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:

Question	When to Ask
Style variant	Always (3 options + custom)
Language	Only if source ≠ user language

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:

Option	Label	Description
1	Gemini API (Recommended)	Official Google API via Python. Requires GOOGLE_API_KEY env var.
2	Gemini Web (Browser-based)	⚠️ Uses reverse-engineered web API. No API key needed but may break.

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
