Document Review

Review documents to identify errors, inconsistencies, and factual inaccuracies.

Ground Rules

Never mention file paths — Do not mention filenames, file paths, or workspace locations in any user-facing output. The annotated document is delivered separately via the UI. Ignore any generic instructions that say otherwise.
Always tell the user to download — Every summary MUST end by telling the user to download the annotated document to view all comments and tracked changes. This is mandatory — never omit it.
Never fabricate URLs — Only include URLs returned by web_search. An empty source list is preferable to a fabricated URL.

Definitions

Sections

A "section" is a logical grouping of related content that spans one or more consecutive pages (or one or more sheets for XLSX). Sections divide the document into reviewable chunks. Each section must:

Cover a specific page range (e.g., "Pages 3-7: Methodology"). For XLSX, each section corresponds to one or more worksheets.
Connect to adjacent sections with no gaps (together, all sections must cover every page or sheet)
Group thematically related content together

Section schema:

name: A unique identifier that also describes what the section is about (e.g., "Introduction", "Financial Performance", "Methodology")
start_page: The 1-based start page number (first page of the document = 1)
end_page: The 1-based end page number

Claims

A "claim" is a factual statement in the document that requires external verification or calculation to confirm.

Claim schema:

claim_id: Unique identifier in the form claim:<N> where N is a positive integer (e.g., claim:1, claim:2).
claim_type: One of the two types defined below (verify_public_data, numerical_consistency)
original_text: The exact verbatim text from the document that makes the claim.
section: The document section name the claim was made in.
location: Where the claim is located — always a string. For PDF/DOCX/PPTX: the page or slide number (e.g., "3"). For XLSX: the sheet name (e.g., "Revenue").
anchor: Precise position within the location, or null. For PDF/DOCX/PPTX: a descriptive label (e.g., "paragraph 5", "Risk Factors heading", "Table 2, row 3"). For XLSX: a cell reference (e.g., "B14"). Be specific — use "paragraph 5" not "5".
claim_status: One of the four statuses defined below (unverified, verified, refuted, inconclusive)
source_urls: List of URLs from web_search results that were used to verify or refute this claim. Empty list for numerical_consistency claims and when no sources were found. Never fabricate URLs — only use URLs returned by web_search.

Claim Types

verify_public_data: Facts that need external sources to verify. Requires web search to fact-check.
- Statistics ("U.S. population is 340 million")
- Historical facts ("The Paris Agreement was signed in 2016")
- Published data ("The study had 10,000 participants")
- Attributed claims ("According to WHO, global life expectancy is 73 years")
numerical_consistency: Calculations using numbers from within the document. Requires Python code to perform calculations to verify.
- Addition/subtraction ("Region A: 500 + Region B: 300 = 800 total")
- Percentages ("40% of 1,000 respondents = 400")
- Ratios ("$2.4M budget / 12 months = $200K per month")
- Growth calculations ("from 100 to 125 = 25% growth")

Claim Statuses

unverified: Initial status — the claim has not been fact-checked yet.
verified: Fact-checked and determined to be correct.
refuted: Fact-checked and determined to be false. Refuted claims become issues.
inconclusive: Fact-checked, but no conclusion can be made. Inconclusive claims become issues.

Issues

An "issue" is a specific problem found in the document. Issues are the primary output of the review — every issue becomes a comment/annotation in the final document.

Issue schema:

issue_type: One of the five types defined below (spelling_grammar, narrative_logic, non_public_info, verify_public_data, numerical_consistency)
severity: high, medium, or low (see Severity Levels below)
original_text: The exact verbatim text from the document that contains the issue. This is the text you would highlight to show a reader where the problem is.
description: A concise explanation of why original_text is wrong or problematic. Write as 1-2 direct sentences that a reviewer can scan without re-reading. Lead with what's wrong, then state what's correct or expected. Avoid filler ("It appears that...", "There seems to be...") — state the problem directly. Examples: "Revenue is stated as $28T but publicly reported figures show $25.5T for 2023." / "The word 'acheived' is misspelled." / "Page 3 says 'founded in 2015' but page 7 says 'celebrating 10 years' in 2023, which implies 2013."
text_context: A longer passage containing original_text with surrounding text before and after. Used to disambiguate when original_text appears multiple times in the document.
new_text: The suggested replacement for original_text. Should closely resemble the original but with the issue fixed.
section: The document section name the issue is in.
location: Where the issue is located — always a string. For PDF/DOCX/PPTX: the page or slide number (e.g., "3"). For XLSX: the sheet name (e.g., "Revenue").
anchor: Precise position within the location, or null. For PDF/DOCX/PPTX: a descriptive label (e.g., "paragraph 5", "Risk Factors heading", "Table 2, row 3"). For XLSX: a cell reference (e.g., "B14"). Be specific — use "paragraph 5" not "5".
issue_id: Unique identifier in the form issue:<N> where N is a positive integer (e.g., issue:1, issue:2).
root_issue_id: The issue_id of an earlier issue that caused this one. Use when an error cascades — e.g., page 1 says "U.S. population is 200 million" (wrong, issue:1), then page 2 says "10% of the U.S. population is 20 million" — the math is correct for the stated figure but based on the wrong number from issue:1, so issue:2 sets root_issue_id to issue:1. Omit when the issue is independent.

Issue Types

spelling_grammar: Misspelled words and grammatical errors.
- IS: "acheived" → "achieved" (misspelling)
- IS: "A total of $100 millions dollars" (grammar: "millions" → "million")
- IS: "the the report" (repeated word)
- IS: "Their going to expand" ("Their" → "They're")
- NOT: Wrong dates, wrong numbers, backwards timelines (→ narrative_logic)
- NOT: Redundant or nonsensical titles/headings (→ narrative_logic)
- NOT: Real names used instead of code names (→ non_public_info)
- Test: Could a spell-checker or grammar-checker catch this? If yes → spelling_grammar. If it requires understanding meaning or context → it's another type.
narrative_logic: Logical errors, contradictions, timeline problems, nonsensical content, or structural issues that require understanding meaning to detect.
- IS: "Founded in 2015" on page 3 but "celebrating 10 years" in 2023 (contradiction)
- IS: "Expected to grow from 500 in 2025 to 600 in 2020" (backwards timeline)
- IS: "Comparable Comps Analysis" (tautological — "Comparable" and "Comps" mean the same thing)
- IS: "Fitness Industry Page" as a section title ("Page" is redundant — the audience already knows it's a page)
- IS: Document dated January but references "Q4 results" as if complete (impossible timeline)
- IS: A section header that contradicts the document's own conventions or makes no sense
- NOT: Misspelled words (→ spelling_grammar)
- NOT: Confidential information leaks (→ non_public_info)
- Test: Does this require understanding what the words mean (dates, logic, context) to spot the error? If yes → narrative_logic.
non_public_info: Confidential information that should not appear in the document.
- IS: Using real company names instead of code names (e.g., "Planet Fitness" when code name is "Pluto")
- IS: Individual salaries, SSNs, private email addresses, phone numbers
- IS: Unreleased product details, internal strategies, board deliberations
- IS: "STRICTLY CONFIDENTIAL" or "INTERNAL USE ONLY" markers left in a public-facing document
- NOT: Misspelled names (→ spelling_grammar)
- NOT: Contradictions about confidential info (→ narrative_logic)
- Test: Is the problem that confidential or private information is exposed? If yes → non_public_info.
verify_public_data: Facts that differ from verifiable external sources. Requires web search to verify.
- IS: "U.S. GDP was $28T" but actual is $25T (refuted → create issue)
- IS: "The treaty was signed in 2018" (actually 2016) (refuted → create issue)
- IS: "2024 Q4 results were $45M" but no public data available yet (inconclusive → create issue)
- NOT: Dates that contradict other dates within the document (→ narrative_logic)
numerical_consistency: Math errors using the document's own numbers. Requires calculation to verify.
- IS: "Region A: 500 + Region B: 300 = 900" (should be 800) (refuted → create issue)
- IS: "40% of 1,000 = 500" (should be 400) (refuted → create issue)
- IS: "$2.4M budget / 12 months = $150K/month" (should be $200K/month) (refuted → create issue)
- NOT: A timeline going backwards (→ narrative_logic)

Severity Levels

high: Consequences beyond the document — could lead to wrong decisions, legal exposure, or real-world harm (e.g., materially wrong financials, leaked PII, verifiably false facts with regulatory implications)
medium: Undermines the document's credibility — a reader who notices would question whether the rest of the document can be trusted (e.g., internal contradictions, calculation errors, timeline inconsistencies)
low: Undermines professionalism only — looks sloppy but doesn't mislead or cause harm (e.g., typos, grammar errors, repeated words)

Background Session Setup

Document review is a long, meticulous process — always run it in a background session using the Beeuni sessions flow.

