What it does

Popl Writing Style is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when drafting or revising POPL prose — building the informal-to-formal ramp from a motivating program to definitions to a sharply stated main theorem, keeping notation coherent across 25 pages of text, writing proof sketches that name the hard case, and framing significance as an idea other PL researchers can reuse.

Its SKILL.md is about 960 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 Writing & Content, covering Brand voice and tone. 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

  • Revising POPL prose — building the informal-to-formal ramp from a motivating program to definitions to a sharply stated main theorem
  • Keeping notation coherent across 25 pages of text
  • Writing proof sketches that name the hard case
  • Framing significance as an idea other PL researchers can reuse

Example prompts

Workflow steps

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

  1. Open with a program, not a framework. Page 1 should show concrete code or a
  2. State the contribution as a sharp claim. "We prove type soundness for λ_X
  3. Walk the example through the machinery before generalizing: the reader should

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

Popl Writing Style loads about 959 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 399 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~959

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.

Use when drafting or revising POPL prose — building the informal-to-formal ramp from a motivating program to definitions to a sharply stated main theorem, keeping notation coherent across 25 pages of text, writing proof sketches that name the hard case, and framing significance as an idea other PL researchers can reuse.

POPL Writing Style

A POPL paper convinces twice: informally, that the problem is real and the idea natural; formally, that the theorems are exactly true. The craft is the ramp between the two. The 25-pages-of-text budget (POPL 2027 call, read 2026-07-08) is generous compared with old conference caps — the failure mode is not compression but unmotivated formalism.

The informal-to-formal ramp

  1. Open with a program, not a framework. Page 1 should show concrete code or a concrete derivation that misbehaves — the phenomenon your formalism explains.
  2. State the contribution as a sharp claim. "We prove type soundness for λ_X with feature Y, the first such result without assumption Z" beats any paragraph of positioning.
  3. Walk the example through the machinery before generalizing: the reader should predict each definition because the example demanded it.
  4. Main theorem by the end of the overview section, at least informally: what is proved, under what assumptions, and what is not claimed.
  5. Only then the full calculus — and every rule shown in the body should be a rule the text actually discusses (popl-supplementary takes the rest).

Proof sketches that earn trust

A body sketch is not a shortened proof; it is a risk disclosure. Name the induction measure, name the case that fails naively, and say what saves it:

text
Proof sketch (Thm 4.1). By induction on the typing derivation. The interesting
case is T-Close: the naive IH is too weak because the closure captures a
context extension. We strengthen the statement to quantify over all well-formed
extensions (Lem 4.3); the remaining cases are routine and mechanized (Sound.v).

A reviewer who reads that sketch knows you met the hard case, and the appendix or mechanization confirms it.

Significance, POPL-flavored

  • Frame the payoff as transferable: "the proof method applies to any calculus with property P," "the logic is parametric in the memory model."
  • Do not oversell breadth a theorem does not have; scoping sentences ("we treat the sequential fragment; concurrency is future work") pre-empt the significance reviewer rather than arming them.
  • Avoid empirical-style adjectives ("fast," "practical") unless popl-experiments backs them; at this venue an unsupported "practical" is an invited objection.
  • Related-work sentences state technical deltas, not lists (popl-related-work).

Output format

[Ramp audit] <page where a concrete example appears / where the main claim is first stated>
[Notation risks] <overloads, forward references, ambient assumptions>
[Sketch quality] <per main theorem: hard case named? measure named?>

[Cut list] <formal material in the body that no text discusses>
