View Source Credo.Check.Warning.MixEnv (Credo v1.6.7)

Explanation
Mix is a build tool and, as such, it is not expected to be available in production. Therefore, it is recommended to access Mix.env only in configuration files and inside mix.exs, never in your application code (lib).
(from the Elixir docs)
