There are no resources metering functions as the number and variety of resources the DSPs can dynamically allocate are many and different. To do this monitoring it would be very complex and likely would eat up other resources.
In general you should try loading the algorithm to see if no errors or notices show up.
Another useful suggestion is that a Vsigfile (stored algorithm) around 24kb in its stored file is about to be at max size.
But loading remains the best test.
