I'm afraid it's not worth to build such a automatic tool.

Different resource clients uses different resource classes which have 
different resource items, so such a tool must understand which resource 
client is using which resource class, which is not easy or even 
possible. Or we can hard code this relationship in the tool, but this 
will make the tool prone to error in case any code changes.

So I suggest to check it manually every time we change any code in this 
area, of course manual check can be partially automated by some script 
but I don't think it's worth to develop a dedicated tool to do it as you 
still need manual check any way.

Thank you
