This skill has TWO reference files containing the detailed review rules with ✅/❌ judgment examples. You MUST read both files before running any checks. The bullet points below are summaries only — the reference files contain the actual judgment criteria.

Read these files FIRST:
- references/01_latex_workspace_review.md  (for workspace/full mode)
- references/02_paper_proofreading.md      (for content/full mode)

If the reference files are missing, tell the user that the full review instructions are unavailable rather than proceeding with only the summaries in this file.

When To Use

Invoke when the user asks to:

proofread a LaTeX paper
check LaTeX workspace for submission errors
review paper before conference submission
audit LaTeX preamble, references, labels, figures
find grammar/notation/claim issues in a paper

Mode Selection

Ask the user for mode if not specified:

Mode	Scope	When
`workspace`	LaTeX infrastructure audit (C1-C9)	Preamble, packages, macros, refs, labels, figures
`content`	Paper content proofreading (A-I)	Grammar, claims, structure, notation, captions
`full`	Workspace first, then content	Recommended before submission

Required Input

Root .tex file (e.g., main.tex) — mandatory
Compiled PDF (optional, for content mode — enables figure placement + leftover annotation checks)
If mode is unclear, ask.

File Reading Protocol

Before running any checks, silently read the full workspace:

Read the root .tex file
Resolve every \input{...} and \include{...} recursively
Read shared preamble/macro files: shortcuts.tex, macros.tex, commands.tex, preamble.tex
Read shared symbol files: preamble_symbols.tex, preamble_packages.tex (in ../references/ if workspace uses shared folder)
Read every referenced .bib file
Check figures/ directory for missing assets (workspace mode)
Distinguish figures/ (final manuscript figures) from pics/ (raw sources — do NOT flag for missing .tex references)
If PDF is provided, use it for figure placement and leftover annotations (content mode)

Never review only the top-level file unless the user explicitly narrows scope.

Two-Phase Protocol

Phase 1: Detection Only

CRITICAL: Do NOT modify any files in Phase 1. Do NOT rewrite paragraphs. Do NOT apply style changes proactively.

Report all findings with unique IDs: [1], [2], [3]...
For each finding include: severity, location (file + line), diagnosis, why it matters, actionable fix direction
Severity levels: CRITICAL | MAJOR | MINOR | STYLE
If nothing is wrong, say so clearly and mention remaining limits (missing PDF, missing bib files, etc.)

After Phase 1 output, stop and wait for user decision.

Phase 2: Approved Fixes Only

Only edit files after explicit user approval:

Command	Action
`fix safe`	Only definite typos, duplicate words, clear grammar errors
`fix all critical`	Only CRITICAL issues
`fix 1, 3, 5`	Specific issue numbers
`fix all`	All issues
`discard 3, 7`	Skip specific issues

When fixing:

Apply only approved fixes
Keep edits minimal and localized
Preserve meaning, notation, and LaTeX structure
Do NOT silently fix unapproved neighboring issues
After edits, summarize what changed and note anything intentionally left untouched

Editing Constraints

When applying fixes in Phase 2:

No em dashes (—) in rewritten prose — use comma, colon, semicolon, or restructure
Prefer precise, concrete wording over vague intensifiers
Do not change scientific claims unless user explicitly asks
Preserve LaTeX structure, labels, and macros where possible
Avoid introducing new terminology unless required for consistency

Workspace Audit Checklist (C1-C9)

These are summaries. Read references/01_latex_workspace_review.md for full rules with examples.

C1 — Preamble Configuration

Duplicate/conflicting/unused/missing packages. cleveref [nameinlink,capitalize] options. hyperref colorlinks. caption font consistency. Math packages (amsmath, mathtools, bm). Algorithm environment conflicts.

C2 — Package Load Order & Conflicts

hyperref→cleveref. amsmath→mathtools. xcolor→tikz. caption→subcaption. Flag subfig+subcaption conflict, epsfig redundancy, \usepackage{times}/pslatex.

C3 — Macro Safety & Naming Consistency

\methodname defined once, used consistently, no hardcoded strings. \xspace on text-mode macros. \etalcite defined and used with ~ + plural verb. Subscript macros for repeated patterns. Shared symbol conflicts between local and shared preamble files. \renewcommand flagged as intentional or accidental.

C4 — Cross-Reference Consistency

\Cref{} standardization. Multi-reference grouping. Subfigure format 5(a) with \renewcommand\thesubfigure. Forward references minimized. ~ spacing before \Cref{}.

