    Building trust in AI agents: A production-ready evaluation framework with Amazon Bedrock AgentCore

    AWS explains how its SMGS Operations team built a nine-stage evaluation framework with Amazon Bedrock AgentCore for an internal sales intelligence system. The framework combines domain-specific evaluators, versioned golden datasets, CI/CD gates, continuous monitoring, and trace-driven improvements across tools, agents, and multi-agent workflows. AWS reports that automated evaluation reduced quality regression detection from days or weeks to under four hours.

    Why it matters: The framework offers a transferable way to connect domain-specific failure categories with release gates and production monitoring across tools, individual agents, and multi-agent workflows.

    ChatGPT’s updated Chrome extension reads open tabs and takes browser actions

    ChatGPT’s updated Chrome extension can read open tabs and act on them, and it works with all ChatGPT plans. Users can target tabs with @chrome, gather information across tabs in Chat mode, and use Work mode’s Computer Use to send messages, fill out forms, download files, or group tabs. The upgraded sidebar includes full chat history; OpenAI’s examples show product comparisons, article summaries, and comparisons of sellers’ pricing pages.

    Why it matters: Access to multiple open tabs and browser actions brings information gathering and task execution into the same ChatGPT workflow, with availability across all ChatGPT plans.

    Shopify opens its catalog up to more AI agents

    Shopify announced Tuesday that shoppers will soon be able to configure any AI agent to browse and purchase from over a billion catalog listings without a partnership integration. Customers connect an agent to their Shop account and check out using Shop Pay within the conversation, with orders routed back to the Shop app. Shoppers can set rules such as budget limits or fast shipping preferences, but must approve each purchase.

    Why it matters: The expansion moves agent shopping beyond individual partnership integrations, while requiring approval for each purchase gives customers a defined point of control over transactions.

    Building Agents That Transact With Anchor Browser and AgentCore Payments

    The guide explains how Anchor Browser integrates with Amazon Bedrock AgentCore payments to handle x402-protected pages and APIs within the same browser session. Setting session.x402 to true enables automatic payments subject to configured spending and expiration limits, while wallet credentials remain outside the agent runtime. Existing browser automation code can continue unchanged; rejected payments or unsupported challenges leave the original HTTP 402 response intact.

    Why it matters: The integration illustrates a transferable architecture for paid agent workflows by placing payment signing and budget enforcement outside the agent runtime while preserving browser session context.

    Google brings agent capabilities to Gemini, starting with enterprise customers

    At a Google Cloud event, Google announced a unified agent for Gemini that can accept goals rather than just instructions, plan tasks on its own, call custom skills and tools, and connect to internal enterprise systems.

    Why it matters: Google is turning Gemini into a unified agent that can be assigned goals and call tools autonomously, launching first for enterprise customers. Readers can use this to assess how enterprise agents are taking shape.

    How to build a context-aware AI assistant on AgentCore and OpenClaw

    An AWS blog post explains how to run the open-source agent system OpenClaw on the Amazon Bedrock AgentCore runtime to build Sprout, a personal assistant with long-term memory.

    Why it matters: The source provides reusable methods for container wrapping, namespaces, and prompt-cache ordering, helping readers build an agent with long-term memory.

    Microsoft's ThinkingBox agent benchmark checks final database state, not tool calls

    The Microsoft Copilot Studio team and Hugging Face jointly released ThinkingBox. It runs agents in isolated MCP tool sessions and then performs executable checks on final backend state and side effects, rather than judging only the final reply or whether tool calls were allowed.

    Why it matters: The agent benchmark from Microsoft and Hugging Face uses 507 stateful workflows and 20 repeated runs, shifting the focus from tool calls to the final database state.

    Anthropic launches Mods, a plugin system for Claude Code

    Anthropic released Mods for Claude Code, a middleware layer that runs inside the tool. Developers can use JavaScript or TypeScript functions to hook into events such as tool calls, user prompts, and UI rendering, adding custom panels, intercepting tool calls, or connecting new commands.

    Why it matters: Anthropic added plugin-style Mods middleware to Claude Code, showing how it changes extensibility and permission risks in coding tools.
