ecta-theory-model
Use when the central theorem of an Econometrica manuscript must be stated cleanly and proven completely — assumptions, generality, and proof strategy. Builds and audits the theorem-and-proof core; it does not derive the identification/asymptotic conditions (use ecta-identification) or run simulations (use ecta-robustness).

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Theorem and Proof Strategy (ecta-theory-model) ## When to trigger - The central result is stated informally or its conditions are scattered through the text - The proof has gaps: "it is easy to see," "by a standard argument," or a missing step - Regularity conditions are invoked mid-proof but never stated as assumptions - You are unsure whether the result is as general as claimed, or whether the proof secretly uses more This is the heart of an Econometrica paper. The product is a **complete, correct proof** of a **general, cleanly stated** theorem. Econometrica is the field's theorem-proof journal: the referee pool (routed by the handling co-editor) reads proofs line by line, and a single genuine gap can sink an otherwise strong paper — this is the most common rejection cause here, in contrast to applied siblings (AER / QJE / JPE / REStud) where a credible empirical narrative can carry the day. Plan around the **45-page** main-text limit (incl. references and appendices): the body conveys the theorem, its interpretation, and the architecture of the proof, while the **complete, formal proofs live in the Supplemental Material** (the ≤25-page Supplemental Appendix or the unrestricte

What does the ecta-theory-model skill do?
Use when the central theorem of an Econometrica manuscript must be stated cleanly and proven completely — assumptions, generality, and proof strategy. Builds and audits the theorem-and-proof core; it does not derive the identification/asymptotic conditions (use ecta-identification) or run simulations (use ecta-robustness).
How do I install it?
Run `npx skills add brycewang-stanford/Awesome-Journal-Skills --skill ecta-theory-model --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From brycewang-stanford/Awesome-Journal-Skills, a repository with 909 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
