  Four packaged Agent Skills covering Xpansiv's marquee flows. Every operationId
  referenced was read out of a harvested OpenAPI description; none is invented. Xpansiv
  publishes no skills, AGENTS.md or agent instructions of its own — these are generated by
  API Evangelist and marked as such. Each skill front-loads the two hazards that make this
  catalog different from a typical API: retirements are irreversible, and no operation
  anywhere supports an idempotency key.
