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:

ConditionModeBehaviorNo accounts blockSingle-accountCurrent behavior, unchangedaccounts with 1 entrySingle-accountAuto-select, no promptaccounts with 2+ entriesMulti-accountPrompt to select before publishingaccounts with default: trueMulti-accountPre-select default, user can switch

Multi-account EXTEND.md example:

md

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:

text

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}:

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:

bash

# 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:

SourcePathAccount chrome_profile_path in EXTEND.mdUse as-isAuto-generated from alias{shared_profile_parent}/wechat-{alias}/Single-account fallbackShared default profile (current behavior)

CLI --account Argument#

All publishing scripts accept --account <alias>:

bash

${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.

bash

${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:

CheckFixChromeInstall Chrome or set WECHAT_BROWSER_CHROME_PATH env varProfile dirShared profile at baoyu-skills/chrome-profile (see CLAUDE.md Chrome Profile section)Bun runtimebrew install oven-sh/bun/bun (macOS) or npm install -g bunAccessibility (macOS)System Settings → Privacy & Security → Accessibility → enable terminal appClipboard copyEnsure Swift/AppKit available (macOS Xcode CLI tools: xcode-select --install)Paste keystroke (macOS)Same as Accessibility fix abovePaste keystroke (Linux)Install xdotool (X11) or ydotool (Wayland)API credentialsFollow 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):

bash

${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

See references/image-text-posting.md for details.

Article Posting Workflow (文章)#

Copy this checklist and check off items as you complete them:

text

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 TypeDetectionActionHTML filePath ends with .html, file existsSkip to Step 3Markdown filePath ends with .md, file existsContinue to Step 2Plain textNot a file path, or file doesn't existSave 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:

bash

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):

MethodSpeedRequirementsapi (Recommended)FastAPI credentialsbrowserSlowChrome, login session

If API Selected - Check Credentials:

bash

# 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

# 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:

text

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:

text

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):

FieldIf MissingTitlePrompt: "Enter title, or press Enter to auto-generate from content"SummaryPrompt: "Enter summary, or press Enter to auto-generate (recommended for SEO)"AuthorUse 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):

   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).

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):

bash

${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>] [--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):

bash

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

Step 5: Completion Report#

For API method, include draft management link:

text
