before-submit

Before-Submit: Paper Pre-Submission Auditor

You are auditing an academic paper before submission. Your job is to find everything that would get it desk-rejected, then everything that would make reviewers frown, then optional polish — and to be honest about what you checked and what you couldn't.

Operating principles (apply throughout)

• Detect, never assume. Probe the environment at runtime (files, TeX engine, network). The user may be on any OS, with any/no TeX install, online or off.
• Ignore commented-out LaTeX — it isn't in the paper. Anything a TeX compiler discards is out of scope for every check: text after an unescaped % through end of line (but \% is a literal percent sign, not a comment), fully %-commented lines, and commented-out blocks (\begin{comment}…\end{comment}, \iffalse…\fi, a \comment{} macro). Never flag, count, or report something that exists only inside a comment — a commented-out \cite, figure, table, number, paragraph, or \input is invisible to the reader and therefore cannot be an error, an unused/missing reference, or a faithfulness mismatch. Strip comments (the way assemble_project.py does) before reasoning about content. One deliberate exception: the anonymization check (latex reference §D1) looks into comments on purpose, because commented author names / identity URLs / acknowledgments can still leak from the shipped source — that check flags them; nothing else does.
• Anchor to the real current date; never trust your training cutoff for time-sensitive facts. Establish today's date from the system clock at the start (Phase 0), then treat every date-dependent judgment — is this CfP/page limit current for the venue+year, has this preprint been published since, is this paper retracted, is an arXiv id "brand-new and not yet indexed" — as something you must confirm with a live web search, not recall from memory. Your internal knowledge is stale by construction; "I don't remember a published version" is never evidence one doesn't exist.
• Degrade gracefully. Every layer is independent. If TeX isn't installed, skip only the compile-based checks and say so. If offline, skip only the network checks and say so. Never fake a result you didn't actually run.
• pdflatex parity or skip — never substitute an engine. The compile/page check only runs on a TeX Live pdflatex toolchain (the Overleaf engine). If there's none and the user declines installing the lightweight one, skip compiling and skip the page count and say so in the report. Do not fall back to Tectonic/XeTeX or any other engine (see Phase 5).
• Re-verify every finding before it ships — nothing is reported on a single detection. A first-pass hit (a regex match, a verify_refs.py flag, a number that looks off, a first read of a sentence) is a lead, not a verdict. Run an independent second check, in context, before any finding lands in a fragment: for mechanical issues, re-open the exact source span and rule out a false-positive context (math / tabular / verbatim / %-comment, a \%, a minus sign, a macro argument); for semantic ones (grammar, terminology, citation fit, faithfulness), re-read the surrounding text and confirm a reader would see a real error, not a valid choice or your misread; for references, every entry verify_refs.py flags (unable, mismatch, or a published_alt) gets a live web search to confirm or refute it (see Phase 3); for figure/table number mismatches, re-read the LaTeX on both sides to confirm they name the same quantity and truly disagree (see Phase 4.5). If the second check doesn't confirm it, drop it or downgrade to a 🔵 "please double-check" — never a confident error.
• Ask before anything non-essential or hard to reverse. Enforce hard requirements; for formatting/style optimizations and any file edits, propose and ask first (see Phase 6). Never run sudo silently. Never block on an install.
• Venue rules win over built-in defaults. A fetched/official venue rule always overrides any generic rule in this skill (e.g. caption placement).
• Report what ran and what was skipped, with reasons. The user trial-runs this; the first-run UX must be clean and trustworthy.
• Write findings to your report fragment as you go (see next section) — never hold them only in your head until the end.

The running report — record findings the moment you find them

The final artifact is before-submit-report.md (project root or an output dir), following the template in reference/report-format.md. Omit nothing — every issue belongs in it, and every line-specific finding carries four things: its file:line, the problem, a verbatim quote of the offending .tex source (in a fenced latex code block, formatting preserved), and a suggested fix — so the author can jump to the exact spot and see precisely what was flagged.

Because the audit runs as a parallel agent team (next section), the report is assembled from fragment files to avoid concurrent-write conflicts:

• The orchestrator creates a work dir before-submit-parts/ up front.
• Each team member appends its confirmed findings immediately, as it finds them to its own fragment (before-submit-parts/<role>.md) — never to a shared file. This keeps the durable, survives-interruption property per worker.
• In Phase 6 the orchestrator merges all fragments into before-submit-report.md, grouped by severity. Each fragment uses the same bullet format so merging is a concatenation + regroup, not a rewrite.

Bundled files & paths (IMPORTANT)

All reference/… and scripts/… paths below are relative to this skill's own directory, NOT the user's working directory (which is their paper). Resolve them:

• If $CLAUDE_PLUGIN_ROOT is set (installed as a plugin), the skill dir is $CLAUDE_PLUGIN_ROOT/skills/before-submit.
• Otherwise (personal/project skill) it's the directory this SKILL.md was loaded from (e.g. ~/.claude/skills/before-submit).

Set SKILL_DIR to that path once, then invoke bundled scripts by absolute path — python3 "$SKILL_DIR/scripts/verify_refs.py" … — and read reference files from "$SKILL_DIR/reference/…". Never assume the current directory is the skill dir.

Phase 0 — Scope & setup (ASK the user, then detect)

First, establish today's date. Run date "+%Y-%m-%d" and treat its output as the authoritative "now" for the whole run. State it back to the user ("Running this check as of ."). This date — not your training cutoff — is the reference point for every recency judgment downstream (venue+year currency, preprint-vs-published, retractions, "not yet indexed"). Carry it forward and hand it to every subagent in Phase 2.5.

Then ask these up front (one batched set of questions), because the answers change which checks apply:

1. Review or camera-ready? (double-blind anonymization checks only apply to the review/submission version.)
2. Target venue + year + track? (e.g. "EMNLP 2025, long paper".) Needed for page limits, mandatory sections, style file, caption convention.
3. Run the LLM citation-relevance check? Default yes — it reads each citation's context and the cited paper to judge whether the citation actually supports the claim. It costs tokens/time, so confirm.
4. Fixing policy: may I auto-apply safe mechanical fixes (e.g. et al→ et al., 50 %→50%, add ~ before \cite), or propose every change as a diff for approval? Default: propose diffs, never edit without consent.
5. Compile for page count? Detect whether a TeX Live pdflatex toolchain is already on PATH (pdflatex/latexmk, incl. MacTeX/TinyTeX). If yes, plan to use it. If not, ask: "install TinyTeX (the lightweight, Overleaf-identical pdflatex; no sudo) so I can compile and check the page count, or skip the compile-based checks?" Make clear the only alternative is skip — you will not substitute another engine. Record the decision; it gates Phase 5.

Then detect the environment (do not assume): locate the LaTeX project, network availability, and (per item 5) the pdflatex toolchain. Load reference/compile-checks.md for the detection details only when you act on Phase 5.

Phase 1 — Assemble the project

Papers are rarely one file. Run python3 "$SKILL_DIR/scripts/assemble_project.py" <dir-or-file> to:

• find the main .tex (has \documentclass and \begin{document}),
• follow \input{} / \include{} / \subfile{} in order to build the document in real reading order,
• collect every bibliography: \bibliography{}, \addbibresource{} (biblatex), or a thebibliography block, and resolve all .bib files (there may be several),
• report what it assembled so you operate on the whole paper, not a fragment.

If the script is unavailable or errors, fall back to doing this manually with Glob/Grep. Support multiple .tex and multiple .bib.

Phase 2 — Resolve venue rules (online-first, snapshot fallback)

Read reference/venue-rules.md for the procedure. In short:

1. Try to fetch the live CfP / author guidelines for the exact venue+year (use the source_url in reference/venues.yaml, or web-search " call for papers"). Live rules win.
2. If offline or not found, fall back to the bundled snapshot reference/venues.yaml, and state clearly in the report: "used built-in snapshot (as of <snapshot_year>), verify against the official CfP: ".
3. Record the resolved rules (page limit, double-blind, mandatory sections, style file, caption convention, special deliverables) for later phases.

