Just to add an explanation here, it looks from the screenshot that @janswist hit the Quick Question button / shortcut.
In this feature, we tell the AI it cannot write any code, and can only reply with a text answer to whatever question the user may ask.
Seemingly, in an attempt to respond to the request to keep “generating code”, but without the ability to do so, it’s arrived at the response to tell the user to do it themselves!
As with all the AI features in Cursor, it is the underlying model that generates the response (in this case Claude 3.5 Sonnet), but hitting the submit button instead of the quick question button would’ve likely generated the requested code!
