3description: Posts content to WeChat Official Account (微信公众号) via API or Chrome CDP. Supports article posting (文章) with HTML, markdown, or plain text input, and image-text posting (贴图, formerly 图文) with multiple images. Markdown article workflows default to converting ordinary external links into bottom citations for WeChat-friendly output. Use when user mentions "发布公众号", "post to wechat", "微信公众号", or "贴图/图文/文章".

15 
16## User Input Tools
17 
18When this skill prompts the user, follow this tool-selection rule (priority order):
19 
201. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
212. **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.
223. **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.
23 
24Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes.
25 
26## Language
27 
28Respond in the user's language. If they write in Chinese, reply in Chinese; if English, English. Keep technical tokens (paths, flags, field names) in English.
29 
30## Script Directory
31 
32`{baseDir}` = this SKILL.md's directory. Resolve `${BUN_X}`: prefer `bun`; else `npx -y bun`; else suggest `brew install oven-sh/bun/bun`.
33 
34| Script | Purpose |
35|--------|---------|
36| `scripts/wechat-browser.ts` | Image-text posts (图文) |
37| `scripts/wechat-article.ts` | Article posting via browser (文章) |
38| `scripts/wechat-api.ts` | Article posting via API (文章) |
39| `scripts/md-to-wechat.ts` | Markdown → WeChat-ready HTML with image placeholders |
40| `scripts/check-permissions.ts` | Verify environment & permissions |
41 
42## Preferences (EXTEND.md)
43 
44Check these paths in order; first hit wins:
45 
46| Path | Scope |
47|------|-------|
48| `.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | Project |
49| `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | XDG |
50| `$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | User home |
51 
52Found → read, parse, apply. Not found → run first-time setup (`references/config/first-time-setup.md`) before anything else.
53 
54**Minimum keys** (case-insensitive, accept `1/0` or `true/false`):
55 
56| Key | Default | Mapping |
57|-----|---------|---------|
58| `default_author` | empty | Fallback for `author` when CLI/frontmatter not provided |
59| `need_open_comment` | `1` | `articles[].need_open_comment` in `draft/add` |
60| `only_fans_can_comment` | `0` | `articles[].only_fans_can_comment` in `draft/add` |
61 
62**Recommended EXTEND.md**:
63 
64```md
65default_theme: default
66default_color: blue
67default_publish_method: api
68default_author: 宝玉
69need_open_comment: 1
70only_fans_can_comment: 0
71chrome_profile_path: /path/to/chrome/profile
72```
73 
74**Theme options**: default, grace, simple, modern. **Color presets**: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex).
75 
76**Value priority**: CLI args → frontmatter → EXTEND.md (account-level → global) → skill defaults.
77 
78## Multi-Account Support
79 
80EXTEND.md supports an `accounts:` block for managing multiple Official Accounts. With 2+ entries, the workflow inserts a Step 0.5 to prompt for account selection (or auto-selects based on `default: true` or `--account <alias>`).
81 
82Full details — compatibility rules, per-account keys, credential resolution, per-account Chrome profiles, CLI usage — in `references/multi-account.md`.
83 
84## Pre-flight Check (Optional)
85 
86Before first use, suggest the environment check (user can skip):
87 
88```bash
89${BUN_X} {baseDir}/scripts/check-permissions.ts
90```
91 
92Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.
93 
94| Check fails | Fix |
95|-------------|-----|
96| Chrome | Install Chrome or set `WECHAT_BROWSER_CHROME_PATH` |
97| Profile dir | Shared profile at `baoyu-skills/chrome-profile` |
98| Bun runtime | `brew install oven-sh/bun/bun` or `npm install -g bun` |
99| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
100| Clipboard copy | Ensure Swift/AppKit (macOS: `xcode-select --install`) |
101| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |
102| API credentials | Follow guided setup in Step 2, or set in `.baoyu-skills/.env` |
103 
104## Image-Text Posting (图文)
105 
106Short posts with multiple images (up to 9):
107 
108```bash
109${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown article.md --images ./images/
110${BUN_X} {baseDir}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit
111```
112 
113Details: `references/image-text-posting.md`.
