Design Philosophy

This deck is designed for reading and sharing, not live presentation:

• Each slide must be self-explanatory without verbal commentary
• Structure content for logical flow when scrolling
• Include all necessary context within each slide
• Optimize for social media sharing and offline reading

File Management

Output Directory

Each session creates an independent directory named by content slug:

slide-deck/{topic-slug}/
├── source-{slug}.{ext}    # Source files (text, images, etc.)
├── outline.md
├── outline-{style}.md     # Style variant outlines
├── prompts/
│   └── 01-slide-cover.md, 02-slide-{slug}.md, ...
├── 01-slide-cover.png, 02-slide-{slug}.png, ...
├── {topic-slug}.pptx
└── {topic-slug}.pdf

Slug Generation: 1. Extract main topic from content (2-4 words, kebab-case) 2. Example: "Introduction to Machine Learning" → intro-machine-learning

Conflict Resolution

If slide-deck/{topic-slug}/ already exists:

• Append timestamp: {topic-slug}-YYYYMMDD-HHMMSS
• Example: intro-ml exists → intro-ml-20260118-143052

Source Files

Copy all sources with naming source-{slug}.{ext}:

• source-article.md (main text content)
• source-diagram.png (image from conversation)
• source-data.xlsx (additional file)

Multiple sources supported: text, images, files from conversation.

Workflow

Step 1: Analyze Content

1. Save source content (if pasted, save as source.md) 2. Follow references/analysis-framework.md for deep content analysis 3. Determine style (use --style or auto-select from signals) 4. Detect languages (source vs. user preference) 5. Plan slide count (--slides or dynamic) 6. For academic papers (PDF with figures): Run automatic figure detection:

   npx -y bun ${SKILL_DIR}/scripts/detect-figures.ts --pdf source-paper.pdf --output figures.json

This outputs a JSON file with all detected figures/tables, their page numbers, and captions.

Step 2: Generate Outline Variants

1. Generate 3 style variant outlines based on content analysis 2. Follow references/outline-template.md for structure 3. Auto-populate IMAGE_SOURCE for academic papers:

• Read figures.json from Step 1
• Map figures to slides using rules in references/analysis-framework.md Section 8
• Automatically add // IMAGE_SOURCE blocks to appropriate slides:
• Architecture/pipeline figures → Methods slides (Source: extract)
• Results tables → Quantitative results slides (Source: extract)
• Comparison images → Qualitative results slides (Source: extract)
• Conceptual/simple diagrams → Leave for AI generation (Source: generate or omit)

4. Save as outline-{style}.md for each variant

Step 3: User Confirmation

Single AskUserQuestion with all applicable options:

After selection:

• Copy selected outline-{style}.md to outline.md
• Regenerate in different language if requested
• User may edit outline.md for fine-tuning

If --outline-only, stop here.

Step 4: Generate Prompts

1. Read references/base-prompt.md 2. Combine with style instructions from outline 3. Add slide-specific content 4. If Layout: specified in outline, include layout guidance in prompt:

• Reference layout characteristics for image composition
• Example: Layout: hub-spoke → "Central concept in middle with related items radiating outward"

5. Save to prompts/ directory

Step 5: Image Generation Method Selection

Before generating images, ask user to choose generation method:

Use AskUserQuestion with options:

Based on selection:

Option 1: Gemini API (Python)

1. Verify API key: Check GOOGLE_API_KEY or GEMINI_API_KEY environment variable 2. Run generation script:

   python ${SKILL_DIR}/scripts/generate-slides.py <slide-deck-dir> --model gemini-3-pro-image-preview

Script Features:

• Auto-installs google-genai package if missing
• Retry logic with exponential backoff (3 retries)
• Skips already-generated slides (> 10KB)
• Supports custom model via --model flag
• Outputs to slides/ subdirectory

Troubleshooting:

• If server disconnection errors occur, script auto-retries
• For persistent failures, re-run the script (it skips completed slides)
• Check API quota if many failures occur

