name: baoyu-post-to-wechat
description: Posts content to WeChat Official Account (微信公众号) via API or Chrome CDP. Supports article posting (文章) with HTML, markdown, or plain text input, and image-text posting (贴图, formerly 图文) with multiple images. Markdown article workflows default to converting ordinary external links into bottom citations for WeChat-friendly output. Use when user mentions "发布公众号", "post to wechat", "微信公众号", or "贴图/图文/文章".

# Post to WeChat Official Account
## User Input Tools
When this skill prompts the user, follow this tool-selection rule (priority order):
1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
2. **Fallback**: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
3. **Batching**: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.
Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes.
## Language
Respond in the user's language. If they write in Chinese, reply in Chinese; if English, English. Keep technical tokens (paths, flags, field names) in English.
## Script Directory
`{baseDir}` = this SKILL.md's directory. Resolve `${BUN_X}`: prefer `bun`; else `npx -y bun`; else suggest `brew install oven-sh/bun/bun`.
| Script | Purpose |
|--------|---------|
| `scripts/wechat-browser.ts` | Image-text posts (图文) |
| `scripts/wechat-article.ts` | Article posting via browser (文章) |
| `scripts/wechat-api.ts` | Article posting via API (文章) |
| `scripts/md-to-wechat.ts` | Markdown → WeChat-ready HTML with image placeholders |
| `scripts/check-permissions.ts` | Verify environment & permissions |
## Preferences (EXTEND.md)
Check these paths in order; first hit wins:
| Path | Scope |
|------|-------|
| `.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | Project |
| `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | XDG |
| `$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | User home |
Found → read, parse, apply. Not found → run first-time setup (`references/config/first-time-setup.md`) before anything else.
**Minimum keys** (case-insensitive, accept `1/0` or `true/false`):
| Key | Default | Mapping |
|-----|---------|---------|
| `default_author` | empty | Fallback for `author` when CLI/frontmatter not provided |
| `need_open_comment` | `1` | `articles[].need_open_comment` in `draft/add` |
| `only_fans_can_comment` | `0` | `articles[].only_fans_can_comment` in `draft/add` |
**Recommended EXTEND.md**:
```md
default_theme: default
default_color: blue
default_publish_method: browser
default_author: 宝玉
need_open_comment: 1
only_fans_can_comment: 0
chrome_profile_path: /path/to/chrome/profile
# Remote API publishing (optional) — only set if WeChat's IP allowlist
# excludes your local machine. See "Remote API Method" below.
# remote_publish_host: server.example.com
# remote_publish_user: deploy
# remote_publish_port: 22
# remote_publish_identity_file: ~/.ssh/id_ed25519
# remote_publish_known_hosts_file: ~/.ssh/known_hosts
# remote_publish_strict_host_key_checking: accept-new
# remote_publish_connect_timeout: 10
# remote_publish_proxy_jump: bastion.example.com
```
Raw `ssh` / `scp` options are intentionally not supported; only the typed keys above are honored. Authentication is SSH key only (no passwords).
**Theme options**: default, grace, simple, modern. **Color presets**: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex).
**Value priority**: CLI args → frontmatter → EXTEND.md (account-level → global) → skill defaults.
## Multi-Account Support
EXTEND.md supports an `accounts:` block for managing multiple Official Accounts. With 2+ entries, the workflow inserts a Step 0.5 to prompt for account selection (or auto-selects based on `default: true` or `--account <alias>`).
Full details — compatibility rules, per-account keys, credential resolution, per-account Chrome profiles, CLI usage — in `references/multi-account.md`.
## Pre-flight Check (Optional)
Before first use, suggest the environment check (user can skip):
```bash
${BUN_X} {baseDir}/scripts/check-permissions.ts
```
Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.
| Check fails | Fix |
|-------------|-----|
| Chrome | Install Chrome or set `WECHAT_BROWSER_CHROME_PATH` |
| Profile dir | Shared profile at `baoyu-skills/chrome-profile` |
| Bun runtime | `brew install oven-sh/bun/bun` or `npm install -g bun` |
| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
| Clipboard copy | Ensure Swift/AppKit (macOS: `xcode-select --install`) |
| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |
| API credentials | Follow guided setup in Step 2, or set in `.baoyu-skills/.env` |
## Image-Text Posting (图文)
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
```
Details: `references/image-text-posting.md`.
