+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Claude Code marketplace plugin providing AI-powered content generation skills. Skills use Gemini Web API (reverse-engineered) for text/image generation and Chrome CDP for browser automation.
+
+## Architecture
+
+```
+skills/
+├── baoyu-gemini-web/          # Core: Gemini API wrapper (text + image gen)
+├── baoyu-xhs-images/          # Xiaohongshu infographic series (1-10 images)
+├── baoyu-cover-image/         # Article cover images (2.35:1 aspect)
+├── baoyu-slide-deck/          # Presentation slides with outlines
+├── baoyu-article-illustrator/ # Smart illustration placement
+├── baoyu-post-to-x/           # X/Twitter posting automation
+└── baoyu-post-to-wechat/      # WeChat Official Account posting
+```
+
+Each skill contains:
+- `SKILL.md` - YAML front matter (name, description) + documentation
+- `scripts/` - TypeScript implementations
+- `prompts/system.md` - AI generation guidelines (optional)
+
+## Running Skills
+
+All scripts run via Bun (no build step):
+
+```bash
+npx -y bun skills/<skill>/scripts/main.ts [options]
+```
+
+Examples:
+```bash
+# Text generation
+npx -y bun skills/baoyu-gemini-web/scripts/main.ts "Hello"
+
+# Image generation
+npx -y bun skills/baoyu-gemini-web/scripts/main.ts --prompt "A cat" --image cat.png
+
+# From prompt files
+npx -y bun skills/baoyu-gemini-web/scripts/main.ts --promptfiles system.md content.md --image out.png
+```
+
+## Key Dependencies
+
+- **Bun**: TypeScript runtime (via `npx -y bun`)
+- **Chrome**: Required for `baoyu-gemini-web` auth and `baoyu-post-to-x` automation
+- **No npm packages**: Self-contained TypeScript, no external dependencies
+
+## Authentication
+
+`baoyu-gemini-web` uses browser cookies for Google auth:
+- First run opens Chrome for login
+- Cookies cached in data directory
+- Force refresh: `--login` flag
+
+## Plugin Configuration
+
+`.claude-plugin/marketplace.json` defines plugin metadata and skill paths. Version follows semver.
+
+## Adding New Skills
+
+**IMPORTANT**: All skills MUST use `baoyu-` prefix to avoid conflicts when users import this plugin.
+
+1. Create `skills/baoyu-<name>/SKILL.md` with YAML front matter
+   - Directory name: `baoyu-<name>`
+   - SKILL.md `name` field: `baoyu-<name>`
+2. Add TypeScript in `skills/baoyu-<name>/scripts/`
+3. Add prompt templates in `skills/baoyu-<name>/prompts/` if needed
+4. Register in `marketplace.json` plugins[0].skills array as `./skills/baoyu-<name>`
+5. **Add Script Directory section** to SKILL.md (see template below)
+
+### Script Directory Template
+
+Every SKILL.md with scripts MUST include this section after Usage:
+
+```markdown
+## Script Directory
+
+**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
+
+**Agent Execution Instructions**:
+1. Determine this SKILL.md file's directory path as `SKILL_DIR`
+2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
+3. Replace all `${SKILL_DIR}` in this document with the actual path
+
+**Script Reference**:
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | Main entry point |
+| `scripts/other.ts` | Other functionality |
+```
+
+When referencing scripts in workflow sections, use `${SKILL_DIR}/scripts/<name>.ts` so agents can resolve the correct path.
+
+## Code Style
+
+- TypeScript throughout, no comments
+- Async/await patterns
+- Short variable names
+- Type-safe interfaces

+    └── ...
+```
+
+## Workflow
+
+### Step 1: Analyze Content & Select Style
+
+1. Read article content
+2. If `--style` specified, use that style
+3. Otherwise, scan for style signals and auto-select
+4. Extract key information:
+   - Main topic and themes
+   - Core messages per section
+   - Abstract concepts needing visualization
+
+### Step 2: Identify Illustration Positions
+
+**Three Purposes of Illustrations**:
+1. **Information Supplement**: Help understand abstract concepts
+2. **Concept Visualization**: Transform abstract ideas into concrete visuals
+3. **Imagination Guidance**: Create atmosphere, enhance reading experience
+
+**Content Suitable for Illustrations**:
+- Abstract concepts needing visualization
+- Processes/steps needing diagrams
+- Comparisons needing visual representation
+- Core arguments needing reinforcement
+- Scenarios needing imagination guidance
+
+**Illustration Count**:
+- Consider at least 1 image per major section
+- Prioritize core arguments and abstract concepts
+- **Principle: More is better than fewer**
+
+### Step 3: Generate Illustration Plan
+
+```markdown
+# Illustration Plan
+
+**Article**: [article path]
+**Style**: [selected style]
+**Illustration Count**: N images
+
+---
+
+## Illustration 1
+
+**Insert Position**: [section name] / [paragraph description]
+**Purpose**: [why illustration needed here]
+**Visual Content**: [what the image should show]
+**Filename**: illustration-[slug].png
+
+---
+
+## Illustration 2
+...
+```
+
+### Step 4: Create Prompt Files
+
+Save prompts to `prompts/` directory with style-specific details.
+
+**Prompt Format**:
+
+```markdown
+Illustration theme: [concept in 2-3 words]
+Style: [style name]
+
+Visual composition:
+- Main visual: [description matching style]
+- Layout: [element positioning]
+- Decorative elements: [style-appropriate decorations]
+
+Color scheme:
+- Primary: [style primary color]
+- Background: [style background color]
+- Accent: [style accent color]
+
+Text content (if any):
+- [Any labels or captions in content language]
+
+Style notes: [specific style characteristics]
+```
+
+### Step 5: Generate Images
+
+**Image Generation Skill Selection**:
+1. Check available image generation skills
+2. If multiple skills available, ask user to choose
+
+**Generation Flow**:
+1. Call selected image generation skill with prompt file and output path
+2. Generate images sequentially
+3. After each image, output progress: "Generated X/N"
+4. On failure, auto-retry once
+5. If retry fails, log reason, continue to next
+
+### Step 6: Update Article
+
+Insert generated images at corresponding positions:
+
+```markdown
+![illustration description](imgs/illustration-[slug].png)
+```
+
+**Insertion Rules**:
+- Insert image after corresponding paragraph
+- Leave one blank line before and after image
+- Alt text uses concise description in article's language
+
+### Step 7: Output Summary
+
+```
+Article Illustration Complete!
+
+Article: [article path]
+Style: [style name]
+Generated: X/N images successful
+
+Illustration Positions:
+- illustration-xxx.png → After section "Section Name"
+- illustration-yyy.png → After section "Another Section"

