Worked on the openclaw/openclaw repository to enhance Telegram reply delivery by integrating outbound message hooks into the reply path. This approach enabled execution of pre-send and post-send hooks, supporting custom logic and providing delivery feedback for improved transparency. Focused on ensuring that message_sent statuses accurately reflected actual delivery, which increased the reliability of delivery reporting and downstream observability. Enhanced error handling mechanisms allowed for faster remediation of delivery issues. The work was implemented using TypeScript and Node.js, leveraging skills in API integration, backend development, and event handling to deliver a more robust and transparent messaging workflow within the system.
