Worked on the OpenClaw project to improve reliability by addressing a session management issue related to context token refresh during model switching. The solution involved clearing cached context tokens to maintain accurate context windows and prevent session errors caused by exceeding token limits. This fix was implemented in JavaScript and validated through targeted regression testing to ensure consistent token state across model transitions. The work focused on backend session handling within the openclaw/openclaw repository, emphasizing robust session management and thorough testing practices. Over the month, the primary contribution centered on bug resolution rather than feature development, demonstrating attention to stability and correctness.
