Good stuff! Looks neat on first impression. One question: when I suggest an improvement to the code it created, it further edits the code but the original edit goes away. (I asked it to safely access a variable's property in the suggested code - it changed the code to adhere to it but now it only handles that and doesnt show the other code it added earlier. HTMS)
Good luck! Having used JetBrains IDEs (PHPStorm mostly) for what a decade(?) using VS code based editors like Cursor and Windsurf feel a step backward in spite of the AI, because the intellisense isn't there.
If you can get something that works inside JetBrains as well as these AI editors then you're in a "Take my money" position!
At the moment apart from your lack of support for PhpStorm your privacy policy wouldn't pass muster here, and I see no choice available on the models to use? E.g. Claude 3.5/3.7 or Gemini.
