+
+## Quick Start
+
+```python
+from pypdf import PdfReader, PdfWriter
+
+# Read a PDF
+reader = PdfReader("document.pdf")
+print(f"Pages: {len(reader.pages)}")
+
+# Extract text
+text = ""
+for page in reader.pages:
+    text += page.extract_text()
+```
+
+## Python Libraries
+
+### pypdf - Basic Operations
+
+#### Merge PDFs
+```python
+from pypdf import PdfWriter, PdfReader

+    reader = PdfReader(pdf_file)
+    for page in reader.pages:
+        writer.add_page(page)
+
+with open("merged.pdf", "wb") as output:
+    writer.write(output)
+```
+
+#### Split PDF
+```python
+reader = PdfReader("input.pdf")
+for i, page in enumerate(reader.pages):
+    writer = PdfWriter()
+    writer.add_page(page)
+    with open(f"page_{i+1}.pdf", "wb") as output:
+        writer.write(output)
+```
+
+#### Extract Metadata
+```python
+reader = PdfReader("document.pdf")
+meta = reader.metadata
+print(f"Title: {meta.title}")
+print(f"Author: {meta.author}")
+print(f"Subject: {meta.subject}")
+print(f"Creator: {meta.creator}")
+```
+
+#### Rotate Pages
+```python
+reader = PdfReader("input.pdf")
+writer = PdfWriter()
+
+page = reader.pages[0]
+page.rotate(90)  # Rotate 90 degrees clockwise
+writer.add_page(page)
+
+with open("rotated.pdf", "wb") as output:
+    writer.write(output)
+```
+
+### pdfplumber - Text and Table Extraction
+
+#### Extract Text with Layout
+```python
+import pdfplumber
+
+with pdfplumber.open("document.pdf") as pdf:
+    for page in pdf.pages:
+        text = page.extract_text()
+        print(text)
+```
+
+#### Extract Tables
+```python
+with pdfplumber.open("document.pdf") as pdf:
+    for i, page in enumerate(pdf.pages):

+        for j, table in enumerate(tables):
+            print(f"Table {j+1} on page {i+1}:")
+            for row in table:
+                print(row)
+```
+
+#### Advanced Table Extraction
+```python
+import pandas as pd
+
+with pdfplumber.open("document.pdf") as pdf:
+    all_tables = []
+    for page in pdf.pages:
+        tables = page.extract_tables()
+        for table in tables:
+            if table:  # Check if table is not empty
+                df = pd.DataFrame(table[1:], columns=table[0])
+                all_tables.append(df)
+
+# Combine all tables
+if all_tables:
+    combined_df = pd.concat(all_tables, ignore_index=True)
+    combined_df.to_excel("extracted_tables.xlsx", index=False)
+```
+
+### reportlab - Create PDFs
+
+#### Basic PDF Creation

+**CRITICAL: You MUST complete these steps in order. Do not skip ahead to writing code.**
+
+If you need to fill out a PDF form, first check to see if the PDF has fillable form fields. Run this script from this file's directory:
+ `python scripts/check_fillable_fields <file.pdf>`, and depending on the result go to either the "Fillable fields" or "Non-fillable fields" and follow those instructions.
+
+# Fillable fields
+If the PDF has fillable form fields:
+- Run this script from this file's directory: `python scripts/extract_form_field_info.py <input.pdf> <field_info.json>`. It will create a JSON file with a list of fields in this format:
+```
+[
+  {
+    "field_id": (unique ID for the field),
+    "page": (page number, 1-based),
+    "rect": ([left, bottom, right, top] bounding box in PDF coordinates, y=0 is the bottom of the page),
+    "type": ("text", "checkbox", "radio_group", or "choice"),
+  },
+  // Checkboxes have "checked_value" and "unchecked_value" properties:
+  {
+    "field_id": (unique ID for the field),
+    "page": (page number, 1-based),
+    "type": "checkbox",
+    "checked_value": (Set the field to this value to check the checkbox),
+    "unchecked_value": (Set the field to this value to uncheck the checkbox),
+  },
+  // Radio groups have a "radio_options" list with the possible choices.
+  {
+    "field_id": (unique ID for the field),
+    "page": (page number, 1-based),
+    "type": "radio_group",
+    "radio_options": [
+      {
+        "value": (set the field to this value to select this radio option),
+        "rect": (bounding box for the radio button for this option)
+      },
+      // Other radio options
+    ]
+  },
+  // Multiple choice fields have a "choice_options" list with the possible choices:
+  {
+    "field_id": (unique ID for the field),
+    "page": (page number, 1-based),
+    "type": "choice",
+    "choice_options": [
+      {
+        "value": (set the field to this value to select this option),
+        "text": (display text of the option)
+      },
+      // Other choice options
+    ],
+  }
+]
+```
+- 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>

+
+### reportlab Advanced Features
+
+#### Create Professional Reports with Tables
+```python
+from reportlab.platypus import SimpleDocTemplate, Table, TableStyle, Paragraph
+from reportlab.lib.styles import getSampleStyleSheet
+from reportlab.lib import colors
+
+# Sample data
+data = [
+    ['Product', 'Q1', 'Q2', 'Q3', 'Q4'],

