Respond live on JSON-RPC

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"` to the AgentCard root. Without it, callers can't negotiate v0.x vs v1.0 compatibility.

info JWS signature 0/10

Card is unsigned (most published agents are).

pass Uptime track record 15/15

5/5 probes succeeded (100% uptime).

partial Skill declaration 6/10

Declares 1 skill — usable but thin.

            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`. We canonicalise these into the global skill taxonomy on next probe.

partial Verified Identity 5/10

Provider declared: Caldis (https://github.com/Caldis). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
