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 <alias> CLI arg:
→ select matching account
elif one account has default: true:
→ pre-select, show: "Using account: <name> (--account to switch)"
else:
→ prompt user:
"Multiple WeChat accounts configured:
1) <name1> (<alias1>)
2) <name2> (<alias2>)
Select account [1-N]:"
Credential Resolution (API Method)
For a selected account with alias {alias}:
app_id / app_secret inline in EXTEND.md account block- Env var
WECHAT_{ALIAS}_APP_ID / WECHAT_{ALIAS}_APP_SECRET (alias uppercased, hyphens → underscores)
.baoyu-skills/.env with prefixed key WECHAT_{ALIAS}_APP_ID~/.baoyu-skills/.env with prefixed key- Fallback to unprefixed
WECHAT_APP_ID / WECHAT_APP_SECRET
.env multi-account example:
WECHAT_BAOYU_APP_ID=your_wechat_app_id
WECHAT_BAOYU_APP_SECRET=your_wechat_app_secret
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 <alias>:
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme default --account ai-tools
${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <file> --theme default --account baoyu
${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown <file> --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 |

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_authorneed_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:
- Generate slug from content (first 2-4 meaningful words, kebab-case)
- Create directory and save file:
mkdir -p "$(pwd)/post-to-wechat/$(date +%Y-%m-%d)"
- 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:
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"
if ((Test-Path .baoyu-skills/.env) -and (Select-String -Quiet -Pattern
