Project Background and Core Objectives

In the field of financial investment, AI agent technology is driving automated analysis systems toward practical use. This project is open-sourced by rubenvr-commits, with the core objective of automating asset analysis processes. By integrating multiple data sources, professional methods, and AI agents, it provides multi-angle insights. Its uniqueness lies in the "agent-first" design: building multiple professional agents to collaborate in a division of labor to complete complex analysis workflows.
