Multi-Account Support

Details for managing multiple WeChat Official Accounts through one EXTEND.md. SKILL.md only covers single-account flow and the selection prompt — read this file when the user has an accounts: block, asks to publish to a specific account, or needs per-account credentials.

Compatibility

Condition	Mode	Behavior
No accounts block	Single-account	Original behavior, no changes
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

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 vs Global Keys

Per-account (also accepted globally as fallback): default_publish_method, default_author, need_open_comment, only_fans_can_comment, app_id, app_secret, chrome_profile_path.

Global-only (always shared): default_theme, default_color.

Account Selection (Step 0.5)

Insert between Step 0 (Load EXTEND.md) and Step 1 (Determine input type):

if no accounts block:
    → single-account mode (original 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, display: "Using account: <name> (--account to switch)"
else:
    → prompt user to choose from the list

Credential Resolution (API Method)

For the selected account with alias {alias}, try in this order (first hit wins):

1. app_id / app_secret inline in the EXTEND.md account block
2. Env vars WECHAT_{ALIAS}_APP_ID / WECHAT_{ALIAS}_APP_SECRET (alias uppercased, hyphens → underscores)
3. .baoyu-skills/.env with the prefixed key WECHAT_{ALIAS}_APP_ID
4. ~/.baoyu-skills/.env with the 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 so logins don't collide.

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

CLI --account Flag

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
