Worked on enhancing reproducibility and stability in the NVIDIA-NeMo/Gym repository by addressing environment drift related to the OpenClaw agent. Focused on backend development and configuration management, the work involved pinning the OpenClaw agent version explicitly within YAML configuration files, aligning with established git-ref pinning practices used for other agents. Updated the configuration schema, default settings, and test suite to enforce explicit versioning, thereby reducing nondeterminism in evaluation runs. Utilized Python and YAML to implement and test these changes, ensuring that execution environments remain consistent and reliable across different setups. The contribution centered on a single, well-defined bug fix.
