This is the biggest issue I have by far with Cursor. It’s pretty frustrating to get a tab autocomplete suggestion and it looks right, so you accept, just to find out it used the wrong caps or added a suffix to a word. None of these words exist in my project, and Intellisense was actually showing the correct suggestion as I was typing. The models should definitely be applying a weight to what is in Intellisense, especially for tab suggestion that complete the actual line you are typing. Otherwise, I find myself snoozing cursor tab since I am faster just typing with Intellisense.
Not encouraging this issue has been around for 9 months and is still unresolved.
