Can't agree with the formula for performance, on the "/ size" part. You can have a huge codebase, but if the complexity goes up with size then you are screwed. Wouldn't a huge but simple codebase be practical and fine for AI to deal with?

The hierarchy of leverage concept is great! Love it. (Can't say I like the 1 bad line of CLAUDE.md is 100K lines of bad code; I've had some bad lines in my CLAUDE.md from time to time - I almost always let Claude write it's own CLAUDE.md.).