+```
+
+## Complex Workflows
+
+### Extract Figures/Images from PDF
+
+#### Method 1: Using pdfimages (fastest)
+```bash
+# Extract all images with original quality
+pdfimages -all document.pdf images/img
+```
+
+#### Method 2: Using pypdfium2 + Image Processing
+```python
+import pypdfium2 as pdfium
+from PIL import Image
+import numpy as np
+
+def extract_figures(pdf_path, output_dir):
+    pdf = pdfium.PdfDocument(pdf_path)
+    
+    for page_num, page in enumerate(pdf):
+        # Render high-resolution page
+        bitmap = page.render(scale=3.0)
+        img = bitmap.to_pil()
+        
+        # Convert to numpy for processing
+        img_array = np.array(img)
+        
+        # Simple figure detection (non-white regions)
+        mask = np.any(img_array != [255, 255, 255], axis=2)
+        
+        # Find contours and extract bounding boxes
+        # (This is simplified - real implementation would need more sophisticated detection)
+        
+        # Save detected figures
+        # ... implementation depends on specific needs
+```
+
+### Batch PDF Processing with Error Handling
+```python
+import os
+import glob
+from pypdf import PdfReader, PdfWriter
+import logging
+
+logging.basicConfig(level=logging.INFO)
+logger = logging.getLogger(__name__)
+
+def batch_process_pdfs(input_dir, operation='merge'):
+    pdf_files = glob.glob(os.path.join(input_dir, "*.pdf"))
+    
+    if operation == 'merge':
+        writer = PdfWriter()
+        for pdf_file in pdf_files:
+            try:
+                reader = PdfReader(pdf_file)
+                for page in reader.pages:
+                    writer.add_page(page)
+                logger.info(f"Processed: {pdf_file}")
+            except Exception as e:
+                logger.error(f"Failed to process {pdf_file}: {e}")
+                continue
+        
+        with open("batch_merged.pdf", "wb") as output:
+            writer.write(output)
+    
+    elif operation == 'extract_text':
+        for pdf_file in pdf_files:
+            try:
+                reader = PdfReader(pdf_file)
+                text = ""
+                for page in reader.pages:
+                    text += page.extract_text()
+                
+                output_file = pdf_file.replace('.pdf', '.txt')
+                with open(output_file, 'w', encoding='utf-8') as f:
+                    f.write(text)
+                logger.info(f"Extracted text from: {pdf_file}")
+                
+            except Exception as e:
+                logger.error(f"Failed to extract text from {pdf_file}: {e}")
+                continue
+```
+
+### Advanced PDF Cropping
+```python
+from pypdf import PdfWriter, PdfReader
+
+reader = PdfReader("input.pdf")
+writer = PdfWriter()
+
+# Crop page (left, bottom, right, top in points)
+page = reader.pages[0]
+page.mediabox.left = 50
+page.mediabox.bottom = 50
+page.mediabox.right = 550
+page.mediabox.top = 750
+
+writer.add_page(page)
+with open("cropped.pdf", "wb") as output:
+    writer.write(output)
+```
+
+## Performance Optimization Tips
+
+### 1. For Large PDFs
+- Use streaming approaches instead of loading entire PDF in memory
+- Use `qpdf --split-pages` for splitting large files
+- Process pages individually with pypdfium2
+
+### 2. For Text Extraction
+- `pdftotext -bbox-layout` is fastest for plain text extraction
+- Use pdfplumber for structured data and tables
+- Avoid `pypdf.extract_text()` for very large documents
+
+### 3. For Image Extraction
+- `pdfimages` is much faster than rendering pages
+- Use low resolution for previews, high resolution for final output
+
+### 4. For Form Filling
+- pdf-lib maintains form structure better than most alternatives
+- Pre-validate form fields before processing
+
+### 5. Memory Management
+```python
+# Process PDFs in chunks
+def process_large_pdf(pdf_path, chunk_size=10):
+    reader = PdfReader(pdf_path)
+    total_pages = len(reader.pages)
+    
+    for start_idx in range(0, total_pages, chunk_size):
+        end_idx = min(start_idx + chunk_size, total_pages)
+        writer = PdfWriter()
+        
+        for i in range(start_idx, end_idx):
+            writer.add_page(reader.pages[i])
+        
+        # Process chunk
+        with open(f"chunk_{start_idx//chunk_size}.pdf", "wb") as output:
+            writer.write(output)
+```
+
+## Troubleshooting Common Issues
+
+### Encrypted PDFs
+```python
+# Handle password-protected PDFs
+from pypdf import PdfReader
+
+try:
+    reader = PdfReader("encrypted.pdf")
+    if reader.is_encrypted:
+        reader.decrypt("password")
+except Exception as e:
+    print(f"Failed to decrypt: {e}")
+```
+
+### Corrupted PDFs
+```bash
+# Use qpdf to repair
+qpdf --check corrupted.pdf
+qpdf --replace-input corrupted.pdf
+```
+
+### Text Extraction Issues
+```python
+# Fallback to OCR for scanned PDFs
+import pytesseract
+from pdf2image import convert_from_path
+
+def extract_text_with_ocr(pdf_path):
+    images = convert_from_path(pdf_path)
+    text = ""
+    for i, image in enumerate(images):
+        text += pytesseract.image_to_string(image)
+    return text
+```

+description: Presentation creation, editing, and analysis. When OpenCode needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks
+license: Proprietary. LICENSE.txt has complete terms
+---
+
+# PPTX creation, editing, and analysis
+
+## Overview
+
+A user may ask you to create, edit, or analyze the contents of a .pptx file. A .pptx file is essentially a ZIP archive containing XML files and other resources that you can read or edit. You have different tools and workflows available for different tasks.
+
+## Reading and analyzing content
+
+### Text extraction
+If you just need to read the text contents of a presentation, you should convert the document to markdown:
+
+```bash
+# Convert document to markdown
+python -m markitdown path-to-file.pptx
+```
+
+### Raw XML access
+You need raw XML access for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. For any of these features, you'll need to 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):
+
+1. **Classic Blue**: Deep navy (#1C2833), slate gray (#2E4053), silver (#AAB7B8), off-white (#F4F6F6)
+2. **Teal & Coral**: Teal (#5EA8A7), deep teal (#277884), coral (#FE4447), white (#FFFFFF)
+3. **Bold Red**: Red (#C0392B), bright red (#E74C3C), orange (#F39C12), yellow (#F1C40F), green (#2ECC71)
+4. **Warm Blush**: Mauve (#A49393), blush (#EED6D3), rose (#E8B4B8), cream (#FAF7F2)
+5. **Burgundy Luxury**: Burgundy (#5D1D2E), crimson (#951233), rust (#C15937), gold (#997929)
+6. **Deep Purple & Emerald**: Purple (#B165FB), dark blue (#181B24), emerald (#40695B), white (#FFFFFF)
+7. **Cream & Forest Green**: Cream (#FFE1C7), forest green (#40695B), white (#FCFCFC)
+8. **Pink & Purple**: Pink (#F8275B), coral (#FF574A), rose (#FF737D), purple (#3D2F68)
+9. **Lime & Plum**: Lime (#C5DE82), plum (#7C3A5F), coral (#FD8C6E), blue-gray (#98ACB5)
+10. **Black & Gold**: Gold (#BF9A4A), black (#000000), cream (#F4F6F6)
+11. **Sage & Terracotta**: Sage (#87A96B), terracotta (#E07A5F), cream (#F4F1DE), charcoal (#2C2C2C)
+12. **Charcoal & Red**: Charcoal (#292929), red (#E33737), light gray (#CCCBCB)
+13. **Vibrant Orange**: Orange (#F96D00), light gray (#F2F2F2), charcoal (#222831)
+14. **Forest Green**: Black (#191A19), green (#4E9F3D), dark green (#1E5128), white (#FFFFFF)
+15. **Retro Rainbow**: Purple (#722880), pink (#D72D51), orange (#EB5C18), amber (#F08800), gold (#DEB600)
+16. **Vintage Earthy**: Mustard (#E3B448), sage (#CBD18F), forest green (#3A6B35), cream (#F4F1DE)
+17. **Coastal Rose**: Old rose (#AD7670), beaver (#B49886), eggshell (#F3ECDC), ash gray (#BFD5BE)
+18. **Orange & Turquoise**: Light orange (#FC993E), grayish turquoise (#667C6F), white (#FCFCFC)
+
+#### 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
+**When creating 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

