Loop the inventory of player's tool

[pokw]

How do I loop the inventory of a player's tool? This is the code I have right now if someone can help.

command /command:
  trigger:
    player's tool is shulker:
      loop the inventory of player's tool:
        if loop-inventory contains dirt:
          send "loop inventory contains dirt"
        else:
          send "loop inventory does not contain dirt"
       send "loop started"
    send "command executed"

Errors:

Are you trying to know what the player is holding? or are you trying to see whats in their inventory?
Inventory:

Loop player's inventory

Held item:

if player's held item is #blah blah

I'm trying to see what's in the inventory of their held item, the shulker.

You cant rlly loop the inventory of the shulker if its in their hand. Or possibly not at all but you can edit use NBT Data
