💬 Cursor used in Russian-speaking hacking campaign against Belgian chemical company and six other firms — Brad Heath reports Russian-speaking hackers used Cursor to help breach a Belgian chemical company and at least six other firms earlier this year. Coding assistants as attack tools is now a documented pattern.

💬 Terminal-Bench-Science: Evaluating AI agents on scientific research workflows — New benchmark for agents doing real scientific research workflows; HN is stress-testing whether the tasks in harbor-framework/terminal-bench-science are actually hard.

💬 Show HN: We built open OpenRouter that turns usage into a better model — Open-source Rust model gateway that routes across self-hosted, frontier, and open models — and uses usage data to improve the model. 203 points on HN.

The community is converging on two questions: can agents do real scientific work, and what happens when coding assistants become attack tools. Both answers are getting sharper.

📚 Copilot code review: Resolution reasons and expanded capabilities — Copilot code review adds comment resolution reasons and expanded capabilities — reviewers can now record why a thread was resolved, making review outcomes auditable.

📚 CIFQA: A Deterministic Tool-Grounded Multi-Agent LLM Framework for Financial Query Answering — CIFQA: deterministic tool-grounded multi-agent framework for financial QA — claims deterministic outputs by grounding each agent in tools; relevant if nondeterminism is a liability in your multi-agent stack.

Deterministic tool-grounding is the throughline: CIFQA applies it to financial QA, and Copilot's resolution reasons make review outcomes auditable — both push toward less guesswork in agent outputs.
