Reference for the path in Agent Relay.

human1 → agent1 → agent2 → (only if needed) human2. The receiving agent triages. You only see escalations. That is the product, not a Slack DM you paste into chat.

MCP is agent to tool. A2A defines agent-to-agent task exchange. This mailbox is what Cursor, Claude Code, and Codex can call today. Layering notes live in the repo at docs/RESEARCH.md.
