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 | $0.00042 | $0.04189 |
| Opus 5 | $0.00021 | $0.02094 |
| Sonnet 5 | $0.00008 | $0.00838 |
| Haiku 4.5 | $0.00004 | $0.00419 |
Grade A, and why
game-theory 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.

🎯 Game Theory for Business Strategy (게임이론 전략 분석)
Analyze competitive interactions, predict rival behavior, and design winning strategies using game theory frameworks.
1. Core Concepts (핵심 개념)
Every strategic interaction can be decomposed into five elements:
| Element | Description | Example |
|---|---|---|
| Players (플레이어) | Decision-makers in the game | Firms, regulators, customers |
| Strategies (전략) | Available actions for each player | Price high/low, enter/stay out |
| Payoffs (보수) | Outcomes for each strategy combination | Profit, market share, reputation |
| Information (정보) | What each player knows when deciding | Costs, demand, rival's move |
| Equilibrium (균형) | Stable outcome where no one wants to deviate | Nash Equilibrium |
Information Types
- Perfect information (완전정보): All previous moves are observable (chess)
- Imperfect information (불완전정보): Some moves are hidden (poker)
- Complete information (완비정보): All payoffs are common knowledge
- Incomplete information (불완비정보): Some payoffs are private (costs, willingness to pay)
2. Classic Games (고전 게임)
2.1 🔒 Prisoner's Dilemma (죄수의 딜레마)
The most famous game in theory. Individual rationality leads to collective irrationality.
Player B
Cooperate Defect
┌───────────┬───────────┐
Cooperate │ (3, 3) │ (0, 5) │
Player A ├───────────┼───────────┤
Defect │ (5, 0) │ (1, 1)* │
└───────────┴───────────┘
* = Nash Equilibrium
Dominant strategy: Both defect, even though mutual cooperation yields higher payoffs.
Business applications:
- Price wars (가격전쟁): Two firms cutting prices until margins collapse
- Advertising arms races (광고 경쟁): Both spend heavily, neither gains share
- R&D investment: Overinvest to avoid falling behind
- Environmental compliance: Pollute if rival pollutes (race to the bottom)
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.

game-theory is a skill published in the GitHub repository ironyjk/strategy-frameworks (11 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 4,189 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
