Ah yes, that's right. I actually turn off all of the cyclomatic complexity rules or set very high limits because I find those to be really annoying. So I mainly use RuboCop as a code formatter, plus some minor linting and style rules that aren't too obtrusive. I actually disagree with the parent article, and I've grown to really appreciate guard clauses. I find them much easier to read now.

VS Code will still highlight those cyclomatic complexity errors in the editor, so at least you will be able to fix them (or turn them off) without needing to wait for a CI build to finish.
