Not setting arguments properly in rails tasks?

I am curious as to why my args variable is always coming back as {} in the following task:

desc "Create an Api Key assuming one doesn't exist."
task :create_api_key, [:name] => :environment do | t, args |
  if !ApiKey.find_by_application_name(args[:name])
    binding.pry
    if ApiKey.new(:application_name => args[:name], :api_key => SecureRandom.hex(32)).save!
      puts "Your key is: " + ApiKey.find_by_application_name(args[:name]).api_key
    else
      puts "Could not create the api key, you might be missing an argument: Application Name."
    end
  else
    puts "This application already contains an api key."
  end
end

The following is a run of the task (Note the binding.pry):

$ bin/rake create_api_key "xaaron_test"

From: /Users/Adam/Documents/Rails-Projects/BlackBird/lib/tasks/create_api_key.rake @ line 4 :

    1: desc "Create an Api Key assuming one doesn't exist."
    2: task :create_api_key, [:name] => :environment do | t, args |
    3:   if !ApiKey.find_by_application_name(args[:name])
 => 4:     binding.pry
    5:     if ApiKey.new(:application_name => args[:name], :api_key => SecureRandom.hex(32)).save!
    6:       puts "Your key is: " + ApiKey.find_by_application_name(args[:name]).api_key
    7:     else
    8:       puts "Could not create the api key, you might be missing an argument: Application Name."
    9:     end

[1] pry(main)> args
=> {}

Even if I do bin/rake create_api_key xaaron_test I get the same issue. What is going on? is there some small mistake some where I forgot about?

Update

I also spit out t to see what was in there:

pry(main)> t
=> <Rake::Task create_api_key => [environment]>

You pass arguments to a task by enclosing them in [] directly after the task name.

e.g.

rake create_api_key[xaaron_test]

If you use zsh, you need to escape the opening [

e.g.

rake create_api_key\[xaaron_test]
