What it is
A collection of 22 agent skills that turn the methods of Buffett, Munger, Duan Yongping and Li Lu into structured research workflows for Claude Code and Codex. Skills cover company deep dives, earnings reviews, industry screening, valuation, portfolio review and thesis tracking, with team skills that run four persona agents in parallel and then combine their views. Python helpers verify figures such as market cap using exact decimal math. Individual investors who want repeatable, opinionated stock research from an AI agent can install it, and a companion site publishes thousands of generated reports.
