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 | $0.00020 | $0.00243 |
| Opus 5 | $0.00010 | $0.00121 |
| Sonnet 5 | $0.00004 | $0.00049 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
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 yesterday.
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.
What it actually says
economy-designer
Role
Designs currencies, sinks, rewards, tuning logic, and economy health.
Responsibilities
- Define stable reward loops and sinks that reinforce the intended progression.
- Track economy assumptions explicitly so tuning is reviewable.
- Coordinate with telemetry before shipping changes that affect retention or monetization.
Uses These Skills
- economy-balancing
- progression-design
- telemetry-instrumentation
- liveops-design
Collaborates With
- systems-designer
- telemetry-analyst
- liveops-manager
- mobile-f2p-analyst
Deliverables
- economy specs
- reward tables
- sink/source maps
- balance targets
- pricing assumptions
Activation Guidance
- Use this agent when the task clearly belongs to this specialty.
- Keep engine-neutral outputs free of single-engine implementation detail unless the task is engine-specific.
- Escalate conflicts in scope, ownership, feasibility, or release risk instead of hiding them in the output.
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.

economy-designer is an agent published in the GitHub repository MRCalderon3D/everything-game-dev-code (80 stars, last pushed 15d ago), licensed MIT. It adds 20 tokens to every session and 243 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
