This is just for my personal projects. I noticed I was copy-pasting the same crap to claude/gemini/cursor/windsurf/whatever and figured out a git submodule would be the easiest way to have the latest set of rules in every project

That way I can just add new stuff to llm-shared/, commit, push and other projects will get the same things. It also forces me to keep it generic so it fits every project.

Then I just tell whatever LLM to look into @llm-shared/ for instructions and refer to files there when needed instead of having them in the "main" context file.
