- `{article-dir}/` - Same directory as article
- `{article-dir}/imgs/` - Images subdirectory
- `{article-dir}/illustrations/` - Illustrations subdirectory (Recommended)
- `illustrations/{topic-slug}/` - Independent directory
- Save as default - Remember this choice for future runs

 ### Step 2: Setup & Analyze

-**2.1 Analyze Content**
-
 | Analysis | Description |
 |----------|-------------|
 | Content type | Technical / Tutorial / Methodology / Narrative |
+| Illustration purpose | information / visualization / imagination |
 | Core arguments | 2-5 main points to visualize |
 | Visual opportunities | Positions where illustrations add value |
-| Recommended type | Based on content signals |
-| Recommended density | Based on length and complexity |

-**2.2 Extract Core Arguments**
+**CRITICAL**: If article uses metaphors, do NOT illustrate literally. Visualize the **underlying concept**.

- Main thesis
- Key concepts reader needs
- Comparisons/contrasts
- Framework/model proposed
-
-**CRITICAL**: If article uses metaphors (e.g., "电锯切西瓜"), do NOT illustrate literally. Visualize the **underlying concept**.
-
-**2.3 Identify Positions**
-
-**Illustrate**:
- Core arguments (REQUIRED)
- Abstract concepts
- Data comparisons
- Processes, workflows
-
-**Do NOT Illustrate**:
- Metaphors literally
- Decorative scenes
- Generic illustrations

+style: blueprint
+references:                    # ⚠️ ONLY if files EXIST in references/ directory
+  - ref_id: 01

+
+[Type-specific template content below...]
+```
+
+**⚠️ CRITICAL - When to include `references` field**:
+
+| Situation | Action |
+|-----------|--------|
+| Reference file saved to `references/` | Include in frontmatter ✓ |
+| Style extracted verbally (no file) | DO NOT include in frontmatter, append to prompt body instead |
+| File path in frontmatter but file doesn't exist | ERROR - remove references field |
+
+**Reference Usage Types** (only when file exists):
+
+| Usage | Description | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Primary visual reference | Pass to `--ref` parameter |
+| `style` | Style characteristics only | Describe style in prompt text |

+
+STYLE (from reference):
+- Clean lines, minimal shadows
+- Gradient backgrounds
+...
+```
+

+
+## Default Composition Requirements
+
+**Apply to ALL prompts by default**:
+
+| Requirement | Description |
+|-------------|-------------|
+| **Clean composition** | Simple layouts, no visual clutter |
+| **White space** | Generous margins, breathing room around elements |
+| **No complex backgrounds** | Solid colors or subtle gradients only, avoid busy textures |
+| **Centered or content-appropriate** | Main visual elements centered or positioned by content needs |
+| **Matching graphics** | Use graphic elements that align with content theme |
+| **Highlight core info** | White space draws attention to key information |
+
+**Add to ALL prompts**:
+> Clean composition with generous white space. Simple or no background. Main elements centered or positioned by content needs.
+
+---
+
+## Character Rendering
+
+When depicting people:
+
+| Guideline | Description |
+|-----------|-------------|
+| **Style** | Simplified cartoon silhouettes or symbolic expressions |
+| **Avoid** | Realistic human portrayals, detailed faces |
+| **Diversity** | Varied body types when showing multiple people |
+| **Emotion** | Express through posture and simple gestures |
+
+**Add to ALL prompts with human figures**:
+> Human figures: simplified stylized silhouettes or symbolic representations, not photorealistic.
+
+---
+
+## Text in Illustrations
+
+| Element | Guideline |
+|---------|-----------|
+| **Size** | Large, prominent, immediately readable |
+| **Style** | Handwritten fonts preferred for warmth |
+| **Content** | Concise keywords and core concepts only |
+| **Language** | Match article language |
+
+**Add to prompts with text**:
+> Text should be large and prominent with handwritten-style fonts. Keep minimal, focus on keywords.

