I recently tried out Copilot with Sonnet to implement whole C++ headers into .cpp files and it did very well making the implementation consistent, readable, and easy to reason about. Not having much C++ experience, it made the whole process much easier - some memory/etc errors in my own code would have been intractible to fix without it. It was also fantastic at turning a postgresql implementation file of that header into an sqlite implementation that worked/passed tests on the first try.

Overall, it seems like defining the structure to some extent yourself and letting the agent fill in implementation and suggest architecture changes is a good way to go to get a lot of useful work out of it without letting the structure of the overall app run away from you.
