Looks like quite shoddy code though. Like, the procedure for running a shell command is pure side-effect procedural code, neither returning the exit code of the command nor its output. Like the incomplete stackoverflow answer it probably was trained from. It might do one job at a time, but once this stuff gets integrated into one coherent thing, one needs to rewrite lots of it, to actually be composable.

Though, of course one can argue, that lots of human written code is not much different from this.
