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 🙏

安装

npm install agentkit-core
# 或
pnpm add agentkit-core
# 或
yarn add agentkit-core

快速开始

Express

import express from 'express';
import { agentKit } from 'agentkit-core/express';

const app = express();

app.use(agentKit({
  baseUrl: 'https://example.com',

  // 带 AI 感知规则的 robots.txt
  robots: {
    rules: [
      { userAgent: '*', allow: ['/'] },
      { userAgent: ['GPTBot', 'CCBot'], disallow: ['/'] },
    ],
    sitemap: 'https://example.com/sitemap.xml',
  },

  // 声明内容政策
  contentSignals: {
    aiTrain: 'no',
    search: 'yes',
    aiInput: 'yes',
  },

  // 向 AI 代理提供干净的 Markdown
  markdown: { enabled: true },

  // A2A Agent 卡片
  agentCard: {
    name: '示例代理',
    description: 'example.com 的 AI 代理',
    version: '1.0.0',
    url: 'https://example.com',
    capabilities: { streaming: true },
  },

  // auth.md — 机器人如何进行身份验证
  authMd: {
    serviceName: 'Example',
    resourceServer: 'https://example.com',
    registrationFlow: 'agent-verified',
  },

  // 在首页自动注入 Link: 请求头
  linkHeaders: true,
}));

app.listen(3000);

Hono (Cloudflare Workers / Edge)

import { Hono } from 'hono';
import { agentKit } from 'agentkit-core/hono';

const app = new Hono();

app.use('*', agentKit({
  baseUrl: 'https://example.com',
  robots: { rules: [{ userAgent: '*', allow: ['/'] }] },
  contentSignals: { aiTrain: 'no', search: 'yes' },
  markdown: { enabled: true },
}));

export default app;

Next.js

// middleware.ts
import { createAgentKitMiddleware } from 'agentkit-core/nextjs';

export const middleware = createAgentKitMiddleware({
  baseUrl: 'https://example.com',
  contentSignals: { aiTrain: 'no', search: 'yes', aiInput: 'yes' },
  markdown: { enabled: true },
  linkHeaders: true,
});

export const config = {
  matcher: ['/((?!_next/static|_next/image|favicon.ico).*)'],
};

Cloudflare Workers

import { agentKit } from 'agentkit-core/cloudflare';

const kit = agentKit({
  baseUrl: 'https://example.com',
  contentSignals: { aiTrain: 'no', search: 'yes' },
  markdown: { enabled: true },
});

export default {
  fetch: kit.fetch(async (req, env, ctx) => {
    return new Response('你好,世界!');
  }),
};

Deno / Bun

import { agentKit } from 'agentkit-core/generic';

const kit = agentKit({
  baseUrl: 'https://example.com',
  robots: { rules: [{ userAgent: '*', allow: ['/'] }] },
  contentSignals: { aiTrain: 'no', search: 'yes' },
});

// Deno
Deno.serve(kit.handler(async (req) => new Response('你好!')));

// Bun
Bun.serve({ fetch: kit.handler(async (req) => new Response('你好!')) });

性能

agentkit-core零开销为设计原则:

  • O(1) 路由查找 — 使用 Map 而非正则表达式数组
  • 零运行时依赖 — 无需安装额外依赖,无兼容性风险
  • 静态响应 — 所有响应在启动时计算,而非每次请求时
  • Tree-shakeable — 仅导入您使用的功能
  • Edge 优先 — 原生支持 Cloudflare Workers、Deno Deploy、Vercel Edge
