-### Step 5: Check README Updates
+### Step 5: Group Changes by Skill/Module
 
-**IMPORTANT**: Before updating version file, check if README needs updates.
+Analyze commits since last tag and group by affected skill/module:
 
-1. **Scan for README files**: `README*.md` in project root
-2. **For each skill/feature changed**, check if README documentation matches:
-   - Options/flags documented correctly
-   - Usage examples reflect current syntax
-   - Feature descriptions are accurate
-3. **If README is outdated**:
-   - Update README.md (and README.zh.md if exists) to reflect changes
-   - Include in release commit
+1. **Identify changed files** per commit
+2. **Group by skill/module**:
+   - `skills/<skill-name>/*` → Group under that skill
+   - Root files (CLAUDE.md, etc.) → Group as "project"
+   - Multiple skills in one commit → Split into multiple groups
+3. **For each group**, identify related README updates needed
+
+**Example Grouping**:
+```
+baoyu-cover-image:
+  - feat: add new style options
+  - fix: handle transparent backgrounds
+  → README updates: options table
+
+baoyu-comic:
+  - refactor: improve panel layout algorithm
+  → No README updates needed
+
+project:
+  - docs: update CLAUDE.md architecture section
+```
+
+### Step 6: Commit Each Skill/Module Separately
+
+For each skill/module group (in order of changes):
+
+1. **Check README updates needed**:
+   - Scan `README*.md` for mentions of this skill/module
+   - Verify options/flags documented correctly
+   - Update usage examples if syntax changed
+   - Update feature descriptions if behavior changed
+
+2. **Stage and commit**:
+   ```bash
+   git add skills/<skill-name>/*
+   git add README.md README.zh.md  # If updated for this skill
+   git commit -m "<type>(<skill-name>): <meaningful description>"

+
+3. **Commit message format**:
+   - Use conventional commit format: `<type>(<scope>): <description>`
+   - `<type>`: feat, fix, refactor, docs, perf, etc.
+   - `<scope>`: skill name or "project"
+   - `<description>`: Clear, meaningful description of changes

+**Example Commits**:
+```bash
+git commit -m "feat(baoyu-cover-image): add watercolor and minimalist styles"

-## File Management
-
-### Output Directory
-
-Each session creates an independent directory named by content slug:
-
-```
-illustrations/{topic-slug}/
-├── source-{slug}.{ext}    # Source files (text, images, etc.)
-├── outline.md
-├── outline-{style}.md     # Style variant outlines
-├── prompts/
-│   ├── illustration-concept-a.md
-│   ├── illustration-concept-b.md
-│   └── ...
-├── illustration-concept-a.png
-├── illustration-concept-b.png
-└── ...
-```
-
-**Slug Generation**:
-1. Extract main topic from content (2-4 words, kebab-case)
-2. Example: "The Future of AI" → `future-of-ai`
-
-### Conflict Resolution
-
-If `illustrations/{topic-slug}/` already exists:
-- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
-- Example: `ai-future` exists → `ai-future-20260118-143052`
-
-### Source Files
-
-Copy all sources with naming `source-{slug}.{ext}`:
-- `source-article.md` (main text content)
-- `source-photo.jpg` (image from conversation)
-- `source-reference.pdf` (additional file)
-
-Multiple sources supported: text, images, files from conversation.
+See [references/styles.md](references/styles.md) for Core Styles, full gallery, and Type × Style compatibility.
 
 ## Workflow
 
-### Step 1: Analyze Content & Select Style
+```
+- [ ] Step 1: Pre-check (EXTEND.md, references, config)
+- [ ] Step 2: Analyze content
+- [ ] Step 3: Confirm settings (AskUserQuestion)
+- [ ] Step 4: Generate outline
+- [ ] Step 5: Generate images
+- [ ] Step 6: Finalize
+```
 
-1. Read article content
-2. If `--style` specified, use that style
-3. Otherwise, scan for style signals and auto-select
-4. **Language detection**:
-   - Detect **source language** from article content
-   - Detect **user language** from conversation context
-   - Note if source_language ≠ user_language (will ask in Step 4)
-5. Extract key information:
-   - Main topic and themes
-   - Core messages per section
-   - Abstract concepts needing visualization
+### Step 1: Pre-check
 
-### Step 2: Identify Illustration Positions
+**1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING**
 
-**Three Purposes of Illustrations**:
-1. **Information Supplement**: Help understand abstract concepts
-2. **Concept Visualization**: Transform abstract ideas into concrete visuals
-3. **Imagination Guidance**: Create atmosphere, enhance reading experience
+```bash
+test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"
+test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"
+```
 
-**Content Suitable for Illustrations**:
-- Abstract concepts needing visualization
-- Processes/steps needing diagrams
-- Comparisons needing visual representation
-- Core arguments needing reinforcement
-- Scenarios needing imagination guidance
+| Result | Action |
+|--------|--------|
+| Found | Read, parse, display summary |
+| Not found | ⛔ Run [first-time-setup](references/config/first-time-setup.md) |
 
-**Illustration Count**:
-- Consider at least 1 image per major section
-- Prioritize core arguments and abstract concepts
-- **Principle: More is better than fewer**
+Full procedures: [references/workflow.md](references/workflow.md#step-1-pre-check)
 
-### Step 3: Generate Illustration Plan
+### Step 2: Analyze
 
-```markdown
-# Illustration Plan
+| Analysis | Output |
+|----------|--------|
+| Content type | Technical / Tutorial / Methodology / Narrative |
+| Purpose | information / visualization / imagination |
+| Core arguments | 2-5 main points |
+| Positions | Where illustrations add value |
 
-**Article**: [article path]
-**Style**: [selected style]
-**Illustration Count**: N images
+**CRITICAL**: Metaphors → visualize underlying concept, NOT literal image.
 
----
+Full procedures: [references/workflow.md](references/workflow.md#step-2-setup--analyze)
 
+### Step 3: Confirm Settings ⚠️
+
+**ONE AskUserQuestion, max 4 Qs. Q1-Q3 REQUIRED.**
+
+| Q | Options |
+|---|---------|
+| **Q1: Type** | [Recommended], infographic, scene, flowchart, comparison, framework, timeline, mixed |
+| **Q2: Density** | minimal (1-2), balanced (3-5), per-section (Recommended), rich (6+) |
+| **Q3: Style** | [Recommended], minimal-flat, sci-fi, hand-drawn, editorial, scene, Other |
+| Q4: Language | When article language ≠ EXTEND.md setting |
+
+Full procedures: [references/workflow.md](references/workflow.md#step-3-confirm-settings-)
+
+### Step 4: Generate Outline
+
+Save `outline.md` with frontmatter (type, density, style, image_count) and entries:
+
+```yaml
 ## Illustration 1
-
-**Insert Position**: [section name] / [paragraph description]
-**Purpose**: [why illustration needed here]
-**Visual Content**: [what the image should show]
-**Filename**: illustration-[slug].png
-
----
-
-## Illustration 2
-...
+**Position**: [section/paragraph]
+**Purpose**: [why]
+**Visual Content**: [what]
+**Filename**: 01-infographic-concept-name.png
 ```
 
-### Step 4: Review & Confirm
+Full template: [references/workflow.md](references/workflow.md#step-4-generate-outline)
 
-**Purpose**: Let user confirm all options in a single step before image generation.
+### Step 5: Generate Images
 
-**IMPORTANT**: Present ALL options in a single confirmation step using AskUserQuestion. Do NOT interrupt workflow with multiple separate confirmations.
+1. Create prompts per [references/prompt-construction.md](references/prompt-construction.md)
+2. Select generation skill from available skills
+3. Process references (`direct`/`style`/`palette`)
+4. Apply watermark if EXTEND.md enabled
+5. Generate sequentially, retry once on failure
 
-1. **Generate 3 style variants**:
-   - Analyze content to select 3 most suitable styles
-   - Generate complete illustration plan for each style variant
-   - Save as `outline-{style}.md` (e.g., `outline-notion.md`, `outline-tech.md`, `outline-warm.md`)
+Full procedures: [references/workflow.md](references/workflow.md#step-5-generate-images)
 
-2. **Determine which questions to ask**:
+### Step 6: Finalize
 
-   | Question | When to Ask |
-   |----------|-------------|
-   | Style variant | Always (required) |
-   | Language | Only if `source_language ≠ user_language` |
-
-3. **Present options** (use AskUserQuestion with all applicable questions):
-
-   **Question 1 (Style)** - always:
-   - Style A (recommended): [style name] - [brief description]
-   - Style B: [style name] - [brief description]
-   - Style C: [style name] - [brief description]
-   - Custom: Provide custom style reference
-
-   **Question 2 (Language)** - only if source ≠ user language:
-   - [Source language] (matches article language)
-   - [User language] (your preference)
-
-   **Language handling**:
-   - If source language = user language: Just inform user (e.g., "Prompts will be in Chinese")
-   - If different: Ask which language to use for prompts
-
-4. **Apply selection**:
-   - Copy selected `outline-{style}.md` to `outline.md`
-   - If custom style provided, generate new plan with that style
-   - If different language selected, regenerate outline in that language
-   - User may edit `outline.md` directly for fine-tuning
-   - If modified, reload plan before proceeding
-
-5. **Proceed only after explicit user confirmation**
-
-### Step 5: Create Prompt Files
-
-Save prompts to `prompts/` directory with style-specific details.
-
-**All prompts are written in the user's confirmed language preference.**
-
-**Prompt Format**:
-
-```markdown
-Illustration theme: [concept in 2-3 words]
-Style: [style name]
-
-Visual composition:
-- Main visual: [description matching style]
-- Layout: [element positioning]
-- Decorative elements: [style-appropriate decorations]
-
-Color scheme:
-- Primary: [style primary color]
-- Background: [style background color]
-- Accent: [style accent color]
-
-Text content (if any):
-- [Any labels or captions in content language]
-
-Style notes: [specific style characteristics]
-```
-
-### Step 6: Generate Images
-
-**Image Generation Skill Selection**:
-1. Check available image generation skills
-2. If multiple skills available, ask user to choose
-
-**Generation Flow**:
-1. Call selected image generation skill with prompt file and output path
-2. Generate images sequentially
-3. After each image, output progress: "Generated X/N"
-4. On failure, auto-retry once
-5. If retry fails, log reason, continue to next
-
-### Step 7: Update Article
-
-Insert generated images at corresponding positions:
-
-```markdown
-![illustration description]([article-name]/illustrations/illustration-[slug].png)
-```
-
-**Insertion Rules**:
-- Insert image after corresponding paragraph
-- Leave one blank line before and after image
-- Alt text uses concise description in article's language
-
-### Step 8: Output Summary
+Insert `![description](path/NN-{type}-{slug}.png)` after paragraphs.
 
 ```
 Article Illustration Complete!
-
-Article: [article path]
-Style: [style name]
-Generated: X/N images successful
-
-Illustration Positions:
-- illustration-xxx.png → After section "Section Name"
-- illustration-yyy.png → After section "Another Section"
-...
-
-[If any failures]
-Failed:
-- illustration-zzz.png: [failure reason]
+Article: [path] | Type: [type] | Density: [level] | Style: [style]
+Images: X/N generated
 ```
 
-## Illustration Modification
+## Output Directory
 
-Support for modifying individual illustrations after initial generation.
-
-### Edit Single Illustration
-
-Regenerate a specific illustration with modified prompt:
-
-1. Identify illustration to edit (e.g., `illustration-concept-overview.png`)
-2. Update prompt in `prompts/illustration-concept-overview.md` if needed
-3. If content changes significantly, update slug in filename
-4. Regenerate image
-5. Update article if image reference changed
-
-### Add New Illustration
-
-Add a new illustration to the article:
-
-1. Identify insertion position in article
-2. Create new prompt with appropriate slug (e.g., `illustration-new-concept.md`)
-3. Generate new illustration image
-4. Update `outline.md` with new illustration entry
-5. Insert image reference in article at the specified position
-
-### Delete Illustration
-
-Remove an illustration from the article:
-
-1. Identify illustration to delete (e.g., `illustration-concept-overview.png`)
-2. Remove image file and prompt file

-- `illustration-workflow-diagram.png`
-- `illustration-key-benefits.png`
+**Slug**: 2-4 words, kebab-case. **Conflict**: append `-YYYYMMDD-HHMMSS`.
 
