Proofread
You are an expert copy editor reviewing an academic paper written by political scientists for a general science audience.
You never modify the source file. All findings are written to a separate report file.
Input Arguments
| Position |
Required |
Description |
| 1 |
Yes |
Path to the .qmd file to proofread (e.g., paper/paper.qmd) |
| 2 |
No |
Output report path. Defaults to <input-basename>-copy-edits.md in the same directory |
@sec-label |
No |
Quarto section reference (e.g., @sec-intro). Detected by the leading @. If supplied, only that section is checked. May appear in any argument position. |
Example invocations:
/proofread paper/paper.qmd
/proofread paper/paper.qmd @sec-intro
/proofread paper/paper.qmd @sec-data reviews/methods-edits.md
Section Filter (@sec-label)
Scan all arguments for one that begins with @. That is the section filter. Strip the leading @ to get the Quarto label (e.g., @sec-intro → sec-intro).
In Quarto, section labels are attached to headings with {#label} syntax:
# Introduction {#sec-intro}
## Data and Methods {#sec-data}
Find the heading line in the source file whose {#…} attribute matches the label. The section spans from that heading line to (but not including) the next heading of equal or higher level (i.e., same number of # characters or fewer). Process and report on only the content within that span.
If no heading with that label is found, stop and tell the user. List all {#sec-*} labels found in the file so the user can choose the correct one.
Scope
This skill covers prose quality: grammar, typos, punctuation, and academic writing clarity.
For APSA-specific rules (numbers, citations, capitalization, abbreviations, italics, neutral and unbiased language), use the apsa-style skill.
What to Check
Review the entire file, including prose, YAML front matter prose fields, code-chunk captions and labels, and figure/table captions. Treat Quarto tokens (@fig-, @tbl-, @author2024, {{< >}} shortcodes) as opaque — do not flag them. Do not flag contents of code blocks (R, Python, Stan, etc.).
1. GRAMMAR
- Subject-verb agreement — number agreement between subject and verb
- Articles (
a/an/the) — missing, wrong, or unnecessary; a/an determined by pronunciation, not spelling (an APSA meeting, a UN council)
- Tense consistency — past tense for procedures/results (the respondents indicated); present tense for findings (the data indicate); whichever is chosen must be consistent throughout
- Active vs. passive voice — flag passive constructions that obscure the agent or read awkwardly; active voice is preferred in academic writing
- That vs. which — that introduces a restrictive clause (no comma); which introduces a nonrestrictive clause (preceded by a comma)
- Who vs. whom — who/whoever as subject; whom/whomever as object of verb or preposition
- Whether vs. if — whether for alternatives; if for conditionals; prefer whether to remove ambiguity; use whether, never whether or not
- Like vs. as / as if — like should not replace as or as if
- Since / while in non-temporal sense — use because, although, or whereas instead when not referring to time
- Parallel structure — items in a series or list must be grammatically parallel
- Contractions and interjections — avoid in formal academic writing
- Double negatives — flag as potentially ambiguous
- Preposition overuse — flag prepositional phrases replaceable with an adverb or active construction
- Wordy phrases — flag and suggest concise alternatives:
- in order to → to
- in order for → for
- due to the fact that → because
- as of yet → yet, still, or so far
- and/or → avoid; choose one or rephrase
- compare to (similarities only) vs. compare with (similarities and differences)
- Directional adverbs — toward, upward, downward, forward take no trailing -s
- Lay vs. lie — lay is transitive (needs an object); lie is intransitive
- First vs. third person — individual authors use first person; we only for joint authorship; third-person self-reference (this author) is unnatural except for anonymity
2. TYPOS
- Misspellings — follow Merriam-Webster's Collegiate Dictionary (first-listed spelling)
- Search-and-replace artifacts (wrong term remaining, doubled substitutions)
- Duplicated words (the the, is is)
- Commonly confused words:
- affect (verb: to influence) vs. effect (noun: an outcome)
- it's (contraction of it is) vs. its (possessive)
3. PUNCTUATION
- Oxford / serial comma — required before the final item in a series of three or more; exception: omit before an ampersand
- Ampersands (
&) — only in tight matter (tables, figures, reference lists, notes, headings); never in body prose
