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.

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

Save source content (if pasted, save as source.md)
Follow references/analysis-framework.md for content analysis
Analyze content signals for style recommendations
Detect source language
Determine recommended slide count
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:

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:

/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:

Read existing prompts for specified slides
Regenerate images only for those slides
Regenerate PPTX/PDF

Slide Modification

Quick Reference

| Action | Command | Manual Steps | |--------|---------|--------------| | Edit | --regenerate N | Update prompt → 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

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

Add New Slide

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

Delete Slide

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