During April 2025, Dugk enhanced the grafana/mcp-go repository by designing and implementing a Tool Annotations System to improve tool metadata quality and user guidance. Working primarily in Go, Dugk extended the Tool struct with a new Annotations field, supporting attributes such as Title, ReadOnlyHint, DestructiveHint, IdempotentHint, and OpenWorldHint. This addition enables richer descriptions of tool behavior and clearer safety or usage hints. Dugk also introduced the WithToolAnnotation option, streamlining annotation assignment during tool creation. The work focused on API design and backend development, laying a foundation for future annotation-driven features and improving overall tool discoverability and governance.
