Worked on the wabbajack-tools/mod-lists repository to enhance mod source management by implementing a feature that updates and consolidates repository configurations. Focused on modifying the repositories.json file using JSON and configuration management skills, the work involved adding new repository entries and updating existing mod sources to streamline configuration changes. This approach reduced manual edits and minimized configuration drift, making future updates more maintainable. All changes were committed in a unified change-set, ensuring traceability for audits and rollbacks. The improvements laid a foundation for scalable mod list management, emphasizing maintainability and auditability within the repository’s configuration management processes.
