Suggestion Add args for the commands

Why don't you add args for the commands ?
For example using this code:
​

PHP:

declare(strict_types=1);
namespace pocketmine\command\defaults;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\utils\InvalidCommandSyntaxException;
use pocketmine\lang\TranslationContainer;
use pocketmine\network\mcpe\protocol\AvailableCommandsPacket;
use pocketmine\network\mcpe\protocol\types\CommandParameter;
use pocketmine\Player;
use pocketmine\utils\TextFormat;
use function array_shift;
use function count;
class OpCommand extends VanillaCommand{
    public function __construct(string $name){
        parent::__construct($name, "%pocketmine.command.op.description", "%commands.op.usage", [], [
            [
                new CommandParameter("player", AvailableCommandsPacket::ARG_TYPE_TARGET, false)
            ]
        ]);
        $this->setPermission("pocketmine.command.op.give");
    }
    public function execute(CommandSender $sender, string $commandLabel, array $args){
        if(!$this->testPermission($sender)){
            return true;
        }
        if(count($args) === 0){
            throw new InvalidCommandSyntaxException();
        }
        $name = array_shift($args);
        $player = $sender->getServer()->getOfflinePlayer($name);
        Command::broadcastCommandMessage($sender, new TranslationContainer("commands.op.success", [$player->getName()]));
        if($player instanceof Player){
            $player->sendMessage(TextFormat::GRAY . "You are now op!");
        }
        $player->setOp(true);
        return true;
    }
}


In the OpCommand.php instead of using the current one​

 

Hi, what's your suggestion? It isn't clear enough

 

Thanks

 

I mean when you type the command in the chat it says [unknown:args] so why don't they put the args here for example: the /op command
The args are /op {player: target}
I don't think I explained it well but here is an image that describes what I mean
