Everything seems all up to snuff for this PKGBUILD. Did you try building it in a clean chroot, I.E "pkgctl build"? The only real problem I could see here is that you might be missing a dependency or two since Coderabbit at least from the research I have done, does not say what their dependencies are.
Do not worry, this kind of discussion is appropriate on this mailing list, PKGBUILD reviews are a common thing especially from new AUR packagers.
