Strands Evals and Amazon Bedrock AgentCore for skill-equipped agent evaluation
Evaluate skill-equipped agents with Strands Evals and Amazon Bedrock AgentCore
Fluency metrics hide whether an agent actually picked the right skill and followed its steps, and this guide shows how to turn that hidden failure mode into measurable scores. Builders deploying skill-based agent frameworks can use Strands Evals with AgentCore Evaluations to catch wrong-skill selections before production. It contrasts with generic answer-quality benchmarks by targeting procedural compliance directly.
AWS published a guide on 2026 showing how to evaluate agents that use skills — reusable, portable instructions encoding domain-specific procedures.
The tutorial covers measuring skill selection and instruction following using Strands Evals together with Amazon Bedrock AgentCore Evaluations.
It addresses the gap where a fluent answer does not prove the agent chose the correct skill or executed it properly.
The walkthrough is hosted on the AWS Machine Learning Blog.