## Article Posting Workflow (文章)
```
- [ ] Step 0: Load preferences (EXTEND.md)
- [ ] Step 0.5: Resolve account (multi-account only — see references/multi-account.md)
- [ ] 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 (see "Preferences" above). If not found, complete first-time setup before any other questions. Resolve and cache for later steps: `default_theme`, `default_color`, `default_author`, `need_open_comment`, `only_fans_can_comment`.
### Step 1: Determine Input Type
| Input | Detection | Next |
|-------|-----------|------|
| HTML file | Path ends `.html`, file exists | Skip to Step 3 |
| Markdown file | Path ends `.md`, file exists | 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 (first 2-4 meaningful words, kebab-case; translate Chinese to English for the slug).
2. Save to `post-to-wechat/YYYY-MM-DD/<slug>.md` (create directory if needed).
3. Continue as a markdown file.
### Step 2: Select Publishing Method and Configure
Ask method unless specified in EXTEND.md or CLI:
| Method | Speed | Requires |
|--------|-------|----------|
| `api` (Recommended) | Fast | API credentials (local IP allowlisted) |
| `browser` | Slow | Chrome + logged-in session |
| `remote-api` | Fast | API credentials + an SSH-reachable server whose IP is on the WeChat allowlist |
**API selected + missing credentials** → run guided setup per `references/api-setup.md` (writes to `.baoyu-skills/.env`).
**`remote-api` method**: WeChat's "公众号设置 → IP 白名单" often limits API access to one or two fixed IPs. If your local machine's IP is not on that list but a cloud server's is, use `remote-api`: all markdown rendering, image processing, draft assembly, and HTML rewriting still happen locally, and only the outbound HTTPS calls to `api.weixin.qq.com` (token, uploadimg, add_material, draft/add) are tunneled through an SSH SOCKS5 dynamic port forward (`ssh -N -D`) so that WeChat sees the remote server as the source IP. No files are written to the remote host; `AppSecret` never leaves the local process. Requires only `sshd` and outbound network on the remote host — no Python, no agent process. See "Remote API Method" below.
### Step 3: Resolve Theme/Color and Validate Metadata
1. **Theme**: CLI `--theme` → EXTEND.md `default_theme` → `default` (first match wins; do NOT ask if resolved).
2. **Color**: CLI `--color` → EXTEND.md `default_color` → omit (theme default applies).
3. **Validate metadata** (frontmatter for markdown, meta tags for HTML):
| Field | Missing → |
|-------|-----------|
| Title | Ask, or press Enter to auto-generate from content |
| Summary | Frontmatter `description` → `summary` → ask or auto-generate |
| Author | CLI `--author` → frontmatter `author` → EXTEND.md `default_author` |
| Source URL | CLI `--source-url` → frontmatter `sourceUrl`/`contentSourceUrl`/`content_source_url` |
Auto-generation: title = first H1/H2 or first sentence; summary = first paragraph, truncated to 120 chars.
4. **Cover image** (required for API `article_type=news`): CLI `--cover` → frontmatter (`coverImage` / `featureImage` / `cover` / `image`) → `imgs/cover.png` → first inline image → stop and request one if still missing.
### Step 4: Publish
**Important — never pre-convert markdown to HTML.** Publishing scripts handle the conversion internally and the two methods render images differently: API renders `<img>` tags for upload, browser uses placeholders for paste-and-replace. Passing a pre-converted HTML breaks one or the other.
**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 inline links. Existing HTML input is left as-is.
**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>] [--source-url <url>] [--no-cite]
```
Always pass `--theme` even if it's `default`. Only pass `--color` when explicitly set by the user or EXTEND.md.
