Alex worked on the MCDReforged/PluginCatalogue repository, focusing on improving the accuracy of first-time contributor detection. To address unreliable analytics caused by brittle string parsing, Alex refactored the check_contributor logic to use the GitHub CLI GraphQL API, switching from space-delimited string parsing to robust JSON response handling. This change stabilized contributor attribution, ensuring that onboarding signals and contributor metrics reflected actual repository activity. The work involved Python scripting, API integration, and the use of GitHub Actions to automate the process. Alex’s targeted bug fix enhanced the reliability of contributor analytics, supporting better data-driven decisions for the project maintainers.
