WeChat Post Publisher 微信公众号发布引擎

wechat-post-publisher 是一个为开发者和技术内容创作者量身打造的工程化发布技能 (Skill)。它旨在彻底打通从「本地 Markdown 极客撰写」到「微信公众号草稿箱」的自动化发布链路。告别繁琐的第三方网页工具复制粘贴、防止各种排版错乱和图片手动一张张上传的窘境，让你的重心彻底回归内容的创作。

---

🎯 核心原理 (Core Principles)

本工具并不仅限于一个简单的“文本 HTML 转换器”，它在内部构建了一条囊括状态隔离、素材热挂载、微信 API 强绑定的严谨流水线。

1. 深度定制的数据编译器 (Data Transformer)

微信公众号后台基于一套极其封闭受限的 HTML style 内联安全规范。为了让标准的 Markdown 无损过渡，底层注入了独立的转译引擎（即项目内的 super-md），并在编译节点做了两大劫持：

超链接接管：将所有通用外链（微信除了授权白名单文章外不支持直接外链跳转）自动拦截，并重构为文末统一排版的 「底部引文 (Citations)」 体系。
AST 样式扁平化：基于配置好的预设主题变量（如 grace 优雅风, simple 极简风），解析器会将对应的基础 CSS 样式树扁平化地计算并附着到每一个 HTML 底层元素的内容结构标签上，杜绝样式类污染。

2. 全自动多源媒体资产管控 (Autonomous Asset Uploads)

对于内容创作者最头疼的图片分发问题，引擎会动态生成一个正则抽象语法树提取所有的 <img src> 占位：

分离式上传机制：对被识别到的正文插图使用 media/uploadimg 流量通道打到云端，无缝将本地原始路径替换为微信专属 CDN 地址。
封面板块隔离：对封面图（无论是来自 Frontmatter 配置还是备用回退抓取的图 1），调用永久素材接口 (material/add_material) 做上传落库，拿回并挂载高权重的 media_id 以满足草稿图文规范结构的核心要求。

3. 多租户降维沙盒配置隔离 (Multi-Account Isolation)

系统通过极其克制的优先级层次模型覆盖状态机：

决策树优先级：CLI 终端参数 > 文章 Markdown YAML 头部 > 项目微隔离配置（.super-publisher/） > 跨项目系统配置（~/.super-publisher/）。
账户映射器：并在 EXTEND.md 之中原生支持 accounts 多租户字典块配置，仅仅通过一个简短的别名（Alias）即可实现切换不同的 AppID 以及鉴权策略上下文，从机制上杜绝对个人号、企业生产号“发错文、配串号”的乌龙。

---

💡 落地最佳实践 (Best Practices)

1. 固化完善的 Frontmatter 元数据

要把 AI 和工具当做协同机器来用，最稳妥的实践是把文章的属性前置。建议所有的新建发贴都在首部加上完整的元数据块：

---
title: "你的超赞文章标题：探索 AI 底层架构"
author: "超级发布团队"
summary: "千万字长文劝退？来看看这个工具带来的颠覆革命..."
coverImage: "./assets/cover-01.png"
---

拥有标准的头部元数据后，你只需要简单的触发一次工作流脚本，所有的验证拦截器都直接放行，极大加强流水线的无人值守能力（避免中断询问你缺失信息）。

2. 利用好系统原生相对路径 (Relative Pathing)

请避免在正文中写死磁盘的绝对路徑！建议你在文章同级目录下新建一个类似 /images 分组来存放插图。技能引擎以 Markdown 所在的相对目录为根路由进行自动解包寻址：

正确范式：![架构蓝图](./images/infra-map.png)

这能保证不仅在工具执行时平滑运作，更意味着你在不同的电脑之间拉取这个版本库（Git）也依旧能够做到完全通用。

3. 放心地使用无修饰的原生 Markdown 外链

写技术分享一定要带上代码地址或引申阅读，无需刻意逃避。针对微信的封控，本引擎自带的 Citation Transformer 已经搞定了一切。当你无所顾忌地写下 [阅读参考](https://github.com/guanyang/... ) 时，在最终排版发布之后，文中会巧妙地被加上一个右上角角标序号，并在文章尽头生成完美的「参考资料引文说明」底栏区。

