I trust it more with Rust than Python tbh, because with Python you need to make sure it runs every code path as the static analysis isn't as good as clippy + rust-analyzer.
I think the excellent error messages in Rust also help as much humans as it does LLMs, but some of the weaker models get misdirected by some of the "helpful" tips, like some error message suggest "Why don't you try .clone here?" when the actual way to address the issue was something else.
