Code Explanation:

There are 3 types of things to auto-complete:

1. command: the command itself
2. parameters: command parameters.
3. options: command options

Here's an example:

mycli hello name --from me

* command: hello
* parameters: name
* option: --from

When command parameters are done processing, the remaining completion words will be options. We can tell that the command params are completed based on the method arity.

## Arity

For example, say you had a method for a CLI command with the following form:

ufo scale service count --cluster development

It's equivalent ruby method:

scale(service, count) = has an arity of 2

So typing:

ufo scale service count [TAB] # there are 3 parameters including the "scale" command according to Thor's CLI processing.

So the completion should only show options, something like this:
