Toni Klopfenstein, Developer Relations Engineer at ADK Developer Relations. AI agents are moving from experimental scripts to full-fledged production services. For developers, this transition demands systems that are observable, secure, and extensible. Nineteen years after Google first created Golang, we are excited to carry forward that tradition of high-performance engineering with the release of Agent Development Kit for Go 143. These updates build upon the existing ADK Go architecture, which supports complex multi-agent systems—from step-by-step and concurrent SequentialAgents and ParallelAgents to iterative LoopAgents. Let’s explore the latest ADK Go features, including: Utilizing OpenTelemetry for comprehensive, in-depth tracing. Implementing self-healing capabilities using the Plugin System. Implementing safety guardrails for sensitive operations through Human-in-the-Loop approvals. Defining agents through YAML configurations to enable scalable portability.
