AWS adds skill-specific evaluation for agents using reusable procedures
Focus: Agents for Everyone
Date: September 22, 2026
Topics: Agent Skills, agent evaluation, Strands Evals, AgentCore
Evidence: Official Announcement
Availability: Published
Summary: AWS shows how Strands Evals and Amazon Bedrock AgentCore Evaluations can test whether skill-equipped agents select the correct reusable skill and follow its instructions, rather than judging only the fluency of the final answer.
Why it matters: Agent Skills turn repeatable methods into portable instructions, but they also create a new failure surface: the agent can choose the wrong skill or ignore the skill’s procedure. Skill-selection and instruction-following metrics make that behavior testable.
What to do now
Test one reusable skill for selection and instruction fidelity: Create representative tasks, measure whether the agent invokes the correct skill, and verify that required steps are followed before scaling.
