description: 'Packaged Agent Skills for the API League platform. Every operationId referenced in every
  skill was grepped out of the provider''s own OpenAPI — none is invented — and every required/optional
  parameter split is read from the spec. The skills exist because API League''s runtime semantics are
  NOT discoverable from the contract alone: the token cost model, the X-API-Quota-* headers, the absence
  of Retry-After, the separate concurrency ceiling, the one-hour caching restriction in the terms of use,
  and the fact that storeKeyValueGETAPI writes through an HTTP GET are all facts an agent has to be told.

  api-league-getting-started.md is the prerequisite for the other six.'
