pass Valid AgentCard 10/10

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

fail Live JSON-RPC 0/25

Card declares a URL but that URL returns 404.

            How to earn +25 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.

pass Protocol version 10/10

Declares A2A 1.0 with supportedInterfaces[] (current v1 card shape).

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.

partial Skill declaration 8/10

Declares 7 skills with structured metadata. 7 of 7 skills lack tags or a description — both REQUIRED on AgentSkill since A2A v1.0; discovery filters cannot match an untagged skill.

            How to earn +2 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.

fail Verified Identity 0/10

No provider organisation declared. Anonymous agent.
