Transport — Agent wire protocols
ACP
Wire formats between agents, hosts, and tool servers. Two lineages share the acronym: Zed's Agent Client Protocol (editor↔agent, JSON-RPC — how JetBrains/VS Code embed terminal agents) and IBM's earlier Agent Communication Protocol, now folded into A2A. agentclientprotocol.com ↗
