2 things 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://srun66.com/.well-known/agent-card.json and the next probe clears this panel.

Field	What we saw	What we stored
`capabilities`	Input should be a valid dictionary or instance of Capabilities	dropped — this field was not indexed

pass Valid AgentCard 10/10

Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).

pass Live JSON-RPC 25/25

Endpoint responds to a negotiated A2A SendMessage probe (answers in ~50 ms).

fail Protocol version 0/10

No protocolVersion in card.

            How to earn +10 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

info JWS signature 0/10

Card is unsigned (most published agents are).

info Uptime track record 0/15

Only 1 probe so far, need ≥5 for an uptime grade.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

Provider declared: CryptoAgentMail (https://srun66.com). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

            How to earn +5 points
