Update docx, pptx, and xlsx skills (#1447)

Add support for template formats (.dotx, .potx, .xltx) across validation
and the helper scripts.

Consolidate the shared office helpers into a single module, replacing the
pack/unpack pipeline with explicit zip/unzip steps. Extraction now rejects
symlink and path-traversal archive entries. Move run merging to a
standalone docx script, since it only ever applied to Word documents.

Fix the redlining validator so it compares against the original even when
a document has no tracked changes, which is when an untracked edit would
otherwise go unreported.

Provision a LibreOffice user profile per invocation so conversions work in
sandboxed environments.

Trim the skill docs to the guidance that earns its place.

# DOCX creation, editing, and analysis
## Overview
A .docx file is a ZIP archive containing XML files.
## Quick Reference
A `.docx` is a ZIP archive of XML files. Choose your approach by task:
| Task | Approach |
|------|----------|
| Read/analyze content | `pandoc` or unpack for raw XML |
| Create new document | Use `docx-js` - see Creating New Documents below |
| Edit existing document | Unpack → edit XML → repack - see Editing Existing Documents below |
|---|---|
| **Create** a new document | Write a `docx` (npm) script — see gotchas below |
| **Edit** an existing document | `unzip` → edit `word/document.xml``zip` (docx-js cannot open existing files) |
| **Read** content | `pandoc -t markdown file.docx` |
### Converting .doc to .docx
> Script paths below are relative to this skill's directory.
Legacy `.doc` files must be converted before editing:
## Creating with docx-js — gotchas
`docx` is preinstalled — do not run `npm install` first; write the script and `require('docx')` directly. Only if that require fails: `npm install docx`. The model knows the API; these are the footguns:
- **Page size defaults to A4.** For US Letter set `page: { size: { width: 12240, height: 15840 } }` (DXA; 1440 = 1″).
- **Landscape:** pass portrait dimensions and `orientation: PageOrientation.LANDSCAPE` — docx-js swaps width/height internally.
- **Tables need dual widths:** set `columnWidths` on the table AND `width` on every cell, both in `WidthType.DXA` (PERCENTAGE breaks in Google Docs). Column widths must sum to the table width.
- **Table shading:** use `ShadingType.CLEAR`, never `SOLID` (renders black).
- **Lists:** never insert `•` literally; use a `numbering` config with `LevelFormat.BULLET`.
- **`ImageRun` requires `type:`** (`"png"`, `"jpg"`, …).
- **`PageBreak` must be inside a `Paragraph`.**
- **Never use `\n`** — use separate `Paragraph` elements.
- **TOC:** headings must use built-in `HeadingLevel.*`; custom heading styles need `outlineLevel` set or they won't appear.
- **Don't use a table as a horizontal rule** — use a paragraph bottom border instead.
- **Dot-leader / right-aligned-on-same-line:** use `PositionalTab` (`alignment: PositionalTabAlignment.RIGHT`, `leader: PositionalTabLeader.DOT`) inside a `TextRun`, not literal `.` or space padding.
## Verify the output
After writing a `.docx`, render it and look at it:
```bash
python scripts/office/soffice.py --headless --convert-to docx document.doc
python scripts/office/soffice.py --headless --convert-to pdf output.docx
pdftoppm -jpeg -r 100 output.pdf page
ls page-*.jpg # then Read the images
```
### Reading Content
`pdftoppm` zero-pads page numbers to the width of the page count (`page-01.jpg``page-12.jpg`).
## Editing existing documents
Legacy `.doc` files must be converted first: `python scripts/office/soffice.py --headless --convert-to docx file.doc`.
```bash
# Text extraction with tracked changes
pandoc --track-changes=all document.docx -o output.md
# Raw XML access
python scripts/office/unpack.py document.docx unpacked/
unzip -q doc.docx -d unpacked/
find unpacked -type l -delete # strip symlink entries — docx from external parties is untrusted
python scripts/merge_runs.py unpacked/ # coalesce fragmented runs so text is findable
# edit unpacked/word/document.xml in place — do NOT reformat or pretty-print
(cd unpacked && rm -f ../out.docx && zip -Xr ../out.docx .)
python scripts/office/validate.py out.docx --original doc.docx # XSD checks; --auto-repair fixes common issues
# redlining? add --author "<the name you redlined under>" to check every edit is tracked
```
### Converting to Images
Word splits text across many `<w:r>` runs (revision ids, spell-check markers), so a phrase you can see in the document often doesn't exist as a contiguous string in the XML. `merge_runs.py` merges adjacent identically-formatted runs in `word/document.xml` without changing content or rendering; it also accepts a `.docx` directly (`python scripts/merge_runs.py doc.docx -o merged.docx`).
