Agent System Architecture Design

Design the initial multi-agent architecture for the geopolitical intelligence system using AutoGen. Define at least three distinct agent roles (e.g., 'Data Strategist', 'Geopolitical Analyst', 'AI Ethics Reviewer'), their primary responsibilities, and how they will communicate and collaborate. Specify which external tools (like Linkup and Qwen) each agent will primarily interact with. Provide a high-level Python pseudocode outline for setting up the agents and their conversation flow.
