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 | $0.00092 | $0.01532 |
| Opus 5 | $0.00046 | $0.00766 |
| Sonnet 5 | $0.00018 | $0.00306 |
| Haiku 4.5 | $0.00009 | $0.00153 |
Grade A, and why
"econ-behavioral" 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.
This is a copy
91% identical to econ-behavioral — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Behavioral Economics
Overview
Behavioral economics studies how psychological factors cause people to deviate from rational economic predictions. Where classical economics assumes rational actors, behavioral economics documents systematic biases and designs interventions (nudges) to improve decisions.
Framework
IRON LAW: Biases Are Systematic, Not Random
Behavioral biases are PREDICTABLE patterns, not noise. Loss aversion
doesn't sometimes make people risk-seeking and sometimes not — it
consistently makes people overweight losses relative to equivalent gains
(roughly 2:1 ratio). Use specific bias names and their documented effects,
not vague "people are irrational."
Core Concepts
Bounded Rationality (Simon): People satisfice (find "good enough") rather than optimize because cognitive resources are limited.
Prospect Theory (Kahneman & Tversky):
- Loss aversion: Losses hurt ~2x more than equivalent gains feel good
- Reference dependence: People evaluate outcomes relative to a reference point, not in absolute terms
- Diminishing sensitivity: The difference between $0 and $100 feels larger than between $1000 and $1100
Mental Accounting (Thaler): People categorize money into mental "buckets" (rent, fun, savings) and treat them differently, violating fungibility.
Framing Effect: Same information presented differently leads to different decisions. "90% survival rate" vs "10% mortality rate" — same fact, different choices.
Key Biases for Business Application
| Bias | Definition | Business Application |
|---|---|---|
| Anchoring | First number seen influences subsequent estimates | Show high "original price" before discount |
| Default effect | People stick with the pre-selected option | Opt-out > opt-in for subscriptions, organ donation |
| Social proof | People follow what others do | "1,000+ customers chose this plan" |
| Scarcity | Limited availability increases perceived value | "Only 3 left in stock" |
| Endowment effect | People overvalue what they already own | Free trials make cancellation feel like a loss |
| Present bias | People overweight immediate rewards vs future | "Start free today" > "Save money over 12 months" |
| Sunk cost fallacy | Past investments influence future decisions (shouldn't) | "I've already watched 2 hours, I should finish the movie" |
| Status quo bias | Preference for current state over change | Existing customers rarely switch, even when better options exist |
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.

"econ-behavioral" is a skill published in the GitHub repository charlieviettq/awesome-agent-skill (26 stars, last pushed 1mo ago), licensed MIT. It adds 92 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. It is 91% identical to econ-behavioral, differing in 8 lines, and is treated as a copy.
