Worked on stabilizing the Pepr format command in the defenseunicorns/pepr repository, addressing a critical issue where the command previously reported success even when ESLint or Prettier detected errors. Focused on improving reliability by ensuring the command now fails explicitly when linting or formatting errors occur, thereby reducing false positives in CI pipelines. Expanded test coverage using JavaScript and TypeScript to prevent regressions and reinforce test-driven validation. Enhanced CI/CD workflows by making command outcomes accurately reflect code quality checks. This work provided clearer feedback to developers and established a more robust foundation for future improvements in code formatting and repository health.
