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"

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: Check markdown-to-html skill
- [ ] Step 3: Convert to HTML
- [ ] Step 4: Validate metadata (title, summary, cover)
- [ ] Step 5: Select method and configure credentials
- [ ] Step 6: Publish to WeChat
- [ ] Step 7: 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_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 4
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, then 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: Check Markdown-to-HTML Skill

Skip if: Input is .html file

Skill Discovery:

# Check if baoyu-markdown-to-html exists
test -f skills/baoyu-markdown-to-html/SKILL.md && echo "found"

Result	Action
Found	Read its SKILL.md, continue to Step 3
Multiple skills	AskUserQuestion to choose
Not found	Show installation suggestion

When Not Found:

No markdown-to-html skill found.

Suggested installation:
https://github.com/JimLiu/baoyu-skills/blob/main/skills/baoyu-markdown-to-html/SKILL.md

Options:
A) Cancel - install the skill first
B) Continue - provide HTML file manually

Step 3: Convert Markdown to HTML

Skip if: Input is .html file

1. Ask theme preference (unless specified in EXTEND.md or CLI):

Theme	Description
default	经典主题 - 传统排版，标题居中带底边，二级标题白字彩底
grace	优雅主题 - 文字阴影，圆角卡片，精致引用块
simple	简洁主题 - 现代极简风，不对称圆角，清爽留白

2. Execute conversion (using the discovered skill):

npx -y bun ${MD_TO_HTML_SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>

3. Parse JSON output to get: htmlPath, title, author, summary, contentImages

Step 4: Validate Metadata

Check extracted metadata from Step 3 (or HTML meta tags if direct 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

Cover Image Check (required for article_type=news):

1. Use CLI --cover if provided.
2. Else use frontmatter (featureImage, coverImage, 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 5: 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 6: Publish to WeChat

API method:

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

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:

npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --html <html_file>

Step 7: Completion Report

For API method, include draft management link:

WeChat Publishing Complete!

Input: [type] - [path]
Method: API
Theme: [theme name]

Article:
• Title: [title]
• Summary: [summary]
• Images: [N] inline images
