It is based on pure vibe coding, where the user literally has no idea what's being produced.
After having understood the context, I still believe that a strongly typed language would be a much better choice of a language, for exactly the same reason why I wouldn't recommend starting a project in C unless there is a strong preference (and even then Rust would probably be better still).
LLMs are not perfect, just like humans, so I would never vibe code in any other environment than one in which many/most logical errors are by definition impossible to compile.
Not sure if C is worse than python/js in that respect (I'd argue it is better for some and worse for other, regarding safety) but Java, Swift, C#, Go, Rust, etc. are great languages for vibe coding since you have the compiler giving you almost instant feedback on how well your vibe coding is going.
Claude Code is pretty good at Rust, but it works best if there's a pre-existing structure built by a human that it's operating within. Rust's error messages give rich context and are designed for humans, so it's able to figure out how to resolve its mistakes from them in ways that it simply would have to grind through in tests with trial and error in dynamic languages. And then when you do write unit tests to address logic bugs, it's able to leverage the rich context from the type system to write decent tests.
I wouldn't trust it to reliably write safe C though. It works in Rust because there's meaning embedded into the types that are checked by the compiler that gives it feedback when it makes mistakes. But you don't get that in C.
