Pre-flight Check (Optional)

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

npx -y bun ${SKILL_DIR}/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	Ensure ~/.local/share/wechat-browser-profile is writable
Bun runtime	curl -fsSL https://bun.sh/install | bash
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):

npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --markdown article.md --images ./images/
npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit

See 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 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:

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:

# Check project-level
test -f .baoyu-skills/.env && grep -q "WECHAT_APP_ID" .baoyu-skills/.env && echo "project"

# Check user-level
test -f "$HOME/.baoyu-skills/.env" && grep -q "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env" && echo "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. Else auto-generate a cover (see below). Only if generation is unavailable or fails, stop and request a cover image before publishing.

Auto-Generate Cover (when no cover is found in steps 1–4):

Generate a cover that matches the article, then pass its path via --cover in Step 4.

1. Derive a visual concept from the article: read the title and opening paragraphs, then distill the core theme/metaphor, mood, and 1–2 key visual elements. Do NOT invent facts beyond the article.
2. Generate the image using the agent's image-generation tool with:
   • Aspect ratio: 16:9 (WeChat cover ratio; 2.35:1 crop is applied by the platform, so keep the main subject centered and avoid important content near edges).
   • Style: clean, modern editorial illustration; cohesive color palette (prefer aligning with EXTEND.md default_color when it maps to a mood, e.g. blue = calm/focus); atmospheric lighting.
   • No text: the image MUST NOT contain any words, letters, or logos (WeChat covers should be clean; text is added by the layout).
   • Filename: cover.png.
3. Place the file in the article directory as <article_dir>/cover.png (copy from the generated asset path if needed).
4. Confirm with the user before publishing: briefly show/describe the generated cover so they can approve or request a regeneration. If the user pre-approved auto-generation (e.g. via CLI/one-shot request), skip the extra confirmation.
5. Use this path as the --cover argument in Step 4.

Note: Cover generation relies on the agent's built-in image-generation capability, not a skill script. If the running environment has no image-generation tool, fall back to asking the user for a cover image.

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).

API method (accepts .md or .html):

npx -y bun ${SKILL_DIR}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>]

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):

npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown <markdown_file> --theme <theme> [--color <color>]
npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --html <html_file>

Step 5: Completion Report

Prerequisites

For API method:

• WeChat Official Account API credentials
• Guided setup in Step 2, or manually set in .baoyu-skills/.env

For Browser method:

• Google Chrome
• First run: log in to WeChat Official Account (session preserved)

Config File Locations (priority order):

1. Environment variables
2. <cwd>/.baoyu-skills/.env
3. ~/.baoyu-skills/.env

Network / Proxy (API method):

• The API script (wechat-api.ts) first tries a direct connection to WeChat. If it fails or times out, it automatically retries once through a proxy.
• Proxy priority: WECHAT_PROXY env → built-in fallback (http://10.158.101.1:8080).
• Override the direct-attempt timeout with WECHAT_DIRECT_TIMEOUT_MS (default 15000).
• Set WECHAT_NO_PROXY_FALLBACK=1 to disable the proxy retry entirely.
• These can also be exported via .baoyu-skills/.env.

Troubleshooting

Issue	Solution
Missing API credentials	Follow guided setup in Step 2
Access token error	Check if API credentials are valid and not expired
Not logged in (browser)	First run opens browser - scan QR to log in
Chrome not found	Set WECHAT_BROWSER_CHROME_PATH env var
Title/summary missing	Use auto-generation or provide manually
No cover image	Skill auto-generates a cover via the agent's image tool; or add frontmatter cover / place imgs/cover.png in article directory. If image generation is unavailable, provide a cover manually
Wrong comment defaults	Check EXTEND.md keys need_open_comment and only_fans_can_comment
Paste fails	Check system clipboard permissions
Unable to connect / connection timeout (API)	No direct route to api.weixin.qq.com. The API script auto-retries through a proxy — set WECHAT_PROXY (or HTTPS_PROXY) to your proxy. Disable auto-retry with WECHAT_NO_PROXY_FALLBACK=1

OpenClaw Migration Notes

• Migration mode: OpenClaw native first
• Preserved directories:
  • scripts: yes
  • references: yes
  • prompts: no
• External dependencies: bun, chrome, external-ai-api, social-platform-access
• Risk level: high
• Environment variables (detected): ACCESS_TOKEN, API, HOME, WECHAT_BROWSER_CHROME_PATH
• Config compatibility: keep original .baoyu-skills/<skill>/EXTEND.md behavior and add OpenClaw-compatible path in runtime wrappers when needed.

OpenClaw Preflight Checks

• Confirm bun is available when script examples use npx -y bun ....
• Confirm Chrome is installed and launchable for CDP/browser automation flows.
• Confirm required API credentials are exported before execution.
• Confirm account session/cookies are valid before posting or scraping operations.

Detected env vars: ACCESS_TOKEN, API, HOME, WECHAT_BROWSER_CHROME_PATH

OpenClaw Failure Fallback

• If runtime dependency is missing, stop execution and return exact install/setup command.
• If API call fails, suggest retry with explicit provider/model flags and validate key scope.
• If browser automation fails, switch to manual/wait mode where available.
• If platform blocks automation, return manual publish/export instructions instead of retry loops.
• For high-risk workflows, require explicit user confirmation before irreversible actions.