**Tracked changes:** when redlining, validate with `--author "<the name you redlined under>"` (needs `--original`) — it reports any text you changed without a `<w:ins>`/`<w:del>` around it, which is easy to do by accident and invisible in the accepted view. Wrap runs in `<w:ins>`/`<w:del>` with `w:id`, `w:author`, `w:date` attributes. Inside `<w:del>`, the text element is `<w:delText>`, not `<w:t>`. A deleted paragraph mark (`<w:pPr><w:rPr><w:del w:id=".." w:author=".." w:date=".."/></w:rPr></w:pPr>`) means "merge this paragraph into the next" — so deleting a paragraph outright is that plus a `<w:del>` around every run. The `<w:del/>` must come before the rPr's other children; their order is schema-enforced.
To produce a clean copy with all tracked changes accepted: `python scripts/accept_changes.py in.docx out.docx`.
Accepting a deleted paragraph mark should join that paragraph to the one below it, so a paragraph whose runs are *all* deleted vanishes. Word does this; `accept_changes.py` and `pandoc --track-changes=accept` don't always. Both fail the same way — they strip the deleted text but leave the emptied paragraph behind, which reads as a stray empty bullet when it was auto-numbered:
- `pandoc --track-changes=accept` never joins the paragraphs.
- `accept_changes.py` (LibreOffice) joins them correctly, except when the deleted paragraph is followed by an empty spacer paragraph.
An empty bullet in either view is an artifact of that view, not a defect in the document. Check paragraph deletions in the XML.
## Comments
Comments require six cross-linked files. Use the helper — directory mode when you'll also be editing `document.xml` (saves an unzip/rezip cycle), `.docx`-direct mode otherwise:
```bash
python scripts/office/soffice.py --headless --convert-to pdf document.docx
pdftoppm -jpeg -r 150 document.pdf page
# Against an already-unpacked directory (preferred when also placing markers)
python scripts/comment.py unpacked/ "Fees & expenses cap is too low"
python scripts/comment.py unpacked/ "Agreed" --parent 0
# Against a .docx directly
python scripts/comment.py contract.docx "This cap is too low" -o annotated.docx
```
### Accepting Tracked Changes
To produce a clean document with all tracked changes accepted (requires LibreOffice):
```bash
python scripts/accept_changes.py input.docx output.docx
```
---
## Creating New Documents
Generate .docx files with JavaScript, then validate. Install: `npm install -g docx`
### Setup
```javascript
const { Document, Packer, Paragraph, TextRun, Table, TableRow, TableCell, ImageRun,
Header, Footer, AlignmentType, PageOrientation, LevelFormat, ExternalHyperlink,
InternalHyperlink, Bookmark, FootnoteReferenceRun, PositionalTab,
PositionalTabAlignment, PositionalTabRelativeTo, PositionalTabLeader,
TabStopType, TabStopPosition, Column, SectionType,
TableOfContents, HeadingLevel, BorderStyle, WidthType, ShadingType,
VerticalAlign, PageNumber, PageBreak } = require('docx');
const doc = new Document({ sections: [{ children: [/* content */] }] });
Packer.toBuffer(doc).then(buffer => fs.writeFileSync("doc.docx", buffer));
```
### Validation
After creating the file, validate it. If validation fails, unpack, fix the XML, and repack.
