Please, please - just link to the actual "CUE" project. Not everyone has heard of your favourite thing. The first reference to `CUE` should be a hyperlink.

For other people: I'm pretty sure the author is talking about https://cuelang.org/

Is there anyone out there that has actually, in the real world, realized CUE's promise of bundling type safety + data/configuration + task running in such a way that does not require wrapping it in shell scripts? Can you set up your CI/CD pipelines so that it's literally just invoking some cue cmd, and have that cmd invocation be reasonably portable?

The problem is, once you have to wrap CUE, the loss of flexibility within a special-purpose language like CUE is enough for people to ask why not just bother writing the scripts in a general purpose language with better ecosystem support. And that's a hard sell in corporate environments, even ones that find benefit in type safe languages in general, because they can just pick a general purpose language with a static type checker.