Option 2: Gemini Web Skill

1. Consent Check: Read consent file at:

• Windows: $APPDATA/baoyu-skills/gemini-web/consent.json
• macOS: ~/Library/Application Support/baoyu-skills/gemini-web/consent.json
• Linux: ~/.local/share/baoyu-skills/gemini-web/consent.json

2. If no consent or version mismatch, display disclaimer and ask:

   ⚠️ DISCLAIMER: This uses a reverse-engineered Gemini Web API (NOT official).
   Risks: May break anytime, no support, possible account risk.

3. For each slide, run:

   npx -y bun ${GEMINI_WEB_SKILL_DIR}/scripts/main.ts \
     --promptfiles prompts/01-slide-cover.md \
     --image 01-slide-cover.png \
     --sessionId slides-{topic-slug}-{timestamp}

Where GEMINI_WEB_SKILL_DIR = path to baoyu-danger-gemini-web skill directory.

4. Proxy support: If user is in restricted network, prepend:

   HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890

Step 5.5: Process IMAGE_SOURCE (Automatic Figure Extraction)

For academic presentations, IMAGE_SOURCE metadata was auto-populated in Step 2 based on figure detection from Step 1.

Automatic Execution:

1. Parse outline to identify slides with Source: extract 2. Create figures directory: mkdir -p figures 3. For each extract slide, automatically:

• Read the Figure number, Page, and Caption from metadata
• Run figure extraction script:

     npx -y bun ${SKILL_DIR}/scripts/extract-figure.ts \
       --pdf source-paper.pdf \
       --page <page-number> \
       --output figures/figure-<N>.png

• Run template application script:

     npx -y bun ${SKILL_DIR}/scripts/apply-template.ts \
       --figure figures/figure-<N>.png \
       --title "<slide-headline>" \
       --caption "Figure <N>: <caption-text>" \
       --output <NN>-slide-<slug>.png

• Report: "Extracted: Figure N → slide NN"

4. For slides with `Source: generate` (or no IMAGE_SOURCE):

• Proceed to Step 6 for AI generation

Note: Source PDF must be saved as source-paper.pdf in output directory.

Troubleshooting:

• If figure detection missed a figure: manually add // IMAGE_SOURCE block to outline
• If wrong figure mapped: edit the Figure: and Page: values in outline
• If extraction fails: check PDF page number (1-indexed)

PyMuPDF Fallback for Page Extraction: If extract-figure.ts fails with "Image or Canvas expected" error (common with complex PDFs), use PyMuPDF:

import fitz
doc = fitz.open("source-paper.pdf")
page = doc[page_num - 1]  # 0-indexed
mat = fitz.Matrix(3, 3)  # 3x scale for high resolution
pix = page.get_pixmap(matrix=mat)
pix.save(f"extracted/page-{page_num}.png")

Then apply template using apply-template.ts.

Step 6: Generate Images

1. Use selected method from Step 5 2. Skip slides already processed in Step 5.5 (those with Source: extract) 3. Generate session ID: slides-{topic-slug}-{timestamp} 4. Generate each remaining slide with same session ID 5. Report progress: "Generated X/N" 6. Auto-retry once on generation failure

Step 7: Merge to PPTX and PDF

npx -y bun ${SKILL_DIR}/scripts/merge-to-pptx.ts <slide-deck-dir>
npx -y bun ${SKILL_DIR}/scripts/merge-to-pdf.ts <slide-deck-dir>

Step 8: Output Summary

Notes

Image Generation

• Nano Banana Pro API: Recommended. Stable, reliable, requires API key
• Gemini Web: No API key needed, but uses reverse-engineered API with account risk
• Generation time: 10-30 seconds per slide
• Auto-retry once on generation failure
• Maintain style consistency via session ID

Content Guidelines

• Use stylized alternatives for sensitive public figures
• Both methods use the same underlying Gemini model for image generation

Extension Support

Custom styles and configurations via EXTEND.md.

