+## ⚠️ Security Disclaimer
+
+> **Skills can execute code and influence your coding agent's behavior. Review what you install.**
+
+Agent Skills are powerful — they can instruct your AI agent to run arbitrary code, install packages, make network requests, and modify files on your system. A malicious or poorly written skill has the potential to steer your coding agent into harmful behavior.
+
+We take security seriously. All contributions go through a review process, and we run LLM-based security scans (via [Cisco AI Defense Skill Scanner](https://github.com/cisco-ai-defense/skill-scanner)) on every skill in this repository. However, as a small team with a growing number of community contributions, we cannot guarantee that every skill has been exhaustively reviewed for all possible risks.
+
+**It is ultimately your responsibility to review the skills you install and decide which ones to trust.**
+
+We recommend the following:
+
+- **Do not install everything at once.** Only install the skills you actually need for your work. While installing the full collection was reasonable when K-Dense created and maintained every skill, the repository now includes many community contributions that we may not have reviewed as thoroughly.
+- **Read the `SKILL.md` before installing.** Each skill's documentation describes what it does, what packages it uses, and what external services it connects to. If something looks suspicious, don't install it.
+- **Check the contribution history.** Skills authored by K-Dense (`K-Dense-AI`) have been through our internal review process. Community-contributed skills have been reviewed to the best of our ability, but with limited resources.
+- **Run the security scanner yourself.** Before installing third-party skills, scan them locally:
+  ```bash
+  uv pip install cisco-ai-skill-scanner
+  skill-scanner scan /path/to/skill --use-behavioral
+  ```
+- **Report anything suspicious.** If you find a skill that looks malicious or behaves unexpectedly, please [open an issue](https://github.com/K-Dense-AI/claude-scientific-skills/issues) immediately so we can investigate.

+## Query Syntax
+
+The arXiv API uses prefix-based field searches combined with Boolean operators.
+
+**Field prefixes:**
+- `ti:` - Title
+- `au:` - Author
+- `abs:` - Abstract
+- `cat:` - Category
+- `all:` - All fields (default)
+- `co:` - Comment
+- `jr:` - Journal reference
+- `id:` - arXiv ID
+
+**Boolean operators** (must be UPPERCASE):
+```
+ti:transformer AND abs:attention
+au:bengio OR au:lecun
+cat:cs.LG ANDNOT cat:cs.CV
+```
+
+**Grouping with parentheses:**
+```
+(ti:sparse AND ti:autoencoder) AND cat:cs.LG
+au:anthropic AND (abs:interpretability OR abs:alignment)
+```
+
+**Examples:**
+```python
+from scripts.arxiv_search import ArxivSearcher
+
+searcher = ArxivSearcher()
+
+# Papers about SAEs in ML
+results = searcher.search(
+    query="ti:sparse autoencoder AND cat:cs.LG",
+    max_results=50,
+    sort_by="submittedDate"
+)
+
+# Specific author in specific field
+results = searcher.search(
+    query="au:neel nanda AND cat:cs.LG",
+    max_results=20
+)
+
+# Complex boolean query
+results = searcher.search(
+    query="(abs:RLHF OR abs:reinforcement learning from human feedback) AND cat:cs.CL",
+    max_results=100
+)
+```
+
+## Output Format
+
+All searches return structured JSON:
+

+
+## Common Usage Patterns
+
+### Literature Review Workflow
+
+```python
+from scripts.arxiv_search import ArxivSearcher
+import json
+
+searcher = ArxivSearcher()
+
+# 1. Broad search
+results = searcher.search(
+    query="abs:mechanistic interpretability AND cat:cs.LG",
+    max_results=200,
+    sort_by="submittedDate"
+)
+
+# 2. Save results
+with open("interp_papers.json", "w") as f:
+    json.dump({"result_count": len(results), "results": results}, f, indent=2)
+
+# 3. Filter and analyze
+import pandas as pd
+df = pd.DataFrame(results)
+print(f"Total papers: {len(df)}")
+print(f"Date range: {df['published'].min()} to {df['published'].max()}")
+print(f"\nTop categories:")
+print(df["primary_category"].value_counts().head(10))
+```
+
+### Track a Research Group
+
+```python
+searcher = ArxivSearcher()
+
+groups = {
+    "anthropic": "au:anthropic AND (cat:cs.LG OR cat:cs.CL)",
+    "openai": "au:openai AND cat:cs.CL",
+    "deepmind": "au:deepmind AND cat:cs.LG",
+}
+
+for name, query in groups.items():
+    results = searcher.search(query=query, max_results=50, sort_by="submittedDate")
+    print(f"{name}: {len(results)} recent papers")
+```
+
+### Monitor New Submissions
+
+```python
+searcher = ArxivSearcher()
+
+# Most recent ML papers
+results = searcher.search(
+    query="cat:cs.LG",
+    max_results=50,
+    sort_by="submittedDate",
+    sort_order="descending"
+)
+
+for paper in results[:10]:
+    print(f"[{paper['published'][:10]}] {paper['title']}")
+    print(f"  {paper['abs_url']}\n")
+```
+
+## Python API
+
+```python
+from scripts.arxiv_search import ArxivSearcher
+
+searcher = ArxivSearcher(verbose=True)
+
+# Free-form query (uses arXiv query syntax)
+results = searcher.search(query="...", max_results=50)
+
+# Lookup by ID
+papers = searcher.get_by_ids(["2309.10668", "2406.04093"])
+
+# Download PDF
+searcher.download_pdf("2309.10668", "paper.pdf")
+
+# Build query from components
+query = ArxivSearcher.build_query(
+    title="sparse autoencoder",
+    author="anthropic",
+    category="cs.LG"
+)
+results = searcher.search(query=query, max_results=20)
+```
+
+## Best Practices
+
+1. **Respect rate limits**: The API requests 3-second delays between calls. The script handles this automatically.
+2. **Use category filters**: Dramatically reduces noise. `cs.LG` is where most ML papers live.
+3. **Cache results**: Save to JSON to avoid re-fetching.
+4. **Use `sort_by=submittedDate`** for recent papers, `relevance` for keyword searches.
+5. **Max 300 results per query**: arXiv API caps at this. For larger sets, paginate with `start` parameter.
+6. **arXiv IDs**: Use bare IDs (`2309.10668`), not full URLs, in programmatic code.
+7. **Combine with openalex-database**: For citation counts and impact metrics arXiv doesn't provide.
+
+## Limitations
+
+- **No full-text search**: Only searches metadata (title, abstract, authors, comments)
+- **No citation data**: Use openalex-database or Semantic Scholar for citations
+- **Max 300 results**: Per query. Use pagination for larger sets.
+- **Rate limited**: ~1 request per 3 seconds recommended
+- **Atom XML responses**: The script parses these into JSON automatically
+- **Search lag**: New papers may take hours to appear in API results

+# arXiv API Reference
+
+## Overview
+
+The arXiv API provides programmatic access to preprint metadata via an Atom XML feed. It supports search queries with field-specific operators, boolean logic, ID-based retrieval, sorting, and pagination. No authentication required.
+
+## Base URL
+
+```
+http://export.arxiv.org/api/query
+```
+
+## Rate Limiting
+
+- Recommended: **1 request per 3 seconds**
+- Aggressive crawling will result in temporary IP bans
+- Use `time.sleep(3)` between requests
+- Include a descriptive `User-Agent` header
+
+## Query Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `search_query` | Query string with field prefixes and boolean operators | (none) |
+| `id_list` | Comma-separated arXiv IDs | (none) |
+| `start` | Starting index for pagination (0-based) | `0` |
+| `max_results` | Number of results to return (max 300) | `10` |
+| `sortBy` | Sort field: `relevance`, `lastUpdatedDate`, `submittedDate` | `relevance` |
+| `sortOrder` | Sort direction: `ascending`, `descending` | `descending` |
+
+**Note**: `search_query` and `id_list` can be used together (results are ANDed) or separately.
+
+## Search Query Syntax
+
+### Field Prefixes
+
+| Prefix | Field | Example |
+|--------|-------|---------|
+| `ti:` | Title | `ti:transformer` |
+| `au:` | Author | `au:bengio` |
+| `abs:` | Abstract | `abs:attention mechanism` |
+| `co:` | Comment | `co:accepted at NeurIPS` |
+| `jr:` | Journal Reference | `jr:Nature` |
+| `cat:` | Category | `cat:cs.LG` |
+| `all:` | All fields | `all:deep learning` |
+| `id:` | arXiv ID | `id:2309.10668` |
+
+### Boolean Operators
+
+Operators **must** be uppercase:
+
+```
+ti:transformer AND abs:attention           # Both conditions
+au:bengio OR au:lecun                      # Either condition
+cat:cs.LG ANDNOT cat:cs.CV                # Exclude category
+```
+
+### Grouping
+
+Use parentheses for complex queries:
+
+```
+(ti:sparse AND ti:autoencoder) AND cat:cs.LG
+au:anthropic AND (abs:interpretability OR abs:alignment)
+(cat:cs.LG OR cat:cs.CL) AND ti:reinforcement learning
+```
+
+### Phrase Search
+
+Quotes for exact phrases:
+
+```
+ti:"sparse autoencoder"
+au:"Yoshua Bengio"
+abs:"reinforcement learning from human feedback"
+```
+
+### Wildcards
+
+Not supported by the arXiv API. Use broader terms and filter client-side.

+## Pagination
+
+The API returns at most 300 results per request. For larger result sets, paginate:
+
+```python
+all_results = []
+start = 0
+batch_size = 100
+
+while True:
+    params = {
+        "search_query": "cat:cs.LG",
+        "start": start,
+        "max_results": batch_size,
+        "sortBy": "submittedDate",
+        "sortOrder": "descending",
+    }
+    results = fetch(params)  # your fetch function
+    if not results:
+        break
+    all_results.extend(results)
+    start += batch_size
+    time.sleep(3)  # respect rate limit
+```
+
+The total number of results available is in the `opensearch:totalResults` element of the feed.

+## arXiv ID Formats
+
+| Format | Era | Example |
+|--------|-----|---------|
+| `YYMM.NNNNN` | 2015+ | `2309.10668` |
+| `YYMM.NNNN` | 2007-2014 | `0706.0001` |
+| `archive/YYMMNNN` | Pre-2007 | `hep-th/9901001` |
+
+All formats are accepted by the API.
+
+## Common Pitfalls
+
+1. **Boolean operators must be UPPERCASE**: `AND`, `OR`, `ANDNOT` (lowercase is treated as search terms)
+2. **URL encoding**: Spaces in queries must be encoded as `+` or `%20`
+3. **No full-text search**: The API only searches metadata (title, abstract, authors, etc.)
+4. **Empty result placeholder**: When no results are found, arXiv may return a single entry with an empty title and the id `http://arxiv.org/api/errors` - filter this out
+5. **Version numbering**: `published` date is v1 submission; `updated` is latest version date
+6. **Rate limiting**: Exceeding limits can result in 403 errors or temporary bans
+7. **Max 300 per request**: Even if `max_results` is set higher, only 300 are returned