+When edit slides in an existing PowerPoint presentation, you need to 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**
+
+When you need to create a presentation that follows an existing template's design, you'll need to duplicate and re-arrange template slides before then 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 you have exactly 2 distinct items/concepts
+     - Three-column layouts: Use ONLY when you have exactly 3 distinct items/concepts
+     - Image + text layouts: Use ONLY when you have actual images to insert
+     - Quote layouts: Use ONLY for actual quotes from people (with attribution), never for emphasis
+     - Never use layouts with more placeholders than you have content
+     - If you have 2 items, don't force them into a 3-column layout
+     - If you have 4+ items, consider breaking into multiple slides or using a list format
+   * Count your 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 your replacement JSON exist in the inventory
+     - If you reference a non-existent shape, you'll get an error showing available shapes
+     - If you reference a non-existent slide, you'll get an error indicating 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're 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.
+
+## Table of Contents
+
+1. [Creating HTML Slides](#creating-html-slides)
+2. [Using the html2pptx Library](#using-the-html2pptx-library)
+3. [Using PptxGenJS](#using-pptxgenjs)
+
+---
+
+## 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
+
+```javascript
+const tableData = [
+    // Header row with custom styling
+    [
+        { text: "Product", options: { fill: { color: "4472C4" }, color: "FFFFFF", bold: true } },
+        { text: "Revenue", options: { fill: { color: "4472C4" }, color: "FFFFFF", bold: true } },
+        { text: "Growth", options: { fill: { color: "4472C4" }, color: "FFFFFF", bold: true } }
+    ],
+    // Data rows
+    ["Product A", "$50M", "+15%"],
+    ["Product B", "$35M", "+22%"],
+    ["Product C", "$28M", "+8%"]
+];
+
+slide.addTable(tableData, {
+    x: 1,
+    y: 1.5,
+    w: 8,
+    h: 3,
+    colW: [3, 2.5, 2.5],  // Column widths
+    rowH: [0.5, 0.6, 0.6, 0.6],  // Row heights
+    border: { pt: 1, color: "CCCCCC" },
+    align: "center",
+    valign: "middle",
+    fontSize: 14
+});
+```
+
+#### Table with Merged Cells
+
+```javascript
+const mergedTableData = [
+    [
+        { text: "Q1 Results", options: { colspan: 3, fill: { color: "4472C4" }, color: "FFFFFF", bold: true } }
+    ],
+    ["Product", "Sales", "Market Share"],
+    ["Product A", "$25M", "35%"],
+    ["Product B", "$18M", "25%"]
+];
+
+slide.addTable(mergedTableData, {
+    x: 1,
+    y: 1,
+    w: 8,
+    h: 2.5,
+    colW: [3, 2.5, 2.5],
+    border: { pt: 1, color: "DDDDDD" }
+});
+```
+
+### 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"
+- `valign` - Vertical alignment: "top", "middle", "bottom"
+- `fontSize` - Text size
+- `autoPage` - Auto-create new slides if content overflows

+# 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

+
+## 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

+   See http://www.w3.org/XML/1998/namespace.html and

+
+    This schema document describes the XML namespace, in a form
+    suitable for import by other schema documents.  
+
+    Note that local names in this namespace are intended to be defined
+    only by the World Wide Web Consortium or its subgroups.  The
+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+  
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of 
+         the original XML Working Group.  This name is reserved by 
+         the following decision of the W3C XML Plenary and 
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang or xml:space attributes
+        on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+ 
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>
+ </xs:annotation>
+
+ <xs:annotation>
+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2001/03/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself.  In other words, if the XML Schema namespace changes, the version
+   of this document at
+   http://www.w3.org/2001/xml.xsd will change

+   http://www.w3.org/2001/03/xml.xsd will not change.

+/**
+ * html2pptx - Convert HTML slide to pptxgenjs slide with positioned elements
+ *
+ * USAGE:
+ *   const pptx = new pptxgen();
+ *   pptx.layout = 'LAYOUT_16x9';  // Must match HTML body dimensions
+ *
+ *   const { slide, placeholders } = await html2pptx('slide.html', pptx);
+ *   slide.addChart(pptx.charts.LINE, data, placeholders[0]);
+ *
+ *   await pptx.writeFile('output.pptx');
+ *
+ * FEATURES:
+ *   - Converts HTML to PowerPoint with accurate positioning
+ *   - Supports text, images, shapes, and bullet lists
+ *   - Extracts placeholder elements (class="placeholder") with positions
+ *   - Handles CSS gradients, borders, and margins
+ *
+ * VALIDATION:
+ *   - Uses body width/height from HTML for viewport sizing
+ *   - Throws error if HTML dimensions don't match presentation layout
+ *   - Throws error if content overflows body (with overflow details)
+ *
+ * RETURNS:
+ *   { slide, placeholders } where placeholders is an array of { id, x, y, w, h }

+"""
+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

+
+## What this is
+
+AI writing has patterns. Predictable phrases, structures, rhythms. This skill teaches Claude (or any LLM) to catch and remove them.
+
+## Skill Structure
+
+```

+
+## Quick start
+
+**Claude Code:** Add this folder as a skill.
+
+**Claude Projects:** Upload `SKILL.md` and reference files to project knowledge.
+
+**Custom instructions:** Copy core rules from `SKILL.md`.
+
+**API calls:** Include `SKILL.md` in your system prompt. Reference files load on demand.
+
+## What it catches
+
+**Banned phrases** - Throat-clearing openers, emphasis crutches, business jargon, all adverbs, vague declaratives, meta-commentary. See `references/phrases.md`.
+
+**Structural clichés** - Binary contrasts, negative listings, dramatic fragmentation, rhetorical setups, false agency, narrator-from-a-distance voice, passive voice. See `references/structures.md`.
+
+**Sentence-level rules** - No Wh- sentence starters, no em dashes, no staccato fragmentation, no lazy extremes, active voice required.
+

