description: 'A2A Agent Card observed at the pre-0.3 legacy path /.well-known/agent.json on ainglish.org (the canonical
  /.well-known/agent-card.json returned a real 404 on both ainglish.org and www.ainglish.org; the same body is served
  on www). Graded against the A2A 1.0.0 AgentCard object: capabilities is an object and skills is an array, but
  there is no protocolVersion, so the card is ''flavored'' - an agent card in spirit rather than in schema. The
  card''s url is the REST base https://ainglish.org/api/v1 and its endpoints[] array names REST, OpenAPI and MCP
  (streamable-http at https://ainglish.org/mcp) interfaces rather than an A2A JSON-RPC endpoint, so the agent is
  reachable over HTTP/OpenAPI and MCP, not over the A2A protocol. Provider-published by construction; nothing here
  is derived or generated. The provider''s own llms.txt, /api/v1 index, /developers page and ai-plugin manifest
  all link this card.'