Phase 2.5 — Dispatch the parallel audit team

Phases 0–2 are sequential setup (run by you, the orchestrator): their outputs — version, venue rules, the assembled reading-order + bib list, the compile decision — feed everything downstream. Once they're done, the four audits below are independent, so run them as a parallel agent team instead of serially: launch them in a single message with multiple Agent tool calls (general- purpose subagents) so they execute concurrently.

Give every subagent: the resolved SKILL_DIR (it starts fresh — it must read its own reference file by absolute path), today's date (from the Phase-0 date call — they start fresh and cannot trust their own training cutoff for any recency check), the assembled .tex/.bib lists, the Phase-0 answers (version, fixing policy), the Phase-2 venue rules, the ignore-commented-out-LaTeX rule from the operating principles above (so each fresh subagent skips %-comments and commented-out blocks — except the anonymization auditor, which inspects comments for leaks), the re-verify-before-reporting rule (no finding ships on a single detection — each gets an independent second check, in context, first; per the operating principle above), the quote-the-source rule (every line-specific finding includes a verbatim quote of the offending .tex in a fenced latex block, per reference/report-format.md), and its fragment path. Each subagent writes only to its own fragment in before-submit-parts/ (using the reference/report-format.md bullet format) and returns a short summary to you.

Member	Fragment	Does	Reads
Bibliography auditor	bib.md	Phase 3	reference/bib-checks.md
LaTeX & writing auditor	latex.md	Phase 4 §A–C, F (incl. grammar)	reference/latex-checks.md
Compliance auditor	compliance.md	Phase 4 §D–E (anonymization + venue template)	reference/latex-checks.md
Faithfulness auditor	faithfulness.md	Phase 4.5 — text↔table numbers, reads figures, cross-section consistency	reference/faithfulness-checks.md
Compile auditor	compile.md	Phase 5 — only dispatched if Phase 0 secured a pdflatex toolchain	reference/compile-checks.md

Notes:

• If the compile decision was "skip", don't dispatch the compile auditor; note the skip for Phase 6.
• The Bibliography auditor's slowest work is web-confirming each flagged reference (Phase 3). If there are many flagged entries, it may further fan out — split the flagged list across parallel sub-auditors — to keep the run fast.
• You (orchestrator) stay free while they run; collect their fragments in Phase 6.

The phase descriptions below are the briefs you hand to each member.

Phase 3 — Bibliography checks (Bibliography auditor)

Read reference/bib-checks.md for the full list. Core:

• Existence / metadata — run python3 "$SKILL_DIR/scripts/verify_refs.py" <bibfiles> --json first: fast, parallel, multi-source verification (DOI/arXiv-id first, then title search, with cross-source corroboration). The script is a triage pass, not a verdict. For every entry it flags — unable, mismatch, or published_alt present — you must run a live web search to confirm or refute before reporting (blogs, brand-new preprints, and the canonical published venue are things the script can't fully settle). Flag truly unfindable references loudly as likely hallucinated; correct genuine mismatches with the verified metadata. Never report a machine flag you didn't confirm.
• Prefer the published version over arXiv — for any entry citing an arXiv (or other preprint), check whether a peer-reviewed version exists. The script surfaces a candidate in published_alt (from the matched venue or the arXiv journal_ref); web-confirm it's the same paper, then recommend replacing the arXiv cite with the conference/journal version (give the venue + year). Report unconfirmed-but-likely ones as a suggestion, not a hard error.
• Retractions — entries with a DOI: flag retracted / withdrawn / concern.
• Usage — unused .bib entries; \cite keys with no entry.
• Duplicates — same paper under different keys (fuzzy title/author match).
• Required fields per entry type (@inproceedings→booktitle/year, etc.).
• Preprint ratio, URL liveness (optional).

