.

I don't think the author understands that every single API call to Claude sends the whole context, including prompts, meaning that all this extra text in CLAUDE.md is sent over and over and over again every time you prompt Claude to do something, even within a given session.

You're paying this disproportionately-huge amount upfront to save a pittance.

If you were Claude you would have no emotions or thoughts about a prompt one way or another