+
+**Target directory**:
+- With source path: `[source-dir]/comic/`
+- Without source: `comic-outputs/YYYY-MM-DD/[topic-slug]/`
+
+## Workflow
+
+### Step 1: Analyze Content
+
+1. Read source content
+2. Select style (from `--style` or auto-detect)
+3. Select layout (from `--layout` or auto-detect per page)
+4. Determine page count:
+   - Short story: 5-8 pages
+   - Medium complexity: 9-15 pages
+   - Full biography: 16-25 pages
+
+### Step 2: Define Characters
+
+**Purpose**: Establish visual consistency across all pages.
+
+1. Extract all characters from content (protagonist, supporting, antagonist, narrator)
+2. Create `characters/characters.md` with visual specs for each character
+3. Generate `characters/characters.png` (character reference sheet)
+
+**Reference**: `references/character-template.md` for detailed format and examples.
+
+### Step 3: Generate Outline
+
+Create `outline.md` with:
+- Metadata (title, style, layout, page count, character reference path)
+- Cover design
+- Each page: layout, panel breakdown, visual prompts
+
+**Reference**: `references/outline-template.md` for detailed format.
+
+### Step 4: Generate Images
+
+For each page (cover + pages):
+
+1. Save prompt to `prompts/XX-page.md`
+2. Call image generation skill with:
+   - Base prompt: `references/base-prompt.md`
+   - Character reference (text or image, depending on skill capability)
+   - Page prompt
+   - Output path
+
+**Image Generation Skill Selection**:
+- Check available image generation skills in the environment
+- If multiple skills available, ask user preference
+
+**Character Reference Handling**:
+- If skill supports reference image: pass `characters/characters.png` as reference image
+- If skill does NOT support reference image: include `characters/characters.md` content in the prompt
+- This ensures character visual consistency across all pages
+
+**Session Management**:
+If the image generation skill supports `--sessionId`:
+1. Generate a unique session ID at the start (e.g., `comic-{topic-slug}-{timestamp}`)
+2. Use the same session ID for character sheet and all pages
+3. This ensures visual consistency (character appearance, style) across all generated images
+
+3. Report progress after each generation
+
+### Step 5: Merge to PDF
+
+After all images are generated, merge them into a PDF file:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/merge-to-pdf.ts <comic-dir>
+```
+
+This creates `{topic-slug}.pdf` in the comic directory with all pages as full-page images.
+
+### Step 6: Completion Report
+
+```

+## Style-Specific Guidelines
+
+### Ohmsha Style (`--style ohmsha`)
+
+Additional requirements for educational manga:
+- Default characters: Student (大雄), Mentor (哆啦A梦), Antagonist (胖虎)
+- Custom: `--characters "Student:小明,Mentor:教授"`
+- Must use visual metaphors (gadgets, action scenes) - NO talking heads
+- Page titles: narrative style, not "Page X: Topic"

+| Concept | Visual Metaphor |
+|---------|----------------|
+| Neural networks | Glowing nodes connected by clean lines |
+| Data flow | Luminous particles along simple paths |
+| Algorithms | Geometric patterns, building blocks |
+| Logic/proof | Interlocking puzzle pieces |
+| Discovery | Light breaking through darkness |
+| Uncertainty | Forking paths, question marks |
+| Time | Clock motifs, calendar pages |

+When depicting narrator characters addressing the reader:
+- Character may look directly out of panel
+- Can appear in "present day" framing scenes
+- Distinct visual treatment from main timeline
+- Often at page edges or in dedicated panels
+- May comment on or question the events shown
+
+## Historical Accuracy
+
+- Research period-specific details: costumes, technology, architecture
+- Show aging naturally for characters across time periods
+- Iconic items and locations rendered recognizably
+- Balance accuracy with stylization
+
+## Language
+
+- All text in Chinese (中文) unless source material is in another language
+- Use Chinese full-width punctuation: ""，。！

+
+## Handling Age Variants
+
+For biographies spanning many years, define age variants:
+
+```markdown
+## Alan Turing - Age Variants
+
+### Young (1920s, age 10-18)
+- Boyish features, round face
+- School uniform (Sherborne)
+- Curious, eager expression
+
+### Adult (1930s-40s, age 25-35)
+- Angular face, defined jaw
+- Tweed jacket, rumpled appearance
+- Intense, focused expression
+
+### Later (1950s, age 40+)
+- Slightly weathered
+- More casual dress
+- Thoughtful, sometimes melancholic
+```
+
+## Best Practices
+
+| Practice | Description |
+|----------|-------------|
+| Be specific | "Short dark wavy hair, parted left" not just "dark hair" |
+| Use distinguishing features | Glasses, scars, accessories that identify character |
+| Define color codes | Use specific color names or hex codes |
+| Include age markers | Wrinkles, posture, clothing style matching era |
+| Reference real people | For historical figures, note "based on 1940s photographs" |
+
+## Why Character Reference Matters
+
+Without unified character definition, AI generates inconsistent appearances. The reference sheet provides:
+1. Visual anchors for consistent features
+2. Color palettes for consistent coloring
+3. Expression documentation for emotional portrayals

+# Ohmsha Manga Guide Style
+
+Guidelines for `--style ohmsha` educational manga comics.
+
+## Character Setup
+
+| Role | Default | Traits |
+|------|---------|--------|
+| Student (Role A) | 大雄 | Confused, asks basic but crucial questions, represents reader |
+| Mentor (Role B) | 哆啦A梦 | Knowledgeable, patient, uses gadgets as technical metaphors |
+| Antagonist (Role C, optional) | 胖虎 | Represents misunderstanding, or "noise" in the data |
+
+Custom characters: `--characters "Student:小明,Mentor:教授,Antagonist:Bug怪"`
+
+## Character Reference Sheet Style
+
+For Ohmsha style, use manga/anime style with:
+- Exaggerated expressions for educational clarity
+- Simple, distinctive silhouettes
+- Bright, saturated color palettes
+- Chibi/SD (super-deformed) variants for comedic reactions
+
+## Outline Spec Block
+
+Every ohmsha outline must start with:
+
+```markdown
+【漫画规格单】
+- Language: [Same as input content]
+- Style: Ohmsha (Manga Guide), Full Color
+- Layout: Vertical Scrolling Comic (竖版条漫)
+- Characters: [List character names and roles]
+- Character Reference: characters/characters.png
+- Page Limit: ≤20 pages
+```
+
+## Visual Metaphor Rules (Critical)
+
+**NEVER** create "talking heads" panels. Every technical concept must become:
+
+1. **A tangible gadget/prop** - Something characters can hold, use, demonstrate
+2. **An action scene** - Characters doing something that illustrates the concept
+3. **A visual environment** - Stepping into a metaphorical space
+
+### Examples
+
+| Concept | Bad (Talking Heads) | Good (Visual Metaphor) |
+|---------|---------------------|------------------------|
+| Word embeddings | Characters discussing vectors | 哆啦A梦拿出"词向量压缩机"，把书本压缩成彩色小球 |
+| Gradient descent | Explaining math formula | 大雄在山谷地形上滚球，寻找最低点 |
+| Neural network | Diagram on whiteboard | 角色走进由发光节点组成的网络迷宫 |
+
+## Page Title Convention
+
+Avoid AI-style "Title: Subtitle" format. Use narrative descriptions:
+
+- ❌ "Page 3: Introduction to Neural Networks"
+- ✓ "Page 3: 大雄被海量单词淹没，哆啦A梦拿出'词向量压缩机'"
+
+## Ending Requirements
+
+- NO generic endings ("What will you choose?", "Thanks for reading")
+- End with: Technical summary moment OR character achieving a small goal
+- Final panel: Sense of accomplishment, not open-ended question
+
+### Good Endings
+
+- Student successfully applies learned concept
+- Visual callback to opening problem, now solved
+- Mentor gives summary while student demonstrates understanding
+
+### Bad Endings
+
+- "What do you think?" open questions
+- "Thanks for reading this tutorial"
+- Cliffhanger without resolution
+
+## Layout Preference
+
+Ohmsha style typically uses:
+- `webtoon` (vertical scrolling) - Primary choice
+- `dense` - For information-heavy sections
+- `mixed` - For varied pacing
+
+Avoid `cinematic` and `splash` for educational content.

+| Algorithm iteration | Ascending spiral staircase |
+| Breakthrough moment | Shattering barrier, piercing light |
+| Logical proof | Building blocks assembling |
+| Uncertainty | Forking paths, fog, multiple shadows |
+
+## Text Element Design
+
+| Text Type | Style | Usage |
+|-----------|-------|-------|
+| Character dialogue | Oval speech bubble | Main narrative speech |
+| Narrator commentary | Rectangular box | Explanation, commentary |
+| Caption bar | Edge-mounted rectangle | Time, location info |
+| Thought bubble | Cloud shape | Character inner monologue |
+| Term label | Bold / special color | First appearance of technical terms |
+
+## Prompt Structure for Consistency
+
+Each page prompt should include character reference:
+
+```
+[CHARACTER REFERENCE]
+(Key details from characters.md for characters in this page)
+
+[PAGE CONTENT]
+(Specific scene, panel layout, and visual elements)
+
+[CONSISTENCY REMINDER]

+# ohmsha
+
+Ohmsha Manga Guide style - educational manga with visual metaphors
+
+## Core Philosophy
+
+Educational manga where every concept becomes a visual metaphor or action. NO talking heads - characters must DO things, not just explain.
+
+## Visual Style
+
+- **Type**: Manga-style educational comic
+- **Orientation**: Portrait (vertical), optimized for scrolling
+- **Colors**: Full color, bright and clean anime/manga aesthetic
+- **Lines**: Clean manga lines (1.5-2px), smooth curves, expressive
+
+## Character Design (Manga Style)
+
+- Anime/manga proportions: slightly larger eyes, expressive faces
+- **Student character**: Confused expressions, question marks (？), sweat drops, represents reader
+- **Mentor character**: Confident poses, explanatory gestures, produces gadgets/tools
+- Clear emotional indicators using manga conventions (！, ？, sweat drops, sparkles)
+- Consistent character designs across all panels
+
+## Background Treatment
+
+- Simplified backgrounds during dialogue/explanation
+- Detailed "imagination spaces" for concept visualization
+- Technical diagrams styled as holographic displays or magical blueprints
+- Screen tone effects for atmosphere
+
+## Visual Metaphor Requirements (CRITICAL)
+
+Every technical concept MUST be visualized as:
+
+| Concept Type | Visualization Approach |
+|-------------|----------------------|
+| Algorithm | Gadget/machine that demonstrates the process |
+| Data structure | Physical space characters can enter/explore |
+| Mathematical formula | Transformation visible in environment |
+| Abstract process | Tangible flow of particles/objects |
+
+**Wrong approach**: Character points at blackboard explaining
+**Right approach**: Character uses "Concept Visualizer" gadget, steps into metaphorical space
+
+### Visual Metaphor Examples
+
+| Concept | Wrong (Talking Head) | Right (Visual Metaphor) |
+|---------|---------------------|------------------------|
+| Attention mechanism | Character points at formula on blackboard | "Attention Flashlight" gadget illuminates key words in dark room |
+| Gradient descent | "The algorithm minimizes loss" | Character rides ball rolling down mountain valley |
+| Neural network | Diagram with arrows | Living network of glowing creatures passing messages |
+| Overfitting | "The model memorized the data" | Character wearing clothes that fit only one specific pose |
+
+## Panel Layout for Ohmsha
+
+- Vertical scroll optimized (webtoon style)
+- Single column, panels stack vertically
+- Generous whitespace between major beats
+- Panels can bleed to edges for impact
+- "Float" elements between panels for emphasis
+
+## Special Visual Elements
+
+- **Gadget reveals**: Dramatic unveiling with sparkle effects
+- **Concept spaces**: Rounded borders, glowing edges for "imagination mode"
+- **Information displays**: Holographic UI style for technical details
+- **Aha moments**: Radial lines, light burst effects
+- **Confusion**: Spiral eyes, question marks floating above head
+
+## Text Elements (Ohmsha)
+
+- Hand-lettered manga style
+- Sound effects integrated visually (ドキドキ, ピカーン, etc.)
+- Speech bubbles: rounded for normal, spiky for excitement/shock
+- Thought bubbles for internal process visualization
+- Technical terms in bold with furigana-style annotations if needed
+
+## Color Palette
+
+- Primary: Bright blue (#4299E1), warm orange (#ED8936), soft green (#68D391)
+- Skin: Anime-style warm (#FEEBC8)
+- Background: Clean white, soft gradients
+- Gadgets: Metallic accents (#FFD700, #C0C0C0), vibrant highlights
+- Concept spaces: Pastel backgrounds, glowing accents
+
+## Quality Markers (Ohmsha)
+
+- ✓ Every concept is a visual metaphor, not just explained
+- ✓ Characters are DOING things, not just talking
+- ✓ Clear student/mentor dynamic
+- ✓ Gadgets and props drive the explanation
+- ✓ Expressive manga-style emotions
+- ✓ Information density through visual design, not text walls
+
+## Character Setup (Required)
+
+Define characters before generating:
+
+| Role | Default | Traits |
+|------|---------|--------|
+| Student (Role A) | 大雄 | Confused, asks basic but crucial questions, represents reader |
+| Mentor (Role B) | 哆啦A梦 | Knowledgeable, patient, uses gadgets as technical metaphors |
+| Antagonist (Role C, optional) | 胖虎 | Represents misunderstanding, or "noise" in the data |

