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

multiplayer-dynamics-audit 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.

Multiplayer Dynamics Audit

Multiplayer moves the source of challenge from designed systems to other minds. That buys endless depth for free (humans adapt forever) and imports every destructive behaviour humans bring. This skill audits the strategic layer between players and the social layer around them, in designs and repos.

Core concepts

Game theory describes the strategic skeleton. Where one choice beats another regardless of what the opponent does, players converge on it and the interaction dies; a Nash equilibrium nobody wants to leave can make a whole mode stale. Healthy competitive designs avoid single stable answers by making the best choice depend on the opponent's choice.

Circular counters keep prediction alive. Rock-paper-scissors structures (and their asymmetric-payoff cousins) force mixed strategies: no pure option is safe, so players must randomise and read. Payoff asymmetry tunes how often each option should appear; a counter that wins little while risking much will vanish from play even though it "exists".

Yomi is the skill of reading the opponent. Layered prediction (I know that you know that I know) is the deepest well in multiplayer design, and it only opens when three conditions hold: players make choices the opponent can partially observe or infer, choices resolve against each other, and no option dominates. Designs that hide everything kill reads; designs that reveal everything kill mixups.

Destructive behaviour is a design problem before a moderation problem. Griefing, kill stealing, spawn camping, team-damage abuse, rage quitting, and stat padding are all behaviours some mechanic makes possible and some incentive makes attractive. Audit both halves: what the systems permit and what the reward structure quietly encourages. Divergent goals within a team (one player farming score while four push the objective) come from misaligned rewards, so fix the rewards, not the players.

Skill differentials dominate the experience. A modest gap between players collapses the interesting strategy space: the weaker player loses every exchange regardless of choice, which is a failure trap wearing a scoreboard. Tools: matchmaking on measured skill, asymmetric roles that let differently skilled players contribute, comeback mechanics with real but bounded force, handicaps players choose, and match lengths short enough that a stomp ends quickly.

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.
