Ahh, I wasn't sure if it did or not, I told the model the file directly in my example "Edit file ABC.php to do..." so I wasn't sure if had that context or just found the file (I also had that file open).

I really do hope they improve this further. Junie (Jetbrains Agent) has much nicer UI. I'd love Claude code with more native UI.

in addition to the diff viewing, the plugin also allows claude code to pick up more context from the IDE!

it should automatically pick up your current selection, as well as any highlight/diagnostic errors (squiggly errors and warnings) that the IDE finds. there's also a shortcut key (Cmd+Option+K) to send your current selection as a @File reference to the prompt.
