-> **Markdown is the draft. HTML is what humans read. Your local agent writes it.** The agentic HTML editor — in the agentic era, you don't hand-edit docs anymore, so the output format should be what the reader actually wants: HTML.

> The detection strategy and per-CLI adapter shape are borrowed directly from [`nexu-io/open-design`](https://github.com/nexu-io/open-design) and [`multica-ai/multica`](https://github.com/multica-ai/multica): one privileged process spawns CLIs, JSON-line is the wire protocol, every CLI gets a thin adapter in [`next/src/lib/agents/argv.ts`](next/src/lib/agents/argv.ts).

项目主页: open-design.ai/html-anything/ —— 不用 clone 也能先看看 HTML Anything 长什么样、能干啥。
-> **Markdown 是草稿, HTML 才是给人读的成品 —— 让本地 agent 直接写 HTML。** Agent 时代的 HTML 编辑器 —— 既然你已经不亲手改文档、全都让 Claude 改了, 那 agent 的输出就该是读者真正想看的 HTML, 而不是中间态的 markdown。本地优先、零 API Key、复用你已经登录好的 CLI session —— **9 个 coding-agent CLI** 在 `PATH` 上自动识别（Claude Code · Cursor Agent · Codex · Gemini CLI · GitHub Copilot CLI · OpenCode · Qwen Coder · Aider · IBM Bob），驱动 **75 套 skill 模板** 和 **9 类可交付场景**（杂志文章 · Keynote PPT · 简历 · 海报 · 小红书 · 推特卡 · Web 原型 · 数据报告 · Hyperframes 视频）。一键复制到公众号 / 推特 / 知乎，或者下载 `.html` / `.png`。
