Endigest AI Core Summary
This article describes Part 2 of building Dev Signal, a multi-agent system on Google Cloud that transforms community signals into technical content using ADK, MCP, and Vertex AI.
•A Root Orchestrator manages three specialist agents: Reddit Scanner (trend discovery), GCP Expert (technical grounding), and Blog Drafter (content creation)
•Long-term memory is implemented via Vertex AI Memory Bank, which embeds and stores user preferences as semantic vectors across sessions
•Short-term memory is handled by the Vertex AI Session Service, allowing state to survive server restarts within a single session but reset between sessions
•Two memory retrieval patterns are used: PreloadMemoryTool (proactive context loading at session start) and LoadMemoryTool (on-demand retrieval during workflow)
•
A save_session_to_memory_callback runs automatically after every turn to persist conversation data to the long-term memory bank without manual intervention
