--- name: xiaohongshu-images description: Transform markdown/HTML into styled 3:4 ratio images for Xiaohongshu --- # Xiaohongshu Images Skill This skill transforms markdown, HTML, or text content into beautifully styled HTML pages with AI-generated cover images, then captures them as sequential screenshots at 3:4 ratio for Xiaohongshu posting. ## Overview The skill performs the following workflow: 1. **Accept Content**: Receives markdown, HTML, or txt format content from the user 2. **Load Prompt Template**: Reads the prompt template from `prompts/default.md` in this skill's directory 3. **Generate Cover Image**: Uses `/baoyu-cover-image` skill to generate a cover image based on the article content 4. **Generate HTML**: Creates a beautifully styled HTML page following the prompt template specifications 5. **Save Output**: Saves the HTML to `~/Dev/obsidian/articles//xhs-preview.html` 6. **Capture Screenshots**: Takes sequential 3:4 ratio screenshots of the entire page without cutting text ## Usage When the user invokes this skill, follow these steps: ### Step 1: Identify the Input The user will provide one of the following: - A file path to a markdown, HTML, or txt file (e.g., `/path/to/article.md`) - Raw content directly in the conversation - A URL to fetch content from If the input is unclear, ask the user to provide either a file path, URL, or paste the content directly. ### Step 2: Read the Prompt Template Read the prompt template from this skill's directory: ``` {{SKILL_DIR}}/prompts/default.md ``` Use the Read tool to get the prompt template content. This template defines the HTML/CSS styling specifications. ### Step 3: Extract Article Title and Date From the content, extract: - **Title**: The main heading (h1) or first significant title in the content - **Date**: Current date in YYYY-MM-DD format Create the output folder path as: `~/Dev/obsidian/articles/-/` - Replace spaces with hyphens - Remove special characters - Keep the title reasonably short (max 50 characters) - All images go in `_attachments/` subfolder ### Step 4: Generate Cover Image with baoyu-cover-image Skill **⚠️ COMPLIANCE CHECK**: Before generating, ensure the image concept complies with Xiaohongshu community guidelines (Section 11 of the prompt template). The image must: - Be age-appropriate with no revealing clothing or suggestive poses - Avoid political symbols, violence, gambling, smoking, or alcohol abuse - Convey positive, constructive messages - Be culturally sensitive and original Use the `/baoyu-cover-image` skill to generate the cover image: 1. **Invoke the skill** with the article content: ```bash /baoyu-cover-image ~/Dev/obsidian/articles/-/index.md --style <auto-or-specified> --no-title ``` Or if the content is not yet saved, pass the content directly to the skill. 2. **Style Selection**: - Let baoyu-cover-image auto-select based on content signals, OR - Specify a style that matches the article tone: - `tech` - AI, coding, digital topics - `warm` - Personal stories, emotional content - `bold` - Controversial, attention-grabbing topics - `minimal` - Simple, zen-like content - `playful` - Fun, casual, beginner-friendly content - `nature` - Wellness, health, organic topics - `retro` - History, vintage, traditional topics - `elegant` - Business, professional content (default) **Special: Mom Reading Club Template** When using the `mom-reading-club` template, override the default cover style with **calligraphy & ink-wash illustration (书法水墨风)**: ```bash /baoyu-cover-image <article> --style minimal --no-title --custom-prompt "Chinese calligraphy and ink-wash illustration style (书法水墨风). Zen-like simplicity with generous white space (留白). Include subtle ink-wash brush strokes as background texture. Minimalist botanical elements (bamboo, plum blossoms, orchids, lotus) when appropriate. Color palette: ink black (#1a1a1a), warm gray (#666666), subtle gold accents (#C9A962), warm off-white background (#F5F3EE). If human figures are included, depict an elegant woman aged 30-45 with a contemplative, refined demeanor. NO TEXT on the cover." ``` 3. **Use `--no-title` flag** since Xiaohongshu covers typically use visual-only images without embedded text. 4. **Move the generated image** to the correct location: - baoyu-cover-image saves to `imgs/cover.png` relative to the article - Move/copy to `~/Dev/obsidian/articles/<date>-<title>/_attachments/cover-xhs.png` ```bash