A PolarDB-X team article describes an Agent workflow that receives alerts or tickets, gathers logs, monitoring data and other system information, reproduces defects, modifies code, adds test cases, runs regression tests, and submits the results for developer review. The team says all alerts received first-pass analysis and handling, with a first-pass coverage rate of 100%. It also says that over six months, the workflow identified and recorded more than 200 defects from over 10,000 alert-handling instances; more than 70% of the defects could be reproduced stably and were fixed by the Agent before entering code review. These operational figures are team-reported and were not independently verified in the article.
