AI-Berkshire: Implementing a Multi-Agent Value Investing Framework via Claude Code

A new open-source framework, ai-berkshire, leverages Claude Code and a multi-agent architecture to automate value investing research by synthesizing the methodologies of legendary investors including Warren Buffett, Charlie Munger, Duan Yongping, and Li Lu.

Architectural Overview

The ai-berkshire repository introduces a sophisticated research framework designed to transition traditional value investing principles into the AI era. Built upon Claude Code, the system utilizes a multi-agent orchestration layer to perform deep fundamental analysis, moving beyond simple data retrieval to complex qualitative synthesis.

Methodological Integration

The core strength of the framework lies in its integration of specific investment philosophies. The system is engineered to simulate the decision-making processes of four prominent value investors:

• Warren Buffett: Focus on moat analysis, sustainable competitive advantage, and long-term intrinsic value.
• Charlie Munger: Application of "latticework of mental models" and multidisciplinary thinking to avoid cognitive biases.
• Duan Yongping: Emphasis on "benfen" (doing the right thing) and a rigorous focus on business model viability.
• Li Lu: Deep-dive fundamental research and opportunistic allocation in undervalued assets.

Multi-Agent Adversarial Analysis

Rather than relying on a single LLM output, ai-berkshire employs a multi-agent parallel research approach. This architecture allows different agents to analyze the same asset through the distinct lenses of the aforementioned masters. By utilizing adversarial analysis, the framework can challenge its own hypotheses, identifying potential blind spots and refining the investment thesis through internal debate and cross-verification.

Technical Implementation

By leveraging the capabilities of Claude Code, the framework automates the pipeline of gathering financial data, analyzing corporate filings, and applying the specific heuristic filters of value investing to determine if a security meets the strict criteria of a "wonderful company at a fair price."
