Jan 1, 2026January 2026 — GoogleCloudPlatform/devrel-demos: Delivered Dynamic Metadata-driven Data Asset Discovery and Recommendation, enhancing data governance with metadata-aware asset discovery and user-query-driven recommendations while enforcing project and region constraints. The work established a structured metadata discovery and search execution flow, enabling more accurate, governance-compliant data asset recommendations and reducing manual discovery effort. A dependency fix (unrestrict ADK version) was applied to stabilise builds and broaden compatibility.

Nov 1, 2025November 2025 — Focused on building a scalable data governance foundation by integrating Dataplex metadata with Generative AI agents and tightening data handling scope. Delivered a foundational governance agent infrastructure, progressed agent/MCP integration to a working state, and enhanced prompt constraints to bolster governance safety. Fixed a critical data governance bug to ensure GEMINI processes only assets from the active project, removing cross-project data handling. These efforts increase governance accuracy, reduce risk, and establish a repeatable, business-value-driven AI data governance workflow for the DevRel demos project.
