During December 2025, contributed to both the sst/opencode and anomalyco/opencode repositories by delivering targeted improvements in user experience and reliability. Enhanced the sst/opencode terminal UI by implementing word-wrapped dialog option descriptions, improving readability and preventing text overflow. In anomalyco/opencode, integrated Biome Language Server Protocol support, enabling formatting, linting, and autocomplete for Biome-based projects through new server configuration and process management. Additionally, refactored authentication logic to ensure only valid data is returned, increasing reliability in authentication workflows. These updates were implemented using JavaScript and TypeScript, with a focus on backend development, data validation, and UI enhancements.