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

 ### Step 1: Analyze Content

-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
+**1.0 Detect & Save Reference Images** ⚠️ REQUIRED if images provided
+
+Check if user provided reference images. Handle based on input type:
+
+| Input Type | Action |
+|------------|--------|
+| Image file path provided | Copy to `refs/` subdirectory → can use `--ref` |
+| Image in conversation (no path) | **ASK user for file path** with AskUserQuestion |
+| User can't provide path | Extract style/palette verbally → append to prompt (NO frontmatter references) |
+
+**CRITICAL**: Only add `references` to prompt frontmatter if files are ACTUALLY SAVED to `refs/` directory.
+
+**If user provides file path**:
+1. Copy to `refs/ref-NN-{slug}.{ext}` (NN = 01, 02, ...)
+2. Create description: `refs/ref-NN-{slug}.md`
+3. Verify files exist before proceeding
+
+**If user can't provide path** (extracted verbally):
+1. Analyze image visually, extract: colors, style, composition
+2. Create `refs/extracted-style.md` with extracted info
+3. DO NOT add `references` to prompt frontmatter
+4. Instead, append extracted style/colors directly to prompt text
+
+**Description File Format** (only when file saved):
+```yaml
+---
+ref_id: NN
+filename: ref-NN-{slug}.{ext}
+usage: direct | style | palette
+---
+[User's description or auto-generated description]
+```
+
+| Usage | When to Use |
+|-------|-------------|
+| `direct` | Reference matches desired output closely |
+| `style` | Extract visual style characteristics only |
+| `palette` | Extract color scheme only |
+
+**Verification** (only for saved files):
+```
+Reference Images Saved:
+- ref-01-{slug}.png ✓ (can use --ref)
+- ref-02-{slug}.png ✓ (can use --ref)
+```
+
+**Or for extracted style**:
+```
+Reference Style Extracted (no file):
+- Colors: #E8756D coral, #7ECFC0 mint...
+- Style: minimal flat vector, clean lines...
+→ Will append to prompt text (not --ref)
+```
+
+---
+
+**1.1 Save Source Content**
+- If pasted, save to `source.md` in target directory; if file path, use as-is
+- **Backup rule**: If `source.md` exists, rename to `source-backup-YYYYMMDD-HHMMSS.md`
+
+**1.2 Content Analysis**
+- Extract topic, core message, tone, keywords
+- Identify visual metaphors
+- Detect content type
+
+**1.3 Reference Image Analysis** (if provided in Step 1.0)
+
+For each reference image:
+
+| Analysis | Description |
+|----------|-------------|
+| Visual characteristics | Style, colors, composition |
+| Content/subject | What the reference depicts |
+| Style match | Which type/palette/rendering align |
+| Usage recommendation | `direct` / `style` / `palette` |
+
+**1.4 Language Detection**
+- Detect source language
+- Note user's input language
+- Compare with EXTEND.md preference
+
+**1.5 Determine Output Directory**
+- Per File Structure rules
+- If no `default_output_dir` preference + file path input, include in Step 2 Q4

 | Condition | Skipped | Still Asked |
 |-----------|---------|-------------|
-| `--quick` or `quick_mode: true` | 5 dimensions | Aspect ratio (unless `--aspect`) |
-| All 5 + `--aspect` specified | All | None |
+| `--quick` or `quick_mode: true` | 6 dimensions | Aspect ratio (unless `--aspect`) |
+| All 6 + `--aspect` specified | All | None |

+**Backup rule**: If `prompts/cover.md` exists, rename to `prompts/cover-backup-YYYYMMDD-HHMMSS.md`
+
 Save to `prompts/cover.md`. Full template: [references/workflow/prompt-template.md](references/workflow/prompt-template.md)

+**CRITICAL - References in YAML Frontmatter**:
+
+When reference files are saved to `refs/`, **MUST add `references` field in frontmatter**:
+
+```yaml
+---
+type: cover
+palette: warm
+rendering: flat-vector
+references:
+  - ref_id: 01
+    filename: refs/ref-01-podcast-thumbnail.jpg
+    usage: style
+---
+```
+
+| Rule | Action |
+|------|--------|
+| Files saved to `refs/` | Add to frontmatter `references` list |
+| Style extracted verbally (no file) | Omit `references` field, describe in body |
+| Before writing | Verify: `test -f refs/ref-NN-{slug}.{ext}` |
+
+**Reference Embedding**:

