If you just need to get a list of helper directories (without worrying about the language / tool to use) find is the command you need.
It can find anything in the directory tree.
If by immediate you mean that you only need child directories, but not the grandchild -maxdepth option will do the trick. Then -type will let you indicate that you are only looking for directories:
find YOUR_DIRECTORY -type d -maxdepth 1 -mindepth 1
