  file: a2a/the-hog-agent-card.json
grade_basis: 'Passes every A2A 1.0.0 hard check: capabilities is a JSON OBJECT, protocolVersion is present, and skills is an ARRAY. The optional fields A2A 1.0.0 asks for -- preferredTransport, defaultInputModes and defaultOutputModes -- are all present.'
deviations:
- field: protocolVersion
  value: '0.3'
  note: Declares A2A protocol 0.3, not 1.0.0. The card is structurally conformant to 1.0.0 but self-identifies against the older protocol revision.
- field: url
  value: https://docs.thehog.ai/
  note: The card's url and supportedInterfaces[0].url point at the documentation site root, not at an A2A JSON-RPC agent endpoint. An A2A client cannot send a message/send to https://docs.thehog.ai/ -- the card is discovery + skill advertisement, not a callable A2A transport.
- field: skills[0].tags
  value: []
  note: Skill declares an empty tags array; no routing tags published.
- field: supportedInterfaces
  note: Advertises protocolBinding HTTP+JSON at the docs root. No JSONRPC or GRPC binding is published.

  note: NOT A HIT. platform.thehog.ai is a Vite/React SPA whose catch-all answers 200 with the same index.html for EVERY /.well-known/* path probed (agent-card.json, agent.json, security.txt, api-catalog, ai-plugin.json, openid-configuration all returned 200 text/html "The Hog API developer console"). Recorded as a false positive, not as an agent card.

note: The card is Mintlify-generated docs-site metadata served from The Hog's own documentation host. It is a genuine provider-served AgentCard document and is recorded as one, but it advertises a documentation surface and an Agent Skill -- the callable agent surface The Hog actually ships is the MCP server at https://mcp.thehog.ai/mcp (see mcp/the-hog-mcp.yml).
