pass Valid AgentCard 10/10

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

partial Live JSON-RPC 10/25

Card declares only gRPC / HTTP+JSON interfaces; the live probe covers JSON-RPC, so the endpoint was not exercised. Not a defect in the card.

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 5/10

Declares pre-1.0 A2A 0.3 (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

53/53 probes succeeded (100% uptime).

partial Skill declaration 6/10

Declares 1 skill, usable but thin. 1 skill without tags — optional in 0.x, REQUIRED once you move the card to v1.0.

            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: Base Documentation (https://docs.base.org/). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
