When A2A Tasks Sat Stuck in 'working' — Field Notes on Tracing State Transitions to Detect Stalls
Antigravity's A2A coordination fails less by crashing and more by sitting in 'working' without progress. This walks through recording state transitions as one timeline and naming a stalled task down to which agent and which edge froze, along with what running agents daily has taught me.
Google Antigravity May 2026 Update Roundup — UE5 Integration, A2A Support, AgentKit 2.0 Refinements
What's worth knowing in Google Antigravity as of May 2026: Unreal Engine 5 integration, the A2A protocol, and AgentKit 2.0 refinements — covered with the on-device behavior I observed, not the marketing copy.
Implementing Antigravity's A2A Protocol — Practical Patterns for Agent-to-Agent Conversation
A hands-on guide to Antigravity's A2A (Agent-to-Agent) protocol. Walks through the minimal two-agent setup and three real-world patterns — fire-and-forget, bidirectional confirmation, and scatter-gather — with runnable samples.
