How Anthropic limits AI agent blast radius #1 𝕏 Alexandr Wang shows that Muse Spark 1.1 outperforms Opus, Grok 4.5, and Gemini on a new challenging finite model theory/theoretical CS benchmark, underlining its advanced reasoning capabilities. #2 📝 Anthropic Engineering How we contain Claude across products - Anthropic engineers describe techniques for limiting the potential blast radius of increasingly capable agents by building containment across claude.ai, Claude Code, and Cowork. The article shares learnings and engineering approaches used to keep product integrations safe and reliable. #3 ▶️ The Correct Way to Build and Manage AI Agents in 47 Minutes | Jared Zoneraich Peter Yang Devon orchestrates a master AI agent to launch ten cloud-based child agents in parallel, each running in its own VM to redesign a landing page and perform automated integration tests via Devon’s Test App feature. Master Devon session spawned 10 child Devons in parallel, each running in its own VM to clone the codebase, apply redesign changes on a new Git branch, and open a pull request. Devon’s Test App feature ran integration tests in a live browser VM by programmatically clicking specified UI elements on the updated landing page to verify link functionality. A single Devon agent maintained a continuous 9-hour run on Cognition’s cloud platform without human supervision, showcasing extended asynchronous execution. #4 𝕏 Claude extends Claude Fable 5 access to all paid plans and keeps Claude Code’s weekly rate limits 50% above normal through July 19.
