Design Philosophy

Decks designed for reading and sharing , not live presentation:

• Each slide self-explanatory without verbal commentary
• Logical flow when scrolling
• All necessary context within each slide
• Optimized for social media sharing

See references/design-guidelines.md for:

• Audience-specific principles
• Visual hierarchy
• Content density guidelines
• Color and typography selection
• Font recommendations

See references/layouts.md for layout options.

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

Conflict Handling : See Step 1.3 for existing content detection and user options.

Language Handling

Detection Priority :

1. --lang flag (explicit)
2. EXTEND.md language setting
3. User's conversation language (input language)
4. Source content language

Rule : ALL responses use user's preferred language:

• Questions and confirmations
• Progress reports
• Error messages
• Completion summaries

Technical terms (style names, file paths, code) remain in English.

Workflow

Copy this checklist and check off items as you complete them:

Slide Deck Progress:
- [ ] Step 1: Setup & Analyze
  - [ ] 1.1 Load preferences
  - [ ] 1.2 Analyze content
  - [ ] 1.3 Check existing ⚠️ REQUIRED
- [ ] Step 2: Confirmation ⚠️ REQUIRED (Round 1, optional Round 2)
- [ ] Step 3: Generate outline
- [ ] Step 4: Review outline (conditional)
- [ ] Step 5: Generate prompts
- [ ] Step 6: Review prompts (conditional)
- [ ] Step 7: Generate images
- [ ] Step 8: Merge to PPTX/PDF
- [ ] Step 9: Output summary

Flow

Input → Preferences → Analyze → [Check Existing?] → Confirm (1-2 rounds) → Outline → [Review Outline?] → Prompts → [Review Prompts?] → Images → Merge → Complete

Step 1: Setup & Analyze

1.1 Load Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .baoyu-skills/baoyu-slide-deck/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md" && echo "user"

┌──────────────────────────────────────────────────┬───────────────────┐ │ Path │ Location │ ├──────────────────────────────────────────────────┼───────────────────┤ │ .baoyu-skills/baoyu-slide-deck/EXTEND.md │ Project directory │ ├──────────────────────────────────────────────────┼───────────────────┤ │ $HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md │ User home │ └──────────────────────────────────────────────────┴───────────────────┘

When EXTEND.md Found → Read, parse, output summary to user :

📋 Loaded preferences from [full path]
├─ Style: [preset/custom name]
├─ Audience: [audience or "auto-detect"]
├─ Language: [language or "auto-detect"]
└─ Review: [enabled/disabled]

When EXTEND.md Not Found → First-time setup using AskUserQuestion or proceed with defaults.

EXTEND.md Supports : Preferred style | Custom dimensions | Default audience | Language preference | Review preference

Schema: references/config/preferences-schema.md

1.2 Analyze Content

1. Save source content (if pasted, save as source.md)
   • Backup rule : If source.md exists, rename to source-backup-YYYYMMDD-HHMMSS.md
2. Follow references/analysis-framework.md for content analysis
3. Analyze content signals for style recommendations
4. Detect source language
5. Determine recommended slide count
6. Generate topic slug from content

1.3 Check Existing Content ⚠️ REQUIRED

MUST execute before proceeding to Step 2.

Use Bash to check if output directory exists:

test -d "slide-deck/{topic-slug}" && echo "exists"

If directory exists , use AskUserQuestion:

header: "Existing"
question: "Existing content found. How to proceed?"
options:
  - label: "Regenerate outline"

• If custom dimensions → Read dimension files from references/dimensions/ and combine

Generate :

1. Follow references/outline-template.md for structure
2. Build STYLE_INSTRUCTIONS from style or dimensions
3. Apply confirmed audience, language, slide count
4. Save as outline.md

After generation :

• If --outline-only, stop here
• If skip_outline_review is true → Skip Step 4, go to Step 5
• If skip_outline_review is false → Continue to Step 4

Step 4: Review Outline (Conditional)

Skip this step if user selected "No, skip outline review" in Step 2.

Purpose : Review outline structure before prompt generation.

Language : Use user's input language or saved language preference.

