Taoyifan contributed to the coze-dev/coze-loop repository by building and enhancing backend observability and reliability features over four months. He developed a not_match query type for trace filtering, enabling granular exclusion of data in observability workflows using Go and SQL. Taoyifan implemented default trace duration configuration to improve trace data retention and analytics, and introduced RabbitMQ message compression with producer configuration and unit tests to optimize message queue management. He also addressed bugs in trace export and backend task processing, adding caching and improving logging efficiency. His work demonstrated depth in backend development, data filtering, and robust testing practices.

January 2026: Backend reliability and efficiency improvements in coze-loop. Addressed a critical trace export bug, added caching for non-final autotasks, and tightened time handling in the trace export service. Implemented logging efficiency enhancements to reduce runtime overhead in LogTrafficMW, lowering log noise and improving throughput.

December 2025 — coze-loop: Delivered core reliability and observability improvements. Implemented RabbitMQ message compression in the observability module with producer configuration support and added unit tests. Fixed the compression logic bug to ensure correct behavior. Stabilized backend task processing by resolving NPEs, task completion bugs, and backfill gaps. Enhanced trace data reliability by filtering invalid trace IDs during GetTrajectories. Outcomes include reduced message sizes and bandwidth, fewer runtime errors, and higher confidence in trace data integrity.

Month 2025-09 — Delivered a new not_match query type to refine observability filtering, enabling exclusion of data points containing a substring for traces and observability data. Implemented backend logic, SQL generation, and unit tests, laying groundwork for more expressive query capabilities and reduced noise in diagnostic data. No explicit major bug fixes documented this month; focus remained on feature delivery and test coverage, driving higher data quality and faster, more targeted investigations.