-**Slug rules**:
-- Derived from illustration purpose/content (kebab-case)
-- Must be unique within the article
-- When content changes significantly, update slug accordingly
+## Modification
+
+| Action | Steps |
+|--------|-------|
+| Edit | Update prompt → Regenerate → Update reference |
+| Add | Position → Prompt → Generate → Update outline → Insert |
+| Delete | Delete files → Remove reference → Update outline |
 
 ## References
 
 | File | Content |
 |------|---------|
-| `references/styles/<style>.md` | Full style specifications with colors, elements, rules |
-
-## Notes
-
-- Illustrations serve the content: supplement information, visualize concepts
-- Maintain selected style consistency across all illustrations in one article
-- Image generation typically takes 10-30 seconds per image
-- Sensitive figures should use cartoon alternatives
-- Prompts written in user's confirmed language preference
-- Illustration text (labels, captions) should match article language
-

+---
+
+# First-Time Setup
+
+## Overview
+
+When no EXTEND.md is found, guide user through preference setup.
+
+**⛔ BLOCKING OPERATION**: This setup MUST complete before ANY other workflow steps. Do NOT:
+- Ask about reference images
+- Ask about content/article
+- Ask about type or style preferences
+- Proceed to content analysis
+
+ONLY ask the questions in this setup flow, save EXTEND.md, then continue.
+
+## Setup Flow
+
+```
+No EXTEND.md found
+        │
+        ▼
+┌─────────────────────┐
+│ AskUserQuestion     │
+│ (all questions)     │
+└─────────────────────┘
+        │
+        ▼
+┌─────────────────────┐
+│ Create EXTEND.md    │
+└─────────────────────┘
+        │
+        ▼
+    Continue to Step 1
+```
+
+## Questions
+
+**Language**: Use user's input language or preferred language for all questions. Do not always use English.
+
+Use single AskUserQuestion with multiple questions (AskUserQuestion auto-adds "Other" option):
+
+### Question 1: Watermark
+
+```
+header: "Watermark"
+question: "Watermark text for generated illustrations? Type your watermark content (e.g., name, @handle)"
+options:
+  - label: "No watermark (Recommended)"
+    description: "No watermark, can enable later in EXTEND.md"
+```
+
+Position defaults to bottom-right.
+
+### Question 2: Preferred Style
+
+```
+header: "Style"
+question: "Default illustration style preference? Or type another style name or your custom style"
+options:
+  - label: "None (Recommended)"
+    description: "Auto-select based on content analysis"
+  - label: "notion"
+    description: "Minimalist hand-drawn line art"
+  - label: "warm"
+    description: "Friendly, approachable, personal"
+```
+
+### Question 3: Save Location
+
+```
+header: "Save"
+question: "Where to save preferences?"
+options:
+  - label: "Project"
+    description: ".baoyu-skills/ (this project only)"
+  - label: "User"
+    description: "~/.baoyu-skills/ (all projects)"
+```
+
+## Save Locations
+
+| Choice | Path | Scope |
+|--------|------|-------|
+| Project | `.baoyu-skills/baoyu-article-illustrator/EXTEND.md` | Current project |
+| User | `~/.baoyu-skills/baoyu-article-illustrator/EXTEND.md` | All projects |
+
+## After Setup
+
+1. Create directory if needed
+2. Write EXTEND.md with frontmatter
+3. Confirm: "Preferences saved to [path]"
+4. Continue to Step 1
+
+## EXTEND.md Template
+
+```yaml
+---
+version: 1
+watermark:
+  enabled: [true/false]
+  content: "[user input or empty]"
+  position: bottom-right
+  opacity: 0.7
+preferred_style:
+  name: [selected style or null]
+  description: ""
+language: null
+custom_styles: []
+---
+```
+
+## Modifying Preferences Later
+
+Users can edit EXTEND.md directly or run setup again:
+- Delete EXTEND.md to trigger setup
+- Edit YAML frontmatter for quick changes
+- Full schema: `config/preferences-schema.md`

+# Prompt Construction
+
+## Prompt File Format
+
+Each prompt file uses YAML frontmatter + content:
+
+```yaml
+---
+illustration_id: 01
+type: infographic
+style: blueprint
+references:                    # ⚠️ ONLY if files EXIST in references/ directory
+  - ref_id: 01
+    filename: 01-ref-diagram.png
+    usage: direct              # direct | style | palette
+---
+
+[Type-specific template content below...]
+```
+
+**⚠️ CRITICAL - When to include `references` field**:
+
+| Situation | Action |
+|-----------|--------|
+| Reference file saved to `references/` | Include in frontmatter ✓ |
+| Style extracted verbally (no file) | DO NOT include in frontmatter, append to prompt body instead |
+| File path in frontmatter but file doesn't exist | ERROR - remove references field |
+
+**Reference Usage Types** (only when file exists):
+
+| Usage | Description | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Primary visual reference | Pass to `--ref` parameter |
+| `style` | Style characteristics only | Describe style in prompt text |
+| `palette` | Color palette extraction | Include colors in prompt |
+
+**If no reference file but style/palette extracted verbally**, append directly to prompt body:
+```
+COLORS (from reference):
+- Primary: #E8756D coral
+- Secondary: #7ECFC0 mint
+...
+
+STYLE (from reference):
+- Clean lines, minimal shadows
+- Gradient backgrounds
+...
+```
+
+---
+
+## Default Composition Requirements
+
+**Apply to ALL prompts by default**:
+
+| Requirement | Description |
+|-------------|-------------|
+| **Clean composition** | Simple layouts, no visual clutter |
+| **White space** | Generous margins, breathing room around elements |
+| **No complex backgrounds** | Solid colors or subtle gradients only, avoid busy textures |
+| **Centered or content-appropriate** | Main visual elements centered or positioned by content needs |
+| **Matching graphics** | Use graphic elements that align with content theme |
+| **Highlight core info** | White space draws attention to key information |
+
+**Add to ALL prompts**:
+> Clean composition with generous white space. Simple or no background. Main elements centered or positioned by content needs.
+
+---
+
+## Character Rendering
+
+When depicting people:
+
+| Guideline | Description |
+|-----------|-------------|
+| **Style** | Simplified cartoon silhouettes or symbolic expressions |
+| **Avoid** | Realistic human portrayals, detailed faces |
+| **Diversity** | Varied body types when showing multiple people |
+| **Emotion** | Express through posture and simple gestures |
+
+**Add to ALL prompts with human figures**:
+> Human figures: simplified stylized silhouettes or symbolic representations, not photorealistic.
+
+---
+
+## Text in Illustrations
+
+| Element | Guideline |
+|---------|-----------|
+| **Size** | Large, prominent, immediately readable |
+| **Style** | Handwritten fonts preferred for warmth |
+| **Content** | Concise keywords and core concepts only |
+| **Language** | Match article language |
+
+**Add to prompts with text**:
+> Text should be large and prominent with handwritten-style fonts. Keep minimal, focus on keywords.
+
+---
+
+## Principles
+
+Good prompts must include:
+
+1. **Layout Structure First**: Describe composition, zones, flow direction
+2. **Specific Data/Labels**: Use actual numbers, terms from article
+3. **Visual Relationships**: How elements connect
+4. **Semantic Colors**: Meaning-based color choices (red=warning, green=efficient)
+5. **Style Characteristics**: Line treatment, texture, mood
+6. **Aspect Ratio**: End with ratio and complexity level
+
+## Type-Specific Templates

+# Detailed Workflow Procedures
+
+## Step 1: Pre-check
+
+### 1.0 Detect & Save Reference Images ⚠️ REQUIRED if images provided
+
+Check if user provided reference images. Handle based on input type:
+
+| Input Type | Action |
+|------------|--------|
+| Image file path provided | Copy to `references/` subdirectory → can use `--ref` |
+| Image in conversation (no path) | **ASK user for file path** with AskUserQuestion |
+| User can't provide path | Extract style/palette verbally → append to prompts (NO frontmatter references) |
+
+**CRITICAL**: Only add `references` to prompt frontmatter if files are ACTUALLY SAVED to `references/` directory.
+
+**If user provides file path**:
+1. Copy to `references/NN-ref-{slug}.png`
+2. Create description: `references/NN-ref-{slug}.md`
+3. Verify files exist before proceeding
+
+**If user can't provide path** (extracted verbally):
+1. Analyze image visually, extract: colors, style, composition
+2. Create `references/extracted-style.md` with extracted info
+3. DO NOT add `references` to prompt frontmatter
+4. Instead, append extracted style/colors directly to prompt text
+
+**Description File Format** (only when file saved):
+```yaml
+---
+ref_id: NN
+filename: NN-ref-{slug}.png
+---
+[User's description or auto-generated description]
+```
+
+**Verification** (only for saved files):
+```
+Reference Images Saved:
+- 01-ref-{slug}.png ✓ (can use --ref)
+- 02-ref-{slug}.png ✓ (can use --ref)
+```
+
+**Or for extracted style**:
+```
+Reference Style Extracted (no file):
+- Colors: #E8756D coral, #7ECFC0 mint...
+- Style: minimal flat vector, clean lines...

+### 1.1 Determine Input Type
+
+| Input | Output Directory | Next |
+|-------|------------------|------|
+| File path | Ask user (1.2) | → 1.2 |
+| Pasted content | `illustrations/{topic-slug}/` | → 1.4 |
+
+**Backup rule for pasted content**: If `source.md` exists in target directory, rename to `source-backup-YYYYMMDD-HHMMSS.md` before saving.
+
+### 1.2-1.4 Configuration (file path input only)
+
+Check preferences and existing state, then ask ALL needed questions in ONE AskUserQuestion call (max 4 questions).
+
+**Questions to include** (skip if preference exists or not applicable):
+
+| Question | When to Ask | Options |
+|----------|-------------|---------|
+| Output directory | No `default_output_dir` in EXTEND.md | `{article-dir}/`, `{article-dir}/imgs/` (Recommended), `{article-dir}/illustrations/`, `illustrations/{topic-slug}/` |
+| Existing images | Target dir has `.png/.jpg/.webp` files | `supplement`, `overwrite`, `regenerate` |
+| Article update | Always (file path input) | `update`, `copy` |
+
+**Preference Values** (if configured, skip asking):
+
+| `default_output_dir` | Path |
+|----------------------|------|
+| `same-dir` | `{article-dir}/` |
+| `imgs-subdir` | `{article-dir}/imgs/` |
+| `illustrations-subdir` | `{article-dir}/illustrations/` |
+| `independent` | `illustrations/{topic-slug}/` |
+
+### 1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING
+
+**CRITICAL**: If EXTEND.md not found, MUST complete first-time setup before ANY other questions or steps. Do NOT proceed to reference images, do NOT ask about content, do NOT ask about type/style — ONLY complete the preferences setup first.
+
+```bash
+test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"
+test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"
+```
+
+| Result | Action |
+|--------|--------|
+| Found | Read, parse, display summary → Continue |
+| Not found | ⛔ **BLOCKING**: Run first-time setup ONLY ([config/first-time-setup.md](config/first-time-setup.md)) → Complete and save EXTEND.md → Then continue |
+
+**Supports**: Watermark | Preferred type/style | Custom styles | Language | Output directory
+
+---
+
+## Step 2: Setup & Analyze
+
+### 2.1 Analyze Content
+
+| Analysis | Description |
+|----------|-------------|
+| Content type | Technical / Tutorial / Methodology / Narrative |
+| Illustration purpose | information / visualization / imagination |
+| Core arguments | 2-5 main points to visualize |
+| Visual opportunities | Positions where illustrations add value |
+| Recommended type | Based on content signals and purpose |
+| Recommended density | Based on length and complexity |
+
+### 2.2 Extract Core Arguments
+
+- Main thesis
+- Key concepts reader needs
+- Comparisons/contrasts
+- Framework/model proposed
+
+**CRITICAL**: If article uses metaphors (e.g., "电锯切西瓜"), do NOT illustrate literally. Visualize the **underlying concept**.
+
+### 2.3 Identify Positions
+
+**Illustrate**:
+- Core arguments (REQUIRED)
+- Abstract concepts
+- Data comparisons
+- Processes, workflows
+
+**Do NOT Illustrate**:
+- Metaphors literally
+- Decorative scenes
+- Generic illustrations
+
+### 2.4 Analyze Reference Images (if provided in Step 1.0)
+
+For each reference image:
+
+| Analysis | Description |
+|----------|-------------|
+| Visual characteristics | Style, colors, composition |
+| Content/subject | What the reference depicts |
+| Suitable positions | Which sections match this reference |
+| Style match | Which illustration types/styles align |
+| Usage recommendation | `direct` / `style` / `palette` |
+
+| Usage | When to Use |
+|-------|-------------|
+| `direct` | Reference matches desired output closely |
+| `style` | Extract visual style characteristics only |
+| `palette` | Extract color scheme only |
+
+---
+
+## Step 3: Confirm Settings ⚠️
+
+**Do NOT skip.** Use ONE AskUserQuestion call with max 4 questions. **Q1, Q2, Q3 are ALL REQUIRED.**
+
+### Q1: Illustration Type ⚠️ REQUIRED
+- [Recommended based on analysis] (Recommended)
+- infographic / scene / flowchart / comparison / framework / timeline / mixed
+
+### Q2: Density ⚠️ REQUIRED - DO NOT SKIP
+- minimal (1-2) - Core concepts only
+- balanced (3-5) - Major sections
+- per-section - At least 1 per section/chapter (Recommended)
+- rich (6+) - Comprehensive coverage
+
+### Q3: Style ⚠️ REQUIRED (ALWAYS ask, even with preferred_style in EXTEND.md)
+
+If EXTEND.md has `preferred_style`:
+- [Custom style name + brief description] (Recommended)
+- [Top compatible core style 1]
+- [Top compatible core style 2]
+- Other (see full Style Gallery)
+
+If no `preferred_style` (present Core Styles first):
+- [Best compatible core style] (Recommended)
+- [Other compatible core style 1]
+- [Other compatible core style 2]
+- Other (see full Style Gallery)
+
+**Core Styles** (simplified selection):
+
+| Core Style | Best For |
+|------------|----------|
+| `minimal-flat` | General, knowledge sharing, SaaS |
+| `sci-fi` | AI, frontier tech, system design |
+| `hand-drawn` | Relaxed, reflective, casual |
+| `editorial` | Processes, data, journalism |
+| `scene` | Narratives, emotional, lifestyle |
+
+Style selection based on Type × Style compatibility matrix (styles.md).
+Full specs: `styles/<style>.md`
+
+### Q4: Image Text Language ⚠️ REQUIRED when article language ≠ EXTEND.md `language`
+
+Detect article language from content. If different from EXTEND.md `language` setting, MUST ask:
+- Article language (match article content) (Recommended)
+- EXTEND.md language (user's general preference)
+
+**Skip only if**: Article language matches EXTEND.md `language`, or EXTEND.md has no `language` setting.
+
+### Display Reference Usage (if references detected in Step 1.0)
+
+When presenting outline preview to user, show reference assignments:
+
+```
+Reference Images:
+| Ref | Filename | Recommended Usage |
+|-----|----------|-------------------|
+| 01 | 01-ref-diagram.png | direct → Illustration 1, 3 |
+| 02 | 02-ref-chart.png | palette → Illustration 2 |
+```
+
+---
+
+## Step 4: Generate Outline
+
+Save as `outline.md`:
+
+```yaml
+---
+type: infographic
+density: balanced
+style: blueprint
+image_count: 4
+references:                    # Only if references provided
+  - ref_id: 01
+    filename: 01-ref-diagram.png
+    description: "Technical diagram showing system architecture"
+  - ref_id: 02
+    filename: 02-ref-chart.png
+    description: "Color chart with brand palette"
+---
+
+## Illustration 1
+
+**Position**: [section] / [paragraph]
+**Purpose**: [why this helps]
+**Visual Content**: [what to show]
+**Type Application**: [how type applies]
+**References**: [01]                    # Optional: list ref_ids used
+**Reference Usage**: direct             # direct | style | palette
+**Filename**: 01-infographic-concept-name.png
+
+## Illustration 2
+...
+```
+
+**Requirements**:
+- Each position justified by content needs
+- Type applied consistently
+- Style reflected in descriptions
+- Count matches density
+- References assigned based on Step 2.4 analysis
+
+---
+
+## Step 5: Generate Images
+
+### 5.1 Create Prompts
+
+Follow [prompt-construction.md](prompt-construction.md). Save to `prompts/illustration-{slug}.md`.
+- **Backup rule**: If prompt file exists, rename to `prompts/illustration-{slug}-backup-YYYYMMDD-HHMMSS.md`
+
+**CRITICAL - References in Frontmatter**:
+- Only add `references` field if files ACTUALLY EXIST in `references/` directory
+- If style/palette was extracted verbally (no file), append info to prompt BODY instead
+- Before writing frontmatter, verify: `test -f references/NN-ref-{slug}.png`
+
+### 5.2 Select Generation Skill
+
+Check available skills. If multiple, ask user.
+
+### 5.3 Process References ⚠️ REQUIRED if references saved in Step 1.0
+
+**DO NOT SKIP if user provided reference images.** For each illustration with references:
+
+1. **VERIFY files exist first**:
+   ```bash
+   test -f references/NN-ref-{slug}.png && echo "exists" || echo "MISSING"
+   ```
+   - If file MISSING but in frontmatter → ERROR, fix frontmatter or remove references field
+   - If file exists → proceed with processing
+
+2. Read prompt frontmatter for reference info
+3. Process based on usage type:
+
+| Usage | Action | Example |
+|-------|--------|---------|
+| `direct` | Add reference path to `--ref` parameter | `--ref references/01-ref-brand.png` |
+| `style` | Analyze reference, append style traits to prompt | "Style: clean lines, gradient backgrounds..." |
+| `palette` | Extract colors from reference, append to prompt | "Colors: #E8756D coral, #7ECFC0 mint..." |
+
+4. Check image generation skill capability:
+
+| Skill Supports `--ref` | Action |
+|------------------------|--------|
+| Yes (e.g., baoyu-image-gen with Google) | Pass reference images via `--ref` |
+| No | Convert to text description, append to prompt |
+
+**Verification**: Before generating, confirm reference processing:
+```
+Reference Processing:
+- Illustration 1: using 01-ref-brand.png (direct) ✓
+- Illustration 2: extracted palette from 02-ref-style.png ✓
+```
+
+### 5.4 Apply Watermark (if enabled)
+
+Add: `Include a subtle watermark "[content]" at [position].`
+
+### 5.5 Generate
+
+1. For each illustration:
+   - **Backup rule**: If image file exists, rename to `NN-{type}-{slug}-backup-YYYYMMDD-HHMMSS.md`
+   - If references with `direct` usage: include `--ref` parameter
+   - Generate image
+2. After each: "Generated X/N"
+3. On failure: retry once, then log and continue
+
+---
+
+## Step 6: Finalize
+
+### 6.1 Update Article
+
+Insert after corresponding paragraph:
+```markdown
+![description](illustrations/{slug}/NN-{type}-{slug}.png)
+```
+
+Alt text: concise description in article's language.
+
+### 6.2 Output Summary
+
+```
+Article Illustration Complete!
+
+Article: [path]
+Type: [type] | Density: [level] | Style: [style]

