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.

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)

Check EXTEND.md existence (priority order):

bash
# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-slide-deck/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-slide-deck/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md" && echo "user"

powershell
# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-slide-deck/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-skills/baoyu-slide-deck/EXTEND.md") { "xdg" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md") { "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

1. Follow references/analysis-framework.md for content analysis
2. Analyze content signals for style recommendations
3. Detect source language
4. Determine recommended slide count
5. 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:

• 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] |

    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

1. 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] |

    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

1. Report progress: "Generated X/N" (in user's language)
2. Auto-retry once on failure before reporting error

Step 8: Merge to PPTX and PDF

bash
${BUN_X} {baseDir}/scripts/merge-to-pptx.ts <slide-deck-dir>
${BUN_X} {baseDir}/scripts/merge-to-pdf.ts <slide-deck-dir>

Step 9: Output Summary

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

Partial Workflows

| Option | Workflow | |--------|----------| | --outline-only | Steps 1-3 only (stop after outline) | | --prompts-only | Steps 1-5 (generate prompts, skip images) | | --images-only | Skip to Step 7 (requires existing prompts/) | | --regenerate N | Regenerate specific slide(s) only |

Using --prompts-only

Generate outline and prompts without images:

bash
/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):

bash
/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:

bash
# 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

| Action | Command | Manual Steps | |--------|---------|--------------| | Edit | --regenerate N | Update prompt file FIRST → Regenerate image → Regenerate PDF | | Add | Manual | Create prompt → Generate image → Renumber subsequent → Update outline → Regenerate PDF | | Delete | Manual | Remove files → Renumber subsequent → Update outline → Regenerate PDF |

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.

| File | Content | |------|---------| | references/analysis-framework.md | Content analysis for presentations | | references/outline-template.md | Outline structure and format | | references/modification-guide.md | Edit, add, delete slide workflows | | references/content-rules.md | Content and style guidelines | | references/design-guidelines.md | Audience, typography, colors, visual elements | | references/layouts.md | Layout options and selection tips | | references/base-prompt.md | Base prompt for image generation | | references/dimensions/*.md | Dimension specifications (texture, mood, typography, density) | | references/dimensions/presets.md | Preset → dimension mapping | | references/styles/<style>.md | Full style specifications (legacy) | | references/config/preferences-schema.md | EXTEND.md structure |

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