```bash
python scripts/office/validate.py doc.docx
```
### Page Size
```javascript
// CRITICAL: docx-js defaults to A4, not US Letter
// Always set page size explicitly for consistent results
sections: [{
properties: {
page: {
size: {
width: 12240, // 8.5 inches in DXA
height: 15840 // 11 inches in DXA
},
margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 } // 1 inch margins
}
},
children: [/* content */]
}]
```
**Common page sizes (DXA units, 1440 DXA = 1 inch):**
| Paper | Width | Height | Content Width (1" margins) |
|-------|-------|--------|---------------------------|
| US Letter | 12,240 | 15,840 | 9,360 |
| A4 (default) | 11,906 | 16,838 | 9,026 |
**Landscape orientation:** docx-js swaps width/height internally, so pass portrait dimensions and let it handle the swap:
```javascript
size: {
width: 12240, // Pass SHORT edge as width
height: 15840, // Pass LONG edge as height
orientation: PageOrientation.LANDSCAPE // docx-js swaps them in the XML
},
// Content width = 15840 - left margin - right margin (uses the long edge)
```
### Styles (Override Built-in Headings)
Use Arial as the default font (universally supported). Keep titles black for readability.
```javascript
const doc = new Document({
styles: {
default: { document: { run: { font: "Arial", size: 24 } } }, // 12pt default
paragraphStyles: [
// IMPORTANT: Use exact IDs to override built-in styles
{ id: "Heading1", name: "Heading 1", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 32, bold: true, font: "Arial" },
paragraph: { spacing: { before: 240, after: 240 }, outlineLevel: 0 } }, // outlineLevel required for TOC
{ id: "Heading2", name: "Heading 2", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 28, bold: true, font: "Arial" },
paragraph: { spacing: { before: 180, after: 180 }, outlineLevel: 1 } },
]
},
sections: [{
children: [
new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Title")] }),
]
}]
});
```
### Lists (NEVER use unicode bullets)
```javascript
// ❌ WRONG - never manually insert bullet characters
new Paragraph({ children: [new TextRun("• Item")] }) // BAD
new Paragraph({ children: [new TextRun("\u2022 Item")] }) // BAD
// ✅ CORRECT - use numbering config with LevelFormat.BULLET
const doc = new Document({
numbering: {
config: [
{ reference: "bullets",
levels: [{ level: 0, format: LevelFormat.BULLET, text: "•", alignment: AlignmentType.LEFT,
style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
{ reference: "numbers",
levels: [{ level: 0, format: LevelFormat.DECIMAL, text: "%1.", alignment: AlignmentType.LEFT,
style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
]
},
sections: [{
children: [
new Paragraph({ numbering: { reference: "bullets", level: 0 },
children: [new TextRun("Bullet item")] }),
new Paragraph({ numbering: { reference: "numbers", level: 0 },
children: [new TextRun("Numbered item")] }),
]
}]
});
// ⚠️ Each reference creates INDEPENDENT numbering
// Same reference = continues (1,2,3 then 4,5,6)
// Different reference = restarts (1,2,3 then 1,2,3)
```
### Tables
**CRITICAL: Tables need dual widths** - set both `columnWidths` on the table AND `width` on each cell. Without both, tables render incorrectly on some platforms.
```javascript
// CRITICAL: Always set table width for consistent rendering
// CRITICAL: Use ShadingType.CLEAR (not SOLID) to prevent black backgrounds
const border = { style: BorderStyle.SINGLE, size: 1, color: "CCCCCC" };
const borders = { top: border, bottom: border, left: border, right: border };
new Table({
width: { size: 9360, type: WidthType.DXA }, // Always use DXA (percentages break in Google Docs)
columnWidths: [4680, 4680], // Must sum to table width (DXA: 1440 = 1 inch)
rows: [
new TableRow({
children: [
new TableCell({
borders,
width: { size: 4680, type: WidthType.DXA }, // Also set on each cell
shading: { fill: "D5E8F0", type: ShadingType.CLEAR }, // CLEAR not SOLID
margins: { top: 80, bottom: 80, left: 120, right: 120 }, // Cell padding (internal, not added to width)
children: [new Paragraph({ children: [new TextRun("Cell")] })]
})
]
})
]
})
```
**Table width calculation:**
Always use `WidthType.DXA``WidthType.PERCENTAGE` breaks in Google Docs.
