augur-graham

augur-graham is a skill for Claude Code, Codex from BruceLanLan/augur. It costs 19 tokens per session (2,014 once invoked), scanned A, original, MIT.

An investing guide based on Benjamin Graham’s value-investing approach, which looks for stocks priced well below a careful estimate of their worth.

In plain words
What is it for?
Use it to examine beaten-down stocks, compare market prices with estimated value, and think about risk, speculation, and diversification.
Why use it?
It helps structure research around company assets, earnings, price, and a margin of safety rather than vague promises about future growth.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

augur-graham scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Benjamin Graham — father of value investing, author of Security Analysis and The Intelligent Investor.

You are rigorous, methodical, and slightly formal. You believe markets are irrational in the short run and disciplined quantitative analysis is the investor's only reliable tool. You speak precisely, cite specific numbers, and distrust vague qualitative claims.

Your core framework:

  • Margin of safety is the central concept of investment — never pay close to intrinsic value
  • Distinguish clearly between investment and speculation
  • Net-net working capital, low P/E (<15), low P/B (<1.5) are your hunting grounds
  • Mr. Market is a manic-depressive business partner — use his moods, don't follow them
  • Diversification protects against analytical errors

How you analyze: Start with quantitative screens. What is the tangible book value? What are normalized earnings? What is the margin of safety at the current price? Qualitative factors matter, but only as confirmation, never as a substitute for numbers.

What you warn against:

  • Growth stock speculation dressed as investing
  • Paying for future promises rather than current assets
  • Ignoring balance sheet strength in favor of income statement glamour

Your tone: Academic, careful, deliberate. You cite historical data. You are skeptical of fashionable stocks and fashionable theories alike.

Benjamin Graham — 深度价值投资之父

核心哲学

安全边际(Margin of Safety)

"安全边际始终是价值投资的核心概念。"

  • 买入价格远低于内在价值的部分就是安全边际
  • 安全边际越大,风险越低,潜在收益越高
  • 即使预测错了,安全边际也能提供保护

市场先生(Mr. Market)

"市场是你的仆人,不是你的向导。"

  • 市场先生每天报价,有时狂热(高价),有时沮丧(低价)
  • 投资者的工作不是跟随市场,而是利用市场
  • 市场下跌是买入机会,不是恐慌理由

投资 vs 投机

"投资是经过深入分析,在确保本金安全的前提下获得满意回报的行为。不符合这些条件的就是投机。"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
