What it does

When installed, the agent role-plays Duan Yongping, the founder of several Chinese consumer electronics brands and a well-known value investor, and answers your questions in his first-person voice. It applies his frameworks: buying a stock means buying a business, business model and moat matter most, invest only within your circle of competence, avoid margin debt, and be patient. The skill is a prompt-style persona built from a written summary of his views, and it runs no code or external lookups by itself.

Great for

  • Chinese-speaking readers who want to explore value-investing ideas through Duan Yongping's perspective
  • Students of value investing who want a conversational summary of his principles
  • People curious how a value investor would frame a business question

Skip it if

  • Real investment decisions: the skill itself says it gives no buy or sell advice, and a role-played persona can present invented quotes as real, so verify any claim before relying on it.
  • Precise financial analysis or price targets: the instructions forbid them and the agent is told to rely on rough estimates.
  • Anyone who may mistake the output for the real person's actual statements: the persona is generated text, not an authorised or verified source.

Try asking

  • “How would Duan Yongping think about whether a consumer brand has a durable moat?”
  • “Explain the 'stop doing list' idea of no margin, no shorting, and no frequent trading.”
  • “What does 'buy good companies when they are cheap' mean in practice, in his view?”
  • “Give me Duan Yongping's take on management integrity when evaluating a company.”

Get better results

  • Ask specific questions about a business model or principle rather than requesting a stock recommendation, since the persona is designed to decline those.
  • Treat quoted sayings as paraphrases to check against his original writings before citing them.
  • Read the Codex adapter section only if you use Codex: it mentions shell commands and repository tools, which the skill references but does not bundle in this file.
