deviations:
- field: protocolVersion
  observed: '0.3'
  note: >-
    Declares A2A protocol 0.3, not 1.0.0. The card is a pre-1.0 flavor that still
    satisfies every 1.0.0 hard check.
- field: description
  observed: absent
  note: >-
    A2A 1.0.0 requires a top-level human-readable `description` on the AgentCard;
    this card omits it.
- field: supportedInterfaces
  observed: present
  note: >-
    Uses the 0.3-era `supportedInterfaces` array rather than 1.0.0
    `additionalInterfaces` / `url` + `preferredTransport` pairing.
- field: skills[].tags
  observed: '[]'
  note: The single declared skill carries an empty tags array, so it is not discoverable by tag.
notes: >-
  The card is served by the Starbridge Help Center (hc.starbridge.ai), a
  Mintlify-hosted docs property on a Starbridge-controlled subdomain, and it
  describes documentation-answering rather than the Starbridge product API.
  The declared skill resolves to a real provider-published Agent Skill
  (skills/starbridge-published-skill.md, HTTP 200). The product agent surface is
  the separate hosted OAuth MCP server at https://dashboard.starbridge.ai/mcp/oauth
  (see mcp/starbridge-mcp.yml); neither dashboard.starbridge.ai nor starbridge.ai
  serves an agent card.