+description: Remove AI writing patterns from prose. Use when drafting, editing, or reviewing text to eliminate predictable AI tells.
+metadata:
+  trigger: Writing prose, editing drafts, reviewing content for AI patterns
+  author: Hardik Pandya (https://hvpandya.com)

+
+# Stop Slop
+
+Eliminate predictable AI writing patterns from prose.
+
+## Core Rules
+
+1. **Cut filler phrases.** Remove throat-clearing openers, emphasis crutches, and all adverbs. See [references/phrases.md](references/phrases.md).
+
+2. **Break formulaic structures.** Avoid binary contrasts, negative listings, dramatic fragmentation, rhetorical setups, false agency. See [references/structures.md](references/structures.md).
+
+3. **Use active voice.** Every sentence needs a human subject doing something. No passive constructions. No inanimate objects performing human actions ("the complaint becomes a fix").
+
+4. **Be specific.** No vague declaratives ("The reasons are structural"). Name the specific thing. No lazy extremes ("every," "always," "never") doing vague work.
+
+5. **Put the reader in the room.** No narrator-from-a-distance voice. "You" beats "People." Specifics beat abstractions.
+
+6. **Vary rhythm.** Mix sentence lengths. Two items beat three. End paragraphs differently. No em dashes.
+
+7. **Trust readers.** State facts directly. Skip softening, justification, hand-holding.
+
+8. **Cut quotables.** If it sounds like a pull-quote, rewrite it.
+
+## Quick Checks
+
+Before delivering prose:
+
+- Any adverbs? Kill them.
+- Any passive voice? Find the actor, make them the subject.
+- Inanimate thing doing a human verb ("the decision emerges")? Name the person.
+- Sentence starts with a Wh- word? Restructure it.
+- Any "here's what/this/that" throat-clearing? Cut to the point.
+- Any "not X, it's Y" contrasts? State Y directly.
+- Three consecutive sentences match length? Break one.
+- Paragraph ends with punchy one-liner? Vary it.
+- Em-dash anywhere? Remove it.
+- Vague declarative ("The implications are significant")? Name the specific implication.
+- Narrator-from-a-distance ("Nobody designed this")? Put the reader in the scene.
+- Meta-joiners ("The rest of this essay...")? Delete. Let the essay move.

+# Before/After Examples
+
+## Example 1: Throat-Clearing + Binary Contrast
+
+**Before:**
+> "Here's the thing: building products is hard. Not because the technology is complex. Because people are complex. Let that sink in."
+
+**After:**
+> "Building products is hard. Technology is manageable. People aren't."
+
+**Changes:** Removed opener, binary contrast structure, and emphasis crutch. Direct statements.
+
+---
+
+## Example 2: Filler + Unnecessary Reassurance
+
+**Before:**
+> "It turns out that most teams struggle with alignment. The uncomfortable truth is that nobody wants to admit they're confused. And that's okay."
+
+**After:**
+> "Teams struggle with alignment. Nobody admits confusion."
+
+**Changes:** Cut hedging ("most"), removed throat-clearing phrases, deleted permission-granting ending.
+
+---
+
+## Example 3: Business Jargon Stack
+
+**Before:**
+> "In today's fast-paced landscape, we need to lean into discomfort and navigate uncertainty with clarity. This matters because your competition isn't waiting."
+
+**After:**
+> "Move faster. Your competition is."
+
+**Changes:** Eliminated jargon entirely. Core message in six words.
+
+---
+
+## Example 4: Dramatic Fragmentation
+
+**Before:**
+> "Speed. Quality. Cost. You can only pick two. That's it. That's the tradeoff."
+
+**After:**
+> "Speed, quality, cost—pick two."
+
+**Changes:** Single sentence. No performative emphasis.
+
+---
+
+## Example 5: Rhetorical Setup
+
+**Before:**
+> "What if I told you that the best teams don't optimize for productivity? Here's what I mean: they optimize for learning. Think about it."
+
+**After:**
+> "The best teams optimize for learning, not productivity."
+
+**Changes:** Direct claim. No rhetorical scaffolding.

+# Phrases to Remove
+
+## Throat-Clearing Openers
+
+Remove these announcement phrases. State the content directly.
+
+- "Here's the thing:"
+- "Here's what [X]"
+- "Here's this [X]"
+- "Here's that [X]"
+- "Here's why [X]"
+- "The uncomfortable truth is"
+- "It turns out"
+- "The real [X] is"
+- "Let me be clear"
+- "The truth is,"
+- "I'll say it again:"
+- "I'm going to be honest"
+- "Can we talk about"
+- "Here's what I find interesting"
+- "Here's the problem though"
+
+Any "here's what/this/that" construction is throat-clearing before the point. Cut it and state the point.
+
+## Emphasis Crutches
+
+These add no meaning. Delete them.
+
+- "Full stop." / "Period."
+- "Let that sink in."
+- "This matters because"
+- "Make no mistake"
+- "Here's why that matters"
+
+## Business Jargon
+
+Replace with plain language.
+
+| Avoid | Use instead |
+|-------|-------------|
+| Navigate (challenges) | Handle, address |
+| Unpack (analysis) | Explain, examine |
+| Lean into | Accept, embrace |
+| Landscape (context) | Situation, field |
+| Game-changer | Significant, important |
+| Double down | Commit, increase |
+| Deep dive | Analysis, examination |
+| Take a step back | Reconsider |
+| Moving forward | Next, from now |
+| Circle back | Return to, revisit |
+| On the same page | Aligned, agreed |
+
+## Adverbs
+
+Kill all adverbs. No -ly words. No softeners, no intensifiers, no hedges.
+
+Specific offenders:
+
+- "really"
+- "just"
+- "literally"
+- "genuinely"
+- "honestly"
+- "simply"
+- "actually"
+- "deeply"
+- "truly"
+- "fundamentally"
+- "inherently"
+- "inevitably"
+- "interestingly"
+- "importantly"
+- "crucially"
+
+Also cut these filler phrases:
+
+- "At its core"
+- "In today's [X]"
+- "It's worth noting"
+- "At the end of the day"
+- "When it comes to"
+- "In a world where"
+- "The reality is"
+
+## Meta-Commentary
+
+Remove self-referential asides. The essay should move, not announce its own structure.
+
+- "Hint:"
+- "Plot twist:" / "Spoiler:"
+- "You already know this, but"
+- "But that's another post"
+- "X is a feature, not a bug"
+- "Dressed up as"
+- "The rest of this essay explains..."
+- "Let me walk you through..."
+- "In this section, we'll..."
+- "As we'll see..."
+- "I want to explore..."
+
+## Performative Emphasis
+
+False intimacy or manufactured sincerity:
+
+- "creeps in"
+- "I promise"
+- "They exist, I promise"
+
+## Telling Instead of Showing
+
+Announcing difficulty or significance rather than demonstrating it:
+
+- "This is genuinely hard"
+- "This is what leadership actually looks like"
+- "This is what X actually looks like"
+- "actually matters"
+
+## Vague Declaratives
+
+Sentences that announce importance without naming the specific thing. Kill these.
+
+- "The reasons are structural"
+- "The implications are significant"
+- "This is the deepest problem"
+- "The stakes are high"
+- "The consequences are real"
+
+If a sentence says something is important/deep/structural without showing the specific thing, cut it or replace it with the specific thing.

