## Auto Selection

Content signals determine default art + tone + layout (or preset):

| Content Signals | Recommended |
|-----------------|-------------|
| Tutorial, how-to, programming, educational | **ohmsha** preset |
| Pre-1950, classical, ancient | realistic + vintage |
| Personal story, mentor | ligne-claire + warm |
| Martial arts, wuxia | **wuxia** preset |

**When preset is recommended**: Load `references/presets/{preset}.md` and apply all special rules.

Details: [references/auto-selection.md](references/auto-selection.md)

## Script Directory

**Important**: All scripts are located in the `scripts/` subdirectory of this skill.

**Agent Execution Instructions**:
1. Determine this SKILL.md file's directory path as `SKILL_DIR`
2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
3. Replace all `${SKILL_DIR}` in this document with the actual path

**Script Reference**:
| Script | Purpose |
|--------|---------|
| `scripts/merge-to-pdf.ts` | Merge comic pages into PDF |

## File Structure

Output directory: `comic/{topic-slug}/`
- Slug: 2-4 words kebab-case from topic (e.g., `alan-turing-bio`)
- Conflict: append timestamp (e.g., `turing-story-20260118-143052`)

**Contents**:
| File | Description |
|------|-------------|
| `source-{slug}.{ext}` | Source files |
| `analysis.md` | Content analysis |
| `storyboard.md` | Storyboard with panel breakdown |
| `characters/characters.md` | Character definitions |
| `characters/characters.png` | Character reference sheet |
| `prompts/NN-{cover\|page}-[slug].md` | Generation prompts |
| `NN-{cover\|page}-[slug].png` | Generated images |
| `{topic-slug}.pdf` | Final merged PDF |

## Language Handling

**Detection Priority**:
1. `--lang` flag (explicit)
2. EXTEND.md `language` setting
3. User's conversation language
4. Source content language

**Rule**: Use user's input language or saved language preference for ALL interactions:
- Storyboard outlines and scene descriptions
- Image generation prompts
- User selection options and confirmations
- Progress updates, questions, errors, summaries

Technical terms remain in English.

### Step Summary

| Step | Action | Key Output |
|------|--------|------------|
| 1.1 | Load EXTEND.md preferences ⛔ BLOCKING if not found | Config loaded |
| 1.2 | Analyze content | `analysis.md` |
| 1.3 | Check existing directory | Handle conflicts |
| 2 | Confirm style, focus, audience, reviews | User preferences |
| 3 | Generate storyboard + characters | `storyboard.md`, `characters/` |
| 4 | Review outline (if requested) | User approval |
| 5 | Generate prompts | `prompts/*.md` |
| 6 | Review prompts (if requested) | User approval |
| **7.1** | **Generate character sheet FIRST** | `characters/characters.png` |
| **7.2** | Generate pages **with character ref** | `*.png` files |
| 8 | Merge to PDF | `{slug}.pdf` |
| 9 | Completion report | Summary |

### Step 7: Image Generation ⚠️ CRITICAL

**Character reference is MANDATORY for visual consistency.**

**7.1 Generate character sheet first**:
- **Backup rule**: If `characters/characters.png` exists, rename to `characters/characters-backup-YYYYMMDD-HHMMSS.png`
```bash
# Use Reference Sheet Prompt from characters/characters.md
npx -y bun ${SKILL_DIR}/../baoyu-image-gen/scripts/main.ts \
  --promptfiles characters/characters.md \
  --image characters/characters.png --ar 4:3
```

**Compress character sheet** (recommended):
Compress to reduce token usage when used as reference image:
- Use available image compression skill (if any)
- Or system tools: `pngquant`, `optipng`, `sips` (macOS)
- **Keep PNG format**, lossless compression preferred

**7.2 Generate each page WITH character reference**:

| Skill Capability | Strategy |
|------------------|----------|
| Supports `--ref` | Pass `characters/characters.png` with EVERY page |
| No `--ref` support | Prepend character descriptions to EVERY prompt file |

**Backup rules for page generation**:
- If prompt file exists: rename to `prompts/NN-{cover|page}-[slug]-backup-YYYYMMDD-HHMMSS.md`
- If image file exists: rename to `NN-{cover|page}-[slug]-backup-YYYYMMDD-HHMMSS.png`

```bash
# Example: ALWAYS include --ref for consistency
npx -y bun ${SKILL_DIR}/../baoyu-image-gen/scripts/main.ts \
  --promptfiles prompts/01-page-xxx.md \
  --image 01-page-xxx.png --ar 3:4 \
  --ref characters/characters.png
```

### EXTEND.md Paths ⛔ BLOCKING

**CRITICAL**: If EXTEND.md not found, MUST complete first-time setup before ANY other questions or steps. Do NOT proceed to content analysis, do NOT ask about art style, do NOT ask about tone — ONLY complete the preferences setup first.

| Path | Location |
|------|----------|
| `.baoyu-skills/baoyu-comic/EXTEND.md` | Project directory |
| `$HOME/.baoyu-skills/baoyu-comic/EXTEND.md` | User home |

| Result | Action |
|--------|--------|
| Found | Read, parse, display summary → Continue |
| Not found | ⛔ **BLOCKING**: Run first-time setup ONLY ([references/config/first-time-setup.md](references/config/first-time-setup.md)) → Complete and save EXTEND.md → Then continue |

**EXTEND.md Supports**: Watermark | Preferred art/tone/layout | Custom style definitions | Character presets | Language preference

Schema: [references/config/preferences-schema.md](references/config/preferences-schema.md)

## Page Modification

| Action | Steps |
|--------|-------|
| **Edit** | **Update prompt file FIRST** → `--regenerate N` → Regenerate PDF |
| **Add** | Create prompt at position → Generate with character ref → Renumber subsequent → Update storyboard → Regenerate PDF |
| **Delete** | Remove files → Renumber subsequent → Update storyboard → Regenerate PDF |

**IMPORTANT**: When updating pages, ALWAYS update the prompt file (`prompts/NN-{cover|page}-[slug].md`) FIRST before regenerating. This ensures changes are documented and reproducible.

## Notes

- Image generation: 10-30 seconds per page
- 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
- **Steps 4/6 conditional** - only if user requested in Step 2
- **Step 7.1 character sheet MUST be generated before pages** - ensures consistency
- **Step 7.2 EVERY page MUST reference characters** - use `--ref` or embed descriptions
- Watermark/language configured once in EXTEND.md