Display :

• Total slides: N

• Style: [preset name or "custom: texture+mood+typography+density"]

• Slide-by-slide summary table:

  #	Title	Type	Layout
  1	[title]	Cover	title-hero
  2	[title]	Content	[layout]
  3	[title]	Content	[layout]
  ...	...	...	...

    description: "Create new outline with different approach"

After response :

1. If "Edit outline first" → Inform user to edit outline.md, ask again when ready
2. If "Regenerate outline" → Back to Step 3
3. If "Yes, proceed" → Continue to Step 5

Step 5: Generate Prompts

1. Read references/base-prompt.md
2. For each slide in outline:
   • Extract STYLE_INSTRUCTIONS from outline (not from style file again)
   • Add slide-specific content
   • If Layout: specified, include layout guidance from references/layouts.md
3. Save to prompts/ directory
   • Backup rule : If prompt file exists, rename to prompts/NN-slide-{slug}-backup-YYYYMMDD-HHMMSS.md

After generation :

• If --prompts-only, stop here and output prompt summary
• If skip_prompt_review is true → Skip Step 6, go to Step 7
• If skip_prompt_review is false → Continue to Step 6

Step 6: Review Prompts (Conditional)

Skip this step if user selected "No, skip prompt review" in Step 2.

Purpose : Review prompts before image generation.

Language : Use user's input language or saved language preference.

Display :

• Total prompts: N

• Style: [preset name or custom dimensions]

• Prompt list:

  #	Filename	Slide Title
  1	01-slide-cover.md	[title]
  2	02-slide-xxx.md	[title]
  ...	...	...

• Path to prompts directory: prompts/

Use AskUserQuestion :

header: "Confirm"

    description: "Create new prompts with different approach"

After response :

1. If "Edit prompts first" → Inform user to edit prompts, ask again when ready
2. If "Regenerate prompts" → Back to Step 5
3. If "Yes, proceed" → Continue to Step 7

Step 7: Generate Images

For--images-only: Start here with existing prompts.

For--regenerate N: Only regenerate specified slide(s).

Standard flow :

1. Select available image generation skill
2. Generate session ID: slides-{topic-slug}-{timestamp}
3. For each slide:
   • Backup rule : If image file exists, rename to NN-slide-{slug}-backup-YYYYMMDD-HHMMSS.png
   • Generate image sequentially with same session ID
4. Report progress: "Generated X/N" (in user's language)
5. Auto-retry once on failure before reporting error

Step 8: 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 9: Output Summary

Language : Use user's input language or saved language preference.

Partial Workflows

Using --prompts-only

Generate outline and prompts without images:

/baoyu-slide-deck content.md --prompts-only

Output: outline.md + prompts/*.md ready for review/editing.

Using --images-only

Generate images from existing prompts (starts at Step 7):

/baoyu-slide-deck slide-deck/topic-slug/ --images-only

Prerequisites:

• prompts/ directory with slide prompt files
• outline.md with style information

Using --regenerate

Regenerate specific slides:

# Single slide
/baoyu-slide-deck slide-deck/topic-slug/ --regenerate 3

# Multiple slides
/baoyu-slide-deck slide-deck/topic-slug/ --regenerate 2,5,8

Flow:

1. Read existing prompts for specified slides
2. Regenerate images only for those slides
3. Regenerate PPTX/PDF

Slide Modification

Quick Reference

Edit Single Slide

1. Update prompt file FIRST in prompts/NN-slide-{slug}.md
2. Run: /baoyu-slide-deck <dir> --regenerate N
3. Or manually regenerate image + PDF

IMPORTANT : When updating slides, ALWAYS update the prompt file (prompts/NN-slide-{slug}.md) FIRST before regenerating. This ensures changes are documented and reproducible.

Add New Slide

1. Create prompt at position: prompts/NN-slide-{new-slug}.md
2. Generate image using same session ID
3. Renumber : Subsequent files NN+1 (slugs unchanged)
4. Update outline.md
5. Regenerate PPTX/PDF

Delete Slide

1. Remove NN-slide-{slug}.png and prompts/NN-slide-{slug}.md
2. Renumber : Subsequent files NN-1 (slugs unchanged)
3. Update outline.md
4. Regenerate PPTX/PDF

File Naming

Format: NN-slide-[slug].png

• NN: Two-digit sequence (01, 02, ...)
• slug: Kebab-case from content (2-5 words, unique)

Renumbering Rule : Only NN changes, slugs remain unchanged.

See references/modification-guide.md for complete details.

References

Notes

• Image generation: 10-30 seconds per slide
• Auto-retry once on generation failure
• Use stylized alternatives for sensitive public figures
• Maintain style consistency via session ID
• Step 2 confirmation required - do not skip (style, audience, slides, outline review, prompt review)
• Step 4 conditional - only if user requested outline review in Step 2
• Step 6 conditional - only if user requested prompt review in Step 2