-
-## Overview
-
-A .docx file is a ZIP archive containing XML files and resources. Create, edit, or analyze Word documents using text extraction, raw XML access, or redlining workflows. Apply this skill for professional document processing, tracked changes, and content manipulation.
-
-## Visual Enhancement with Scientific Schematics
-
-**When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.**
-
-If your document does not already contain schematics or diagrams:
-- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
-- Simply describe your desired diagram in natural language
-- Nano Banana Pro will automatically generate, review, and refine the schematic
-
-**For new documents:** Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.
-
-**How to generate schematics:**
-```bash
-python scripts/generate_schematic.py "your diagram description" -o figures/output.png
-```
-
-The AI will automatically:
-- Create publication-quality images with proper formatting
-- Review and refine through multiple iterations
-- Ensure accessibility (colorblind-friendly, high contrast)
-- Save outputs in the figures/ directory
-
-**When to add schematics:**
-- Document workflow diagrams
-- Process flowcharts
-- System architecture illustrations
-- Data flow diagrams
-- Organizational structure diagrams
-- Any complex concept that benefits from visualization
-
-For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.
-
----
-
-## Workflow Decision Tree
-
-### Reading/Analyzing Content
-Use "Text extraction" or "Raw XML access" sections below
-
-### Creating New Document
-Use "Creating a new Word document" workflow
-
-### Editing Existing Document
-- **Your own document + simple changes**
-  Use "Basic OOXML editing" workflow
-
-- **Someone else's document**
-  Use **"Redlining workflow"** (recommended default)
-
-- **Legal, academic, business, or government docs**
-  Use **"Redlining workflow"** (required)
-
-## Reading and analyzing content
-
-### Text extraction
-To read the text contents of a document, convert the document to markdown using pandoc. Pandoc provides excellent support for preserving document structure and can show tracked changes:
-
-```bash
-# Convert document to markdown with tracked changes
-pandoc --track-changes=all path-to-file.docx -o output.md
-# Options: --track-changes=accept/reject/all
-```
-
-### Raw XML access
-Raw XML access is required for: comments, complex formatting, document structure, embedded media, and metadata. For any of these features, unpack a document and read its raw XML contents.
-
-#### Unpacking a file
-`python ooxml/scripts/unpack.py <office_file> <output_directory>`
-
-#### Key file structures
-* `word/document.xml` - Main document contents
-* `word/comments.xml` - Comments referenced in document.xml
-* `word/media/` - Embedded images and media files
-* Tracked changes use `<w:ins>` (insertions) and `<w:del>` (deletions) tags
-
-## Creating a new Word document
-
-When creating a new Word document from scratch, use **docx-js**, which allows you to create Word documents using JavaScript/TypeScript.
-
-### Workflow
-1. **MANDATORY - READ ENTIRE FILE**: Read [`docx-js.md`](docx-js.md) (~500 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Read the full file content for detailed syntax, critical formatting rules, and best practices before proceeding with document creation.
-2. Create a JavaScript/TypeScript file using Document, Paragraph, TextRun components (You can assume all dependencies are installed, but if not, refer to the dependencies section below)
-3. Export as .docx using Packer.toBuffer()
-
-## Editing an existing Word document
-
-When editing an existing Word document, use the **Document library** (a Python library for OOXML manipulation). The library automatically handles infrastructure setup and provides methods for document manipulation. For complex scenarios, you can access the underlying DOM directly through the library.
-
-### Workflow
-1. **MANDATORY - READ ENTIRE FILE**: Read [`ooxml.md`](ooxml.md) (~600 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Read the full file content for the Document library API and XML patterns for directly editing document files.
-2. Unpack the document: `python ooxml/scripts/unpack.py <office_file> <output_directory>`
-3. Create and run a Python script using the Document library (see "Document Library" section in ooxml.md)
-4. Pack the final document: `python ooxml/scripts/pack.py <input_directory> <office_file>`
-
-The Document library provides both high-level methods for common operations and direct DOM access for complex scenarios.
-
-## Redlining workflow for document review
-
-This workflow allows planning comprehensive tracked changes using markdown before implementing them in OOXML. **CRITICAL**: For complete tracked changes, implement ALL changes systematically.
-
-**Batching Strategy**: Group related changes into batches of 3-10 changes. This makes debugging manageable while maintaining efficiency. Test each batch before moving to the next.
-
-**Principle: Minimal, Precise Edits**
-When implementing tracked changes, only mark text that actually changes. Repeating unchanged text makes edits harder to review and appears unprofessional. Break replacements into: [unchanged text] + [deletion] + [insertion] + [unchanged text]. Preserve the original run's RSID for unchanged text by extracting the `<w:r>` element from the original and reusing it.
-
-Example - Changing "30 days" to "60 days" in a sentence:
-```python
-# BAD - Replaces entire sentence
-'<w:del><w:r><w:delText>The term is 30 days.</w:delText></w:r></w:del><w:ins><w:r><w:t>The term is 60 days.</w:t></w:r></w:ins>'
-
-# GOOD - Only marks what changed, preserves original <w:r> for unchanged text
-'<w:r w:rsidR="00AB12CD"><w:t>The term is </w:t></w:r><w:del><w:r><w:delText>30</w:delText></w:r></w:del><w:ins><w:r><w:t>60</w:t></w:r></w:ins><w:r w:rsidR="00AB12CD"><w:t> days.</w:t></w:r>'
-```
-
-### Tracked changes workflow
-
-1. **Get markdown representation**: Convert document to markdown with tracked changes preserved:
-   ```bash
-   pandoc --track-changes=all path-to-file.docx -o current.md
-   ```
-
-2. **Identify and group changes**: Review the document and identify ALL changes needed, organizing them into logical batches:
-
-   **Location methods** (for finding changes in XML):
-   - Section/heading numbers (e.g., "Section 3.2", "Article IV")
-   - Paragraph identifiers if numbered
-   - Grep patterns with unique surrounding text
-   - Document structure (e.g., "first paragraph", "signature block")
-   - **DO NOT use markdown line numbers** - they don't map to XML structure
-
-   **Batch organization** (group 3-10 related changes per batch):
-   - By section: "Batch 1: Section 2 amendments", "Batch 2: Section 5 updates"
-   - By type: "Batch 1: Date corrections", "Batch 2: Party name changes"
-   - By complexity: Start with simple text replacements, then tackle complex structural changes
-   - Sequential: "Batch 1: Pages 1-3", "Batch 2: Pages 4-6"
-
-3. **Read documentation and unpack**:
-   - **MANDATORY - READ ENTIRE FILE**: Read [`ooxml.md`](ooxml.md) (~600 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Pay special attention to the "Document Library" and "Tracked Change Patterns" sections.
-   - **Unpack the document**: `python ooxml/scripts/unpack.py <file.docx> <dir>`
-   - **Note the suggested RSID**: The unpack script will suggest an RSID to use for your tracked changes. Copy this RSID for use in step 4b.
-
-4. **Implement changes in batches**: Group changes logically (by section, by type, or by proximity) and implement them together in a single script. This approach:
-   - Makes debugging easier (smaller batch = easier to isolate errors)
-   - Allows incremental progress
-   - Maintains efficiency (batch size of 3-10 changes works well)
-
-   **Suggested batch groupings:**
-   - By document section (e.g., "Section 3 changes", "Definitions", "Termination clause")
-   - By change type (e.g., "Date changes", "Party name updates", "Legal term replacements")
-   - By proximity (e.g., "Changes on pages 1-3", "Changes in first half of document")
-
-   For each batch of related changes:
-
-   **a. Map text to XML**: Grep for text in `word/document.xml` to verify how text is split across `<w:r>` elements.
-
-   **b. Create and run script**: Use `get_node` to find nodes, implement changes, then `doc.save()`. See **"Document Library"** section in ooxml.md for patterns.
-
-   **Note**: Always grep `word/document.xml` immediately before writing a script to get current line numbers and verify text content. Line numbers change after each script run.
-
-5. **Pack the document**: After all batches are complete, convert the unpacked directory back to .docx:
-   ```bash
-   python ooxml/scripts/pack.py unpacked reviewed-document.docx
-   ```
-
-6. **Final verification**: Do a comprehensive check of the complete document:
-   - Convert final document to markdown:
-     ```bash
-     pandoc --track-changes=all reviewed-document.docx -o verification.md
-     ```
-   - Verify ALL changes were applied correctly:
-     ```bash
-     grep "original phrase" verification.md  # Should NOT find it
-     grep "replacement phrase" verification.md  # Should find it
-     ```
-   - Check that no unintended changes were introduced
-
-
-## Converting Documents to Images
-
-To visually analyze Word documents, convert them to images using a two-step process:
-
-1. **Convert DOCX to PDF**:
-   ```bash
-   soffice --headless --convert-to pdf document.docx
-   ```
-
-2. **Convert PDF pages to JPEG images**:
-   ```bash
-   pdftoppm -jpeg -r 150 document.pdf page
-   ```
-   This creates files like `page-1.jpg`, `page-2.jpg`, etc.
-
-Options:
-- `-r 150`: Sets resolution to 150 DPI (adjust for quality/size balance)
-- `-jpeg`: Output JPEG format (use `-png` for PNG if preferred)
-- `-f N`: First page to convert (e.g., `-f 2` starts from page 2)
-- `-l N`: Last page to convert (e.g., `-l 5` stops at page 5)
-- `page`: Prefix for output files
-
-Example for specific range:
-```bash
-pdftoppm -jpeg -r 150 -f 2 -l 5 document.pdf page  # Converts only pages 2-5
-```
-
-## Code Style Guidelines
-**IMPORTANT**: When generating code for DOCX operations:
-- Write concise code
-- Avoid verbose variable names and redundant operations
-- Avoid unnecessary print statements
-
-## Dependencies
-
-Required dependencies (install if not available):
-
-- **pandoc**: `sudo apt-get install pandoc` (for text extraction)
-- **docx**: `npm install -g docx` (for creating new documents)
-- **LibreOffice**: `sudo apt-get install libreoffice` (for PDF conversion)
-- **Poppler**: `sudo apt-get install poppler-utils` (for pdftoppm to convert PDF to images)
-- **defusedxml**: `pip install defusedxml` (for secure XML parsing)

-**Professional Font Combinations:**
-- **Arial (Headers) + Arial (Body)** - Most universally supported, clean and professional
-- **Times New Roman (Headers) + Arial (Body)** - Classic serif headers with modern sans-serif body
-- **Georgia (Headers) + Verdana (Body)** - Optimized for screen reading, elegant contrast
-
-**Key Styling Principles:**
-- **Override built-in styles**: Use exact IDs like "Heading1", "Heading2", "Heading3" to override Word's built-in heading styles
-- **HeadingLevel constants**: `HeadingLevel.HEADING_1` uses "Heading1" style, `HeadingLevel.HEADING_2` uses "Heading2" style, etc.
-- **Include outlineLevel**: Set `outlineLevel: 0` for H1, `outlineLevel: 1` for H2, etc. to ensure TOC works correctly
-- **Use custom styles** instead of inline formatting for consistency
-- **Set a default font** using `styles.default.document.run.font` - Arial is universally supported
-- **Establish visual hierarchy** with different font sizes (titles > headers > body)
-- **Add proper spacing** with `before` and `after` paragraph spacing
-- **Use colors sparingly**: Default to black (000000) and shades of gray for titles and headings (heading 1, heading 2, etc.)
-- **Set consistent margins** (1440 = 1 inch is standard)

-## Lists (ALWAYS USE PROPER LISTS - NEVER USE UNICODE BULLETS)
-```javascript
-// Bullets - ALWAYS use the numbering config, NOT unicode symbols
-// CRITICAL: Use LevelFormat.BULLET constant, NOT the string "bullet"
-const doc = new Document({
-  numbering: {
-    config: [
-      { reference: "bullet-list",
-        levels: [{ level: 0, format: LevelFormat.BULLET, text: "•", alignment: AlignmentType.LEFT,

-      new Paragraph({ numbering: { reference: "first-numbered-list", level: 0 },
-        children: [new TextRun("Second numbered item")] }),
-      // ⚠️ CRITICAL: Different reference = INDEPENDENT list that restarts at 1
-      // Same reference = CONTINUES previous numbering
-      new Paragraph({ numbering: { reference: "second-numbered-list", level: 0 },
-        children: [new TextRun("Starts at 1 again (because different reference)")] })
-    ]
-  }]
-});
-
-// ⚠️ CRITICAL NUMBERING RULE: Each reference creates an INDEPENDENT numbered list
-// - Same reference = continues numbering (1, 2, 3... then 4, 5, 6...)
-// - Different reference = restarts at 1 (1, 2, 3... then 1, 2, 3...)
-// Use unique reference names for each separate numbered section!
-
-// ⚠️ CRITICAL: NEVER use unicode bullets - they create fake lists that don't work properly
-// new TextRun("• Item")           // WRONG
-// new SymbolRun({ char: "2022" }) // WRONG
-// ✅ ALWAYS use numbering config with LevelFormat.BULLET for real Word lists
-```

-## Tables
-```javascript
-// Complete table with margins, borders, headers, and bullet points

-        })
-      ]
-    })

-})
-```
-
-**IMPORTANT: Table Width & Borders**
-- Use BOTH `columnWidths: [width1, width2, ...]` array AND `width: { size: X, type: WidthType.DXA }` on each cell
-- Values in DXA (twentieths of a point): 1440 = 1 inch, Letter usable width = 9360 DXA (with 1" margins)
-- Apply borders to individual `TableCell` elements, NOT the `Table` itself
-
-**Precomputed Column Widths (Letter size with 1" margins = 9360 DXA total):**
-- **2 columns:** `columnWidths: [4680, 4680]` (equal width)
-- **3 columns:** `columnWidths: [3120, 3120, 3120]` (equal width)

-## Links & Navigation
-```javascript
-// TOC (requires headings) - CRITICAL: Use HeadingLevel only, NOT custom styles
-// ❌ WRONG: new Paragraph({ heading: HeadingLevel.HEADING_1, style: "customHeader", children: [new TextRun("Title")] })
-// ✅ CORRECT: new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Title")] })
-new TableOfContents("Table of Contents", { hyperlink: true, headingStyleRange: "1-3" }),
-
-// External link
-new Paragraph({
-  children: [new ExternalHyperlink({
-    children: [new TextRun({ text: "Google", style: "Hyperlink" })],
-    link: "https://www.google.com"
-  })]
-}),
-
-// Internal link & bookmark
-new Paragraph({
-  children: [new InternalHyperlink({
-    children: [new TextRun({ text: "Go to Section", style: "Hyperlink" })],

