Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-post-to-wechat/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && echo "user"

# PowerShell (Windows)

4. Skill defaults

Multi-Account Support

EXTEND.md supports managing multiple WeChat Official Accounts. When accounts: block is present, each account can have its own credentials, Chrome profile, and default settings.

Compatibility rules:

| Condition | Mode | Behavior | |-----------|------|----------| | No accounts block | Single-account | Current behavior, unchanged | | accounts with 1 entry | Single-account | Auto-select, no prompt | | accounts with 2+ entries | Multi-account | Prompt to select before publishing | | accounts with default: true | Multi-account | Pre-select default, user can switch |

Multi-account EXTEND.md example:

default_theme: default
default_color: blue

accounts:
  - name: 宝玉的技术分享
    alias: baoyu
    default: true
    default_publish_method: api
    default_author: 宝玉
    need_open_comment: 1
    only_fans_can_comment: 0
    app_id: your_wechat_app_id
    app_secret: your_wechat_app_secret
  - name: AI工具集
    alias: ai-tools
    default_publish_method: browser
    default_author: AI工具集
    need_open_comment: 1
    only_fans_can_comment: 0

Per-account keys (can be set per-account or globally as fallback): default_publish_method, default_author, need_open_comment, only_fans_can_comment, app_id, app_secret, chrome_profile_path

Global-only keys (always shared across accounts): default_theme, default_color

Account Selection (Step 0.5)

Insert between Step 0 and Step 1 in the Article Posting Workflow:

if no accounts block:
    → single-account mode (current behavior)
elif accounts.length == 1:
    → auto-select the only account
elif --account  CLI arg:
    → select matching account
elif one account has default: true:
    → pre-select, show: "Using account:  (--account to switch)"
else:
    → prompt user:
      "Multiple WeChat accounts configured:
       1)  ()
       2)  ()
       Select account [1-N]:"

Credential Resolution (API Method)

For a selected account with alias {alias}:

1. app_id / app_secret inline in EXTEND.md account block
2. Env var WECHAT_{ALIAS}_APP_ID / WECHAT_{ALIAS}_APP_SECRET (alias uppercased, hyphens → underscores)
3. .baoyu-skills/.env with prefixed key WECHAT_{ALIAS}_APP_ID
4. ~/.baoyu-skills/.env with prefixed key
5. Fallback to unprefixed WECHAT_APP_ID / WECHAT_APP_SECRET

.env multi-account example:

# Account: baoyu
WECHAT_BAOYU_APP_ID=your_wechat_app_id
WECHAT_BAOYU_APP_SECRET=your_wechat_app_secret

# Account: ai-tools
WECHAT_AI_TOOLS_APP_ID=your_ai_tools_wechat_app_id
WECHAT_AI_TOOLS_APP_SECRET=your_ai_tools_wechat_app_secret

Chrome Profile (Browser Method)

Each account uses an isolated Chrome profile for independent login sessions:

| Source | Path | |--------|------| | Account chrome_profile_path in EXTEND.md | Use as-is | | Auto-generated from alias | {shared_profile_parent}/wechat-{alias}/ | | Single-account fallback | Shared default profile (current behavior) |

CLI --account Argument

All publishing scripts accept --account :

${BUN_X} {baseDir}/scripts/wechat-api.ts  --theme default --account ai-tools
${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown  --theme default --account baoyu
${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown  --images ./photos/ --account baoyu

Pre-flight Check (Optional)

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

${BUN_X} {baseDir}/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 | Shared profile at baoyu-skills/chrome-profile (see CLAUDE.md Chrome Profile section) | | Bun runtime | brew install oven-sh/bun/bun (macOS) or npm install -g bun | | 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):

${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

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 0.5: Resolve account (multi-account only)
- [ ] 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

1. 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:

# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/.env && grep -q "WECHAT_APP_ID" .baoyu-skills/.env && echo "project"
test -f "$HOME/.baoyu-skills/.env" && grep -q "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env" && echo "user"

# PowerShell (Windows)
if ((Test-Path .baoyu-skills/.env) -and (Select-String -Quiet -Pattern "WECHAT_APP_ID" .baoyu-skills/.env)) { "project" }
if ((Test-Path "$HOME/.baoyu-skills/.env") -and (Select-String -Quiet -Pattern "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env")) { "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=
WECHAT_APP_SECRET=

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

1. Resolve color (first match wins):

• CLI --color argument
• EXTEND.md default_color (loaded in Step 0)
• Omit if not set (theme default applies)

1. 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

1. Cover Image Check (required for API article_type=news):
2. Use CLI --cover if provided.
3. Else use frontmatter (coverImage, featureImage, cover, image).
4. Else check article directory default path: imgs/cover.png.
5. Else fallback to first inline content image.
6. 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 `` tags (for API upload) while the browser method uses placeholders (for paste-and-replace workflow).

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 ordinary external links inline.
• Existing HTML input is left as-is; no extra citation conversion is applied.

API method (accepts .md or .html):

${BUN_X} {baseDir}/scripts/wechat-api.ts  --theme  [--color ] [--title ] [--summary ] [--author ] [--cover ] [--no-cite]

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):

${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown  --theme  [--color ] [--no-cite]
${BUN_X} {baseDir}/scripts/wechat-article.ts --html 

Step 5: Completion Report

For API method, include draft management link:
