🎯 Skill Positioning

This skill covers @ant-design/x-card — the React implementation of the A2UI protocol, enabling AI agents to dynamically render rich interactive UIs through structured JSON command streams.

It covers:

• XCard.Box + XCard.Card component usage
• A2UI v0.9 command types: createSurface, updateComponents, updateDataModel, deleteSurface
• Custom component registration and catalog management
• Data binding via JSON Pointer paths (RFC 6901)
• Action handling — sending user events back to the agent
• Streaming progressive rendering patterns
• v0.8 ↔ v0.9 protocol differences

Scope: v0.9 is the recommended protocol. v0.8 is supported for backward compatibility only — prefer v0.9 for all new work.
