   Epsilon scales intent-driven UI testing with Amazon Nova Act

   Epsilon, a Publicis Groupe company, is using Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool to provide intent-driven UI testing as a shared service across its product teams. Its 50-engineer Agentic Platform team pairs natural-language test authoring with managed browser infrastructure while retaining Playwright as the regression-testing backbone. The AWS Machine Learning Blog also reports that saved test trajectories achieved a 100% pass rate in Epsilon's internal repeated-run benchmarks.

   Fingerprinting Script Uses Anti-LLM Obfuscation and Node-Gated Code

   A reverse-engineering report by veritas describes a fingerprinting script served from servicepipe.tech that embeds an obfuscated prompt designed to trigger AI safety safeguards, alongside references to biological weapons and other harmful instructions. Beyond that unusual text, the script collects standard browser and WebGL signals and appears to contain Node.js-gated code that reads local configuration files and attempts to download an executable. The report does not show that the embedded prompt actually creates biological weapons or that the Node.js branch executed in production.

   Tutorial Builds an AI Website-Cloning Pipeline with Playwright

   A Juejin tutorial explains how ai-website-cloner-template uses Playwright, Claude Code, spec files, and parallel builder agents to reproduce a website across desktop, tablet, and mobile viewports. The workflow captures screenshots and computed styles, generates React components, and compares the clone with the target during visual QA. Its author reports more than 70% fidelity in a Juejin test while noting that the result was not perfect and depended partly on model performance.

   Mastra explains Firecrawl browser provider, flags password exposure in traces

   Mastra published a walkthrough of @mastra/browser-firecrawl, a browser provider built by Firecrawl's team that it says gives an agent a hosted browser for pages behind a login without running Chromium locally, with a demo that logs into Sauce Labs' test store and checks out a backpack. Mastra says FirecrawlBrowser extends its AgentBrowser and exposes the same 16 browser tools by default, with the difference being that AgentBrowser launches Chromium locally with Playwright while FirecrawlBrowser connects to a Firecrawl session over CDP; sessions are tied to an agent thread, but the thread-to-session map lives in the server process, so restarts or another instance get a fresh browser with no cookies, and Firecrawl ends sessions after five minutes idle or ten minutes total by default. Mastra also warns that a password typed through the browser_type tool is recorded in memory and traces as plain text because the browser tool's field is called text rather than password; named profiles with saveChanges set to false let an agent start signed in without the model seeing the password.

   GitHub Copilot for Beginners: Teaching the App Your Codebase Conventions

   A GitHub Blog beginner tutorial explains how to give the GitHub Copilot app context about a project's own conventions and workflows. It describes four customization paths: custom instructions in .github/copilot-instructions.md plus path-specific files under .github/instructions that use an applyTo field; Agent Skills stored as folders such as .github/skills/quality-checks containing a SKILL.md and optional scripts; custom agents under .github/agents that define purpose, instructions, tools and project context for larger multi-file tasks; and MCP servers that connect Copilot to outside tools and data, for instance a Playwright server that lets it open and interact with an app in a browser. The post suggests starting with one convention you keep re-explaining and points to the community Awesome Copilot collection for ready-made instructions, skills and agents to adapt.
