repeated-games-reputation

repeated-games-reputation is a skill for Claude Code, Codex from deciqAI/knowledge-skills. It costs 118 tokens per session (2,467 once invoked), scanned A, original, MIT.

A way to understand cooperation between people or organizations that interact more than once, or whose actions are visible to others. Future consequences and reputation can make cooperation worthwhile and discourage betrayal.

In plain words
What is it for?
Use it to choose responses to broken agreements, build trust with repeat partners, design reputation systems, and assess whether a partnership can survive betrayal.
Why use it?
It explains why a short-term selfish move can damage a valuable long-term relationship. It also shows how trust can work in marketplaces where participants may not deal with each other directly.

Token cost

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.

Security

Grade A, and why

repeated-games-reputation 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 9d 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.

Repeated Games & Reputation

Overview

When parties repeat — or third parties observe — defection costs tomorrow's cooperation, flipping the Prisoner's Dilemma. Axelrod's 1979–1981 tournaments proved cooperation wins empirically; the Folk Theorem (Fudenberg & Maskin 1986) proved it mathematically. This skill diagnoses when cooperation is sustainable (discount factor check), selects the right strategy (TFT vs Generous TFT vs Pavlov), and engineers reputation infrastructure for markets where parties don't repeat directly. Composes with prisoners-dilemma · second-order-thinking · signaling-games.

When to Use

Apply when:

  • A relationship is expected to continue between the same parties (supplier-buyer, employer-employee, GP-LP, founder-investor, customer-platform)
  • Even in a one-shot direct interaction, third parties observe the move and adjust their willingness to play with you
  • You're designing a platform or marketplace that needs strangers to cooperate — reputation infrastructure is the architectural question
  • You're trying to escape a defection trap and the candidate escape is "repetition" or "reputation"
  • A partnership keeps fragmenting — diagnose whether δ is too low or observation is broken
  • Trust/safety reputation is shaping who wins AI adoption and AI-native competition — where capability converges, a bad launch or safety incident reprices every future round of enterprise adoption (and the AI capex supercycle only lengthens the shadow of the future)

When NOT to use:

  • Genuinely one-shot with no third-party observability → use prisoners-dilemma
  • Parties are about to exit (last round of finite game) — backward induction risk; standard repeated-game logic can fail
  • Zero-sum situation — repetition can entrench rivalry rather than dissolve it
  • "Repetition" is only nominal — rotating counterparties who don't talk = effectively one-shot

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.
