Use Bash to check EXTEND.md existence (priority order):

# 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:

Read input markdown file
Check if content contains CJK characters (Chinese/Japanese/Korean)
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):

| 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

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

npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> [options]

Options:

| --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:

# 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:

{
  "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"
    }
  ]
}
