Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .baoyu-skills/baoyu-post-to-wechat/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "user"

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

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):

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):

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. If still missing, stop and request a cover image before publishing.

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>
