Hey (:
I found that using cursor without any extensions, works surprisingly well for me (except for class imports). My statamic instance uses antlers, and that also gets autocompleted really well, if your project already contains some references. I still installed the antlers-extension from stillat.
The only heads up I currently would point to is that cursor transmits hidden files to their servers by default 
Block access to credential files (*.env, *.env.local) to prevent AI exposure make sure to add your laravel envs to .cursorignore
