-### 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
+1. **Identify changed files** per commit
-2. **For each skill/feature changed**, check if README documentation matches:
+2. **Group by skill/module**:
-   - Options/flags documented correctly
+   - `skills/<skill-name>/*` → Group under that skill
-   - Usage examples reflect current syntax
+   - Root files (CLAUDE.md, etc.) → Group as "project"
-   - Feature descriptions are accurate
+   - Multiple skills in one commit → Split into multiple groups
-3. **If README is outdated**:
+3. **For each group**, identify related README updates needed
-   - Update README.md (and README.zh.md if exists) to reflect changes
+
-   - Include in release commit
+**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

+```
+
+### 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

-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**:
+```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 |
 
 ```bash
-# Check project-level first
+# Example: ALWAYS include --ref for consistency
-test -f .baoyu-skills/baoyu-comic/EXTEND.md && echo "project"
+npx -y bun ${SKILL_DIR}/../baoyu-image-gen/scripts/main.ts \
-
+  --promptfiles prompts/01-page-xxx.md \
-# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
+  --image 01-page-xxx.png --ar 3:4 \
-test -f "$HOME/.baoyu-skills/baoyu-comic/EXTEND.md" && echo "user"
+  --ref characters/characters.png
 ```

-└─ 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 `references/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: `references/config/preferences-schema.md`
+Schema: [references/config/preferences-schema.md](references/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
-2. Read source content
-3. **Deep analysis** following `references/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 `references/analysis-framework.md` for full template.
-
-### 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]
-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
-
-## Preset: Ohmsha
-
-Default: Use Doraemon characters (大雄=learner, 哆啦A梦=mentor, 胖虎=challenge, 静香=support). Custom characters via `--characters "Student:小明,Mentor:教授"` or character presets in EXTEND.md.
-
-Requirements: Visual metaphors, NO talking heads, narrative page titles.
-
-See `references/presets/ohmsha.md` and `references/ohmsha-guide.md` for details.

+## Flow Diagram
+
+```
+Input → Preferences → Analyze → [Check Existing?] → [Confirm 1: Style + Reviews] → Storyboard → [Review Outline?] → Prompts → [Review Prompts?] → Images → PDF → Complete
+```
+
+---
+
+## 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
+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`
+
+**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. Generate → `characters/characters.png`
+3. 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. Generate image using Strategy A or B (based on skill capability)
+3. Save to `NN-{cover|page}-[slug].png`
+4. 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

-- **Missing API key**: Clear error with setup instructions
+- Missing API key → error with setup instructions
-- **Generation failure**: Auto-retry once, then error
+- Generation failure → auto-retry once
-- **Invalid aspect ratio**: Warning, proceed with default
+- Invalid aspect ratio → warning, proceed with default
-- **Reference images with image-only model**: Warning, ignore refs
+- Reference images with non-multimodal model → warning, ignore refs

+# Design Guidelines
+
+Detailed design principles for slide decks.
+
+## Audience Guidelines
+
+Design decisions adapt to target audience. Use `--audience` to set.
+
+| Audience | Content Density | Visual Style | Terminology | Slides |
+|----------|-----------------|--------------|-------------|--------|
+| `beginners` | Low | Friendly, illustrative | Plain language | 8-15 |
+| `intermediate` | Medium | Balanced, structured | Some jargon OK | 10-20 |
+| `experts` | High | Data-rich, precise | Technical terms | 12-25 |
+| `executives` | Low-Medium | Clean, impactful | Business language | 8-12 |
+| `general` | Medium | Accessible, engaging | Minimal jargon | 10-18 |
+
+### Audience → Density Mapping
+
+Recommended density dimension based on audience:
+
+| Audience | Recommended Density | Rationale |
+|----------|-------------------|-----------|
+| `executives` | minimal | One insight per slide, respect time |
+| `beginners` | minimal → balanced | Single concepts, build understanding |
+| `general` | balanced | Accessible but informative |
+| `intermediate` | balanced | Standard information density |
+| `experts` | balanced → dense | Can handle more data per slide |
+
+**Automatic Density Selection**:
+- If `--audience executives` → default to `minimal` density
+- If `--audience beginners` → default to `minimal` or `balanced`
+- If `--audience experts` → allow `dense` density
+- Otherwise → default to `balanced`
+
+### Audience-Specific Principles
+
+**Beginners**:
+- One concept per slide
+- Visual metaphors over abstract diagrams
+- Step-by-step progression
+- Generous whitespace
+
+**Experts**:
+- Multiple data points per slide acceptable
+- Technical diagrams with precise labels
+- Assume domain knowledge
+- Dense but organized information
+
+**Executives**:
+- Lead with insights, not data
+- "So what?" on every slide
+- Decision-enabling content
+- Bottom-line upfront (BLUF)
+
+## Visual Hierarchy Principles
+
+| Principle | Description |
+|-----------|-------------|
+| Focal Point | ONE dominant element per slide draws attention first |
+| Rule of Thirds | Position key elements at grid intersections |
+| Z-Pattern | Guide eye: top-left → top-right → bottom-left → bottom-right |
+| Size Contrast | Headlines 2-3x larger than body text |
+| Breathing Room | Minimum 10% margin from all edges |
+
+## Content Density
+
+See `references/dimensions/density.md` for full density dimension specs.
+
+| Level | Description | Use When |
+|-------|-------------|----------|
+| High | Multiple data points, detailed charts, dense text | Expert audience, technical reviews |
+| Medium | Key points with supporting details | General business, mixed audiences |
+| Low | One main idea, large visuals, minimal text | Beginners, keynotes, emotional impact |
+
+**High-Density Principles** (McKinsey-style):
+- Every element earns its space
+- Data speaks louder than decoration
+- Annotations explain insights, not describe data
+- White space is strategic, not filler
+
+**Density by Slide Type**:
+| Slide Type | Recommended Density |
+|------------|-------------------|
+| Cover/Title | minimal |
+| Agenda/Overview | balanced |
+| Content/Analysis | balanced or dense |
+| Data/Metrics | dense |
+| Quote/Impact | minimal |
+| Summary/Takeaway | balanced |
+
+## Color Selection
+
+See `references/dimensions/mood.md` for full mood dimension specs.
+
+**Content-First Approach**:
+1. Analyze content topic, mood, and industry
+2. Consider target audience expectations
+3. Match palette to subject matter
+4. Ensure strong contrast for readability
+
+**Quick Palette Guide**:
+| Content Type | Recommended Mood |
+|--------------|-----------------|
+| Technical/Architecture | cool |
+| Educational/Friendly | warm |
+| Corporate/Professional | professional |
+| Creative/Artistic | vibrant |
+| Scientific/Medical | cool or neutral |
+| Entertainment/Gaming | dark or vibrant |
+
+## Typography Principles
+
+See `references/dimensions/typography.md` for full typography dimension specs.
+
+| Element | Treatment |
+|---------|-----------|
+| Headlines | Bold, 2-3x body size, narrative style |
+| Body Text | Regular weight, readable size |
+| Captions | Smaller, lighter weight |
+| Data Labels | Monospace for technical content |
+| Emphasis | Use bold or color, not underlines |
+
+## Font Recommendations
+
+**English Fonts**:
+| Font | Style | Best For |
+|------|-------|----------|
+| Liter | Sans-serif, geometric | Modern, clean, technical |
+| HedvigLettersSans | Sans-serif, distinctive | Brand-forward, creative |
+| Oranienbaum | High-contrast serif | Elegant, classical |