 ### Step 4: Generate Image

-1. Backup existing `cover.png` → `cover-backup-YYYYMMDD-HHMMSS.png` (if regenerating)
-2. Check available image generation skills; if multiple, ask user preference
-3. Call selected skill with prompt file path, output path (`cover.png`), aspect ratio
-4. On failure: auto-retry once before reporting error
+**4.1 Backup existing** `cover.png` → `cover-backup-YYYYMMDD-HHMMSS.png` (if regenerating)
+
+**4.2 Check available image generation skills**; if multiple, ask user preference
+
+**4.3 Process References** ⚠️ REQUIRED if references in frontmatter
+
+**Read `references` from prompt frontmatter** and process each entry:
+
+1. **Parse frontmatter** to get references list:
+   ```yaml
+   references:
+     - ref_id: 01
+       filename: refs/ref-01-podcast-thumbnail.jpg
+       usage: style
+   ```
+
+2. **VERIFY each file exists**:
+   ```bash
+   test -f refs/ref-NN-{slug}.{ext} && echo "exists" || echo "MISSING"
+   ```
+   - If file MISSING → ERROR, fix prompt or remove from references
+   - If file exists → proceed with processing
+
+3. Process based on `usage` type:
+
+| Usage | Action | Example |
+|-------|--------|---------|
+| `direct` | Add reference path to `--ref` parameter | `--ref refs/ref-01-brand.png` |
+| `style` | Analyze reference, append style traits to prompt | "Style: clean lines, gradient backgrounds..." |
+| `palette` | Extract colors from reference, append to prompt | "Colors: #E8756D coral, #7ECFC0 mint..." |
+
+3. Check image generation skill capability:
+
+| Skill Supports `--ref` | Action |
+|------------------------|--------|
+| Yes (e.g., baoyu-image-gen with Google) | Pass reference images via `--ref` |
+| No | Convert to text description, append to prompt |
+
+**Verification**: Before generating, confirm reference processing:
+```
+Reference Processing:
+- ref-01-brand.png: using as direct reference ✓
+- ref-02-style.png: extracted palette ✓
+```
+
+**4.4 Generate**
+
+1. Call selected skill with prompt file path, output path (`cover.png`), aspect ratio
+2. If references with `direct` usage AND skill supports `--ref`: include `--ref` parameter
+3. On failure: auto-retry once before reporting error

+## Reference Image Handling
+
+When user provides reference images (`--ref` or pasted images):
+
+### ⚠️ CRITICAL - Frontmatter References
+
+**MUST add `references` field in YAML frontmatter** when reference files are saved to `refs/`:
+
+```yaml
+---
+type: cover
+palette: warm
+rendering: flat-vector
+references:
+  - ref_id: 01
+    filename: refs/ref-01-podcast-thumbnail.jpg
+    usage: style
+---
+```
+
+| Field | Description |
+|-------|-------------|
+| `ref_id` | Sequential number (01, 02, ...) |
+| `filename` | Relative path from prompt file's parent directory |
+| `usage` | `direct` / `style` / `palette` |
+
+**Omit `references` field entirely** if no reference files saved (style extracted verbally only).
+
+### When to Include References in Frontmatter
+
+| Situation | Frontmatter Action | Generation Action |
+|-----------|-------------------|-------------------|
+| Reference file saved to `refs/` | Add to `references` list ✓ | Pass via `--ref` parameter |
+| Style extracted verbally (no file) | Omit `references` field | Describe in prompt body only |
+| File path in frontmatter but doesn't exist | ERROR - fix or remove | Generation will fail |
+
+**Before writing prompt with references, verify**: `test -f refs/ref-NN-{slug}.{ext}`
+
+### Reference Usage Types
+
+| Usage | When to Use | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Reference matches desired output closely | Pass to `--ref` parameter |
+| `style` | Extract visual style characteristics only | Describe style in prompt text |
+| `palette` | Extract color palette only | Include colors in prompt |
+
+### Step 1: Analyze References
+
+For each reference image, extract:
+- **Style**: Rendering technique, line quality, texture
+- **Composition**: Layout, visual hierarchy, focal points
+- **Color mood**: Palette characteristics (without specific colors)
+- **Elements**: Key visual elements and symbols used
+
+### Step 2: Embed in Prompt
+
+**If file saved AND skill supports `--ref`** (e.g., baoyu-image-gen with Google):
+- Pass ref images directly via `--ref` parameter
+- Add brief style note in prompt:
+
+```
+# Reference Style
+Follow the visual style of the attached reference image(s):
+- [1-2 sentence style summary from analysis]
+```
+
+**If file saved BUT skill does NOT support `--ref`**:
+- Embed detailed text description in prompt:
+
+```
+# Reference Style (Text Description)
+Emulate the following visual style from reference image(s):
+
+Reference 1: [filename]
+- Style: [detailed rendering technique description]
+- Composition: [layout and hierarchy description]
+- Elements: [key visual elements used]
+- Mood: [emotional tone and visual weight]
+
+[Repeat for additional references]
+
+Apply these style characteristics to the cover design while maintaining the specified Type, Palette, and Rendering dimensions.
+```
+
+**If style/palette extracted verbally (NO file saved)**:
+- DO NOT add references metadata to prompt
+- Append extracted info directly to prompt body:
+
+```
+# Extracted Style (from reference)
+
+COLORS (from reference):
+- Primary: #E8756D coral
+- Secondary: #7ECFC0 mint
+...
+
+STYLE (from reference):
+- Clean lines, minimal shadows
+- Gradient backgrounds
+- Flat vector icons
+...
+```
+
+### Reference Analysis Template
+
+Use this format when analyzing reference images:
+
+| Aspect | Analysis Points |
+|--------|-----------------|
+| **Rendering** | Line quality (clean/sketchy/painted), texture presence, depth treatment |
+| **Composition** | Element placement, whitespace ratio, visual flow |
+| **Typography** | Font style, text placement, hierarchy (if present) |
+| **Elements** | Icon vocabulary, decorative motifs, character style |
+| **Mood** | Contrast level, saturation, visual weight |

