Markdown to HTML Converter

Converts Markdown files to beautifully styled HTML with inline CSS, optimized for WeChat Official Account and other platforms.

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent. 2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question. 3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Script Directory

Agent Execution: Determine this SKILL.md directory as {baseDir}. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values.

ScriptPurpose
scripts/main.tsMain entry point

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:

PriorityPathScope
1.baoyu-skills/baoyu-markdown-to-html/EXTEND.mdProject
2${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-markdown-to-html/EXTEND.mdXDG
3$HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.mdUser home

If none found, use defaults.

EXTEND.md supports: default theme, custom CSS variables, code block style, mermaid defaults (mermaid_theme, mermaid_scale, mermaid_background).

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: Determine Theme

Theme resolution order (first match wins): 1. User explicitly specified theme (CLI --theme or conversation) 2. EXTEND.md default_theme (this skill's own EXTEND.md, checked in Step 0) 3. baoyu-post-to-wechat EXTEND.md default_theme (cross-skill fallback) 4. If none found → use AskUserQuestion to confirm

Cross-skill EXTEND.md check (only if this skill's EXTEND.md has no default_theme):

Read $HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md if it exists and look for a default_theme: line. Use the value if present; otherwise fall through.

If theme is resolved from EXTEND.md: Use it directly, do NOT ask the user.

If no default found: use AskUserQuestion to confirm a theme from the Themes table below.

Step 1.5: Determine Citation Mode

Default: Off. Do not ask by default.

Enable only if the user explicitly asks for "微信外链转底部引用", "底部引用", "文末引用", or passes --cite.

Behavior when enabled:

  • Ordinary external links are rendered with numbered superscripts and collected under a final 引用链接 section.
  • https://mp.weixin.qq.com/... links stay as direct links and are not moved to the bottom.
  • Bare links where link text equals URL stay inline.

Step 2: Convert

${BUN_X} {baseDir}/scripts/main.ts <markdown_file> --theme <theme> [--cite]

Step 3: Report Result

Display the output path from JSON result. If backup was created, mention it.

Usage

${BUN_X} {baseDir}/scripts/main.ts <markdown_file> [options]

Options:

OptionDescriptionDefault

Examples:

# Basic conversion (uses default theme, removes first heading)
${BUN_X} {baseDir}/scripts/main.ts article.md

# With specific theme
${BUN_X} {baseDir}/scripts/main.ts article.md --theme grace

# Theme with custom color
${BUN_X} {baseDir}/scripts/main.ts article.md --theme modern --color red

# Enable bottom citations for ordinary external links
${BUN_X} {baseDir}/scripts/main.ts article.md --cite

# Keep the first heading in content
${BUN_X} {baseDir}/scripts/main.ts article.md --keep-title

# Override title
${BUN_X} {baseDir}/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"
    }
  ],
  "mermaidImages": [
    {
      "hash": "a1b2c3d4e5f6",
      "localPath": "/path/to/imgs/.mermaid-cache/mermaid-a1b2c3d4e5f6.png",
      "cached": false
    }
  ]
}

Mermaid rendering: Code blocks fenced as `mermaid are rendered to PNGs via headless Chrome (CDP) and cached at imgs/.mermaid-cache/mermaid-<hash>.png. The cache key includes the code, theme, scale, target width, background, and mermaid version. Add imgs/.mermaid-cache/ to .gitignore if you do not want generated diagrams checked in. Requires Chrome/Chromium/Edge on the system; otherwise the block falls back to <pre class="mermaid">…</pre> and conversion still succeeds.