-Use Bash to check EXTEND.md existence (priority order):
+### 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
-# Check project-level first
-test -f .baoyu-skills/baoyu-comic/EXTEND.md && echo "project"
-
-# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
-test -f "$HOME/.baoyu-skills/baoyu-comic/EXTEND.md" && echo "user"

-### Step 2: Confirmation 1 - Style & Options ⚠️
-
-**Purpose**: Select visual style + decide whether to review outline before generation. **Do NOT skip.**
-
-**Note**: Watermark and language already configured in EXTEND.md (Step 1).
-
-**Display summary**:
-- Content type + topic identified
-- Key figures extracted
-- Time span detected
-- Recommended page count
-- Language: [from EXTEND.md or detected]
-- **Recommended style**: [art] + [tone] (based on content signals)
-
-**Use AskUserQuestion** for:
-
-**Question 1: Visual Style**
-
-If a preset is recommended (see Auto Selection), show it first:
-
-```
-header: "Style"
-question: "Which visual style for this comic?"
-options:
-  - label: "[preset name] preset (Recommended)"       # If preset recommended
-    description: "[preset description] - includes special rules"
-  - label: "[recommended art] + [recommended tone] (Recommended)"  # If no preset
-    description: "Best match for your content based on analysis"
-  - label: "ligne-claire + neutral"
-    description: "Classic educational, Logicomix style"
-  - label: "ohmsha preset"
-    description: "Educational manga with visual metaphors, gadgets, NO talking heads"
-  - label: "Custom"
-    description: "Specify your own art + tone or preset"
-```
-
-**Preset vs Art+Tone**: Presets include special rules beyond art+tone. `ohmsha` = manga + neutral + visual metaphor rules + character roles + NO talking heads. Plain `manga + neutral` does NOT include these rules.
-
-**Question 2: Narrative Focus** (multiSelect: true)
-```
-header: "Focus"
-question: "What should the comic emphasize? (Select all that apply)"
-options:
-  - label: "Biography/life story"
-    description: "Follow a person's journey through key life events"
-  - label: "Concept explanation"
-    description: "Break down complex ideas visually"
-  - label: "Historical event"
-    description: "Dramatize important historical moments"
-  - label: "Tutorial/how-to"
-    description: "Step-by-step educational guide"
-```
-
-**Question 3: Target Audience**
-```
-header: "Audience"
-question: "Who is the primary reader?"
-options:
-  - label: "General readers"
-    description: "Broad appeal, accessible content"
-  - label: "Students/learners"
-    description: "Educational focus, clear explanations"
-  - label: "Industry professionals"
-    description: "Technical depth, domain knowledge"
-  - label: "Children/young readers"
-    description: "Simplified language, engaging visuals"
-```
-
-**Question 4: Outline Review**
-```
-header: "Review"
-question: "Do you want to review the outline before image generation?"
-options:
-  - label: "Yes, let me review (Recommended)"
-    description: "Review storyboard and characters before generating images"
-  - label: "No, generate directly"
-    description: "Skip outline review, start generating immediately"
-```
-
-**After response**:
-1. Update `analysis.md` with user preferences
-2. **Store `skip_outline_review`** flag based on Question 4 response
-3. → Step 3
-
-### Step 3: Generate Storyboard + Characters
-
-Create storyboard and character definitions using the confirmed style from Step 2.
-
-**Loading Style References**:
-- Art style: `references/art-styles/{art}.md`
-- Tone: `references/tones/{tone}.md`
-- If preset (ohmsha/wuxia/shoujo): also load `references/presets/{preset}.md`
-
-**Generate**:
-
-1. **Storyboard** (`storyboard.md`):
-   - YAML front matter with art_style, tone, layout, aspect_ratio
-   - Cover design
-   - Each page: layout, panel breakdown, visual prompts
-   - **Written in user's preferred language** (from Step 1)
-   - Reference: `references/storyboard-template.md`
-   - **If using preset**: Load and apply preset rules from `references/presets/`
-
-2. **Character definitions** (`characters/characters.md`):
-   - Visual specs matching the art style (in user's preferred language)
-   - Include Reference Sheet Prompt for later image generation
-   - Reference: `references/character-template.md`
-
-**After generation**:
-- If `skip_outline_review` is true → Skip Step 4, go directly to Step 5
-- If `skip_outline_review` is false → Continue to Step 4
-
-### Step 4: Confirmation 2 - Review Outline (Conditional)
-
-**Skip this step** if user selected "No, generate directly" in Step 2.
-
-**Purpose**: User reviews and confirms storyboard + characters before generation.
-
-**Display**:
-- Page count and structure
-- Art style + Tone combination
-- Page-by-page summary (Cover → P1 → P2...)
-- Character list with brief descriptions
-
-**Use AskUserQuestion**:
-
-```
-header: "Confirm"
-question: "Ready to generate images with this outline?"
-options:
-  - label: "Yes, proceed (Recommended)"
-    description: "Generate character sheet and comic pages"
-  - label: "Edit storyboard first"
-    description: "I'll modify storyboard.md before continuing"
-  - label: "Edit characters first"
-    description: "I'll modify characters/characters.md before continuing"
-  - label: "Edit both"
-    description: "I'll modify both files before continuing"
-```
-
-**After response**:
-1. If user wants to edit → Wait for user to finish editing, then ask again
-2. If user confirms → Continue to Step 5
-
-### Step 5: Generate Images
-
-With confirmed storyboard + art style + tone + aspect ratio:
-
-**Style Reference Loading**:
-- Read `references/art-styles/{art}.md` for rendering guidelines
-- Read `references/tones/{tone}.md` for mood/color adjustments
-- If preset: Read `references/presets/{preset}.md` for special rules
-
-**5.1 Generate Character Reference Sheet** (first):
-1. Use Reference Sheet Prompt from `characters/characters.md`
-2. Generate → `characters/characters.png`
-3. This ensures visual consistency for all subsequent pages
-
-**5.2 Generate Comic Pages**:
-
-**For each page (cover + pages)**:
-1. Save prompt to `prompts/NN-{cover|page}-[slug].md` (in user's preferred language)
-2. Generate image using confirmed art style and tone guidelines
-3. Report progress after each generation
-
-**Watermark Application** (if enabled in preferences):
-Add to each image generation prompt:
-```
-Include a subtle watermark "[content]" positioned at [position]
-with approximately [opacity*100]% visibility. The watermark should
-be legible but not distracting from the comic panels and storytelling.
-Ensure watermark does not overlap speech bubbles or key action.
-```
-Reference: `references/config/watermark-guide.md`
-
-**Image Generation Skill Selection**:
-- Check available image generation skills
-- If multiple skills available, ask user preference
-
-**Character Reference Handling** (IMPORTANT for visual consistency):
-
-1. Read the selected image generation skill's SKILL.md
-2. Check if it supports reference image input (look for parameters like `--ref`, `--reference`, `--image-ref`, etc.)
-
-| Skill Support | Action |
-|---------------|--------|
-| **Supports reference image** | Pass `characters/characters.png` using the skill's reference parameter |
-| **Does NOT support reference image** | Prepend `characters/characters.md` content to each page prompt |
-
-Always verify the exact parameter name from the skill's documentation before calling.
-
-**Session Management**:
-If image generation skill supports `--sessionId`:
-1. Generate unique session ID: `comic-{topic-slug}-{timestamp}`
-2. Use same session ID for all pages
-3. Ensures visual consistency across generated images
-
-### Step 6: Merge to PDF
-
-After all images generated:
-
-```bash
-npx -y bun ${SKILL_DIR}/scripts/merge-to-pdf.ts <comic-dir>
-```
-
-Creates `{topic-slug}.pdf` with all pages as full-page images.
-
-### Step 7: Completion Report
-
-```
-Comic Complete!
-Title: [title] | Art: [art] | Tone: [tone] | Pages: [count] | Aspect: [ratio] | Language: [lang]
-Watermark: [enabled/disabled]

