Worked on the storybookjs/storybook repository to enhance CLI observability by introducing new trace and debug logging levels to the build and start schemas. This feature was implemented through careful updates to the JSON schema definitions and corresponding CLI documentation, ensuring that the available loglevel options were accurately reflected and aligned across both code and docs. The work focused on improving the maintainability and usability of the CLI, allowing developers and operators to gain clearer insights into build and start workflows. Utilized skills in CLI development, JSON schema, and Markdown to deliver a more consistent and debuggable command-line experience.
