I'm still not sure how this is different than the vs code plugin. It seems to function in about the same way. Just uses a bit of different context reference. But that scope can easily lead to incorrect code targeting.
I haven't played with CW yet, but based on the screenshots and whatnot, it feels like CW adds another layer of requirements-gathering to its workflow (along with clear bullet points for what the terms of success look like) that regular Copilot doesn't have.
