Developed and delivered a new Rockcraft formula for the chenrui333/homebrew-core repository, focusing on improving packaging quality and enabling a reproducible OCI image workflow. The work centered on Homebrew formula development using Ruby, with careful attention to package management best practices. By integrating dependencies, resources, and installation instructions, the formula streamlined the process of creating OCI images via Snapcraft and Charmcraft. This approach reduced setup time for developers and enhanced CI/CD reliability by standardizing packaging and documentation. No bug fixes were reported during this period, as the primary emphasis was on robust feature delivery and ensuring packaging correctness throughout.
