Hi,
from what I know /lib/capistrano/tasks/ folder is reserved for *.rake and *.cap files. That means capistrano tasks, not really helpers.
So I think you should be good by putting your helper methods in ./lib/capistrano/helper_methods.rb
Then in config/deploy.rb file:
```
require_relative '../lib/capistrano/helper_methods'
include Capistrano::HelperMethods
task :some_task do
helper_method
end
```
Hope that helps!
