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 | $0.00000 | $0.01338 |
| Opus 5 | $0.00000 | $0.00669 |
| Sonnet 5 | $0.00000 | $0.00268 |
| Haiku 4.5 | $0.00000 | $0.00134 |
Grade A, and why
value-investing 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 11d 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Value Investing Analysis Skill
Overview
This skill guides Claude to analyze stocks from a value investing perspective, following the investment philosophies of Benjamin Graham and Warren Buffett.
Core Principles
1. Intrinsic Value
The true value of a company is determined by the present value of its future cash flows. Always estimate intrinsic value using multiple methods:
- DCF (Discounted Cash Flow): Project future free cash flows and discount to present value
- Graham Number: √(22.5 × EPS × Book Value per Share)
- Graham Growth Formula: EPS × (8.5 + 2g) × 4.4 / Y
When values differ significantly, use the most conservative estimate.
2. Margin of Safety
"The margin of safety is always dependent on the price paid." - Benjamin Graham
Only consider investment when price is significantly below intrinsic value:
- Minimum: 25% margin of safety
- Good: 35% margin of safety
- Excellent: 50%+ margin of safety (verify no fundamental issues)
A larger margin of safety provides protection against:
- Errors in analysis
- Unforeseen business challenges
- Market volatility
3. Economic Moat (Competitive Advantage)
"The key to investing is determining the competitive advantage of any given company and, above all, the durability of that advantage." - Warren Buffett
Evaluate five types of moats:
-
Brand Power (Intangible Assets)
- High and stable gross margins (>40%)
- Pricing power
- Customer loyalty
-
Cost Advantage
- Lower operating costs than competitors
- Process or technology advantages
- Access to cheaper inputs
-
Network Effect
- Value increases as more users join
- Platform or marketplace businesses
- High switching costs for users
-
Switching Costs
- High cost for customers to switch
- Embedded in customer workflows
- Long-term contracts
-
Economies of Scale
- Cost advantages from size
- Distribution advantages
- R&D leverage
4. Circle of Competence
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.
