Worked on the MCDReforged/PluginCatalogue repository to streamline code by removing deprecated recipe unlock functionality. Focused on refactoring and code cleanup, the developer eliminated the unlock_recipe feature and associated outdated logic, reducing maintenance overhead and minimizing the risk of misconfiguration. This update involved careful analysis and removal of dead code, ensuring only active and supported code paths remain. The work, primarily using Python and Git, improved the maintainability of the codebase and set a foundation for easier future enhancements. By addressing a legacy bug and simplifying the unlocking logic, the developer contributed to a cleaner and more robust project structure.
