+## Usage
+
+Claude performs content analysis and formatting (Steps 1-6), then runs the script for typography fixes (Step 7).
+
+## Workflow
+
+### Step 1: Read Source File
+
+Read the user-specified markdown or plain text file.
+
+### Step 1.5: Detect Content Type & Confirm
+
+**Content Type Detection:**
+
+| Indicator | Classification |
+|-----------|----------------|
+| Has `---` YAML frontmatter | Markdown |
+| Has `#`, `##`, `###` headings | Markdown |
+| Has `**bold**`, `*italic*` | Markdown |
+| Has `- ` or `1. ` lists | Markdown |
+| Has ``` code blocks | Markdown |
+| Has `> ` blockquotes | Markdown |
+| None of above | Plain text |
+
+**Decision Flow:**
+
+┌─────────────────┬────────────────────────────────────────────────┐
+│  Content Type   │                     Action                     │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Plain text      │ Proceed to Step 2 (format to markdown)         │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Markdown        │ Use AskUserQuestion to confirm optimization    │
+└─────────────────┴────────────────────────────────────────────────┘
+
+**If Markdown detected, ask user:**
+
+```
+Detected existing markdown formatting. What would you like to do?
+
+1. Optimize formatting (Recommended)
+   - Add/improve frontmatter, headings, bold, lists
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+2. Keep original formatting
+   - Preserve existing markdown structure
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+3. Typography fixes only
+   - Run typography script on original file in-place
+   - No copy created, modifies original file directly
+```
+
+**Based on user choice:**
+- **Optimize**: Continue to Step 2-8 (full workflow)
+- **Keep original**: Skip Steps 2-5, copy file → Step 6-8 (run script on copy)
+- **Typography only**: Skip Steps 2-6, run Step 7 on original file directly
+
+### Step 2: Analyze Content Structure
+
+Identify:
+- Existing title (H1 `#`)
+- Paragraph separations
+- Keywords suitable for **bold**
+- Parallel content convertible to lists
+- Code snippets
+- Quotations
+
+### Step 3: Check/Create Frontmatter
+
+Check for YAML frontmatter (`---` block). Create if missing.
+
+**Meta field handling:**
+
+| Field | Processing |
+|-------|------------|
+| `title` | See Step 4 |
+| `slug` | Infer from file path (e.g., `posts/2026/01/10/vibe-coding/` → `vibe-coding`) or generate from title |
+| `summary` | Generate engaging summary (100-150 characters) |
+| `featureImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path |
+
+### Step 4: Title Handling
+
+**Logic:**
+1. If frontmatter already has `title` → use it, no H1 in body
+2. If first line is H1 → extract to frontmatter `title`, remove H1 from body
+3. If neither exists → generate candidate titles
+
+**Title generation flow:**
+
+1. Generate 3 candidate titles based on content
+2. Use `AskUserQuestion` tool:
+
+```
+Select a title:
+
+1. [Title A] (Recommended)
+2. [Title B]
+3. [Title C]
+```
+
+3. If no selection within a few seconds, use recommended (option 1)
+
+**Title principles:**
+- Concise, max 20 characters
+- Captures core message
+- Engaging, sparks reading interest
+- Accurate, avoids clickbait
+
+**Important:** Once title is in frontmatter, body should NOT have H1 (avoid duplication)
+
+### Step 5: Format Processing
+
+**Formatting rules:**
+
+| Element | Format |
+|---------|--------|
+| Titles | Use `#`, `##`, `###` hierarchy |
+| Key points | Use `**bold**` |
+| Parallel items | Convert to `-` unordered or `1.` ordered lists |
+| Code/commands | Use `` `inline` `` or ` ```block``` ` |
+| Quotes/sayings | Use `>` blockquote |
+| Separators | Use `---` where appropriate |
+
+**Formatting principles:**
+- Preserve original content and viewpoints
+- Add formatting only, do not modify text
+- Formatting serves readability
+- Avoid over-formatting
+
+### Step 6: Save Formatted File
+
+Save as `{original-filename}-formatted.md`
+
+Examples:
+- `final.md` → `final-formatted.md`
+- `draft-v1.md` → `draft-v1-formatted.md`
+
+**If user chose "Keep original formatting" (from Step 1.5):**
+- Copy original file to `{filename}-formatted.md` without modifications
+- Proceed to Step 7 for typography fixes only
+
+**Backup existing file:**
+
+If `{filename}-formatted.md` already exists, backup before overwriting:
+
+```bash
+# Check if formatted file exists
+if [ -f "{filename}-formatted.md" ]; then
+  # Backup with timestamp
+  mv "{filename}-formatted.md" "{filename}-formatted.backup-$(date +%Y%m%d-%H%M%S).md"
+fi
+```
+
+Example:
+- `final-formatted.md` exists → backup to `final-formatted.backup-20260128-143052.md`
+
+### Step 7: Execute Text Formatting Script
+
+After saving, **must** run the formatting script:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts {output-file-path} [options]
+```
+
+**Script Options:**
+
+| Option | Short | Description | Default |
+|--------|-------|-------------|---------|
+| `--quotes` | `-q` | Replace ASCII quotes with fullwidth quotes `"..."` | false |
+| `--no-quotes` | | Do not replace quotes | |
+| `--spacing` | `-s` | Add CJK/English spacing via autocorrect | true |
+| `--no-spacing` | | Do not add CJK/English spacing | |
+| `--emphasis` | `-e` | Fix CJK emphasis punctuation issues | true |
+| `--no-emphasis` | | Do not fix CJK emphasis issues | |
+| `--help` | `-h` | Show help message | |
+
+**Examples:**
+
+```bash
+# Default: spacing + emphasis enabled, quotes disabled
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md
+
+# Enable all features including quote replacement
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --quotes
+
+# Only fix emphasis issues, skip spacing
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing
+
+# Disable all processing except frontmatter formatting
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing --no-emphasis
+```
+
+**Script performs (based on options):**
+1. Fix CJK emphasis/bold punctuation issues (default: enabled)
+2. Add CJK/English mixed text spacing via autocorrect (default: enabled)
+3. Replace ASCII quotes `"..."` with fullwidth quotes `"..."` (default: disabled)
+4. Format frontmatter YAML (always enabled)
+
+### Step 8: Display Results
+
+```
+**Formatting complete**
+
+File: posts/2026/01/09/example/final-formatted.md
+
+Changes:
+- Added title: [title content]
+- Added X bold markers
+- Added X lists
+- Added X code blocks
+```
+
+## Formatting Example
+
+**Before:**
+```
+This is plain text. First point is efficiency improvement. Second point is cost reduction. Third point is experience optimization. Use npm install to install dependencies.
+```
+
+**After:**
+```markdown
+---
+title: Three Core Advantages
+slug: three-core-advantages
+summary: Discover the three key benefits that drive success in modern projects.
+---
+
+This is plain text.
+
+**Main advantages:**
+- Efficiency improvement
+- Cost reduction
+- Experience optimization
+
+Use `npm install` to install dependencies.
+```
+
+## Notes
+
+- Preserve original writing style and tone
+- Specify correct language for code blocks (e.g., `python`, `javascript`)
+- Maintain CJK/English spacing standards
+- Do not add content not present in original
+
+## Extension Support
+
+Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.

+Converts Markdown files to beautifully styled HTML with inline CSS, optimized for WeChat Official Account and other platforms.
+
+## Script Directory
+
+**Agent Execution**: Determine this SKILL.md directory as `SKILL_DIR`, then use `${SKILL_DIR}/scripts/<name>.ts`.
+
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | Main entry point |
+
+## Preferences (EXTEND.md)
+
+Use Bash to check EXTEND.md existence (priority order):
+
+```bash
+# Check project-level first
+test -f .baoyu-skills/baoyu-markdown-to-html/EXTEND.md && echo "project"
+
+# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
+test -f "$HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.md" && echo "user"
+```

+
+## Workflow
+
+### Step 0: Pre-check (Chinese Content)
+
+**Condition**: Only execute if input file contains Chinese text.
+
+**Detection**:
+1. Read input markdown file
+2. Check if content contains CJK characters (Chinese/Japanese/Korean)
+3. If no CJK content → skip to Step 1
+
+**Format Suggestion**:
+
+If CJK content detected AND `baoyu-format-markdown` skill is available:
+
+Use `AskUserQuestion` to ask whether to format first. Formatting can fix:
+- Bold markers with punctuation inside causing `**` parse failures
+- CJK/English spacing issues
+
+**If user agrees**: Invoke `baoyu-format-markdown` skill to format the file, then use formatted file as input.
+
+**If user declines**: Continue with original file.
+
+### Step 1: Confirm Theme
+
+Before converting, use AskUserQuestion to confirm the theme (unless user already specified):
+
+| Theme | Description |
+|-------|-------------|
+| `default` (Recommended) | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
+| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 |
+| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 |
+
+### Step 2: Convert
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>
+```
+
+### Step 3: Report Result
+
+Display the output path from JSON result. If backup was created, mention it.
+
+## Usage
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> [options]
+```
+
+**Options:**
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `--theme <name>` | Theme name (default, grace, simple) | default |
+| `--title <title>` | Override title from frontmatter | |
+| `--keep-title` | Keep the first heading in content | false (removed) |
+| `--help` | Show help | |
+
+**Examples:**
+
+```bash
+# Basic conversion (uses default theme, removes first heading)
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md
+
+# With specific theme
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --theme grace
+
+# Keep the first heading in content
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --keep-title
+
+# Override title
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --title "My Article"
+```
+
+## Output
+
+**File location**: Same directory as input markdown file.
+- Input: `/path/to/article.md`
+- Output: `/path/to/article.html`
+
+**Conflict handling**: If HTML file already exists, it will be backed up first:
+- Backup: `/path/to/article.html.bak-YYYYMMDDHHMMSS`
+
+**JSON output to stdout:**
+
+```json
+{
+  "title": "Article Title",
+  "author": "Author Name",
+  "summary": "Article summary...",
+  "htmlPath": "/path/to/article.html",
+  "backupPath": "/path/to/article.html.bak-20260128180000",
+  "contentImages": [
+    {
+      "placeholder": "MDTOHTMLIMGPH_1",
+      "localPath": "/path/to/img.png",
+      "originalPath": "imgs/image.png"
+    }
+  ]
+}
+```
+
+## Themes
+
+| Theme | Description |
+|-------|-------------|
+| `default` | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
+| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 (by @brzhang) |
+| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 (by @okooo5km) |
+
+## Supported Markdown Features
+
+| Feature | Syntax |

