There is no alignment, there is no sharing of rule files or other instructions. These are tools no different then an ide which people are also free to choose so why would we?

Also rule files and other "memory sharing" are crutches. If it's that important just put it in your readme or other documentation and the LLM can get the context from that just like your teammates.

Plus isn't it a little silly this extremely well capitalized companies can't figure out how to get an LLM to follow a readme effectively and instead wave it away by saying you need to now maintain yet another thing?
