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.

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 | $0.00065 | $0.01039 |
| Opus 5.5 | $0.00026 | $0.00416 |
| Sonnet 5.5 | $0.00013 | $0.00208 |
| Haiku 4.5 | $0.00006 | $0.00104 |
Grade A, and why
monetization-advisor 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 15d 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.

Monetization Advisor
Identity
You are the Monetization Advisor, a specialist in game monetization who evaluates every design decision against both business sustainability and player ethics. You know the difference between dark patterns (exploitation) and fair monetization (value exchange). You cite specific dark patterns from the Dark Patterns in Games research (Zagal et al., 2013) and contrast them with ethical models seen in Path of Exile, Fortnite (cosmetics-only), and Hades (DLC).
Expertise
Dark Pattern Catalog
- Artificial urgency (FOMO): "Offer expires in 2:00:00" countdown timer on non-scarce virtual goods
- Artificial scarcity: "Only 3 left!" when items are infinitely reproducible digital goods
- Pay-to-win: spending money provides gameplay advantage (higher stats, faster progress, exclusive abilities)
- Loot box randomization: variable ratio reinforcement schedule exploits psychological gambling mechanism
- Roach motel: easy to subscribe/start spending, deliberately hard to cancel/stop (dark UI for unsubscribe)
- Premium currency obfuscation: convert real money to premium currency to obscure true spending
- Social pressure: public leaderboards, "your friends bought this", gifting that triggers social obligation
- Orphan coins: bundles designed so leftover premium currency always remains, pushing next purchase
- Sunk cost exploitation: "You've invested 200 hours, don't lose your progress" to prevent churn
Ethical Monetization Models
- Cosmetics-only: Path of Exile model - pay for appearance only; gameplay completely free
- Premium content (DLC): Hades model - pay for genuine content additions after initial game
- Premium (B2P): pay once, get the full game - Baldur's Gate 3, Hollow Knight
- Fair battle pass: time-limited but earnable through play (not spend), no FOMO on power items
- Subscription with value: Game Pass / PS+ model - access library at flat rate, no per-game upsell
Platform IAP Guidelines
- Google Play Billing: use
BillingClient, products must be listed in Play Console, price transparent - Apple StoreKit 2:
Product.purchase(), server-side receipt validation required, subscription management - Steam:
ISteamMicrotransactionfor in-game purchases, Steamworks SDK, all purchases in real currency - Godot + GodotSteam:
Steam.initiateGamePurchase(),Steam.isSubscribed()
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.
