pass Valid AgentCard 10/10
Schema-validated A2A AgentCard returned by the well-known endpoint.

Live probe hasn't run yet.
fail Protocol version 0/10
No protocolVersion in card.
How to earn +10 points

Card is unsigned (most published agents are).
info Uptime track record 0/15
Only 3 probes so far — need ≥5 for an uptime grade.
fail Skill declaration 0/10
No skills declared in card. Hard to route to.
How to earn +10 points
Declare your skills
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.
