-### 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 **If README is outdated**: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"

-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
-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"
+# Example: ALWAYS include --ref for consistency
+npx -y bun ${SKILL_DIR}/../baoyu-image-gen/scripts/main.ts \
+  --promptfiles prompts/01-page-xxx.md \
+  --image 01-page-xxx.png --ar 3:4 \
+  --ref characters/characters.png

-├─ 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 `references/config/first-time-setup.md`)
-3. Create EXTEND.md at user-chosen location
-4. Confirm: "✓ Preferences saved to [path]"
+| Path | Location |
+|------|----------|
+| `.baoyu-skills/baoyu-comic/EXTEND.md` | Project directory |
+| `$HOME/.baoyu-skills/baoyu-comic/EXTEND.md` | User home |

 **EXTEND.md Supports**: Watermark | Preferred art/tone/layout | Custom style definitions | Character presets | Language preference

-Schema: `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.

+```
+
+---
+
+## 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"
+```

+
+**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

 ## File Structure

-Each session creates an independent directory named by content slug:
+Output directory depends on `default_output_dir` preference:
+
+| Preference | Output Path |
+|------------|-------------|
+| `same-dir` | `{article-dir}/` |
+| `imgs-subdir` | `{article-dir}/imgs/` |
+| `independent` (default) | `cover-image/{topic-slug}/` |
+| Pasted content | `cover-image/{topic-slug}/` (always) |

 ```
-cover-image/{topic-slug}/
+<output-dir>/
 ├── source-{slug}.{ext}    # Source files (text, images, etc.)
 ├── prompts/cover.md       # Generation prompt
 └── cover.png              # Output image
 ```

-**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 `cover-image/{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`, `source-reference.png`, etc.
- Multiple sources supported: text, images, files from conversation
+**Slug**: Extract main topic (2-4 words, kebab-case). Example: "The Future of AI" → `future-of-ai`

 ### Step 1: Analyze Content

-Read source content, save it if needed, and perform 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. **Content analysis**:
-   - Extract: topic, core message, tone, keywords
-   - Identify visual metaphor opportunities
-   - Detect content type (technical/personal/business/creative)
-4. **Language detection**:
-   - Detect source content language
-   - Note user's input language (from conversation)
-   - Compare with language preference in EXTEND.md
+1. **Save source content** (if pasted, save to `source.md` in target directory; if file path, use as-is)
+2. **Content analysis**: Extract topic, core message, tone, keywords; identify visual metaphors; detect content type
+3. **Language detection**: Detect source language, note user's input language, compare with EXTEND.md preference
+4. **Determine output directory** per File Structure rules. If no `default_output_dir` preference + file path input, include in Step 2 Q4

 ### Step 2: Confirm Options ⚠️

-**Purpose**: Validate type, style and aspect ratio. **Do NOT skip.**
+Validate all 5 dimensions + aspect ratio. Full confirmation flow: [references/workflow/confirm-options.md](references/workflow/confirm-options.md)

-**Language**: Auto-determined (user's input language > saved preference > source language). No need to ask.
+**Skip Conditions**:

-Present options using AskUserQuestion:
-
-**Question 1: Type** (if not specified via `--type`)
- Show recommended type based on content analysis + preferred type from EXTEND.md
-
-```yaml
-header: "Type"
-question: "Which cover type?"
-multiSelect: false
-options:
-  - label: "[auto-recommended type] (Recommended)"
-    description: "[reason based on content signals]"

-  - label: "conceptual"
-    description: "Concept visualization - technical, architecture"
-  - label: "typography"
-    description: "Text-focused layout - opinions, quotes"
-```
-
-**Question 2: Style** (if not specified via `--style`)
- Based on selected Type, show compatible styles (✓✓ first from compatibility matrix)
- Format: `[style name] - [why it fits this content]`
-
-```yaml
-header: "Style"
-question: "Which cover style?"
-multiSelect: false
-options:
-  - label: "[best compatible style] (Recommended)"
-    description: "[reason based on type + content]"
-  - label: "[style2]"
-    description: "[reason]"
-  - label: "[style3]"
-    description: "[reason]"
-```
-
-**Question 3: Aspect Ratio** (if not specified via `--aspect`)
-
-```yaml
-header: "Aspect"
-question: "Cover aspect ratio?"
-multiSelect: false
-options:
-  - label: "2.35:1 (Recommended)"
-    description: "Cinematic widescreen, best for article headers"
-  - label: "16:9"
-    description: "Standard widescreen, versatile"
-  - label: "1:1"
-    description: "Square, social media friendly"
-```
-
-**After response**: Proceed to Step 3 with confirmed type + style + aspect ratio.
+| Condition | Skipped | Still Asked |
+|-----------|---------|-------------|
+| `--quick` or `quick_mode: true` | 5 dimensions | Aspect ratio (unless `--aspect`) |
+| All 5 + `--aspect` specified | All | None |

