What it does

Pnasnexus Statistics is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use to enforce PNAS Nexus's statistics and reproducibility reporting — n and replication, test choice and assumptions, effect sizes with uncertainty, multiple-comparison control, randomization/blinding, sample-size justification, and reproducible code. Also covers whether a Registered Report (Stage 1/2) is the right route for confirmatory work.

Its SKILL.md is about 1.4k 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 Data & Analytics, covering Statistics, Experimental design and Reproducible 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.

When your agent uses it

  • Enforce PNAS Nexuss statistics and reproducibility reporting — n and replication
  • Test choice and assumptions
  • Effect sizes with uncertainty
  • Multiple-comparison control

Example prompts

  • “/pnasnexus-statistics”

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

Pnasnexus Statistics loads about 1.4k tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 579 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 to enforce PNAS Nexus's statistics and reproducibility reporting — n and replication, test choice and assumptions, effect sizes with uncertainty, multiple-comparison control, randomization/blinding, sample-size justification, and reproducible code. Also covers whether a Registered Report (Stage 1/2) is the right route for confirmatory work.

Statistics & Reproducibility (pnasnexus-statistics)

When to trigger

  • Results report P values but not effect sizes or n.
  • "Three independent experiments" is claimed but replication is unclear.
  • Multiple comparisons are run with no correction.
  • A reviewer is likely to ask "were analyses pre-specified?" and there's no answer.
  • The analysis is not reproducible from the deposited code (pnasnexus-data).
  • The study is confirmatory and you want reviews before collecting data — consider a Registered Report.

The reporting backbone (every quantitative claim)

Each claim needs: effect size + uncertainty + n + test + what n means.

  • n stated, with the unit of replication (biological vs technical replicates; cells vs animals vs subjects vs experiments).
  • Effect size with 95% CI (preferred) or SD/SEM clearly labeled — not P alone.
  • Exact P values (e.g., P = 0.013), not "P < 0.05", unless extremely small.
  • Test named and justified (assumptions checked: normality, variance homogeneity, independence).
  • Multiple comparisons corrected (Bonferroni/Holm/FDR) when many tests are run.

Replication and design

  • Distinguish biological replication (independent samples) from technical replication (re-measurement). The former is what counts.
  • State how the sample size was chosen (power analysis or explicit rationale), not post-hoc.
  • Report randomization of subjects/treatments and blinding of measurement/analysis where applicable, or state why not.
  • Report inclusion/exclusion criteria and any excluded data, with reasons, decided in advance.

Registered Reports: a PNAS Nexus route for confirmatory work

PNAS Nexus offers Registered Reports, where the study design and analysis plan are peer-reviewed before data are collected (Stage 1, ≤3 pp), and — on in-principle acceptance — the completed study (Stage 2) is published largely regardless of whether the hypothesis was supported, provided the pre-registered plan was followed.

Consider a Registered Report when:

  • The study is confirmatory / hypothesis-testing and you want to guard against p-hacking and publication bias.
  • A null or mixed result would still be informative to the field.
  • The design benefits from reviewer input before the expense of data collection.

In the Stage 2 manuscript, separate pre-registered (confirmatory) analyses from post-hoc (exploratory) ones explicitly, and report deviations from the Stage 1 plan.

Discipline-specific notes across PNAS Nexus divisions

PNAS Nexus spans biological/health/medical, physical sciences & engineering, and social & political sciences, so match the rigor conventions of your division:

  • Biological / health / medical: replication unit, ARRIVE-style animal reporting, antibody/reagent validation, clinical-study reporting standards (CONSORT/STROBE) where applicable.
  • Social / political / behavioral: pre-registration is increasingly expected; report power, sampling frame, and deviations from the plan.
  • Physical / engineering / computational: report uncertainties, error propagation, and numerical reproducibility (seeds, solver settings).

Avoid the classic reviewer kills

  • Pseudoreplication: treating technical replicates / cells from one animal as independent n.
  • HARKing / p-hacking: presenting exploratory findings as confirmatory. Label exploratory work as such (or run a Registered Report).
  • "Representative" images with no quantification across replicates.
  • Bar chart + SEM masking a tiny, variable n.
  • Comparing two effects by their significance ("significant here, not there") instead of testing the difference.

Reproducibility package

  • Analysis code in a public repository, archived for a DOI (see pnasnexus-data), with a README and environment/versions.
  • Deterministic where possible; report random seeds for simulations/ML.
  • Because PNAS Nexus mandates that code and data be available in a public repository upon publication, build the reproducibility package as you go — it is not optional here.

Output format

【Per-claim backbone】 effect+CI / n / unit-of-n / test / assumptions → list gaps
【Replication】 biological vs technical clear? yes/no
【Sample-size rationale】 power/justification present? yes/no
【Randomization & blinding】 reported / N/A-justified / missing
【Multiplicity】 corrected? method
【Registered Report?】 confirmatory work → Stage 1/2 considered? yes/no/N-A
【Division-specific rigor】 (Bio-Health-Medical / Physical-Engineering / Social-Political) conventions met? yes/no
【Reproducibility】 code + versions + seeds in a public repo (mandatory)? yes/no
【Next】 pnasnexus-data

Anti-patterns

  • Do not report P without effect size and n.
  • Do not count technical replicates as independent observations.
  • Do not infer "no effect" from a non-significant test on an underpowered sample.
  • Do not present post-hoc subgroup findings as if pre-specified — use a Registered Report for true confirmatory tests.
  • Do not defer the reproducibility package — public data/code is mandatory at PNAS Nexus.