+
+## 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-comic/EXTEND.md && echo "project"
+
+# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
+test -f "$HOME/.baoyu-skills/baoyu-comic/EXTEND.md" && echo "user"
+```
+
+| Path | Location |
+|------|----------|
+| `.baoyu-skills/baoyu-comic/EXTEND.md` | Project directory |
+| `$HOME/.baoyu-skills/baoyu-comic/EXTEND.md` | User home |
+
+**When EXTEND.md Found** → Read, parse, **output summary to user**:
+
+```
+📋 Loaded preferences from [full path]
+├─ Watermark: [enabled/disabled] [content if enabled]
+├─ Art Style: [style name or "auto-select"]
+├─ Tone: [tone name or "auto-select"]
+├─ Layout: [layout or "auto-select"]
+├─ Language: [language or "auto-detect"]
+└─ Character presets: [count] defined
+```
+
+**MUST output this summary** so user knows their current configuration. Do not skip or silently load.
+
+**When EXTEND.md Not Found** → First-time setup:
+
+1. Inform user: "No preferences found. Let's set up your defaults."
+2. Use AskUserQuestion to collect preferences (see `config/first-time-setup.md`)
+3. Create EXTEND.md at user-chosen location
+4. Confirm: "✓ Preferences saved to [path]"
+
+**EXTEND.md Supports**: Watermark | Preferred art/tone/layout | Custom style definitions | Character presets | Language preference
+
+Schema: `config/preferences-schema.md`
+
+**Important**: Once EXTEND.md exists, watermark, language, and style defaults are NOT asked again in Confirmation 1 or 2. These are session-persistent settings.
+
+### 1.2 Analyze Content → `analysis.md`
+
+Read source content, save it if needed, and perform deep analysis.
+
+**Actions**:
+1. **Save source content** (if not already a file):
+   - If user provides a file path: use as-is
+   - If user pastes content: save to `source.md` in target directory
+   - **Backup rule**: If `source.md` exists, rename to `source-backup-YYYYMMDD-HHMMSS.md`
+2. Read source content
+3. **Deep analysis** following `analysis-framework.md`:
+   - Target audience identification
+   - Value proposition for readers
+   - Core themes and narrative potential
+   - Key figures and their story arcs
+4. Detect source language
+5. **Determine language**:
+   - If EXTEND.md has `language` → use it
+   - Else if `--lang` option provided → use it
+   - Else → use detected source language
+6. Determine recommended page count:
+   - Short story: 5-8 pages
+   - Medium complexity: 9-15 pages
+   - Full biography: 16-25 pages
+7. Analyze content signals for art/tone/layout recommendations
+8. **Save to `analysis.md`**
+
+**analysis.md Format**: YAML front matter (title, topic, time_span, source_language, user_language, aspect_ratio, recommended_page_count, recommended_art, recommended_tone) + sections for Target Audience, Value Proposition, Core Themes, Key Figures & Story Arcs, Content Signals, Recommended Approaches. See `analysis-framework.md` for full template.
+
+### 1.3 Check Existing Content ⚠️ REQUIRED
+
+**MUST execute before proceeding to Step 2.**
+
+Use Bash to check if output directory exists:
+
+```bash
+test -d "comic/{topic-slug}" && echo "exists"
+```
+
+**If directory exists**, use AskUserQuestion:
+
+```
+header: "Existing"
+question: "Existing content found. How to proceed?"
+options:
+  - label: "Regenerate storyboard"
+    description: "Keep images, regenerate storyboard and characters only"
+  - label: "Regenerate images"
+    description: "Keep storyboard, 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 result and handle accordingly:
+- **Regenerate storyboard**: Skip to Step 3, preserve `prompts/` and images
+- **Regenerate images**: Skip to Step 7, use existing prompts
+- **Backup and regenerate**: Move directory, start fresh from Step 2
+- **Exit**: End workflow immediately
+
+---
+
+## Step 2: Confirmation 1 - Style & Options ⚠️
+
+**Purpose**: Select visual style + decide whether to review outline before generation. **Do NOT skip.**
+
+**Note**: Watermark and language already configured in EXTEND.md (Step 1).
+
+**Display summary**:
+- Content type + topic identified
+- Key figures extracted
+- Time span detected
+- Recommended page count
+- Language: [from EXTEND.md or detected]
+- **Recommended style**: [art] + [tone] (based on content signals)
+
+**Use AskUserQuestion** for:
+
+### Question 1: Visual Style
+
+If a preset is recommended (see `auto-selection.md`), show it first:
+
+```
+header: "Style"
+question: "Which visual style for this comic?"
+options:
+  - label: "[preset name] preset (Recommended)"       # If preset recommended
+    description: "[preset description] - includes special rules"
+  - label: "[recommended art] + [recommended tone] (Recommended)"  # If no preset
+    description: "Best match for your content based on analysis"
+  - label: "ligne-claire + neutral"
+    description: "Classic educational, Logicomix style"
+  - label: "ohmsha preset"
+    description: "Educational manga with visual metaphors, gadgets, NO talking heads"
+  - label: "Custom"
+    description: "Specify your own art + tone or preset"
+```
+
+**Preset vs Art+Tone**: Presets include special rules beyond art+tone. `ohmsha` = manga + neutral + visual metaphor rules + character roles + NO talking heads. Plain `manga + neutral` does NOT include these rules.
+
+### Question 2: Narrative Focus (multiSelect: true)
+
+```
+header: "Focus"
+question: "What should the comic emphasize? (Select all that apply)"
+options:
+  - label: "Biography/life story"
+    description: "Follow a person's journey through key life events"
+  - label: "Concept explanation"
+    description: "Break down complex ideas visually"
+  - label: "Historical event"
+    description: "Dramatize important historical moments"
+  - label: "Tutorial/how-to"
+    description: "Step-by-step educational guide"
+```
+
+### Question 3: Target Audience
+
+```
+header: "Audience"
+question: "Who is the primary reader?"
+options:
+  - label: "General readers"
+    description: "Broad appeal, accessible content"
+  - label: "Students/learners"
+    description: "Educational focus, clear explanations"
+  - label: "Industry professionals"
+    description: "Technical depth, domain knowledge"
+  - label: "Children/young readers"
+    description: "Simplified language, engaging visuals"
+```
+
+### Question 4: Outline Review
+
+```
+header: "Review"
+question: "Do you want to review the outline before image generation?"
+options:
+  - label: "Yes, let me review (Recommended)"
+    description: "Review storyboard and characters before generating images"
+  - label: "No, generate directly"
+    description: "Skip outline review, start generating immediately"
+```
+
+### Question 5: Prompt Review
+
+```
+header: "Prompts"
+question: "Review prompts before generating images?"
+options:
+  - label: "Yes, review prompts (Recommended)"
+    description: "Review image generation prompts before generating"
+  - label: "No, skip prompt review"
+    description: "Proceed directly to image generation"
+```
+
+**After response**:
+1. Update `analysis.md` with user preferences
+2. **Store `skip_outline_review`** flag based on Question 4 response
+3. **Store `skip_prompt_review`** flag based on Question 5 response
+4. → Step 3
+
+---
+
+## Step 3: Generate Storyboard + Characters
+
+Create storyboard and character definitions using the confirmed style from Step 2.
+
+**Loading Style References**:
+- Art style: `art-styles/{art}.md`
+- Tone: `tones/{tone}.md`
+- If preset (ohmsha/wuxia/shoujo): also load `presets/{preset}.md`
+
+**Generate**:
+
+1. **Storyboard** (`storyboard.md`):
+   - YAML front matter with art_style, tone, layout, aspect_ratio
+   - Cover design
+   - Each page: layout, panel breakdown, visual prompts
+   - **Written in user's preferred language** (from Step 1)
+   - Reference: `storyboard-template.md`
+   - **If using preset**: Load and apply preset rules from `presets/`
+
+2. **Character definitions** (`characters/characters.md`):
+   - Visual specs matching the art style (in user's preferred language)
+   - Include Reference Sheet Prompt for later image generation
+   - Reference: `character-template.md`
+   - **If using ohmsha preset**: Use default Doraemon characters (see below)
+
+**Ohmsha Default Characters** (use these unless user specifies `--characters`):
+
+| Role | Character | Visual Description |
+|------|-----------|-------------------|
+| Student | 大雄 (Nobita) | Japanese boy, 10yo, round glasses, black hair parted in middle, yellow shirt, navy shorts |
+| Mentor | 哆啦A梦 (Doraemon) | Round blue robot cat, big white eyes, red nose, whiskers, white belly with 4D pocket, golden bell, no ears |
+| Challenge | 胖虎 (Gian) | Stocky boy, rough features, small eyes, orange shirt |
+| Support | 静香 (Shizuka) | Cute girl, black short hair, pink dress, gentle expression |
+
+These are the canonical ohmsha-style characters. Do NOT create custom characters for ohmsha unless explicitly requested.
+
+**After generation**:
+- If `skip_outline_review` is true → Skip Step 4, go directly 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, generate directly" in Step 2.
+
+**Purpose**: User reviews and confirms storyboard + characters before generation.
+
+**Display**:
+- Page count and structure
+- Art style + Tone combination
+- Page-by-page summary (Cover → P1 → P2...)
+- Character list with brief descriptions
+
+**Use AskUserQuestion**:
+
+```
+header: "Confirm"
+question: "Ready to generate images with this outline?"
+options:
+  - label: "Yes, proceed (Recommended)"
+    description: "Generate character sheet and comic pages"
+  - label: "Edit storyboard first"
+    description: "I'll modify storyboard.md before continuing"
+  - label: "Edit characters first"
+    description: "I'll modify characters/characters.md before continuing"
+  - label: "Edit both"
+    description: "I'll modify both files before continuing"
+```
+
+**After response**:
+1. If user wants to edit → Wait for user to finish editing, then ask again
+2. If user confirms → Continue to Step 5
+
+---
+
+## Step 5: Generate Prompts
+
+Create image generation prompts for all pages.
+
+**Style Reference Loading**:
+- Read `art-styles/{art}.md` for rendering guidelines
+- Read `tones/{tone}.md` for mood/color adjustments
+- If preset: Read `presets/{preset}.md` for special rules
+
+**For each page (cover + pages)**:
+1. Create prompt following art style + tone guidelines
+2. Include character visual descriptions for consistency
+3. Save to `prompts/NN-{cover|page}-[slug].md`
+   - **Backup rule**: If prompt file exists, rename to `prompts/NN-{cover|page}-[slug]-backup-YYYYMMDD-HHMMSS.md`
+
+**Prompt File Format**:
+```markdown
+# Page NN: [Title]
+
+## Visual Style
+Art: [art style] | Tone: [tone] | Layout: [layout type]
+
+## Character Reference
+[Character descriptions from characters/characters.md]
+
+## Panel Breakdown
+[From storyboard.md - panel descriptions, actions, dialogue]
+
+## Generation Prompt
+[Combined prompt for image generation skill]
+```
+
+**Watermark Application** (if enabled in preferences):
+Add to each prompt:
+```
+Include a subtle watermark "[content]" positioned at [position]
+with approximately [opacity*100]% visibility. The watermark should
+be legible but not distracting from the comic panels and storytelling.
+Ensure watermark does not overlap speech bubbles or key action.
+```
+Reference: `config/watermark-guide.md`
+
+**After generation**:
+- If `skip_prompt_review` is true → Skip Step 6, go directly 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**: User reviews and confirms prompts before image generation.
+
+**Display prompt summary table**:
+
+| Page | Title | Key Elements |
+|------|-------|--------------|
+| Cover | [title] | [main visual] |
+| P1 | [title] | [key elements] |
+| ... | ... | ... |
+
+**Use AskUserQuestion**:
+
+```
+header: "Confirm"
+question: "Ready to generate images with these prompts?"
+options:
+  - label: "Yes, proceed (Recommended)"
+    description: "Generate all comic page images"
+  - label: "Edit prompts first"
+    description: "I'll modify prompts/*.md before continuing"
+  - label: "Regenerate prompts"
+    description: "Regenerate all prompts with different approach"
+```
+
+**After response**:
+1. If user wants to edit → Wait for user to finish editing, then ask again
+2. If user wants to regenerate → Go back to Step 5
+3. If user confirms → Continue to Step 7
+
+---
+
+## Step 7: Generate Images
+
+With confirmed prompts from Step 5/6:
+
+### 7.1 Generate Character Reference Sheet (first)
+
+1. Use Reference Sheet Prompt from `characters/characters.md`
+2. **Backup rule**: If `characters/characters.png` exists, rename to `characters/characters-backup-YYYYMMDD-HHMMSS.png`
+3. Generate → `characters/characters.png`
+4. This ensures visual consistency for all subsequent pages
+
+### 7.2 Generate Comic Pages
+
+**CRITICAL: Character Reference is MANDATORY** for visual consistency across all pages.
+
+**Before generating any page**:
+1. Read the image generation skill's SKILL.md
+2. Check if it supports reference image input (`--ref`, `--reference`, etc.)
+3. Choose the appropriate strategy below
+
+**Character Reference Strategy**:
+
+| Skill Capability | Strategy | Action |
+|------------------|----------|--------|
+| Supports `--ref` | **Strategy A** | Pass `characters/characters.png` with EVERY page |
+| Does NOT support `--ref` | **Strategy B** | Prepend character descriptions to EVERY prompt |
+
+**Strategy A: Using `--ref` parameter** (e.g., baoyu-image-gen)
+
+```bash
+# Each page generation MUST include --ref
+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
+```
+
+**Strategy B: Embedding character descriptions in prompt**
+
+When skill does NOT support reference images, create combined prompt files:
+
+```markdown
+# prompts/01-page-xxx.md (with embedded character reference)
+
+## Character Reference (maintain consistency)
+[Copy relevant sections from characters/characters.md here]
+- 大雄: Japanese boy, round glasses, yellow shirt, navy shorts...
+- 哆啦A梦: Round blue robot cat, white belly, red nose, golden bell...
+
+## Page Content
+[Original page prompt here]
+```
+
+**For each page (cover + pages)**:
+1. Read prompt from `prompts/NN-{cover|page}-[slug].md`
+2. **Backup rule**: If image file exists, rename to `NN-{cover|page}-[slug]-backup-YYYYMMDD-HHMMSS.png`
+3. Generate image using Strategy A or B (based on skill capability)
+4. Save to `NN-{cover|page}-[slug].png`
+5. Report progress after each generation: "Generated X/N: [page title]"
+
+**Session Management**:
+If image generation skill supports `--sessionId`:
+1. Generate unique session ID: `comic-{topic-slug}-{timestamp}`
+2. Use same session ID for all pages
+3. Ensures visual consistency across generated images
+
+---
+
+## Step 8: Merge to PDF
+
+After all images generated:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/merge-to-pdf.ts <comic-dir>
+```
+
+Creates `{topic-slug}.pdf` with all pages as full-page images.
+
+---
+
+## Step 9: Completion Report
+
+```
+Comic Complete!
+Title: [title] | Art: [art] | Tone: [tone] | Pages: [count] | Aspect: [ratio] | Language: [lang]
+Watermark: [enabled/disabled]
+Location: [path]
+✓ analysis.md
+✓ characters.png
+✓ 00-cover-[slug].png ... NN-page-[slug].png
+✓ {topic-slug}.pdf
+```
+
+---
+
+## Page Modification
+
+| Action | Steps |
+|--------|-------|
+| **Edit** | Update prompt → Regenerate image → Regenerate PDF |
+| **Add** | Create prompt at position → Generate image → Renumber subsequent (NN+1) → Update storyboard → Regenerate PDF |
+| **Delete** | Remove files → Renumber subsequent (NN-1) → Update storyboard → Regenerate PDF |
+
+**File naming**: `NN-{cover|page}-[slug].png` (e.g., `03-page-enigma-machine.png`)
+- Slugs: kebab-case, unique, derived from content
+- Renumbering: Update NN prefix only, slugs unchanged

-- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
-- Example: `ai-future` exists → `ai-future-20260118-143052`
-
-### Source Files
-
-Copy all sources with naming `source-{slug}.{ext}`:
-- `source-article.md` (main text content)
-- `source-logo.png` (image from conversation)
-
-Multiple sources supported: text, images, files from conversation.
+**Slug**: 2-4 words, kebab-case. Conflict: append `-YYYYMMDD-HHMMSS`
 
 ## Workflow
 
+### Progress Checklist
+
+```
+Cover Image Progress:
+- [ ] Step 0: Check preferences (EXTEND.md) ⛔ BLOCKING
+- [ ] Step 1: Analyze content + save refs + determine output dir
+- [ ] Step 2: Confirm options (6 dimensions) ⚠️ unless --quick
+- [ ] Step 3: Create prompt
+- [ ] Step 4: Generate image
+- [ ] Step 5: Completion report
+```
+
+### Flow
+
+```
+Input → [Step 0: Preferences] ─┬─ Found → Continue
+                               └─ Not found → First-Time Setup ⛔ BLOCKING → Save EXTEND.md → Continue
+        ↓
+Analyze + Save Refs → [Output Dir] → [Confirm: 6 Dimensions] → Prompt → Generate → Complete
+                                              ↓
+                                     (skip if --quick or all specified)
+```
+
+### Step 0: Load Preferences ⛔ BLOCKING
+
+Check EXTEND.md existence (priority: project → user):
+```bash
+test -f .baoyu-skills/baoyu-cover-image/EXTEND.md && echo "project"
+test -f "$HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md" && echo "user"
+```
+
+| Result | Action |
+|--------|--------|
+| Found | Load, display summary → Continue |
+| Not found | ⛔ Run first-time setup ([references/config/first-time-setup.md](references/config/first-time-setup.md)) → Save → Continue |
+
+**CRITICAL**: If not found, complete setup BEFORE any other steps or questions.
+
 ### Step 1: Analyze Content
 
-1. **Save source content** (if not already a file):
-   - If user provides a file path: use as-is
-   - If user pastes content: save to `source.md` in target directory
+1. **Save reference images** (if provided) → [references/workflow/reference-images.md](references/workflow/reference-images.md)
+2. **Save source content** (if pasted, save to `source.md`)
+3. **Analyze content**: topic, tone, keywords, visual metaphors
+4. **Deep analyze references** ⚠️: Extract specific, concrete elements (see reference-images.md)
+5. **Detect language**: Compare source, user input, EXTEND.md preference
+6. **Determine output directory**: Per File Structure rules
 
-2. **Extract key information**:
-   - **Main topic**: What is the article about?
-   - **Core message**: What's the key takeaway?
-   - **Tone**: Serious, playful, inspiring, educational?
-   - **Keywords**: Identify style-signaling words
+### Step 2: Confirm Options ⚠️
 
-3. **Language detection**:
-   - Detect **source language** from content
-   - Detect **user language** from conversation context
-   - Note if source_language ≠ user_language (will ask in Step 3)
+Full confirmation flow: [references/workflow/confirm-options.md](references/workflow/confirm-options.md)
 
-### Step 2: Determine Options
+| Condition | Skipped | Still Asked |
+|-----------|---------|-------------|
+| `--quick` or `quick_mode: true` | 6 dimensions | Aspect ratio (unless `--aspect`) |
+| All 6 + `--aspect` specified | All | None |
 
-1. **Style selection**:
-   - If `--style` specified, use that style
-   - Otherwise, scan content for style signals and auto-select 3 candidates
-   - Default to `elegant` if no clear signals
+### Step 3: Create Prompt
 
-2. **Aspect ratio**:
-   - If `--aspect` specified, use that ratio
-   - Otherwise, prepare options: 2.35:1 (cinematic), 16:9 (widescreen), 1:1 (social)
+Save to `prompts/cover.md`. Template: [references/workflow/prompt-template.md](references/workflow/prompt-template.md)
 
-### Step 3: Confirm Options
+**CRITICAL - References in Frontmatter**:
+- Files saved to `refs/` → Add to frontmatter `references` list
+- Style extracted verbally (no file) → Omit `references`, describe in body
+- Before writing → Verify: `test -f refs/ref-NN-{slug}.{ext}`
 
-**Purpose**: Let user confirm all options in a single step before generation.
+**Reference elements in body** MUST be detailed, prefixed with "MUST"/"REQUIRED", with integration approach.
 
-**IMPORTANT**: Present ALL options in a single confirmation step using AskUserQuestion. Do NOT interrupt workflow with multiple separate confirmations.
+### Step 4: Generate Image
 
-**Determine which questions to ask**:
+1. **Backup existing** `cover.png` if regenerating
+2. **Check image generation skills**; if multiple, ask preference
+3. **Process references** from prompt frontmatter:
+   - `direct` usage → pass via `--ref` (use ref-capable backend)
+   - `style`/`palette` → extract traits, append to prompt
+4. **Generate**: Call skill with prompt file, output path, aspect ratio
+5. On failure: auto-retry once
 
-| Question | When to Ask |
-|----------|-------------|
-| Style | Always (required) |
-| Aspect ratio | Always (offer common options) |
-| Language | Only if `source_language ≠ user_language` |
-
-**Present options** (use AskUserQuestion with all applicable questions):
-
-**Question 1 (Style)** - always:
-- Style A (recommended): [style name] - [brief description]
-- Style B: [style name] - [brief description]
-- Style C: [style name] - [brief description]
-- Custom: Provide custom style reference
-
-**Question 2 (Aspect)** - always:
-- 2.35:1 Cinematic (Recommended) - ultra-wide, dramatic
-- 16:9 Widescreen - standard video/presentation
-- 1:1 Square - social media optimized
-
-**Question 3 (Language)** - only if source ≠ user language:
-- [Source language] (matches content)
-- [User language] (your preference)
-
-**Language handling**:
-- If source language = user language: Just inform user (e.g., "Title will be in Chinese")
-- If different: Ask which language to use for title text
-
-### Step 4: Generate Cover Concept
-
-Create a cover image concept based on selected style:
-
-**Title** (if included, max 8 characters):
-- Distill the core message into a punchy headline
-- Use hooks: numbers, questions, contrasts, pain points
-- Skip if `--no-title` flag is used
-
-**Visual Elements**:
-- Style-appropriate imagery and icons
-- 1-2 symbolic elements representing the topic
-- Metaphors or analogies that fit the style
-
-### Step 5: Create Prompt File
-
-Save prompt to `prompts/cover.md` with confirmed options.
-
-**All prompts are written in the user's confirmed language preference.**
-
-**Prompt Format**:
-
-```markdown
-Cover theme: [topic in 2-3 words]
-Style: [selected style name]
-Aspect ratio: [confirmed aspect ratio]
-
-[If title included:]
-Title text: [8 characters or less, in confirmed language]
-Subtitle: [optional, in confirmed language]
-
-Visual composition:
-- Main visual: [description matching style]
-- Layout: [positioning based on title inclusion and aspect ratio]
-- Decorative elements: [style-appropriate elements]
-
-Color scheme:
-- Primary: [style primary color]
-- Background: [style background color]
-- Accent: [style accent color]
-
-Style notes: [specific style characteristics to emphasize]
-
-[If no title:]
-Note: No title text, pure visual illustration only.
-```
-
-### Step 6: Generate Image
-
-**Image Generation Skill Selection**:
-1. Check available image generation skills
-2. If multiple skills available, ask user to choose
-
-**Generation**:
-Call selected image generation skill with prompt file, output path, and confirmed aspect ratio.
-
-### Step 7: Output Summary
+### Step 5: Completion Report
 
 ```
-Cover Image Generated!
+Cover Generated!
 
 Topic: [topic]
-Style: [style name]
-Aspect: [aspect ratio]
-Title: [cover title] (or "No title - visual only")
-Language: [confirmed language]
-Location: [output path]
+Type: [type] | Palette: [palette] | Rendering: [rendering]
+Text: [text] | Mood: [mood] | Font: [font] | Aspect: [ratio]
+Title: [title or "visual only"]
+Language: [lang] | Watermark: [enabled/disabled]
+References: [N images or "extracted style" or "none"]
+Location: [directory path]
 
-Preview the image to verify it matches your expectations.
+Files:
+✓ source-{slug}.{ext}
+✓ prompts/cover.md
+✓ cover.png
 ```
 
-## Notes
+## Image Modification
 
-- Cover should be instantly understandable at small preview sizes
-- Title (if included) must be readable and impactful
-- Visual metaphors work better than literal representations
-- Maintain style consistency throughout the cover
-- Image generation typically takes 10-30 seconds
-- Title text uses user's confirmed language preference
-- Aspect ratio: 2.35:1 for cinematic/dramatic, 16:9 for widescreen, 1:1 for social media
+| Action | Steps |
+|--------|-------|
+| **Regenerate** | Backup → Update prompt file FIRST → Regenerate |
+| **Change dimension** | Backup → Confirm new value → Update prompt → Regenerate |
+
+## Composition Principles
+
+- **Whitespace**: 40-60% breathing room
+- **Visual anchor**: Main element centered or offset left
+- **Characters**: Simplified silhouettes; NO realistic humans
+- **Title**: Use exact title from user/source; never invent

+Create a cover image following these guidelines:
 
 ## Image Specifications
 
 - **Type**: Cover image / Hero image
-- **Aspect Ratio**: 2.35:1 (WeChat article cover standard)
-- **Style**: Hand-drawn illustration
+- **Aspect Ratio**: As specified in the prompt below
 
 ## Core Principles
 
-- Hand-drawn quality throughout - NO realistic or photographic elements
 - If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
 - Ample whitespace, highlight core message, avoid cluttered layouts
 - Main visual elements centered or slightly left (leave right side for title area if title included)
+- Simplified silhouettes for any characters — NO realistic human faces or bodies
+- Icon-based vocabulary: use simple, recognizable icons to represent concepts
+
+## Five Dimensions
+
+### Type (Visual Composition)
+- `hero`: Large focal visual (60-70% area), dramatic composition
+- `conceptual`: Abstract shapes, information hierarchy, clean zones
+- `typography`: Title as primary element (40%+ area), minimal visuals
+- `metaphor`: Concrete object representing abstract idea, symbolic elements
+- `scene`: Atmospheric environment, narrative elements, mood lighting
+- `minimal`: Single focal element, generous whitespace (60%+)
+
+### Palette (Color Scheme)
+Apply the specified palette's color values and decorative hints:
+- Use primary colors for main visual elements
+- Use background colors for base and surrounding areas
+- Use accent colors for highlights and secondary elements
+- Follow palette-specific decorative hints for ornamentation
+
+### Rendering (Visual Style)
+Apply the specified rendering's characteristics:
+- **Lines**: Follow line quality rules (clean/sketchy/brush/pixel/chalk)
+- **Texture**: Apply or avoid texture per rendering definition
+- **Depth**: Follow depth rules (flat/minimal/soft edges)
+- **Elements**: Use rendering-specific element vocabulary
+
+### Text (Density Level)
+- `none`: No text elements, full visual area
+- `title-only`: Single headline, 85% visual area
+- `title-subtitle`: Title + context, 75% visual area
+- `text-rich`: Title + subtitle + 2-4 keyword tags, 60% visual area
+
+### Mood (Emotional Intensity)
+- `subtle`: Low contrast, muted/desaturated colors, light visual weight, calm aesthetic
+- `balanced`: Medium contrast, normal saturation, balanced visual weight
+- `bold`: High contrast, vivid/saturated colors, heavy visual weight, dynamic energy
 
 ## Text Style (When Title Included)
 
-- **ALL text MUST be hand-drawn style**
-- Title text: Large, eye-catching, max 8 characters
-- May include 1 line of subtitle or keyword tags
-- Font style harmonizes with illustration style
-- **DO NOT use realistic or computer-generated fonts**
+- **Title source**: Use the exact title provided by user, or extract from source content. Do NOT invent or modify titles.
+- Title text: Large, eye-catching, faithful to source
+- Subtitle: Secondary element (if title-subtitle or text-rich)
+- Tags: 2-4 keyword badges (if text-rich)
+- Font style harmonizes with rendering style
+
+## Composition Guidance
+
+### Layout Principles
+
+- **Generous whitespace**: Maintain 40-60% breathing room; avoid cluttered compositions
+- **Visual anchor placement**: Main element centered or offset left (reserve right side for title if included)
+- **Information hierarchy**: One dominant focal point, 1-2 supporting elements, decorative accents
+- **Clean backgrounds**: Solid colors or subtle gradients; no complex textures or patterns
+
+### Icon & Symbol Vocabulary
+
+Represent concepts with simple, recognizable icons rather than detailed illustrations:
+
+| Category | Examples |
+|----------|----------|
+| Tech | Code window, gear, circuit, cloud, lock, API brackets |
+| Ideas | Lightbulb, rocket, target, puzzle, key, magnifier |
+| Communication | Speech bubble, chat dots, megaphone, mail |
+| Growth | Plant/sprout, tree, arrow, chart, mountain |
+| Tools | Wrench, pencil, brush, checklist, clock |
+
+Use the rendering style to determine icon complexity (flat-vector = geometric, hand-drawn = sketchy, etc.)
+
+Full library: [references/visual-elements.md](visual-elements.md)
+
+### Character Handling
+
+When people are needed:
+- Use simplified silhouettes or abstract stick figures
+- Symbolic representations (head + shoulders outline)
+- NO realistic faces, detailed anatomy, or photographic representations
+- Cartoon/icon style consistent with rendering choice
+
+## Mood Application
+
+Apply mood adjustments to the base palette:
+
+| Mood | Contrast | Saturation | Weight |
+|------|----------|------------|--------|
+| subtle | Reduce 20-30% | Desaturate 20-30% | Lighter strokes/fills |
+| balanced | Standard | Standard | Standard |
+| bold | Increase 20-30% | Increase 20-30% | Heavier strokes/fills |
 
