I've had a similar experience on huge codebases written entirely by an aI. It works for very very specific cases (e.g., Opus 5 has helped me with SIMD optimizations) but I wouldn't trust it to do a 10000 LoC project even with agents just because of the complexity problem and the shear amount of code I have to review. Or I'll have to change a bunch of things because the LLM made assumpts I didn't specify and it didn't ask about (e.g.: I have had to repeatedly tell these models to use std::atomic_flag and not std::atomic<bool> for a project I maintain because for some reason I cannot fathom, they love, love using the generic std::atomic<T> template, and they love using std::atomic<bool> where an std::atomic_flag would be better). Just little things add up, and before you know it I'm spending more time fixing it's issues than I am making progress.
