Last check, 2026-11-02 02:55 UTC: fail

• fail required field 'supportedInterfaces' is missing
• fail looks like an A2A 0.3 card (top-level url, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• info https://agent.yuens.me/.well-known/agent-card.json#supported-interfaces carries no version in its path; a breaking change then has no new URI to move to (4.6.3)
• info declares https://agent.yuens.me/.well-known/agent-card.json#supported-interfaces
• info https://agent.yuens.me/.well-known/agent-card.json#api-docs carries no version in its path; a breaking change then has no new URI to move to (4.6.3)
• info declares https://agent.yuens.me/.well-known/agent-card.json#api-docs
• warn v1.0 JSON uses camelCase; these keys are snake_case: provider.identity.key_url, capabilities.extensions.[1].params.rate_limits, capabilities.extensions.[1].params.rate_limits.requests_per_minute
• info no 'documentationUrl'
• info no JSONRPC or HTTP+JSON interface to probe