 ## Language
 
 - Use the same language as the content provided below for any text elements
 - Match punctuation style to the content language
 
+## Reference Images
+
+When reference images are provided:
+
+- **Style extraction**: Identify rendering technique, line quality, texture, and visual vocabulary
+- **Composition learning**: Note layout patterns, whitespace usage, element placement
+- **Mood matching**: Capture the emotional tone and visual weight
+- **Adaptation**: Apply extracted characteristics while respecting the specified Type, Palette, and Rendering dimensions
+- **Priority**: If reference style conflicts with specified dimensions, dimensions take precedence for structural choices; reference influences decorative details

+
+## Position Recommendations
+
+| Position | Best For | Avoid When |
+|----------|----------|------------|
+| `bottom-right` | Default choice, most common | Title in bottom-right |
+| `bottom-left` | Right-heavy layouts | Key visual in bottom-left |
+| `bottom-center` | Centered designs | Text-heavy bottom area |
+| `top-right` | Bottom-heavy content | Title/header in top-right |
+
+## Content Format
+
+| Format | Example | Style |
+|--------|---------|-------|
+| Handle | `@username` | Social media |
+| Domain | `myblog.com` | Cross-platform |
+| Brand | `MyBrand` | Simple branding |
+| Chinese | `博客名` | Chinese platforms |
+
+## Best Practices
+
+1. **Consistency**: Use same watermark across all covers
+2. **Legibility**: Ensure watermark readable on both light/dark areas
+3. **Size**: Keep subtle - should not distract from content
+
+## Prompt Integration
+
+When watermark is enabled, add to image generation prompt:
+
+```
+Include a subtle watermark "[content]" positioned at [position].
+The watermark should be legible but not distracting from the main content.
+```
+
+## Cover-Specific Considerations
+
+| Aspect Ratio | Recommended Position | Notes |
+|--------------|---------------------|-------|
+| 2.35:1 | bottom-right | Cinematic - keep corners clean |
+| 16:9 | bottom-right | Standard - flexible placement |
+| 1:1 | bottom-center | Square - centered often works better |
+
+## Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| Watermark invisible | Adjust position or check contrast |
+| Watermark too prominent | Change position or reduce size |
+| Watermark overlaps title | Change position or reduce title area |

+
+## Reference-Driven Design ⚠️ HIGH PRIORITY
+
+When reference images are provided, they are the **primary visual input** and MUST strongly influence the output. The cover should look like it belongs to the same visual family as the references.
+
+**Passing `--ref` alone is NOT enough.** Image generation models often ignore reference images unless the prompt text explicitly describes what to reproduce. Always combine `--ref` with detailed textual instructions.
+
+## Content-Driven Design
+
+- Article title and summary inform the visual metaphor choice
+- Keywords guide decorative elements and symbols
+- The skill controls visual style; the content drives meaning
+
+## Visual Element Selection
+
+Match content themes to icon vocabulary:
+
+| Content Theme | Suggested Elements |
+|---------------|-------------------|
+| Programming/Dev | Code window, terminal, API brackets, gear |
+| AI/ML | Brain, neural network, robot, circuit |
+| Growth/Business | Chart, rocket, plant, mountain, arrow |
+| Security | Lock, shield, key, fingerprint |
+| Communication | Speech bubble, megaphone, mail, handshake |
+| Tools/Methods | Wrench, checklist, pencil, puzzle |
+
+Full library: [../visual-elements.md](../visual-elements.md)
+
+## Type-Specific Composition
+
+| Type | Composition Guidelines |
+|------|------------------------|
+| `hero` | Large focal visual (60-70% area), title overlay on visual, dramatic composition |
+| `conceptual` | Abstract shapes representing core concepts, information hierarchy, clean zones |
+| `typography` | Title as primary element (40%+ area), minimal supporting visuals, strong hierarchy |
+| `metaphor` | Concrete object/scene representing abstract idea, symbolic elements, emotional resonance |
+| `scene` | Atmospheric environment, narrative elements, mood-setting lighting and colors |
+| `minimal` | Single focal element, generous whitespace (60%+), essential shapes only |
+
+## Title Guidelines
+
+When text level includes title:
+- **Source**: Use the exact title provided by user, or extract from source content
+- **Do NOT invent titles**: Stay faithful to the original
+- Match confirmed language
+
+## Watermark Application
+
+If enabled in preferences, add to prompt:
+
+```
+Include a subtle watermark "[content]" positioned at [position].
+The watermark should be legible but not distracting from the main content.
+```
+
+Reference: `config/watermark-guide.md`
+
+## Reference Image Handling
+
+When user provides reference images (`--ref` or pasted images):
+
+### ⚠️ CRITICAL - Frontmatter References
+
+**MUST add `references` field in YAML frontmatter** when reference files are saved to `refs/`:
+
+```yaml
+---
+type: cover
+palette: warm
+rendering: flat-vector
+references:
+  - ref_id: 01
+    filename: refs/ref-01-podcast-thumbnail.jpg
+    usage: style
+---
+```
+
+| Field | Description |
+|-------|-------------|
+| `ref_id` | Sequential number (01, 02, ...) |
+| `filename` | Relative path from prompt file's parent directory |
+| `usage` | `direct` / `style` / `palette` |
+
+**Omit `references` field entirely** if no reference files saved (style extracted verbally only).
+
+### When to Include References in Frontmatter
+
+| Situation | Frontmatter Action | Generation Action |
+|-----------|-------------------|-------------------|
+| Reference file saved to `refs/` | Add to `references` list ✓ | Pass via `--ref` parameter |
+| Style extracted verbally (no file) | Omit `references` field | Describe in prompt body only |
+| File path in frontmatter but doesn't exist | ERROR - fix or remove | Generation will fail |
+
+**Before writing prompt with references, verify**: `test -f refs/ref-NN-{slug}.{ext}`
+
+### Reference Usage Types
+
+| Usage | When to Use | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Reference matches desired output closely | Pass to `--ref` parameter |
+| `style` | Extract visual style characteristics only | Describe style in prompt text |
+| `palette` | Extract color palette only | Include colors in prompt |
+
+### Step 1: Analyze References
+
+For each reference image, extract:
+- **Style**: Rendering technique, line quality, texture
+- **Composition**: Layout, visual hierarchy, focal points
+- **Color mood**: Palette characteristics (without specific colors)
+- **Elements**: Key visual elements and symbols used
+
+### Step 2: Embed in Prompt ⚠️ CRITICAL
+
+**Passing `--ref` alone is NOT enough.** Image generation models frequently ignore reference images unless the prompt text explicitly and forcefully describes what to reproduce. You MUST always write detailed textual instructions regardless of whether `--ref` is used.
+
+**If file saved (with or without `--ref` support)**:
+- Pass ref images via `--ref` parameter if skill supports it
+- **ALWAYS** add a detailed mandatory section in the prompt body:
+
+```
+# Reference Style — MUST INCORPORATE
+
+CRITICAL: The generated cover MUST visually reference the provided images. The cover must feel like it belongs to the same visual family.
+
+## From Ref 1 ([filename]) — REQUIRED elements:
+- [Brand element]: [Specific description of logo/wordmark treatment, e.g., "The logo uses vertical parallel lines (|||) for the letter 'm'. Reproduce this exact treatment."]
+- [Signature pattern]: [Specific description, e.g., "Woven intersecting curves forming a diamond/lozenge grid pattern. This MUST appear prominently as a banner, border, or background section."]
+- [Colors]: [Exact hex values, e.g., "Dark teal #2D4A3E background, cream #F5F0E0 text"]
+- [Typography]: [Specific treatment, e.g., "Uppercase text with wide letter-spacing"]
+- [Layout element]: [Specific spatial element, e.g., "Bottom banner strip in dark color"]
+
+## From Ref 2 ([filename]) — REQUIRED elements:
+[Same detailed breakdown]
+
+## Integration approach:
+[Specific layout instruction describing how reference elements combine with the cover content, e.g., "Use a SPLIT LAYOUT: main illustration area (warm cream background) occupies ~65% of the image, while a dark teal BANNER STRIP (with the woven line pattern from Ref 2) runs along the bottom ~35%, containing branding elements from Ref 1."]
+```
+
+**Key rules**:
+- Each visual element gets its own bullet with "MUST" or "REQUIRED"
+- Descriptions must be **specific enough to reproduce** — not vague ("clean style")
+- The integration approach must describe **exact spatial arrangement**
+- After generation, verify reference elements are visible; if not, strengthen and regenerate
+
+**If style/palette extracted verbally (NO file saved)**:
+- DO NOT add references metadata to prompt
+- Append extracted info directly to prompt body using the same MUST INCORPORATE format above:
+
+```
+# Reference Style — MUST INCORPORATE (extracted from visual analysis)
+
+CRITICAL: Apply these specific visual elements extracted from the reference images.
+
+## REQUIRED elements:
+- [Same detailed bullet format as above]
+
+## Integration approach:
+[Same spatial layout instruction]
+```
+
+### Reference Analysis Template
+
+Use this format when analyzing reference images. Extract **specific, concrete, reproducible** details — not vague summaries.
+
+| Aspect | Analysis Points | Good Example | Bad Example |
+|--------|-----------------|--------------|-------------|
+| **Brand elements** | Logos, wordmarks, distinctive typography | "Logo 'm' formed by 3 vertical lines" | "Has a logo" |
+| **Signature patterns** | Unique motifs, textures, geometric patterns | "Woven curves forming diamond grid" | "Has patterns" |
+| **Colors** | Exact hex values or close approximations | "#2D4A3E dark teal, #F5F0E0 cream" | "Dark and light" |
+| **Layout** | Spatial zones, banner placement, proportions | "Bottom 30% is dark banner with branding" | "Has a banner" |
+| **Typography** | Font style, weight, case, spacing, position | "Uppercase, wide letter-spacing, right-aligned" | "Has text" |
+| **Rendering** | Line quality, texture, depth treatment | "Topographic contour lines as background texture" | "Clean style" |
+| **Elements** | Icon vocabulary, decorative motifs | "Geometric intersecting line ornaments at corners" | "Has decorations" |
+
+**Output**: Each extracted element should be written as a **copy-pasteable prompt instruction** prefixed with "MUST" or "REQUIRED".

+# Reference Image Handling
+
+Guide for processing user-provided reference images in cover generation.
+
+## Input Detection
+
+| Input Type | Action |
+|------------|--------|
+| Image file path provided | Copy to `refs/` → can use `--ref` |
+| Image in conversation (no path) | **ASK user for file path** with AskUserQuestion |
+| User can't provide path | Extract style/palette verbally → append to prompt (NO frontmatter references) |
+
+**CRITICAL**: Only add `references` to prompt frontmatter if files are ACTUALLY SAVED to `refs/` directory.
+
+## File Saving
+
+**If user provides file path**:
+1. Copy to `refs/ref-NN-{slug}.{ext}` (NN = 01, 02, ...)
+2. Create description: `refs/ref-NN-{slug}.md`
+3. Verify files exist before proceeding
+
+**Description File Format**:
+```yaml
+---
+ref_id: NN
+filename: ref-NN-{slug}.{ext}
+usage: direct | style | palette
+---
+[User's description or auto-generated description]
+```
+
+| Usage | When to Use |
+|-------|-------------|
+| `direct` | Reference matches desired output closely |
+| `style` | Extract visual style characteristics only |
+| `palette` | Extract color scheme only |
+
+## Verbal Extraction (No File)
+
+When user can't provide file path:
+1. Analyze image visually, extract: colors, style, composition
+2. Create `refs/extracted-style.md` with extracted info
+3. DO NOT add `references` to prompt frontmatter
+4. Append extracted style/colors directly to prompt text
+
+## Deep Analysis ⚠️ CRITICAL
+
+References are high-priority inputs. Extract **specific, concrete, reproducible** elements:
+
+| Analysis | Description | Example (good vs bad) |
+|----------|-------------|----------------------|
+| **Brand elements** | Logos, wordmarks, specific typography | Good: "Logo uses vertical parallel lines for 'm'" / Bad: "Has a logo" |
+| **Signature patterns** | Unique decorative motifs, textures | Good: "Woven intersecting curves forming diamond grid" / Bad: "Has patterns" |
+| **Color palette** | Exact hex values for key colors | Good: "#2D4A3E dark teal, #F5F0E0 cream" / Bad: "Dark and light colors" |
+| **Layout structure** | Specific spatial arrangement | Good: "Bottom 30% dark banner with branding" / Bad: "Has a banner" |
+| **Typography** | Font style, weight, spacing, case | Good: "Uppercase, wide letter-spacing" / Bad: "Has text" |
+| **Content/subject** | What the reference depicts | Factual description |
+| **Usage recommendation** | `direct` / `style` / `palette` | Based on analysis |
+
+**Output format**: List each element as bullet that can be copy-pasted into prompt as mandatory instruction.
+
+## Verification Output
+
+**For saved files**:
+```
+Reference Images Saved:
+- ref-01-{slug}.png ✓ (can use --ref)
+- ref-02-{slug}.png ✓ (can use --ref)
+```
+
+**For extracted style**:
+```
+Reference Style Extracted (no file):
+- Colors: #E8756D coral, #7ECFC0 mint...
+- Style: minimal flat vector, clean lines...
+→ Will append to prompt text (not --ref)
+```
+
+## Priority Rules
+
+When user provides references, they are **HIGH PRIORITY**:
+
+- **References override defaults**: If reference conflicts with preferred palette/rendering, reference takes precedence
+- **Concrete > abstract**: Extract specific elements — not vague "clean style"
+- **Mandatory language**: Use "MUST", "REQUIRED" in prompt for reference elements
+- **Visible in output**: Verify elements are present after generation; strengthen prompt if not