114 
115## Article Posting Workflow (文章)
116 
117```
118- [ ] Step 0: Load preferences (EXTEND.md)
119- [ ] Step 0.5: Resolve account (multi-account only — see references/multi-account.md)
120- [ ] Step 1: Determine input type
121- [ ] Step 2: Select method and configure credentials
122- [ ] Step 3: Resolve theme/color and validate metadata
123- [ ] Step 4: Publish to WeChat
124- [ ] Step 5: Report completion
125```
126 
127### Step 0: Load Preferences
128 
129Check and load EXTEND.md (see "Preferences" above). If not found, complete first-time setup before any other questions. Resolve and cache for later steps: `default_theme`, `default_color`, `default_author`, `need_open_comment`, `only_fans_can_comment`.
130 
131### Step 1: Determine Input Type
132 
133| Input | Detection | Next |
134|-------|-----------|------|
135| HTML file | Path ends `.html`, file exists | Skip to Step 3 |
136| Markdown file | Path ends `.md`, file exists | Step 2 |
137| Plain text | Not a file path, or file doesn't exist | Save to markdown, then Step 2 |
138 
139**Plain-text handling**:
140 
1411. Generate slug (first 2-4 meaningful words, kebab-case; translate Chinese to English for the slug).
1422. Save to `post-to-wechat/YYYY-MM-DD/<slug>.md` (create directory if needed).
1433. Continue as a markdown file.
144 
145### Step 2: Select Publishing Method and Configure
146 
147Ask method unless specified in EXTEND.md or CLI:
148 
149| Method | Speed | Requires |
150|--------|-------|----------|
151| `api` (Recommended) | Fast | API credentials |
152| `browser` | Slow | Chrome + logged-in session |
153 
154**API selected + missing credentials** → run guided setup per `references/api-setup.md` (writes to `.baoyu-skills/.env`).
155 
156### Step 3: Resolve Theme/Color and Validate Metadata
157 
1581. **Theme**: CLI `--theme` → EXTEND.md `default_theme` → `default` (first match wins; do NOT ask if resolved).
1592. **Color**: CLI `--color` → EXTEND.md `default_color` → omit (theme default applies).
1603. **Validate metadata** (frontmatter for markdown, meta tags for HTML):
161 
162| Field | Missing → |
163|-------|-----------|
164| Title | Ask, or press Enter to auto-generate from content |
165| Summary | Frontmatter `description` → `summary` → ask or auto-generate |
166| Author | CLI `--author` → frontmatter `author` → EXTEND.md `default_author` |
167 
168Auto-generation: title = first H1/H2 or first sentence; summary = first paragraph, truncated to 120 chars.
169 
1704. **Cover image** (required for API `article_type=news`): CLI `--cover` → frontmatter (`coverImage` / `featureImage` / `cover` / `image`) → `imgs/cover.png` → first inline image → stop and request one if still missing.
171 
172### Step 4: Publish
173 
174**Important — never pre-convert markdown to HTML.** Publishing scripts handle the conversion internally and the two methods render images differently: API renders `<img>` tags for upload, browser uses placeholders for paste-and-replace. Passing a pre-converted HTML breaks one or the other.
175 
176**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 inline links. Existing HTML input is left as-is.
177 
178**API method** (accepts `.md` or `.html`):
179 
180```bash
181${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>] [--no-cite]
182```
183 
184Always pass `--theme` even if it's `default`. Only pass `--color` when explicitly set by the user or EXTEND.md.
185 
186**`draft/add` payload rules**:
187- Endpoint: `POST https://api.weixin.qq.com/cgi-bin/draft/add?access_token=ACCESS_TOKEN`
188- `article_type`: `news` (default) or `newspic`
189- For `news`, include `thumb_media_id` (cover required)
190- Always include `need_open_comment` (default `1`) and `only_fans_can_comment` (default `0`) in the request body, even if the CLI doesn't expose them
191 
192**Browser method** (accepts `--markdown` or `--html`):
193 
194```bash
195${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <markdown_file> --theme <theme> [--color <color>] [--no-cite]
196${BUN_X} {baseDir}/scripts/wechat-article.ts --html <html_file>
197```
198
