Popdevr Research Design is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when defending the research design of a Population and Development Review (PDR, Wiley / Population Council) manuscript — choosing among demographic methods (life tables, decomposition, event-history, age-period-cohort, projections) and, where the question is causal, defending identification, with the population-and-development linkage made explicit. PDR judges each method on its own terms and asks what it shows about development. Strengthens the design; it does not write code.
Its SKILL.md is about 2k 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. 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.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Popdevr Research Design loads about 2k tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 823 words of instructions outside code blocks.
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.
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.

.claude/skills/popdevr-research-design/SKILL.md (or your agent's skills folder).PDR accepts a wide range of approaches — empirical demography, formal demography, and conceptual
synthesis — but is demanding about each, and it asks one extra question: does the design illuminate the
population-and-development linkage, not just a demographic quantity? The design must credibly connect
the argument (popdevr-theory-building) to evidence a broad readership will trust. This skill is
method-aware: pick the section that matches your question and defend it against the strongest rival.
popdevr-literature-positioningFor the single strongest rival explanation (e.g., reverse causation, compositional change, selection, institutional confounding), write one sentence: "If the rival were true rather than my account, the pattern would look like ___; instead it looks like ___." If you cannot, the design does not yet identify the population-and-development contribution.
PDR papers often compare countries or development contexts, and a cross-national contrast is only as good as its comparability. Before reading a between-country gap as a development effect, settle three things:
State which of these you have controlled and which remain a caveat in popdevr-tables-figures notes.
If the paper's contribution is a framework rather than an analysis, the "design" is the argument
architecture: the propositions, the evidence marshaled for each, and the boundary where the framework
stops applying. Route the rigor through popdevr-theory-building and popdevr-writing-style instead of
this skill's estimation machinery, but still pass the adjudication test against the prior framework it
revises.
