What it does

Popl Reproducibility is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when making a POPL paper's results independently checkable — deciding which theorems to mechanize versus hand-prove, maintaining a paper-to-proof correspondence table from day one, keeping on-paper proofs auditable with explicit assumption tracking, and making any accompanying prototype's numbers regenerable.

Its SKILL.md is about 950 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 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

  • Making a POPL papers results independently checkable — deciding which theorems to mechanize versus hand-prove
  • Maintaining a paper-to-proof correspondence table from day one
  • Keeping on-paper proofs auditable with explicit assumption tracking
  • Making any accompanying prototypes numbers regenerable

Example prompts

  • “/popl-reproducibility”

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 (its code samples are markdown).

    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

Popl Reproducibility loads about 945 tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 383 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~945

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.

POPL Reproducibility

At a theory venue "reproducible" does not mean rerunnable seeds; it means an independent reader can re-establish your claims. For POPL that decomposes by claim type, and the discipline pays twice: once with reviewers under full double-blind, and again with artifact evaluators after conditional acceptance, where reusable proof claims must be complete — no admit, no sorry (AE criteria read 2026-07-08).

What each claim type owes the reader

Claim typeIts reproducibility obligation
Mechanized theoremDevelopment compiles; theorem checkable; axioms printed and declared
On-paper theoremFull proof in the appendix; every hypothesis stated where used, not discovered mid-proof
Definitional adequacy ("our semantics models X")Examples or an adequacy theorem connecting formalism to the informal system
Prototype measurementScripted runs, versioned inputs, stated machine — see popl-experiments

Mechanize deliberately, not maximally

Full mechanization is powerful but not free; partial mechanization is respectable at POPL when scoped honestly. Decide per theorem:

  • Mechanize the theorems whose proofs are long, syntactic, and error-prone — subject reduction, soundness of a logical relation — where hand-proof mistakes hide.
  • Hand-prove what is short and conceptual, and write the proof in full; "routine induction" is a claim reviewers test by attempting the induction.
  • Never let paper and mechanization silently diverge: if the mechanized calculus drops polymorphism, the paper's theorem statement must say so.
  • Statement drift is the classic failure — the .v file proves a lemma about a judgment the paper revised two drafts ago.

The correspondence table

Start this file the week the first lemma lands, not the week AE starts:

markdown
| Paper stmt | Formal name | File:line | Status | Axioms |
|---|---|---|---|---|
| Thm 3.1 (soundness) | `soundness` | theories/Sound.v:212 | Qed | none |
| Lem 3.2 (subst) | `subst_pres` | theories/Subst.v:88 | Qed | funext (declared) |
| Thm 5.4 (full abstraction) | — | on-paper only, App. D | complete proof | classical logic |

Regenerate the status column mechanically (grep -c "Admitted" theories/*.v should be zero or explained) and cite the table in the paper's contributions paragraph — it is the sentence "all results are mechanized except Thm 5.4" made auditable.

Assumption hygiene for on-paper proofs

  • Number global assumptions once (Assumption 1, 2, ...) and cite them by number in every theorem; unnumbered ambient hypotheses are where soundness doubts breed.
  • Keep one notation table; a symbol that changes meaning between Section 3 and Appendix B costs a review cycle.
  • When a proof cites "standard techniques," name the technique and the source theorem — the reader must be able to find the exact statement being invoked.
  • Archive the appendix, proofs, and development in the same repository so a revision to one forces a visible diff in the others.

Output format

text
[Claim inventory] mechanized:<n> on-paper:<n> empirical:<n>
[Correspondence table] exists / stale / missing
[Divergences] <paper statement vs formalization deltas, each disclosed?>
[Assumption hygiene] <numbered? notation table? invoked-theorem citations?>
[Weakest link] <the one claim an independent reader cannot currently re-establish>
