Worked on stabilizing input event handling within the docker/cagent repository by addressing a bug in the MouseEventFilter component. Focused on ensuring that tea.MouseMsg events are correctly processed, this change reduced the likelihood of misrouted or missed mouse events, thereby improving input reliability in production environments. The solution involved a tightly scoped update to the event-filter logic, written in Go, which was carefully isolated to minimize regression risk and maintain system stability. The work emphasized maintainability through precise commit messaging and traceability, reflecting a methodical approach to back end development and bug resolution using Go and event-driven programming concepts.