+# Structures to Avoid
+
+## Binary Contrasts
+
+These create false drama. State the point directly.
+
+| Pattern | Problem |
+|---------|---------|
+| "Not because X. Because Y." / "Not because X, but because Y." | Telegraphed reversal |
+| "[X] isn't the problem. [Y] is." | Formulaic reframe |
+| "The answer isn't X. It's Y." | Predictable pivot |
+| "It feels like X. It's actually Y." | Setup/reveal cliche |
+| "The question isn't X. It's Y." | Rhetorical misdirection |
+| "Not X. But Y." / "not X, it's Y" / "isn't X, it's Y" | Mechanical contrast |
+| "It's not this. It's that." | Same formula, different words |
+| "stops being X and starts being Y" | False transformation arc |
+| "doesn't mean X, but actually Y" | Negation-then-assertion crutch |
+| "is about X but not Y" | False distinction |
+| "not just X but also Y" | Additive hedge |
+
+**Instead:** State Y directly. "The problem is Y." "Y matters here." Drop the negation entirely.
+
+## Negative Listing
+
+Listing what something is *not* before revealing what it *is*. A rhetorical striptease.
+
+| Pattern | Problem |
+|---------|---------|
+| "Not a X... Not a Y... A Z." | Dramatic buildup through negation |
+| "It wasn't X. It wasn't Y. It was Z." | Same structure, past tense |
+
+**Instead:** State Z. The reader doesn't need the runway.
+
+## Dramatic Fragmentation
+
+Sentence fragments for emphasis read as manufactured profundity.
+
+| Pattern | Problem |
+|---------|---------|
+| "[Noun]. That's it. That's the [thing]." | Performative simplicity |
+| "X. And Y. And Z." | Staccato drama |
+| "This unlocks something. [Word]." | Artificial revelation |
+
+**Instead:** Complete sentences. Trust content over presentation.
+
+## Rhetorical Setups
+
+These announce insight rather than deliver it.
+
+| Pattern | Problem |
+|---------|---------|
+| "What if [reframe]?" | Socratic posturing |
+| "Here's what I mean:" | Redundant preview |
+| "Think about it:" | Condescending prompt |
+| "And that's okay." | Unnecessary permission |
+
+**Instead:** Make the point. Let readers draw conclusions.
+
+## Formulaic Constructions
+
+| Pattern | Problem |
+|---------|---------|
+| "By the time X, I was Y." | Narrative template |
+| "X that isn't Y" | Indirect. Say "X is broken" |
+
+## False Agency
+
+Giving inanimate things human verbs. Complaints don't "become" fixes. Bets don't "live or die." Decisions don't "emerge." A person does something to make those things happen. AI loves this because it avoids naming the actor.
+
+| Pattern | Problem |
+|---------|---------|
+| "a complaint becomes a fix" | The complaint did nothing. Someone fixed it. |
+| "a bet lives or dies in days" | Bets don't have lifespans. Someone kills the project or ships it. |
+| "the decision emerges" | Decisions don't emerge. Someone decides. |
+| "the culture shifts" | Cultures don't shift on their own. People change behavior. |
+| "the conversation moves toward" | Conversations don't move. Someone steers. |
+| "the data tells us" | Data sits there. Someone reads it and draws a conclusion. |
+| "the market rewards" | Markets don't reward. Buyers pay for things. |
+
+**Instead:** Name the human. "The team fixed it that week" beats "the complaint becomes a fix." If no specific person fits, use "you" to put the reader in the seat.
+
+## Narrator-from-a-Distance
+
+Floating above the scene instead of putting the reader in it.
+
+| Pattern | Problem |
+|---------|---------|
+| "Nobody designed this." | Disembodied observation |
+| "This happens because..." | Lecturer voice |
+| "This is why..." | Same |
+| "People tend to..." | Armchair sociologist |
+
+**Instead:** Put the reader in the room. "You don't sit down one day and decide to..." beats "Nobody designed this."
+
+## Passive Voice
+
+Every sentence needs a subject doing something. Passive voice hides the actor and drains energy.
+
+| Pattern | Fix |
+|---------|-----|
+| "X was created" | Name who created it |
+| "It is believed that" | Name who believes it |
+| "Mistakes were made" | Name who made them |
+| "The decision was reached" | Name who decided |
+
+**Instead:** Find the actor. Put them at the front of the sentence.
+
+## Sentence Starters to Avoid
+
+| Pattern | Fix |
+|---------|-----|
+| Sentences starting with What, When, Where, Which, Who, Why, How | Restructure. Lead with the subject or the verb. |
+| Paragraphs starting with "So" | Start with content |
+| Sentences starting with "Look," | Remove |
+
+Wh- openers become a crutch. "What makes this hard is..." becomes "The constraint is..." or better, name the specific constraint.
+
+## Rhythm Patterns
+
+| Pattern | Fix |
+|---------|-----|
+| Three-item lists | Use two items or one |
+| Questions answered immediately | Let questions breathe or cut them |
+| Every paragraph ends punchily | Vary endings |
+| Em-dashes | Remove. Use commas or periods. No em dashes at all. |
+| Staccato fragmentation | Don't stack short punchy sentences |
+| "Not always. Not perfectly." | Hedging disguised as reassurance |
+
+## Word Patterns
+
+| Pattern | Problem |
+|---------|---------|
+| Lazy extremes (every, always, never, everyone, everybody, nobody) | False authority. Use specifics instead of sweeping claims. |
+| All adverbs (-ly words, "really," "just," "literally," "genuinely," "honestly," "simply," "actually") | Empty emphasis. See phrases.md for full list. |

