notes: >-
  Anthropic authors the Agent Skills specification itself and publishes a public
  first-party skills library at github.com/anthropics/skills (19 skills at time
  of harvest). The three saved verbatim below are the ones that describe
  Anthropic's own developer surface. The remaining three are generated by API
  Evangelist from this repo's OpenAPI, grounded in real operationIds, mirroring
  the arazzo/ workflows.
