  Ghost publishes an A2A Agent Card from its own developer documentation host. The card
  advertises a single skill ("Ghost") backed by a published Agent Skill markdown file,
  and is served alongside the remote MCP server at https://docs.ghost.org/mcp. The card
  covers the documentation agent surface, not the Content/Admin REST APIs themselves.

deviations:
- field: protocolVersion
  observed: '0.3'
  expected: '1.0.0'
  severity: minor
  note: >-
    Card declares the pre-1.0 A2A protocol version. It is still discovered at the
    canonical /.well-known/agent-card.json path.
- field: description
  observed: absent
  expected: a top-level human-readable description string
  severity: minor
  note: A2A 1.0.0 lists description among the required AgentCard fields; this card omits it.
- field: supportedInterfaces
  observed: present
  expected: additionalInterfaces
  severity: minor
  note: >-
    The card uses `supportedInterfaces[]`; A2A 1.0.0 names the equivalent member
    `additionalInterfaces[]`. Same shape (url + protocolBinding), different key.
- field: skills[].url
  observed: present
  expected: not defined by the A2A AgentSkill schema
  severity: informational
  note: >-
    Non-standard extension that points at the published Agent Skill markdown. Useful in
    practice — it is how the skill file was located and saved.
