# Post to WeChat Official Account

## 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 `{baseDir}`, then use `{baseDir}/scripts/<name>.ts`. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun.

| 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) |
| `scripts/md-to-wechat.ts` | Markdown → WeChat-ready HTML with image placeholders |
| `scripts/check-permissions.ts` | Verify environment & permissions |

## Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

```bash
# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-post-to-wechat/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "user"
```

```powershell
# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-post-to-wechat/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-skills/baoyu-post-to-wechat/EXTEND.md") { "xdg" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md") { "user" }
```

**EXTEND.md Supports**: Default theme | Default color | 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_color: blue
default_publish_method: api
default_author: 宝玉
need_open_comment: 1
only_fans_can_comment: 0
chrome_profile_path: /path/to/chrome/profile
```

**Theme options**: default, grace, simple, modern

**Color presets**: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex value)

**Value priority**:
1. CLI arguments
2. Frontmatter
3. EXTEND.md (account-level → global-level)
4. Skill defaults

## Multi-Account Support

EXTEND.md supports managing multiple WeChat Official Accounts. When `accounts:` block is present, each account can have its own credentials, Chrome profile, and default settings.

**Compatibility rules**:

| Condition | Mode | Behavior |
|-----------|------|----------|
| No `accounts` block | Single-account | Current behavior, unchanged |
| `accounts` with 1 entry | Single-account | Auto-select, no prompt |
| `accounts` with 2+ entries | Multi-account | Prompt to select before publishing |
| `accounts` with `default: true` | Multi-account | Pre-select default, user can switch |

**Multi-account EXTEND.md example**:

```md
default_theme: default
default_color: blue

accounts:
  - name: 宝玉的技术分享
    alias: baoyu
    default: true
    default_publish_method: api
    default_author: 宝玉
    need_open_comment: 1
    only_fans_can_comment: 0
    app_id: your_wechat_app_id
    app_secret: your_wechat_app_secret
  - name: AI工具集
    alias: ai-tools
    default_publish_method: browser
    default_author: AI工具集
    need_open_comment: 1
    only_fans_can_comment: 0
```

**Per-account keys** (can be set per-account or globally as fallback):
`default_publish_method`, `default_author`, `need_open_comment`, `only_fans_can_comment`, `app_id`, `app_secret`, `chrome_profile_path`

**Global-only keys** (always shared across accounts):
`default_theme`, `default_color`

### Account Selection (Step 0.5)

Insert between Step 0 and Step 1 in the Article Posting Workflow:

```
if no accounts block:
    → single-account mode (current behavior)
elif accounts.length == 1:
    → auto-select the only account
elif --account <alias> CLI arg:
    → select matching account
elif one account has default: true:
    → pre-select, show: "Using account: <name> (--account to switch)"
else:
    → prompt user:
      "Multiple WeChat accounts configured:
       1) <name1> (<alias1>)
       2) <name2> (<alias2>)
       Select account [1-N]:"
```

### Credential Resolution (API Method)

For a selected account with alias `{alias}`:

1. `app_id` / `app_secret` inline in EXTEND.md account block
2. Env var `WECHAT_{ALIAS}_APP_ID` / `WECHAT_{ALIAS}_APP_SECRET` (alias uppercased, hyphens → underscores)
3. `.baoyu-skills/.env` with prefixed key `WECHAT_{ALIAS}_APP_ID`
4. `~/.baoyu-skills/.env` with prefixed key
5. Fallback to unprefixed `WECHAT_APP_ID` / `WECHAT_APP_SECRET`

**.env multi-account example**:

```bash
# Account: baoyu
WECHAT_BAOYU_APP_ID=your_wechat_app_id
WECHAT_BAOYU_APP_SECRET=your_wechat_app_secret

# Account: ai-tools
WECHAT_AI_TOOLS_APP_ID=your_ai_tools_wechat_app_id
WECHAT_AI_TOOLS_APP_SECRET=your_ai_tools_wechat_app_secret
```

### Chrome Profile (Browser Method)

Each account uses an isolated Chrome profile for independent login sessions:

| Source | Path |
|--------|------|
| Account `chrome_profile_path` in EXTEND.md | Use as-is |
| Auto-generated from alias | `{shared_profile_parent}/wechat-{alias}/` |
| Single-account fallback | Shared default profile (current behavior) |

### CLI `--account` Argument

All publishing scripts accept `--account <alias>`:

```bash
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme default --account ai-tools
${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <file> --theme default --account baoyu
${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown <file> --images ./photos/ --account baoyu
```

## Pre-flight Check (Optional)

Before first use, suggest running the environment check. User can skip if they prefer.

```bash
${BUN_X} {baseDir}/scripts/check-permissions.ts
```

Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.

**If any check fails**, provide fix guidance per item:

| Check | Fix |
|-------|-----|
| Chrome | Install Chrome or set `WECHAT_BROWSER_CHROME_PATH` env var |
| Profile dir | Shared profile at `baoyu-skills/chrome-profile` (see CLAUDE.md Chrome Profile section) |
| Bun runtime | `brew install oven-sh/bun/bun` (macOS) or `npm install -g bun` |
| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
| Clipboard copy | Ensure Swift/AppKit available (macOS Xcode CLI tools: `xcode-select --install`) |
| Paste keystroke (macOS) | Same as Accessibility fix above |
| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |
| API credentials | Follow guided setup in Step 2, or manually set in `.baoyu-skills/.env` |

## Image-Text Posting (图文)

For short posts with multiple images (up to 9):