**Remote API method** (same script, adds `--remote`):
```bash
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> --remote [--remote-host <host>] [--remote-user <user>] [--remote-port <port>] [--remote-identity-file <path>] [--remote-known-hosts-file <path>] [--remote-strict-host-key-checking yes|no|accept-new] [--remote-connect-timeout <s>] [--remote-proxy-jump <spec>]
```
Any `--remote-*` flag implies `--remote`. CLI values override account-level then global `remote_publish_*` keys from EXTEND.md. Setting `default_publish_method: remote-api` also enables remote mode without `--remote`.
**`draft/add` payload rules**:
- 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 required)
- Always include `need_open_comment` (default `1`) and `only_fans_can_comment` (default `0`) in the request body, even if the CLI doesn't expose them
- For `news`, optionally include `content_source_url` (original article URL, shown as "阅读原文" link, max 1KB). Provide via `--source-url` CLI flag or frontmatter `sourceUrl`/`contentSourceUrl`/`content_source_url`
**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>
```

| Speed | Medium | Fast | Fast | Slow |
## Troubleshooting
| Issue | Fix |
|-------|-----|
| Missing API credentials | Follow guided setup in Step 2 |
| Access token error | Verify credentials valid and not expired |
| Not logged in (browser) | First run opens browser — scan QR to log in. Set `TELEGRAM_BOT_TOKEN` + `TELEGRAM_CHAT_ID` to receive the QR image via Telegram |
| Chrome not found | Set `WECHAT_BROWSER_CHROME_PATH` |
| Title/summary missing | Use auto-generation or provide manually |
| No cover image | Add frontmatter cover or place `imgs/cover.png` in article directory |
| Wrong comment defaults | Check `need_open_comment` / `only_fans_can_comment` in EXTEND.md |
| Paste fails | Check system clipboard permissions |
| `Remote publish host is required` | Set `--remote-host` or `remote_publish_host` in EXTEND.md |
| `SOCKS proxy on 127.0.0.1:… not ready` | SSH could not start the tunnel — check key, host, `StrictHostKeyChecking`, or use `--remote-connect-timeout` |
| `ssh exited early` during remote publish | Verify the user can `ssh` non-interactively to the server; raise `--remote-connect-timeout` if the link is slow |
| Remote API call returns `errcode 40164` (invalid IP) | The remote server's egress IP is not on WeChat's allowlist; add it in 公众号设置 → IP 白名单 |

# API Credential Setup
Guided setup when `WECHAT_APP_ID` / `WECHAT_APP_SECRET` are missing. Invoked by Step 2 of the article-posting workflow.
## Detection
Look for the credentials in this order:
1. Env vars `WECHAT_APP_ID` / `WECHAT_APP_SECRET`
2. `<cwd>/.baoyu-skills/.env` with `WECHAT_APP_ID=...`
3. `$HOME/.baoyu-skills/.env` with `WECHAT_APP_ID=...`
If none are present, run the guided setup below.
## Guided Setup
Show this message to the user and ask where to save:
```
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 they choose a location, collect the values (prefer a user-input tool, fall back to a numbered prompt per the User Input Tools rule in SKILL.md) and append:
```
WECHAT_APP_ID=<user_input>
WECHAT_APP_SECRET=<user_input>
```
## Multi-Account Variant
If the user has multiple accounts configured (`accounts:` block in EXTEND.md), use prefixed keys instead — see `multi-account.md` → "Credential Resolution".

# Article Posting (文章发表)
Post markdown articles to WeChat Official Account with full formatting support.
