What is yao-gametheory-skill?

A strategy framework for decisions where competitors, partners, platforms, regulators, or other parties may react to your move. Game theory is the study of choices in situations where each side’s outcome depends on the others.

It helps produce reports about competition, negotiation, pricing, market channels, platforms, mergers, financing, alliances, and regulatory interactions.

It helps examine whether a threat, promise, alliance, price change, or other commitment is believable and how other players might respond.

yao-gametheory-skill — Skill for Claude Code and Codex by yaojingang

About the project

yaojingang/yao-open-skills is a public collection of reusable AI skills for research, decision-making, business analysis, learning, and document creation. It serves people who want repeatable, maintainable AI workflows instead of isolated prompts, and catalogued add-ons are published skills from this collection.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00101	$0.00820
Opus 5	$0.00051	$0.00410
Sonnet 5	$0.00020	$0.00164
Haiku 4.5	$0.00010	$0.00082

Security

Grade A, and why

yao-gametheory-skill 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_report_bundle.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Yao Game Theory Skill

Use This Skill For

convert CEO-facing strategic interactions into game theory reports
choose and combine game theory frameworks from references/framework-catalog.md
answer "对手可能怎么反应" and "我们的承诺动作是否可信"
use historical behavior and reference-class experience to adjust rationality and commitment probabilities
update prior reports when a player makes a new move
export synchronized Markdown, HTML, Word/DOCX, and PDF reports

Do Not Route Here

game theory homework, theorem proofs, or textbook explanation with no strategic report
generic strategy brainstorming where no player can react strategically
final legal, financial, investment, antitrust, or regulatory advice
manipulative, deceptive, coercive, or unlawful competitive tactics

Default Workflow

Convert the request with references/intake-contract.md; use references/dynamic-iteration-loop.md for incomplete input or later player moves.
Route through references/framework-catalog.md: select one primary framework and 2-4 secondary lenses.
Instantiate the combination with references/game-model-playbook.md: players, strategies, payoffs, timing, beliefs, and equilibrium logic.
Calibrate player rationality with real historical behavior and experience references before trusting payoff-matrix inference.
Test commitments and signals with references/commitment-signal-checklist.md.
Run references/strategic-hygiene-checklist.md, references/strategy-readiness-loop.md, and references/sensitivity-and-safety.md.
Build framework selection, opponent reactions, payoff matrix, historical behavior calibration, readiness, sensitivity, next information, and update triggers.
Run scripts/generate_report_bundle.py; finalize with references/strategic-report-contract.md and references/report-export-pipeline.md.

Output Contract

Produce an executive strategy report, not a theory lecture.
Put the recommendation, opponent reaction forecast, and credible-commitment call before technical sections.
Mark payoffs, probabilities, and assumptions as observed, estimated, or assumed.
Include frameworks, payoff matrix, reactions, equilibria, historical rationality calibration, commitment/signal checks, readiness, sensitivity, next information, update log, triggers, and caveats.
Default language is Simplified Chinese; generate PDF automatically when possible, otherwise keep HTML print-ready.

What ships with it

30 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
