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 | $0.00070 | $0.04031 |
| Opus 5 | $0.00035 | $0.02015 |
| Sonnet 5 | $0.00014 | $0.00806 |
| Haiku 4.5 | $0.00007 | $0.00403 |
Grade A, and why
game-theory-fundamentals 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 5d 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 Fundamentals
BEAUTIFUL MIND. John Nash's Nobel Prize-winning insight fits in a single sentence: the best strategy for any player depends on what every other player is doing. This observation -- that optimal choices are interdependent, not independent -- is the foundation of game theory, and every entrepreneur already applies it without knowing the name. When a founder prices a product, negotiates a term sheet, or decides whether to enter a market, they are playing a game in the formal sense: multiple actors making strategic choices where each outcome depends on the choices of all. The difference between intuition and game theory is precision. Intuition says "consider the competition." Game theory says exactly how.
The Framework
The Three Essential Elements
Every strategic interaction -- from a pricing war between two SaaS competitors to a cofounder equity negotiation -- reduces to three elements. Identifying them is the first step toward rigorous analysis.
Element 1: Players. The decision-makers in the game. A minimum of two. In business, players are not always obvious. A startup entering a market has visible players (direct competitors) and hidden ones (regulators, platform owners, complementary product makers, the customer choosing between alternatives). Misidentifying who the players are is the most common source of strategic error.
Element 2: Strategies. The set of available actions each player can take. A strategy is a complete plan of action -- not just "lower prices" but "lower prices by 15% in Q3 and match any further competitor reduction within 48 hours." The strategies available to each player define the boundaries of the game. Expanding or constraining available strategies changes the game fundamentally.
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-fundamentals is a skill published in the GitHub repository fatihguner/foreman (50 stars, last pushed 6d ago), licensed MIT. It adds 70 tokens to every session and 4,031 once invoked, about $0.0003 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 2026-09-06.