-  })]
-}),
-new Paragraph({
-  children: [new TextRun("Section Content")],
-  bookmark: { id: "section1", name: "section1" }
-}),
-```
-
-## Images & Media
-```javascript
-// Basic image with sizing & positioning
-// CRITICAL: Always specify 'type' parameter - it's REQUIRED for ImageRun
-new Paragraph({
-  alignment: AlignmentType.CENTER,
-  children: [new ImageRun({
-    type: "png", // NEW REQUIREMENT: Must specify image type (png, jpg, jpeg, gif, bmp, svg)
-    data: fs.readFileSync("image.png"),
-    transformation: { width: 200, height: 150, rotation: 0 }, // rotation in degrees
-    altText: { title: "Logo", description: "Company logo", name: "Name" } // IMPORTANT: All three fields are required
-  })]
-})
-```
-
-## Page Breaks
-```javascript
-// Manual page break
-new Paragraph({ children: [new PageBreak()] }),
-
-// Page break before paragraph
-new Paragraph({
-  pageBreakBefore: true,
-  children: [new TextRun("This starts on a new page")]
-})
-
-// ⚠️ CRITICAL: NEVER use PageBreak standalone - it will create invalid XML that Word cannot open
-// ❌ WRONG: new PageBreak() 
-// ✅ CORRECT: new Paragraph({ children: [new PageBreak()] })
-```
-
-## Headers/Footers & Page Setup
-```javascript
-const doc = new Document({
-  sections: [{
-    properties: {
-      page: {
-        margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 }, // 1440 = 1 inch
-        size: { orientation: PageOrientation.LANDSCAPE },
-        pageNumbers: { start: 1, formatType: "decimal" } // "upperRoman", "lowerRoman", "upperLetter", "lowerLetter"
-      }
-    },
-    headers: {
-      default: new Header({ children: [new Paragraph({ 
-        alignment: AlignmentType.RIGHT,
-        children: [new TextRun("Header Text")]
-      })] })
-    },
-    footers: {
-      default: new Footer({ children: [new Paragraph({ 
-        alignment: AlignmentType.CENTER,
-        children: [new TextRun("Page "), new TextRun({ children: [PageNumber.CURRENT] }), new TextRun(" of "), new TextRun({ children: [PageNumber.TOTAL_PAGES] })]
-      })] })
-    },
-    children: [/* content */]
-  }]
-});
-```
-
-## Tabs
-```javascript
-new Paragraph({
-  tabStops: [
-    { type: TabStopType.LEFT, position: TabStopPosition.MAX / 4 },
-    { type: TabStopType.CENTER, position: TabStopPosition.MAX / 2 },
-    { type: TabStopType.RIGHT, position: TabStopPosition.MAX * 3 / 4 }
-  ],
-  children: [new TextRun("Left\tCenter\tRight")]
-})
-```
-
-## Constants & Quick Reference
-- **Underlines:** `SINGLE`, `DOUBLE`, `WAVY`, `DASH`
-- **Borders:** `SINGLE`, `DOUBLE`, `DASHED`, `DOTTED`  
-- **Numbering:** `DECIMAL` (1,2,3), `UPPER_ROMAN` (I,II,III), `LOWER_LETTER` (a,b,c)
-- **Tabs:** `LEFT`, `CENTER`, `RIGHT`, `DECIMAL`
-- **Symbols:** `"2022"` (•), `"00A9"` (©), `"00AE"` (®), `"2122"` (™), `"00B0"` (°), `"F070"` (✓), `"F0FC"` (✗)
-
-## Critical Issues & Common Mistakes
-- **CRITICAL: PageBreak must ALWAYS be inside a Paragraph** - standalone PageBreak creates invalid XML that Word cannot open
-- **ALWAYS use ShadingType.CLEAR for table cell shading** - Never use ShadingType.SOLID (causes black background).
-- Measurements in DXA (1440 = 1 inch) | Each table cell needs ≥1 Paragraph | TOC requires HeadingLevel styles only
-- **ALWAYS use custom styles** with Arial font for professional appearance and proper visual hierarchy
-- **ALWAYS set a default font** using `styles.default.document.run.font` - Arial recommended
-- **ALWAYS use columnWidths array for tables** + individual cell widths for compatibility
-- **NEVER use unicode symbols for bullets** - always use proper numbering configuration with `LevelFormat.BULLET` constant (NOT the string "bullet")
-- **NEVER use \n for line breaks anywhere** - always use separate Paragraph elements for each line
-- **ALWAYS use TextRun objects within Paragraph children** - never use text property directly on Paragraph
-- **CRITICAL for images**: ImageRun REQUIRES `type` parameter - always specify "png", "jpg", "jpeg", "gif", "bmp", or "svg"
-- **CRITICAL for bullets**: Must use `LevelFormat.BULLET` constant, not string "bullet", and include `text: "•"` for the bullet character
-- **CRITICAL for numbering**: Each numbering reference creates an INDEPENDENT list. Same reference = continues numbering (1,2,3 then 4,5,6). Different reference = restarts at 1 (1,2,3 then 1,2,3). Use unique reference names for each separate numbered section!
-- **CRITICAL for TOC**: When using TableOfContents, headings must use HeadingLevel ONLY - do NOT add custom styles to heading paragraphs or TOC will break
-- **Tables**: Set `columnWidths` array + individual cell widths, apply borders to cells not table
-- **Set table margins at TABLE level** for consistent cell padding (avoids repetition per cell)

-**Important: Read this entire document before starting.** This document covers:
-- [Technical Guidelines](#technical-guidelines) - Schema compliance rules and validation requirements
-- [Document Content Patterns](#document-content-patterns) - XML patterns for headings, lists, tables, formatting, etc.
-- [Document Library (Python)](#document-library-python) - Recommended approach for OOXML manipulation with automatic infrastructure setup

-
-## Technical Guidelines
-
-### Schema Compliance
-- **Element ordering in `<w:pPr>`**: `<w:pStyle>`, `<w:numPr>`, `<w:spacing>`, `<w:ind>`, `<w:jc>`
-- **Whitespace**: Add `xml:space='preserve'` to `<w:t>` elements with leading/trailing spaces
-- **Unicode**: Escape characters in ASCII content: `"` becomes `&#8220;`
-  - **Character encoding reference**: Curly quotes `""` become `&#8220;&#8221;`, apostrophe `'` becomes `&#8217;`, em-dash `—` becomes `&#8212;`
-- **Tracked changes**: Use `<w:del>` and `<w:ins>` tags with `w:author="Scientific-Writer"` outside `<w:r>` elements
-  - **Critical**: `<w:ins>` closes with `</w:ins>`, `<w:del>` closes with `</w:del>` - never mix
-  - **RSIDs must be 8-digit hex**: Use values like `00AB1234` (only 0-9, A-F characters)
-  - **trackRevisions placement**: Add `<w:trackRevisions/>` after `<w:proofState>` in settings.xml
-- **Images**: Add to `word/media/`, reference in `document.xml`, set dimensions to prevent overflow

-### Links (Hyperlinks)
-
-**IMPORTANT**: All hyperlinks (both internal and external) require the Hyperlink style to be defined in styles.xml. Without this style, links will look like regular text instead of blue underlined clickable links.
-
-**External Links:**
-```xml
-<!-- In document.xml -->
-<w:hyperlink r:id="rId5">
-  <w:r>
-    <w:rPr><w:rStyle w:val="Hyperlink"/></w:rPr>
-    <w:t>Link Text</w:t>
-  </w:r>
-</w:hyperlink>
-
-<!-- In word/_rels/document.xml.rels -->
-<Relationship Id="rId5" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink" 
-              Target="https://www.example.com/" TargetMode="External"/>
-```
-
-**Internal Links:**
-
-```xml
-<!-- Link to bookmark -->
-<w:hyperlink w:anchor="myBookmark">
-  <w:r>
-    <w:rPr><w:rStyle w:val="Hyperlink"/></w:rPr>
-    <w:t>Link Text</w:t>
-  </w:r>
-</w:hyperlink>
-
-<!-- Bookmark target -->
-<w:bookmarkStart w:id="0" w:name="myBookmark"/>
-<w:r><w:t>Target content</w:t></w:r>
-<w:bookmarkEnd w:id="0"/>
-```
-
-**Hyperlink Style (required in styles.xml):**
-```xml
-<w:style w:type="character" w:styleId="Hyperlink">
-  <w:name w:val="Hyperlink"/>
-  <w:basedOn w:val="DefaultParagraphFont"/>
-  <w:uiPriority w:val="99"/>
-  <w:unhideWhenUsed/>
-  <w:rPr>
-    <w:color w:val="467886" w:themeColor="hyperlink"/>
-    <w:u w:val="single"/>
-  </w:rPr>
-</w:style>
-```
-
-## Document Library (Python)
-
-Use the Document class from `scripts/document.py` for all tracked changes and comments. It automatically handles infrastructure setup (people.xml, RSIDs, settings.xml, comment files, relationships, content types). Only use direct XML manipulation for complex scenarios not supported by the library.
-
-**Working with Unicode and Entities:**
-- **Searching**: Both entity notation and Unicode characters work - `contains="&#8220;Company"` and `contains="\u201cCompany"` find the same text
-- **Replacing**: Use either entities (`&#8220;`) or Unicode (`\u201c`) - both work and will be converted appropriately based on the file's encoding (ascii → entities, utf-8 → Unicode)
-
-### Initialization
-
-**Find the docx skill root** (directory containing `scripts/` and `ooxml/`):
-```bash
-# Search for document.py to locate the skill root
-# Note: /mnt/skills is used here as an example; check your context for the actual location
-find /mnt/skills -name "document.py" -path "*/docx/scripts/*" 2>/dev/null | head -1
-# Example output: /mnt/skills/docx/scripts/document.py
-# Skill root is: /mnt/skills/docx
-```
-
-**Run your script with PYTHONPATH** set to the docx skill root:
-```bash
-PYTHONPATH=/mnt/skills/docx python your_script.py
-```
-
-**In your script**, import from the skill root:
-```python
-from scripts.document import Document, DocxXMLEditor
-
-# Basic initialization (automatically creates temp copy and sets up infrastructure)
-doc = Document('unpacked')
-
-# Customize author and initials
-doc = Document('unpacked', author="John Doe", initials="JD")
-
-# Enable track revisions mode
-doc = Document('unpacked', track_revisions=True)
-
-# Specify custom RSID (auto-generated if not provided)
-doc = Document('unpacked', rsid="07DC5ECB")
-```
-
-### Creating Tracked Changes
-
-**CRITICAL**: Only mark text that actually changes. Keep ALL unchanged text outside `<w:del>`/`<w:ins>` tags. Marking unchanged text makes edits unprofessional and harder to review.
-
-**Attribute Handling**: The Document class auto-injects attributes (w:id, w:date, w:rsidR, w:rsidDel, w16du:dateUtc, xml:space) into new elements. When preserving unchanged text from the original document, copy the original `<w:r>` element with its existing attributes to maintain document integrity.
-
-**Method Selection Guide**:
-- **Adding your own changes to regular text**: Use `replace_node()` with `<w:del>`/`<w:ins>` tags, or `suggest_deletion()` for removing entire `<w:r>` or `<w:p>` elements
-- **Partially modifying another author's tracked change**: Use `replace_node()` to nest your changes inside their `<w:ins>`/`<w:del>`
-- **Completely rejecting another author's insertion**: Use `revert_insertion()` on the `<w:ins>` element (NOT `suggest_deletion()`)
-- **Completely rejecting another author's deletion**: Use `revert_deletion()` on the `<w:del>` element to restore deleted content using tracked changes
-

-doc["word/document.xml"].replace_node(node, replacement)
-
-# Delete entire run (use only when deleting all content; use replace_node for partial deletions)

-# doc["word/document.xml"].insert_after(target_para, spacing + tracked_para)
-```
-
-### Adding Comments
-
-```python
-# Add comment spanning two existing tracked changes
-# Note: w:id is auto-generated. Only search by w:id if you know it from XML inspection
-start_node = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "1"})
-end_node = doc["word/document.xml"].get_node(tag="w:ins", attrs={"w:id": "2"})
-doc.add_comment(start=start_node, end=end_node, text="Explanation of this change")
-
-# Add comment on a paragraph
-para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
-doc.add_comment(start=para, end=para, text="Comment on this paragraph")
-
-# Add comment on newly created tracked change
-# First create the tracked change
-node = doc["word/document.xml"].get_node(tag="w:r", contains="old")
-new_nodes = doc["word/document.xml"].replace_node(
-    node,
-    '<w:del><w:r><w:delText>old</w:delText></w:r></w:del><w:ins><w:r><w:t>new</w:t></w:r></w:ins>'
-)
-# Then add comment on the newly created elements
-# new_nodes[0] is the <w:del>, new_nodes[1] is the <w:ins>
-doc.add_comment(start=new_nodes[0], end=new_nodes[1], text="Changed old to new per requirements")
-
-# Reply to existing comment
-doc.reply_to_comment(parent_comment_id=0, text="I agree with this change")
-```
-
-### Rejecting Tracked Changes
-
-**IMPORTANT**: Use `revert_insertion()` to reject insertions and `revert_deletion()` to restore deletions using tracked changes. Use `suggest_deletion()` only for regular unmarked content.
-
-```python
-# Reject insertion (wraps it in deletion)
-# Use this when another author inserted text that you want to delete
-ins = doc["word/document.xml"].get_node(tag="w:ins", attrs={"w:id": "5"})
-nodes = doc["word/document.xml"].revert_insertion(ins)  # Returns [ins]
-
-# Reject deletion (creates insertion to restore deleted content)
-# Use this when another author deleted text that you want to restore
-del_elem = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "3"})
-nodes = doc["word/document.xml"].revert_deletion(del_elem)  # Returns [del_elem, new_ins]
-
-# Reject all insertions in a paragraph
-para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
-nodes = doc["word/document.xml"].revert_insertion(para)  # Returns [para]
-
-# Reject all deletions in a paragraph
-para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
-nodes = doc["word/document.xml"].revert_deletion(para)  # Returns [para]
-```
-
-### Inserting Images
-
-**CRITICAL**: The Document class works with a temporary copy at `doc.unpacked_path`. Always copy images to this temp directory, not the original unpacked folder.
-
-```python
-from PIL import Image
-import shutil, os
-
-# Initialize document first
-doc = Document('unpacked')
-
-# Copy image and calculate full-width dimensions with aspect ratio
-media_dir = os.path.join(doc.unpacked_path, 'word/media')
-os.makedirs(media_dir, exist_ok=True)
-shutil.copy('image.png', os.path.join(media_dir, 'image1.png'))
-img = Image.open(os.path.join(media_dir, 'image1.png'))
-width_emus = int(6.5 * 914400)  # 6.5" usable width, 914400 EMUs/inch
-height_emus = int(width_emus * img.size[1] / img.size[0])
-
-# Add relationship and content type
-rels_editor = doc['word/_rels/document.xml.rels']
-next_rid = rels_editor.get_next_rid()
-rels_editor.append_to(rels_editor.dom.documentElement,
-    f'<Relationship Id="{next_rid}" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="media/image1.png"/>')
-doc['[Content_Types].xml'].append_to(doc['[Content_Types].xml'].dom.documentElement,
-    '<Default Extension="png" ContentType="image/png"/>')
-
-# Insert image
-node = doc["word/document.xml"].get_node(tag="w:p", line_number=100)
-doc["word/document.xml"].insert_after(node, f'''<w:p>
-  <w:r>

