It’s told to only use it if relevant because most people write bad ones. Someone should write a tool to assess CLAUDE.md quality.

If you can test how often it is being used by having a line in there saying something like “You must start every non-code response with ‘Woohoo!’”

It's always interesting reading other people's approaches, because I just find them all so very different than my experience.

I need Agents, and Skills to perform well.