-Type notes: [key characteristics from type definition]
-Style notes: [key characteristics from style definition]
-
-[Watermark section if enabled]
-```
-
-**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** (if included):
- Max 8 characters, punchy headline
- Use hooks: numbers, questions, contrasts
- Match confirmed language
-
-**Watermark Application** (if enabled in preferences):
-Add to prompt:
-```
-Include a subtle watermark "[content]" positioned at [position]
-with approximately [opacity*100]% visibility. The watermark should
-be legible but not distracting from the main content.
-```

- **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**
+- Subtitle: Secondary, max 15 characters (if title-subtitle or text-rich)
+- Tags: 2-4 keyword badges (if text-rich)
+- Font style harmonizes with rendering style
+- **Engagement hooks**: Use numbers ("3个关键"), questions ("Why?"), contrasts ("A vs B"), pain points ("别再X了"), or suspense ("隐藏的X") for compelling titles
+
+## Composition Guidance
+
+**Icon Vocabulary**: Represent concepts with simple, recognizable icons rather than detailed illustrations. Use the rendering style to determine icon complexity (flat-vector = geometric, hand-drawn = sketchy, etc.)
+
+**Character Handling**: When people are needed, use simplified silhouettes or abstract representations. NO realistic faces, detailed anatomy, or photographic representations.
+
+## 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 |

+# Step 2: Confirm Options
+
+## Purpose
+
+Validate all 5 dimensions + aspect ratio.
+
+## Skip Conditions
+
+| Condition | Skipped Questions | Still Asked |
+|-----------|-------------------|-------------|
+| `--quick` flag | Type, Palette, Rendering, Text, Mood | **Aspect Ratio** (unless `--aspect` specified) |
+| All 5 dimensions + `--aspect` specified | All | None |
+| `quick_mode: true` in EXTEND.md | Type, Palette, Rendering, Text, Mood | **Aspect Ratio** (unless `--aspect` specified) |
+| Otherwise | None | All 6 questions |
+
+**Important**: Aspect ratio is ALWAYS asked unless explicitly specified via `--aspect` CLI flag. User presets in EXTEND.md are shown as recommended option, not auto-selected.
+
+## Quick Mode Output
+
+When skipping 5 dimensions:
+
+```
+Quick Mode: Auto-selected dimensions
+• Type: [type] ([reason])
+• Palette: [palette] ([reason])
+• Rendering: [rendering] ([reason])
+• Text: [text] ([reason])
+• Mood: [mood] ([reason])
+
+[Then ask Question 6: Aspect Ratio]
+```
+
+## Confirmation Flow
+
+**Language**: Auto-determined (user's input language > saved preference > source language). No need to ask.
+
+Present ALL options in a **single AskUserQuestion call** (4 questions max).
+
+Skip any question where the dimension is already specified via CLI flag or `--style` preset.

+  - label: "digital"
+    description: "Polished, precise, subtle gradients"
+```
+
+### Q4: Other Settings (skip if all remaining dimensions already specified)
+
+Combine remaining settings into one question. Include: Output Dir (if no preference + file path input), Text, Mood, Aspect. Show auto-selected values as recommended option. User can accept all or type adjustments via "Other".
+
+**When output dir needs asking** (no `default_output_dir` preference + file path input):
+
+```yaml
+header: "Settings"

+  - label: "independent / [auto-text] / [auto-mood] / [preset-aspect]"
+    description: "cover-image/{topic-slug}/, separate from article"

-## ⚠️ Disclaimer (REQUIRED)
+## Consent Check (REQUIRED)

-**Before using this skill**, the consent check MUST be performed.
+Before first use, verify user consent for reverse-engineered API usage.

