Worked on the sst/opencode repository to enhance stability and user control in command-line agent selection workflows. Focused on front end development using React and TypeScript, the primary contribution was a targeted bug fix that ensured the agent specified via the command line remained preserved throughout UI interactions. This change addressed an issue where application logic could overwrite user selections, restoring deterministic behavior for operator-driven processes. The solution involved a minimal-risk adjustment to the agent selection path, directly improving reliability and reducing potential support issues. No new features were introduced during this period, with efforts concentrated on maintaining workflow integrity.
