Shubhankar developed foundational data lineage traversal capabilities for the Atlan MCP Server within the atlanhq/agent-toolkit repository, enabling automated discovery of upstream and downstream asset relationships. Leveraging Python and the Atlan API, Shubhankar implemented a framework for cursor rules and integrated pre-commit checks to enforce code quality standards, reducing the risk of regressions. The work focused on establishing governance-ready lineage features rather than bug fixes, laying the groundwork for future reliability improvements. By combining lineage traversal logic with code quality tools, Shubhankar addressed both data governance needs and maintainability, delivering a robust feature that supports traceability and quality assurance.
