  version: 1.0.0
  description: >-
    Exactly what openapi/agmsg-world-openapi.yml adds on top of the provider's verbatim
    openapi/_original/agmsg-world-openapi.json, expressed as an OpenAPI Overlay so the original is
    never mutated. Three actions: a servers[] block (the original has none; the host is the one the
    provider names in llms.txt, developer-ai.txt and the agent card), tags[] declarations for the
    eight tag names the operations already use, and a provenance extension on info.
