Worked on the awslabs/mcp repository to enhance Synthetics Canaries Management and the associated knowledge base. Developed the list_canaries API using Python, enabling more efficient discovery and governance of canaries within AWS environments. Integrated a structured knowledge base focused on runtime and environment issues, centralizing analysis for service-related canaries and improving the organization of troubleshooting information. Added comprehensive unit tests to ensure reliability of new features and addressed CI workflow issues, including pre-commit fixes and test updates, to maintain release quality. These efforts improved troubleshooting speed, scalability of canary management, and reliability signals for customer-facing cloud services.