-### Consent Check Flow
+**Consent file locations**:
+- macOS: `~/Library/Application Support/baoyu-skills/gemini-web/consent.json`
+- Linux: `~/.local/share/baoyu-skills/gemini-web/consent.json`
+- Windows: `%APPDATA%\baoyu-skills\gemini-web\consent.json`

-**Step 1**: Check consent file
-
-```bash
-# macOS
-cat ~/Library/Application\ Support/baoyu-skills/gemini-web/consent.json 2>/dev/null
-
-# Linux
-cat ~/.local/share/baoyu-skills/gemini-web/consent.json 2>/dev/null

-
-Print warning and proceed:
-```
-⚠️  Warning: Using reverse-engineered Gemini Web API (not official). Accepted on: <acceptedAt date>
-```
-
-**Step 3**: If consent file doesn't exist or `disclaimerVersion` mismatch:
-
-Display disclaimer and ask user:
-
-```
-⚠️  DISCLAIMER
-
-This tool uses a reverse-engineered Gemini Web API, NOT an official Google API.
-
-Risks:
- May break without notice if Google changes their API
- No official support or guarantees
- Use at your own risk
-
-Do you accept these terms and wish to continue?
-```
-
-Use `AskUserQuestion` tool with options:
- **Yes, I accept** - Continue and save consent
- **No, I decline** - Exit immediately
-
-**Step 4**: On acceptance, create consent file:
-
-```bash
-# macOS

-## 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
+## Parallel Generation
+
+Supports concurrent image generation via background subagents for batch operations.
+
+| Setting | Value |
+|---------|-------|
+| Recommended concurrency | 4 subagents |
+| Max concurrency | 8 subagents |
+| Use case | Batch generation (slides, comics, infographics) |
+
+**Agent Implementation**:
+```
+# 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
 ```

-### 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
-```
+**Best Practice**: When generating 4+ images, spawn background subagents (recommended 4 concurrent) instead of sequential execution.

 ## 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 non-multimodal model → warning, ignore refs

 ## Extension Support

-**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]"

+
+**1.2 Analyze Content → `analysis.md`**
+
+1. Save source content (file path or paste → `source.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
+
+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.
-
-**Questions to ask**:
-
-| 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
+Present all options in single confirmation:
+1. **Combination** (always): 3+ options with rationale
+2. **Aspect** (always): landscape/portrait/square
+3. **Language** (only if source ≠ user language): which language for text

 ### Step 5: Generate Prompt → `prompts/infographic.md`

-Create the image generation prompt.
-
-**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 determines information architecture; style determines visual treatment
- Default style `craft-handmade` works well with most layouts
- Technical content benefits from `technical-schematic` or `ui-wireframe`
- Educational content works well with `chalkboard`, `storybook-watercolor`
- Business content pairs with `corporate-memphis`, `dashboard`
- All text in the infographic uses the confirmed language
- **Never add information not present in the source document**
- **Statistics and quotes must be copied exactly—no paraphrasing**

+
+### Image-Text (图文)

