# 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.

| Script | Purpose |
|--------|---------|
| `scripts/main.ts` | Main entry point |

## Preferences (EXTEND.md)

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

| Priority | Path | Scope |
|----------|------|-------|
| 1 | `.baoyu-skills/baoyu-markdown-to-html/EXTEND.md` | Project |
| 2 | `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-markdown-to-html/EXTEND.md` | XDG |
| 3 | `$HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.md` | User 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](#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

```bash
${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

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

**Options:**

| Option | Description | Default |
|--------|-------------|---------|
| `--theme <name>` | Theme name (default, grace, simple, modern) | default |
| `--color <name\|hex>` | Primary color: preset name or hex value | theme default |
| `--font-family <name>` | Font: sans, serif, serif-cjk, mono, or CSS value | theme default |
| `--font-size <N>` | Font size: 14px, 15px, 16px, 17px, 18px | 16px |
| `--title <title>` | Override title from frontmatter | |
| `--cite` | Convert external links to bottom citations, append `引用链接` section | false (off) |
| `--keep-title` | Keep the first heading in content | false (removed) |
| `--mermaid-theme <name>` | Mermaid theme: `default`, `forest`, `dark`, `neutral`, `base` | default |
| `--mermaid-scale <N>` | Mermaid render scale (positive number ≤ 4) | 2 |
| `--mermaid-width <N>` | Mermaid target display width in CSS px; PNG is rendered at `width × scale` pixels when the diagram is narrower than this | 860 |
| `--mermaid-bg <value>` | Mermaid background: `white`, `transparent`, or `#hex` | white |
| `--no-mermaid` | Skip Mermaid PNG rendering; emit `<pre class="mermaid">` fallback | false |
| `--help` | Show help | |

**Color Presets:**

| Name | Hex | Label |
|------|-----|-------|
| blue | #0F4C81 | Classic Blue |
| green | #009874 | Emerald Green |
| vermilion | #FA5151 | Vibrant
