Could someone explain to me in very simple terms how to access tag values out of the hook @args?

For example:

I want to retreive the CategoryID as a scaler (integer), which is avaliable in a lot of templates, including browser_info.html.

my (@args) = @_; <- all hooks seem to have this in as default, why not $args???

my $args = shift;

my $cat_id = $args->{CategoryID}; ???

No matter what I try, including $tags = shift; I get an error about value not being a hashref and equalling "1".