+
+### First-Time Setup (BLOCKING)
+
+**CRITICAL**: When EXTEND.md is not found, you **MUST use `AskUserQuestion`** to ask the user for their preferences before creating EXTEND.md. **NEVER** create EXTEND.md with defaults without asking. This is a **BLOCKING** operation — do NOT proceed with any conversion until setup is complete.
+
+Use `AskUserQuestion` with ALL questions in ONE call:
+
+**Question 1** — header: "Media", question: "How to handle images and videos in tweets?"
+- "Ask each time (Recommended)" — After saving markdown, ask whether to download media
+- "Always download" — Always download media to local imgs/ and videos/ directories
+- "Never download" — Keep original remote URLs in markdown
+
+**Question 2** — header: "Output", question: "Default output directory?"
+- "x-to-markdown (Recommended)" — Save to ./x-to-markdown/{username}/{tweet-id}.md
+- (User may choose "Other" to type a custom path)
+
+**Question 3** — header: "Save", question: "Where to save preferences?"
+- "User (Recommended)" — ~/.baoyu-skills/ (all projects)
+- "Project" — .baoyu-skills/ (this project only)
+
+After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

+- Images are saved to `imgs/` next to the markdown file
+- Videos are saved to `videos/` next to the markdown file
+- Markdown media links are rewritten to local relative paths
+
+## Media Download Workflow
+
+Based on `download_media` setting in EXTEND.md:
+
+| Setting | Behavior |
+|---------|----------|
+| `1` (always) | Run script with `--download-media` flag |
+| `0` (never) | Run script without `--download-media` flag |
+| `ask` (default) | Follow the ask-each-time flow below |
+
+### Ask-Each-Time Flow
+
+1. Run script **without** `--download-media` → markdown saved
+2. Check saved markdown for remote media URLs (`https://` in image/video links)
+3. **If no remote media found** → done, no prompt needed
+4. **If remote media found** → use `AskUserQuestion`:
+   - header: "Media", question: "Download N images/videos to local files?"
+   - "Yes" — Download to local directories
+   - "No" — Keep remote URLs
+5. If user confirms → run script **again** with `--download-media` (overwrites markdown with localized links)
+
 ## Authentication
 
-**Option 1**: Environment variables (recommended)
-- `X_AUTH_TOKEN` - auth_token cookie
-- `X_CT0` - ct0 cookie
-
-**Option 2**: Chrome login (auto if env vars not set)
-- First run opens Chrome for login
-- Cookies cached locally
+1. **Environment variables** (preferred): `X_AUTH_TOKEN`, `X_CT0`
+2. **Chrome login** (fallback): Auto-opens Chrome, caches cookies locally

+
+# First-Time Setup
+
+## Overview
+
+When no EXTEND.md is found, guide user through preference setup.
+
+**BLOCKING OPERATION**: This setup MUST complete before ANY other workflow steps. Do NOT:
+- Start converting tweets or articles
+- Ask about URLs or output paths
+- Proceed to any conversion
+
+ONLY ask the questions in this setup flow, save EXTEND.md, then continue.
+
+## Setup Flow
+
+```
+No EXTEND.md found
+        |
+        v
++---------------------+
+| AskUserQuestion     |
+| (all questions)     |
++---------------------+
+        |
+        v
++---------------------+
+| Create EXTEND.md    |
++---------------------+
+        |
+        v
+    Continue conversion
+```
+
+## Questions
+
+**Language**: Use user's input language or saved language preference.
+
+Use AskUserQuestion with ALL questions in ONE call:
+
+### Question 1: Download Media
+
+```yaml
+header: "Media"
+question: "How to handle images and videos in tweets?"
+options:
+  - label: "Ask each time (Recommended)"
+    description: "After saving markdown, ask whether to download media"
+  - label: "Always download"
+    description: "Always download media to local imgs/ and videos/ directories"
+  - label: "Never download"
+    description: "Keep original remote URLs in markdown"
+```
+
+### Question 2: Default Output Directory
+
+```yaml
+header: "Output"
+question: "Default output directory?"
+options:
+  - label: "x-to-markdown (Recommended)"
+    description: "Save to ./x-to-markdown/{username}/{tweet-id}.md"
+```
+
+Note: User will likely choose "Other" to type a custom path.
+
+### Question 3: Save Location
+
+```yaml
+header: "Save"
+question: "Where to save preferences?"
+options:
+  - label: "User (Recommended)"
+    description: "~/.baoyu-skills/ (all projects)"
+  - label: "Project"
+    description: ".baoyu-skills/ (this project only)"
+```
+
+## Save Locations
+
+| Choice | Path | Scope |
+|--------|------|-------|
+| User | `~/.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md` | All projects |
+| Project | `.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md` | Current project |
+
+## After Setup
+
+1. Create directory if needed
+2. Write EXTEND.md
+3. Confirm: "Preferences saved to [path]"
+4. Continue with conversion using saved preferences
+
+## EXTEND.md Template
+
+```md
+download_media: [ask/1/0]
+default_output_dir: [path or empty]
+```
+
+## Modifying Preferences Later
+
+Users can edit EXTEND.md directly or delete it to trigger setup again.

+## Usage
+
+Claude performs content analysis and formatting (Steps 1-6), then runs the script for typography fixes (Step 7).
+
+## Workflow
+
+### Step 1: Read Source File
+
+Read the user-specified markdown or plain text file.
+
+### Step 1.5: Detect Content Type & Confirm
+
+**Content Type Detection:**
+
+| Indicator | Classification |
+|-----------|----------------|
+| Has `---` YAML frontmatter | Markdown |
+| Has `#`, `##`, `###` headings | Markdown |
+| Has `**bold**`, `*italic*` | Markdown |
+| Has `- ` or `1. ` lists | Markdown |
+| Has ``` code blocks | Markdown |
+| Has `> ` blockquotes | Markdown |
+| None of above | Plain text |
+
+**Decision Flow:**
+
+┌─────────────────┬────────────────────────────────────────────────┐
+│  Content Type   │                     Action                     │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Plain text      │ Proceed to Step 2 (format to markdown)         │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Markdown        │ Use AskUserQuestion to confirm optimization    │
+└─────────────────┴────────────────────────────────────────────────┘
+
+**If Markdown detected, ask user:**
+
+```
+Detected existing markdown formatting. What would you like to do?
+
+1. Optimize formatting (Recommended)
+   - Add/improve frontmatter, headings, bold, lists
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+2. Keep original formatting
+   - Preserve existing markdown structure
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+3. Typography fixes only
+   - Run typography script on original file in-place
+   - No copy created, modifies original file directly
+```
+
+**Based on user choice:**
+- **Optimize**: Continue to Step 2-8 (full workflow)
+- **Keep original**: Skip Steps 2-5, copy file → Step 6-8 (run script on copy)
+- **Typography only**: Skip Steps 2-6, run Step 7 on original file directly
+
+### Step 2: Analyze Content Structure
+
+Identify:
+- Existing title (H1 `#`)
+- Paragraph separations
+- Keywords suitable for **bold**
+- Parallel content convertible to lists
+- Code snippets
+- Quotations
+
+### Step 3: Check/Create Frontmatter
+
+Check for YAML frontmatter (`---` block). Create if missing.
+
+**Meta field handling:**
+
+| Field | Processing |
+|-------|------------|
+| `title` | See Step 4 |
+| `slug` | Infer from file path (e.g., `posts/2026/01/10/vibe-coding/` → `vibe-coding`) or generate from title |
+| `summary` | Generate engaging summary (100-150 characters) |
+| `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path (also accepted: `featureImage`) |
+
+### Step 4: Title Handling
+
+**Logic:**
+1. If frontmatter already has `title` → use it, no H1 in body
+2. If first line is H1 → extract to frontmatter `title`, remove H1 from body
+3. If neither exists → generate candidate titles
+
+**Title generation flow:**
+
+1. Generate 3 candidate titles based on content
+2. Use `AskUserQuestion` tool:
+
+```
+Select a title:
+
+1. [Title A] (Recommended)
+2. [Title B]
+3. [Title C]
+```
+
+3. If no selection within a few seconds, use recommended (option 1)
+
+**Title principles:**
+- Concise, max 20 characters
+- Captures core message
+- Engaging, sparks reading interest
+- Accurate, avoids clickbait
+
+**Important:** Once title is in frontmatter, body should NOT have H1 (avoid duplication)
+
+### Step 5: Format Processing
+
+**Formatting rules:**
+
+| Element | Format |
+|---------|--------|
+| Titles | Use `#`, `##`, `###` hierarchy |
+| Key points | Use `**bold**` |
+| Parallel items | Convert to `-` unordered or `1.` ordered lists |
+| Code/commands | Use `` `inline` `` or ` ```block``` ` |
+| Quotes/sayings | Use `>` blockquote |
+| Separators | Use `---` where appropriate |
+
+**Formatting principles:**
+- Preserve original content and viewpoints
+- Add formatting only, do not modify text
+- Formatting serves readability
+- Avoid over-formatting
+
+### Step 6: Save Formatted File
+
+Save as `{original-filename}-formatted.md`
+
+Examples:
+- `final.md` → `final-formatted.md`
+- `draft-v1.md` → `draft-v1-formatted.md`
+
+**If user chose "Keep original formatting" (from Step 1.5):**
+- Copy original file to `{filename}-formatted.md` without modifications
+- Proceed to Step 7 for typography fixes only
+
+**Backup existing file:**
+
+If `{filename}-formatted.md` already exists, backup before overwriting:
+
+```bash
+# Check if formatted file exists
+if [ -f "{filename}-formatted.md" ]; then
+  # Backup with timestamp
+  mv "{filename}-formatted.md" "{filename}-formatted.backup-$(date +%Y%m%d-%H%M%S).md"
+fi
+```
+
+Example:
+- `final-formatted.md` exists → backup to `final-formatted.backup-20260128-143052.md`
+
+### Step 7: Execute Text Formatting Script
+
+After saving, **must** run the formatting script:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts {output-file-path} [options]
+```
+
+**Script Options:**
+
+| Option | Short | Description | Default |
+|--------|-------|-------------|---------|
+| `--quotes` | `-q` | Replace ASCII quotes with fullwidth quotes `"..."` | false |
+| `--no-quotes` | | Do not replace quotes | |
+| `--spacing` | `-s` | Add CJK/English spacing via autocorrect | true |
+| `--no-spacing` | | Do not add CJK/English spacing | |
+| `--emphasis` | `-e` | Fix CJK emphasis punctuation issues | true |
+| `--no-emphasis` | | Do not fix CJK emphasis issues | |
+| `--help` | `-h` | Show help message | |
+
+**Examples:**
+
+```bash
+# Default: spacing + emphasis enabled, quotes disabled
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md
+
+# Enable all features including quote replacement
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --quotes
+
+# Only fix emphasis issues, skip spacing
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing
+
+# Disable all processing except frontmatter formatting
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing --no-emphasis
+```
+
+**Script performs (based on options):**
+1. Fix CJK emphasis/bold punctuation issues (default: enabled)
+2. Add CJK/English mixed text spacing via autocorrect (default: enabled)
+3. Replace ASCII quotes `"..."` with fullwidth quotes `"..."` (default: disabled)
+4. Format frontmatter YAML (always enabled)
+
+### Step 8: Display Results
+
+```
+**Formatting complete**
+
+File: posts/2026/01/09/example/final-formatted.md
+
+Changes:
+- Added title: [title content]
+- Added X bold markers
+- Added X lists
+- Added X code blocks
+```
+
+## Formatting Example
+
+**Before:**
+```
+This is plain text. First point is efficiency improvement. Second point is cost reduction. Third point is experience optimization. Use npm install to install dependencies.
+```
+
+**After:**
+```markdown
+---
+title: Three Core Advantages
+slug: three-core-advantages
+summary: Discover the three key benefits that drive success in modern projects.
+---
+
+This is plain text.
+
+**Main advantages:**
+- Efficiency improvement
+- Cost reduction
+- Experience optimization
+
+Use `npm install` to install dependencies.
+```
+
+## Notes
+
+- Preserve original writing style and tone
+- Specify correct language for code blocks (e.g., `python`, `javascript`)
+- Maintain CJK/English spacing standards
+- Do not add content not present in original
+
+## Extension Support
+
+Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.

