+## 1.18.0 - 2026-01-23
+
+### Features
+- `baoyu-slide-deck`: introduces dimension-based style system—replaces monolithic style definitions with modular 4-dimension architecture: **Texture** (clean, grid, organic, pixel, paper), **Mood** (professional, warm, cool, vibrant, dark, neutral), **Typography** (geometric, humanist, handwritten, editorial, technical), and **Density** (minimal, balanced, dense). 16 presets map to specific dimension combinations, with "Custom dimensions" option for full flexibility.
+- `baoyu-slide-deck`: adds two-round confirmation workflow—Round 1 asks style/audience/slides/review preferences, Round 2 (optional) collects custom dimension choices when user selects "Custom dimensions".
+- `baoyu-slide-deck`: adds conditional outline and prompt review—users can skip reviews for faster generation or enable them for more control.
+
+### Documentation
+- `baoyu-slide-deck`: adds dimension reference files—`references/dimensions/texture.md`, `references/dimensions/mood.md`, `references/dimensions/typography.md`, `references/dimensions/density.md`, and `references/dimensions/presets.md` (preset → dimension mapping).
+- `baoyu-slide-deck`: adds design guidelines—`references/design-guidelines.md` with audience principles, visual hierarchy, content density, color selection, typography, and font recommendations.
+- `baoyu-slide-deck`: adds layout reference—`references/layouts.md` with layout options and selection tips.
+- `baoyu-slide-deck`: adds preferences schema—`references/config/preferences-schema.md` for EXTEND.md configuration.

+## 1.18.0 - 2026-01-23
+
+### 新功能
+- `baoyu-slide-deck`：引入基于维度的风格系统——将单一风格定义重构为模块化四维架构：**纹理** (clean 纯净、grid 网格、organic 有机、pixel 像素、paper 纸张)、**氛围** (professional 专业、warm 温暖、cool 冷静、vibrant 鲜艳、dark 暗色、neutral 中性)、**字体** (geometric 几何、humanist 人文、handwritten 手写、editorial 编辑、technical 技术)、**密度** (minimal 极简、balanced 均衡、dense 密集)。16 种预设映射到特定维度组合，并提供「自定义维度」选项实现完全灵活配置。
+- `baoyu-slide-deck`：新增两轮确认工作流——第一轮询问风格/受众/页数/审核偏好，第二轮（可选）在用户选择「自定义维度」时收集具体维度选择。
+- `baoyu-slide-deck`：新增条件性大纲和提示词审核——用户可跳过审核以加快生成，或启用审核以获得更多控制。
+
+### 文档
+- `baoyu-slide-deck`：新增维度参考文件——`references/dimensions/texture.md`、`references/dimensions/mood.md`、`references/dimensions/typography.md`、`references/dimensions/density.md`，以及 `references/dimensions/presets.md`（预设到维度的映射）。
+- `baoyu-slide-deck`：新增设计指南——`references/design-guidelines.md`，包含受众原则、视觉层次、内容密度、配色选择、字体排版和字体推荐。
+- `baoyu-slide-deck`：新增布局参考——`references/layouts.md`，包含布局选项和选择技巧。
+- `baoyu-slide-deck`：新增偏好配置模式——`references/config/preferences-schema.md`，用于 EXTEND.md 配置。

-**Match Layout to Content**:
-| Content Type | Recommended Layouts |
-|--------------|-------------------|
-| Single narrative | `bullet-list`, `image-caption` |
-| Two concepts | `split-screen`, `binary-comparison` |
-| Three items | `three-columns`, `icon-grid` |
-| Process/Steps | `linear-progression`, `winding-roadmap` |
-| Data/Metrics | `dashboard`, `key-stat` |
-| Relationships | `hub-spoke`, `venn-diagram` |
-| Hierarchy | `hierarchical-layers`, `tree-branching` |
-
-**Layout Flow Patterns**:
-| Position | Recommended Layouts |
-|----------|-------------------|
-| Opening | `title-hero`, `agenda` |
-| Middle | Content-specific layouts |
-| Closing | `quote-callout`, `key-stat` |
-
-**Common Mistakes to Avoid**:
-- ✗ Using 3-column layout for 2 items (leaves columns empty)
-- ✗ Stacking charts/tables below text (use side-by-side instead)
-- ✗ Image layouts without actual images
-- ✗ Quote layouts for emphasis (use only for real quotes with attribution)
-
 ## Design Philosophy
 
-This deck is designed for **reading and sharing**, not live presentation:
-- Each slide must be **self-explanatory** without verbal commentary
-- Structure content for **logical flow** when scrolling
-- Include **all necessary context** within each slide
-- Optimize for **social media sharing** and offline reading
+Decks designed for **reading and sharing**, not live presentation:
+- Each slide self-explanatory without verbal commentary
+- Logical flow when scrolling
+- All necessary context within each slide
+- Optimized for social media sharing
 
