Worked on moltbot/moltbot to enhance both reliability and user experience by delivering targeted improvements in TypeScript across backend and frontend components. Addressed a critical issue in the Feishu wiki tool by implementing validation logic that treats wiki space IDs as opaque strings, preventing numeric precision loss in JavaScript and ensuring robust handling of user input. Developed comprehensive tests to verify correct rejection of numeric-looking IDs and proper acceptance of quoted IDs. Additionally, introduced a feature to preserve user input drafts during busy chat sessions, reducing accidental message sends and improving typing continuity. Demonstrated strong skills in API development and code quality.