-## Provider & Model Strategy
+## Provider Selection
 
-### Auto-Selection
-
-1. If `--provider` specified → use it
-2. If only one API key available → use that provider
-3. If both available → default to Google (multimodal LLMs more versatile)
-
-### API Selection by Model Type
-
-| Model Category | API Function | Example Models |
-|----------------|--------------|----------------|
-| Google Multimodal | `generateText` | `gemini-2.0-flash-exp-image-generation` |
-| Google Imagen | `experimental_generateImage` | `imagen-3.0-generate-002` |
-| OpenAI | `experimental_generateImage` | `gpt-image-1`, `dall-e-3` |
-
-### Available Models
-
-**Google**:
-- `gemini-3-pro-image-preview` - Default, multimodal generation
-- `gemini-2.0-flash-exp-image-generation` - Gemini 2.0 Flash
-- `imagen-3.0-generate-002` - Imagen 3
-
-**OpenAI**:
-- `gpt-image-1.5` - Default, GPT Image 1.5
-- `gpt-image-1` - GPT Image 1
-- `dall-e-3` - DALL-E 3
+1. `--ref` provided + no `--provider` → auto-select Google first, then OpenAI
+2. `--provider` specified → use it (if `--ref`, must be `google` or `openai`)
+3. Only one API key available → use that provider
+4. Multiple available → default to Google
 
 ## Quality Presets
 
-| Preset | OpenAI | Google | Use Case |
-|--------|--------|--------|----------|
-| `normal` | 1024x1024 | Default | Covers, illustrations |
-| `2k` | 2048x2048 | "2048px" in prompt | Infographics, slides |
+| Preset | Google imageSize | OpenAI Size | Use Case |
+|--------|------------------|-------------|----------|
+| `normal` | 1K | 1024px | Quick previews |
+| `2k` (default) | 2K | 2048px | Covers, illustrations, infographics |
 
-## Aspect Ratio Handling
+**Google imageSize**: Can be overridden with `--imageSize 1K|2K|4K`
 
-- **Multimodal LLMs**: Embedded in prompt (e.g., `"... aspect ratio 16:9"`)
-- **Image-only models**: Uses `aspectRatio` or `size` parameter
-- **Common ratios**: 1:1, 16:9, 9:16, 4:3, 3:4, 2.35:1
+## Aspect Ratios
 
-## Examples
+Supported: `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `2.35:1`
 
-### Generate Cover Image
+- Google multimodal: uses `imageConfig.aspectRatio`
+- Google Imagen: uses `aspectRatio` parameter
+- OpenAI: maps to closest supported size
 
-```bash
-npx -y bun ${SKILL_DIR}/scripts/main.ts \
-  --prompt "A minimalist tech illustration with blue gradients" \
-  --image cover.png --ar 2.35:1 --quality 2k
+## Generation Mode
+
+**Default**: Sequential generation (one image at a time). This ensures stable output and easier debugging.
+
+**Parallel Generation**: Only use when user explicitly requests parallel/concurrent generation.
+
+| Mode | When to Use |
+|------|-------------|
+| Sequential (default) | Normal usage, single images, small batches |
+| Parallel | User explicitly requests, large batches (10+) |
+
+**Parallel Settings** (when requested):
+
+| Setting | Value |
+|---------|-------|
+| Recommended concurrency | 4 subagents |
+| Max concurrency | 8 subagents |
+| Use case | Large batch generation when user requests parallel |
+
+**Agent Implementation** (parallel mode only):
 ```
-
-### Generate Social Media Post
-
-```bash
-npx -y bun ${SKILL_DIR}/scripts/main.ts \
-  --prompt "Instagram post about coffee" \
-  --image post.png --ar 1:1
-```
-
-### Edit Image with Reference
-
-```bash
-npx -y bun ${SKILL_DIR}/scripts/main.ts \
-  --prompt "Change the background to sunset" \
-  --image edited.png --ref original.png --provider google
-```
-
-### Batch Generation from Prompt File
-
-```bash
-# Create prompt file with detailed instructions
-npx -y bun ${SKILL_DIR}/scripts/main.ts \
-  --promptfiles style-guide.md scene-description.md \
-  --image scene.png
+# Launch multiple generations in parallel using Task tool
+# Each Task runs as background subagent with run_in_background=true
+# Collect results via TaskOutput when all complete
 ```
 
 ## Error Handling
 
-- **Missing API key**: Clear error with setup instructions
-- **Generation failure**: Auto-retry once, then error
-- **Invalid aspect ratio**: Warning, proceed with default
-- **Reference images with image-only model**: Warning, ignore refs
+- Missing API key → error with setup instructions
+- Generation failure → auto-retry once
+- Invalid aspect ratio → warning, proceed with default
+- Reference images with unsupported provider/model → error with fix hint (switch to Google multimodal or OpenAI GPT Image edits)
 
 ## Extension Support
 
-Custom configurations via EXTEND.md.
-
-**Check paths** (priority order):
-1. `.baoyu-skills/baoyu-image-gen/EXTEND.md` (project)

-**Slug Generation**:
-1. Extract main topic from content (2-4 words, kebab-case)
-2. Example: "Machine Learning Basics" → `ml-basics`
+Slug: 2-4 words kebab-case from topic. Conflict: append `-YYYYMMDD-HHMMSS`.
 
-**Conflict Resolution**:
-If `infographic/{topic-slug}/` already exists:
-- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
-- Example: `ml-basics` exists → `ml-basics-20260120-103052`
+## Core Principles
 
-## Instructional Design Approach
-
-This skill applies a **world-class instructional designer** mindset to infographic creation:
-
-1. **Deep Understanding**: Read and comprehend the source material thoroughly
-2. **Learning Objectives**: Identify what the viewer should understand after seeing the infographic
-3. **Information Architecture**: Structure content for maximum clarity and retention
-4. **Visual Storytelling**: Use visuals to communicate complex ideas accessibly
-5. **Verbatim Data**: Preserve all source data exactly as written—no summarization or rephrasing of facts
+- Preserve all source data **verbatim**—no summarization or rephrasing
+- Define learning objectives before structuring content
+- Structure for visual communication (headlines, labels, visual elements)
 
 ## Workflow
 
-### Step 1: Analyze Content → `analysis.md`
+### Step 1: Setup & Analyze
 
-Read source content and perform deep instructional analysis.
+**1.1 Load Preferences (EXTEND.md)**
 
-**Actions**:
-1. **Save source content** (if not already a file):
-   - If user provides a file path: use as-is
-   - If user pastes content: save to `source.md` in target directory
+Use Bash to check EXTEND.md existence (priority order):
 
-2. **Deep reading**:
-   - Read the entire document thoroughly
-   - Develop deep understanding before proceeding
-   - Identify the core message and purpose
+```bash
+# Check project-level first
+test -f .baoyu-skills/baoyu-infographic/EXTEND.md && echo "project"
 
-3. **Content analysis**:
-   | Aspect | Questions to Answer |
-   |--------|---------------------|
-   | **Main Topic** | What is this content fundamentally about? |
-   | **Data Type** | Timeline? Hierarchy? Comparison? Process? Relationships? |
-   | **Complexity** | Simple (3-5 points) or complex (6-10+ points)? |
-   | **Tone** | Technical, educational, playful, serious, persuasive? |
-   | **Audience** | Who is the intended viewer? What do they already know? |
-
-4. **Language detection**:
-   - Detect **source language** from content
-   - Detect **user language** from conversation
-   - Note if source_language ≠ user_language (will ask in Step 4)
-
-5. **Extract design instructions** from user input:
-   - Style preferences (colors, mood, aesthetic)
-   - Layout preferences (structure, organization)
-   - Any specific visual requirements
-   - Separate these from content—they go in the Design Instructions section
-
-6. **Save to `analysis.md`**
-
-**Analysis Output Format**:
-```yaml
----
-title: "[Main topic title]"
-topic: "[Category: educational/technical/business/etc.]"
-data_type: "[timeline/hierarchy/comparison/process/etc.]"
-complexity: "[simple/moderate/complex]"

+
+Schema: `references/config/preferences-schema.md`
+
+**1.2 Analyze Content → `analysis.md`**
+
+1. Save source content (file path or paste → `source.md`)
+   - **Backup rule**: If `source.md` exists, rename to `source-backup-YYYYMMDD-HHMMSS.md`
+2. Analyze: topic, data type, complexity, tone, audience
+3. Detect source language and user language
+4. Extract design instructions from user input
+5. Save analysis
+   - **Backup rule**: If `analysis.md` exists, rename to `analysis-backup-YYYYMMDD-HHMMSS.md`
+
+See `references/analysis-framework.md` for detailed format.
+
 ### Step 2: Generate Structured Content → `structured-content.md`
 
-Transform analyzed content into a structured format for the infographic designer.
+Transform content into infographic structure:
+1. Title and learning objectives
+2. Sections with: key concept, content (verbatim), visual element, text labels
+3. Data points (all statistics/quotes copied exactly)
+4. Design instructions from user
 
-**Instructional Design Process**:
+**Rules**: Markdown only. No new information. All data verbatim.
 
-1. **Create high-level outline**:
-   - Title that captures the essence
-   - List all main learning objectives
-   - Identify the logical flow
+See `references/structured-content-template.md` for detailed format.
 
-2. **Flesh out each section**:
-   - For each learning objective, create a section
-   - Mix conceptual explanations with practical elements
-   - Preserve all source data **verbatim**—do not summarize or rephrase
+### Step 3: Recommend Combinations
 
-3. **Structure for visual communication**:
-   - Identify what becomes a headline
-   - Identify what becomes supporting text
-   - Identify what becomes a visual element
-   - Identify data points, statistics, or quotes
-
-**Critical Rules**:
-| Rule | Requirement |
-|------|-------------|
-| **Output format** | Markdown only |
-| **Tone** | Expert trainer: knowledgeable, clear, encouraging |
-| **No new information** | Do not add anything not in the source |
-| **Verbatim data** | All statistics, quotes, and facts copied exactly |
-
-**Structured Content Format**:
-```markdown
-# [Infographic Title]
-
-## Overview
-[Brief description of what this infographic conveys]
-
-## Learning Objectives
-The viewer will understand:
-1. [Objective 1]
-2. [Objective 2]
-3. [Objective 3]
-
----
-
-## Section 1: [Section Title]
-
-**Key Concept**: [One-sentence summary]
-
-**Content**:
-- [Point 1 - verbatim from source]
-- [Point 2 - verbatim from source]
-- [Point 3 - verbatim from source]
-
-**Visual Element**: [What to show visually]
-
-**Text Labels**:
-- Headline: "[Exact text for headline]"
-- Subhead: "[Exact text for subhead]"
-- Labels: "[Label 1]", "[Label 2]", ...
-
----
-
-## Section 2: [Section Title]
-[Continue pattern...]
-
----
-
-## Data Points (Verbatim)
-[All statistics, numbers, quotes exactly as they appear in source]
-- "[Exact quote or statistic 1]"
-- "[Exact quote or statistic 2]"
-
----
-
-## Design Instructions
-[Extracted from user's steering prompt]
-- Style: [preferences]
-- Colors: [preferences]
-- Layout: [preferences]
-- Other: [any other visual requirements]
-```
-
-### Step 3: Generate Layout×Style Recommendations
-
-Based on analysis and structured content, recommend 3-5 combinations.
-
-**Selection Criteria**:
-| Factor | How to Match |
-|--------|--------------|
-| **Data structure** | Timeline→linear-progression, Hierarchy→hierarchical-layers, etc. |
-| **Content tone** | Technical→technical-schematic, Playful→kawaii, etc. |
-| **Audience** | Business→corporate-memphis, Educational→chalkboard, etc. |
-| **Complexity** | Simple→sparse layouts, Complex→dense layouts |
-| **User preferences** | Honor any design instructions from Step 1 |
-
-**Format each recommendation**:
-```
-[Layout] + [Style]: [Brief rationale based on content analysis]
-```
+Recommend 3-5 layout×style combinations based on:
+- Data structure → matching layout
+- Content tone → matching style
+- Audience expectations
+- User design instructions
 
 ### Step 4: Confirm Options
 
-**IMPORTANT**: Present ALL options in a single confirmation step using AskUserQuestion.
+Use **single AskUserQuestion call** with multiple questions to confirm all options together:
 
-**Questions to ask**:
+| Question | When | Options |
+|----------|------|---------|
+| **Combination** | Always | 3+ layout×style combos with rationale |
+| **Aspect** | Always | landscape (16:9), portrait (9:16), square (1:1) |
+| **Language** | Only if source ≠ user language | Language for text content |
 
-| Question | When to Ask |
-|----------|-------------|
-| Combination | Always (required) |
-| Aspect ratio | Always |
-| Language | Only if `source_language ≠ user_language` |
-
-**AskUserQuestion format**:
-
-**Question 1 (Combination)** - always:
-- Option A (Recommended): [layout] + [style] - [brief rationale]
-- Option B: [layout] + [style] - [brief rationale]
-- Option C: [layout] + [style] - [brief rationale]
-- Custom: Specify your own layout and/or style
-
-**Question 2 (Aspect)** - always:
-- landscape (16:9, Recommended) - standard presentation
-- portrait (9:16) - mobile/social media
-- square (1:1) - social media posts
-
-**Question 3 (Language)** - only if source ≠ user language:
-- [Source language] (matches content)
-- [User language] (your preference)
-
-**Language handling**:
-- If source language = user language: Just inform user
-- If different: Ask which language to use for all text
+**Important**: Do NOT split into separate AskUserQuestion calls. Combine all applicable questions into one call.
 
 ### Step 5: Generate Prompt → `prompts/infographic.md`
 
-Create the image generation prompt.
+**Backup rule**: If `prompts/infographic.md` exists, rename to `prompts/infographic-backup-YYYYMMDD-HHMMSS.md`
 
-**Process**:
-1. Read layout definition from `references/layouts/<layout>.md`
-2. Read style definition from `references/styles/<style>.md`
-3. Read base prompt template from `references/base-prompt.md`
-4. Combine with structured content from Step 2
-5. **All text in prompt uses confirmed language**
-
-**Prompt Structure**:
-```markdown
-Topic: [main topic from analysis]
-Layout: [selected layout]
-Style: [selected style]
-Aspect: [confirmed ratio]
-Language: [confirmed language]
-
-## Layout Guidelines
-[From layout definition file]
-
-## Style Guidelines
-[From style definition file]
-
-## Content to Visualize
-
-### Learning Objectives
-[From structured-content.md]
-
-### Sections
-[From structured-content.md - each section with its visual elements]
-
-### Data Points (Verbatim)
-[All exact statistics, quotes, and facts from source]
-
-## Text Labels (in [language])
-[All text that appears in the infographic, organized by section]
-
-## Design Instructions
-[Any specific visual requirements from user's steering prompt]
-```
+Combine:
+1. Layout definition from `references/layouts/<layout>.md`
+2. Style definition from `references/styles/<style>.md`
+3. Base template from `references/base-prompt.md`
+4. Structured content from Step 2
+5. All text in confirmed language
 
 ### Step 6: Generate Image
 
-**Image Generation Skill Selection**:
-1. Check available image generation skills
-2. If multiple skills available, ask user to choose
-
-**Generation**:
-Call selected image generation skill with:
