Agent evals are becoming production infrastructure, AWS case study says
krishnan · x · 2026-07-26
A post argues that agent evaluation is becoming production infrastructure, not just a demo afterthought.
It cites an AWS blueprint using Strands and Amazon Bedrock AgentCore, plus a Motorway case study claiming the eval pipeline cut incorrect results from 1 in 8 queries to 1 in 50 and reduced issue detection time from hours to minutes.
The author frames the real shift as making agent behavior measurable before release:
- task completion
- correct tool use and parameters
- coherent reasoning across turns
- business-correct final answers
- staying within cost, latency, data, and safety constraints
The punchline: agents without evals are “vibes with API access.”
