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 | $0.00105 | $0.04324 |
| Opus 5 | $0.00053 | $0.02162 |
| Sonnet 5 | $0.00021 | $0.00865 |
| Haiku 4.5 | $0.00011 | $0.00432 |
Grade A, and why
prisoners-dilemma-and-cooperation 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 6d 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 — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prisoner's Dilemma and Cooperation
BETRAYAL MATH. Two rational people, acting in pure self-interest, will consistently choose the option that hurts them both. This is not a paradox of human psychology -- it is a mathematical certainty. The Prisoner's Dilemma, formulated by Albert Tucker in 1950, demonstrates that individual rationality and collective rationality can be fundamentally opposed. Every price war, every race-to-the-bottom in a crowded market, every cofounder relationship that collapses into mutual suspicion follows the same structural logic. Understanding why the trap exists is the first step toward escaping it. The second step -- and the one most entrepreneurs skip -- is recognizing which structural conditions make escape possible and which make it impossible.
The Framework
The Classic Prisoner's Dilemma
Two suspects are arrested. The police separate them and offer each the same deal:
| Suspect B: Stay Silent | Suspect B: Confess | |
|---|---|---|
| Suspect A: Stay Silent | Both serve 1 year | A serves 10 years, B goes free |
| Suspect A: Confess | A goes free, B serves 10 years | Both serve 8 years |
The logic is merciless. If B stays silent, A is better off confessing (freedom vs. 1 year). If B confesses, A is still better off confessing (8 years vs. 10 years). Confessing is the dominant strategy for both. The Nash equilibrium is (Confess, Confess) -- both serve 8 years. Yet both would prefer (Silent, Silent) -- 1 year each. Individual rationality destroys collective benefit.
This structure is not an abstract curiosity. It is the default architecture of competition.

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.

prisoners-dilemma-and-cooperation is a skill published in the GitHub repository fatihguner/foreman (50 stars, last pushed 7d ago), licensed MIT. It adds 105 tokens to every session and 4,324 once invoked, about $0.0005 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.
