Simon Willison explored smolmachines/smolvm as a sandbox for untrusted Python and JavaScript code, aiming to execute user-provided tasks securely. He tasked Claude Fable-5 with the research, which encountered limitations in its own execution environment (Claude Code for web) due to the lack of nested virtualization. The AI then creatively devised a solution using GitHub Actions runners to perform the necessary tests, demonstrating a proactive approach to overcoming environmental constraints. AI
IMPACT Demonstrates AI's capability in testing and problem-solving within constrained environments, potentially accelerating development cycles for sandboxing technologies.
RANK_REASON The item discusses the use of an AI model (Claude Fable-5) to test a specific software tool (smolvm) for a particular use case (sandbox environment), rather than a new release from a frontier lab.
