What it does

Skills that encode Warren Buffett's approach — moats, management quality, intrinsic value, margin of safety, circle of competence — with industry-specific playbooks, so an assistant reading a filing organises what it sees along those lines. What comes out is a framework applied, not a conclusion earned: models misread financial statements and invent figures, and buy/hold/sell is not a decision to delegate. No licence file was found. Quiet since April 2026.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
