The current rules are listed below:

• TallariumCredo.Checks.DefinitionOrder - functions should be ordered in a top-down fashion.
• TallariumCredo.Checks.Destructure - encourage a consistent use of Destructure
• TallariumCredo.Checks.EctoOnlyMacroSyntax - permit only the use of the macro syntax from the Ecto.Query module.
• TallariumCredo.Checks.NoRuntimeAccess - disallows runtime access to the specifid modules.
• TallariumCredo.Checks.NoSpecParameterNames - disallows the use of parameter names in the spec.
