Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Reusable runtime and provider toolkit for building AI-native CLIs with stable machine contracts and terminal-backed automation.

Readme

metacli

面向 AI-native CLI 的可复用运行时与 provider 工具集,重点解决“稳定机器契约”和“终端自动化底座复用”这两件事。

English README

它解决什么问题

当一个 AI CLI 从单脚本演进成真实产品后,通常会同时踩到三类坑:

| 问题 | 常见失效方式 | metacli 的处理方式 | | --- | --- | --- | | CLI 契约不稳定 | 人能用,智能体不能可靠调用 | core 统一 JSON / error / spec / doctor | | 终端自动化被重复实现 | 每个项目都复制 AppleScript / PowerShell 边角逻辑 | provider-* 模块集中维护平台能力 | | 业务流程和环境控制混在一起 | 产品语义绑死在 terminal 细节上 | terminal-runtime / codex-runtime 明确分层 |

  runtime --> win32["provider-win32"]
  runtime --> core["core"]

模块结构

| 源码模块 | 作用 | 导入路径 | | --- | --- | --- | | src/core | JSON 辅助、错误模型、CLI spec/doctor helper | @duo121/metacli/core | | src/terminal-runtime | provider 注册、snapshot、target resolve、运行时编排 | @duo121/metacli/terminal-runtime | | src/provider-darwin | Apple Terminal / iTerm2 自动化 | @duo121/metacli/provider-darwin | | src/provider-win32 | Windows Terminal / Command Prompt 自动化 | @duo121/metacli/provider-win32 | | src/codex-runtime | Codex 会话 attach / launch / prompt / capture | @duo121/metacli/codex-runtime | | src/create-metacli | 当前提供 starter manifest,后续可扩成脚手架 | @duo121/metacli/create-metacli |

metacli 只发布一个 npm 包。上面这些是包内源码模块,通过 subpath exports 暴露,不是独立发布的子包。

为什么要有 terminal-runtime

@duo121/metacli/terminal-runtime 不是“多出来的一层产品包”,而是夹在 provider 和应用之间的运行时层。

| 层 | 职责 | 为什么要独立出来 | | --- | --- | --- | | core | JSON、错误模型、spec、doctor helper | 不应该带 terminal 语义 | | provider-darwin / provider-win32 | 平台相关自动化 primitive | 应该贴近 AppleScript / PowerShell 细节 | | terminal-runtime | 统一 session 模型、provider registry、snapshot merge、target resolve、capability check、open/send/focus/press 编排 | 避免每个应用都自己拼装 provider 和重复运行时逻辑 | | codex-runtime | Codex 会话级流程 | 比原始 terminal control 更高一层 | | 应用层 | 产品行为 | 不应该知道平台边角细节 |

如果没有 terminal-runtime,每个应用都得自己重复做这些事:

  • 根据当前平台挑 provider
  • 把多个 provider 的 snapshot 合成统一模型
  • 从 selectors 里 resolve 出唯一 target
  • 在 mutating action 前检查 capability
  • 在不同 provider 之间统一 open/send/focus/press/capture 的调用方式

这部分明显是可复用运行时,不属于业务层,也不属于单个 provider,所以单独作为包内导出模块是合理的。

| 能力 | Darwin | Win32 | 备注 | | --- | --- | --- | --- | | snapshot / list | 支持 | 支持 | 统一输出 window/tab/session 模型 | | resolve target | 支持 | 支持 | 适合 AI 做精确定位 | | send text | 支持 | 支持 | macOS 侧可走 tty/native,Windows 侧走 UI Automation | | press keys | 支持 | 支持 | 当前统一 enter / return | | capture visible output | 支持 | 支持 | macOS 原生抓取,Windows 尽力抓取可见文本 | | focus session | 支持 | 支持 | provider 内部处理 | | open new window/tab | 支持 | 部分支持 | Windows 新开窗口/标签仍待补完 | | close target | 支持 | 支持 | cmd 为窗口级关闭 |

安装

npm install @duo121/metacli

快速开始

node -e "import('@duo121/metacli/provider-darwin').then(console.log)"
import { createDarwinTerminalRuntime } from "@duo121/metacli/provider-darwin";

const runtime = createDarwinTerminalRuntime();
const target = await runtime.resolveTarget({
  currentWindow: true,
  currentTab: true,
  currentSession: true,
});

await runtime.sendText(target, "codex", { newline: true });

校验命令

| 命令 | 用途 | | --- | --- | | npm test | 运行导出、runtime、codex helper、starter manifest 的集成测试 | | npm run pack:check | 对单一发布包执行 npm pack --dry-run |