-        </a:graphic>
-      </wp:inline>
-    </w:drawing>
-  </w:r>
-</w:p>''')
-```
-
-### Getting Nodes
-
-```python
-# By text content
-node = doc["word/document.xml"].get_node(tag="w:p", contains="specific text")
-
-# By line range
-para = doc["word/document.xml"].get_node(tag="w:p", line_number=range(100, 150))
-
-# By attributes
-node = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "1"})
-
-# By exact line number (must be line number where tag opens)
-para = doc["word/document.xml"].get_node(tag="w:p", line_number=42)
-
-# Combine filters
-node = doc["word/document.xml"].get_node(tag="w:r", line_number=range(40, 60), contains="text")
-
-# Disambiguate when text appears multiple times - add line_number range
-node = doc["word/document.xml"].get_node(tag="w:r", contains="Section", line_number=range(2400, 2500))
-```
-
-### Saving
-
-```python
-# Save with automatic validation (copies back to original directory)
-doc.save()  # Validates by default, raises error if validation fails
-
-# Save to different location
-doc.save('modified-unpacked')
-
-# Skip validation (debugging only - needing this in production indicates XML issues)
-doc.save(validate=False)
-```
-
-### Direct DOM Manipulation
-
-For complex scenarios not covered by the library:
-
-```python
-# Access any XML file
-editor = doc["word/document.xml"]
-editor = doc["word/comments.xml"]
-
-# Direct DOM access (defusedxml.minidom.Document)
-node = doc["word/document.xml"].get_node(tag="w:p", line_number=5)
-parent = node.parentNode
-parent.removeChild(node)
-parent.appendChild(node)  # Move to end
-
-# General document manipulation (without tracked changes)
-old_node = doc["word/document.xml"].get_node(tag="w:p", contains="original text")
-doc["word/document.xml"].replace_node(old_node, "<w:p><w:r><w:t>replacement text</w:t></w:r></w:p>")
-
-# Multiple insertions - use return value to maintain order
-node = doc["word/document.xml"].get_node(tag="w:r", line_number=100)
-nodes = doc["word/document.xml"].insert_after(node, "<w:r><w:t>A</w:t></w:r>")
-nodes = doc["word/document.xml"].insert_after(nodes[-1], "<w:r><w:t>B</w:t></w:r>")
-nodes = doc["word/document.xml"].insert_after(nodes[-1], "<w:r><w:t>C</w:t></w:r>")
-# Results in: original_node, A, B, C
-```
-
-## Tracked Changes (Redlining)
-
-**Use the Document class above for all tracked changes.** The patterns below are for reference when constructing replacement XML strings.
-
-### Validation Rules
-The validator checks that the document text matches the original after reverting Scientific-Writer's changes. This means:
-- **NEVER modify text inside another author's `<w:ins>` or `<w:del>` tags**
-- **ALWAYS use nested deletions** to remove another author's insertions
-- **Every edit must be properly tracked** with `<w:ins>` or `<w:del>` tags
-
-### Tracked Change Patterns
-
-**CRITICAL RULES**:
-1. Never modify the content inside another author's tracked changes. Always use nested deletions.
-2. **XML Structure**: Always place `<w:del>` and `<w:ins>` at paragraph level containing complete `<w:r>` elements. Never nest inside `<w:r>` elements - this creates invalid XML that breaks document processing.
-
-**Text Insertion:**
-```xml
-<w:ins w:id="1" w:author="Scientific-Writer" w:date="2025-07-30T23:05:00Z" w16du:dateUtc="2025-07-31T06:05:00Z">
-  <w:r w:rsidR="00792858">
-    <w:t>inserted text</w:t>
-  </w:r>
-</w:ins>
-```
-
-**Text Deletion:**
-```xml
-<w:del w:id="2" w:author="Scientific-Writer" w:date="2025-07-30T23:05:00Z" w16du:dateUtc="2025-07-31T06:05:00Z">
-  <w:r w:rsidDel="00792858">
-    <w:delText>deleted text</w:delText>
-  </w:r>
-</w:del>
-```
-
-**Deleting Another Author's Insertion (MUST use nested structure):**
-```xml
-<!-- Nest deletion inside the original insertion -->
-<w:ins w:author="Jane Smith" w:id="16">
-  <w:del w:author="Scientific-Writer" w:id="40">
-    <w:r><w:delText>monthly</w:delText></w:r>
-  </w:del>
-</w:ins>
-<w:ins w:author="Scientific-Writer" w:id="41">
-  <w:r><w:t>weekly</w:t></w:r>
-</w:ins>
-```
-
-**Restoring Another Author's Deletion:**
-```xml
-<!-- Leave their deletion unchanged, add new insertion after it -->
-<w:del w:author="Jane Smith" w:id="50">
-  <w:r><w:delText>within 30 days</w:delText></w:r>
-</w:del>
-<w:ins w:author="Scientific-Writer" w:id="51">
-  <w:r><w:t>within 30 days</w:t></w:r>
-</w:ins>
-```

-    elem = editor.get_node(tag="w:r", line_number=519)
-    elem = editor.get_node(tag="w:p", line_number=range(100, 200))
-
-    # Find node by text content
-    elem = editor.get_node(tag="w:p", contains="specific text")
-
-    # Find node by attributes
-    elem = editor.get_node(tag="w:r", attrs={"w:id": "target"})
-
-    # Combine filters
-    elem = editor.get_node(tag="w:p", line_number=range(1, 50), contains="text")
-
-    # Replace, insert, or manipulate
-    new_elem = editor.replace_node(elem, "<w:r><w:t>new text</w:t></w:r>")
-    editor.insert_after(new_elem, "<w:r><w:t>more</w:t></w:r>")

-- Convert the PDF to PNGs (one image for each page) with this script (run from this file's directory):
-`python scripts/convert_pdf_to_images.py <file.pdf> <output_directory>`
-Then analyze the images to determine the purpose of each form field (make sure to convert the bounding box PDF coordinates to image coordinates).
-- Create a `field_values.json` file in this format with the values to be entered for each field:
-```
-[
-  {
-    "field_id": "last_name", // Must match the field_id from `extract_form_field_info.py`
-    "description": "The user's last name",
-    "page": 1, // Must match the "page" value in field_info.json
-    "value": "Simpson"

-    "field_id": "Checkbox12",
-    "description": "Checkbox to be checked if the user is 18 or over",
-    "page": 1,
-    "value": "/On" // If this is a checkbox, use its "checked_value" value to check it. If it's a radio button group, use one of the "value" values in "radio_options".
-  },
-  // more fields
-]
-```
-- Run the `fill_fillable_fields.py` script from this file's directory to create a filled-in PDF:
-`python scripts/fill_fillable_fields.py <input pdf> <field_values.json> <output pdf>`
-This script will verify that the field IDs and values you provide are valid; if it prints error messages, correct the appropriate fields and try again.
-
-# Non-fillable fields
-If the PDF doesn't have fillable form fields, you'll need to visually determine where the data should be added and create text annotations. Follow the below steps *exactly*. You MUST perform all of these steps to ensure that the the form is accurately completed. Details for each step are below.
-- Convert the PDF to PNG images and determine field bounding boxes.
-- Create a JSON file with field information and validation images showing the bounding boxes.
-- Validate the the bounding boxes.
-- Use the bounding boxes to fill in the form.
-
-## Step 1: Visual Analysis (REQUIRED)
-- Convert the PDF to PNG images. Run this script from this file's directory:
-`python scripts/convert_pdf_to_images.py <file.pdf> <output_directory>`
-The script will create a PNG image for each page in the PDF.
-- Carefully examine each PNG image and identify all form fields and areas where the user should enter data. For each form field where the user should enter text, determine bounding boxes for both the form field label, and the area where the user should enter text. The label and entry bounding boxes MUST NOT INTERSECT; the text entry box should only include the area where data should be entered. Usually this area will be immediately to the side, above, or below its label. Entry bounding boxes must be tall and wide enough to contain their text.
-
-These are some examples of form structures that you might see:
-
-*Label inside box*
-```
-┌────────────────────────┐
-│ Name:                  │
-└────────────────────────┘
-```
-The input area should be to the right of the "Name" label and extend to the edge of the box.
-
-*Label before line*
-```
-Email: _______________________
-```
-The input area should be above the line and include its entire width.
-
-*Label under line*
-```
-_________________________
-Name
-```
-The input area should be above the line and include the entire width of the line. This is common for signature and date fields.
-
-*Label above line*
-```
-Please enter any special requests:
-________________________________________________
-```
-The input area should extend from the bottom of the label to the line, and should include the entire width of the line.
-
-*Checkboxes*
-```
-Are you a US citizen? Yes □  No □
-```
-For checkboxes:
-- Look for small square boxes (□) - these are the actual checkboxes to target. They may be to the left or right of their labels.
-- Distinguish between label text ("Yes", "No") and the clickable checkbox squares.
-- The entry bounding box should cover ONLY the small square, not the text label.
-
-### Step 2: Create fields.json and validation images (REQUIRED)
-- Create a file named `fields.json` with information for the form fields and bounding boxes in this format:
-```
-{
-  "pages": [
-    {
-      "page_number": 1,
-      "image_width": (first page image width in pixels),
-      "image_height": (first page image height in pixels),
-    },
-    {
-      "page_number": 2,
-      "image_width": (second page image width in pixels),
-      "image_height": (second page image height in pixels),
-    }
-    // additional pages
-  ],
-  "form_fields": [
-    // Example for a text field.
-    {
-      "page_number": 1,
-      "description": "The user's last name should be entered here",
-      // Bounding boxes are [left, top, right, bottom]. The bounding boxes for the label and text entry should not overlap.
-      "field_label": "Last name",
-      "label_bounding_box": [30, 125, 95, 142],
-      "entry_bounding_box": [100, 125, 280, 142],
-      "entry_text": {
-        "text": "Johnson", // This text will be added as an annotation at the entry_bounding_box location
-        "font_size": 14, // optional, defaults to 14
-        "font_color": "000000", // optional, RRGGBB format, defaults to 000000 (black)
-      }
-    },
-    // Example for a checkbox. TARGET THE SQUARE for the entry bounding box, NOT THE TEXT
-    {
-      "page_number": 2,
-      "description": "Checkbox that should be checked if the user is over 18",
-      "entry_bounding_box": [140, 525, 155, 540],  // Small box over checkbox square
-      "field_label": "Yes",
-      "label_bounding_box": [100, 525, 132, 540],  // Box containing "Yes" text
-      // Use "X" to check a checkbox.
-      "entry_text": {
-        "text": "X",
-      }
-    }
-    // additional form field entries
-  ]
-}
-```
-
-Create validation images by running this script from this file's directory for each page:
-`python scripts/create_validation_image.py <page_number> <path_to_fields.json> <input_image_path> <output_image_path>
-
-The validation images will have red rectangles where text should be entered, and blue rectangles covering label text.
-
-### Step 3: Validate Bounding Boxes (REQUIRED)
-#### Automated intersection check
-- Verify that none of bounding boxes intersect and that the entry bounding boxes are tall enough by checking the fields.json file with the `check_bounding_boxes.py` script (run from this file's directory):
-`python scripts/check_bounding_boxes.py <JSON file>`
-
-If there are errors, reanalyze the relevant fields, adjust the bounding boxes, and iterate until there are no remaining errors. Remember: label (blue) bounding boxes should contain text labels, entry (red) boxes should not.
-
-#### Manual image inspection
-**CRITICAL: Do not proceed without visually inspecting validation images**
-- Red rectangles must ONLY cover input areas
-- Red rectangles MUST NOT contain any text
-- Blue rectangles should contain label text
-- For checkboxes:
-  - Red rectangle MUST be centered on the checkbox square
-  - Blue rectangle should cover the text label for the checkbox
-
-- If any rectangles look wrong, fix fields.json, regenerate the validation images, and verify again. Repeat this process until the bounding boxes are fully accurate.
-
-
-### Step 4: Add annotations to the PDF
-Run this script from this file's directory to create a filled-out PDF using the information in fields.json:
-`python scripts/fill_pdf_form_with_annotations.py <input_pdf_path> <path_to_fields.json> <output_pdf_path>

-## Reading and analyzing content
-
-### Text extraction
-To read the text contents of a presentation, convert the document to markdown:
-
-```bash
-# Convert document to markdown
-python -m markitdown path-to-file.pptx
-```
-
-### Raw XML access
-Raw XML access is required for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. For any of these features, unpack a presentation and read its raw XML contents.
-
-#### Unpacking a file
-`python ooxml/scripts/unpack.py <office_file> <output_dir>`
-
-**Note**: The unpack.py script is located at `skills/pptx/ooxml/scripts/unpack.py` relative to the project root. If the script doesn't exist at this path, use `find . -name "unpack.py"` to locate it.
-
-#### Key file structures
-* `ppt/presentation.xml` - Main presentation metadata and slide references
-* `ppt/slides/slide{N}.xml` - Individual slide contents (slide1.xml, slide2.xml, etc.)
-* `ppt/notesSlides/notesSlide{N}.xml` - Speaker notes for each slide
-* `ppt/comments/modernComment_*.xml` - Comments for specific slides
-* `ppt/slideLayouts/` - Layout templates for slides
-* `ppt/slideMasters/` - Master slide templates
-* `ppt/theme/` - Theme and styling information
-* `ppt/media/` - Images and other media files
-
-#### Typography and color extraction
-**When given an example design to emulate**: Always analyze the presentation's typography and colors first using the methods below:
-1. **Read theme file**: Check `ppt/theme/theme1.xml` for colors (`<a:clrScheme>`) and fonts (`<a:fontScheme>`)
-2. **Sample slide content**: Examine `ppt/slides/slide1.xml` for actual font usage (`<a:rPr>`) and colors
-3. **Search for patterns**: Use grep to find color (`<a:solidFill>`, `<a:srgbClr>`) and font references across all XML files
-
-## Creating a new PowerPoint presentation **without a template**
-
-When creating a new PowerPoint presentation from scratch, use the **html2pptx** workflow to convert HTML slides to PowerPoint with accurate positioning.
-
-### Design Principles
-
-**CRITICAL**: Before creating any presentation, analyze the content and choose appropriate design elements:
-1. **Consider the subject matter**: What is this presentation about? What tone, industry, or mood does it suggest?
-2. **Check for branding**: If the user mentions a company/organization, consider their brand colors and identity
-3. **Match palette to content**: Select colors that reflect the subject
-4. **State your approach**: Explain your design choices before writing code
-
-**Requirements**:
-- ✅ State your content-informed design approach BEFORE writing code
-- ✅ Use web-safe fonts only: Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact
-- ✅ Create clear visual hierarchy through size, weight, and color
-- ✅ Ensure readability: strong contrast, appropriately sized text, clean alignment
-- ✅ Be consistent: repeat patterns, spacing, and visual language across slides
-
-#### Color Palette Selection
-
-**Choosing colors creatively**:
-- **Think beyond defaults**: What colors genuinely match this specific topic? Avoid autopilot choices.
-- **Consider multiple angles**: Topic, industry, mood, energy level, target audience, brand identity (if mentioned)
-- **Be adventurous**: Try unexpected combinations - a healthcare presentation doesn't have to be green, finance doesn't have to be navy
-- **Build your palette**: Pick 3-5 colors that work together (dominant colors + supporting tones + accent)
-- **Ensure contrast**: Text must be clearly readable on backgrounds
-
-**Example color palettes** (use these to spark creativity - choose one, adapt it, or create your own):
-

-
-#### Visual Details Options
-
-**Geometric Patterns**:
-- Diagonal section dividers instead of horizontal
-- Asymmetric column widths (30/70, 40/60, 25/75)
-- Rotated text headers at 90° or 270°
-- Circular/hexagonal frames for images
-- Triangular accent shapes in corners
-- Overlapping shapes for depth
-
-**Border & Frame Treatments**:
-- Thick single-color borders (10-20pt) on one side only
-- Double-line borders with contrasting colors
-- Corner brackets instead of full frames
-- L-shaped borders (top+left or bottom+right)
-- Underline accents beneath headers (3-5pt thick)
-
-**Typography Treatments**:
-- Extreme size contrast (72pt headlines vs 11pt body)
-- All-caps headers with wide letter spacing
-- Numbered sections in oversized display type
-- Monospace (Courier New) for data/stats/technical content
-- Condensed fonts (Arial Narrow) for dense information
-- Outlined text for emphasis
-
-**Chart & Data Styling**:
-- Monochrome charts with single accent color for key data
-- Horizontal bar charts instead of vertical
-- Dot plots instead of bar charts
-- Minimal gridlines or none at all
-- Data labels directly on elements (no legends)
-- Oversized numbers for key metrics
-
-**Layout Innovations**:
-- Full-bleed images with text overlays
-- Sidebar column (20-30% width) for navigation/context
-- Modular grid systems (3×3, 4×4 blocks)
-- Z-pattern or F-pattern content flow
-- Floating text boxes over colored shapes
-- Magazine-style multi-column layouts
-
-**Background Treatments**:
-- Solid color blocks occupying 40-60% of slide
-- Gradient fills (vertical or diagonal only)
-- Split backgrounds (two colors, diagonal or vertical)
-- Edge-to-edge color bands
-- Negative space as a design element
-
-### Layout Tips
-**For slides with charts or tables:**
-- **Two-column layout (PREFERRED)**: Use a header spanning the full width, then two columns below - text/bullets in one column and the featured content in the other. This provides better balance and makes charts/tables more readable. Use flexbox with unequal column widths (e.g., 40%/60% split) to optimize space for each content type.
-- **Full-slide layout**: Let the featured content (chart/table) take up the entire slide for maximum impact and readability
-- **NEVER vertically stack**: Do not place charts/tables below text in a single column - this causes poor readability and layout issues
-
-### Workflow
-1. **MANDATORY - READ ENTIRE FILE**: Read [`html2pptx.md`](html2pptx.md) completely from start to finish. **NEVER set any range limits when reading this file.** Read the full file content for detailed syntax, critical formatting rules, and best practices before proceeding with presentation creation.
-2. Create an HTML file for each slide with proper dimensions (e.g., 720pt × 405pt for 16:9)
-   - Use `<p>`, `<h1>`-`<h6>`, `<ul>`, `<ol>` for all text content
-   - Use `class="placeholder"` for areas where charts/tables will be added (render with gray background for visibility)
-   - **CRITICAL**: Rasterize gradients and icons as PNG images FIRST using Sharp, then reference in HTML
-   - **LAYOUT**: For slides with charts/tables/images, use either full-slide layout or two-column layout for better readability
-3. Create and run a JavaScript file using the [`html2pptx.js`](scripts/html2pptx.js) library to convert HTML slides to PowerPoint and save the presentation
-   - Use the `html2pptx()` function to process each HTML file
-   - Add charts and tables to placeholder areas using PptxGenJS API
-   - Save the presentation using `pptx.writeFile()`
-4. **Visual validation**: Generate thumbnails and inspect for layout issues
-   - Create thumbnail grid: `python scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4`
-   - Read and carefully examine the thumbnail image for:
-     - **Text cutoff**: Text being cut off by header bars, shapes, or slide edges
-     - **Text overlap**: Text overlapping with other text or shapes
-     - **Positioning issues**: Content too close to slide boundaries or other elements
-     - **Contrast issues**: Insufficient contrast between text and backgrounds
-   - If issues found, adjust HTML margins/spacing/colors and regenerate the presentation
-   - Repeat until all slides are visually correct
-
-## Editing an existing PowerPoint presentation
-
-To edit slides in an existing PowerPoint presentation, work with the raw Office Open XML (OOXML) format. This involves unpacking the .pptx file, editing the XML content, and repacking it.
-
-### Workflow
-1. **MANDATORY - READ ENTIRE FILE**: Read [`ooxml.md`](ooxml.md) (~500 lines) completely from start to finish.  **NEVER set any range limits when reading this file.**  Read the full file content for detailed guidance on OOXML structure and editing workflows before any presentation editing.
-2. Unpack the presentation: `python ooxml/scripts/unpack.py <office_file> <output_dir>`
-3. Edit the XML files (primarily `ppt/slides/slide{N}.xml` and related files)
-4. **CRITICAL**: Validate immediately after each edit and fix any validation errors before proceeding: `python ooxml/scripts/validate.py <dir> --original <file>`
-5. Pack the final presentation: `python ooxml/scripts/pack.py <input_directory> <office_file>`
-
-## Creating a new PowerPoint presentation **using a template**
-
-To create a presentation that follows an existing template's design, duplicate and re-arrange template slides before replacing placeholder context.
-
-### Workflow
-1. **Extract template text AND create visual thumbnail grid**:
-   * Extract text: `python -m markitdown template.pptx > template-content.md`
-   * Read `template-content.md`: Read the entire file to understand the contents of the template presentation. **NEVER set any range limits when reading this file.**
-   * Create thumbnail grids: `python scripts/thumbnail.py template.pptx`
-   * See [Creating Thumbnail Grids](#creating-thumbnail-grids) section for more details
-
-2. **Analyze template and save inventory to a file**:
-   * **Visual Analysis**: Review thumbnail grid(s) to understand slide layouts, design patterns, and visual structure
-   * Create and save a template inventory file at `template-inventory.md` containing:
-     ```markdown
-     # Template Inventory Analysis
-     **Total Slides: [count]**
-     **IMPORTANT: Slides are 0-indexed (first slide = 0, last slide = count-1)**
-
-     ## [Category Name]
-     - Slide 0: [Layout code if available] - Description/purpose
-     - Slide 1: [Layout code] - Description/purpose
-     - Slide 2: [Layout code] - Description/purpose
-     [... EVERY slide must be listed individually with its index ...]
-     ```
-   * **Using the thumbnail grid**: Reference the visual thumbnails to identify:
-     - Layout patterns (title slides, content layouts, section dividers)
-     - Image placeholder locations and counts
-     - Design consistency across slide groups
-     - Visual hierarchy and structure
-   * This inventory file is REQUIRED for selecting appropriate templates in the next step
-
-3. **Create presentation outline based on template inventory**:
-   * Review available templates from step 2.
-   * Choose an intro or title template for the first slide. This should be one of the first templates.
-   * Choose safe, text-based layouts for the other slides.
-   * **CRITICAL: Match layout structure to actual content**:
-     - Single-column layouts: Use for unified narrative or single topic
-     - Two-column layouts: Use ONLY when there are exactly 2 distinct items/concepts
-     - Three-column layouts: Use ONLY when there are exactly 3 distinct items/concepts
-     - Image + text layouts: Use ONLY when actual images are available to insert
-     - Quote layouts: Use ONLY for actual quotes from people (with attribution), never for emphasis
-     - Never use layouts with more placeholders than available content
-     - If there are 2 items, don't force them into a 3-column layout
-     - If there are 4+ items, consider breaking into multiple slides or using a list format
-   * Count actual content pieces BEFORE selecting the layout
-   * Verify each placeholder in the chosen layout will be filled with meaningful content
-   * Select one option representing the **best** layout for each content section.
-   * Save `outline.md` with content AND template mapping that leverages available designs
-   * Example template mapping:
-      ```
-      # Template slides to use (0-based indexing)
-      # WARNING: Verify indices are within range! Template with 73 slides has indices 0-72
-      # Mapping: slide numbers from outline -> template slide indices
-      template_mapping = [
-          0,   # Use slide 0 (Title/Cover)
-          34,  # Use slide 34 (B1: Title and body)
-          34,  # Use slide 34 again (duplicate for second B1)
-          50,  # Use slide 50 (E1: Quote)
-          54,  # Use slide 54 (F2: Closing + Text)
-      ]
-      ```
-
-4. **Duplicate, reorder, and delete slides using `rearrange.py`**:
-   * Use the `scripts/rearrange.py` script to create a new presentation with slides in the desired order:
-     ```bash
-     python scripts/rearrange.py template.pptx working.pptx 0,34,34,50,52
-     ```
-   * The script handles duplicating repeated slides, deleting unused slides, and reordering automatically
-   * Slide indices are 0-based (first slide is 0, second is 1, etc.)
-   * The same slide index can appear multiple times to duplicate that slide
-
-5. **Extract ALL text using the `inventory.py` script**:
-   * **Run inventory extraction**:
-     ```bash
-     python scripts/inventory.py working.pptx text-inventory.json
-     ```
-   * **Read text-inventory.json**: Read the entire text-inventory.json file to understand all shapes and their properties. **NEVER set any range limits when reading this file.**
-
-   * The inventory JSON structure:
-      ```json
-        {
-          "slide-0": {
-            "shape-0": {
-              "placeholder_type": "TITLE",  // or null for non-placeholders
-              "left": 1.5,                  // position in inches
-              "top": 2.0,
-              "width": 7.5,
-              "height": 1.2,
-              "paragraphs": [
-                {
-                  "text": "Paragraph text",
-                  // Optional properties (only included when non-default):
-                  "bullet": true,           // explicit bullet detected
-                  "level": 0,               // only included when bullet is true
-                  "alignment": "CENTER",    // CENTER, RIGHT (not LEFT)
-                  "space_before": 10.0,     // space before paragraph in points
-                  "space_after": 6.0,       // space after paragraph in points
-                  "line_spacing": 22.4,     // line spacing in points
-                  "font_name": "Arial",     // from first run
-                  "font_size": 14.0,        // in points
-                  "bold": true,
-                  "italic": false,
-                  "underline": false,
-                  "color": "FF0000"         // RGB color
-                }
-              ]
-            }
-          }
-        }
-      ```
-
-   * Key features:
-     - **Slides**: Named as "slide-0", "slide-1", etc.
-     - **Shapes**: Ordered by visual position (top-to-bottom, left-to-right) as "shape-0", "shape-1", etc.
-     - **Placeholder types**: TITLE, CENTER_TITLE, SUBTITLE, BODY, OBJECT, or null
-     - **Default font size**: `default_font_size` in points extracted from layout placeholders (when available)
-     - **Slide numbers are filtered**: Shapes with SLIDE_NUMBER placeholder type are automatically excluded from inventory
-     - **Bullets**: When `bullet: true`, `level` is always included (even if 0)
-     - **Spacing**: `space_before`, `space_after`, and `line_spacing` in points (only included when set)
-     - **Colors**: `color` for RGB (e.g., "FF0000"), `theme_color` for theme colors (e.g., "DARK_1")
-     - **Properties**: Only non-default values are included in the output
-
-6. **Generate replacement text and save the data to a JSON file**
-   Based on the text inventory from the previous step:
-   - **CRITICAL**: First verify which shapes exist in the inventory - only reference shapes that are actually present
-   - **VALIDATION**: The replace.py script will validate that all shapes in the replacement JSON exist in the inventory
-     - If a non-existent shape is referenced, an error will show available shapes
-     - If a non-existent slide is referenced, an error will indicate the slide doesn't exist
-     - All validation errors are shown at once before the script exits
-   - **IMPORTANT**: The replace.py script uses inventory.py internally to identify ALL text shapes
-   - **AUTOMATIC CLEARING**: ALL text shapes from the inventory will be cleared unless you provide "paragraphs" for them
-   - Add a "paragraphs" field to shapes that need content (not "replacement_paragraphs")
-   - Shapes without "paragraphs" in the replacement JSON will have their text cleared automatically
-   - Paragraphs with bullets will be automatically left aligned. Don't set the `alignment` property on when `"bullet": true`
-   - Generate appropriate replacement content for placeholder text
-   - Use shape size to determine appropriate content length
-   - **CRITICAL**: Include paragraph properties from the original inventory - don't just provide text
-   - **IMPORTANT**: When bullet: true, do NOT include bullet symbols (•, -, *) in text - they are added automatically
-   - **ESSENTIAL FORMATTING RULES**:
-     - Headers/titles should typically have `"bold": true`
-     - List items should have `"bullet": true, "level": 0` (level is required when bullet is true)
-     - Preserve any alignment properties (e.g., `"alignment": "CENTER"` for centered text)
-     - Include font properties when different from default (e.g., `"font_size": 14.0`, `"font_name": "Lora"`)
-     - Colors: Use `"color": "FF0000"` for RGB or `"theme_color": "DARK_1"` for theme colors
-     - The replacement script expects **properly formatted paragraphs**, not just text strings
-     - **Overlapping shapes**: Prefer shapes with larger default_font_size or more appropriate placeholder_type
-   - Save the updated inventory with replacements to `replacement-text.json`
-   - **WARNING**: Different template layouts have different shape counts - always check the actual inventory before creating replacements
-
-   Example paragraphs field showing proper formatting:
-   ```json
-   "paragraphs": [
-     {
-       "text": "New presentation title text",
-       "alignment": "CENTER",
-       "bold": true
-     },
-     {
-       "text": "Section Header",
-       "bold": true
-     },
-     {
-       "text": "First bullet point without bullet symbol",
-       "bullet": true,
-       "level": 0
-     },
-     {
-       "text": "Red colored text",
-       "color": "FF0000"
-     },
-     {
-       "text": "Theme colored text",
-       "theme_color": "DARK_1"
-     },
-     {
-       "text": "Regular paragraph text without special formatting"
-     }
-   ]
-   ```
-
-   **Shapes not listed in the replacement JSON are automatically cleared**:
-   ```json
-   {
-     "slide-0": {
-       "shape-0": {
-         "paragraphs": [...] // This shape gets new text
-       }
-       // shape-1 and shape-2 from inventory will be cleared automatically
-     }
-   }
-   ```
-
-   **Common formatting patterns for presentations**:
-   - Title slides: Bold text, sometimes centered
-   - Section headers within slides: Bold text
-   - Bullet lists: Each item needs `"bullet": true, "level": 0`
-   - Body text: Usually no special properties needed
-   - Quotes: May have special alignment or font properties
-
-7. **Apply replacements using the `replace.py` script**
-   ```bash
-   python scripts/replace.py working.pptx replacement-text.json output.pptx
-   ```
-
-   The script will:
-   - First extract the inventory of ALL text shapes using functions from inventory.py
-   - Validate that all shapes in the replacement JSON exist in the inventory
-   - Clear text from ALL shapes identified in the inventory
-   - Apply new text only to shapes with "paragraphs" defined in the replacement JSON
-   - Preserve formatting by applying paragraph properties from the JSON
-   - Handle bullets, alignment, font properties, and colors automatically
-   - Save the updated presentation
-
-   Example validation errors:
-   ```
-   ERROR: Invalid shapes in replacement JSON:
-     - Shape 'shape-99' not found on 'slide-0'. Available shapes: shape-0, shape-1, shape-4
-     - Slide 'slide-999' not found in inventory
-   ```
-
-   ```
-   ERROR: Replacement text made overflow worse in these shapes:
-     - slide-0/shape-2: overflow worsened by 1.25" (was 0.00", now 1.25")
-   ```
-
-## Creating Thumbnail Grids
-
-To create visual thumbnail grids of PowerPoint slides for quick analysis and reference:
-
-```bash
-python scripts/thumbnail.py template.pptx [output_prefix]
-```
-
-**Features**:
-- Creates: `thumbnails.jpg` (or `thumbnails-1.jpg`, `thumbnails-2.jpg`, etc. for large decks)
-- Default: 5 columns, max 30 slides per grid (5×6)
-- Custom prefix: `python scripts/thumbnail.py template.pptx my-grid`
-  - Note: The output prefix should include the path if you want output in a specific directory (e.g., `workspace/my-grid`)
-- Adjust columns: `--cols 4` (range: 3-6, affects slides per grid)
-- Grid limits: 3 cols = 12 slides/grid, 4 cols = 20, 5 cols = 30, 6 cols = 42
-- Slides are zero-indexed (Slide 0, Slide 1, etc.)
-
-**Use cases**:
-- Template analysis: Quickly understand slide layouts and design patterns
-- Content review: Visual overview of entire presentation
-- Navigation reference: Find specific slides by their visual appearance
-- Quality check: Verify all slides are properly formatted
-
-**Examples**:
-```bash
-# Basic usage
-python scripts/thumbnail.py presentation.pptx
-
-# Combine options: custom name, columns
-python scripts/thumbnail.py template.pptx analysis --cols 4
-```
-
-## Converting Slides to Images
-
-To visually analyze PowerPoint slides, convert them to images using a two-step process:
-
-1. **Convert PPTX to PDF**:
-   ```bash
-   soffice --headless --convert-to pdf template.pptx
-   ```
-
-2. **Convert PDF pages to JPEG images**:
-   ```bash
-   pdftoppm -jpeg -r 150 template.pdf slide
-   ```
-   This creates files like `slide-1.jpg`, `slide-2.jpg`, etc.
-
-Options:
-- `-r 150`: Sets resolution to 150 DPI (adjust for quality/size balance)
-- `-jpeg`: Output JPEG format (use `-png` for PNG if preferred)
-- `-f N`: First page to convert (e.g., `-f 2` starts from page 2)
-- `-l N`: Last page to convert (e.g., `-l 5` stops at page 5)
-- `slide`: Prefix for output files
-
-Example for specific range:
-```bash
-pdftoppm -jpeg -r 150 -f 2 -l 5 template.pdf slide  # Converts only pages 2-5
-```
-
-## Code Style Guidelines
-**IMPORTANT**: When generating code for PPTX operations:
-- Write concise code
-- Avoid verbose variable names and redundant operations
-- Avoid unnecessary print statements
-
-## Dependencies
-
-Required dependencies (should already be installed):
-
-- **markitdown**: `pip install "markitdown[pptx]"` (for text extraction from presentations)
-- **pptxgenjs**: `npm install -g pptxgenjs` (for creating presentations via html2pptx)
-- **playwright**: `npm install -g playwright` (for HTML rendering in html2pptx)
-- **react-icons**: `npm install -g react-icons react react-dom` (for icons)
-- **sharp**: `npm install -g sharp` (for SVG rasterization and image processing)
-- **LibreOffice**: `sudo apt-get install libreoffice` (for PDF conversion)
-- **Poppler**: `sudo apt-get install poppler-utils` (for pdftoppm to convert PDF to images)
-- **defusedxml**: `pip install defusedxml` (for secure XML parsing)

-# HTML to PowerPoint Guide
-
-Convert HTML slides to PowerPoint presentations with accurate positioning using the `html2pptx.js` library.
-

