Arnav focused on enhancing code quality and maintainability for the IBM/mcp-context-forge repository by developing automated Python tooling to verify and enforce file header standards. He implemented a script in Python that checks and corrects headers for shebang, encoding, copyright, license, and author metadata, reducing licensing risk and ensuring consistency. To integrate this process into the development workflow, Arnav added Makefile targets and a GitHub Actions workflow, enabling continuous enforcement of header compliance both locally and in CI/CD pipelines. His work leveraged automation, scripting, and YAML configuration, resulting in improved coding standards and clearer licensing across the codebase.