-### Visual Hierarchy Principles
+See `references/design-guidelines.md` for:
+- Audience-specific principles
+- Visual hierarchy
+- Content density guidelines
+- Color and typography selection
+- Font recommendations
 
-| 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
-
-Professional presentations balance information density with clarity.
-
-| Level | Description | Use When |
-|-------|-------------|----------|
-| High | Multiple data points, detailed charts, dense text | Expert audience, technical reviews, data-driven decisions |
-| Medium | Key points with supporting details, moderate visuals | 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
-- Information hierarchy guides the eye
-
-**Density by Slide Type**:
-| Slide Type | Recommended Density |
-|------------|-------------------|
-| Cover/Title | Low |
-| Agenda/Overview | Medium |
-| Content/Analysis | Medium-High |
-| Data/Metrics | High |
-| Quote/Impact | Low |
-| Summary/Takeaway | Medium |
-
-### Color Selection
-
-**Content-First Approach**:
-1. Analyze content topic, mood, and industry
-2. Consider target audience expectations
-3. Match palette to subject matter (not defaults)
-4. Ensure strong contrast for readability
-
-**Quick Palette Guide**:
-| Content Type | Recommended Palettes |
-|--------------|---------------------|
-| Technical/Architecture | Blues, grays, blueprint tones |
-| Educational/Friendly | Warm colors, earth tones |
-| Corporate/Professional | Navy, gold, structured palettes |
-| Creative/Artistic | Bold colors, unexpected combinations |
-| Scientific/Medical | Clean whites, precise color coding |
-
-**Note**: Full color specs in `references/styles/<style>.md`
-
-### Typography Principles
-
-| 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 |
-

 ## File Management
 
 ### Output Directory
 
-Each session creates an independent directory named by content slug:
-
 ```
 slide-deck/{topic-slug}/
-├── source-{slug}.{ext}    # Source files (text, images, etc.)
+├── source-{slug}.{ext}
 ├── outline.md
-├── outline-{style}.md     # Style variant outlines
 ├── prompts/
 │   └── 01-slide-cover.md, 02-slide-{slug}.md, ...
 ├── 01-slide-cover.png, 02-slide-{slug}.png, ...
@@ -378,119 +139,534 @@ slide-deck/{topic-slug}/
 └── {topic-slug}.pdf
 ```
 
-**Slug Generation**:
-1. Extract main topic from content (2-4 words, kebab-case)
-2. Example: "Introduction to Machine Learning" → `intro-machine-learning`
+**Slug**: Extract topic (2-4 words, kebab-case). Example: "Introduction to Machine Learning" → `intro-machine-learning`
 
-### Conflict Resolution
+**Conflict Handling**: See Step 1.3 for existing content detection and user options.
 
-If `slide-deck/{topic-slug}/` already exists:
-- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
-- Example: `intro-ml` exists → `intro-ml-20260118-143052`
+## Language Handling
 
-### Source Files
+**Detection Priority**:
+1. `--lang` flag (explicit)
+2. EXTEND.md `language` setting
+3. User's conversation language (input language)
+4. Source content language
 
-Copy all sources with naming `source-{slug}.{ext}`:
-- `source-article.md` (main text content)
-- `source-diagram.png` (image from conversation)
-- `source-data.xlsx` (additional file)
+**Rule**: ALL responses use user's preferred language:
+- Questions and confirmations
+- Progress reports
+- Error messages
+- Completion summaries
 
-Multiple sources supported: text, images, files from conversation.
+Technical terms (style names, file paths, code) remain in English.
 
 ## Workflow
 
-### Step 1: Analyze Content
+Copy this checklist and check off items as you complete them:
+
+```
+Slide Deck Progress:
+- [ ] Step 1: Setup & Analyze
+- [ ] Step 2: Confirmation ⚠️ REQUIRED (Round 1, optional Round 2)
+- [ ] Step 3: Generate outline
+- [ ] Step 4: Review outline (conditional)
+- [ ] Step 5: Generate prompts
+- [ ] Step 6: Review prompts (conditional)
+- [ ] Step 7: Generate images
+- [ ] Step 8: Merge to PPTX/PDF
+- [ ] Step 9: Output summary
+```
+
+### Flow
+
+```
+Input → Preferences → Analyze → [Check Existing?] → Confirm (1-2 rounds) → Outline → [Review Outline?] → Prompts → [Review Prompts?] → Images → Merge → Complete
+```
+
+### Step 1: Setup & Analyze
+
+**1.1 Load Preferences (EXTEND.md)**
+
+Use Bash to check EXTEND.md existence (priority order):
+
+```bash
+# Check project-level first
+test -f .baoyu-skills/baoyu-slide-deck/EXTEND.md && echo "project"
+
+# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
+test -f "$HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md" && echo "user"
+```
+
+┌──────────────────────────────────────────────────┬───────────────────┐
+│                       Path                       │     Location      │
+├──────────────────────────────────────────────────┼───────────────────┤
+│ .baoyu-skills/baoyu-slide-deck/EXTEND.md         │ Project directory │
+├──────────────────────────────────────────────────┼───────────────────┤
+│ $HOME/.baoyu-skills/baoyu-slide-deck/EXTEND.md   │ User home         │
+└──────────────────────────────────────────────────┴───────────────────┘
+
+**When EXTEND.md Found** → Read, parse, **output summary to user**:
+
+```
+📋 Loaded preferences from [full path]
+├─ Style: [preset/custom name]
+├─ Audience: [audience or "auto-detect"]
+├─ Language: [language or "auto-detect"]
+└─ Review: [enabled/disabled]
+```
+
+**When EXTEND.md Not Found** → First-time setup using AskUserQuestion or proceed with defaults.
+
+**EXTEND.md Supports**: Preferred style | Custom dimensions | Default audience | Language preference | Review preference
+
+Schema: `references/config/preferences-schema.md`
+
+**1.2 Analyze Content**
 
