  Three packaged skills covering the marquee flows of the one FIS API with a publicly readable
  contract. Every operationId in every skill was grepped out of the harvested spec; none is
  invented. No skills are written for FIS Code Connect core banking, payments or wealth — their
  contracts sit behind a reviewed registration and there is nothing to ground a skill in.
