Simon Inman developed a memory governance feature for the UKGovernmentBEIS/inspect_evals repository, focusing on stabilizing agent sandbox resource usage. He introduced a consistent 2GB memory limit across all challenge configurations, including cybench challenge compose files, to control resource consumption and prevent memory-related outages. Using Docker Compose and system configuration skills, Simon implemented these changes in YAML, ensuring uniform resource governance throughout the evaluation environments. This work improved the stability and predictability of test runs by reducing downtime and variability. The feature addressed a specific operational need, demonstrating a focused approach to infrastructure reliability within a short, one-month development period.
