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
npx -y bun ${SKILL_DIR}/../canghe-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
npx -y bun ${SKILL_DIR}/../canghe-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 |
|---|
.canghe-skills/canghe-comic/EXTEND.md | Project directory |
$HOME/.canghe-skills/canghe-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) → Complete and save EXTEND.md → Then continue |
EXTEND.md Supports: Watermark | Preferred art/tone/layout | Custom style definitions | Character presets | Language preference

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
