GOD is a control room for observing and directing societies of language-model agents running in simulated worlds. It lets researchers inspect replays, question individual agents, alter future events, reset simulations, and export experiments for reuse. The catalogue entries are skills and agents for operating and investigating these simulations.
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.

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 | $0.00036 | $0.00233 |
| Opus 5.5 | $0.00014 | $0.00093 |
| Sonnet 5.5 | $0.00007 | $0.00047 |
| Haiku 4.5 | $0.00004 | $0.00023 |
Grade A, and why
economic-reasoning 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 1mo 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.
What it actually says
Economic Reasoning
Provides economic reasoning capabilities when the agent operates in an EconomySpace environment.
What It Does
- Analyzes the agent's financial state (currency, income, consumption)
- Evaluates trading and employment opportunities based on cost-benefit analysis
- Records economic decisions and reasoning as cognition memory
When To Activate
- Observation contains financial information (currency, prices, income)
- Agent needs to make economic decisions (buy, sell, work, invest)
- Tax or policy changes affect the agent's financial situation
Data Available via Environment
The EconomySpace environment provides these tools:
get_person(agent_id)— current financial stateget_all_products()— available products and pricesbuy_product(agent_id, product_name, quantity)— purchasefind_job(agent_id)— find employment
What ships with it
1 file 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.

economic-reasoning is a skill published in the GitHub repository XiaoLuoLYG/GOD (1,235 stars, last pushed 3d ago), licensed Apache-2.0. It adds 36 tokens to every session and 233 once invoked, about $0.0001 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.