```bash
${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown article.md --images ./images/
${BUN_X} {baseDir}/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 0.5: Resolve account (multi-account only)
- [ ] Step 1: Determine input type
- [ ] Step 2: Select method and configure credentials
- [ ] Step 3: Resolve theme/color and validate metadata
- [ ] Step 4: Publish to WeChat
- [ ] Step 5: 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_theme` (default `default`)
- `default_color` (omit if not set — theme default applies)
- `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 3 |
| 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, continue to 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: Select Publishing Method and Configure

**Ask publishing method** (unless specified in EXTEND.md or CLI):

| Method | Speed | Requirements |
|--------|-------|--------------|
| `api` (Recommended) | Fast | API credentials |
| `browser` | Slow | Chrome, login session |

**If API Selected - Check Credentials**:

```bash
# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/.env && grep -q "WECHAT_APP_ID" .baoyu-skills/.env && echo "project"
test -f "$HOME/.baoyu-skills/.env" && grep -q "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env" && echo "user"
```

```powershell
# PowerShell (Windows)
if ((Test-Path .baoyu-skills/.env) -and (Select-String -Quiet -Pattern "WECHAT_APP_ID" .baoyu-skills/.env)) { "project" }
if ((Test-Path "$HOME/.baoyu-skills/.env") -and (Select-String -Quiet -Pattern "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env")) { "user" }
```

**If Credentials Missing - Guide Setup**:

```
WeChat API credentials not found.

To obtain credentials:
1. Visit https://mp.weixin.qq.com
2. Go to: 开发 → 基本配置
3. Copy AppID and AppSecret

Where to save?
A) Project-level: .baoyu-skills/.env (this project only)
B) User-level: ~/.baoyu-skills/.env (all projects)
```

After location choice, prompt for values and write to `.env`:

```
WECHAT_APP_ID=<user_input>
WECHAT_APP_SECRET=<user_input>
```

### Step 3: Resolve Theme/Color and Validate Metadata

1. **Resolve theme** (first match wins, do NOT ask user if resolved):
   - CLI `--theme` argument
   - EXTEND.md `default_theme` (loaded in Step 0)
   - Fallback: `default`

2. **Resolve color** (first match wins):
   - CLI `--color` argument
   - EXTEND.md `default_color` (loaded in Step 0)
   - Omit if not set (theme default applies)

3. **Validate metadata** from frontmatter (markdown) or HTML meta tags (HTML input):

| Field | If Missing |
|-------|------------|
| Title | Prompt: "Enter title, or press Enter to auto-generate from content" |
| Summary | Prompt: "Enter summary, or press Enter to auto-generate (recommended for SEO)" |
| Author | Use fallback chain: CLI `--author` → frontmatter `author` → EXTEND.md `default_author` |

**Auto-Generation Logic**:
- **Title**: First H1/H2 heading, or first sentence
- **Summary**: First paragraph, truncated to 120 characters

4. **Cover Image Check** (required for API `article_type=news`):
   1. Use CLI `--cover` if provided.
   2. Else use frontmatter (`coverImage`, `featureImage`, `cover`, `image`).
   3. Else check article directory default path: `imgs/cover.png`.
   4. Else fallback to first inline content image.
   5. If still missing, stop and request a cover image before publishing.

### Step 4: Publish to WeChat

**CRITICAL**: Publishing scripts handle markdown conversion internally. Do NOT pre-convert markdown to HTML — pass the original markdown file directly. This ensures the API method renders images as `<img>` tags (for API upload) while the browser method uses placeholders (for paste-and-replace workflow).

**Markdown citation default**:
- For markdown input, ordinary external links are converted to bottom citations by default.
- Use `--no-cite` only if the user explicitly wants to keep ordinary external links inline.
- Existing HTML input is left as-is; no extra citation conversion is applied.

**API method** (accepts `.md` or `.html`):

```bash
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>] [--no-cite]
```

**CRITICAL**: Always include `--theme` parameter. Never omit it, even if using `default`. Only include `--color` if explicitly set by user or EXTEND.md.

**`draft/add` payload rules**:
- Use endpoint: `POST https://api.weixin.qq.com/cgi-bin/draft/add?access_token=ACCESS_TOKEN`
- `article_type`: `news` (default) or `newspic`
- For `news`, include `thumb_media_id` (cover is required)
- Always resolve and send:
  - `need_open_comment` (default `1`)
  - `only_fans_can_comment` (default `0`)
- `author` resolution: CLI `--author` → frontmatter `author` → EXTEND.md `default_author`

If script parameters do not expose the two comment fields, still ensure final API request body includes resolved values.

**Browser method** (accepts `--markdown` or `--html`):

```bash
${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <markdown_file> --theme <theme> [--color <color>] [--no-cite]
${BUN_X} {baseDir}/scripts/wechat-article.ts --html <html_file>
```

### Step 5: Completion Report

**For API method**, include draft management link:

```
WeChat Publishing Complete!

Input: [type] - [path]
Method: API
Theme: [theme name] [color if set]

Article:
• Title: [title]
• Summary: [summary]
• Images: [N] inline images
• Comments: [open/closed], [fans-only/all users]

Result:
✓ Draft saved to WeChat Official Account

Files created:
[• post-to-wechat/yyyy-MM-dd/slug.md (if plain text)]
[• slug.html (converted)]
```

**For Browser method**:

```