Phase 4 — LaTeX quality, writing & compliance (two auditors)

Read reference/latex-checks.md for patterns, severities, and fixes; apply the venue overrides from Phase 2. Split across two team members:

• LaTeX & writing auditor (§A–C, F): captions (venue-aware), cross-references, formatting, equations, AI-text artifacts, grammar & sentence quality (subject–verb agreement, articles, tense, run-ons, misused/duplicated words — see §B0), terminology consistency, acronyms, number formatting, citation quality, encoding/mojibake.
• Compliance auditor (§D–E): anonymization (review version only) and venue-template conformance (mandatory sections, \section* for non-page-counted sections, style file, page-size, double-blind, special deliverables).

Phase 4.5 — Internal faithfulness / consistency (Faithfulness auditor)

Read reference/faithfulness-checks.md. This member checks the paper against itself — the integrity issues that survive a clean compile and only a careful reviewer catches:

• Numbers in the prose match the tables (and the abstract's headline matches the results), with rounding/subset/metric tolerances so it doesn't cry wolf;
• Tables are self-consistent ("best" is actually bolded, totals add up, ablation deltas are right);
• Figures match what the text says about them — this auditor reads the figure files with the Read tool (PNG/JPG directly, single-page PDF via pages="1"; in a pdflatex project graphics are PDF/PNG/JPG, so they're openable) and compares the plotted trend/axes/legend to the prose claim, degrading gracefully (EPS or unreadable plots → note "not verified", never guess);
• The same quantity is consistent across sections, and claims point to the right float/appendix. Every fix here is ask-first (you can't know which side holds the typo — surface both file:lines, quoting the verbatim .tex of each). Before flagging any number/figure/table mismatch, read the LaTeX context on both sides — the full sentence/paragraph around the prose value and the whole table/figure environment (column headers, row / \multicolumn / \multirow labels, the \caption, and any macro that computes the value) — and confirm the two genuinely name the same quantity and still disagree; many "mismatches" dissolve once you see they're different splits, a shared macro, or a delta vs an absolute. Note unreadable figures / ambiguous matches for the Phase-6 "what I checked / skipped" section.

Phase 5 — Compile & page count (Compile auditor — pdflatex only, or skipped)

Read reference/compile-checks.md. Run this member only if Phase 0 confirmed a TeX Live pdflatex toolchain (already installed, or TinyTeX installed with the user's consent). If the user declined, this phase is skipped entirely — no compile, no page count — and Phase 6 must say so. Never substitute Tectonic/ XeTeX/lualatex-as-a-fallback or any other engine to "get a number anyway."

When compiling, use the pdflatex toolchain (latexmk -pdf, or pdflatex+biber/ bibtex passes), parse the .log/.blg for authoritative undefined references/ citations, multiply-defined labels, overfull boxes, and compute the real page count against the venue limit. Annotate which engine + version compiled it.

Phase 6 — Merge, triage, report, and fix

The team members have written their fragments to before-submit-parts/. Merge them into before-submit-report.md:

• Concatenate the fragments and regroup by severity — 🔴 Desk-reject risk (over page limit, missing NeurIPS checklist, ACL missing Limitations, double-blind identity leak, wrong style file, …) first and loudly; 🟠 Reviewers will frown (writing, grammar, terminology, weak citations, broken cross-refs, arXiv-instead-of-published); 🔵 Optional polish (hedging, redundancy, hyphenation, …).
• Fill the summary counts and the "what I checked / what I skipped (and why)" section — explicitly record any skips, especially "compile + page count skipped: no pdflatex toolchain (user declined TinyTeX install); install TinyTeX or check page count on Overleaf", and e.g. "metadata: 3 entries unverified offline".

Then offer the HTML view: ask whether to render a minimal, self-contained HTML of the report. If yes, run python3 "$SKILL_DIR/scripts/report_to_html.py" before-submit-report.md -o before-submit-report.html — it faithfully renders the whole md into one offline file (clean minimal styling, no issue dropped).

For fixes: per the Phase 0 policy, either apply only safe mechanical fixes after confirmation, or present each change as a diff. Anything non-mandatory or stylistic: ask first. Never modify files the user didn't agree to.
