View Source Credo.Check.Consistency.UnusedVariableNames (Credo v1.6.3)
This check has a base priority of high and works with any version of Elixir.
Explanation
Elixir allows us to use _ as a name for variables that are not meant to be
used. But it’s a common practice to give these variables meaningful names
anyway (_user instead of _), but some people prefer to name them all anonymously (_).
A single style should be present in the same codebase.
Check-Specific Parameters

:force
Force a choice, values can be :meaningful or :anonymous.
This parameter defaults to nil.