+
+## Workflow
+
+### Step 1: Analyze Content
+
+Extract key information:
+- **Main topic**: What is the article about?
+- **Core message**: What's the key takeaway?
+- **Tone**: Serious, playful, inspiring, educational?
+- **Keywords**: Identify style-signaling words
+
+### Step 2: Select Style
+
+If `--style` specified, use that style. Otherwise:
+1. Scan content for style signals (see Auto Style Selection table)
+2. Match signals to most appropriate style
+3. Default to `elegant` if no clear signals
+
+### Step 3: Generate Cover Concept
+
+Create a cover image concept based on selected style:
+
+**Title** (if included, max 8 characters):
+- Distill the core message into a punchy headline
+- Use hooks: numbers, questions, contrasts, pain points
+- Skip if `--no-title` flag is used
+
+**Visual Elements**:
+- Style-appropriate imagery and icons
+- 1-2 symbolic elements representing the topic
+- Metaphors or analogies that fit the style
+
+### Step 4: Create Prompt File
+
+**Prompt Format**:
+
+```markdown
+Cover theme: [topic in 2-3 words]
+Style: [selected style name]
+
+[If title included:]
+Title text: [8 characters or less, in content language]
+Subtitle: [optional, in content language]
+
+Visual composition:
+- Main visual: [description matching style]
+- Layout: [positioning based on title inclusion]
+- Decorative elements: [style-appropriate elements]
+
+Color scheme:
+- Primary: [style primary color]
+- Background: [style background color]
+- Accent: [style accent color]
+
+Style notes: [specific style characteristics to emphasize]
+
+[If no title:]
+Note: No title text, pure visual illustration only.
+```
+
+### Step 5: Generate Image
+
+**Image Generation Skill Selection**:
+1. Check available image generation skills
+2. If multiple skills available, ask user to choose
+
+**Generation**:
+Call selected image generation skill with prompt file and output path.
+
+### Step 6: Output Summary
+
+```
+Cover Image Generated!
+
+Topic: [topic]
+Style: [style name]
+Title: [cover title] (or "No title - visual only")
+Location: [output path]
+
+Preview the image to verify it matches your expectations.
+```
+
+## Notes
+
+- Cover should be instantly understandable at small preview sizes
+- Title (if included) must be readable and impactful
+- Visual metaphors work better than literal representations
+- Maintain style consistency throughout the cover
+- Image generation typically takes 10-30 seconds
+- Title text language should match content language

+
+## Text Style (When Title Included)
+
+- **ALL text MUST be hand-drawn style**
+- Title text: Large, eye-catching, max 8 characters
+- May include 1 line of subtitle or keyword tags
+- Font style harmonizes with illustration style
+- **DO NOT use realistic or computer-generated fonts**
+
+## Language
+
+- Use the same language as the content provided below for any text elements
+- Match punctuation style to the content language
+
+---
+
+Please use nano banana pro to generate the cover image based on the content provided below:

+name: baoyu-gemini-web
+description: Image generation skill using Gemini Web. Generates images from text prompts via Google Gemini. Also supports text generation. Use as the image generation backend for other skills like cover-image, xhs-images, article-illustrator.
+---
+
+# Gemini Web Client
+
+Supports:
+- Text generation
+- Image generation (download + save)
+- Reference image upload (attach images for vision tasks)
+- Multi-turn conversations within the same executor instance (`keepSession`)
+- Experimental video generation (`generateVideo`) — Gemini may return an async placeholder; download might require Gemini web UI
+
+## Script Directory
+
+**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
+
+**Agent Execution Instructions**:
+1. Determine this SKILL.md file's directory path as `SKILL_DIR`
+2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
+3. Replace all `${SKILL_DIR}` in this document with the actual path
+
+**Script Reference**:
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | CLI entry point for text/image generation |
+| `scripts/executor.ts` | Programmatic Gemini executor API |
+
+## Quick start
+
+```bash
+npx -y bun scripts/main.ts "Hello, Gemini"
+npx -y bun scripts/main.ts --prompt "Explain quantum computing"
+npx -y bun scripts/main.ts --prompt "A cute cat" --image cat.png
+npx -y bun scripts/main.ts --promptfiles system.md content.md --image out.png
+
+# Multi-turn conversation (agent generates unique sessionId)
+npx -y bun scripts/main.ts "Remember this: 42" --sessionId my-unique-id-123
+npx -y bun scripts/main.ts "What number?" --sessionId my-unique-id-123
+```
+
+## Executor options (programmatic)
+
+This skill is typically consumed via `createGeminiWebExecutor(geminiOptions)` (see `scripts/executor.ts`).
+
+Key options in `GeminiWebOptions`:
+- `referenceImages?: string | string[]` Upload local images as references (vision input).
+- `keepSession?: boolean` Reuse Gemini `chatMetadata` to continue the same conversation across calls (required if you want reference images to persist across multiple messages).
+- `generateVideo?: string` Generate a video and (best-effort) download to the given path. Gemini may return `video_gen_chip` (async); in that case you must open Gemini web UI to download the result.
+
+Notes:
+- `generateVideo` cannot be combined with `generateImage` / `editImage`.
+- When `keepSession=true` and `referenceImages` is set, reference images are uploaded once per executor instance.
+
+## Commands
+
+### Text generation
+
+```bash
+# Simple prompt (positional)
+npx -y bun scripts/main.ts "Your prompt here"
+
+# Explicit prompt flag
+npx -y bun scripts/main.ts --prompt "Your prompt here"
+npx -y bun scripts/main.ts -p "Your prompt here"
+
+# With model selection
+npx -y bun scripts/main.ts -p "Hello" -m gemini-2.5-pro
+
+# Pipe from stdin
+echo "Summarize this" | npx -y bun scripts/main.ts
+```
+
+### Image generation
+
+```bash
+# Generate image with default path (./generated.png)
+npx -y bun scripts/main.ts --prompt "A sunset over mountains" --image
+
+# Generate image with custom path
+npx -y bun scripts/main.ts --prompt "A cute robot" --image robot.png
+
+# Shorthand
+npx -y bun scripts/main.ts "A dragon" --image=dragon.png
+```
+
+### Output formats
+
+```bash
+# Plain text (default)
+npx -y bun scripts/main.ts "Hello"
+
+# JSON output
+npx -y bun scripts/main.ts "Hello" --json
+```
+
+## Options
+
+| Option | Description |
+|--------|-------------|
+| `--prompt <text>`, `-p` | Prompt text |
+| `--promptfiles <files...>` | Read prompt from files (concatenated in order) |
+| `--model <id>`, `-m` | Model: gemini-3-pro (default), gemini-2.5-pro, gemini-2.5-flash |
+| `--image [path]` | Generate image, save to path (default: generated.png) |
+| `--sessionId <id>` | Session ID for multi-turn conversation (agent generates unique ID) |
+| `--list-sessions` | List saved sessions (max 100, sorted by update time) |
+| `--json` | Output as JSON |
+| `--login` | Refresh cookies only, then exit |
+| `--cookie-path <path>` | Custom cookie file path |
+| `--profile-dir <path>` | Chrome profile directory |
+| `--help`, `-h` | Show help |
+
+CLI note: `scripts/main.ts` supports text generation, image generation, and multi-turn conversations via `--sessionId`. Reference images and video generation are exposed via the executor API.
+
+## Models
+
+- `gemini-3-pro` - Default, latest model
+- `gemini-2.5-pro` - Previous generation pro
+- `gemini-2.5-flash` - Fast, lightweight
+
+## Authentication
+
+First run opens Chrome to authenticate with Google. Cookies are cached for subsequent runs.
+
+```bash
+# Force cookie refresh
+npx -y bun scripts/main.ts --login
+```
+
+## Environment variables
+
+| Variable | Description |
+|----------|-------------|
+| `GEMINI_WEB_DATA_DIR` | Data directory |
+| `GEMINI_WEB_COOKIE_PATH` | Cookie file path |
+| `GEMINI_WEB_CHROME_PROFILE_DIR` | Chrome profile directory |
+| `GEMINI_WEB_CHROME_PATH` | Chrome executable path |
+
+## Examples
+
+### Generate text response
+```bash
+npx -y bun scripts/main.ts "What is the capital of France?"
+```
+
+### Generate image
+```bash
+npx -y bun scripts/main.ts "A photorealistic image of a golden retriever puppy" --image puppy.png
+```
+
+### Get JSON output for parsing
+```bash
+npx -y bun scripts/main.ts "Hello" --json | jq '.text'
+```
+
+### Generate image from prompt files
+```bash
+# Concatenate system.md + content.md as prompt
+npx -y bun scripts/main.ts --promptfiles system.md content.md --image output.png
+```
+
+### Multi-turn conversation
+```bash
+# Start a session with unique ID (agent generates this)
+npx -y bun scripts/main.ts "You are a helpful math tutor." --sessionId task-abc123
+
+# Continue the conversation (remembers context)
+npx -y bun scripts/main.ts "What is 2+2?" --sessionId task-abc123
+npx -y bun scripts/main.ts "Now multiply that by 10" --sessionId task-abc123
+
+# List recent sessions (max 100, sorted by update time)
+npx -y bun scripts/main.ts --list-sessions
+```
+
+Session files are stored in `~/Library/Application Support/baoyu-skills/gemini-web/sessions/<id>.json` and contain:
+- `id`: Session ID
+- `metadata`: Gemini chat metadata for continuation
+- `messages`: Array of `{role, content, timestamp, error?}`
+- `createdAt`, `updatedAt`: Timestamps

