+description: >-
+  Use this skill whenever the user wants to create, read, edit, or manipulate
+  Word documents (.docx files). Triggers include: any mention of "Word doc",
+  "word document", ".docx", or requests to produce professional documents with
+  formatting like tables of contents, headings, page numbers, or letterheads.
+  Also use when extracting or reorganizing content from .docx files, inserting
+  or replacing images in documents, performing find-and-replace in Word files,
+  working with tracked changes or comments, or converting content into a polished
+  Word document. If the user asks for a "report", "memo", "letter", "template",
+  or similar deliverable as a Word or .docx file, use this skill. Do NOT use for
+  PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document
+  generation.

+# DOCX creation, editing, and analysis
+
+## Overview
+
+A .docx file is a ZIP archive containing XML files.
+
+## Quick Reference
+
+| 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 |
+
+### Converting .doc to .docx
+
+Legacy `.doc` files must be converted before editing:
+
+```bash
+python scripts/office/soffice.py --headless --convert-to docx document.doc
+```
+
+### Reading Content
+
+```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/
+```
+
+### Converting to Images
+
+```bash
+python scripts/office/soffice.py --headless --convert-to pdf document.docx
+pdftoppm -jpeg -r 150 document.pdf page
+```
+
+### 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,
+        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")] })
+```
+
+### 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
+- **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"/>
+  <w:r><w:t>text</w:t></w:r>
+  <w:commentRangeEnd w:id="1"/>
+<w:commentRangeEnd w:id="0"/>
+<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="0"/></w:r>
+<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="1"/></w:r>
+```
+
+### 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>
+```
