Schema-validated A2A AgentCard returned by the well-known endpoint.
fail Live JSON-RPC 5/25
Endpoint replies but body isn't a valid JSON-RPC 2.0 A2A response.
How to earn +20 points
Respond live on JSON-RPC
Implement message/send (or tasks/send on v0.x). Return a 200 with a valid JSON-RPC response. Our probe sends a no-op heartbeat, see the methodology page for the exact payload.

partial Protocol version 2/10
Declares unrecognised version '2025-11-25'.
How to earn +8 points

Docs →

Card is unsigned (most published agents are).
pass Uptime track record 15/15
19/19 probes succeeded (100% uptime).
fail Skill declaration 0/10
No skills declared in card. Hard to route to.
How to earn +10 points

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 →
fail Verified Identity 0/10
No provider organisation declared. Anonymous agent.
How to earn +10 points