+# Study Notes Style
+
+Realistic handwritten photo aesthetic - student notes style, dense and messy but readable.
+
+## Element Combination
+
+```yaml
+canvas:
+  ratio: portrait-3-4
+  grid: single
+
+image_effects:
+  cutout: none
+  stroke: none
+  filter: natural-photo
+
+typography:
+  decorated: none
+  tags: none
+  direction: horizontal
+
+decorations:
+  emphasis: circle-mark | underline | checkmark | cross | star-simple
+  background: lined-paper-white
+  doodles: arrows-simple | margin-notes | corrections | explanatory-diagrams
+  frames: none
+```
+
+## Color Palette (Three-Color Annotation System)
+
+| Role | Colors | Hex |
+|------|--------|-----|
+| Primary | Blue ballpoint, Black ink | #1E3A5F, #1A1A1A |
+| Highlights | Yellow highlighter | #FFFF00 (50% opacity) |
+| Accents | Red pen (circles, underlines) | #CC0000 |
+| Background | White lined paper | #FFFFFF |
+
+## Visual Elements
+
+- Realistic photo perspective: top-down view of study desk
+- Hand holding blue ballpoint pen, actively underlining
+- Extremely dense handwritten content, filling entire page
+- Red pen annotations: circles, underlines, stars, boxes
+- Yellow highlighter marking key terms
+- Correction marks, cramped notes squeezed into margins
+- Simple hand-drawn symbols: → * ✓ ✗ !
+- Varying pen pressure creating lighter and darker strokes
+
+## Typography
+
+- Authentic student handwriting
+- Messy but readable, clear structure maintained
+- Varying font sizes (large titles, small body, tiny margin notes)
+- CJK optimized
+
+## Content Structure
+
+Three-section layout:
+
+### Top Section
+- Core topic (circled multiple times in red)
+- First section title + 3-4 key points
+- Arrow connections, red underlines
+
+### Middle Section
+- Second section title (red pen box)
+- Numbered steps ①②③
+- Specific methods and supplementary notes
+
+### Bottom Section
+- Third section title (red star)
+- Time points / key metrics
+- Key quotes / core tips (tiny corner notes)
+
+## Best Layout Pairings
+
+| Layout | Compatibility | Use Case |
+|--------|---------------|----------|
+| sparse | ✗ | Not suitable - style requires dense content |
+| balanced | ✓ | When content is lighter |
+| dense | ✓✓ | Best fit - knowledge notes, summaries |
+| list | ✓✓ | Step checklists, rankings |
+| comparison | ✓ | Comparative analysis |
+| flow | ✓ | Process flows |
+| mindmap | ✓✓ | Mind map notes |
+| quadrant | ✓ | Quadrant analysis |
+
+## Best For
+
+- Study guides, exam notes
+- Knowledge organization, framework summaries
+- Tutorial summaries, quick notes
+- "Top student notes" style content
+- Knowledge sharing requiring authentic feel
+
+## Style Rules
+
+### DO ✓
+- Keep content extremely dense
+- Use simple symbols (→ * ✓ ✗ !)
+- Annotate key points with red pen
+- Include correction marks
+- Squeeze tiny notes into margins
+
+### DON'T ✗
+- Use complex emojis
+- Leave too much whitespace
+- Make neat, tidy layouts
+- Add colorful decorations
+- Include cartoon elements
