Evaluate AI agents systematically with Agent-EvalKit

AWS Labs released Agent-EvalKit, a free open-source toolkit under the Apache 2.0 license that tests AI agents by tracing their full execution path, not only their final answers. It plugs into AI coding assistants including Claude Code, Kiro CLI, and Kilo Code, running evaluation through six phases inside the developer's workspace. In a sample travel research agent, the toolkit caught the agent inventing exchange rates and temperatures when its web search came back empty, a failure that polished-looking output alone would hide.
