Worked on the openclaw/openclaw repository to address a core stability issue in the Slack integration, focusing on backend development and API integration using Node.js and TypeScript. Implemented thread-level session keys to isolate Slack thread contexts, which resolved a context-mixing bug that previously caused cross-channel response inaccuracies. Tuned cache time-to-live and size parameters to enhance performance in high-traffic Slack workspaces, ensuring more reliable and scalable interactions. The work laid a technical foundation for future feature growth by improving the accuracy and efficiency of Slack responses, demonstrating a methodical approach to debugging and system optimization within a complex integration environment.
