A skill your agent uses when hardening the assumptions, results, and proof architecture of a Journal of Economic Theory (JET) paper — the theory analogue of an identification strategy.

  • Hardening the assumptions
  • SKILL.md covers When to trigger, Why this replaces a causal…, The theory checklist and Assumption-set architecture…, plus 5 more sections

What it does

Jet Identification Strategy is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when hardening the assumptions, results, and proof architecture of a Journal of Economic Theory (JET) paper — the theory analogue of an identification strategy. Make every assumption explicit and load-bearing, architect the proof so two expert referees can verify it, and defend the generality/tractability trade-off; for JET, "identification" means assumption sets and proof exposition, not a causal design.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Hardening the assumptions
  • Proof architecture of a Journal of Economic Theory (JET) paper — the theory analogue of an identification strategy

Example prompts

  • “identification”
  • “/jet-identification-strategy”

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jet Identification Strategy loads about 1.5k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 596 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when hardening the assumptions, results, and proof architecture of a Journal of Economic Theory (JET) paper — the theory analogue of an identification strategy. Make every assumption explicit and load-bearing, architect the proof so two expert referees can verify it, and defend the generality/tractability trade-off; for JET, "identification" means assumption sets and proof exposition, not a causal design.

Assumptions, Results & Proof Architecture (jet-identification-strategy)

When to trigger

  • You have a candidate theorem and need to make its assumptions and proof referee-proof
  • A referee may ask "is assumption X necessary?" or "does this hold in the general case?"
  • You are choosing between a clean special case and a more general but opaque statement

Why this replaces a causal "identification strategy"

JET is theory-first: there is no data design to identify. The credibility of a JET paper rests on assumptions that are explicit and minimal, results stated precisely, and proofs an expert can check — refereed single-blind by at least two reviewers who will verify each step.

The theory checklist

Assumptions
  • Every assumption is stated formally (domain, regularity: continuity, convexity, single-crossing, finiteness) before it is used
  • Each assumption is load-bearing — for each one, you can name the step that fails without it
  • No silent assumption smuggled into a proof (a common referee catch)
  • Necessity is addressed: a counterexample shows what breaks if a key assumption is dropped
Results
  • The main result is a clean theorem/proposition/characterization, numbered and self-contained
  • Genericity, existence, uniqueness, and comparative statics are separated into distinct statements
  • The statement says exactly what is proved — no informal "essentially" claims beyond the proof
Proof exposition
  • Proof architecture is visible: lemmas in dependency order, a one-paragraph roadmap for long proofs
  • Key step (fixed point, duality, induction, envelope/revelation argument) is named and motivated
  • Long/technical proofs moved to an appendix (thm-restate to restate); body keeps the idea
  • Notation is consistent end-to-end (referees abandon proofs they cannot parse)
Generality vs. tractability
  • The chosen level of generality is defended: a transparent special case can beat an unverifiable general one; a general result is worth it only if the proof remains checkable
  • Any restriction (finite types, two players) is flagged as a scope limit, not hidden

Assumption-set architecture (three tiers)

JET papers separate three tiers of premises; label them so referees see which is which:

  • Maintained structure — the model itself (agents, type spaces, action sets, timing). Lives in the model section as prose and definitions, not as numbered assumptions.
  • Economic assumptions — single-crossing, private values, independence, ambiguity attitudes, substitutability. Numbered A1, A2, …; each carries economic content and each earns a necessity discussion.
  • Technical regularity — compactness, continuity, measurability. Numbered last; defensible as standard, but still say which proof step uses each one.

Referee heuristic: the first thing checked is whether the theorem statement quantifies over exactly the numbered assumptions — nothing more, nothing less. A theorem invoking "the assumptions of Section 2" without numbers invites a hostile read.

Proof-spine scaffold

text
Theorem 1 (statement quantified over A1–A3 only)
 ├─ Lemma 1: existence of the auxiliary object      [uses A1, A3 (compactness)]
 ├─ Lemma 2: monotonicity / single-crossing step    [uses A2]
 │    └─ Claim 2.1: boundary case                   [where A2 binds → necessity candidate]
 ├─ Main argument: fixed point / duality / induction (named in one body sentence)
 └─ Appendix B: full proofs of Lemmas 1–2; the body keeps the roadmap paragraph + key step
Example 1 (tightness): drop A2, hold everything else fixed → conclusion fails; cite it
right after Theorem 1, not in a footnote.

Writing the tightness discussion JET-style

  • Place the counterexample immediately after the theorem as a numbered Example, with one sentence saying which assumption it targets.
  • Make it minimal: change exactly one assumption and keep the rest of the environment fixed, so the referee attributes the failure to the right premise.
  • If no counterexample is available, state openly that necessity is an open question — JET referees respect a flagged open problem more than silence.

Micro-vignette (decision theory)

A representation theorem for ambiguity-averse preferences: A1 (weak order, continuity) is regularity; A2 (certainty independence) is the economic axiom. The proof's separation argument fails exactly when A2 is weakened to independence on constants only; Example 1 exhibits a maxmin preference violating the conclusion under the weakening. One page settles A2's tier, load-bearing step, and necessity — the page both referees read first.

Anti-patterns

  • A "general" theorem whose proof silently needs finiteness or continuity
  • Assumptions introduced inside a proof rather than stated up front
  • A monolithic 6-page proof with no roadmap or lemma decomposition
  • Claiming necessity of an assumption without a counterexample

Output format

【Theorem】<precise statement>
【Assumptions】[A1 used at step __ | A2 used at __ | necessity of Ak: counterexample/general]
【Proof spine】lemmas in order → key argument named → appendix offload
【Generality call】special-case-clean | general-but-checkable | (reject) general-unverifiable
【Next】jet-contribution-framing / jet-tables-figures (schematic) / jet-rebuttal
