Works mostly fine for me on Rust backends. As long as I'm willing to accept tight contracts at the edges with spaghetti in the middle, or otherwise gate approval for everything it does.

If I want good abstractions, sure, I can set up approvals and babysit it with reprompting, because it will do stupid things that an experienced engineer wouldn't. But the spaghetti also works in the sense that it takes the input types and largely correctly maps them to the output types.

That doesn't emarrass me with customers because they never see the internals. On front-end, obviously they will see and experience whatever abomination it cooks up directly.
