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 | $0.00089 | $0.01129 |
| Opus 5 | $0.00044 | $0.00564 |
| Sonnet 5 | $0.00018 | $0.00226 |
| Haiku 4.5 | $0.00009 | $0.00113 |
Grade A, and why
econ-market-structure 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.

Market Structure Analysis
Overview
Market structure determines how firms compete, set prices, and earn profits. The four structures — perfect competition, monopolistic competition, oligopoly, monopoly — predict increasingly different behaviors as concentration rises and differentiation increases.
Framework
IRON LAW: Structure Determines Behavior, Not Vice Versa
Classify the market structure FIRST based on structural characteristics
(number of firms, barriers, differentiation), THEN predict behavior.
"This company charges high prices" does not mean it's a monopoly —
high prices can occur in oligopolies and even monopolistic competition.
The Four Structures
| Feature | Perfect Competition | Monopolistic Competition | Oligopoly | Monopoly |
|---|---|---|---|---|
| Firms | Very many | Many | Few | One |
| Product | Homogeneous | Differentiated | Homogeneous or differentiated | Unique, no close substitutes |
| Entry barriers | None | Low | High | Very high |
| Price power | None (price taker) | Some (limited by substitutes) | Significant (interdependent) | Full (price maker) |
| Long-run profit | Zero (economic) | Zero (economic) | Positive possible | Positive |
| Examples | Agricultural commodities, forex | Restaurants, clothing | Airlines, telecom, auto | Utilities, patents |
Classification Steps
- Count sellers: How many significant firms serve this market?
- Assess differentiation: Are products identical or differentiated?
- Evaluate entry barriers: Can new firms enter easily?
- Check interdependence: Do firms react to each other's moves?
Behavior Predictions by Structure
Perfect Competition: Price = marginal cost. Firms are price takers. No advertising needed. Long-run economic profit = 0.
Monopolistic Competition: Short-run profits possible through differentiation. Long-run: entry erodes profits to zero. Firms compete on brand, quality, location.
What ships with it
2 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-market-structure is a skill published in the GitHub repository asgard-ai-platform/skills (228 stars, last pushed 3mo ago), licensed MIT. It adds 89 tokens to every session and 1,129 once invoked, about $0.0004 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.