+# Skill mechanics
+
+The skill-specific branch of [`writing-for-agents`](SKILL.md): what changes when the document is a skill (frontmatter, the invocation choice, and router skills). Everything else about writing it is the universal reference in `SKILL.md`.
+
+## Invocation
+
+Two choices, trading the two loads:
+
+- A **model-invoked** skill keeps a `description`, so the agent can fire it autonomously, and other skills can reach it. You can still type its name: model-invocation always _includes_ user reach; a description only ever adds agent discovery, never removes the human's. The description is the skill's top-level context pointer, forced to stay loaded at all times: permanent context load in exchange for discoverability. A model-invoked skill whose content is all reference is also one home for shared reference: another skill can invoke it, so reference needed by several skills lives in one place. Mechanics: omit `disable-model-invocation`, and write a model-facing description carrying the trigger branches (the pointer-writing rules in `SKILL.md` apply in full).
+- A **user-invoked** skill strips the description from the agent's reach: only the human typing its name can invoke it, and no other skill can. Zero context load, but it spends cognitive load: you are the index that must remember it exists. Mechanics: set `disable-model-invocation: true`; the `description` becomes human-facing: a one-line summary, trigger lists stripped.
+
+Pick model-invocation only when the agent must reach the skill on its own, or another skill must. If it only ever fires by hand, make it user-invoked and pay no context load.
+
+Shared reference that two user-invoked skills both need can live in neither: with no descriptions, neither can fire the other. Push it to a plain file outside the skill system: external reference any skill can point at.
+
+## Splitting by invocation
+
+The invocation cut of splitting (the sequence cut lives in `SKILL.md`): split off a model-invoked skill when you have a distinct leading word that should trigger it on its own (a trigger word you actually use in your prompts), or another skill must reach it. You pay context load for the new always-loaded description, so that independent reach has to be worth it.
+
+## Router skills
+
+When user-invoked skills multiply past what you can remember, that piled-up cognitive load is cured by a **router skill**: one user-invoked skill that names the others and when to reach for each, so the human has one skill to remember instead of many. It can only hint, never fire them: user-invoked skills have no description, so nothing but the human can reach them.

