User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. 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.
3. 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.

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 these paths in order; first hit wins:

Path	Scope
.baoyu-skills/baoyu-post-to-wechat/EXTEND.md	Project
${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-wechat/EXTEND.md	XDG
$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md	User home

Found → read, parse, apply. Not found → run first-time setup (references/config/first-time-setup.md) before anything else.

Minimum 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
only_fans_can_comment	0	articles[].only_fans_can_comment in draft/add

Recommended EXTEND.md:

default_theme: default
default_color: blue
default_publish_method: browser
default_author: 宝玉
need_open_comment: 1
only_fans_can_comment: 0
chrome_profile_path: /path/to/chrome/profile

# Remote API publishing (optional) — only set if WeChat's IP allowlist
# excludes your local machine. See "Remote API Method" below.
# remote_publish_host: server.example.com
# remote_publish_user: deploy
# remote_publish_port: 22
# remote_publish_identity_file: ~/.ssh/id_ed25519
# remote_publish_known_hosts_file: ~/.ssh/known_hosts

# remote_publish_connect_timeout: 10
# remote_publish_proxy_jump: bastion.example.com

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:

1. Generate slug (first 2-4 meaningful words, kebab-case; translate Chinese to English for the slug).
2. Save to post-to-wechat/YYYY-MM-DD/<slug>.md (create directory if needed).
3. 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

1. Theme: CLI --theme → EXTEND.md default_theme → default (first match wins; do NOT ask if resolved).
2. Color: CLI --color → EXTEND.md default_color → omit (theme default applies).
3. 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.

4. 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
