Nova tool routes

I'm trying to figure out how Nova determines if a dashboard/tool exists or not

https://example.com/nova/{toolname}
https://example.com/nova/base-tool - if we create a BaseTool tool, this works
https://example.com/nova/price-tracker - this doesn't work if PriceTracker inherits BaseTool

My question is basically how does base-tool get registered and routed to BaseTool class? The context is, I'm trying to create an inheritable tool and for each inheritance child, I like to have a different nova toolname, possible?

Thank you.