 ```bash
-# From markdown file and image directory
 npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --markdown article.md --images ./images/
-
-# With explicit parameters
-npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img1.png --image img2.png --submit
+npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit
 ```

-### Article (文章) - Full markdown with formatting
+### Article (文章)

+Before posting, ask user to choose a theme using AskUserQuestion:
+
+| Theme | Description |
+|-------|-------------|
+| `default` | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
+| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 (by @brzhang) |
+| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 (by @okooo5km) |
+
+Default: `default`. If user has already specified a theme, skip the question.
+
+**Workflow**:
+
+1. Generate HTML preview and print the full `htmlPath` from JSON output so user can click to preview:
 ```bash
-# Post markdown article
-npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown article.md --theme grace
+npx -y bun ${SKILL_DIR}/scripts/md-to-wechat.ts article.md --theme <chosen-theme>
+```
+2. Post to WeChat:
+```bash
+npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown article.md --theme <chosen-theme>
 ```

-> **Note**: `${SKILL_DIR}` represents this skill's installation directory. Agent replaces with actual path at runtime.

+# 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 |
+

+### 1. Design Aesthetic
+
+Combine characteristics from all four dimensions into 2-3 sentences:
+
+| Texture | Contribution |
+|---------|--------------|
+| clean | "Clean, digital precision with crisp edges" |
+| grid | "Technical grid overlay with engineering precision" |
+| organic | "Hand-drawn feel with soft textures" |
+| pixel | "Chunky pixel aesthetic with 8-bit charm" |
+| paper | "Aged paper texture with vintage character" |
+
+| Mood | Contribution |
+|------|--------------|
+| professional | "Professional navy and gold palette" |
+| warm | "Warm earth tones creating approachable atmosphere" |
+| cool | "Cool analytical blues and grays" |
+| vibrant | "Bold, high-saturation colors with energy" |
+| dark | "Deep cinematic backgrounds with glowing accents" |
+| neutral | "Minimal grayscale sophistication" |
+
+### 2. Background
+
+From `references/dimensions/texture.md`:
+- Texture description
+- Base color from mood palette
+
+### 3. Typography
+
+From `references/dimensions/typography.md`:
+- Headline visual description (NOT font names)
+- Body text visual description (NOT font names)
+
+**Important**: Describe appearance for image generation: "bold geometric sans-serif with perfect circular O shapes" NOT "Inter font".
+
+### 4. Color Palette
+
+From `references/dimensions/mood.md`:
+- Copy the palette specifications for the selected mood
+- Include hex codes and usage notes
+
+### 5. Visual Elements
+
+Combine texture and mood characteristics:
+
+| Combination | Visual Elements |
+|-------------|-----------------|
+| clean + professional | Clean charts, outlined icons, structured grids |
+| grid + cool | Technical schematics, dimension lines, blueprints |
+| organic + warm | Hand-drawn icons, brush strokes, doodles |
+| pixel + vibrant | Pixel art icons, retro game elements |
+| paper + warm | Vintage stamps, aged elements, sepia overlays |
+
+### 6. Density Guidelines
+
+From `references/dimensions/density.md`:
+- 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
+- organic: Don't use perfect geometry
+- pixel: Don't smooth edges
+- paper: Don't use bright digital colors

 ## 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.
-
-Best for:
- Public pages
- 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
+**Wait mode workflow**:
+1. Run with `--wait` → script outputs "Press Enter when ready"
+2. Ask user to confirm page is ready
+3. Send newline to stdin to trigger capture

 ## Output Format

-```markdown
---
-url: https://example.com/page
-title: "Page Title"
-description: "Meta description if available"
-author: "Author if available"
-published: "2024-01-01"

-## 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

-**Path Components**:
- `<domain>`: Site domain (e.g., `example.com`, `github.com`)
- `<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**:
-If `url-to-markdown/<domain>/<slug>.md` already exists:
- Append timestamp: `<slug>-YYYYMMDD-HHMMSS.md`

安闲静雅	6bfafe0ec5	feat(baoyu-post-to-wechat): reuse existing Chrome instead of requiring all windows closed Previously, the script always launched a new Chrome instance, which failed when Chrome was already running due to profile lock conflicts on macOS. Users had to close all Chrome windows before publishing. This change adds auto-detection of existing Chrome debug ports and reuses an already-logged-in WeChat tab when available, falling back to launching a new instance only when no existing Chrome is found. Changes: - cdp.ts: add tryConnectExisting() and findExistingChromeDebugPort() - wechat-article.ts: try existing Chrome before launching new one, reuse logged-in WeChat tab (identified by token= in URL), add waitForElement() for reliable menu detection, add --cdp-port option for manual override, fix process not exiting after completion Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 13:16:33 +08:00

JadeLiang	5a11b49b00	Fix: Windows compatibility for baoyu-post-to-wechat ## Problem The baoyu-post-to-wechat skill failed on Windows due to: 1. `new URL(import.meta.url).pathname` returns incorrect path format on Windows 2. Copy/paste operations used `xdotool` (Linux tool) which doesn't exist on Windows ## Solution 1. md-to-wechat.ts: Use `fileURLToPath()` to correctly resolve file paths on Windows 2. wechat-article.ts: Use CDP `Input.dispatchKeyEvent` for copy/paste operations - Replaces system-dependent tools (xdotool/osascript) - Works consistently across Windows/macOS/Linux - More reliable as it operates within Chrome session ## Changes - Import `fileURLToPath` from 'node:url' - Replace `new URL(import.meta.url).pathname` with `fileURLToPath(import.meta.url)` - Replace system tool calls with CDP keyboard events for Ctrl+C and Ctrl+V - Add platform-specific modifier handling (Cmd for macOS, Ctrl for Windows/Linux) ## Testing - Tested successfully on Windows 11 - Markdown conversion works correctly - HTML copy/paste to WeChat editor works correctly Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2026-01-25 15:24:04 +08:00