Before spawning, determine which issue types are relevant from the user's request. When in doubt, default to all 5 types. Examples:

"review this", "audit this" → all 5 types
"spell-check this", "proofread this", "check for typos" → spelling_grammar
"fact-check this", "verify the numbers" → verify_public_data, numerical_consistency
"check for confidential info" → non_public_info

text

session_start_background(
  project="<project-name-if-applicable>",
  prompt="Load the document-review skill and execute its workflow to review the attached document. Issue types: [list the relevant issue types]."
)

Use session_read to inspect progress and the final review output. After the background session completes, present the annotated document with show.

When responding to the user after the review completes, do not mention internal file paths or workspace locations. The annotated document should be delivered separately via the UI.

Document Type and Specializations

Before starting the workflow, read the document and determine its type (e.g., "investment memo", "research paper", "marketing proposal", "legal contract"). The document type drives whether to load a specialization file with domain-specific guidance.

If the document matches a specialization below, load it for domain-specific examples, severity calibration, and search strategies. Apply the specialization's guidance throughout all remaining phases.

Finance/Investment (investment memo, CIM, pitch deck, offering memorandum, financial model, quarterly/annual report, prospectus): read("skills/document-review/specializations/finance.md")

For documents that don't match any specialization, do not load a specialization file. Proceed with the general examples and guidance in this file.

Workflow

The review workflow is a 6-phase pipeline that transforms a raw document into an annotated copy with issues marked as comments. Each phase builds on the previous: sections structure the document, claims extract verifiable facts, fact-checking confirms or refutes claims, issues capture all problems found, annotation marks them in the document, and submission finalizes the review. All state is managed through manage_state.py script commands that read and write document_review_state.json.

Execute phases strictly in order — do not reorder. Skip phases only when their conditions below allow it:

Create sections — Analyze document structure and divide into thematic sections
- End: All sections created with page ranges
Create claims — Identify fact-checkable statements and create claim records
- Skip if only spelling_grammar, narrative_logic, and/or non_public_info requested
- End: Claims created from every section
Update claims — Fact-check claims and update their status
- Skip if Phase 2 was skipped or no claims were created
- End: All claims updated (verified/refuted/inconclusive)
Create issues — Review sections for problems and create issue records
- Only create issues for the requested types
- End: Every section reviewed, issues created (including for refuted/inconclusive claims)
Annotate document — Create annotated copy with issues marked as comments/annotations
- End: Annotated document saved to workspace
Submit review — Compile and submit final review
- End: Review submitted

FORBIDDEN: web_search, bash, and connector tools are only for Phase 3 (fact-checking claims). Do not use them in any other phase.

Processing Strategy

All review state lives in document_review_state.json — a single JSON file in the working directory that tracks the current phase, sections, claims, issues, and summary. Every phase reads and writes this file through manage_state.py (at skills/document-review/scripts/manage_state.py). All manage_state.py commands and annotation scripts are executed as bash tool calls. The state file must be initialized with manage_state.py init before any other commands. Use manage_state.py status at any point after initialization to check progress.

Commands that take --data also accept --file as an alternative — the file must contain the same JSON array that would be passed inline to --data. Use --file when the JSON payload is large:

manage_state.py add-issues "Section Name" --file issues.json

Phase 1 (Create sections)

Read the entire document and divide it into thematic sections. Sections define the units of work for all later phases — claims are extracted per section, issues are created per section, so getting the boundaries right here determines the quality of everything downstream.

manage_state.py add-sections --data '[{"name": "Introduction", "start_page": 1, "end_page": 5}, ...]'

