Worked on enhancing system tooling and observability across two repositories, focusing on robust solutions for legacy and secure environments. In METR/vivaria, delivered cgroup v1 memory statistics support in pyhooks by implementing logic to detect cgroup v1 file paths within Python system utilities, ensuring accurate RAM reporting in older Linux deployments and updating automated tests for compatibility. In UKGovernmentBEIS/inspect_ai, improved sandbox tooling by refining non-root installation workflows, adding permission checks and error handling to stabilize CLI tool usage for non-root users. Leveraged DevOps practices, Linux internals, and Python system programming to address reliability and usability challenges in complex environments.
