aeri-theory-model

aeri-theory-model is a skill for Claude Code from brycewang-stanford/Awesome-Journal-Skills. It costs 0 tokens per session (1,217 once invoked), scanned A, original, MIT.

A guide to reducing a theory or conceptual model to the smallest version needed to support one main result in a short economics paper. A model here means the assumptions and formal structure used to derive or explain that result.

In plain words
What is it for?
Use it to simplify assumptions, retain only necessary results, and move general frameworks or extensions out of the main paper.
Why use it?
It keeps technical setup from taking space away from the paper’s main finding and makes the argument easier to follow.

Token cost

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.

Security

Grade A, and why

aeri-theory-model 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.

Theory / Model — Minimal to Carry One Insight (aeri-theory-model)

When to trigger

  • A theory paper's single result (a theorem, an impossibility, a sharp comparative static) needs a tight model
  • An empirical paper carries a structural or conceptual model that has grown beyond what the result needs
  • The model section is eating the word budget that the result and identification need
  • A referee might ask "why all this machinery for one point?"

The AER: Insights modeling discipline

AER: Insights rewards a single, surprising, clean theoretical or modeling insight delivered with the smallest model that produces it. The question is never "is the framework general?" but "what is the most economical model whose one result is important and surprising?" Generality, extensions, and robustness of the modeling go to the Supplemental Appendix; the main text states the assumptions, the one key result, and the intuition. A theory paper here is short and pointed, the opposite of a foundational framework paper for AER or a field journal.

Two cases

Case 1: The paper IS the theory (a theory short paper)

  • One headline result. A single theorem, impossibility, or characterization that overturns or sharply refines a believed claim. State it early, prove it economically.
  • Minimal assumptions. Strip to the assumptions the result actually needs; flag which are substantive vs. technical.
  • Intuition before proof. Give the one-paragraph mechanism that makes the result memorable; full proofs to the appendix if long.
  • Surprise stated. Name the prior intuition the result violates — that is why it is an AER: Insights paper, not a field-theory note.

Case 2: The model SUPPORTS an empirical insight

  • Justify the model's job. It exists to deliver one object (an identifying restriction, a counterfactual, a structural parameter the data identify). Cut anything not in service of that.
  • Minimal structure for identification. Tie the key parameter to a data moment (aeri-identification Branch C); keep solution/estimation detail in the appendix.
  • One counterfactual, if any. If the structure delivers a counterfactual, report the single one that matters with its uncertainty; alternatives to the appendix.

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.
