> at least half is comments or unit tests
Thanks, I see there's a slight (~50%?) overestimation there, but then again, even unit tests and comments in a target programming language count as syntactically correct code that needs to be evaluated and reasoned upon. I'm not that familiar with Rust's runtime introspection features, but in languages like Python, even the comments can directly affect code (e.g. `Foo.__doc__ = Bar.__doc__ + SOME_ANNEX`).

Many thanks! I've applied a fix—it's a single line added. The missing test is pending a runnable that invokes one of the forbidden syscalls. As I have no qualms about force-pushing around a repo that nobody forks, happy to credit you(r LLM) proper!

ocess can't overwrite existing .env files [1], but it could create a new $PWD/.env file, hoping to "escape" at next sandbox execution. That's a valid concern I'll have to think about some more.

I sometimes experience "Slirp not ready in time" [2], but it's due to a so far unexplained upstream issue [3]. I you have time/tokens to spare, I'd appreciate those PRs and further similar feedback!

Don't know whether it's a good idea. It sure has got its issues. But even as the SLOC count and the number of bugs metrics are proved correlated in literature [4], min SLOC is not the primary target—a reasonably graspable and stable composition of few dependencies is. Whereas overreliance on third parties nowadays often ends with a rug pull one way or another. We simply can't count on this "MXC" (...) to be maintainable/non-archived even a year from now, just when I'd get it all properly integrated and set up.

Oh, I certainly wouldn't like to limit myself to promoting just this repo! ^D^ HN is a good venue, lots of smart people around! I see everyone shilling their own sh** all the time. Often in green usernames. :shrug:
