Developed a new JSON output feature for the cognitedata/toolkit repository, enabling the cdf modules list command to produce machine-readable results for automated workflows. Focused on command line interface development and data serialization using Python, the work introduced a --format json flag that eliminates reliance on Rich tables, thereby improving CI/CD reliability and reducing parsing errors in deployment pipelines. Unit testing ensured robust integration, while documentation and changelog updates provided clear usage guidance. This enhancement streamlines automation, minimizes manual intervention, and supports modular deployment strategies, reflecting a thoughtful approach to CLI usability and automation readiness within modern development environments.
