Baoyu Post To Wechat

jimliu/baoyu-post-to-wechat

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".

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.

| 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_strict_host_key_checking: accept-new
# 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:

  • 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_themedefault (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 descriptionsummary → 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 |

How to use it

Copy the folder

Take jimliu/baoyu-post-to-wechat from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm, npx, brew. Without those the skill loads but fails at the first command.
