How to properly make an "API" for my addon

[MexicanR]

So I'm currently creating an anti-spam addon and I have the chat commands in the main lua file. I was wondering how I could give said chat commands their own file or make an "API" out of them. Below are the commands and the two functions needed to check the params for them.

--[[Check Boolean Function]]--
local function CheckBooleanFunc( input )
	if(input == "on") then // if input = !ras on
	   return true //the boolean returns true
	elseif(input == "off") then //if input = !ras off
	   return false //the boolean returns false
	end
end

--[[Check Numbers Function]]--
local function CheckNumberFunc( input )
	if ( type(tonumber(input)) == "number" ) then //if the input is an actual number
		if ( tonumber(input) >= 0 ) then //then if the input is a number that is >= 0
			return tonumber(input) //the function returns the number
		elseif ( tonumber(input) < 0 ) then //otherwise the function will return 1
			return '1'
		end
	end
end

--[[Enable-Disable Chat Commands]]--
hook.Add( "PlayerSay", "RASChatCommands", function( ply, text, public )
    text = string.lower( text )
    text = string.Explode( " ", text )

	if ( #text > 1 and text[1] == "!ras" ) then
		if ply:IsSuperAdmin() then
			if ( text[2] == "on" ) then
				RAS.Settings.AntiSpamming = true //Change das value.
				RAS.ChatPrint( "Anti-Spam has been enabled by "..ply:Nick() )
				RAS.Log( "Enabled by "..ply:Nick() )
				return ''
			elseif ( text[2] == "off" ) then
				RAS.Settings.AntiSpamming = false
