Nice. These version changes (tailwind v4, nextjs app router, etc) are now more painful when I use LLMs for coding, because pre-training won't know anything for like a year.

Cursor rules is nice, but can I also use those in Claude projects or ChatGPT? Haven't tried it, maybe it works?

I want a tool-agnostic text file that can "upgrade" any LLM's context to say "use this new version, not the one you were trained on"