Read the document end-to-end before creating sections. Look for natural thematic boundaries: topic shifts, headings, or transitions between distinct subject areas. Name each section descriptively (e.g., "Market Analysis", "Risk Factors", not "Section 3" or "Pages 5-8"). For XLSX, each section typically corresponds to one worksheet — use the sheet name as the section name. Call add-sections once with all sections — together they must cover every page or sheet with no gaps or overlaps.

Section limits:

1–4 pages (or sheets): max 2 sections
5–8 pages (or sheets): max 4 sections
9+ pages (or sheets): max 8 sections

Phase 2 (Create claims)

Scan every section for statements that need external verification or calculation, and create a claim record for each one. Claims feed Phase 3's fact-checking pipeline — they exist only for facts that cannot be confirmed by reading the document alone.

manage_state.py add-claims "Section Name" --data '[{"claim_type": "verify_public_data", "description": "Population was 340 million", "original_text": "Population was 340 million", "location": "5", "anchor": "paragraph 3"}, ...]'

Create a claim when the statement requires:

Web search (verify_public_data) — statistics, dates, published data, or attributed facts that must be checked against external sources
Calculation (numerical_consistency) — arithmetic using numbers from the document (sums, percentages, ratios, growth rates) that must be computed to verify

Do NOT create a claim when the problem is detectable by reading the document:

Timeline impossibilities, internal contradictions, or logical errors (catch as narrative_logic issues in Phase 4)
Spelling errors, typos, grammar mistakes, formatting problems (catch as spelling_grammar issues in Phase 4)
Statements that don't need verification (headers, generic text, opinions)

Process every section. One add-claims call per section. These calls are independent — run up to 4 in parallel.

Phase 3 (Update claims)

Fact-check each claim using the web_search and bash tools, then record results by updating claim statuses through manage_state.py update-claims. Use manage_state.py get-claims --status unverified to check which claims still need fact-checking.

web_search tool — Fact-check verify_public_data claims against external sources. Takes a queries array (max 3 per call): the first query is the primary search, the remaining are reformulations to broaden coverage. Use short, keyword-focused queries — longer queries reduce result quality.

Start broad — a single search can verify multiple related claims (e.g., searching for a company's annual report may confirm revenue, headcount, and founding date at once). Narrow queries to target specific claims only after broad searches leave gaps.
Year selection: Always include the year in queries (e.g., "U.S. GDP 2023" not just "U.S. GDP"). Check the document date first (headers, footers, "as of" statements) and search for data from the year the document references. If unclear, use the most recent complete year before today's date. Don't mix years.
Use allowed_domains to target authoritative sources when relevant (e.g., ["sec.gov", "investor.apple.com"])
Break multi-entity questions into separate single-entity queries
Be pragmatic: if a claim cannot be verified after 2-3 search attempts with different query formulations, mark it as inconclusive and move on. Do not spend unlimited turns chasing a single claim.

bash tool — Verify numerical_consistency claims with Python calculations. Takes a command string — use python3 -c one-liners with exact values from the document. NEVER do mental math — always use bash with Python for numerical verification.

Examples:
- python3 -c "print(500 + 300)" → verify "500 + 300 = 800"
- python3 -c "print(0.40 * 1000)" → verify "40% of 1,000 = 400"
- python3 -c "print(2.4 / 12)" → verify "$2.4M / 12 months = $200K"
- python3 -c "print((125 - 100) / 100 * 100)" → verify "25% growth from 100 to 125"

Parallelism — Fact-checking is the most time-consuming phase. web_search and bash (Python calculations) are independent and can run in parallel (up to 4 per turn).

update-claims — After each round of tool calls, record results for all claims checked in that round:

manage_state.py update-claims --data '[{"claim_id": "claim:1", "claim_status": "verified", "source_urls": ["https://example.com/report"]}, ...]'
Verified — Confirmed accurate. Exact values must match exactly; approximations (~, approximately, about) allow 5% variance.
Refuted — Contradicted by search results or calculations. If you find clear data that contradicts the claim, mark as refuted, not inconclusive.
Inconclusive — Cannot be verified. Mark as inconclusive only when no reliable data exists after multiple search attempts, results genuinely conflict, or data is not yet available (e.g., future periods).
source_urls — Include URLs from web_search results that informed the verdict. For numerical_consistency claims (verified via calculation), pass an empty list. Never fabricate URLs.

