I totally agree with you that this not the right way to start. But, in my experience, the more you use the tool the more of a "feel" you get for it, and knowing how all these different pieces work and line up can be quite useful (though certainly not mandatory). It's been immensely frustrating to me how difficult it is to find all this info with all the low-quality junk that is out there on the internet.

Isn't this article just another one in that same drawer?
> What actually belongs in CLAUDE.md - Write: - Import conventions, naming patterns, error handling styles
Then just a few lines below:
> Don’t write: - Anything that belongs in a linter or formatter config
The article overall seems filled with internal inconsistencies, so I'm not sure this article is adding much beyond "This is what an LLM generated after I put the article title with some edits".
