The tool is designed so that the tip at the end of the tool fits into the cylinder center pin hole in the frame if the crane is aligned.
Without the tool, I suppose one could simply try to look closely at the closed cylinder to see if the inner ejector rod pin is meeting the frame hole perfectly. Or maybe look for uneven wear on the pin or frame hole.

Let me ask this: If you get the chance to shoot a revolver and it is performing perfectly (e.g. not spitting lead, not binding, etc.) is it still something to worry about?

Generally I would say no.
If however, you were to measure it with a gauge and it was showing it was terribly out of spec I would replace/repair it on principle.

On a Smith you take the cylinder off the yoke and drop the alignment tool inside the yoke.
The pin should fall into the bolt hole when the yoke is closed.
My best guess to check for a bent yoke/crane for a Ruger is a rod that is the size of the bore. Drop it down the barrel and if it drops into the cylinder charge holes without binding you have no problem.
I have never had to mess with a bent Ruger.
