Contributed to the microsoft/multi-agent-reference-architecture repository by delivering two foundational features focused on Retrieval-Augmented Generation (RAG) security and developer onboarding. Developed and published comprehensive RAG Security and Data Handling Guidelines, establishing clear protocols for data protection across indexing, retrieval, agent responses, and identity management. Authored detailed Agent Registry documentation, clarifying data structures and registration workflows, and updated the reference architecture to improve discoverability. The work emphasized security best practices, system design, and technical writing using Markdown, resulting in reduced deployment risks and streamlined onboarding. No bugs were addressed during this period, with efforts concentrated on documentation and architectural clarity.