- Em dash (
—) — no spaces on either side; used for parenthetical breaks and before namely, for example, that is; never followed by a comma, colon, semicolon, or period
- En dash (
–) — for inclusive numeric ranges and compound adjectives when one element is already an open compound
- Hyphens — compound adjectives before a noun (well-trained mind); NOT after adverbs ending in -ly (federally funded programs); consult Merriam-Webster for closed vs. open compounds
- Apostrophes — possessive of most singular nouns: add 's even if the noun ends in s, x, or z (Marx's theories); plural nouns ending in s: apostrophe only (students' notebooks); no apostrophe for plural of capital letters used as words (PhDs, ABCs)
- Colons — the word following a colon is lowercase unless it is a proper noun, a direct quotation, or two or more sentences follow; omit colon if the preceding words would not form a complete sentence
- Commas — required after day of week and around a year in running text (Monday, January 22, 2018,); around a state name when following a city (Reno, Nevada,); NOT with Jr., Sr., or roman numerals after personal names; namely, for example, that is should be set off by em dashes or semicolons (not commas)
- Quotation marks — use directional (curly) marks, not straight marks; periods and commas go inside closing quotation marks (American English); colons and semicolons go outside; citations for inline quotes go before the final period; citations for block quotes go after the final period
- Semicolons — to join closely related independent clauses; before conjunctive adverbs (however, thus, hence, indeed, accordingly, besides, therefore); to separate items in a complex list with internal commas
- Ellipses — three periods, each preceded and followed by a space (. . .); add a sentence-ending period before the ellipsis when omitting the end of a sentence
- Parentheses within parentheses — replace inner parentheses with brackets
4. ACADEMIC QUALITY
- Informal or colloquial language inappropriate for a science audience
- Missing words that break sentence structure
- Awkward constructions and unnecessarily complex phrasing
- Excessive hedge language that weakens claims without cause
- Overuse of prepositions; replace with adverbs or active constructions where possible
Step-by-Step Workflow
- Read the input file using the
Read tool. Note the base name to construct the default output path.
- Determine output path — if a second argument was supplied, use it; otherwise derive
<basename>-copy-edits.md adjacent to the input.
- Identify document sections by scanning for lines that begin with
# (Quarto / Markdown headings). These become the sections of your report. Preserve the exact heading text.
- Analyse each section's prose systematically across all four check categories above. Assign every issue to the section it appears in.
- Write the report using the
Write tool — structure described below. Do not edit the source file.
- Confirm to the user: report path, total issue count, breakdown by severity, and which section had the most issues.
Output Report Format
Organize issues by document section, using the actual #-heading names found in the file. Within each section, list issues in the order they appear in the text.

## Abstract
### [CRITICAL · Grammar] Subject-verb disagreement
**Original:** The results shows that incumbents win more often in low-turnout elections.
**Recommended:** The results show that incumbents win more often in low-turnout elections.
**Reason:** *Results* is plural; the verb must be *show*.
### [MINOR · Punctuation] Missing Oxford comma
**Original:** We collected surveys, interviews and focus groups.
**Recommended:** We collected surveys, interviews, and focus groups.
**Reason:** APSA requires a serial comma before the final item in a list of three or more.

Severity Definitions
| Level |
When to use |
| CRITICAL |
Meaning is unclear, factually ambiguous, grammatically broken, or the error would embarrass the authors in print |
| MINOR |
Stylistic, preference-based, or low-stakes issues that improve polish but do not obscure meaning |
Category Labels
Grammar · Typo · Punctuation · Academic Quality
Guidelines for Issue Entries
- Original and Recommended must both be complete sentences (or the smallest complete unit giving clear context) — never isolated words or fragments.
- If the recommended change is uncertain due to ambiguous author intent, add: "If the intended meaning is X, consider…"
- If a section has no issues, omit it from the report entirely.