----
-
-## Creating HTML Slides
-
-Every HTML slide must include proper body dimensions:
-
-### Layout Dimensions
-
-- **16:9** (default): `width: 720pt; height: 405pt`
-- **4:3**: `width: 720pt; height: 540pt`
-- **16:10**: `width: 720pt; height: 450pt`
-
-### Supported Elements
-
-- `<p>`, `<h1>`-`<h6>` - Text with styling
-- `<ul>`, `<ol>` - Lists (never use manual bullets •, -, *)
-- `<b>`, `<strong>` - Bold text (inline formatting)
-- `<i>`, `<em>` - Italic text (inline formatting)
-- `<u>` - Underlined text (inline formatting)
-- `<span>` - Inline formatting with CSS styles (bold, italic, underline, color)
-- `<br>` - Line breaks
-- `<div>` with bg/border - Becomes shape
-- `<img>` - Images
-- `class="placeholder"` - Reserved space for charts (returns `{ id, x, y, w, h }`)
-
-### Critical Text Rules
-
-**ALL text MUST be inside `<p>`, `<h1>`-`<h6>`, `<ul>`, or `<ol>` tags:**
-- ✅ Correct: `<div><p>Text here</p></div>`
-- ❌ Wrong: `<div>Text here</div>` - **Text will NOT appear in PowerPoint**
-- ❌ Wrong: `<span>Text</span>` - **Text will NOT appear in PowerPoint**
-- Text in `<div>` or `<span>` without a text tag will be silently ignored
-
-**NEVER use manual bullet symbols (•, -, *, etc.)** - Use `<ul>` or `<ol>` lists instead
-
-**ONLY use web-safe fonts that are universally available:**
-- ✅ Web-safe fonts: `Arial`, `Helvetica`, `Times New Roman`, `Georgia`, `Courier New`, `Verdana`, `Tahoma`, `Trebuchet MS`, `Impact`, `Comic Sans MS`
-- ❌ Wrong: `'Segoe UI'`, `'SF Pro'`, `'Roboto'`, custom fonts - **Might cause rendering issues**
-
-### Styling
-
-- Use `display: flex` on body to prevent margin collapse from breaking overflow validation
-- Use `margin` for spacing (padding included in size)
-- Inline formatting: Use `<b>`, `<i>`, `<u>` tags OR `<span>` with CSS styles
-  - `<span>` supports: `font-weight: bold`, `font-style: italic`, `text-decoration: underline`, `color: #rrggbb`
-  - `<span>` does NOT support: `margin`, `padding` (not supported in PowerPoint text runs)
-  - Example: `<span style="font-weight: bold; color: #667eea;">Bold blue text</span>`
-- Flexbox works - positions calculated from rendered layout
-- Use hex colors with `#` prefix in CSS
-- **Text alignment**: Use CSS `text-align` (`center`, `right`, etc.) when needed as a hint to PptxGenJS for text formatting if text lengths are slightly off
-
-### Shape Styling (DIV elements only)
-
-**IMPORTANT: Backgrounds, borders, and shadows only work on `<div>` elements, NOT on text elements (`<p>`, `<h1>`-`<h6>`, `<ul>`, `<ol>`)**
-
-- **Backgrounds**: CSS `background` or `background-color` on `<div>` elements only
-  - Example: `<div style="background: #f0f0f0;">` - Creates a shape with background
-- **Borders**: CSS `border` on `<div>` elements converts to PowerPoint shape borders
-  - Supports uniform borders: `border: 2px solid #333333`
-  - Supports partial borders: `border-left`, `border-right`, `border-top`, `border-bottom` (rendered as line shapes)
-  - Example: `<div style="border-left: 8pt solid #E76F51;">`
-- **Border radius**: CSS `border-radius` on `<div>` elements for rounded corners
-  - `border-radius: 50%` or higher creates circular shape
-  - Percentages <50% calculated relative to shape's smaller dimension
-  - Supports px and pt units (e.g., `border-radius: 8pt;`, `border-radius: 12px;`)
-  - Example: `<div style="border-radius: 25%;">` on 100x200px box = 25% of 100px = 25px radius
-- **Box shadows**: CSS `box-shadow` on `<div>` elements converts to PowerPoint shadows
-  - Supports outer shadows only (inset shadows are ignored to prevent corruption)
-  - Example: `<div style="box-shadow: 2px 2px 8px rgba(0, 0, 0, 0.3);">`
-  - Note: Inset/inner shadows are not supported by PowerPoint and will be skipped
-
-### Icons & Gradients
-
-- **CRITICAL: Never use CSS gradients (`linear-gradient`, `radial-gradient`)** - They don't convert to PowerPoint
-- **ALWAYS create gradient/icon PNGs FIRST using Sharp, then reference in HTML**
-- For gradients: Rasterize SVG to PNG background images
-- For icons: Rasterize react-icons SVG to PNG images
-- All visual effects must be pre-rendered as raster images before HTML rendering
-
-**Rasterizing Icons with Sharp:**
-
-```javascript
-const React = require('react');
-const ReactDOMServer = require('react-dom/server');
-const sharp = require('sharp');
-const { FaHome } = require('react-icons/fa');
-
-async function rasterizeIconPng(IconComponent, color, size = "256", filename) {
-  const svgString = ReactDOMServer.renderToStaticMarkup(
-    React.createElement(IconComponent, { color: `#${color}`, size: size })
-  );
-
-  // Convert SVG to PNG using Sharp
-  await sharp(Buffer.from(svgString))
-    .png()
-    .toFile(filename);
-
-  return filename;
-}
-
-// Usage: Rasterize icon before using in HTML
-const iconPath = await rasterizeIconPng(FaHome, "4472c4", "256", "home-icon.png");
-// Then reference in HTML: <img src="home-icon.png" style="width: 40pt; height: 40pt;">
-```
-
-**Rasterizing Gradients with Sharp:**
-
-```javascript
-const sharp = require('sharp');
-
-async function createGradientBackground(filename) {
-  const svg = `<svg xmlns="http://www.w3.org/2000/svg" width="1000" height="562.5">
-    <defs>
-      <linearGradient id="g" x1="0%" y1="0%" x2="100%" y2="100%">
-        <stop offset="0%" style="stop-color:#COLOR1"/>
-        <stop offset="100%" style="stop-color:#COLOR2"/>
-      </linearGradient>
-    </defs>
-    <rect width="100%" height="100%" fill="url(#g)"/>
-  </svg>`;
-
-  await sharp(Buffer.from(svg))
-    .png()
-    .toFile(filename);
-
-  return filename;
-}
-
-// Usage: Create gradient background before HTML
-const bgPath = await createGradientBackground("gradient-bg.png");
-// Then in HTML: <body style="background-image: url('gradient-bg.png');">
-```
-
-### Example
-
-```html
-<!DOCTYPE html>
-<html>
-<head>
-<style>
-html { background: #ffffff; }
-body {
-  width: 720pt; height: 405pt; margin: 0; padding: 0;
-  background: #f5f5f5; font-family: Arial, sans-serif;
-  display: flex;
-}
-.content { margin: 30pt; padding: 40pt; background: #ffffff; border-radius: 8pt; }
-h1 { color: #2d3748; font-size: 32pt; }
-.box {
-  background: #70ad47; padding: 20pt; border: 3px solid #5a8f37;
-  border-radius: 12pt; box-shadow: 3px 3px 10px rgba(0, 0, 0, 0.25);
-}
-</style>
-</head>
-<body>
-<div class="content">
-  <h1>Recipe Title</h1>
-  <ul>
-    <li><b>Item:</b> Description</li>
-  </ul>
-  <p>Text with <b>bold</b>, <i>italic</i>, <u>underline</u>.</p>
-  <div id="chart" class="placeholder" style="width: 350pt; height: 200pt;"></div>
-
-  <!-- Text MUST be in <p> tags -->
-  <div class="box">
-    <p>5</p>
-  </div>
-</div>
-</body>
-</html>

-## Using the html2pptx Library
-
-### Dependencies
-
-These libraries have been globally installed and are available to use:
-- `pptxgenjs`
-- `playwright`
-- `sharp`
-
-### Basic Usage
-
-```javascript
-const pptxgen = require('pptxgenjs');
-const html2pptx = require('./html2pptx');
-
-const pptx = new pptxgen();
-pptx.layout = 'LAYOUT_16x9';  // Must match HTML body dimensions
-
-const { slide, placeholders } = await html2pptx('slide1.html', pptx);
-
-// Add chart to placeholder area
-if (placeholders.length > 0) {
-    slide.addChart(pptx.charts.LINE, chartData, placeholders[0]);
-}
-
-await pptx.writeFile('output.pptx');
-```
-
-### API Reference
-
-#### Function Signature
-```javascript
-await html2pptx(htmlFile, pres, options)
-```
-
-#### Parameters
-- `htmlFile` (string): Path to HTML file (absolute or relative)
-- `pres` (pptxgen): PptxGenJS presentation instance with layout already set
-- `options` (object, optional):
-  - `tmpDir` (string): Temporary directory for generated files (default: `process.env.TMPDIR || '/tmp'`)
-  - `slide` (object): Existing slide to reuse (default: creates new slide)
-
-#### Returns
-```javascript
-{
-    slide: pptxgenSlide,           // The created/updated slide
-    placeholders: [                 // Array of placeholder positions
-        { id: string, x: number, y: number, w: number, h: number },
-        ...
-    ]
-}
-```
-
-### Validation
-
-The library automatically validates and collects all errors before throwing:
-
-1. **HTML dimensions must match presentation layout** - Reports dimension mismatches
-2. **Content must not overflow body** - Reports overflow with exact measurements
-3. **CSS gradients** - Reports unsupported gradient usage
-4. **Text element styling** - Reports backgrounds/borders/shadows on text elements (only allowed on divs)
-
-**All validation errors are collected and reported together** in a single error message, allowing you to fix all issues at once instead of one at a time.
-
-### Working with Placeholders
-
-```javascript
-const { slide, placeholders } = await html2pptx('slide.html', pptx);
-
-// Use first placeholder
-slide.addChart(pptx.charts.BAR, data, placeholders[0]);
-
-// Find by ID
-const chartArea = placeholders.find(p => p.id === 'chart-area');
-slide.addChart(pptx.charts.LINE, data, chartArea);
-```
-
-### Complete Example
-
-```javascript
-const pptxgen = require('pptxgenjs');
-const html2pptx = require('./html2pptx');
-
-async function createPresentation() {
-    const pptx = new pptxgen();
-    pptx.layout = 'LAYOUT_16x9';
-    pptx.author = 'Your Name';
-    pptx.title = 'My Presentation';
-
-    // Slide 1: Title
-    const { slide: slide1 } = await html2pptx('slides/title.html', pptx);
-
-    // Slide 2: Content with chart
-    const { slide: slide2, placeholders } = await html2pptx('slides/data.html', pptx);
-
-    const chartData = [{
-        name: 'Sales',
-        labels: ['Q1', 'Q2', 'Q3', 'Q4'],
-        values: [4500, 5500, 6200, 7100]
-    }];
-
-    slide2.addChart(pptx.charts.BAR, chartData, {
-        ...placeholders[0],
-        showTitle: true,
-        title: 'Quarterly Sales',
-        showCatAxisTitle: true,
-        catAxisTitle: 'Quarter',
-        showValAxisTitle: true,
-        valAxisTitle: 'Sales ($000s)'
-    });
-
-    // Save
-    await pptx.writeFile({ fileName: 'presentation.pptx' });
-    console.log('Presentation created successfully!');
-}
-
-createPresentation().catch(console.error);
-```
-
-## Using PptxGenJS
-
-After converting HTML to slides with `html2pptx`, you'll use PptxGenJS to add dynamic content like charts, images, and additional elements.
-
-### ⚠️ Critical Rules
-
-#### Colors
-- **NEVER use `#` prefix** with hex colors in PptxGenJS - causes file corruption
-- ✅ Correct: `color: "FF0000"`, `fill: { color: "0066CC" }`
-- ❌ Wrong: `color: "#FF0000"` (breaks document)
-
-### Adding Images
-
-Always calculate aspect ratios from actual image dimensions:
-
-```javascript
-// Get image dimensions: identify image.png | grep -o '[0-9]* x [0-9]*'
-const imgWidth = 1860, imgHeight = 1519;  // From actual file
-const aspectRatio = imgWidth / imgHeight;
-
-const h = 3;  // Max height
-const w = h * aspectRatio;
-const x = (10 - w) / 2;  // Center on 16:9 slide
-
-slide.addImage({ path: "chart.png", x, y: 1.5, w, h });
-```
-
-### Adding Text
-
-```javascript
-// Rich text with formatting
-slide.addText([
-    { text: "Bold ", options: { bold: true } },
-    { text: "Italic ", options: { italic: true } },
-    { text: "Normal" }
-], {
-    x: 1, y: 2, w: 8, h: 1
-});
-```
-
-### Adding Shapes
-
-```javascript
-// Rectangle
-slide.addShape(pptx.shapes.RECTANGLE, {
-    x: 1, y: 1, w: 3, h: 2,
-    fill: { color: "4472C4" },
-    line: { color: "000000", width: 2 }
-});
-
-// Circle
-slide.addShape(pptx.shapes.OVAL, {
-    x: 5, y: 1, w: 2, h: 2,
-    fill: { color: "ED7D31" }
-});
-
-// Rounded rectangle
-slide.addShape(pptx.shapes.ROUNDED_RECTANGLE, {
-    x: 1, y: 4, w: 3, h: 1.5,
-    fill: { color: "70AD47" },
-    rectRadius: 0.2
-});
-```
-
-### Adding Charts
-
-**Required for most charts:** Axis labels using `catAxisTitle` (category) and `valAxisTitle` (value).
-
-**Chart Data Format:**
-- Use **single series with all labels** for simple bar/line charts
-- Each series creates a separate legend entry
-- Labels array defines X-axis values
-
-**Time Series Data - Choose Correct Granularity:**
-- **< 30 days**: Use daily grouping (e.g., "10-01", "10-02") - avoid monthly aggregation that creates single-point charts
-- **30-365 days**: Use monthly grouping (e.g., "2024-01", "2024-02")
-- **> 365 days**: Use yearly grouping (e.g., "2023", "2024")
-- **Validate**: Charts with only 1 data point likely indicate incorrect aggregation for the time period
-
-```javascript
-const { slide, placeholders } = await html2pptx('slide.html', pptx);
-
-// CORRECT: Single series with all labels
-slide.addChart(pptx.charts.BAR, [{
-    name: "Sales 2024",
-    labels: ["Q1", "Q2", "Q3", "Q4"],
-    values: [4500, 5500, 6200, 7100]
-}], {
-    ...placeholders[0],  // Use placeholder position
-    barDir: 'col',       // 'col' = vertical bars, 'bar' = horizontal
-    showTitle: true,
-    title: 'Quarterly Sales',
-    showLegend: false,   // No legend needed for single series
-    // Required axis labels
-    showCatAxisTitle: true,
-    catAxisTitle: 'Quarter',
-    showValAxisTitle: true,
-    valAxisTitle: 'Sales ($000s)',
-    // Optional: Control scaling (adjust min based on data range for better visualization)
-    valAxisMaxVal: 8000,
-    valAxisMinVal: 0,  // Use 0 for counts/amounts; for clustered data (e.g., 4500-7100), consider starting closer to min value
-    valAxisMajorUnit: 2000,  // Control y-axis label spacing to prevent crowding
-    catAxisLabelRotate: 45,  // Rotate labels if crowded
-    dataLabelPosition: 'outEnd',
-    dataLabelColor: '000000',
-    // Use single color for single-series charts
-    chartColors: ["4472C4"]  // All bars same color
-});
-```
-
-#### Scatter Chart
-
-**IMPORTANT**: Scatter chart data format is unusual - first series contains X-axis values, subsequent series contain Y-values:
-
-```javascript
-// Prepare data
-const data1 = [{ x: 10, y: 20 }, { x: 15, y: 25 }, { x: 20, y: 30 }];
-const data2 = [{ x: 12, y: 18 }, { x: 18, y: 22 }];
-
-const allXValues = [...data1.map(d => d.x), ...data2.map(d => d.x)];
-
-slide.addChart(pptx.charts.SCATTER, [
-    { name: 'X-Axis', values: allXValues },  // First series = X values
-    { name: 'Series 1', values: data1.map(d => d.y) },  // Y values only
-    { name: 'Series 2', values: data2.map(d => d.y) }   // Y values only
-], {
-    x: 1, y: 1, w: 8, h: 4,
-    lineSize: 0,  // 0 = no connecting lines
-    lineDataSymbol: 'circle',
-    lineDataSymbolSize: 6,
-    showCatAxisTitle: true,
-    catAxisTitle: 'X Axis',
-    showValAxisTitle: true,
-    valAxisTitle: 'Y Axis',
-    chartColors: ["4472C4", "ED7D31"]
-});
-```
-
-#### Line Chart
-
-```javascript
-slide.addChart(pptx.charts.LINE, [{
-    name: "Temperature",
-    labels: ["Jan", "Feb", "Mar", "Apr"],
-    values: [32, 35, 42, 55]
-}], {
-    x: 1, y: 1, w: 8, h: 4,
-    lineSize: 4,
-    lineSmooth: true,
-    // Required axis labels
-    showCatAxisTitle: true,
-    catAxisTitle: 'Month',
-    showValAxisTitle: true,
-    valAxisTitle: 'Temperature (°F)',
-    // Optional: Y-axis range (set min based on data range for better visualization)
-    valAxisMinVal: 0,     // For ranges starting at 0 (counts, percentages, etc.)
-    valAxisMaxVal: 60,
-    valAxisMajorUnit: 20,  // Control y-axis label spacing to prevent crowding (e.g., 10, 20, 25)
-    // valAxisMinVal: 30,  // PREFERRED: For data clustered in a range (e.g., 32-55 or ratings 3-5), start axis closer to min value to show variation
-    // Optional: Chart colors
-    chartColors: ["4472C4", "ED7D31", "A5A5A5"]
-});
-```
-
-#### Pie Chart (No Axis Labels Required)
-
-**CRITICAL**: Pie charts require a **single data series** with all categories in the `labels` array and corresponding values in the `values` array.
-
-```javascript
-slide.addChart(pptx.charts.PIE, [{
-    name: "Market Share",
-    labels: ["Product A", "Product B", "Other"],  // All categories in one array
-    values: [35, 45, 20]  // All values in one array
-}], {
-    x: 2, y: 1, w: 6, h: 4,
-    showPercent: true,
-    showLegend: true,
-    legendPos: 'r',  // right
-    chartColors: ["4472C4", "ED7D31", "A5A5A5"]
-});
-```
-
-#### Multiple Data Series
-
-```javascript
-slide.addChart(pptx.charts.LINE, [
-    {
-        name: "Product A",
-        labels: ["Q1", "Q2", "Q3", "Q4"],
-        values: [10, 20, 30, 40]
-    },
-    {
-        name: "Product B",
-        labels: ["Q1", "Q2", "Q3", "Q4"],
-        values: [15, 25, 20, 35]
-    }
-], {
-    x: 1, y: 1, w: 8, h: 4,
-    showCatAxisTitle: true,
-    catAxisTitle: 'Quarter',
-    showValAxisTitle: true,
-    valAxisTitle: 'Revenue ($M)'
-});
-```
-
-### Chart Colors
-
-**CRITICAL**: Use hex colors **without** the `#` prefix - including `#` causes file corruption.
-
-**Align chart colors with your chosen design palette**, ensuring sufficient contrast and distinctiveness for data visualization. Adjust colors for:
-- Strong contrast between adjacent series
-- Readability against slide backgrounds
-- Accessibility (avoid red-green only combinations)
-
-```javascript
-// Example: Ocean palette-inspired chart colors (adjusted for contrast)
-const chartColors = ["16A085", "FF6B9D", "2C3E50", "F39C12", "9B59B6"];
-
-// Single-series chart: Use one color for all bars/points
-slide.addChart(pptx.charts.BAR, [{
-    name: "Sales",
-    labels: ["Q1", "Q2", "Q3", "Q4"],
-    values: [4500, 5500, 6200, 7100]
-}], {
-    ...placeholders[0],
-    chartColors: ["16A085"],  // All bars same color
-    showLegend: false
-});
-
-// Multi-series chart: Each series gets a different color
-slide.addChart(pptx.charts.LINE, [
-    { name: "Product A", labels: ["Q1", "Q2", "Q3"], values: [10, 20, 30] },
-    { name: "Product B", labels: ["Q1", "Q2", "Q3"], values: [15, 25, 20] }
-], {
-    ...placeholders[0],
-    chartColors: ["16A085", "FF6B9D"]  // One color per series
-});
-```
-
-### Adding Tables
-
-Tables can be added with basic or advanced formatting:
-
-#### Basic Table
-
-```javascript
-slide.addTable([
-    ["Header 1", "Header 2", "Header 3"],
-    ["Row 1, Col 1", "Row 1, Col 2", "Row 1, Col 3"],
-    ["Row 2, Col 1", "Row 2, Col 2", "Row 2, Col 3"]
-], {
-    x: 0.5,
-    y: 1,
-    w: 9,
-    h: 3,
-    border: { pt: 1, color: "999999" },
-    fill: { color: "F1F1F1" }
-});
-```
-
-#### Table with Custom Formatting
-