Check paths (priority order): 1. .paper-skills/paper-slide-deck/EXTEND.md (project) 2. ~/.paper-skills/paper-slide-deck/EXTEND.md (user)

If found, load before Step 1. Extension content overrides defaults.

Presentation Analysis Framework

Deep content analysis for effective slide deck creation.

1. Message Hierarchy

Identify the core message structure before designing slides.

Core Message (One Sentence)

• What is the single most important takeaway?
• If the audience remembers only one thing, what should it be?
• Can you state it in ≤15 words?

Supporting Points (3-5 Maximum)

• What evidence supports the core message?
• What sub-topics must be covered?
• Prioritize by audience relevance, not source order

Call-to-Action

• What should the audience DO after viewing?
• Is it clear, specific, and achievable?
• Where does it appear (slide position)?

2. Audience Decision Matrix

Audience Adaptation

3. Visual Opportunity Map

Identify which content benefits from visualization.

Content-to-Visual Mapping

Visual Priority

Rate each piece of content:

• Must Visualize: Complex data, key differentiators, memorable moments
• Should Visualize: Supporting evidence, secondary points
• Text Only: Simple statements, transitions, minor details

4. Presentation Flow

Structure for impact and retention.

Opening (First 2-3 Slides)

Middle (Content Slides)

Closing (Final 2-3 Slides)

Transitions

• Each slide should answer: "What comes next?"
• Use narrative connectors between sections
• Build logical progression, not topic jumps

5. Content Adaptation

Decide what to keep, transform, or omit.

Keep (High Value)

• Core arguments and evidence
• Unique insights or data
• Audience-relevant examples
• Memorable quotes or statistics

Simplify (Medium Value)

• Technical details → Visual summaries
• Long explanations → Bullet hierarchies
• Multiple examples → Best 1-2 examples
• Background context → Brief framing

Visualize (Transform)

• Data tables → Charts or highlighted numbers
• Process descriptions → Flow diagrams
• Comparisons in text → Side-by-side visuals
• Abstract concepts → Concrete metaphors

Omit (Low Value)

• Tangential information
• Redundant examples
• Excessive caveats
• Background the audience already knows

6. Analysis Checklist

7. Academic Presentation Analysis

For conference talks, thesis defense, and research presentations.

Paper Structure to Slide Mapping

Academic Slide Count Guidelines

Citation Handling

Inline Citations:

• Key works: "[Author et al., Year]" or "[1]"
• Include only most relevant citations on slides
• Full bibliographic details optional

Reference Slide:

• List 5-10 key references at end
• Format: [N] Author et al. "Title." Venue, Year.

Results Presentation Checklist

• [ ] Baseline comparisons clearly labeled
• [ ] Best results highlighted (bold or color)
• [ ] Statistical significance noted where applicable
• [ ] Units and metrics clearly stated
• [ ] Error bars or confidence intervals if available
• [ ] Ablation results in separate table/chart

Academic Talk Flow

1. Hook (1 slide): Problem motivation, why it matters 2. Background (1-2 slides): Essential context only 3. Approach (2-4 slides): Your method, architecture 4. Results (2-4 slides): Main experiments, comparisons 5. Analysis (1-2 slides): Ablations, insights (optional) 6. Conclusion (1 slide): Summary, contributions, future work 7. References (1 slide): Key citations

8. Automatic Figure Detection and Mapping

For academic papers, automatically detect and map figures/tables to slides.

Figure Detection Process

1. Run detection script on source PDF:

   npx -y bun ${SKILL_DIR}/scripts/detect-figures.ts --pdf source-paper.pdf --output figures.json

2. Parse detection results to identify:

• Figure numbers, pages, and captions
• Table numbers, pages, and captions
• Total figure/table count

Figure-to-Slide Mapping Rules

Automatic Mapping Algorithm

For each detected figure:
  1. Analyze caption keywords:
     - "architecture", "framework", "pipeline", "network" → Methods slide
     - "comparison", "results", "performance" → Results slide
     - "ablation", "analysis" → Analysis slide
     - "qualitative", "visual" → Qualitative Results slide

  2. Determine extraction necessity:
     - Contains numerical data (tables) → Extract
     - Contains precise diagrams (architecture) → Extract
     - Contains comparison images → Extract
     - Simple conceptual illustration → Generate

  3. Match to outline slide:
     - Find slide with matching topic
     - Add IMAGE_SOURCE metadata automatically

Mapping Confidence Levels

Figure Caption Keywords

Extract (High Priority):

• "architecture", "framework", "pipeline", "overview", "structure"
• "comparison", "results", "performance", "evaluation"
• "ablation", "analysis", "study"
• "qualitative", "visual", "segmentation", "detection"
• Table I/II/III, Table 1/2/3

Generate (Low Priority):

• "illustration", "example", "concept", "motivation"
• "schematic", "diagram" (simple ones)
• Generic workflow without specific data

Auto-Population Format

When auto-populating IMAGE_SOURCE in outline:

// IMAGE_SOURCE
Source: extract
Figure: Figure 2
Page: 4
Caption: Overview of the proposed two-stage framework
Confidence: high
Mapping: Methods slide - "architecture" keyword match

Review Checklist

After auto-detection, verify:

• [ ] All key figures detected (architecture, results tables)
• [ ] Page numbers correct
• [ ] No duplicate mappings
• [ ] Conceptual slides correctly marked as "generate"

9. Practical Implementation Notes

Lessons learned from real-world slide generation sessions.

PDF Figure Extraction

pdfjs-dist Compatibility:

• Use pdfjs-dist/legacy/build/pdf.mjs for Node.js compatibility
• The modern build requires browser APIs (DOMMatrix) not available in Node
• If extraction fails with "Image or Canvas expected", fall back to PyMuPDF

PyMuPDF (fitz) Fallback:

import fitz
doc = fitz.open("paper.pdf")
page = doc[page_num - 1]  # 0-indexed
mat = fitz.Matrix(3, 3)   # 3x scale for 4K quality
pix = page.get_pixmap(matrix=mat)
pix.save("output.png")

PyMuPDF is more reliable for complex PDFs with embedded images.

Gemini API Image Generation

Model: gemini-3-pro-image-preview

Config:

config=types.GenerateContentConfig(
    image_config=types.ImageConfig(
        aspect_ratio="16:9",
        image_size="4K"
    )
)

Response Handling:

• Image data is returned as raw bytes in part.inline_data.data
• Do NOT base64 decode - write bytes directly to file
• MIME type is image/jpeg even when requesting PNG output

Network Issues:

• Server disconnections are common for large image generation
• Implement retry logic with exponential backoff (3 retries recommended)
• Wait 5-15 seconds between retries

Optimization:

• Skip already-generated slides (check file size > 10KB)
• Run generation script multiple times if failures occur
• Script is idempotent - safe to re-run

Common Issues and Solutions

Create a presentation slide image following these guidelines:

Image Specifications

• Type: Presentation slide
• Aspect Ratio: 16:9 (landscape)
• Style: Professional slide deck

Core Persona: The Architect

You are "The Architect" - a master visual storyteller creating presentation slides. Your slides:

• Tell a visual story that complements the narrative
• Use bold, confident visual language
• Balance information density with visual clarity
• Create memorable, impactful visuals

Core Principles

• Hand-drawn quality throughout - NO realistic or photographic elements
• If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
• NO slide numbers, page numbers, footers, headers, or logos
• Clean, uncluttered layouts with clear visual hierarchy
• Each slide conveys ONE clear message

Academic Exception (for academic-paper style only)

When style is academic-paper, override these principles:

• Precise, clean diagrams ARE acceptable (not hand-drawn)
• Chart and graph rendering should be accurate and professional
• Mathematical notation and equations should be properly formatted
• Allow citation markers like "[Author et al., 2024]" or "[1]"
• Tables should have clean borders and proper alignment
• Axis labels, legends, and data annotations are required on all charts
• Figure captions in format "Figure N: [Description]" are encouraged

Text Style (CRITICAL)

• ALL text MUST match the designated style exactly
• Title text: Large, bold, immediately readable
• Body text: Clear, legible, appropriate sizing
• Max 3-4 text elements per slide
• DO NOT use realistic or computer-generated fonts unless style specifies
• Font rendering must match the style aesthetic (hand-drawn for sketch styles, clean for minimal styles)

Layout Principles

• Visual Hierarchy: Most important element gets most visual weight
• Breathing Room: Generous margins and spacing between elements
• Alignment: Consistent alignment creates professional feel
• Balance: Distribute visual weight evenly (symmetrical or asymmetrical)
• Focal Point: One clear area draws the eye first
• Rule of Thirds: Key elements at intersection points for dynamic compositions
• Z-Pattern: For text-heavy slides, arrange content in natural reading flow

Language

• Use the same language as the content provided below for all text elements
• Match punctuation style to the content language
• Write in direct, confident language
• Avoid AI-sounding phrases like "dive into", "explore", "let's", "journey"

Content & Style Rules

Guidelines for slide deck content quality and style consistency.

Content Rules

1. Respect Reader Attention

• Each slide should communicate ONE main idea
• Remove redundant information
• Prioritize clarity over comprehensiveness

2. Data Traceability

• All statistics must include source attribution
• Cite sources directly on slides with data
• Use specific numbers over vague claims

3. Self-Contained Prompts

• Every detail must be in the image prompt
• No external references (e.g., "like slide 2")
• Include all colors, layouts, and content explicitly

4. No Placeholders

• Every element must be fully specified
• No "[insert data here]" or "TBD"
• All text content finalized before generation

Style Rules

1. Narrative Headlines

Headlines tell the story, not label the content.

2. Avoid AI Clichés

Remove these patterns:

• "Dive into", "explore", "journey"
• "Let's look at", "let me show you"
• "Exciting", "amazing", "revolutionary"
• "In conclusion", "to summarize"

3. Meaningful Back Cover

Not just "Thank you" or "Questions?"

Include one of:

• Clear call-to-action
• Memorable key takeaway
• Thought-provoking closing statement
• Contact information with purpose

4. Consistent Visual Language

Throughout the deck:

• Same icon style
• Same color usage patterns
• Same layout grid system
• Same typography hierarchy

Implementation Notes

Canvas Setup (Node.js)

import { createCanvas, loadImage } from 'canvas';

const WIDTH = 1920;
const HEIGHT = 1080;

const canvas = createCanvas(WIDTH, HEIGHT);
const ctx = canvas.getContext('2d');

// Background
ctx.fillStyle = '#FFFFFF';
ctx.fillRect(0, 0, WIDTH, HEIGHT);

Title Rendering

ctx.fillStyle = '#1E3A5F';
ctx.font = 'bold 48px Arial, Helvetica, sans-serif';
ctx.textAlign = 'center';
ctx.textBaseline = 'middle';
ctx.fillText(title, WIDTH / 2, 80);

Figure Placement

// Load and scale figure
const figure = await loadImage(figurePath);
const maxWidth = WIDTH * 0.85;
const maxHeight = HEIGHT * 0.70;

const scale = Math.min(maxWidth / figure.width, maxHeight / figure.height);
const scaledWidth = figure.width * scale;
const scaledHeight = figure.height * scale;

// Center position
const x = (WIDTH - scaledWidth) / 2;
const y = (HEIGHT - scaledHeight) / 2;

// Draw shadow
ctx.shadowColor = 'rgba(0,0,0,0.1)';
ctx.shadowBlur = 12;
ctx.shadowOffsetY = 4;

// Draw border
ctx.strokeStyle = '#E5E7EB';
ctx.lineWidth = 1;
ctx.strokeRect(x - 20, y - 20, scaledWidth + 40, scaledHeight + 40);

// Draw figure
ctx.drawImage(figure, x, y, scaledWidth, scaledHeight);

Caption Rendering

ctx.fillStyle = '#6B7280';
ctx.font = 'italic 24px Arial, Helvetica, sans-serif';

Regenerate a specific slide with modified content:

1. Identify slide to edit (e.g., 03-slide-key-findings.png) 2. Update prompt in prompts/03-slide-key-findings.md 3. If content changes significantly, update slug in filename 4. Regenerate image using same session ID 5. Regenerate PPTX and PDF

Add New Slide

Insert a new slide at specified position:

1. Specify insertion position (e.g., after slide 3) 2. Create new prompt with appropriate slug (e.g., 04-slide-new-section.md) 3. Generate new slide image 4. Renumber files: All subsequent slides increment NN by 1

• 04-slide-conclusion.png → 05-slide-conclusion.png
• Slugs remain unchanged

5. Update outline.md with new slide entry 6. Regenerate PPTX and PDF

Delete Slide

Remove a slide and renumber:

1. Identify slide to delete (e.g., 03-slide-key-findings.png) 2. Remove image file and prompt file 3. Renumber files: All subsequent slides decrement NN by 1

• 04-slide-conclusion.png → 03-slide-conclusion.png
• Slugs remain unchanged

4. Update outline.md to remove slide entry 5. Regenerate PPTX and PDF

File Naming Convention

Files use meaningful slugs for better readability:

NN-slide-[slug].png
NN-slide-[slug].md (in prompts/)

Examples:

• 01-slide-cover.png
• 02-slide-problem-statement.png
• 03-slide-key-findings.png
• 04-slide-back-cover.png

Slug Rules

Renumbering Rules

Important: Slugs remain unchanged during renumbering. Only the NN prefix changes.

Image Source Metadata (Automatic Figure Extraction)

For academic presentations, IMAGE_SOURCE metadata is automatically populated based on figure detection.

Auto-Population Process

1. Figure Detection: detect-figures.ts scans PDF and outputs figures.json 2. Mapping Algorithm: Agent maps figures to slides using caption keywords:

• "architecture", "framework", "pipeline" → Methods slides
• "comparison", "results", "performance" → Results slides (quantitative)
• "qualitative", "visual", "segmentation" → Results slides (qualitative)
• Table I/II/III → Quantitative results slides

3. Auto-Insert: // IMAGE_SOURCE blocks added to outline during generation

IMAGE_SOURCE Format

// IMAGE_SOURCE
Source: generate | extract
Figure: [Figure/Table number from paper, e.g., "Figure 2", "Table 1"]
Page: [PDF page number, 1-indexed]
Caption: [Figure caption for container template]

IMAGE_SOURCE Values

Auto-Mapping Rules

Manual Override

To override auto-detection, manually edit the // IMAGE_SOURCE block in outline:

// IMAGE_SOURCE
Source: extract    # Change to 'generate' if needed
Figure: Figure 3   # Correct figure number if wrong
Page: 5            # Correct page number if wrong
Caption: Corrected caption text

Section Dividers

Use --- (horizontal rule) between:

• Header metadata and STYLE_INSTRUCTIONS
• STYLE_INSTRUCTIONS and first slide
• Each slide entry

Slide Numbering

• Cover is always Slide 1
• Content slides use sequential numbers
• Back Cover is always final slide (N)
• Filename prefix matches slide position: 01-, 02-, etc.

Filename Slugs

Generate meaningful slugs from slide content:

Slug rules:

• Kebab-case (lowercase, hyphens)
• Derived from headline or main topic
• Maximum 30 characters
• Unique within deck