```javascript
// Table width = sum of columnWidths = content width
// US Letter with 1" margins: 12240 - 2880 = 9360 DXA
width: { size: 9360, type: WidthType.DXA },
columnWidths: [7000, 2360] // Must sum to table width
```
**Width rules:**
- **Always use `WidthType.DXA`** — never `WidthType.PERCENTAGE` (incompatible with Google Docs)
- Table width must equal the sum of `columnWidths`
- Cell `width` must match corresponding `columnWidth`
- Cell `margins` are internal padding - they reduce content area, not add to cell width
- For full-width tables: use content width (page width minus left and right margins)
### Images
```javascript
// CRITICAL: type parameter is REQUIRED
new Paragraph({
children: [new ImageRun({
type: "png", // Required: png, jpg, jpeg, gif, bmp, svg
data: fs.readFileSync("image.png"),
transformation: { width: 200, height: 150 },
altText: { title: "Title", description: "Desc", name: "Name" } // All three required
})]
})
```
### Page Breaks
```javascript
// CRITICAL: PageBreak must be inside a Paragraph
new Paragraph({ children: [new PageBreak()] })
// Or use pageBreakBefore
new Paragraph({ pageBreakBefore: true, children: [new TextRun("New page")] })
```
### Hyperlinks
```javascript
// External link
new Paragraph({
children: [new ExternalHyperlink({
children: [new TextRun({ text: "Click here", style: "Hyperlink" })],
link: "https://example.com",
})]
})
// Internal link (bookmark + reference)
// 1. Create bookmark at destination
new Paragraph({ heading: HeadingLevel.HEADING_1, children: [
new Bookmark({ id: "chapter1", children: [new TextRun("Chapter 1")] }),
]})
// 2. Link to it
new Paragraph({ children: [new InternalHyperlink({
children: [new TextRun({ text: "See Chapter 1", style: "Hyperlink" })],
anchor: "chapter1",
})]})
```
### Footnotes
```javascript
const doc = new Document({
footnotes: {
1: { children: [new Paragraph("Source: Annual Report 2024")] },
2: { children: [new Paragraph("See appendix for methodology")] },
},
sections: [{
children: [new Paragraph({
children: [
new TextRun("Revenue grew 15%"),
new FootnoteReferenceRun(1),
new TextRun(" using adjusted metrics"),
new FootnoteReferenceRun(2),
],
})]
}]
});
```
### Tab Stops
```javascript
// Right-align text on same line (e.g., date opposite a title)
new Paragraph({
children: [
new TextRun("Company Name"),
new TextRun("\tJanuary 2025"),
],
tabStops: [{ type: TabStopType.RIGHT, position: TabStopPosition.MAX }],
})
// Dot leader (e.g., TOC-style)
new Paragraph({
children: [
new TextRun("Introduction"),
new TextRun({ children: [
new PositionalTab({
alignment: PositionalTabAlignment.RIGHT,
relativeTo: PositionalTabRelativeTo.MARGIN,
leader: PositionalTabLeader.DOT,
}),
"3",
]}),
],
})
```
### Multi-Column Layouts
```javascript
// Equal-width columns
sections: [{
properties: {
column: {
count: 2, // number of columns
space: 720, // gap between columns in DXA (720 = 0.5 inch)
equalWidth: true,
separate: true, // vertical line between columns
},
},
children: [/* content flows naturally across columns */]
}]
// Custom-width columns (equalWidth must be false)
sections: [{
properties: {
column: {
equalWidth: false,
children: [
new Column({ width: 5400, space: 720 }),
new Column({ width: 3240 }),
],
},
},
children: [/* content */]
}]
```
Force a column break with a new section using `type: SectionType.NEXT_COLUMN`.
