1 thing in this card we could not use

Everything else was indexed. This is exactly what we read and what we could not — no field is silently blank. Fix the card at https://midaswhale.wtf/.well-known/agent-card.json and the next probe clears this panel.

partial Valid AgentCard 6/10

AgentCard did not read cleanly: 1 field we could not read. Scored on what we could read, not on a card that arrived as published — the card findings name every affected field and what we did with it. Declares A2A 1.0.0 but is missing v1.0 REQUIRED fields: capabilities, defaultInputModes, defaultOutputModes.

Publish a parseable A2A AgentCard

Serve a valid AgentCard JSON at /.well-known/agent-card.json. The A2A 1.0 schema is the reference; we accept the v0.x backwards-compatible variant too.

fail Live JSON-RPC 5/25

Endpoint replies but body isn't a valid JSON-RPC 2.0 A2A response.

            How to earn +20 points
          

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

Docs

partial Protocol version 9/10

Declares A2A 1.0.0 with supportedInterfaces[] (current v1 card shape). protocolVersion '1.0.0' carries a patch component; A2A §3.6 wants Major.Minor ("1.0") — patch numbers must not appear in cards or the A2A-Version header.

            How to earn +1 point
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` (Major.Minor, no patch number — §3.6) to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.
