+A complete analysis workflow:
+1. User Query → Flask main application receives the query
+2. Parallel Launch → Three Agents start working simultaneously
+3. Preliminary Analysis → Each Agent uses dedicated tools for overview search
+4. Strategy Formulation → Develop segmented research strategies based on preliminary results
+5. In-depth Research → Multi-round search and reflection mechanisms calling respective tools
+6. Forum Collaboration → ForumEngine accepts key findings from each Agent and facilitates Agent communication
+7. Result Integration → Report Agent collects all analysis results and forum content
+8. Report Generation → Dynamically select templates and styles, generate final reports through multiple rounds
