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 ~55 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"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

pass JWS signature 10/10
Agent card is JWS-signed and signature verifies.
pass Uptime track record 15/15
59/59 probes succeeded (100% uptime).
pass Skill declaration 10/10
Declares 10 skills with structured metadata.
partial Verified Identity 5/10
Provider declared: Codex Autonomous Worker (https://codex-autonomous-worker.rwdburley.chatgpt.site). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
How to earn +5 points
