We should also handle cases where there are multiple directives attached to this node rather than just checking the first directive.

I've added this. What is your take on this check:
if (node.directives && !this.directiveExcludeField([...node.directives])) {
//code
}node.directives is always truthy but TS requires the check in order to access the array value at node.directives.

The weight of Human and hero are both 1. Can you add something that differentiates the weights so we know that this is working.

Same here. Differentiate the weights of here and human

Differentiate weights here as well

I ended up refactoring things a bit to check all directives in the array.