-## Usage
+## Image-Text Posting (图文)
 
-### Image-Text (图文)
+For short posts with multiple images (up to 9):
 
 ```bash
 npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --markdown article.md --images ./images/
 npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit
 ```
 
-### Article (文章)
+See [references/image-text-posting.md](references/image-text-posting.md) for details.
 
-Before posting, ask user to choose a theme using AskUserQuestion:
+## Article Posting Workflow (文章)
+
+Copy this checklist and check off items as you complete them:
+
+```
+Publishing Progress:
+- [ ] Step 0: Load preferences (EXTEND.md)
+- [ ] Step 1: Determine input type
+- [ ] Step 2: Check markdown-to-html skill
+- [ ] Step 3: Convert to HTML
+- [ ] Step 4: Validate metadata (title, summary)
+- [ ] Step 5: Select method and configure credentials
+- [ ] Step 6: Publish to WeChat
+- [ ] Step 7: Report completion
+```
+
+### Step 0: Load Preferences
+
+Check and load EXTEND.md settings (see Preferences section above).
+
+### Step 1: Determine Input Type
+
+| Input Type | Detection | Action |
+|------------|-----------|--------|
+| HTML file | Path ends with `.html`, file exists | Skip to Step 4 |
+| Markdown file | Path ends with `.md`, file exists | Continue to Step 2 |
+| Plain text | Not a file path, or file doesn't exist | Save to markdown, then Step 2 |
+
+**Plain Text Handling**:
+
+1. Generate slug from content (first 2-4 meaningful words, kebab-case)
+2. Create directory and save file:
+
+```bash
+mkdir -p "$(pwd)/post-to-wechat/$(date +%Y-%m-%d)"
+# Save content to: post-to-wechat/yyyy-MM-dd/[slug].md
+```
+
+3. Continue processing as markdown file
+
+**Slug Examples**:
+- "Understanding AI Models" → `understanding-ai-models`
+- "人工智能的未来" → `ai-future` (translate to English for slug)
+
+### Step 2: Check Markdown-to-HTML Skill
+
+**Skip if**: Input is `.html` file
+
+**Skill Discovery**:
+
+```bash
+# Check if baoyu-markdown-to-html exists
+test -f skills/baoyu-markdown-to-html/SKILL.md && echo "found"
+```
+
+| Result | Action |
+|--------|--------|
+| Found | Read its SKILL.md, continue to Step 3 |
+| Multiple skills | AskUserQuestion to choose |
+| Not found | Show installation suggestion |
+
+**When Not Found**:
+
+```
+No markdown-to-html skill found.
+
+Suggested installation:
+https://github.com/JimLiu/baoyu-skills/blob/main/skills/baoyu-markdown-to-html/SKILL.md
+
+Options:
+A) Cancel - install the skill first
+B) Continue - provide HTML file manually
+```
+
+### Step 3: Convert Markdown to HTML
+
+**Skip if**: Input is `.html` file
+
+1. **Ask theme preference** (unless specified in EXTEND.md or CLI):
 
 | Theme | Description |
 |-------|-------------|
 | `default` | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
-| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 (by @brzhang) |
+| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 |
-| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 (by @okooo5km) |
+| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 |
 
-Default: `default`. If user has already specified a theme, skip the question.
+2. **Execute conversion** (using the discovered skill):
 