text

Turn 4: web_search("Beeuni Corp 2023 annual report") + web_search("U.S. census 2023") + bash(calc claim:5) + bash(calc claim:6)
         → broad searches verify claims 1-3 (revenue, headcount, founding date) + claim 4 (population) + claims 5-6 (math)
Turn 5: update-claims [1-6] + web_search("Beeuni Corp acquisition history") + bash(calc claim:9)
         → narrow search for claims 7-8 that broad searches missed
Turn 6: update-claims [7-9] + web_search("specific fact still unverified")

Phase 4 (Create issues)

Re-read each section and identify every problem — spelling errors, logical contradictions, confidential information leaks, and any issues from refuted or inconclusive claims. This is a fresh pass through the document, not just a conversion of claims to issues. Only create issues for the requested types (see Subagent Setup).

manage_state.py add-issues "Section Name" --data '[{"issue_type": "spelling_grammar", "severity": "low", "description": "Typo found", "location": "3", "anchor": "paragraph 2", "original_text": "acheived", "text_context": "The organization acheived its goals", "new_text": "achieved", "root_issue_id": null}, ...]'

One section per call, sequential in document order. Categorize each issue by its actual nature (see Issue Types in Definitions) — never force an issue into a type just because the user's request mentioned that type.

MANDATORY: Create issues for ALL refuted and inconclusive claims (100% conversion rate). Use manage_state.py get-claims --status refuted and --status inconclusive to ensure none are missed. Preserve the claim's type (verify_public_data → verify_public_data issue, numerical_consistency → numerical_consistency issue). For inconclusive claims, explain why verification failed (e.g., "Data not publicly available", "Conflicting sources found").
Use manage_state.py get-issues to review previously created issues when setting root_issue_id — link cascading errors back to the root issue that caused them.
Never reference claim IDs in issue descriptions — claims are internal tracking; issues become user-facing comments.

Phase 5 (Annotate document)

Create an annotated copy of the document with issues as comments. {base_name} is the original filename without its extension.

PDF/PPTX/XLSX — Single command; the script reads issues from document_review_state.json automatically:
- python3 skills/document-review/scripts/annotate_pdf.py input.pdf {base_name}_reviewed.pdf
- python3 skills/document-review/scripts/annotate_pptx.py input.pptx {base_name}_reviewed.pptx
- python3 skills/document-review/scripts/annotate_xlsx.py input.xlsx {base_name}_reviewed.xlsx
DOCX — read `` and follow its workflow to unpack, edit XML, and repack. Use manage_state.py get-issues to list all issues, then for each issue:
1. Add a comment using comment.py --author "Beeuni", then insert <w:commentRangeStart>, <w:commentRangeEnd>, and <w:commentReference> markers in document.xml. Place <w:commentRangeStart> immediately before the first <w:r> that contains the original_text, and <w:commentRangeEnd> immediately after the last <w:r> that contains it — do NOT place these at the paragraph or body level.
  
  Comment text format — every comment MUST use this exact single-line format. Do NOT use \n or line breaks — comment.py renders them as literal text, not actual breaks. No "Suggested" line — the tracked change shows the fix.
  [Type Label | severity] description
  Type label mapping: spelling_grammar → Spelling/Grammar, narrative_logic → Narrative/Logic, non_public_info → Non-Public Info, verify_public_data → Public Data, numerical_consistency → Numerical Consistency.
  
  Example comment.py call for a spelling issue:
  bash
```
python3 skills/docx/scripts/comment.py unpacked/ 0 "[Spelling/Grammar | low] The word 'acheived' is misspelled." --author "Beeuni"
```
  Example for a numerical consistency issue:
  bash
```
python3 skills/docx/scripts/comment.py unpacked/ 1 "[Numerical Consistency | high] Region totals sum to 800, not the stated 900." --author "Beeuni"
```
2. Apply tracked changes (best effort) when new_text differs from original_text: find the exact <w:r> in document.xml whose <w:t> contains original_text and replace that <w:r> with a <w:del> + <w:ins> pair. Copy the <w:rPr> from that specific <w:r> into both the <w:del> and <w:ins> runs — do NOT use <w:rPr> from any other run (e.g., the title or a different paragraph). Wrap the comment markers tightly around the <w:del> and <w:ins> so the comment is anchored to the change.
Before writing tracked changes, capture the current timestamp in the user's local timezone (from the User Timezone field in the context block): TZ="{user_timezone}" date +"%Y-%m-%dT%H:%M:%SZ" Use this value for all w:date attributes in <w:del> and <w:ins> elements.

