How binding tools to admin commands ?

We can not make the script for you, however the script will use a combination of the Chatted Event, and String Manipulation.

Here's a sample code:

game.Players.PlayerAdded:connect(function(plr) --Player joined the game, now the function will handle what you want to do with the player.
    plr.Chatted:connect(function(chat) --Player said something the function will handle what to do with that too.
        if chat:sub(1,6) == ":give " then --Did the player say :give something?
            --Finish code
        end
    end)
end)