4. 复杂环境执行防撞墙前排检查

如果在全新的办公设备第一次使用，或者在企业极客流 CI/CD 中拉起容器调用，你应当先借用它自带的脚本扫描仪排雷：

npx bun skills/wechat-post-publisher/scripts/check-permissions.ts

用来提前筛查底层编译器 Bun，以及剪接版、API 安全证书的健壮度合规水平。

🤖 智能化交互与使用范例 (Agent Prompts)

作为被大模型（如 Claude 或其他大语言终端）原生集成的极客技能 (Skill)，你不再需要亲手执行冷冰冰的代码，更推荐使用纯正的自然语言或智能指令触发它。大模型会为你自动处理所有的逻辑匹配与报错诊断。

以下是最高效唤起本系统工作流的 4 种主流（人机对话 Prompt）示例模式：

场景 1：极客风格的一键指令推流 (Slash Command)

如果你明确知道路径且不想废话，直接组合快捷指令串，Agent 便会静默替你走完全套流水线。

/wechat-post-publisher 文章 --markdown ./docs/article.md --theme modern

场景 2：模糊参数推断式口语下发

抛弃对参数名刻板的记忆，让 AI 自己去理解意群要求并自动匹配属性集。

"帮我把项目根目录下的 `release-note.md` 发布到公众号草稿箱里去。由于这篇是关于架构重构的，排版我想要现代冷峻一点的感觉，主题帮我换成 `simple`，颜色指定黑白调。发布完把文章底稿链接告诉我！"

场景 3：多租户身份的无缝脱靶式投递

依托于配置好的不同账户物理上下文（要求底层 EXTEND.md 存在 alias 别名编织）。

"这篇年终总结非常重要，我们要拿官方宣发号去发。去调那篇刚写完的文章发出去，同时千万记得在后台切走环境变量，用 `--account super-main` 的独立身份传过去哦！"

场景 4：“创作->作图->排版上架”的超级闭环流

这是将业务 API 改造成 AI Skill 后真正的价值释放点！你完全可以让大模型成为独揽图文产研全栈的主编。

"昨天从 GitHub 拉取的这个项目架构有点复杂，请先通读它然后用大白话给我生成一篇 800 字的解析长文，然后顺便作一幅代表数据矩阵和代码交织的酷炫 16:9 配图存入 `./assets/` 中。整理完毕后，不再需要过问我，直接通过 `wechat-post-publisher`，把这图挂进头图里作为封面，以 grace 优雅风，提交到我的微信号后台做一个新草稿！"

---

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: 超级发布团队
    alias: super
    default: true
    default_publish_method: api
    default_author: 超级发布
    need_open_comment: 1
    only_fans_can_comment: 0
    app_id: your_wechat_app_id
    app_secret: your_wechat_app_secret
  - name: 研发工具箱
    alias: dev-tools
    default_publish_method: browser
    default_author: 研发工具箱
    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}:

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. .super-publisher/.env with prefixed key WECHAT_{ALIAS}_APP_ID 4. ~/.super-publisher/.env with prefixed key 5. Fallback to unprefixed WECHAT_APP_ID / WECHAT_APP_SECRET

.env multi-account example:

# Account: super
WECHAT_SUPER_APP_ID=your_wechat_app_id
WECHAT_SUPER_APP_SECRET=your_wechat_app_secret

# Account: dev-tools
WECHAT_DEV_TOOLS_APP_ID=your_dev_tools_wechat_app_id
WECHAT_DEV_TOOLS_APP_SECRET=your_dev_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 dev-tools
${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <file> --theme default --account super
${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown <file> --images ./photos/ --account super

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 `super-publisher/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 `.super-publisher/.env`

Troubleshooting

Issue	Solution
Missing API credentials	Follow guided setup in Step 2 of the main workflow
Access token error	Check if API credentials are valid and not expired
Not logged in (browser)	First run opens browser - scan QR to log in
Chrome not found	Set `WECHAT_BROWSER_CHROME_PATH` env var
Title/summary missing	Use auto-generation or provide manually
No cover image	Add frontmatter cover or place `imgs/cover.png` in article directory
