   AWS details a nine-stage AI agent evaluation framework on Bedrock AgentCore

   An AWS Machine Learning Blog post describes how AWS's Sales, Marketing, and Global Services (SMGS) Operations team built a continuous quality-evaluation framework for a production multi-agent system on Amazon Bedrock AgentCore Evaluations. The framework spans nine lifecycle stages—defining quality, experimentation, CI merge checks, CD production gates, canary scoring, adversarial testing, live drift detection, a real-time pulse, and an automated feedback loop—and runs at three levels at once: tools, individual sub-agents, and multi-agent orchestration, each with its own golden set and promotion criteria. AWS reports that its internal sales agents produced fluent but wrong answers such as labeling $410.08 of three-month revenue as "$410.08 Million" and presenting estimates as sourced facts while conventional monitoring stayed green; in one pre-production test, mismatched data, tool, and prompt changes dropped the pass rate from 78 percent to 38 percent.

   AWS proposes Trust in Depth framework for agent autonomy

   An AWS Machine Learning Blog post by Shawn Bice, vice president of AI Services, introduces a framework called Trust in Depth that would let AI agents act on their own when their actions can be verified, reserving human judgment for decisions that need it. The post frames trust as four lifecycle questions — scoping the agent before it runs, knowing its identity and authorization at deployment, bounding what it says and does while running, and reconstructing what happened afterward — and maps them to AWS Agent Registry, AgentCore agent identity and policy enforcement, Amazon Bedrock Guardrails and automated reasoning checks. It argues that content filtering, testing or monitoring alone cannot promise an agent will behave correctly next time, so limits should be enforced deterministically outside the agent's reasoning to hold even when it is buggy, manipulated or hit by prompt injection.

   AWS tutorial: build a slide-generating agent on Amazon Bedrock AgentCore

   An AWS Machine Learning Blog post walks through building a system that turns quarterly reports, compliance documents and market analyses into PowerPoint decks using Amazon Bedrock AgentCore. A single supervisor agent runs on AgentCore runtime and uses the Strands Agents framework to route requests between a document-generation tool and a summarization tool, with a RAG pipeline built on Amazon Bedrock Knowledge Bases, Amazon OpenSearch Serverless and Amazon Titan Text Embeddings v2. Anthropic Claude Sonnet 4.6 writes the content, Stability AI Stable Image Inpaint creates slide images, and a .NET 8 minimal API exposes the workflow to existing enterprise applications; AWS says the flow finished in under 90 seconds in its internal testing, and a public code repository is included.

   Tamnoon builds Tami, an agentic cloud remediation orchestrator on Amazon Bedrock

   An AWS Machine Learning Blog post describes how Tamnoon built Tami, an agentic cloud remediation orchestrator, on Amazon Bedrock. Tami ingests findings from CNAPP and cloud-native tools such as Wiz, CrowdStrike and AWS Security Hub, then uses four specialized agents — investigation, safety scoring, remediation and code generation — to produce fixes rated SAFE, RISKY or AWAITING DATA, with Bedrock Guardrails, a generate-and-review loop and human approval gating execution. Tamnoon says the approach cut critical cloud exposure by more than 90% in 90 days with zero production issues; those figures are the vendor's own and have not been independently verified.

   Qlik Answers scales grounded enterprise AI on Amazon Bedrock

   In an AWS blog post, Qlik detailed the architecture behind Qlik Answers, its enterprise question-answering product: employees ask in natural language and get sourced answers drawn from knowledge bases, live analytics apps, glossary definitions or documents, across more than 40,000 customers and 11 Regions. The system is split into entry, routing, answer, specialist-agent, conversational-analytics, retrieval (Amazon OpenSearch Service) and model-access layers; model calls go through Qlik's own LLM gateway to Amazon Bedrock, with Bedrock Guardrails applying content filtering and contextual grounding validation to every request and response, and Amazon SageMaker AI hosting models not yet available in-Region. Qlik says that since February 2026 general availability its Discovery Agent has surfaced over 100,000 discoveries, that most Qlik Cloud accounts with agentic tools enabled keep using them, and that customer Lintech International saw 75% faster responses and up to 7 hours per week returned to managers — all figures reported by Qlik itself.

   AWS shows layered evaluation for multi-agent systems with AgentCore Evaluations

   An AWS blog post explains how to assess multi-agent systems with Amazon Bedrock AgentCore Evaluations, combining built-in evaluators (helpfulness, task success, instruction following, tool selection) with custom evaluators for domain rules such as constraint satisfaction, route feasibility and SQL correctness. The walkthrough uses a fictional retailer, AnyCompany Retail, building a supply-chain decisioning system with the Strands Agents SDK: one orchestrator agent plus optimization, distribution, routing and analytics sub-agents running on AgentCore runtime with memory and observability. A separate explainability layer of six cross-cutting evaluators checks decision rationale, evidence attribution, constraint reasoning, trade-off explanation, tool-use explainability and assumption disclosure; AgentCore Evaluations runs in on-demand mode for benchmarks and CI/CD gates, and online mode to sample production traces into CloudWatch dashboards and alarms.
