Deep web search workflow using browser tools and multiple search engines such as Bing, Google, Baidu, Sogou/WeChat, 360, Toutiao, DuckDuckGo, Brave, Quark, or other available engines. Use when the user asks for deep_search, deep search, multi-engine research, source discovery, current web evidence, or when Codex needs to search, collect result links, de-duplicate sources, open candidate pages, and gather browser_snapshot/browser_extract evidence from each source.
Guide for creating effective skills. Use when users want to create a new skill, update an existing skill, inspect a prior session for failures, or improve one or more related skills from session evidence.
Generate and edit Draw.io-first diagrams for formal documents, reports, proposals, design documents, and implementation plans. Use Draw.io for flowcharts, sequence diagrams, class diagrams, Entity-Relationship (ER) diagrams, mind maps, architecture diagrams, UI wireframes, module dependency diagrams, and network topologies. Do not generate Mermaid for formal方案/设计文档; convert any existing Mermaid content into Draw.io diagrams and export PNG/SVG assets for insertion into Word/PDF/PPTX.
UI/UX design intelligence and implementation guidance for building polished interfaces. Use when the user asks for UI design, UX flows, information architecture, visual style direction, design systems/tokens, component specs, copy/microcopy, accessibility, or to generate/critique/refine frontend UI (HTML/CSS/JS, React, Next.js, Vue, Svelte, Tailwind). Includes workflows for (1) generating new UI layouts and styling, (2) improving existing UI/UX, (3) producing design-system tokens and component guidelines, and (4) turning UX recommendations into concrete code changes.
Generate reusable data charts from CSV files and chart specifications for reports, proposals, presentations, dashboards, and analytical documents. Use when Codex needs to create line charts, bar charts, scatter plots, correlation heatmaps, or chart image assets for insertion into Word/PDF/PPTX workflows.
Generate, rewrite, expand, or polish high-quality document text for solutions, reports, proposals, plans, presentations, or analysis before Word/PDF/PPT formatting. Use for text-first deliverables that may need planned figure insertions, including flowcharts, architecture diagrams, topology diagrams, process diagrams, design sketches, data charts, and analytical visualizations. Enforce Request → Plan → Draft → Audit → Refine → Deliver for complex writing tasks; allow streamlined handling for simple text-only requests.

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.
If you just need to read the text contents of a presentation, you should convert the document to markdown:
# Convert document to markdown
python -m markitdown path-to-file.pptx
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.
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.
ppt/presentation.xml - Main presentation metadata and slide referencesppt/slides/slide{N}.xml - Individual slide contents (slide1.xml, slide2.xml, etc.)ppt/notesSlides/notesSlide{N}.xml - Speaker notes for each slideppt/comments/modernComment_*.xml - Comments for specific slidesppt/slideLayouts/ - Layout templates for slidesppt/slideMasters/ - Master slide templatesppt/theme/ - Theme and styling informationppt/media/ - Images and other media filesWhen given an example design to emulate: Always analyze the presentation's typography and colors first using the methods below:
ppt/theme/theme1.xml for colors (<a:clrScheme>) and fonts (<a:fontScheme>)ppt/slides/slide1.xml for actual font usage (<a:rPr>) and colors<a:solidFill>, <a:srgbClr>) and font references across all XML filesWhen creating a new PowerPoint presentation from scratch, use the html2pptx workflow to convert HTML slides to PowerPoint with accurate positioning.
CRITICAL: Before creating any presentation, analyze the content and choose appropriate design elements:
Requirements:
Choosing colors creatively:
Example color palettes (use these to spark creativity - choose one, adapt it, or create your own):
Geometric Patterns:
Border & Frame Treatments:
Typography Treatments:
Chart & Data Styling:
Layout Innovations:
Background Treatments:
When creating slides with charts or tables:
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.<p>, <h1>-<h6>, <ul>, <ol> for all text contentclass="placeholder" for areas where charts/tables will be added (render with gray background for visibility)html2pptx.js library to convert HTML slides to PowerPoint and save the presentation

node scripts/validate_pptx.mjs --input output.pptx
ok: false result as a failed presentation. The validator checks ZIP readability, required PPTX parts, XML well-formedness, slide references, internal relationship targets, embedded media signatures, and duplicate slide shape ids.
If validation fails, fix/regenerate the deck and rerun the validator before continuing.python scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4Before delivering any generated or edited presentation:
node scripts/validate_pptx.mjs --input output.pptx..rels targets, missing slide parts, invalid media signatures, or duplicate slide shape ids.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.
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.python ooxml/scripts/unpack.py <office_file> <output_dir>ppt/slides/slide{N}.xml and related files)python ooxml/scripts/validate.py <dir> --original <file>python ooxml/scripts/pack.py <input_directory> <office_file>node scripts/validate_pptx.mjs --input <office_file>
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.
Extract template text AND create visual thumbnail grid:
python -m markitdown template.pptx > template-content.mdtemplate-content.md: Read the entire file to understand the contents of the template presentation. NEVER set any range limits when reading this file.python scripts/thumbnail.py template.pptxAnalyze template and save inventory to a file:
template-inventory.md containing:
# 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 ...]
Create presentation outline based on template inventory:
outline.md with content AND template mapping that leverages available designs# 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)
]
Duplicate, reorder, and delete slides using rearrange.py:
scripts/rearrange.py script to create a new presentation with slides in the desired order:
python scripts/rearrange.py template.pptx working.pptx 0,34,34,50,52
Extract ALL text using the inventory.py script:
Run inventory extraction:
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:
{
"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:
default_font_size in points extracted from layout placeholders (when available)bullet: true, level is always included (even if 0)space_before, space_after, and line_spacing in points (only included when set)color for RGB (e.g., "FF0000"), theme_color for theme colors (e.g., "DARK_1")Generate replacement text and save the data to a JSON file Based on the text inventory from the previous step:
alignment property on when "bullet": true"bold": true"bullet": true, "level": 0 (level is required when bullet is true)"alignment": "CENTER" for centered text)"font_size": 14.0, "font_name": "Lora")"color": "FF0000" for RGB or "theme_color": "DARK_1" for theme colorsreplacement-text.jsonExample paragraphs field showing proper formatting:
"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:
{
"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:
"bullet": true, "level": 0Apply replacements using the replace.py script
python scripts/replace.py working.pptx replacement-text.json output.pptx
The script will:
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")
To create visual thumbnail grids of PowerPoint slides for quick analysis and reference:
python scripts/thumbnail.py template.pptx [output_prefix]
Features:
thumbnails.jpg (or thumbnails-1.jpg, thumbnails-2.jpg, etc. for large decks)python scripts/thumbnail.py template.pptx my-grid
workspace/my-grid)--cols 4 (range: 3-6, affects slides per grid)Use cases:
Examples:
# Basic usage
python scripts/thumbnail.py presentation.pptx
# Combine options: custom name, columns
python scripts/thumbnail.py template.pptx analysis --cols 4
To visually analyze PowerPoint slides, convert them to images using a two-step process:
Convert PPTX to PDF:
soffice --headless --convert-to pdf template.pptx
Convert PDF pages to JPEG images:
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 filesExample for specific range:
pdftoppm -jpeg -r 150 -f 2 -l 5 template.pdf slide # Converts only pages 2-5
IMPORTANT: When generating code for PPTX operations:
Required dependencies (should already be installed):
pip install "markitdown[pptx]" (for text extraction from presentations)npm install -g pptxgenjs (for creating presentations via html2pptx)npm install -g playwright (for HTML rendering in html2pptx)npm install -g react-icons react react-dom (for icons)npm install -g sharp (for SVG rasterization and image processing)sudo apt-get install libreoffice (for PDF conversion)sudo apt-get install poppler-utils (for pdftoppm to convert PDF to images)pip install defusedxml (for secure XML parsing)
