What is a “quality check”?

In the Appendix A of Ghosts of Saltmarsh, there is a section about Magical Storms on page 105, relating to each of the different schools of magic. The one about divination magic says:

What is a “quality check”? Is this a mistake? I assume it means ability check, but maybe it refers to something from a previous edition of D&D (I know that the adventures were from previous editions, so maybe these rules were lifted from previous editions too?). Has there been errata released about this?
