User Input Tools
When this skill prompts the user, follow this tool-selection rule (priority order):
- Prefer built-in user-input tools exposed by the current agent runtime — e.g.,
AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
- 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.
- 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.
Language
Respond 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.
Script Directory
{baseDir} = this SKILL.md's directory. Resolve ${BUN_X}: prefer bun; else npx -y bun; else suggest brew install oven-sh/bun/bun.

Raw ssh / scp options are intentionally not supported; only the typed keys above are honored. Authentication is SSH key only (no passwords).
Theme options: default, grace, simple, modern. Color presets: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex).
Value priority: CLI args → frontmatter → EXTEND.md (account-level → global) → skill defaults.
Multi-Account Support
EXTEND.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>).
Full details — compatibility rules, per-account keys, credential resolution, per-account Chrome profiles, CLI usage — in references/multi-account.md.
Pre-flight Check (Optional)
Before first use, suggest the environment check (user can skip):
${BUN_X} {baseDir}/scripts/check-permissions.ts
Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.
| Check fails | Fix |
|---|
| Chrome | Install Chrome or set WECHAT_BROWSER_CHROME_PATH |
| Profile dir | Shared profile at baoyu-skills/chrome-profile |
| Bun runtime | brew install oven-sh/bun/bun or npm install -g bun |
| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
| Clipboard copy | Ensure Swift/AppKit (macOS: xcode-select --install) |
| Paste keystroke (Linux) | Install xdotool (X11) or ydotool (Wayland) |
| API credentials | Follow guided setup in Step 2, or set in .baoyu-skills/.env |
Image-Text Posting (图文)
Short posts with multiple images (up to 9):
${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
Details: references/image-text-posting.md.
Article Posting Workflow (文章)
- [ ] Step 0: Load preferences (EXTEND.md)
- [ ] Step 0.5: Resolve account (multi-account only — see references/multi-account.md)
- [ ] 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 (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.
Step 1: Determine Input Type
| Input | Detection | Next |
|---|
| HTML file | Path ends .html, file exists | Skip to Step 3 |
| Markdown file | Path ends .md, file exists | Step 2 |
| Plain text | Not a file path, or file doesn't exist | Save to markdown, then Step 2 |
Plain-text handling:
- Generate slug (first 2-4 meaningful words, kebab-case; translate Chinese to English for the slug).
- Save to
post-to-wechat/YYYY-MM-DD/<slug>.md (create directory if needed).
- Continue as a markdown file.
Step 2: Select Publishing Method and Configure
Ask method unless specified in EXTEND.md or CLI:
| Method | Speed | Requires |
|---|
api (Recommended) | Fast | API credentials (local IP allowlisted) |
browser | Slow | Chrome + logged-in session |
remote-api | Fast | API credentials + an SSH-reachable server whose IP is on the WeChat allowlist |
API selected + missing credentials → run guided setup per references/api-setup.md (writes to .baoyu-skills/.env).
remote-api method: WeChat's "公众号设置 → IP 白名单" often limits API access to one or two fixed IPs. If your local machine's IP is not on that list but a cloud server's is, use remote-api: all markdown rendering, image processing, draft assembly, and HTML rewriting still happen locally, and only the outbound HTTPS calls to api.weixin.qq.com (token, uploadimg, add_material, draft/add) are tunneled through an SSH SOCKS5 dynamic port forward (ssh -N -D) so that WeChat sees the remote server as the source IP. No files are written to the remote host; AppSecret never leaves the local process. Requires only sshd and outbound network on the remote host — no Python, no agent process. See "Remote API Method" below.
Step 3: Resolve Theme/Color and Validate Metadata
- Theme: CLI
--theme → EXTEND.md default_theme → default (first match wins; do NOT ask if resolved).
- Color: CLI
--color → EXTEND.md default_color → omit (theme default applies).
- Validate metadata (frontmatter for markdown, meta tags for HTML):
| Field | Missing → |
|---|
| Title | Ask, or press Enter to auto-generate from content |
| Summary | Frontmatter description → summary → ask or auto-generate |
| Author | CLI --author → frontmatter author → EXTEND.md default_author |
| Source URL | CLI --source-url → frontmatter sourceUrl/contentSourceUrl/content_source_url |
Auto-generation: title = first H1/H2 or first sentence; summary = first paragraph, truncated to 120 chars.
- 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.
Step 4: Publish
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.
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.
API method (accepts .md or .html):
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>] [--source-url <url>] [--no-cite]
Always pass --theme even if it's default. Only pass --color when explicitly set by the user or EXTEND.md.
Remote API method (same script, adds --remote):
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> --remote [--remote-host <host>] [--remote-user <user>] [--remote-port <port>] [--remote-identity-file <path>] [--remote-known-hosts-file <path>] [--remote-strict-host-key-checking yes|no|accept-new] [--remote-connect-timeout <s>] [--remote-proxy-jump <spec>]
Any --remote-* flag implies --remote. CLI values override account-level then global remote_publish_* keys from EXTEND.md. Setting default_publish_method: remote-api also enables remote mode without --remote.
draft/add payload rules:
- 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 required)
- 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
- For
news, optionally include content_source_url (original article URL, shown as "阅读原文" link, max 1KB). Provide via --source-url CLI flag or frontmatter sourceUrl/contentSourceUrl/content_source_url
Browser method (accepts --markdown or --html):
${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>

Troubleshooting
| Issue | Fix |
|---|
| Missing API credentials | Follow guided setup in Step 2 |
| Access token error | Verify credentials valid and not expired |
| Not logged in (browser) | First run opens browser — scan QR to log in. Set TELEGRAM_BOT_TOKEN + TELEGRAM_CHAT_ID to receive the QR image via Telegram |
| Chrome not found | Set WECHAT_BROWSER_CHROME_PATH |
| Title/summary missing | Use auto-generation or provide manually |
| No cover image | Add frontmatter cover or place imgs/cover.png in article directory |
| Wrong comment defaults | Check need_open_comment / only_fans_can_comment in EXTEND.md |
| Paste fails | Check system clipboard permissions |
Remote publish host is required | Set --remote-host or remote_publish_host in EXTEND.md |
SOCKS proxy on 127.0.0.1:… not ready | SSH could not start the tunnel — check key, host, StrictHostKeyChecking, or use --remote-connect-timeout |
ssh exited early during remote publish | Verify the user can ssh non-interactively to the server; raise --remote-connect-timeout if the link is slow |
Remote API call returns errcode 40164 (invalid IP) | The remote server's egress IP is not on WeChat's allowlist; add it in 公众号设置 → IP 白名单 |
