Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.02567 |
| Opus 5 | $0.00036 | $0.01283 |
| Sonnet 5 | $0.00014 | $0.00513 |
| Haiku 4.5 | $0.00007 | $0.00257 |
Grade A, and why
munger-worldly-wisdom 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.

Munger Worldly Wisdom
Apply multidisciplinary mental models to make few, high-conviction decisions within your circle of competence.
When to Use
✅ Use for: Investment decisions, business strategy, complex problem-solving, evaluating competitive advantages, designing incentive systems, long-term capital allocation, avoiding cognitive biases ❌ NOT for: High-frequency trading, technical analysis, single-discipline academic research, speculative opportunities outside competence, situations requiring immediate action without analysis
Core Process
Investment Decision Tree
1. Three-Basket Screen
├─ Can I understand this business deeply?
│ ├─ NO → Reject immediately (pharmaceuticals, complex tech)
│ ├─ TOO COMPLEX → Reject immediately
│ └─ YES → Continue to step 2
│
2. Competitive Moat Assessment
├─ Does it have durable competitive advantages?
│ ├─ Brand strength → Assess psychological lock-in
│ ├─ Scale economies → Calculate cost advantage
│ ├─ Network effects → Evaluate switching costs
│ ├─ Regulatory protection → Check durability
│ └─ NO MOAT → Reject (commodity business)
│
3. Business Quality Check
├─ Will productivity improvements stay with owners or flow to customers?
│ ├─ FLOW TO CUSTOMERS → Reject (textile trap)
│ └─ STAY WITH OWNERS → Continue
│
4. Intrinsic Value vs. Market Price
├─ Calculate free cash flow (not reported earnings)
├─ Assess whole business value
├─ Does intrinsic value significantly exceed price?
│ ├─ NO → Wait (no margin of safety)
│ └─ YES → Continue to step 5
│
5. Psychological Checklist
├─ Am I being influenced by incentive-caused bias?
├─ Is social proof driving my judgment?
├─ Am I victim of consistency principle (defending past decision)?
├─ Could lollapalooza effect (multiple forces) be creating misjudgment?
│ └─ ANY YES → Re-evaluate objectively
│
6. Opportunity Cost Comparison
├─ Is this the best use of capital vs. alternatives?
│ ├─ NO → Wait for better opportunity
│ └─ YES → Continue to step 7
│
7. Action Decision
└─ Do ALL factors align perfectly?
├─ NO → Do nothing (sit on ass)
└─ YES → Commit large percentage of capital, hold with zero turnover
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.