## Usage
```bash
# Post markdown article
${BUN_X} ./scripts/wechat-article.ts --markdown article.md
# With theme
${BUN_X} ./scripts/wechat-article.ts --markdown article.md --theme grace
# Disable bottom citations for ordinary external links
${BUN_X} ./scripts/wechat-article.ts --markdown article.md --no-cite
# With explicit options
${BUN_X} ./scripts/wechat-article.ts --markdown article.md --author "作者名" --summary "摘要"
```
## Parameters
| Parameter | Description |
|-----------|-------------|
| `--markdown <path>` | Markdown file to convert and post |
| `--theme <name>` | Theme: default, grace, simple, modern |
| `--no-cite` | Keep ordinary external links inline instead of converting them to bottom citations |
| `--title <text>` | Override title (auto-extracted from markdown) |
| `--author <name>` | Author name |
| `--summary <text>` | Article summary |
| `--html <path>` | Pre-rendered HTML file (alternative to markdown) |
| `--profile <dir>` | Chrome profile directory |
## Markdown Format
```markdown
---
title: Article Title
author: Author Name
---

Regular paragraph with **bold** and *italic*.
## Section Header
![Image description](./image.png)
- List item 1
- List item 2
> Blockquote text
[Link text](https://example.com)
```
Markdown mode converts ordinary external links into bottom citations by default for WeChat-friendly output. Use `--no-cite` to disable that behavior.
## Image Handling
1. **Parse**: Images in markdown are replaced with `WECHATIMGPH_N`
2. **Render**: HTML is generated with placeholders in text
3. **Paste**: HTML content is pasted into WeChat editor
4. **Replace**: For each placeholder:
- Find and select the placeholder text
- Scroll into view
- Press Backspace to delete the placeholder
- Paste the image from clipboard
## Scripts
| Script | Purpose |
|--------|---------|
| `wechat-article.ts` | Main article publishing script |
| `md-to-wechat.ts` | Markdown to HTML with placeholders |
| `md/render.ts` | Markdown rendering with themes |
## Example Session
```
User: /post-to-wechat --markdown ./article.md
Claude:
1. Parses markdown, finds 5 images
2. Generates HTML with placeholders
3. Opens Chrome, navigates to WeChat editor
4. Pastes HTML content
5. For each image:
- Selects WECHATIMGPH_1
- Scrolls into view
- Presses Backspace to delete
- Pastes image

# First-Time Setup
## Overview
When no EXTEND.md is found, guide user through preference setup.
**BLOCKING OPERATION**: This setup MUST complete before ANY other workflow steps. Do NOT:
- Ask about content or files to publish
- Ask about themes or publishing methods
- Proceed to content conversion or publishing
ONLY ask the questions in this setup flow, save EXTEND.md, then continue.
## Setup Flow
```
No EXTEND.md found
|
v
+---------------------+
| AskUserQuestion |
| (all questions) |
+---------------------+
|
v
+---------------------+
| Create EXTEND.md |
+---------------------+
|
v
Continue to Step 1
```
## Questions
**Language**: Use user's input language or saved language preference.
Use AskUserQuestion with ALL questions in ONE call:
### Question 1: Default Theme
```yaml
header: "Theme"
question: "Default theme for article conversion?"
options:
- label: "default (Recommended)"
description: "Classic layout - centered title with border, white-on-color H2 (default: blue)"
- label: "grace"
description: "Elegant - text shadows, rounded cards, refined blockquotes (default: purple)"
- label: "simple"
description: "Minimal modern - asymmetric rounded corners, clean whitespace (default: green)"
- label: "modern"
description: "Large rounded corners, pill headings, spacious (default: orange)"
```
### Question 2: Default Color
```yaml
header: "Color"
question: "Default color preset? (theme default if not set)"
options:
- label: "Theme default (Recommended)"
description: "Use the theme's built-in default color"
- label: "blue"
description: "#0F4C81 经典蓝"
- label: "red"
description: "#A93226 中国红"
- label: "green"
description: "#009874 翡翠绿"
```
Note: User can choose "Other" to type any preset name (vermilion, yellow, purple, sky, rose, olive, black, gray, pink, orange) or hex value.
