Evaluate AI agents systematically with Agent-EvalKit

TL;DR

Agent-EvalKit is an open-source toolkit (Apache 2.0) that makes this evaluation infrastructure available by integrating with AI coding assistants, including Claude Code, Kiro CLI, and Kilo Code. This post walks through how Agent-EvalKit works across its six evaluation phases, using a travel research agent built with the Strands Agents SDK and Amazon Bedrock as a running example.

Nauti's Take

Finally, less vibes-based agent evaluation. Agent-EvalKit forces builders to test planning, tool use, and output quality separately.

That is where many flashy agents collapse: not on the first prompt, but on the third step with real constraints.
