Behavior-wise, it does a lot more than the Codex CLI. The code of Codex is just of extremely poor quality. Just glanced, it looks like it uses at least two different HTTP server libraries (axum and tiny_http)! From quick check, rustc has 44 duplicate transitive dependencies (with different versions) while Codex has 109! And 2 dependencies are duplicated five times (in rustc the most duplicated are only three times)!

Like a human can, I suppose? Avoid extreme usage of generics. Avoid dependencies if not needed. Make sure you synchronize dependency versions to avoid duplicate code. Etc..
