how can I add it to the bot so I can type !gag from my other mirc so the bot can gag a certain person?

on @*:TEXT:$($+($strip(!gag),*)):#: { 
  if ($2 ison #) && ($3 isnum) && ($nick isop #) silence $2 $3 
  else { .msg $nick Type: !gag <nick> <time in minutes> }
}
alias silence {
  describe # Hey $1, I think it's time for you to shut up. $&
    You've been gaged for $2 minute(s).
  if ($nick(#,$nick,+)) { mode # -v $$1 }
  if ($nick(#,$nick,%)) { mode # -hv $$1 $1 }
  if ($nick(#,$nick,@)) { mode # -ohv $str($$1 $+ $chr(32),3) }
  if ($nick(#,$nick,&)) { mode # -aohv $str($$1 $+ $chr(32),4) }
  mode # +b ~q: $+ $address($$1,2)
  var %i = $calc($2 * 60) | .timer 1 %i charge.timer $$1
}
alias charge.timer {
  mode # -b ~q: $+ $address($$1,2)
  if ($(% $+ $address($$1,2) $+ shoot,2) == 4) { mode # +v $1 }
  if ($(% $+ $address($$1,2) $+ shoot,2) == 3) { mode # +h $1 }
  if ($(% $+ $address($$1,2) $+ shoot,2) == 2) { mode # +o $1 }
  if ($(% $+ $address($$1,2) $+ shoot,2) == 1) { mode # +a $1 }
  .describe # $1 ok, you can speak again. Now stop talking like an idiot.
}

Note: Make sure the client running the code and people who command the trigger !gag are opped in channel.