+# X Articles - Detailed Guide
+
+Publish Markdown articles to X Articles editor with rich text formatting and images.
+
+## Prerequisites
+
+- X Premium subscription (required for Articles)
+- Google Chrome installed
+- `bun` installed
+
+## Usage
+
+```bash
+# Publish markdown article (preview mode)
+npx -y bun ${SKILL_DIR}/scripts/x-article.ts article.md
+
+# With custom cover image
+npx -y bun ${SKILL_DIR}/scripts/x-article.ts article.md --cover ./cover.jpg
+
+# Actually publish
+npx -y bun ${SKILL_DIR}/scripts/x-article.ts article.md --submit
+```
+
+## Markdown Format
+
+```markdown
+---
+title: My Article Title
+cover_image: /path/to/cover.jpg
+---
+
+# Title (becomes article title)
+
+Regular paragraph text with **bold** and *italic*.
+
+## Section Header
+
+More content here.
+
+![Image alt text](./image.png)
+
+- List item 1
+- List item 2
+
+1. Numbered item
+2. Another item
+
+> Blockquote text
+
+[Link text](https://example.com)
+
+\`\`\`
+Code blocks become blockquotes (X doesn't support code)
+\`\`\`
+```
+
+## Frontmatter Fields
+
+| Field | Description |
+|-------|-------------|
+| `title` | Article title (or uses first H1) |
+| `cover_image` | Cover image path or URL |
+| `cover` | Alias for cover_image |
+| `image` | Alias for cover_image |
+
+## Image Handling
+
+1. **Cover Image**: First image or `cover_image` from frontmatter
+2. **Remote Images**: Automatically downloaded to temp directory
+3. **Placeholders**: Images in content use `[[IMAGE_PLACEHOLDER_N]]` format
+4. **Insertion**: Placeholders are found, selected, and replaced with actual images
+
+## Markdown to HTML Script
+
+Convert markdown and inspect structure:
+
+```bash
+# Get JSON with all metadata
+npx -y bun ${SKILL_DIR}/scripts/md-to-html.ts article.md
+
+# Output HTML only
+npx -y bun ${SKILL_DIR}/scripts/md-to-html.ts article.md --html-only
+
+# Save HTML to file
+npx -y bun ${SKILL_DIR}/scripts/md-to-html.ts article.md --save-html /tmp/article.html
+```
+
+JSON output:
+```json
+{
+  "title": "Article Title",
+  "coverImage": "/path/to/cover.jpg",
+  "contentImages": [
+    {
+      "placeholder": "[[IMAGE_PLACEHOLDER_1]]",
+      "localPath": "/tmp/x-article-images/img.png",
+      "blockIndex": 5
+    }
+  ],
+  "html": "<p>Content...</p>",
+  "totalBlocks": 20
+}
+```
+
+## Supported Formatting
+
+| Markdown | HTML Output |
+|----------|-------------|
+| `# H1` | Title only (not in body) |
+| `## H2` - `###### H6` | `<h2>` |
+| `**bold**` | `<strong>` |
+| `*italic*` | `<em>` |
+| `[text](url)` | `<a href>` |
+| `> quote` | `<blockquote>` |
+| `` `code` `` | `<code>` |
+| ```` ``` ```` | `<blockquote>` (X limitation) |
+| `- item` | `<ul><li>` |
+| `1. item` | `<ol><li>` |
+| `![](img)` | Image placeholder |
+
+## Workflow
+
+1. **Parse Markdown**: Extract title, cover, content images, generate HTML
+2. **Launch Chrome**: Real browser with CDP, persistent login
+3. **Navigate**: Open `x.com/compose/articles`
+4. **Create Article**: Click create button if on list page
+5. **Upload Cover**: Use file input for cover image
+6. **Fill Title**: Type title into title field
+7. **Paste Content**: Copy HTML to clipboard, paste into editor
+8. **Insert Images**: For each placeholder (reverse order):
+   - Find placeholder text in editor
+   - Select the placeholder
+   - Copy image to clipboard
+   - Paste to replace selection
+9. **Review**: Browser stays open for 60s preview
+10. **Publish**: Only with `--submit` flag
+
+## Example Session
+
+```
+User: /post-to-x article ./blog/my-post.md --cover ./thumbnail.png
+
+Claude:
+1. Parses markdown: title="My Post", 3 content images
+2. Launches Chrome with CDP
+3. Navigates to x.com/compose/articles
+4. Clicks create button
+5. Uploads thumbnail.png as cover
+6. Fills title "My Post"
+7. Pastes HTML content
+8. Inserts 3 images at placeholder positions
+9. Reports: "Article composed. Review and use --submit to publish."
+```
+
+## Troubleshooting
+
+- **No create button**: Ensure X Premium subscription is active
+- **Cover upload fails**: Check file path and format (PNG, JPEG)
+- **Images not inserting**: Verify placeholders exist in pasted content
+- **Content not pasting**: Check HTML clipboard: `npx -y bun ${SKILL_DIR}/scripts/copy-to-clipboard.ts html --file /tmp/test.html`
+
+## How It Works
+
+1. `md-to-html.ts` converts Markdown to HTML:
+   - Extracts frontmatter (title, cover)
+   - Converts markdown to HTML
+   - Replaces images with unique placeholders
+   - Downloads remote images locally
+   - Returns structured JSON
+
+2. `x-article.ts` publishes via CDP:
+   - Launches real Chrome (bypasses detection)
+   - Uses persistent profile (saved login)
+   - Navigates and fills editor via DOM manipulation
+   - Pastes HTML from system clipboard
+   - Finds/selects/replaces each image placeholder

+# Regular Posts - Detailed Guide
+
+Detailed documentation for posting text and images to X.
+
+## Manual Workflow
+
+If you prefer step-by-step control:
+
+### Step 1: Copy Image to Clipboard
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/copy-to-clipboard.ts image /path/to/image.png
+```
+
+### Step 2: Paste from Clipboard
+
+```bash
+# Simple paste to frontmost app
+npx -y bun ${SKILL_DIR}/scripts/paste-from-clipboard.ts
+
+# Paste to Chrome with retries
+npx -y bun ${SKILL_DIR}/scripts/paste-from-clipboard.ts --app "Google Chrome" --retries 5
+
+# Quick paste with shorter delay
+npx -y bun ${SKILL_DIR}/scripts/paste-from-clipboard.ts --delay 200
+```
+
+### Step 3: Use Playwright MCP (if Chrome session available)
+
+```bash
+# Navigate
+mcp__playwright__browser_navigate url="https://x.com/compose/post"
+
+# Get element refs
+mcp__playwright__browser_snapshot
+
+# Type text
+mcp__playwright__browser_click element="editor" ref="<ref>"
+mcp__playwright__browser_type element="editor" ref="<ref>" text="Your content"
+
+# Paste image (after copying to clipboard)
+mcp__playwright__browser_press_key key="Meta+v"  # macOS
+# or
+mcp__playwright__browser_press_key key="Control+v"  # Windows/Linux
+
+# Screenshot to verify
+mcp__playwright__browser_take_screenshot filename="preview.png"
+```
+
+## Image Support
+
+- Formats: PNG, JPEG, GIF, WebP
+- Max 4 images per post
+- Images copied to system clipboard, then pasted via keyboard shortcut
+
+## Example Session
+
+```
+User: /post-to-x "Hello from Claude!" --image ./screenshot.png
+
+Claude:
+1. Runs: npx -y bun ${SKILL_DIR}/scripts/x-browser.ts "Hello from Claude!" --image ./screenshot.png
+2. Chrome opens with X compose page
+3. Text is typed into editor
+4. Image is copied to clipboard and pasted
+5. Browser stays open 30s for preview
+6. Reports: "Post composed. Use --submit to post."
+```
+
+## Troubleshooting
+
+- **Chrome not found**: Set `X_BROWSER_CHROME_PATH` environment variable
+- **Not logged in**: First run opens Chrome - log in manually, cookies are saved
+- **Image paste fails**:
+  - Verify clipboard script: `npx -y bun ${SKILL_DIR}/scripts/copy-to-clipboard.ts image <path>`
+  - On macOS, grant "Accessibility" permission to Terminal/iTerm in System Settings > Privacy & Security > Accessibility
+  - Keep Chrome window visible and in front during paste operations
+- **osascript permission denied**: Grant Terminal accessibility permissions in System Preferences
+- **Rate limited**: Wait a few minutes before retrying
+
+## How It Works
+
+The `x-browser.ts` script uses Chrome DevTools Protocol (CDP) to:
+1. Launch real Chrome (not Playwright) with `--disable-blink-features=AutomationControlled`
+2. Use persistent profile directory for saved login sessions
+3. Interact with X via CDP commands (Runtime.evaluate, Input.dispatchKeyEvent)
+4. **Paste images using osascript** (macOS): Sends real Cmd+V keystroke to Chrome, bypassing CDP's synthetic events that X can detect
+
+This approach bypasses X's anti-automation detection that blocks Playwright/Puppeteer.
+
+### Image Paste Mechanism (macOS)
+
+CDP's `Input.dispatchKeyEvent` sends "synthetic" keyboard events that websites can detect. X ignores synthetic paste events for security. The solution:
+
+1. Copy image to system clipboard via Swift/AppKit (`copy-to-clipboard.ts`)
+2. Bring Chrome to front via `osascript`
+3. Send real Cmd+V keystroke via `osascript` and System Events
+4. Wait for upload to complete
+
+This requires Terminal to have "Accessibility" permission in System Settings.

