Build reliable multi-agent applications with ADK Go 2.0. Discover our new graph-based workflow engine, built-in human-in-the-loop, and dynamic orchestration- Google Developers Blog

ADK for Go 2.0 introduces a graph-based workflow engine for composing multi-agent applications, built-in human-in-the-loop (HITL) as a primitive, dynamic orchestration in Go, LLM agent modes, and a unified node runtime. It enhances resilience with built-in retry policies, timeouts, and concurrency controls. The update also unifies agent and workflow execution models and introduces a single `agent.Context` for tools, callbacks, and workflow nodes.
