Worked on the quarto-dev/quarto-cli repository to address a critical issue affecting LaTeX rendering workflows. Focused on improving the reliability of package management by correcting a typo in the TeX Live update command within the tlmgr utility. This fix ensured that both CI/CD pipelines and local development environments could execute package updates without encountering build failures. Leveraged skills in Command Line Interface operations and TypeScript to implement and validate the solution, emphasizing accuracy in command execution. The work contributed to a more stable development process for users relying on automated LaTeX builds, highlighting attention to detail in package management workflows.
