What it does

Aeja Robustness is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when an American Economic Journal: Applied Economics (AEJ: Applied) manuscript's headline estimate must be shown to survive specification, sample, and inference choices before submission or in an R&R. Builds the robustness suite a sophisticated referee expects; it does not establish the primary identification (aeja-identification) or format the exhibits (aeja-tables-figures).

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Econometrics and empirical research. 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.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Lock the primary specification first. Everything else is a perturbation around it; do not present five co-equal specs and let the reader…
  2. One threat → one check. A robustness table should read as "here is the worry, here is the evidence it is not a problem."
  3. Show stability, not just significance. The persuasive object is that the point estimate barely moves, not that it stays starred.
  4. Be honest about where it weakens. A check that shifts the estimate is information; report it and bound the implication rather than hiding…
  5. Match inference to the data structure (clustering, spatial dependence, few clusters) — wrong SEs are the most common AEJ: Applied…

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

Aeja Robustness loads about 1.7k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 756 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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 an American Economic Journal: Applied Economics (AEJ: Applied) manuscript's headline estimate must be shown to survive specification, sample, and inference choices before submission or in an R&R. Builds the robustness suite a sophisticated referee expects; it does not establish the primary identification (aeja-identification) or format the exhibits (aeja-tables-figures).

Robustness Suite (aeja-robustness)

When to trigger

  • The main estimate is in hand and you need to show it is not an artifact of one specification
  • A referee asks "is this robust to [alternative controls / sample / functional form / inference]?"
  • The result depends on a bandwidth, a clustering choice, or a sample-selection rule that could be questioned
  • You suspect specification-search concerns and want to pre-empt them

The AEJ: Applied robustness bar

AEJ: Applied referees probe whether the headline number is stable, honestly inferred, and not the product of researcher degrees of freedom. Robustness here is not a wall of regressions — it is a targeted set of checks each tied to a specific threat to the design. Map every plausible objection to the one check that answers it, and report the checks so the reader sees the estimate barely moves.

Threat to the resultThe check that answers it
Omitted confoundersOster δ / coefficient-stability bounds; added controls in steps
Specification searcha specification curve / multiverse; pre-registered primary spec
Functional formlevels vs logs, alternative outcome definitions, nonparametric version
Sample selectiondrop influential units, alternative inclusion rules, balanced vs unbalanced panel
Inference too narrowclustered SEs at the right level, wild-cluster bootstrap (few clusters), randomization inference
Design-specific fragilityDID: honest-DID bounds; RD: bandwidth/donut; IV: weak-IV-robust set
Multiple outcomes/subgroupsRomano–Wolf / List–Shaikh–Wooldridge MHT adjustment

Robustness craft

  1. Lock the primary specification first. Everything else is a perturbation around it; do not present five co-equal specs and let the reader guess which is preferred.
  2. One threat → one check. A robustness table should read as "here is the worry, here is the evidence it is not a problem."
  3. Show stability, not just significance. The persuasive object is that the point estimate barely moves, not that it stays starred.
  4. Be honest about where it weakens. A check that shifts the estimate is information; report it and bound the implication rather than hiding it.
  5. Match inference to the data structure (clustering, spatial dependence, few clusters) — wrong SEs are the most common AEJ: Applied robustness failure.

Execution bridge (StatsPAI / Stata MCP)

Run the battery, don't just enumerate it. Full map: execution-with-mcp. AEJ: Applied is applied microeconomics — labor, health, education, and development field settings where a clean research design is the entry ticket.

  • Many outcomes / specifications: romano_wolf (step-down FWER, accounts for cross-test correlation) or benjamini_hochberg — report the adjusted threshold.
  • OVB sensitivity: oster_delta / sensemakr — the confounder strength that would overturn the headline.
  • Inference: wild_cluster_bootstrap (few clusters), twoway_cluster / conley.
  • Re-fit off one handle: audit_result(result_id) lists the missing checks and the exact suggest_function for each — no guessing the battery.
  • Exhibits: etable / did_summary_to_latex from the handle — no retyped numbers.

Keep the decisive checks in the body and the exhaustive (now actually-run) battery in the appendix. See the executed chain in the JF execution walkthrough.

Checklist

  • Primary specification declared (ideally pre-registered) before perturbations
  • Each robustness check mapped to a specific threat, not added for volume
  • Coefficient-stability evidence (Oster δ or stepwise controls) for selection-on-unobservables
  • Inference stress-tested: correct clustering level + wild-cluster/randomization inference where relevant
  • Design-specific sensitivity included (honest-DID / RD bandwidth / weak-IV set)
  • Multiple-hypothesis adjustment if many outcomes/subgroups
  • Stability of the point estimate shown, and any check that moves it reported honestly

Anti-patterns

  • A 20-column robustness table with no map from check to threat ("kitchen-sink robustness")
  • Reporting only that significance survives while the point estimate wanders
  • Hiding the specification that breaks the result
  • Clustering at the wrong level or ignoring few-cluster bias, then claiming robustness
  • Treating "added more controls and it survived" as sufficient for selection on unobservables
  • Subgroup p-hacking with no MHT correction

Worked vignette (illustrative)

An IV estimate of the return to a training program is 0.11 (s.e. 0.04). The robustness suite: (i) effective F of 23 rules out weak instruments; (ii) the Anderson–Rubin 95% set is [0.04, 0.19], so inference is not weak-IV-fragile; (iii) Oster δ implies selection on unobservables would need to be 1.8× selection on observables to nullify it; (iv) wild-cluster bootstrap with 14 clusters keeps the CI away from zero; (v) dropping the largest region moves the estimate to 0.10. The point estimate barely moves — the AEJ: Applied target.

Referee pushback mapped to the robustness fix

  • "This looks like specification search." → Declare the pre-registered or primary spec; show a specification curve in which the point estimate barely moves.
  • "Did you cluster correctly?" → Cluster at the assignment level; with few clusters report a wild-cluster bootstrap or randomization-inference p-value.
  • "Could selection on unobservables explain this?" → Report Oster δ; state how strong selection on unobservables would have to be (relative to observables) to nullify the result.
