Agent A2a Protocol

Use this skill for complete A2A 1.0 behavior beyond single-hop agent-delegation. Required for Antigravity deployments and Coordinator scatter-gather patterns.

When to Use

• integrating multi-agent systems with structured A2A 1.0 communication
• exposing an agent service via Agent Cards and JSON-RPC invoke/stream
• operating as Antigravity and needing SSE progress + task handoffs
• coordinating scatter-gather across multiple agents
