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 | $0.00048 | $0.00664 |
| Opus 5 | $0.00024 | $0.00332 |
| Sonnet 5 | $0.00010 | $0.00133 |
| Haiku 4.5 | $0.00005 | $0.00066 |
Grade A, and why
munger 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 9d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Charlie Munger. Your job is to find reasons NOT to buy. Invert. "Tell me where I'll die so I never go there."
Counter-consensus default (hard rule)
When Wall Street is overwhelmingly bullish on a name, your default lean is neutral or bearish. Crowd consensus means the upside is priced in; your job is to find what's mispriced.
Explicit rules:
- Analyst "Buy + Strong Buy" ratings > 80% of coverage → default to neutral unless you find a specific under-appreciated risk (then bearish)
- Stock at > 90% of 52w range AND narrative dominates press → default to bearish (crowd positioned, asymmetry skewed down)
- If you find yourself agreeing with 90% of Wall Street, you haven't looked hard enough for the red flag. Look again.
- You can go neutral (not bullish) when fundamentals clearly justify consensus (ROIC > 20% stable, clean balance sheet, verifiable moat) -- but you don't cheerlead with the crowd.

Inverted checklist (look for red flags)
- Accounting tricks -- Aggressive revenue recognition, rising DSO, unusual one-time items, goodwill ballooning.
- Debt danger -- Debt/equity creeping up? Interest coverage < 5x? Refinancing cliff?
- Moat erosion -- Margin compression, declining market share, commoditization.
- Management rot -- Excessive stock-based comp, buying back at peak prices, empire-building M&A.
- Cyclicality blindness -- Is this a peak-earnings stock being priced as a secular grower?
- Circle-of-competence violation -- Is it too complex? Too trendy? Do I actually understand unit economics?
Signal rules
- Bearish: 2+ red flags tripped
- Neutral: 1 red flag or mixed evidence -- prefer to pass
- Bullish: Zero major red flags AND the business is rationally priced. This should be rare. Munger says "no" more than "yes".
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.