+name: writing-for-agents
+description: Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.
+---
+
+Reference for writing any document an agent consumes: a skill, an `AGENTS.md` / `CLAUDE.md`, a doc reached by a pointer. The packaging differs; the writing does not: the same levers make each one predictable, since the agent takes the same _process_ every run rather than producing the same output.
+
+When the document you're writing is a skill, read [`SKILL-MECHANICS.md`](SKILL-MECHANICS.md) for frontmatter, invocation choice, and router skills.
+
+## Context pointers
+
+A **context pointer** is a reference held in the agent's context that names some out-of-context material and encodes the condition for reaching it. A skill's description is one; a line in `AGENTS.md` naming a doc is the same object. The pointer's _wording_, not its target, decides when the agent reaches the material, and how reliably. A must-have target behind a weakly worded pointer is a variance bug: sharpen the wording first, and inline the material only if sharpening fails.
+
+A pointer does two jobs: state what the material is, and list the **branches** that should trigger reaching it (a branch is a distinct case the document handles, so different runs take different paths through it). Every word of an always-loaded pointer costs on every turn, so it earns even harder pruning than the body:
+
+- **Front-load the leading word**: the pointer is where it does its triggering work.
+- **One trigger per branch.** Synonyms that rename a single branch are one branch written twice; collapse them and keep only genuinely distinct branches.
+- **Cut identity the body already carries.**
+
+## The two loads
+
+Every document and pointer you add spends one of two budgets:
+
+- **Context load** is the cost of always-loaded material on the agent's window: an `AGENTS.md` line, a skill description, anything sitting in context every turn, spending tokens and attention whether or not it fires.
+- **Cognitive load** is the cost on the human: which documents exist and when to reach for each. The human is the index. Not a cost to minimise: it is the price of human agency; spend it where human judgement matters, remove it where it does not.
+
+Material reached only through a pointer escapes context load at the price of the pointer's own line; material with no pointer at all rides entirely on cognitive load.
+
+## Information hierarchy
+
+A document is built from two content types: **steps** (the ordered actions the agent performs) and **reference** (definitions, rules, facts consulted on demand). The two mix freely: all steps (a recipe), all reference (a review's rules, this skill), or both. The core decision is where each piece sits on the **information hierarchy**, a ladder ranked by how immediately the agent needs the material:
+
+1. **In-file step** is the primary tier: what the agent does, in order.
+2. **In-file reference** is consulted on demand. Often a legitimately flat peer-set (every rule of a review on one rung), which is a fine arrangement, not a smell.
+3. **Disclosed reference** is pushed out into a separate file, reached by a context pointer, loaded only when the pointer fires. Spans a sibling file in the same folder through fully external reference that lives anywhere and any document can point at.
+
+Push too little down and the top bloats; push too much and you hide material the agent actually needs. That tension is the whole decision.
+
+**Progressive disclosure** is the move down the ladder (out of the main file and behind a pointer) so the top stays legible. Not primarily a token optimisation: it is how the hierarchy is protected. Branching is the cleanest disclosure test: inline what every branch needs, and push behind a pointer what only some branches reach. When a document has steps, in-file reference that should be disclosed buries them and turns attending to them into a coin-flip: a variance lever, not just a legibility one.
+
+**Co-location** is the within-file companion: where the ladder decides _how far down_ a piece sits, co-location decides _what sits beside it_ once there. Keep a concept's definition, rules, and caveats under one heading rather than scattered, so reading one part brings its neighbours with it. The test: the document should read like documentation written for the agent. Grouped material reads that way; scattered material does not. (Distinct from duplication: that repeats one meaning in two places; scattering fragments one meaning across many.)
+
+**Sprawl** is the failure mode here: a document simply too long, even when every line is live and unique. Attention thins across the excess, and every extra line is one more to keep relevant. The cure is the ladder: disclose reference behind pointers, and split by branch or sequence so each path carries only what it needs.
+
+## Steps and completion criteria
+
+Every step ends on a **completion criterion**, the condition that tells the agent the work is done. Two properties make it a lever:
+
+- **Clarity**: can the agent tell done from not-done? A vague bound ("understanding reached") invites **premature completion**: ending the step before it is genuinely done, attention slipping to _being done_. The visible steps still ahead (the **post-completion steps**) supply the pull; the criterion's clarity is the resistance. Defend in order: **sharpen the bound first** (local and cheap); only if it is irreducibly fuzzy _and_ you observe the rush, hide the later steps by splitting the sequence. Hiding only works across a real context boundary (a hand-off or a subagent dispatch; an inline call leaves the later steps in context and clears nothing).
+- **Demand**: how much it requires. "Every modified model accounted for" forces thorough work where "produce a change list" does not. Demand drives **legwork** (the digging the agent does within the work, latent in the wording rather than written as its own step), and it is not step-bound: "every rule applied" binds a body of flat reference just as "every step done" binds a sequence, which is how an all-reference document still carries an exhaustiveness bar.
+
+The strongest criteria are both checkable and exhaustive.
+
+## When to split
+
+Splitting one document into two spends one of the two loads, so split only when the cut earns it:
+
+- **By sequence**: split a run of steps where the post-completion steps tempt the agent to rush the one in front of it. Keeping them out of view drives more legwork on the current task. Beware the reverse: merging sequences exposes each step's later steps to what follows, inviting premature completion.
+- **By invocation**, skill-specific: see [`SKILL-MECHANICS.md`](SKILL-MECHANICS.md).
+
+## Leading words
+
+A **leading word** is a compact concept already living in the model's pretraining that the agent thinks with while running the document (_lesson_, _fog of war_, _tracer bullets_). Repeated as a token, never as a sentence, it accumulates a distributed definition and anchors a whole region of behaviour in the fewest tokens, by recruiting priors the model already holds. Coining your own works if you define it clearly, but a made-up word recruits no priors: you pay in definition tokens what a pretrained word gives free; reach for an existing word first.
+
+It anchors twice. In the body, _execution_: the agent reaches for the same behaviour every time the word appears, and inside flat reference it focuses attention on a class of thing to look for. In a pointer, _invocation_: when the same word lives in your prompts, your docs, and your codebase, the agent links that shared language to the material and reaches it more reliably.
+
+Hunt for opportunities to refactor with leading words. A triad spelled out at three sites, a pointer spending a sentence to gesture at one idea. Each is a passage begging to collapse into a single token:
+
+- "fast, deterministic, low-overhead" → _tight_ (a _tight_ loop).
+- "a loop you believe in" → _red_, turning a fuzzy gate into a binary observable state (the loop goes _red_ on the bug, or it doesn't).
+
+You win twice: fewer tokens, and a sharper hook for the agent to hang its thinking on. Assume every document is carrying restatements that leading words retire. Go find them.
+
+**Negation** is the failure mode beside this lever: steering by prohibition drags the forbidden behaviour into context and makes it _more_ available, not less. _Don't think of an elephant_, and the elephant is all there is; the negation is a weak modifier the strongly-activated concept overruns, so the ban half-reads as an instruction to do the thing. Prompt the **positive**: state the target behaviour ("write one-line comments") so the banned one is never spoken. A prohibition earns its place only as a hard guardrail you cannot phrase positively; even then, pair it with the positive target so attention lands on what to do.
+
+## Pruning
+
+- Keep each meaning in a **single source of truth**: one authoritative place, so changing the behaviour is a one-place edit. **Duplication** (the same meaning in more than one place) costs maintenance and tokens, and inflates a meaning's prominence on the ladder past its real rank. (The accidental inverse of a leading word, which repeats a token on purpose, never the meaning.)
+- The **environment** is a source of truth too (`package.json` scripts, config files, the directory layout, `--help` output), and a document that restates it is a **cache**: a copy of a lookup, earning its load only when the lookup is expensive. Cache what the agent cannot find by looking: the unwritten convention, the reason behind a choice, the gotcha no config confesses. Leave the one-file, one-command lookups to the environment, where they cannot go stale.
+- Check every line for **relevance**: does it still bear on what the document does? A line loses relevance by never bearing on the task (mere exposition, or a branch that should be disclosed) or by going stale as the behaviour or world it describes changes. Shorter documents are easier to keep relevant. Without a pruning discipline the default fate is **sediment**: stale layers that settle because adding feels safe and removing feels risky, until you must core down through them to find what is still live.
+- Hunt **no-ops** sentence by sentence: an instruction the model already obeys by default pays load to say nothing. The test (does it change behaviour versus the default?) is model-relative, not reader-relative: two people disagreeing about a no-op disagree about the default, and settle it by running the document, not by debate. When a sentence fails, delete the whole sentence rather than trim words from it. The test also grades leading words: a word too weak to beat the default (_be thorough_ when the agent is already thorough-ish) is a no-op, and the fix is a stronger word (_relentless_), not a different technique.