+- Content per slide limits
+- Whitespace requirements
+- Element count guidelines
+
+### 7. Style Rules
+
+Combine dimension-specific rules:
+
+**Do rules by texture**:
+- clean: Maintain sharp edges, use grid alignment
+- grid: Show precise measurements, use technical diagrams
+- organic: Allow imperfection, layer with subtle overlaps
+- pixel: Keep aliased edges, use chunky elements
+- paper: Add subtle aging effects, use warm tones
+
+**Don't rules by texture**:
+- clean: Don't use hand-drawn elements
+- grid: Don't use organic curves

 ## Capture Modes
 
-### Auto Mode (default)
+| Mode | Behavior | Use When |
+|------|----------|----------|
+| Auto (default) | Capture on network idle | Public pages, static content |
+| Wait (`--wait`) | User signals when ready | Login-required, lazy loading, paywalls |
 
-Page loads → waits for network idle → captures immediately.
+**Wait mode workflow**:
-
+1. Run with `--wait` → script outputs "Press Enter when ready"
-Best for:
+2. Ask user to confirm page is ready
-- Public pages
+3. Send newline to stdin to trigger capture
-- Static content
-- No login required
-
-### Wait Mode (`--wait`)
-
-Page opens → user can interact (login, scroll, etc.) → user signals ready → captures.
-
-Best for:
-- Login-required pages
-- Dynamic content needing interaction
-- Pages with lazy loading
-
-**Agent workflow for wait mode**:
-1. Run script with `--wait` flag
-2. Script outputs: `Page opened. Press Enter when ready to capture...`
-3. Use `AskUserQuestion` to ask user if page is ready
-4. When user confirms, send newline to stdin to trigger capture
 
 ## Output Format
 
-```markdown
+YAML front matter with `url`, `title`, `description`, `author`, `published`, `captured_at` fields, followed by converted markdown content.

-Converted markdown content...
-```
-
-## Mode Selection Guide
-
-When user requests URL capture, help select appropriate mode:
-
-**Suggest Auto Mode when**:
-- URL is public (no login wall visible)
-- Content appears static
-- User doesn't mention login requirements
-
-**Suggest Wait Mode when**:
-- User mentions needing to log in
-- Site known to require authentication
-- User wants to scroll/interact before capture
-- Content is behind paywall
-
-**Ask user when unclear**:
-```
-The page may require login or interaction before capturing.
-
-Which mode should I use?
-1. Auto - Capture immediately when loaded
-2. Wait - Wait for you to interact first
-```

-- `<domain>`: Site domain (e.g., `example.com`, `github.com`)
+- Conflict resolution: Append timestamp `<slug>-YYYYMMDD-HHMMSS.md`
-- `<slug>`: Generated from page title or URL path (kebab-case)
-
-**Slug Generation**:
-1. Extract from page title (preferred) or URL path
-2. Convert to kebab-case, 2-6 words
-3. Example: "Getting Started with React" → `getting-started-with-react`
-
-**Conflict Resolution**:
