You're right; there should be an evaluable exit. But the place to put it is not in the execute() method; instead, it should be in the bin/pds-skeleton script. If you can, modify this PR (or submit a new PR) so that bin/pds-skeleton takes the return from the execute() method, and then uses that for an exit code. Make sense?