### Table of Contents
```javascript
// CRITICAL: Headings must use HeadingLevel ONLY - no custom styles
new TableOfContents("Table of Contents", { hyperlink: true, headingStyleRange: "1-3" })
```
### Headers/Footers
```javascript
sections: [{
properties: {
page: { margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 } } // 1440 = 1 inch
},
headers: {
default: new Header({ children: [new Paragraph({ children: [new TextRun("Header")] })] })
},
footers: {
default: new Footer({ children: [new Paragraph({
children: [new TextRun("Page "), new TextRun({ children: [PageNumber.CURRENT] })]
})] })
},
children: [/* content */]
}]
```
### Critical Rules for docx-js
- **Set page size explicitly** - docx-js defaults to A4; use US Letter (12240 x 15840 DXA) for US documents
- **Landscape: pass portrait dimensions** - docx-js swaps width/height internally; pass short edge as `width`, long edge as `height`, and set `orientation: PageOrientation.LANDSCAPE`
- **Never use `\n`** - use separate Paragraph elements
- **Never use unicode bullets** - use `LevelFormat.BULLET` with numbering config
- **PageBreak must be in Paragraph** - standalone creates invalid XML
- **ImageRun requires `type`** - always specify png/jpg/etc
- **Always set table `width` with DXA** - never use `WidthType.PERCENTAGE` (breaks in Google Docs)
- **Tables need dual widths** - `columnWidths` array AND cell `width`, both must match
- **Table width = sum of columnWidths** - for DXA, ensure they add up exactly
- **Always add cell margins** - use `margins: { top: 80, bottom: 80, left: 120, right: 120 }` for readable padding
- **Use `ShadingType.CLEAR`** - never SOLID for table shading
- **Never use tables as dividers/rules** - cells have minimum height and render as empty boxes (including in headers/footers); use `border: { bottom: { style: BorderStyle.SINGLE, size: 6, color: "2E75B6", space: 1 } }` on a Paragraph instead. For two-column footers, use tab stops (see Tab Stops section), not tables
- **TOC requires HeadingLevel only** - no custom styles on heading paragraphs
- **Override built-in styles** - use exact IDs: "Heading1", "Heading2", etc.
- **Include `outlineLevel`** - required for TOC (0 for H1, 1 for H2, etc.)
---
## Editing Existing Documents
**Follow all 3 steps in order.**
### Step 1: Unpack
```bash
python scripts/office/unpack.py document.docx unpacked/
```
Extracts XML, pretty-prints, merges adjacent runs, and converts smart quotes to XML entities (`&#x201C;` etc.) so they survive editing. Use `--merge-runs false` to skip run merging.
### Step 2: Edit XML
Edit files in `unpacked/word/`. See XML Reference below for patterns.
**Use "Claude" as the author** for tracked changes and comments, unless the user explicitly requests use of a different name.
**Use the Edit tool directly for string replacement. Do not write Python scripts.** Scripts introduce unnecessary complexity. The Edit tool shows exactly what is being replaced.
**CRITICAL: Use smart quotes for new content.** When adding text with apostrophes or quotes, use XML entities to produce smart quotes:
```xml
<!-- Use these entities for professional typography -->
<w:t>Here&#x2019;s a quote: &#x201C;Hello&#x201D;</w:t>
```
| Entity | Character |
|--------|-----------|
| `&#x2018;` | (left single) |
| `&#x2019;` | (right single / apostrophe) |
| `&#x201C;` | “ (left double) |
| `&#x201D;` | ” (right double) |
**Adding comments:** Use `comment.py` to handle boilerplate across multiple XML files (text must be pre-escaped XML):
```bash
python scripts/comment.py unpacked/ 0 "Comment text with &amp; and &#x2019;"
python scripts/comment.py unpacked/ 1 "Reply text" --parent 0 # reply to comment 0
python scripts/comment.py unpacked/ 0 "Text" --author "Custom Author" # custom author name
```
Then add markers to document.xml (see Comments in XML Reference).
### Step 3: Pack
```bash
python scripts/office/pack.py unpacked/ output.docx --original document.docx
```
Validates with auto-repair, condenses XML, and creates DOCX. Use `--validate false` to skip.
**Auto-repair will fix:**
- `durableId` >= 0x7FFFFFFF (regenerates valid ID)
- Missing `xml:space="preserve"` on `<w:t>` with whitespace
**Auto-repair won't fix:**
- Malformed XML, invalid element nesting, missing relationships, schema violations
### Common Pitfalls
- **Replace entire `<w:r>` elements**: When adding tracked changes, replace the whole `<w:r>...</w:r>` block with `<w:del>...<w:ins>...` as siblings. Don't inject tracked change tags inside a run.
- **Preserve `<w:rPr>` formatting**: Copy the original run's `<w:rPr>` block into your tracked change runs to maintain bold, font size, etc.