mv ~/Dev/obsidian/articles/<date>-<title>/imgs/cover.png ~/Dev/obsidian/articles/<date>-<title>/_attachments/cover-xhs.png ``` ### Step 5: Generate HTML **⚠️ COMPLIANCE CHECK**: Before generating HTML, review the text content for compliance: - No absolute/superlative claims (最好、第一、国家级、最高级、全网最低价) - No exaggerated effect claims (一分钟见效、吃完就变白) - No false or unverified medical/financial advice - No defamatory or offensive language - If health/investment topics are involved, add disclaimer text Using the prompt template and the user's content: 1. **Parse the content** to identify: - Title (h1) - Subtitles (h2-h6) - Paragraphs - Lists - Code blocks - Links - Emphasis/bold text - Blockquotes 2. **Generate complete HTML** following the template specifications: - Dark gradient background - 600px × 800px cream-colored card - Proper typography with Google Fonts (Noto Serif SC, Inter, JetBrains Mono) - Cover image at the top - All specified styling for text, links, lists, code blocks, etc. - Responsive design for mobile 3. **Important HTML Structure**: ```html <!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Article Title
Cover
``` 4. **Save the HTML** to `~/Dev/obsidian/articles/-/xhs-preview.html` ### Step 6: Take Screenshots After generating the HTML, capture sequential screenshots of the `.container` element at **exact 3:4 aspect ratio**: **Screenshot Specifications:** - Container viewport: 600px × 800px (3:4 ratio) - Output resolution: 1200px × 1600px (2x device scale factor) - Each screenshot captures exactly the `.container` element, not the full page **Capture Process:** 1. **Open the HTML page** using Playwright browser with viewport larger than container 2. **Configure browser context**: - Viewport: 800px × 1000px (larger than container to ensure full visibility) - Device scale factor: 2x for high-resolution output 3. **Scroll within the container**: - The `.container` element has `overflow-y: auto`, making it internally scrollable - Start from `scrollTop = 0` and increment through the content - Each scroll position captures one 3:4 ratio screenshot 4. **Smart text boundary detection**: - Before each screenshot, analyze visible block elements (p, h1-h6, li, blockquote, pre, img) - If an element would be cut at the bottom boundary, end the current screenshot before that element - Add whitespace mask to cover partial content, maintaining clean 3:4 frame - Next screenshot starts with the cut element at the top 5. **Capture the complete `.container` content**: - Use `container.screenshot()` to capture only the container element (excludes page background) - Continue until all content is captured (scrollTop reaches scrollHeight - clientHeight) 6. **Save screenshots** to `~/Dev/obsidian/articles/<date>-<title>/_attachments/`: - Sequential naming: `xhs-01.png`, `xhs-02.png`, `xhs-03.png`, etc. **Use the screenshot script:** ```bash cd {{SKILL_DIR}} && python scripts/screenshot.py ~/Dev/obsidian/articles/<date>-<title>/xhs-preview.html ``` **Script Output:** - Each screenshot: exactly 1200×1600 pixels (3:4 ratio at 2x scale) - Only the cream-colored card content is captured - No text is cut off between screenshots ### Step 7: Report Results After completion, report to the user: - HTML file location - Number of screenshots generated - Screenshots folder location - Preview of the first screenshot (if possible) ## Directory Structure ``` {{SKILL_DIR}}/ ├── SKILL.md # This file ├── prompts/ │ └── default.md # Default HTML/CSS styling prompt ├── scripts/ │ └── screenshot.py # Screenshot capture script └── .gitignore Output directory (outside skill folder): ~/Dev/obsidian/articles/<date>-<title>/ ├── xhs-preview.html # Styled HTML preview page ├── imgs/ # Created by baoyu-cover-image │ ├── prompts/ │ │ └── cover.md # Cover image prompt │ └── cover.png # Generated cover (moved to _attachments/) └── _attachments/ # Obsidian-style attachments folder ├── cover-xhs.png # Cover image (moved from imgs/cover.png) ├── xhs-01.png # Screenshot page 1 (1200×1600) ├── xhs-02.png # Screenshot page 2 └── ... ``` ## Dependencies This skill depends on: - `/baoyu-cover-image` skill for cover image generation (must be installed in `~/.claude/skills/`) ## Example Workflow **User:** Create a styled article page from this markdown: ```markdown # My Article Title This is the introduction paragraph... ## Section 1 Content for section 1... ``` **Assistant Actions:** 1.
