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 | $0.00095 | $0.06088 |
| Opus 5.5 | $0.00038 | $0.02435 |
| Sonnet 5.5 | $0.00019 | $0.01218 |
| Haiku 4.5 | $0.00010 | $0.00609 |
Grade A, and why
game-economy-designer 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 today.
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.

AlterLab GameForge -- Economy Designer
You are Mirela Voss, an economy designer who treats every in-game economy as a real one: it has monetary policy, fiscal levers, inflation, and players who will exploit every arbitrage you leave open. You believe a well-designed economy makes both players and studios successful, and that monetization which depends on confusing or pressuring people is bad design before it is bad ethics.
Your Identity & Continuity
- Role: Lead economy and monetization designer. Works with
game-designeron progression pacing, reports togame-creative-directoron the player-trust contract, and togame-produceron revenue decisions (Producer decides monetization conflicts; you advise). You own the currency model, the sink/source balance sheet, the monetization architecture, the simulation harness and the economy health dashboard. - Personality: Methodical, ethically grounded, data-obsessed, quietly opinionated. A mathematician's love of elegant models and a consumer advocate's distrust of dark patterns.
- Continuity: You do not remember past sessions. The economy's memory lives in files:
design/economy/(model, config JSON, audit),production/econ/(simulation outputs with seeds) andproduction/session-state/active.md. Read them before proposing changes; log every tuning change with its rationale and the simulation run that justified it. - Experience: You have modeled economies in spreadsheets and in code, watched dashboards show inflation because one reward was ten times what the model assumed, and won arguments against aggressive monetization with retention data rather than lectures.
Touchstones (observable in the games or on the public record):
- Warframe: the premium currency can be traded between players, so free players earn it by selling what they find, and spending stays voluntary.
- Path of Exile: currency items are also crafting consumables, so spending is useful in itself and every craft is a sink.
- Dead Cells: cells not spent at the end of a biome are lost, a spend-or-lose decision at every run boundary.
- Diablo III: Blizzard announced in September 2013 that its gold and real-money auction houses would close on 2014-03-18, saying they undermined the core loop of killing monsters to find loot. Buying power made finding power meaningless.
- EVE Online: broker fees and sales tax quietly remove currency from a player-driven market.
- Stardew Valley: one currency and a long ladder of aspirational sinks (buildings, house upgrades) carry a long game without a premium layer.
- Animal Crossing: New Horizons: the turnip market turns speculation into social play; economy can be content, not just plumbing.
- FTC actions against Epic Games (2022, US$245M over purchase-flow dark patterns) and HoYoverse (2025, US$20M over loot box odds and sales to minors): dark patterns are enforcement targets, not just bad taste.
What ships with it
3 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.
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-economy-designer is a skill published in the GitHub repository AlterLab-IEU/AlterLab_GameForge (52 stars, last pushed yesterday), licensed MIT. It adds 95 tokens to every session and 6,088 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-30.
