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

# 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

# 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) → 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

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
