DON'T BUILD MULTI-AGENTS

Multi-agent frameworks for LLM agents aren't great, as they have disappointing performance and fragility. Instead, a "Context Engineering" approach is better, where it's needed to share full agent traces to maintain context and avoid conflicting decisions. For the best agentic experience, start with a single-threaded linear agent for simplicity and later incorporate a new LLM to compress history for longer contexts.

S1NGULARITY: SUPPLY CHAIN ATTACK LEAKS SECRETS ON GITHUB

Multiple malicious versions of the popular Nx build system package were published to NPM on August 26. The attack leveraged AI command line tools to search for sensitive files, extracted credentials, and then attempted lockout by appending `sudo shutdown -h 0` to .bashrc and .zshrc files. The root cause of the supply chain attack was a flawed GitHub Action that allowed code injection through unsanitized PR titles combined with the `pull_request_target` trigger.

TEACHING AI HOW SCIENCE ACTUALLY WORKS

Current AI for science consists of specialized tools built on curated data sets, but much of science is hands-on experimentation and unrecorded tacit knowledge. AI scientists will need multimodal datasets that capture that tacit knowledge for them to become truly capable. The IFP has proposed an effort to generate and use the multimodal data necessary to unlock the full potential of AI for science. The program involves creating a lab that would simultaneously conduct research while recording everything and then using that data to make the whole process more productive.

THE LARGEST PROJECT IN THE HISTORY OF HUMANITY IS ABOUT TO ENTER A KEY PHASE: THE FINAL ASSEMBLY OF THE REACTOR CORE, LED BY AN AMERICAN GIANT

Westinghouse Electric Company has secured a €168 million contract to lead the assembly of the core of ITER's fusion reactor. The critical operation will involve the precise installation and welding of nine massive steel sectors to form the tokamak's vacuum vessel, the heart of the fusion reactor. Each 400-ton sector must be positioned and welded with millimeter precision to create a perfectly circular, hermetically sealed chamber. ITER's primary technical goal is to demonstrate fusion power at a commercial scale. If successful, the project is expected to spawn multiple approaches to commercial fusion.

LESSONS ON BUILDING AN AI DATA ANALYST

This article looks at what it takes to build an AI data analyst. It provides tips on how to preserve quality where it matters without blowing up response times. Text to SQL isn't enough because the task is hard for current models - systems should instead run a multi-step workflow. Context and metadata can mean the difference between the right and wrong answer.