+
+# XLSX creation, editing, and analysis
+
+## Overview
+
+A user may ask you to create, edit, or analyze the contents of an .xlsx file. You have different tools and workflows available for different tasks.
+
+## Important Requirements
+
+**LibreOffice Required for Formula Recalculation**: You can assume LibreOffice is installed for recalculating formula values using the `recalc.py` script. The script automatically configures LibreOffice on first run
+
+## Reading and analyzing data
+
+### Data analysis with pandas
+For data analysis, visualization, and basic operations, use **pandas** which provides powerful data manipulation capabilities:
+
+```python
+import pandas as pd
+
+# Read Excel
+df = pd.read_excel('file.xlsx')  # Default: first sheet
+all_sheets = pd.read_excel('file.xlsx', sheet_name=None)  # All sheets as dict
+
+# Analyze
+df.head()      # Preview data
+df.info()      # Column info
+df.describe()  # Statistics
+
+# Write Excel
+df.to_excel('output.xlsx', index=False)
+```
+
+## Excel File Workflows
+
+## CRITICAL: Use Formulas, Not Hardcoded Values
+
+**Always use Excel formulas instead of calculating values in Python and hardcoding them.** This ensures the spreadsheet remains dynamic and updateable.
+
+### ❌ WRONG - Hardcoding Calculated Values
+```python
+# Bad: Calculating in Python and hardcoding result
+total = df['Sales'].sum()
+sheet['B10'] = total  # Hardcodes 5000
+
+# Bad: Computing growth rate in Python
+growth = (df.iloc[-1]['Revenue'] - df.iloc[0]['Revenue']) / df.iloc[0]['Revenue']
+sheet['C5'] = growth  # Hardcodes 0.15
+
+# Bad: Python calculation for average
+avg = sum(values) / len(values)
+sheet['D20'] = avg  # Hardcodes 42.5
+```
+
+### ✅ CORRECT - Using Excel Formulas
+```python
+# Good: Let Excel calculate the sum
+sheet['B10'] = '=SUM(B2:B9)'
+
+# Good: Growth rate as Excel formula
+sheet['C5'] = '=(C4-C2)/C2'
+
+# Good: Average using Excel function
+sheet['D20'] = '=AVERAGE(D2:D19)'
+```
+
+This applies to ALL calculations - totals, percentages, ratios, differences, etc. The spreadsheet should be able to recalculate when source data changes.
+
+## Common Workflow
+1. **Choose tool**: pandas for data, openpyxl for formulas/formatting
+2. **Create/Load**: Create new workbook or load existing file
+3. **Modify**: Add/edit data, formulas, and formatting
+4. **Save**: Write to file
+5. **Recalculate formulas (MANDATORY IF USING FORMULAS)**: Use the recalc.py script
+   ```bash
+   python recalc.py output.xlsx
+   ```
+6. **Verify and fix any errors**: 
+   - The script returns JSON with error details
+   - If `status` is `errors_found`, check `error_summary` for specific error types and locations
+   - Fix the identified errors and recalculate again
+   - Common errors to fix:
+     - `#REF!`: Invalid cell references
+     - `#DIV/0!`: Division by zero
+     - `#VALUE!`: Wrong data type in formula
+     - `#NAME?`: Unrecognized formula name
+
+### Creating new Excel files
+
+```python
+# Using openpyxl for formulas and formatting
+from openpyxl import Workbook
+from openpyxl.styles import Font, PatternFill, Alignment
+
+wb = Workbook()
+sheet = wb.active
+
+# Add data
+sheet['A1'] = 'Hello'
+sheet['B1'] = 'World'
+sheet.append(['Row', 'of', 'data'])
+
+# Add formula
+sheet['B2'] = '=SUM(A1:A10)'
+
+# Formatting
+sheet['A1'].font = Font(bold=True, color='FF0000')
+sheet['A1'].fill = PatternFill('solid', start_color='FFFF00')
+sheet['A1'].alignment = Alignment(horizontal='center')
+
+# Column width
+sheet.column_dimensions['A'].width = 20
+
+wb.save('output.xlsx')
+```
+
+### Editing existing Excel files
+
+```python
+# Using openpyxl to preserve formulas and formatting
+from openpyxl import load_workbook
+
+# Load existing file
+wb = load_workbook('existing.xlsx')
+sheet = wb.active  # or wb['SheetName'] for specific sheet
+
+# Working with multiple sheets
+for sheet_name in wb.sheetnames:
+    sheet = wb[sheet_name]
+    print(f"Sheet: {sheet_name}")
+
+# Modify cells
+sheet['A1'] = 'New Value'
+sheet.insert_rows(2)  # Insert row at position 2
+sheet.delete_cols(3)  # Delete column 3
+
+# Add new sheet
+new_sheet = wb.create_sheet('NewSheet')
+new_sheet['A1'] = 'Data'
+
+wb.save('modified.xlsx')
+```
+
+## Recalculating formulas
+
+Excel files created or modified by openpyxl contain formulas as strings but not calculated values. Use the provided `recalc.py` script to recalculate formulas:
+
+```bash
+python recalc.py <excel_file> [timeout_seconds]
+```
+
+Example:
+```bash
+python recalc.py output.xlsx 30
+```
+
+The script:
+- Automatically sets up LibreOffice macro on first run
+- Recalculates all formulas in all sheets
+- Scans ALL cells for Excel errors (#REF!, #DIV/0!, etc.)
+- Returns JSON with detailed error locations and counts
+- Works on both Linux and macOS
+
+## Formula Verification Checklist
+
+Quick checks to ensure formulas work correctly:
+
+### Essential Verification
+- [ ] **Test 2-3 sample references**: Verify they pull correct values before building full model
+- [ ] **Column mapping**: Confirm Excel columns match (e.g., column 64 = BL, not BK)
+- [ ] **Row offset**: Remember Excel rows are 1-indexed (DataFrame row 5 = Excel row 6)
+
+### Common Pitfalls
+- [ ] **NaN handling**: Check for null values with `pd.notna()`
+- [ ] **Far-right columns**: FY data often in columns 50+ 
+- [ ] **Multiple matches**: Search all occurrences, not just first
+- [ ] **Division by zero**: Check denominators before using `/` in formulas (#DIV/0!)
+- [ ] **Wrong references**: Verify all cell references point to intended cells (#REF!)
+- [ ] **Cross-sheet references**: Use correct format (Sheet1!A1) for linking sheets
+
+### Formula Testing Strategy
+- [ ] **Start small**: Test formulas on 2-3 cells before applying broadly
+- [ ] **Verify dependencies**: Check all cells referenced in formulas exist
+- [ ] **Test edge cases**: Include zero, negative, and very large values
+
+### Interpreting recalc.py Output
+The script returns JSON with error details:

+
+## Best Practices
+
+### Library Selection
+- **pandas**: Best for data analysis, bulk operations, and simple data export
+- **openpyxl**: Best for complex formatting, formulas, and Excel-specific features
+
+### Working with openpyxl
+- Cell indices are 1-based (row=1, column=1 refers to cell A1)
+- Use `data_only=True` to read calculated values: `load_workbook('file.xlsx', data_only=True)`
+- **Warning**: If opened with `data_only=True` and saved, formulas are replaced with values and permanently lost
+- For large files: Use `read_only=True` for reading or `write_only=True` for writing
+- Formulas are preserved but not evaluated - use recalc.py to update values
+
+### Working with pandas
+- Specify data types to avoid inference issues: `pd.read_excel('file.xlsx', dtype={'id': str})`
+- For large files, read specific columns: `pd.read_excel('file.xlsx', usecols=['A', 'C', 'E'])`
+- Handle dates properly: `pd.read_excel('file.xlsx', parse_dates=['date_column'])`
+
+## Code Style Guidelines
+**IMPORTANT**: When generating Python code for Excel operations:
+- Write minimal, concise Python code without unnecessary comments
+- Avoid verbose variable names and redundant operations
+- Avoid unnecessary print statements
+
+**For Excel files themselves**:
+- Add comments to cells with complex formulas or important assumptions
+- Document data sources for hardcoded values
+- Include notes for key calculations and model sections
