Personal story, mentor	ligne-claire + warm
Martial arts, wuxia	wuxia preset

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 {baseDir}
2. Script path = {baseDir}/scripts/<script-name>.ts
3. Replace all {baseDir} in this document with the actual path
4. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun

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 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
• Invoke an installed image generation skill such as baoyu-imagine
• Read that skill's SKILL.md and follow its documented interface rather than calling its scripts directly
• Use characters/characters.md as the prompt-file input
• Save output to characters/characters.png
• Use aspect ratio 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
• Invoke the installed image generation skill for each page
• Use prompts/01-page-xxx.md as the prompt-file input
• Save output to 01-page-xxx.png
• Use aspect ratio 3:4
• If the chosen skill supports reference images, pass characters/characters.png as --ref

Full workflow details: references/workflow.md

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
