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/<date-article-title>/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/<date>-<sanitized-title>/
- 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:

/baoyu-cover-image ~/Dev/obsidian/articles/<date>-<title>/index.md --style <auto-or-specified> --no-title

Or if the content is not yet saved, pass the content directly to the skill.

1. Style Selection:
2. Let baoyu-cover-image auto-select based on content signals, OR
3. 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."

1. Use --no-title flag since Xiaohongshu covers typically use visual-only images without embedded text.

2. Move the generated image to the correct location:

3. baoyu-cover-image saves to imgs/cover.png relative to the article
4. Move/copy to ~/Dev/obsidian/articles/<date>-<title>/_attachments/cover-xhs.png

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:
2. Title (h1)
3. Subtitles (h2-h6)
4. Paragraphs
5. Lists
6. Code blocks
7. Links
8. Emphasis/bold text

9. Blockquotes

10. Generate complete HTML following the template specifications:

11. Dark gradient background
12. 600px × 800px cream-colored card
13. Proper typography with Google Fonts (Noto Serif SC, Inter, JetBrains Mono)
14. Cover image at the top
15. All specified styling for text, links, lists, code blocks, etc.

16. Responsive design for mobile

17. Important HTML Structure:

<!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</title>
    <!-- Google Fonts -->
    <link href="https://fonts.googleapis.com/css2?family=Noto+Serif+SC:wght@700&family=Inter:wght@300;400;700;800&family=JetBrains+Mono:wght@400;700&display=swap" rel="stylesheet">
    <style>
        /* All CSS styles inline */
    </style>
</head>
<body>
    <div class="container">
        <img src="_attachments/cover-xhs.png" class="cover-image" alt="Cover">
        <div class="content">
            <!-- Article content -->
        </div>
    </div>
</body>
</html>

1. Save the HTML to ~/Dev/obsidian/articles/<date>-<title>/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:
3. Viewport: 800px × 1000px (larger than container to ensure full visibility)
4. Device scale factor: 2x for high-resolution output
5. Scroll within the container:
6. The .container element has overflow-y: auto, making it internally scrollable
7. Start from scrollTop = 0 and increment through the content
8. Each scroll position captures one 3:4 ratio screenshot
9. Smart text boundary detection:
10. Before each screenshot, analyze visible block elements (p, h1-h6, li, blockquote, pre, img)
11. If an element would be cut at the bottom boundary, end the current screenshot before that element
12. Add whitespace mask to cover partial content, maintaining clean 3:4 frame
13. Next screenshot starts with the cut element at the top
14. Capture the complete .container content:
15. Use container.screenshot() to capture only the container element (excludes page background)
16. Continue until all content is captured (scrollTop reaches scrollHeight - clientHeight)
17. Save screenshots to ~/Dev/obsidian/articles/<date>-<title>/_attachments/:
18. Sequential naming: xhs-01.png, xhs-02.png, xhs-03.png, etc.

Use the screenshot script:

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)
