AWS Launches Agent-EvalKit for LLM-Powered Agent Evaluation
Agent-EvalKit introduces an open-source evaluation pipeline that integrates LLM-as-judge evaluators and AI coding assistants directly into agent development workflows, creating new attack surfaces where poisoned test cases, manipulated ground-truth datasets, and adversarial evaluation prompts could corrupt agent quality signals. The toolkit's deep code-reading access via Claude Code, Kiro CLI, and Kilo Code means a compromised evaluation run could exfiltrate source code or inject malicious recommendations into the development pipeline. Because evaluation outputs drive concrete code changes, adversarial manipulation of the eval layer has downstream consequences for production agent behaviour.
