deviations:
- id: protocol-version-0-3
  severity: informational
  detail: protocolVersion is "0.3", not "1.0.0" — the card is published against the pre-1.0 A2A draft. All hard conformance checks still pass.
- id: docs-scoped-agent
  severity: informational
  detail: The card describes the documentation agent ("Gameball Docs"), not the Gameball REST API itself. url and supportedInterfaces both point at https://docs.gameball.co/ rather than https://api.gameball.co. The single declared skill links to a provider-authored Agent Skill markdown file (saved verbatim to skills/gameball-skill.md) that documents the REST API.
- id: empty-skill-tags
  severity: informational
  detail: The one declared skill carries an empty tags[] array.