-**Workflow**:
-
-1. Generate HTML preview and print the full `htmlPath` from JSON output so user can click to preview:
 ```bash
-npx -y bun ${SKILL_DIR}/scripts/md-to-wechat.ts article.md --theme <chosen-theme>
+npx -y bun ${MD_TO_HTML_SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>
 ```
-2. Post to WeChat:
+
+3. **Parse JSON output** to get: `htmlPath`, `title`, `author`, `summary`, `contentImages`
+
+### Step 4: Validate Metadata
+
+Check extracted metadata from Step 3 (or HTML meta tags if direct HTML input).
+
+| Field | If Missing |
+|-------|------------|
+| Title | Prompt: "Enter title, or press Enter to auto-generate from content" |
+| Summary | Prompt: "Enter summary, or press Enter to auto-generate (recommended for SEO)" |
+
+**Auto-Generation Logic**:
+- **Title**: First H1/H2 heading, or first sentence
+- **Summary**: First paragraph, truncated to 120 characters
+
+### Step 5: Select Publishing Method and Configure
+
+**Ask publishing method** (unless specified in EXTEND.md or CLI):
+
+| Method | Speed | Requirements |
+|--------|-------|--------------|
+| `api` (Recommended) | Fast | API credentials |
+| `browser` | Slow | Chrome, login session |
+
+**If API Selected - Check Credentials**:
+
 ```bash
-npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown article.md --theme <chosen-theme>
+# Check project-level
+test -f .baoyu-skills/.env && grep -q "WECHAT_APP_ID" .baoyu-skills/.env && echo "project"
+
+# Check user-level
+test -f "$HOME/.baoyu-skills/.env" && grep -q "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env" && echo "user"
+```
+
+**If Credentials Missing - Guide Setup**:
+
+```
+WeChat API credentials not found.
+
+To obtain credentials:
+1. Visit https://mp.weixin.qq.com
+2. Go to: 开发 → 基本配置
+3. Copy AppID and AppSecret
+
+Where to save?
+A) Project-level: .baoyu-skills/.env (this project only)
+B) User-level: ~/.baoyu-skills/.env (all projects)
+```
+
+After location choice, prompt for values and write to `.env`:
+
+```
+WECHAT_APP_ID=<user_input>
+WECHAT_APP_SECRET=<user_input>
+```
+
+### Step 6: Publish to WeChat
+
+**API method**:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/wechat-api.ts <html_file> [--title <title>] [--summary <summary>]
+```
+
+**Browser method**:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --html <html_file>
+```
+
+### Step 7: Completion Report
+
+**For API method**, include draft management link:
+
+```
+WeChat Publishing Complete!
+
+Input: [type] - [path]
+Method: API
+Theme: [theme name]
+
+Article:
+• Title: [title]
+• Summary: [summary]
+• Images: [N] inline images
+
+Result:
+✓ Draft saved to WeChat Official Account
+• media_id: [media_id]
+
+Next Steps:
+→ Manage drafts: https://mp.weixin.qq.com (登录后进入「内容管理」→「草稿箱」)
+
+Files created:
+[• post-to-wechat/yyyy-MM-dd/slug.md (if plain text)]
+[• slug.html (converted)]
+```
+
+**For Browser method**:
+
+```
+WeChat Publishing Complete!
+
+Input: [type] - [path]
+Method: Browser
+Theme: [theme name]
+
+Article:
+• Title: [title]
+• Summary: [summary]

+Result:
+✓ Draft saved to WeChat Official Account

+  ratio: portrait-3-4
+  grid: single
+
+image_effects:
+  cutout: none
+  stroke: none
+  filter: natural-photo
+
+typography:
+  decorated: none
+  tags: none
+  direction: horizontal
+
+decorations:
+  emphasis: circle-mark | underline | checkmark | cross | star-simple
+  background: lined-paper-white

+- Varying font sizes (large titles, small body, tiny margin notes)
+- CJK optimized
+
+## Content Structure
+
+Three-section layout:
+
+### Top Section
+- Core topic (circled multiple times in red)
+- First section title + 3-4 key points
+- Arrow connections, red underlines
+
+### Middle Section
+- Second section title (red pen box)
+- Numbered steps ①②③
+- Specific methods and supplementary notes
+
+### Bottom Section
+- Third section title (red star)
+- Time points / key metrics
+- Key quotes / core tips (tiny corner notes)
+
+## Best Layout Pairings
+
+| Layout | Compatibility | Use Case |

+| list | ✓✓ | Step checklists, rankings |
+| comparison | ✓ | Comparative analysis |
+| flow | ✓ | Process flows |
+| mindmap | ✓✓ | Mind map notes |
+| quadrant | ✓ | Quadrant analysis |
+
+## Best For
+
+- Study guides, exam notes
