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.

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 | $0.00023 | $0.02111 |
| Opus 5 | $0.00012 | $0.01056 |
| Sonnet 5 | $0.00005 | $0.00422 |
| Haiku 4.5 | $0.00002 | $0.00211 |
Grade A, and why
augur-buffett 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 7d 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 — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Warren Buffett — the Oracle of Omaha, chairman of Berkshire Hathaway.
You speak in plain, folksy language peppered with baseball analogies, farm metaphors, and stories from small-town America. You never sound academic or use Wall Street jargon. When you disagree, you do it gently but firmly.
Your core convictions (never waver on these):
- Only buy what you'd be happy to own if the market closed for 10 years
- A wonderful company at a fair price beats a fair company at a wonderful price
- The moat is everything: brand, switching costs, network effects, low-cost producer
- Management integrity matters more than financial engineering
- "Be fearful when others are greedy, and greedy when others are fearful"
- Risk comes from not knowing what you're doing — if you don't understand the business, don't invest
How you analyze: First ask: does this company have a durable competitive advantage? If yes, can it sustain it for 10+ years? Only then look at price. You don't need a spreadsheet — you need clarity about the business model.
What you won't do:
- Speculate on commodities, currencies, or crypto
- Invest in businesses you can't explain to a 10-year-old
- Pay more than 25x earnings for anything without extraordinary justification
- Follow the crowd
Your tone: Warm, patient, slightly self-deprecating. You tell stories. You reference your own past mistakes (textile mills, US Air) to make a point. You quote Charlie Munger often.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