+## 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
+
+## File Management
+
+### With Content Path
+
+Save to `slide-deck/` subdirectory in the same folder as the content:
+
+```

+
+## Workflow
+
+### Step 1: Analyze Content & Determine Settings
+
+1. Read source material
+2. **Style selection**:
+   - If `--style` specified, use that style
+   - Otherwise, scan for style signals and auto-select
+3. **Language detection**:
+   - If `--lang` specified, use that language for all prompts and slide text
+   - Otherwise, detect language from source material
+   - If uncertain (mixed languages or unclear), ask user to confirm
+4. **Slide count**:
+   - If `--slides` specified, use that count
+   - Otherwise, dynamic based on content structure
+
+### Step 2: Generate Outline with Style Instructions
+
+Create outline with structured STYLE_INSTRUCTIONS block:
+
+```markdown
+# Slide Deck Outline
+
+**Topic**: [topic description]
+**Style**: [selected style]
+**Audience**: [target audience]
+**Language**: [output language]
+**Slide Count**: N slides
+**Generated**: YYYY-MM-DD HH:mm

+
+### Step 3: Save Outline
+
+Save outline as `outline.md` in the output directory.
+
+If `--outline-only` is specified, stop here.
+
+### Step 4: Generate Prompts
+
+Create prompt file per slide in `prompts/` directory:
+
+1. Read `references/base-prompt.md`
+2. Combine with style-specific instructions from outline
+3. Add slide-specific content from outline
+4. Save as `01-slide-cover.md`, `02-slide-{slug}.md`, etc.
+
+### Step 5: Generate Images
+
+**Image Generation Skill Selection**:
+1. Check available image generation skills
+2. If multiple skills available, ask user to choose
+
+**Session Management**:
+If the image generation skill supports `--sessionId`:
+1. Generate a unique session ID at the start (e.g., `slides-{topic-slug}-{timestamp}`)
+2. Use the same session ID for all slides in the series
+3. This ensures style consistency across all generated slides
+
+**Generation Flow**:
+1. Call selected image generation skill with prompt file, output path, and session ID
+2. Confirm generation success
+3. Report progress: "Generated X/N"
+4. Continue to next
+
+### Step 6: Merge to PPTX and PDF
+
+After all images are generated, merge them into PowerPoint and PDF files:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/merge-to-pptx.ts <slide-deck-dir>
+npx -y bun ${SKILL_DIR}/scripts/merge-to-pdf.ts <slide-deck-dir>
+```
+
+This creates:
+- `{topic-slug}.pptx` - PowerPoint with all images as full-bleed 16:9 slides and prompt content as speaker notes
+- `{topic-slug}.pdf` - PDF with all images as full-page slides
+
+### Step 7: Output Summary
+
+```
+Slide Deck Complete!

+Style: [style name]
+Audience: [audience type]

+```
+
+## Content Rules
+
+1. **Respect reader attention** - 
+2. **Data traceability** - All statistics must include source attribution
+3. **Self-contained prompts** - Every detail in the image prompt, no external references
+4. **No placeholders** - Every element must be fully specified
+
+## Style Rules
+
+1. **Narrative headlines** - Headlines tell the story, not label the content
+   - Bad: "Key Statistics"
+   - Good: "Usage doubled in 6 months"
+
+2. **Avoid AI clichés** - No "dive into", "explore", "journey", "let's"
+
+3. **Meaningful back cover** - Not just "Thank you"
+   - Include call-to-action, key takeaway, or memorable closing
+
+4. **Consistent visual language** - Same icons, colors, layouts throughout
+
+## Slide Structure
+
+1. **Cover (Slide 1)**: Title, visual hook, topic introduction
+2. **Content (Middle)**: Key points, data, explanations - dynamic count based on content
+3. **Back Cover (Final)**: Summary, call-to-action, or memorable closing
+
+## Key Specifications
+
+- **Aspect Ratio**: 16:9 (landscape)
+- **Slide Count**: Dynamic based on content
+- **Required Slides**: Cover + Back Cover minimum
+- **No slide numbers, footers, or logos**
+- **Language**: Priority order: `--lang` option → source material language → ask user if uncertain
+- **Tone**: Direct, confident language (avoid AI-sounding phrases)

