We use SonarCloud’s built-in quality profiles to set the same rules guide for the whole organization. Ideally, all projects will be measured with the same profile for any given language.
To see the rules of the supported language, see Quality Profile menu on SonarCloud.
In the meanwhile, you can also refer to Google Style Guides for more style guidelines to follow. If you may find any rules is major but is not included in the SonarCloud’s built-in collections of rules, raise an issue to let us know.
