	if len(args) < 1 {
		fmt.Println("error") // so dry
		return
	}

may be you could Add same like annie -h etc, not just error

Nice catch! This is the code that was written at the beginning of this project and I forgot to update it when I finished the basic functions

@iawia002 Can I work on this issue?

[iawia002]

@arpit1997 Sure! About the error message, you got any suggestion?

[arpit1997]

@iawia002, In general, we show error (too few/many args) and the help that how to use and supported args. We can do same for this also

[iawia002]

@arpit1997 how about

too few args to call Annie

Use "annie -h" for more information

[arpit1997]

@iawia002, Can we just show them the help here itself? Because user have to type annie -h to see available commands. If he/she did enter too few/many args then we should show them the help directly.

[iawia002]

@arpit1997 cool!

too few args to call Annie

Usage of annie:
...

Will be doing the above. Will submit a PR by tonight. @iawia002
