## Language

**Match user's language**: Respond in the same language the user uses. If user writes in Chinese, respond in Chinese. If user writes in English, respond in English.

## Script Directory

**Agent Execution**: Determine this SKILL.md directory as `SKILL_DIR`, then use `${SKILL_DIR}/scripts/<name>.ts`.

| Script | Purpose |
|--------|---------|
| `scripts/wechat-browser.ts` | Image-text posts (图文) |
| `scripts/wechat-article.ts` | Article posting via browser (文章) |
| `scripts/wechat-api.ts` | Article posting via API (文章) |

## 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"
```

**EXTEND.md Supports**: Default theme | Default publishing method (api/browser) | Default author | Default open-comment switch | Default fans-only-comment switch | Chrome profile path

First-time setup: [references/config/first-time-setup.md](references/config/first-time-setup.md)

**Minimum supported keys** (case-insensitive, accept `1/0` or `true/false`):

| Key | Default | Mapping |
|-----|---------|---------|
| `default_author` | empty | Fallback for `author` when CLI/frontmatter not provided |
| `need_open_comment` | `1` | `articles[].need_open_comment` in `draft/add` request |
| `only_fans_can_comment` | `0` | `articles[].only_fans_can_comment` in `draft/add` request |

**Recommended EXTEND.md example**:

```md
default_theme: default
default_publish_method: api
default_author: 宝玉
need_open_comment: 1
only_fans_can_comment: 0
chrome_profile_path: /path/to/chrome/profile
```

**Value priority**:
1. CLI arguments
2. Frontmatter
3. EXTEND.md
4. Skill defaults

## Image-Text Posting (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
```

See [references/image-text-posting.md](references/image-text-posting.md) for details.

## 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, cover)
- [ ] 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).

**CRITICAL**: If not found, complete first-time setup BEFORE any other steps or questions.

Resolve and store these defaults for later steps:
- `default_author`
- `need_open_comment` (default `1`)
- `only_fans_can_comment` (default `0`)

### 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 |
| `simple` |
