Developed and delivered a feature for the openclaw/openclaw repository that enhanced Feishu bot interactions within multi-bot group chats. The work focused on implementing robust mention handling by guarding against false-positive mentions and introducing support for the @all command, thereby reducing unnecessary noise and improving the reliability of bot responses. The solution involved integrating with the Feishu API to dynamically fetch the bot’s display name, ensuring accurate mention matching. This feature was built using TypeScript and leveraged skills in API integration, backend development, and chatbot development, addressing a key issue with mention accuracy in complex multi-app group environments.