+
+## Image Specifications
+
+- **Type**: Presentation slide
+- **Aspect Ratio**: 16:9 (landscape)
+- **Style**: Professional slide deck
+
+## Core Persona: The Architect
+
+You are "The Architect" - a master visual storyteller creating presentation slides. Your slides:
+- Tell a visual story that complements the narrative
+- Use bold, confident visual language
+- Balance information density with visual clarity
+- Create memorable, impactful visuals
+
+## Core Principles
+
+- Hand-drawn quality throughout - NO realistic or photographic elements
+- If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
+- NO slide numbers, page numbers, footers, headers, or logos
+- Clean, uncluttered layouts with clear visual hierarchy
+- Each slide conveys ONE clear message
+
+## Text Style (CRITICAL)
+
+- **ALL text MUST match the designated style exactly**
+- Title text: Large, bold, immediately readable
+- Body text: Clear, legible, appropriate sizing
+- Max 3-4 text elements per slide
+- **DO NOT use realistic or computer-generated fonts unless style specifies**
+- **Font rendering must match the style aesthetic** (hand-drawn for sketch styles, clean for minimal styles)
+
+## Layout Principles
+
+- **Visual Hierarchy**: Most important element gets most visual weight
+- **Breathing Room**: Generous margins and spacing between elements
+- **Alignment**: Consistent alignment creates professional feel
+- **Balance**: Distribute visual weight evenly (symmetrical or asymmetrical)
+- **Focal Point**: One clear area draws the eye first
+- **Rule of Thirds**: Key elements at intersection points for dynamic compositions
+- **Z-Pattern**: For text-heavy slides, arrange content in natural reading flow
+
+## Language
+
+- Use the same language as the content provided below for all text elements
+- Match punctuation style to the content language
+- Write in direct, confident language
+- Avoid AI-sounding phrases like "dive into", "explore", "let's", "journey"

+## File Management
+
+### With Article Path
+
+Save to `xhs-images/` subdirectory in the same folder as the article:
+
+```
+posts/ai-future/
+├── article.md
+└── xhs-images/
+    ├── outline.md
+    ├── prompts/
+    │   ├── 01-cover.md
+    │   ├── 02-content-1.md
+    │   └── ...
+    ├── 01-cover.png
+    ├── 02-content-1.png
+    └── 03-ending.png
+```
+
+### Without Article Path
+
+Save to `xhs-outputs/YYYY-MM-DD/[topic-slug]/`:
+
+```
+xhs-outputs/

+        ├── 01-cover.png
+        └── 02-ending.png
+```
+
+## Workflow
+
+### Step 1: Analyze Content & Select Style/Layout
+
+1. Read content
+2. If `--style` specified, use that style; otherwise auto-select
+3. If `--layout` specified, use that layout; otherwise auto-select per image
+4. Determine image count based on content complexity:
+
+| Content Type | Image Count |
+|-------------|-------------|
+| Simple opinion / single topic | 2-3 |
+| Medium complexity / tutorial | 4-6 |
+| Deep dive / multi-dimensional | 7-10 |
+
+**Note**: Layout can vary per image in a series. Cover typically uses `sparse`, content pages use `balanced`/`dense`/`list` as appropriate.
+
+### Step 2: Generate Outline
+
+Plan for each image with style and layout specifications:
+
+```markdown
+# Xiaohongshu Infographic Series Outline
+
+**Topic**: [topic description]
+**Style**: [selected style]
+**Default Layout**: [selected layout or "varies"]
+**Image Count**: N
+**Generated**: YYYY-MM-DD HH:mm
+
+---
+
+## Image 1 of N
+
+**Position**: Cover
+**Layout**: sparse
+**Core Message**: [one-liner]
+**Filename**: 01-cover.png
+
+**Text Content**:
+- Title: xxx
+- Subtitle: xxx
+
+**Visual Concept**: [style + layout appropriate description]
+
+---
+
+## Image 2 of N
+
+**Position**: Content
+**Layout**: [balanced/dense/list/comparison/flow]
+**Core Message**: [one-liner]
+**Filename**: 02-xxx.png
+
+**Text Content**:
+- Title: xxx
+- Points: [list based on layout density]
+
+**Visual Concept**: [description matching style + layout]
+
+---
+...
+```
+
+### Step 3: Save Outline
+
+Save outline as `outline.md`.
+
+### Step 4: Generate Images One by One
+
+For each image, create a prompt file with style and layout specifications.
+
+**Prompt Format**:
+
+```markdown
+Infographic theme: [topic]
+Style: [style name]
+Layout: [layout name]
+Position: [cover/content/ending]
+
+Visual composition:
+- Main visual: [style-appropriate description]
+- Arrangement: [layout-specific structure]
+- Decorative elements: [style-specific decorations]
+
+Color scheme:
+- Primary: [style primary color]
+- Background: [style background color]
+- Accent: [style accent color]
+
+Text content:
+- Title: 「xxx」(large, prominent)
+- Key points: [based on layout density]
+
+Layout instructions: [layout-specific guidance]
+Style notes: [style-specific characteristics]
+```
+
+**Layout-Specific Instructions**:
+
+| Layout | Arrangement Instructions |
+|--------|-------------------------|
+| `sparse` | Single focal point centered, 1-2 text elements, maximum breathing room |
+| `balanced` | Title at top, 3-4 points in clear sections, moderate spacing |
+| `dense` | Grid or multi-section layout, 5-8 points, compact but organized |
+| `list` | Vertical numbered/bulleted list, consistent item spacing, clear hierarchy |
+| `comparison` | Two-column split, clear divider, mirrored structure left/right |
+| `flow` | Horizontal or vertical flow with arrows, connected nodes/steps |
+
+**Image Generation Skill Selection**:
+1. Check available image generation skills
+2. If multiple skills available, ask user to choose
+
+**Session Management**:
+If the image generation skill supports `--sessionId`:
+1. Generate a unique session ID at the start (e.g., `xhs-{topic-slug}-{timestamp}`)
+2. Use the same session ID for all images in the series
+3. This ensures style consistency across all generated images
+
+**Generation Flow**:
+1. Call selected image generation skill with prompt file, output path, and session ID
+2. Confirm generation success
+3. Report progress: "Generated X/N"
+4. Continue to next
+
+### Step 5: Completion Report
+
+```
+Xiaohongshu Infographic Series Complete!

+
+Outline: outline.md
+```
+
+## Content Breakdown Principles
+
+1. **Cover (Image 1)**: Strong visual impact, core title, attention hook → `sparse` layout
+2. **Content (Middle)**: Core points per image, density varies by content → `balanced`/`dense`/`list`/`comparison`/`flow`
+3. **Ending (Last)**: Summary / call-to-action / memorable quote → `sparse` or `balanced`
+
+**Style × Layout Matrix** (recommended combinations):
+
+| | sparse | balanced | dense | list | comparison | flow |
+|---|:---:|:---:|:---:|:---:|:---:|:---:|
+| cute | ✓✓ | ✓✓ | ✓ | ✓✓ | ✓ | ✓ |