 1. Save source content (if pasted, save as `source.md`)
-2. Follow `references/analysis-framework.md` for deep content analysis
-3. Determine style (use `--style` or auto-select from signals)
-4. Detect languages (source vs. user preference)
-5. Plan slide count (`--slides` or dynamic)
+2. Follow `references/analysis-framework.md` for content analysis
+3. Analyze content signals for style recommendations
+4. Detect source language
+5. Determine recommended slide count
+6. Generate topic slug from content
 
-### Step 2: Generate Outline Variants
+**1.3 Check Existing Content**
 
-1. Generate 3 style variant outlines based on content analysis
-2. Follow `references/outline-template.md` for structure
-3. Save as `outline-{style}.md` for each variant
+Check if `slide-deck/{topic-slug}/` directory already exists.
 
-### Step 3: User Confirmation
+**If directory exists**, use AskUserQuestion:
 
-**Single AskUserQuestion with all applicable options:**
+```
+header: "Existing"
+question: "Existing content found. How to proceed?"
+options:
+  - label: "Regenerate outline"
+    description: "Keep images, regenerate outline only"
+  - label: "Regenerate images"
+    description: "Keep outline, regenerate images only"
+  - label: "Backup and regenerate"
+    description: "Backup to {slug}-backup-{timestamp}, then regenerate all"
+  - label: "Exit"
+    description: "Cancel, keep existing content unchanged"
+```
 
-| Question | When to Ask |
-|----------|-------------|
-| Style variant | Always (3 options + custom) |
-| Language | Only if source ≠ user language |
+**Save to `analysis.md`** with:
+- Topic, audience, content signals
+- Recommended style (based on Auto Style Selection)
+- Recommended slide count
+- Language detection
 
-After selection:
-- Copy selected `outline-{style}.md` to `outline.md`
-- Regenerate in different language if requested
-- User may edit `outline.md` for fine-tuning
+### Step 2: Confirmation ⚠️ REQUIRED
 
-If `--outline-only`, stop here.
+**Two-round confirmation**: Round 1 always, Round 2 only if "Custom dimensions" selected.
 
-### Step 4: Generate Prompts
+**Language**: Use user's input language or saved language preference.
+
+**Display summary**:
+- Content type + topic identified
+- Language: [from EXTEND.md or detected]
+- **Recommended style**: [preset] (based on content signals)

+## Partial Workflows
+
+| Option | Workflow |
+|--------|----------|
+| `--outline-only` | Steps 1-3 only (stop after outline) |
+| `--prompts-only` | Steps 1-5 (generate prompts, skip images) |
+| `--images-only` | Skip to Step 7 (requires existing prompts/) |
+| `--regenerate N` | Regenerate specific slide(s) only |
+
+### Using `--prompts-only`
+
+Generate outline and prompts without images:
+
+```bash
+/baoyu-slide-deck content.md --prompts-only
+```
+
+Output: `outline.md` + `prompts/*.md` ready for review/editing.
+
+### Using `--images-only`
+
+Generate images from existing prompts (starts at Step 7):
+
+```bash
+/baoyu-slide-deck slide-deck/topic-slug/ --images-only
+```
+
+Prerequisites:
+- `prompts/` directory with slide prompt files
+- `outline.md` with style information
+
+### Using `--regenerate`
+
+Regenerate specific slides:
+
+```bash
+# Single slide
+/baoyu-slide-deck slide-deck/topic-slug/ --regenerate 3
+
+# Multiple slides
+/baoyu-slide-deck slide-deck/topic-slug/ --regenerate 2,5,8
+```
+
+Flow:
+1. Read existing prompts for specified slides
+2. Regenerate images only for those slides
+3. Regenerate PPTX/PDF
+

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

+## Building STYLE_INSTRUCTIONS from Dimensions
+
+When using custom dimensions or presets, build STYLE_INSTRUCTIONS by combining:
+
+### 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
