Contributed to the jaywcjlove/awesome-mac repository by enhancing the API client tools catalog, specifically adding Echolon, an open-source Postman alternative, to the project’s README. Focused on improving documentation quality and tool discoverability, the work centered on Markdown-based documentation and open source collaboration practices. The update provided developers with broader API tooling options while maintaining clear attribution through co-authored commits. No bug fixes were addressed during this period, as the primary emphasis was on feature delivery and preparing the groundwork for future catalog expansion. The contribution supported repository health and usability, aligning with best practices in API development and documentation.
