Class name CamelCase (ARCH6001)

Key ruby.naming.class-name-camelcase · Severity warning · Category naming

In Ruby, class and module names must use CamelCase (each word capitalized, no separators). snake_case or underscored names violate the Ruby constant convention and hurt readability.

Incorrect

class user_account
  def initialize(name)
    @name = name
  end
end

Correct

class UserAccount
  def initialize(name)
    @name = name
  end
end

Fix

Name classes and modules in CamelCase; separate words by capitalization rather than underscores.
