Richard Retanubun enhanced the zephyrproject-rtos/openthread repository by implementing a Neighbor Table CLI feature that introduces a Link Quality In (LQ In) column. Using C++ and focusing on CLI development and testing, he updated the neighbor table output and processing logic to display LQ In data, allowing both router and non-router nodes to assess connectivity with their neighbors. This targeted code change improved network visibility and troubleshooting by aligning neighbor information with router-info data. Richard validated the enhancement with focused testing and delivered it as a single, low-risk commit, demonstrating careful attention to code quality and minimal impact on existing functionality.
