Does Project Rules works with other files? How to create autocontext?

Do Project Rules mention works with other files?

I understood that if we mention .mdc then it will work but can we mention other files?
I added rules like this:

  • Always use @UiTypography.tsx for text nodes - it seems to be working but hallucinates with props sometimes
  • Always use these colors @colors.scss - it seems like it ignores the content of the file

If it doesn’t work, how can we provide additional context without repetitive mentioning?