---
## XML Reference
### Schema Compliance
- **Element order in `<w:pPr>`**: `<w:pStyle>`, `<w:numPr>`, `<w:spacing>`, `<w:ind>`, `<w:jc>`, `<w:rPr>` last
- **Whitespace**: Add `xml:space="preserve"` to `<w:t>` with leading/trailing spaces
- **RSIDs**: Must be 8-digit hex (e.g., `00AB1234`)
### Tracked Changes
**Insertion:**
```xml
<w:ins w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z">
<w:r><w:t>inserted text</w:t></w:r>
</w:ins>
```
**Deletion:**
```xml
<w:del w:id="2" w:author="Claude" w:date="2025-01-01T00:00:00Z">
<w:r><w:delText>deleted text</w:delText></w:r>
</w:del>
```
**Inside `<w:del>`**: Use `<w:delText>` instead of `<w:t>`, and `<w:delInstrText>` instead of `<w:instrText>`.
**Minimal edits** - only mark what changes:
```xml
<!-- Change "30 days" to "60 days" -->
<w:r><w:t>The term is </w:t></w:r>
<w:del w:id="1" w:author="Claude" w:date="...">
<w:r><w:delText>30</w:delText></w:r>
</w:del>
<w:ins w:id="2" w:author="Claude" w:date="...">
<w:r><w:t>60</w:t></w:r>
</w:ins>
<w:r><w:t> days.</w:t></w:r>
```
**Deleting entire paragraphs/list items** - when removing ALL content from a paragraph, also mark the paragraph mark as deleted so it merges with the next paragraph. Add `<w:del/>` inside `<w:pPr><w:rPr>`:
```xml
<w:p>
<w:pPr>
<w:numPr>...</w:numPr> <!-- list numbering if present -->
<w:rPr>
<w:del w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z"/>
</w:rPr>
</w:pPr>
<w:del w:id="2" w:author="Claude" w:date="2025-01-01T00:00:00Z">
<w:r><w:delText>Entire paragraph content being deleted...</w:delText></w:r>
</w:del>
</w:p>
```
Without the `<w:del/>` in `<w:pPr><w:rPr>`, accepting changes leaves an empty paragraph/list item.
**Rejecting another author's insertion** - nest deletion inside their insertion:
```xml
<w:ins w:author="Jane" w:id="5">
<w:del w:author="Claude" w:id="10">
<w:r><w:delText>their inserted text</w:delText></w:r>
</w:del>
</w:ins>
```
**Restoring another author's deletion** - add insertion after (don't modify their deletion):
```xml
<w:del w:author="Jane" w:id="5">
<w:r><w:delText>deleted text</w:delText></w:r>
</w:del>
<w:ins w:author="Claude" w:id="10">
<w:r><w:t>deleted text</w:t></w:r>
</w:ins>
```
### Comments
After running `comment.py` (see Step 2), add markers to document.xml. For replies, use `--parent` flag and nest markers inside the parent's.
**CRITICAL: `<w:commentRangeStart>` and `<w:commentRangeEnd>` are siblings of `<w:r>`, never inside `<w:r>`.**
```xml
<!-- Comment markers are direct children of w:p, never inside w:r -->
<w:commentRangeStart w:id="0"/>
<w:del w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z">
<w:r><w:delText>deleted</w:delText></w:r>
</w:del>
<w:r><w:t> more text</w:t></w:r>
<w:commentRangeEnd w:id="0"/>
<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="0"/></w:r>
<!-- Comment 0 with reply 1 nested inside -->
<w:commentRangeStart w:id="0"/>
<w:commentRangeStart w:id="1"/>

### Images
1. Add image file to `word/media/`
2. Add relationship to `word/_rels/document.xml.rels`:
```xml
<Relationship Id="rId5" Type=".../image" Target="media/image1.png"/>
```
3. Add content type to `[Content_Types].xml`:
```xml
<Default Extension="png" ContentType="image/png"/>
```
4. Reference in document.xml:
```xml
<w:drawing>
<wp:inline>
<wp:extent cx="914400" cy="914400"/> <!-- EMUs: 914400 = 1 inch -->
<a:graphic>
<a:graphicData uri=".../picture">
<pic:pic>
<pic:blipFill><a:blip r:embed="rId5"/></pic:blipFill>
</pic:pic>
</a:graphicData>
</a:graphic>
</wp:inline>
</w:drawing>
```

The script writes `comments.xml`, `commentsExtended.xml`, `commentsIds.xml`, `commentsExtensible.xml`, the relationships, and the content-type overrides. Comment IDs are auto-assigned. It then prints the `<w:commentRangeStart>`/`<w:commentRangeEnd>`/`<w:commentReference>` snippet to add to `word/document.xml` so the comment anchors to specific text — until you place those markers, the comment exists but is not visible.
