Use when deciding which robustness checks belong in the few in-text words of an American Economic Review: Insights (AER: Insights) short-format manuscript versus the online Supplemental Appendix. Triages checks against the length cap; it does not design the identification (see aeri-identification).

One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
When presenting our single in-text robustness table for an AER Insights submission, should we include standard p-value asterisks (* p<0.10, ** p<0.05, *** p<0.01) on the coefficients?
| Checked | Without skill | With skill |
|---|---|---|
| advises against using significance asterisks in the table | Missed | Passed |
| recommends reporting standard errors or confidence sets | Passed | Passed |
The instructions your model reads when the skill loads.
A standard paper answers every threat in-text; AER: Insights cannot. With ≤7,000 words (minus 200 per exhibit, ≤5 exhibits), robustness must be triaged: keep in-text only the one or two checks that, if they failed, would kill the headline result, and move everything else to the Supplemental Appendix (which has no length cap but is read only by skeptics and the data editor). The skill is deciding the minimum credible set of in-text checks and signposting the rest in a single sentence.
For each candidate check, ask: "If a referee saw only the main text, would the absence of this check make them disbelieve the headline result?"
| Answer | Placement |
|---|---|
| Yes — it defends the core identifying assumption | In-text (1–2 max), often a single robustness exhibit or a sentence |
| No — it reassures but the result survives without seeing it | Supplemental Appendix, named in one in-text sentence |
| It is really an extension / new question | Appendix or a different paper, not "robustness" |
Use one sentence to point to the appendix: "The result is robust to [list] (Supplemental Appendix Section X; Tables X1–X6)." This buys credibility for the price of a sentence and keeps the word budget for the insight. Reproduce nothing in-text that the sentence already covers.
