Developed foundational data lineage capabilities for the Atlan MCP Server within the atlanhq/agent-toolkit repository, focusing on enabling traversal of upstream and downstream asset relationships. Leveraged Python and the Atlan API to implement lineage traversal logic, allowing for comprehensive discovery of asset dependencies. Introduced a framework for cursor rules and integrated pre-commit checks using code quality tools, establishing automated quality gates to prevent regressions and support governance requirements. The work emphasized reliability and maintainability, laying the groundwork for future enhancements. No major bug fixes were addressed during this period, as efforts centered on robust feature delivery and code quality improvements.