### Question 3: Default Publishing Method
```yaml
header: "Method"
question: "Default publishing method?"
options:
- label: "api (Recommended)"
description: "Fast, requires API credentials (AppID + AppSecret)"
- label: "browser"
description: "Slow, requires Chrome and login session"
- label: "remote-api"
description: "Fast, tunnels WeChat API calls through SSH to a server whose IP is on the WeChat allowlist"
```
If the user selects `remote-api`, prompt for `remote_publish_host` and (optionally) `remote_publish_user`, `remote_publish_identity_file`. These can also be filled in later by editing EXTEND.md.
### Question 4: Default Author
```yaml
header: "Author"
question: "Default author name for articles?"
options:
- label: "No default"
description: "Leave empty, specify per article"
```
Note: User will likely choose "Other" to type their author name.
### Question 5: Open Comments
```yaml
header: "Comments"
question: "Enable comments on articles by default?"
options:
- label: "Yes (Recommended)"
description: "Allow readers to comment on articles"
- label: "No"
description: "Disable comments by default"
```
### Question 6: Fans-Only Comments
```yaml
header: "Fans only"
question: "Restrict comments to followers only?"
options:
- label: "No (Recommended)"
description: "All readers can comment"
- label: "Yes"
description: "Only followers can comment"
```
### Question 7: Save Location
```yaml
header: "Save"
question: "Where to save preferences?"
options:
- label: "Project (Recommended)"
description: ".baoyu-skills/ (this project only)"
- label: "User"
description: "~/.baoyu-skills/ (all projects)"
```
## Save Locations
| Choice | Path | Scope |
|--------|------|-------|
| Project | `.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | Current project |
| User | `~/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md` | All projects |
## After Setup
1. Create directory if needed
2. Write EXTEND.md
3. Confirm: "Preferences saved to [path]"
4. Continue to Step 0 (load the saved preferences)
## EXTEND.md Template
### Single Account (Default)
```md
default_theme: [default/grace/simple/modern]
default_color: [preset name, hex, or empty for theme default]
default_publish_method: [api/browser/remote-api]
default_author: [author name or empty]
need_open_comment: [1/0]
only_fans_can_comment: [1/0]
chrome_profile_path:
# Remote API publishing — only fill in if default_publish_method is remote-api
# or you plan to pass --remote on the CLI.
remote_publish_host:
remote_publish_user:
remote_publish_port:
remote_publish_identity_file:
remote_publish_known_hosts_file:
remote_publish_strict_host_key_checking:
remote_publish_connect_timeout:
remote_publish_proxy_jump:
```
Raw `ssh` / `scp` options are intentionally not supported; only the typed keys above are honored. Authentication is SSH key only.
### Multi-Account
```md
default_theme: [default/grace/simple/modern]
default_color: [preset name, hex, or empty for theme default]
accounts:
- name: [display name]
alias: [short key, e.g. "baoyu"]
default: true
default_publish_method: [api/browser/remote-api]
default_author: [author name]
need_open_comment: [1/0]
only_fans_can_comment: [1/0]
app_id: [WeChat App ID, optional]
app_secret: [WeChat App Secret, optional]
# Remote API publishing (optional, per-account override of globals)
remote_publish_host:
remote_publish_user:
remote_publish_identity_file:
- name: [second account name]
alias: [short key, e.g. "ai-tools"]
default_publish_method: [api/browser/remote-api]
default_author: [author name]
need_open_comment: [1/0]
only_fans_can_comment: [1/0]
```
## Adding More Accounts Later
After initial setup, users can add accounts by editing EXTEND.md:
1. Add an `accounts:` block with list items
2. Move per-account settings (author, publish method, comments) into each account entry
3. Keep global settings (theme, color) at the top level
4. Each account needs a unique `alias` (used for CLI `--account` arg and Chrome profile naming)
5. Set `default: true` on the primary account
## Modifying Preferences Later
Users can edit EXTEND.md directly or delete it to trigger setup again.

