## Preferences (EXTEND.md)

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

```bash
# Check project-level first
test -f .baoyu-skills/baoyu-post-to-wechat/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "user"
```

## Usage

### Image-Text (图文)

```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)

Before posting, ask user to choose a theme using AskUserQuestion:

| 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) |

Default: `default`. If user has already specified a theme, skip the question.

**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>
```
2. Post to WeChat:
```bash
npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown article.md --theme <chosen-theme>
```
