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 ~185 ms).

partial Protocol version 5/10

Declares pre-1.0 A2A 0.3.0 (Google preview). Upgrade to v1.x for full points.

            How to earn +5 points
          

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.

Docs →

info JWS signature 0/10

Card is unsigned (most published agents are).

pass Uptime track record 15/15

61/63 probes succeeded (97% uptime).

partial Skill declaration 6/10

Declares 2 skill, usable but thin.

            How to earn +4 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags` — `description` and `tags` are REQUIRED on AgentSkill since A2A v1.0, and tags are what discovery filters match on. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

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

            How to earn +5 points
          

Verify your domain ownership

Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.