| `--content <text>` | Article content (max 1000 chars, auto-compressed if too long) |
| `--image <path>` | Single image file (can be repeated) |
| `--submit` | Save as draft (default: preview only) |
| `--profile <dir>` | Chrome profile directory |
## Auto Title/Content from Markdown
When using `--markdown`, the script:
1. **Parses frontmatter** for title and author:
```yaml
---
title: 文章标题
author: 作者名
---
```
2. **Falls back to H1** if no frontmatter title:
```markdown
# 这将成为标题
```
3. **Compresses title** to 20 characters if too long:
- Original: "如何在一天内彻底重塑你的人生"
- Compressed: "一天彻底重塑你的人生"
4. **Extracts first paragraphs** as content (max 1000 chars)
## Image Directory Mode
When using `--images <dir>`:
- All PNG/JPG files in directory are uploaded
- Files are sorted alphabetically by name
- Naming convention: `01-cover.png`, `02-content.png`, etc.
## Constraints
| Field | Max Length | Notes |
|-------|------------|-------|
| Title | 20 chars | Auto-compressed if longer |
| Content | 1000 chars | Auto-compressed if longer |
| Images | 9 max | WeChat limit |
## Example Session
```
User: /post-to-wechat --markdown ./article.md --images ./xhs-images/
Claude:
1. Parses markdown meta:
- Title: "如何在一天内彻底重塑你的人生" → "一天内重塑你的人生"
- Author: from frontmatter or default
2. Extracts content from first paragraphs
3. Finds 7 images in xhs-images/
4. Opens Chrome, navigates to WeChat "图文" editor
5. Uploads all images
6. Fills title and content
7. Reports: "Image-text posted with 7 images."
```
## Scripts
| Script | Purpose |
|--------|---------|
| `wechat-browser.ts` | Main image-text posting script |
| `cdp.ts` | Chrome DevTools Protocol utilities |
| `copy-to-clipboard.ts` | Clipboard operations |

# 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
```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 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`, `remote_publish_host`, `remote_publish_user`, `remote_publish_port`, `remote_publish_identity_file`, `remote_publish_known_hosts_file`, `remote_publish_strict_host_key_checking`, `remote_publish_connect_timeout`, `remote_publish_proxy_jump`.
**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
```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 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>`:
```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
```
## Remote API Publishing
`wechat-api.ts` supports a `remote-api` mode that tunnels WeChat API calls through an SSH SOCKS5 dynamic port forward to a server whose IP is on WeChat's allowlist. Markdown rendering, image processing, draft assembly, and HTML rewriting still happen locally; only outbound HTTPS calls to `api.weixin.qq.com` traverse the tunnel. No files are written to the remote host and `AppSecret` never leaves the local process. The remote host needs only `sshd` and outbound network access.
### Per-Account Configuration
```md
default_theme: default
default_color: blue
default_publish_method: browser # browser remains the default
accounts:
- name: 宝玉的技术分享
alias: baoyu
default: true
default_publish_method: api
default_author: 宝玉
app_id: your_wechat_app_id
app_secret: your_wechat_app_secret
- name: AI工具集
alias: ai-tools
default_publish_method: remote-api
default_author: AI工具集
app_id: your_ai_tools_app_id
app_secret: your_ai_tools_app_secret
remote_publish_host: ai-tools-server.example.com
remote_publish_user: deploy
remote_publish_port: 22
remote_publish_identity_file: /home/me/.ssh/id_ed25519
remote_publish_known_hosts_file: /home/me/.ssh/known_hosts
remote_publish_strict_host_key_checking: accept-new
```
Account-level `remote_publish_*` values override top-level globals. CLI `--remote-*` flags override both.
### CLI Usage
```bash
# Use the account's default_publish_method (remote-api here):
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme default --account ai-tools
# Force remote mode regardless of default_publish_method:
${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme default --account baoyu --remote --remote-host other-server.example.com
```
### Security Notes
- Authentication is SSH key only. Passwords and `ssh-askpass` are not used.
- Only the typed `remote_publish_*` keys are read; raw `ssh` / `scp` options are intentionally not supported.
- The tunnel forwards raw TCP; TLS verification for `api.weixin.qq.com` is still performed end-to-end by the local process.