C5 — Label Naming Convention

Prefixes: fig:, tab:, eq:, sec:, alg:, app:. No duplicate labels. No unreferenced labels. No dangling \ref{} calls.

C6 — Citation & Bibliography

Cited keys in bib. Unused bib entries. Duplicate BibTeX keys across files. arXiv formatting. Missing required fields. Venue abbreviation consistency. ~ before \cite{}.

C7 — Figure & Table Safety

Missing figure files. Dummy/placeholder figures. Absolute paths. Label placement (inside \caption{} or before, NOT after). Unreferenced figures/tables. Missing size specs. \hline vs booktabs. Decimal alignment (siunitx S columns).

C8 — Hidden Human Errors

TODO, XXX, FIXME, TBD, ???, [CITE], [REF], [FILL], \tobeupdated. Inconsistent method/dataset/metric naming. Default template content. \journalVersion{} non-empty. deprecated/ folder still \input-ted. Double spaces. Missing ~. Hard-coded \\ in prose. \vspace{-Xmm} accumulated total.

C9 — Academic Writing (LaTeX-Detectable)

Unit formatting (\,). Thousand separators. \ie/\eg macros (define if missing). state-of-the-art noun vs adjective. Acronym first-use in abstract AND body separately. Sentences starting with "And", "But", "Or". "etc." in formal prose. Figure reference order vs document position.

Content Proofreading Checklist (A-I)

These are summaries. Read references/02_paper_proofreading.md for full rules with examples.

A — Language & Grammar

Subject-verb agreement. Articles. Prepositions. Tense consistency (present for facts/contributions, past for experiments). Related Work tense (present preferred; flag only mixing). Oxford comma. Comma splices.

B — Language Quality & Awkward Expression

Typos/spelling → CRITICAL. Duplicate words → CRITICAL. Nominalization (prefer direct verbs). Redundant expressions ("In order to"→"To"). Citation-as-noun (use Author~\etalcite{#}). Circular descriptions. Verb choice ("suggest"→"propose"/"investigate"/"present").

C — Scientific Clarity & Claims

Every "significantly" needs statistical test or quantitative alternative. "outperform"/"superior"/"state-of-the-art" verified across all metrics. Causal logic gaps. Variables used before definition. Claims in figure captions. "Only a few works..." contradicted by citation list. Scope-limiting language without justification.

D — Structure & Flow

Introduction: dedicated contribution paragraph. Related Work: standalone section (CRITICAL if merged into intro), 15-25 papers for 6-8 page paper, at least one comparison to this work (MAJOR if none). Method: equation references with narrative context. Experiments: each opens with WHY/WHAT/HOW statement, claim coverage verified, most impressive first. General: no repetition across sections, no verbatim intro→conclusion copy, ablation cross-references method section.

E — Figure, Table & Caption Review

Captions: grammatically complete, self-contained (abbreviations defined, baselines cited with \cite{}, datasets named), no body text duplication, period at end. Figures: font size consistent with caption (\footnotesize), tick labels legible, thousand separators in axis ticks, no excessive whitespace. Tables: bold/underline convention defined in caption, consistent metric names, units in headers. Reference order: sequential ascending. Quantitative consistency: text numbers match table/figure data exactly → CRITICAL if mismatch.

F — LaTeX Formatting

Thin space before units (\,). Thousand separators for integers ≥1000 (NOT decimals). Consistent figure reference style. \ie/\eg macros. et al. with period. ~ before \cite/\ref. state-of-the-art consistency.

G — Abstract & Conclusion Quality

Abstract: WHY(1-2 sentences)→PROBLEM(1 sentence)→HOW&WHAT(~3 sentences)→RESULTS(1 sentence). Acronyms expanded within abstract. Zero \cite{} → CRITICAL. Single paragraph → CRITICAL if broken. Conclusion: not verbatim abstract restatement. Limitations acknowledged. Future work specific with grounding sentence.

H — Notation Consistency

Symbol overload detection (build symbol table across all equations). Different symbols for same concept. Vector/matrix boldface (\mathbf{}). Greek vectors (\boldsymbol{}). Coordinate frame notation consistent subscript order. Superscript semantic consistency. Term capitalization consistency.

I — Hyphenation Consistency

Rule 1: Compound adjective before noun → hyphenate (real-time system). Rule 2: -ly adverb + adjective → NEVER hyphenate (tightly coupled, NOT tightly-coupled). Common robotics/CV patterns: "end-to-end", "state-of-the-art", "deep learning" (noun phrase, not hyphenated as adjective).