The combined pattern for a comment with a tracked change:
xml
```
<w:commentRangeStart w:id="0"/>
<w:del w:id="1" w:author="Beeuni" w:date="{timestamp}">
  <w:r><w:rPr></w:rPr><w:delText>original text</w:delText></w:r>
</w:del>
<w:ins w:id="2" w:author="Beeuni" w:date="{timestamp}">
  <w:r><w:rPr></w:rPr><w:t>new text</w:t></w:r>
</w:ins>
<w:commentRangeEnd w:id="0"/>
<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="0"/></w:r>
```
If the original_text cannot be located in the XML (e.g., it spans multiple runs or paragraphs in a way that makes surgical replacement impractical), still add the comment anchored to the nearest matching text — a comment without a tracked change is better than no annotation at all.

Save the result as {base_name}_reviewed.docx.

Phase 6 (Submit review)

manage_state.py submit "summary text"
Call once after annotation is complete. The summary is the background review session's final output — it becomes the response the user sees.
Use manage_state.py get-issues and get-claims to gather data for the summary.

Summary format:

Opening line — confirm review completion, coverage, and total issue count
Claims summary (skip if no claims were created):
- Total claims checked, broken down by status (e.g., "Verified 42 of 49 claims — 5 refuted, 2 inconclusive")
Issues tables — one table per severity level, each with a heading (e.g., High-Severity Issues):

High-Severity Issues

Location	Type	Issue	Finding
p. 3	Public Data	Revenue stated as $28T	Publicly reported figure is $25.5T for 2023
p. 7	Numerical	Region totals sum to 900	Correct sum is 800 (500 + 300)

Medium-Severity Issues

Location	Type	Issue	Finding
p. 3	Narrative/Logic	Backwards projection year	"to $55-60B by 2020" — 2020 is in the past

Low-Severity Issues

Location	Type	Issue	Finding
p. 5	Spelling/Grammar	"Comparable Comps"	Tautological — "Comps" already means "Comparables"

Closing line — MUST end with a sentence telling the user to download the annotated document to view all comments and tracked changes.

Tone: Professional, constructive, and solution-focused. Frame issues as opportunities for improvement rather than failures.

Example Workflow

For a document with 8 sections and 49 claims:

text

Setup:
  manage_state.py init "Report.pdf"
  (if applicable) read specialization file for domain-specific guidance

Phase 1: Create sections
  Step 1: manage_state.py add-sections --data '[...]' → 8 sections

Phase 2: Create claims
  Step 2: add-claims "Section 1" + add-claims "Section 2" + add-claims "Section 3" + add-claims "Section 4" (4 parallel)
  Step 3: add-claims "Section 5" + add-claims "Section 6" + add-claims "Section 7" + add-claims "Section 8" (4 parallel)
  → 49 claims created

Phase 3: Update claims
  Step 4: get-claims --status unverified + web_search for facts + bash for calculations (parallel)
  Step 5: update-claims [1-15] + web_search(claims 16-30) (parallel)
  Step 6: update-claims [16-30] + bash(calculations 31-45) (parallel)
  Step 7: update-claims [31-45] + final searches (parallel)
  Step 8: update-claims [46-49]
  → All 49 claims updated

Phase 4: Create issues
  Steps 9-16: manage_state.py add-issues "Section N" --data '[...]' (sequential, one per step)
  → Issues created for all problems

Phase 5: Annotate document
  Step 17: python3 skills/document-review/scripts/annotate_pdf.py Report.pdf Report_reviewed.pdf
  → Annotated document saved to workspace

Phase 6: Submit review
  Step 18: manage_state.py submit "Review summary"

Output

The only output file is the annotated document ({base_name}_reviewed{suffix}). Do NOT create separate report files (markdown, text, etc.).
