A2A Agent Card — Builds a spec-correct A2A Agent Card JSON by fetching the live protocol schema first.

Qué hace

Generates the A2A discovery document (agent-card.json) describing an agent's identity, capabilities, skills, and authentication. Instructs Claude to fetch the current A2A protocol spec live before writing fields, so it tracks schema evolution (e.g. the securitySchemes/security split) instead of relying on stale training knowledge. Triggers when a user is defining what their agent exposes to other agents over A2A.

Informe de la prueba

Fetched the live A2A spec and confirmed the skill's securitySchemes/security + protocolVersion fields are the current schema; a memory-only baseline card used the deprecated 'authentication' field and dropped protocolVersion entirely.