-
-### Table Options
-
-Common table options:
-- `x, y, w, h` - Position and size
-- `colW` - Array of column widths (in inches)
-- `rowH` - Array of row heights (in inches)
-- `border` - Border style: `{ pt: 1, color: "999999" }`
-- `fill` - Background color (no # prefix)
-- `align` - Text alignment: "left", "center", "right"

-# Office Open XML Technical Reference for PowerPoint
-
-**Important: Read this entire document before starting.** Critical XML schema rules and formatting requirements are covered throughout. Incorrect implementation can create invalid PPTX files that PowerPoint cannot open.
-
-## Technical Guidelines
-
-### Schema Compliance
-- **Element ordering in `<p:txBody>`**: `<a:bodyPr>`, `<a:lstStyle>`, `<a:p>`
-- **Whitespace**: Add `xml:space='preserve'` to `<a:t>` elements with leading/trailing spaces
-- **Unicode**: Escape characters in ASCII content: `"` becomes `&#8220;`
-- **Images**: Add to `ppt/media/`, reference in slide XML, set dimensions to fit slide bounds
-- **Relationships**: Update `ppt/slides/_rels/slideN.xml.rels` for each slide's resources
-- **Dirty attribute**: Add `dirty="0"` to `<a:rPr>` and `<a:endParaRPr>` elements to indicate clean state

-  <!-- Content body -->
-</p:sp>
-```
-
-## File Updates
-
-When adding content, update these files:
-
-**`ppt/_rels/presentation.xml.rels`:**
-```xml
-<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slide" Target="slides/slide1.xml"/>
-<Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideMaster" Target="slideMasters/slideMaster1.xml"/>
-```
-
-**`ppt/slides/_rels/slide1.xml.rels`:**
-```xml
-<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout" Target="../slideLayouts/slideLayout1.xml"/>
-<Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="../media/image1.png"/>
-```
-
-**`[Content_Types].xml`:**
-```xml
-<Default Extension="png" ContentType="image/png"/>
-<Default Extension="jpg" ContentType="image/jpeg"/>
-<Override PartName="/ppt/slides/slide1.xml" ContentType="application/vnd.openxmlformats-officedocument.presentationml.slide+xml"/>
-```
-
-**`ppt/presentation.xml`:**
-```xml
-<p:sldIdLst>
-  <p:sldId id="256" r:id="rId1"/>
-  <p:sldId id="257" r:id="rId2"/>
-</p:sldIdLst>
-```
-
-**`docProps/app.xml`:** Update slide count and statistics
-```xml
-<Slides>2</Slides>
-<Paragraphs>10</Paragraphs>
-<Words>50</Words>
-```
-
-## Slide Operations
-
-### Adding a New Slide
-When adding a slide to the end of the presentation:
-
-1. **Create the slide file** (`ppt/slides/slideN.xml`)
-2. **Update `[Content_Types].xml`**: Add Override for the new slide
-3. **Update `ppt/_rels/presentation.xml.rels`**: Add relationship for the new slide
-4. **Update `ppt/presentation.xml`**: Add slide ID to `<p:sldIdLst>`
-5. **Create slide relationships** (`ppt/slides/_rels/slideN.xml.rels`) if needed
-6. **Update `docProps/app.xml`**: Increment slide count and update statistics (if present)
-
-### Duplicating a Slide
-1. Copy the source slide XML file with a new name
-2. Update all IDs in the new slide to be unique
-3. Follow the "Adding a New Slide" steps above
-4. **CRITICAL**: Remove or update any notes slide references in `_rels` files
-5. Remove references to unused media files
-
-### Reordering Slides
-1. **Update `ppt/presentation.xml`**: Reorder `<p:sldId>` elements in `<p:sldIdLst>`
-2. The order of `<p:sldId>` elements determines slide order
-3. Keep slide IDs and relationship IDs unchanged
-
-Example:
-```xml
-<!-- Original order -->
-<p:sldIdLst>
-  <p:sldId id="256" r:id="rId2"/>
-  <p:sldId id="257" r:id="rId3"/>
-  <p:sldId id="258" r:id="rId4"/>
-</p:sldIdLst>
-
-<!-- After moving slide 3 to position 2 -->
-<p:sldIdLst>
-  <p:sldId id="256" r:id="rId2"/>
-  <p:sldId id="258" r:id="rId4"/>
-  <p:sldId id="257" r:id="rId3"/>
-</p:sldIdLst>
-```
-
-### Deleting a Slide
-1. **Remove from `ppt/presentation.xml`**: Delete the `<p:sldId>` entry
-2. **Remove from `ppt/_rels/presentation.xml.rels`**: Delete the relationship
-3. **Remove from `[Content_Types].xml`**: Delete the Override entry
-4. **Delete files**: Remove `ppt/slides/slideN.xml` and `ppt/slides/_rels/slideN.xml.rels`
-5. **Update `docProps/app.xml`**: Decrement slide count and update statistics
-6. **Clean up unused media**: Remove orphaned images from `ppt/media/`
-
-Note: Don't renumber remaining slides - keep their original IDs and filenames.
-
-
-## Common Errors to Avoid
-
-- **Encodings**: Escape unicode characters in ASCII content: `"` becomes `&#8220;`
-- **Images**: Add to `ppt/media/` and update relationship files
-- **Lists**: Omit bullets from list headers
-- **IDs**: Use valid hexadecimal values for UUIDs
-- **Themes**: Check all themes in `theme` directory for colors
-
-## Validation Checklist for Template-Based Presentations
-
-### Before Packing, Always:
-- **Clean unused resources**: Remove unreferenced media, fonts, and notes directories
-- **Fix Content_Types.xml**: Declare ALL slides, layouts, and themes present in the package
-- **Fix relationship IDs**: 
-   - Remove font embed references if not using embedded fonts
-- **Remove broken references**: Check all `_rels` files for references to deleted resources
-
-### Common Template Duplication Pitfalls:
-- Multiple slides referencing the same notes slide after duplication
-- Image/media references from template slides that no longer exist
-- Font embedding references when fonts aren't included
-- Missing slideLayout declarations for layouts 12-25
-- docProps directory may not unpack - this is optional

-#!/usr/bin/env python3
-"""
-Create thumbnail grids from PowerPoint presentation slides.
-
-Creates a grid layout of slide thumbnails with configurable columns (max 6).
-Each grid contains up to cols×(cols+1) images. For presentations with more
-slides, multiple numbered grid files are created automatically.
-
-The program outputs the names of all files created.
-
-Output:
-- Single grid: {prefix}.jpg (if slides fit in one grid)
-- Multiple grids: {prefix}-1.jpg, {prefix}-2.jpg, etc.
-
-Grid limits by column count:
-- 3 cols: max 12 slides per grid (3×4)
-- 4 cols: max 20 slides per grid (4×5)
-- 5 cols: max 30 slides per grid (5×6) [default]
-- 6 cols: max 42 slides per grid (6×7)
-
-Usage:
-    python thumbnail.py input.pptx [output_prefix] [--cols N] [--outline-placeholders]
-
-Examples:
-    python thumbnail.py presentation.pptx
-    # Creates: thumbnails.jpg (using default prefix)
-    # Outputs:
-    #   Created 1 grid(s):
-    #     - thumbnails.jpg
-
-    python thumbnail.py large-deck.pptx grid --cols 4
-    # Creates: grid-1.jpg, grid-2.jpg, grid-3.jpg
-    # Outputs:
-    #   Created 3 grid(s):
-    #     - grid-1.jpg
-    #     - grid-2.jpg
-    #     - grid-3.jpg
-
-    python thumbnail.py template.pptx analysis --outline-placeholders
-    # Creates thumbnail grids with red outlines around text placeholders

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,
+        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)

+        })
+      ]
+    })
+  ]
+})
+```
+
+**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 (`“` 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>
+```
