Workflow Checklist

Copy this checklist to track progress:

CopyProgress:
- [ ] Step 1: Analyze Markdown structure and images
- [ ] Step 2: Confirm conversion mode (API/AI) and theme
- [ ] Step 3: Generate HTML with inline CSS
- [ ] Step 4: Process images (upload to WeChat)
- [ ] Step 5: Replace image URLs in HTML
- [ ] Step 6: Preview or upload to draft

---

Step 1: Analyze Markdown

Read the markdown file and extract:

Image Reference Types:

---

Step 2: Confirm Mode and Theme

Conversion Mode

AI Themes

API Themes (Fast)

Ask the user: "Which mode and theme would you like?" - Only ask if the user doesn't specify in their request.

• API mode (fast): default, bytedance, apple, sports, chinese, cyber
• AI mode (themed): autumn-warm, spring-fresh, ocean-calm

Default: Use API mode if user doesn't specify.

Read detailed style prompts from references/themes.md

---

Step 3: Generate HTML

API Mode

Call md2wechat CLI:

Copybash skill/md2wechat/scripts/run.sh convert article.md --mode api

AI Mode

Read the selected style prompt from references/themes.md and generate HTML with inline CSS.

Important Rules:

1. All CSS must be inline (in style attributes)
2. No external stylesheets or scripts
3. Use WeChat-safe HTML tags only
4. Image placeholder format: <!-- IMG:0 -->, <!-- IMG:1 -->, etc.

Safe HTML Tags:

• <p>, <br>, <strong>, <em>, <u>, <a>
• <h1> to <h6>
• <ul>, <ol>, <li>
• <blockquote>, <pre>, <code>
• <table>, <thead>, <tbody>, <tr>, <th>, <td>
• <section>, <span> (with inline styles)

Avoid:

• <script>, <iframe>, <form>
• External CSS/JS references
• Complex positioning (fixed, absolute)

Critical for WeChat:

• Create a main <div> container immediately after <body> to hold all global styles
• Specify color explicitly for each <p> tag (WeChat resets to black otherwise)
• Use two <span> tags for heading symbols: one with color+text-shadow, one with solid color

Step 4: Process Images

Image Generation Methods

There are three ways to generate AI images:

Method 1: Natural Language - For Article (Recommended)

Simply describe what you want in plain language:

CopyUser: "Generate a product concept image at the beginning of article.md"

User: "Add a comparison chart after the third paragraph"

User: "Create an image showing the workflow diagram in article.md"

How I process natural language requests:

1. Understand the intent - Identify where to insert the image
2. Read the article - Analyze context to create an appropriate prompt
3. Insert the syntax - Add ![alt](__generate:prompt__) at the correct location
4. Show the prompt - Display the generated prompt for transparency
5. Generate and upload - Call the conversion command to complete

Note: Proceed directly with generation. Only ask for confirmation if the prompt is complex or ambiguous.

Example conversation:

CopyUser: "Add a product image at the start of my article"
Claude: "I'll add a product concept image at the beginning of article.md.
Based on your article about 'Smart Home Hub', I'll use this prompt:
'A modern smart home hub device, sleek white design with LED indicator
lights, minimalist product photography on a clean white background'
I'll proceed with generating the image."

Method 2: Natural Language - Standalone Image

Generate an image without any article:

CopyUser: "Generate an image of a cute cat sitting on a windowsill"
User: "Create a product concept: modern smart home device"
User: "Make a diagram showing user signup flow"

I will:

1. Create an appropriate prompt based on your description
2. Call: bash skill/md2wechat/scripts/run.sh generate_image "prompt"
3. Return the WeChat URL and media ID

Use when: You just need an image, not for any article.

Method 3: Manual Syntax

Write the image generation syntax directly in Markdown:

Copy![Product Concept](__generate:A futuristic smart home hub device, sleek design__)

Syntax format: ![alt text](__generate:prompt__)

---

Processing Images by Type

For each image reference in order:

Local Image

Copybash skill/md2wechat/scripts/run.sh upload_image "/path/to/image.png"

Response:

Copy{"success": true, "wechat_url": "https://mmbiz.qpic.cn/...", "media_id": "xxx"}

Online Image

Copybash skill/md2wechat/scripts/run.sh download_and_upload "https://example.com/image.png"

AI Generated Image (via CLI)

Copy# Generate with default size (2048x2048 square)
bash skill/md2wechat/scripts/run.sh generate_image "A cute cat sitting on a windowsill"

# Generate with 16:9 ratio for WeChat cover (recommended)
bash skill/md2wechat/scripts/run.sh generate_image --size 2560x1440 "prompt"

WeChat Cover Images: For article covers, use 16:9 horizontal ratio (2560x1440 recommended) as it displays better in WeChat's feed and article list. Square images (2048x2048) are cropped in preview.

Note: AI image generation requires IMAGE_API_KEY environment variable.

Image Processing Pipeline:

1. If AI generation: Call image API → get URL
2. If online: Download image to temp
3. If local: Read file
4. Compress if width > 1920px (configurable)
5. Upload to WeChat material API
6. Return wechat_url and media_id
7. Store result for HTML replacement

---

Step 5: Replace Image URLs

Replace placeholders in HTML:

Copy<!-- Before -->
<!-- IMG:0 -->
<!-- IMG:1 -->

<!-- After -->
<img src="https://mmbiz.qpic.cn/..." />
<img src="https://mmbiz.qpic.cn/..." />

Use the WeChat URLs returned from image processing.

---

Step 6: Preview or Upload

Ask user:

1. Preview only - Show HTML for review
2. Upload to draft - Create WeChat draft article

Preview Mode

Display HTML in markdown code block for user to copy.

Upload Mode

Create draft and run:

Copybash skill/md2wechat/scripts/run.sh convert article.md --draft --cover cover.jpg

Required for draft:

• WECHAT_APPID environment variable

Troubleshooting

Configuration Issues

Q: "AppID not configured" error A: Set WECHAT_APPID and WECHAT_SECRET environment variables, or run:

Copybash skill/md2wechat/scripts/run.sh config init

Q: Config file not working A: Check config file location. Supported locations:

• ./md2wechat.yaml (current directory, highest priority)
• ~/.md2wechat.yaml
• ~/.config/md2wechat/config.yaml

Image Issues

Q: Image upload fails with "invalid filetype" A: WeChat supports JPG, PNG, GIF. Ensure image is in correct format:

Copy# Convert using ImageMagick
convert input.tiff output.jpg

Q: Images not showing in draft A: Images must use WeChat-hosted URLs (mmbiz.qpic.cn), not external URLs.

Q: AI image generation fails A: Check IMAGE_API_KEY is set and API base URL is correct.

WeChat API Issues

Q: "IP not in whitelist" error A: Add your server IP to WeChat whitelist:

1. Get your public IP:

Copycurl ifconfig.me
# or
curl ip.sb

1. Add IP to WeChat:
   • Visit WeChat Developer Platform
   • Go to Settings & Development → Basic Configuration
   • Find IP Whitelist section
   • Click "Set" and add your IP
   • Wait a few minutes for changes to take effect

Q: "access_token expired" error A: Program auto-refreshes tokens. If persists:

Copy# Check config
bash skill/md2wechat/scripts/run.sh config show

# Re-init if needed
bash skill/md2wechat/scripts/run.sh config init

Q: "create draft failed" error A: Possible causes:

1. Insufficient permissions - ensure account is verified
2. Sensitive content - check article content
3. Draft limit reached - check existing drafts

Q: API rate limit exceeded A: WeChat has API limits. Wait and retry:

Copy# Wait 60 seconds
sleep 60
# Retry
bash skill/md2wechat/scripts/run.sh convert article.md --draft

HTML/Style Issues

Q: Styles not working in WeChat editor A: Check:

1. CSS uses inline style attributes (not <style> tags)
2. CSS properties are in allowed list (see HTML Guide)
3. No syntax errors (unclosed tags, etc.)

Q: Background color lost in WeChat A: WeChat strips <body> styles. Use main container:

Copy<div style="background-color: #faf9f5; padding: 40px 10px;">
  <!-- All content here -->
</div>

Q: Text color not as expected A: WeChat resets <p> color to black. Always specify:

Copy<p style="color: #4a413d;">Your text here</p>

Command Issues

Q: "command not found: md2wechat" A: The run.sh script will auto-download the binary on first run. If you want to install manually:

Copy# Use the script - it will handle installation
bash skill/md2wechat/scripts/run.sh --help

# Or download from releases
# Visit: https://github.com/geekjourneyx/md2wechat-skill/releases

Q: AI mode very slow A: AI mode requires Claude API call and takes 10-30 seconds. For faster results, use API mode.
