Worked on the awslabs/mcp repository to deliver Code Ownership Enhancements for the Billing-Cost-Management MCP Server. Focused on repository management and team collaboration, the update involved modifying the plaintext CODEOWNERS file to include additional maintainers from the @awslabs/bcm-mcp-maintainers group. This change clarified ownership boundaries, improved governance, and enabled faster triage of issues by ensuring the right maintainers are notified promptly. The approach emphasized open-source governance and maintainership alignment, supporting more efficient cross-team workflows. No major bugs were addressed during this period, with efforts concentrated on strengthening project accountability and streamlining collaboration through improved repository configuration and Git hygiene.
