## 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.

## File Management

### Output Directory

```
slide-deck\/{topic-slug}\/
├── source-{slug}.{ext}
├── outline.md
├── prompts\/
│   └── 01-slide-cover.md, 02-slide-{slug}.md, ...
├── 01-slide-cover.png, 02-slide-{slug}.png, ...
├── {topic-slug}.pptx
└── {topic-slug}.pdf
```

**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):

```bash
# 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`)
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:

```bash
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"
    description: "Keep images, regenerate outline only"
  - label: "Regenerate images"
    description: "Keep outline, regenerate images only"
  - label: "Backup and regenerate"
    description: "Backup to {slug}-backup-{timestamp}, then regenerate all"
  - label: "Exit"
    description: "Cancel, keep existing content unchanged"
```

**Save to `analysis.md`** with:
- Topic, audience, content signals
- Recommended style (based on Auto Style Selection)
- Recommended slide count
- Language detection

### Step 2: Confirmation ⚠️ REQUIRED

**Two-round confirmation**: Round 1 always, Round 2 only if "Custom dimensions" selected.

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

  - label: "minimal"
    description: "One focus point, maximum whitespace"
  - label: "dense"
    description: "Multiple data points, compact"
```

**After Round 2**: Store custom dimensions as the style configuration.

**After Confirmation**:
1. Update `analysis.md` with confirmed preferences
2. Store `skip_outline_review` flag from Question 4
3. Store `skip_prompt_review` flag from Question 5
4. → Step 3

### Step 3: Generate Outline

Create outline using the confirmed style from Step 2.

**Style Resolution**:
- If preset selected → Read `references\/styles\/{preset}.md`
- 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] |
| ... | ... | ... | ... |
```

**Use AskUserQuestion**:
```
header: "Confirm"
question: "Ready to generate prompts?"
options:
  - label: "Yes, proceed (Recommended)"
    description: "Generate image prompts"
  - label: "Edit outline first"
    description: "I'll modify outline.md before continuing"
  - label: "Regenerate outline"
    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

**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"
question: "Ready to generate slide images?"
options:
  - label: "Yes, proceed (Recommended)"
    description: "Generate all slide images"
  - label: "Edit prompts first"
    description: "I'll modify prompts before continuing"
  - label: "Regenerate prompts"
    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. Generate each slide 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

```bash
npx -y bun ${SKILL_DIR}\/scripts\/merge-to-pptx.ts 
npx -y bun ${SKILL_DIR}\/scripts\/merge-to-pdf.ts 
```

### Step 9: Output Summary

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

```
Slide Deck Complete!

Topic: [topic]
Style: [preset name or custom dimensions]
Location: [directory path]
Slides: N total

- 01-slide-cover.png - Cover
- 02-slide-intro.png - Content
- ...
- {NN}-slide-back-cover.png - Back Cover

Outline: outline.md
PPTX: {topic-slug}.pptx
PDF: {topic-slug}.pdf
```

## 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 → 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 in `prompts\/NN-slide-{slug}.md`
2. Run: `\/baoyu-slide-deck  --regenerate N`
3. Or manually regenerate image + PDF

### 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.
