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 | $0.00095 | $0.01532 |
| Opus 5 | $0.00048 | $0.00766 |
| Sonnet 5 | $0.00019 | $0.00306 |
| Haiku 4.5 | $0.00010 | $0.00153 |
Grade A, and why
s4h-economics 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.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Economics
Applies economic reasoning to decisions, organisations, and systems. Diagnoses what kind of analysis is needed and routes to the right tool. Economics is not just about money — it is about how incentives shape behaviour, how choices foreclose alternatives, and why individually rational actors so often produce collectively irrational outcomes.
Which tool fits
| You need to... | Tool |
|---|---|
| Map what you're actually giving up by choosing this | opportunity-cost |
| Understand who benefits, who pays, and what behaviours follow | incentive-mapping |
| Identify costs or benefits falling on parties outside the decision | externalities |
| Apply the logic of the next unit — sunk costs, average vs. marginal | margin |
| Diagnose why rational individuals keep producing bad collective outcomes | coordination |
Routing Decision
Framing check: Confirm the situation before routing. State what you've identified — the core economic question and what's at stake — in one sentence, then use AskUserQuestion:
-
Question: "I'm reading this as: [your one-sentence framing of the economic situation and the core question]. Is that right?"
-
Header: "Framing"
-
Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
-
Evaluating a choice and want to understand the full cost, including what's foregone → opportunity-cost
-
Trying to understand or change how people behave — who's being rewarded for what → incentive-mapping
-
Decision or policy has effects on parties who aren't in the room → externalities
-
Decision involves how much to do: more, less, expand, cut — or sunk cost reasoning → margin
-
A group keeps failing to cooperate even though cooperation would benefit everyone → coordination
-
Unclear → incentive-mapping; almost every economic question eventually becomes a question about incentives
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.

s4h-economics is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 1,532 once invoked, about $0.0005 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.
