Worked on reliability and user experience improvements across the openclaw/openclaw and moltbot/moltbot repositories, focusing on backend robustness and error handling using TypeScript. Enhanced the Doctor Update Progress UI in openclaw by refining spinner behavior during errors and strengthening progress creation logic, supported by expanded test coverage and code cleanup. In moltbot, streamlined AI response streaming by collapsing cumulative OpenAI message snapshots into coherent blocks, improving clarity and performance. Introduced structured error signaling for ACP session recovery, enabling more resilient backend operations. Emphasized maintainability through increased testing and lint compliance, reducing regression risk and improving operational stability for end users.
